Description

Technical Field

[0001] The present application relates to the technical field of shield machine segment connection, and in particular to a shield machine segment connection device. Background Art

[0002] The shield machine is a tunnel boring machine that uses the shield method. The shield machine segment is the main assembly component of the shield construction and is the innermost barrier of the tunnel. It is responsible for resisting soil pressure, groundwater pressure and some special loads. During the installation and construction of the shield machine segment, the segment connection structure needs to be used.

[0003] In the Chinese utility model patent with publication number CN213144479U, a shield machine segment connection device is provided. Personnel can insert the fixing block B on the top of the second segment into the connection groove at the bottom of the first segment, thereby inserting the plug-in plate into the fixing plate, and then insert the nut into the fixing block C to fix the segment A. Similarly, the third segment is fixedly connected with the fourth segment to fix the segment B, and then the segment A and the segment B are plugged into each other to form a segment connection, which facilitates installation by personnel and improves construction speed.

[0004] After searching and combining the experience in the actual construction process, it is found that the shield machine segment connection device proposed in the above technical solution still has the following defects and shortcomings: the connection stability and tightness between adjacent segments are poor, there is no more efficient locking function between adjacent segments, and during the segment installation process, the outer wall of the segment directly contacts and fits with the tunnel wall, but the above device installs bolts on the outer wall of the segment, so the actual construction operation is more complicated and inconvenient, affecting the construction efficiency. Therefore, it is urgent to improve the existing shield machine segment connection device and provide a shield machine segment connection device. Utility Model Content

The movable block 82 is threadedly sleeved on the outer side of the bolt 83. The bolt 83 is rotatably connected to the segment body 1 through a bearing.

[0009] The technical solution provided by this application may have the following beneficial effects:

[0010] When a plurality of segment bodies are used to form a ring body, the present application uses the arrangement of the clamping block and the first positioning groove to facilitate the clamping connection between two adjacent segment bodies, and when the segment bodies are laid along the tunnel, the vertical rod of another segment body can be inserted into the through hole opened inside the clamping block and can extend to the inside of the insertion hole, so that the vertical rod can be used to position the two adjacent left and right segment bodies, which can effectively enhance the stability and tightness of the segment connection;

[0026] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0027] See also Figure 1-4 The shield machine segment connection device includes a segment body 1, a first positioning groove 2 is provided at the top of the left end of the segment body 1, a socket 3 is provided at the center of the bottom end of the first positioning groove 2, a clamping block 4 matching the first positioning groove 2 is fixedly connected to the top of the right end of the segment body 1, a through hole 5 corresponding to the socket 3 is provided at the middle position of the clamping block 4, a plug-in groove 6 is provided at the top of the segment body 1, a locking component 8 is provided on the inner side of the plug-in groove 6, and a docking component 7 is fixedly provided at the bottom end of the segment body 1.

[0028] During operation, multiple segment bodies 1 are assembled and constructed in the tunnel to form a ring structure to support the tunnel hole. The setting of the clamping block 4 and the first positioning groove 2 facilitates the quick clamping connection between the two adjacent segment bodies 1 on the left and right. When the segment body 1 is laid along the tunnel, the socket 3 and the through hole 5 are positioned by the docking assembly 7 of the other segment body 1, so as to effectively improve the connection stability and tightness between the adjacent segment bodies 1 on the left and right. When the segment body 1 continues to be laid, the docking assembly 7 cooperates with the plug-in groove 6 for connection, and is locked by the locking assembly 8.

[0029] In some embodiments, the docking assembly 7 includes a vertical rod 71 and a mounting plate 72. The vertical rod 71 is fixedly arranged at the bottom of the left end of the pipe segment body 1. The center lines of the vertical rod 71 and the socket 3 coincide with each other. The length of the vertical rod 71 is equal to the sum of the lengths of the first positioning groove 2 and the socket 3. The mounting plate 72 is fixedly arranged at the bottom of the pipe segment body 1. A rectangular through groove 73 is opened inside the mounting plate 72. The mounting plate 72 and the plug-in groove 6 are located on the same vertical line, and the two are adapted to each other.

[0030] During operation, multiple segment bodies 1 are assembled and constructed in the tunnel to form a ring structure to support the tunnel hole. The setting of the clamping block 4 and the first positioning groove 2 facilitates the quick clamping connection between the two adjacent segment bodies 1 on the left and right. When the segment bodies 1 are laid along the tunnel, the vertical rod 71 of the other segment body 1 can be inserted into the through hole 5 opened inside the clamping block 4, and the end of the vertical rod 71 can extend to the inner side of the insertion hole 3, so that the vertical rod 71 can be used to position the two adjacent segment bodies 1 on the left and right. When the segment bodies 1 continue to be laid, the mounting plate 72 of the segment body 1 can be inserted into the inner side of the plug-in groove 6 opened inside the segment body 1 behind it, and the mounting plate 72 and the plug-in groove 6 are locked by the locking assembly 8 and the through groove 73.

[0031] In some embodiments, see Figure 5 The locking assembly 8 includes a slide groove 81, a movable block 82 and a bolt 83. The slide groove 81 is provided on the rear end inner wall of the plug-in groove 6. The inside of the slide groove 81 is slidably connected with the movable block 82. The movable block 82 is threadedly sleeved on the outside of the bolt 83. The bolt 83 is rotatably connected to the segment body 1 through a bearing.

[0032] During operation, the mounting plate 72 of the segment body 1 can be inserted into the inner side of the plug-in groove 6 opened inside the segment body 1 behind it, and then the bolt 83 can be controlled to rotate by using a tool to control the movable block 82 to slide stably in the direction of the plug-in groove 6 in the slide groove 81, and one end of the movable block 82 can be inserted into the through groove 73 opened inside the mounting plate 72, so that the front and rear adjacent segment bodies 1 can be locked, which is convenient for the stable laying construction of the segment, and the operating end of the bolt 83 is located on the inner side of the segment body 1. Compared with the comparative document, the present device is easier to operate.

[0033] In summary, during the process of connecting and installing the segment bodies 1, the present connecting device not only facilitates the quick snap-in connection between the segment bodies 1, but also can effectively position multiple adjacent segment bodies 1 on the left and right, front and back, thereby improving the connection stability between the multiple segment bodies 1, with higher construction quality, simpler structure, and more convenient operation.
