Description

Technical Field

[0001] The utility model belongs to the technical field of hydraulic gear pumps, in particular to an anti-deviation hydraulic gear pump for mining. Background Art

[0002] A hydraulic gear pump is a rotary pump that relies on the change and movement of the working volume formed between the pump cylinder and the meshing gears to transport liquid or increase its pressure. It is mostly used in underground mining operations.

[0003] However, in the use of existing hydraulic gear pumps, the connection between the pipeline and the pump body is usually directly connected using flanges and bolts. This connection method will cause the pipeline size to change and deviate due to the effect of thermal expansion and contraction over a long period of use, affecting the flow of liquid. Therefore, there is an urgent need for a mining-use anti-deviation hydraulic gear pump to solve the above problem. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing hydraulic gear pump directly uses flanges and bolts to connect, which causes deviations between pipelines and affects the flow of liquid.

[0005] In order to achieve the above functions, the technical solution adopted by the present invention is as follows: a hydraulic gear pump with anti-drift for mining, comprising an outer shell, a motor fixedly mounted on the side wall of the outer shell, an external pipe and a liquid outlet pipe fixedly connected to the two side walls of the outer shell in a mirror-image manner, an anti-drift component is provided on one side of the external pipe, a cavity is opened inside the outer shell, the output end of the motor passes through the outer shell and extends into the cavity and is connected to a driving gear, a driven gear is meshed with the driving gear, and the driven gear is rotatably arranged on the cavity.

[0006] Furthermore, the anti-deviance component includes a corrugated tube arranged on one side of the external tube, flange components are symmetrically fixed on both side walls of the corrugated tube, and one of the flange components is fixedly connected to the external tube, a sealing ring is fixedly connected to the inner wall of the flange assembly, an inner pipe is fixedly connected to one side wall of the sealing ring, and the inner pipe is arranged inside the corrugated tube.

[0007] Furthermore, the anti-deviance component also includes a plurality of limit blocks distributed in a circular array on the outer wall of the flange component, a fixed rod is fixedly connected to one side wall of the limit block, one end of each of the two fixed rods is rotatably connected to a rotating block, a connecting rod is connected by a pin between the two rotating blocks, a spring is provided on the outer wall of the connecting rod, and both ends of the spring are fixedly connected to the two rotating blocks respectively.

[0008] Furthermore, there is a gap between the corrugated tube and the outer wall of the inner pipe.

[0009] Furthermore, the external pipe, the liquid outlet pipe and the cavity are connected to each other.

[0010] Furthermore, the flange assembly includes two flanges fixed by bolts and nuts.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows:

[0012] 1. An anti-deviation component is provided. There is a gap between the corrugated tube and the inner pipe between the two flange components in the component. The corrugated pipe is elastic and compensates for the deviation between the pipes connected at both ends, allowing the liquid to flow normally, thereby achieving the purpose of preventing deviation;

[0013] 2. A fixed rod is connected between the flange components in the anti-drift component. The fixed rod cooperates with the connecting rod connected by the rotating block and the pin and the spring to allow the corrugated tube to move horizontally to a certain extent and limit the vertical displacement.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0023] like Figure 3 and Figure 4 As shown, the anti-deviance assembly includes a corrugated tube 9 provided on one side of the external tube 3, and flange assemblies 6 are symmetrically fixed on both side walls of the corrugated tube 9. The flange assembly 6 includes two flanges fixed by bolts and nuts, and one of the flange assemblies 6 is fixedly connected to the external tube 3.
