Description

Technical Field

[0001] The utility model relates to the technical field of shaft boring, in particular to a shaft boring machine quarrying device and a shaft boring machine. Background Art

[0002] In recent years, with the increasing speed of underground space development and the increasing scale of utilization, there are more and more caisson projects. As a new type of caisson construction equipment, the shaft boring machine has unique technical advantages such as safety, high efficiency, small site occupation, wide geological adaptability, and little impact on the surrounding environment compared to other traditional methods and equipment. However, with the increase in the diameter and depth of caisson construction, the geological conditions of the caisson are becoming more and more complicated. When the shaft boring machine is excavating in strata such as water-rich sand and gravel with high rock content, large particle size, and high hardness, it often inhales pebbles or large-size rock blocks, resulting in accidents such as slurry pipe blockage or slurry pump damage. Once the drainage is delayed, the shaft boring machine will be forced to stop excavation, and the main machine needs to be lifted out of the shaft to manually clean the slurry pipe or slurry pump. The slurry discharge capacity of the shaft boring machine is seriously restricted.

[0003] At present, vertical shaft boring machines mostly use mud pump suction to discharge slag, but this type of slag discharge method has disadvantages such as being unable to discharge large-diameter pebbles and large hard rocks. There are still problems such as pipe blockage and slag accumulation at the bottom of the well, which affects the excavation efficiency.

[0052] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0053] The words "upper", "lower", "top", "bottom" and so on which indicate direction in this utility model are all Figure 2 The directions such as “upper”, “lower”, “top” and “bottom” are intended to clearly illustrate the positional relationship or connection relationship between the various parts without limiting the specific directions.

[0054] Implementation Method 1

[0055] like Figures 1 to 4 As shown, the utility model provides a quarrying device for a shaft boring machine, which is arranged between a slurry pump 7 and a slag suction box 6 of the shaft boring machine, and comprises a slurry discharge pipe 1, a rockfall pipe 2 and a stone storage box 3, wherein the slurry discharge pipe 1 is used to be connected to the slurry pump 7 and the slag suction box 6 respectively in a switchable manner, and the rockfall pipe 2 is arranged on the side wall of the slurry discharge pipe 1, and the rockfall pipe 2 at least has a slag inlet and a slag outlet, and the slag inlet of the rockfall pipe 2 is connected to the inside of the slurry discharge pipe 1; the stone storage box 3 at least has an inlet and an openable and closable external discharge port 303, and the inlet of the stone storage box 3 is connected to the slag outlet of the rockfall pipe 2; at least part of the slag entering the slurry discharge pipe 1 from the slag suction box 6 can enter the stone storage box 3 through the rockfall pipe 2, and the slag stored in the stone storage box 3 can be discharged by opening the external discharge port 303.

[0056] In the utility model, the quarrying device of the shaft boring machine is arranged between the slurry pump 7 and the slag suction box 6 of the shaft boring machine, wherein the quarrying device of the shaft boring machine comprises a slurry discharge pipe 1 which is used to be connected and disconnected with the slurry pump 7 and the slag suction box 6 respectively, and a rockfall pipe 2 which is arranged on the side wall of the slurry discharge pipe 1, the slag inlet of the rockfall pipe 2 is connected with the inside of the slurry discharge pipe 1, and the slag outlet of the rockfall pipe 2 is connected with the entrance of the stone storage box 3. During the excavation and slag discharge process, part of the slag (small-size slag) can be discharged through the slag suction box 6, the slurry discharge pipe 1 and the slurry pump 7 in sequence, while the other part of the slag (large-size slag) will be discharged through the slurry discharge pipe 1 enters into the rockfall pipe 2, and then enters into the rock storage box 3 through the rockfall pipe 2, and collects, stores and centrally discharges the slag stored in the rock storage box 3 by opening the external discharge port 303 of the rock storage box 3, thereby preventing large-size slag from entering the slurry pump 7 and the slurry discharge pipe 701 connected to the slag outlet of the slurry pump 7, avoiding damage to the slurry pump 7 or blockage of the slurry discharge pipe 701, ensuring smooth external discharge of slag, ensuring that the tunnel boring machine can still smoothly excavate even in the formations such as water-rich sand and gravel with large rock content, large particle size and high hardness, effectively improving the excavation efficiency of the shaft tunnel boring machine, and enabling the shaft tunnel boring machine to adapt to various geological conditions.

[0057] Among them, small-size slag and large-size slag can be determined according to the capacity of the slurry pump 7 for slag to pass through and the diameter of the slurry discharge pipe 701. Slag that is not likely to cause damage to the slurry pump 7 and blockage of the slurry discharge pipe 701 can be considered as small-size slag, and small-size slag can be directly discharged through the slurry pump 7 and the slurry discharge pipe 701 without passing through the rockfall pipe 2 and the stone storage box 3 in the utility model. All slag except small-size slag can be considered as large-size slag (slag that is likely to cause damage to the slurry pump 7 and blockage of the slurry discharge pipe 701). The specific particle size range of small-size slag and large-size slag is determined according to the actual equipment and is not limited here.

[0058] In the present invention, the slurry pump 7 can also be replaced by a vacuum pump or a mud pump provided on the cutting arm 5 of the shaft boring machine, which can be used to discharge slag and stone.

[0059] In an optional embodiment of the present invention, Figure 1 , Figure 2As shown, the slurry discharge pipe 1 includes a slurry discharge pipe body 101, which is a straight cylinder with openings at both ends. One end opening of the slurry discharge pipe body 101 is connected to the slag inlet of the slurry pump 7, and a first valve member 104 is arranged between the end opening of the slurry discharge pipe body 101 and the slag inlet of the slurry pump 7, the other end opening of the slurry discharge pipe body 101 is connected to the slag outlet of the slag suction box 6, and a second valve member 103 is arranged between the end opening of the slurry discharge pipe body 101 and the slag outlet of the slag suction box 6. The first valve member 104 controls the on-off state between the slurry discharge pipe body 101 and the slag inlet of the slurry pump 7, so that the slag and mud in the slurry discharge pipe body 101 can be controlled to enter the slurry pump 7 for external discharge; the second valve member 103 controls the on-off state between the slurry discharge pipe body 101 and the slag outlet of the slag suction box 6, so that the slag and mud in the slag suction box 6 can be controlled to enter the slurry discharge pipe body 101, so as to achieve the purpose of the slurry discharge pipeline 1 being connected to the slurry pump 7 and the slag suction box 6 in an on-off manner. When the slag in the stone storage box 3 is discharged through the external discharge port 303, the first valve member 104 and the second valve member 103 are both in a closed state. Among them, the first valve member 104 and the second valve member 103 can be, but not limited to, on-off valves.

[0060] Further, such as Figure 1 , Figure 2 As shown, a first grid plate 102 is provided between an opening at one end of the slurry discharge pipe body 101 and the inlet of the first valve member 104. The first grid plate 102 can block large-sized debris that may damage the slurry pump 7 and block the slurry discharge pipe 701 in the slurry discharge pipe body 101. Such large-sized debris will be stored and discharged centrally through the rockfall pipe 2 and the stone storage box 3 in turn, and will not enter the slurry pump 7, thereby ensuring the long-term and stable operation of the slag discharge equipment in the shaft boring machine and improving the excavation efficiency.

[0061] In an optional embodiment of the present invention, Figure 1 , Figure 2 As shown, at least one first flushing joint 105 is provided on the slurry discharge pipe body 101. The first flushing joint 105 and the flushing pipeline (not shown) can be used to flush the slurry discharge pipe body 101 through the first flushing joint 105, so as to clean the mud and slag retained in the slurry discharge pipe body 101.

[0062] Further, such as Figure 1 , Figure 2 As shown, the first flushing joint 105 is located on the side wall of the slurry discharge pipe 1 opposite to the slag inlet of the rockfall pipe 2. The first flushing joint 105 flushes water into the slurry discharge pipe body 101, and the slag in the slurry discharge pipe body 101 can be flushed into the rockfall pipe 2 by the water flow, ensuring that the slag enters the rockfall pipe 2 smoothly.

[0063] In an optional embodiment of the present invention, Figure 1 , Figure 2 As shown, the rockfall pipe 2 includes a rockfall pipe body 201, which is in the shape of a straight tube. One end of the rockfall pipe body 201 is connected to the slurry discharge pipe 1, and the other end of the rockfall pipe body 201 is connected to the stone storage box 3, so that the rockfall pipe 2 is fixed between the slurry discharge pipe 1 and the stone storage box 3. A conical first guide plate 202 is arranged in the rockfall pipe body 201. The cross-sectional area of ​​the first guide plate 202 gradually decreases from the slurry discharge pipe 1 to the stone storage box 3. The expanded end of the first guide plate 202 (i.e., the end with a larger diameter of the first guide plate 202) is connected to the slurry discharge pipe 1 to form a slag inlet, and the contracted end of the first guide plate 202 (i.e., the end with a smaller diameter of the first guide plate 202) is connected to the stone storage box 3 to form a slag outlet. The arrangement of the first guide plate 202 can guide the slag, ensuring that the slag in the slurry discharge pipe 1 can fall smoothly into the stone storage box 3.

[0064] In this embodiment, the cross section of the first guide plate 202 is circular, and the diameter of the slag inlet is greater than the diameter of the slag outlet.

[0065] In an optional embodiment of the utility model, in order to realize the openability and closability of the external discharge port 303, an openable and closable stone discharge door can be provided at the external discharge port 303, and the opening or closing of the stone discharge door can be automatically controlled, thereby realizing the automatic discharge of the slag in the stone storage box 3. The stone discharge door can be connected to a driving element such as a push cylinder to realize the push and pull action of the stone discharge door, thereby achieving the purpose of controlling the opening or closing of the stone discharge door; of course, the stone discharge door can also be just an on-off valve, and the opening or closing of the external discharge port 303 is controlled by the on-off valve.

[0066] In an optional embodiment of the present invention, Figures 1 to 3 As shown, the stone storage box 3 includes a box body 301, an inlet and an outer discharge port 303 of the box body 301 are respectively located on two opposite side walls of the box body 301, and a conical second guide plate 302 is arranged in the box body 301. The cross-sectional area of ​​the second guide plate 302 gradually decreases from the rock falling pipe 2 to the stone discharge door. The expanded end of the second guide plate 302 (that is, the end with a larger diameter of the second guide plate 302) can be connected to the inner wall of the box body 301 adjacent to the side wall where the outer discharge port 303 is located, so as to ensure that the slag and stone falling into the box body 301 from the inlet of the box body 301 can be smoothly guided to the outer discharge port 303, so as to smoothly discharge the slag and stone; the contracted end of the second guide plate 302 (that is, the end with a smaller diameter of the second guide plate 302) is connected to the stone storage box 3 to form the outer discharge port 303.

[0067] In an optional embodiment of the present invention, Figure 1 , Figure 2As shown, at least one second flushing joint 304 is provided on the box body 301. The second flushing joint 304 and the flushing pipeline (not shown) can be used to flush into the box body 301 through the second flushing joint 304, so as to clean the mud and slag retained in the box body 301.

[0068] Further, such as Figure 1 , Figure 2 As shown, there are multiple second flushing joints 304, at least two of which are located on two adjacent side walls of the box body 301, and at least one second flushing joint 304 is located on the side wall of the box body 301 opposite to the external discharge port 303. Thus, a cross water flow is formed, which can not only fully flush the inside of the box body 301, but also flush the debris in the box body 301 out of the external discharge port 303 through the water flow, ensuring that the debris can be completely discharged.

[0069] In an optional embodiment of the present invention, Figure 1 , Figure 2 As shown, a second grid plate 601 is provided at the connection position between the slurry discharge pipe 1 and the slag suction box 6 or at the slag outlet of the slag suction box 6. Before the slag in the slag suction box 6 enters the slurry discharge pipe 1, the slag is screened by the second grid plate 601, and part of the large-size slag is blocked in the slag suction box 6. The large-size slag remaining in the slag suction box 6 will continue to be crushed by the cutting drum 8 of the tunneling machine until the slag is crushed to pass through the second grid plate 601. Among them, the cross-sectional area of ​​the through hole on the second grid plate 601 is larger than the cross-sectional area of ​​the through hole on the first grid plate 102, so that the slag is screened in two stages, ensuring that the particle size of the slag discharged is gradually reduced, thereby avoiding damage to the slurry pump 7 or blockage of the slurry discharge pipe 701.

[0070] In an optional embodiment of the present invention, Figures 1 to 4 As shown, the slurry discharge pipe 1 is used to be fixed on the cutting arm 5 of the shaft boring machine. The cutting arm 5 can drive the shaft boring machine quarrying device of the utility model to rotate a certain angle, so that when the stone storage box 3 is in the state of slag stone external discharge, the stone storage box 3 can be driven by the cutting arm 5 to the external discharge port 303 toward the bottom of the shaft, so that the slag stone can be smoothly discharged from the stone storage box 3 under the action of its own gravity and fall to the preset position at the bottom of the shaft.

[0071] The characteristics and advantages of the quarrying device of the shaft boring machine of the utility model are:

[0072] 1. The quarrying device of the shaft boring machine can store some large-sized slag in the slag storage box 3, and can collect, store and centrally discharge the slag stored in the slag storage box 3 through the external discharge port 303, thereby preventing large-sized slag from entering the slurry pump 7 and the slurry discharge pipe 701 connected to the slag outlet of the slurry pump 7, avoiding damage to the slurry pump 7 or blockage of the slurry discharge pipe 701, and ensuring smooth discharge of slag.

[0073] 2. The quarrying device of the shaft boring machine can ensure that the boring machine can still excavate smoothly even in strata with high rock content, large particle size and high hardness, such as water-rich sand and gravel, effectively improving the excavation efficiency of the shaft boring machine and enabling the shaft boring machine to adapt to various geological conditions.

[0074] Implementation Method 2

[0075] like Figure 4 As shown, the utility model provides a shaft boring machine, which includes:

[0076] A tunnel boring machine body 9, which is fixed to the inner wall of the shaft;

[0077] A cutting arm 5, the cutting arm 5 is swingably arranged on the tunnel boring machine body 9;

[0078] A cutting drum 8, which is arranged at the end of the cutting arm 5;

[0079] A slag suction box 6, which is arranged at the end of the cutting arm 5 and close to the cutting drum 8;

[0080] A slurry pump 7, which is arranged on the cutting arm 5;

[0081] The above-mentioned shaft boring machine quarrying device 100 is arranged on the cutting arm 5 and is located between the slurry pump 7 and the slag suction box 6 .

[0082] In an optional embodiment of the present invention, Figure 4 As shown, the slurry outlet of the slurry pump 7 is connected to the slurry discharge pipe 701.

[0083] In an optional embodiment of the present invention, Figure 4 As shown, the shaft boring machine further includes a grab 4, which is lowered into the shaft to collect and discharge the slag discharged from the shaft boring machine quarrying device 100. Of course, the grab 4 can also be replaced by a bucket or bucket elevator and other equipment, which can discharge the slag at the bottom of the shaft to the outside of the shaft.

[0084] The specific working process of the utility model is as follows: before the mud and slag enter the slurry discharge pipe 1 from the slag suction box 6, a part of the large-size slag (pebbles and rocks) is filtered out by the second grid plate 601, and the part of the large-size slag is retained in the slag suction box 6 and repeatedly crushed by the cutting drum 8 until the particle size of the slag can pass through the second grid plate 601. The mud and slag entering the slurry discharge pipe 1, the mud and part of the small-size slag can be sucked into the slurry discharge pipe 701 by the slurry pump 7 through the first grid plate 102 for external discharge; and the large-size slag retained in the slag suction box 6 falls into the stone storage box 3 through the rock drop pipe 2 under the action of gravity and the guidance of the first guide plate 202 and the second guide plate 302. Due to the setting of the second guide plate 302, the slag in the stone storage box 3 is tilted and accumulated to the side of the external discharge port 303, and the slag in the stone storage box 3 is not easy to be thrown back to the slurry discharge pipe 1 when the cutting arm 5 swings. After the amount of slag stored in the stone storage box 3 reaches a preset threshold (or the stone storage box 3 is filled with slag), the external discharge port 303 is opened, and the slag in the stone storage box 3 is discharged from the stone storage box 3 through the external discharge port 303 along the second guide plate 302, and at the same time, the second flushing joint 304 flushes water into the stone storage box 3 to assist the stone storage box 3 in discharging slag. Before the stone storage box 3 discharges the slag, the cutting arm 5 needs to be swung to the outermost side of the well wall (i.e., swung to the maximum amplitude in the direction close to the inner wall of the shaft), so that the external discharge port 303 is as close to the bottom of the shaft as possible to obtain a better slag discharge angle, and the large-size slag discharged from the external discharge port 303 falls to the bottom of the well in a concentrated manner. After the cutting arm 5 is removed, the slag at the bottom of the well can be grabbed out of the well by the grab 4, and the fine slag and mud are discharged out of the well through the slurry pump 7 and the slurry discharge pipe 701.

[0085] The novel shaft boring machine used in the present invention has the same advantages and features as the shaft boring machine quarrying device described above, which will not be described in detail here.

[0086] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any technician in the field without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
