TECHNICAL FIELD
[0001] The utility model belongs to high altitude operation technical field, especially relate to a safety rope hanging device. BACKGROUND
[0002] The safety rope hanging device is an important safety equipment used in high altitude operation, construction, rescue action and other occasions, its main function is to provide stable support and protection for workers, prevent the harm caused by accidental falling. With the development of modern industry and the improvement of people's safety consciousness, the application of safety rope hanging device is more and more widely, and the requirement of its performance and reliability is also higher and higher.
[0003] The existing safety rope hanging device usually includes safety rope, hook and fixing piece and other basic components. The safety rope is the main part of bearing personnel weight, usually made of high-strength fiber material, has good wear resistance, tensile property. The hook is the key component of connecting safety rope and fixed point, its shape and structure design need to meet the requirements of hanging stable, easy to operate. The fixing piece is the component of connecting hook and safety rope, usually adopts bolt, buckle and other forms.
[0004] However, the existing safety rope hanging device still has some deficiencies in practical application. First, in the hanging way, the traditional hook can only adapt to specific hanging hole or hanging rope, for the environment that does not exist these conditions, the hanging process will become difficult even cannot be realized. This limits the use range and flexibility of safety rope hanging device.
[0005] Secondly, the existing safety rope hanging device also has certain hidden danger in safety aspect, when the worker is in high altitude operation, if the safety rope is suddenly tensioned or impacted, the traditional hanging device cannot send alarm.
[0006] Therefore, it is very necessary to invent a safety rope hanging device. CONTENT OF UTILITY MODEL
[0007] The utility model aims at providing a safety rope hanging device, solves the problems mentioned in the background art.
[0008] To solve the above technical problems, the utility model is realized by the following technical schemes:
[0009] This utility model relates to a safety rope attachment device, comprising a connecting frame, a safety rope, a traction rope, a reinforcing frame, a hook, a rocker arm, and a sleeve. The safety rope is fixed inside the connecting frame, and two traction ropes are fixed at one end of the connecting frame. A reinforcing frame is fixed between the traction ropes, and a hook is fixed at the other end of each traction rope. A rocker arm is hinged and rotatably mounted at the notch of the hook, and a sleeve is slidably mounted on the outer side of the hook. The outer side of the rocker arm has an external thread, and the inner wall of the sleeve has an internal thread that matches the external thread.
[0010] Furthermore, the connecting frame includes a frame body, a sliding plate, springs, and a limit switch. Two traction ropes are fixed to the outer side of the frame body, and a sliding plate is slidably installed inside the frame body. Springs are fixed between the two lower sides of the sliding plate and the frame body, and safety ropes are fixed to the outer side of the sliding plate. A limit switch is fixed inside the frame body by bolts, wherein the detection end of the limit switch is located on one side of the sliding plate, and the limit switch is electrically connected to an external alarm device. This arrangement allows the safety rope and the traction rope to be connected, and when the safety rope is in a tensioned state, an alarm can be triggered by the external alarm device.
[0011] Furthermore, the outer surface of the sliding plate is curved, which prevents the sliding plate from scratching the safety rope.
[0012] Furthermore, the reinforcing frame includes a fixing frame and a limiting rope. There are two fixing frames, each fixed to the outer side of the corresponding traction rope. The limiting rope is fixed between the fixing frames. This arrangement can prevent damage to the traction rope.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The design of the traction rope and hook in this utility model enables multiple attachment methods. Regardless of whether there is a hook hole or hook rope in the environment, a suitable attachment method can be found. When there is a hook hole or hook rope, the hook can be directly hooked in. When there is no hook hole or hook rope, the traction rope can be wrapped around the external stable structure and fixed by hook fastening. Furthermore, when the hook is fastened to the hook hole or hook rope and the attachment position needs to be changed, it can be ensured that at least one hook is always connected to the hook rope.
[0015] 2. The connection frame of this utility model is designed such that when a person wearing a safety rope tightens the safety rope, the safety rope can drive the sliding plate to slide inside the frame, thereby making the sliding plate contact the detection end of the limit switch. At this time, the limit switch sends a signal to the external alarm device, which then issues an alarm. Attached Figure Description
