[0027] Embodiment 1: A transport platform lifting device comprises a deck body 1, two intermediate transverse guide rails 2 are symmetrically arranged on the top of the deck body 1, two intermediate longitudinal guide rails 3 are symmetrically arranged at both ends of the intermediate transverse guide rails 2, side guide rails 4 are arranged at the diagonals of the ends of the intermediate transverse guide rails 2 and the intermediate longitudinal guide rails 3, and four transverse guide rail lifting assemblies 5 and a longitudinal guide rail lifting assembly 6 are arranged on the deck body 1.

[0028] The transverse guide rail lifting assembly 5 includes a lifting movable groove 501 opened at the top of the deck body 1, and the lifting movable groove 501 is respectively located directly below the two middle transverse guide rails 2 and the two middle longitudinal guide rails 3. The bottom wall of the lifting movable groove 501 is opened with a cylinder mounting groove 502, and a first electric hydraulic cylinder 503 is arranged in the cylinder mounting groove 502. A pushing connecting plate 504 is slidingly arranged in the lifting movable groove 501, and two abutting push rods 505 are symmetrically arranged on both sides of the top of the pushing connecting plate 504. The top of the abutting push rod 505 is respectively connected to the two sides of the bottom of the middle transverse guide rail 2 and the middle longitudinal guide rail 3.

[0029] The longitudinal guide rail lifting assembly 6 includes four top wall mounting grooves 601 opened at the top of the deck body 1. The top wall mounting grooves 601 are all located directly below the side guide rails 4. A second electric hydraulic cylinder 602 is installed in the top wall mounting grooves 601. The bottom ends of the side guide rails 4 are all provided with guide rail connecting plates 603. The top ends of the second electric hydraulic cylinders 602 are fixedly connected to the bottom ends of the guide rail connecting plates 603.

[0030] Embodiment 2: The difference between this embodiment and embodiment 1 is that, the bottom wall of the lifting movable groove 501 is symmetrically provided with two limiting rods 506 , and the top ends of the limiting rods 506 both penetrate the pushing connecting plate 504 .

[0031] This makes the push connecting plate 504 more stable when being pulled up and down by the first electric hydraulic cylinder 503 .

[0032] Embodiment 3: The difference between this embodiment and embodiment 1 is that two side wall limit grooves 507 are symmetrically opened on both sides of the inner wall of the lifting movable groove 501, and two side wall limit blocks 508 are symmetrically arranged at the end of the pushing connecting plate 504, and the side wall limit blocks 508 are slidably inserted in the side wall limit grooves 507.

[0033] This makes it more stable when the connecting plate 504 is pushed to slide up and down in the lifting movable groove 501 .

[0034] Embodiment 4: The difference between this embodiment and embodiment 1 is that, a limit hole 604 is provided on the guide rail connecting plate 603, a limit column 605 is inserted through the limit hole 604, and the bottom end of the limit column 605 is fixedly connected to the top surface of the deck body 1.

[0035] This makes it more stable when the second electric hydraulic cylinder 602 pushes the guide rail connecting plate 603 up and down and is limited by the limiting column 605.

[0036] In this embodiment, since most of the existing guide rails for transport platforms are directly fixed and laid at specific positions on the clamping plates, the guide rails cannot be effectively raised and lowered, and different guide rails cannot be replaced and connected, which makes it inconvenient for users to change tracks and move the transfer vehicles running on the guide rails, resulting in inconvenience in the transportation of scientific research equipment.

[0037] In summary, in the specific implementation, by arranging the middle transverse guide rail 2, the middle longitudinal guide rail 3 and the side guide rail 4 above the deck body 1, the moving wheels arranged at the bottom of the transport platform arranged thereon can be limited and guided, thereby making the transportation of scientific research equipment more stable and convenient, and by arranging the transverse guide rail lifting assembly 5 at the bottom of the middle transverse guide rail 2 and the middle longitudinal guide rail 3, when the first electric hydraulic cylinder 503 in the transverse guide rail lifting assembly 5 is started synchronously, it can push the connecting plate 504.

[0038] The pushing connecting plate 504 is used to synchronously push the middle transverse guide rail 2 or the middle longitudinal guide rail 3 upward through the resistance push rod 505, thereby realizing the lifting and lowering height adjustment of the middle transverse guide rail 2 or the middle longitudinal guide rail 3, and the pushing connecting plate 504 is limited by the limit plug rod 506 inserted through it, and the two ends of the pushing connecting plate 504 slide in the side wall limit groove 507 through the set side wall limit block 508, thereby making the pushing connecting plate 504 more stable in pushing the resistance push rod 505 up and down, and can keep the two middle transverse guide rails 2 or the two middle longitudinal guide rails 3 moving synchronously on the same horizontal plane, so that the middle transverse guide rail 2 or the middle longitudinal guide rail 3 can be lifted and lowered more accurately and stably.

[0039] The second electric hydraulic cylinder 602 in the longitudinal guide rail lifting assembly 6 can appropriately lift and lower the height of the side guide rail 4 set on the top of the guide rail connecting plate 603 by pushing the guide rail connecting plate 603. A limiting hole 604 is provided on the side of the guide rail connecting plate 603, and a limiting column 605 is inserted through the limiting hole 604. The limiting column 605 can effectively limit the up and down movement of the guide rail connecting plate 603, so that the side guide rail 4 can move up and down while maintaining the horizontality under the push of the second electric hydraulic cylinder 602, and can more effectively adjust the up and down lifting of the middle transverse guide rail 2, the middle longitudinal guide rail 3 and the side guide rail 4, so that different guide rails can be connected more conveniently, which is beneficial to the track changing movement of the transfer vehicle on the guide rail and the transportation and use of scientific research equipment.
