Description

Technical Field

[0001] The utility model relates to the technical field of underground operation, in particular to a self-moving device for cables and pipelines on an underground excavation working face. Background Art

[0002] During tunnel boring machine (TBM) operations, dedicated personnel were assigned to manage the cables and dust-proof water pipes on-site. This was not only time-consuming and labor-intensive, but also resulted in a tangled mess of cables and pipes, a poorly maintained production environment, and, most importantly, the presence of personnel standing behind or to the side of the TBM posed a safety hazard.

[0003] Chinese patent CN220822593U discloses a cable protection and conveying mechanism for a comprehensive tunneling machine, including a protection mechanism and a power conveying mechanism, wherein the power conveying mechanism is installed on the protection mechanism; the protection mechanism includes a mounting base plate, and protection side plates are welded on both sides of the upper part of the mounting base plate; the power conveying mechanism includes a first auxiliary roller, a second auxiliary roller and a third auxiliary roller connected between the protection side plates on both sides, and the power conveying mechanism also includes a vertical plate installed on the protection side plates on both sides, a conveying drum is installed between the vertical plates on both sides, and a servo motor is installed on one side of the vertical plate. The utility model realizes safe protection of the cable drag chain through the protection mechanism, and conveys the cable drag chain through the power conveying mechanism, thereby reducing cable damage, saving working hours, reducing the labor intensity of employees, producing better safety effects, and ensuring the normal development of the mining working face.

[0004] However, the above technical solution still has the following defects: the above solution uses three auxiliary rollers for winding and storage, which may easily cause cable pulling during use, especially when multiple cables are used at the same time. If the cable specifications are different, the same pulling force may easily cause damage to the cables. Utility Model Content

[0005] Aiming at the deficiencies of the prior art, the utility model provides a self-moving device for cables and pipelines on an underground excavation working face, thereby improving on-site civilized production conditions, reducing the labor intensity of on-site employees, and automatically eliminating hidden dangers.

[0014] Beneficial effects of the utility model:

[0015] During actual use, there is friction resistance between the slide and the fixed slide bar. The cables and pipelines are placed in appropriate positions through the support frame of each sliding unit in turn and placed on the corresponding roller assemblies, so that the cables and pipelines can be hung on the fixed slide bar like a corrugated curve for storage. The front end of the pipeline and cable passes through the guide assembly and follows the tunnel boring machine. The tail end of the cable and pipeline is fixed with wire reels and other equipment, and the line can be laid out according to the actual progress of the project. During the movement of the tunnel boring machine, the cables and pipelines are laid out along with the wires. During the laying process, the cables and pipelines on the sliding unit are advanced under the action of tension, and the roller assembly rotates along with the tension. At the same time, the friction is used to transmit the cables and pipelines forward, which can realize the self-movement of the cables and pipelines, eliminating the need for manual operation by workers and making it safer. At the same time, the sliding unit is used to store the cables and pipelines. Even if they encounter instantaneous acceleration or increased tension during the laying and pulling process, they will not be stretched violently, which can avoid damage or even breakage of the cables and pipelines, and can better protect the cables and pipelines. A plurality of roller assemblies are arranged side by side on the support frame, which can be arranged in an upper and lower position or horizontally. The main purpose is to ensure that each cable and pipeline is independently placed on a group of roller assemblies without interfering with each other. The utility model improves the civilized production conditions on site, reduces the labor intensity of on-site workers, and automatically eliminates hidden dangers. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In this embodiment, there is friction resistance between the slide 32 and the fixed slide bar 31. The cables and pipelines are selected at appropriate positions and passed through the support frame 33 of each sliding unit in turn and placed on the corresponding roller assembly 34, so that the cables and pipelines can be hung on the fixed slide bar 31 like a corrugated curve for storage and accommodation. The front ends of the pipelines and cables pass through the guide assembly 2 and follow the tunneling machine. The tail ends of the cables and pipelines are fixed using equipment such as wire reels, and the wires can be laid out according to the actual progress of the project. During the movement of the tunnel boring machine, the cables and pipelines follow the payout. During the payout process, the cables and pipelines on the sliding unit follow the tension and advance. The roller assembly 34 rotates under the action of friction, and uses friction to move the cables and pipelines forward. This can achieve self-movement of the cables and pipelines, eliminating the need for manual operation by workers and making it safer. At the same time, the sliding unit is used to store the cables and pipelines. Even if they encounter instantaneous acceleration or increased tension during the laying and pulling process, they will not be violently stretched, thus avoiding damage or even breakage of the cables and pipelines, and better protecting them. Several roller assemblies are arranged side by side on the support frame, which can be arranged in an upper and lower position or horizontally. The main purpose is to ensure that each cable and pipeline is independently placed on a group of roller assemblies 34 without interfering with each other. This self-moving device improves the civilized production conditions on site, reduces the labor intensity of on-site employees, and automatically eliminates hidden dangers.

[0024] refer to Figure 3 As shown, each roller assembly 34 includes a rotating shaft 341 fixedly mounted on the support frame 33 and a roller 342 rotatably mounted on the rotating shaft 341. The diameters of the rollers 342 at both ends are larger than the diameter of the middle section. In this embodiment, the larger diameters of the rollers 342 at both ends facilitate the stable placement of cables and pipelines on the roller surface. The rollers 342 have a roughened, frosted surface to increase frictional resistance and prevent the cables and pipelines from sliding due to excessive travel under tension.

[0025] refer to Figure 2As shown, two adjacent roller assemblies 34 are arranged on the support frame 33 in an up-down structure. In this embodiment, two adjacent roller assemblies 34 are arranged on the support frame 33 in an up-down structure to form a multi-layer stacking structure.

[0026] refer to Figure 4 As shown, two adjacent roller assemblies 34 are horizontally arranged on the support frame 33, with the rotation axes of the two roller assemblies 34 located on the same straight line. In this embodiment, two adjacent roller assemblies 34 are horizontally arranged on the support frame 33, with the rotation axes of the two roller assemblies 34 located on the same straight line. This horizontal arrangement is suitable for cables and pipes with smaller diameters.

[0027] refer to Figure 2 As shown, a limit lock 35 is provided between the fixed slide 31 and the slide 32. In this embodiment, the limit lock 35 is used to adjust the position of the sliding unit and then lock it in place, allowing the sliding unit to be adjusted according to the specifications and dimensions of cables and pipes, facilitating stable installation between the sliding units. The limit lock can be composed of a threaded hole provided in the slide 32 and a threaded rod provided between the fixed slide 31 and the slide 32 to form a tightening structure.

In this embodiment, the guide assembly 2 can be stored inside the storage box 11 when not in use, and can be slid out to be temporarily locked and connected to the tunnel boring machine 2 when in use. The fixed slide bar 31 and the sliding unit are both located in the box. When in use, the guide assembly 2 is first slid out to be connected to the tunnel boring machine 2, and then the worker hangs the cables and pipes on the sliding unit to form a corrugated curve state. In the subsequent laying process, the worker only needs to replenish the cables and pipes in time according to the needs of the project to keep the rear end in a corrugated curve shape.

[0029] refer to Figure 2 As shown, the guide assembly 2 includes a support slide 21 inserted into the opening. A plurality of auxiliary rollers 22 are mounted on the upper surface of the support slide 21, supported by brackets. A sliding rod 23 is provided at the bottom of the support slide 21.
