Description

Technical Field

[0001] This utility model relates to the technical field of coal mine roadway excavation equipment, and in particular to a mobile cable trough device for a coal mine tunneling and anchoring integrated machine. Background Technology

[0002] In coal mine roadway excavation operations, the tunnel boring machine (TBM) needs to be powered by a long-distance cable. Existing cables and cable trays have the following defects:

[0003] Movement jamming and wear: Traditional cable trays are mostly rigid structures. When the equipment moves, the cable is prone to friction and jamming with the tray, which leads to damage to the insulation layer and shortens the average service life by more than 30%.

[0004] The weight of the cable itself and the bending resistance often cause loose joints and broken core wires. Equipment downtime caused by cable dragging accounts for 25% of the total failures.

[0005] When the tunnel floor is uneven, the cable trough cannot follow flexibly and is prone to being suspended or squeezed, which affects the continuity of tunneling.

[0006] Cable troughs are complex to disassemble and assemble, and multiple sections of the trough need to be disassembled during maintenance.

[0007] Therefore, this utility model proposes a mobile cable trough device for a coal mine tunneling and anchoring integrated machine to solve the problems existing in the prior art. Utility Model Content

[0008] To address the aforementioned problems, this utility model proposes a mobile cable trough device for a coal mine tunneling and anchoring integrated machine. When the mobile cable trough device is being dragged, the cable support frame pulls the cable trough and cable simultaneously, preventing the cable from rubbing against or getting stuck in the trough, thus reducing wear and tear and extending the continuous operation time of the equipment.

[0009] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a mobile cable trough device for a coal mine tunneling and anchoring integrated machine, including a first trough, a second trough and a cable support frame, wherein the second trough is provided with multiple sets, and adjacent sets of the second trough are hinged to each other, and one end of the second trough and the first trough are hinged to each other.

[0010] The cable support frame is used to be installed on the cable support device plate of the tunneling and anchoring machine. One end of the first groove is hinged to the lower end of the cable support frame. The interior of the first groove and the second groove is used to insert cables, and one end of the cable passes around the cable support frame and connects to the tunneling and anchoring machine.

[0011] A further improvement is that a connector arm is connected to the upper part of one end of the first trough, and a connector is provided at the bottom of the cable support frame, with the connector arm hinged to the connector.

[0012] A further improvement is that: the connector arm is provided with a first hinge hole, a hinge rod is inserted into the inside of the connector, and the connector arm is hinged to the hinge rod through the first hinge hole.

[0013] A further improvement is that: both sides of one end of the second groove are provided with connecting pieces, and the connecting pieces are provided with second hinge holes; both sides of the interior of the first groove and the second groove are provided with third hinge holes; the second hinge holes and the third hinge holes are hinged together by bolts, and the outer end of the bolts is threaded with nuts.

[0014] A further improvement is that a fixing plate is provided on one side of the cable support frame, and fastening screws are provided on the fixing plate. The fixing plate is fixed to the cable support device plate of the tunneling and anchoring machine by the fastening screws.

[0015] A further improvement is that the outer side of the cable support frame is covered with a rubber sheath, and one end of the cable passes around the rubber sheath.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a first groove and multiple sets of second grooves to form a cable groove. The first groove is hinged to the cable support frame. The cable passes through the first groove and the second groove and goes around the cable support frame. When dragging, the cable support frame pulls the cable groove and the cable synchronously. The cable will not rub or get stuck with the groove, reducing the wear rate and extending the continuous operation time of the equipment.

[0018] 2. In this utility model, the cable bypasses the outer rubber sleeve of the cable support frame before connecting to the tunneling and anchoring machine for power supply. The cable power supply joint is not subjected to stress, which avoids loosening of the joint and breakage of the core wire, thus reducing the failure rate.

[0019] 3. In this utility model, the two adjacent sets of second grooves are hinged to each other, and the second groove at one end is hinged to the first groove, which facilitates multi-segment rotation and flexibly adapts to the undulations of the tunnel floor.

[0020] 4. In this utility model, the two adjacent sets of second grooves and the second groove and the first groove are installed through the second hinge hole on the connecting piece, which is matched with the bolt and nut and the third hinge hole, which facilitates individual disassembly and improves maintenance efficiency.
