Description

Technical Field

[0001] This invention relates to the field of crane technology, specifically to a maintenance device for a beam gantry crane. Background Technology

[0002] The full name of a suspended crane is a flexible, lightweight, modular suspended crane, which is also a type of light and small lifting equipment. Suspended cranes are divided into two types: single-girder and double-girder. Their main advantages include a lifting capacity of up to 2000 kg, easy installation, and safety. Relatively speaking, they are designed for lighter loads (not exceeding 2000 kg). They are mainly used in parts assembly, manufacturing, pallet loading, injection molding, warehousing loading and unloading, and equipment maintenance. Flexible, lightweight, modular beam suspended cranes are a perfect choice when no supporting structure is allowed in a work area to avoid affecting operation.

[0003] Currently, the traditional method for routine inspection or periodic maintenance of existing cranes is to disassemble them manually using a truck crane or by hand. This method not only increases the amount of manual labor but also raises the risk to workers, increases maintenance costs, reduces the practicality of the equipment, and causes inconvenience to workers. Therefore, we provide a maintenance device for beam gantry cranes. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a maintenance device for a beam gantry crane. This device offers advantages such as ensuring convenient crane maintenance, effectively reducing manual labor, avoiding worker hazards, saving maintenance costs, improving the device's practicality, and providing convenience for workers. It thus solves the problems raised in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives of ensuring convenient crane maintenance, effectively reducing manual labor, avoiding worker hazards, saving maintenance costs, effectively improving the practicality of the device, and bringing convenience to workers, this invention provides the following technical solution: A maintenance device for a gantry crane, comprising a base, an mounting plate at the upper end of the base, a column on the upper surface of the mounting plate, a lifting beam fixedly mounted on the upper surface of the column, a control room fixedly mounted on one side of the upper surface of the lifting beam, a lifting device fixedly mounted on one side of the control room, a winding device on one side of the lifting device, a wire rope wound around the surface of the winding device, the wire rope passing through the guide rail of the lifting beam, and a hook fixedly connected to the lower surface of the wire rope.

[0008] Preferably, hydraulic support legs are fixedly installed at the four corners of the lower surface of the base, and the lower surface of each hydraulic support leg is fixedly installed on a fixed foot.

[0009] Preferably, a rotating seat is provided at the middle position of the upper surface of the base, and a support column is fixedly installed at the middle position of the upper surface of the rotating seat, and the mounting plate is fixedly connected to the upper surface of the support column.

[0010] Preferably, a number of warning lights are fixedly installed on the other side surface of the lifting beam, and each warning light is equidistant and evenly distributed.

[0011] Preferably, the column and the lifting beam form a T-shaped structure, and the control room is not in contact with the lifting device.

[0012] Preferably, the lifting device includes a lifting motor, a gearbox, and wheels, with one end of the wire rope fixedly mounted on the wheel.

[0013] Preferably, a fixing block is provided at the lower end of one side surface of the base, an electric push rod is provided on the upper surface of the fixing block, and a shovel fork is fixedly installed on the upper surface of the electric push rod.

[0014] Preferably, the fixing block is fixedly installed on the lower end of one side surface of the base, and the electric push rod is fixedly installed at the middle position of the upper surface of the fixing block.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This type of suspended crane maintenance device, by suspending the maintenance device on the upper end of the hook, controls the lifting device in the control room to lift the wire rope, so that the wire rope rises inside the guide rail, and then the wire rope is wound up by the winding device, so that the maintenance device can be lifted for maintenance. This can fully ensure the convenience of crane maintenance, effectively reduce manual labor, and save maintenance costs.

[0018] 2. This type of suspended crane maintenance device applies pressure to the hydraulic support legs installed on the lower surface of the base, pushing the fixed feet downwards to a horizontal position, so that the fixed feet can grip the ground, thereby improving the overall stability of the device and effectively avoiding danger to workers.

[0019] 3. This type of suspended crane maintenance device, by setting a swivel to drive the mounting plate installed on the upper end of the support column, can achieve 360-degree rotation without dead angles, which is convenient for lifting the maintenance device from multiple directions. By setting a shovel fork, the maintenance device can be scooped up. By pushing the shovel fork to the horizontal position by the electric push rod, the appropriate height can be effectively adjusted, thereby reducing the labor intensity of the lifting device and bringing convenience to the staff.
