Description

(54) COUNTERBOARD MOBILE LOADER

I

The invention relates to the forest industry, in particular to the logging industry for loading xJBicTOB onto a vehicle and can be used in other areas for loading long loads.

The counterbalance system of the maxillary loader is known, which consists of a counterweight that moves relative to the axes on the loader frame and is equipped with a mechanism for its movement associated with the lifting mechanism of the maxillary support of the maxillary grip 1.

However, the device increases the size of the loader.

The purpose of the invention is to reduce the dimensions of the building.

The goal is achieved by the fact that the counterweight is equipped with a toothed rack, and its mechanism of movement is made of interlocking chain stars, the first of which is rigidly mounted on one of the support levers, and the second on the frame of the loader equipped with a gear wheel mounted on the second sprocket and co-operating with counter-toothed rack.

FIG. 1 shows the loader at the moment of loading the storage pocket, general view; in fig. 2 - the same at the time of loading; on r. 3 - a device for moving the counterweight corresponding to the angle of rotation of the support arms.

Claims (1)

The maxillary tractor loader includes an arrow turning in a vertical plane from power cylinders 1 arrow 2 with a handle 3 and a maxillary gripper 4 mounted rotatably with the help of hydraulic cylinders 5. The supporting arms 6 are driven in a vertical plane from power hydraulic cylinders 7 on which a hinge-mounted -bearer storage 8 with a lateral support 10 tilted under the action of a hydraulic cylinder 9. The support arms 6 are interconnected by a jumper 11 and are hinged to the frame 12 equipped with a counterweight 13. The implementation of the counterweight 13 makes it possible to adjust the tilting depending on the weight of the spindle | about the moment that occurs when loading cargo, the value of the reducing moment without increasing the weight of the counterweight. The movement of the counterbalance 13 includes an asterisk 14, which is mounted with the levers 6 on the axis 15 and connected by means of a chain 16 with an asterisk 17. The asterisk 17 is rigidly connected to the gear wheel 18, which engages with the tooth of the rail 19, having the ability to move guides 20. At the end of the rail 19, a counterweight is installed. 1 The maxillary tractor loader works as follows. Capture lengthy loads. by the maxillary gripper 4, after which, under the action of the power cylinders 1, the piston 2 is turned in a vertical plane, lifting the weight, and then turning the handle 3 by the hydraulic cylinders 5, lowering it into the pocket accumulator 8. This operation is repeated until the pocket accumulator 8 is fully loaded, after which cargo is transported to the place of loading. Loading dpi-sized goods onto a vehicle produced by a storage pocket 8 | which is spherically mounted on support arms 6 interconnected by jumper 11 and rotating in a vertical plane under the action of power hydraulic cylinders 7. At the same time, the storage pocket 8 moves only in a vertical plane due to its hinge fastening on two support arms 6. Supporting the levers 6 are hinged on the frame 12, equipped with a movable counterweight 13. During the loading, the levers 6 rotate together with an asterisk 34 14 on asi 15. Rotation is transmitted using a chain 16 to an asterisk 17 and a gear wheel 18, P Turning back, the gear wheel 18 raises the rail 19 with the counterweight 13 fixed at the end and moving in the guides 20. Thus, a certain angle of the locking levers corresponds to the movement of the counterweight 13 to the given shoulder L. After stowing dsh (unloaded cargo onto the vehicle rack) 10 is tilted by the action of the hydraulic cylinder 9, and the loader moves forward, freeing the storage pocket 8, which returns to its initial position. The levers 6 rotate in the opposite direction and pull in the counterweight 13. Invention Formula The counterbalance system of the jaw loader consists of a counterweight guide that moves relative to the guide rail mounted on the loader frame and is equipped with a mechanism for its movement associated with the lifting mechanism of the jaw gripper differing from so that, in order to reduce its dimensions, the counterweight is equipped with a toothed rack, and its movement mechanism is made of interlocking sprockets, the first of which TCR is fixed on one of the support arms, and the second on the loader frame, provided with a toothed wheel ustanovlennm coaxially with the second sprocket and cooperating with a toothed p eykoy counterweight.
