Description

Technical Field

[0001] The utility model relates to the technical field of building construction equipment, in particular to auxiliary equipment for removing pile foundation casings of deep and large bridges. Background Art

[0002] During the construction of bridge pile foundation, it is generally necessary to use casing to protect the bored piles. After the concrete pouring is completed and reaches a certain strength, the casing is removed to save steel. When removing the casing, auxiliary equipment is required to be fixed at the bottom of the casing to facilitate the convenient removal of the casing. Therefore, an auxiliary equipment for removing the casing of deep and large bridge pile foundations is proposed.

[0003] Among the existing technical solutions, a device for removing the pile foundation casing of a bridge is proposed, with publication number: CN216075113U, which relates to the technical field of building bridges. The device for removing the pile foundation casing of a bridge comprises a base, an adjustment component and a removal mechanism. The base is in two groups, and two groups of vertical plates are fixedly installed on the front sides of the two groups of bases. The adjacent side walls of the two groups of vertical plates are provided with tooth plates, and the outer walls of the tooth plates are fixedly installed with clamping plates, and the two groups of clamping plates form a clamping space.

[0004] In order to solve the existing removal method, a crane is usually used to pull and remove the pile foundation casing. However, the crane occupies a large area and has certain requirements on the place of use, which indirectly causes inconvenience in use. The prior art uses a clamping block, a connecting block and a moving block to quickly and conveniently clamp and fix the two sets of clamps to the pile foundation casing, laying the foundation for the next step of removal, and is suitable for clamping and fixing pile foundation casings of different sizes, which relatively improves the flexibility of the device. Through the coordinated use of connecting plates, gears and brake motors, the pile foundation casing can be driven to move upward to achieve the removal operation. However, the fixation of the auxiliary equipment connection is poor, which leads to the auxiliary equipment falling off easily when the casing is removed, thereby affecting the stable removal of the casing by the device.
