Compared with the prior art, the beneficial effects of the utility model are that:

the front shell is provided with the inner groove, the rear shell is provided with the lug, the lateral contact area is increased, the pipe jacking tunneling machine can perform bend operation, namely when the front shell and the rear shell need to be relatively deviated, the stress dispersion is ensured, and the service life of the shells is further ensured; meanwhile, the sealing ring pressed by the spring is arranged, so that the sealing effect of the sealing ring is better; the abutting plate is also provided with a corrugated bulge, so that the radial movement of the sealing ring is prevented.

Drawings

Fig. 1 is a schematic view of a partial structure of the present invention;

FIG. 2 is an enlarged view of portion A of FIG. 1;

in the figure: 10 front casing, 20 back casings, 30 fixing base, 31 jack, 40 inner grooves, 50 lugs, 60 sealing rings, 70 first limiting grooves, 80 second limiting grooves and 90 elastic pressing and abutting pieces.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, a pipe jacking heading machine shell body, this shell body includes procapsid 10 and back casing 20, the procapsid all is the cylinder with the back casing, the one end that procapsid, back casing are close to each other is provided with fixing base 30 respectively, two the fixing base articulates respectively in the both ends of jack 31, the jack is provided with a plurality ofly, lays along the radial direction ring of procapsid, back casing, and the jack is on a parallel with the axial direction of procapsid, back casing, the procapsid is provided with inner groovy 40 along its axial direction's cross-section, back casing is provided with lug 50 along its axial direction's cross-section, the lug is embedded in the inner groovy, be provided with sealing washer 60 between lug both sides and the inner groov. Specifically, a plurality of first limiting grooves 70 are uniformly formed in the two side walls of the inner groove, a plurality of second limiting grooves 80 are also uniformly formed in the two side surfaces of the protruding block, and the sealing ring is arranged in the first limiting groove and the second limiting groove which are matched with each other. The sealing rings are arranged on the inner side and the outer side of the convex block, so that excellent sealing is realized, and impurities such as soil are prevented from entering the shell.

Furthermore, an elastic pressing and abutting piece 90 is arranged on one side wall of the inner side of the first limiting groove, which is far away from the rear shell, and the elastic pressing and abutting piece abuts against the sealing ring.
