DETAILED DESCRIPTION

[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail with reference to the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention. The technical solutions of the present invention will be described in detail below with reference to the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0023] like Figure 1 As shown in FIG. 4 , the present invention provides a single-pillar group transport device, including a front anchor support 2, a rear anchor support 3, a base 1, a push cylinder 4, a lifting assembly 5, a lateral moving assembly, and a support assembly 6.

[0024] The base 1 is a square plate-like structure extending along the front-to-back direction. A front anchoring support body 2 is provided on the front side of the base 1, and a rear anchoring support body 3 is fixedly provided on the front end of the upper end of the base 1. The front anchoring support body 2 and the rear anchoring support body 3 are connected by a push cylinder 4.

[0025] The front anchoring support body 2 includes a front base 7, a front crossbeam 9, and a front column 8. The front crossbeam 9 is located above the front base 7, and the front crossbeam 9 and the front base 7 are connected by a vertical front column 8.

[0026] The rear anchoring support body 3 includes a rear base 12, a rear cross beam 10, and a rear column 11. The rear base 12 is fixedly arranged on the front end of the upper end face of the base 1. The rear cross beam 10 is located above the rear base 12. The rear cross beam 10 and the rear base 12 are connected by a vertical rear column 11.

[0027] One end of the piston rod of the push cylinder 4 is connected to the front base 7 , and one end of the cylinder bottom of the push cylinder 4 is connected to the rear base 12 .

[0028] The front and rear edges of the lower end face of the front base 7 are inclined upward.

[0029] The front and rear edges of the lower end surface of the base 1 are inclined upward.

[0030] There are two lifting assemblies 5 , which are arranged front to back on the upper end surface of the base 1 .

[0031] Each lifting assembly 5 includes two lifting frames 13 , two lifting cylinders 14 , and two connecting plates 15 .

[0032] Each lifting frame 13 is a vertically mounted square box structure, arranged front and back on the upper surface of the base 1. The two lifting frames 13 are fixedly connected by two horizontal connecting plates 15, which are arranged vertically. A vertical lifting cylinder 14 is installed on the outside of each lifting frame 13. The bottom end of the lifting cylinder 14 is hinged to the upper surface of the base 1, and the piston rod of the lifting cylinder 14 is hinged to the outer side of the lifting frame 13.

[0033] Each lifting frame 13 is provided with two upper and lower lateral moving components, which correspond one-to-one to the upper and lower connecting plates 15. Each lateral moving component includes two telescopic cylinders 18, two swing connecting rods 19, a T-shaped block 17, a set of hook claws 20, and a guide rail 16.

[0034] Two horizontal telescopic cylinders 18 are located inside the adjacent end surfaces of the two lifting frames 13 on either side of the connecting plate 15. The upper connecting plate 15 is located between the upper two telescopic cylinders 18, and the lower connecting plate 15 is located between the lower two telescopic cylinders 18. One end of the cylinder bottom of the telescopic cylinder 18 is hinged to the interior of the lifting frame 13, and one end of the piston rod of the telescopic cylinder 18 extends outside the lifting frame 13 and toward the other lifting frame 13.

[0035] A guide rail 16 is fixedly mounted in the middle of the upper end surface of each connecting plate 15. A T-slot is disposed within guide rail 16. This T-slot is an inverted T-shaped structure, extending horizontally and connecting to the upper end surface and the left and right end surfaces of guide rail 16. A T-block 17 is slidably connected within the T-slot of guide rail 16. This T-block 17 is an inverted T-shaped structure, with its upper end extending beyond the T-slot. A set of hooking claws 20 are fixedly mounted on the upper end surface of T-block 17. Two hooking claws 20 are arranged horizontally within each set.

[0036] Each T-shaped block 17 is equipped with a swing link 19 at its front and rear ends. One end of each swing link 19 is hinged to the T-shaped block 17, and the other end is hinged to the piston rod ends of the front and rear telescopic cylinders 18. The hinge axes of the two swing links 19 remain vertical. When the telescopic cylinders 18 on both sides extend and retract synchronously, the two swing links 19 swing synchronously, thereby driving the T-shaped block 17 to slide left and right within the guide rail 16.

[0037] The support assembly 6 includes four single pillars 21, two fixing plates 22, and eight clamps 23. The four single pillars 21 are kept vertical and evenly arranged along the front-to-back direction. Two upper and lower horizontal fixing plates 22 are set on one side of the four single pillars 21. The two fixing plates 22 are in contact with the four single pillars 21. Each single pillar 21 is fixedly connected to the two fixing plates 22 through two U-shaped clamps 23. The clamps 23 and the fixing plates 22 are connected by bolts and nuts. The four single pillars 21 are fixedly connected to form a whole support assembly 6 through the clamps 23 and the fixing plates 22.

[0038] The working principle of the present invention is:

[0039] Before the group of single pillars 21 are moved, the support assembly 6 composed of the group of single pillars 21 is located on the base 1 and supported by the base 1. The guide rail 16 of the front lifting assembly 5 is located between the first single pillar 21 and the second single pillar 21, and the guide rail 16 of the rear lifting assembly 5 is located between the third single pillar 21 and the fourth single pillar 21. At this time, the lifting cylinder 14 is in a semi-extended state, and the lifting frame 13 is in an intermediate high position. At the same time, the telescopic cylinder 18 inside the lifting assembly 5 is in a semi-extended state, driving the T-shaped block 17 to extend to the outside of the guide rail 16. The upper fixed plate 22 inside the support assembly 6 is located inside the hook claws 20 above the two lifting assemblies 5, and the lower fixed plate 22 inside the support assembly 6 is located inside the hook claws 20 below the two lifting assemblies 5. The support assembly 6 is limited in the left and right directions by the T-shaped block 17 and the hook claws 20.

[0040] When the support assembly 6 needs to be placed, first control the entire device to move forward, control the front column 8 to retract, and control the rear column 11 to extend, at which time the rear crossbeam 10 is in contact with the top. Then control the push cylinder 4 to extend, driving the front anchor support 2 to move forward as a whole. Then control the front column 8 to extend, and control the rear column 11 to retract, at which time the front crossbeam 9 is in contact with the top, and the push cylinder 4 to retract, driving the base 1 and the rear anchor support 3 as a whole to move forward, and the lifting assembly 5 drives the support assembly 6 to move forward synchronously. Subsequently, the lifting cylinder 14 continues to extend, and the lifting frame 13 rises, driving the support assembly 6 to rise synchronously and separate from the base 1. Next, control the telescopic cylinder 18 to continue to extend, and the T-shaped block 17 continues to slide toward the outside of the guide rail 16, thereby driving the support assembly 6 to move outward as a whole, until the support assembly 6 is pushed out to above the preset support position. Next, the lifting cylinder 14 contracts, lowering the lifting frame 13 as a whole, driving the support assembly 6 downwards synchronously until the single support 21 contacts the roadway floor. The single support 21 stops descending, and the lifting cylinder 14 continues to contract, causing the lifting frame 13 to continue descending. The hook claw 20 disengages from the fixed plate 22 of the support assembly 6, placing the support assembly 6 on the roadway floor. The piston rod of the single support 21 extends to connect with the top for support. Subsequently, the telescopic cylinder 18 is controlled to retract, and the T-block 17 drives the hook claw 20 to retract toward the inside of the guide rail 16.

[0041] When support assembly 6 needs to be retracted, the piston rod of single support column 21 retracts, telescopic cylinder 18 extends, and T-block 17 drives hook claw 20 outward to below fixed plate 22. Lifting cylinder 14 extends, driving lifting frame 13 upward. Lifting frame 13 drives T-block 17 upward, and hook claw 20 contacts fixed plate 22. As lifting frame 13 continues to rise, T-block 17 drives support assembly 6 upward, and support assembly 6 disengages from the roadway floor. Next, telescopic cylinder 18 retracts, and T-block 17 slides toward the interior of guide rail 16. Support assembly 6 moves with T-block 17 toward lifting assembly 5 until support assembly 6 moves above base 1. Finally, lifting cylinder 14 retracts, lifting frame 13 descends, driving support assembly 6 downward with it until support assembly 6 contacts base 1, and support assembly 6 is retracted onto base 1.

[0042] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
