Description

Technical Field

[0001] This invention relates to the field of tunneling machine technology, and in particular to a split-type vertical shaft tunneling machine. Background Technology

[0002] The ESM expanded shaft boring machine is a customized design based on tunnel boring machine technology. Starting from the starting working shaft, the equipment is equipped with a conical excavation cutterhead with an excavation diameter of 7030mm. It utilizes the pilot shaft formed by the previous reverse shaft construction for self-flowing muck removal, achieving a highly efficient self-flowing muck removal method.

[0003] When existing shaft boring machines use the self-flowing muck removal method for tunneling, in actual construction, if they encounter large pieces of rock debris or wet clay, rock debris of uneven size, large pieces of rock debris that are not sufficiently broken in some areas, mud blockages formed by clay or water-bearing strata, or excessive instantaneous muck removal, the pilot shaft inlet or shaft wall is very easy to be blocked. If these blockages are not dealt with in time, serious problems such as cutterhead wear and jamming, overload of support shoes and propulsion system, or sudden gushing and collapse may occur.

The bottom of each constraint frame is in contact with the outside of the high-pressure nozzle on the same side.

[0007] In a preferred embodiment, the maintenance module includes an insertion slot located at the bottom of the support column. A pin is inserted into the insertion slot, and the bottom of the pin is fixedly connected to the upper side of the ball seat. Two symmetrical slots are formed at the bottom of the support column, and a limit block is engaged in each slot. The bottom of the limit block is fixedly connected to the upper side of the ball seat, and an annular groove is formed on the outside of the pin. Three rectangular slots are circumferentially distributed on the outside of the support column. Locking rods are slidably connected to each rectangular slot.

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0020] The split-type shaft boring machine disclosed in this invention is mainly used in scenarios where existing split-type shaft boring machines cannot effectively handle guide shaft blockage.

[0021] Reference Figures 1-9 A split-type vertical shaft tunneling machine includes a cutterhead 1, a pre-reserved slot 2 on the cutterhead 1, a bracket 3 bolted to the inner wall of the pre-reserved slot 2, a main hydraulic rod 4 bolted to the bottom of the bracket 3, and a guide shaft anti-blocking and auxiliary slag removal module 5 below the main hydraulic rod 4. A maintenance module 6 is installed in the pre-reserved slot 2. The guide shaft anti-blocking and auxiliary slag removal module 5 includes a hydraulic impact hammer 504, multiple pressure sensors 505 circumferentially distributed on the hydraulic impact hammer 504, a mounting platform 516 bolted to the upper side of the hydraulic impact hammer 504, multiple high-pressure nozzles 522 circumferentially distributed on the outside of the mounting platform 516, and a support column 501 bolted to the output end of the main hydraulic rod 4. Multiple industrial endoscopes 506 circumferentially distributed on the outside of the support column 501.

[0022] Specifically, the device utilizes the guide well anti-clogging and auxiliary slag discharge module 5 to promptly detect and clear the blockage location when the guide well is blocked by clay, stones, or rock debris due to the self-flowing slag discharge method. This ensures the smooth flow of slag discharge channels in the guide well during device operation, preventing cutterhead 1 from being worn or jammed due to blockage, and avoiding serious situations such as overload of the support shoe and propulsion system, or sudden gushing and collapse. This significantly improves the operating efficiency and service life of the device.

[0023] Reference Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 In a preferred embodiment, a movable frame 515 is slidably connected to the outside of the mounting platform 516. The movable frame 515 has a plurality of circular holes that are equidistantly distributed around the circumference. Each circular hole is provided with a branch pipe 521. The end of the branch pipe 521 near the hydraulic impact hammer 504 is connected to the high-pressure nozzle 522 on the same side. The outside of the mounting platform 516 is bolted to a ring track 520. A plurality of movable seats 523 that are equidistantly distributed around the circumference are slidably connected to the ring track 520. The outside of the movable seats 523 is rotatably connected to the outside of the high-pressure nozzle 522 on the same side through bearings. The outside of the plurality of movable seats 523 is bolted to an elastic spring 524. The end of the elastic spring 524 away from the movable seat 523 is bolted to the outside of the high-pressure nozzle 522 on the same side. The mounting platform 516 is equipped with a rotary joint 514 on its exterior. The ends of multiple branch pipes 521 that are away from the hydraulic impact hammer 504 are all connected to the rotary joint 514. The inner wall of the reserved groove 2 is connected to a high-pressure water pump 507 and a control cabinet 509 by bolts. The input end of the high-pressure water pump 507 is connected to a water supply pipe 508 through a flange. The output end of the high-pressure water pump 507 is connected to a liquid guide pipe 510 through a round pipe. The other end of the liquid guide pipe 510 is connected to the rotary joint 514. Both the water supply pipe 508 and the liquid guide pipe 510 are located inside the reserved groove 2. A ball seat 502 is provided below the support column 501. A ball head 503 is provided inside the ball seat 502. A support plate 512 is bolted to the outside of the ball head 503. A fixing frame 511 is bolted to the outside of the ball seat 502. Three secondary hydraulic rods 513 distributed circumferentially are rotatably connected to the outside of the fixing frame 511 through bearings. The output ends of the three secondary hydraulic rods 513 are rotatably connected to the upper side of the support plate 512 through bearings. The mounting platform 516 has an external notch. A drive motor 528 is bolted to the bottom inner wall of the notch. The output end of the drive motor 528 is connected to a gear 527 via a coupling. A fixed ring 518 is rotatably connected to the outside of the mounting platform 516 via a bearing. Two symmetrical secondary hydraulic rods 519 are bolted to the upper side of the fixed ring 518. The output ends of the two secondary hydraulic rods 519 are connected to the same internal gear ring 517 via a coupling. The internal gear ring 517 meshes with the gear 527, and the outside of the internal gear ring 517 is bolted to the inner wall of the movable frame 515. The bottom of the movable frame 515 has multiple circumferentially equidistant limiting grooves 526. The inner wall of the mounting platform 516 is engaged with the outside of the movable seat 523 on the same side. Multiple circumferentially equidistant constraint frames 525 are bolted to the outside of the movable frame 515. The bottom of each constraint frame 525 is in contact with the outside of the high-pressure nozzle 522 on the same side.

[0024] In specific application scenarios, the pilot well anti-clogging and auxiliary slag removal module 5 is mainly used in the pilot well anti-clogging and auxiliary slag removal process. Specifically, the module 5 uses a pressure sensor 505 integrated on the hydraulic impact hammer 504 to monitor the blockage status in real time. Once excessive pressure is detected, the control cabinet 509 automatically activates the main hydraulic rod 4 to push the impact hammer towards the blockage point. This achieves automatic identification and immediate handling of blockages, preventing further blockage from affecting tunneling efficiency. The industrial endoscope 506 provides visual observation of the blockage point, and the universal adjustment mechanism composed of the secondary hydraulic rod 513, ball seat 502, and ball head 503 allows the impact hammer and high-pressure nozzle to precisely align with the blockage location, improving the targeting and effectiveness of the clearing operation and reducing ineffective impacts and energy loss. The hydraulic impact hammer 504 powerfully impacts and breaks up large pieces of rock and hard stone in the blockage. The high-pressure water pump 507 pressurizes water and sprays it at high speed through the high-pressure nozzle 522 to impact, cut, and scour the clay. The combination of the two can efficiently handle mixed blockages, adapt to complex soil characteristics, and dredge more thoroughly; the secondary hydraulic rod 519 drives the internal gear ring 517 and the movable frame 515 to move up and down, so that the high-pressure nozzle 522 can swing vertically under the action of the elastic spring 524; the drive motor 528, gear 527 cooperate with the internal gear ring to drive the movable seat 523 to rotate horizontally along the ring track 520, so that the high-pressure nozzle revolves around the center of the mounting platform 516, thereby achieving full coverage of the inner wall of the guide well and the blockage points in the vertical, horizontal, and circumferential directions, without dead angle flushing and cutting, significantly improving the dredging quality.

[0025] Reference Figure 9In a preferred embodiment, the maintenance module 6 includes an insertion slot 601, which is located at the bottom of the support column 501. A pin 602 is inserted into the insertion slot 601, and the bottom of the pin 602 is bolted to the upper side of the ball seat 502. The bottom of the support column 501 has two symmetrical slots 605, each of which is fitted with a limiting block 604. The bottom of the limiting block 604 is bolted to the upper side of the ball seat 502. An annular groove 603 is formed on the outside of the pin 602. Three rectangular slots are equidistantly distributed around the circumference of the support column 501. Each of the three locking rods 606 is slidably connected to a locking rod 606. Each locking rod 606 has a slot. Each slot has a rectangular block 607 slidably connected to its inner wall. The outer side of each rectangular block 607 is bolted to the inner wall of the rectangular slot on the same side. Each rectangular block 607 has a spring 608 bolted to its outer side. The end of the spring 608 away from the rectangular block 607 is bolted to the inner wall of the slot on the same side. The outer side of the support column 501 is slidably connected to an annular frame 609. The inner wall of the annular frame 609 has a variable diameter tapered groove 610. The inner wall of the variable diameter tapered groove 610 is slidably connected to the outer side of each of the three locking rods 606. The support column 501 is bolted to the outside of a receiving frame 611. The inner wall of the receiving frame 611 is slidably connected to the outside of an annular frame 609. An annular groove is provided on the inner wall of the receiving frame 611. A sealing ring 613 is bolted to the annular groove. The inner wall of the sealing ring 613 is slidably connected to the outside of the annular frame 609. Two symmetrical sliding grooves are provided on the outside of the support column 501. The same supporting ring 614 is slidably connected in the two sliding grooves. The bottom of the supporting ring 614 is bolted to the upper side of the annular frame 609. A second spring 612 is surrounded on the outside of the support column 501. One end of the second spring 612 is bolted to the bottom inner wall of the receiving frame 611, and the other end is bolted to the bottom of the annular frame 609. The upper side of the support ring 614 is connected by bolts to two symmetrical semicircular blocks 615. Each of the two semicircular blocks 615 is provided with a cam 616. The outer side of each cam 616 is rotatably connected to a boss through a bearing. The boss and the opposite side of the support column 501 are connected by bolts. The outer side of the support column 501 has two symmetrical grooves. Each groove is provided with an operating rod 617. The end of the operating rod 617 near the boss is connected to the outer side of the cam 616 on the same side by bolts.

[0026] In specific application scenarios, the maintenance module 6 is mainly suitable for the maintenance process. The maintenance module 6 uses the operating rod 617 and cam 616 to press the semi-circular block 615, pushing the annular frame 609 to overcome the elastic force of the second spring 612 and slide into the receiving frame 611. This causes the variable diameter tapered groove 610 to release the pressure on the locking rod 606. Under the pull of the first spring 608, the locking rod 606 automatically disengages from the annular groove 603, thereby allowing the pin 602 to be pulled out from the insertion groove 601. This enables the lower structure below the support column 501 to be quickly separated from the cutter head 1. During reinstallation, the pin 602 is reinserted, the limit block 604 and the cutting groove 605 are locked together, and the locking rod 606 automatically resets and locks under the action of the first spring 608. No special tools are required. This mechanism significantly shortens maintenance downtime, reduces labor intensity, and ensures safe and reliable downhole operations by using mechanical self-locking.

[0027] Working principle: When the cutterhead 1 is excavating in the vertical shaft, the clay and rock debris generated by the cutterhead 1 will fall into the guide shaft. When the guide shaft is blocked by this clay and rock debris, the pressure sensor 505 integrated on the impact head of the hydraulic impact hammer 504 at the bottom of the cutterhead 1 will first come into contact with the blockage. When the pressure value detected by the pressure sensor 505 is too high, the control cabinet 509 will activate the main hydraulic rod 4, causing the output end of the main hydraulic rod 4 to gradually extend, pressing the hydraulic impact hammer 504 towards the blockage position. The industrial endoscope 506 will be activated. After the industrial endoscope 506 observes the blockage point, it will control the output end of the secondary hydraulic rod 513 to extend or shorten, thereby causing the ball head 503 in the ball seat 502 to drive the mounting platform 516 to turn towards the blockage point. 04 Upon reaching the blockage point, the hydraulic impact hammer 504 and high-pressure water pump 507 are activated. The impact head on the hydraulic impact hammer 504 continuously impacts the rock debris and stones in the blockage point. The high-pressure water pump 507 pressurizes the water delivered by the water pipe 508 and then delivers it to the rotary joint 514 through the liquid guide pipe 510. Depending on the extent of the blockage point, the secondary hydraulic rod 519 is activated. The output end of the secondary hydraulic rod 519 drives the internal gear ring 517 and the movable frame 515 to move up or down, thereby allowing the constraint frame 525 to move up and down. This allows the high-pressure nozzle 522 to rotate in the numerical direction under the elastic force of the elastic spring 524. The drive motor 528 is activated, and the drive motor 528 drives the gear 527 to rotate, causing the internal gear ring 517 to drive the movable frame 515 to rotate. Locked by the limiting groove 526, the movable seat 523 moves on the annular track 520 around the mounting platform 516. The rotating joint 514 delivers high-pressure water through the branch pipe 521 to the high-pressure nozzle 522, which sprays it outward at high speed to impact and cut the clay on the inner wall of the guide well and the blockage point, thereby clearing the blockage. When it is necessary to repair or replace the cutter head 1 and the equipment and structure on the cutter head 1, grasp and rotate the operating lever 617 downward, so that the cam 616 rotates with the rotation of the operating lever 617. Thus, the cam 616 gradually presses the semicircular block 615 during rotation, causing the semicircular block 615 to be squeezed and push the annular frame 609 downward. The frame 609 slides into the receiving frame 611 against the elastic force of the second spring 612, so that the narrower inner wall of the variable diameter tapered groove 610 no longer presses against the locking rod 606. Under the pull of the first spring 608, the locking rod 606 pops out and is no longer engaged with the annular groove 603, pulling the pin 602 out of the insertion groove 601, thereby completely separating the lower structure below the support column 501 from the cutter head 1. After the inspection and replacement of the cutter head 1 and each structure are completed, the pin 602 is reinserted into the insertion groove 601 and the limiting block 604 is locked with the cutting groove 605. The above steps are reversed to lock the pin 602 back into the support column 501.
