Pile core sand drawing-out equipment used for buildings

Abstract

The invention discloses pile core sand drawing-out equipment used for buildings. The equipment comprises a support; an observation cavity of which the opening faces backwards is arranged in the support; a horizontal moving device is arranged in the observation cavity; and the horizontal moving device comprises a limiting block and a sliding cavity of which the opening faces downwards and rightwards, wherein the limiting block is glidingly connected with the inner wall of the front side of the observation cavity, and the sliding cavity is arranged in the limiting block. According to the equipment, a thread disk is employed to rotationally control the whole drawing-out equipment to move down, and the thread disk rotates through a grooved wheel mechanism, and thereby, multilayer uniform-descending clearing in height is further realized, and the condition that sand in a relatively deep hole is inconvenient to manually clear is avoided; moreover, sand in a pile core is drawn out by two hemispheric grabbing claws, so that the problem that sand flying can occur by a screw shaft drawing-out mode is avoided, and the environment and the body safety of a constructor are protected; and througha mechanical semi-automatic mode, only the sand needs to be manually pushed to change a discard position after the sand is removed, so that the work efficiency is accelerated.

Description

technical field [0001] The invention relates to the technical field of pile core cleaning, in particular to equipment for removing pile core sand for construction. Background technique [0002] In the field of building foundation construction, the application of high-strength prestressed concrete pipe piles is very common. In order to enhance the connection effect between pipe piles and caps, pipe pile cores must be reinforced concrete with a height of 2m to 4m. But in the pile sinking process, soil can be squeezed into the pile core, and the soil in the pile core must be pulled out before pouring reinforced concrete. Generally use manual shoveling, the efficiency is very low, and it is difficult to dig out the soil in a deep situation. The spiral type in the existing public technology removes the sand in the pile core. Due to the high-speed rotation of the central axis, the sand will move around due to centrifugal force. Flying, causing air pollution. The present inventio...
