Abstract
Description
Technical Field
[0001] This application relates to the field of tunneling and anchoring machine technology, and more specifically, to a self-moving cable device for tunneling and anchoring machines. Background Technology
[0002] Roadheaders are mainly used in the mining of coal and other mineral resources, especially in situations requiring rapid tunneling and temporary support. In coal mining, roadheaders can efficiently complete the excavation and support of roadways, improving mining efficiency.
[0003] During the production process, the secondary conveyor belt transfer machine reciprocates at the tail of the tunneling and anchoring machine via a running wheel. Due to the continuous movement of the tunneling and anchoring machine, the cable management between the secondary conveyor belt and the cable platform is difficult. Cables are often squeezed and dragged on the ground, which makes them prone to damage. This increases the time for equipment failure handling and reduces tunneling efficiency. In addition, to prevent the cables from being squeezed and damaged, personnel need to follow the movement of the tunneling and anchoring machine to manually guard and drag the cables, which not only poses a safety hazard but also increases the labor intensity of personnel. Utility Model Content
[0004] The purpose of this application is to provide a cable self-moving device for a tunneling and anchoring machine, which changes the manual dragging of the cable to mechanized automatic movement following the machine, reducing the labor intensity of personnel, while increasing the protective structure to avoid wear and tear on the cable when it moves with the machine, and extending the service life of the cable.
[0005] This application provides a self-moving device for the cable of a tunneling and anchoring machine, which adopts the following technical solution:
[0006] A cable self-moving device for a tunneling and anchoring machine includes a drag trough and a flexible protective structure. The drag trough is mounted on the frame of a belt conveyor, and the flexible protective structure is located inside the drag trough and mounted on the cable. The flexible protective structure is used to protect the cable.
[0007] Preferably, the self-moving device for the tunneling and anchoring machine cable further includes a first bracket, which is mounted on the frame of the belt conveyor. A lifting ring is provided at the lower end of the first bracket, through which the cable passes.
[0008] Preferably, the flexible protective structure is assembled from multiple cable clamps in sequence.
[0009] Preferably, two adjacent cable clamps are rotatably connected.
[0010] Preferably, a protective pad is provided on the inner side of the drag groove.
[0011] Preferably, a second support is provided between the drag trough and the belt conveyor frame.
[0012] Preferably, the first bracket is fixed to the belt conveyor frame by bolts, and the second bracket is fixed to the belt conveyor frame by bolts.
[0013] Compared with the prior art, the beneficial effects of this application are as follows:
[0014] This application, by setting up a drag trough and a flexible protective structure, allows the cable to automatically move along with the conveyor belt as the secondary conveyor belt transfer machine reciprocates behind the tunneling and anchoring machine. This eliminates the need for dedicated personnel to monitor the cable, saving costs. Because the cable is placed in the drag trough, the cable will not drag on the ground during the retraction process, ensuring that the cable is not damaged during the dragging process and eliminating the risk of cable leakage. Furthermore, the flexible protective structure can protect the cable and extend its service life.
[0015] The entire device is installed on the belt conveyor frame, which is advantageous in the narrow and complex environment of underground tunnels. It is also inexpensive to manufacture and has an attractive appearance. Attached Figure Description

[0028] Example
[0029] like Figure 1-3 As shown in the embodiment of this application, the self-moving device for the cable of the tunneling and anchoring machine includes a drag trough 1 and a flexible protective structure 2. The drag trough 1 is installed on the frame 3 of the belt conveyor, and the flexible protective structure 2 is located inside the drag trough 1. The flexible protective structure 2 is installed on the cable 4 and is used to protect the cable 4.
[0030] When the secondary conveyor belt transfer machine 10 reciprocates at the tail of the conveyor belt, the cable 4 automatically moves with it, eliminating the need for dedicated personnel to monitor it and saving costs. Since the cable 4 is placed in the drag trough 1, the cable 4 will not drag on the ground during the retraction process, eliminating the risk of cable 4 leakage. During the movement of the cable 4, the flexible protective structure 2 can protect the cable 4 and extend its service life. The entire device is installed on the conveyor belt frame 3, which is beneficial for the narrow and complex environment of underground tunnels. It is also inexpensive to manufacture and has an attractive appearance.
[0031] In this embodiment, the self-moving device for the tunneling and anchoring machine cable also includes a first bracket 5, which is mounted on the belt conveyor frame 3. A lifting ring 6 is provided at the lower end of the first bracket 5, and the cable 4 passes through the lifting ring 6.
[0032] In this embodiment, the flexible protective structure 2 is assembled from multiple cable clamps 7 in sequence.
[0033] In this embodiment, the two adjacent cable clamps 7 are rotatably connected to form a drag chain-like structure, which can better pull and protect the cable 4, making the dragging smooth and with low resistance.
[0034] In this embodiment, a protective pad 8 is provided on the inner side of the drag groove 1. The protective pad 8 plays a protective role, reduces the wear of the flexible protective structure 2, and extends the service life of the flexible protective structure 2.
[0035] In this embodiment, a second bracket 9 is provided between the drag trough 1 and the belt conveyor frame 3, and the second bracket 9 is used to support the drag trough 1.
[0036] In this embodiment, the first bracket 5 is fixed to the belt conveyor frame 3 by bolts, and the second bracket 9 is fixed to the belt conveyor frame 3 by bolts. The bolt fixing method facilitates the assembly and disassembly of the first bracket 5 and the second bracket 9.
