Description

The present invention relates to the field of mechanization of track facilities of railway transport and can be used when disassembling the links of the rail-sleeper lattice of the railway track, mainly with reinforced concrete sleepers, sorting or link repair; lines at the production bases of track machine stations.

A known method of disassembling the links of the track lattice of the railway track, mainly with reinforced concrete sleepers (ed. St. USSR No. 658205, ЕВВ 29/24) and the line sorting line (ET Lonchakov, BP Petropavlovsky. Track machines for linking and linking operations - M .: Transport, 1984. - p.157-160, Fig. 131, 133), where the separation of the linings from the sleepers is carried out on a link suspended from the rails. The mass of the sleepers detachable from the pads helps not to turn the embedded bolts in the sleeves of the sleepers and to separate it from the pads. However, it is difficult to put on the socket wrenches of the wrench spindles on the nuts of the bolts because of the close proximity of the terminals and the weight of the sleepers is not enough to separate it from the pads .

A link repair line is known (Pat. RF No. 2210654, ЕВВ 29/24, B65G 25/04, 35/08), where the disassembly of the links with their subsequent assembly from old-fashioned materials is carried out on satellite carts moved along a closed rectangular route. Separation of the linings from the sleepers is carried out by the corresponding unit when a satellite trolley is fed to it, on which the terminal-bolt fastening of the rails to the sleepers is preliminarily made and the rails are removed. The unit contains a portal, enclosing a satellite trolley supplied to it with sleepers placed on it in one layer with lining attached to them, a frame with working bodies mounted on it.

A known unit of the lining compartment (ed. St. USSR No. 1081256, ЕВВ 29/28; Link assembly and linking complexes of industrial bases PMS. - M.: Route, 2006. - p. 87-88, Fig. 2.20 - taken as a prototype), containing mounted on a portal frame that contains sleepers in one layer with lining attached to them, sleepers centralizers for interacting with their ends, wrenches with vertically movable socket wrenches of their spindles, vertically movable lining grips, sleepers. The vertically movable body of the spindle of the wrench with a socket wrench with its upper fixed body is connected by means of a power cylinder for vertical movement of the socket wrench. Vertically movable grips of the pads are made in the form of grippers vertically moved by means of power cylinders, the gripping L-shaped levers of which, by means of their power cylinders, interact with the terminal grooves of the pads for their gripping and subsequent suspension of the sleepers. The sleeper latch is rigidly mounted on the unit frame at the height of the sleepers.

Suspension of the sleepers by its linings and fixing it in a suspended state allows you to unscrew the nuts of the embedded bolts without turning them, while the access keys to the nuts are free due to the lack of terminal fastening of the rail, which increases the reliability of finding the nut when putting on the socket wrench.

The presence of sleepers centralizers in the aggregate allows you to set the cross axis of the sleepers along the axis of the aggregate to install the sleepers with your linings under the vertically movable grips of the liners, and the nuts of the bolts for the spindles of the wrenches, but the lack of a device for installing the longitudinal axis of the sleepers perpendicular to the longitudinal axis of the aggregate does not provide sufficient accuracy for installing the sleepers linings for vertically movable grips of the linings, and nuts for the embedded bolts under the wrench spindles.

Vertical movement of the socket wrench by means of a power cylinder allows you to reliably put the key on the nut, but the rod of the power cylinder is forced to compensate for the reactive moment that occurs when the nut is unscrewed, which leads to its twisting relative to the cylinder mount.

The gripping L-shaped levers of the vertically movable grippers of the pads, when interacting with the terminal grooves of the pads, allow the sleeper to be grasped by the pads and hung out with the placement of the nuts of the bolts under the spindles of the wrenches. However, the process of gripping the pads for their terminal grooves is quite lengthy, in addition, when disassembling the links, a significant number of pads with cracks or even broken ones are observed (7-20%, depending on the condition of the rail being disassembled), which aggravates the gripping process followed by loosening the nuts of the embedded bolts. The mass of the sleepers is often not enough to separate it from the linings, which are very tightly glued to the sleepers due to wear of the head-pads during the operation of the track.

A tie fastener rigidly mounted at the height of the railway sleepers reliably fixes it from displacements caused by the reactive moment when the wrenches work. However, the subsequent lowering of the sleepers may violate its position at the location.

The linings and their attachment elements are placed in sleepers (the space between adjacent sleepers), from where they are removed only after removing the sleepers.

An aggregate for separating the linings is required with a quick and reliable grip of the linings, ensuring their reliable separation from the sleepers at the time of reliable unscrewing of the nuts of the bolts with the oriented placement of sleepers, catching and removing the linings and the associated elements for their attachment to sleepers.

To do this, in the known unit for separating the linings of the sorter line, which is mounted on a portal frame, containing mainly a satellite carriage with sleepers placed on it in one layer with lining attached to them, sleepers centralizers for interacting with their ends, wrenches with vertically movable by means of power cylinders with the socket wrenches of their spindles, vertically movable by means of power cylinders, the grips of the linings, the sleeper latch, retractable side sleepers are mounted on the frame, vertically movable housings with end wrenches of the wrench spindles are connected to vertically motionless housings by means of lamellar sleeve chains, vertically movable grips of the liners are arranged to interact with the butt surfaces of the liners, the sleeper lock is vertically movable by means of a power cylinder, and the unit is equipped with a device for trapping and removing linings and related elements attaching them to the sleepers (fasteners).

The vertically movable lining of the lining is a gripping device suspended from the power cylinder in the form of a power cylinder, on the body of which two-arm levers are pivotally mounted with their upper shoulders, the lower shoulders of which are equipped with pressure gripping plates for interaction with the end surfaces of the lining, and the middle parts are connected to the intermediate rods with his stock.

The device for collecting and removing linings and related elements of their attachment to sleepers (fasteners) is made in the form of a transverse conveyor arranged across the satellite trolley and underneath it, joined with a longitudinal vertically inclined conveyor to move the fasteners into the storage tank.

The presence of a portal frame that encloses a satellite carriage with sleepers placed on it in one layer with lining attached to them, with sleepers centralizers mounted on it for interaction with their ends, retractable side sleepers, wrenches with vertically movable socket wrenches of their spindles, vertically movable grippers of the pads with the possibility of interaction with the end surfaces of the pads, vertically movable sleeper latch allows for periodic movement of the satellite car with a stop Orient each sleeper at its processing position, orient each sleeper on the satellite trolley with its transverse axis along the axis of the aggregate and its longitudinal axis perpendicular to the longitudinal axis of the aggregate, reliably unscrew all nuts of the bolts with a reliable separation of the linings from the sleeper without moving it from the oriented position, drop the fasteners in the interval between the sleepers when cleaning the processed sleepers with the supply of the next sleepers to the position of its processing.

The presence of retractable side sleepers just allows you to stop the sleeper at the position of its processing, to orient its longitudinal axis perpendicular to the longitudinal axis of the unit, to skip the processed sleeper.

The connection of vertically movable housings with power cylinders with end wrenches of the wrench spindles with vertically motionless housings by means of plate sleeve chains allows to completely relieve the power cylinders from the unusual twisting forces between the rod and the cylinder body that occur due to reactive torque when unscrewing the nuts of the bolts. The lamellar bushing chain fully accepts these loads due to its lateral stiffness, without interfering with the vertical movement of the socket wrench during its longitudinal folding-folding.

Performing vertically movable by means of power cylinders grips of the pads for the possibility of their interaction with the end surfaces of the pads allows you to simply and reliably grab the pads for their free end surfaces with the subsequent application of a vertical load to ensure that the bolts in the jacks do not turn when unscrewing their nuts with the associated separation of the pads from the sleepers .

The implementation of the sleeper retainer vertically movable by means of a power cylinder allows you to rigidly fix the oriented sleeper at the position of its processing, ensuring its immobility when unscrewing the nuts of the bolts and separating the linings from it.

The equipment of the unit with a device for capturing and removing fasteners allows you to catch and remove fasteners directly from the processing position of the sleepers during operation of the unit.

Grip of the lining, which is a gripping device suspended from the power cylinder in the form of a power cylinder, on the body of which two-arm levers are pivotally mounted with their upper shoulders, the lower shoulders of which are equipped with pressure gripping plates for interacting with the end surfaces of the lining, and the middle parts are connected to its intermediate rods the rod allows you to quickly clamp the lining for its end surfaces with a pressing force necessary to separate the lining with its vertical relative about sleepers moving followed by quick release of the lining.

The implementation of the device for collecting and removing fasteners in the form of a transverse conveyor arranged across the satellite trolley and underneath it, joined with a longitudinal vertically inclined conveyor to move the fasteners to the storage tank, allows you to quickly remove the fasteners from the processing position of the sleepers and store them in the tank for their further shipment .

The unit 1 for separating the pads of the sacking line, which includes satellite trolleys 3 moving along the path 2 in the direction of arrow G, the terminal separation unit 4, the rail pickup 5, comprises a portal frame 6, containing a satellite trolley 3 with sleepers 7 placed on it in one layer with pads 8 attached to them, with centralizers 9 of sleepers 7 mounted on it, retractable side sleepers 10, wrenches 11 with spindles 12, equipped with socket wrenches 13, grips 14 of the pads, and a sleeper latch 15.

Centralizers 9 sleepers 7 are mounted on pivotally mounted on the frame and driven by power cylinders 16 levers 17 stops 18 for their interaction with the ends of the sleepers.

The retractable lateral sleepers 10 are pivotally mounted on the frame and driven by the power cylinder 19, the stop levers 20 for interacting with the lateral surface of the sleepers to stop and level or skip the sleepers with the arms raised.

Each spindle 12 of the nutrunners 11 is a vertically movable housing 22 with a socket wrench 13 that is moved along a spline shaft 21 rotatable by a screwdriver and is connected with a vertically stationary housing 23 by a power cylinder 24 and a plate sleeve chain 25 to protect the power cylinder from twisting forces of the reactive moment when unscrewing nuts 26 of a bolt.

The latch grip 14 is a power cylinder 28 suspended from the master cylinder 27, on the body of which two shoulders 29 are pivotally mounted with their upper shoulders, the lower shoulders of which are provided with pressure gripping plates 30, and the middle parts are connected to its rod 32 via intermediate rods 31.

The sleeper latch 15 is a vertical trough 34 driven by a power cylinder 33 with a section corresponding to the section of the middle part of the sleepers.

The unit is equipped with a device for capturing and removing linings and other relevant fastening elements, which is arranged across the satellite trolley and underneath it a transverse belt conveyor 35, which is joined with a longitudinal vertically inclined conveyor 36 to move the fasteners into the storage tank 37.

The unit for separating the pads of the linking line operates as follows.

Satellite cart 3 after the rails are unblocked by the aggregate 4 and removed by the rail pickup 5 from the disassembled link of the track grid placed on it, moves to the lining separation unit 1, where, when the satellite trolley is periodically moved from the sleepers to the sleepers, the next sleeper is fed to the position of separating the linings from it.

At the position of separating the linings, the sleeper, when it rests with its lateral surface in the retractable side stops 10, is set with its longitudinal axis perpendicular to the longitudinal axis of the aggregate, and when centralizers 9 are triggered, it is set with its transverse axis along the longitudinal axis of the aggregate and, thus, is placed with its linings under the grips 14 lining and nuts of bolts under the spindles of 12 wrenches.

Trigger to lower the chute 34 of the latch 15 of the sleepers and the sleepers are securely fixed in the oriented position.

The grippers 14 of the pads are lowered onto the pads and they are gripped by pressing the gripping plates 30 of their end surfaces (FIGS. 6 and 7). The clamping force is controlled by the pressure of the working medium in the power cylinder 28.

The nuts 26 of the embedded bolts are lowered (according to arrows D) and the socket wrenches 13 of the wrench spindles are closed on them.

The nuts of the bolts are unscrewed while the pads are lifted (arrow E), which is facilitated by not turning the bolts when unscrewing their nuts and separating the pads from the sleepers, which is securely held by the sleeper lock and also reliably quenches the reactive moment when the nuts are unscrewed.

The retractable side sleeper stops 10 and the sleeper latch 15 are lifted, centralizers 9 are retracted, the processed sleeper is removed by the satellite trolley from the position of the lining separation and, at the beginning of its movement, before the next sleepers approach, the grippers 14 of the lining are pressed, the lining, nuts, washers are dropped onto the cross conveyor 35, by which they move to the longitudinal vertically inclined conveyor 36 and further to the storage tank 37. Retractable lateral sleepers 10 are lowered to stop and orient the next sleepers on and lining separation positions.

The proposed unit for separating linings allows you to reliably unscrew the nuts of the embedded bolts, reliably separate the linings from the sleepers during their quick and reliable grip, catch and place the linings and related fasteners in the storage tank.
