Description
Technical field
The utility model is applied to the afterbody muck removal gate of balancing earth-pressure shielding machine conveyor screw, this gate adopts eccentric structure, Wear during switch, and adopt the reversion cavity sealing structure, make conveyor screw have better leak tightness when closing, thereby actv. has prevented the ejection of muddy water.
Background technology
Domestic city subway construction fast development at present, balancing earth-pressure shielding machine is in great demand.Conveyor screw also has deslagging and buck functionality as the important component part of balancing earth-pressure shielding machine under the situation that keeps the excavation surface pressure.The muck removal gate of the conveyor screw of the shield machine that uses is commonly laterally straight door panel structure at present, leak tightness is not really desirable, earthing water and earth take place easily leak into shield machine in-to-in situation, and friction force causes the gate sheet serious wear more easily during the switch gate.
The utility model content
The purpose of this utility model provides a kind of gate structure of shield machine conveyor screw muck removal mouth, to improve the leak tightness of muck removal gate, prevents the wearing and tearing of gate sheet.
The technical solution adopted in the utility model is: the gate structure of shield machine conveyor screw muck removal mouth, comprise conveyor screw cylindrical shell, be located at the gate on the cylindrical shell muck removal mouth, the outer face of described cylindrical shell muck removal mouth adopts curved end, described gate comprises the arc door-plate that matches with the curved end of cylindrical shell muck removal mouth, and the arc door-plate is arranged on the cylindrical shell by eccentric rotating mechanism.
Described eccentric rotating mechanism comprise be hinged on the cylindrical shell both sides and with arc door-plate bonded assembly link, be contained in the hydraulic ram of cylindrical shell both sides, hydraulic ram and link are hinged.
The outer face of described cylindrical shell muck removal mouth is provided with sealing band.
Be provided with corresponding outer baffle outside the sealing band on the outer face of cylindrical shell muck removal mouth, on outer baffle, be provided with the seal grease joint.
The gate that the utility model will have shield machine conveyor screw muck removal mouth now changes the fan-shaped eccentric rotary gate of employing into, opens or closes gate thereby make the arc door-plate do arcuate movement by eccentric rotating mechanism.When gate was closed fully, the cylindrical shell outer face was concentric with the inside face of arc, and contact surface just coincide.Because what adopt is eccentric stiffener, the center of turn axis of its arc door-plate is above locating with one heart, and when gate was upwards opened, because accentric exists, the distance of arc door-plate and cylindrical shell outer face increased, and makes both have friction hardly.On cylindrical shell muck removal mouth outer face, sealing band is set, can strengthens the sealing property between arc door-plate and the muck removal mouth outer face.Outer baffle is set outside sealing band can forms a seal groove, when the arc door-plate cuts out, seal grease can be injected the sealing groove, make that the sealing effectiveness between arc door-plate and the muck removal mouth outer face is better by the seal grease joint.Because the arc door-plate when opening and closing, with the not friction of cylindrical shell outer face, therefore can be avoided the wearing and tearing to sealing band, guarantees that sealing band has long service life.

The specific embodiment
The gate structure of shield machine conveyor screw muck removal mouth of the present utility model as shown in Figure 1, comprise conveyor screw cylindrical shell 4, be located at the gate on the cylindrical shell muck removal mouth, cylindrical shell muck removal mouth is provided with a front and is the circular arc end face of rectangle, gate comprises the arc door-plate 3 that matches with the circular arc end face of cylindrical shell muck removal mouth, and arc door-plate 3 is arranged on the cylindrical shell 4 by eccentric rotating mechanism.
Eccentric rotating mechanism comprise be hinged on cylindrical shell 4 both sides and with arc door-plate 3 bonded assembly links, be contained in the hydraulic ram 1 of cylindrical shell both sides, hydraulic ram 1 is hinged with link.Link is made up of side plate 2 and rotor plate 5.Side plate 2 passes through bolted connection with arc door-plate 3, rotor plate 5 respectively.
The hydraulic actuating cylinder of arranging in cylindrical shell 4 bilateral symmetry 1 is installed on the bearing seat 6, and the junction is a revolute pair.Hydraulic actuating cylinder 1 is connected with the side plate of arranging in cylindrical shell 4 bilateral symmetry equally 2, and the junction also is a revolute pair.The boss of welding is connected on rotor plate 5 and the cylindrical shell 4, forms the 3rd group of revolute pair, the O ' point on its center of turn such as Fig. 2.Telescopic drive side plate 2, arc door-plate 3 by hydraulic actuating cylinder 1 rotate around the center of turn O ' point of rotor plate 5, realize the Push And Release of gate.Two horizontal sealing bands 7 among Fig. 3, two laggings 9 in cylindrical shell upper and lower end face by bolted connection on the cylindrical shell outer face, formed a back-shaped chamber jointly with two arc sealing bands 10 among Fig. 4, the curved baffle 11 that welds in the curved end left and right sides of cylindrical shell, wherein horizontal sealing band 7 and arc sealing band 10 constitute the inner ring in reversion chamber, and lagging 9 and curved baffle 11 constitute the outer ring in reversion chamber.The identical (see figure 1) of inside face radius of the outer face in reversion chamber and arc door-plate 3, they have a common center of circle when gate is closed fully, as the point of the O among Fig. 2, form the outer face and the arc inside face perfect fitting of back-shaped chamber parts this moment, on two cylindrical shell upper and lower end face laggings 9, two seal grease joints 8 are installed respectively, in back-shaped chamber, inject seal grease by seal grease joint 8, gate is sealed.
Adopt eccentric stiffener when design, as shown in Figure 1, oil cylinder is connected side plate 2 tops, and the center of turn during knife switch departs from and the homocentric some O of cylindrical shell central axis on same horizontal surface, is arranged in O point vertical direction one segment distance.Be the center of turn of side plate 2 as the point of the O ' among Fig. 2.Because the existence of eccentric stiffener, make fixing sealing band and baffle plate when shutter opening and closing with 3 generations of gates of segmental shape plate gap, the wear-out failure of avoiding between the two.
State when Fig. 5 upwards opens around its center of turn O ' point for gate, in Fig. 6, can know and see because accentric exists, the inside face of arc door-plate is no longer pasting the outer face of forming back-shaped chamber parts and is rotating, but along with the increase of gatage, the distance between outer face and the inside face also increases thereupon.This just makes and has friction between the two sides hardly, makes gate open and be more prone to.Eliminated simultaneously because the sealing band that direct friction causes between part and the wearing and tearing of baffle plate outside face.
When gate is closed, when arc inside face and sealing band and baffle plate outer face coincide, illustrate that gate just closes fully downwards.Because accentric exists, make the two sides press tighter and tighter if door-plate continues to be rotated down this moment, and door-plate can not be rotated further, so this gate mechanism also has auto-lock function.
The utility model is also included within the outer face of described cylindrical shell and does not establish sealing band or baffle plate, directly utilizes arc door-plate 3 to match with the circular arc end face of cylindrical shell muck removal mouth and realizes the leak free structure.
