A sealing ring removal device

Abstract

The invention discloses a device for dismantling a seal ring. The device comprises a push rod, a disc cover and clamping jaws, wherein a push disc is arranged at one end of the push rod perpendicularly; the push rod is sleeved with the disc cover, and three or more radial sliding rails are arranged on the disc cover; each clamping jaw is arranged inside the corresponding radial sliding rail and is capable of moving along the corresponding radial sliding rail, one radial sliding rail corresponds to one clamping jaw, the end, extending out of the corresponding radial sliding rail, of each clamping jaw is used for being fixed to an installing hole, the side, far away from the push disc, of the disc cover is provided with a clamping device connected with the clamping jaws, and the clamping device controls the clamping jaws to move in the radial sliding rails correspondingly. Each clamping jaw of the device is clamped in the corresponding installing hole provided with the seal ring, the seal ring is pushed out of the installing hole by pushing the push rod, and therefore the dismantling operation of the seal ring is achieved. The device is simple in structure and convenient to operate, the manpower can be saved, the personal injuries can be prevented, in addition, the contour structure of the seal ring is protected, the service life of the seal ring is prolonged, and the device is suitable for being used for the installation and maintenance of underground coal mine equipment.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a sealing ring removal device. Background technique [0002] In the underground operation of modern coal mines, the cable lead-in device of explosion-proof electrical equipment is often used. The device is usually equipped with a housing, a connecting joint, a pressure plate, and a sealing ring to seal the device. [0003] During the cable lead-in operation, the sealing ring needs to be removed from the connecting joint, but due to the long-term extrusion in the device, the sealing ring and the housing have formed a tight connection, and the removal process is very difficult. [0004] In the prior art, operators usually use tools such as screwdrivers or iron rods to remove the sealing ring. During the process, it is easy to cause scratches and bruises to the personnel, and it is also easy to cause damage to the sealing ring, resulting in a decrease in the sealing pe...

Problems solved by technology

[0003] When carrying out the cable lead-in operation, the sealing ring needs to be removed from the connection joint, but due to the long-term extrusion in the device, the sealing ring has formed a tight connection with the housing, etc., and the removal process is very difficult

[0004] In the prior art, operators usually use tools such as screwdrivers or iron rods to remove the sealing ring. During the process, it is easy to cause scratches and bruises to the personnel, and it is also easy to cause damage to the sealing ring, resulting in a decrease in the sealing performance of the sealing ring. , so that the seal cannot be used again
