Description

Technical Field

[0001] The utility model relates to the field of hydraulic breaker hammers, in particular to a detachable sealing sleeve of a hydraulic breaker hammer. Background Art

[0002] Hydraulic breaker can more effectively clear floating stones and soil in rock crevices when excavating the foundation of a building. Its power source is the pressure oil provided by the pump station of the excavator or loader. The principle of selecting a hydraulic breaker is to choose the most suitable hydraulic breaker according to the excavator model and the working environment.

[0003] At present, after the sealing sleeve is connected to the connection between the high-pressure oil pipe and the hydraulic breaker, the sealing sleeve may be dislocated after a long period of operation due to the vibration of the hydraulic breaker due to continuous use, which will cause hydraulic oil leakage and increase the maintenance cost. In addition, due to the leakage, the hydraulic system cannot maintain normal working pressure, the impact force and blasting effect of the hydraulic breaker may be affected, resulting in reduced work efficiency. Therefore, a detachable sealing sleeve for a hydraulic breaker is proposed to address the above problems. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art and avoid the problems of increased maintenance costs and reduced work efficiency caused by poor sealing effects, the utility model proposes a detachable sealing sleeve for a hydraulic breaker.

[0005] The technical solution adopted by the utility model to solve the technical problem is: a detachable sealing sleeve of a hydraulic breaker hammer, comprising a hydraulic breaker hammer device; a high-pressure oil pipe is inserted at the top of the hydraulic breaker hammer device, a sealing ring is sleeved on the surface of the high-pressure oil pipe, a limiting component is arranged on the surface of the high-pressure oil pipe at the top of the hydraulic breaker hammer device, and a stabilizing component is arranged on the surface of the limiting component;

[0006] The limiting assembly includes a fixed block fixedly installed on the top of the hydraulic breaker equipment, a fixed rod fixedly installed on the top of the fixed block, a sliding rod slidably connected to the surface of the fixed rod, a buffer spring fixedly installed on the end of the sliding rod close to the center of the fixed block, an arc-shaped limiting plate fixedly installed on the end of the buffer spring away from the sliding rod, a threaded rod rotatably connected to the outer wall of the fixed block, a threaded sleeve threadedly connected to the surface of the threaded rod, and a bent rod fixedly installed on the top of the surface of the threaded sleeve.

[0007] Preferably, the fixed block is in the shape of a regular hexagon, and the side of the bent rod away from the threaded sleeve is fixedly installed on the surface of the sliding rod. When the bent rod is pushed to move, it will push the sliding rod to move, and then the sliding rod will push the buffer spring and the arc limiting plate, so that the arc limiting plate abuts against the surface of the sealing ring. At this time, multiple arc limiting plates will press and stabilize the sealing ring.

[0008] Preferably, the end of the arc-shaped limiting plate away from the buffer spring is in adaptive contact with the sealing ring, the bottom end of the sealing ring is in adaptive fit with the top end of the fixed block, and the sealing ring seals the connection between the sealing ring and the fixed block through its inner wall and bottom wall.

[0009] Preferably, the stabilizing assembly comprises a hollow block fixedly mounted on the top of the fixed block, the interior of the hollow block is rotatably connected to a rotating rod, the surface of the rotating rod is provided with a bayonet, a plug rod is inserted into the top of the hollow block, a driving gear is fixedly mounted on the surface of the hollow block, a fixed sleeve is sleeved on the surface of the sealing ring, a rubber belt is arranged inside the fixed sleeve on the side close to the sealing ring, the surface of the fixed sleeve is rotatably connected to a winding rod, and the surface of the winding rod is fixedly mounted with a driven gear.

[0010] Preferably, the bayonet circle is arranged on the surface of the rotating rod, and the bottom end of the insertion rod is adapted to be engaged with the bayonet. After the rotating rod is rotated to adjust the position of the driving gear, the insertion rod can be inserted downward so that its bottom end is engaged with the inside of the bayonet, thereby limiting the position of the rotating rod.

[0011] Preferably, the driving gear and the driven gear are meshed and connected, the winding rod and the outer surface of the rubber belt are fixedly connected, the rubber belt and the sealing ring are in adaptive contact, and when the rotating rod drives the driving gear to rotate, it will drive the meshed driven gear to rotate. At this time, the driven gear will drive the winding rod to rotate, so that the winding rod drives the rubber belt to be wound and tightened on the surface of the sealing ring, thereby sealing and further limiting the surface of the sealing ring.

[0012] The utility model is beneficial in that:

[0013] The utility model sleeves the sealing ring on the connection between the high-pressure oil pipe and the hydraulic breaker equipment, and elastically limits the sealing ring through the buffer spring and the arc-shaped limiting plate, so that the sealing ring is stably limited on the surface of the high-pressure oil pipe during the operation of the hydraulic breaker equipment, and the hydraulic system is kept running at normal pressure, thereby keeping the impact force and blasting effect of the hydraulic breaker normal;

[0014] By initially limiting the sealing ring with a fixed sleeve and further limiting the sealing ring with a rubber belt, the position of the sealing ring is further kept stable, avoiding the sealing ring from shifting due to the vibration generated by the operation of the hydraulic breaker equipment, thereby allowing the hydraulic breaker equipment to maintain normal operation and avoiding the waste of hydraulic oil due to oil leakage.
