Abstract
Description
Technical Field
[0001] The present application relates to the technical field of traveling cable, and particularly to a traveling cable insulating device with an adjusting function. Background Art
[0002] In the heavy industry field, traveling cranes and electric hoists are indispensable lifting equipment, and the choice of power supply method is crucial; for scenarios with relatively light loads or relatively simple application environments, such as small electric hoists or single-girder cranes, the method of directly supplying power with cables is often used; in the face of traveling cranes with heavy loads and complex and changeable working environments, the method of using a cable to transmit electric energy and a current collector to pick up electricity shows its unique advantages; it can not only adapt to various complex working conditions, but also ensure the stable supply of electric energy, becoming the mainstream choice for traveling crane power supply.
[0003] However, with the increase in the usage frequency of traveling cranes and the increase in the moving range of the trolley, the problem of cable wear has gradually become prominent. After wear, the cable surface becomes uneven, resulting in a significant height difference between the worn area and the unworn area; this height difference causes trouble during the process of the current collector picking up electricity, because the current collector may not be able to effectively contact the cable in the worn area, which may lead to the serious consequence of the total power supply of the traveling crane being single-phased. This not only seriously interferes with the normal operation of the traveling crane, but also poses a potential safety hazard to on-site operations, so it needs to be improved. Summary of the Utility Model
[0004] In order to solve the problem that the worn cable cannot be effectively contacted by the current collector, the present application provides a traveling cable insulating device with an adjusting function.

The cable is arranged on the push rod. A limiting member for restricting the push rod from coming out is provided on the cable clip body.
[0007] Since the height difference of the sliding wire will cause trouble in the process of collecting power from the current collector, the current collector may not be able to effectively contact the sliding wire in the worn area, which will lead to the serious consequence of phase loss of the total power supply of the crane, which not only seriously interferes with the normal operation of the crane, but also buries the hidden danger of on-site operation safety; by adopting the above technical scheme, including angle steel, the adjustment mechanism is installed on the angle steel, the adjustment mechanism includes a sliding wire clamp body, a push rod and a strong spring, the device is fixed on the crane slide rail as a whole through the angle steel, and the crane sliding wire is connected to the current collector to provide power for the crane; when the sliding wire is unevenly worn, the strong spring pushes the push rod in the groove The sliding of the sliding wire makes the sliding wire and the collector maintain a close connection, reducing the problem of phase loss, and the sliding wire clamp body limits the distance that the push rod is pushed out through the limiter; through the settings of angle steel, adjustment mechanism, etc., it can automatically push the push rod to slide in the groove, so as to adjust the position of the sliding wire and keep it in close contact with the collector, effectively solving the problem of power phase loss caused by sliding wire wear, ensuring the stable operation of the crane, and reducing the safety hazards such as sudden shutdown or loss of control of the crane due to power phase loss, which not only protects the safety of on-site operators, but also reduces production losses caused by equipment failure.

Detailed Description of the Embodiment
[0030] The following is a further detailed description of the present application in combination with the attached Figures 1-3 drawings.
[0031] An embodiment of the present application discloses an overhead crane sliding wire insulation device with an adjustment function.

[0033] Refer to Figure 1 , an insulator body 7 is installed between the sliding wire clamp body 41 and the angle steel 1. The insulator body 7 is made of insulating material. A second fixing bolt 8 is installed between the insulator body 7 and the angle steel 1. At the same time, a third fixing bolt 9 is installed between the insulator body 7 and the sliding wire clamp body 41 to ensure that the position of the insulator body 7 between the angle steel 1 and the sliding wire clamp body 41 is accurate and error-free, the installation is stable and reliable, and the possibility of the insulator body 7 coming loose under external forces such as vibration and impact during the operation of the equipment is reduced.
[0034] Refer to Figure 1 and Figure 2 , a groove 5 is formed on the sliding wire clamp body 41. The groove 5 is formed at one end of the sliding wire clamp body 41 away from the insulator body 7. The push rod 42 is slidably connected in the groove 5 of the sliding wire clamp body 41. In this embodiment, the sliding wire 2 is installed on the push rod 42, and a sliding groove 51 is formed in the groove 5 of the sliding wire clamp body 41.
[0035] Refer to Figure 1 and Figure 3 , a slider 52 is integrally formed on the push rod 42. The slider 52 is in a convex shape. The slider 52 is slidably connected in the sliding groove 51, and the number of the sliders 52 is two groups. The two groups of sliders 52 are arranged oppositely on both sides of the push rod 42. The number of the sliding grooves 51 in the groove 5 is two. The two sliding grooves 51 correspond to the two sliders 52 respectively. The slider 52 is slidably connected in the sliding groove 51, ensuring that the push rod 42 moves more smoothly in the groove 5, reducing the shaking and deviation of the push rod 42 during the movement, and ensuring the stability of the connection between the sliding wire 2 and the current collector 3.
[0036] Refer to Figure 1 , the strong spring 43 is installed in the groove 5. One end of the strong spring 43 is adhesively fixed to the bottom wall of the groove 5, and the other end of the strong spring 43 is adhesively fixed to the push rod 42.

[0038] The implementation principle of the traveling crane sliding wire insulating device with an adjusting function in the embodiment of the present application is as follows: when the sliding wire 2 is worn and uneven, the strong spring 43 pushes the push rod 42 to slide in the groove 5, and the slider 52 slides in the chute 51, so that the sliding wire 2 and the current collector 3 continue to maintain a tight connection, reducing the problem of phase loss. And the sliding wire clamp body 41 restricts the pushing distance of the push rod 42 through the limiting member 6; through the settings of the angle steel 1, the adjusting mechanism 4, etc., it can automatically push the push rod 42 to slide in the groove 5, thereby adjusting the position of the sliding wire 2 to keep it in close contact with the current collector 3, effectively solving the problem of power supply phase loss caused by the wear of the sliding wire 2, ensuring the stable operation of the traveling crane, and at the same time reducing safety hazards such as sudden shutdown or out-of-control of the traveling crane caused by power supply phase loss. It not only protects the safety of on-site operators, but also reduces production losses caused by equipment failures.
