Abstract
The utility model discloses a kind of chain Quick disassembling tool, it is characterised in that：Using scissor caliper structure, tong arm one end is jaw, clamping chain roller, tong arm other end loading screw, tong arm is exerted a force by nut, the both ends of chain is tensed, realizes the fast assembling-disassembling to chain.Chain Quick disassembling tool is made up of left clamp arm, right clamp arm, rotating shaft, screw rod, rotating nuts, the jaw in the place of screw rod and right clamp arm annular opening contacts, the place of rotating nuts and the contact of left clamp arm U-type groove and left and right pincers is designed with circular arc, adapt to different claming angles, ensure enough clamping contact areas, expand the use range of instrument.Compared with prior art, the utility model is compact-sized, easy to operate, and securely and reliably, service efficiency is high, manufacturing cost is low, solves the problems, such as that heavy-duty chain dismounting is difficult.
Description
Technical field
The invention belongs to petroleum works equipment technical field, is related to a kind of chain Quick disassembling tool.
Background technology
There are the following problems for prior art：Most of existing oil-well rig, workover rig are machine driving, winch, rotating disk with
Based on chain drive.Chain used in petroleum machinery is heavy-duty chain, there is single strand chain and multiple rows of chain, and chain pitch is big, transmits work(
Rate is big, and weight is big, and size is big, and maintenance, dismounting, installation, the replacing of chain are very frequent, without suitable extracting tool, workload
Greatly, operating difficulties, efficiency are low.
The content of the invention
To solve the defects of prior art is present, a kind of chain Quick disassembling tool has been invented, being capable of fast assembling-disassembling correspondence
The heavy-duty chain of model, improve operating efficiency.
Chain Quick disassembling tool of the present invention is made up of left clamp arm, right clamp arm, rotating shaft, screw rod, rotating nuts.
The technical solution adopted by the present invention：Using scissor caliper structure, tong arm one end is jaw, clamping chain roller,
Tong arm other end loading screw, tong arm is exerted a force by rotating nuts, the both ends of chain is tensed, realizes the fast assembling-disassembling to chain.
Described left clamp arm one end is jaw, and the other end is U-type groove, and right clamp arm one end is jaw, and the other end is circular hole.
The jaw of the left and right tong arm is provided with circular arc, and chain roller coincide, and adapts to different claming angles, ensures enough
Clamping contact area, expand the use range of instrument.
Described screw rod one end is T-shaped button, and the other end is polished rod, and polished rod end is outer six side, and screw rod and right clamp arm circular hole connect
Tactile place is provided with sphere, ensures there is enough contact area and stress intensity when jaw folding is of different sizes.
The rotating nuts carry rotary handle, can Quick fastening and release, rotating nuts and left clamp arm U-type groove contact
Place be provided with sphere, ensure there is enough contact area and stress intensity when jaw folding is of different sizes.
Compared with prior art, the present invention is compact-sized, easy to operate, and securely and reliably, service efficiency is high, manufacturing cost
It is low, solve the problems, such as that heavy-duty chain dismounting is difficult.

Embodiment
The present invention is described further below in conjunction with Figure of description and specific preferred embodiment, but therefore not limited
Protection scope of the present invention processed.
As shown in figure 3, the chain Quick disassembling tool of the present embodiment is by left clamp arm 4, right clamp arm 5, rotating shaft 3, screw rod 2, rotation
Turn nut 1 forms.
The technical scheme that the present embodiment uses：Using scissor caliper structure, tong arm one end is jaw, and clamping chain rolls
Son, tong arm other end loading screw, tong arm is exerted a force by rotating nuts, tenses the both ends of chain, realizes and the quick of chain is torn open
Dress.
In the present embodiment, left clamp arm one end is jaw, and the other end is U-type groove, and right clamp arm one end is jaw, and the other end is circle
Hole.
In the present embodiment, the jaw of left and right tong arm is provided with circular arc, and chain roller coincide, and adapts to different claming angles,
Ensure enough clamping contact areas, expand the use range of instrument.
In the present embodiment, screw rod one end is T-shaped button, and the other end is polished rod, and polished rod end is outer six side, screw rod and right clamp arm
The place of annular opening contacts is provided with sphere, ensures there is enough contact area and stress intensity when jaw folding is of different sizes.
In the present embodiment, rotating nuts carry rotary handle, can Quick fastening and release, rotating nuts and left clamp arm U
The place of type groove contact is provided with sphere, ensures there is enough contact area and stress intensity when jaw folding is of different sizes.
Described above is only presently preferred embodiments of the present invention, and above-mentioned specific embodiment is not limitation of the present invention,
Retouching, modification or the equivalent substitution that all those skilled in the art are made as described above, belong to the protection model of the present invention
Enclose.
