Concrete slab test piece coring device

Abstract

The invention discloses a large concrete slab test piece core taking device. A concrete core drilling machine is arranged on one side of a base. A longitudinal movable station and a transverse movable station perpendicular to the longitudinal movable station are arranged above the base. A test piece fixing water collection and drainage groove is formed in the transverse movable station. A cover plate with a hole is arranged on the test piece fixing water collection and drainage groove. The body of the longitudinal and transverse movable stations is a four-side frame. One opposite sides of the four-side frame are drill rods. The two drill rods are sleeved with bit shank sleeves. The bit shank sleeves are fixed through a connecting transverse plate. A nut is arranged in the middle of the connecting transverse plate. A lead screw fixing sleeve is arranged in the middle of the other side, connected with the drill rods, of the four-side frame. A lead screw passes through the portion between the nut and the lead screw fixing sleeve. A handle wheel is fixedly arranged at one end of the lead screw. The large concrete slab test piece core taking device is low in cost, high in production efficiency, good in core taking effect, easy to operate, high in practicability, safe and environmentally friendly.

Description

technical field [0001] The invention relates to the field of processing concrete large slab test pieces, in particular to a coring device for large concrete slab test pieces. Background technique [0002] With the continuous development of concrete technology in our country, shotcrete technology has been widely used in underground concrete support or anchor shotcrete support construction such as shafts, tunnels, culverts, and slopes. The workload of sprayed concrete test and detection has also been further increased. According to the market survey, at present, the professional manufacturers of concrete core drilling machines in the country do not produce supporting devices specially used for coring of large slabs of shotcrete indoors. [0003] Since there is no supporting device specially produced for indoor coring of large sprayed concrete slabs, the devices used by major scientific research institutes and testing and testing institutions for coring shotcrete large slabs a...

Problems solved by technology

Some are too bulky, and generally require 2-3 people in the process of coring each group of test pieces, which is a serious waste of manpower; some lack waste water and mortar collection devices, which is not conducive to environmental protection; some need to be manually pushed after taking out a core sample Drill the next piece of the large plate test piece, there is no special manual walking adjustment device
