Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a safety belt for chemical pipeline corridor construction. Background Art

[0002] Fall protection harnesses are used when the combined weight of the user and the load they carry does not exceed 100 kg during height work. They are designed to prevent falls and to safely suspend personnel after a fall. Typical height work scenarios include scaffolding, pipe corridors, equipment and pipelines, cable trays, and other areas where workers stand. Fall protection harnesses are typically made of woven tape and metal fittings.

[0003] For example, a construction safety belt hanging device developed by the company with the authorized public number CN220938834U is a fall protection safety belt currently used in the chemical industry. When there is a reliable hanging point on the high working surface, the use of this type of safety belt can achieve the risk control of high-altitude falls for personnel working at fixed points; when high-altitude workers need to move horizontally, it is difficult to have continuous safety belt hanging points available along the entire working route. The existing technology generally requires the pre-setting of a horizontal lifeline on the high-altitude working route, and the horizontal lifeline is used as the hanging point for the safety belt. For example, for high-altitude work on the pipeline corridor of a chemical plant that requires workers to move horizontally, this type of safety belt is difficult to independently meet the use requirements.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figure 1-4As shown, the utility model provides a safety belt for chemical pipeline corridor construction, including a pipeline corridor I-beam 1 and a safety belt 2. The safety belt 2 is provided with a suspension device, which is fixed to the pipeline corridor I-beam 1 to avoid accidents after the worker puts on the safety belt 2. The suspension device includes a connecting ring 3 fixed to the safety belt 2, and the safety belt 2 is easy to disassemble from the connecting ring 3. A rope 4 is provided on the connecting ring 3, and a locking mechanism is provided on the rope 4. A group of pipe clamps 5 are also provided on the rope 4, and the pipe clamps 5 are movably clamped on the pipeline corridor I-beam 1. The locking mechanism is against the bottom of the two pipe clamps 5, so that the pipe clamps 5 are firmly fixed to the pipeline corridor I-beam 1. If a worker wearing the safety belt 2 accidentally falls during operation, the worker can be suspended in mid-air through the connection of the rope 4 and the pipe clamp 5 fixed on the pipeline corridor I-beam 1, and will not fall to the ground.

[0019] The safety belt 2 includes a main belt 6, which is provided with a leg belt 7 and a shoulder belt 8. The main belt 6 is also provided with a waist adjustment buckle 9 and a chest adjustment buckle 10. A buffer hook 11 is provided on the upper part of the main belt 6, a buffer bag 12 is provided on the buffer hook 11, a sling 13 is provided on the buffer bag 12, and a connecting ring 3 is provided on the sling 13.

[0020] The leg straps 7 are located on both sides below the main belt 6 and are provided with metal ring buckles for fixing the leg straps 7 on the main belt 6, and are provided with plastic adjustment buckles for adjusting the fit between the leg straps 7 and the operator's legs.

[0021] The waist adjustment buckle 9 is arranged in the middle position in front of the main belt 6 and consists of a fixed metal ring and a movable metal buckle, which is used to adjust the fit between the waist braided belt and the operator's waist.

[0022] The chest adjustment buckle 10 connects the shoulder straps 8 symmetrically arranged on both sides of the main belt 6. It consists of a fixed metal ring and a movable metal buckle and is used to adjust the fit between the chest braided belt and the operator's chest.

[0023] The shoulder straps 8 connect the main belt 6 and the waist belt, are symmetrically arranged on both sides, and are crisscrossed on the back. They are used to bear the impact of falling from below the neck to above the waist of the operator.

[0024] The buffer hook 11 is made of metal and connects the buffer bag to the fixed metal ring on the back of the main belt. The buffer hook 11 is provided with a bolt knob opening and closing device, which can realize connection and separation with the main belt metal ring.

[0025] The buffer bag 12 is connected in series between the main belt 6 and the hanging point to absorb the impact energy when a person falls. It is made by folding a braided belt and sewing it with a thread of a certain strength.

[0026] There are three clamp locking rings in total, which tighten the two strands of steel rope after the two clamps are fixed into one strand of steel rope, so that the two clamps are firmly fixed on the I-beam steel beam arranged horizontally in the tunnel.

[0027] The locking mechanism includes a locking collar 14, which is threaded with a clamping bolt 15. The rope 4 passes through the inner side of the locking collar 14. There are three or more locking collars 14, and a total of three locking collars 14 are provided. The locking collar 14 is pressed against the bottom of the two pipe clamps 5, and then the clamping bolt 15 is rotated to press the rope 4 against the inner wall of the locking collar 14, so that the locking collar 14 is tightly pressed against the bottom of the pipe clamp 5.

[0028] The pipe wrench 5 includes a handle 16, a limit opening 17 is provided on the embedded handle 16, an adjusting nut 18 is provided in the limit opening 17, and a movable jaw 19 is passed through the handle 16. The position between the handle 16 and the movable jaw 19 is inserted into the steel plate of the pipeline gallery I-beam 1, and then the adjusting nut 18 is rotated to lower the movable jaw 19. The movable jaw 19 and the handle 16 tightly clamp the pipeline gallery I-beam 1. An adjusting bolt 20 is provided on the movable jaw 19. By rotating the adjusting bolt 20, the adjusting bolt 20 is lowered and tightly pressed against the pipeline gallery I-beam 1, so that the pipe wrench 5 is more firmly fixed on the pipeline gallery I-beam 1.

[0029] The working principle of this utility model is as follows:

[0030] The operator's feet enter the two leg straps 7 respectively, and the operator puts the upper limbs through the shoulder straps 8, with the head in the middle of the two shoulder straps 8. The operator tightens the waist adjustment buckle 9 and the chest adjustment buckle 10 to prevent the upper body from loosening from the safety belt 2 during the operator's fall. The operator clamps the movable jaws 19 and the clamp handle 16 tightly to the pipe gallery I-beam 1. The movable jaws 19 are provided with an adjusting bolt 20. By rotating the adjusting bolt 20, the adjusting bolt 20 is lowered and tightly pressed against the pipe gallery I-beam 1, so that the pipe clamp 5 is more firmly fixed on the pipe gallery I-beam 1. Then, the three locking collars 14 are adjusted to press against the bottom of the two pipe clamps 5, and by rotating the clamping bolt 15, the rope 4 is pressed against the inner wall of the locking collar 14 by the clamping bolt 15, so that the locking collar 14 is fixed to the bottom of the pipe clamp 5, so that a pair of pipe clamps 5 are firmly fixed on the pipe gallery I-beam 1 to prevent the pipe clamp 5 from loosening from the pipe gallery I-beam 1. When the operator needs to move horizontally on the pipe gallery, he can use a pair of pipe clamps 5 interchangeably.

[0031] The present invention is simple to operate and easy to use, and is suitable for comprehensive promotion and application.
