Problems solved by technology

[0007] Risks in the construction process: ① The center of gravity of the pin shaft is adopted at a single point. Due to the smooth surface of the pin shaft, it is easy to cause the pin shaft to slip; The ram and hoisting machinery have high requirements for mutual cooperation; ③Before the pin shaft enters the pin shaft hole, the concentricity between the shaft and the shaft hole is extremely demanding. Adjusting by the truck crane not only wastes manpower and material resources, but also very likely causes the surface of the pin shaft to be damaged. damage
[0008] The traditional construction process is complicated, the special equipment takes a long time and requires high coordination operation, which is time-consuming, laborious and costly

Embodiment Construction

[0038] The following examples can enable those skilled in the art to understand the present invention more comprehensively, but the present invention is not limited to the scope of the described examples.

[0039] Such as Figure 1-Figure 9 An adjustable pin-mounted platform is shown, including

[0040] A working base, the working base includes a standing platform 1 and a mounting bracket 2 arranged on the standing platform, the standing platform 1 is a cuboid structure, and the two sides of the upper end surface of the standing platform 1 are fence structures for operators to stand on, The mounting bracket 2 is a rectangular parallelepiped frame structure fixed on the standing platform 1, and a through groove 3 is provided on the standing platform 1 directly below the mounting bracket 2 simultaneously.

[0041] A forklift positioning seat 4 is arranged at four corners of the bottom end of the stand platform 1, and a through hole 5 for inserting a forklift arm is arranged in ...

Abstract

The invention relates to an adjustable pin shaft installation platform which comprises a work base, a pin shaft supporting assembly and a push assembly. The work base comprises a standing platform andan installation support arranged on the standing platform. The pin shaft supporting assembly is arranged on the installation support and comprises at least one pin shaft supporting base installed onthe installation support, the pin shaft supporting base is provided with a V-shaped groove for containing a pin shaft, the push assembly is arranged on the side of the pin shaft supporting base and comprises a push part located on one side of the V-shaped groove of the pin shaft supporting base, and the front end of the push part is opposite to the V-shaped groove. The adjustable pin shaft installation platform has the advantages that by means of the cooperation of the work base, the pin shaft supporting assembly and the push assembly, the pin shaft is supported and pushed, therefore, the platform only needs to be matched with a forklift or other similar lifting mechanisms to lift a whole platform to the installation position of the pin shaft, great convenience is brought, the number of staff needed by installation is greatly reduced, assembling is fast, operation is easy, practicability is high, and safe risk is low.

Description

technical field [0001] The invention relates to the field of assembly of large cranes, in particular to an adjustable pin shaft installation platform. Background technique [0002] The pin connection form is a common structural form of large cranes, and it is mostly used in the pulley structure. Pulley pins are usually divided into the following forms: ① single pulley structure; ② pulley block structure. Affected by factors such as installation and operation space and high requirements for fit clearance, the installation process of the pin shaft in the pulley block structure is extremely difficult. [0003] The traditional pulley pin installation construction process is roughly as follows: [0004] Coordinated equipment: 2 truck cranes, 1 climbing car, scaffolding platform. [0005] Construction period and construction manpower: Taking the single-axis installation of the auxiliary hook pulley of the crane jib as an example, 8 people are required to cooperate in the constr...
