Abstract
The shield tail grease distributor belongs to the field of tunnel machinery, and includes cylinder, oil outlet connector, distribution plate, bearing sleeve, oil inlet, base seat, servo-actuator with driver and small gear. The oil inlet is fixed on the base seat by means of bolt, the bearing sleeve is connected with oil inlet by means of bolt, one end of the distribution plate is positioned with bearing sleeve by means of two bearings, and its another end is cover-mounted in the interior of oil outlet connector, said oil outlet connector is connected with cylinder by means of bolt, the servo-actuator with driver is fixed on the base seat, and connected with small gear so as to drive distribution plate and make it rotate.
Description
Technical field
The present invention relates to is a kind of distributor that injects seal grease, and particularly a kind of shield tail to rock tunnel(ling) machine seals the shield tail injected grease distributor that injects seal grease in the two road rings.Belong to the tunnel machine field.
Background technique
Complete-section tunnel boring machine one shield excavation machine has been widely used in city underground tunnel, municipal pipeline, railway and vcehicular tunnel, oil and gas pipeline engineering construction, mechanical, electrical, liquid integrated advanced person's engineering construction equipment.Shield tail sealing is contained in behind the shield after plating between the outer surface of section of jurisdiction, and purpose is to prevent that underground water and grouting behind shaft or drift lining material from infiltrating in the shield machine, has the effect of pressurize concerning earth pressure balanced shield, slurry-water balance type shield structure.The sealing of shield structure shield tail generally has three road metallic brush, forms two road rings between the three road metallic brush, injects seal grease in two road rings.When the shield structure advances, divide in the per pass ring at 4 and inject seal gease, two road rings have eight decanting points, because the height of position produce outlet pressure reduction difference, and shield tail grease pump has only an outlet, if adopt traditional endless tube to distribute naturally, can produce the nonuniformity of the oiling of each point, thereby influence the oiling effect, influence the performance of shield tail sealing.Find by literature search: Japanese Patent No. is: JP11013392, name is called: " the shield tail sealing of shield structure ", this patent is installed the contractile bag shape of expansible object outward by a kind of metallic brush that is positioned at tail end and is sealed, when the shield structure advances, some fillers are such as air, and water and oil carry out pressure transmission to contractile bag shape thing in pipe body under the effect of transmission and switching equipment, bag shape thing has been also just along with having stretched, and plays one sealing in that metallic brush is external.The technology of this shield tail sealing, need to do a contractile storage body of expansible, because of working environment very severe herein, for improving reliability in the outside of three road metallic brush, so the manufactured materials that stores body itself is required very high, manufacturing, mounting hardness are big.
Summary of the invention
The objective of the invention is at disadvantages of background technology and defective, a kind of shield tail injected grease distributor is provided.Contain certain fiber composition, the characteristic that viscosity is very high according to tail seal grease of shield, aim at N oil outlet successively by a filler opening and inject grease, grease all is impartial to the pressure and the flow of each oiling point like this, pressure by regulating grease pump and flow and every oiling time are regulated the grease pressure and the flow of each oiling point, make it simple in structure, volume is little, and conveniently moving is convenient to make and install.
The present invention realizes according to following technological scheme: the present invention includes: the actuating motor of cylinder, delivery connection, distribution switchboard, bearing housing, filler opening, base, tape drive, small gear, filler opening is by being bolted on the base, bearing housing is connected with filler opening by bolt, one end of distribution switchboard is by two bearings and bearing housing location, the other end is enclosed within the delivery connection, delivery connection is connected with cylinder with bolt, the actuating motor of tape drive is fixed on the base equally, thereby is connected the drive disc in rotation with small gear.
When cylinder bounces back, delivery connection and distribution switchboard are thrown off, at this moment start actuating motor, drive disc in rotation to next pouring orifice by small gear, aim at that hydraulic fluid port of wanting oiling, cylinder stretches out delivery connection and distribution switchboard is closed up, and starts the grease pump oiling, repeat above-mentioned process, make N oiling point finish oiling successively.
Grease all is impartial to the pressure and the flow of each oiling point like this, and pressure that can be by regulating grease pump and flow and every oiling time regulate the grease pressure and the flow of each oiling point, thoroughly solved traditional for a long time endless tube distribute naturally each oiling point that produces owing to pressure reduction causes the difficult problem of the nonuniformity of oiling, thereby guaranteed the sealing of shield tail.All parts all are installed on the base, install, move all very convenient.
The present invention has substantive distinguishing features and remarkable progress, has the following advantages: owing to be that a filler opening is aimed at N oil outlet injection grease successively, grease all is impartial to the pressure and the flow of each oiling point like this; Pressure by regulating grease pump and flow and every oiling time are regulated the grease pressure and the flow of each oiling point, can not be subjected to the influence of shield excavation machine diameter, have very strong versatility, especially using effect is better on the large-diameter shield development machine; And simple in structure, volume is little, and conveniently moving is convenient to make and install, and can use repeatedly, is installed in as required on the back supporting vehicle frame of rock tunnel(ling) machine.

Embodiment
As shown in Figure 1, the present invention includes: the actuating motor 7 of cylinder 1, delivery connection 2, distribution switchboard 3, bearing housing 4, filler opening 5, base 6, tape drive, small gear 8, filler opening 5 is by being bolted on the base 6, bearing housing 4 is connected with filler opening 5 by bolt, 3 one ends of distribution switchboard are by two bearings and bearing housing 4 location, the other end is enclosed within the delivery connection 2, delivery connection 2 usefulness bolts are connected with cylinder 1, the actuating motor 7 of tape drive is fixed on the base 6 equally, rotates thereby be connected drive distribution switchboard 3 with small gear 8.
When cylinder 1 retraction, delivery connection 2 is thrown off with distribution switchboard 3, starts actuating motor 7, and small gear drives distribution switchboard 3 and rotates the 45 degree, aims at filler opening 5.Cylinder 1 further stretches out, and delivery connection 2 closes up with distribution switchboard 3.
