Description
Technical Field
The utility model belongs to the technical field of large-scale chemical industry special compressor equipment, and particularly relates to a detachable slipper column pin crosshead for a compressor.
Background
The slide shoe of the crosshead part of the large reciprocating piston type compressor is usually integrated with the crosshead, a Babbitt alloy layer is poured, and after the crosshead and a slideway are worn, the gap between the crosshead and the slideway is too large, so that the crosshead cannot be continuously used and needs to be replaced, and great waste exists; the cross head pin adopts the cylindric lock, and the cylindric lock is rotatable in the cross head, and consequently the cylindric lock has the copper alloy bush with cross head contact segment, and the easy wearing and tearing of copper alloy bush in operation process are lost efficacy, if change into the taper pin, in operation process, because the cross head conical surface receives the yawing force, when the cross head body is not good with the cross head pin joint research, the cross head pin often takes place the accident of flying out.
Disclosure of Invention
The utility model aims at the problems and provides the detachable slipper pintle crosshead which is safe, reliable, saves equipment cost and is easy to maintain.
In order to achieve the above object, the present invention adopts the following technical solutions, and the present invention includes a crosshead body and a crosshead pin, and is characterized in that: the two sides of the crosshead body are provided with detachable sliding shoes through screws, and gaskets are arranged between the sliding shoes and the crosshead body.
In a preferred embodiment of the present invention, the cross pin is a cylindrical pin, and two ends of the cross pin extend from two ends of a pin hole of the cross head body and are fixed by a retaining ring at an opening of the pin hole.
As another preferable scheme of the present invention, the surface of the shoe is provided with an installation groove, and the screw is arranged in the installation groove.
As a third preferred scheme of the utility model, a cylindrical pin hole is arranged on the surface of the crosshead, and angle limiting holes corresponding to the cylindrical pin hole are arranged on the sliding shoe and the gasket; angle limiting pins are arranged in the angle limiting holes and the cylindrical pin holes; the crosshead body surface is also provided with an axial displacement limiting block, and the slipper and the gasket are provided with axial limiting grooves matched with the axial displacement limiting block.
As a fourth preferred aspect of the present invention, a central oil hole is formed in the center of the crosshead pin, end oil outlet holes are formed at both ends of the central oil hole, a middle oil outlet hole connected to the central oil hole is formed in the middle of the crosshead pin, and the number of the middle oil outlet holes is 3 at intervals of 120 °.
In a fifth preferred embodiment of the present invention, a connection key is provided between one end of the crosshead pin and the crosshead body.
The utility model has the beneficial effects that: 1. the slipper is of a detachable structure, and the clearance between the slipper and the slideway is adjusted through the gasket, so that if the crosshead slipper is worn, the adjustment can be carried out through the gasket, the slipper can be independently replaced, and the crosshead does not need to be replaced.
2. The crosshead pin of the utility model adopts the cylindrical pin instead of the taper pin, thereby solving the accident problems of large lateral force and flying-out of the crosshead pin.
3. The crosshead pin and the crosshead body are connected by adopting key connection, so that the crosshead pin is prevented from rotating, the original copper sleeve structure of the crosshead cylindrical pin is cancelled, and the problem of wear failure of the copper sleeve is avoided.
4. The cross oil supply structure in the middle of the crosshead pin is changed into a 120-degree uniform 3-oil supply structure, so that the strength in the middle of the crosshead pin is increased, and the problem of fracture of the crosshead pin from the middle is solved.
5. The two ends of the crosshead pin are limited by the check ring structures instead, the fastening and positioning structures of the cover plate bolts on the two sides of the existing structure are eliminated, and the falling accident that the cover plate bolts are loosened in the running process of the crosshead pin is avoided.
