Description

Technical Field

[0001] This utility model relates to the technical field of wire rope winch transmission components, and in particular to an electromagnetic clutch winch with wire protection function. Background Technology

[0002] Currently, wire rope winches are used in conjunction with electromagnetic clutches. By switching the energized and de-energized states of the electromagnetic clutch, the winch can be connected or disconnected from the power system. This allows for rapid control of the winch's start and brake, enabling remote operation and facilitating automated control. However, electromagnetic clutches require electrical connection to an external power source via power lines during operation. Existing electromagnetic clutches typically have their power lines directly extended from the outer wall of the clutch. During rotation, the wire rope wound around the surface of the winch is prone to slipping out of the grooves. When this slipped rope moves towards the electromagnetic clutch, it can violently contact the power line, causing wear and damage. In severe cases, it can even break the power line, affecting the clutch's lifespan and potentially leading to accidents. Therefore, a winch with a dual-function electromagnetic clutch is needed. Utility Model Content

[0003] The purpose of this invention is to provide an electromagnetic clutch winch with a line protection function, thereby solving the technical problems mentioned in the background section.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model discloses an electromagnetic clutch winch with a wire protection function, comprising a frame, two bearing seats symmetrically fixed at both ends of the frame, and a power shaft rotatably mounted between the two bearing seats. One end of the power shaft extends to the outside of the corresponding bearing seat for transmission connection with a drive device. Two electromagnetic clutches are mounted on the power shaft. The input end of each electromagnetic clutch is connected to the power shaft, and the output end is connected to a wire rope winch sleeved outside the power shaft. A connecting plate is fixedly mounted on the side of each electromagnetic clutch away from its corresponding wire rope winch. One end of the connecting plate is fixedly connected to the electromagnetic clutch, and the other end is fixedly connected to a wire protection frame disposed outside the electromagnetic clutch. The power lines of each electromagnetic clutch are led out from the inside of its corresponding wire protection frame.

[0006] Furthermore, the cable guard includes a cable guard frame. The cable guard frame has an arc-shaped mating part that matches the outer peripheral wall contour of the electromagnetic clutch on one side near the electromagnetic clutch, and a power cable through hole for the power cable to pass through is provided at the corner position. A connecting ear is fixedly provided on the other side of the cable guard frame near the connecting plate. Both the connecting plate and the connecting ear have connecting through holes and are fixedly connected by bolts passing through the connecting through holes.

[0007] Furthermore, the frame is fixedly provided with a first mounting bracket near each of the connecting plates. The first mounting bracket has an L-shaped cross-section, with its horizontal part fixedly connected to the frame and its vertical part flat against the outside of the connecting plate. The vertical part of the first mounting bracket is fixedly connected to the connecting plate and the connecting lug by bolts. The bolts are respectively provided with locking nuts that are threadedly connected to the connecting lugs and the vertical part of the first mounting bracket.

[0008] Furthermore, a second mounting bracket is fixedly provided at each end of the frame, and a tension spring is provided between the second mounting bracket and the free end of the corresponding bolt.

[0009] Furthermore, the main body material of the oil rope winch is nylon.

[0010] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0011] This invention provides a cable guard on the outer periphery of the electromagnetic clutch. The power cable of the electromagnetic clutch is led out from the inside of the cable guard. When the wire rope of the oil wire rope winch leaves the groove and moves toward the electromagnetic clutch, the oil wire rope will only contact the cable guard and not the power cable. Thus, the cable guard protects the power cable, preventing the oil wire rope from causing wear, damage, or breakage, and ensuring the service life of the electromagnetic clutch.

[0018] like Figures 1-3 As shown, an electromagnetic clutch winch with a wire protection function includes a frame 1. Two bearing seats 2 are symmetrically fixedly mounted at both ends of the frame 1. A power shaft 3 is rotatably mounted between the two bearing seats 2. One end of the power shaft 3 extends to the outside of the corresponding bearing seat 2 for transmission connection with a drive device. Two electromagnetic clutches 5 are mounted on the power shaft 3. The input end of each electromagnetic clutch 5 is connected to the power shaft 3, and the output ends are respectively connected to a wire rope winch 6 sleeved outside the power shaft 3.

[0019] Each electromagnetic clutch 5 has a connecting plate 7 fixedly installed on the side away from its corresponding wire rope winch 6. One end of the connecting plate 7 is fixedly connected to the electromagnetic clutch 5, and the other end is fixedly connected to the wire guard 8 located outside the electromagnetic clutch 5. The power lines 9 of each electromagnetic clutch 5 are led out from the inside of its corresponding wire guard 8.

[0020] The cable guard 8 includes a cable guard frame 8-1. On the side of the cable guard frame 8-1 near the electromagnetic clutch 5, an arc-shaped mating part 8-2 is provided, which matches the outer peripheral wall contour of the electromagnetic clutch 5. A power cable through hole 8-3 is provided at the corner for the power cable 9 to pass through. On the other side of the cable guard frame 8-1, near the end of the connecting plate 7, a connecting lug 8-4 is fixedly provided. Both the connecting plate 7 and the connecting lug 8-4 have connecting through holes and are fixedly connected by bolts 10 passing through the connecting through holes 8-4.

[0021] This invention provides a cable guard on the outer periphery of the electromagnetic clutch. The power cable of the electromagnetic clutch is led out from the inside of the cable guard. When the wire rope of the oil wire rope winch leaves the groove and moves toward the electromagnetic clutch, the oil wire rope will only contact the cable guard and not the power cable. Thus, the cable guard protects the power cable, preventing the oil wire rope from causing wear, damage, or breakage, and ensuring the service life of the electromagnetic clutch.

[0022] The frame 1 has a first mounting bracket 11 fixedly installed near each of the connecting plates 7. The first mounting bracket 11 has an L-shaped cross section. Its horizontal part is fixedly connected to the frame 1, and its vertical part is flat against the outside of the connecting plate 7. The vertical part of the first mounting bracket 11 is fixedly connected to the connecting plate 7 and the connecting lug 8-4 by bolts 10. The bolts 10 have locking nuts 12 threadedly connected to them at the positions located on the outside of the connecting lug 8-4 and the vertical part of the first mounting bracket 11.

[0023] In addition, a second mounting bracket 13 is fixedly installed at both ends of the frame 1 by welding. A tension spring 14 is provided between the second mounting bracket 13 and the free end of the corresponding bolt 10. By locking the bolt with two locking nuts and cooperating with the tension function of the tension spring, the tightening ability of the bolt can be improved, thereby ensuring the installation firmness of the cable guard.

[0024] As a further improvement to this utility model, the main body of the wire rope winch 6 is made of nylon, which ensures sturdiness and durability while effectively reducing the overall weight of the wire rope winch, thereby reducing the power consumption required to drive the wire rope winch to rotate.

[0025] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
