Description

Technical Field

[0001] This utility model relates to the technical field of protective equipment for working at heights, and more specifically, to a buffer pack for working at heights. Background Technology

[0002] In gas construction, working at heights is very common, such as the overhead laying of gas pipelines and the roof installation of gas facilities. When gas workers perform such operations, they need to use a protective device that combines safety ropes and cushioning bags to enhance safety.

[0003] Because the length of safety ropes in existing institutions is mostly fixed, the requirements for safety rope length vary greatly depending on the working height and position. Fixed lengths are difficult to adapt. If the rope is too long, it is easy to get tangled or dragged, affecting operation and even causing accidents. If it is too short, it cannot meet the range of work activities, thus affecting the effectiveness of use. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a high-altitude operation buffer pack to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-altitude work cushioning pack includes a cushioning pack, a safety belt fixedly installed on one side of the cushioning pack, a cushioning cavity provided inside the cushioning pack, a polyethylene foam board fixedly installed inside the cushioning cavity, and an adjustment mechanism provided inside the cushioning pack.

[0007] The adjustment mechanism includes a connecting plate fixedly installed on the inner wall of the buffer bag, a rotating shaft rotatably installed at one end of the connecting plate, one end of the rotating shaft passing through the buffer bag and rotatably connected to the buffer bag, a winding roller fixedly installed on the surface of the rotating shaft, a safety rope wound around the surface of the winding roller, and a hand crank fixedly installed at one end of the rotating shaft.

[0008] The surface of the buffer pack has an opening, and multiple fixing rods are fixedly installed on the inner wall of the buffer pack. Guide cylinders are sleeved on the surface of the fixing rods, and the opening is located between the multiple guide cylinders.

[0009] By adopting the above technical solution, the polyethylene foam board in the buffer cavity can effectively absorb the impact of falling, reduce the risk of injury to workers, and make it convenient for workers to flexibly adjust the length of the safety rope to adapt to different working scenarios. At the same time, it ensures that the safety rope can be smoothly retracted and released, avoiding tangling and knotting, and provides comprehensive, convenient and efficient safety protection for working at heights.

[0010] As a further description of the above technical solution: a locking mechanism is provided on one side of the buffer bag, the locking mechanism includes a fixed frame fixedly disposed on one side of the buffer bag, a T-shaped guide block is slidably disposed inside the fixed frame, and a movable plate is fixedly disposed on one side of the T-shaped guide block;

[0011] An electric telescopic rod is fixedly installed on one side of the fixed frame, and a first spike plate is fixedly installed at the output end of the electric telescopic rod. A support block is fixedly installed at the bottom of the fixed frame, and a second spike plate is fixedly installed on one side of the support block.

[0012] By adopting the above technical solution, it can withstand high-intensity tensile force and prevent accidental slippage. Moreover, the T-shaped guide block and the moving plate assist in positioning, ensuring the precise movement of the spikes and improving locking stability. The overall structure is compactly integrated into the buffer bag, which does not affect wearing comfort and portability. It provides reliable, flexible and efficient safety protection for high-altitude operations, effectively reducing operational risks and ensuring personnel safety.

[0013] As a further description of the above technical solution: the end of the safety rope away from the winding roller is fixedly provided with a main lock buckle and an auxiliary safety buckle, and the main lock buckle is located on one side of the auxiliary safety buckle;

[0014] The safety belt may be made of wide, high-strength polyester fiber webbing, and the surface of the safety rope is provided with a polyurethane abrasion-resistant layer.

[0015] By adopting the above technical solution: double locking with main buckle and auxiliary safety buckle, the risk of safety rope falling off is greatly reduced. Moreover, the safety belt made of wide high-strength polyester fiber webbing fits the human body and has strong load-bearing capacity, dispersing tension to avoid local damage. In addition, the polyurethane wear-resistant layer on the surface of the safety rope effectively resists friction, wear and corrosion, and extends service life.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. By setting up an adjustment mechanism, compared with existing technologies, the shaft is controlled by a hand crank to rotate, thereby realizing the winding and unwinding of the safety rope by the winding roller. The operation is simple and intuitive, and operators can quickly master it without complicated training. The length of the safety rope can be flexibly adjusted according to the working position, improving the flexibility of the operation. Secondly, in terms of safety protection, the design of the guide cylinder and the fixed rod effectively prevents the safety rope from getting tangled or knotted during winding and unwinding, avoiding safety hazards caused by the safety rope disorder and ensuring the safety of the operator's life. In addition, the adjustment mechanism has a compact structure and is integrated into the cushioning bag, which does not affect the overall portability and wearing comfort. At the same time, in conjunction with the locking mechanism, the length of the safety rope can be accurately locked, providing reliable and stable safety protection for high-altitude operations, and comprehensively improving the safety and efficiency of the operation.

[0018] 2. By setting up a locking mechanism, compared with the existing technology, it uses an electric telescopic rod to drive the first spike plate, which works in conjunction with the second spike plate to pierce the surface of the safety rope with a spiked structure, achieving a two-way firm lock. It can effectively resist high-intensity tension, prevent the safety rope from slipping accidentally, and greatly reduce the risk of operation. Moreover, in the event of an accidental fall, the locking mechanism can ensure that the safety rope is stably fixed, so that the impact force can be smoothly transmitted to the cushioning material of the cushioning bag, giving full play to the cushioning protection function. The overall structure is compact and integrated into the cushioning bag, which does not affect the overall ease of use, and significantly improves the safety and reliability of working at heights.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] The embodiments disclosed in this application are as follows: Figure 1-5 The high-altitude operation buffer pack shown includes a buffer pack 1, a safety belt 2 fixedly installed on one side of the buffer pack 1, a buffer cavity 3 inside the buffer pack 1, a polyethylene foam board 4 fixedly installed inside the buffer cavity 3, and an adjustment mechanism inside the buffer pack 1.

[0027] The adjustment mechanism includes a connecting plate 5 fixedly installed on the inner wall of the buffer bag 1, a rotating shaft 6 rotatably installed at one end of the connecting plate 5, one end of the rotating shaft 6 passing through the buffer bag 1 and rotatably connected to the buffer bag 1, a winding roller 7 fixedly installed on the surface of the rotating shaft 6, a safety rope 8 wound on the surface of the winding roller 7, and a hand crank 9 fixedly installed at one end of the rotating shaft 6.

[0028] The surface of the buffer bag 1 has an opening 10, and multiple fixing rods 11 are fixedly installed on the inner wall of the buffer bag 1. Guide cylinders 12 are sleeved on the surface of the fixing rods 11, and the opening 10 is located between the multiple guide cylinders 12.

[0029] Depending on the change in work position, the operator controls the rotation direction and number of turns of the rotating shaft 6 by using the hand crank 9. The rotating shaft 6 then drives the take-up roller 7 to perform the winding or unwinding operation. When the hand crank 9 is turned clockwise, the take-up roller 7 winds up the safety rope 8, and when it is turned counterclockwise, the safety rope 8 is unwinded.

[0030] During the deployment and retraction of the safety rope 8, it will pass through multiple guide tubes 12 in sequence. The guide tubes 12 are sleeved on the surface of the fixed rod 11, and the fixed rod 11 is fixed to the inner wall of the buffer bag 1. The guide tubes 12 play a guiding and regulating role, preventing the safety rope 8 from getting tangled or knotted, and ensuring that the safety rope 8 can smoothly pass through the opening 10 and enter and exit the buffer bag 1.

[0031] Reference Figure 2-3 As shown, a locking mechanism is provided on one side of the buffer bag 1. The locking mechanism includes a fixed frame 13 fixedly disposed on one side of the buffer bag 1, a T-shaped guide block 14 slidably disposed inside the fixed frame 13, and a movable plate 15 fixedly disposed on one side of the T-shaped guide block 14.

[0032] An electric telescopic rod 16 is fixedly installed on one side of the fixed frame 13. A first spike plate 17 is fixedly installed at the output end of the electric telescopic rod 16. A support block 18 is fixedly installed at the bottom of the fixed frame 13. A second spike plate 19 is fixedly installed on one side of the support block 18.

[0033] Once the safety rope 8 is adjusted to the appropriate length, the electric telescopic rod 16 is activated. The electric telescopic rod 16 is fixed to one side of the fixed frame 13, and the first spike plate 17 at its output end moves accordingly. The electric telescopic rod 16 extends, pushing the first spike plate 17 toward the safety rope 8. At the same time, the second spike plate 19 on one side of the bottom support block 18 of the fixed frame 13 also moves in coordination. The first spike plate 17 moves toward one side of the safety rope 8 and pierces the surface of the safety rope 8. The spike structure of the first spike plate 17 and the second spike plate 19 is used to firmly lock the safety rope 8, preventing the safety rope 8 from slipping accidentally during operation.

[0034] If the length of the safety rope 8 needs to be adjusted again, the electric telescopic rod 16 is retracted, which drives the first spike plate 17 to retract and release the lock on the safety rope 8. The operator can then readjust the length of the safety rope 8 by hand cranking the handle 9.

[0035] Reference Figure 4-5 As shown, the end of the safety rope 8 away from the winding roller 7 is fixedly equipped with a main locking buckle 20 and an auxiliary safety buckle 21, with the main locking buckle 20 located on one side of the auxiliary safety buckle 21;

[0036] The safety belt 2 can be made of wide, high-strength polyester fiber webbing, and the surface of the safety rope 8 is provided with a polyurethane abrasion-resistant layer 22;

[0037] When a worker accidentally falls, the safety rope 8 will tighten instantly, and the impact force generated by the fall will be transmitted along the safety rope 8 to the buffer pack 1. The polyethylene foam board 4 in the buffer chamber 3 inside the buffer pack 1 will start to play its role, absorbing and dispersing the impact force of the fall, reducing the impact force on the worker's body, reducing the risk of injury, and providing key safety protection for the worker.

[0038] The worker puts on the safety belt 2, which can be made of wide, high-strength polyester fiber webbing to ensure comfortable wear and withstand greater tension. Then, the main lock buckle 20 and auxiliary safety buckle 21 of the safety rope 8 away from the winding roller 7 are firmly connected to the fixed and reliable anchor point for high-altitude operations. The main lock buckle 20 and auxiliary safety buckle 21 provide double protection to prevent the connection from becoming loose.

[0039] Working principle of this utility model:

[0040] This utility model is a high-altitude operation buffer pack. When using this device, the operator wears a safety belt 2, which can be made of wide-width high-strength polyester fiber webbing to ensure comfortable wear and withstand greater tensile force. Then, the main lock buckle 20 and auxiliary safety buckle 21 of the safety rope 8 away from the winding roller 7 are firmly connected to the fixed and reliable anchor point for high-altitude operations. The main lock buckle 20 and auxiliary safety buckle 21 provide double protection to prevent the connection from becoming loose.

[0041] Depending on the change in work position, the operator controls the rotation direction and number of turns of the rotating shaft 6 by using the hand crank 9. The rotating shaft 6 then drives the take-up roller 7 to perform the winding or unwinding operation. When the hand crank 9 is turned clockwise, the take-up roller 7 winds up the safety rope 8, and when it is turned counterclockwise, the safety rope 8 is unwinded.

[0042] During the release and retraction of the safety rope 8, it will pass through multiple guide tubes 12 in sequence. The guide tubes 12 are sleeved on the surface of the fixed rod 11, and the fixed rod 11 is fixed to the inner wall of the buffer bag 1. The guide tubes 12 play a guiding and regulating role, preventing the safety rope 8 from getting tangled or knotted, and ensuring that the safety rope 8 can smoothly pass through the opening 10 into and out of the buffer bag 1.

[0043] Once the safety rope 8 is adjusted to the appropriate length, the electric telescopic rod 16 is activated. The electric telescopic rod 16 is fixed to one side of the fixed frame 13, and the first spike plate 17 at its output end moves accordingly. The electric telescopic rod 16 extends, pushing the first spike plate 17 toward the safety rope 8. At the same time, the second spike plate 19 on one side of the bottom support block 18 of the fixed frame 13 also moves in coordination. The first spike plate 17 moves toward one side of the safety rope 8 and pierces the surface of the safety rope 8. The spike structure of the first spike plate 17 and the second spike plate 19 is used to firmly lock the safety rope 8, preventing the safety rope 8 from slipping accidentally during operation.

[0044] If the length of the safety rope 8 needs to be adjusted again, control the electric telescopic rod 16 to retract, drive the first spike plate 17 to retract, release the lock on the safety rope 8, and the operator can readjust the length of the safety rope 8 by hand cranking the handle 9.

[0045] When a worker accidentally falls, the safety rope 8 will tighten instantly, and the impact force generated by the fall will be transmitted along the safety rope 8 to the buffer pack 1. The polyethylene foam board 4 in the buffer chamber 3 inside the buffer pack 1 will start to play its role, absorbing and dispersing the impact force of the fall, reducing the impact force on the worker's body, reducing the risk of injury, and providing key safety protection for the worker.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
