Description

Technical Field

[0001] The utility model belongs to the technical field of transportation, and in particular relates to a rail steel precision lifting truss vehicle. Background Art

[0002] At present, I-beams or rail steels are mainly hoisted by wire ropes. Although wire rope hoisting can achieve the purpose of transporting I-beams, due to the long length, heavy weight, and variety of models of I-beams or rail steels, the flexible connection between the wire rope and the steel requires manual participation throughout the hoisting process to stabilize the I-beams or rail steels to prevent violent shaking. In addition, the relative position of the wire rope on the I-beam or rail steel needs to be manually fixed before each hoisting, and the operation steps are relatively cumbersome. It can be seen that the use of wire ropes to hoist I-beams or rail steels has a low degree of automation in the entire process, there are safety hazards, and it affects the transportation efficiency of I-beams or rail steels.

[0003] The Chinese utility model patent with application number 201920691158.6 discloses an I-beam lifting device, which includes a top frame and multiple groups of lifting mechanisms arranged at intervals in the length direction of the top frame; each lifting mechanism includes a mounting frame and a pair of relatively arranged clamp units, each clamp unit includes a fixed frame, a drive assembly and a clamp assembly, the drive assembly is arranged on the fixed frame, the drive assembly includes a drive shaft, and the drive shaft can be retracted in a straight line in the vertical direction; the clamp assembly includes a guide rod, two connecting rods and two clamps; the drive shaft retracts or extends in a straight line in the vertical direction to drive the guide rod to move in the vertical direction to rotate the two connecting rods, so that the two clamps move closer or farther from each other to clamp or release the wing plate of the I-beam. When transporting the I-beam, the lifting device does not need to use a steel wire rope to flexibly connect the I-beam, the I-beam will not shake during the transportation process, and no manual stabilization is required. The transportation operation is simple and feasible, and the overall degree of automation is high. The disadvantage is that each clamping position requires four-point alignment. If one point is not aligned or clamped, it will cause safety hazards in the lifting process, which needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide a rail steel precise lifting truss car, which overcomes the shortcomings of the prior art and adopts a claw-type clamping structure. Each clamping position only requires a pair of claws. The claws are driven by the oil cylinder to move from the release position to the clamping position. The movement amplitude is small and the response is rapid. A rail steel can be lifted and transported by clamping it at the front and rear positions. The clamping acts on the wing plate of the rail steel. The positioning accuracy is low and the clamping effect is stable, which avoids the unhooking phenomenon caused by shaking or collision during the lifting process.

[0005] To achieve the above purpose, the utility model is implemented through the following technical solutions:

The sleeve is arranged under the support plate. The sleeve is connected to the industrial chain and the piston rod end of the lifting cylinder in turn. A semicircular sprocket is provided at the bottom of the industrial chain on the side connected to the sleeve to rotate the industrial chain 90°.

[0008] The industrial chain is provided with a plurality of branches, and the number of the branches is consistent with the number of the rotating claw rods.

The support track and the driving rack are arranged in parallel on two cantilever beams. The synchronous shaft is connected to the main beam through a bearing seat. Two driving gears and two guide support wheels are arranged on the synchronous shaft. The driving gear is meshed with the driving rack, and the guide support wheel rolls along the support track to ensure that the driving gear is correctly meshed with the driving rack.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1) In the length direction of a rail steel, more than two pairs of swivel claw clamping structures are used. Each clamping position only requires one pair of swivel claws. Driven by the oil cylinder, the swivel claws move from the release position to the clamping position to complete the clamping action. The movement amplitude is small and the response is fast. After a rail steel is clamped at the front and rear positions, it can be lifted and transported. Because the clamping acts on the wing plate of the rail steel, the positioning accuracy requirement is low and the clamping effect is stable, which effectively avoids the unhooking phenomenon caused by shaking or collision during the lifting process.

[0015] 2) The device of the utility model can be used for the transfer of rails or channel steels between the rollers of the production line and the conveyor rollers. It can move to the steel under remote control and clamp it with a rotating claw. Compared with the transfer by binding with wire ropes, the degree of automation is greatly improved, the labor intensity is greatly reduced, the production efficiency is improved, the rail steel transfer posture is unified, and the stacking is more compact and regular.
