Description

Technical Field

[0001] This utility model relates to the technical field of floating pump station devices, and in particular to a rail transport trolley for a floating pump station. Background Technology

[0002] Floating pump stations are common facilities used to pump leachate from tailings dams or runoff from the dam for reuse in production. They typically consist of a floating platform, intake pumps, valves, pipelines, lifting equipment, a rocker arm gantry, and rocker arm joints. During the maintenance and replacement of equipment in floating pump stations, transporting pumps, motors, and spare parts has always been a challenging issue. Because the floating platform is far from the shore, two methods are generally used for transportation.

[0003] One method involves using a winch in conjunction with a manual hoist and a railcar for transportation. Two rails are installed on the gantry crane, and a railcar with four steel wheels is placed on each rail. The end of the railcar is connected to a winch cable on the shore. When transporting equipment or spare parts, the manual hoist on the gantry crane on the shore lifts the equipment and spare parts onto the railcar. Then, the winch is activated to slowly move the equipment and spare parts from the railcar to the end of the rails. Finally, the equipment and spare parts are unloaded using the manual hoist on the floating gantry crane. When replacing equipment or spare parts and transporting them ashore, the operation sequence is reversed. Because the gantry crane is on a slope, when using the manual hoist to lift equipment or spare parts, they must be placed on the inclined railcar, a process that poses a significant safety hazard. Meanwhile, due to the long distance, the winch's wire rope needs to be very long. Since the wire rope is a flexible material, the trailer's steel wheels are prone to uneven force and deviation during towing, which may cause the trailer to overturn during lowering or raising. Furthermore, when the water level in the reservoir rises and falls, the floating pontoon will automatically rise and fall with the water level. If the water level is very low, the inclination angle of the pier will be very large, which will further increase the difficulty of transporting equipment and spare parts.

[0004] Another method is to use a crane to lift and place the equipment and spare parts. This method is fast, but it is not suitable for remote areas with narrow roads and spaces, and the lifting cost is high.

[0005] To address this issue and achieve safe transportation of large equipment and spare parts between the shore and the floating vessel, while reducing production costs, this application provides a rail transport trolley for a floating pump station. Utility Model Content

[0035] Working principle:

[0036] During installation and use, the drive motor 4 is powered via a shore-based or floating pump station.

The cable is mounted on the sheave, allowing it to freely extend or retract as the rail transport trolley moves up and down. A flexible data cable and control handle 18 are connected to the drive motor 4. The up and down movement of the rail transport trolley is achieved by controlling the forward and reverse rotation of the drive motor 4. When equipment or spare parts need to be transported, the rail transport trolley is moved to the shore gantry position, and the screw of the scissor jack 15 is manually adjusted to keep the upper base body 14 secure. Hold the equipment or spare parts horizontally, use the lifting device on the gantry crane on the shore to lift the equipment or spare parts and place them flat on the base body 14 of the rail transport trolley. After unhooking and securing the equipment or spare parts, press the down button on the control handle 18. The drive motor 4 will rotate, driving the gear 6 on the output shaft of the worm gear reducer 5 to rotate. The rail transport trolley will begin to carry the equipment or spare parts downward. When it reaches the end of the track, press the stop button on the control handle 18. The equipment or spare parts will be lifted by the lifting device on the floating gantry crane and unloaded onto the floating ship. When the replaced equipment or spare parts are transported ashore, the reverse operation procedure is performed.

[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
