Description

Technical Field

[0001] This utility model relates to the field of escalator technology, and in particular to a protective device for the machine rooms on both sides of an escalator. Background Technology

[0002] As an important component of public transportation, escalators are facing increasingly stringent technical requirements in bidding. Currently, subway tenders in my country often add additional safety component requirements beyond the national standards. For example, one subway tender explicitly states: "Between parallel escalators, within the horizontal truss section at the top and bottom of the escalator, a mesh protection system must be installed to ensure the safety of maintenance personnel during maintenance of one escalator and operation of the other." To meet this requirement, bolts are typically used to fix the metal mesh to the truss through the mesh openings. However, metal mesh is a non-standard component, and suppliers often have issues controlling the size and precision of the mesh openings on large-area meshes. Pre-drilling holes in the truss may result in mismatches during installation, necessitating re-drilling, leading to low installation efficiency and difficulty in adjustment. Utility Model Content

[0003] To address the aforementioned technical problems, the purpose of this utility model is to propose a protective device for the machine rooms on both sides of an escalator, which greatly reduces the difficulty of installing the metal mesh and has a high degree of installation adjustability.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A protective device for the machine room on both sides of an escalator includes an escalator truss, a metal mesh, clamping plates, bolts, and nuts. The escalator truss includes an upper chord and a lower chord. The upper chord has at least two upper mounting holes, and the lower chord has at least two lower mounting holes. The metal mesh is located between the upper and lower mounting holes. The clamping plate includes a fixed end and an extended end connected together. The fixed end has a fixing hole. When the clamping plate is connected to the upper chord, the extended end extends downward. When the clamping plate is connected to the lower chord, the extended end extends upward. The bolts pass through the fixing hole, the upper mounting hole, or the lower mounting hole and are locked with the nuts, so that the clamping plate clamps the metal mesh between the extended end and the escalator truss.

[0006] Preferably, the upper mounting holes and the lower mounting holes are evenly spaced along the horizontal direction.

[0007] Preferably, the metal mesh includes interlaced reinforcing bars, with prismatic mesh openings formed between the reinforcing bars.

[0008] Preferably, the mesh reinforcement around the metal mesh forms a serrated edge.

[0009] Preferably, the clamping plate is a stainless steel clamping plate.

[0010] Preferably, the bolt is provided with a washer, which is located on the side of the clamp away from the escalator truss.

[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0012] This utility model relates to a protective device for the machine room on both sides of an escalator, comprising an escalator truss, a metal mesh, clamping plates, bolts, and nuts. The escalator truss includes an upper chord and a lower chord. The upper chord has at least two upper mounting holes, and the lower chord has at least two lower mounting holes. The metal mesh is located between the upper and lower mounting holes. The clamping plates include a fixed end and an extended end connected together. The fixed end has a fixing hole. When the clamping plate is connected to the upper chord, the extended end extends downward; when the clamping plate is connected to the lower chord, the extended end extends upward. Bolts pass through the fixing holes, upper mounting holes, or lower mounting holes and are locked with nuts, so that the clamping plates clamp the metal mesh between the extended end and the escalator truss. The metal mesh is easy to adjust and move, without being restricted by the positioning of pre-drilled bolt holes, greatly reducing the installation difficulty. The structure is simple, versatile, and highly operable. The installation position of the metal mesh can be flexibly adjusted, reducing the overall production and installation costs. Installation and disassembly are very convenient. Attached Figure Description

[0018] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0019] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.

[0020] Furthermore, it should be noted that the directional terms such as left, right, up, and down used in the embodiments of this utility model are only relative concepts or references to the normal use of the product, and should not be considered restrictive. The implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] As attached Figure 1 The diagram shows a protective device for the machine rooms on both sides of an escalator according to this utility model. It includes an escalator truss, a metal mesh 1, a clamping plate 2, bolts 3, and nuts 4. The escalator truss includes an upper chord 5 and a lower chord 6. At least two upper mounting holes 51 are machined on the upper chord 5, and at least two lower mounting holes 61 are machined on the lower chord 6. The metal mesh 1 is located between the upper mounting holes 51 and the lower mounting holes 61. The clamping plate 2 includes a fixed end 21 and an extension end 22 connected together. The fixed end 21 has a fixing hole. When the clamping plate 2 is connected to the upper chord 5, the extension end 22 extends downwards; when the clamping plate 2 is connected to the lower chord 6, the extension end 22 extends upwards. (See attached diagram.) Figure 2 As shown, bolts 3 pass through the fixing hole, upper mounting hole 51, or lower mounting hole 61 respectively and are locked with nuts 4, so that clamping plate 2 clamps the metal mesh 1 between the extension end 22 and the escalator truss. Clamping plate 2 is a stainless steel clamping plate, which firmly fixes the metal mesh 1 by virtue of the good ductility and hardness of stainless steel itself. Before the bolts 3 are tightened, the position of the metal mesh 1 can be easily adjusted and moved without being restricted by the positioning of pre-drilled bolt holes, which greatly reduces the installation difficulty.

[0022] The upper mounting holes 51 and the lower mounting holes 61 are evenly spaced along the horizontal direction to facilitate the fixing of the metal mesh 1 and prevent the metal mesh 1 from sliding in an inclined state, making the installation more convenient.

[0023] As attached Figure 3 As shown, the metal mesh 1 includes interlaced mesh bars 11, with prismatic mesh openings 12 formed between the mesh bars 11. The mesh bars 11 around the metal mesh 1 form serrated edges, so that when the fixing is completed, the concave part of the bottom edge of the metal mesh 1 can be locked onto the bolt 3, making it less prone to displacement and making the fixing more reliable.

[0024] A washer 7 is fitted on the bolt 3. The washer 7 is located on the side of the clamping plate 2 away from the escalator truss to prevent slippage between the bolt 3 and the clamping plate 2, making the contact more natural and the clamping more secure.

[0025] Compared with the traditional method of fixing with mesh and bolts, this utility model greatly reduces the requirements for the manufacturing precision of the metal mesh and the difficulty of pre-drilling. Fixing the metal mesh with stainless steel clamps also greatly reduces the difficulty of installation for workers. It also has great installation adjustability, reduces installation costs, has a simple structure, is easy to install and disassemble, and is reliably fixed.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
