Abstract
Description
Technical Field
[0001] The present application relates to the technical field of high-altitude safety equipment, and in particular to a safety walking protection device. Background Art
[0002] When working at height or rock climbing, you need to wear a five-point safety belt, and then put the buckle on the safety belt on the safety rope to maintain a safe connection during movement. The safety rope needs to have a fixed point at every distance. In order to allow the buckle to pass the fixed point without unhooking, it is usually used as shown in the attached Figure 2 The auxiliary structure shown includes an auxiliary wheel 1 and pressure plates 2 on both sides, wherein the pressure plates 2 are used to limit the safety rope from lifting upward, so the buckle is required to carefully pass over the two pressure plates 2 and the auxiliary wheel 1 when passing through. If the safety rope shakes too much, it is easy to break away from the pressure plates 2 or the auxiliary wheel 1, causing the buckle to be disengaged, which is not convenient to use. On the other hand, due to the multi-petal structure of the auxiliary wheel, when the safety rope is suddenly stressed or the auxiliary wheel is hit by external force, individual petals will be deformed, resulting in reduced safety. Utility Model Content
[0003] In order to make up for the above shortcomings, the present application provides a safe walking protection device, which aims to improve the problems mentioned in the above background technology.
[0004] An embodiment of the present application provides a safe walking protection device, including an auxiliary wheel and a mounting piece, the auxiliary wheel being rotatably connected to the mounting piece, a safety rope passing through the auxiliary wheel, a retaining piece being fixedly connected to the mounting piece on the auxiliary wheel, the retaining piece sealing the safety rope inside the auxiliary wheel, the outer circle of the auxiliary wheel movably pressing against the inner wall of the retaining piece, and the front and rear ends of the retaining piece are both arranged in a bell-shaped manner.
[0005] In a specific embodiment, the mounting member includes a support and a rocker arm, the rocker arm is hinged to the support, and a bolt is provided between the rocker arm and the support.
[0006] In a specific embodiment, the auxiliary wheel is rotatably connected to the support.
[0007] In the above implementation process, the rocker arm is passed over the external pole structure and then locked with bolts, which is suitable for installation on artificial equipment. In another embodiment, the mounting member is an anchor bolt for fixing on a cliff.
[0008] In a specific implementation, the positioning member includes a support plate and an inverted U-shaped slot plate, the support plate is fixedly connected to the support, and the slot plate is fixedly connected to the support plate.
[0009] In the above implementation process, the groove plate is used to provide axial support for the periphery of the auxiliary wheel, thereby reducing deformation of the auxiliary wheel and improving reliability.
[0010] In a specific implementation manner, two sides of the auxiliary wheel are respectively attached to the inner wall of the groove plate, and two ends of the groove plate are inclined outwards into a trumpet shape.
[0011] In the above implementation process, when the auxiliary wheel is deformed outward, the auxiliary wheel can easily enter the slot plate through the inclined area during rotation. If the deformation is too large and cannot be rotated into the slot plate, the auxiliary wheel poses a safety hazard and must be replaced. If only one petal cannot pass through, the auxiliary wheel can be reversed first to avoid the deformed petal to allow personnel to pass through, and then the auxiliary wheel can be replaced.
[0012] In a specific embodiment, the inner wall of the slot plate is fixedly connected to a limiting block, and two grooves are formed between two sides of the limiting block and the inner wall of the slot plate for the auxiliary wheels to pass through.
[0013] In a specific embodiment, the limiting block is spindle-shaped.
[0014] In the above implementation process, when a petal deforms inward, the safety rope will be rotated out of the auxiliary wheel during rotation, causing the auxiliary wheel to lose its supporting effect on the safety rope, posing a safety hazard. Here, the limit block and the groove plate play a similar role. When the deformed petal rotates to the limit block, it will be blocked by the limit block, thereby reminding personnel to replace the auxiliary wheel. The spindle-shaped limit block allows smaller deformations to pass.
[0015] In a specific implementation manner, an annular groove adapted to the safety rope is formed in the inner cavity of the auxiliary wheel.
[0016] In the above implementation process, when a person suddenly steps on empty air, the safety rope is pulled downward and sinks into the annular groove. The root of the auxiliary wheel provides support force, thereby avoiding the situation where a petal is deformed due to excessive force, thereby improving the reliability of the auxiliary wheel.
[0017] Compared with the prior art, the beneficial effects of the present application are: the safety rope is sealed in the auxiliary wheel by the blocking piece to prevent the safety rope from being disengaged, thereby improving safety; the blocking piece also provides axial support for the outer circle of the auxiliary wheel, thereby preventing the auxiliary wheel from being severely deformed due to impact, which may lead to the safety rope being disengaged, thereby further improving safety.

[0024] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.
[0025] See also Figure 1-Figure 4 The present application provides a safe walking protection device, including an auxiliary wheel 10 and a mounting member 20, wherein the auxiliary wheel 10 is rotatably connected to the mounting member 20, a safety rope 30 passes through the auxiliary wheel 10, and a retaining member 40 is fixedly connected to the mounting member 20 on the auxiliary wheel 10, wherein the retaining member 40 blocks the safety rope 30 in the auxiliary wheel 10, and the outer circle of the auxiliary wheel 10 is movably pressed against the inner wall of the retaining member 40, and the front and rear ends of the retaining member 40 are both arranged in a bell-shaped configuration. The retaining member 40 is used to block the safety rope 30 in the auxiliary wheel 10, thereby preventing the safety rope 30 from being disengaged, thereby improving safety. The retaining member 40 also provides axial support for the outer circle of the auxiliary wheel 10, thereby preventing the auxiliary wheel 10 from being severely deformed due to impact, thereby preventing the safety rope 30 from being disengaged, thereby further improving safety.
[0026] See also Figure 1-Figure 4The mounting member 20 includes a support 21 and a rocker arm 22, the rocker arm 22 is hinged to the support 21, and a bolt 23 is arranged between the rocker arm 22 and the support 21. The auxiliary wheel 10 is rotatably connected to the support 21. The rocker arm 22 is passed over the external pole structure and then locked with the bolt 23, which is suitable for installation on artificial equipment. In another embodiment, the mounting member 20 is an anchor bolt for fixing on a cliff.
[0027] See also Figure 1-Figure 4 The clamping member 40 includes a support plate 41 and an inverted U-shaped groove plate 42, the support plate 41 is fixedly connected to the support 21, and the groove plate 42 is fixedly connected to the support plate 41. The groove plate 42 is used to provide axial support for the periphery of the auxiliary wheel 10, reduce the deformation of the auxiliary wheel 10, and improve reliability.
[0028] See also Figure 1-Figure 4 The two sides of the auxiliary wheel 10 are respectively attached to the inner wall of the groove plate 42, and the two ends of the groove plate 42 are tilted outward to form a trumpet shape. When the auxiliary wheel 10 is deformed outward, the auxiliary wheel 10 can easily enter the groove plate 42 through the tilted area during rotation. If the deformation is too large and cannot be rotated into the groove plate 42, the auxiliary wheel 10 has a safety hazard and must be replaced. If only one petal cannot pass through, the auxiliary wheel 10 can be reversed first to avoid the deformed petal, allowing people to pass through, and then the auxiliary wheel 10 can be replaced.
[0029] See also Figure 1-Figure 4 The inner wall of the slot plate 42 is fixedly connected to a limit block 43, and two grooves are formed between the two sides of the limit block 43 and the inner wall of the slot plate 42 for the auxiliary wheel 10 to pass through. The limit block 43 is spindle-shaped. When a petal is deformed inward, the safety rope 30 will be rotated out of the auxiliary wheel 10 during the rotation process, so that the auxiliary wheel 10 loses its support for the safety rope 30, posing a safety hazard. Here, the limit block 43 and the slot plate 42 play a similar role. When the deformed petal rotates to the limit block 43, it will be blocked by the limit block 43, thereby reminding the personnel that the auxiliary wheel 10 needs to be replaced. The spindle-shaped limit block 43 allows smaller deformations to pass.
[0030] See also Figure 1-Figure 4 The inner cavity of the auxiliary wheel 10 is provided with an annular groove 50 adapted to the safety rope 30. When a person suddenly steps into the air, the safety rope 30 is pulled downward and sinks into the annular groove 50. The root of the auxiliary wheel 10 provides support force, thereby avoiding the situation where a petal is deformed due to excessive force, and improving the reliability of the auxiliary wheel 10.
[0031] The working principle of the safety walking protection device is: the rocker arm 22 is passed over the external vertical pole structure, and then locked with the bolt 23. It is suitable for installation on artificial equipment. The personnel wear the lock buckle on the safety rope 30 and move. The lock buckle can pass through the auxiliary wheel 10 under the groove plate 42. The safety rope 30 is restricted in the auxiliary wheel 10 by the groove plate 42 and will not be disengaged. When passing by, the personnel can pass through boldly and quickly. It is easy to use. The groove plate 42 also provides axial support from the outer periphery of the auxiliary wheel 10, which improves the structural strength of the auxiliary wheel 10 and improves the reliability. On the other hand, when the auxiliary wheel 10 rotates, the outer ends of all petals will be released from the groove plate 42 and the limit The auxiliary wheel 10 passes through the grooves formed between the blocks 43. When a petal is slightly deformed, it passes through with greater resistance, reminding personnel that the auxiliary wheel 10 needs maintenance. If a petal is greatly deformed, the auxiliary wheel 10 is blocked by the groove plate 42 and the limit block 43 and cannot rotate. In this case, the auxiliary wheel 10 needs to be replaced to eliminate the safety hazard. In summary, the safety rope 30 is blocked in the auxiliary wheel 10 by the blocking member 40 to avoid the safety rope 30 from being disengaged, thereby improving safety. The blocking member 40 also provides axial support for the outer circle of the auxiliary wheel 10, thereby avoiding the auxiliary wheel 10 from being severely deformed due to impact, which in turn causes the safety rope 30 to be disengaged, thereby further improving safety.
