Description

Technical Field

[0001] The present invention relates to the technical field of underground construction transportation, and in particular to a rail-type transfer platform for transporting materials for underground construction and an implementation method thereof. Background Art

[0002] The rail transfer platform for material transportation for underground construction is a material transportation equipment designed specifically for underground projects. It adopts a rail-type operation mode and can flexibly shuttle in narrow and low underground spaces to achieve efficient and rapid material transportation. The platform is usually equipped with a powerful power system, a stable load-bearing structure and an advanced control system. It can carry and transport various construction materials, equipment and waste, etc. Its advantages are stable operation, safety and reliability, high transfer efficiency, and can effectively reduce labor costs and time costs. It is an indispensable and important tool in underground construction.

[0003] A Chinese patent with publication number CN113060565A discloses a rail-type transfer platform for conveying construction materials, including a handle, one end of which is fixedly connected to a buckle, and an outer surface of the handle is fixedly sleeved with a driving wheel, and a moving mechanism includes a first screw rod. By pushing the handle, the buckle is engaged with a slot on the first screw rod, and then the handle is rotated to drive the first screw rod to rotate, and the lifting plate is driven up and down by structures such as a nut sleeve and a movable rod. The movable wheel can be stored, so that the device can be quickly switched between movement and stable fixation, thereby improving the flexibility of the device and facilitating use by staff.

[0004] When the construction material conveying rail transfer platform of the above-mentioned patent is fixed, it is necessary to adjust the longitudinal horizontal position of the movable wheel by rotating the handle. However, after storing items, the storage hopper is heavy and it is not convenient to adjust the longitudinal horizontal position of the movable wheel by rotating the handle. It is difficult to rotate the handle by manpower. Summary of the invention

[0005] The object of the present invention is to provide a rail-type transfer platform for material transportation for underground construction and an implementation method thereof. By clamping the transmission shaft through a pair of clamping plates and at the same time by a limiting bar fitting one end of the roller, the rotation of the transmission shaft and the roller can be fully restricted, and the rotatable roller can be stably locked and stopped from rotating. The restriction of the roller can be ignored and the restriction of the roller can be stably performed over a large range, so that when the transfer platform carries heavy weight materials, there will be no position deviation, and it can be stably stopped at the required position, and it will not be difficult to lock the roller due to the heavy material, thereby solving the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a rail-type transfer platform for transporting materials for underground construction, comprising a pallet, a storage hopper is arranged at the upper end of the pallet, a pallet is arranged in the middle of the lower end of the storage hopper, a base is arranged at the lower end of the pallet, transmission shafts are arranged on both sides of the lower end of the base, clamping plates are arranged on both sides of the two transmission shafts, and a limiting strip is arranged laterally at the front end of the base.

[0007] Preferably, second transmission rods are welded on both sides between the base and the tray, and two of the second transmission rods respectively penetrate a pair of clamping plates and are threadedly matched with the penetration positions of the clamping plates, and the second transmission rods are bidirectional threaded rods.

[0008] Preferably, a first transmission rod is provided through the upper end of the limiting strip, the outer portion of the first transmission rod is threadedly engaged with the penetration position of the limiting strip, a limiting frame is provided outside the limiting strip, and the inner portion of the limiting frame is slidably connected to the outer portion of the limiting strip.

[0009] Preferably, second bevel gears are arranged around two adjacent welding positions of the second transmission rods, a first bevel gear meshingly connected is arranged on the side of the first transmission rod facing the outside of the second bevel gears, and the first bevel gear is welded and fixed to the first transmission rod.

[0010] Preferably, a transmission disc is welded to one end of the first transmission rod facing the limiting bar.

[0011] Preferably, first connecting blocks are welded at both front and rear ends of both sides of the pallet, grab hooks are provided at the rear end of one side and the front end of the other side of the pallet, and the grab hooks are located inside the first connecting block, and the grab hooks are rotatably connected to the outside of the first connecting block.

[0012] Preferably, the outside of the grab hook is connected to the internal slot of the first connecting block.

[0013] Preferably, shock-absorbing blocks are provided at middle positions on both sides of the tray, and the shock-absorbing blocks are fixedly connected to the tray by bolts.

[0014] A method for implementing a rail-type transfer platform for transporting materials for underground construction comprises the following steps: Step 1: dump the material and place it inside the storage hopper. The grab hook in one of the transfer platforms is rotated and embedded into the first connecting block in another adjacent transfer platform. The rotation of the roller can make the transfer platform move horizontally. Step 2: The grab hook pulls the first connecting block, and when the front transfer platform decelerates, the shock-absorbing block buffers the force generated by the collision; Step 3: The connected transfer platforms are stopped from moving in turn by the buffering of the shock-absorbing block, and the rotation of the transmission plate drives the first bevel gear to rotate through the first transmission rod; Step 4: The rotation of the first bevel gear drives the second transmission rod to rotate through the second bevel gear, and the thread on the outer wall of the first transmission rod cooperates with the internal thread of the limiting bar, and the limiting bar is restricted by the limiting frame so that the limiting bar moves laterally toward the roller; Step 5: The rotation of the second transmission rod generates relative motion with the inside of the two pairs of clamping pieces respectively. The clamping pieces move laterally relative to each other after being restricted by the base and clamp the transmission shaft. The lateral movement of the restriction bar will be close to the roller. Step 6: The extension and retraction of the hydraulic telescopic rod pushes the second connecting block inside the sliding rail, and the storage hopper rotates in the bracket, and the material inside is directly dumped by the rotation of the storage hopper.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. When fixing the transfer platform after the movement, the present invention only needs to rotate the transmission disk to fix the roller, wherein the rotation of the transmission disk can drive the second transmission rod to rotate after the transmission of the first bevel gear and the second bevel gear, and the rotation of the second transmission rod can make a pair of clamping pieces move relatively and clamp the transmission shaft, and in addition, the rotation of the transmission disk can drive the restriction bar restricted by the restriction frame to move laterally toward the roller, and the restriction bar will contact the roller and squeeze the roller, and the restriction is used to squeeze the roller while transmitting the transmission shaft, and there is no need to adjust the longitudinal horizontal position of the roller while fixing the roller, and when fixing the roller, the weight of the items placed in the storage hopper can be ignored, which is convenient for users to use.

[0016] 2. When two adjacent transfer platforms are combined, the grab hook inside the transfer platform pallet of the present invention can be rotated and embedded in the first connecting block position inside the adjacent transfer platform pallet, and the connection method is convenient. On the other hand, when multiple transfer platforms connected end to end are moved, the shock-absorbing blocks between the two adjacent transfer platforms will fit together to avoid collisions that cause loud noise and shaking, so that the transfer platform can be transported stably during transportation. At the same time, the two shock-absorbing blocks fit together to protect the transfer platform, increase the service life of the transfer platform, and avoid damage to the transfer platform due to continuous collisions.
