Abstract

The utility model discloses a self-propelled sloping vertical grooving machine which can be used for preventing leakage for a levee. The utility model adopts an electric speed reducer to drive a rabble blade rod and a rabble blade through a slider-crank mechanism to do linear motion in a reciprocating way, and an adjustable speed motor is used for driving a crawler mechanism. The utility model is characterized in that the utility model adopts a one-way rabble blade, an adjustable hydraulic portal machine frame, and a sag preventing mechanism. The one-way rabble blade is welded on a hinge, and the one-way rabble blade can be rotated around a hinge shaft. Soil can be dug upwards, but not can be scraped downwards, and therefore, the resistance is reduced. The adjustable portal machine frame can be used for holding a cross beam horizontally by that the length of a retractable upright post is adjusted by a hydraulic oil cylinder, and therefore, the vertical grooving of a sloping surface is realized. When collapse, the sag preventing device can be adopted to automatically pull out a main beam and working parts to avoid huge economic losses.

Description

A kind of self-propelled hillside fields vertical channel machine

The utility model belongs to the vertical channel machine technology field in the water engineering machinery.

Vertical channel impervious wall technology is known as a kind of technical measures that effectively prevent dam leakage and piping by water conservancy circle.Song Hua River, China the Changjiang river in 1998 takes place after the catastrophic flood damage, in order to strengthen the dikes, domesticly developed various vertical channel machines one after another, by its workpiece and forms of motion can be divided into that chain harrow swinging, four bores that driving formula arranged side by side, rake teeth are reciprocating type, vibro-rammer tubular type etc.Wherein chain harrow swinging groove depth surpass 10 meters just easily by landslide bury, fluting speed is slow; Four bore driving formula groove depth arranged side by side, and can to reach 16～18 meters, fluting speed slower slightly than the former, and be difficult to guarantee that each groove is on same plane; The rake teeth reciprocating structure is simple, steel for engineering mechanism purpose iron amount is minimum, groove depth can reach 18 meters, but the rake teeth on the raking arm is the fixed effect that downward scraping is arranged, and this is a shortcoming; The stone amount is relatively more responsive to containing in the geology, structure is complicated for the vibro-rammer tubular type.In a word, various types come into operation, its function is each has something to recommend him, but has a common shortcoming: the first, and above-mentioned type all can not operation on embankment is domatic, if the embankment height is above 13～15 meters, above-mentioned type groove depth when the operation of embankment end face is just dark inadequately, must be in the place's operation of the domatic waterline of embankment, if it is smooth to require the scope of operation to carry out in advance, this is a regulation of violating the regulations of bank protection just to need to release the plane with bulldozer in advance, and it is exactly necessary at this moment adopting domatic vertical channel machine; If will need other bank protection in slope end operation, increase operating cost; If dike high 3～5 meters just needn't be and should be in the operation of levee crown face in domatic operation; The second, above-mentioned type substantially all is to belong to fixed, and assembled on site moves very difficultly, and this just influences the raising of operating efficiency; The 3rd, owing to groove depth, retaining wall are not good at causing easy landslide, the anti-subsidence of workpiece is resolved, and workpiece often occurs and is embedded in the incident of discarding in the soil and causing tremendous economic to lose

The purpose of this utility model is to provide a kind of self-propelled hillside fields vertical channel machine that unidirectional rake teeth, adjustable gantry stand and anti-sinking device are housed, and overcomes shortcoming that the downward scraping of existing fixed rake teeth increases resistance, gantry crossbeam level guarantees vertical channel and in case can be about to workpiece when caving in certainly and pull out and avoid loss when realizing the hillside fields operation.

To achieve these goals, the utility model is that a kind of self-propelled hillside fields vertical channel machine (Fig. 1) comprises electric reducer 1, slider-crank mechanism 2, the anti-mechanism 3 that falls into, central authorities' truss 4, hydraulic pressure is adjustable gantry stand 5, creeper undercarriage 6, rake teeth workpiece and girder 7, motor slush pump group 8, both sides truss 9, motor slush pump group 10, afer bay and walking mechanism 11, hoist engine 12, back shaft 13, electric reducer 1 and girder 6 are fixed together by base plate, and electric reducer 1 drives rake teeth bar and the rake teeth 7 that girders hang for 7 times by slider-crank mechanism 2 and carries out linear reciprocating motion; Back shaft 13 vertically passes girder 7 and welds together, and the bearing support of back shaft is fixed on the column of the adjustable gantry stand 5 of hydraulic pressure, makes the crossbeam keeping parallelism of back shaft and gantry stand, guarantees that also girder 7 is perpendicular to the ground horizontal plane; The wire rope of hoist engine 12 links to each other with the girder front aperture by fixed pulley, suspension hook, and hoist engine 12 can make girder and rake teeth workpiece 7 rotate up and down around back shaft 13, thereby realizes the control vertical channel degree of depth; Hydraulic pressure is adjustable, and gantry stand 5 is fixed on the creeper undercarriage 6, and buncher drives creeper undercarriage 6 and advances by central truss 4 both sides truss, 9 drive afer bays and walking mechanism; It is characterized in that: the rake teeth workpiece adopts unidirectional rake teeth 7, frame to adopt the anti-mechanism 3 that falls into that can pull out girder and workpiece after adjustable gantry stand 5 of hydraulic pressure and the landslide voluntarily.Unidirectional rake teeth 7 (Fig. 3) is made up of hinge 21, rake teeth 22 and angle iron 23, one end of hinge and angle iron all are welded on the rake teeth bar, the other end of hinge and rake teeth seam, rake teeth can rotate around hinge axis, rake teeth bar rake teeth when descending closes up, angle iron supports rake teeth work when up, its not scraping downwards of can only upwards cutting the earth; The hydraulically adjustable gantry stand (Fig. 3) that employing is made up of column 15, crossbeam 17, scalable column 19, hydraulic jack 20, two columns and crossbeam fixed connection, hydraulic cylinder piston rod and oil cylinder seat respectively with the core of scalable column and cover fixed connection, thereby can keep gantry crossbeam level to guarantee that rake teeth is at the vertical plane internal recessing in the hillside fields; The anti-mechanism (Fig. 4) that falls into is by slow-motion hoist 24, leading block 3, retainer ring 23, wire rope and girder front aperture are formed, two wire rope of two leading blocks of a slow-motion hoist that adopt central truss front end are along girder both sides axial distribution and meet in the girder front aperture, there is a disposable locating ring to keep the position of wire rope every two meters on the girder, in case slow-motion hoist is passed through in landslide, leading block twist wire rope is axially pulled out girder and workpiece along girder, all when moving locating ring to, locating ring is fixed on two screw M3 on the girder and can be broken and come off automatically not influence and pull out girder and workpiece.

Advantage of the present utility model is: the not scraping downwards of only upwards cutting the earth of unidirectional rake teeth reduces resistance; Adjustable gantry stand leave chain track (two parallel horizontal planes that 700mm is wide) in advance thus situation under can keep gantry crossbeam level vertical channel, this is the key that realizes domatic operation.When surpassing 12 meters, the embankment height can only be chosen in domatic operation.Owing to the proportion of slurry coat method not to or the drift sand geologic structure can adopt anti-sinking device to pull out girder when caving in and workpiece is avoided the tremendous economic loss.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
