Description

Technical Field

[0001] The present invention belongs to the technical field of auxiliary tools and relates to a high - climbing safety arrester. Background Art

[0002] Power station operators sometimes need to repair or inspect chimney cooling towers, and the height of the top of some cooling towers can reach nearly 100 meters. If they are not careful, there is a risk of falling. At present, the staff climb the cooling tower by hand. Although the ladder of the cooling tower has been designed in a channel shape, the channel - shaped ladder includes a plurality of footrests and arc - shaped rods connected to the footrests, and the footrests and the arc - shaped rods form a channel, but occasional falling accidents still cannot be avoided. There is an urgent need to invent a simple protective device to avoid falling accidents. Summary of the Invention

[0003] In order to overcome the defects existing in the above - mentioned prior art, the purpose of the present invention is to provide a high - climbing safety arrester to avoid falling accidents.

[0004] The present invention is realized through the following technical solutions:

[0005] A high - climbing safety arrester includes a belt, a waistband, a fork rod and a claw rod. The waistband is connected to both ends of the belt, and the two sections of the waistband are connected by a buckle;

[0006] The fork rod is installed on the belt. The fork rod is hinged to the claw rod, and a torsion spring is installed at the hinge of the fork rod and the claw rod. The fork rod and the claw rod form an elastic included angle;

[0007] The free end of the claw rod is provided with a hook.

[0008] Further, both the belt and the waistband are set as double - loops, and several intermediate belts are connected between the two loops of the belt.

[0009] Further, the fork rod and the claw rod are hinged by a hinge shaft, and the torsion spring is sleeved on the hinge shaft.

[0010] Further, a number of belt holes are opened on the belt, and rivets are installed in the belt holes. One end of the fork rod passes through the rivet and is bent, and after bending, it is wound around the part of the fork rod above the belt.

[0011] Further, one end of the fork rod passes from the inner side plate of the belt to the outside through the rivet.

[0012] Further, the belt is made of cowhide.

[0013] Further, the buckle adopts a metal adjustment buckle.

[0014] Further, the material of the waistband is polypropylene fiber.

[0015] Compared with the prior art, the present invention has the following beneficial technical effects:

[0016] The present invention discloses a climbing safety arrester, which includes a belt, a waistband, a fork rod and a claw rod. The waistband is connected to both ends of the belt, and the two sections of the waistband are connected by a buckle; the fork rod is installed on the belt, the fork rod is hinged to the claw rod, a torsion spring is installed at the hinge of the fork rod and the claw rod, and the fork rod and the claw rod form an elastic included angle; a hook is provided at the free end of the claw rod. The structure is simple, the manufacturing cost is low, and it is convenient for the staff to use. When it is necessary to repair or inspect a chimney cooling tower, the staff needs to climb the ladder on the cooling tower. The waistband is put on the waist of the staff, one side of the buckle is placed in front of the staff, and the belt is placed behind the staff. For each step climbed, since the hook faces inwards, it will not catch the arc-shaped rod of the ladder during the climbing process. When the staff accidentally slips or fails to hold firmly and falls during climbing, the hook catches the ladder, preventing it from falling down, thus achieving the purpose of protecting the maintenance personnel.

[0017] Furthermore, a number of belt holes are opened on the belt, and rivets are installed in the belt holes. One end of the fork rod penetrates through the rivet and is bent, and after bending, it is wound around the part of the fork rod above the belt. This connection structure realizes the connection between the belt and the fork rod. Using rivets as the intermediate connection component, the cost is low and the structure is simple.

[0018] Furthermore, the waistband is made of polypropylene fiber. The raw material source is rich, the production process is simple, the product price is relatively lower than that of other synthetic fibers, and it has high strength, wear resistance and corrosion resistance.

[0020] Figure 2 is Figure 1 a partial enlarged schematic diagram of the connection between the fork rod and the claw rod in

[0021] Wherein: 1 is the belt, 2 is the fork rod, 3 is the claw rod, 4 is the torsion spring, 5 is the waistband, and 6 is the buckle. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following further describes the present invention in detail with reference to the drawings:

[0023] As Figure 1 and 2 shown, the present invention discloses a climbing safety arrester, which includes a belt 1, a waistband 5, a fork rod 2 and a claw rod 3. The waistband 5 is connected to both ends of the belt 1, and the two sections of the waistband 5 are connected by a buckle 6; the fork rod 2 is installed on the belt 1, the fork rod 2 is hinged to the claw rod 3, a torsion spring 4 is installed at the hinge of the fork rod 2 and the claw rod 3, and the fork rod 2 and the claw rod 3 form an elastic included angle; a hook is provided at the free end of the claw rod 3.

[0024] Preferably, both the belt 1 and the waistband 5 are set as double loops, and several intermediate belts 1 are connected between the two loops of the belt 1, making the structure more stable.

[0025] Specifically, the fork rod 2 and the claw rod 3 are hinged by a hinge shaft, and the torsion spring 4 is sleeved on the hinge shaft. The fork rod 2 and the claw rod 3 are opened at a certain angle to form an elastic opening angle.

[0026] The material of the waistband 5 is polypropylene fiber. The raw material source is rich, the production process is simple, the product price is relatively lower than that of other synthetic fibers, it has high strength, and is wear-resistant, corrosion-resistant. The belt 1 and the waistband 5 can also be designed with the same material, such as both being leather or both using woven belts.

[0027] Specifically, a number of belt holes are opened on the belt 1, and rivets are installed in the belt holes. One end of the fork rod 2 passes through the rivet and is bent, and after bending, it is wound around the part of the fork rod 2 above the belt 1.

[0028] One end of the fork rod 2 passes from the inner side plate of the belt 1 to the outside through the rivet, which will not cause discomfort to the human back.

[0029] Specifically, the belt 1 is made of cowhide, and the buckle 6 is a metal adjustment buckle for adjusting the length.

[0030] When maintenance or inspection of the chimney cooling tower is required, the staff needs to climb the ladder on the cooling tower, put the waistband 5 around the waist of the staff, place one side of the buckle 6 in front of the staff, and place the belt 1 behind the staff. For each step climbed, since the hook faces inwards, it will not catch the arc-shaped rod of the ladder during the climbing process. When the staff accidentally slips or fails to hold firmly and falls during the climbing, the hook catches the ladder, preventing it from falling down, achieving the purpose of protecting the maintenance personnel.
