Description

Technical Field

[0001] The utility model relates to the technical field of anti-falling devices, in particular to a guide-type pole tower anti-falling device. Background Art

[0002] A fall prevention device is a device that prevents tower climbers from falling from heights. The main material of a fall prevention device is a guide rail. The guide rail facility is mainly used for positioning and supporting workers at heights during vertical and horizontal displacement, ensuring that workers can move safely and freely within a certain range. According to the different guide rails, fall prevention devices can be divided into: rigid guide rail fall prevention devices and flexible guide rail fall prevention devices. The self-locking device used in the rigid guide rail fall prevention device has a rotatable and retractable buckle inside. When the user moves up and down the ladder normally, the outer end of the buckle is pulled up by the strap, and the buckle inside the self-locking device is retracted so that it can slide freely in the guide rail.

[0003] When an electrician slips during the construction of a pole tower, the electrician will use the strap to pull the buckle in the self-locking device downward to rotate it and quickly buckle the track surface. Due to gravity, the friction between the buckle and the guide rail surface is quickly locked to provide fall protection. However, the self-locking device connecting rope used in the rigid guide rail fall protection device is generally made of low-elasticity textile material. The low-elasticity textile material is mainly used to avoid secondary injuries caused by the rebound of the strap. Therefore, from the time the electrician slips to the time he is lifted up by the strap, the strap does not cushion the impact force generated by the electrician's fall, resulting in a large impact force on the electrician. That is, the self-locking device strap used in the guide rail fall protection device cannot cushion the impact force generated by the electrician's fall. Utility Model Content

[0004] The utility model aims to solve the problem that the self-locking straps used in the guide rail anti-falling device in the prior art cannot buffer the impact force generated by the electrician falling, and proposes a guide tower anti-falling device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A guide-type pole tower anti-fall device, comprising a steel rail, an anti-fall device and a binding belt, wherein the anti-fall device is installed on the steel rail by lifting, the binding belt is installed at the end of a buckle in the anti-fall device, and the binding belt comprises a buffer rope, which is composed of a braided rope, and the braided rope is arranged in a spiral shape and overlapped;

[0007] A plurality of densely arranged rubber strips are fixedly sewn between the upper and lower spirally contacting end surfaces of the braided rope.

[0008] Preferably, a plurality of anti-slip teeth are arranged on the outer end surface of the steel rail, and a plurality of foot nails are fixedly mounted on both sides of the steel rail.

[0009] Preferably, the end of the braided rope is connected to a seat belt speed differential, a winding rope is arranged inside the seat belt speed differential, and the head end of the winding rope is fixedly connected to the end of the braided rope.

[0010] Preferably, the head end of the braided rope is connected to a triangular ring via a connecting rope, and the triangular ring is rotatably mounted on the end of the buckle.

[0011] Preferably, the fall arrester comprises two clamping slides and a fixing plate, the two clamping slides are fixedly mounted on both sides of the fixing plate, a rectangular through hole is provided in the fixing plate, and the buckle is rotatably mounted in the rectangular through hole.

[0012] Preferably, rectangular grooves are provided at both upper and lower ends of the clamping slide plate, pulleys are rotatably installed in four rectangular grooves, and the four pulleys are slidably installed on both sides of the rail respectively.

[0013] Compared with the prior art, the utility model provides a guide-type pole tower anti-falling device, which has the following beneficial effects:

[0014] 1. The guide-type fall prevention device absorbs and weakens the impact force generated by the electrician's fall through the elastic deformation of several rubber strips in the buffer rope, thereby buffering the impact force of the electrician's fall, thereby reducing the damage caused by the impact force to the electrician. In addition, the cross-sectional size of the rubber strip is small. As the electrician falls, the rubber strip can be torn off, reducing the number of rubber strip rebounds and avoiding secondary damage to the electrician caused by the rebound of the rubber strip.

[0015] 2. The guide type anti-fall device is mainly used to increase the friction of the outer end face of the rail through the anti-skid teeth to prevent the buckle from slipping on the anti-skid teeth, so as to provide anti-fall protection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0022] Reference Figure 1-3 A guide-type pole tower anti-fall device comprises a rail 1, the cross section of the rail 1 is T-shaped, a plurality of densely arranged anti-skid teeth 1-1 are arranged on the outer end face of the rail 1, the anti-skid teeth 1-1 are mainly used to increase the friction of the outer end face of the rail 1, and a plurality of equidistantly arranged foot spikes 1-2 are fixedly installed on both sides of the rail 1, the foot spikes 1-2 are mainly used to provide footholds and gripping points for electricians to climb.

[0023] In this embodiment, a fall arrester 2 is installed on the rail 1 for lifting and lowering. The fall arrester 2 includes two clamping slides 2-1 parallel to each other. A fixing plate 2-4 is fixedly connected to the front sides of the two clamping slides 2-1. The fixing plate 2-4 and the outer end surface of the rail 1 are parallel to each other. The fixing plate 2-4 and the clamping slide 2-1 are perpendicular to each other. A certain gap is reserved between the inner end surfaces of the two clamping slides 2-1 and the inner end surfaces of the fixing plate 2-4 and the outer wall of the rail 1, that is, the two clamping slides 2-1 and the fixing plate 2-4 are not in contact with the rail 1, which is mainly used to reduce the friction between the rail 1 and the fall arrester 2, so as to ensure that the fall arrester 2 can move up and down smoothly along the rail 1.

[0024] Rectangular grooves 2-2 are provided at both ends of the clamping slide plate 2-1, and pulleys 2-3 are rotatably installed in the four rectangular grooves 2-2. The four pulleys 2-3 are clamped and installed on both sides of the rail 1 respectively, and the pulleys 2-3 and the rail 1 are contact-type rollingly connected, which is also used to ensure that the fall arrester 2 can move up and down smoothly along the rail 1;

[0025] A rectangular through hole 2-6 is provided on the fixed plate 2-4, and a buckle 2-5 is installed in the rectangular through hole 2-6 by rotating through a rotating shaft. The head end of the buckle 2-5 is crescent-shaped and the tail end is rectangular. The head end of the buckle 2-5 is arranged on the inner side of the rectangular through hole 2-6, and the tail end is arranged on the outer side of the rectangular through hole 2-6. When the tail end of the buckle 2-5 moves upward, the buckle 2-5 rotates counterclockwise with the rotating shaft, thereby driving the tail end of the buckle 2-5 away from the outer end face of the rail 1. When the tail end of the buckle 2-5 moves downward, the buckle 2-5 rotates clockwise with the rotating shaft, thereby driving the tail end of the buckle 2-5 to approach and be squeezed on the anti-slip tooth 1-1 on the outer end face of the rail 1.

[0026] In this embodiment, a strap 3 is rotatably installed at the end of the buckle 2-5, and the strap 3 includes a triangular ring 3-1, a connecting rope 3-2, a buffer rope 3-3 and a seat belt speed differential 3-5. The triangular ring 3-1 is rotatably installed at the end of the buckle 2-5, the head end of the connecting rope 3-2 is fixedly bound to the triangular ring 3-1, the end of the connecting rope 3-2 and the head end of the buffer rope 3-3 are fixedly connected, a winding rope 3-4 is arranged in the seat belt speed differential 3-5, the end of the buffer rope 3-3 and the head end of the winding rope 3-4 are fixedly connected, and the seat belt speed differential 3-5 is bound to the electrician.

[0027] The present application replaces the redundant reserved movable part of the traditional binding belt 3 in the prior art by the winding rope 3-4 in the safety belt speed differential 3-5, which can be extended and retracted according to the distance between the electrician and the rail 1. It is well known that when the safety belt speed differential 3-5 is in normal use, the winding rope 3-4 will freely extend and retract with the human body. Under the action of the locking system in the safety belt speed differential 3-5, it is in a semi-tense state, so that the operator has no sense of worry. In case of slip and fall, the speed of pulling out the safety rope is significantly accelerated, and the locking system in the device is automatically locked, so that the pulling distance of the safety rope does not exceed 0.2 meters, ensuring the safety of the electrician who slips. The work is automatically resumed when the load is released. After the work is completed, the safety rope will be automatically recovered into the device, which is easy to carry.

[0028] It should be added that the buffer rope 3-3 is formed by braided ropes 3-3-1 stacked in a spiral shape, and the braided rope 3-3-1 is specifically made of a textile material with high mechanical strength and low elasticity, such as Figure 3The braided rope 3-3-1 is mainly used to bear the weight of the electrician who has fallen. At the same time, a number of densely arranged rubber strips 3-3-2 are fixedly sewn between the upper and lower spiral contact end surfaces of the braided rope 3-3-1. The rubber strips 3-3-2 are made of rubber material with good elasticity. When the electrician falls, the rubber strips 3-3-2 mainly absorb and weaken the impact force generated by the fall of the electrician through their own elastic deformation, so as to cushion the impact force of the fall of the electrician who has fallen. In addition, the cross-sectional size of the rubber strips 3-3-2 is small. As the electrician falls, the rubber strips 3-3-2 can be torn off, reducing the number of rebounds of the rubber strips 3-3-2 and avoiding secondary damage caused by the rebound of the rubber strips 3-3-2.

[0029] According to the utility model, when the electrician falls, several rubber strips 3-3-2 in the buffer rope 3-3 are stretched in sequence, and the elastic deformation of the rubber strips 3-3-2 is used to absorb and weaken the impact force generated by the electrician's fall, so as to buffer the impact force of the electrician's fall, thereby reducing the damage caused by the impact force to the electrician, and the cross-sectional size of the rubber strips 3-3-2 is small, and the rubber strips 3-3-2 can be torn off as the electrician falls, thereby reducing the number of rebounds of the rubber strips 3-3-2, and avoiding secondary damage to the electrician caused by the rebound of the rubber strips 3-3-2;

[0030] The anti-skid teeth 1-1 are mainly used to increase the friction force on the outer end face of the rail 1 to prevent the buckle 2-5 from slipping on the anti-skid teeth 1-1. When the electrician slips, the electrician will pull the end of the buckle 2-5 downward through the strap 3, so that the buckle 2-5 rotates clockwise about the shaft, thereby driving the end of the buckle 2-5 to approach and squeeze the anti-skid teeth 1-1 on the outer end face of the rail 1. Due to gravity, the buckle 2-5 and the anti-skid teeth 1-1 on the outer side of the rail 1 are quickly locked by friction to provide anti-fall protection.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
