[0031] Reference Figure 1-Figure 10 As shown, this embodiment provides a lifting type processing platform, including:

[0032] The bottom support plate 5 has a lifting mechanism 2 fixedly connected in the middle of the bottom support plate 5. The lifting mechanism 2 includes two lifting components symmetrically arranged. The lifting component includes a base 201. The base 201 is fixedly connected to the top surface of the bottom support plate 5. The base 201 is rotatably connected with a double support rod 212 and a hydraulic rod 213 respectively.

The tops of the single pull rod 231 and the double pull rod 232 are rotatably connected with a top seat 241. The top of the top seat 241 is fixedly connected with a middle support plate 8. The middle of the inner side of the double pull rod 232 is rotatably connected with the hydraulic rod 213. The middle of the outer side of the double pull rod 232 is rotatably connected with a double middle rod 233.

A top support plate 741 is fixedly connected to the middle of the second movable slot plate 742, and large gears 733 are rotatably connected to the sides of the two ends of the top support plate 741, and a brake assembly is installed on any large gear 733. The small gear 702, the auxiliary gear and the large gear 733 are all meshed and linked with the chain 750.

[0034] The bottom support plate 5 provides support for the lifting mechanism 2. When the platform 3 needs to be lifted, the hydraulic rod 213 is extended, the bottom of the hydraulic rod 213 and the base 201 begin to rotate, and the hydraulic rod 213 drives the top double tie rod 232. The bottom of the double tie rod 232 pulls the double tripod 221 and rotates with the double tripod 221. The top of the double tie rod 232 pushes the top seat 241 and rotates with the top seat 241. The double tie rod 232 rotates with the middle of the double tripod 221. Then, the double tripod 221 is pulled by the double pull rod 232, and the double tripod 221 drives the single pull rod 231 connected to the top corner to move, the top of the single pull rod 231 and the top seat 241 rotate, the middle corner of the double tripod 221 rotates with the middle of the double support rod 212, the top of the double support rod 212 rotates with the bottom of the double middle rod 233, and the top of the double middle rod 233 rotates with the middle of the double pull rod 232, wherein the double support rod 212 limits the double tripod 221. The upper seat 241 pushes the middle support plate 8 to rise, thereby lifting the platform 3; when it needs to be lowered, the hydraulic rod 213 contracts, which is opposite to the action in the lifting state; by setting multiple rods, the double triangular bracket hydraulic rod 213, the rotation between the upper seat 241 and the base 201, the space occupied by the lifting can be reduced, so that the platform 3 can be lowered to a lower height than the screw lifting device and the vertical hydraulic rod 213 lifting device, and the use scenario of the bottom platform 3 operation can be realized; by setting two lifting mechanisms 2, the platform 3 can be stably lifted and lowered; the bottom plate 701 set on the middle support plate 8 can provide space for the setting of the small gear 702 and the large gear 733, the top surface of the top support plate 741 is flush with the top surface of the second movable groove plate 742, the top surface of the top support plate 741 and the top surface of the second movable groove plate 742 are jointly fixed with the platform 3, and mechanical processing operations can be performed on the platform 3;When the platform 3 is pushed in any direction of the four corners of the middle support plate 8, the first movable slot plate 721 slides on the first fixed slot plate 711, the fixed support plate 722 slides with the first movable slot plate 721, the second movable slot plate 742 slides on the second fixed slot plate 735, and the top support plate 741 fixed on the second fixed slot plate 735 slides with the second fixed slot plate 735. The large gears 733 arranged at both ends of the side of the top support plate 741 are arranged diagonally symmetrically. The large gear 733 extends downward to below the bottom surface of the second fixed slot plate 735 through an extension frame fixed to the side of the top support plate 741. The chain 750 is subjected to the displacement of the auxiliary gear and the large gear 733 and meshes and rotates on the small gear 702, the auxiliary gear and the large gear 733. When pushed to the desired position, the brake assembly restricts the rotation of any large gear 733, and the restricted large gear 733 restricts the meshing rotation of the chain 750, and the chain 750 restricts the other large gear 733, the auxiliary gear and the small gear The rotation of the gear 702 realizes the fixing of the platform 3 at the desired position, and avoids the influence of the external force displacement on the processing accuracy of the platform 3. The second fixed slot plate 735 is provided with limit blocks 736 on both sides, wherein the limit block 736 on one side is located above any auxiliary gear of a fixed support plate 722, and the limit block 736 on the other side is located above the auxiliary gear diagonally opposite to the auxiliary gear in the other fixed support plate 722 and the previous fixed support plate 722. The second limit plates 732 are fixedly connected to the ends of the two side surfaces of the top support plate 741, and the two second limit plates 732 at both ends are respectively located on the opposite sides of the large gears 733 at both ends. When the second movable slot plate 742 drives the top support plate 741 to slide on the second fixed slot plate 735 to a certain distance, the second limit plate 732 contacts the limit block 736, limiting the sliding length of the second movable slot plate 742 on the second fixed slot plate 735, so as to prevent the second movable slot plate 742 from detaching from the second fixed slot plate 735. ;

[0035] According to a further optimized solution, a single support rod 211 is rotatably connected inside the base 201 , and the top of the single support rod 211 is rotatably connected to the double tripod 221 .

[0036] The top of the single support rod 211 is rotatably connected to the bottom angle of the double tripod 221, so that during the lifting process, the top seat 241 can move the middle support plate 8 more stably in the horizontal direction.

[0037] To further optimize the solution, first limiting plates 712 are fixedly connected to both ends of the top surface of the first fixed slot plate 711 , and two supporting wheels 713 are rotatably connected to the first limiting plate 712 . The supporting wheels 713 are rotatably connected to the bottom surface of the second movable slot plate 742 .

[0038] The first limiting plate 712 is used to limit the sliding of the first movable slot plate 721 on the first fixed slot plate 711 to prevent the first movable slot plate 721 from separating from the first limiting plate 712 when sliding. The supporting wheel 713 is used to support the second movable slot plate 742 to increase the supporting stability when the platform 3 moves.

[0039] To further optimize the solution, pulleys 734 are installed at both ends of the bottom surface of the second fixed groove plate 735, and the pulleys 734 are rotatably connected to the top surface of the middle support plate 8.

[0040] The pulleys 734 installed at both ends of the bottom of the second fixed slot plate 735 can rotate 360° to meet the lateral and longitudinal movement of the second fixed slot plate 735. The pulleys 734 provide support for the second fixed slot plate 735 and provide support for the platform 3 when moving, making the movement of the platform 3 more stable.

[0041] To further optimize the solution, the brake assembly includes a brake pad 764, which is fixedly connected to the large gear 733, and friction plates 761 are respectively contacted and connected on both sides of the brake pad 764, and positive and negative thread adjustment screws 762 are symmetrically threaded on the two friction plates 761, and driving motors 763 are respectively installed at the bottom of the two positive and negative thread adjustment screws 762, and the driving motor 763 is fixedly connected to the side of the top support plate 741.

[0042] When braking is needed, the two driving motors 763 rotate, driving the forward and reverse wire adjusting screws 762 to rotate, and the forward and reverse wire adjusting screws 762 drive the two friction plates 761 to clamp the brake pads 764. The brake pads 764 are restricted from rotating, and the large gear 733 fixed to the brake pads 764 is also restricted from rotating. The chain 750 meshing with the large gear 733 cannot rotate. The chain 750 restricts the rotation of another large gear 733, the auxiliary gear and the small gear 702, thereby fixing the platform 3 at the desired position.

[0043] According to a further optimized solution, a positioning telescopic rod 6 is symmetrically fixed to the top surface of the bottom support plate 5 , and the top of the positioning telescopic rod 6 is fixed to the bottom surface of the middle support plate 8 .

[0044] The positioning telescopic rod 6 will passively follow the lifting and lowering of the platform 3 to be unfolded or retracted, and is used to assist in limiting the horizontal movement of the middle support plate 8, making the lifting process more stable.

[0045] According to a further optimized solution, the top surface of the bottom support plate 5 is fixedly connected with the telescopic box 1 , the top surface of the telescopic box 1 is fixedly connected with the bottom surface of the middle support plate 8 , and the positioning telescopic rod 6 is located inside the telescopic box 1 .

[0046] The telescopic box 1 will passively unfold or retract following the lifting of the platform 3, so as to strengthen and assist in limiting the horizontal movement of the middle support plate 8 and protect the internal structure at the same time.

[0047] To further optimize the solution, universal wheels 4 are installed at the four corners of the bottom surface of the bottom support plate 5.

[0048] The universal wheels 4 installed at the bottom can facilitate the movement of the processing platform.
