Abstract
The invention provides an impact groove expander. Clamped sludge between an odd-sequence number groove section and an even-sequence number groove section can be removed by the impact groove expander. The impact groove expander comprises two parts, namely, a groove former and two groove expanders, wherein the groove former comprises a lifting ring at the upper end, a water-inlet rubber pipe, and a plurality of cutter teeth at the lower end; a water-inlet steel pipe is connected with the lower end of the water-inlet rubber pipe; a cross pipe is connected with the lower end of the water-inlet steel pipe; a plurality of water nozzles are formed on the lower part of the cross pipe; a side water nozzle is formed at each of two ends of the cross pipe; the groove expanders are respectively arranged on the two sides of a power head; a cutter head is arranged at the lower end of a cutter arm; the middle of the cutter arm is hinged to the power head through a hinging shaft B; the upper end of the cutter arm is hinged to the upper end of a top rod through a hinging shaft A; the lower end of the top rod can slide on the upper surface of the power head; the upper surface of the power head is provided with a groove and a convex ridge; the upper end of a tension spring is connected to the upper end of the cutter arm; and the lower end of the tension spring is connected to the upper surface of the power head.
Description
One, technical field
The present invention relates to a kind of slot expansion device, the impact slot expansion device that particularly a kind of underground continuous wall groove segment joint is used.
Two, background technology:
At present, impact grooving machine is built diaphragm wall and is all adopted segmentation to jump play construction, i.e. grooving list sequence number groove section first, by the time the concrete of single sequence number groove section reaches some strength, two sequence number groove sections between every two the adjacent single sequence number groove sections of grooving again, single sequence number groove section concrete connects to diaphragm wall with two sequence number groove section concretes.During the two sequence number groove section of grooving, for preventing bit freezing, the width of two sequence number groove sections should be greater than the width of groover unit head, so, in joint, just exist groover cutting less than place, always there is folder mud in single sequence number groove Duan Yushuan sequence number groove section joint, traditional impact grooving machine washes away folder mud by the water spout of groover both sides, scouring effect is very undesirable, and folder mud is serious.
Three, summary of the invention:
The present invention has made up the shortcoming of above groover, and a kind of impact slot expansion device that can fall clearly the folder mud between single sequence number groove Duan Yushuan sequence number groove section is provided.
The present invention is achieved through the following technical solutions:
A kind of impact slot expansion device, comprise capstan engine and slot expansion device two parts, capstan engine comprises the suspension ring of upper end, water inlet sebific duct, a plurality of cutters tooth of lower end, water inlet sebific duct lower end is connected with into water steel pipe, and water inlet steel pipe lower end is connected with transverse tube, transverse tube bottom is provided with a plurality of water spouts, and transverse tube two ends are respectively equipped with a side spray water nozzle; Slot expansion device has two, be located at respectively unit head both sides, tool arm lower end is provided with cutter head, centre is articulated with unit head by hinge B, upper end is articulated with the upper end of push rod by hinge A, the lower end of push rod can slippage on unit head upper surface, and unit head upper surface is provided with groove and protruding bank, extension spring upper end is connected in tool arm upper end, and extension spring lower end is connected in unit head upper surface.
The present invention has following feature:
When slot expansion device becomes two sequence number groove section, open, due to the effect of slot expansion device upper end extension spring, the cutter head of slot expansion device lower end is near the fist stage concrete joint face of single sequence number groove section, along with the cutter head of ballistic motion up and down of unit head is removed the folder mud of groove section joint.
Four, accompanying drawing explanation:
Below in conjunction with accompanying drawing, the present invention is further illustrated:
Accompanying drawing is structural representation of the present invention.
In figure: 1, suspension ring, 2, water inlet sebific duct, 3, water inlet steel pipe, 4, extension spring, 5, tool arm, 6, push rod, 7, hinge A, 8, cutter head, 9, hinge B, 10, side spray water nozzle, 11, transverse tube, 12, water spout, 13, cutter tooth, 14, groove, 15, first phase concrete joint, 16, unit head, 17, protruding bank.
Five, the specific embodiment:
Accompanying drawing is a kind of specific embodiment of the present invention, this embodiment comprises capstan engine and slot expansion device two parts, capstan engine comprises the suspension ring 1 of upper end, water inlet sebific duct 2, a plurality of cutters tooth 13 of lower end, water inlet sebific duct lower end is connected with into water steel pipe 3, and water inlet steel pipe lower end is connected with transverse tube 11, transverse tube bottom is provided with a plurality of water spouts 12, and transverse tube two ends are respectively equipped with a side spray water nozzle 10; Slot expansion device has two, be located at respectively unit head 16 both sides, tool arm 5 lower ends are provided with cutter head 8, centre is articulated with unit head 16 by hinge B9, upper end is articulated with the upper end of push rod 6 by hinge A7, the lower end of push rod can slippage on unit head upper surface, and unit head upper surface is provided with groove 14 and protruding bank 17, extension spring 4 upper ends are connected in tool arm 5 upper ends, and extension spring lower end is connected in unit head upper surface.
When the present invention becomes single sequence number groove section, the lower end of push rod 6 is withstood in groove 14, cutter head 8 just contracts and does not work in unit head.When the present invention becomes two sequence number groove section, push rod is pulled out to groove, due to the effect of extension spring, cutter head just ejects outside unit head, and cutter head is along with the folder mud of groove section joint is removed in the ballistic motion up and down of unit head.
