Description

Technical Field

[0001] The utility model relates to the technical field of foundation pit support, in particular to a foundation pit support safety removal device. Background Art

[0002] Foundation pit support refers to a series of support, reinforcement and protection measures taken around deep foundation pits during the construction process to ensure the safety of the environment around the foundation pit and the stability of the soil, while ensuring the safe construction of underground structures. Common forms of foundation pit support include: pile support, pile support, pile anchor, pile cantilever; underground continuous wall support, ground-connected wall + support; cement retaining wall; soil nail wall (sprayed anchor support); reverse arch wall; original soil slope; pile, wall and support system; simple horizontal support; reinforced concrete piles. In short, foundation pit support plays a vital role in construction, ensuring the safety and smooth progress of the construction process, while reducing the impact on the external environment.

[0003] Among them, when the main structure and wall surface in the foundation pit are completed, the cement retaining wall and cement piles temporarily built inside the foundation pit support need to be demolished in order to carry out subsequent construction of the main structure and wall surface inside the foundation pit.

[0004] However, when the prior art is actually used, during the process of demolishing the temporary cement retaining walls and cement piles inside the foundation pit support, the foundation pit support is usually demolished manually by using a breaker hammer inside the foundation pit. However, when the foundation pit support is demolished manually by using a breaker hammer inside the foundation pit, high-frequency vibrations are easily generated during the demolition process using the breaker hammer, which leads to the risk of falling gravel or soil during the demolition construction inside the foundation pit.

However, when the foundation pit support is dismantled inside the foundation pit manually using a breaker hammer, high-frequency vibration is easily generated during the dismantling process using the breaker hammer, which leads to the risk of falling gravel or soil during the dismantling construction inside the foundation pit.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: comprising a suspension top plate, wherein the upper end surface of the suspension top plate is fixedly installed with hanging rings at the four corners, the middle part of the upper end surface of the suspension top plate is fixedly installed with a mounting platform, the upper end and the front end of the mounting platform are respectively fixedly installed with a first limiting slide rail, the middle part of the first limiting slide rail is limitedly slidably connected with a first limiting slide buckle, the outer end of the first limiting slide buckle is fixedly installed with an L-shaped moving plate, the rear side of the upper end of the L-shaped moving plate is fixedly installed with a first reduction motor, the rear end transmission shaft part of the first reduction motor is fixedly installed with a first transmission gear, and the lower end of the first transmission gear is meshingly connected with a first transmission rack;

Guide rings are fixedly installed on both sides of the suspension top plate, and there are four guide rings, which are symmetrically distributed at both sides of the suspension top plate.

[0009] Preferably, there are two first limiting slide rails, which are horizontally distributed at the upper end and the front end of the mounting platform respectively.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model has two fixedly installed breakers for dismantling the foundation pit support on both sides of the lower top of the telescopic arm, and the number of the breakers is symmetrically distributed on both sides of the lower top of the telescopic arm, so that when the suspension top plate is suspended inside the foundation pit, the foundation pit support inside the foundation pit can be dismantled by the breakers, avoiding the role of manual dismantling of the foundation pit support inside the foundation pit, thereby achieving the role of installation and dismantling of the foundation pit support;
