Description

Track-measuring trolleys for measuring and recording the broadening and elevation of the path, equipped with receivers of the broadening of the path, the elevation of the path in the form of warders, and a writing instrument with constant pens, are known. Such well-known devices are bulky, complex in design and heavy.

The measuring trolley according to the invention is free from the indicated disadvantages. The essence of the invention lies in the fact that the receiver of the broadening of the path is made with spacer tube rods carrying two conical slide, interacting through an abutting wedge with a feather holder.

FIG. 1 shows a general view of the trolley from the end; in fig. 2 is a side view of it; in fig. 3 is a view of a receiver for side widening; FIG. 4-view it in plan.

The frame - / trolley is formed by a steel thin-walled tube, at the ends of which two moving wheels are mounted on ball bearings.

The right running wheel has a gear wheel on its body, transmitting the rotation to the tape mechanism.

The left wheel is held together with a pipe through a fiber spacer, which creates an isolation of one rail thread from the other.

Brackets are welded to the ends of the pipe, on the axles of which the hinged side bars 4 with two small wheels and two vertical rollers 6 can rotate. In the off position, the bars rotate in the hinges and are fixed along the main frame with a pin.

The wheel and roller of the rod are insulated from the main frame. In the working position, the cart moves along the way, resting on top of four traveling wheels; two vertical rollers and two inclined disks of a kts ts on internal gra-. m of heads of track rails and do not allow the truck to go off the rails.

The track broadening receiver consists of two inclined disks 7 rotating on ball bearings, the bodies of which are welded to the two tubular gauge bars 9, 70 inside the trolley frame by means of two kerchiefs 8. Measuring rods are moved in rails 11 fixed inside the frame of the cart.

and under the influence of two coil springs 12, 13 are constantly pressed to the ends of the frame. The inclined discs that fix the width of the track, associated with the measuring rods of the springs, are pressed against the inner face of the track rail heads.

The ends of the measuring tubes, located in the middle part of the tube frame of the trolley, have eyelets .1.4, to which cone sliders / О are fixed at the hinge, canted at an angle of 45 ° With the slope of the surfaces of the sliders of both tons, the abutment wedge / 6 interacts, lying, at the bottom of the w, ika 77 tape drive mechanism / rS, welded to the frame.

The presence of two spacer measuring tubes with tapered sliders and a wedge, resting on them, ensures that the wedge moves up (in plan) when the measuring tips approach each other under the action of the discs and vice versa downwards when the measuring tension diverges under the influence of the springs.

The wedge has a rod 7.9 with a roller resting on the horizontal shelf of the wedge. This rod moves in the guides 20 and is pivotally connected to the opposite arm of the angular lever 21. The long arm of the lever has a feather on its end to record the track width. This lever arm consists of two parts, in order to adjust the record, and a small coil spring is pressed toward the wedge, in order to eliminate backlash in the articulated joints of the lever.

Such a transmission system of the recording of the track width makes it possible to record it in full size, and the inclined measuring rollers are not rigidly connected to the trolley frame and abrupt changes in the track width in the joints do not cause impacts to the trolley frame, which ensures more stable work of the trolley mechanism and more accurate record of the elevation of the rails.

The mechanisms for measuring the elevated path consist of a mandrel 22 suspended in a casing on two ball bearings. The working length of the tomb is 800 .. m, that is, half of the calculated gauge. At the bottom, a leash, hingedly connected to the tiger's tail, is attached to the end of the tandem, which is connected at the end with a feather. The pen holder moves in two directions, these, which ensure the linear movement of the pen and more accurate recording in the longitudinal scale.

The adjustment of the elevation record is ensured by rearranging the engine mount in the long groove, as well as by changing the thickness of the gaskets at the base of the casing. When the trolley is removed from the track to allow the train to pass, the master is locked in the casing. In the non-working transport position, the tilting casing together with the tambour is translated into a horizontal position by turning around the hinge .V.- and secured by a screw 24 on the frame.

To control the correct recording of the lift, a liquid level with a circular P1 level is installed on the tube frame of the cart.

The drive 2 of the tape mechanism consists of a pair of cylindrical gears mounted on the body of the right-hand sprocket and a transfer roller with horizontal gear, with an off coupling at the trolley frame, two identical worm gearboxes at the right wall of the drawer of the ribbon-forming mechanism and two identical cylindrical uie spur on the axles of the drive roller and the winder of the tape mechanism. All these programs ensure uniform movement of the paper tape. The tape mechanism (parts not shown in the drawing) consists of a drive roller connected to the drive, a roller (coil), a clean tape, a tension roller, a winding roller and a pressure roller pressed against the drive roller. The belt is graphed by a ribbed roller pressed against a tension roller. The ridge roller is in the lower part in the inkwell and in contact with the felt pads soaked in paint. Reeling; the roller is rotated by a gear from the leading roller.

Between the tensioning and driving rollers, under the paper tape, there is a tablet for manual recording and marks on the tape at characteristic measurement points. The clean tape and reel rollers have removable flanges for conveniently loading the tape mechanism with a clean tape and removing the used tape. On the right side of the mounting of the reel of a clean tape there is a handle for winding the tape. Factory tape rolls harvested for a track-measuring trolley can be put on the roller of the coil without rewinding with preliminary removal of the coil flange.

On the right side of the winding roller there is a friction disk, which ensures the rotation of the roller with slippage with an increase in its working diameter.

For snoring cart spare parts, tools for fastening and adjusting cart mechanisms, grooved paint roller, ink and feather pencils, there is a tool box on the right side of the cart frame that is also designed for storing food for those working with the cart.

Before starting work on measuring the path, all mechanisms should be checked, adjusted, and the parts should be lubricated.

The check and adjustment of the trolley is carried out according to the trolley operation manual.

Periodically, in the process of working in the most characteristic places of the path, the recording of the cart is compared with

indications of the gauge of the track width and the liquid level of the carriage, and the actual condition of the track is checked using a manual template.

The work with the trolley along the track is done in the following order: the cart is mounted on the track, two side bars with front support and vertical rollers are moved away from the frame and secured to the rails with pins. The knobs of the pattern turning off mechanism are brought out of the off position and the inclined measuring disks are switched to the working position.

The casing of the taller with the tilt of the mechanism of elevation is installed and secured in a vertical position; the master is connected to its thrust, the locking pin of the bird makes the master in the working position. The tape drive coupling is turned on and the recording pens (pencils) are in good condition. The signal flag is fastened on the case of the mantel, the handle for pushing is inserted on the frame of the cart, and the cart moves with a measurement at a speed of 4-5 lm /// "g-. At the end of the measurements, the template and elevation mechanisms are turned off, both rods with side rollers are retracted to the trolley frame, and the trolley is removed from the track by the handles.
