Description

Connecting shaft chest expander for maintaining thick grille

Technical Field

The utility model relates to the technical field of auxiliary tools for repairing coarse gratings, in particular to a connecting shaft chest expander for repairing coarse gratings.

Background

After the rotary coarse grid runs for a period of time, the rotary coarse grid needs to be overhauled, and the conditions of falling off of a connecting plate, breakage of a shaft collar and the like are frequently found in the overhauling process. When the coarse grille connecting plate falls off or the shaft collar breaks, the hanging strips and the hanging hooks are required to be bound on the rake teeth connecting shaft, the connecting shaft is also tensioned by a manual hoist through the hanging strips, then the position of the connecting plate is adjusted to be installed in place, three and four people are required to be matched, the working efficiency is low, and the labor consumption is high; in addition, the space at the connecting plate is narrow, no place is used for exerting force, the work period for maintaining one position is long, the difficulty is large, and the efficiency is low.

Disclosure of Invention

In view of the above, the utility model aims to provide the connecting shaft chest expander for maintaining the coarse grille, which has the advantages of simple structure, convenient operation and convenient construction, aiming at the defects of the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a thick connecting axle chest expander for grid maintenance, includes fixed plate and regulating plate be equipped with two connecting holes respectively on fixed plate and the regulating plate install guiding screw and adjusting screw in the corresponding connecting hole of fixed plate and regulating plate the below of fixed plate and regulating plate is equipped with the fixture block relatively be located on the guiding screw the both sides of fixed plate and regulating plate are installed the nut respectively and are fixed it be located on the adjusting screw the nut is installed respectively in both sides of fixed plate and the inboard of regulating plate be equipped with adjusting part on the outside adjusting screw of regulating plate.

According to the technical scheme, the fixing plate and the adjusting plate are used for limiting adjacent connecting shafts on the coarse grid, the fixing plate is fixed through nuts on two sides of the fixing plate, then the position of the adjusting plate is adjusted through rotating the adjusting assembly, so that the distance between the two connecting shafts is limited, and then the nuts on two sides of the adjusting plate are rotated to fix the connecting shafts, so that the connecting plates and the shaft rings can be replaced conveniently; in addition, the fixing plate and the adjusting plate are fixed by the nuts, so that the distance between the fixing plate and the adjusting plate can be adjusted at will, and the limiting of connecting shafts with different widths can be realized.

Preferably, the adjusting assembly comprises a nut sleeve in threaded connection with the adjusting screw and a rotary table fixedly arranged outside the nut sleeve. The turntable is convenient for the position adjustment of the nut sleeve, and the operation is more convenient.

Preferably, a handle is arranged on the turntable. Convenient for holding and exerting force.

Preferably, an arc-shaped groove is arranged on the clamping block. The arc-shaped groove is matched with the radian of the connecting shaft, so that the positioning of the connecting shaft can be matched conveniently.

Preferably, anti-skid patterns are arranged in the arc-shaped grooves. The connecting shaft is prevented from being deviated due to uneven stress.

The beneficial effects of the utility model are as follows:

the utility model has simple structure, convenient operation, convenient force application, and can adjust the distance between the two connecting shafts to a set position, thereby facilitating the replacement of the connecting plates or the shaft rings, improving the construction efficiency and shortening the construction time.
