Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic devices, in particular to a hydraulic device which is convenient to maintain. Background Art

It is driven by an engine or an electric motor, sucking oil from the hydraulic oil tank, forming a pressure oil discharge, and sending it to the actuator. Hydraulic pumps are divided into gear pumps, plunger pumps, vane pumps and screw pumps according to their structure.

[0003] At present, when the hydraulic pump is used and maintained, since the hydraulic pump is usually composed of an integral body, when the hydraulic oil of the hydraulic pump needs to be replaced, the residue inside the hydraulic pump needs to be discharged first, and when discharging, the staff needs to use tools to clean it, which is not only inefficient but also increases the workload of the staff. For this reason, we propose a hydraulic device that is easy to maintain. Utility Model Content

The bottom of the spring four is fixedly connected with a resistance rod two, and the cleaning plate is penetrated by the resistance rod three and is slidably connected with the resistance rod three. When the moving block resists downward to the bottom of the hydraulic pump, the resistance rod three pushes the resistance rod two. When the resistance rod two just breaks away from the cleaning plate, the spring one pushes the telescopic rod to make the cleaning plate move outward, thereby achieving the purpose of cleaning the bottom of the sealing disk. When the staff adds hydraulic oil to the hydraulic pump, the hydraulic oil pushes the sealing disk to move upward. When the moving block moves to the top of the hydraulic pump, the resistance rod one at the top of the hydraulic pump causes the resistance rod one to drive the rotating rod to rotate downward, and then the pull rope fixed on the rotating rod is driven. The pull rope causes the telescopic rod to be retracted, which drives the cleaning plate to be retracted, and the spring four pushes the resistance rod two to re-clamp the cleaning plate, thereby completing the limiting of the cleaning plate.

[0007] Preferably, the top of the connecting column is rotatably connected to a threaded rod, and the top of the threaded rod is fixedly connected to a knob. The threaded rod passes through the connecting piece and is threadedly connected to the connecting piece. When the knob is rotated, the knob drives the threaded rod to rotate, thereby applying pressure to the connecting column.

[0008] Preferably, a disc is fixedly connected to the bottom of the connecting column, one end of spring 2 is fixedly connected to the bottom of the disc, the other end of spring 2 is fixedly connected to the inner side of the hydraulic pump, the bottom of the disc is fixedly connected to a pillar, the bottom of the pillar is fixedly connected to a valve, the connecting column presses the disc downward, the disc applies pressure to the pillar, and the pillar applies pressure to the valve, thereby opening the valve to allow the hydraulic oil to flow out.

[0009] Preferably, the support penetrates the hydraulic pump and is slidably connected to the hydraulic pump, so that the support can drive the valve to move.

[0010] Preferably, the connecting column passes through the hydraulic pump.

[0011] Preferably, a fixing hole is provided on the surface of the clamping member, and the fixing hole can be used to fix an object when in use.

[0012] Compared with the prior art, the utility model provides a hydraulic device that is easy to maintain and has the following beneficial effects:

[0013] 1. When the hydraulic device is easy to maintain, when the staff replaces the hydraulic oil and the hydraulic oil is released from the hydraulic pump, the negative pressure drives the sealing disk and the moving block to move in the hydraulic pump, thereby cleaning the hydraulic oil remaining on the inner wall of the cleaning pump, so that the hydraulic oil is cleaned more cleanly without the need for the staff to manually use tools to clean it, thereby improving the work efficiency.

[0014] 2. When the hydraulic device is easy to maintain, when the staff replaces the hydraulic oil, they only need to rotate the knob to open the valve through the threaded rod to allow the hydraulic oil to flow out of the hydraulic pump. BRIEF DESCRIPTION OF THE DRAWINGS

When the staff adds the hydraulic oil of the line to the hydraulic pump 2, the hydraulic oil pushes the sealing plate 5011 to move upward. When the moving block 502 moves to the top of the hydraulic pump 2, the top of the hydraulic pump 2 resists the rod 1 508 so that the resisting rod 1 508 drives the rotating rod 507 downward to rotate, and the rotating rod 507 fixed to the rotating rod 507 drives the pull rope 506, and the pull rope 506 retracts the telescopic rod 504, thereby driving the cleaning plate 503 to retract, and the spring 4 5014 pushes the resisting rod 2 5015 to re-clamp the cleaning plate 503, thereby completing the position limiting of the cleaning plate 503.
