Description

Technical Field

[0001] The utility model relates to the technical field of fall arresters, in particular to an anti-derailment type flexible guide rail fall arrester. Background Art

[0002] A guide rail fall arrester is a safety device used to prevent people or objects from falling from heights. The function of a guide rail fall arrester is to provide additional safety protection, especially when working or doing activities at heights. It can prevent people from accidentally falling and reduce the risk of injury. Guide rail fall arresters are usually used in construction sites, high-altitude operations, stage performances and other occasions to ensure the safety of workers and audiences.

[0003] Conventional guide rail fall arresters typically consist of a guide rail, a guide rail slider, and a safety lock. The guide rail is typically installed at a high location, such as the edge of a building or next to a staircase. The guide rail slider slides freely on the rail and contains a safety lock installed inside. If a person or object falls, the safety lock automatically locks, preventing further falls.

[0004] However, when some guide rail fall arresters are in use, most of them are connected to the flexible rail through a locking slider. If the device is to be in the best operating state at all times, workers need to regularly maintain the flexible guide rail to ensure that there are no large impurities adhering to the surface of the flexible guide rail, because some large impurities may cause the locking slider to slip, so there cannot be some large impurities on the surface of the flexible guide rail. Flexible guide rails are generally set at a relatively high position, so each time the guide rails are maintained, a lot of time and energy are required. Therefore, an anti-derailment flexible guide rail fall arrester is proposed to solve the above problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes an anti-derailment flexible guide rail anti-fall device. Through the provided cleaning mechanism, the flexible guide rail body can be automatically cleaned during use to avoid large impurities adhering to the surface and affecting the locking effect.

[0006] The technical solution for achieving the purpose of the utility model is: an anti-derailment flexible guide rail anti-fall device, comprising a front main cover and a rear main cover, the inner walls of the front main cover and the rear main cover are respectively rotatably connected with an upper locking block and a lower locking block through two pin shafts, the surfaces of the upper locking block and the lower locking block are respectively provided with protrusions, the surfaces of the upper locking block and the lower locking block are respectively rotatably connected with two connecting plates through two pin shafts, the upper locking block and the lower locking block are arranged in the space formed between the two connecting plates, the end of the lower locking block is provided with a through hole, the inner wall of the through hole is provided with a quick connecting ring, a locking port is formed between the front main cover and the rear main cover, and a flexible guide rail body is provided inside the locking port.

[0007] In some embodiments, the upper surfaces of the front main cover and the rear main cover are fixedly connected to the front connection cover and the rear connection cover respectively, a rectangular groove is opened on one side of the front connection cover, and a rectangular frame is fixedly connected to the inner wall of the rectangular groove.

[0008] In some embodiments, two limiting grooves are formed on the inner wall of the rectangular frame, the inner walls of the two limiting grooves are slidably connected to limiting blocks, and the opposite surfaces of the two limiting blocks are fixedly connected to the same slide.

[0009] In some embodiments, a plurality of springs 2 are fixedly connected to one side of the slide, an end of the plurality of springs 2 away from the slide is fixedly connected to the inner wall of the rectangular frame, and a plurality of trapezoidal blocks are fixedly connected to the side of the slide away from the springs 2.

[0010] In some embodiments, two sliding grooves are provided on one side of the slide, the inner walls of the two sliding grooves are fixedly connected to fixed rods, the surfaces of the two fixed rods are slidably connected to sliders, one side of the two sliders is fixedly connected to spring 1, the ends of the two spring 1s away from the sliders are respectively fixedly connected to the inner walls of the corresponding two sliding grooves, the two spring 1s are respectively mounted on the surfaces of the two fixed rods, and one side of the two sliders is fixedly connected to the same brush plate.

[0011] Compared with the prior art, the present invention has the following significant advantages:

[0012] First, the utility model uses the rectangular frame on the front connecting cover and the slide plate arranged inside the rectangular frame to rise synchronously, so that the brush plate on the slide plate can clean the surface of the flexible guide rail body and remove large particles of impurities on the surface of the flexible guide rail body. During the rising process, the trapezoidal block slides on the surface of the flexible guide rail body. The flexible guide rail body is a steel wire rope, and the surface of the steel wire rope is uneven, which will continuously squeeze the trapezoidal block. Under the action of the second spring, the slide plate will vibrate back and forth laterally inside the rectangular frame, thereby improving the cleaning ability of the brush plate on the surface of the flexible guide rail body.

[0013] Secondly, during the upward process, the utility model lifts the locking block by pulling the quick connecting ring, and the upward movement is smooth and unobstructed. When a fall occurs, the quick connecting ring is quickly pulled down due to the instantaneous gravity. Due to the principle of the four-linkage of the Quyou slider, the upper locking block and the lower locking block are immediately locked with the wire rope, thereby protecting people's lives.

[0014] The invention solves the problem that the existing flexible guide rails are generally arranged at a relatively high position, so each time the guide rails are maintained, a lot of time and energy are required. BRIEF DESCRIPTION OF THE DRAWINGS

When the anti-fall device is installed on the flexible guide rail body 8, the hole of the connecting ring interferes with the connecting plate 5, so that the anti-fall device can no longer be lifted, and the protrusion 11 part cannot be retracted inside, preventing the wire rope from coming out of the notch of the main cover, thereby protecting the safe use of the anti-fall device, a locking port 12 is formed between the front main cover 1 and the rear main cover 2, and the flexible guide rail body 8 is provided inside the locking port 12.

[0026] like Figure 4 As shown, in one embodiment, the upper surfaces of the front main cover 1 and the rear main cover 2 are fixedly connected with the front connecting cover 7 and the rear connecting cover 14 respectively, a rectangular groove is opened on one side of the front connecting cover 7, and the inner wall of the rectangular groove is fixedly connected with a rectangular frame 15, and the cleaning mechanism is arranged inside the rectangular frame 15.

[0027] like Figure 4 and Figure 5 As shown, in one embodiment, two limit grooves 23 are provided on the inner wall of the rectangular frame 15, and the inner walls of the two limit grooves 23 are slidably connected to the limit blocks 24. The opposite surfaces of the two limit blocks 24 are fixedly connected to the same slide 16. The setting of the limit grooves 23 and the limit blocks 24 can improve the stability of the slide 16 when the slide 16 vibrates laterally.

[0028] One side of the slide 16 is fixedly connected to a plurality of springs 22, and one end of the plurality of springs 22 away from the slide 16 is fixedly connected to the inner wall of the rectangular frame 15. The side of the slide 16 away from the springs 22 is fixedly connected to a plurality of trapezoidal blocks 13. There are several trapezoidal blocks 13, which are distributed in a vertical linear array on the slide 16 and can adapt to the thread shape of the surface of the wire rope, thereby forming reciprocating vibration.

[0029] Two slide grooves 18 are provided on one side of the skateboard 16, and the inner walls of the two slide grooves 18 are fixedly connected with fixed rods 19, and the surfaces of the two fixed rods 19 are slidably connected with sliders 20.

[0030] The specific working method is: in the process of vertical climbing, in order to prevent people from accidentally falling, a flexible guide rail, namely a wire rope and a fall arrester are specially set; first, turn the fall arrester sideways 90 degrees, with the notch facing the flexible guide rail, snap it in, and then turn it 90 degrees along the direction of the guide rail, put on the quick connection ring 6 to prevent derailment, and use it upward. The disassembly method is the reverse process of the installation method; the principle of the fall arrester is that during the upward process, the locking block is lifted by pulling the quick connection ring 6, and the upward movement is smooth and unobstructed. When a fall occurs, due to the instantaneous gravity, the quick connection ring 6 is quickly pulled down, and due to the principle of the four-link slider 20, the upper locking block 3 and the lower locking block 4 are immediately locked with the wire rope, thereby protecting people's lives.

[0031] During the upward process, the rectangular frame 15 on the front connecting cover 7 and the slide 16 arranged inside the rectangular frame 15 rise synchronously, so that the brush plate 17 on the slide plate 16 can clean the surface of the flexible guide rail body 8 and remove large particles of impurities on the surface of the flexible guide rail body 8. During the upward process, the trapezoidal block 13 slides on the surface of the flexible guide rail body 8. The flexible guide rail body 8 is a steel wire rope. The surface of the steel wire rope is uneven, which will continuously squeeze the trapezoidal block 13. Under the action of spring 22, the slide plate 16 will vibrate back and forth laterally inside the rectangular frame 15, thereby improving the cleaning ability of the brush plate 17 on the surface of the flexible guide rail body 8. The set slide groove 18, slider 20 and spring 1 21 can ensure that the brush plate 17 always fits with the surface of the flexible guide rail body 8.
