Description

Technical Field

[0001] The present application relates to the field of mechanical technology, and in particular to a tapping wrench for fixing bolts of a crank of an oil pump. Background Art

[0002] In the petroleum industry, the special wrench for striking the crank fixing bolts attached to the pumping unit is in a suspended state when removing or tightening the fixing bolts, especially when removing or tightening the spare caps of the fixing bolts. When the employee uses a sledgehammer to strike and hit the special wrench, the special wrench is easily knocked away or falls onto the bolts below, which increases the difficulty of the striking operation and easily causes personal injury accidents. Therefore, we propose a wrench for striking the crank fixing bolts of the pumping unit. Summary of the invention

[0003] The present application provides a striking wrench for the crank fixing bolt of an oil pump to solve the problem in the prior art that when removing or tightening the fixing bolts, especially when removing or tightening the spare caps of the fixing bolts, the special striking wrench is in a suspended state and personnel need to assist in holding the special striking wrench. When employees use a sledgehammer to strike and swing the special wrench, the special wrench is easily knocked away or dropped onto the bolt below, which increases the difficulty of the striking operation and is also prone to cause personal injury accidents.

[0004] In order to solve the above technical problems or at least partially solve the above technical problems, the present application provides a pumping unit crank fixing bolt tapping wrench, comprising:

[0005] The wrench head has a support mechanism fixedly welded to the outside of the end surface of the wrench head at the plum blossom hole position, and the support mechanism can support and clamp the upper part of the pumping unit crank mounting bolt position.

[0006] Optionally, the thickness of the supporting mechanism is the same as the thickness of the fixing bolts of the pumping unit crank.

[0007] Optionally, the support mechanism has a shape that half surrounds the plum blossom hole.

[0008] Optionally, a plum blossom hole is penetrated through the middle of the wrench head.

[0009] Optionally, a wrench handle is fixedly welded to the outer side of the wrench head.

[0010] Optionally, the wrench handle is rectangular in shape.

[0011] Optionally, the upper end surface of the supporting mechanism is horizontal.

[0012] The above technical solution provided by the embodiment of the present application has the following advantages compared with the prior art:

[0013] The device provided in the embodiment of the present application is based on the original percussion wrench. On one side of the plum blossom hole of the special wrench, a half-length supporting mechanism equal to the height and diameter of the fixing bolt is welded, which is used to support the percussion wrench. When the percussion wrench is struck or swung by a sledgehammer, it will not fall off or be easily knocked away. Due to the supporting effect of the supporting mechanism, when removing or tightening the spare cap of the fixing bolt, there is no need for personnel to hold it, which increases the safety of operation, reduces the labor intensity of employees, and improves work efficiency due to its ease of operation.

[0022] like Figure 1-2 As shown, the embodiment of the present application provides a tapping wrench for fixing bolts of a crank of an oil pumping unit, comprising:

[0023] The wrench head 1 has a supporting mechanism 3 fixedly welded to the outside of the end surface of the wrench head 1 at the position of the plum blossom hole 2, and the supporting mechanism 3 can support and clamp the upper part of the pumping unit crank mounting bolt position.

[0024] Specifically, the function of the supporting mechanism 3 is to provide support for the striking wrench when removing or tightening the fixing bolt cap, so that the striking wrench does not need to be operated by hand, thereby increasing the safety of equipment operation.

[0025] like Figure 1 and Figure 2 As shown: the thickness of the supporting mechanism 3 is the same as the thickness of the fixing bolts of the pumping unit crank.

[0026] like Figure 1 As shown: the shape of the supporting mechanism 3 is a shape that half surrounds the plum blossom hole 2.

[0027] Specifically, the supporting mechanism 3 can be in an arc shape or a polygonal shape.

[0028] like Figure 1 As shown: a plum blossom hole 2 is formed through the middle of the wrench head 1 .

[0029] Specifically, the plum blossom hole 2 is for sleeve connection on the fixing bolt nut of the crank of the oil pumping unit.

[0030] like Figure 1 and Figure 2 As shown: a wrench handle 4 is fixedly welded to the outer side of the wrench head 1.

[0031] Specifically, the wrench handle 4 can be struck by an external device to apply force to the wrench head 1 .

[0032] like Figure 1 and Figure 2 As shown: the shape of the wrench handle 4 is rectangular.

[0033] Specifically, the rectangular wrench handle 4 can be easily struck by external equipment.

[0034] like Figure 1 As shown: the upper end surface of the supporting mechanism 3 is horizontal.

[0035] Specifically, the upper end surface of the supporting mechanism 3 is the supporting contact surface.

[0036] When the device is in use, the plum blossom hole 2 of the wrench head 1 is sleeved on the nut of the pumping unit crank mounting bolt, and the supporting mechanism 3 is clamped on the upper part of the pumping unit crank mounting bolt, so that the overall structure composed of the wrench head 1 and the wrench handle 4 is movably clamped on the upper part of the mounting bolt. At this time, the wrench handle 4 is directly hit by an external tool to rotate the overall structure composed of the wrench head 1 and the wrench handle 4, so that the pumping unit crank mounting bolt is removed.

[0037] The above is only a specific implementation of the present application, so that those skilled in the art can understand or implement the present application. It will be apparent to those skilled in the art that various modifications to these embodiments are possible, and the general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features applied for by the present application.
