Description

Technical Field

[0001] This utility model relates to the field of auxiliary safety equipment technology, and in particular to an anti-slip locking device for the safety rope of a ladder used for maintenance of an accident door slot in a power generation tunnel. Background Technology

[0002] Within the scope of water conservancy and hydropower projects, power generation tunnels serve as crucial water conveyance and power generation channels, making routine maintenance and repair indispensable. Emergency gate slots, as key structures ensuring the safe operation of power generation tunnels, require regular inspection to ensure normal functioning in emergencies. During maintenance, workers must use ladders to move up and down, but the environment around these ladders is complex and poses certain safety risks.

[0003] The current locking device requires manual release when moving. Upon release, the internal locking structure completely fails, leaving the device fully unlocked and losing all restraint on the safety rope. This means that if maintenance personnel slip or fall while moving on the ladder leading to the emergency access gate in the power generation tunnel, the safety rope cannot be locked in time, leaving them in a freefall state. This significantly compromises their safety and the smooth progress of maintenance work. Utility Model Content

[0004] The present invention aims to provide a safety rope anti-slip locking device for the ladder used in the maintenance of emergency access gates in power generation tunnels, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A safety rope anti-slip locking device for a ladder used in the maintenance of an accident access gate in a power generation tunnel includes a fixed plate. The fixed plate is connected to a first limiting plate, a second limiting plate, a first guide plate, and a second guide plate. The fixed plate is rotatably connected to a first pressure block and a second pressure block, which respectively cooperate with the first and second guide plates. The first and second pressure blocks are respectively connected to a first connecting member and a second connecting member. The first and second connecting members are rotatably connected to a first connecting rod and a second connecting rod. The fixed plate is rotatably connected to a first support rod and a second support rod, which are rotatably connected to the first and second connecting rods. The first and second support rods are respectively connected to a first pull ring and a second pull ring, both of which are connected to a connecting rope. Both sets of connecting ropes are connected to a safety rope, which is connected to a hook.

[0007] Preferably, the first pressing block and the second pressing block are respectively connected with saw teeth one and saw teeth two.

[0008] Preferably, rubber strips are connected to the end faces of the first limiting plate, the second limiting plate, the first guide plate, and the second guide plate.

[0009] Preferably, the corners of the first limiting plate, the second limiting plate, the first guide plate, and the second guide plate are arranged in an arc shape.

[0010] Preferably, the fixing plate is connected to two sets of mounting plates, each set of mounting plates is connected to a leaf spring, and the two sets of leaf springs are respectively connected to pressure block one and pressure block two.

[0011] Preferably, the first limiting plate, the second limiting plate, the first guide plate, and the second guide plate are all connected to rollers.

[0012] Preferably, the hook is equipped with a safety device to prevent accidental opening at the locking point.

[0013] Preferably, the fixing plate, limiting plate one, limiting plate two, guide plate one, and guide plate two are all made of high-strength alloy material.

[0014] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0015] (1) This technical solution sets up structures such as pull ring one, pull ring two, support rod one, support rod two, connecting rod one, connecting rod two, connector one, connector two, pressure block one and pressure block two. When maintenance personnel pull pull ring one and pull ring two respectively, the locking state of the device can be gradually released, avoiding the high risk brought about by the complete release of the locking state of the traditional locking device. If an accident occurs during the movement of maintenance personnel, the part of the structure that is not completely released can still respond in time and quickly lock the safety rope to reduce the risk of falling. While ensuring smooth movement, it maximizes the safety of operation and provides reliable safety protection for the maintenance work of the power generation tunnel accident gate slot.

[0016] (2) By setting saw teeth one and saw teeth two, a deep engagement can be formed with the surface of the safety rope. By increasing the friction and mechanical clamping effect at the contact point, the safety rope is prevented from slipping when under force, forming a more reliable mechanical lock and improving the locking device's gripping ability and anti-slip effect on the safety rope.

[0017] (3) By setting rubber strips, a flexible buffer can be formed when the device comes into contact with the safety rope, avoiding direct friction between metal parts and the safety rope, thus extending the service life of the safety rope and improving the overall durability of the device.

[0018] (4) By setting arc-shaped limiting plates one, two, one guide plate, and two guide plates at the bends, the risk of wear and tear on the safety rope during its movement within the device can be reduced, allowing for a smooth transition, dispersing stress, reducing friction and compression with the plate, and preventing sharp edges from scratching and damaging the protective layer on the safety rope surface, thus ensuring the structural integrity of the safety rope. This enhances the safety and reliability of the entire anti-slip locking device, providing a more solid guarantee for the life safety of maintenance personnel at the power generation tunnel accident access gate.

[0019] (5) By setting up mounting plates and leaf springs, a reliable automatic reset and constant force compression mechanism is provided for pressure blocks one and two. The elastic potential energy of the leaf springs pushes pressure blocks one and two, keeping them in a stable compression of the safety rope and forming a pre-tensioned state. Once the maintenance personnel fall, the safety rope is subjected to force, and pressure blocks one and two, which are in a pre-tensioned state, do not need to wait for additional power transmission or structural triggering. They immediately lock through the tight engagement of the saw teeth with the safety rope, greatly shortening the locking reaction time. This avoids the delay caused by the need to overcome mechanical gaps and start transmission components in traditional locking devices, and can fix personnel at the first moment of a fall, minimizing the risk of fall injury and providing reliable safety protection for maintenance personnel.

[0020] (6) By setting rollers, rolling friction can replace the traditional sliding friction between the plate and the safety rope, reducing the resistance when the safety rope moves, so that maintenance personnel can drive the safety rope to slide more smoothly during climbing or moving, reducing operational fatigue.

[0021] (7) By setting up a safety device to prevent accidental opening, the accidental fall caused by hook loosening is eliminated, providing a reliable guarantee for the life safety of maintenance personnel.

[0022] (8) By setting up a fixed plate, a limiting plate one, a limiting plate two, a guide plate one and a guide plate two made of high-strength alloy materials, it has excellent tensile and compressive strength, can withstand large external impacts, and enhances the reliability of the device.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0028] like Figure 1-3The device shown is an anti-slip locking device for safety ropes on a ladder used for maintenance of an emergency access door in a power generation tunnel. It includes two sets of fixing plates 1, which are connected to a first limiting plate 17, a second limiting plate 20, a first guide plate 3, and a second guide plate 23. All three plates are made of high-strength alloy material. The first limiting plate 17 and the first guide plate 3 together form the entry channel for the safety rope, while the second limiting plate 20 and the second guide plate 23 together form the exit channel. Rubber strips 13 are attached to the end faces of each of the limiting plates 17, 20, 3, and 23. The corners of the limiting plates 17, 20, 3, and 23 are arc-shaped. Rollers 18 are connected to the inner side of the side wall of the fixed plate 1 near the first limit plate 1, the second limit plate 20, the first guide plate 3, and the second guide plate 23.

[0029] like Figure 1-3 As shown, the fixed plate 1 is rotatably connected to pressure block 6 and pressure block 21, which are located below guide plate 3 and above guide plate 23, respectively. The portions of pressure block 6 and pressure block 21 that contact the safety rope are respectively connected to sawtooth 15 and sawtooth 24. The fixed plate 1 is connected to two sets of mounting plates 9, each set of mounting plates 9 being connected to leaf springs 8, which are respectively connected to pressure block 6 and pressure block 21. When the leaf springs 8 are in a balanced state, both pressure block 6 and pressure block 21 are in a state of compressing the safety rope. Pressure block 6 and pressure block 21 are respectively connected to connector 7 and connector 22, which are rotatably connected to connecting rod 5 and connecting rod 19. The two sets of fixed plates 1 are rotatably connected to support rod 2 and support rod 16, which are rotatably connected to connecting rod 5 and connecting rod 19, respectively. Support rod 12 and support rod 26 are respectively connected to pull ring 14 and pull ring 24, and both pull ring 14 and pull ring 24 are connected to connecting ropes 12. The ends of the two sets of connecting ropes 12 are connected to a safety rope 11, and the end of the safety rope 11 is connected to a hook 10. The lock of the hook 10 is equipped with a safety device to prevent accidental opening.

[0030] In the initial state of the device, the leaf spring 8 is in equilibrium, continuously pushing the pressure block 6 and pressure block 21 to compress the safety rope. At this time, the saw teeth 15 and 24 are tightly engaged with the safety rope, forming a stable pre-tension state to ensure that maintenance personnel will not slip due to accidents when stationary. When maintenance personnel need to move, they pull the pull ring 4 or pull ring 24 upwards, causing the support rod 2 / support rod 16 to rotate. Through the connecting rod 5 / connecting rod 29 and the connecting piece 7 / connecting piece 22, the pressure block 6 / pressure block 21 rotates along the guide plate 3 / guide plate 23 respectively, releasing part of the compression on the safety rope. The required length of safety rope can then be manually pulled out from the sides of the two sets of fixed plates 1, allowing the safety rope to move smoothly with the assistance of the roller 18. After releasing the pull ring 4 / pull ring 24, pull the pull ring 24 / pull ring 4, and pull the safety rope out from the top or bottom of the two sets of fixed plates 1. If an accidental fall occurs during the movement, the downward force of the maintenance personnel will instantly cause the pull ring to be pulled downward. At this time, the pressure block 6 and pressure block 21, which are not completely released from locking, will quickly re-squeeze the safety rope under the combined action of the elastic restoring force of the leaf spring 8 and the downward pulling force. The saw teeth 15 and saw teeth 24 will once again penetrate into the surface of the safety rope to achieve rapid locking.

[0031] The specific implementation process is as follows:

[0032] In use, pull upwards on ring 14 and ring 2, and pass the safety rope sequentially through the entry channel formed by limiting plate 17 and guide plate 3, and the exit channel formed by limiting plate 20 and guide plate 23. Securely connect the hook 10 on the safety rope 11 to the safety belt buckle of the maintenance personnel using the anti-accidental release safety device. When the maintenance personnel climb the ladder, keep the device hanging naturally; the safety rope is compressed and fixed in the initial locked state. When upward movement is required, first pull upwards on ring 214 to pull the upper safety rope out from the side of the fixed plate 1. After releasing ring 214, pull upwards on ring 4 to pull the safety rope piled up on the side of the fixed plate 1 out from the bottom of the fixed plate 1. When downward movement is required, simply reverse the operation.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
