Abstract

The utility model discloses an auxiliary device for a tower arm amplitude-variable fixed pulley rope threading, which comprises a front stay bar A and a front stay bar B, wherein a pulley block is arranged at one end of the front stay bar A, guide wheels are arranged at two ends of the pulley block, and a slideway is arranged at the top of one end of the front stay bar B. Through the use of the directional wheel and the slideway, the directional wheel can fall on the slideway after the pulley block naturally hangs down, thereby ensuring that a small swing angle exists on the pulley block, keeping a certain distance between the pulley block and the front supporting rod B and ensuring the space when the steel wire rope is connected in a penetrating way.

Description

Auxiliary device for tower arm amplitude-variable fixed pulley rope threading

Technical Field

The utility model relates to the technical field of crawler cranes, in particular to an auxiliary device for a tower arm amplitude-variable fixed pulley rope threading.

Background

In the transportation process of the tower arm component of the crawler crane, the tower arm component sleeve is generally transported and installed integrally because of complex assembly relation, the uppermost supporting rod structure is a tower arm rear supporting rod, and the upper section of the tower arm rear supporting rod is connected with a tower arm amplitude-changing fixed pulley block. After the steel wire rope of the pulley block is removed, the pulley block can naturally sag downwards due to the dead weight of the pulley block without constraint, and collide with other parts in the transportation process. In addition, the whole pulley block is heavy in weight, and after the pulley block naturally hangs down, when the pulley block is threaded to adjust the amplitude variation multiplying power of the tower arm, the space is very narrow.

Disclosure of Invention

The utility model aims to provide an auxiliary device for a tower arm amplitude-changing fixed pulley rope threading so as to solve the problems in the background art.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the auxiliary device for the tower arm amplitude-variable fixed pulley rope threading comprises a front stay bar A and a front stay bar B, wherein a pulley block is arranged at one end of the front stay bar A, guide wheels are arranged at two ends of the pulley block, and a slideway is arranged at the top of one end of the front stay bar B.

Preferably, the bottom of the guide wheel is lower than the plane of the bottom of the pulley block.

Preferably, the number of the guide wheels is two.

Preferably, two sliding grooves are formed in the top of the sliding way, and the two sliding grooves are arranged corresponding to the two guide wheels.

Preferably, the front stay bar a and the front stay bar B are arranged vertically correspondingly.

Compared with the prior art, the utility model has the beneficial effects that:

the auxiliary device for the tower arm amplitude-variable fixed pulley rope threading is characterized in that the directional wheel and the slideway are used, so that the directional wheel can fall on the slideway after the pulley block naturally hangs down, a small swing angle of the pulley block is ensured, the pulley block and the front supporting rod B are kept at a certain distance, and the space for threading the steel wire rope is ensured.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a top view of the slide of the present utility model.

In the figure: the front stay bar A is 1, the pulley block is 2, the guide wheel is 3, the front stay bar B is 4, and the slideway is 5.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, the present utility model provides a technical solution: the utility model provides an auxiliary device for tower arm becomes width of cloth fixed pulley and wears to be rope, including preceding vaulting pole A1 and preceding vaulting pole B4, preceding vaulting pole A1 and preceding vaulting pole B4 are corresponding the setting from top to bottom, pulley block 2 is installed to preceding vaulting pole A1's 1 one end, leading wheel 3 is all installed at pulley block 2's both ends, the quantity of leading wheel 3 is two, the bottom of leading wheel 3 is less than the plane of pulley block 2 bottom, slide 5 is installed at the top of preceding vaulting pole B4 one end, two spouts have been seted up at the top of slide 5, and two spouts are corresponding the setting with two leading wheels 3.

Working principle: after the front stay bar A1 hangs down, the directional wheel 3 on the pulley block 2 can fall on the slideway 5 of the front stay bar B4, thereby ensuring that a small swing angle exists on the pulley block 2, ensuring that the pulley block 2 keeps a certain distance with the front stay bar B4 and ensuring the space when the steel wire rope is connected in a penetrating way.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
