Abstract
The key puller is applied to the construction of mechanical equipment maintenance. The pull rod is a cylindrical rod, a round handle is arranged at the upper end of the pull rod, and a ring body is arranged at the lower part of the handle; the outer wall of the pull rod is sleeved with an impact sliding hammer, the impact sliding hammer is cylindrical and is provided with a central hole, and the lower end of the pull rod is fixed on the connector body through threads; the joint body is cylindrical and is provided with a central hole, the upper end of the central hole of the joint body is provided with internal threads, and the internal threads are connected with the lower end of the pull rod; a transverse circular through hole is formed in the joint body, and the diameter of the circular through hole is 8-20 mm; screws M8 to M20 are inserted into the circular through holes. The effect is as follows: the working method that the conventional chest expander utilizes spiral or hydraulic tension to pull out the shaft key is changed, the shaft key is disassembled by utilizing the sliding impact force of the heavy hammer, and the problem that the shaft key of the mine field maintenance equipment is difficult to disassemble is well solved.
Description
Technical field
The utility model relates to the oil field or other industrial and mining enterprises are engaged in the construction of machinery maintenance, and the specific purpose tool of particularly a kind of oil pumper and the dismounting of other main equipment reduction box axle key is a kind of key puller.
Background technology
At present, the conventional type beam pumping unit is as ground installation extensive use in oilfield exploitation of mechanical oil recovery, but oil pumper is in impact for a long time, in the adverse circumstances vibrating, expose to the sun and rain, need regular maintenance; In the oil pumper maintenance, need dismantle the reduction box crank sometimes, the dismounting crank is the very work of difficulty of part; The key that is difficult on the output shaft (crank axle) is not drawn out easily, and no specific purpose tool can't put on a spurt; Often dismantle the crank needs two hours even the longer time, waste time and energy, delay the duration.
The utility model content
The purpose of the utility model is: a kind of key puller is provided, and when solving the maintenance oil pumper, the not quick detachable problem of reduction gearbox output shaft key is increased work efficiency.
The technical scheme that the utility model adopts is: key puller, and comprise pull bar, impact sliding hammer and fittings body, it is characterized in that: pull bar is the cylinder body rod, in the upper end of pull bar knop is arranged, and in the bottom of handle torus is arranged; On the outer wall of pull bar, be with one and impact sliding hammer, impacting sliding hammer has centre bore for the cylinder bodily form, impacts sliding hammer could slide and clash into pull bar on pull bar torus lower plane.Screw thread is fixed on the fittings body in the lower end of pull bar.Described fittings body has centre bore for cylinder shape, in the upper end of the centre bore of fittings body internal thread is arranged, and fittings body is through the lower end of internal thread cylinder lever connecting rod; Horizontal manhole is arranged on the fittings body, and the diameter of manhole is between 8～20mm; In manhole, can insert the screw rod of M8～M20, can connect axle key, make axle key loosening and extract through the jarring of impacting sliding hammer through screw rod.
The beneficial effect of the utility model: the utility model key puller; Changed the method for work that pulling force that conventional chest expander utilizes spiral or hydraulic pressure is extracted axle key; The impulsive force dismounting axle key that utilizes weight to slide preferably resolves the difficult problem of mining site maintenance of equipment axle key dismounting.It is little to have volume, easy to carry, simple to operate, flexibly and fast.
Description of drawings
Fig. 1 is the utility model key puller structural profile sketch map.
Among the figure, the 1-pull bar, 2-impacts sliding hammer, 3-fittings body.
The specific embodiment
Embodiment 1: with a key puller is example, and the utility model is done further explain.
Consult Fig. 1.The utility model key puller comprises pull bar 1, impacts sliding hammer 2 and fittings body 3.Pull bar 1 is the cylinder body rod of diameter 12mm, and length is 400mm.There is knop upper end at pull bar 1, and it is the torus of 35mm that diameter is arranged in the bottom of handle.On the outer wall of pull bar 1, be with one and impact sliding hammer 2, impacting sliding hammer 2 has centre bore for the cylinder bodily form, and the quality of impacting sliding hammer 2 is 0.8Kg.Screw thread is fixed on the upper surface of fittings body 3 in the lower end of pull bar 1.Described fittings body 3 is for the cylinder bodily form of diameter 36mm has centre bore, in the upper end of the centre bore of fittings body 3 internal thread arranged, and fittings body 3 is through the lower end of internal thread cylinder lever connecting rod 1.Horizontal manhole is arranged, the diameter 16mm of manhole on the fittings body 3; In manhole, insert the screw rod of M16.
