Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a step-by-step approach bridge lifting mechanism for self-moving trestles, through which a step-by-step approach bridge lifting mechanism for self-moving trestles solves the problem that in traditional trestle designs, oil cylinders are usually used to lift it , but this kind of structural design is often easy to cause hard damage (structural damage) to the lifting cylinder, and the expansion and contraction space of the cylinder structure is limited, resulting in the inability to continue part of the construction, resulting in the problem of low work efficiency

Embodiment Construction

[0014] Below in conjunction with accompanying drawing and specific embodiment the invention is further introduced:

[0015] Such as figure 1 As shown, a step-by-step self-moving approach bridge hoisting mechanism includes an approach bridge 3, a main bridge body support hanger 1 and an electric hoist 2, and the electric hoist 2 has a hook connected to the same side of the approach bridge 3 with hoisting pull buckles; The electric hoist 2 hook is connected with the main bridge body with the side support hanger 1.

[0016] The number of further electric hoists 2 is 4, and two are respectively installed on the front approach bridge and the rear approach bridge. In the operating space, since each approach bridge has two left and right approach bridges, an electric hoist is installed on each of the left and right approach bridges, which is convenient for lifting; the wire rope electric hoist is small in size and easy to disassemble.

[0017] The further main bridge body supports ...

Abstract

The invention discloses an approach bridge lifting mechanism of a stepping type automatically moving trestle, comprising an approach bridge, main bridge body supports and hangers and electric hoists, wherein lifting hooks of the electric hoists are connected with lifting buckles at the same side of the approach bridge; and hooks of the electric hoists are connected with the supports and hangers at the same side of a main bridge body. The approach bridge lifting mechanism disclosed by the invention solves the problems that in the traditional trestle design, an oil cylinder is usually adopted for lifting the trestle, hard damage (structural damage) is often easily caused to the lifting oil cylinder by the structural design, and the telescopic space of the oil cylinder structure is limited, so that partial construction can not be continued, and the working efficiency is low.

Description

technical field [0001] The invention relates to a hoisting mechanism for an approach bridge, in particular to an approach hoisting mechanism for a step-by-step self-moving trestle, which belongs to the field of construction engineering. Background technique [0002] The approach bridge is the connection part between the trestle bridge and the ground, and is used as the upper and lower trestle bridges for engineering equipment. The approach bridge is divided into left and right parts, and the middle part is integrally connected and lifted by section steel. In the traditional trestle design, oil cylinders are usually used to lift it, but this kind of structural design is often easy to cause hard damage (structural damage) to the lifting oil cylinder, and the expansion and contraction space of the oil cylinder structure is limited, which makes it impossible to continue part of the construction. Work efficiency is low. Contents of the invention [0003] The technical problem...
