Description

Technical Field

[0001] The utility model relates to the technical field of tunnel excavation construction, in particular to a quarrying box. Background Art

[0002] In a slurry shield, the slurry from the excavation face needs to be drained through pipes. Rocks in the pipes need to be filtered through a quarrying box to prevent them from blocking the slurry pump. Most quarrying boxes used in slurry shields consist of a box / tank + a grille. The grille aperture size is usually set according to the particle size that the slurry pump can pass through. Because the rock content and size of the strata within the same construction section vary, if the grille aperture is still set according to the conditions of large stone size under conditions with low rock content or size, the efficiency of the slurry pump will be affected, thereby slowing down the entire shield tunneling progress. Therefore, the grille aperture size needs to be adjusted according to the actual working conditions. In addition, the grille bars in the middle of the grille are prone to damage after long-term use and need to be replaced from time to time. Existing grilles are generally fixed in the box / tank. To change the grille aperture or replace the grille bars, the quarrying box needs to be disassembled and the operation performed, which is time-consuming and affects work efficiency.

[0003] In summary, there is an urgent need to provide a quarrying box to solve the problems existing in the prior art. Utility Model Content

[0033] See also Figure 1 and Figure 2 This embodiment provides a quarrying box, including a tank body 1, a tank body 2 and a grille 3, wherein the tank body 1 and the tank body 2 are connected; the grille 3 includes a grille ring 31, a pressure plate 32 and a plurality of grille bars 33, and the plurality of grille bars 33 are staggered on the grille ring 31 and fixed by the pressure plate 32; the grille ring 31 is arranged between the tank body 1 and the tank body 2, and the pressure plate 32 is detachably connected to the grille ring 31.

[0034] The quarrying box provided in this embodiment includes a tank body 1 and a tank body 2, a grille ring 31 is arranged between the tank body 1 and the tank body 2, and a pressure plate 32 fixes multiple grille bars 33 on the grille ring 31. The pressure plate 32 is detachably connected to the grille ring 31. When it is necessary to adjust the aperture of the grille 3 or replace the grille bars 33, there is no need to disassemble the quarrying box as a whole. It is only necessary to enter the tank body 1 and remove the pressure plate 32. The installation quantity or installation position of the grille bars 33 can be adjusted according to actual needs to achieve the aperture adjustment of the grille 3 or replace the damaged grille bars 33. The operation is convenient, time-saving and efficient.

[0035] In this embodiment, see Figure 1 The first end of the tank body 1 is provided with a slurry inlet 11, and the first end of the tank body 2 is provided with a slurry outlet 21; the second end of the tank body 1 and the second end of the tank body 2 are both provided with a connecting flange 4, and the two connecting flanges 4 are connected by bolts and nuts. The two connecting flanges 4 are connected, and the connection is provided with a groove, see Figure 2 and Figure 5 The grille ring 31 is provided with an annular boss 311 along the circumferential direction. The annular boss 311 matches the groove. The annular boss 311 is snapped into the groove to realize the installation of the grille ring 31.

[0036] The sidewall of the tank body 1 is provided with a gate 12, and the sidewall of the tank body 2 is provided with a pressure relief valve 22. Mud mixed with rocks enters the tank body 1 through the slurry inlet 11. After being blocked by the grille 3, the small rocks and mud enter the tank body 2 and are then discharged through the slurry outlet 21. When a certain amount of large rocks has accumulated in the tank body 1, the valves of the slurry inlet 11 and the slurry outlet 21 are closed, and the pressure relief valve 22 is opened to relieve the pressure in the tank body. After the pressure relief is completed, the gate 12 is opened, and the large rocks in the tank body 1 are removed through the gate 12.

[0037] In this embodiment, see Figure 2 and Figure 3 The grille ring 31 includes multiple grille ring blocks, and the pressure plate 32 includes multiple pressure plate blocks. Preferably, there are four grille ring blocks and four pressure plate blocks, and the grille ring blocks and pressure plate blocks are staggered. By configuring the grille ring 31 and pressure plate 32 as a block structure, the grille 3 can be installed and removed without disassembling tank body 1 and tank body 2 2. When the aperture of the grille 3 needs to be adjusted, the corresponding pressure plate block can be removed without removing the entire pressure plate 32. In addition, if the grille ring 31 or pressure plate 32 becomes damaged and needs to be replaced, only the corresponding block needs to be removed, without disassembling the quarrying box, which is convenient to operate and saves maintenance time.

[0038] In this embodiment, see Figure 2-Figure 5 The grille ring blocks are provided with threaded blind holes, and the pressure plate blocks are provided with countersunk threaded through holes. Bolts are sequentially inserted through the threaded through holes and the threaded blind holes to achieve a fastening connection between the grille ring 31 and the pressure plate 32. The grille ring blocks and the pressure plate blocks are staggered, so that the grille ring blocks and the pressure plate blocks are connected to form a stable whole.

[0039] In this embodiment, see Figure 3 The grille bars 33 include grille bars 1 331 and grille bars 2 332. The grille bars 1 331 and grille bars 2 332 are arranged in a staggered manner. In this embodiment, the grille bars 1 331 are arranged in a longitudinal direction, and the grille bars 2 332 are arranged in a transverse direction. Figure 6 and Figure 7 , bosses 333 are provided at both ends of the second grille bar 332 , and the height of the first grille bar 331 is the same as the height of the bosses 333 ; by providing the bosses 333 , it is convenient for the pressure plate 32 to press the second grille bar 332 .

[0042] In this embodiment, preferably, see Figure 3 The spacing between adjacent mounting grooves is not equal, so that the spacing between adjacent grille bars 33 is not equal. The staggered grille bars 33 can form holes with various apertures, expanding the range of aperture size that can be adjusted by the grille 3 according to actual usage, and improving the applicability of the grille 3.

[0043] When installing the grille 3, first clamp the four-part grille ring 31 into the groove formed by the two connecting flanges 4, and then install the grille bar 2 332 and the grille bar 1 331 in the installation groove of the grille ring 31 according to the actual working conditions (in this embodiment, see Figure 2 and Figure 4 After installing the grille bar 2 332 and the grille bar 1 331, the grille bar 1 331, the boss 333 and the grille ring 31 are coplanar with the side close to the pressure plate 32, which is convenient for pressing the pressure plate 32), then cover the pressure plate 32 and tighten the bolts to press the grille bar 33 between the pressure plate 32 and the grille ring 31.

[0044] When the aperture of the grille 3 needs to be changed or the grille bars 33 are damaged and need to be replaced, the valves of the slurry inlet 11 and the slurry outlet 21 of the quarrying box are closed, the pressure relief valve 22 of the quarrying box is opened to release the pressure, and the gate 12 is opened to clean the sand and gravel. At the same time, the staff can enter the quarrying box through the gate, remove the bolts and pressure plates 32 assembled on the grille 3, adjust the installation position or installation quantity of the grille bars 33 on the grille ring 31, or remove the damaged grille bars 33 and install new grille bars 33, then cover the pressure plate 32, tighten the bolts, and the grille aperture size can be adjusted or the grille bars 3 can be repaired and replaced.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
