[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1 - 2 , the embodiments of the present invention include:

[0022] As Figure 1 and Figure 2 shown, the electric lifting ladder for CNC machine tool assembly includes: a base 1, a column 4, a lifting platform 2, a lifting drive device, and a ladder assembly. The lifting platform 2 is arranged above the base 1. The column 4 is vertically arranged at the bottom of the lifting platform 2 and extends downward into the base 1. A guide sleeve 5 corresponding to the column 4 is arranged in the base 1. The lifting platform 2 has a rectangular structure. In this embodiment, the columns 4 are distributed at the four corners of the bottom of the lifting platform 2. Through the cooperation of the four groups of columns 4 and the guide sleeves 5, the lifting guidance of the lifting platform 2 is carried out to ensure the stability of the lifting platform 2.

[0023] A flexible dust-proof sheath 7 sleeved on the column 4 is arranged between the top of the guide sleeve 5 and the bottom of the lifting platform 2. The flexible dust-proof sheath 7 can adopt a rubber telescopic bellows, which expands and contracts with the lifting of the lifting platform 2 to avoid dust pollution of the inner holes of the column 4 and the guide sleeve 5.

[0024] The lifting drive device is arranged in the base 1 to drive the lifting of the lifting platform 2. In this embodiment, the lifting drive device includes a motor 24, a reduction gearbox 26, a right-angle gearbox 25, and a worm gear and worm lifter 8. The reduction gearbox 26 is arranged on the base 1 and fixed by screws. The motor 24 is arranged on the base and connected to the input end of the reduction gearbox 26 to drive the reduction gearbox 26.

[0025] Two right-angle gearboxes 25 are distributed at intervals along the width direction of the lifting platform 2 on both sides of the reduction gearbox 26. A coupling 27 is provided between the output end of the reduction gearbox 26 and the input end of the right-angle gearbox 25. The worm and worm gear lifters 8 are distributed at intervals along the length direction of the lifting platform 2 on both sides of the right-angle gearbox 25. An extension rod 28 connected to the input end of the worm and worm gear lifter 8 is provided at the output end of the right-angle gearbox 25. As Figure 2 shown, the four worm and worm gear lifters 8 are driven synchronously.

[0026] A flange 6 connected to the top of the lifting platform 2 is provided at the output end on the top of the worm and worm gear lifter 8, with a stable structure. The lifting of the lifting platform 2 is driven by the synchronous action of the four worm and worm gear lifters 8, with high reliability. The self-locking during hovering is achieved by utilizing the characteristics of the four worm and worm gear lifters 8 to avoid the accidental descent problem of the lifting platform 2 and improve the use safety.

[0027] In order to limit the descent of the lifting platform 2, an elastic buffer block 13 pointing upward is vertically provided in the base 1. The elastic buffer block 13 can be made of a rubber block to perform elastic buffering and limiting during the descent process of the lifting platform 2 and avoid the problem of excessive descent. In this embodiment, a backing plate 22 is provided at the top of the elastic buffer block 13, and the elastic buffer block 13 contacts the bottom surface of the lifting platform 2 through the backing plate 22 to reduce the wear of the elastic buffer block 13.

[0028] As Figure 1 shown, a limiting rod 11 extending downward to the base 1 is provided at the top of the lifting platform 2. A limiting block 12 is provided at the bottom of the limiting rod 11. As Figure 2 shown, a retaining rod 23 is provided in the base 1 above both sides of the limiting block 12. The limiting block 12 rises and falls with the limiting rod 11 and the lifting platform 2. When the limiting block 12 contacts the retaining rod 23 during the rising process, it is limited to avoid the problem of excessive rising.

[0029] In the initial state, the lifting platform 2 has a certain height. In order to facilitate the operator to climb onto the lifting platform 2, a ladder assembly is also required. The ladder assembly is provided at one end of the lifting platform 2. The ladder assembly includes a fixed pedal 20, a movable pedal 17, a first support rod 15, and a second support rod 18. The fixed pedal 20 is horizontally provided at the end of the lifting platform 2 and is fixed by screws, so that the fixed pedal 20 is fixed at the end of the lifting platform 2 and always remains horizontal.

[0030] As Figure 1As shown, the first support rod 15 is rotatably arranged at the rear sides of both sides of the fixed pedal 20 and extends obliquely downward and outward. The second support rod 18 is rotatably arranged at the front sides of both sides of the fixed pedal 20 and extends parallel to the first support rod 15. The movable pedal 17 is arranged at intervals along the length direction of the first support rod 15 below the fixed pedal 20, and the movable pedal 17 is parallel to the fixed pedal 20, forming a parallelogram structure. The height change of the lifting platform 2 can be adapted through the angle change of the first support rod 15, and the horizontality of the movable pedal 17 can be maintained, facilitating the operator to climb onto the lifting platform 2 at any height.

[0031] In this embodiment, pin shafts corresponding to the first support rod 15 and the second support rod 18 are respectively arranged on both sides of the fixed pedal 20 and the movable pedal 17, so that the first support rod 15 and the second support rod 18 can change angles synchronously.

[0032] At the bottoms of the first support rod 15 and the second support rod 18, first universal casters 16 are arranged. The first universal casters 16 are in contact with the ground to adapt to the angle change of the first support rod 15 and the second support rod 18 and support the movement of the ladder assembly, with good flexibility. At the bottom of the base 1, second universal casters 9 are arranged to support the movement of the base 1. During the assembly process of the numerical control machine tool, it is convenient to change the working position. The first universal casters 16 and the second universal casters 9 have a built-in braking function, improving the reliability during the assembly process.

[0033] A control cabinet 10 connected to the lifting drive device is arranged in the base 1. The forward and reverse rotation of the motor 24 is controlled through the controller in the control cabinet 10 to realize the lifting adjustment of the lifting platform 2. To improve the operation convenience, a control handle 14 can be added. The control handle 14 is connected to the control cabinet 10 through wired connection communication or wireless connection communication. The control handle 14 is convenient to hold, enabling the operator to remotely control the lifting.

[0034] On the top surface of the lifting platform 2, a corundum anti-slip plate 21 is arranged to improve the anti-slip and wear-resistant effects of the lifting platform 2, which is beneficial to enhancing the safety of the operator working on the lifting platform 2. A C-shaped fence 3 is arranged on the lifting platform 2. The opening of the C-shaped fence 3 corresponds to the ladder assembly, which neither affects the operator to climb onto the lifting platform 2 through the ladder assembly nor reduces the safety of the operator on the lifting platform 2. A linear fence 19 is arranged on the second support rod 28 for the safety protection of the operator when going up and down the ladder assembly.

[0035] In summary, an electric lifting ladder for numerical control machine tool assembly pointed out by the present utility model is convenient for the operator to perform high-altitude operations, has flexible movement, is beneficial to the assembly of large numerical control machine tools, is easy to operate, improves the assembly work efficiency, and has high reliability and safer use.
