SU301302A1 - A ROTARY MACHINE FOR FORMING A LOG BEAM - Google Patents

Description

The invention is intended for the formation of log beams when timber rafting on rivers and lakes and can be applied to sorting and rafting raids of various cargo turnover.

The known rafting machine contains pontoons, rafting and accumulative corridors, a rafting device with upper and lower racks and cable loops.

The purpose of the invention is to improve the quality of the formation of the nuchka. This is achieved by the fact that the upper pivot points of the hinge are mounted on the middle bridge, and the lower ones are rigidly fixed on the underwater beam. Moreover, the upper and lower posts are rotatable, and the cable loops can be opened with the help of a cable feeding mechanism consisting of a lock and fitted with blocks of casing mounted on and tanga and made movable along the guides.

FIG. 1 depicts the proposed compact rafting maschina; in fig. 2- a device for repacking the ends of the lower branches of the cables and a kinematic diagram of the operation of the maschina rafting device.

The raft maschine contains two parallel pontoons 1, connected by three transverse bridges. At the bottom of the front axle 2 there is a continuous brush blower 3. Together with the supercharger

a winch 4 is mounted on the front axle, connected by a troso-block system with two trolleys, on which vertical raft racks 5 are pivotally fastened.

move the winch 4 along the guides 6 laid along the maschina under the front 2 and middle 7 bridges. The middle bridge divides the corridors formed by the pontoons of the machine, accumulation 8 na and raft 9 corridors.

In the storage corridor there are equalizers 10 of the brush. Under water, the storage corridor is bounded by a pallet 11. A bundle is formed in the raft corridor of the maschina by two rafting cables} 2 and racks 5.

The cables 12 fasten the ends of their lower branches to the lower pillars 13, and the upper branches on the drum 14 of the rafting winch form a loop into which logs are fed from the accumulating corridor by the racks 5.

In order to reliably separate the rafting corridor from the accumulative corridor, as well as as an emphasis, when the beam is pressed, two pairs of pivot struts are used: the upper 15 and lower 13.

The upper posts are hinged on the stern of the middle iviocia, and the lower ones are rigidly fixed on the underwater beam 16. The main drive is turned in the direction of the cable loop (the upper stands are turned relative to the hinge mounted on the middle bridge, and the lower ones - together with the underwater beam). At the end of the log pass, the racks return to their original (vertical) position. To release the finished bundle from the cable loop, form a new cable loop, and hold the ends of the lower branches of the float-precise cables, a special device is designed to reposition the lower branches of the raft cables. It consists of two feeders for cables and two locks (for each raft cable according to the iodine-15 chi mechanism and a lock). The cable feed mechanism contains 17 guides 17 mounted on the aft part of the middle bridge, between which shtangi 18 are moved. On the shtangs, 20 clamps are fastened with 20 joints 19, the blocks rotate between the cheeks 20 and 21, the rods 12 are driven through the blocks (up or down) driven, connected to it by the spindle gear. On 25 both cheeks of a holder stops are welded. Since the holder with blocks can move relative to the upper level of the beam (or the level of the middle bridge), the position of the holder at the time of formation of the beam determines the angle 30 of the upper branches of the beams. The lock is located in the lower halves of the pivot posts and is a folding roller 22 rotating on an axis. One end of the axle has a shaped protrusion 23, into which 35 a pawl 24 enters, holding the roller in a working (horizontal) position. The other end is fixed on the end of the shaft 25. On the same shaft there is a splint 26, which is in engagement with the sector 27, hardened-40 on the axis 28 and having a protrusion 29. The dog 24 is rigidly fastened to the shaft 30, on which the levers 31 are fixed and 32. The lever 31 is constantly sonrikasaet with the lever 33, which is rigidly connected by means of the shaft with the fish-45 chagom 34. The lever 32 is constantly in contact with the lever 35. The ends of the lower branches of the cables with a horizontal nanozhenni roller 22 bend around it, and attached to the ends ropes of goods 36 do not allow them to go off the roller, so 50 as when nat SRI rope loads are stuck to the stops 37. When tilting the roller axis 22 down nutem rotation shaft 25, the lower branch cables with the slide and the roller 55 okazyvayuts osvo- boladennymi from racks. This is done by opening the cable loop to release the finished bundle. Works maschina as follows. The forest along the supply corridor of the sorting grid 60 is fed to the mashina by a transverse brush and is captured by the supercharger 3, which creates a multiplex gap in the accumulator corridor 8 of the rig. After a sufficient amount of wood (equal to the beam volume) 65 5 is set up, a winch of 4 racks is turned on, raft carts are transferred to the front axle, and the racks 5, which are fastened to them, slide along the logs and at the end of the course are lowered by the supercharger racks. At the same time, the chuck in the accumulation corridor is leveled with equalizer 10 and with the racks 5 is fed into the raft corridor 9. At the same time, the pivot stands are opened, and the supercharger continues to gain new batch of logs. The logs, the passage under the action of the racks 5 into the raft corridor are pulled by cables 12, which are wound up from the drums 14 of the raft winch under a certain tension, adjustable by a friction device. After passing the pillars 5 behind the pivot posts, the latter are closed. If it is necessary to re-feed the logs into the cable loop, the process is repeated. Since the cables 12 are iodine naty, the stands 5, feeding the logs into the cable loop, simultaneously form a bundle. Moreover, by changing the position of the cage with the blocks vertically, the optimum angle of convergence of the upper branches of the cables from the bundle is selected. If necessary, in order to improve the quality of the training, it can be additionally provided with the help of the raft cables. After formation, the beam is bound by one of the known methods. At the end of the bundling of the bundle, the drums 14 of the rafting hoist release the brakes and begin to lower the yoke with blocks, which, when it goes down, winds the cables 12 from the drums. the lever 34, which, through the lever 33 connected with it, by turning to the lever 31 rotates the shaft 30 and the pawl fixed on it 24. The pawl leaves the shaped protrusion 23, making it possible for the axis of the roller 22 to tilt down under the action of weights 36, turning the shaft 25. At the same time enpo zakrenlenna the shaft 25 rotates the sector schestern 26 27 It appears that the projection 29 on the yoke path. In addition, when the pawl is turning, the lever 32 sitting on the same shaft turns the lever 35, which is in the way of the clip, on the same shaft. In the event that the weight of the load is not enough to tilt the axis of the roller 22, the holder, upon further movement down, affects the roller and overturns it. In this case, the lower branches of the cables, together with the cargo, slide off the rollers and are released from the pillars, the holder lowers even lower (by the length of the roller) and the protrusion of the cheek 21 falls on the protrusion 29 in its path, turns the gear sector 27 associated with it, and around the axis 28, which with the help of scab

26 puts the axis of the roller 22 in a horizontal position.

Upon further movement of the yoke downward, the protrusion of the cheek 20 acts on the levers 35 and 32, as a result of which the shaft 30z rotates the doggie rigidly connected to it, which enters the shaped protrusion of the axis of the roller 22 and fixes this axis in a horizontal position.

After that, the cage with the blocks begins to rise upward and thanks to the hinge 19 bypasses the roller 22 from the inside, without hitting it, as well as the lever 34, and sets the SI in its original position. Since the cables 12 pass through the blocks of the cage, they are also provided on the inside of the roller. Simultaneously with the raising of the cage to its original position, the cables 12 begin to be wound on the drums 14 of the raft winch, and the ends of their lower branches, together with the loads, pass along the surface of the beam, fall from it and pull into the stops 37.

The bundle is released from the rope loop, and the machine is prepared for

the rafts of the next bundle, the multi-nozzles for which are prepared in the storage corridor. The finished bundle is pushed out of the raft corridor by a subsequent bundle during its rafting.
