Description

Technical Field

[0001] This utility model relates to the field of tunneling machine cable movement technology, and more specifically, to a cable movement device for tunneling machines. Background Technology

[0002] Currently, coal mine roadway development is generally carried out by tunneling machines. In order for the tunneling machine to work normally, power is supplied to the tunneling machine through cables as needed. When the tunneling machine is carrying out underground coal roadway development operations, it is necessary to anchor the roof and other structures. During the development and tunneling process, the tunneling machine often needs to drag the cable back and forth. Repeated forward and backward movements can easily cause accidents such as cable crushing or breakage.

[0003] In existing technologies, a suspension device is typically used in conjunction with the moving cable of the tunneling machine. For example, patent CN212927843U discloses a tunneling machine moving cable suspension device. Specifically, the middle section of the first cable is connected to the first sliding member. When the tunneling machine is tunneling, the transfer machine moves with the tunneling machine, the second support frame moves away from the first support frame, the first cable is lengthened, and the distance between the first sliding members is increased, thereby enabling power supply to the tunneling machine. When the tunneling machine finishes tunneling and retracts, the transfer machine retracts, which in turn drives the first sliding members to move, reducing the distance between the first sliding members, and the cable retracts between the two first sliding members. After the tunneling machine finishes tunneling, it moves forward with the belt conveyor, without needing to move this device separately. However, this method mainly relies on the movement of the transfer machine to indirectly adjust the moving length of the first cable through the first sliding members, and the cable needs to be reserved for multiple lengths. This leads to multiple cable segments swinging during the movement of the transfer machine, which poses a risk of entanglement and slippage, potentially causing malfunctions.

[0004] Based on the above description, there is an urgent need for a highly stable cable moving device for tunneling machines. Utility Model Content

Detailed Implementation

[0026] The specific implementation method is described below with reference to the accompanying drawings.

[0027] Example 1

[0028] Please see Figures 1 to 6 The present invention provides the following technical solution: a cable moving device for a tunneling machine.

[0029] Specifically, such as Figure 1 and Figure 2 As shown, a cable moving device for a tunneling machine includes a wire rope 1, a first mounting frame 2, a second fixing frame 3, multiple suspension components 4, and multiple guide components 5; both ends of the wire rope 1 are connected to the first mounting frame 2 and the second fixing frame 3 respectively; multiple suspension components 4 are spaced apart between the first mounting frame 2 and the second fixing frame 3; the suspension components 4 are connected to the wire rope 1; and the guide components 5 are located at one end of the suspension components 4 near the wire rope 1.

[0030] In this embodiment, the two ends of the steel wire rope 1 are connected to the first mounting frame 2 and the second fixed frame 3 respectively, forming the main load-bearing and guiding foundation of the device; wherein, multiple suspension components 4 are spaced apart between the first mounting frame 2 and the second fixed frame 3, and the suspension components 4 are connected to the steel wire rope 1, thereby using the suspension components 4 for fixed-distance suspension and stable support of the cable; the guide component 5 is set at one end of the suspension component 4 near the steel wire rope 1, which plays a guiding role for the cable, making it easy to store the cable and flexibly adjust the fixed length of the cable to prevent it from slipping during subsequent movement.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, the suspension assembly 4 includes a carrier vessel 41 and a gantry 42; the carrier vessel 41 is suspended from the wire rope 1 via the gantry 42; the guide assembly 5 is located at one end of the carrier vessel 41 near the gantry 42.

[0032] In this embodiment, the carrier 41 is suspended on the wire rope 1 by the gantry 42 and can move along the wire rope 1; the guide component 5 is located at one end of the carrier 41 near the gantry 42 and moves with the carrier 41 to ensure stable guidance of the cable.

[0033] In this embodiment, the hanger 42 serves as the connecting core, and its shape and size strictly match the diameter of the wire rope 1. Specifically, the hanger 42 is provided with an arc-shaped groove that fits the contour of the wire rope 1. The arc of the groove is consistent with the outer curvature of the wire rope, ensuring that the wire rope can be fully embedded in the groove and avoiding local wear or slippage caused by single-point contact. At the same time, the top of the hanger 42 is rigidly connected to the carrier 41 through a shaft pin. Anti-detachment baffles are provided at both ends of the shaft pin to prevent the hanger 42 from axially shifting during movement, thus ensuring the fixation of the suspension assembly 4 and the wire rope 1 from a structural perspective.

[0034] Specifically, such as Figure 2 and Figure 3 As shown, the guide assembly 5 includes a first guide roller 51 and a second guide roller 52; the first guide roller 51 and the second guide roller 52 are disposed opposite each other at both ends of the carrier 41. The guide assembly 5 also includes a guide pipe 53; the guide pipe 53 is mounted on the carrier 41; the guide pipe 53 is disposed between the first guide roller 51 and the second guide roller 52.

[0035] In this embodiment, the first conductor wheel 51 and the second conductor wheel 52 are arranged opposite to each other at both ends of the carrier 41. The cable can bypass these two conductor wheels to guide it during movement and reduce friction between the cable and other components. Furthermore, after the cable enters from the first conductor wheel 51, it passes through the conductor tube 53 and then exits from the second conductor wheel 52. The conductor tube 53 further constrains and guides the cable.

[0036] In this embodiment, the height of the conduit 53 is lower than the height of the first conduit wheel 51, so that the cable can form a certain drop when entering the conduit 53, and avoid the cable getting stuck at the entrance of the conduit 53.

[0037] In this embodiment, the conduit 53 is inclined from high to low towards the end closer to the second conductor wheel 52; this inclined structure helps the cable pass through the conduit 53 more smoothly under its own weight, reducing movement resistance.

[0038] Specifically, such as Figure 2 and Figure 3 As shown, clamping assemblies 6 are provided at both ends of the conduit 53. The clamping assembly 6 includes a pair of clamping blocks 61 and multiple memory spring posts 62; the pair of clamping blocks 61 are disposed opposite each other inside the conduit 53; the clamping blocks 61 are connected to the inner wall of the conduit 53 through the multiple memory spring posts 62.

[0039] In this embodiment, when the cable passes through the conduit 53, the memory spring column 62 will automatically adjust the position of the clamp 61 according to the diameter of the cable, so that the clamp 61 fits tightly against the surface of the cable, achieving stable clamping of cables of different diameters. It can also ensure that when the suspension assembly 4 retracts during transport, the cable will not get tangled or detach from the guide assembly 5, ensuring stable clamping during lateral movement without affecting the extension and retraction of the cable, further enhancing the stability of lateral transmission.

[0040] Specifically, such as Figures 1 to 6 As shown, the first mounting frame 2 is provided with a first trolley 7 and a second trolley 8 interlaced in a direction perpendicular to the carrier 41; the wire rope 1 passes through the bottom of the first mounting frame 2 and is wound around the second trolley 8 and the first trolley 7 in sequence. One end of the wire rope 1 that passes through the first trolley 7 is fixed by a snap-fit ​​assembly 9.

[0041] In this embodiment, the first mounting frame 2 is the secondary transport fixed frame of the tunneling machine. When the tunneling machine moves forward, the secondary transport fixed frame moves synchronously with the tunneling machine. The first trolley 7 and the second trolley 8 connected to it pull the wire rope 1 to slide along the fixed track. Since the two ends of the wire rope 1 are fixed to the second fixed frame 3 and the clamping assembly 9 respectively, a traction path in a tensioned state is formed. The suspension assembly 4 is hung on the wire rope 1 through the hanger 41. Under the traction of the wire rope, it moves laterally with the tunneling machine to realize the synchronous transmission of the cable and ensure the continuity of power supply.

[0042] In this embodiment, the first trolley 7 and the second trolley 8 on the first mounting frame 2 are staggered. During the winding process of the wire rope 1, the direction of force is changed by the trolley, which improves the traction efficiency and load-bearing capacity. The clamping component 9 consists of a rope clamp and a fence bolt. That is, the wire rope end is rigidly fixed by the rope clamp, and with the tightening effect of the fence bolt, the wire rope is always kept in a taut state to avoid unstable transmission caused by slack.
