Description

Technical Field

[0001] The utility model relates to the field of shield construction, in particular to a device for quickly turning over and discharging slag in a shield slag box. Background Art

[0002] With the continuous development of the national economy and science and technology, shield construction technology has gradually become more sophisticated and has gradually become the preferred technology for the construction of water conservancy tunnels. Compared with other construction technologies, shield construction methods have the characteristics of small site occupation, small impact on the outside world, high degree of automation, low labor intensity, and fast construction speed. Therefore, at this stage, it is widely used in the construction of tunnels in soft soil and soft rock. As the earth pressure balance shield machine advances forward, the soil on the face is cut off by the rotating cutterhead. After the soil enters the soil bin, it is transported to the dump truck's dump bucket by screw conveyors and belt conveyors. The soil is then transported from the tunnel to the surface dump site by battery locomotives in the tunnel and vertically by gantry cranes.

[0003] However, due to the site conditions and construction site limitations, a shield slag pool could not be set up in the working area of ​​the gantry crane. Therefore, a truck-mounted crane was installed on site to assist in slag dumping. When the crane is used to dump slag, the fully loaded bucket is lifted to the designated location in the slag yard and landed smoothly. The four lifting shackles on the top of the bucket are removed, and the shackles are then transferred to the turning ears at the bottom of the side. The hook is slowly lifted to pour the slag out of the bucket. After the dumping is completed, the bottom shackle is removed and installed on the four top ears, completing a working cycle. This traditional method of dumping slag requires frequent removal of the retaining ring, which consumes a lot of man-hours. Moreover, when the fully loaded bucket is turned over on the ground for dumping, the slag in the bucket cannot be completely dumped, and the lifting operation is risky. Therefore, the current slag dumping operation needs to be optimized and designed to improve construction efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0043] The present invention will be further described in detail below through examples. The examples are only used to illustrate the present invention and do not limit the scope of the present invention.

[0044] A device for quickly turning over and discharging slag in a shield slag box, comprising:

[0045] The enclosure 100 is a hollow rectangular parallelepiped structure, with its upper portion and front side both being open;

[0046] The support portion 200 is fixedly connected to the enclosure 100. There are two support portions 200 symmetrically arranged on both sides of the enclosure 100. The main body of the support portion 200 protrudes upward from the upper end surface of the enclosure 100.

[0047] The rotating portion 300 is located on the upper portion of the support portion 200 and is fixedly disposed between the two support portions 200. The hopper portion 400 is located on the upper portion of the enclosure 100 and is in contact with the rotating portion 300. The hopper portion 400 can be flipped relative to the rotating portion 300 so that the slag in the hopper portion 400 tilts downward. The enclosure 100 includes:

[0048] Side panel 110;

[0049] The second side panel 120 is located on one side of the first side panel 110 , and the first side panel 110 and the second side panel 120 are arranged in parallel;

[0050] The vertical panel 130 is vertically fixed to the rear ends of the side panel 110 and the side panel 2 120;

[0051] The bottom panel 140 is fixed to the bottom of the side panel 110, the side panel 2 120 and the vertical panel 130;

[0052] The main structure of the enclosure 100 is composed of a steel plate with a thickness of 20 mm. The side panel 110, the side panel 2 120, the vertical panel 130 and the bottom panel 140 form an enclosure area with a front opening, which is equivalent to forming a box structure with an open state; the front opening serves as an outlet for the slag in the hopper part 400 in the later stage. The enclosure area also provides a stable foundation for the hopper part 400 loaded with slag during the rotation process, thereby ensuring the stability of the overall structure during the rotation process. At the same time, the enclosure area enables the hopper part 400 to achieve a relatively smooth flipping process.

[0053] The support portion 200 includes:

[0054] The main support frame 210 is vertically fixed to the bottom panel 140 at its bottom, and is close to the side panel, which is the side panel 110 or the side panel 2 120. The main support frame 210 is made of 4500mm long HW300×300×10×15mm H-shaped steel. The main support frame 210 serves as the main load-bearing structure.

[0055] The outer support frame 220 is fixed vertically to the lower part of the outer side of the side panel. The outer support frame 220 is made of 2300mm long HW200×200×8×12mm H-shaped steel;

[0056] The outer support oblique frame 230 is tilted, with one end fixed to the top surface of the outer end of the outer support base frame 220, and the other end of the outer support oblique frame 230 is fixedly connected to the top of the main support frame 210; the outer support oblique frame 230 can be made of a rectangular plate or a No. 16 I-beam; the length of the outer support oblique frame 230 is 4600mm;

[0057] Preferably, a horizontal plate 231 is provided at the bottom of the outer support oblique frame 230, and the horizontal plate 231 extends inwardly, and a bolt hole 2311 is provided on the horizontal plate 231; Figure 3 The outer support base frame 220 is provided with a second bolt hole 221. The number of the second bolt holes 221 can be multiple and arranged side by side. The second bolt hole 221 is located at the outer side of the outer support base frame 220. The first bolt hole 2311 and the second bolt hole 221 are matched and arranged accordingly. The bottom of the outer support oblique frame 230 and the outer support base frame 220 can be connected by bolt fixation. Because the outer support base frame 220 is an H-shaped steel structure, it has notches 222 on both sides. When the bolt (not shown in the figure) passes through the first bolt hole 2311 and the second bolt hole 221 at the same time, the nut (not shown in the figure) is tightened on the bolt (not shown in the figure) from the notch 222 of the outer support base frame 220. The notch 222 is equivalent to providing an operating space, thereby more conveniently achieving the fixation of the cross plate 231 and the outer support base frame 220.

[0058] See Figure 4 、 5, a threaded column 2312 is fixedly provided on the top of the outer support oblique frame 230, and the number of the threaded column 2312 is two, and they are respectively located on both sides of the outer side of the outer support oblique frame 230, and the threaded column 2312 is a cylindrical structure, and the threaded column 2312 protrudes from the outer surface of the outer support oblique frame 230;

[0059] The outer side wall of the top of the main support frame 210 is provided with a third bolt hole 211. The number of the third bolt holes 211 can be multiple and arranged side by side. The threaded column 2312 matches and passes through the third bolt hole 211. The threaded column 2312 protrudes from the side surface of the main support frame 210. The outer support frame 230 is then fixed to the main support frame 210 by a nut 2313. The outer support frame 230 is designed to be detachable to facilitate later transportation and adjustment of the support position.

[0060] The rotating part 300 includes:

[0061] The rotating shaft 310 is a cylindrical structure, which is fixed between the two main support frames 210; the rotating shaft 310 is a solid steel column with a length of 2300mm and a diameter of DN100mm; the hopper part 400 can rotate around the rotating shaft 310, thereby realizing the dumping operation of the slag inside the hopper part 400, and the length of the center line of the rotating shaft 310 from the bottom end surface of the vertical panel 130 is 4400mm.

[0062] The rotary unit 300 further includes:

[0063] The limiting assembly 320 is fixed in the main support frame 210, one end of the rotary shaft 310 is fixed on the limiting assembly 320, and the rotary shaft 310 is fixedly connected to the main support frame 210 through the limiting assembly 320;

[0064] The limiting assembly 320 includes:

[0065] The outer limit sleeve 321 is in a "Π" shape and is disposed inside the main support frame 210; two bolt holes 3211 are provided on both the upper and lower sides of the outer limit sleeve 321;

[0066] The inner fixing block 322 is a rectangular parallelepiped structure, which is matched and fixedly arranged on the inner side of the outer limiting sleeve 321, and the bolt holes 3211 are located at the upper and lower parts of the inner fixing block 322;

[0067] Preferably, the middle position of the inner fixing block 322 is fixed with an embedded hole 3221, and the embedded hole 3221 is a circular hole. One end of the rotary shaft 310 is inserted into the embedded hole 3221, and the rotary shaft 310 is fixedly connected to the inner fixing block 322 through the embedded hole 3221.

[0068] The hopper section 400 includes:

[0069] The hopper box 410 is open at the top and has an inclined front side;

[0070] The slag turning lug 420 is fixed at the lower rear side of the slag bucket box 410. The slag turning lug 420 is in contact with the rotating shaft 310. Under the action of the slag turning lug 420, the slag bucket box 410 descends around the rotating shaft 310, thereby realizing the dumping operation of the slag inside the slag bucket box 410; by lifting the slag bucket box 410 to the rotating shaft 310, the slag bucket box 410 descends around the rotating shaft 310, thereby realizing the dumping operation of the slag inside the slag bucket box 410.

[0071] The traction rope 430 is fixed to the upper rear portion of the hopper box 410 and extends outward.

[0072] Preferably, upper lifting ears 411 are fixed on the upper part of the hopper box 410. There are four upper lifting ears 411 and they are symmetrically arranged on both sides of the hopper box 410. A hanging plate 412 is set on the upper part of the upper lifting ears 411. The upper lifting ears 411 are fixedly connected to the hanging plate 412 through a hanging rope 413. The hanging ropes 413 are distributed at the four corners of the hanging plate 412.

[0073] After the operator hoists the slag bucket part 400 into place, the operator aligns the slag turning lug 420 at the lower part of the slag bucket box 410 of the slag bucket part 400 with the rotating shaft 310. After the slag turning lug 420 and the rotating shaft 310 are aligned, the crane driver operates the crane hook head to descend, ensuring that the slag bucket box 410 always rotates and descends around the rotating shaft 310; as the slag bucket box 410 rotates, the slag inside the slag bucket 410 is completely dumped out under the action of gravity; then, the crane driver operates the hook to rise, thereby lifting the slag bucket box 410 away from the rotating shaft 310, thus completing a slag dumping process.

[0074] Installation: First, place the bottom panel 140 in place, and then weld the remaining side panel 110, side panel 2 120, vertical panel 130, and bottom panel 140 at corresponding positions to form a protective part 100. Then, hoist the main support frame 210 into the protective part 100. After the installation of the rotating part 300 is completed, finally install the external support diagonal frame 230. After fixed forming, it must be inspected and corrected. The interface should be firm and stable without any gaps.

[0075] Welding and correction (when welding is required): All welders must be certified; all fillet welds formed by splicing must be fully welded. After welding, the welder must conduct an appearance inspection and then correct local deformation.

[0076] Hoisting and installation: After the installation is completed, the bucket part 400 is hoisted to a stable place on the foundation of the slag field and placed in place. The bucket box 410 is filled with slag as a stable foundation to offset the overturning moment generated when the bucket part 400 is reversed.

[0077] In shield construction environments, cranes are generally used for auxiliary operations of soil dumping. The hoisting and dumping operation method is lagging behind, mainly including the following problems:

[0078] (1) The sling needs to be manually disassembled four times, which is time-consuming and labor-intensive;

[0079] (2) The force on the bucket is unstable during the dumping process, which poses a great safety risk.

[0080] (3) The shield construction efficiency is low, averaging 4 rings per day;

[0081] This device, used during the shield tunneling section construction of the first section of the Hanjiang, Rongjiang, and Lianjiang River water system connectivity and subsequent optimization project, shortened the time required for soil dumping, effectively resolving the time-consuming and inefficient process. The original method took 20 minutes to dump one bucket of soil, but this device reduced that time to 5 minutes, increasing average daily excavation efficiency to 6 to 8 tunneling rings. This accelerated the overall construction progress, reduced construction costs, and achieved significant economic benefits.
