Abstract
The utility model provides a lower abutting device for a horsehead of a beam-pumping unit and aims at overcoming the shortcomings of the existing horsehead-detachable beam-pumping unit, such as unstable abutting of the horsehead with the front end face of the walking beam, easy production of abnormal sound, and non-steady operation of the pumping unit. The lower abutting device for the horsehead of the beam-pumping unit comprises a walking beam and a horsehead; a baffle plate is fixedly mounted on the upper end of the front end face of the walking beam, the horsehead is suspended on the baffle plate of the walking beam by use of a suspension shaft, a supporting plate is fixedly mounted under the suspension shaft of the horsehead, the supporting plate is parallel to the suspension shaft, and a base plate is fixedly mounted on the front end face of the walking beam in a position corresponding to the supporting plate of the horsehead. The lower abutting device has the beneficial effects the contact stress of the horsehead and the walking beam is more reasonable due to reasonable structure, abnormal sound is eliminated, and stable operation of the pumping unit can be guaranteed.
Description
Technical field
The utility model relates to a kind of beam pumping unit, especially relates to abutment means under a kind of mule head of beam pumping unit.
Background technology
Beam pumping unit adopts detachable horse head to be the mule head of beam pumping unit structure of in recent years releasing, simple with its manufacturing process, and workover treatment conveniently obtains more and more many application.
At present, the detachable horse head of beam pumping unit is that the cylindrical shaft (hitching axis) by being welded on horse head is affiliated on the baffle plate of walking beam front top, the middle part of horse head be installed with gripper shoe parallel with hitching axis, gripper shoe should abut against on the whole width in lower end of walking beam front end-plate in theory.Because horse head and walking beam are all weldments, be subject to the impact of welding deformation, the cylindrical shaft of horse head upper end and gripper shoe are difficult to guarantee parallel accuracy in axial length direction, make the contact surface lower end of gripper shoe and walking beam front end face be abutted against position and are difficult to guarantee that the length direction at axle fits completely; Under the impact of horse head fluctuating load, horse head can produce distortion, causes occurring abnormal sound of movement simultaneously, and oil pumper operation is steady not.
Utility model content
In order to overcome horse head that the beam pumping unit of existing detachable horse head exists and walking beam front end face, be abutted against unstablely, easily send abnormal noise, the deficiency that oil pumper can not even running, the utility model provides abutment means under a kind of mule head of beam pumping unit.
The utility model solves the technical scheme that its technical problem adopts: under mule head of beam pumping unit, abutment means comprises walking beam, horse head, the upper end of walking beam front end face is installed with baffle plate, horse head hangs on the baffle plate of walking beam by hitching axis, below the hitching axis of horse head, be installed with gripper shoe, gripper shoe is parallel with hitching axis, at the walking beam front end face of the gripper shoe correspondence position of horse head, is installed with backing plate.
The beneficial effects of the utility model are, rational in infrastructure, make the contact of horse head and walking beam more reasonable, eliminate abnormal voice, guarantee that oil pumper can operate steadily.
Accompanying drawing explanation
Fig. 1 is the structural representation of abutment means under the utility model mule head of beam pumping unit.
In figure: 1. walking beam, 2. baffle plate, 3. horse head, 4. hitching axis, 5. gripper shoe, 6. backing plate.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.But those skilled in the art should know, the invention is not restricted to the listed specific embodiment, as long as spirit according to the invention all should be included in protection scope of the present invention.
Referring to accompanying drawing 1.Under the utility model mule head of beam pumping unit, abutment means comprises walking beam 1, horse head 3, the upper end of walking beam 1 front end face is installed with baffle plate 2, horse head 3 hangs on the baffle plate 2 of walking beam 1 by hitching axis 4, below the hitching axis 4 of horse head 3, be installed with gripper shoe 5, gripper shoe 5 is parallel with hitching axis 4, at walking beam 1 front end face of gripper shoe 5 correspondence positions of horse head 3, is installed with backing plate 6.Conventionally backing plate 6 is weldingly fixed on walking beam 1 front end-plate bottom, backing plate 6 contacts with the gripper shoe 5 that horse head is abutted against use for 3 times, can guarantee the contact area of backing plate 6 and gripper shoe 5, eliminating horse head 3 is abutted against with 1 time abutment surfaces one side part of walking beam, avoid horse head 3 being subject to causing horse head 3 stress deformations in the poor larger situation of polished rod load, produce abnormal sound problem.It is rational in infrastructure, has guaranteed to be abutted against under horse head the middle part that contact site concentrates on the length direction horse head gripper shoe of hitching axis, and the force part of walking beam also occurs in the middle simultaneously, and make the contact of horse head and walking beam more reasonable, oil pumper can even running.
It should be noted that above-described embodiment is example and unrestricted the present invention, those skilled in the art can design a lot of alternate embodiments and not depart from the claim scope of this patent.
Claims (1)
1. abutment means under a mule head of beam pumping unit, comprise walking beam, horse head, the upper end of walking beam front end face is installed with baffle plate, horse head hangs on the baffle plate of walking beam by hitching axis, below the hitching axis of horse head, be installed with gripper shoe, gripper shoe is parallel with hitching axis, it is characterized in that: walking beam (1) front end face at gripper shoe (5) correspondence position of described horse head (3) is installed with backing plate (6).
