(54) DEVICE FOR LIFTING A LESOMATERIAL

The invention relates to lifting equipment, namely, devices for lifting timber.

A device for lifting is known. timber, including the receiving chute with stoppers, becoming and feeding mechanism 1.

The disadvantage of the device is the cumbersome design.

A device for lifting timber is known, including a receiving choke with hinged stoppers, a tubular stand and a feed mechanism 2.

The disadvantage of this device is the low feed rate of the timber,

The purpose of the present invention is to increase the feed rate of timber.

This goal is achieved by the fact that the feed mechanism is made in the form of blocks with spring-loaded sector grippers and movement jacks, with folding stoppers provided with spring-loaded push rods, and the chute is swivel guides and stops, interacting with sector grippers,:.

FIG. I shows the device, VIEW side; in fig. 2 - the same plan view; in fig. 3 shows section A-A in FIG. one,

The device includes an accepter. Gutter I, mounted on frame 2, on which also yKpeiiJteHbi displacement jacks 3 and spacing posts 4. The chute is equipped at its ends with folding stoppers 5 and 6c subselected. pushers 7 and 8, on which stems spring 9 are mounted, in the area between folding stoppers 5 and 6 spring-loaded guides 1О and 11 with clamps 12 and 13 are installed on the groove, and stops 14 and 15 are installed on the side surface at the beginning of the longitudinal opening At the ends of the jack in the jack, a balanced rocker 16 is strengthened, at one end of which a balance mechanism 17 is installed, and the other end is equipped with spring-loaded sector grippers 18 and 19. with

20 and 21 return rifles. Kupisa with spring-loaded grippers and a jack and movement form a coping mechanism. On each of the sections of the screen there are protrusions 22 and 23 in contact with the respective directional directors. To the upper end of the rail is fastened by becoming 24 of the pipe sections, about which the timber 25 is delivered to the required point of production. The pipes are interconnected with quick-release locks 26. Dp of operation control of the device on the frame and chute are installed blocks of control of jacks and pushers. The entire control system provides for the use of standard equipment and, therefore, on graphic material, in order to avoid darkening of the basic elements, is not shown.

The device works as follows.

The working medium is delivered to the jacks 3 through the elution unit with the spool box, which results in a continuous operation of the jack when they are loaded. The blocking motion in the gateway is 16 s, the sector grippers 18 and 19. The timber 25 is fed into the groove 1 below the bottom face the hole; and, falling between the pie grippers 18 and 19, moves upwards. At that moment, when the sectoral grapples make a return movement, the timber is held in the chute by the lower flap 6. After moving the next timber up it is yoPY In the working zone of the upper flap 5. IF the length of the timber is shorter than the distance between the flap stoppers 5 and 6, then The work to hold the timber is performed by one of the stoppers, and if the length is longer than the distance, then there is an obastator in the work. The initial capture of wood by sector grippers 18 and 19 is carried out due to the efforts of springs 2O and 21 by unwinding them. When the plant is operating in the mode of lifting timber, the working medium is not supplied to the piston cavities of the pushers 7 and 8, and due to the effort the spring is set in the rod cavity .9. The preliminary gripping of the timber is stopped. In the lifting mode, the guides Yu and 11 are not involved in the work and are located in a complex693O36

NOM position due to the clamps 12 and 13.

The balancing of the scenes during reciprocating movements is carried out by means of a balancing mechanism 17 with respect to the frame 2 and the groove 1 ..,

In case of need unloading tubular stav 24 from timber

The device has a descent mode. In this case, the fixing is removed from the guides 10 and 11, and they take up the working position due to the springs, as indicated by the arrows in FIG. 3

The operation of the plant in the descent mode is carried out as follows. With the slides fully extended, the pie grippers 18 and 19 with the stops 14 and 15 are pulled out of the trough cavity and during this time

 guides 10 and 11 are thrown over the protrusions 22 and 23 of the sector fuses. When moving the scenes 16 upward, the grippers move away from stops 14 and 15 and, under the action of springs 2O p 21, enter the cavity of chute 1, but meet on their hyr-H directions 10 and 11 and protrusions 22 and 23 slide along the direction upwards , not in contact with: the material located in the chute, which is held by the folding stools 5 and 6. When the kulvsy 16 approaches the extreme upper position, vyteupa 22, and 23 jump off from the guides (shorter than the stroke length of the shtosh of jacks 3) and sector ones The grippers come into contact with the timber. At this moment, the control system delivers the working environment to the porcine cavities tol, Q cathels 7: and 8, which take the folding stoppers 5 and 6 away from the forest and immediately (the movement of the coupons 16 starts down, and the sectoral pick-up pushes the wood down to the forest). stroke of the cylinder rod 3. tyudhod the link to the lowest position, the supply of the working medium into the pusher cavities of the pusher stops and the folding stoppers 5 and 6 under the Action of the springs 9 are in contact with the timber and fix it in the occupied position, and the link 16 brings the sectors e clamps to stops 14 and 15 and they occupy a starting position for

5 next cycle.

The fixture of the device in the excavation is carried out with the help of spacer racks 4. The construction of the device for lifting timber by rising Bbipa6of cam allows it to be installed at any point of the rising excavation. So, for example, when delivering timber to the lava of a coal seam with the development of its ledges (hammer), the feed mechanism of the first device is installed on the lava conpswcetma with a drift and at the same time absolutely clutters the drift and impedes traffic. The rest can be installed in the lower part of the ledge that is about; the furnace prdg "m a dwarf pa along the entire length of the lava, working out the combine harvester, feeding the logging agent; and and the pipe becoming gradually increases and provides the feed of the plow mater to any point of the line up to the valve. tsoyogo drift. The use of the described device will reduce the laboriousness of manual work, improve the safety of work, and accelerate the supply of timber. Formula of the Invention A device for accessing timber, including a receiving chute with hinged stoppers, a tubular stand and a feed mechanism, which is provided with The fact that, from the speed of yielding, filed timber, the feeder is v1 "Oly in the form of cupies with spring-loaded sector grippers; atami and jack, displacement, tfichyh folding ciotR} spring-loaded FolMtegaty, and the housing section is self-folding, and it is spring loaded; uyu | ymi, yoaimodeist vuyshimi: q bektoryygm captures.
