Description

(54) LOADING UNLOADING DEVICE

VEHICLE FOR TRANSPORT

LONG DIMENSIONAL LOADS

The invention relates to the forest industry and can be used for coastal wood rafts.

A vehicle handling device for transporting long loads is known, comprising a frame, a side stand mounted on one side of the longitudinal axis of the vehicle, transverse guide and movable in said guide slide, equipped with a lever made rotatable in the transverse vertical plane of the transport means by means of the power cylinder 1.

However, the known device has insufficient performance handling.

The purpose of the invention is to improve the performance of loading and unloading.

This goal is achieved by the fact that the guide and the slide are rotatable in the transverse vertical planes of the vehicle, the axis of rotation of the guide being shifted relative to the longitudinal axis of the vehicle towards the rack, and the lever is configured to longitudinally move relative to the slide by means of said force cylinder.

FIG. 1 shows a vehicle with a loading and unloading device, general view; in fig. 2 is a section A-A in FIG. 1, before loading the goods; in fig. 3 - the same, before unloading the goods.

The vehicle consists of a tow truck 1 and trailers 2, connected by a telescopic gorge 3, allowing the distance between the trailers to be changed.

10 2 depending on the length of the rally and

transported beams, in addition, trailers 2 have the ability to move relative to the sections of the gable 3.

Each trailer 2 consists of a carrier

j frame 4 with stand 5. On the supporting frame 4 there is installed a transverse transverse guide 6, the pivot axis 7 of which is shifted to stand 5 relative to the calculated center of gravity of the total mass of the beam and guide 6. Connecting 6 yarn with rack 8 driven 8 The carriage 9 is moved along the guide 6 by means of a hydraulic actuator with a telescopic load gripping body mounted on it.

consisting of a slider 10 and a lever 11. The slider 10 can be installed at an angle to the direction of yushi 6 by means of an actuator 12, and the lever 11 - at an angle to the slider 10 by exosal positioning of the power cylinder 13 and the limiters 14 of the slider 10 and lever 11.

The device works as follows.

A set of packages of logs or logs is produced directly from the truck and railway couplings or from sorting racks and from storage pockets. For this, the vehicle is installed in close proximity to the forest transport or the sorting facility. The tracks 6 of the trailers 2 are oriented by the drives 8 in such a way that their ends of the open part are flush with the loading height of the horses or the bridge. The carriages 9 move along the guides 6 to the extreme right position, and at the same time the sliders 10 seconds are set to the horizontal position by means of the actuators 12.

At the end of the stroke, the carriages 9 are set in motion by the levers 11, which at the end of their stroke are set at the angle necessary to grip a stack of logs or whips, using power cylinders 13 and stroke limiters 14.

The packages are loaded by moving the carriages 9 in the opposite direction while simultaneously turning and setting the load-gripping bodies at an angle to the last actuators 12. At the end of the stroke of the carriages 9, the package of logs is pressed against the uprights 5. The following packages are loaded in the same way. The compression of packages into a bundle is carried out with the horizontal position of the guides 6 by means of the carriages 9 and the load gripping bodies, which together form the stand 5, form the necessary beam shape.

At the end of the formation of the bundle, binding sets are superimposed on it. After this operation, the bundle is transported for placing in a raft.

When laying the beam, the slide blocks 10 are set to a horizontal position, and the levers 11 are set to their original position. The actuator 8 guides 6 are rotated through a large angle of friction and sufficient for an arbitrary unloading of the beam, while the sliders 10 serve as a continuation of the guides 6

and perform the functions of the outriggers. At the end of the unloading, the carriage 9 with the load gripping bodies and the guides 6 are set to their initial position.

The economic effect of the introduction of the proposed device is due to

eliminating just forest transport, reducing the number of mechanisms and maintenance personnel currently engaged in these jobs, by a factor of 2-3, increasing labor productivity by 15–20%, increasing the full wood coefficient of the beams and increasing their strength characteristics due to improved quality rafting and forming works.
