Abstract

The utility model relates to a gear disassembling tool and in particular relates to a timing gear extractor of a tractor hoist. The technical scheme adopted by the utility model is as follows: the timing gear extractor consists of a body, a screw rod and pull rods, wherein the pull rods are respectively arranged at two sides of the body, and the screw rod is arranged at the center of the body; the bottoms of the pull rods are in screwed connection with a timing gear; and the tops of the pull rods are connected with the body. The timing gear extractor has the beneficial effects of simply and rapidly solving the problem that the timing gear is difficult to take out, reducing the maintenance load, saving the maintenance cost, improving the maintenance quality and prolonging the service life of equipment.

Description

Tractor hoist timing gears extractor

Technical field

The utility model relates to a kind of gear extracting tool, particularly a kind of tractor hoist timing gears extractor.

Background technology

At present, in the maintenance process of workover rig, be mostly at home at worker-house and scene; The maintenance condition is limited, particularly in the maintenance process of the housing for timing gear in the engine heart, can not hang car body to engine; Service clearance is narrow and small during the dismounting timing gears, lacks the specific purpose tool of dismounting timing gears, dismantles timing gears sometimes and expends 4-5 hour; The jarring of the prizing of crowbar, hammer etc. is adopted in the dismounting of present domestic tractor hoist and workover rig timing gears mostly, when serious the gear spindle nose is damaged, and causes the complicated of maintenance; Both strengthen maintenance load and influenced installation quality; Shortened the service life of equipment, increased the apparatus maintenance use cost, the operation that has influenced oil-water well accounts for the well cycle.

Summary of the invention

The purpose of the utility model is exactly the above-mentioned defective that exists to prior art, and a kind of tractor hoist timing gears extractor is provided, and can solve timing gears quickly and easily and be difficult for taking out this difficult problem.

Its technical scheme is: be made up of body, leading screw, pull bar, the both sides of described body are respectively equipped with pull bar, and the center of body is provided with leading screw, and the bottom of pull bar is connected with the timing gears screw, and the top of pull bar is connected with body.

The beneficial effect of the utility model is: can solve timing gears quickly and easily and be difficult for taking out this difficult problem, reduce maintenance load, practice thrift maintenance cost, improve repair quality, prolong the service life of equipment.

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model;

Accompanying drawing 2 is vertical views of the utility model.

The specific embodiment

In conjunction with accompanying drawing 1-2, the utility model is done further to describe:

The utility model is made up of body 1, leading screw 2, pull bar 3, and the both sides of described body 1 are respectively equipped with pull bar 3, and the center of body 1 is provided with leading screw 2, and the bottom of pull bar 3 is connected with the timing gears screw, and the top of pull bar 3 is connected with body 1.

The course of work of the utility model is following: use the utility model can be when the dismounting timing gears; Earlier pull bar 3 is passed in the rectangular opening of body 1, pull bar is connected with the screw endoporus of timing gears, the centre bore of positive timing gears axle is pushed up on the knob top of leading screw; Continuous screw-in through leading screw; Timing gears are extracted, simple and practical, dependable performance.
