[0017] like Figure 1 As shown in this embodiment, the utility model includes a bottom frame 1, a scissor-type lifting mechanism 2, a lifting work platform 3 and a hydraulic cylinder assembly 4. The scissor-type lifting mechanism 2 is limited and matched on the top of the bottom frame 1. The bottom frame 1 supports the lifting work platform 3 through the scissor-type lifting mechanism 2. The hydraulic cylinder assembly 4 is limited and matched within the scissor-type lifting mechanism 2. The movable end of the hydraulic cylinder assembly 4 is connected to the lifting work platform 3. The lifting work platform 3 is equipped with a hydraulic cylinder control device 5, which is connected and matched with the hydraulic cylinder assembly 4. It can be seen that the bottom frame 1 supports and limits the scissor-type lifting mechanism 2, the scissor-type lifting mechanism 2 plays a lifting role for the lifting work platform 3, the hydraulic cylinder assembly 4 provides a driving force for the scissor-type lifting mechanism 2, and promotes the conversion of the horizontal telescopic motion into vertical up and down motion, thereby achieving the purpose of lifting. The hydraulic cylinder control device 5 controls the hydraulic cylinder assembly 4, so that the hydraulic lift can operate at different heights to meet the needs of various high-altitude operations.

[0018] like Figure 3 and Figure 4As shown, in this embodiment, a hydraulic cylinder mounting seat 6 is provided on the scissor-type lifting mechanism 2, and the hydraulic cylinder mounting seat 6 is limitedly matched with the hydraulic cylinder assembly 4. The top surface of the bottom frame 1 and the two sides of the bottom surface of the lifting work platform 3 are respectively provided with an articulated seat 7 and a slide rail 8, and the scissor-type lifting mechanism 2 is respectively matched with the articulated seat 7 and the slide rail 8. It can be seen that the scissor-type lifting mechanism 2 supports and fixes the hydraulic cylinder mounting seat 6, and the hydraulic cylinder mounting seat 6 supports and limits the hydraulic cylinder assembly 4, so that the hydraulic cylinder assembly 4 can move following the posture change of the scissor-type lifting mechanism 2. The bottom frame 1 and the lifting work platform 3 respectively support and fix the articulated seat 7 and the slide rail 8. The articulated seat 7 articulates and limits one end of the scissor-type lifting mechanism 2, so that the scissor-type lifting mechanism 2 rotates and cooperates on the top surface of the bottom frame 1. The slide rail 8 slides one end of the scissor-type lifting mechanism 2, so that the scissor-type lifting mechanism 2 slides and cooperates on the top surface of the bottom frame 1, thereby making the posture change of the scissor-type lifting mechanism 2 smoother.

[0019] like Figure 2 As shown, in this embodiment, the bottom frame 1 includes a number of spiral support foot cups 10, a number of rollers 11, a support frame 12, an escalator 13 and a number of limit support columns 14, and the number of spiral support foot cups 10 and the number of rollers 11 are evenly fixed and matched at the bottom of the bottom frame 1, and the spiral support foot cups 10 and the rollers 11 are respectively limited with the ground, one end of the support frame 12 is fixedly matched with one side of the bottom frame 1, and the other end of the support frame 12 is connected and matched with the escalator 13, and the number of limit support columns 14 are fixedly matched with the top surfaces around the bottom frame 1, and the limit support columns 14 are limited with the lifting work platform 3. It can be seen that the support frame 12 supports and fixes the spiral support foot cups 10, the rollers 11, the escalator 13 and the limit support columns 14. The spiral support foot cups 10 support the overall weight of the hydraulic lift. At the same time, it also has the functions of adapting to different site environments, adjusting the height and level of the lift, dispersing the vibration generated during work, and avoiding fatigue, damage and failure of the lift components due to vibration. The rollers 11 facilitate the movement of the hydraulic lift. The escalator 13 helps the operator climb to the lifting work platform 3. The limit support columns 14 pause and limit the descending process of the scissors-type lifting mechanism 2 to prevent the scissors-type lifting mechanism 2 from continuing to descend and damaging the lift components.

[0020] like Figure 4As shown, in this embodiment, the hydraulic cylinder control device 5 includes a control handle 50 and a control box 51. The control handle 50 and the control box 51 are both fixedly fitted on the lifting work platform 3. The control box 51 cooperates with the control handle 50 and the hydraulic cylinder assembly 4, respectively. It can be seen that the lifting work platform 3 supports and fixes the control handle 50 and the control box 51. The control box 51 controls the hydraulic cylinder assembly 4, causing the scissor-type lifting mechanism to change its posture and thereby lift the lifting work platform 3. The control handle 50 controls and adjusts the control box 51, making it easier for the operator to operate the scissor-type lifting mechanism to cope with different application scenarios.

[0021] like Figure 3 As shown, in this embodiment, the scissors-type lifting mechanism 2 includes a pair of first scissors rods 20, a pair of second scissors rods 21 and a connecting rod 22, one end of the pair of first scissors rods 20 and the pair of second scissors rods 21 are respectively hingedly matched with the hinge seat 7, the centers of the pair of first scissors rods 20 and the pair of second scissors rods 21 are hingedly connected through the connecting rod 22, a pulley 23 is provided on the other end of the pair of first scissors rods 20 and the pair of second scissors rods 21, the pulley 23 is slidably matched with the slide rail 8, a number of cross beams 24 are provided between the pair of first scissors rods 20 and the pair of second scissors rods 21, and the hydraulic cylinder mounting seat 6 is provided on the connecting rod 22. It can be seen that one end of a pair of first scissor rods 20 and a pair of second scissor rods 21 are respectively hingedly matched with the hinge seat 7, and this end is a fixed end, which only plays a role of angular rotation. A pulley 23 is provided on the other end of the pair of first scissor rods 20 and the pair of second scissor rods 21, and this end is a movable end, so that the scissor-type lifting mechanism 2 can perform horizontal telescopic movement. The connecting rod 22 connects and hinges the pair of first scissor rods 20 and the pair of second scissor rods 21, so that the scissor-type lifting mechanism 2 converts the horizontal telescopic movement into vertical up and down movement. The connecting rod 22 supports and fixes the hydraulic cylinder mounting seat 6, so that when the posture of the scissor-type lifting mechanism 2 changes, it will also drive the hydraulic cylinder assembly 4 to move together, and several of the cross beams 24 play a role in enhancing the stability of the scissor-type lifting mechanism 2.

[0022] like Figure 4As shown, in this embodiment, the lifting work platform 3 includes a platform frame 30 and a lifting auxiliary ladder 31. The platform frame 30 is connected to the movable end of the hydraulic cylinder assembly 4. The lifting auxiliary ladder 31 is fixedly mounted on the side of the platform frame 30 close to the escalator 13. The lifting auxiliary ladder 31 is limited and fitted between the support frame 12 and the escalator 13. It can be seen that the platform frame 30 supports and fixes the lifting auxiliary ladder 31, and the lifting auxiliary ladder 31 provides climbing support for the operator when climbing up and down.

[0023] like Figure 4 As shown, in this embodiment, handrails are provided on both sides of the escalator 13, the platform frame 30, and the auxiliary lift ladder 31. Thus, the provision of the handrails on the platform frame 30 and the auxiliary lift ladder 31 allows the operator to grasp the handrails when climbing the escalator, preventing accidental falls or trips due to shaking or instability during the ascent and descent process. The handrails also serve as legroom limiters to prevent falls, thereby greatly improving the safety of the escalator.

[0024] like Figure 1 As shown, in this embodiment, the escalator 13 is designed to be vertical, and the auxiliary lift ladder 31 is designed to be angled. Thus, the vertical design of the escalator 13 can greatly improve space utilization, allowing the auxiliary lift ladder 31 to be embedded between the support frame 12 and the escalator 13. The angled design of the auxiliary lift ladder 31 is more ergonomic, making it more comfortable for operators to get on and off the auxiliary lift ladder 31. The angle also helps to distribute the operator's weight, reducing the burden on the knees and ankles.

[0025] In this embodiment, the working principle of the utility model is as follows:

[0026] like Figures 1 to 4 As shown, the operator moves the hydraulic lift to the desired position through several of the rollers 11, and the operator shakes several of the spiral support foot cups 10 to limit the hydraulic lift to the ground. The operator climbs to the lifting work platform 3 through the escalator 13, and the operator pulls the control handle 50 to control the hydraulic lift to rise.

[0027] When an operator encounters an emergency or requires personnel replacement, other operators can reach the lowering operation platform 3 via the escalator 13 and the lifting auxiliary ladder 31 to perform operations.

[0028] When the operator completes the work, the operator pulls the control handle 50 to control the hydraulic lift to move up and down in a cycle.

[0029] Although the embodiments of the present invention are described with practical solutions, they do not limit the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
