Technical Field

[0001] This invention relates to the field of shaft construction technology, and in particular, to a slag removal device and a shaft tunneling machine. Background Technology

[0002] As the diameter of the shaft increases, the fluidity of the rock debris at the bottom of the shaft will become increasingly poor. How to efficiently collect and discharge the rock debris from the bottom of the shaft is a current challenge in mechanized shaft construction. If the rock debris is not discharged in time, it will cause secondary wear on the excavation tools and affect the construction progress of the shaft.

[0003] Currently, large-diameter vertical shafts mostly use slurry pumps for slag removal. Due to the large excavation diameter, the rotation speed of the excavation equipment is limited, which cannot fully mix the rock debris at the bottom of the shaft, easily causing rock debris to accumulate and resulting in poor slag removal efficiency.

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Implementation Method 1

[0034] like Figure 1 and Figure 2 As shown, the present invention provides a slag discharge device, including at least one slag discharge mechanism 2, which is installed on an excavation device 1. The excavation device 1 can drive the slag discharge mechanism 2 to rotate in the circumferential direction C along the excavation surface 4. The slag discharge mechanism 2 includes a slag discharge structure 21 and a swing structure 22. The slag discharge structure 21 is connected to the excavation device 1 through the swing structure 22. The swing structure 22 can drive the slag discharge structure 21 to swing in the radial direction R of the excavation surface 4.

[0035] The slag removal device of the present invention is preferably installed on the excavation device 1 of a shaft boring machine, thereby realizing slag removal from the bottom of the shaft, and is particularly suitable for large-diameter shafts. Of course, it can also be installed on the excavation device of other underground engineering construction equipment.

[0036] The slag removal device of the present invention connects the slag removal structure 21 to the excavation device 1 via a swing structure 22. The swing structure 22 itself can drive the slag removal structure 21 to swing radially R on the excavation surface 4, and can also drive the slag removal structure 21 to rotate circumferentially C along the excavation surface 4 under the rotation of the excavation device 1. This combined circumferential rotation and radial swing allows the slag removal structure 21 to form a larger slag removal range, more fully transferring rock debris from the entire excavation surface 4; and / or can use the slag removal structure 21 to stir the rock debris on the excavation surface 4, preventing rock debris deposition, thereby improving the slag removal effect. Therefore, the slag removal effect of the present invention is not limited by the excavation diameter and the rotation speed of the excavation device 1, thus enabling timely removal of rock debris from the bottom of large-diameter vertical shafts.

[0037] Specifically, the excavation device 1 can excavate the excavation face 4 from the outside in, meaning the excavation radius of the excavation device 1 gradually decreases, or it can excavate the excavation face 4 from the inside out, meaning the excavation radius of the excavation device 1 gradually increases. The swing structure 22 has a swing axis, which can drive the slag discharge structure 21 to reciprocate around the swing axis within the radius of the excavation face 4. In order to discharge the rock debris generated by the excavation device 1 in a timely manner, the swing structure 22 adaptively swings the slag discharge structure 21 according to the excavation radius of the excavation device 1, so that the distance between the slag inlet end of the slag discharge structure 21, that is, the end closest to the excavation face 4, and the center of the excavation face 4 is close to or equal to the excavation radius of the excavation device 1. Thus, under the rotation of the excavation device 1, the slag discharge structure 21 is driven to rotate, so that the slag discharge structure 21 can rotate to the area excavated by the excavation device 1 and transfer the rock debris.

[0038] like Figure 1 and Figure 2 As shown, the excavation device 1 includes a main drive mechanism 11 and an excavation mechanism 12. Both the excavation mechanism 12 and the slag removal mechanism 2 are mounted on the main drive mechanism 11 and are arranged at intervals along the circumferential direction C of the excavation face 4. The main drive mechanism 11 can drive the slag removal mechanism 2 and the excavation mechanism 12 to rotate synchronously along the circumferential direction C of the excavation face 4 of the excavation device 1. A rotary connecting plate 102 is provided at the bottom of the main drive mechanism 11, and both the excavation mechanism 12 and the slag removal mechanism 2 are mounted on this rotary connecting plate 102. The excavation device 1 also includes a propulsion mechanism 13, which is connected to the main drive mechanism 11. The propulsion mechanism 13 drives the main drive mechanism 11 and its connected excavation mechanism 12 downwards, realizing the excavation of the excavation device 1 in the depth direction Z.

[0039] Specifically, the number of slag removal mechanisms can be as simple as one, or as in the embodiment of the present invention, as two slag removal mechanisms 2' and 2' can be provided. Alternatively, three, four, or more mechanisms can be provided if the installation space allows. Slag removal mechanisms 2' and 2' are arranged at intervals along the circumferential direction C of the excavation surface 4. The main drive mechanism 11 of the excavation device 1 drives slag removal mechanisms 2' and 2' to rotate along the circumferential direction C of the excavation surface 4, thereby sequentially removing slag from the area excavated by the excavation mechanism 12, thus further improving the slag removal effect. Slag removal mechanisms 2' and 2' can adopt the same or different slag removal methods depending on different working conditions. The excavation mechanism 12 includes an excavation arm 101 and a second swing telescopic member 106. The excavation arm 101 is hinged to the main drive mechanism 11 via a second hinge shaft 105 and connected to the main drive mechanism 11 via the second swing telescopic member 106. The second swing telescopic member 106 can drive the excavation arm 101 to swing radially R along the excavation surface 4. The excavating arm 101 has the same specific structure as the prior art, and will not be described in detail here. The propulsion mechanism 13 includes multiple propulsion cylinders 104, which are arranged at intervals along the circumference C of the excavation surface 4. The propulsion mechanism 13 has the same specific structure as the prior art, and will not be described in detail here.

[0040] like Figure 1 As shown, the swing structure 22 includes a swing mounting frame 201 and a first swing telescopic member 205. The swing mounting frame 201 is hinged to the excavation device 1 and connected to the main drive mechanism 11 through the first swing telescopic member 205. The slag discharge structure 21 is mounted on the swing mounting frame 201. Under the telescopic drive of the swing telescopic member, the swing mounting frame 201 drives the slag discharge structure 21 to swing in the radial direction R of the excavation face 4. Specifically, the top of the swing mounting frame 201 is provided with a mounting seat. One end of the mounting seat near the center of the rotary connecting plate 102 is hinged to the rotary connecting plate 102 through a first hinge shaft 204 arranged along the swing axis. The other end of the mounting seat away from the center of the rotary connecting plate 102 is hinged to the bottom end of the first swing telescopic member 205. The top end of the first swing telescopic member 205 is hinged to the rotary connecting plate 102. The first swing telescopic member 205 can be a telescopic cylinder, an electric telescopic rod, or other telescopic drive structure.

[0041] like Figure 1 and Figure 2As shown, in this embodiment of the invention, the slag discharge mechanism 2 further includes a distance adjustment structure 23. The slag discharge structure 21 slides in cooperation with the swing structure 22 along the vertical direction of the swing axis. The distance adjustment structure 23 is arranged along the vertical direction of the swing axis and connects the slag discharge structure 21 and the swing structure 22. The excavation surface 4 generated by the excavation device 1 is generally a concave structure with a lower center and higher periphery. By driving the slag discharge structure 21 to slide along the vertical direction of the swing axis through the distance adjustment structure 23, the distance between the slag discharge structure 21 and the excavation surface 4 is adjusted, so that the movement trajectory formed by the slag discharge structure 21 in the radial direction R of the excavation surface 4 under the cooperative drive of the swing structure 22 and the distance adjustment structure 23 can match the excavation surface 4, and the slag inlet end of the slag discharge structure 21 can always be close to the excavation surface 4, ensuring that the rock debris can smoothly enter the slag discharge structure 21. Specifically, the slag discharge structure 21 slides in cooperation with the swing mounting frame 201 along the vertical direction of the swing axis. The distance adjustment structure 23 may include multiple distance adjustment cylinders 203, or multiple electric telescopic rods or other telescopic drive structures.

[0042] like Figure 1 As shown, in some embodiments of the present invention, the slag removal device further includes a slag discharge mechanism 3, which can pass through the main drive mechanism 11 and extend above the central area of ​​the excavation face 4. The slag discharge mechanism 3 can transport the rock debris to the outside of the well. Specifically, the rock debris located outside the central area on the excavation face 4 can be concentrated to the central area through the slag discharge structure 21, and then the rock debris concentrated in the central area can be transported to the outside of the well through the slag discharge mechanism 3; and / or the rock debris located outside the central area on the excavation face 4 can be directly transferred to the slag discharge mechanism 3 through the slag discharge structure 21, and then the rock debris in the central area and the rock debris transferred by the slag discharge structure 21 can be transported to the outside of the well through the slag discharge mechanism 3.

[0043] Specifically, in combination Figure 2 As shown, the main drive mechanism 11 is provided with a central channel 107, and the slag discharge mechanism 3 extends from the central channel 107 to the top of the central area of ​​the excavation face 4.

[0044] like Figure 1 As shown, the slag discharge mechanism 2 also includes a slag chute structure 206, through which the slag discharged by the slag discharge structure 21 can slide along the slag chute structure 206 into the slag receiving structure 303 or the central area of ​​the slag discharge mechanism 3. Specifically, the slag chute structure 206 is installed on the swing mounting frame 201 and located below the slag discharge end of the slag discharge structure 21. The slag chute structure 206 is generally a trough structure.

[0045] like Figure 1As shown, in one embodiment of the present invention, the slag discharge mechanism 3 includes a slag lifting structure 31 and a lifting structure 33. The slag lifting structure 31 slides along the depth direction Z of the excavation surface 4 with the main drive mechanism 11 and is connected to the main drive mechanism 11 through the lifting structure 33. The lifting structure 33 can drive the slag lifting structure 31 to slide along the depth direction of the excavation surface 4. Specifically, the slag lifting structure 31 is provided with a slag receiving structure 303 for cooperating with the slag chute structure 206, so that the slag discharged by the slag discharge structure 21 can enter the slag lifting structure 31 from the slag receiving structure 303 under the guidance of the slag chute structure 206. The slag receiving structure 303 is generally a conical trough structure that extends gradually from bottom to top.

[0046] The lifting structure 33 drives the rock cuttings lifting structure 31 to slide downwards to a region close to the center of the excavation face 4. The excavation mechanism 12 excavates the area of ​​the excavation face 4 surrounding the rock cuttings lifting structure 31, and transfers the rock cuttings on the excavation face 4 through the slag discharge structure 21. Under the guidance of the slag chute structure 206, the rock cuttings are concentrated in the center region and / or directly transferred to the rock cuttings lifting structure 31, and then the rock cuttings are carried out of the well by the rock cuttings lifting structure 31. When the excavation mechanism 12 excavates the center region of the excavation face 4, in order to avoid interference between the slag discharge mechanism 3 and the excavation mechanism 12, the lifting structure 33 drives the rock cuttings lifting structure 31 to slide upwards, thereby making room above the excavation face 4. After the excavation mechanism 12 excavates the center region, it swings outwards a certain distance to make room in the center region of the excavation face 4. The lifting structure 33 then drives the rock cuttings lifting structure 31 to slide downwards to a region close to the center of the excavation face 4, thereby carrying the rock cuttings from the center region out of the well by the rock cuttings lifting structure 31.

[0047] Specifically, in combination Figure 2 As shown, the rock debris lifting structure 31 slides with the central channel 107 along the depth direction Z (i.e., the axial direction of the shaft) of the excavation face 4 via the sliding structure 301. The lifting structure 33 includes multiple lifting cylinders 302, which are mounted on the main platform 103 of the main drive mechanism 11 and arranged around the central channel 107.

[0048] In this embodiment of the present invention, the specific operation method of the slag discharge device is as follows:

[0049] The excavating arm 101, under the combined action of the propulsion mechanism 13, the main drive mechanism 11, and the second swing telescopic component 106, covers the entire excavation face 4, generating rock debris of a certain thickness on the excavation face 4. During the excavation process outside the central area of ​​the excavation face 4, the slag discharge structure 21, mounted on the swing mounting frame 201, simultaneously performs slag discharge operations under the combined action of the first swing telescopic component 205, the distance adjustment structure 23, and the main drive mechanism 11. The lifting structure 33 lowers the slag lifting structure 31 above the central area, thereby facilitating the discharge... The slag structure 21 uses the slag chute structure 206 to guide the rock slag outside the central area of ​​the excavation face 4 into the slag receiving structure 303 of the rock slag lifting structure 31, and then the rock slag is transported out of the well through the rock slag lifting structure 31; during the excavation of the central area of ​​the excavation face 4 by the excavation arm 101, the lifting structure 33 drives the rock slag lifting structure 31 to rise and avoid the excavation arm 101. After the excavation arm 101 completes the excavation of the central area and swings outward, the lifting structure 33 drives the rock slag lifting structure 31 to descend and extend into the rock slag in the central area, and then the rock slag is transported out of the well through the rock slag lifting structure 31.

[0050] like Figure 1 As shown, in another embodiment of the present invention, the slag removal mechanism 3 includes a grab bucket 32. The slag removal structure 21 concentrates the rock slag into the central area, and the grab bucket 32 ​​passes through the main drive mechanism 11 to grab the rock slag concentrated in the central area and remove it from the well. Specifically, the grab bucket 32, under the hoisting of the suspension device, passes through the central channel 107 and extends into the rock slag in the central area, thereby grabbing the rock slag in the central area and removing it from the well.

[0051] In this embodiment of the present invention, the specific operation method of the slag discharge device is as follows:

[0052] The excavating arm 101, under the combined action of the propulsion mechanism 13, the main drive mechanism 11, and the second swing telescopic component 106, covers the entire excavation face 4, resulting in a certain thickness of rock debris on the excavation face 4. During the excavation process outside the central area of ​​the excavation face 4, the slag discharge structure 21, mounted on the swing mounting frame 201, simultaneously performs slag discharge operations under the combined action of the first swing telescopic component 205, the distance adjustment structure 23, and the main drive mechanism 11. The slag discharge structure 21 utilizes the slag chute structure 206 to discharge slag from the excavation face 4. Rock debris outside the central area is concentrated in the central area. At the same time, the grab bucket 32, under the hoisting of the suspension device, passes through the central channel 107 and extends into the rock debris in the central area, and then transports the rock debris out of the well through the grab bucket 32. During the excavation of the central area of ​​the excavation face 4 by the excavation arm 101, the grab bucket 32 ​​is raised under the hoisting of the suspension device to avoid the excavation arm 101. After the excavation arm 101 completes the excavation of the central area and swings outward, the grab bucket 32 ​​is lowered under the hoisting of the suspension device and extends into the rock debris in the central area, and then transports the rock debris out of the well through the grab bucket 32.

[0053] like Figure 3 As shown, the slag discharge structure 21 can be a scraper conveyor 202. For example... Figure 4 The slag removal structure 21 shown can also be a bucket wheel conveyor 207. When constructing in waterless or low-water strata, the slag removal structure 21 can also be a high-pressure air jet device, which uses airflow to collect rock debris outside the central area of ​​the excavation face 4 towards the central area.

[0054] like Figure 1 and Figure 5 As shown, in some other embodiments of the present invention, the excavation device 1 is used in water-rich strata. The slag discharge device can dismantle the slag discharge mechanism 3. The slag discharge structure 21, under the combined action of the swing structure 22, the distance adjustment structure 23 and the main drive mechanism 11, forms a slag discharge range that covers the entire excavation face 4, thereby directly completing the timely slag discharge of the entire excavation face 4 through the slag discharge structure 21.

[0055] Specifically, in combination Figure 2 and Figure 5 As shown, at least one slag removal mechanism 2' has a slag removal structure 21 that is a slag extraction structure. The slag extraction structure includes a mud pump 208 and a slag discharge pipe 209. The mud pump 208 can draw the rock debris from the excavation face 4 into the slag discharge pipe 209 and pump the rock debris from the slag discharge pipe 209 out of the well. To improve the slag removal effect of the slag extraction structure, at least another slag removal mechanism 2's slag removal structure 21 is a slag stirring structure. The slag stirring structure is located between the slag extraction structure and the excavation mechanism 12 in the rotation direction of the excavation device 1. The slag stirring structure is used to stir the rock debris on the excavation face 4, thereby preventing rock debris deposition and facilitating the slag extraction structure to extract the rock debris out of the well. Figure 3 As shown, the slag mixing structure can be a scraper conveyor 202 or a water jet generator.

[0056] In this embodiment of the present invention, the specific operation method of the slag discharge device is as follows:

[0057] The excavation arm 101, under the combined action of the propulsion mechanism 13, the main drive mechanism 11, and the second swing telescopic component 106, covers the entire excavation face 4, resulting in a certain thickness of rock debris on the excavation face 4. During the excavation process, the slag-stirring structure installed on at least one swing mounting frame 201 simultaneously stirs the rock debris under the combined action of the corresponding first swing telescopic component 205, the distance adjustment structure 23, and the main drive mechanism 11. The slag-drawing structure installed on at least another swing mounting frame 201 simultaneously draws the rock debris stirred by the slag-stirring structure out of the well under the combined action of the corresponding first swing telescopic component 205, the distance adjustment structure 23, and the main drive mechanism 11.

[0058] Implementation Method 2

[0059] like Figure 1 and Figure 2 As shown, the present invention also provides a shaft boring machine, including an excavation device 1 and a slag removal device. The slag removal device in this embodiment has the same specific structure, working principle and beneficial effects as the slag removal device in embodiment one, and will not be described again here.

[0060] In an embodiment of the present invention, the excavation device 1 includes a main drive mechanism 11 and an excavation mechanism 12. The excavation mechanism 12 includes an excavation arm 101 and a second swing telescopic member 106. The excavation arm 101 is hinged to the main drive mechanism 11 and connected to the main drive mechanism 11 through the second swing telescopic member 106. The second swing telescopic member 106 can drive the excavation arm 101 to swing radially in the excavation surface 4.

Those skilled in the art can make various modifications or variations to the embodiments of the present invention based on the content disclosed in the application documents without departing from the spirit and scope of the present invention.
