Description

Technical Field

[0001] This utility model relates to the field of safety protection equipment for hydropower stations, and in particular to a quick-attachment device for safety ropes in hydropower stations. Background Technology

[0002] Safety protection for high-altitude operations at hydropower stations is a core aspect of ensuring the safety of maintenance personnel working at heights and near edges. Among these, the safety rope anchoring device, as a critical node in the fall protection system, directly determines the overall protective effectiveness by reliably securing the safety rope. In scenarios such as water diversion tunnel maintenance and dam gate maintenance, workers often need to use safety ropes when climbing vertically, working in mid-air, or walking near edges, and the safety rope anchorage must be higher than the work platform. However, current safety rope attachment methods have the following shortcomings: 1) When working on site, the safety rope anchor point must be several meters higher than the maintenance work surface. Before working at height, the safety rope needs to be hung on the safety anchor point. At this time, it is very risky for people to climb to the safety anchor point. A ladder must be used. This method has the characteristics that the height of the ladder cannot be adjusted and the fixation is not reliable. At the same time, it requires the assistance of many people to complete, which wastes human resources and has high safety risks.

[0003] 2) When hanging safety ropes for high-altitude operations, the traditional method of setting up maintenance platforms requires setting up platforms one by one at each anchor point, repeatedly setting up and dismantling them. At the same time, the safety risks to personnel are relatively high during the platform setting process. This method requires a long time, a lot of tools and human resources, and has the characteristics of low work efficiency, cumbersome operation and high risk. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a quick-attachment device for safety ropes in hydropower stations, which can improve the attachment efficiency and ease of operation of safety ropes.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: The safety rope quick-attachment device for hydropower stations includes a telescopic pole with a connecting plate installed at the top. The connecting plate has an insertion slot, and a lever is hinged to one side of the upper end of the insertion slot. A safety rope is installed at one end of the lever, and a locking rod is fixed to the other end of the lever. The locking rod is locked to the locking part on the other side of the insertion slot of the connecting plate.

[0006] The connecting plate is U-shaped with the upper end flaring outwards.

[0007] One end of the lever is equipped with a first hanging rod, and a hanging rope loop is placed on the first hanging rod, which is connected to a safety rope.

[0008] The hanging loop uses a ring buckle structure.

[0009] The slot is equipped with a locking mechanism that engages or disengages the locking rod.

[0010] The bottom of the mounting groove of the locking part has outwardly flared openings on the left and right sides.

[0011] The locking mechanism includes a left clamp and a right clamp, which are hinged together by a pin. A guide rod is fixed to the end of the pin. The upper ends of the two guide rods pass through the opening and extend into the control groove of the locking part. The top ends of the two guide rods are connected to a magnetic plate. The upper end of the magnetic plate is directly opposite the electromagnet on the top surface of the control groove.

[0012] Each guide rod is located in the mounting groove and is fitted with a top plate and a spring from bottom to top.

[0013] The telescopic rod and connecting plate are both made of high-strength aluminum alloy.

[0014] The telescopic pole is made of multiple sections of support rods connected by threads at both ends.

[0015] This utility model provides a quick-attachment device for safety ropes in hydropower stations, which has the following technical advantages: 1) One end of the lever of this device is hinged to the connecting plate, and the other end is locked to the locking mechanism of the locking part; and the greater the force on the safety rope, the more secure the locking state between the other end of the lever and the locking part, thus improving safety and reliability. It is particularly suitable for maintenance work in dangerous areas such as pressure steel pipes, generator floors, floodgates, busbar chambers, and corridors in hydropower stations.

[0016] 2) This device uses a telescopic rod for operation. The length of the telescopic rod can be set according to actual needs, and it can be completed without climbing a ladder, thus improving efficiency.

[0017] 3) By employing a lever, the lever can rotate to reach the locking mechanism using the force of the safety rope, or rotate away from the locking mechanism using its own gravity. The locking mechanism uses electromagnetic adsorption to open and close the left and right clamps. In this way, the lever + locking mechanism allows for quick attachment and detachment of the device from the hanging rings of the safety anchor points. It can be operated frequently without the need to build platforms for each anchor point individually. Attached Figure Description

[0027] like Figure 1-4 As shown, the hydropower station safety rope quick-attachment device includes a telescopic pole 1, which is composed of multiple sections of support rods connected end-to-end by threads. The length can be configured according to actual needs to accommodate different working heights. A connecting plate 2 is provided at the top end of the top support rod of the telescopic pole 1, and the connecting plate 2 is threaded to the top of the telescopic pole 1. The connecting plate 2 is U-shaped, with the upper end flaring outwards. A lever 3 is hinged to one end of the top of the connecting plate 2 via a pin. One end of the lever 3 has a first hanging rod 4, and a rope loop 5 is placed around the first hanging rod 4. One end of the safety rope 6 passes through the rope loop 5, and the other end of the safety rope 6 is tied to the worker. A locking rod 7 is fixed to the other end of the lever 3. A locking part 8 is provided at the other end of the corresponding top of the connecting plate 2. The locking part 8 extends laterally towards the first hanging rod 4, and a mounting groove is opened at the lower end of the locking part 8. A locking mechanism 9 is provided in the mounting groove, which clamps or releases the locking rod 7.

[0028] The locking mechanism 9 includes a left clamp 9.1 and a right clamp 9.2, which are hinged together by a pin 9.3 to form a scissor-like structure. Guide rods 9.4 are fixed to the ends of the pin 9.3 that extend beyond the left and right clamps 9.1 and 9.2, respectively. Each guide rod 9.4 is located within the mounting groove of the locking part 8, and from bottom to top, a top plate 9.5 and a spring 9.6 are sequentially fitted onto it. The upper ends of the two guide rods 9.4 pass through openings at the upper end of the mounting grooves and extend into the control groove 9.7 of the locking part 8. The top ends of the two guide rods 9.4 are connected to a magnetic plate 9.8. The upper end of the magnetic plate 9.8 is directly opposite an electromagnet 9.9 on the top surface of the control groove 9.7. The electromagnet 9.9 is energized or de-energized via a control button on the telescopic rod 1.

[0029] like Figure 5 As shown, in the unpowered state, the locking mechanism 9 moves downward under gravity, and the magnetic suction plate 9.8 is located on the lower end surface of the control groove 9.7. The lower ends of the left clamp 9.1 and the right clamp 9.2 extend out of the mounting groove of the locking part 8. Under the elastic force of the spring 9.6, the spring 9.6 pushes the top plate 9.5, and the top plate 9.5 presses the left clamp 9.1 and the right clamp 9.2, causing the left clamp 9.1 and the right clamp 9.2 to open.

[0030] like Figure 6 As shown, when energized, the magnetic plate 9.8 is attracted to the upper surface of the control slot 9.7 and fixed to the electromagnet 9.9. The lower ends of the left clamp 9.1 and right clamp 9.2 retract into the mounting slot of the locking part 8. Because the lower end of the locking part 8 has flared openings with beveled surfaces on the left and right, as the left clamp 9.1 and right clamp 9.2 retract into the mounting slot of the locking part 8, the outer ends of the left clamp 9.1 and right clamp 9.2 are restricted by the bevels and gradually move closer together, eventually clamping the locking rod 7. At the same time, the left clamp 9.1 and right clamp 9.2 push the top plate 9.5 and spring 9.6 upward, and the spring 9.6 retracts.

[0031] Preferably, the rope loop 5 adopts a ring buckle structure, model WLL0.75t (7.5kN), so that the safety rope can be put into the rope loop and locked with the buckle.

[0032] Preferably, the telescopic rod 1 and the connecting plate 2 are both made of high-strength aluminum alloy, which has excellent corrosion resistance in humid environments.

[0033] Preferably, the mounting groove of the locking part 8 faces downward and has outwardly flared openings on the left and right sides at the bottom. This facilitates the gradual closing of the left clamp 9.1 and the right clamp 9.2 during the upward movement.

[0034] Working principle and process: 1) Select multiple support rods and connect them with threaded ends to form the telescopic rod 1, so that the length of the telescopic rod 1 meets the height required for on-site use; connect the telescopic rod 1 and the connecting plate 2 with threads.

[0035] 2) Insert the hanging rope of the safety rope 6 into the hanging rope loop 5, and check to ensure reliable locking.

[0036] 3) For example Figure 7 As shown, when the safety rope 6 is in a slack state, the lever 3 is not under force, and the side of the lever 3 closest to the locking rod 7 is lower and the other side is higher. The operator holds the telescopic rod 1 and moves the device upward until the hanging ring 10 extends into the opening of the connecting plate 2. Then, a force F1 is applied downward to the safety rope 6, and the safety rope 6 drives the lever 3 to rotate counterclockwise. During the rotation, the locking rod 7 of the lever 3 enters the open left clamp 9.1 and right clamp 9.2.

[0037] 4) When the electromagnet 9.9 is energized, the left clamp 9.1 and the right clamp 9.2 move upward and close, thus clamping the locking rod 7.

[0038] 5) When a fall occurs, the safety rope 6 is subjected to a downward force, which will continue to pull the left side of the lever 3 downward and the right side of the lever 3 upward. The locking lever 7 continues to press into the locking part 8, causing the left clamp 9.1 and the right clamp 9.2 to clamp the locking lever 7 more tightly to prevent it from coming loose.

[0039] 6) When disassembly is required, the electromagnet 9.9 is de-energized, the left clamp 9.1 and the right clamp 9.2 move down and open, the lever 3 rotates clockwise, the locking rod 7 moves down into place, and the operator holds the telescopic rod 1 and moves the device down so that the hanging ring 10 is finally disengaged from the connecting plate 2.
