Description

Technical Field

[0001] The utility model relates to the technical field of shield machine cutter installation, in particular to an installation and fixing device for shield machine cutters. Background Art

[0002] With the acceleration of urbanization, the utilization of underground space has become increasingly important. In the construction of subways, tunnels, water conservancy projects and various infrastructures, the importance of shield machines as a key underground construction equipment has become increasingly prominent. The full name of shield machines is shield tunnel boring machines. With their high efficiency, precision, safety and environmental protection, they provide strong support for the construction of underground projects. As an important equipment for modern tunnel construction, the installation and maintenance of shield machine cutters directly affect the construction efficiency and project quality. The cutter installation device of the shield machine mainly consists of a cutter body, screws and reserved installation holes. When the cutter needs to be installed, just place the cutter in the predetermined installation position, and then tighten the screws to make it pass through the installation hole to firmly fix the cutter. However, the traditional bolt installation method is more cumbersome during operation, and the rust and damage of the bolts will make it more inconvenient to disassemble and replace them later, so there are certain disadvantages.

[0003] In summary, the utility model solves the existing problems by designing an installation and fixing device for a shield machine cutter. Utility Model Content

The term "and / or" used in this article includes any and all combinations of one or more related listed items.

[0025] For examples, see Figure 1-5 , the utility model provides a technical solution:

[0026] A mounting and fixing device for a shield machine tool comprises a support plate 1, a servo motor 2 is embeddedly mounted at the center of the outer side surface of the support plate 1, a rotating rod 3 is mounted on the output shaft of the servo motor 2, connecting rods 4 are mounted at both ends of the rotating rod 3, T-slots 101 are symmetrically opened on the outer side surface of the support plate 1 and at both ends of the servo motor 2, a T-slot 5 is mounted inside the T-slot 101, and a limiting plate 6 is mounted outside the T-slot 5;

[0027] A fixing block 7 is installed at one end of the wider outer side of the limiting plate 6, a telescopic rod 8 is installed at one end of the outer ring surface of the fixing block 7, a return spring 9 is installed on the outer ring surface of the telescopic rod 8, a cross plate 10 is installed on the top of the telescopic rod 8, and a positioning rod 11 is installed at the bottom end of the cross plate 10 away from the telescopic rod 8. A limiting hole 701 is provided at one end of the fixing block 7, a limiting block 12 is installed inside the limiting hole 701, a mounting block 13 is installed at one end of the limiting block 12, a positioning hole 1301 is provided on the outer ring surface of the mounting block 13, and a mounting groove 1302 is provided at the end of the mounting block 13 away from the limiting block 12, and a shield machine tool body 14 is installed between the outside of the mounting block 13 and inside the two mounting grooves 1302.

[0028] Specifically, refer to Figure 2 The two ends of the rotating rod 3 are rotationally connected to the two connecting rods 4 respectively, and the end of the connecting rod 4 away from the rotating rod 3 is rotationally connected to the outside of the limit plate 6 respectively, thereby ensuring that the rotating rod 3 is driven to rotate by the servo motor 2, and the rotation of the rotating rod 3 drives the two limit plates 6 to move relative to or away from each other through the two sets of connecting rods 4.

[0029] Furthermore, the outer dimensions of the T-slider 5 match the inner wall dimensions of the T-slot 101, and the outer portion of the T-slider 5 is slidably connected to the inner wall of the T-slot 101, thereby ensuring that the stability of the relative movement of the two limit plates 6 is increased by the T-slider 5 sliding inside the T-slot 101.

[0030] Furthermore, the inner wall size of the limiting hole 701 matches the outer size of the limiting block 12, and the inner wall of the limiting hole 701 is slidably connected to the outside of the limiting block 12, and the limiting block 12 is semi-cylindrical, thereby ensuring that the limiting blocks 12 on the mounting blocks 13 at both ends of the shield machine tool body 14 are respectively connected to the inside of the corresponding limiting holes 701, thereby fixing the shield machine tool body 14 between the two limiting plates 6.

[0031] Furthermore, a bearing is provided inside the installation groove 1302 , and the connecting shafts at both ends of the shield machine cutter body 14 are rotatably connected to the inside of the installation groove 1302 , thereby ensuring that the shield machine cutter body 14 can rotate to work.

[0032] For details, please refer to Figure 4 and Figure 5 The outer ring surface size of the positioning rod 11 matches the inner wall size of the positioning hole 1301, and the outer ring surface of the positioning rod 11 is slidably connected to the inner wall of the positioning hole 1301, thereby ensuring that when the two limit plates 6 move relative to each other, the cross plate 10 is pulled upward, and the cross plate 10 moves upward while driving the positioning rod 11 to move upward and stretching the telescopic rod 8 and the reset spring 9. When the two limit plates 6 move relative to each other and the two groups of limit blocks 12 are respectively connected to the corresponding limit holes 701, the cross plate 10 is released, and the restriction of the reset spring 9 is released, thereby driving the positioning rod 11 to connect to the inside of the positioning hole 1301, thereby ensuring the secondary fixed limit of the shield machine tool body 14.

[0033] The working process of the utility model is as follows: using a shield machine tool installation and fixing device designed by the present scheme, in the process of installing and fixing the shield machine tool, firstly, two sets of installation blocks 13 are installed at both ends of the shield machine tool body 14 to ensure that the shield machine tool body 14 can rotate to work, and then the shield machine tool body 14 is placed between the two limit plates 6, and the servo motor 2 drives the rotating rod 3 to rotate, and the rotation of the rotating rod 3 drives the two limit plates 6 to move relative to each other through the two sets of connecting rods 4, and the T-shaped slider 5 slides inside the T-shaped groove 101 to increase the stability of the relative movement of the two limit plates 6, and when the two limit plates 6 move relative to each other, the limit blocks 12 on the installation blocks 13 at both ends of the shield machine tool body 14 are respectively connected to the corresponding limit holes 701, thereby fixing the shield machine tool body 14 between the two limit plates 6, which is easy to install, and when the two limit plates 6 move relative to each other, pull the cross plate 10 upwards, and the cross plate 10 moves upwards while driving the positioning rod 11 to move upwards and stretching the telescopic rod 8 and the reset spring 9. When the two limit plates 6 move relative to each other and the two groups of limit blocks 12 are respectively connected to the corresponding limit holes 701, the cross plate 10 is released, and the restriction of the reset spring 9 is released, thereby driving the positioning rod 11 to connect to the inside of the positioning hole 1301, thereby playing a role in protecting the shield machine tool body 14 from secondary fixed limitation, and avoiding looseness between the limit block 12 and the limit hole 701 after a period of use, which causes the shield machine tool body 14 to shake during operation.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
