Description

Technical Field

[0001] The utility model relates to the field of large-span building structure construction, and more specifically to large-span building structure hydraulic push-in-place construction equipment. Background Art

[0002] Large-span building structures refer to steel structures with larger spans, which are usually used in large buildings such as airports, railway stations, and gymnasiums. Large-span building structures are usually assembled on the ground, and then the assembled building structures are pushed to the designated position by hydraulic pushers for the next step of splicing.

[0003] In the prior art, in order to enable the hydraulic push device to push the building structure a longer distance, the hydraulic assembly in the prior device can change the flow direction of the hydraulic oil to move itself in the direction of the building structure after completing one push. However, when the hydraulic assembly moves, it will be slightly lifted and temporarily separated from the slide rail due to the reaction force of the slide rail. At this time, the building structure is only pressed on the top surface of the slide rail. If the slide rail has an inclined angle at this time, the building structure is easy to slide relative to the slide rail, resulting in derailment, which poses a hidden danger to movement safety.

[0004] Therefore, in order to solve the above problems, a large-span building structure hydraulic push-in-place construction equipment is proposed. Utility Model Content

[0027] Example:

[0028] See also Figure 1 - Figure 4 The large-span building structure hydraulic pushing construction equipment comprises two slide rails 1 and two hydraulic devices 2. The two hydraulic devices 2 are respectively fixed on the top of the two slide rails 1. The top surfaces of the two slide rails 1 are slidably provided with clamping plates 3. The two clamping plates 3 are symmetrically arranged. A fixed box 4 is arranged on the side of the clamping plate 3 close to the hydraulic equipment 2. A clamping mechanism is arranged inside the fixed box 4. The clamping mechanism comprises a gear 51 rotatably connected to the top surface of the inner wall of the fixed box 4 and two sliding blocks 52 slidably arranged inside the fixed box 4. The two sliding blocks 52 are symmetrically arranged inside the fixed box 4. A No. 1 rack 522 is fixedly connected to one side of the two sliding blocks 52 close to the gear 51. The two No. 1 racks 522 are respectively meshed on both sides of the gear 51. An extrusion sheet 53 is fixedly connected to one side of the two sliding blocks 52 close to the gear 51. The two extrusion sheets 53 are respectively slidably connected to both sides of the slide rail 1.

[0029] Specifically, the clamping mechanism further includes a hydraulic rod 54 fixedly connected to the top surface of the inner wall of the fixed box 4 , and a second rack 55 is fixedly connected to the telescopic end of the hydraulic rod 54 , and the second rack 55 is meshed with the gear 51 .

[0030] In this solution, the hydraulic device 2 can push the building structure on the slide rail 1 for a certain distance. After reaching the limit distance, the staff changes the working mode of the hydraulic device 2 through the external control component, so that the hydraulic cylinder part of the hydraulic device 2 can move along the slide rail 1 toward the building structure, so that the building structure can continue to be pushed in the next pushing work. This is the prior art;

[0031] Before pushing the large-span building structure, the staff can adjust the distance between the two slide rails 1 to adjust the distance between the two clamping plates 3, so that the two clamping plates 3 clamp the large-span building structure. After placing the building structure on the clamping plates 3 and completing the clamping, the staff turns on the hydraulic rod 54 to make the No. 2 rack 55 drive the gear 51 to rotate, so that the two No. 1 racks 522 approach each other, and then drive the extrusion plate 53 through the two sliding blocks 52 to clamp the two sides of the slide rail 1, thereby increasing the friction between the building structure and the slide rail 1 in disguise, improving the stability between the building structure and the slide rail 1, and preventing relative sliding between the building structure and the slide rail 1.

[0032] See also Figure 1 - Figure 3 Guide holes 41 are formed on both sides of the fixed box 4 , and a guide rod 56 is fixedly connected to the side of the sliding block 52 away from the slide rail 1 , and the guide rod 56 is slidably connected to the guide hole 41 .

[0033] Specifically, the end of the guide rod 56 away from the sliding block 52 is fixedly connected to a limiting piece 57 . The limiting piece 57 is arranged outside the fixed box 4 . The diameter of the limiting piece 57 is greater than the diameter of the guide hole 41 .

[0034] In this solution, the guide rod 56 cooperates with the guide hole 41 to play a guiding and limiting role, so that the sliding block 52 can slide more smoothly. The limiting plate 57 cannot pass through the guide hole 41, and can limit the sliding distance of the sliding block 52 toward the slide rail 1, preventing the hydraulic rod 54 from losing control and causing the sliding block 52 to continue to tighten inward, thereby protecting the slide rail 1.

[0035] See also Figure 1 - Figure 4 Both sides of the clamping plate 3 are threadedly connected with fixing bolts 6, and the clamping plate 3 is fixedly connected to the fixing box 4 by the fixing bolts 6 arranged thereon. In this solution, the fixing bolts 6 can facilitate the staff to install and disassemble the clamping plate 3 and the fixing box 4.

[0036] See also Figure 1 and Figure 4 A limiting groove 11 is provided at the top of the slide rail 1, and the bottom of the clamping plate 3 is rotatably connected to a limiting wheel 7, which is arranged inside the limiting groove 11. In this solution, the limiting wheel 7 can ensure that the clamping plate 3 can always move directly above the slide rail 1 during transportation of the building structure, thereby avoiding the tipping over of the building structure during movement.

[0037] Working principle: Before pushing the large-span building structure, the staff can adjust the distance between the two sliding rails 1 to adjust the distance between the two clamping plates 3, so that the two clamping plates 3 clamp the large-span building structure. After placing the building structure on the clamping plates 3 and completing the clamping, the staff turns on the hydraulic equipment 2 to push the building structure. After the hydraulic equipment 2 pushes to the limit distance, the staff controls the working mode of the hydraulic equipment 2 to make the hydraulic cylinder part of the hydraulic equipment 2 slide toward the direction of the building structure. During this process, the staff turns on the hydraulic rod 54, drives the gear 51 to rotate through the No. 2 rack 55, and cooperates with the two No. 1 racks 522 to make the two sliding blocks 52 drive the extrusion plates 53 to clamp the two sides of the slide rail 1, thereby increasing the friction between the building structure and the slide rail 1 in disguised form, improving the stability between the building structure and the slide rail 1, and preventing relative sliding between the building structure and the slide rail 1.

[0038] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
