[ detailed description ] embodiments
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
The utility model discloses a combine and adopt hydraulic support from moving lower plate wagon device, including platform, connecting piece and two chains 10 of unloading. The unloading platform leans against the unloading end of the plate trailer 9, the connecting piece is connected to the pushing head of the hydraulic support 8, the two chains 10 are respectively connected to the two ends of the hydraulic support 8, the length of each chain 10 is slightly larger than the length of the bottom plate of the hydraulic support 8, the length of the plate trailer is 4.5-4.8 m generally, the chains 10 are iron chains and have certain weight, the iron chains are difficult to straighten manually, and the chain length is 5.5m in the middle of the plate trailer due to the fact that the chains are longer than the plate trailer. Thereby, the hydraulic support 8 and the platform are connected through the chain 10, when the pushing head of the hydraulic support 8 pushes, the hydraulic support 8 will move relative to the plate trailer 9 due to the action of the chain 10 and the platform, and finally move to the inclined plane 7 of the platform.
As shown in fig. 4, the vertical section of the platform is a right trapezoid having an inclined surface 7, a vertical surface and two side surfaces. The height of the trapezoid is equal to the height of the pallet 9, so that the vertical face of the unloading platform can be attached to the unloading end of the pallet 9, so that the hydraulic support 8 moves from the unloading end of the pallet 9 to the inclined surface 7, and the high end of the inclined surface 7 is close to the unloading end of the pallet 9. After the hydraulic support 8 is moved to the inclined surface 7, the unloading platform needs to be taken out, so that the length of the inclined surface 7 is smaller than that of the base of the hydraulic support 8, the hydraulic support 8 is prevented from completely staying on the inclined surface 7, and the unloading platform is difficult to take out. Two side surfaces of the unloading platform are respectively provided with a plurality of hook holes 6 for hanging hooks at the rear end of the chain 10.
As shown in fig. 1, 2 and 3, the lower part of the connecting piece is provided with two lug plates 4 for detachable connection with the pushing head of the hydraulic support 8, the upper part is provided with a U-shaped clamping groove 2, the height of the U-shaped opening of the clamping groove 2 is consistent with the thickness of the chain 10 and is smaller than the height of the chain, so the chain 10 can transversely pass through the U-shaped opening, the chain 10 is composed of a plurality of iron rings, two adjacent iron rings can be used for ensuring that one of the two iron rings is transverse and vertical, after the two iron rings pass through the U-shaped opening, the iron rings in the U-shaped opening are transversely arranged, two iron rings adjacent to the transverse iron ring are vertical, and when the chain is stressed, the vertical iron rings are clamped outside the U-shaped opening, so that the clamping connection of the chain 10 and the clamping groove 2 is realized.
The U-shaped opening of draw-in groove 2 is towards the non-end of unloading of wooden handcart 9, and the equal fixedly connected with roof 1 and bottom plate 3 of the last lower extreme of draw-in groove 2, and roof 1 and bottom plate 3 are dull and stereotyped, and the lower extreme of draw-in groove 2 is connected to the upper end of roof 3, and two otic placodes 4 are connected to the lower extreme of roof 3. Because hydraulic support usually weighs several tons even tens of tons, so will guarantee the fastness of whole device, so the upper and lower terminal surface of draw-in groove 2 needs the reinforcement, and this reinforcement function can be realized to roof 1 and bottom plate 3.
Two chains 10, the one end of every chain 10 all is connected on platform 5 of unloading, and the equal joint of the other end is on draw-in groove 2, and two chains 10 are located the both sides of hydraulic support 8 respectively. The front end of each chain 10 is bound on the clamping groove 2, the rear end of each chain is provided with a hook, and each hook is hung in the hook hole 6.
The utility model discloses the self-moving plate trailer device that descends designs simply, convenient operation, and the cost of manufacture is low, utilizes hydraulic pressure characteristic ability to make the steady plate trailer down of hydraulic support, does not destroy when guaranteeing that coal hydraulic support gets off and strut, does not damage equipment, has guaranteed the personnel's safety of installer when the support gets off the vehicle.
The utility model discloses a working process does:
the plate trailer 9 provided with the hydraulic support 8 is pulled to the getting-off position, the plate trailer 9 is well connected with the loading platform, and the plate trailer provided with the hydraulic support is fixed firmly to prevent sliding. The liquid is fed into a hydraulic support 8 arranged on a plate trailer 9 for supplying liquid (the liquid return can be omitted, the liquid return can directly flow out, if the requirement is met on the mine, the liquid return pipe is also connected), and whether the support is normal is tested. Connecting the connector with a pushing head of a hydraulic support 8 on a plate trailer 9, and respectively hanging iron hooks of a chain 10 in hook holes at two sides of a loading platform; and finally, respectively installing a high-strength circular ring chain behind the iron hook to be clamped at the chain clamping position on the connecting head, wherein the state of the hydraulic support is as shown in figure 5.
Operating a pushing handle of the hydraulic support 8 to push and extend the hydraulic support; when the pushing cylinder stretches out, the getting-off device pushes against the pushing, the hydraulic support 8 is forced to move backwards, and the pushing cylinder is recovered and pushed after the pushing cylinder stretches out; the hydraulic support in the middle process is in a state shown in fig. 6, the round-link chain is clamped on the connecting head again, the pushing handle of the hydraulic support 8 is continuously operated, the hydraulic support is retreated to the loading platform behind the plate trailer for 3-4 times of repeated operation, and the plate trailer loading task of the hydraulic support is completed as shown in fig. 7.
