Description
Technical Field
[0001] The utility model belongs to the technical field of bridge pile foundations, and in particular relates to a bridge pile foundation drill clamping and lifting device. Background Art
[0002] The foundation pile is composed of a foundation pile and a cap connected to the top of the pile. If the pile body is completely buried in the soil and the bottom of the cap is in contact with the soil, it is called a low cap pile foundation. If the upper part of the pile body is exposed to the ground and the bottom of the cap is above the ground, it is called a high cap pile foundation. The building pile foundation is usually a low cap pile foundation, but the pile foundation is prone to getting stuck during the construction process. The pile wall collapses and buries the pile foundation hammer, making it impossible to pull it out. A structure is now proposed that is convenient for pulling it out from the collapsed foundation pile. Utility Model Content

[0005] Beneficial Effects
[0006] The utility model provides a bridge pile foundation drill clamping and lifting device, which has the following beneficial effects compared with the prior art:
[0007] When the shell is buried in the foundation pile, the relevant technicians start the motor, so that the motor drives the gear meshing with its output gear to rotate synchronously, so that the gear drives the screw fixed at its axis to rotate synchronously, so that the first slide cylinder threaded on the screw starts to move linearly, so that the first slide cylinder drives multiple connecting rods B hinged on it to start moving synchronously, and at the same time, the slide seat starts to move linearly along the slide rail at the connection between it and the push plate, so that the slide seat drives the connecting rod A hinged thereto to start moving synchronously, so that the connecting rod A and the connecting rod B cooperate with each other to start pushing the push plate hinged thereto, so that the push plate starts to push the surrounding of the shell. The second slide cylinder threaded on it starts to move linearly when the screw rotates, so that the second slide cylinder drives the top rod hinged on it to move synchronously, and the top rod starts to drive the pull rod hinged thereto, so that the pull rod starts to move in a circle with its hinge with the shell as a fulcrum, so that the pull rod drives the cone block fixed thereon, so that the cone block penetrates into the soil to reinforce the shell and prevent the shell from rotating when the push plate pushes the soil. When the soil is pushed open by the push plate, the pressure is reduced, and the screw can be controlled to flip to retract the cone block and the push plate, and at the same time, the shell is lifted using related devices.
