Description

Technical Field

[0001] The present invention relates to the technical field of tunnel pit construction equipment, in particular to a vertical excavation system. Background Art

[0002] In the disposal of high-level radioactive waste, burying high-level radioactive waste in stable geological bodies at a depth of 500m to 1000m is currently generally considered to be a technically feasible final disposal method internationally.

[0003] A disposal repository for high-level radioactive waste in a geological body usually includes a horizontal channel and a vertically downward disposal pit on the channel. The vertically downward disposal pit needs to be formed by using a vertical tunneling head to dig vertically downward in the rock mass, i.e., vertical tunneling operations.

[0004] Existing vertical tunneling devices, such as the high-level radioactive waste disposal pit tunneling system disclosed in the patent application number 202110375992.6, excavate the pit body through the main operating device that tunnels vertically downward, and drives the cutter disc on the tunneling head to rotate through a hydraulic motor to cut the rock through the cutter disc; because the vertical cutter disc will generate very strong vibrations when cutting the rock, this strong vibration will cause the main body of the vertical tunneling device to also generate strong vibrations; because the existing vertical tunneling device has fully automatic transfer pipe sections, in order to achieve automatic operation, it is equipped with a large number of high-precision sensors. When the main body of the vertical tunneling device vibrates, it will seriously affect the accuracy of the detection data of these high-precision sensors, thereby reducing the reliability of the overall operation of the device, causing the device to be unable to work stably and automatically, and seriously affecting the construction period.

[0005] In addition, strong vibration of the main body of the vertical tunneling device will make the tunneling accuracy very difficult to control, so the vertical tunneling device is required to have high vibration resistance.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] The purpose of the present invention is to provide a vertical tunneling system to solve the problems existing in the above-mentioned prior art and improve the tunneling accuracy of the vertical tunneling system.

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] like Figure 1-Figure 7 As shown, this embodiment provides a vertical tunneling system, including a main operating device, a vibration-proof unit, a pipe segment 18 conveying unit, a slag discharge system, an air supply system, a pipeline retracting and releasing device 10, a power supply, a hydraulic station 9 and a control device.

[0037] Among them, the main operating device can be moved and positioned at a certain position in the tunnel and dig vertically downward; the main operating device includes a frame 1, a propulsion system, a tunneling head 27, a pipe segment transfer platform 19 and a pipe segment transfer vehicle 17; the propulsion system includes a propulsion cylinder 2, a propulsion pressure plate 3 and at least four guide rods 20, the guide rods 20 are fixedly connected to the frame 1, and all the guide rods 20 are arranged parallel to each other, there are two propulsion cylinders 2, the propulsion cylinders 2 are fixedly connected to the frame 1, and the propulsion pressure plate 3 is slidably sleeved on each guide rod 20; the propulsion cylinder 2 presses and lifts the pipe segment through the propulsion pressure plate 3 The tunneling head 27 presses and lifts the pipe segments 18 coaxially stacked one by one above the tunneling head 27; the vehicle frame 1 is provided with a tunneling hole, through which the tunneling head 27 and the pipe segments 18 coaxially stacked one by one above the tunneling head 27 can pass; the pipe segment transfer platform 19 is fixed to the vehicle frame 1, and the pipe segment transfer vehicle 17 and the pipe segment transfer platform 19 are slidably engaged and can be positioned directly above the tunneling hole; the pipe segments 18 are detachably connected to the tunneling head 27 and to each other, and the bottom end of the push plate 3 is detachably connected to the tunneling head 27 and the pipe segments 18;

[0038] In this embodiment, the main operating device also includes a positioning external support system and a guide system; the positioning external support system includes at least four columns 4 arranged along the circumference of the excavation hole, and the top of each main column is fixedly provided with a top support cylinder 5 with a movable end extending toward the top wall of the tunnel. The positioning external support system also includes a side support cylinder 8 with a movable end extending toward the side wall of the tunnel and a ground support cylinder with a movable end extending toward the ground of the tunnel. At least one side support cylinder 8 is provided on each side of the frame 1, and the ground support cylinder is fixedly connected to the bottom end of the frame 1; the movable end ball of the top support cylinder 5 is hinged with an upper support plate 6, the movable end ball of the side support cylinder 8 is hinged with a side support plate 7, and the movable end ball of the ground support cylinder is hinged with a lower support plate 28.

[0039] The guidance system includes two laser rangefinders 11 mounted on the vehicle frame 1 and two laser targets mounted on top of the tunneling head 27. The laser targets correspond one-to-one with the laser rangefinders 11. The guidance system in this embodiment utilizes laser targets and laser rangefinder technology to perform real-time measurements of the mechanical excavation equipment in the disposal pit. The principle is as follows: By analyzing and calculating the position information of the two laser targets, the rotation angle and inclination angle of the tunneling head 27 are determined, thereby determining the specific position and posture of the tunneling head 27, facilitating precise control.

[0040] The pipe segment 18 conveying unit includes a transport vehicle 15, a mobile hoisting frame 14, a transverse frame 23 and a plurality of pipe segments 18 stored on the transport vehicle 15. The transport vehicle 15 is provided with a first guide rail 21 distributed along the length direction of the transport vehicle 15; the bottom end of the mobile hoisting frame 14 is slidably matched with the first guide rail 21; the top end of the mobile hoisting frame 14 is provided with a second guide rail 22 parallel to the first guide rail 21, and the transverse frame 23 is slidably matched with the second guide rail 22; the transverse frame 23 is fixed with a second guide rail 22 parallel to the first guide rail 21. The guide rail 22 is a vertical and horizontal third guide rail; the sliding seat 24 slides in cooperation with the third guide rail, and a lifting cylinder 25 is fixed on the sliding seat 24. The free end of the piston rod of the lifting cylinder 25 is used to lift the pipe segment 18. Specifically, a fixed plate 26 is fixed at the free end of the piston rod of the lifting cylinder 25, and the pipe segment 18 can be hung on the fixed plate 26 through a rope; part of the mobile lifting frame 14 and the pipe segment 18 lifted by the lifting cylinder 25 can be located above the pipe segment transfer vehicle 17.

[0041] In this embodiment, the length of the first guide rail 21 is equal to the length of the transport vehicle 15 .

[0042] The specific process of installing the pipe segment 18 on the tunneling head 27 through the pipe segment 18 conveying unit of the vertical tunneling system of this embodiment is as follows:

[0043] When the tunneling head 27 is fed downward to the point where a pipe segment 18 needs to be installed, the pushing plate 3 is disassembled from the tunneling head 27 (when no pipe segment 18 is installed above the tunneling head 27) or the uppermost pipe segment 18 above the tunneling head 27 (when a pipe segment 18 is installed above the tunneling head 27), and the pushing oil cylinder 2 is used to lift the pushing plate 3 to reserve space for installing the pipe segment 18; a pipe segment 18 is lifted by the lifting oil cylinder 25, and then the mobile lifting frame 14 is driven by the driving device to move along the first guide rail 21, and then the transverse frame 23 is made to slide along the second guide rail 22, and the sliding seat 24 is made to slide along the third guide rail, so that the lifted pipe segment 18 is located just above the pipe segment transfer vehicle 17, and then the pipe segment 18 is driven by the lifting oil cylinder 25 The lifted pipe segment 18 is lowered, and after the bottom end of the lifted pipe segment 18 contacts the top surface of the pipe segment transfer vehicle 17, the connection between the pipe segment 18 and the fixed plate 26 is removed, so that the lifting cylinder 25 no longer lifts the pipe segment 18, and then the fixed plate 26 is raised by the lifting cylinder 25, and then the pipe segment transfer vehicle 17 is slid to just above the tunneling head 27, and then the pipe segment 18 on the pipe segment transfer vehicle 17 is detachably connected to the thrust plate 3, and then the pipe segment transfer vehicle 17 is removed, and finally the added pipe segment 18 is detachably connected to the tunneling head 27 (when no pipe segment 18 is added above the tunneling head 27) or the other pipe segments 18 at the top of the tunneling head 27 (when a pipe segment 18 is added above the tunneling head 27).

[0044] The specific process of removing the uppermost pipe section 18 of the tunneling head 27 in the vertical tunneling system of this embodiment is as follows:

[0045] The main operating device has a structure for fixing the second pipe segment 18 from top to bottom. The structure is to set a fall-stop ring (not shown in the figure) at the mouth of the excavation hole, and a fall-stop wedge (not shown in the figure) that swings up and down and extends into the excavation hole is set on the upper end surface of the fall-stop ring. When the pipe segment 18 rises, it pushes the fall-stop wedge to swing up, and then the gravity of the fall-stop wedge causes it to swing and insert into the pin hole on the pipe segment 18 or the excavation head 27, thereby preventing the second pipe segment 18 and the pipe segment 18 and the excavation head 27 below it from falling; the fall-stop ring and the fall-stop wedge are both existing mature technologies in this field and will not be elaborated on. The specific structure and The principle can be found in the patent application number 202110375992.6; after fixing the tunneling head 27 or the second pipe segment 18 from top to bottom, the top pipe segment 18 and the thrust plate 3 are disassembled, and then the top pipe segment 18 is removed by the pipe segment transfer vehicle 17, and the pipe segment 18 is stored on the transport vehicle 15 through the lifting cylinder 25; after removing the top pipe segment 18, the thrust cylinder 2 drives the thrust plate 3 to descend and connect to the second pipe segment 18 for lifting, and the pipe segment 18 is removed in sequence. The removal operation of the pipe segment 18 is the reverse operation when the pipe segment 18 is fed in.

[0046] The vertical tunneling system of this embodiment utilizes manual assistance during the installation and removal of pipe segments 18, rather than fully automated operations. The provision of a semi-automatic pipe segment 18 conveying unit significantly reduces the number of high-precision sensors required within the unit, thereby avoiding the issue of inaccurate data from high-precision sensors due to overall system vibration, which can reduce system reliability and improve operational reliability. Furthermore, the pipe segment 18 conveying unit in the vertical tunneling system of the present invention is suitable for use in confined work areas. The unit can directly transfer pipe segments 18 to the pipe segment transfer vehicle 17, making it convenient to use.

[0047] The vibration isolation unit includes at least two vibration isolation mechanisms disposed within the tunneling head 27, distributed along the circumference of the tunneling head 27. Each isolation mechanism comprises an isolation cylinder 29 and a support plate 28, which is articulated with the hydraulic rod of the isolation cylinder 29. The isolation cylinder 29 is used to drive the support plate 28 to move radially along the tunneling head 27. The surfaces of the support plates 28 are provided with rollers configured to roll against the inner wall of the vertical tunneling shaft (i.e., the tunneling pit formed by the tunneling head 27). When the vibration isolation unit is in operation, the support plates 28 in each isolation mechanism extend and come into close contact with the inner wall of the vertical tunneling shaft, preventing the tunneling head 27 from vibrating radially along the vertical tunneling shaft during its downward movement. This significantly improves the tunneling head 27's vibration resistance, enabling stable downward tunneling and preventing the entire device from vibrating due to the intense vibration of the tunneling head 27.

[0048] The pipeline that drives and controls the tunneling head 27 is wound on the pipeline retracting and releasing device 10, and the inner end of the pipeline is connected to the control device, power supply and hydraulic station 9 through a rotary joint; the outer end of the pipeline is connected to the tunneling head 27 from the outer wall of the tunneling head 27 and the oblique channel of the tunneling head 27, and the outer wall of the pipe section 18 has a wiring groove to accommodate the pipeline.

[0049] The slag discharge system includes a slag suction device 16, a slag discharge channel 13 arranged on the frame 1, a first slag discharge pipe arranged in the tunneling head 27 and a second slag discharge pipe arranged in the pipe section 18. One end of the slag discharge channel 13 is connected to the slag suction device 16, and the other end is a slag suction port that is sealed and detachably connected to the first slag discharge pipe and the second slag discharge pipe. The slag suction port rises and falls with the thrust plate 3.

[0050] The air supply system includes an air supply fan and an air supply pipe 12. The air supply fan supplies air to the cutter head in the tunneling head 27 through the air supply pipe 12. Practice has proved that by setting up the air supply system, the air intake near the vertical tunneling shaft face is increased during the vacuum slag discharge process through the slag discharge system, so that the air intake carries the slag pieces on the face and is discharged through the first slag discharge pipe, the second slag discharge pipe and the slag discharge channel 13, thereby improving the slag discharge effect.

[0051] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
