Description

Technical Field

[0001] The present invention relates to a handling tool for electrical equipment, and more particularly to a multi-functional electric hoisting and handling trolley. Background Art

[0002] Currently, the current situation of handling work in narrow spaces within power stations is worrying. The long-term reliance on the primitive method of manual carrying on the shoulders and by hand has increasingly prominent drawbacks. During this process, staff members need to laboriously carry various equipment and materials by manpower, with extremely high labor intensity. After each day's work, they are often exhausted and bear a heavy physical burden.

[0003] In terms of efficiency, manual handling is slow, consuming a large amount of time for each round trip. When handling large or heavy items, multiple people are required to cooperate, further reducing the overall operation efficiency. Moreover, this low-efficiency handling method directly affects the project progress, resulting in the inability to complete some urgent tasks on time and posing an obstacle to the normal operation of the power station.

[0004] In terms of quality, manual handling is limited by human physical strength and energy, and it is difficult to achieve consistent precise operation. When handling precision equipment, even a slight carelessness may cause shaking and knocking, damaging the internal components of the equipment, affecting the equipment performance, and even leading to the direct scrapping of the equipment, resulting in huge economic losses.

[0005] More seriously, the method of manual carrying on the shoulders and by hand exposes the equipment to a high risk of collision damage. The narrow space itself has limited movement range, and during the handling process, if a person is slightly careless, they will collide with surrounding walls, pipes, etc., causing irreversible damage to the equipment's shell and key components. This potential risk not only increases the equipment maintenance cost but also may lead to local power outages or other safety accidents in the power station due to equipment failures, posing a serious threat to the stable operation of the power station.

[0006] In addition, in the installation work of power station equipment, for some equipment with small volume and light weight, the current installation methods also have many drawbacks. Although these equipment are small in size and light in weight, they still need to rely on large lifting equipment to complete the installation operation.

[0007] These large lifting equipment are huge in size and astonishing in weight, and it is extremely difficult to move them within the limited space inside the power station. The internal layout of the power station is usually complex, filled with various pipes, lines, and other facilities, which makes it necessary for the lifting equipment to carefully avoid obstacles during the movement process, and each move is quite laborious.

[0008] Moreover, the preparatory work for the lifting equipment is extremely cumbersome. Before each use, the staff needs to conduct a comprehensive inspection on it, including the performance detection of mechanical components, the debugging of the electrical system, the calibration of safety devices, etc. Any problem in any link may affect the subsequent installation work. Moreover, a large amount of time is also required to position and fix the equipment to ensure its stability during operation.

[0009] Due to the overly large volume of the lifting equipment, its operation is severely restricted during in-station work. It cannot flexibly reach some relatively concealed or narrow installation positions, and often requires multiple adjustments of the equipment position or the assistance of other auxiliary equipment to complete the operation, which undoubtedly further increases the difficulty and complexity of the installation.

[0010] Combined with the above factors, the installation work originally for small-sized and light-weight equipment has extremely low efficiency. It not only consumes a large amount of human, material and time costs, but may also affect the overall construction or maintenance progress of the power station due to the delay in the installation process, having an adverse impact on the normal operation of the power station.

[0011] In summary, it is particularly important to design a power multi-functional lifting and handling trolley to solve the above problems. Summary of the Invention

[0012] The present invention designs a power multi-functional lifting and handling trolley to solve the above problems. Through the leveling mechanism provided, the auxiliary robotic arm can always be kept horizontal, so that not only the lifting height space required during normal lifting can be reduced during the startup process, but also the lifting can be made more stable, playing a role in increasing the practical performance.

[0013] To solve the above technical problems, the present invention provides a power multi-functional lifting and handling trolley, including a frame assembly, a lifting mechanism and a crawler walking mechanism. The frame assembly is composed of a lower walking bracket and a bearing frame located on the lower walking bracket. A crawler walking mechanism is installed on each side of the lower walking bracket. Its characteristics are that: the bearing frame is composed of a support platform plate and a fence guard plate assembly arranged at the rear end of the support platform plate and integrally connected with it. The support platform plate is fixed on the lower walking bracket and a cargo platform is fixed on its top. The lifting mechanism is located on the support platform plate and is rotatably connected with it. A circular through groove is opened on the cargo platform at the position relative to the lifting mechanism. A leveling mechanism is provided on the lifting mechanism.

[0014] Further: The lifting mechanism includes a support frame, a robotic arm assembly, an angle adjustment oil cylinder, and an auxiliary robotic arm. There are two support frames, which are arranged opposite to each other and located on the turntable. The turntable matches the circular through groove. The mounting end of the angle adjustment oil cylinder is movably connected between the lower ends of the two support frames. The lifting telescopic robotic arm assembly is composed of a fixed robotic arm and a telescopic robotic arm assembly. The telescopic end of the angle adjustment oil cylinder is movably connected to the bottom of the fixed robotic arm. One end of the fixed robotic arm away from the telescopic robotic arm assembly is movably connected to the upper ends of the two support frames. One end of the telescopic robotic arm assembly away from the fixed robotic arm is connected with a mounting frame. One end of the auxiliary robotic arm is movably connected to the mounting frame. The leveling mechanism is arranged between the end of the fixed robotic arm away from the telescopic robotic arm assembly and the support frame, and between the auxiliary robotic arm and the mounting frame.

[0015] Still further: The leveling mechanism includes a first adjustment oil cylinder and a second adjustment oil cylinder. The mounting end of the first adjustment oil cylinder is movably connected between the two support frames. The telescopic end of the first adjustment oil cylinder is movably connected to the bottom of the end of the fixed robotic arm away from the telescopic robotic arm assembly. The fixed end of the second adjustment oil cylinder is movably connected to the mounting frame. The telescopic end of the second adjustment oil cylinder is movably connected to the auxiliary robotic arm.

[0016] Still further: A rope reel is installed at the bottom of the fixed robotic arm. A first rope guide pulley is arranged at the bottom of the fixed robotic arm near the telescopic robotic arm assembly. The bottom of the mounting frame is connected with a second rope guide pulley. A third rope guide pulley is installed inside one end of the auxiliary robotic arm away from the mounting frame. The rope wound and unwound by the rope reel sequentially bypasses the first rope guide pulley, the second rope guide pulley, and the third rope guide pulley and is connected to the hook.

[0017] Still further: The turntable is connected to the support platen through a servo rotary drive with an encoder. The lifting mechanism deflects 60 degrees to the left and right through the drive of the servo rotary drive.

[0018] Still further: The cargo platform is a rectangular platform with a length of 3.2 meters and a width of 1.2 meters.

[0019] After adopting the above structure, the beneficial effects of the present invention are as follows:

[0020] 1. The present invention uses a curved arm structure composed of an auxiliary robotic arm and a robotic arm assembly to replace the traditional straight arm structure, so as to reduce the lifting height space required during normal lifting, enabling it to complete the lifting work in a lower space.

[0021] 2. The auxiliary robotic arm in the present invention always remains horizontal under the action of the leveling mechanism, thus improving the lifting stability.
