[0032] Example 2
[0033] The applicant's research found that:
[0034] The related pipe jacking machine shell crushing chamber device has the following problems during the construction process:
[0035] The existing pipe jacking machine crushing chamber is generally directly welded to the shell. After long-distance construction, the crushing chamber is generally severely worn, making the entire crushing chamber shell unable to be used a second time.
[0036] When the secondary crushing function is not required during pipe jacking construction, the entire first shell needs to be replaced, which results in poor component versatility and increased cost due to multiple configurations.
[0037] In view of this, if Figure 1 and Figure 2As shown, the present invention provides a replaceable shell crushing chamber device for a pipe jacking machine, comprising a first shell 1 connected to the second shell of the pipe jacking machine; a drive device 2 concentrically arranged at the front end of the second shell and connected to the cutterhead 3; and a crushing chamber 4 disposed within the first shell 1, which together with the cutterhead 3 constitutes a secondary crushing system. The crushing chamber 4 is disposed within the first shell 1 and employs a mounting and positioning structure to ensure concentric positioning with the first shell 1. Axial fixation is achieved by bolts passing through through-holes provided in the annular pressure plate 41 and bolt holes provided in the first shell 1 to achieve connection with the first shell 1.
[0038] In this embodiment, the positioning stop structure includes an outer ring stop 11 and an inner ring stop 12. The outer ring stop 11 is provided at the abutment between the front end of the first shell 1 and the annular pressure plate 41, and the inner ring stop 12 is provided at the abutment between the rear end of the first shell 1 and the rear end of the crushing chamber 4 (as shown in FIG. Figure 3 ).
[0039] In this embodiment, an annular block is provided at the front end of the first shell 1, and the distance between the inner and outer diameters of the annular block is greater than the distance between the inner and outer diameters of the front end of the first shell 1, and the center circumference of the annular block coincides with the center circumference of the front end of the first shell 1. Bolt holes are distributed around the center circumference of the annular block, and an outer ring stop 11 is provided at the front end of the annular block. The cross-section of the outer ring stop 11 and the annular block is a concave structure. The rear end of the first shell 1 extends toward its front end with a hollow cylindrical structure corresponding to the diameter of the rear end of the crushing chamber 4, and the front end of the hollow cylindrical structure is provided with an inner ring stop 12. The cross-section of the inner ring stop 12 and the hollow cylindrical structure is a convex structure. Specifically, the rear end of the annular pressure plate 41 and the rear end of the crushing chamber 4 are structurally arranged to correspond to the outer ring stop 11 and the inner ring stop 12 for engagement and positioning.
[0040] In this embodiment, when the pipe jacking machine does not need to use the secondary crushing function, the crushing chamber 4 is removed from the inside of the first shell 1, and the protective rings are respectively installed on the outer ring stop 11 and the inner ring stop 12 to prevent the positioning stop of the first shell 1 from being damaged during construction.

A second crushing bar 4 is axially provided on the inner wall of the crushing chamber 4. The torsion legs 31 rotate and the crushing chamber 4 is stationary. The relative rotational motion of the two together constitutes a secondary crushing system. The first crushing bar on the torsion leg 31 and the second crushing bar 42 provided on the crushing chamber 4 shear and squeeze the rock. The torque on the first shell 1 generated by the secondary crushing is borne by the bolts 5 connecting the first shell 1 and the annular pressure plate.
[0043] In this embodiment, the first shell 1 and the second shell are connected by bolts.
[0044] In this embodiment, the cutter head 3 is connected to the driving device via bolts.
