Abstract
The invention relates to a spring groove expander for a groove sawing machine, comprising cutting boards, a spring and a fixing plate. Three cutting boards are respectively arranged at the upper part, the middle part and the lower part of the spring groove expander and fixed at the right end of the spring; the fixing plate is arranged at the left end of the spring and used for being connected with a sawblade support.
Description
One, technical field
The present invention relates to a kind of spring slot expansion device, particularly a kind of underground impervious wall The trench saw spring slot expansion device.
Two, background technology
The The trench saw operating principle is: submersible motor drives crank and rotates, and crank is by connecting rod, and two saw cuttves synchronously, moved back and forth the cuts formation grooving in opposite directions about rocking arm promoted.
The trench saw construction underground impervious wall generally adopts formula piecemeal, the construction of jumping play, I, III, V promptly at first construct ... the groove section, during Deng I, III, the certain intensity of V groove section concrete, II, IV, VI again construct ... the groove section, construction II, IV, the common way of VI groove section are to open the side direction water nozzle of the The trench saw saw cutter left and right sides, folder mud to groove section two ends in the grooving process washes away, go out 15 centimetres of capstan engines because II, IV, VI groove section be wide, being that capstan engine the right and left presss from both sides 7.5 meters in mud on one side, is unsatisfactory so only wash away by water nozzle.
Three, summary of the invention
The present invention provides a kind of The trench saw spring slot expansion device for remedying the deficiencies in the prior art.
The present invention is achieved through the following technical solutions:
A kind of The trench saw spring slot expansion device comprises knife plate, spring, fixed head.Knife plate is three of upper, middle and lowers, is fixed in the right-hand member of spring, and the left end of spring is provided with fixed head, is used for and saw being connected of knife rest.
Four, description of drawings
The invention will be further described below in conjunction with accompanying drawing
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is installation site figure of the present invention.
Among the figure: 1, knife plate, 2, spring, 3, fixed head, 4, fixed screw holes, 5, the saw knife rest, A, submersible motor, B, crank, C, rocking arm, D, saw knife rest
Five, the specific embodiment
Accompanying drawing 1 is a kind of specific embodiment of the present invention.This embodiment comprises knife plate 1, spring 2, fixed head 3.Knife plate is three of upper, middle and lowers, is fixed in the right-hand member of spring 2, and the left end of spring 2 is provided with fixed head 3, is used for and saw being connected of knife rest D.
The present invention is at construction II, IV, VI ... be fixed in the two ends, the left and right sides of two saw knife rests during the groove section, in the grooving process, remove the folder mud at groove section two ends along with the reciprocating motion of two saw cuttves.If meet I, III, V ... groove section concrete tilts or bulging, II, IV, VI ... the spring of spring slot expansion device also can normally tunnel, because can eject along with the width of groove section or bounce back.
