Description

Technical Field

[0001] This utility model belongs to the field of overhead crane power collection equipment, specifically relating to a bipolar magnetic slider power collection device for overhead cranes. Background Technology

[0002] Overhead cranes, also known as bridge cranes, are lifting devices that span over workshops, warehouses, and material yards for material handling. During operation, the current collector is a crucial component, used to draw electrical energy from the crane's rails to ensure its normal operation.

[0003] Currently, traditional overhead crane current collectors typically use a slider-line contact method to conduct electricity. However, existing slider current collectors have some problems during use, such as: unstable contact pressure between the slider and the line, which can easily lead to poor contact and affect the conductivity; at the same time, the friction is large when the slider slides on the line, which can easily cause wear on the slider and the line, shortening their service life; the traditional current collector structure is relatively simple, and during overhead crane operation, especially at high speeds or when subjected to vibration, the slider is prone to displacement or jumping, leading to power outages and affecting the normal operation of the overhead crane. Utility Model Content

[0004] This invention provides a bipolar magnetic slider current collector for overhead cranes to solve the problems of poor contact, severe wear, and easy power outage of existing current collectors, which cause the overhead cranes to malfunction.

[0005] The technical solution of this utility model is: a bipolar magnetic slider current collector for an overhead crane, including magnetic sliders arranged opposite each other, a bracket is rotatably connected to the top of the magnetic slider by bolts, a connecting plate is provided at the top of the bracket, the connecting plate connects the brackets on both sides, and a conductive slide wire is provided on the magnetic slider, which is connected to the overhead crane.

[0006] As a further improvement of this utility model, the bracket is provided with multiple mounting screw holes, and the connecting plate is connected to the brackets on both sides by bolts passing through the mounting screw holes. The adjustment holes of the bracket can compensate for the height deviation and angle deviation of the track, significantly improving the installation efficiency and reducing labor costs.

[0007] As a further improvement of this utility model, the magnetic slider is provided with multiple heat dissipation holes.

[0008] As a further improvement of this utility model, the magnetic slider is made of neodymium iron boron permanent magnet material. The magnetic slider is attracted to the conductive rail by the permanent magnetic field, and the contact pressure is uniform and there is no contact pressure attenuation.

[0009] The beneficial effects of this utility model are as follows: By using opposing bipolar magnetic sliders, the current collector and conductive rail are brought into close contact through the adsorption force of permanent magnets, reducing the possibility of poor contact and improving the stability and reliability of conductivity. Furthermore, the adjustable structure of the mounting screw holes and brackets allows for quick and convenient installation of the current collector at different positions on the overhead crane, reducing installation difficulty and time costs, and occupying little space, making it suitable for various types of overhead cranes. The through-holes in the magnetic sliders effectively promote air circulation, dissipating the heat generated during operation, reducing the equipment temperature, and extending the current collector's service life. This utility model features a simple structure, stable operation, stable conductivity, convenient installation, good heat dissipation, and a compact structure, enhancing the practicality of overhead crane current collectors.

[0012] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1-2 As shown, a bipolar magnetic slider current collector for an overhead crane includes magnetic sliders 1 arranged opposite each other. The top of the magnetic slider 1 is rotatably connected to a bracket 2 by bolts. The top of the bracket 2 is provided with a connecting plate 3, which connects the two sides of the bracket 2. The magnetic slider 5 is provided with a conductive slide wire 7, which is connected to the overhead crane.

[0014] The bracket 2 is provided with multiple mounting screw holes 4, and the connecting plate 3 is connected to the bracket 2 on both sides by bolts passing through the mounting screw holes 4.

[0015] The magnetic slider 1 has multiple heat dissipation holes 6.

[0016] The magnetic slider 1 is made of neodymium iron boron permanent magnet material. The magnetic slider 1 is attracted to the conductive rail by the permanent magnetic field, and the contact pressure is uniform and there is no contact pressure attenuation.

[0017] In use, the magnetic slider 1 is magnetically attached to the conductive rail of the overhead crane. A suitable mounting plate 3 is selected based on the distance between the two magnetic sliders 1, and the brackets 2 on both sides are connected to the mounting plate 3 using bolts. When the overhead crane is running, the magnetic slider 1 moves with the crane, maintaining close contact with the conductive rail to achieve power transmission. Simultaneously, the current is transmitted to the crane's electrical equipment through the conductive wire 7 of the magnetic slider 1. During operation, the generated heat is dissipated into the air through the heat dissipation holes 6, maintaining the equipment temperature and preventing malfunction due to overheating.
