Description

Technical Field

[0001] The embodiment of the utility model belongs to the technical field of T-beam transportation devices, and more specifically, relates to a beam transportation and shock absorbing device for a prefabricated T-beam moving pedestal. Background Art

[0002] In recent years, with the great investment in the construction of national highways, more and more highway bridges have been built. Prefabricated T-beams are an important component of bridges and are widely used. Prefabricated beams are usually composed of flange plates, web plates, and diaphragms. After the beam body is cast and the formwork is removed, the flange plates and diaphragms are suspended. Supports must be set at the bottom of the flange plates and the bottom of the diaphragms to prevent cracks from forming on the prefabricated beam diaphragms themselves or between the diaphragms and the flange plates and web plates. In the prefabrication of T-beams, in order to realize the production line operation of beam pieces, a pedestal that can carry the T-beam is designed to move together.

[0003] The top of the mobile pedestal is equipped with a support structure to support the T-beam. At present, many projects use square wood or rigid jacking, but the disadvantage of these support methods is that they cannot fit tightly with the wing plate and have no jacking force. Over time or when encountering slight bumps, the diagonal brace will leave the beam body, which will not achieve a stable support effect and will damage the beam body, affecting the safety and quality of construction.

[0004] Therefore, at this stage, there is an urgent need for a beam transport shock-absorbing device that can stably support beams of different heights during T-beam transportation without damaging the beams. Summary of the invention

[0005] In view of the problems that the supporting structure of the prior art cannot fit tightly with the wing plate, cannot achieve a stable supporting effect, and will damage the beam body, affecting the safety and quality of construction, the utility model provides a beam transport and shock-absorbing device for a prefabricated T-beam moving pedestal to solve such problems.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a beam transport and shock-absorbing device for a prefabricated T-beam moving platform, comprising: a base fixedly arranged on the top of the moving platform; a height adjustment mechanism arranged on the top of the base, which adjusts the height of the support plate through the guide mechanisms on both sides; a first buffer component for buffering the impact force in the vertical direction, comprising a damping rod vertically fixedly arranged on the top of the support plate, and a square plate fixedly arranged on the top of the damping rod; a second buffer component for buffering the impact force in the horizontal direction, comprising a square rod parallel to the top of the square plate, a support seat slidably arranged on the square rod, and a second spring sleeved on the square rod and resisting both ends of the support seat; and a top plate fixedly arranged at the bottom of the T-beam, the bottom of which is hinged to the top of the support seat.

[0008] Furthermore, the other ends of the two groups of inclined rods fixedly connected to each other are hinged to the bottom of the top plate through a hinge seat.

[0009] Furthermore, the second buffer assembly also includes vertical plates symmetrically arranged at two ends of the top of the square plate, and the inner sides of the vertical plates are fixedly connected to the ends of the square rods.

[0010] Furthermore, the height adjustment mechanism includes a sleeve whose bottom is rotatably arranged on the top of the base, and an adjusting stud threadedly connected to the sleeve. By rotating the sleeve, the adjusting stud is raised or lowered, and the height of the support plate fixed on the top of the adjusting stud is adjusted.

[0011] Furthermore, a first gear is fixedly provided on the outer periphery of the sleeve and meshes with a second gear. The second gear is fixedly provided on the motor shaft of a servo motor. The servo motor is fixedly provided on the top of the base. The second gear meshes with the first gear and rotates through the drive of the servo motor, thereby causing the sleeve to rotate and adjusting the stud to rise or fall.

The locking mechanism includes a fixing plate fixed on the base, an electric push rod fixed on the fixing plate, and a locking plate provided at the front end of the electric push rod.
