Description

Chain wrench with jaw

Technical Field

The utility model relates to a extracting tool especially relates to a chain spanner with claw.

Background

The chain wrench is widely applied to the disassembly and assembly processes of the rotating component, the common chain wrench is clamped on the rotating component by means of the protruding shaft of each section of the chain, and the friction force between the chain and the component is utilized to drive the component to rotate, so that the component is disassembled. However, due to the defects of the conventional chain wrench, when the rotating member is large, the chain cannot be fastened on the surface of the rotating member and is easy to slip, so that the chain cannot be disassembled by using the conventional chain wrench.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a chain spanner with jaw to the realization is to the convenient and fast's of large-scale rotating member dismouting.

The utility model discloses a realize through following technical scheme:

the utility model provides a chain spanner with claw, includes sleeve pipe, lead screw, two chains, the lead screw is arranged in the sleeve pipe hole and outside sleeve pipe threaded connection and both ends all stretched out the sleeve pipe, and the one end of two chains is fixed respectively and is equipped with the claw, and the other end of two chains links together through a can dismantle round pin hub connection, and two chains are in the position that is close to the claw respectively detachable install in the sleeve pipe both sides.

Bolts are fixed on two sides of the outer wall of the sleeve respectively, the chain is inserted into the bolts through gaps of adjacent chain links, and nuts are screwed to realize detachable connection of the chain and the sleeve.

And one end of the screw rod, which is far away from the two chains, is fixedly connected with a handle vertical to the screw rod.

Nuts are fixed at two ends of the sleeve, and the screw rod is in threaded connection with the nuts at two ends of the sleeve.

Compared with the prior art, the utility model has the following advantages:

the utility model provides a pair of chain spanner with jaw, it can dismantle two chains of connection through the sleeve pipe, and two chains can enclose into an annular structure, and the winding is at the rotating member surface that needs the dismouting to through rotatory lead screw, make the lead screw tip support tightly at the member surface, increased and rotating member between friction li, can effectively prevent to pull the in-process phenomenon of skidding of appearing, realized the dismouting convenient, quick, stable to large-scale rotating member. When one end of each of the two chain mounting claws is used as a free end, and the other end of each chain mounting claw is fixed on the sleeve, the bearing can be conveniently and quickly disassembled in a labor-saving manner, and particularly the disassembly of the bearing with smaller operable space can be completely realized by adopting the chain wrench; the function is diversified.

Drawings

Fig. 1 is a schematic view of the mounting structure for dismounting the rotating member according to the present invention.

Fig. 2 is a schematic structural diagram of the bearing dismounting device of the present invention.

Reference numbers in the figures: the novel clamp comprises a sleeve 1, a screw rod 2, a chain 3, a nut 4, a jaw 5, a detachable pin shaft 6, a bolt 7, a nut 8, a handle 9, a bearing 10 and an installation shaft 11.

Detailed Description

The embodiments of the present invention will be described in detail below, and the present embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

Referring to fig. 1 and 2, the embodiment discloses a chain wrench with jaws, which includes a sleeve 1, a screw rod 2, and two chains 3, wherein the screw rod 2 is located in an inner hole of the sleeve 1, nuts 4 are fixedly welded at two ends of the sleeve 1, and the screw rod 2 is in threaded connection with the nuts 4 at two ends of the sleeve 1. One end of each of the two chains 3 is fixedly provided with a claw 5, and the other end of each of the two chains 3 is connected together through a detachable pin shaft 6. Two chains 3 are respectively detachably arranged on two sides of the sleeve 1 at the position close to the claw 5, and the specific connection mode is as follows: bolts 7 are respectively welded and fixed on two sides of the outer wall of the sleeve 1, the chain 3 is inserted into the bolts 7 through the gaps of the adjacent chain links, and nuts 8 are screwed to detachably connect the chain 3 and the sleeve 1.

The two ends of the screw rod 2 extend out of the sleeve 1, and one end of the screw rod 2, which is far away from the two chains 3, is fixedly connected with a handle 9 perpendicular to the screw rod 2, so that the operation of an operator is facilitated.

Referring to fig. 1, when the rotating member needs to be disassembled and assembled, one ends of two chains 3, which are far away from a jaw 5, are connected by a detachable pin shaft 6 to form a whole chain 3, one end of the whole chain 3 is connected with a bolt 7 on a sleeve 1, then the whole chain 3 is wound on the outer side wall of the rotating member, and then the other end of the whole chain 3 is also connected with the bolt 7 on the other side of the sleeve 1, so that the whole chain 3 is sleeved on the outer side wall of the rotating member. Then the handle 9 is rotated so that the end of the lead screw 2 is pressed against the side wall of the rotating member, thus completing the fixed mounting between the chain wrench and the member. Then the handle 9 is pulled, and the disassembly or the assembly of the rotating component can be realized.

Referring to fig. 2, when the bearing 10 needs to be disassembled, the detachable pin 6 is pulled down, and the two chains 3 are independent. The ends of the two chains 3 remote from the jaws 5 are then mounted on the casing 1, the end with the jaws 5 being the free end. The handle 9 is positioned above, the two claws 5 are positioned below, the claws 5 on the two chains 3 are placed into two sides of the bearing 10 to be disassembled from top to bottom, the two claws 5 hook the bottoms of two sides of the bearing 10, then the handle 9 is rotated to enable the screw rod 26 to be tightly propped against the top end of the mounting shaft 11 of the bearing 10, the handle 9 is continuously rotated, and the bearing 10 can be pulled upwards to be separated from the mounting shaft 11 through the two claws 5.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
