Embodiment 1

[0036] Embodiment 1: as Figure 1 to Figure 3 As shown, a self-propelled shield translation station passing system includes a base track 1, a shield base 13, a shield jack 8 arranged in the shield host 9, and a shield vehicle connected to the shield host 9 Rack 14. A frame platform 15 carrying a shield frame 14 is set up on the base rail 1, and the Bailey piece frame platform 15 is set up in a double-row single-layer manner. Five groups of running wheels 16 are respectively arranged under the longitudinal beams on both sides of the bottom of the shield base 13, and the running wheels 16 are connected to the bottom plate of the shield base 13 by bolts.

[0037] The base track 1 adopts 2 tracks of 50kg / m, which are welded on the base track steel plate 10 with a width of 35 cm and a thickness of 3 cm. The base track steel plate 10 is provided with threaded positioning pins 11 at intervals along the track direction. The positioning pin 11 has a diameter of 50 mm and a height of...

Embodiment 2

[0045] Embodiment 2: as Figure 7 As shown, the difference between this embodiment and Embodiment 1 is that the shield machine translational passing system also includes a track connecting plate 2, which is welded by thick steel plates and has a height of 200mm. The track connecting plate 2 is set on the side of the walking reaction force frame 4 away from the shield machine 9, and is fixedly connected to the base track 1 through the positioning pin 11 through the retaining nut 7, that is, there are 8 positioning pin holes at the bottom of the track connecting plate 2 , match the hole position of the positioning pin 11 on the base rail 1, and use the retaining nut 7 to tighten and fix it. A rear support 3 is fixedly connected between the track connecting plate 2 and the base of the inverted "T" shaped walking reaction force frame 4 by a pin shaft 12 .

[0046] Other structures of this embodiment are the same as those of Embodiment 1.

[0047] The working principle of this em...

Embodiment 3

[0048] Embodiment 3: as Figure 8 As shown, the structure of this embodiment is basically the same as that of Embodiment 2, the difference is: the flange on the first dowel 5 is connected with the second dowel 6, and the two are fixed with wedge pins so that the first dowel 5 The longitudinal positions of the rod 5 and the second dowel rod 6 are consistent with the axial direction of the shield jack 8 at the bottom of the shield machine 9, so no eccentric bending moment will be generated after the force is applied. The second dowel bar 6 is made by the thick-walled steel pipe of DN300 * 20.

[0049] In other specific implementations, on the premise of satisfying the performance, a third dowel can also be set on the second dowel 6 in the same way, and in the same way, so that the main shield machine can achieve greater progress. journey.

[0050] Other structures of this embodiment are the same as those of Embodiment 2.

[0051] This embodiment works as follows:

Abstract

The invention discloses a self-walking shield translation station-crossing system comprising a substrate rail, a shield substrate, a shield jack and a shield frame, wherein the shield jack is arranged in a shield host, the shield frame is connected with the shield host, and the substrate rail is lapped with a frame platform loading the shield frame. The self-walking shield translation station-crossing system is characterized in that the substrate rail is fixedly connected with a substrate rail steel plate; the substrate rail steel plate is provided with dowel pins with thread at interval along the rail direction; the substrate rail is fixedly connected with a walking counter-force rack by the dowel pins via retaining bolts; one side of the walking counter-force rack, which is opposite to the shield host, is fixedly connected with a first dowel steel corresponding to the shield jack; and the bottom of the shield substrate is provided with travelling wheels. The self-walking shield translation station-crossing system has high shield translation station-crossing speed, greatly lowers the amount of operating personnel, adopted equipment and the like and can accurately position the shield station-crossing axis and elevation.

Description

technical field [0001] The invention relates to a station-passing system for shield tunneling, which belongs to the field of tunnel construction. Background technique [0002] In the prior art, when the shield machine moves across the station, the power of the shield machine is cut off, the main frame of the shield machine and the supporting frame are disassembled, steel plates or multiple heavy rails are laid under the base of the shield machine, and the main machine of the shield machine is firmly connected to the base Finally, use a hoist or install a hydraulic jack to slide and translate the shield and the base on the steel plate or heavy rail to pass the station. After that, set up a platform for the vehicle frame to move over the station in translation. After the vehicle frame over the station platform is set up, use power equipment such as a hoist to move the vehicle frame platform over the station in translation. After passing the station, the main machine and frame...
