Abstract
The utility model discloses a section-shaped multi-pass rotating joint for a shield tunneling machine. The joint comprises a rotating shaft and a plurality of section-shaped shells sleeved with the rotating shaft, the rotating shaft is internally and axially provided with mutually-independent axial channels with the number same as the section number of the section-shaped shells, each axial channel extends to the corresponding section-shaped shell from the left end, each section-shaped shell is internally provided with an entrance annular groove forming a cavity with the outer wall of the rotating shaft, each cavity is communicated to the corresponding axial channel by a radial channel and is communicated to the exterior of the corresponding section-shaped shell by a water inlet, and all the section-shaped shells are connected into a whole by a long bolt. The section-shaped multi-pass rotating joint for the shield tunneling machine has the beneficial effects that the structure of each section-shaped shell is simple, and the processing difficulty is lowered as the shells are divided into the plurality of very short sections for processing; the installation positions of external pipeline joints on the section-shaped shells are adjustable, so that interference among pipelines is reduced.
Description
Technical field
The utility model relates to the joint technique field, particularly a kind of shape of the joint for shield machine Multi-path rotary joint.
Background technique
Along with the quickening of domestic city subway process, shield machine becomes a kind of important engineering machinery of tunnel piercing.Shield machine fitting seat in construction is fixed, and cutterhead rotates, in construction, need continually to the knife cutting face, to add a large amount of media, such as: water, foam, bentonite clay, hydraulic oil, air etc.
And swivel joint is the connection seal arrangement that the conveyance conduit of flowing medium (foam, water, bentonite clay etc.) is connected with rotating equipment (cutterhead).It should guarantee successively to transmit fluid to rotating equipment, prevents again that flowing medium from ganging up mutually, leakage and external impurities enter working medium, thereby have influence on the normal work and use life-span of cutterhead.
A kind of swivel joint has been arranged in prior art, but complex structure, and manufacturing and installation are inconvenient, and related pipeline intersection is too many, is easy to mix up.
The model utility content
Goal of the invention of the present utility model is: for the problem of above-mentioned existence, provide a kind of novel shape of the joint for shield machine Multi-path rotary joint.
The technical solution adopted in the utility model is such: joint shape Multi-path rotary joint for a kind of shield machine, comprise turning axle and save the shape housings with some joints of its socket, in described turning axle, axially arrange identical with joint shape housing joint number, separate axial passage, each axial passage extends to corresponding joint shape housing from left end, offer the entrance circular groove in described joint shape housing, a cavity of the common formation of this entrance circular groove and turning axle outer wall, this cavity is communicated to corresponding axial passage by radial passage, be communicated to joint shape outside by water intake, each saves the shape housing and links into an integrated entity by a stay bolt.
As preferably, for further reinforcing respectively saves the connection between the shape housing, between described two adjacent segments shape housings, also with lag bolt, connect.
The wherein a kind of structure connected with lag bolt is as follows:
The lag bolt that connects two adjacent segments shape housings first runs through the lag bolt hole on a joint joint shape housing, then is threaded onto in the lag bolt blind hole on another joint joint shape housing.
As preferably, in order to prevent various flowing mediums, seepage occurs each other, be provided with Sealing between the common cavity formed of the described entrance circular groove that respectively saves the shape housing and turning axle outer wall.
The utility model right-hand member has been provided with the fork-shaped plate of fixation.
Described joint shape housing has six joints, and correspondingly, the axial passage in turning axle also has six.
In sum, owing to having adopted technique scheme, the beneficial effects of the utility model are:
1, joint shape shell construction is simple, is divided into very short some joints and processes, and has reduced difficulty of processing;
2, the mounting point of exterior line joint on joint shape housing is adjustable, has reduced the interference between each pipeline;
3, the Sealing between joint shape housing has obtained sharing, and effectively reduces cost.
The accompanying drawing explanation
Fig. 1 is main pseudosection of the present utility model.
Fig. 2 is the end view of joint shape housing in Fig. 1 embodiment.
Mark in figure: 1 is turning axle, and 2 is joint shape housing, and 3 is the fork-shaped plate, and 4 is Sealing, and 5 is stay bolt, and 11 is axial passage, and 12 is radial passage, and 21 is water intake, and 22 is the entrance circular groove, and 23 is the lag bolt hole, and 24 is the stay bolt hole, and 25 is the lag bolt blind hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Most preferred embodiment:
As shown in Figure 1, joint shape Multi-path rotary joint for a kind of shield machine, comprise turning axle 1 and save shape housings 2 with six joints of its socket, described turning axle 1 is interior axially arranges six separate axial passages 11, each axial passage 11 extends to corresponding joint shape housing 2 from left end, offer entrance circular groove 22 in described joint shape housing 2, a cavity of this entrance circular groove 22 and the common formation of turning axle 1 outer wall, this cavity is communicated to corresponding axial passage 11 by radial passage 12, be communicated to joint shape housing 2 outsides by water intake, each saves shape housing 2 and links into an integrated entity by a stay bolt 5.
For further reinforcing respectively saves the connection between shape housing 2, between described two adjacent segments shape housings 2, also with lag bolt, connect.
In the present embodiment, the wherein a kind of structure connected with lag bolt is as follows:
The lag bolt that connects two adjacent segments shape housings 2 first runs through the lag bolt hole 23 on a joint joint shape housing 2, then is threaded onto in the lag bolt blind hole 25 on another joint joint shape housing 2.As shown in Figure 2.
In order to prevent that various flowing mediums from seepage occurring each other, between the common cavity formed of the described entrance circular groove 22 that respectively saves shape housing 2 and turning axle 1 outer wall, be provided with Sealing 4.
The utility model right-hand member has been provided with the fork-shaped plate 3 of fixation.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
