Description

Technical Field

[0001] The utility model relates to the technical field of crane power supply, in particular to a bridge crane power supply device. Background Art

[0002] Bridge crane is a widely used lifting equipment, mainly used for lifting materials above workshops, warehouses, material yards, etc. The working principle is to drive the lifting mechanism through an electric motor to move the hook up and down to realize the lifting and handling of goods. The crane collector is a control device installed in a crane or mobile machinery for transmitting current and signals. The collector consists of two parts: a tension device of the mechanical structure and a collector brush that directly contacts the guide rail. The tension device of the mechanical structure determines the sliding contact pressure between the collector brush and the guide rail and the stability of the mechanism. As one of the key components of the crane's electronic control system, the performance and reliability of the crane collector directly affect the overall performance and safe operation of the crane.

[0003] At present, the power supply method of bridge cranes is: a current collector is set on the bridge crane, a busbar is set on the main beam of the bridge crane, the busbar is connected to the power grid, and a brush that can slide along the busbar is set on the current collector. The current collector is usually fixed to the bridge crane by a fixed connection. When the current collector fails and needs to be repaired or replaced, it is inconvenient to repair and replace. Utility Model Content

[0004] The utility model aims to provide a power supply device for a bridge crane, so as to solve the problem that the current collector is usually fixed on the bridge crane by a fixed connection, which is inconvenient to repair and replace.

[0005] In order to achieve the above-mentioned purpose, the basic solution provided by the utility model is: a power supply device for a bridge crane, including a mounting seat, a connecting assembly and a limiting assembly, the mounting seat is detachably connected to a channel steel through the connecting assembly, a plurality of U-shaped sliders are slidably connected in the channel steel, each U-shaped slider is connected to the channel steel through a limiting assembly, and a brush is hinged on each U-shaped slider.

[0006] The principle and beneficial effect of the utility model are as follows: when in use, the mounting seat is fixed to the bottom of the crane, and the channel steel is detachably connected to the mounting seat through a connecting assembly. According to actual needs, a plurality of U-shaped sliders are installed in the channel steel through a limiting assembly, and the U-shaped sliders are moved to a suitable position. The U-shaped sliders in the channel steel are limited by the limiting assembly. When the collector fails and needs to be repaired or replaced, the channel steel is removed from the mounting seat through the limiting assembly, and the current collector in the channel steel can be taken out for repair or replacement.

[0007] Option 2 is the preferred option of the basic option. The limiting assembly includes a basket bolt. Two strip holes are respectively provided on both sides of the channel steel. The two screw rods of the basket bolt are respectively movable through the two sides of the U-shaped slider and pass through the two strip holes. The two ends of the basket bolt are respectively fixed with limiting blocks. After determining the position of the U-shaped slider in the channel steel, the limiting block is rotated so that the two screw rods of the basket bolt drive the limiting block to move into the channel steel, so that the limiting block is against the outside of the channel steel to play a limiting role.

[0008] Option three is the preferred option of the basic option. The connecting assembly includes a U-bolt. The mounting seat and the channel steel are detachably connected by the U-bolt to reduce the shaking of the channel steel in the mounting seat.

[0009] Option 4 is the preferred option of Option 3. Strip holes are provided on both sides of the mounting seat. Two gaskets are movably sleeved on the U-bolt. The U-bolt passes through the two strip holes in sequence. The two gaskets are located on both sides of the mounting seat. The channel steel in the mounting seat is moved so that the U-bolt slides in the strip hole to adjust the horizontal distance between the brush and the busbar. After the position of the channel steel is determined, the channel steel is limited by the U-bolt.

[0010] Option 5 is the preferred basic option. Several bolts are preset on the mounting base to facilitate the connection between the mounting base and the bottom of the crane. BRIEF DESCRIPTION OF THE DRAWINGS
