Description

Technical Field

[0001] The utility model relates to the technical field of shield machines, in particular to an assembled grouting stopping system. Background Art

[0002] The full name of the shield machine is tunnel boring machine. It is a tunnel excavation equipment that uses the shield method. Its main working principle is to use a cylindrical steel component to advance forward along the axis of the tunnel while excavating the soil. During the excavation process, the shield not only excavates the soil, but also serves as a temporary support to protect the excavated tunnel section from the pressure of the surrounding soil and groundwater pressure. While the shield machine is excavating, it will build the lining of the tunnel, which is significantly different from the open construction method. When using shield construction underground in cities, a grouting stop device is essential to control surface subsidence and prevent the backflow of grouting at the shield tail.

[0003] The existing Chinese patent with announcement number CN203271747U discloses a shield tail sealing slurry stopping device, including a support frame, a slurry stopping plate, and a wire brush; the longitudinal section of the support frame is a rounded rectangle with one end open; the front end of the slurry stopping plate is placed on the outside of the support frame, and its rear end is located above the horizontal plane, with an angle of 10 to 90 degrees to the horizontal plane; the front end of the wire brush is placed inside the support frame, and its rear end is located below the horizontal plane, with an angle of 10 to 90 degrees to the horizontal direction; the front end of the wire brush is placed inside the support frame, and the rear end is retracted and suspended in the air; the front end of the slurry stopping plate is connected to the front end of the wire brush and the support frame through a connecting device.

[0004] Although the above scheme is not affected by the deformation of the shield tail and has high installation accuracy, the assembly of the slurry stop plate and the wire brush of the device is not firm enough. When they need to be fixed by welding, the positions of the two are easy to move during the welding process, thereby affecting the accuracy of the welding position. Therefore, it does not meet the existing needs. In this regard, we propose an assembled slurry stop system. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model has a transmission cavity formed on the lower side of the bottom plate, and a plurality of equally spaced slots formed on one side of the lower end of the slurry stop plate. When the slurry stop plate and the wire brush are inserted into the bottom plate for fixation, the card block will be inserted into the slot. The slot and the inclined surface of the slot are connected to facilitate the insertion operation. The elastic action of the first return spring will make the card block firmly inserted into the slot. When welding is performed, the card block will not fall out of the slot, thereby ensuring that the whole will not be displaced during welding and fixing, thereby ensuring the accuracy of welding.

[0017] 2. The utility model has three equidistantly distributed sliding grooves on one side of the lower end of the bottom plate.

Therefore, if the stop plate vibrates during use, the anti-slip block can slide synchronously inside the sliding groove through the sliding rod. The vibration amplitude of the stop plate can be slowed down by the elastic action of the second buffer spring. The friction force generated by the sliding of the anti-slip block can also consume the energy input by the vibration, thereby ensuring the stability of the stop plate during use.

[0018] 3. The utility model has a plurality of docking grooves distributed in a rectangular array at the lower end of the wire brush, and a plurality of docking protrusions distributed in a rectangular array are welded to the upper end of the slurry stop plate. Before the slurry stop plate and the wire brush are inserted into the bottom plate for fixation, the operator can first insert the docking protrusion into the docking groove, thereby ensuring that the slurry stop plate and the wire brush will not be offset after being fitted, thereby ensuring that the bottom plate can be inserted in one step without the need for further adjustment due to offset, thereby ensuring the smoothness of assembly and fixation, and having good practicality.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: an assembled slurry stopping system, comprising a bottom plate 1, a steel wire brush 2 is arranged on the upper side of the bottom plate 1, a slurry stopping plate 3 is arranged on the lower side of the steel wire brush 2, and the slurry stopping plate 3 is fitted with the steel wire brush 2, and one end of the steel wire brush 2 and the slurry stopping plate 3 both extend to the outside of the bottom plate 1;

[0026] It also includes a transmission cavity 6, which is opened on the lower side of the bottom plate 1, and a moving block 9 is arranged inside the transmission cavity 6. Three equally spaced card blocks 10 are welded to the upper end of the moving block 9, and one end of the card blocks 10 penetrates and extends to the outside of the transmission cavity 6, and the card blocks 10 are slidably matched with the transmission cavity 6;

[0027] It also includes a slide groove 13, which is opened on one side of the transmission cavity 6, and three slide grooves 13 are opened at equal intervals. A slide rod 14 is provided inside the slide groove 13, one end of the slide rod 14 extends to the outside of the slide groove 13, and the slide rod 14 is slidably matched with the slide groove 13. A connecting plate 15 is provided on one side of the base plate 1, and the connecting plate 15 is welded and fixed to one end of the slide rod 14 located outside the slide groove 13, and the connecting plate 15 is fixed to one end of the slurry stop plate 3 located outside the base plate 1 by bolts.

[0028] When in use, the base plate 1 is fixed to the tail shell of the shield machine, and the docking protrusion 5 of the wire brush 2 and the stop plate 3 is inserted into the docking groove 4 to achieve a firm fit and prevent displacement. When the stop plate 3 is inserted into the base plate 1, the first return spring 8 drives the card block 10 to automatically enter the card groove 11 to ensure a firm assembly. When disassembly is required, pull the pull plate 12 to compress the spring and release the card block 10. Before welding, bolts are used to fix the stop plate 3 and the connecting plate 15 to enhance stability. When the stop plate 3 vibrates, the slide rod 14 drives the anti-slip block 16 to slide in the slide groove 13 to consume vibration energy. The second return spring 17 provides buffering to protect the stop plate 3 and ensure its stable operation.

[0029] See also Figure 3 Guide rods 7 are welded at the four corners of the transmission cavity 6, and the guide rods 7 penetrate the moving block 9, and the guide rods 7 are slidably matched with the moving block 9. The setting of the guide rods 7 can ensure that the moving block 9 maintains a stable straight track when moving up and down, and prevents deviation or shaking, thereby improving the accuracy and reliability of the engagement between the card block 10 and the card slot 11;

[0030] See also Figure 3 The lower side of the outer portion of the guide rod 7 is sleeved with a first return spring 8, one end of the first return spring 8 is connected to the moving block 9, and the other end of the first return spring 8 is connected to the transmission chamber 6. The first return spring 8 can provide a continuous elastic force for the moving block 9, so that when there is no external force, the card block 10 can automatically snap into the card slot 11 to achieve a self-locking function, thereby enhancing the stability of the connection between the stop plate 3 and the bottom plate 1;

[0031] See also Figure 3 The upper end of the slurry-stopping plate 3 located at one end inside the bottom plate 1 is welded with a plurality of docking protrusions 5 distributed in a rectangular array, and the lower end of the wire brush 2 located at one end inside the bottom plate 1 is provided with a plurality of docking grooves 4 distributed in a rectangular array, and the docking grooves 4 are all adapted to the docking protrusions 5. The precise matching of the docking protrusions 5 and the docking grooves 4 can ensure that the wire brush 2 and the slurry-stopping plate 3 are quickly and accurately docked during installation, avoiding misalignment or gaps, and improving the overall sealing and stability;

[0032] See also Figure 3 The lower end of the stop plate 3 located at one end inside the bottom plate 1 is provided with a plurality of equally spaced card slots 11, and the card slots 11 are all matched with one end of the card block 10 located outside the transmission chamber 6. The cooperation between the card slots 11 and the card block 10 realizes the mechanical locking between the stop plate 3 and the bottom plate 1, and can maintain a stable connection state even under the action of external force, and is not easy to loosen or fall off, thereby ensuring the safety and stability of the shield machine during the excavation process;

[0033] See also Figure 4 , an anti-slip block 16 is slidably arranged inside the slide groove 13, and the anti-slip block 16 is welded and fixed to the slide rod 14, and the anti-slip block 16 and the slide groove 13 are connected by a second return spring 17. When the stop plate 3 is vibrated or impacted, the anti-slip block 16 can slide in the slide groove 13 and compress or stretch the second return spring 17, thereby absorbing and dispersing the vibration energy, reducing the direct impact and damage to the stop plate 3, and improving its service life and stability;

[0034] See also Figure 2 A hidden groove 18 is provided at the lower end of the bottom plate 1, and a pull plate 12 is adhered and fixed to the lower end of the moving block 9. One end of the pull plate 12 passes through the transmission cavity 6 and extends to the inside of the hidden groove 18, and the pull plate 12 slides with the transmission cavity 6 and the hidden groove 18. The hidden groove 18 provides a hidden and easy-to-operate space for the pull plate 12, so that the operator can control the up and down movement of the moving block 9 by pulling the pull plate 12 without disassembling the bottom plate 1, thereby realizing the separation or engagement of the card block 10 and the card slot 11, simplifying the disassembly and installation process and improving work efficiency.

[0035] Working principle: When in use, the base plate 1 can be connected to the tail shell of the shield machine by installing it on one side of the inside of the base plate 1. When assembling the wire brush 2 and the stop slurry plate 3, the operator can first fit the wire brush 2 and the stop slurry plate 3 against each other, so that the docking protrusion 5 is inserted into the inside of the docking groove 4, which can avoid relative displacement between the wire brush 2 and the stop slurry plate 3, so that the wire brush 2 and the stop slurry plate 3 can be smoothly inserted into the inside of the base plate 1, ensuring the smoothness of assembly and fixation. When the stop slurry plate 3 is inserted into the inside of the base plate 1, the block 10 will continuously be inserted into the inside of the slot 11 through the elastic action of the first return spring 8. The inclined design of the block 10 and the slot 11 ensures the smooth movement of the stop slurry plate 3. Once the stop slurry plate 3 is inserted into the inside of the base plate 1, the elastic action of the first return spring 8 can prevent the block 10 from escaping from the inside of the slot 11, thereby 2 When welding, the displacement of the two can be avoided, and the accuracy of assembly is further guaranteed. When dismantling, the operator can pull the pull plate 12, and the pull plate 12 will move the moving block 9 downward, so that the first return spring 8 can be compressed, so that the card block 10 can be led out of the inside of the card slot 11, which is convenient for removal. Before welding, the operator can fix the stop plate 3 and the connecting plate 15 with bolts. When the stop plate 3 vibrates during normal use, the anti-slip block 16 can be made to slide synchronously in the inside of the slide slot 13 through the slide rod 14. The friction force generated by the sliding can consume the vibration input energy. At the same time, the sliding of the anti-slip block 16 will stretch and squeeze the second return spring 17. The elastic recovery effect of the second return spring 17 can achieve buffering of the anti-slip block 16, and then the buffering protection of the stop plate 3 can be achieved, ensuring the stability of the stop plate 3 during use.
