Embodiment 1

[0036] refer to Figure 1-3And 5-7, a self-locking blocking shield TBM construction auxiliary equipment, including a propulsion trolley 1, driving wheels are installed at the four corners of the bottom surface of the propulsion trolley 1, and a jacking assembly 2 is installed on the front side of the propulsion trolley 1, A drum 3 is fixed at the output end of the jacking assembly 2, and an auxiliary assembly 4 for assisting the assembly of segments is installed in the drum 3. During use, the installation position can be adjusted through the jacking assembly 2, so that the device can adapt to shields of different heights. Tunnel construction requires that after adjustment, the segments are assembled and spliced ​​sequentially through the auxiliary component 4, which is easy to operate, greatly improves the efficiency of shield splicing, and also ensures the quality of segment splicing. The auxiliary component 4 includes a rotating cylinder 41, which rotates The cylinder 41 is ...

Embodiment 2

[0038] like Figure 5-7 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the limit component includes a limit post 49, the outer wall of the limit post 49 is fixed with a limit rod 410, and one end of the limit rod 410 extends to the inner side of the threaded cylinder 1 45, The first end of the threaded cylinder 45 and the threaded rod 1 47 are provided with limiting grooves. The limiting grooves are slidably connected with a rotation blocking rod 411. The blocking rods 411 are fixed at both ends with a limiting piece 412, and a limiting column 49 is fixed on the rotating cylinder. 41 is on the side wall of one end, and the number of limit rods 410 is the same as that of threaded barrel 1 45, the limit groove is arranged in a cylindrical shape, the inner wall of the limit groove is also provided with a strip groove, and the limit pieces 412 are placed in the strip groove. so that the threaded cylinder 1 45 can be rotated while preventing the synchr...

Embodiment 3

[0041] like figure 2 and 4 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the jacking assembly 2 includes a second threaded barrel 21. The second threaded barrel 21 is provided with four threaded barrels and is rotatably mounted on the top surface of the propulsion trolley 1 in a rectangular shape. The inner walls of the second 21 are connected with threaded rods 22 through threads. The tops of the second threaded rods 22 are fixed on the bottom surface of the drum 3. A rubber cushion 23 is also fixed on the inner side of the middle of the bottom surface of the drum 3. There is a working frame 24 , the inner top surface of the working frame 24 is fixed with a second servo motor 25 , and the output end of the second servo motor 25 and the second threaded cylinder 21 are rotatably connected through a gear set.

[0042] In this embodiment, the second two threaded cylinders 21 are driven to rotate synchronously by the second servo motor 25 during us...

Abstract

The invention discloses self-locking blocking shield TBM construction auxiliary equipment which comprises a propelling trolley, driving wheels are installed at the four corners of the bottom face of the propelling trolley, a jacking assembly is installed on the front side of the propelling trolley, a roller is fixed to the output end of the jacking assembly, and an auxiliary assembly used for assisting in assembling duct pieces is installed in the roller. The auxiliary assembly comprises a rotating cylinder, the rotating cylinder is rotatably mounted on the inner wall of the roller, a gasket is fixed to the middle of the inner wall of the rotating cylinder, a first servo motor is fixed to the inner side of the gasket, a driving bevel gear is fixed to the output end of the first servo motor through a screw, and a first threaded cylinder is rotatably connected to the outer wall of one side of the rotating cylinder; the multiple first threaded cylinders are evenly distributed on the outer wall of one side of the rotating cylinder in a circle. The shield splicing device is reasonable in design, high in automation degree, convenient to splice the shield, low in working intensity and high in precision, and provides a certain guarantee for efficient and high-quality shield splicing.

Description

technical field [0001] The invention relates to the technical field of shield tunnel excavation auxiliary equipment, in particular to a self-locking blocking shield TBM construction auxiliary equipment. Background technique [0002] Shield tunnel technology has been widely used, but with the increasing development of cities, the demand for urban traffic is also increasing, and the construction standards of tunnels are getting higher and higher. The diameter of shield tunnels has increased from 6 to 11 meters. As large as the current 15 meters and above. The increase in diameter is a huge challenge to design and construction, which also increases the difficulty of installation during use. [0003] After searching, the patent with the application number 201910445896.7 discloses a shield tunnel segment, a shield tunnel segment assembling method and a shield tunnel segment assembling device. The method includes grabbing the segment to be assembled by a segment assembling machin...
