Description

Technical Field

[0001] This utility model relates to the field of safety railing technology, and in particular to a safety protection device for long-distance, steep-slope corridors. Background Technology

[0002] In the construction of coal-fired power plant projects or mining and metallurgical projects, belt conveyor corridors are built. These corridors are specialized channels for transporting bulk materials such as coal and ore, and are characterized by long distances and steep gradients. Throughout the project construction process, it is common to see manual material handling or walking on these long, steep belt conveyor corridors, and the higher the altitude, the more tiring it becomes for workers.

[0003] To ensure personnel safety, guardrails are typically installed on both sides of the conveyor belt. However, in the event of a slippage accident, people or objects will accelerate downwards along the conveyor belt under the influence of gravity. Without timely and effective restraints, the rolling speed will gradually increase, potentially causing serious injuries. Currently, there is a lack of mature safety protection devices specifically designed for this purpose, making the deployment of safety protection facilities during construction on long-distance, steep-slope conveyor belt corridors extremely difficult. Summary of the Invention

[0004] To address the problem that conventional guardrails are unable to respond promptly to slippage accidents, this utility model provides a safety protection device for long-distance, steep-slope corridors. Several telescopic guardrails are staggered along the length of the corridor, and the unfolded length of the telescopic guardrails is adapted to the width of the corridor, so as not to affect the movement of people and the handling of materials, while providing timely safety protection.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A safety protection device for a long-distance, steep-slope corridor includes several telescopic guardrails, which are arranged along the length of the corridor to facilitate protection of the entire length of the corridor. Adjacent telescopic guardrails are staggered along the width of the corridor. Each of the telescopic guardrails includes a post, a hinge assembly, and a protective net. The posts are multiple posts arranged side by side, and the hinge assembly is hinged between two adjacent posts. The length of the hinge assembly is adjustable to change the distance between two adjacent posts, so as to facilitate the adjustment of the length of the entire telescopic guardrail. The protective net is provided between the multiple posts.

[0006] Furthermore, each of the columns is provided with a column base plate at its bottom end. The column base plate and the corridor are connected and fixed by expansion bolts, which facilitates the fixing of the telescopic guardrail. A reinforcing plate is provided between the column and the column base plate to improve the connection strength of the column base plate.

[0007] Furthermore, the top of the column bends inward into an arc shape, with the bend pointing towards the higher part of the corridor. This increases the reliability of personnel and material interception.

[0008] Furthermore, the hinge assembly includes a vertical plate and a horizontal plate group. Both the columns and the vertical plate are arranged vertically. The vertical plate is centrally located between two adjacent columns. Multiple horizontal plate groups are spaced apart on the vertical plate. Each horizontal plate group is hinged to the vertical plate in the middle and to two adjacent columns at both ends.

[0009] Furthermore, each of the horizontal plate groups includes two horizontal plates, which are symmetrically arranged on both sides of the vertical plate. One end of the horizontal plate is hinged to the vertical plate, and the other end is hinged to the column.

[0010] Furthermore, the hinge assembly is arranged on the outside of the column, and the protective netting is arranged on the inside of the column, with the two not interfering with each other; multiple hooks are arranged vertically at intervals on the inside of each column, and the protective netting is hooked between the hooks on the inside of multiple columns. This facilitates the installation of the protective netting on the telescopic guardrail.

[0011] Furthermore, an upper telescopic rod is inserted between the tops of multiple columns, and a lower telescopic rod is inserted between the reinforcing plates at the bottom of multiple columns. An elastic band is provided between the upper and lower telescopic rods. There are multiple elastic bands, which add a flexible buffer protection function to the telescopic guardrail. The multiple elastic bands are arranged along the axial direction of the upper telescopic rod, and there is an angle A between the elastic bands and the slope of the corridor, where A is greater than 90°.

[0012] The beneficial effects of this utility model through the above technical solution are: This utility model has a reasonable structural design. Several telescopic guardrails are set along the length of the corridor. The telescopic guardrails are placed horizontally on the corridor. There is a gap between two adjacent telescopic guardrails and they are arranged in a staggered manner. This does not affect the movement of people and materials, but also plays a role in blocking and intercepting. When people or materials roll down, they can be intercepted in time by the telescopic guardrails to prevent greater damage.

[0013] The telescopic guardrail of this invention has an adjustable length, thus adapting to corridors of varying widths. It also features elastic rings that provide flexible cushioning, forming a soft buffer barrier through multiple rings. This prevents personnel or materials from directly impacting the steel structure of the telescopic guardrail, effectively reducing potential injuries. It effectively ensures construction safety on long-distance, steep-slope conveyor belt corridors and also prevents injuries caused by objects or people falling from heights.

Detailed Implementation

[0022] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: Example 1: like Figures 1-5 As shown, a safety protection device for a long-distance, steep-slope corridor includes several retractable guardrails 1. These retractable guardrails 1 are arranged along the length of the corridor 2, and adjacent retractable guardrails 1 are staggered along the width of the corridor 2. Figure 1 and Figure 2 As shown, there is a distance L between two adjacent retractable guardrails 1, and the distance L is ≥ 5 meters, thus the interval between two adjacent retractable guardrails 1 is at least 5 meters. In this way, there is sufficient space between two adjacent retractable guardrails 1 for personnel passage and material handling, but under the influence of the retractable guardrails 1, personnel must walk in an "S" shaped route when passing through.

[0023] In this embodiment, each telescopic guardrail 1 includes a post 3, a hinge assembly 4, and a protective net 5. The posts 3 are arranged in a parallel row, and each post 3 is a 50×3 square tube structure. Two adjacent posts 3 are hinged together by two hinge assemblies 4. The length of each hinge assembly 4 is adjustable to change the spacing between adjacent posts 3, thereby changing the overall length of the telescopic guardrail 1 and adapting to corridors 2 of different widths.

[0024] The hinge assembly 4 is arranged on the outside of the column 3. The hinge assembly 4 includes a vertical plate 41 and a horizontal plate group. Both the column 3 and the vertical plate 41 are arranged vertically. The vertical plate 41 is centrally located between two adjacent columns 3, and the length of the vertical plate 41 is less than that of the column 3. Three horizontal plate groups are arranged vertically and vertically on the vertical plate 41. The middle of each horizontal plate group is hinged to the vertical plate 41, and its two ends are respectively hinged to the two adjacent columns 3.

[0025] Here, each horizontal plate group includes two horizontal plates 42, and thus a hinge assembly 4 contains six horizontal plates 42. The two horizontal plates 42 are symmetrically arranged on both sides of the vertical plate 41. One end of the horizontal plate 42 is hinged to the vertical plate 41, and the other end is hinged to the column 3. It should be noted that the hinge uses bolts and nuts, which allows for both hinged rotation and easy fixing. For example, the horizontal plate 42 is hinged to the column 3 using a bolt and nut structure, and the horizontal plate 42 is also hinged to the vertical plate 41 using a bolt and nut structure.

[0026] When the entire hinge assembly 4 is in motion: the upright plate 41 always remains parallel to the post 3, only the horizontal plate 42 will tilt. As the length of the hinge assembly 4 changes, the tilt angle of the horizontal plate 42 also changes. After tilting, the two horizontal plates 42 in each horizontal plate group are arranged in a "∧" shape. By changing the length of the hinge assembly 4, the distance between the two posts 3 is adjusted, thus allowing the entire telescopic guardrail 1 to extend and retract.

[0027] A protective net 5 is installed between the three uprights 3. Specifically, the protective net 5 is arranged on the inside of the uprights 3. During installation, multiple hooks 6 are installed at intervals on the inside of each upright 3. The hooks 6 are short columns bent into an "L" shape, and the protective net 5 is hooked between the multiple hooks 6 on the inside of the three uprights 3. The protective net 5 is a mesh structure woven from nylon rope.

[0028] The principle of this utility model is as follows: A suitable number of telescopic guardrails 1 are selected based on the length of the corridor 2, and they are installed on the corridor 2 with adjacent telescopic guardrails 1 staggered left and right. During installation, a base plate 7 is provided at the bottom of each post 3. The base plate 7 is a flat plate, and the base plate 7 is connected and fixed to the corridor 2 by expansion bolts, thereby installing the post 3 on the corridor 2, and thus keeping the entire telescopic guardrail 1 fixed to the corridor 2. A reinforcing plate 8 is provided between the post 3 and the base plate 7 to improve the connection strength between the post 3 and the base plate 7.

[0029] Personnel can walk around the retractable guardrail 1 while passing through corridor 2 or materials are being transported. In the event of a slippage accident, if personnel or materials roll down corridor 2, the retractable guardrail 1 will promptly stop them, preventing further descent and more serious injury. After the main construction of the entire project is completed and before the belt conveyor is installed in corridor 2, all retractable guardrails 1 will be removed without affecting the subsequent installation of the belt conveyor on corridor 2.

[0030] To optimize the product structure, the top of column 3 is bent inward into an arc shape, with the bending direction pointing towards the upper part of corridor 2. Thus, column 3 consists of a bent section 31 and a vertical section 32. The hinge assembly 4 is installed on the vertical section 32 of column 3, and the protective netting 5 covers the entire area of ​​column 3, meaning both the bent section 31 and the vertical section 32 have protective netting 5. The bent section 31 of column 3 can better prevent the obstruction of personnel or materials.

[0031] Example 2: This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The differences are as follows: Figures 6-7 As shown, since the entire telescopic guardrail 1 is a steel structure, cushioning can be provided to reduce damage caused by collisions between personnel or materials. Specifically, an upper telescopic rod 10 is inserted between the tops of the three posts 3. Holes are opened at the top of the posts 3, and one upper telescopic rod 10 is inserted into each of the three holes. The upper telescopic rod 10 adopts an assembly structure. The upper telescopic rod 10 includes multiple short rods, with adjacent short rods connected by threads. That is, the first end of each short rod has a convex cross-section, and the last end has a concave cross-section. The concave and convex fit between adjacent short rods, along with the threaded connection, allows for the assembly of multiple short rods. The number of short rods and the length of the upper telescopic rod 10 can be adjusted.

[0032] Meanwhile, a lower telescopic rod 9 is inserted between the reinforcing plates 8 at the bottom of the three columns 3. Specifically, the column base plate 7 needs to be lengthened, and the length of the reinforcing plate 8 also increases accordingly. In addition, holes are also made in the reinforcing plate 8, and the lower telescopic rod 9 is inserted into the holes. The structure and application of the lower telescopic rod 9 are the same as those of the upper telescopic rod 10, and will not be described in detail here.

[0033] With telescopic rods installed at the top and bottom of the column 3, an elastic band ring 11 is provided between the upper telescopic rod 10 and the lower telescopic rod 9. The elastic band ring 11 is a flat ring structure formed by winding an elastic flat strip. That is, it is based on an elastic flat strip, with Velcro at the ends. After the Velcro at the ends is fastened, the entire elastic flat strip is wound to form a flat ring similar to an "O", which can then be fixed between the upper telescopic rod 10 and the lower telescopic rod 9. The elastic band ring 11 is always in a taut state, so that the two telescopic rods are under stress.

[0034] When installing, the elastic band ring 11 can pass through the mesh of the protective net 5 to avoid the protective net 5 interfering with the installation of the elastic band ring 11. Alternatively, the protective net 5 at the bent section 31 of the column 3 can be directly removed, thus avoiding the protective net 5 interfering with the installation of the elastic band ring 11.

[0035] Multiple elastic band rings 11 are arranged along the axial direction of the upper telescopic rod 10, with an angle A greater than 90° between the elastic band rings 11 and the slope of the corridor 2. This forms a flexible protective barrier in front of the telescopic guardrail 1. If personnel or materials roll down, they will first collide with this flexible barrier, be cushioned, and then be stopped by the telescopic guardrail 1. The elastic band rings 11 thus play a buffering role.

[0036] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
