Description

Technical Field

[0001] This utility model relates to the field of electromechanical transportation technology in coal mines, and in particular to a cable suspension structure for coal mines. Background Technology

[0002] In the coal mining and production process, the suspension and deployment of cables are crucial for ensuring the normal operation of underground equipment. However, due to the complex environment and confined space underground, traditional cable suspension structures present numerous problems in practical applications. For example, interference between cables, wear and tear, and insecure fixing not only affect the cable's lifespan but can also create safety hazards, threatening the safety of underground workers and equipment. Therefore, developing a cable suspension structure for coal mines that can effectively separate and secure cables is of great significance.

[0003] A search revealed a mining-grade, ground-mounted cable and liquid pipe transport vehicle disclosed in patent CN103754230B. This design uses a trench formed by multiple pulleys and partitions to separate and fix the cable and liquid pipe, employing a mining equipment train to pull the pulleys for laying. While this structure can achieve cable separation and fixation to a certain extent, its reliance on ground tracks and pulley systems makes installation and maintenance complex, especially in the confined environment of underground mines where track layout may be limited. Furthermore, this design primarily addresses the one-time laying of cables and liquid pipes, lacking protective measures for long-term cable suspension, making it difficult to prevent damage from prolonged friction or external impact. Patent CN105629413B discloses a method for suspending cable hooks. This method suspends the cable by installing cable hooks onto steel strands on the ground. This method is simple to operate and improves construction efficiency, but it is mainly suitable for overhead cable construction scenarios and has poor adaptability to the complex environment of underground coal mines. Furthermore, this method focuses more on the cable hanging process, without fully considering the securing and protection of the cables after hanging. Especially when multiple cables are laid simultaneously, the lack of effective separation measures may lead to tangling and friction between the cables, thus creating safety hazards.

[0004] Based on this, the present invention proposes a cable suspension structure for coal mines to solve the problems existing in the prior art. Utility Model Content

[0022] The structure of this coal mine cable suspension structure will be further described in detail below with reference to the accompanying drawings and embodiments of this utility model.

[0023] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments as described in this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0025] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0027] The following is combined with Figures 1 to 7 This invention describes the structure of a cable suspension structure for coal mines.

[0028] A cable suspension structure for coal mines is used to fix cables to the mine wall for effective suspension of cables within the mine, ensuring orderly cable arrangement and thus guaranteeing power supply and equipment safety. It includes a cable arrangement frame 1 and positioning plates 4. The cable arrangement frame 1 is a rectangular frame used to organize and arrange underground cables 6. Several cable positioning components 2 are detachably installed on the cable arrangement frame 1, working in conjunction with the cables 6 to protect the cable joints. The positioning plates 4 are L-shaped plate structures symmetrically arranged on both sides of the cable arrangement frame 1, detachably anchored to the mine sidewall by anchors 5. Guide rails 3 are installed on the opposite side of the positioning plates 4, working in conjunction with the cable arrangement frame 1, allowing the cable arrangement frame 1 to slide on the guide rails 3 for fine-tuning of its position to meet cable constraint requirements.

[0029] In one specific implementation, such as Figure 1 , Figure 2 and Figure 3 The main body of the cable routing frame 1 is made of metal and has a strong load-bearing capacity. Several mounting slots 11 are evenly distributed within the cable routing frame 1, penetrating the frame and working in conjunction with cable positioning components 2 for installation. Limiting holes 13 are provided on the inner sidewall of each end of the mounting slot 11. These holes work in conjunction with the cable positioning components 2 to position them after installation, allowing for flexible adjustment of the cable position.

[0030] Specifically, guide strips 12 are provided on both sides of the cable rack 1. The guide strips 12 cooperate with the guide grooves 31 provided on the guide rail 3, so that after installation, the cable rack 1 can slide along the length direction of the guide grooves 31 to adjust its position.

[0031] More specifically, the guide bar 12 is also provided with a through groove that works in conjunction with the positioning groove provided on the guide rail 3, so that when in use, the position of the cable arrangement frame 1 on the guide rail 3 can be fixed by using a pin to pass through the through groove and the corresponding positioning groove.

[0032] In one specific implementation, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 The cable positioning component 2 is a strip-shaped structure that penetrates the mounting groove 11. A positioning hole 21 is provided in the middle of the cable positioning component 2, which is used in conjunction with the cable 6 to facilitate the cable 6's passage and provide protection for the cable 6. Simultaneously, internal threads are provided at both ends of the positioning hole 21 to connect with the external threads of the cable positioning clamp 22. This is used to fix the cable 6 during installation using the clamping action of the cable positioning clamp 22, ensuring that the cable connection end is located in the positioning hole 21, thus preventing damage to the cable connection end and leakage during use.

[0033] Specifically, the cable positioning sleeve 22 is a tapered threaded sleeve with a notch, which is threaded to both ends of the positioning hole 21. As the cable positioning sleeve 22 is screwed in, its diameter gradually decreases to clamp the cable 6 and prevent the cable 6 from moving after it is fixed.

[0034] Specifically, symmetrical movable grooves are provided on both end sidewalls of the cable positioning component 2. One end of each movable groove penetrates the end sidewall of the cable positioning component 2, and a locking component 24 is movably installed within the movable groove via a spring 25. The locking head 23 of the locking component 24 penetrates the sidewall of the cable positioning component 2 and cooperates with the limiting hole 13 to lock the position of the cable positioning component 2 after installation. When it is necessary to remove the cable positioning component 2, simply push the locking component 24 manually to move it, causing the locking head 23 to retract from the limiting hole 13.

[0035] In one specific implementation, such as Figure 1 , Figure 5 and Figure 6The guide rail 3 is further provided with a through post 32, which cooperates with the movable groove 41 provided on the positioning plate 4. A fastening nut is provided on the through post 32 for fixing the guide rail 3 to the positioning plate 4 by rotating the fastening nut during use. The installation position of the guide rail 3 on the positioning plate 4 can be adjusted by adjusting the position of the through post 32 passing through the movable groove 41.

[0036] In one specific implementation, such as Figure 1 and Figure 7 The anchor 5 includes an anchor bolt 51 and an anchor sleeve 52. The anchor bolt 51 passes through an anchor hole on the positioning plate 4 and is threadedly connected to the anchor sleeve 52. The anchor sleeve 52 is a rigid rubber sleeve installed inside the anchor hole, and has several deformation grooves 53. This allows the anchor sleeve 52 to deform and contract during the rotation of the anchor bolt 51, thus securing it tightly within the anchor hole and fixing the suspension structure. This design enhances the fixation of the suspension structure to the mine sidewall, ensuring the overall stability of the structure.

[0037] The usage process and operating principle of the cable suspension structure for coal mines described in this utility model include: In underground coal mine operations, when multiple power supply cables need to be laid and secured, the following steps are taken: First, the positioning plate 4 is fixed to the mine sidewall using anchors 5. Then, the guide rail 3 is installed on the opposite side of the positioning plate 4 and secured with fastening nuts. Next, the cable arrangement frame 1 is installed on the guide rail 3 using guide strips 8. Specifically, the cable arrangement frame 1 is fixed to the guide rail 3 by passing the pin 11 through the through groove on the outer side of the guide strip 12 and the positioning groove on the guide rail 3. If the cable layout position needs to be adjusted, the pin can be loosened, allowing the cable arrangement frame 1 to slide along the guide rail 3. Once the position of the cable arrangement frame 1 is determined, the pin is retightened to complete the fixation. Finally, the cable positioning component 2 is inserted into the mounting groove 11 of the cable arrangement frame 1. Meanwhile, the locking element 24 is movably mounted in the movable groove of the cable positioning element 2 via a spring 25, and the locking head 23 penetrates the side wall of the cable positioning element 2 and engages with the limiting hole 13 to achieve the locking function of the cable positioning element 2. When unlocking is required, the locking element 24 is manually pushed to disengage the locking head 24 from the limiting hole 13 to complete the unlocking operation. Finally, the cable is passed through the positioning hole 21 of the cable positioning element 2 and clamped and fixed by the cable positioning clamp 22. During the tightening process of the cable positioning clamp 22, because it is a tapered threaded sleeve with a notch at one end, its diameter gradually decreases, thereby achieving a firm clamping of the cable.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
