Description

Technical Field

[0001] This utility model relates to a rapid automatic explosion-proof sealing ring removal device, belonging to the technical field of mining equipment. Background Technology

[0002] With the long-term development of mines, underground safety in coal mines is of paramount importance. Gas and coal dust explosions constantly threaten mine safety. The main cause of most gas and coal dust explosions is sparks generated when electrical equipment fails to explode. The quality of the sealing rings in explosion-proof equipment directly affects the explosion-proof performance of the electrical equipment. In underground use, the small gap between the explosion-proof sealing rings and the casing makes it difficult to remove them during wiring, easily causing damage and affecting work efficiency. Damaged sealing rings can lead to a failure to explode in electrical equipment, directly endangering safe production in the mine. Utility Model Content

[0003] The purpose of this invention is to provide a fast and automatic explosion-proof sealing ring removal device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rapid automatic explosion-proof sealing ring removal device, comprising a fixed plate, a sliding eye, a positioning bolt, an explosion-proof sealing ring, a fixed plate, a bolt rod, a spring auxiliary support frame, and a stable grip frame. The sliding eye machined on both sides of the fixed plate positions and installs the positioning bolt. The bolt rod is fitted with a spring auxiliary support frame, which passes through a threaded hole at the center of the fixed plate and is sequentially positioned and connected to the explosion-proof sealing ring and the fixed plate.

[0005] Preferably, the spring auxiliary support frame consists of a positioning mounting ring, a support spring, a limiting nut, and a rubber washer. A support spring is positioned between the two positioning mounting rings, a rubber washer is installed on the rear positioning mounting ring, and a limiting nut is installed on the front positioning mounting ring.

[0006] Preferably, the stable grip frame consists of a bracket, a handle, a limit stop bar, and a side buffer spring assembly. The handle and the limit stop bar of the bracket crossbar are horizontally positioned and welded together, and the side buffer spring assembly is fixedly installed on both sides of the handle with nuts.

[0007] Preferably, the bolt rod has a reverse thread design.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] The spring-assisted support frame consists of a positioning mounting ring, a support spring, a limit nut, and a rubber washer. The reverse-threaded bolt rod passes through the explosion-proof sealing ring and is installed by connecting with the threaded hole of the plug plate. The support spring is squeezed by the limit nut and works with the positioning mounting ring and the rubber washer to always maintain a stable and elastic support for the center position of the fixed plate, preventing the fixed plate from shifting and causing eccentricity during the removal process. Operate the equipment to turn the bolt rod clockwise to remove the explosion-proof sealing ring intact.

[0010] The stable grip frame consists of a bracket, a handle, a limit stop bar, and a side buffer spring assembly. The handle of the stable grip frame, together with the limit stop bar and the side buffer spring assembly, enables a stable grip on the fixed plate. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] like Figures 1-4 As shown, a rapid automatic explosion-proof sealing ring removal device includes a fixed plate 1, a sliding eye 2, a positioning bolt 3, an explosion-proof sealing ring 4, a blocking plate 5, a bolt rod 6, a spring auxiliary support frame 7, and a stable gripping frame 8. The sliding eye 2 machined on both sides of the fixed plate 1 positions and installs the positioning bolt 3. The bolt rod 6 is fitted with the spring auxiliary support frame 7, which passes through the threaded hole at the center of the fixed plate 1 and is sequentially positioned and connected to the explosion-proof sealing ring 4 and the blocking plate 5.

[0018] The spring-assisted support frame 7 consists of a positioning mounting ring 9, a support spring 10, a limiting nut 11, and a rubber washer 12. The support spring 10 is positioned between the two positioning mounting rings 9, the rubber washer 12 is installed on the rear positioning mounting ring 9, and the limiting nut 11 is installed in front of the front positioning mounting ring 9. The support spring 10 is compressed and cooperates with the positioning mounting ring 9 and the rubber washer 12 to always stably and elastically support the center position of the fixing plate 1, so as to avoid the fixing plate 1 from shifting and causing eccentricity during the removal process.

[0019] The stable grip frame 8 consists of a bracket 13, a grip 14, a limiting stop bar 15, and a side buffer spring assembly 16. The grip 14 and the limiting stop bar 15 of the bracket 13 crossbar are horizontally positioned and welded together. The side buffer spring assembly 16 is fixedly installed on both sides of the grip 14 with nuts. The limiting stop bar 15 limits the position of the grip 14, and the buffer spring of the side buffer spring assembly 16 provides structural buffering for the grip 14, thereby improving the stability of the grip on the fixed plate 1.

[0020] The bolt rod 6 is designed with reverse threads. Various tools such as electric wrenches, adjustable wrenches, and open-end wrenches can be used to rotate the bolt rod clockwise to remove the explosion-proof sealing ring 6 intact, which improves work efficiency and prevents the occurrence of equipment explosion failure.

[0021] Specific usage: A rapid automatic explosion-proof sealing ring removal device. A plug plate is fixed inside the explosion-proof sealing ring. The positioning bolt with the sliding eye is installed by docking with the equipment. The diameter of the sliding eye is 12mm and the distance between the eyes is 82mm-170mm, which can meet the needs of various types of equipment. The reverse threaded bolt rod passes through the explosion-proof sealing ring and is installed by docking with the threaded hole of the plug plate. The support spring is squeezed by the limiting nut, and the positioning installation ring and rubber gasket keep the center position of the fixed plate stable and elastic, so as to avoid the fixed plate shifting and causing eccentricity during the removal process. The operator turns the bolt rod clockwise to remove the explosion-proof sealing ring intact. The handle of the stable grip frame, together with the limiting stop and the side buffer spring group, realizes the stable grip of the fixed plate.

[0022] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
