[0032] The control panel 6 is located above the bottom shell 1, and the scissor lift 3 is located between the bottom shell 1 and the control platform;

[0033] A small car 2 is fixedly installed on the bottom of the bottom shell 1. The small car 2 is an AVG car. The AVG car is existing technology, and its specific structure and working principle will not be described in detail here.

[0034] The two connecting rods at the top of the scissor link 3 are rotatably fitted with the first slider 18, and the bottom of the operating table 6 is provided with an alignment mechanism to assist the two first sliders 18 in centering movement.

[0035] The bottom two connecting rods of the scissor link 3 are rotatably fitted with second sliders 23. The bottom shell 1 is provided with a double threaded rod 25. The outer sides of both ends of the double threaded rod 25 are rotatably fitted with second bearing seats 29 that are fixed to the bottom shell 1. Both ends of the double threaded rod 25 are fitted with matching nut sleeves 24. The two nut sleeves 24 are respectively fixed to the two second sliders 23.

[0036] The bottom shell 1 is equipped with a drive assembly that rotates the double threaded rod 25;

[0037] A pair of fourth bearing seats 36 are fixed at each of the four corners inside the bottom shell 1, and each pair of fourth bearing seats 36 is rotatably mounted with a shaft grooved wheel 37. A rotating mechanism is provided between the wheel axle of the shaft grooved wheel 37 and the double threaded rod 25 to make the two rotate synchronously.

[0038] The groove of the axle-grooved wheel 37 is provided with a balance rope, which can be selected as a steel rope 4. One end of the steel rope 4 is fixed to the axle-grooved wheel, and the other end of the steel rope 4 is fixed to the middle position of the top of the bottom shell 1. The bottom of the operating table 6 is fixed with a pair of support frames 9 at each of the four corners. Each pair of support frames 9 is rotatably installed with a first guide wheel 5. Each steel rope 4 is sleeved on the first guide wheel 5 adjacent to the steel rope 4.

[0039] As can be known from the above description, when the double-threaded rod 25 rotates, the two nut sleeves 24 at the two ends of the double-threaded rod 25 move synchronously and in opposite directions along the double-threaded rod 25 through the threaded transmission form. When the two nut sleeves 24 move relatively close to each other, the two nut sleeves 24 drive the first sliding blocks 18 to move relatively close to each other, respectively. The two first sliding blocks 18 cause the two connecting rods at the bottom of the scissors linkage 3 to move close to each other, and the scissors linkage 3 is elongated to lift the operating table 6. Since the wheel shaft of the axle-grooved wheel 37 and the double-threaded rod 25 are provided with a rotating mechanism for synchronous rotation therebetween, the axle-grooved wheel 37 is unwound.

[0040] Specifically, as shown in the accompanying drawings, Figure 5 The centering mechanism includes intermediate plates 15 and two connecting rods 16. The intermediate plates 15 are rotatably installed at the middle positions of the bottom of the operating table 6. One end of each of the two connecting rods 16 is rotatably installed at the two ends of each of the intermediate plates 15. The other end of each of the two connecting rods 16 is rotatably installed at the middle position of the top of each of the first sliding blocks 18. The two connecting rods 16 are centrally symmetric. When the scissors linkage 3 is elongated, the two connecting rods at the top of the scissors linkage 3 move close to each other, and the first sliding blocks 18 on the two connecting rods move close to each other. The first sliding blocks 18 rotate the intermediate plates 15 through the connecting rods 16, so that the two first sliding blocks 18 can stably complete the centering movement, and the two first sliding blocks 18 can be stably positioned in the middle region of the operating table 6.

[0041] Specifically, as shown in the accompanying drawings, Figure 5 The bottom of the operating table 6 is fixed with first fixed plates 17 at both ends. The opposite sides of the two first fixed plates 17 are commonly fixed with a plurality of first guide rods 19. The two first sliding blocks 18 are slidably sleeved on each of the first guide rods 19. The first guide rods 19 are provided to enable the first sliding blocks 18 to only move linearly relative to the operating table 6.

[0042] Specifically, as shown in the accompanying drawings, Figure 6 The top of the bottom shell 1 is fixed with second fixed plates 30 at both ends. The opposite sides of the two second fixed plates 30 are commonly fixed with a plurality of second guide rods 22. The two second sliding blocks 23 are slidably sleeved on each of the second guide rods 22. The second guide rods 22 are provided to enable the second sliding blocks 23 to only move linearly relative to the bottom shell 1.

[0043] Specifically, in conjunction with the appendix Figure 6 Appendix Figure 7 and attached Figure 8 As shown, the drive assembly includes a servo motor 21, a worm gear 26, and a worm wheel 27. Both ends of the worm gear 26 are rotatably fitted with first bearing seats 28 that are fixed to the bottom shell 1. The worm wheel 27 is coaxially fixed to the double threaded rod 25 and meshes with the worm gear 26. The servo motor 21 is fixed to the bottom shell 1, and the output shaft of the servo motor 21 is coaxially fixed to the worm gear 26. The servo motor 21 rotates the worm gear 26 through its output shaft, and the worm gear 26 rotates the double threaded rod 25 through the worm wheel 27 that meshes with it.

[0044] Specifically, in conjunction with the appendix Figure 6 and attached Figure 8 As shown, the rotating mechanism includes a transmission rod 31. Both ends of the transmission rod 31 are rotatably fitted with third bearing seats 32 fixed to the bottom shell 1. A transmission structure is provided between the transmission rod 31 and the double-threaded rod 25 to enable synchronous rotation. Both ends of the transmission rod 31 are respectively fixed to two adjacent shafted grooved wheels 37 with a universal joint 35. The transmission structure includes a main bevel gear 33 and a secondary bevel gear 34. The main bevel gear 33 is coaxially fixed to the double-threaded rod 25, and the secondary bevel gear 34 is coaxially fixed to the transmission rod 31, with the main bevel gear 33 and secondary bevel gear 34 meshing. When the double-threaded rod 25 rotates, the main bevel gear 33, coaxially fixed to the double-threaded rod 25, rotates synchronously. The main bevel gear 33 drives the transmission rod 31 to rotate through the meshing secondary bevel gear 34, and the transmission rod 31 drives the shafted grooved wheels 37 to rotate through the universal joint 35.

[0045] Specifically, in conjunction with the appendix Figure 3 and attached Figure 4 As shown, the middle part of the middle rod 10 of the scissor lift 3 is flat. The middle rod 10 of the scissor lift 3 has four through holes, through which four steel ropes 4 pass respectively. The top middle rod 10 of the scissor lift 3 has four recesses 11 fixed. A second guide wheel 12 is rotatably installed in the recesses 11. The four steel ropes 4 are respectively sleeved on the four second guide wheels 12. The second guide wheels 12 are used to guide the direction of the steel ropes 4. Even if the steel ropes 4 pass through the through holes vertically, the scissor lift 3 tends to be straight because the steel ropes 4 are in a taut state, thereby further improving the bending resistance of the scissor lift 3.

[0046] Specifically, in conjunction with the appendix Figure 3 and attached Figure 5As shown, the two ends of the top two links of the scissors linkage 3 are fixed with the support rods 14 coaxially arranged therewith, the bottom two sides of the operating table 6 are fixed with the side support plates 13, the two ends of the two side support plates 13 are provided with the guide grooves 20, and one end of the four support rods 14 is respectively slidably arranged in the four guide grooves 20. The support rods 14 are matched with the guide grooves 20, thereby improving the stability of the first sliding block 18 during movement. Meanwhile, the support rods 14 provide upward supporting force through the side support plates 13.

[0047] Specifically, combined with the accompanying drawings, Figure 1 - the accompanying drawings Figure 3 As shown, the operating table 6 is fixed with the guardrails 7, which are arranged to provide support points for workers. One side of the guardrails 7 is not closed, and the horizontal bars of the guardrails 7 are fixed with the control consoles 8. The control consoles 8 are fixed with the control panels, and the interiors of the control consoles 8 are fixedly installed with the controllers. The controllers are prior art, and their specific structures and working principles are not described in detail here. It is supplemented that the controllers are electrically connected with the above-mentioned various electrical devices.

[0048] It is supplemented that after the entire operating platform is installed, the steel ropes 4 are pre-tightened, so that the steel ropes 4 are kept in a tense state.

[0049] Working principle: the worker stands on the operating table 6, and then operates the control console 8. The entire operating platform is moved by the trolley 2. After being moved to a specified position, the control console 8 starts the servo motor 21. The servo motor 21 drives the worm 26 to rotate through the output shaft. The worm 26 drives the double-threaded rod 25 to rotate through the worm wheel 27 engaged therewith.

[0050] When the double-threaded rod 25 rotates, the nut sleeves 24 at the two ends of the double-threaded rod 25 move synchronously and in opposite directions along the double-threaded rod 25 in a threaded transmission mode. When the two nut sleeves 24 move relatively close to each other, the two nut sleeves 24 drive the first sliding blocks 18 to move relatively close to each other. The two first sliding blocks 18 make the bottom two links of the scissors linkage 3 close to each other, the scissors linkage 3 is elongated, and the operating table 6 is lifted up.

[0051] When the double-threaded rod 25 rotates, the main bevel gear 33 fixed coaxially with the double-threaded rod 25 rotates synchronously, the main bevel gear 33 drives the transmission rod 31 to rotate through the engaging of the secondary bevel gear 34, the transmission rod 31 drives the belt shaft groove wheel 37 to rotate through the universal shaft 35, and the belt shaft groove wheel 37 releases the wire; in the process of the operation table 6 rising, the steel wire 4 always exerts pulling force on the four corners of the operation table 6, when one side of the operation table 6 is too heavy, the pulling force of the steel wire 4 on the other side increases, so that the bending force on the scissors lever 3 decreases, thereby the connection of the scissors lever 3 is not easy to be damaged, and the safety of the working environment is improved; since the steel wire 4 is guided to pass through the middle rod 10 of the scissors lever 3 and is fixed on the bottom shell 1, and the steel wire 4 is in a taut state, the scissors lever 3 tends to be taut as a whole, thereby the ability of the scissors lever 3 to resist bending is further improved.

[0052] The lifting controllable mobile operation platform has the following advantages.

[0053] Firstly, the operation platform is provided with four belt shaft groove wheels and four steel wires, the four steel wires are connected with the four belt shaft groove wheels one by one, and the four steel wires are distributed at the four corners of the bottom of the operation table; in the process of the operation table rising, the steel wire always exerts pulling force on the four corners of the operation table, so that the operation platform is kept stable; when one side of the operation table is too heavy, the pulling force of the steel wire on the other side will automatically increase, so that the bending force on the scissors lever is reduced, the connection of the scissors lever is not easy to be damaged, and the problem that the operation platform tilts on one side is solved.

[0054] Secondly, the steel wire is guided through the first and second wire guide wheels, so that the steel wire is guided to pass through the middle rod of the scissors lever and is fixed on the bottom shell; since the steel wire is in a taut state, the scissors lever tends to be taut as a whole, thereby the ability of the scissors lever to resist bending is further improved.

[0055] Thirdly, the operation platform can not only straighten the outside, but also strengthen the scissors lever; the steel wire is arranged from one end of the operation table and is introduced into the middle rod of the scissors lever; with the rising of the operation table, the angle of the upper part of the steel wire changes, the contact area between the steel wire and the second wire guide wheel increases, the local force is reduced, and the service life of the steel wire is improved.

[0056] Fourthly, the operation platform has simple structure; the lifting of the scissors lever, the self-adaptive stability of the steel wire and the balance of the operation platform can be simultaneously completed through a single motor, and the operation platform does not need to be additionally provided with a storage winding structure, a motor and the like.

[0057] The above merely describes the embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent transformation or direct or indirect application in the related technical field based on the content of the present application specification and drawings is also included in the patent protection scope of the present application.
