Description

Technical Field

[0001] The utility model belongs to the field of building structure construction, in particular to a large steel structure sliding and pushing hydraulic crawler. Background Art

[0002] With the rapid development of my country's economy, large-scale construction projects are increasing. The installation of some large components has put forward higher requirements on construction technology. Relying on traditional construction technology and equipment is far from meeting the requirements of high technical difficulty, large engineering volume and short construction period in modern engineering construction. Hydraulic synchronous sliding is a new technology developed under this background. It is mainly used for the horizontal displacement of large components. It integrates mechanical, electronic, computer, communication and control theory, and can achieve precise synchronous horizontal sliding.

[0003] The hydraulic synchronous sliding system in the prior art generally adopts a rail-type linear sliding, and controls the crawler to push the hydraulic telescopic cylinder through a computer, and relies on the crawler's wedge-shaped self-locking device to clamp or release the track, so that the structure is synchronously pushed forward along the track to achieve the sliding installation of large structural units. The applicant has found that the hydraulic synchronous sliding system in the prior art has at least the following technical problems: There is sliding friction between the wedge-shaped self-locking device and the track in the currently used rail-type linear sliding system, and long-term use will cause the track to wear and deform. At the same time, when the hydraulic telescopic cylinder drives the wedge-shaped self-locking device to slide, the friction between the wedge-shaped self-locking device and the track is large, resulting in slow movement of the wedge-shaped self-locking device, which reduces the sliding and pushing efficiency of large steel structures. Utility Model Content

[0004] In view of the above problems in the prior art, the utility model aims to provide a large steel structure sliding and pushing hydraulic crawler, which solves the problem of track wear and deformation caused by long-term use of the hydraulic synchronous sliding system in the prior art.

[0005] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is as follows:

[0006] A large-scale steel structure sliding and pushing hydraulic crawler is provided, which includes a track arranged on a base plate, a clamping device and a sliding member are slidably arranged on the track, and a hydraulic cylinder is arranged between the clamping device and the sliding member; the clamping device includes a mounting box, the mounting box is in a "door"-shaped structure, and a plurality of first balls for rolling contact with the top wing plate of the track are arranged on the inner top of the mounting box; the sliding member includes a base that slides with the top wing plate of the track, and a connecting plate is arranged on the upper end surface of the base; the two ends of the hydraulic cylinder are respectively hinged to the mounting box and the connecting plate.

[0007] The basic principle of the hydraulic crawler for sliding and pushing large steel structures in the utility model is as follows: when sliding and pushing large steel structures, first place the large steel structures on the base, then hinge the two ends of the hydraulic cylinder with the installation box in the clamping device and the connecting plate in the sliding member, then clamp and fix the clamping device with the track, then extend the hydraulic cylinder, push the sliding member and the large steel structure on it, and start sliding forward. The hydraulic cylinder extends one stroke, and the large steel structure slides forward a distance; after one stroke, the sliding member does not move, the clamping device is relaxed, and the crawler hydraulic cylinder shrinks and drags the clamping device to slide forward; after one stroke, the clamping device is dragged to slide forward a distance, and one crawling and pushing stroke is completed. The hydraulic cylinder repeatedly extends and shrinks the cylinder multiple times to make the large steel structure slide to the final position.

[0008] In the utility model, the friction between the clamping device and the sliding member and the track is rolling friction. Compared with the prior art, it can not only reduce the wear of the track, avoid deformation of the track, and protect the track, but also make the clamping device and the sliding member move more smoothly, avoid jamming, and improve the sliding pushing efficiency of large steel structures.

[0009] Furthermore, as a specific setting scheme in which both ends of the hydraulic cylinder are respectively hinged to the installation box and the connecting plate, a connecting seat is provided on one side of the installation box and the connecting plate, and both ends of the hydraulic cylinder are respectively hinged to the two connecting seats through pins.

[0010] Furthermore, the base is in a "door"-shaped structure, and a plurality of second balls for rolling contact with the upper end surface of the top wing plate of the track are fixedly provided on the inner top surface of the base.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: the utility model provides a large steel structure sliding and pushing hydraulic crawler, and the friction between the clamping device and the sliding member and the track is rolling friction. Compared with the prior art, it can not only reduce the wear of the track and protect the track, but also make the clamping device and the sliding member move more smoothly, avoid jamming, and improve the sliding and pushing efficiency of large steel structures.

Preferably, but not limited to, as a specific setting scheme in which the two ends of the hydraulic cylinder 5 are respectively hinged to the installation box 301 and the connecting plate 402, a connecting seat 7 is provided on one side of the installation box 301 and the connecting plate 402, and the two ends of the hydraulic cylinder 5 are respectively hinged to the two connecting seats 7 through a pin shaft 8.
