Abstract
Description
Technical Field
[0001] This utility model belongs to the field of high-altitude operation technology, and in particular relates to a safety fall prevention device. Background Technology
[0002] In high-altitude operations, the safety of workers is the primary concern. While traditional fall protection devices offer some protection, they still have limitations in practical use. For example, some devices may be difficult to operate during climbing due to their complex design, increasing the psychological and physical burden on workers.
[0003] In view of the shortcomings of the existing technology, this utility model provides a safety fall prevention device, which aims to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a safe fall protection device that is simple in design and convenient for high-altitude workers to operate.
[0005] To achieve the above objectives, this utility model employs the following technical solution:
[0006] A safety fall arrest device includes a flexible guide rail, multiple fall arrest blocks, and multiple telescopic mechanisms;
[0007] The anti-fall blocks are symmetrically arranged on the outer periphery of the flexible guide rail, and the inner side of the anti-fall blocks near the flexible guide rail is arc-shaped, the inner diameter of the arc being the same as the outer diameter of the flexible guide rail; two sides adjacent to the inner side of the anti-fall blocks are provided with rectangular grooves, and two fixed shafts are provided in the rectangular grooves.
[0008] The telescopic mechanism is movably connected to the fall arrestor block and is used to change the distance between two adjacent fall arrestor blocks.
[0009] Preferably, the telescopic mechanism includes a pair of rotating rods connected by a rotating shaft, and both ends of the rotating rods are rotatably connected to a fixed shaft mounted on the fall arrestor block.
[0010] Preferably, the rotating rod has a guide channel for guiding the safety rope through, and the connection end of the safety rope near the ground is connected to the worker working at height.
[0011] Preferably, the inner side of the anti-fall block near the outer periphery of the flexible guide rail is also connected to an anti-slip engaging component.
[0012] Preferably, the anti-slip fastener has a serrated shape.
[0013] Preferably, there are four of each of the anti-fall blocks and telescopic mechanisms.
[0014] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:
[0015] 1. This utility model combines four telescopic mechanisms with four fall arresting blocks. The telescopic mechanism includes a pair of rotating rods connected by a rotating shaft. This structure allows the distance between the fall arresting blocks to be adjusted as needed. The two ends of the rotating rods are rotatably connected to a fixed shaft installed on the fall arresting blocks. The rotating rods have guide channels for guiding the safety rope through, and the end of the safety rope near the ground is connected to the worker at height. When the worker at height accidentally falls, the bottom of the safety rope will be subjected to a rapid downward force. This force causes the pair of rotating rods to quickly move closer together, and then the fall arresting blocks will quickly move towards the flexible guide rail and clamp it, achieving the effect of preventing a fall.
[0016] 2. This utility model provides an anti-slip engaging component on the inner side of the anti-fall block near the flexible guide rail, and the anti-slip engaging component is serrated in shape. This can increase the friction and gripping force between the anti-fall block and the flexible guide rail, and prevent the anti-fall block from accidentally sliding on the flexible guide rail when it falls.

[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.
[0023] In the description of this utility model, it should be understood that the terms "middle," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0025] refer to Figures 1-3 This embodiment provides a safety fall arrest device, including a flexible guide rail 1, multiple fall arrest blocks 2 and multiple telescopic mechanisms 3;
[0026] The fall arresting blocks 2 are symmetrically arranged on the outer periphery of the flexible guide rail 1, and the inner side of the fall arresting blocks 2 near the flexible guide rail 1 is arc-shaped, the inner diameter of the arc shape is the same as the outer diameter of the flexible guide rail 1; two sides adjacent to the inner side of the fall arresting blocks 2 are provided with rectangular grooves 21, and two fixed shafts 22 are provided in the rectangular grooves 21.
[0027] Specifically, there are four of each of the anti-fall blocks 2 and the telescopic mechanism 3.
[0028] The telescopic mechanism 3 is movably connected to the fall arrestor block 2 and is used to change the distance between two adjacent fall arrestor blocks 2. The telescopic mechanism 3 includes a pair of rotating rods 31, which are connected by a rotating shaft 33, and both ends of the rotating rods 31 are rotatably connected to a fixed shaft 22 installed on the fall arrestor block 2.
[0029] Furthermore, the rotating rod 31 has a guide channel 32 for guiding the safety rope 4 through, and the connection end of the safety rope 4 near the ground is connected to the high-altitude worker.
[0030] In this embodiment, the safety rope 4 is threaded in the following way:
[0031] One end of the safety rope 4 is passed from bottom to top through the guide channel 32 of one rotating rod 31, and then from top to bottom through the guide channel 32 of another rotating rod 31. Finally, the two ends of the safety rope 4 are tied at the bottom (the end closest to the ground). According to this embodiment, there should be four knots, and the ends of the safety rope 4 at the four knots are all connected to the safety harness around the waist of the worker at height.
[0032] In order to increase the friction between the anti-fall block 2 and the flexible guide rail 1 and prevent the anti-fall block 2 from accidentally sliding on the flexible guide rail 1 when it falls, in this embodiment, the inner side of the anti-fall block 2 near the outer periphery of the flexible guide rail 1 is also connected to an anti-slip fastener 5. In this embodiment, the anti-slip fastener 5 is set in a serrated shape.
[0033] Working principle: Under normal circumstances, the worker's feet are on the foot spikes. In this design, the worker's waist is connected to the bottom of the safety rope 4. When moving slowly upwards, the safety rope 4 is in a relaxed state, and the telescopic mechanism 3 and the fall arrestor 2 are also detached from the flexible guide rail 1. When the worker accidentally falls, the fall arrestor 2 will remain unchanged due to inertia, while the bottom of the safety rope 4 will be subjected to a rapid downward force. This force causes a pair of rotating rods 31 to quickly approach each other, and then the fall arrestor 2 will quickly approach the flexible guide rail 1 and clamp it, achieving the effect of preventing a fall. In addition, the inner part of the fall arrestor 2 near the flexible guide rail 1 is also equipped with an anti-slip locking part 5, which further reduces the risk of falling.
[0034] It should be noted that the flexible guide rail 1 is usually made of steel strand or similar flexible material, so it can be clamped by the above-mentioned anti-fall block 2, telescopic mechanism 3 and serrated anti-slip clamp 5 to achieve the purpose of preventing falls.
[0035] In summary, this utility model, through its simple structural design, makes it easier for workers at heights to operate and can prevent them from falling due to slips while working.
[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
