Embodiment 1

[0044] Embodiment 1: a kind of foundation pit column pile, as figure 2 As shown, it includes a lower pillar 2 and an upper pillar 1 slidingly connected with the lower pillar 2; Threaded connection; the lower pillar 2 is provided with a cavity for placing the lifting screw 11; the side wall of the upper pillar 1 is fixedly connected with a fixed sleeve 12, and the fixed sleeve 12 is provided with a connecting hole 13 symmetrically about the axis.

[0045] When the foundation pit column pile is in use, the large gear 21 is rotated, so that the lifting screw 11 moves in the direction of the downward column 2, thereby driving the upper column 1 to move downward to the column 2, so that the upper column 1 and the lower column 2 are connected into one; The lower pillar 2 is buried below the ground, and the large gear 21 at the top of the upper pillar 1 and the lower pillar 2 is positioned above the ground.

[0046] When dismantling, hoist the upper pillar 1 with a sling, and limit...

Embodiment 2

[0047] Embodiment 2: a kind of removal device, such as figure 1 and image 3 As shown, it includes a fixed block 3 and a removal frame 4 arranged on the top of the fixed block 3; the removal frame 4 is symmetrically arranged on the top of the fixed block 3 with respect to the center of the fixed block 3; the fixed block 3 is provided with an insertion hole 31 for placing the lower pillar 2 One side of the insertion hole 31 communicates with the fixing block 3, and the cross section of the insertion hole 31 is "U"-shaped.

[0048] When in use, push the fixing block 3 so that the lower pillar 2 is inserted into the insertion hole 31 on the fixing block 3, so that the removal frame 4 is connected with the fixing sleeve 12 on the upper pillar 1, thereby facilitating the support of the upper pillar 1, thereby It is convenient to disassemble the upper pillar 1 .

[0049] The insertion hole 31 is slidingly connected with a closed plate 33 near the opening, and a closed cylinder 331 i...

Abstract

The invention discloses a foundation pit erect column pile and a dismantling device thereof, and relates to the field of house building foundation pit enclosures. The foundation pit erect column pilecomprises an upper erect column and a lower erect column, the upper erect column is vertically and slidably connected with the lower erect column, the top end of the lower erect column is lower erectcolumn is rotationally connected with a big gear wheel, and the bottom end of the upper erect column is fixedly connected with a lifting threaded rod; the big gear wheel is rotated, thereby making thelifting threaded rod rise, making the upper erect column rise, making the upper erect column separated from the lower erect column, and dismantling the upper erect column; the dismantling device comprises a fixing block, a dismantling frame and a drive motor; a patchhole is formed in the fixing block, the drive motor comprises an output shaft, and the output shaft of the drive motor is fixedly connected with a pinion; the dismantling frame is rotationally connected with a rotating block; the rotating block is fixed with a fixing sleeve, the drive motor drives the pinion to rotate, thereby dismantling the upper erect column; and the fixing block is moved, thereby transporting the upper erect column, and providing convenience for placing and transporting the upper erect column.

Description

technical field [0001] The invention relates to the field of house construction foundation pit enclosure, and more specifically relates to a foundation pit upright pile and a removal device thereof. Background technique [0002] Housing construction engineering refers to all kinds of housing construction and its ancillary facilities, as well as the supporting lines, pipelines, and equipment installation projects. During the construction of foundation pits, support measures are taken in the foundation pits to ensure construction safety. [0003] The prior art can refer to the Chinese utility model patent whose authorized announcement number is CN205591216U, which discloses a maintenance device for building foundation pits, including an upper column and a lower column; the bottom end of the upper column is fixedly connected with a connecting column, and the Fixing strips are set on both sides, and an upper chute is set on one side of the upper column. A slide plate is set in t...
