Problems solved by technology

The whole needs to be moved down with the deepening of the foundation pit. The elevator is bulky and heavy. Now it mainly depends on hoisting to move it down separately and then assemble it, which is very time-consuming and labor-intensive.
Unfavorable effects such as difficulties in excavation and construction of building structures on foundation pit construction

Embodiment 1

[0054] This embodiment provides a kind of heavy-duty earth-lifting facility integral down-moving device, such as Figure 1 to Figure 5 As shown, the overall downward movement device is arranged between the heavy-duty soil lifting facility and the support beam 6, including the heavy-duty soil lifting facility support 1 for supporting the heavy-duty soil lifting facility, and the downward movement device arranged on the support beam 6. Institution 2. Wherein, the heavy-duty soil lifting facility support 1 includes several pillars 1.2 fixedly connected with the heavy-duty soil lifting facility circumferentially, and each pillar 1.2 is provided with several support bearing structures 1.1 along the vertical direction. The described down-moving mechanism 2 is several arranged circumferentially, and corresponds to the support load-bearing structure 1.1 of the pillar 1.2; each down-moving mechanism 2 includes a lifting device 2.3, and the bottom of the lifting device 2.3 is fixed on t...

Embodiment 2

[0069] The structure and principle of this embodiment are basically the same as Embodiment 1, the difference is that: Figure 6 and Figure 7 As shown, the frame bracket 2.1 is provided with a chute, and one side of the chute is provided with a load-bearing bracket 2.5, and the load-bearing shaft 2.2 is hinged with the load-bearing bracket 2.5 in the chute. In the process of adjusting one by one, the lifting device 2.3 of the down-moving mechanism 2 descends the first distance, so that the load-bearing shaft 2.2 is separated from the bottom of the original hanging claw, and then the load-bearing shaft 2.2 rotates out of the chute along the hinge point and moves to the outside to connect with the hanging claw. The place away from; then the lifting device 2.3 of the down-moving mechanism 2 rises the second distance, and the load-bearing shaft 2.2 rotates along the hinge point to the bottom of a hanging claw above the original hanging claw, and the lifting device 2.3 continues to...

Embodiment 3

[0071] The structure and principle of this embodiment are basically the same as Embodiment 1, the difference is that: Figure 8 As shown, the load-bearing structure 1.1 of the support is a hanging claw; wherein the moving part of the lifting device 2.3 is connected with the frame bracket 2.1, and the fixed part of the lifting device 2.3 is connected with the load-bearing support 3; the load-bearing shaft is connected with The load-bearing bracket 2.5 with the hanging claws interlocked, the load-bearing bracket 2.5 is hinged with the frame body bracket 2.1; 2.5 is directly hinged to the whole. The end of the load-bearing bracket 2.5 is connected to the fixed part of the lifting device 2.3 through the elastic element 2.6; On both sides of the hinge point with the frame bracket 2.1; the down-moving mechanism uses the jacking of the lifting device and the stretching of the elastic element to make the load-bearing bracket rotate around the hinge point with the frame bracket, so as...

Abstract

The present invention provides an overall downward movement device for heavy-duty soil lifting facilities, which is arranged between the heavy-duty soil lifting facilities and a supporting beam, and includes a heavy-duty soil lifting facility support for supporting the heavy-duty soil lifting facilities, and a The upper and lower moving mechanism; the heavy-duty soil lifting facility support includes several pillars fixedly connected with the heavy-duty soil lifting facility in the circumferential direction, and each pillar is provided with a number of support load-bearing structures along the vertical direction; the downward movement mechanism is a circumferential Several sets are provided, and correspond to the load-bearing structure of the pillar support; each down-moving mechanism includes a lifting device, the bottom of the lifting device is fixed on the support beam through a load-bearing support, and the top of the lifting device is provided with a frame bracket. A movable load-bearing shaft is arranged on the body bracket, and the heavy-duty soil lifting facility support is carried on the load-bearing shaft through the support force-bearing structure. The present invention realizes the rapid downward movement of the heavy-duty soil lifting facility as a whole, and can efficiently and stably ensure that the heavy-load soil lifting facility moves down to the set position of the foundation pit.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pits, and in particular relates to a device and method for integrally moving down heavy-duty soil lifting facilities. Background technique [0002] With the increasing speed of urban construction, high-rise and super high-rise buildings have become the main architectural forms of many central cities, and a large number of subway station buildings, high-rise and super high-rise structures have also appeared. As it gets deeper and deeper, considering the safety factor, it is more and more common to install internal supports in deep foundation pits. While ensuring the safety of foundation pits, the excavation efficiency of deep foundation pits is affected by the narrow environment of the inner and surrounding areas, and the problem of earthwork transportation has seriously affected foundation pits. Construction Schedule. [0003] At present, earthwork transportation is mainly realized by set...
