Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0023] The survey found that power equipment is usually large in size and weight, and traditional manual handling is inefficient, labor-intensive, and can easily delay construction time and pose safety risks.

[0024] Due to limited space, the tools used to move electrical equipment such as transformers in warehouses must have load-bearing, moving, and auxiliary functions. Considering all factors, forklifts are the only option, requiring professional forklift drivers for transport. This is especially important for emergency repairs, where both the safety of the equipment and the safety of the forklift must be ensured, which is time-consuming and labor-intensive.

[0025] Although some electrical tools are not heavy, they come in many specifications and sizes. Even though trolley transport can move them from the warehouse to the transport vehicle, manual lifting or hoisting is still required, which seriously affects the handling efficiency.

[0026] In view of the characteristics of handling space and operation, this embodiment provides an auxiliary device for the transfer of power equipment materials. Its purpose is to solve the problem of quickly moving and transporting materials and equipment in the warehouse to construction vehicles. The design requirement is that a single person can quickly move heavy materials and directly transport them to engineering vehicles, thereby improving the on-site handling efficiency and saving time for emergency repair and maintenance of power lines. It is of great significance for improving handling efficiency.

[0027] Reference Figures 1 to 3 As shown, the power equipment material transfer auxiliary device provided in this embodiment includes a mobile trolley 100 with a rear support frame, a hydraulic support rod 400 installed on the mobile trolley, a front fork 200 for loading materials, and a crank arm assembly 300 hinged to the front fork and the rear support frame. The hydraulic support rod 400 drives the crank arm assembly 300 to extend and retract, and the crank arm assembly 300 drives the front fork 200 to rise and fall.

[0028] Materials and equipment in the warehouse are usually stored in an orderly manner. For example, some heavier equipment is placed on a positioning platform, and some materials are placed on storage shelves. The cargo box of the construction vehicle also has a certain height. Usually, the placement height of materials and equipment is basically the same as the height of the construction vehicle. The front fork needs to be raised and lowered before and after handling, mainly to remove materials or equipment from the placement surface and place them on the construction vehicle. The requirements for the lifting height are not high, but sometimes it is necessary to complete the operation in a narrow space.

[0029] The front fork 200 can be structured similarly to a forklift front fork, including a U-shaped fork arm 21 and a gantry frame 22 vertically connected to the rear end of the fork arm. Before moving materials or equipment from the placement surface, the front fork is lowered to a certain height so that the fork arm 21 can be inserted under the bottom of the materials or equipment, at which point the fork arm is roughly horizontal. Then, the front fork is raised to a certain height and tilted backward at a certain angle, at which point the fork arm 21 supports the bottom of the materials or equipment, allowing the materials or equipment to be removed from the placement surface. The gantry frame 22 can limit the rear side of the materials or equipment at a certain height, facilitating movement and eliminating pulling during handling. Next, the trolley is moved to the position of the construction vehicle, the front fork extends into the truck bed of the construction vehicle, and then the front fork is lowered to a certain height so that the materials or equipment are placed inside the truck bed.

[0030] In order to make the fork rise to a certain height and tilt backward at a certain angle, in some embodiments, the crank arm assembly 300 includes a crank arm body 31, a crank arm connecting rod 32 disposed above the crank arm body, and a rear connecting rod 33 disposed behind the crank arm body. A crank arm pin 23 is provided between the left and right side walls of the portal frame 22. The front end of the crank arm body 31 extends into the portal frame and is hinged to the front end of the crank arm body. The rear end of the crank arm body 31 is hinged to both the upper end of the rear support frame and the lower end of the rear connecting rod. The front end of the crank arm connecting rod 32 extends into the portal frame and is hinged to the top beam of the portal frame. The rear end of the crank arm connecting rod 32 is hinged to the upper end of the rear connecting rod. In addition, the upper end of the hydraulic support rod 400 is hinged to the bottom of the crank arm body 31. Therefore, when the hydraulic support rod 400 pushes the front fork to rise, the crank arm body 31 rotates around the hinge fulcrum of its rear end, the upper end of the rear support frame, and the lower end of the rear connecting rod. As a result, the front end of the crank arm body 31 rises and drives the front fork 200 to rise. At the same time, the crank arm connecting rod 32 moves backward a certain distance, and the rear connecting rod 33 rotates backward at a certain angle, causing the front fork to tilt backward at a certain angle.

[0031] The aforementioned articulated boom assembly, combined with the hydraulic support rod drive, allows the fork to move vertically and horizontally, adapting to complex working environments. Its compact structure and hydraulic drive support enable operations in confined spaces, allowing for the support and lifting of various goods. This solves the problem of quickly moving most power equipment and materials from power warehouses to construction vehicles, improving the efficiency of rapid material handling and ensuring the efficiency of rapid line repair. It enhances work efficiency, is easy to operate, has a strong load-bearing capacity, and is suitable for handling materials and equipment within warehouses. Even in limited operating space, it can promptly move heavy materials and equipment, ensuring the personal safety of construction personnel, preventing injuries from manual handling, and reducing economic losses due to safety risks.

[0032] Specifically, the main body 31 of the articulated arm is a rectangular hollow tube structure to reduce weight and cost while ensuring sufficient strength. The front of the articulated arm connecting rod 32 has an isosceles trapezoidal section 321 with its upper base facing forward. The two rear ends are connected to rearwardly extending extensions 322. There are two rear connecting rods 32. The top beam of the portal frame has a downwardly extending protrusion 24 in the middle. The upper base of the isosceles trapezoidal section 321 is hinged to the protrusion. The two rear extensions 322 are hinged to the upper ends of the two rear connecting rods. The upper and lower parts of the rear connecting rod 33 both have hinge grooves 331. The rear extension 322 extends into the upper hinge groove and hinges to the rear connecting rod, while the inner converging section 1212 extends into the lower hinge groove and hinges to the rear connecting rod. The aforementioned articulated arm assembly has fewer components, allowing the use of high-strength, thickened steel materials, resulting in strong load-bearing capacity and resistance to deformation.

[0033] The rear support frame 12 includes two oblique support rods 121 extending obliquely upwards and backwards from the left and right sides of the center of the chassis of the mobile trolley, and two rear support rods 122 vertically arranged on the left and right sides of the rear end of the chassis of the mobile trolley. The upper end of the oblique support rod is simultaneously hinged to the lower end of the rear connecting rod and the rear end of the crank arm body, and the upper end of the rear support rod is connected to the oblique support rod.

[0034] The mobile trolley chassis 11 has two front extension arms 111 on the left and right sides at the front, and front rollers 112 are installed at the front ends of the two front extension arms. Two casters 125 are installed at the bottom of the rear support frame. That is, the front end of the mobile trolley chassis extends as far forward as possible, roughly corresponding to the projection of the front fork arm 21 in the middle, which is beneficial to maintaining the stability of the device when carrying equipment or materials. The rear support frame 12 also includes two vertical support rods 124 on the left and right sides at the rear of the mobile trolley chassis, a reinforcing support rod 126 connecting the two vertical support rods, and an L-shaped support rod 123 connecting the mobile trolley chassis and the vertical support rods. The casters 125 are installed at the bottom of the vertical support rods, and the upper end of the vertical support rod 124 is connected to the diagonal support rod 121.

[0035] Furthermore, since the articulated boom body 31 is located at the middle of the left and right sides above the chassis of the mobile trolley, and the two diagonal support rods 121 are located on the left and right sides of the chassis of the mobile trolley, the two rear connecting rods are correspondingly located on the left and right sides of the rear end of the articulated boom body 31. In order to enable the upper end of the diagonal support rod to be hinged to both the lower end of the rear connecting rod and the rear end of the articulated boom body, the upper part of the diagonal support rod is provided with an L-shaped structure, including an inwardly extending inner extension section 1211 and an inwardly tapering section 1212 perpendicularly connected to the inner extension section. In this way, the inwardly tapering sections 1212 of the two diagonal support rods are located close to the left and right sides of the rear end of the articulated boom body 31, corresponding to the positions of the two rear connecting rods. The components of the rear support frame are made of high-strength thickened steel, which has a strong load-bearing capacity and is not easily deformed.

[0036] Additionally, a control handle 332 is connected to the outer side of the rear linkage. Holding both control handles with both hands facilitates the movement of the mobile trolley. Using a manually pushed mobile trolley as the carrier eliminates the need for a power source, simplifying the structure and reducing costs. Furthermore, control buttons can be provided to control the hydraulic support rods. Therefore, a single person can control the movement of the trolley and the raising and lowering of the front fork, allowing for the rapid transport of heavy materials directly onto engineering vehicles.

[0037] Preferably, the hydraulic support rod is an electro-hydraulic support rod, which is vertically arranged, with its bottom end fixed to the chassis of the mobile trolley and its top end hinged to the main body of the articulated arm, providing stable and reliable support. Additionally, a power battery 13 is installed on the chassis of the mobile trolley to supply power to the electro-hydraulic support rod.

[0038] The above description is merely a specific embodiment of the invention, but the scope of protection of the invention is not limited thereto. Those skilled in the art should understand that the invention includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above.
