Description

Technical Field

[0001] The utility model relates to the field of rapid displacement tooling for portal cranes, and more specifically, to a novel rapid displacement tooling for portal cranes. Background Technique

[0002] Due to the characteristics of heavy weight and high height of the portal crane itself, there are certain difficulties in the displacement and installation of the portal crane. Because of its large weight, it is difficult to hoist, and with a high center of gravity, its stability is poor. Therefore, generally, disassembly and reinstallation are adopted for displacement, and large lifting equipment is required, resulting in high costs, long cycles, and a large working area.

[0003] CN204162355U relates to a rapid displacement tooling for a portal crane, which includes a lifting and transporting flatbed truck, two middle crossbeams, two end crossbeams, two displacement supports, and a counterweight. The two middle crossbeams are arranged in parallel at intervals between the two end crossbeams, and all four crossbeams are supported on the lifting and transporting flatbed truck.

[0004] The lifting and transporting flatbed truck is lifted and translated. When the lifting and transporting flatbed truck supports large and small lifting equipment, its stability is not good. Moreover, a moving wheel for translation is arranged in the bottom moving seat of the portal crane main body, which is not convenient for driving and walking, inconvenient to use, and not convenient to detach during disassembly and replacement. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a novel rapid displacement tooling for a portal crane. The machine body is lifted and moved by directly driving the rollers to support the ground through a hydraulic cylinder. Through the support of the I-shaped beam for the lifting assembly, the stability is improved. Moreover, the moving seat at the lower end of the machine body is convenient for self-driving movement and walking, convenient to use, and convenient to detach during disassembly.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] The novel rapid displacement tooling for a portal crane includes a machine body and a moving seat. Support wheels and walking wheels are arranged in the moving seat. A top plate is extruded at the bottom of the machine body. An I-shaped beam is fixed to the lower surface of the top plate. A hydraulic cylinder is fixed to the lower surface of the I-shaped beam. A folding seat is fixed to the lower surface of the hydraulic cylinder. A wheel shaft is arranged in the first folding seat, and a roller is fixed to the outside of the wheel shaft. A worm gear is arranged outside the walking wheel, and a worm is arranged inside the moving seat. The machine body is lifted and moved by directly driving the rollers to support the ground through a hydraulic cylinder. Through the support of the I-shaped beam for the lifting assembly, the stability is improved. Moreover, the moving seat at the lower end of the machine body is convenient for self-driving movement and walking, convenient to use, and convenient to detach during disassembly.

[0008] Furthermore, a second folding seat is arranged on the side of the moving seat. A motor is fixed inside the second folding seat. A first bevel gear is fixed to the outside of the motor drive shaft, and a second bevel gear is fixed to the outside of the worm.

[0009] Further, the worm gear meshes with the worm.

[0010] Further, the first bevel gear meshes with the second bevel gear.

[0011] Further, the I-shaped beams are distributed at both ends of the top plate.

[0012] Further, the hydraulic cylinders are distributed at both ends of the I-shaped beams.

[0013] Further, the support wheels are evenly distributed on the inner surface of the moving seat.

[0014] Compared with the prior art, the advantages of the present utility model are as follows:

[0015] (1) The roller is directly driven by the hydraulic cylinder to support the ground and lift the body to move. Through the support of the I-shaped beam for the lifting assembly, the stability is improved. Moreover, the moving seat at the lower end of the body is convenient for self-driven movement and walking, easy to use, and easy to disassemble and separate. BRIEF DESCRIPTION OF THE DRAWINGS
