Problems solved by technology

The lifting equipment is equipped with a lifting platform. The earth truck transports the earthwork in the foundation pit to the ground through the lifting platform. Its installation is all spliced ​​and aligned on site and then welded into a whole. For deep excavation, the overall downward movement mainly depends on the lifting method to separate and move them down, and then assemble and weld them. The cumbersome

Example Embodiment

[0035] Example one:

[0036] The present invention provides a heavy-duty carrying equipment, such as Figure 1 to Figure 4 As shown, it includes a skeleton attachment structure, an overall downward movement device and a heavy-duty soil lifting facility.

[0037] The skeleton attachment structure is composed of the lower bearing pile frame structure 1.1 and the top support structure 1.2. The top support structure 1.2 is detachably connected to the lower bearing pile frame structure 1.1 in a circumferential direction, and will be disassembled and turned over after the project ends.

[0038] The overall downward movement device is arranged between the top support structure 1.2 and the heavy-duty soil lifting facility, and includes multiple sets of downward movement mechanisms 2 assembled on the top support structure 1.2. See the patent application CN201911029544.X for the detailed structure of the overall downward movement device.

[0039] The heavy-duty soil lifting facility includes a...

Example Embodiment

[0056] Embodiment two:

[0057] The principle and structure of this embodiment are similar to the first embodiment, and the difference lies in: Image 6 with Figure 7 As shown, the downward movement mechanism 2 includes an upper support 2.1 (equivalent to a frame bracket), a downward movement cylinder 2.2 (or other lifting devices), a lower support 2.3 (equivalent to a bearing support), and a bearing shaft 2.5 . The upper and lower supports are provided with oblique oblong holes 2.4, and each oblique oblong hole 2.4 is provided with the load bearing shaft 2.5. The position of the oblique oblong hole 2.4 is such that when the bearing shaft 2.5 is located in the lower half of the support structure 3.1.1, when the load bearing shaft 2.5 is located in the upper half of the oblique oblong hole 2.4, it matches the support structure 3.1. 1 Depart from the loading. The bearing shaft 2.5 can be automatically located at the bearing point after being converted into the long circular hole...

Abstract

The invention provides heavy-duty carrying equipment and a construction method. A framework attachment structure comprises a lower force-bearing pile frame structure and a top support structure; the top support structure is detachably and circumferentially connected onto the lower force-bearing pile frame structure; an overall downward-moving device is arranged between the top support structure and a heavy-duty soil lifting device; the heavy-duty soil lifting device comprises a peripheral framework structure, a car system, a main body lifting system and an electric control system; the peripheral framework structure comprises a bottom supporting beam frame and standard knots detachably connected onto the bottom supporting beam frame; the standard knots are stacked and connected according tothe depth of a support project; support force-bearing structures on the outer sides of the standard knots are matched with downward-moving mechanisms; and through rising and falling of a lifting device and carrying of a bearing shaft and the support force-bearing structures, overall downward movement of the heavy-duty soil lifting device is realized. According to the heavy-duty carrying equipmentand the construction method, the equipment can be used repeatedly in different foundation pit projects in a circulating manner, so that the economic efficiency and the environment-friendliness of soil lifting equipment are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of deep foundation pits, and in particular relates to heavy-duty carrying equipment and a construction method thereof. 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, the application of inner braces in deep foundation pits is becoming more and more common. When ensuring the safety of foundation pits, the excavation efficiency of deep foundation pits will be affected by the narrowness of the inner and surrounding environment. The problem of earthwork transportation in foundation pits It has seriously affected the progress of foundation pit construction. [0003] At present, earthwork transportation is mainly...
