Description

(54) TRUCK CONVEYOR

For brevity, it refers to the transporting machines, namely to the trolley conveyor (pa: m vertically closed mud, and can be used to transport various goods in the workshops of engineering plants.

The vertical vertically carriage conveyor belt, containing intertwined bogies, upper and lower russes of the tracks and transfer sections at the ends of the conveyor, having drives for their vertical movement and drives;

one.

Four drives in the conveyor

leads to a complex control system and, as a result, to a lack of reliability of the conveyor. at the ends of the conveyor 2.

The well-known conveyor also has four controlled drives and, as a result, a complex electroautomatic system with interlocking. In addition, the kinematics of the conveyor does not allow for the automatic unloading of carriages at the end of their movement.

The aim of the invention is to simplify the control of the conveyor and the possibility of automatic unloading of the pipe. This is achieved by the fact that one end of the transfer sections is fixed on the base and hinged, and the other side adjacent to the tracks is provided with a clamp, and on the outer surface of the shpirpl of the hydraulic cylinder there is a rod pivotally connected to the clamp and having a stop connected to the hydraulic cylinder rod, interacting with the traverse pusher carts.

FIG. 1 is a schematic diagram of a carriage conveyor; in fig. 2 and 3 schemes of transfer sections.

The proposed conveyor consists of mutually mixed trolleys /, the upper rus of the tracks 2, the lower rus of the tracks 5 and the transfer sections 4 and 5.

The transfer section 4 contains a swinging section of the rail tracks 6. At one of the ends of the section, two harnesses 7 are hinged, and the second end thereof is connected to the rod P having a stop by means of the shaft 8

5 / O and two hinged fortified asterisks //. The rod 9 has the ability to move along the outer surface of the hinged hydraulic cylinder 12, the shafts of which are rigidly connected with two chains 13, sprockets And and two stars 14, spanning

Zhespko zauraplennye on the shaft 8. On the same shaft 8 Zhespko fixed two more stars, covered by two chains of 16, connected between the two-traverse beam and the

17, interacting with carts / conveyor.

For precise joining of rail loops 6 of the transfer section 4 with the upper 2 and lower 3 channels of the conveyor.

18, a ball mounted on hall 8 and the interim simulator with a manhole 19 and with a pusher bar 17.

The transmission section 5 is similar in construction to the above and differs only in that the fiSat 18 interacts with the cart / conveyor through the lever system 20.

For automatic control of the conveyor cycle, there are end plugs 21 and 22, a valve spool 23 and support valves 24 and 25.

The conveyor is operated as follows.

When the limit switch 21 is triggered, the transfer section 4 is docked with the upper one (M blue of paths 2, and transfer section 5 - with the BOTTOM of 1 path 3). The working medium is fed into the cylinder cavity of the hydrodyliidra 12 of section 5. The supporting valve 25 lances the working medium only when pressure rises. Therefore, the idle stroke of the hydraulic cylinder 12 of section 5 is first performed. The rod of the hydraulic cylinder 12 moves the chains 13, rotates 31 //, 14, /, and 7 stars and the traverse-pusher 17 idles back. At the end of idling the traverse pusher 17 LidrocylIdra 12 rests on the ynoip 10 of the rod 5 and, with a further stroke of the rod, section 5 idles upwards.

At the end of idling, the latch 18 falls into the groove 19 and the transfer section 5 stops in the docked position with the upper light-brown path 2. The working pressure in the hydraulic system rises, the supporting clalan 25 opens, and the working medium enters IB the rod end of the hydraulic cylinder 12 of section 4. The rod moves targets 13, sprockets 11, 14, / 5 and 7 of the transfer section 4 rotate and chains 16 are moved from the grass) to the pusherlbm 17. When moving, the traverse pusher pushes the conveyor carts 1 to the upper track of the track 2 by one rail. At the end of its movement, the crosscutter presses the locking lever 18. The latch EXIT from the groove 19 and the transfer section 4 is lowered and joined to the lower light path 3.

When moving the carts 1 along the upper floor of the tracks 2, the front carriage pushes onto the transfer section 5, at the end of which, pushing the lever of the lever system 20, removes the retainer 18 from the pas: 19, and since the cylinder cavity of the hydrocylindra 12 of this section is under pressure working

Wednesday, after removing the latch 18 from the groove, the rod of the hydraulic cylinder 12 continues its way and turns the transfer section 5 into the upper inclined position of the automatic unloading of the trolley 1. The load slides, releasing the trolley. In the extreme upper position, the transfer section 5 acts on the limit switch 22, which gives impetus to the switching of the distribution valve 23, after which the flow of the working medium is directed into the rod cavity of the hydraulic cylinder 12 of the transfer section and under the action of the working medium of the hydraulic cylinder 12, moves in reverse direction, rotates the transfer section to the lower position. At the same time, the cart continues to hold the latch 18 in the retracted position and it goes through the groove 19, touching it. After docking the transfer section 5 with the lower light path 3, further movement of the rod of the hydraulic cylinder 12 moves the chains 13, the asterisks //, 14, / 5, and 7 rotate and the traverse-pusher 17 of the transfer section pushes the cart / conveyor along the lower floor of the track one step. At the end of pushing the rod of the hydraulic cylinder reaches its extreme position, the pressure of the working medium rises, the supporting valve 24 opens and the working medium enters the cylinder cavity of the hydraulic cylinder 12 of the transfer section 4, moves the rod and the rod 9. The transfer section 4 rises to the position of the joint with the upper wheel paths 2. In this case, the latch 18 sinks into the groove 19 and the limit switch 2D, which switches the distribution valve 33, is activated, the cycle repeats.

Filling the transfer sections of the swinging type conveyor with hydraulic cylinders that both transfer the trolleys from one track to another and pushing the trucks along the gear helps to reduce the number of conveyor drives by half. Besides, the wiring of the hydraulic system of the opposite cavities of the hydraulic cylinders of the two transfer sections allows controlling be them as one. By reducing the number of drives and simplifying the automation of the conveyor, the reliability of the conveyor is improved, and the downtime of workers and equipment is reduced. The automatic unloading of the conveyor bogie due to the inclination of the transfer section at an angle allowing the load to slide from the bogie platform is provided by the kinematics of the conveyor itself, as a result of which there is no need to use elevators and maintenance personnel for this purpose.
