Abstract
The utility model relates to a special tool for a large-belt wheel jigger of an oil extractor, which consists of a stress rod and two clamping blocks, wherein the two clamping blocks are respectively installed on the stress rod in parallel through a pin roll. The special tool is convenient, labor is saved, the large-belt wheel jigger of the oil extractor can be safely and reliably operated, and the sliding phenomenon can be effectively overcome, so the potential safety hazards are eliminated.
Description
Technical field
The utility model belongs to pumping unit appurtenance technical field, is a kind of oil pumper big belt pulley jiggering specific purpose tool.
Background technology
In the management process of extraction oil well, often need carry out oil pumper maintenance, carry polished rod annotate vapour, liquidate apart from, bump regular job such as pump, must be referred to as jiggering usually earlier by the big belt pulley of artificial rotation oil pumper during unloading.The mode that present jiggering is taked is: be stuck in pipe wrench on the wheel rim of big belt pulley, in the big belt pulley cylindrical tangential direction application of force big belt pulley rotated then, and take off belt in rotation process.But because the pipe wrench design is to be used for slewing circle cylindricality workpiece, its thread form outline line is parallel with face of cylinder axis, and its thread form outline line is consistent with oil pumper big belt pulley rotation direction when being used to pull big belt pulley, therefore occurs skidding easily.Simultaneously, be subjected to force direction and design to be subjected to force direction to be 90 ° of angles because clamp handle in addition, the big belt pulley load torque is big in addition, so not only labour intensity is big during jiggering, and usually causes the fracture of pincers handle because of overexerting, and has serious potential safety hazard.
The utility model content
The purpose of this utility model provides a kind ofly the time can effectively be avoided skidding pulling the belt of oil pumping machine opinion, and can guarantee safety, and easy to use, labour-saving oil pumper big belt pulley jiggering specific purpose tool.
Realize that the technical scheme that the purpose of this utility model is taked is: this instrument is made up of boosting-rod and two clamps, and two clamps are installed in parallel on the boosting-rod by bearing pin respectively.
Described two clamps can freely rotate around bearing pin.
The involutory surface of described two clamps is the plane, is laid with the anti-skidding teeth of the bar shaped vertical with boosting-rod on this involutory surface.
The oil pumper big belt pulley jiggering specific purpose tool of making according to such scheme, it is stuck in when pulling on the big belt pulley, can carry out the jiggering operation of oil pumper big belt pulley convenient and strength-saving, safely and reliably, and can overcome skidding effectively, eliminate safe hidden trouble.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Structural representation when Fig. 2 is the utility model user mode.
The specific embodiment
Referring to Fig. 1, Fig. 2, oil pumper big belt pulley jiggering specific purpose tool of the present utility model has a boosting-rod 1, is fixed with two bearing pin 2a, 2b on this boosting-rod 1, and bearing pin 2a, 2b are coated with clamp 3 respectively, constitutes F shape structure.Two clamps 3 can freely rotate around bearing pin, so that better with the wheel rim of oil pumper big belt pulley 5 chucking.The involutory surface of two clamps 3 is the plane, is laid with to be used for the anti-skidding teeth 4 of bar shaped of interlock oil pumper big belt pulley on involutory surface, and the direction and the boosting-rod of the anti-skidding teeth 4 of bar shaped are perpendicular.During use two clamps 3 are stuck on the wheel rim of big belt pulley 5 relatively,, therefore can pull big belt pulley 5 like a cork, carry out the jiggering operation of oil pumper big belt pulley 5 because the length of boosting-rod 1 is longer, both convenient and strength-saving, safe and reliable again.
