[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1:

[0025] As per the instruction manual Figures 1-4 As shown, a mobile lifting machine includes a mobile frame 1, a control box 2, and a lifting mechanism 3. The lifting mechanism 3 is a chain-type multi-stage lifting track driven by a hydraulic cylinder 4. The hydraulic cylinder 4 is a hydraulic telescopic cylinder. One end of the mobile frame 1 is connected to the bottom of the control box 2, and a U-shaped base structure is formed between the mobile frame 1 and the control box 2. Universal wheels 5 are provided at the four corners of the bottom of the mobile frame 1, eliminating the original fixed support legs, saving the floor space during use, making it suitable for more usage scenarios, and simplifying the operation process.

[0026] In this utility model, multiple counterweights 6 are provided at the bottom of the control box 2. The control box 2 is equipped with a hydraulic system 7, which includes a battery 13, an electric motor 14, and a hydraulic pump 15 driven by the electric motor 14. The hydraulic pump 15 is connected to the oil cylinder 4 and provides hydraulic power to the oil cylinder 4. This machine can be charged by its own power cord. For special requirements, the battery 13 can be removed separately for charging to meet different safety requirements.

[0027] In this utility model, the top of the control box 2 is provided with an operation panel 8 and a display screen 9. The operation panel 8 has multiple control buttons. The display screen 9 allows users to clearly know the machine's power voltage and operating status. The display screen 9 has handles 10 on both sides. The outer side of the display screen 9 is provided with a protective shell 16, and the handles 10 are located on both sides of the protective shell 16. The position of the handles 10 conforms to ergonomics and is convenient for use.

[0028] In this utility model, a guide mast 11 is fixed on one side of the control box 2 at the U-shaped base structure. The oil cylinder 4 is located inside the guide mast 11, and a dust cover 17 connected to the bottom of the control box 2 is provided at the bottom of the guide mast 11. One side of the guide mast 11 is slidably connected to the lifting mechanism 3, and the other side of the lifting mechanism 3 is slidably connected to the lifting platform 12. The width of the lifting platform 12 is greater than or equal to the width of the moving frame 1, and the lifting platform 12 is a rectangular frame structure. When the upper end of the lifting platform 12 is lifted to the top by the lifting mechanism 3, it is flush with the top of the lifting mechanism 3.

[0029] In this utility model, an alarm 18 is provided on one side of the top of the guide mast 11. The alarm 18 is an audible and visual alarm that integrates a buzzer and a red LED light. When an abnormality occurs, it will promptly alarm and remind the operator to handle the situation.

[0030] In practical implementation, when the operator presses the control button on the control panel 8, the motor 14 in the hydraulic system 7 starts working, driving the hydraulic pump 15 to run. The hydraulic pump 15 delivers hydraulic oil to the cylinder 4. The piston in the cylinder 4 moves linearly under the pressure of the hydraulic oil, thereby driving the transmission chain connected to the piston to move. The transmission chain is connected to the lifting mechanism 3, which in turn drives the lifting mechanism 3 to slide up and down along the guide mast 11, ultimately realizing the raising or lowering of the lifting platform 12. During the lifting process, the guiding function of the guide mast 11 ensures that the movement trajectory of the lifting platform 12 is vertical. The dust cover 17 prevents dust from entering the lifting mechanism 3, protecting the equipment. The alarm 18 monitors the equipment status in real time during operation and promptly alarms when an abnormality occurs, reminding the operator to handle the situation.

[0031] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
