Description

Technical Field

[0001] The utility model relates to the field of safety protection, in particular to a guide rail type fall arrester. Background Art

[0002] A rail-type fall arrester is a device used for high-altitude working safety, usually composed of components such as rails, sliders and connecting devices. Its working principle is that when a worker falls from a height, the fall arrester can be quickly fixed on the rail, thereby reducing or avoiding injuries to the worker. A rail-type fall arrester is usually installed on high-altitude working platforms or suspended working equipment to provide additional safety protection for workers. The use of a rail-type fall arrester can effectively reduce the risk of falling accidents during high-altitude operations and protect the lives of workers.

[0003] The traditional installation method of the guide rail type fall arrester is to slide the fall arrester into the port at the bottom or top of the guide rail, and it cannot be expanded horizontally. The installation is very inconvenient, time-consuming and labor-intensive. When both ends of the guide rail are fixed, the fall arrester cannot be installed. The traditional guide rail type fall arrester is limited. Therefore, a guide rail type fall arrester is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a guide rail fall arrester, comprising a main body 1, two limit rods 2 are slidably connected to the right side of the front of the main body 1, a sub-body 3 is fixedly connected between the right ends of the two limit rods 2, a safety bolt 4 is fixedly connected to the front side of the top of the sub-body 3, a safety buckle 5 is rotatably connected to the right side of the top of the main body 1, rollers 6 are rotatably connected to the upper and lower sides of the main body 1 and the sub-body 3, a pull rod 7 is slidably connected to the right side of the bottom of the main body 1, a baffle 8 is fixedly connected to the upper side of the outside of the pull rod 7, a spring 9 is fixedly connected to the bottom of the baffle 8, a shell 10 is rotatably connected to the inside of the front side of the main body 1, a gate plate 11 is fixedly connected to the rear side of the shell 10, a buffer component is installed inside the shell 10, the safety buckle 5 and the safety bolt 4 are engaged, the spring 9 is internally sleeved on the outside of the pull rod 7, the bottom end of the spring 9 is fixedly connected to the inner bottom wall of the main body 1, the outer periphery of the baffle 8 is slidably connected to the inner wall of the main body 1, and the pull rod 7 is inserted into the limit rod 2.

[0032] Specifically, the main body 1 and the sub-body 3 cooperate to clamp the entire device on the guide rail. The limit rod 2 is used to limit the movement direction of the sub-body 3 to ensure the stability of the sub-body 3 and prevent it from moving around. The safety buckle 5 is a buckle that is engaged on the safety pin 4 to prevent accidental touching of the pull rod 7 to unlock the sub-body 3 during high-altitude operations. When the safety pin 4 and the safety buckle 5 are in the engaged state, even if the pull rod 7 is pulled out, the sub-body 3 will not be unlocked. The roller 6 is used to allow the entire fall arrester to move smoothly on the guide rail. The pull rod 7 and the limit rod 2 cooperate to fix the sub-body 3. When the pull rod 7 is pulled, the baffle 8 will compress the spring 9. As long as the hand pull rod 7 is released, the spring 9 will push the baffle 8 to pop out the pull rod 7 and reset it. The housing 10 is used to connect and protect the buffer assembly, and the gate 11 is used to resist the guide rail to achieve fall prevention.

[0033] Reference Figure 1 , Figure 4 , Figure 5 The buffer assembly includes a steel cable 12, the outside of the steel cable 12 is slidably connected to the inside of the front side of the shell 10, the outside of the steel cable 12 is fixedly connected to two baffle plates 13, the rear side of the left baffle plate 13 is fixedly connected to a spring 14, the front side of the measured baffle plate 13 is fixedly connected to the rear end of another spring 14, the rear end of the left spring 14 is fixedly connected to a fixing plate 15, a guide wheel 17 is arranged on the outside of the steel cable 12, a lock buckle 16 is fixedly connected to the front end of the steel cable 12, the outer periphery of the fixing plate 15 is fixedly connected to the inner wall of the shell 10, the outside of the steel cable 12 is slidably connected to the left and right sides of the fixing plate 15, the baffle plate 13 is slidably connected to the inner wall of the shell 10, the upper and lower ends of the guide wheel 17 are rotatably connected to the inner wall of the shell 10, the spring 14 is internally sleeved on the outside of the steel cable 12, and the front end of the right spring 14 is fixedly connected to the front side of the inner wall of the shell 10.

[0034] Specifically, the steel cable 12 is a soft steel rope that can easily bear hundreds of pounds. The baffle 2 13 is fixed on the steel cable 12. When the steel cable 12 is subjected to force, the baffle 2 13 will compress the spring 2 14 to achieve buffering. The fixing plate 15 is used to fix the left spring 2 14 so that the left spring 2 14 has a force point. The guide wheel 17 is used for the steel cable 12 to turn smoothly inside the shell 10, driving the baffle 2 13 to compress the spring 2 14. The lock buckle 16 is used to facilitate the fixation of the safety rope tied to the worker's body.

[0035] Working principle: when it is necessary to work at high altitude, first push the safety buckle 5 outward to disengage the safety buckle 5 from the safety pin 4 to open the safety, and then pull the pull rod 7, the pull rod 7 will be pulled out from the limit rod 2, and the auxiliary body 3 will be pulled out under the limit of the limit rod 2, and then the whole device is placed on the guide rail, and the main body 1 and the auxiliary body 3 are squeezed to merge them, and the spring 19 pushes the baffle 18 to drive the pull rod 7 to insert into the limit rod 2 until a "click" sound is heard, indicating that it is locked, and then push the safety buckle 5 back to re-engage the safety buckle 5 and the safety pin 4 to re-lock the safety, and then you can start working at high altitude. When you accidentally fall at high altitude due to slipping, the safety rope pulls the shell 10 because the human body descends faster than the fall arrester. The shell 10 lifts the gate 11 against the guide rail and locks it directly. The safety rope drives the lock buckle 16 to pull the steel cable 12, and the steel cable 12 pulls the baffle 13 to compress the spring 14 to achieve buffering and stop the worker from falling.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
