Description

Technical Field

[0001] This utility model relates to the field of hoisting equipment, specifically to a cable reel for an electromagnetic crane. Background Technology

[0002] An electromagnetic crane (also known as an electromagnetic hoist) is an industrial device that uses electromagnetic principles to lift and transport materials. It uses an electromagnetic chuck to generate magnetic force, attracting magnetically conductive metal materials (such as steel plates and scrap steel). When the power is off, the magnetism disappears, releasing the material. Its core components include an electromagnet, a control system, and a power supply system. It features high adsorption efficiency and flexible operation. The electromagnet is located at the hook and requires a cable power supply. To accommodate hooks of different heights, the cable needs sufficient length redundancy, necessitating the use of a cable reel for cable winding. Cable reels are widely used cable storage devices in industrial production, but traditional designs have many limitations. Most cable reels on the market today use a fixed structure, typically including the reel body, slip rings, and coil springs. This structure is complex, has a high failure rate, a short product lifespan, and is prone to damage.

[0003] The improvement method is to replace the cable reel with a guide hole type cable collector, placing the cable and the collection bucket on the same vertical line, and making a guide hole above the collection bucket to ensure that the cable can be properly collected into the bucket. This device causes less wear on the cable and collects it naturally by gravity, but it also has drawbacks, such as the cable being unstable during horizontal movement. Therefore, it is necessary to design an electromagnetic crane cable reel that can solve the problem of cable instability during horizontal movement. Summary of the Invention

[0004] The purpose of this utility model is to provide a cable reel for electromagnetic cranes, which has the function of limiting the PU type spring cable during the horizontal movement of the electromagnetic crane, thereby improving the stability of the PU type spring cable.

[0005] The technical solution adopted is as follows:

[0006] A cable reel for an electromagnetic crane is installed on the electromagnetic crane. It includes a winding drum with an open top. A telescopic rod is vertically installed inside the winding drum. The upper end of the telescopic rod is connected to a mounting block. Multiple upper guide plates are hinged to the side of the mounting block. Multiple lower guide plates are hinged to the bottom end of the winding drum at the lower end of the telescopic rod. The upper and lower guide plates are hinged one-to-one. A cable inlet hole is provided on the lower end face of the winding drum. A PU-type spring cable is installed inside the winding drum and sleeved on the outside of the lower and upper guide plates.

[0007] Preferably, the mounting block is a cone shape, smaller at the top and larger at the bottom.

[0008] Preferably, the telescopic rod is an electric telescopic rod.

[0009] Preferably, the upper end of the winding drum is provided with a rubber anti-scratch layer.

[0010] Compared to existing technologies, the advantages are:

[0011] In this invention, during the raising or lowering of the electromagnetic crane, the telescopic rod control mounting block is raised to increase the angle between the upper and lower guide plates, thus preventing interference with the vertical movement of the PU-type spring cable. During the horizontal movement of the electromagnetic crane, the telescopic rod control mounting block is lowered to decrease the angle between the upper and lower guide plates. The lower guide plate is used to limit the movement of the PU-type spring cable, preventing instability of the PU-type spring cable during the horizontal movement of the electromagnetic crane.

[0015] The present invention will be further described below with reference to specific embodiments, such as... Figures 1 to 2 As shown:

[0016] Example 1: A cable reel for an electromagnetic crane, installed on an electromagnetic crane, includes a winding drum 1 with an open top. A telescopic rod 2 is vertically arranged inside the winding drum 1. The upper end of the telescopic rod 2 is connected to a mounting block 3. Multiple upper guide plates 4 are hinged to the side of the mounting block 3. Multiple lower guide plates 5 are hinged to the bottom end of the winding drum 1 at the lower end of the telescopic rod 2. The number of upper guide plates 4 and lower guide plates 5 are the same and they correspond one-to-one. The upper guide plates 4 and lower guide plates 5 are hinged one-to-one. The telescopic rod 2 extends and retracts, thereby changing the angle between the upper guide plates 4 and lower guide plates 5.

[0017] The lower end face of the winding drum 1 is provided with a wire inlet hole 6. Inside the winding drum 1, a PU-type spring cable 7 is sleeved on the outside of the lower guide plate 5 and the upper guide plate 4. During the raising or lowering of the electromagnetic crane, the telescopic rod 2 controls the mounting block 3 to raise, thereby increasing the angle between the upper guide plate 4 and the lower guide plate 5 to avoid interference with the vertical movement of the PU-type spring cable 7. During the horizontal movement of the electromagnetic crane, the telescopic rod 2 controls the mounting block 3 to lower, thereby decreasing the angle between the upper guide plate 4 and the lower guide plate 5, and using the lower guide plate 5 to limit the movement of the PU-type spring cable 7.

[0018] Example 2: A cable reel for an electromagnetic crane, installed on the electromagnetic crane, includes a winding drum 1 with an open top. A telescopic rod 2 is vertically installed inside the winding drum 1. The telescopic rod 2 is an electric telescopic rod 2, powered by a cable. An mounting block 3 is connected to the upper end of the telescopic rod 2. The mounting block 3 is a cone shape with a smaller top and a larger bottom. The cone shape of the mounting block 3 facilitates the guidance of the cable.

[0019] Multiple upper guide plates 4 are hinged to the side of the mounting block 3, and multiple lower guide plates 5 are hinged to the bottom of the winding drum 1 at the lower end of the telescopic rod 2. The number of upper guide plates 4 and lower guide plates 5 are the same and they correspond one-to-one. The upper guide plates 4 and lower guide plates 5 are hinged one-to-one. The telescopic rod 2 extends and retracts, thereby changing the angle between the upper guide plates 4 and lower guide plates 5.

[0020] The lower end face of the winding drum 1 is provided with a wire inlet hole 6. A PU type spring cable 7 is provided inside the winding drum 1 and sleeved on the outside of the lower guide plate 5 and the upper guide plate 4. A rubber anti-scratch layer 8 is provided at the upper end of the winding drum 1 to reduce the wear of the PU type spring cable 7.

[0021] The working principle is as follows:

[0022] During the raising or lowering of the electromagnetic crane, the telescopic rod 2 controls the mounting block 3 to raise, increasing the angle between the upper guide plate 4 and the lower guide plate 5, thus avoiding interference with the vertical movement of the PU-type spring cable 7. During the horizontal movement of the electromagnetic crane, the telescopic rod 2 controls the mounting block 3 to lower, decreasing the angle between the upper guide plate 4 and the lower guide plate 5. The lower guide plate 5 is used to limit the PU-type spring cable 7, ensuring its stability during the horizontal movement of the electromagnetic crane.

[0023] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
