Technical Field
[0001] The utility model relates to the field of industrial equipment, in particular to an electric torque hydraulic wrench pump. Background Art
[0002] With the development of industry, it is very important to connect two parts in the manufacturing process. The existing conventional connection methods include threaded nuts, flanges, etc. When connecting, the two parts are connected by turning the screws with the threads. However, when connecting some large parts, in order to ensure the stability of the connection, the screws are turned very tightly. When removing them, it is time-consuming and laborious by manual labor. Many manufacturers will use electric torque hydraulic wrench pumps to remove the screws.
[0003] Electric torque hydraulic wrench pumps provide a convenient and efficient way to apply torque, suitable for work such as tightening bolts or nuts. This type of equipment usually consists of the following parts: an electric drive device, a hydraulic pump unit and a control system. The working principle of this equipment is that the hydraulic pump unit generates high-pressure liquid through the electric motor to pass it to the torque wrench through the connecting parts to apply the required torque. The pressure generated by the hydraulic pump can be adjusted by the control system to achieve precise control of the applied torque; electric torque hydraulic wrench pumps are usually used in occasions where large torque needs to be applied, such as the installation and maintenance of large mechanical equipment, shipbuilding and other fields. Its advantages include accurate torque application, high work efficiency, and applicability to large bolts.
[0004] However, when the existing electric torque hydraulic wrench pump connects the pump and the wrench through a connecting pipe, high-pressure liquid is used to provide thrust to achieve the rotation of the screw. After use, there will be residual liquid in the connection, which will accumulate and merge with dirt over a long period of time, causing the electric torque hydraulic wrench pump to leak during operation, resulting in the wrench not working or rotating. Utility Model Content

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0032] The following describes an embodiment of the utility model based on its overall structure.
[0033] An electric torque hydraulic wrench pump, such as Figure 1-8 As shown, an electric torque hydraulic wrench pump body 1, a pair of connecting structures 2 are symmetrically arranged on one side of the electric torque hydraulic wrench pump body 1, and a connecting hole 3 is opened on the electric torque hydraulic wrench pump body 1 to cooperate with the connecting structure 2, and the electric torque hydraulic wrench pump body 1 is connected to the connecting structure 2 through the connecting hole 3, and then a conduit is connected, and the other end of the conduit is connected to the hydraulic wrench, and the control of the hydraulic wrench can be achieved by controlling the pressure of the electric torque hydraulic wrench pump body 1;
[0034] Specifically, the connecting structure 2 includes a connecting pipe 201, and the connecting pipe 201 is arranged in cooperation with the connecting hole 3 at one end close to the electric torque hydraulic wrench pump body 1. A sealing ring 4 is arranged at the connection between the connecting structure 2 and the electric torque hydraulic wrench pump body 1. The sealing ring 4 is used to prevent leakage when the electric torque hydraulic wrench pump body 1 is working. The connecting pipe 201 is arranged in cooperation with the end away from the electric torque hydraulic wrench pump body 1 with a connecting head 202. By connecting the connecting head 202 to an external conduit and connecting the other end of the conduit to the hydraulic wrench, the control of the hydraulic wrench is achieved.
[0035] Further, a blocking cleaning structure 203 is provided in the connecting tube 201 in cooperation with the connecting head 202, and the blocking cleaning structure 203 includes a first rotating ring 2031, a scraper 9 is provided on the outer circle of the first rotating ring 2031, a second rotating ring 2032 is provided at the bottom of the first rotating ring 2031, a sliding groove 2037 is provided at the bottom of the first rotating ring 2031, and a limiting block 2033 is provided on the second rotating ring 2032 in cooperation with the sliding groove 2037, and the first rotating ring 2031 and the second rotating ring 2032 are rotatably arranged through the provided sliding groove 2037 and the limiting block 2033;
[0036] On the basis of the above structure, a stopper 2034 is provided on the first rotating ring 2031, and a limit rod 10 is provided on one end of the connector 202 close to the connecting pipe 201 in cooperation therewith. A cavity 7 is provided on the first rotating ring 2031 in cooperation with the stopper 2034, and the stopper 2034 extends to the cavity 7. A through hole is provided in the slide groove 2037 in cooperation with the cavity 7 to connect to the outside, and an air pump 8 is provided at the through hole, and the pressure in the cavity 7 is controlled by the air pump 8. In this way, the stopper 2034 is controlled to be ejected from the cavity 7. When ejected, the limit rod 10 is rotated by the connection head 202 to cooperate with the stopper 2034 to drive the first rotating ring 2031 to rotate. The inner ring of the first rotating ring 2031 is provided with a first cross bar 2035, and the inner wall of the second rotating ring 2032 is provided with a second cross bar 2038.

In this way, when the connecting head 202 is taken out, the blocking cleaning structure 203 is used to seal the inside of the connecting pipe 201. At the same time, the scraper 9 is taken out to scrape and clean the inner wall of the connecting pipe 201 to prevent liquid accumulation from causing dirt to adhere, which causes the electric torque hydraulic wrench pump body 1 to fail to work normally.
[0037] The slide groove 2037 is provided with a guide groove 6 to cooperate with the air pump 8, and the guide groove 6 gradually decreases from high to low. When in use, the limit block 2033 squeezes the air pump 8 to move it, so that the air pump 8 moves to the lower part of the slide groove 2037, so that it will not be triggered again, and the air pump 8 loses control over the cavity 7, so that the first rotating ring 2031 rotates only one circle and then stops rotating, and the flexible baffle 5 can be fully unfolded.
