The device can realize automatic scabbling, but still has certain not enough:

(1) because the widths of different prefabricated hollow plate beams are not necessarily the same, even the widths of different positions of the same plate beam are possible to change, the widths of the two sides of the gantry of the equipment are fixed, the width change of the plate beam is not easy to adapt to, although the length of the burr head can be adjusted by arranging the screw and the spring, the structure and the operation of the equipment are complex, the adjustment degree is limited, and the universality of the equipment is poor;

(2) the side web of precast slab roof beam often has removal inclination, and the portal of the installation chisel hair head of above-mentioned equipment is perpendicular with the horizontal plane, consequently can only establish one row of chisel hair head to set up elevating system adjustment chisel hair head and reciprocate and chisel hair to the not co-altitude department of web of beam, efficiency is lower.

Disclosure of Invention

The utility model aims to provide a not enough to current chisel hair equipment existence improves its structure, provides an adaptable different beam slab width and web inclination's full-automatic chisel hair machine, improve equipment's suitability and efficiency of construction.

The technical scheme of the utility model as follows:

the utility model provides an automatic bush hammer of prefabricated hollow slab roof beam, includes a frame, the frame is equipped with the frame, and the frame bottom is equipped with the walking wheel, is equipped with walking wheel actuating system on the frame, its characterized in that: the frame is also provided with a hydraulic control system and a gear motor, two sides of the frame are respectively provided with a horizontally arranged cross beam, the two cross beams respectively transversely penetrate through the frame from two sides of the frame, the two cross beams are arranged in the middle of the frame in an up-down opposite manner, the up-down opposite surfaces of the two cross beams are provided with clamping teeth, a gear is arranged between the up-down opposite surfaces of the cross beams and is simultaneously meshed with the clamping teeth on the two cross beams, and the gear is driven by the gear motor; one end of each cross beam extends to a certain length outside the frame and is rotatably connected with a vertically arranged scabbling arm through a rotating shaft, a scabbling head is arranged on one side, facing the frame, of the scabbling arm, the upper end of the scabbling arm protrudes above the top surface of the cross beam by a certain height, a hydraulic oil cylinder is arranged between the upper end of the scabbling arm and the cross beam, the two ends of the hydraulic oil cylinder are respectively connected with the upper end of the scabbling arm and the cross beam through the rotating shaft, and the hydraulic oil cylinder is driven by a hydraulic control system.

The utility model discloses a flexible adjustment chisel hair arm of crossbeam and the different width of prefabricated plate beam web's distance in order to adapt to the slab beam, push away chisel hair arm upper end through hydraulic cylinder, the inclination of adjustment chisel hair arm is in order to adapt to the inclination of prefabricated plate beam web, adjustable angle scope 10, the regulative mode is nimble, the suitability is strong, establish multirow chisel hair head on the chisel hair arm, the chisel hair height can reach more than 50cm, can once accomplish the chisel hair of the whole side web of slab beam, can improve chisel hair efficiency and chisel hair effect by a wide margin.
