[0055] When the utility model is implemented,

[0056] The device mainly includes a bottom support mechanism 100 , a scissor-type lifting mechanism 200 and a safety lifting platform 300 .

[0057] A bottom support mechanism 100:

[0058] The bottom support mechanism 100 is the foundation of the entire lifting device, and it includes a core frame 101, which is a rectangular shape when viewed from above. Universal wheels 102 are installed at the four corners of the lower side of the core frame 101 to facilitate the movement and positioning of the device. A handrail frame 103 is also provided on the side of the core frame 101 to provide a convenient gripping point for the operator.

The hydraulic pump 107 is connected to the middle secondary telescopic device 305 and the core hydraulic telescopic device 201 on the scissor lift mechanism 200 through the oil circuit to provide hydraulic power.

[0060] Two scissor lift mechanism 200:

[0061] The scissor lift mechanism 200 is mounted on the bottom support mechanism 100, and realizes the lifting action by the extension and contraction of the core hydraulic extension device 201. When the user controls the extension and contraction of the core hydraulic extension device 201 through the controller 104, the scissor lift mechanism 200 will rise or fall accordingly.

[0062] Three safety lifting platforms 300:

[0063] The safety lifting platform 300 is a key part of the lifting device, which includes a lower support plate 301 and an upper support platform 302. The upper support platform 302 is used to place the transformer. There is a certain distance between the lower support plate 301 and the upper support platform 302, forming an installation space 303.

[0064] Two sets of symmetrical retractable limiting mechanisms 304 are provided in the installation space 303. Each set of retractable limiting mechanisms 304 includes a middle secondary retractable device 305 and two secondary retractable rods 306 symmetrically arranged on both sides of the middle secondary retractable device 305. The retractable parts 307 of the secondary retractable rods 306 extend out of the installation space 303, and side plates 308 are symmetrically provided at the ends.

[0065] The design of the upper limit guide part on the side plate 308 is very critical, and it includes a connecting block 309, on which a limit guide frame 310 with an opening facing outward is provided. A front guide wheel 312 is provided inside the V-shaped portion 311 of the limit guide frame 310, and a rear guide wheel 314 is provided on the side wing portion 313 of the limit guide frame 310. This design enables the safe lifting platform 300 to remain stable when moving up and down, and cooperate with the guide of the reinforced concrete cement pole.

[0066] In addition, the cross-sections of the secondary telescopic rod 306 and its telescopic portion 307 are both square, which enhances the stability of the structure. They are fixedly connected to the lower support plate 301 by threaded connection, ensuring the stability of the device.

[0067] In general, the user can easily control the lifting and lowering of the scissor-type lifting mechanism 200 through the controller 104, thereby realizing automatic lifting of the transformer. At the same time, the design of the retractable limit mechanism 304 and the limit guide part on the safety lifting platform 300 ensures the stability and safety of the device during movement.

[0068] The stability of the automatic lifting device for transformer installation to achieve the safety lifting platform 300 during the lifting process mainly depends on its precise mechanical design and stable support structure. The following are several key aspects to achieve stability:

[0069] Sturdy bottom support mechanism: The bottom support mechanism 100 of the device is designed to be very sturdy to provide a stable foundation. This ensures that the lifting device itself will not shake or tilt due to the load or external force during the entire lifting process.

[0070] Stability of the scissor lift mechanism: The scissor lift mechanism 200 achieves a smooth lifting action through the precise control of its core hydraulic telescopic device 201. This mechanism is designed to keep the platform level during the lifting process, thereby ensuring the safety of the transformer.

[0071] Function of the retractable limit mechanism: The retractable limit mechanisms 304 equipped with the safety lifting platform 300 play an important role in maintaining stability. These mechanisms can provide additional support and limit during the platform lifting process to prevent the platform from accidentally deflecting or tilting. In particular, when the platform is close to its maximum lifting height, these limit mechanisms can ensure the stability of the platform.

[0072] Design of guide wheels: The front guide wheels 312 and the rear guide wheels 314 on the limit guide cooperate with the reinforced concrete cement pole guide to ensure the stability and accuracy of the lifting device when it is lifted along the pole. These guide wheels reduce the friction resistance with the pole and guide the lifting device to move along the correct path.

[0073] The structure is novel and the design is unique. The relevant staff uses the controller 104 to control the extension and retraction of the core hydraulic telescopic device 201 on the scissor-type lifting mechanism 200, thereby controlling the lifting and lowering of the scissor-type lifting mechanism 200; the relevant staff uses the controller 104 to control the extension and retraction of the middle secondary telescopic device 305 on the telescopic limit mechanism 304, which is convenient for controlling the position of the limit guide part, and is convenient for the limit guide part to cooperate with the reinforced concrete cement pole guide, thereby ensuring the stability and accuracy of the lifting device when it is lifted and lowered along the pole;

[0074] High safety: The device has multiple safety designs, stable lifting mechanism, and retractable limit mechanism to ensure stability and safety during the lifting process; in particular, the design of the limit guide part enables the device to guide and cooperate with reinforced concrete cement poles, further enhancing safety;

[0075] Easy to operate: Equipped with a controller, the operator can easily control the lifting device without excessive human intervention, reducing the difficulty of operation and labor intensity.

[0076] High efficiency: The automated lifting process greatly reduces the time required to install and repair transformers, improving work efficiency. At the same time, since the device is easy to move, it can be quickly deployed in different locations, further improving work flexibility.

[0077] Strong adaptability: The design of the device enables it to adapt to reinforced concrete cement poles of different heights and diameters, increasing the wide range and flexibility of use.

[0078] The scissor lift mechanism is a common lifting equipment, mainly composed of a scissor frame, a hydraulic system, an electrical system and a base. Its working principle is to push the opening and closing of the scissor frame through the extension and contraction of the hydraulic cylinder or rigid chain and large spiral drive system to achieve lifting movement. This mechanism has high stability and safety, so it is widely used in high-altitude operations, cargo lifting and other occasions.

[0079] The scissor lift is made up of multiple scissor arms connected by hinges to form a liftable frame structure. When the hydraulic cylinder or drive system is extended or retracted, the scissor arms will open and close accordingly, thereby driving the entire lifting platform up or down. Due to the design characteristics of the scissor lift mechanism, it can withstand large loads and the lifting process is smooth, so it is very suitable for lifting large tonnage of goods and high-altitude operations.

[0080] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
