Description
Technical field
The utility model is related to mule head pin field of fixation devices, and specifically a kind of new pumping unit mule head pin is fixed anti-safely
Protection unit.
Background technology
Horse head pin of pumping unit is the important device for connecting and fixing horse head and walking beam, and its manufacture craft is simple, it is desirable to but
Must be fine, i.e., coordinate with horse head, walking beam jack must tightly, otherwise oil pumper in operation process, run to when horse head,
Just occur at bottom dead centre caused because gap is excessive horse head repeatedly vibration and make too much noise, just occur when serious and tear
The phenomenon of horse head junction is split, is such as found not in time, there is also makes horse head drop and be damaged and pumping unit and smash well
The serious accident of mouth device.Cushioning wedge in gap, above walking beam jackscrew be installed, a plurality of jackscrew be even installed, in certain journey
Some problems are solved on degree.But this problem is not solved fundamentally, so that causing horse head to snap.Prior art
In occur in that a kind of safe fixed-guard of mule head pin, but have the following disadvantages：
1st, the safe fixed-guard of mule head pin of the prior art for horse head and walking beam both sides only with 1 bolt
Fastener is fixed, and due to the flip-flop movement of horse head and walking beam always repeatedly, bolt clamp device can be caused to loosen, if
After this bolt clamp device loosens, bolt clamp device will be ineffective, and horse head and walking beam will loosen, and cause horse head
Pin loosens.
2nd, the safe fixed-guard of mule head pin of the prior art only by bolt clamp device in horse head and walking beam
The clamping plate bottom of junction is fixed, and is not fixed at the top of the clamping plate of horse head and walking beam junction, by tightening spiral shell
After bolt fastener fastens clamping plate, using clamping plate and horse head, walking beam junction as fulcrum, at the top of clamping plate can by
Outer moment of flexure, easily makes clamping plate flexural deformation, causes clamping plate to lose the clamping action to horse head, walking beam.
3rd, the safe fixed-guard of mule head pin of the prior art lacks spacing to the progress of at the top of horse head pin and top
Fixed device, makes mule head pin fixation security performance not high, mule head pin only by the method for be fixedly clamped horse head and walking beam
Son also has the possibility skidded off from top.
