Abstract
The utility model relates to a motor shifting device of an oil pumping machine, which consists of a jackscrew and a jackscrew seat, wherein the head part of the jackscrew is provided with a cylindrical thrust assembly consisting of a press cap, a jacking plate, a bearing, a bolt and a jacking cap, wherein the center of the jackscrew head is provided with a female thread which is matched with the bolt to press the jacking plate on the jackscrew head, the bearing is embedded inside the jacking cap, the jacking cap is covered on the jacking plate, a bearing ball is pressed on the jacking plate, the press cap is connected with an opening end part of the jacking cap in a threading way and is in a sliding fit with the jackscrew head, the bolt and the jacking plate rotate together with the jackscrew, and the jacking cap and the bearing body are free from rotating. The contact area for jacking the motor seat is increased, the jacking point is stable and firm, and the rotation motion of the jackscrew is changed to the straight-line motion through the thrusting force. When adjusting the position of the motor, the time and the labor can be saved, so the time and the labor can be saved when adjusting the looseness of a triangular belt or replacing the triangular belt of the oil pump machine.
Description
One, technical field
The utility model relates to a kind of by mobile pumping-unit motor position, regulates V belt degree of tightness mechanism, specifically a kind of pumping-unit motor shift unit.
Two, background technology
Oil pumper is a run-on facility in the open air, V belt is the key link of transmission of power, oil pumper running a period of time, V belt will tired loose skidding or disconnected taking off, will reduce the reciprocating jig frequency of oil pumper as untimely adjustment, influence crude output, and also can burn out V belt, adjusting V belt or changing V belt mainly is to adjust the front and back position of the motor end of on jackscrew, used jackscrew is by the threaded engagement between jackscrew bar and the jackscrew seat, rotates, and makes jackscrew head on motor cabinet, motion before and after on the motor cabinet slide rail, the jackscrew head is very thin in addition because jackscrew rotates, the slippage always of the position of top motor cabinet, and torsional forces is very big between jackscrew head and the motor cabinet, it is also hard especially to twist jackscrew, and the oil recovery workman thinks that the adjusting V belt is very difficult.
Three, summary of the invention
The purpose of this utility model provides a kind of pumping-unit motor shift unit, solves above-mentioned prior art and regulates the hard problem of V belt.
The technical solution of the utility model realizes in the following manner:
The utility model is made up of jackscrew and jackscrew seat, it is characterized in that designing the cylindrical thrust assembly that a cover is made up of pressure cap, top board, bearing, bolt and top cap on the jackscrew head, jackscrew head center is provided with box thread and cooperates with bolt top board is pressed on the jackscrew head, be inlaid with bearing in the cap of top, the top cap is buckled on the top board, and bearing bead is pressed on the top board, pressure cap is threaded with top cap open end, be slidingly matched with the jackscrew head, bolt and top board rotate with jackscrew, and top cap and bearing body do not rotate.
The utility model compared with the prior art, its remarkable advantage is that rotatablely moving of jackscrew become rectilinear motion by the thrust assembly, and increased the contact area of top motor cabinet, the summit is firm, torsional forces between jackscrew and the motor cabinet has been become linear thrust, it is time saving and energy saving to adjust the motor front and back position, and it is time saving and energy saving promptly to adjust the elasticity of V belt or change V belt.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
1-jackscrew seat 2-jackscrew 3-pressure cap 4-top board 5-bearing 6-bolt 7-top cap among the figure
Five, the specific embodiment
For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:
The utility model is made up of jackscrew 2 and jackscrew seat 1, it is characterized in that on the jackscrew head of jackscrew 2, designing the cylindrical thrust assembly that a cover is made up of pressure cap 3, top board 4, bearing 5, bolt 6 and top cap 7, jackscrew head center is provided with box thread and cooperates with bolt 6 top board 4 is pressed on the jackscrew head, be inlaid with bearing 5 in the top cap 7, top cap 7 is buckled on the top board 4, bearing bead is pressed on the top board 4, pressure cap 3 is threaded with top cap 7 open ends, be slidingly matched with the jackscrew head, bolt and top board rotate with jackscrew, and top cap and bearing body do not rotate.
When using the utility model, jackscrew seat 1 is stuck in the motor sliding-rail groove, cylindrical thrust assembly is aimed at motor cabinet, twist the jackscrew rotation with the lever that is inserted in the jackscrew head end circular hole, the jackscrew rotation is advanced, bolt and top board rotate with jackscrew, top cap and bearing body do not rotate, rotatablely moving of jackscrew become the rectilinear motion of top cap, and having increased the contact area of top motor cabinet, firmly not slippage of summit has become linear thrust to the torsional forces between jackscrew and the motor cabinet, it is time saving and energy saving to regulate the motor front and back position, and it is time saving and energy saving promptly to adjust the elasticity of V belt or change V belt.
