Description

Crane traveling coupling bolt dismounting tool

Technical Field

The utility model belongs to crane overhauls the apparatus field, especially relates to a crane walks capable shaft coupling bolt extracting tool.

Background

The bridge crane is an essential production device for steel plants. Wherein, the traveling coupling bolts of the bridge crane all adopt connecting pieces with high strength and close fit. In daily maintenance, when the coupler is opened for checking and oiling or the bolt is replaced, the bolt needs to be beaten by a big hammer. Because the motor, the brake wheel, the speed reducer and other equipment are arranged on two sides of the coupler, the device can not be swung by using a sledge hammer, and if gas welding cutting is adopted, a plurality of adverse factors exist, such as material annealing, easy occurrence of fire disasters and the like; if the selected bolt is not tightly matched, the bolt hole is deformed, and the coupler is scrapped.

Disclosure of Invention

The utility model discloses a purpose aims at solving the problem that the walking shaft coupling bolt of bridge crane dismantles the difficulty, provides one kind and can shorten maintenance activity duration, improves the walking shaft coupling bolt extracting tool of crane of labor efficiency.

Therefore, the utility model discloses the technical solution who takes does:

a tool for disassembling a crane walking coupler bolt comprises a handle, a clamp handle, a screwing ring and a clamp support; the flat straight section of the L-shaped forceps handle is a jaw, the vertical section is a forceps arm, external threads are arranged on the forceps arm, a U-shaped forceps holder is integrally connected with the front end of the straight rod-shaped handle, a U-shaped opening of the forceps holder is movably clamped on the forceps arm, an anti-falling rod is arranged on the U-shaped opening of the forceps holder, and a circular tightening ring is connected on the forceps arm on the non-working side of the forceps holder through threads.

The utility model has the advantages that:

the utility model discloses light in weight, it is small, easy operation, it is safe laborsaving, dismouting shaft coupling bolt need not the hammering, need not the gas welding cooperation operation, can alleviate intensity of labour, saves maintenance activity time 1.5 ~ 2. hour to avoid the damage of shaft coupling.

Drawings

FIG. 1 is a schematic view of a crane travel coupling bolt removal tool.

In the figure: the forceps comprise a jaw 1, an anti-drop rod 2, a forceps arm 3, a screwing ring 4, a forceps holder 5 and a handle 6.

Detailed Description

As shown in figure 1, the utility model discloses crane walking shaft coupling bolt extracting tool comprises anticreep pole 2, the ring of screwing 4, pincers support 5, handle 6 and pincers handle. The forceps handle is L-shaped and consists of a jaw 1 and a forceps arm 3, wherein the flat section of the forceps handle is the jaw 1, the vertical section of the forceps handle is the forceps arm 3, and the forceps arm 3 is provided with external threads. The handle 6 is a straight rod, the front end of the handle 6 is integrally connected with a U-shaped forceps holder 5, a U-shaped opening of the forceps holder 5 is movably clamped on the forceps arm 3, and an anti-falling rod 2 is arranged on the U-shaped opening of the forceps holder 5. A circular ring-shaped screwing ring 4 is connected to the clamp arm 3 on the non-working side of the clamp support 5 through threads, and the clamp support 5 can be pushed to approach the jaw 1 through screwing of the screwing ring 4, so that a coupler bolt is clamped.

The utility model relates to a set of reinforcement mechanism similar to locking pliers structure, it is ejecting or the pressure bolt of advancing through pincers handle pressure. Through the rotating of the screwing ring 4, the adjusting pliers support 5 moves towards the direction of the jaw 1 until the side face of the pliers support 5 contacts with one side end face of the coupler, meanwhile, the inner plane of the jaw 1 contacts with the end face of a bolt cap to be pressed in, the handle 6 is pulled, the jaw 1 generates horizontal thrust, the bolt pre-assembled into the coupler is pressed into a bolt hole of the coupler under the action of the thrust, otherwise, when the connecting bolt in the coupler needs to be disassembled, the tool can be installed reversely, and the horizontal thrust of the jaw 1 enables the pre-disassembled bolt to be pressed out of the bolt hole.

Claims

1. A crane walking shaft coupling bolt disassembling tool is characterized by comprising a handle, a clamp handle, a screwing ring and a clamp support; the flat straight section of the L-shaped forceps handle is a jaw, the vertical section is a forceps arm, external threads are arranged on the forceps arm, a U-shaped forceps holder is integrally connected with the front end of the straight rod-shaped handle, a U-shaped opening of the forceps holder is movably clamped on the forceps arm, an anti-falling rod is arranged on the U-shaped opening of the forceps holder, and a circular tightening ring is connected on the forceps arm on the non-working side of the forceps holder through threads.
