Description

Technical Field

[0001] The utility model relates to the technical field of cranes, in particular to a double-beam crane with a cable cleaning function. Background Art

[0002] A crane is a heavy mechanical equipment used to carry heavy objects or materials. It usually has one or more hooks or grabs that can be raised and lowered and moved, and is used to grab, lift, move and place heavy objects. Cranes can greatly improve work efficiency and reduce manual labor through their powerful lifting capacity and flexible operability, and are widely used in various industrial and commercial fields. As a type of crane, double-beam cranes have a wide range of application scenarios and efficient working performance. In the current industrial field, double-beam cranes mostly use electric reels to reel in cables to change the height of the hook, thereby achieving precise control and efficient handling of heavy objects.

[0003] When some existing double-beam cranes are in use, the cable winding devices thereon lack a cleaning mechanism, and are unable to clean the surface of the cable during the cable winding process, which can easily cause dirt, dust or other impurities attached to the surface of the cable to be rolled into the interior of the cable during the winding process, thereby increasing the risk of wear and damage to the cable and reducing the service life of the cable.

[0004] For example, the publication number CN220827171U discloses a double-beam crane with a cable tightening and stabilizing structure. The double-beam crane of this patent can prevent the cable from being entangled during winding by means of a correction roller. By changing the position of the arc-shaped support plate before and after the cable is wound, it is convenient to press the cable, reduce the looseness of the cable coil, and ensure the smooth winding work.

[0005] Although the double-beam crane of this patent has made improvements in the cable rope gathering stability, including the use of correction rollers to correct the winding direction of the cable and the adjustment of the pressure on the cable coil by movable columns and arc-shaped support plates, there is still room for improvement in the cleaning of the cable. Although the crane design improves the cable gathering stability, it does not include a cable cleaning mechanism. As a result, during the use of the cable, dirt, dust or other impurities that may be attached to the surface of the cable are easily rolled into the cable during the winding process, increasing the risk of wear and damage to the cable and shortening the service life of the cable.

[0006] Therefore, it is necessary to invent a double-beam crane with cable cleaning function to solve the above problems. Utility Model Content

[0007] The utility model aims to provide a double-beam crane with a cable cleaning function to solve the above-mentioned technical problems.

[0013] The design of the reel allows the cable to be wound up and released in an orderly manner, which improves work efficiency and is also beneficial for protecting the cable and preventing it from being damaged due to random stacking and storage.

[0014] Preferably, a No. 2 motor is installed on one side of the cable bracket, and one end of the winding shaft is transmission-connected to the No. 2 motor.

[0015] The winding shaft is driven by a motor to rotate, thus realizing the automation of cable winding.

[0016] Preferably, a rope-blocking plate is fixedly connected to the surface of the winding shaft, and the number of the rope-blocking plates is set to two, and the two rope-blocking plates are respectively arranged at two ends of the winding shaft.

[0017] The setting of the rope stopper can effectively prevent the cable from slipping or deviating from the reel during the winding process, thereby enhancing the safety and reliability of the equipment.

[0018] Preferably, a cable is wound and rolled up on the surface of the winding shaft, and a gap is provided between the two guide rollers, and the height of the gap is greater than the diameter of the cable.

[0024] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0025] 1. By arranging a cleaning mechanism on the combing component, the surface of the cable can be cleaned while the cable is being wound up, which can prevent dust and foreign matter from being wound into the cable during the winding process, thereby reducing the risk of wear and damage to the cable and extending the service life of the cable;

[0026] 2. The No. 1 motor drives the ball screw to rotate back and forth in both directions, so that the cleaning mechanism drives the cable to move back and forth left and right, thereby facilitating the cable to be evenly wound on the reel, ensuring the uniformity and tightness of the cable winding.
