Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic power equipment, in particular to a hydraulic power element with an oil leakage protection function. Background Art

[0002] Hydraulic power elements are key components in hydraulic systems. Their primary function is to convert the mechanical energy of the prime mover into the pressure energy of the oil, providing power for the entire hydraulic system. Hydraulic power elements typically refer to hydraulic pumps, which provide a flow rate at a certain pressure to the hydraulic system.

[0003] A plunger pump is a hydraulic pump that uses the reciprocating motion of a plunger within a cylinder to create a change in the sealed volume, achieving oil suction and discharge. Based on the arrangement of the plungers and the direction of their movement, plunger pumps can be divided into two categories: radial and axial. The operating principle of a plunger pump is to use the reciprocating motion of the plunger to change the sealed volume, thereby achieving oil suction and discharge.

[0004] When a plunger pump is in use, the top of the pump body expands and contracts to provide power. This expansion port is prone to leakage, which can cause power loss in the pump body. Therefore, the plunger pump can be protected by adding an oil leakage protection device. However, the oil leakage protection device used in traditional plunger pumps is usually an integrated design wrapped around the outside of the plunger pump, making it difficult to replace damaged parts. Therefore, a hydraulic power element with oil leakage protection function is proposed. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a hydraulic power element with oil leakage protection function, which has the advantages of good stability and easy maintenance. It solves the problems that traditional hydraulic power elements are prone to oil leakage, resulting in insufficient power and inconvenient maintenance of protection devices.

[0006] In order to achieve the above-mentioned purpose of good stability and easy maintenance, the utility model provides the following technical solution: a hydraulic power element with oil leakage protection function, comprising a base, a power body plugged and fixed on the top of the base, and a protection component provided on the top of the base;

[0007] The protection component includes a connecting tube rotatably connected to the outside of the base, a sealing gasket slidably connected to the inner wall of the base, a fixing tube threadedly connected to the inner wall of the connecting tube, several positioning plates threadedly connected to the top of the fixing tube, several annular sleeves arranged on the inner wall of the positioning plate, a fixing seat arranged on the side of the annular sleeve, and a sealing rubber ring arranged on the inner wall of the fixing seat.

[0008] Furthermore, the power body includes a fixed rod and a movable rod, a sealing cover is fixedly installed on the top of the fixed rod, and the sides of the sealing cover and the fixed rod are provided with limiting slots used in conjunction with the fixing seat.

[0009] Furthermore, a plurality of limit blocks are fixedly installed on the inner bottom wall of the base, the top of the limit block is inserted into the bottom of the power body, the sealing gasket is an annular structure wrapped around the outside of the power body and the inner wall and the outer wall of the power body are slidably connected.

[0010] Furthermore, the positioning plate is a semicircular arc structure, the inner side wall of the positioning plate is provided with a plurality of positioning slots, the outer side wall of the positioning plate is provided with thread patterns, and the top of the positioning plate is provided with a plurality of positioning blocks.

[0011] Furthermore, a plurality of plug-in rods are provided at the bottom of the fixing seat, and a plurality of locking arc grooves for use with the annular sleeve rods are provided on the outer sides of the sealing cover, the fixing rods and the plug-in rods.

[0012] Furthermore, the bottom side of the fixing seat is provided with a plurality of limit slots used in conjunction with the positioning block, the inner side wall of the fixing seat is provided with an annular groove, the sealing rubber ring is embedded in the annular groove and is slidably connected to the fixing seat.

[0013] Furthermore, the inner side wall of the sealing rubber ring is slidably connected to the side surface of the movable rod, and a sealing rubber pad is provided at the bottom of the fixing seat.

[0014] Compared with the prior art, the present invention provides a hydraulic power element with oil leakage protection function, which has the following beneficial effects:

[0015] 1. The hydraulic power element with oil leakage protection function is constructed by inserting the power body into the interior of the base, so that the limit block fixes the bottom of the power body, and then the fixing seat wrapped with an annular sleeve rod on the outside is passed through the top of the movable rod and nested in the top of the sealing cover, and then the outer side of the fixing seat is covered with a clamping plate. After locking the base, the fixing cylinder is rotated. Since the clamping plate is limited and cannot rotate in the fixing seat, the rotation of the fixing cylinder pulls the clamping plate and the fixing seat to move downward to a certain extent. After the clamping plate is locked at the top of the fixing cylinder, the initial fixation of the device is completed.

[0016] 2. The hydraulic power element with oil leakage protection function rotates the connecting cylinder. Since the power body and the base are fixedly limited by the limit block, and the positioning plate and the fixed cylinder are locked, the rotation of the connecting cylinder will drive the fixed cylinder to move downward. The downward movement of the fixed cylinder squeezes the internal sealing gasket to cause a slight bending deformation. The deformed sealing gasket fills the gaps between the power body, the base, the connecting cylinder and the fixed cylinder, and cooperates with the sealing rubber ring to seal the power body as a whole, thereby avoiding oil leakage accidents, thereby solving the problems of traditional hydraulic power elements prone to oil leakage, resulting in insufficient power, and inconvenient maintenance of protective devices.

[0026] In this embodiment, the power body 2 includes a fixed rod 21 and a movable rod 22. A sealing cover 23 is fixedly installed on the top of the fixed rod 21. The sealing cover 23 and the side of the fixed rod 21 are provided with limiting slots 24 used to cooperate with the fixing seat 36.

[0027] The fixing seat 36 is limited by providing a limiting notch 24 on the outer side of the power body 2 to prevent the fixing seat 36 from rotating.

[0028] In this embodiment, a plurality of limit blocks 38 are fixedly installed on the inner bottom wall of the base 1, the top of the limit block 38 is inserted into the bottom of the power body 2, and the sealing gasket 32 ​​is an annular structure wrapped around the outside of the power body 2 and the inner wall and the outer wall of the power body 2 are slidingly connected.

[0029] In this embodiment, the locking plate 34 is a semicircular arc structure, the inner wall of the locking plate 34 is provided with a plurality of locking slots 341, the outer wall of the locking plate 34 is provided with a thread pattern 342, and the top of the locking plate 34 is provided with a plurality of positioning blocks 343.

[0030] A semicircular locking plate 34 is provided on the outside of the fixing seat 36 to cooperate with the annular sleeve rod 35 to limit the fixing seat 36, so that the fixing cylinder 33 can move downward under the drive of the connecting cylinder 31, thereby locking the fixing seat 36 on the top outside of the power body 2.

[0031] In this embodiment, a plurality of plug rods 361 are provided at the bottom of the fixing seat 36 , and a plurality of locking arc grooves 39 for use with the annular sleeve rod 35 are provided on the outer sides of the sealing cover 23 , the fixing rod 21 and the plug rod 361 .

[0032] A plug-in rod 361 is provided on the outer side of the fixing seat 36 so that the fixing seat 36 and the power body 2 can maintain a relatively stable state.

[0033] In this embodiment, the bottom side of the fixing seat 36 is provided with several limit slots 362 used to cooperate with the positioning block 343, and the inner wall of the fixing seat 36 is provided with an annular groove 363. The sealing rubber ring 37 is embedded in the inside of the annular groove 363 and is slidably connected to the fixing seat 36.

[0034] A limiting latch 362 is provided on the outer side of the fixing seat 36 to nest the positioning block 343 on the top of the locking plate 34 , thereby firmly locking the fixing seat 36 on the top of the locking plate 34 , so that the locking plate 34 will not rotate relative to the power body 2 .

[0035] In this embodiment, the inner side wall of the sealing rubber ring 37 is slidably connected to the side surface of the movable rod 22 , and a sealing rubber pad is provided at the bottom of the fixing seat 36 .

[0036] A sealing rubber ring 37 is provided to wrap the movable rod 22 and cover the outer side of the movable rod 22 to prevent oil leakage.

[0037] The working principle of the above embodiment is:

[0038] By inserting the power body 2 into the interior of the base 1, the limit block 38 fixes the bottom of the power body 2, and then the fixing seat 36 wrapped with the annular sleeve 35 on the outside is passed through the top of the movable rod 22 and nested in the top of the sealing cover 23, and then the outer side of the fixing seat 36 is covered with the locking plate 34. After locking the base 1, the fixing cylinder 33 is rotated. Since the locking plate 34 is limited and cannot rotate on the fixing seat 36, the rotation of the fixing cylinder 33 pulls the locking plate 34 and the fixing seat 36 to move downward to a certain extent. After the locking plate 34 is locked at the top of the fixing cylinder 33, the initial fixation of the device is completed.

[0039] In addition, by rotating the connecting cylinder 31, since the power body 2 and the base 1 are fixedly limited by the limit block 38, and the locking plate 34 and the fixed cylinder 33 are locked, the rotation of the connecting cylinder 31 will drive the fixed cylinder 33 to move downward. The downward movement of the fixed cylinder 33 squeezes the internal sealing gasket 32 ​​to cause a slight bending deformation. The deformed sealing gasket 32 ​​fills the gap between the power body 2, the base 1, the connecting cylinder 31 and the fixed cylinder 33, and cooperates with the sealing rubber ring 37 to seal the power body 2 as a whole, thereby avoiding oil leakage accidents, thereby solving the problem that traditional hydraulic power elements are prone to oil leakage, resulting in insufficient power, and the protection device is inconvenient to maintain.
