Description

Technical Field

[0001] The utility model belongs to the technical field of shield segment assembly auxiliary equipment, and more specifically, particularly relates to a jacking block for a shield machine. Background Technique

[0002] The shield method is a tunnel boring construction method. While the shield machine is boring, segments are quickly assembled into a ring. Generally, starting from the standard block (Type A) segment at the lower part, construction workers operate the robotic arm to alternately install the standard segments on the left and right sides in turn, then assemble the adjacent block (Type B) segments, and finally install the closure block (Type K) segment. Due to soil pressure or other reasons, the bolt holes of some closure block segments are misaligned with the bolt holes of the adjacent block segments on both ends. It is difficult to align the three by relying solely on the robotic arm, resulting in a step difference phenomenon, which affects the construction progress and the quality of the formed ring. Content of the Utility Model

[0003] In order to solve the above technical problems, the utility model provides a jacking block for a shield machine to solve the technical problem that in the prior art, when there is a step difference phenomenon during the assembly of the closure block segment, it is difficult to align the closure block segment and the adjacent block segment by relying solely on the robotic arm, which affects the quality of the formed ring.

[0004] The purpose and effect of a jacking block for a shield machine of the utility model are achieved by the following specific technical means:

[0005] A jacking block for a shield machine includes two groups of supports. Support blocks are arranged above the two groups of supports. Hydraulic rods are clamped between the two groups of support blocks and the two groups of supports. Connecting blocks are clamped on one side of the two groups of supports. Chutes are opened at both ends of the two groups of supports. A support beam is arranged below the two groups of supports. Multiple sliders are clamped on the top of the support beam, and the multiple sliders are respectively clamped in the multiple chutes. First installation grooves are opened on both sides of the support beam, and adjusting components are arranged in the two first installation grooves.

[0006] According to a preferred embodiment, the adjusting component includes two groups of threaded rods. One end of each of the two groups of threaded rods is clamped in the support beam, and motors are clamped at the other end of each of the two groups of threaded rods.

[0007] According to a preferred embodiment, fixing blocks are clamped at the bottoms of the two groups of supports, and the two groups of threaded rods respectively penetrate through the two fixing blocks.

[0008] According to a preferred embodiment, baffle plates are arranged on both sides of the support beam. Second installation grooves are opened on one side of the two baffle plates, and the two motors are respectively clamped in the two second installation grooves.

[0009] According to a preferred embodiment, multiple sets of connecting bolts are provided on both sides of the support beam, and one ends of the multiple sets of connecting bolts respectively pass through the two baffles and are clamped in the support beam.

[0010] According to a preferred embodiment, a capping segment is provided above the two support blocks, and two rubber plates are provided between the capping segment and the two support blocks, and the two rubber plates are respectively clamped on the tops of the two support blocks.

[0011] According to a preferred embodiment, adjacent segments are connected to both ends of the capping segment, and the two connecting blocks are respectively clamped on the inner sides of the two adjacent segments through multiple fixing bolts.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. When there is a step difference between the capping segment and the two adjacent segments, the device is installed between the two adjacent segments through multiple fixing bolts. The bolt installation is relatively simple and fast, which can improve work efficiency, reduce installation time and cost, and is more convenient for disassembly. By starting the hydraulic rod to apply pressure towards the capping segment, the capping segment can be pushed to the appropriate position, which can ensure the accuracy and precision of segment installation. At the same time, rubber plates are provided on the support blocks, which can increase the friction between the support plate and the capping segment to prevent accidental movement.

[0014] 2. The device drives the threaded rod to rotate through the motor, so that the two supports can slide, thereby adjusting the distance between them, enabling it to adapt to different segments. There is no need to redesign the support structure for each segment size, thus improving production efficiency and applicability. At the same time, the adjustment by the motor can simplify the operation steps and reduce manual errors. BRIEF DESCRIPTION OF THE DRAWINGS

The following embodiments are used to illustrate the technical solutions of the present utility model, but cannot be used to limit the protection scope of the present utility model.

[0022] Embodiment:

[0023] As Figures 1 to 3 shown, the present utility model provides a jacking block for a shield machine, which includes two groups of supports 1. Support blocks 6 are arranged above the two groups of supports 1. Hydraulic rods 4 are clamped between the two groups of support blocks 6 and the two groups of supports 1. By providing pressure through the two groups of hydraulic rods 4, the hydraulic system can achieve a large force output. The pressure applied by the hydraulic rods 4 can effectively push the segments and ensure the safety and reliability during the operation process. Connecting blocks 7 are clamped on one side of the two groups of supports 1. Slide grooves 16 are opened at both ends of the two groups of supports 1. A support beam 3 is arranged below the two groups of supports 1. Multiple slide blocks 15 are clamped on the top of the support beam 3. The multiple slide blocks 15 are respectively clamped in the multiple slide grooves 16. The slide groove design can provide guidance for the two groups of supports 1 and facilitate the installation of the two groups of supports 1 on the support 3.

[0024] Both sides of the support beam 3 are provided with first installation grooves 11. Threaded rods 10 are arranged in both groups of first installation grooves 11. One ends of the two groups of threaded rods 10 are clamped in the support beam 3, and motors 9 are clamped at the other ends of the two groups of threaded rods 10. Fixed blocks 12 are clamped at the bottoms of the two groups of supports 1, and the two groups of threaded rods 10 are respectively passed through the two groups of fixed blocks 12. The construction workers start the motors 9 to drive the threaded rods 10 to rotate, so that the two groups of supports 1 can slide, thereby adjusting the distance between them, enabling them to adapt to different segments, and there is no need to redesign the support structure for each segment size, which helps to improve production efficiency and applicability. At the same time, the adjustment by the motor can simplify the operation steps and reduce manual errors. Both sides of the support beam 3 are provided with baffles 2. The arrangement of the two groups of baffles 2 can limit the movement of the two groups of supports 1 and prevent them from sliding out of the support beam 3. At the same time, it is also convenient for the disassembly of the two groups of supports 1, which helps with subsequent maintenance work. Second installation grooves 13 are opened on one side of each of the two groups of baffles 2, and the two groups of motors 9 are respectively clamped in the two groups of second installation grooves 13. Multiple groups of connecting bolts 14 are arranged on both sides of the support beam 3. One ends of the multiple groups of connecting bolts 14 respectively pass through the two groups of baffles 2 and are clamped in the support beam 3. The two groups of baffles 2 can prevent the two groups of motors 9 from being exposed to the external environment, preventing soil, gravel or other substances from wearing the two groups of motors 9, thus ensuring the normal operation of the equipment and extending the service life of the equipment. Moreover, the installation and disassembly of the baffle 2 are relatively simple. Such a design helps with subsequent maintenance work on the motor 9 and improves the usability of the device.

[0025] As Figure 4 shown, a closure segment 18 is arranged above the two groups of support blocks 6. Two rubber plates 5 are arranged between the closure segment 18 and the two groups of support blocks 6. The two groups of rubber plates 5 are respectively clamped on the tops of the two groups of support blocks 6. Adjacent segments 17 are connected to both ends of the closure segment 18. The two groups of connectors 7 are respectively clamped on the inner sides of the two groups of adjacent segments 17 through multiple fixing bolts 8. When there is a misalignment between the closure segment 18 and the two groups of adjacent segments 17, it is difficult for the construction workers to align the three with only the robotic arm. Multiple hydraulic rods 4 can be started to push the closure segment 18 to a suitable position, thereby performing the assembly of the segments. The two groups of rubber plates 5 can increase the friction between the two groups of support blocks 6 and the closure segment 18, and can ensure that the two groups of support blocks 6 will not move accidentally when holding the closure segment 18, improving the safety during the construction process and ensuring the stability of the construction.

[0026] The specific usage and functions of this embodiment:

[0027] When the bolt holes of the closure segment 18 cannot be aligned with the bolt holes of the adjacent segments 17 at both ends due to earth pressure or other reasons, the construction workers can attach the two sets of connecting blocks 7 clamped on one side of the two sets of supports 1 to the inner sides of the two sets of adjacent segments 17 respectively, and then use multiple sets of fixing bolts 8 to complete the connection. When encountering different specified segments, the construction workers can start the two sets of motors 9 to drive the two sets of threaded rods 10 to rotate, thereby adjusting the distance between the two sets of supports 1. After the installation is completed, control the multiple sets of hydraulic rods 4 to jack the support blocks 6 upward, so as to jack the closure segment 18 to the designated area, align the bolt holes between the segments, and facilitate the segment installation work. A rubber plate 5 is clamped on the top of the support block 6, which can increase the friction between the support block 6 and the closure segment 18, and can ensure that the two support blocks 6 will not move accidentally when holding the closure segment 18.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments.
