Description

Technical Field

[0001] This utility model relates to the field of safety ladder technology, and in particular to a safety ladder for preventing falls during sluice gate maintenance. Background Technology

[0002] With the continuous expansion of the construction and operation of water conservancy and hydropower projects, sluice gates, as core facilities for regulating water flow, ensuring flood control safety, and rationally allocating water resources, require crucial regular maintenance. Safety ladders, as essential tools for maintenance personnel to reach key parts of the sluice gate, serve as a vital safety barrier in the humid and complex hydraulic work environment, ensuring the smooth conduct of maintenance work. However, their performance and safety directly affect the efficiency of maintenance operations and the safety of personnel; therefore, research on the reliability of safety ladders is receiving increasing attention from the industry.

[0003] The safety ladder for sluice gate maintenance mainly consists of a ladder frame, anti-slip treads, guardrails, and fixing devices. The ladder frame provides stable support, the anti-slip treads have a special textured design to increase friction and prevent slipping, the guardrails surround the ladder to ensure the safety of maintenance personnel when standing and climbing, and the fixing devices can use bolts and clips to firmly connect the safety ladder to the sluice gate structure to prevent shaking.

[0004] In existing technologies, some safety ladders are often unable to cope with complex working conditions due to the humid and narrow spaces at water conservancy operation sites. They lack effective fall protection measures. When maintenance personnel climb and stand to operate, they are prone to losing their balance due to ladder swaying, insufficient anti-slip performance, and missing guardrails, leading to frequent fall accidents. Therefore, the sluice gate maintenance fall-prevention safety ladder is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a safety ladder for sluice gate maintenance, which aims to improve the problem that some safety ladders in the prior art lack fall prevention measures, thus reducing the safety of maintenance personnel.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A safety ladder for sluice gate maintenance includes a vertical frame, an anti-fall mechanism fixedly connected to the outside of the vertical frame, and an adjustment mechanism rotatably connected to the bottom of the vertical frame.

[0008] The fall protection mechanism includes a guide plate, which is fixedly connected to the outside of the vertical frame. A sliding rod is slidably connected inside the guide plate. A connecting plate is fixedly connected to the outside of the sliding rod. A belt is fixedly connected to the outside of the connecting plate. An elastic component is provided inside the vertical frame.

[0009] As a further description of the above technical solution:

[0010] The adjustment mechanism includes a fixed round rod, which is rotatably connected to the outside of the vertical frame. A base is fixedly connected to the outside of the fixed round rod, and a disc is fixedly connected to the outside of the fixed round rod. A limit assembly is fixedly connected to the outside of the vertical frame.

[0011] As a further description of the above technical solution:

[0012] The elastic component includes a guide rod, one end of which is fixedly connected to the inside of the vertical frame, and the other end of which is fixedly connected to a limiting circular plate. A long plate is slidably connected to the outside of the guide rod, and a spring is sleeved on the outside of the guide rod.

[0013] As a further description of the above technical solution:

[0014] One end of the spring is fixedly connected to the inside of the vertical frame, and the other end of the spring is fixedly connected to the outside of the long plate.

[0015] As a further description of the above technical solution:

[0016] The limiting component includes a fixed base, which is fixedly connected to the outside of the vertical frame. A limiting rod is slidably connected inside the fixed base. A pull ring is fixedly connected to the top of the limiting rod, and the bottom of the limiting rod is slidably connected to the inside of the disc.

[0017] As a further description of the above technical solution:

[0018] The vertical frame is fixedly connected to a pedal inside, and the connecting plate is slidably connected to the outer surface of the guide plate.

[0019] As a further description of the above technical solution:

[0020] The external of the vertical frame is fixedly connected to a fixing plate, and the internal of the fixing plate is fixedly connected to a handrail;

[0021] As a further description of the above technical solution:

[0022] The vertical frame is externally fixedly connected to a support plate, and the support plate is internally fixedly connected to a contact rod.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the belt drives the connecting plate, which in turn drives the sliding rod to slide in the vertical groove of the guide plate. When the personnel are not moving, the spring force pushes the long plate to slide along the guide rod, pushing the sliding rod into the inclined groove in the guide plate and locking it in place. This ensures that the operation is not hindered when the personnel are moving normally, and that the system can be locked in time when the personnel are stationary, thereby improving the safety of sluice gate maintenance personnel and reducing the risk of falling.

[0025] 2. In this utility model, by pulling the top ring of the limiting rod, the limiting rod is pulled out from the disc insertion hole, causing the base and disc to rotate around the fixed rod. After adjustment, the limiting rod is inserted again to lock. The angle of the safety ladder can be flexibly adjusted according to actual needs, adapting to different sluice gate maintenance scenarios, enhancing the convenience and flexibility of the safety ladder, and improving the efficiency and stability of maintenance work.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3An embodiment of this utility model is provided: a sluice gate maintenance anti-fall safety ladder, including a vertical frame 1. The vertical frame 1 is the main support structure of the sluice gate maintenance anti-fall safety ladder, and has sufficient strength and stability. An anti-fall mechanism is fixedly connected to the outside of the vertical frame 1, and an adjustment mechanism is rotatably connected to the bottom of the vertical frame 1.

[0034] The fall arrest mechanism includes a guide plate 2, which provides a sliding track for the slide bar 3. The guide plate 2 has a vertical groove and an inclined groove inside. The guide plate 2 is fixedly connected to the outside of the vertical frame 1. The slide bar 3 is slidably connected inside the guide plate 2. The slide bar 3 can be locked in the inclined groove of the guide plate 2 to prevent falling. The slide bar 3 is fixedly connected to the outside of the connecting plate 3. The connecting plate 5 connects the slide bar 3 and the waist belt 6. The waist belt 6 is fixedly connected to the outside of the connecting plate 5. The waist belt 6 is the part that comes into direct contact with the maintenance personnel, making it convenient for the maintenance personnel to put on and take off. The vertical frame 1 has an elastic component inside.

[0035] The elastic component includes a guide rod 7, which provides guidance for the long plate 8, ensuring that the long plate 8 can only move along the axial direction of the guide rod 7. One outer end of the guide rod 7 is fixedly connected to the inside of the vertical frame 1, and the other outer end of the guide rod 7 is fixedly connected to a limiting circular plate 10. The limiting circular plate 10 restricts the range of movement of the long plate 8 on the guide rod 7 and prevents the long plate 8 from detaching from the guide rod 7. The long plate 8 is slidably connected to the outside of the guide rod 7 and can slide on the guide rod 7 under the elastic force of the spring 9, pushing the slide rod 3 into the inclined groove in the guide plate 2. The guide rod 7 is sleeved with a spring 9, which uses its own elastic deformation to store and release energy to push the long plate 8 to slide. One outer end of the spring 9 is fixedly connected to the inside of the vertical frame 1, and the other outer end of the spring 9 is fixedly connected to the outside of the long plate 8.

[0036] Reference Figure 2 and Figure 4 The adjustment mechanism includes a fixed round rod 11, which is the support shaft for the rotation of the base 12 and the disc 13. The fixed round rod 11 is externally rotatably connected to the inside of the vertical frame 1. The base 12 is fixedly connected to the outside of the fixed round rod 11. The base 12 is the part that contacts the safety ladder with the ground and plays the role of supporting the entire safety ladder. The disc 13 is fixedly connected to the outside of the fixed round rod 11. The disc 13 cooperates with the limiting rod 15 to lock and adjust the angle of the safety ladder. The limiting component is fixedly connected to the outside of the vertical frame 1.

[0037] The limiting assembly includes a fixed base 14, which provides an installation base and sliding guide for the limiting rod 15. The fixed base 14 is externally fixedly connected to the outside of the vertical frame 1, and the limiting rod 15 is slidably connected inside the fixed base 14. The main function of the limiting rod 15 is to limit the rotation of the disc 13 by inserting it into the insertion hole of the disc 13, thereby locking the angle of the safety ladder. A pull ring 16 is fixedly connected to the top of the limiting rod 15, which is used to facilitate personnel operation of the limiting rod 15. The bottom of the limiting rod 15 is slidably connected inside the disc 13.

[0038] Reference Figure 2 and Figure 4 The vertical frame 1 has a fixed internal connection to a step 17, which is the part that maintenance personnel step on when going up and down the safety ladder. The step 17 has sufficient load-bearing capacity to support the weight of maintenance personnel. The connecting plate 5 is externally slidably connected to the outer surface of the guide plate 2. The vertical frame 1 has a fixed external connection to a fixing plate 18, which is mainly used to install the handrail 19 and can provide a stable installation foundation for the handrail 19. The fixing plate 18 has a fixed internal connection to the handrail 19, which provides support for maintenance personnel when going up and down the safety ladder, increasing the safety and stability of personnel going up and down the ladder. The vertical frame 1 has a fixed external connection to a support plate 20, which is used to install the contact rod 4. The support plate 20 has a fixed internal connection to the contact rod 4, which is used for contact and engagement operations with the external wall during the maintenance of the sluice gate.

[0039] Working principle: When the sluice gate is under maintenance, the maintenance personnel first put on the waist belt 6 connected to the connecting plate 5. When the personnel move normally on the safety ladder, the slide rod 3 slides in the vertical groove of the guide plate 2. When the slide rod 3 slides in the vertical groove, the slide rod 3 can overcome the elastic force of the spring 9. When the personnel do not move, the elastic force of the spring 9 pushes the long plate 8 to slide along the guide rod 7, pushing the slide rod 3 into the inclined groove in the guide plate 2 and locking it to prevent the slide rod 3 from moving downward, thereby preventing personnel from falling.

[0040] Before using the safety ladder, personnel pull the pull ring 16 at the top of the limit rod 15 to pull the limit rod 15 out of the socket of the disc 13. At this time, the base 12 and the disc 13 can rotate around the fixed rod 11. After adjusting to a suitable angle, the limit rod 15 is inserted into the corresponding socket of the disc 13 through the pull ring 16 to lock the angle of the safety ladder. The contact rod 4 can contact and engage with the external wall to provide support and fixation for maintenance operations. When maintenance personnel go up and down the safety ladder, they step on the footboard 17 and hold the handrail 19 to ensure safety.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
