Description

Technical Field

[0001] This utility model relates to the field of water conservancy construction engineering technology, and in particular to a fall prevention device for high-altitude operations in water conservancy construction engineering. Background Technology

[0002] Working at heights generally refers to work performed at a height relative to a certain position. In the construction industry, the scope of working at heights is quite extensive. When working inside a building, if the operation is carried out on scaffolding more than two meters high, it is considered working at heights and appropriate safety measures must be in place.

[0003] Existing fall protection devices for high-altitude operations mostly use a method of directly fixing safety ropes. This method cannot adjust and fix the length of the safety rope in a timely manner as needed in different construction environments, making it inconvenient to use. Furthermore, the fall cushioning relies on a single rope, and excessive impact force can easily cause secondary injuries. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a fall protection device for high-altitude operations in water conservancy construction projects.

[0005] An embodiment of this utility model provides a fall protection device for high-altitude operations in water conservancy construction engineering, comprising:

[0006] A base plate, on which a buffer assembly is mounted, and a fixed plate is mounted on the buffer assembly. A support frame is fixedly connected to the upper end face of the fixed plate. Two take-up rollers are mounted on the support frame. Each of the two take-up rollers is equipped with an anti-fall assembly. The anti-fall assembly includes a fixed cylinder fixedly connected to the side wall of the take-up roller, a connecting rod slidably connected inside the fixed cylinder, a first spring fixedly connected to the inner wall of the fixed cylinder, a counterweight fixedly connected to the connecting rod, and a fixed ring fixedly connected to the take-up roller. The fixed plate... A fixed frame is fixedly connected to the upper end face, and a mounting frame is fixedly connected to the fixed frame. The mounting frame has a limit groove and a lifting groove. A second spring is fixedly connected to the inner wall of the lifting groove. A toggle rod is slidably connected to the lifting groove. The toggle rod is fixedly connected to the second spring. A locking block is slidably connected to the inner wall of the limit groove. A third spring is fixedly connected to the limit groove. The third spring is fixedly connected to the locking block. A locking groove is opened on the locking block. The toggle rod slides through the mounting frame and matches the locking groove. Multiple baffles are fixedly connected to the inner wall of the fixed ring.

[0007] Furthermore, a plurality of fourth springs and dampers are fixedly connected to the upper surface of the base plate, with each of the fourth springs corresponding to one of the dampers. A plurality of guide rods are fixedly connected to the upper surface of the base plate, and each of the guide rods slides through the fixed plate. The fixed plate is fixedly connected to the plurality of fourth springs, and the plurality of dampers are fixedly connected to the fixed plate.

[0008] Furthermore, multiple fixing bolts slide through the base plate, and multiple wire-passing holes are opened on both the fixing plate and the base plate. Steel cables are provided on both of the two winding rollers, and lifting rings are fixedly installed on both of the steel cables.

[0009] Furthermore, a dual-axis motor is installed on the support frame, and both take-up rollers are rotatably connected to the support frame. The rotating ends of the dual-axis motor are respectively fixedly connected to the two take-up rollers.

[0010] Furthermore, two sets of uprights are fixedly connected to the upper end face of the fixing plate. The uprights are in pairs, and a support ring is fixedly connected to each set of uprights. The fixing ring is rotatably connected to the inner wall of the support ring.

[0011] Furthermore, the lower end surface of the base plate is provided with anti-slip texture.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. In the event of an accident, the winding roller rotates faster. Under the action of centrifugal force, the first spring extends, and the counterweight will hit the actuating rod, causing the actuating rod to move upward. Then the third spring returns to its original position, pushing out the locking block. The locking end of the locking block, together with the baffle, limits the fixed ring, thereby limiting and fixing the winding roller, ensuring the safety of personnel during construction.

[0014] 2. By setting a fourth spring in conjunction with a damper, the impact force during a fall is buffered, reducing the damage to construction workers and improving the safety of the device. Attached Figure Description

Detailed Implementation

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a fall protection device for high-altitude operations in water conservancy construction projects, comprising:

[0021] The base plate 1 has anti-slip textures on its lower end surface to improve the stability of the device. A buffer assembly is installed on the base plate 1, and a fixed plate 2 is installed on the buffer assembly. A support frame 3 is fixedly connected to the upper end surface of the fixed plate 2. A dual-axis motor 17 is installed on the support frame 3. Two take-up rollers 4 are rotatably connected to the support frame 3. The rotating ends of the dual-axis motor 17 are respectively fixedly connected to the two take-up rollers 4. Two take-up rollers 4 are installed on the support frame 3. Multiple fixing bolts 18 slide through the base plate 1. Multiple cable passages are opened on both the fixed plate 2 and the base plate 1. Steel cables are provided on both take-up rollers 4. The steel cables are located inside the cable passages. Hanging rings are fixedly installed on both steel cables for easy user operation. Anti-fall components are installed on both take-up rollers 4.

[0022] The anti-fall assembly includes a fixed cylinder 5 fixedly connected to the side wall of the take-up roller 4, a connecting rod 6 slidably connected inside the fixed cylinder 5, a first spring 7 fixedly connected to the inner wall of the fixed cylinder 5, a counterweight fixedly connected to the connecting rod 6, a fixed ring 8 fixedly connected to the take-up roller 4, a fixed frame 9 fixedly connected to the upper end face of the fixed plate 2, a mounting frame 10 fixedly connected to the fixed frame 9, a limit groove and a lifting groove on the mounting frame 10, a second spring 11 fixedly connected to the inner wall of the lifting groove, a toggle rod 12 slidably connected inside the lifting groove, a toggle rod 12 fixedly connected to the second spring 11, a locking block 13 slidably connected to the inner wall of the limit groove, a third spring 14 fixedly connected inside the limit groove, a locking block 13 fixedly connected to the locking block 13, a locking groove on the locking block 13, a toggle rod 12 slidably passing through the mounting frame 10 and matching the locking groove, and multiple baffles 15 fixedly connected to the inner wall of the fixed ring 8.

[0023] Multiple fourth springs and dampers 16 are fixedly connected to the upper end face of the base plate 1. Each of the multiple fourth springs corresponds to one of the multiple dampers 16. Multiple guide rods 20 are fixedly connected to the upper end face of the base plate 1. The multiple guide rods 20 slide through the fixed plate 2. The fixed plate 2 is fixedly connected to the multiple fourth springs. The multiple dampers 16 are fixedly connected to the fixed plate 2. Two sets of uprights are fixedly connected to the upper end face of the fixed plate 2. The uprights are in pairs. Each set of uprights is fixedly connected to a support ring 19. The fixed ring 8 is rotatably connected to the inner wall of the support ring 19 to support the winding roller 4 and improve the stability of the winding roller 4 rotation.

[0024] The detailed working process of this utility model is as follows:

[0025] The device is fixed in the designated position using fixing bolts 18. When the steel cable needs to be lowered, the dual-axis motor 17 starts working, driving the take-up roller 4 to rotate. The dual-axis motor 17 controls the two ropes respectively. If one axis fails, the other axis can still maintain load stability through emergency braking, improving safety. In case of an accident, the rotation speed of the take-up roller 4 increases. Under the action of centrifugal force, the first spring 7 in the fixed cylinder 5 extends, the connecting rod 6 slides in the fixed cylinder 5, and the counterweight will hit the actuating rod 12, causing the second spring 11 to contract. The actuating rod 12 moves upward and moves out of the locking groove. Then the third spring 14 resets, pushing the locking block 13 out of the limiting groove. The locking end of the locking block 13 cooperates with the baffle 15 on the fixed ring 8 to limit the fixed ring 8, thereby limiting and fixing the take-up roller 4, ensuring the safety of personnel during construction. After the take-up roller 4 is limited, the fourth spring is set in conjunction with the damper 16 to buffer the impact force when falling, reducing the impact force on construction personnel and further improving the safety of the device.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
