Description

Technical Field

[0001] The utility model relates to the technical field of gas construction tools, in particular to a safety rope fixing device for hole opening operations. Background Art

[0002] In the past, during gas construction, when working at the external riser opening (working at height), a safety rope would be fixed to a steel pipe about 2.5 meters long. However, the steel pipe lacked effective fixation and did not meet the requirements of high hanging and low use. In addition, the steel pipe was heavy and inconvenient to carry.

[0003] The existing technology, CN2018206698044, is a retractable template support rod structure, which uses a screw rod to achieve retraction. It takes a long time to adjust and needs to be rotated. At the same time, the two ends support the hole opening, which has poor strength. If the hole surface roughness is low, the force is small and the safety in the studio is low.

[0004] Therefore, it is necessary to design a safety rope fixing device for hole operation to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a safety rope fixing device for cave opening operations to overcome the above-mentioned deficiencies in the current prior art.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A safety rope fixing device for cave opening operations comprises an outer tube and an inner tube which is partially embedded in the outer tube and can be telescopically movable, and is characterized in that a first L-shaped supporting block is provided at the end of the inner tube which leaks out of the outer tube; a second L-shaped supporting block is provided at the end of the outer tube where the inner tube is not provided, a sleeve is provided at the other end away from the second L-shaped supporting block, a quick clamp chuck is provided on the sleeve, a through groove is provided on the sleeve, a limiting guide rail is installed on the inner tube, the limiting guide rail is provided through the inner tube, and an inclined rack is provided on the limiting guide rail.

[0008] Preferably, the fixed end of the quick clamp chuck is connected to the through slot.

[0009] Preferably, cushion blocks are provided on both the first L-shaped supporting block and the second L-shaped supporting block.

[0010] Preferably, a safety rope fixing ring is provided on the outside of the outer tube.

[0011] The beneficial effects of the present invention are as follows: the present technical solution uses mutually nested pipes, and simultaneously provides limiting guide rails and quick clamp chucks for mutual locking on the two groups of pipes, thereby quickly performing telescopic locking. In order to improve the strength, a rack is provided on the limiting guide rail to prevent loosening and slipping. At the same time, L-shaped supporting blocks are provided at both ends, one side of which supports the top surface and the other side supports the side surface, thereby increasing the bearing capacity. The overall structure is simple, easy to carry, and the device cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Reference Figure 1 A safety rope fixing device for cave operations, comprising an outer tube 1 and an inner tube 2 partially embedded in the outer tube and capable of telescopic movement;

[0018] A first L-shaped support block 21 is provided at the end of the inner tube 2 that leaks out of the outer tube 1; the first L-shaped support block 21 is threadedly connected to the inner tube 2, and the height of the first L-shaped support block 21 is adjusted by rotating it, thereby performing short-distance adjustment;

[0019] A second L-shaped supporting block 11 is provided at the end of the outer tube 1 where the inner tube 2 is not provided. To improve strength, the sides of the first L-shaped supporting block 21 and the second L-shaped supporting block 11 are in contact with the sides of the hole to support the sides and further improve strength.

[0020] A sleeve 3 is provided at the other end away from the second L-shaped holding block 11, a quick clamp chuck 31 is provided on the sleeve, a through slot is provided on the sleeve 3, and a fixed end of the quick clamp chuck 31 is connected to the through slot;

[0021] A limiting guide rail 22 is installed on the inner tube 2. The limiting guide rail 22 is arranged to penetrate the inner tube 2 and is fixed by bolts. In order to improve the strength, the limiting guide rail 22 can also be welded to the inner tube 2. The limiting guide rail 22 is partially placed in the through groove and can move along the through groove. In order to prevent the quick clamp chuck 31 from sliding after being fixed and affecting the strength, an inclined rack 4 is provided on the limiting guide rail 22. The clamping end of the quick clamp is engaged with the rack 4 to fix it.

[0022] To prevent excessive squeezing force on the upper and lower sides of the hole when holding and fixing, a pad 12 is provided on each of the first L-shaped holding block 21 and the second L-shaped holding block 11 to protect the upper and lower cooling surfaces of the hole. The pad 12 is made of rubber material to play a protective role.

[0023] In order to facilitate manual taking, a safety rope fixing ring 5 is provided on the outside of the outer tube 1;

[0024] This implementation case, reference Figure 2 , manually hold the safety rope fixing ring 5 to move the entire device to the hole, and set the safety rope loop on the outer tube 1 and lock it, set the second L-shaped holding block 11 to hold the lower end of the hole, and at the same time set the side plate against the side of the bottom hole, manually loosen the quick clamp chuck 31, extend the inner tube 2 upward, and the outer tube 1 does not move. Since the limiting guide rail 22 is placed in the through groove of the sleeve 3, the synchronous limiting guide rail 22 moves synchronously until the first L-shaped holding block holds the top of the hole, and the side is attached to the side of the hole, and then the quick clamp chuck 31 is locked to the limiting guide rail 22 to complete the fixation.

[0025] The benefits of the present invention are that the present invention has the following technical solutions: through mutually nested pipes, limiting guide rails and quick clamp chucks for locking each other are respectively provided on the two groups of pipes, thereby quickly performing telescopic locking; in order to improve the strength, a rack is provided on the limiting guide rail to prevent loosening and slipping; at the same time, L-shaped supporting blocks are provided at both ends, one side of which supports the top surface and the other side supports the side surface, thereby increasing the bearing capacity; the overall structure is simple, easy to carry, and the device cost is low.

[0026] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
