Problems solved by technology

Whether it is the initial lifting or mid-lifting, it is not only wasteful, but also the H-shaped steel web clamped by the jack in the horizontal direction, after several times of pulling, the roughness and deformation are very serious, which shortens the service life of the material and increases the cost

Embodiment Construction

[0022] Figure 1 ~ Figure 3 It is a structural schematic diagram of the H-shaped steel pile lifting machine of the present invention; Figure 4 ~ Figure 5 A schematic structural diagram of the wedge locking device is shown. Image 6 The locking blocks of the wedge locking device are arranged in pairs (or mutually locked, or mutually loosened).

[0023] It can be seen from the figure that the H-shaped steel pile lifting machine includes an upper frame body 7, a lower frame body 4, an initial lifting ring 2, a jacking jack 9 and a load-bearing support 1, which is characterized in that: the jacking The upper end of the lifting jack 9 passes through the steel sleeve and the large fixed guide frame 8 to be integrated with the upper frame body 7, and the lower end passes through the small fixed guide frame 11 set on the lower frame body 4, the steel sleeve and the bearing support 1 connected, and can pass through the steel sleeve of the lower frame body 4 to press down and extend ...

Abstract

The invention discloses an H-shaped steel pulling and lifting machine, solves the technical problems that galling and deformation easily occur and the damage is serious when an H-shaped steel pile is pulled and lifted, and belongs to the technical field of equipment for capital construction. According to the pulling and lifting machine disclosed by the invention, pulling and lifting jacks, locking jacks, initial pulling and lifting suspension rings and a wedged locking device are combined into a whole through an upper frame body and a lower frame body. The H-shaped steel pulling and lifting machine is characterized in that one ends of the locking jacks are connected with the upper frame body, the other ends of the locking jacks are connected with the lower frame body through locking jack supports, the spacing between the upper frame body and the lower frame body can be adjusted along with expansion and contraction of the locking jacks, locking blocks of the wedged locking device are wedged blocks with wide upper parts and narrow lower parts, and are arranged oppositely in pairs, and the corresponding locking blocks are locked or loosened along with the expansion and contraction of the locking jacks. The initial pulling and lifting suspension rings are used for initially pulling and lifting H-shaped steel; and the subsequent pulling and lifting of the H-shaped steel is realized in a way that the wedged locking device fully locks a flange and a web plate, so the galling and deformation damage of the H-shaped steel are reduced, and the service life of the H-shaped steel is prolonged.

Description

technical field [0001] The invention relates to an H-shaped steel pile pulling machine, in particular to a steel pile pulling machine for re-pulling an H-shaped steel pile implanted in the ground at the initial stage of a project, and belongs to the technical field of infrastructure engineering. Background technique [0002] In building construction, the SMW construction method can be applied to deep foundation pits with multiple supports, so it has great development prospects. In order to reduce the project cost, the H-shaped steel piles implanted in the ground during the construction of SMW construction method should be pulled out after their function is over, and then reused. [0003] At present, the initial lifting of H-shaped steel piles is carried out by means of a gantry combined with auxiliary devices and through a jack. In the middle of the lifting, the jack is first clamped separately in the horizontal direction, and then the jack is supported by the jack. Whether...
