Abstract
The invention relates to piling machinery in construction engineering, in particular to an engineering percussion drill structurally comprising a chassis, a rack, a motor, a transmission mechanism, a front drum, a rear drum and a main drum which are driven by the transmission mechanism, a percussion assembly, a ridge spar and a percussion bit, wherein a steering plate is fixed on the ridge spar and hinged with the front end of the rack; the engineering percussion drill is characterized in that a left hoisting plate and a right hoisting plate are fixed on two sides of the ridge spar; a hinging front shaft pin is fixed in a hole corresponding to the rear end of the part where the hoisting plates protrude from the ridge spar; a shaft sleeve is fixed at the front end of the piston rod of a hydraulic cylinder; the shaft sleeve is sleeved on the excircle of the middle part of the front shaft pin in a way that the shaft sleeve is in moveable fit with the front shaft pin; a rear shaft pin for hinging, which is perpendicular to the piston, is arranged on the rear seat of the hydraulic cylinder; the rear shaft pin is sleeved in the seat hole of the hinging seat on the bottom beam of the rack in a way that the rear shaft pin is in moveable fit with the seat hole; the oil inlet/outlet port of the hydraulic cylinder is communicated with a control valve and a gear oil pump driven by the motor via pipes. The engineering percussion drill of the invention has the advantages that the vertical state and horizontal state of the ridge spar can be achieved by the hydraulic system, thus achieving the single-machine operation.
Description
Technical field:
The present invention relates to construction work piling machinery, particularly engineering impact drill.
Background technology:
The head-pulley that engineering impact drill is driven by underframe, frame, motor, transmission mechanism, transmission mechanism, back reel, main drum, impact assembly, day beam mast, drill hammer are formed, and are fixed with deflecting plate, deflecting plate on the sky beam mast by hinge joint pin and frame front end frame enforcement hinge joint.When complete machine moved, day beam mast rotated the flat plane on frame of crouching around the hinge joint pin, relied on crane lifting to become tiltedly upright shape during duty.Triple barrel divides the work telephone-moving respectively, hangs reinforcing cage, hangs and expect to manage, hang drill bit, the intermittent lift work that hits of weight.
Owing to flat for sleeping in, oblique the standing of a day beam mast needs lifting operation, can't the unit operation bring many unfavorable factors, and lifting operation is time-consuming many, there is hidden danger simultaneously again.
Summary of the invention:
The objective of the invention is to overcome above-mentioned defective, a kind of engineering impact drill is provided.
The solution of the present invention is: above the deflecting plate of beam mast both sides, sky respectively about secured in parallel two rectangles play boatswain chair, two rectangles play boatswain chair and protrude and fixes pivot pin before the hinge joint in the rearward end corresponding aperture of mast position; The piston rod front end of a hydraulic jack is fixed with axle sleeve, pivot pin middle part cylindrical before this axle sleeve is linked in movingly, the hydraulic jack back seat be provided with for hinge joint with and with piston back pivot pin in vertical state, this back pivot pin is enclosed within the hole that is fixed on the frame bottom girder hinge joint seat movingly; Hydraulic jack passes in and out oily port and implements to be communicated with the gear oil pump of by-pass valve control, driven by motor by pipeline.
The invention has the advantages that: this machine utilizes hydraulic system to realize that the upright of day beam mast crouches, thereby realizes the unit operation.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
The specific embodiment:
Structure of the present invention is by underframe (7), frame (6), motor, transmission mechanism, the head-pulley that transmission mechanism drives, back reel, main drum, impact assembly (4), it beam mast (1), drill hammer is formed, be fixed with deflecting plate (10) on it beam mast (1), deflecting plate (10) is implemented hinge joint by hinge joint pin and frame (6) front end frame, it is characterized in that: in sky beam mast (1) both sides deflecting plates (10) tops respectively about secured in parallel two rectangles play boatswain chair (2), two rectangles play boatswain chair (2) and protrude and fixes pivot pin (3) before the hinge joint in the rearward end corresponding aperture of mast (1) position; The piston rod front end of a hydraulic jack (9) is fixed with axle sleeve, this axle sleeve is linked in preceding pivot pin (3) middle part cylindrical movingly, hydraulic jack (9) back seat be provided with for hinge joint with and with piston back pivot pin (8) in vertical state, this back pivot pin (8) is enclosed within the hole that is fixed on frame (6) bottom girder hinge joint seat movingly; The oily port of hydraulic jack (9) turnover is implemented to be communicated with the gear oil pump of by-pass valve control, driven by motor by pipeline.
Because hydraulic jack (9) back seat is to go up the hinge joint seat with frame (6) to be the hinge joint state, and the piston rod front end also is the hinge joint state with a day beam mast (a 1) boatswain chair (2), when therefore piston rod is flexible, hydraulic jack (9) can rotate around back pivot pin (8), piston rod also can rotate around preceding pivot pin (3), therefore hydraulic jack (9) integral body can rotate and flexible compound motion, promoting day beam mast (1) rotates around frame (6) front end frame hinge joint pin, thereby realize flat crouching with tiltedly upright, simple to operation, realize the unit operation, simple and reasonable.
