Abstract
Description
Technical Field
[0001] This utility model relates to the field of TBM construction technology, specifically a TBM dismantling trailer locking device. Background Technology
[0002] During the dismantling of the inclined shaft TBM, after the main system is removed, the next step is to remove the ABS system that prevents the TBM from sliding down, and the supporting trailer must be locked to prevent it from slipping down.
[0003] Before dismantling the trailer, anti-slip locking must be performed first, so that the trailer system can be installed after dismantling in sections. Traditionally, the entire trailer is locked before dismantling, and each section must be re-locked, which increases the risk of slippage. To solve the safety of the trailer system during TBM dismantling, a trailer locking device specifically designed for TBM dismantling is required. Utility Model Content
[0004] To address the significant risks associated with removing individual trailer sections during TBM dismantling, particularly the risk of slippage, this invention provides a device for locking trailers during TBM dismantling in inclined shafts.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A TBM dismantling trailer locking device includes:
[0007] An anchor bolt, wherein the anchor bolt is fixedly embedded in the side of the tunnel wall and the connection part of the anchor bolt is exposed;
[0008] An adjustable pull rope assembly, one end of which is fixedly connected to the connection part of the anchor rod, and the other end of which is fixedly connected to the trailer.
[0009] The anchor rod is tilted at 13°-18° along the dragging direction of the adjustable rope assembly;
[0010] Each trailer is equipped with at least two sets of anchor bolts and adjustable tow rope assemblies.
[0011] As a further description of the above technical solution:
[0012] The adjustable pull rope assembly includes a hand chain hoist and a wire rope that are linearly connected.
[0013] As a further description of the above technical solution:
[0014] The trailer is fixedly equipped with a trailer column, and one end of the steel wire rope is fixedly connected to the trailer column.
[0015] As a further description of the above technical solution:
[0016] Each trailer is equipped with four sets of anchor bolts and adjustable tow rope assemblies, which are symmetrically distributed on both sides of the trailer.
[0017] As a further description of the above technical solution:
[0018] The anchor bolt includes:
[0019] The implantation part is fixed to the side of the implantation cavity wall, and the connecting part is integrally fixed to the end of the implantation part. The side of the connecting part is provided with an elongated hole and a round hole.
[0020] A transverse housing with a rectangular insertion hole on its back side. The transverse housing is fixedly installed on the side of the cavity wall by expansion screws, and the connecting part is located inside the rectangular insertion hole. A pin is installed between the transverse housing and the connecting part.
[0021] A support block is provided on the side of the connecting part near the adjustable pull rope assembly, and the support block is located inside the transverse housing;
[0022] The side of the support block is provided with an inclined support surface corresponding to the side of the connecting part.
[0023] As a further description of the above technical solution:
[0024] The side of the implanted part is provided with an inverted buckle.
[0025] The beneficial effects of this utility model are:
[0026] This invention, through the design of anchor bolts and an adjustable pull rope assembly, involves drilling holes in the tunnel wall at a predetermined location (in front of the trailer) during construction. The anchor bolts are then anchored to the tunnel wall, and the adjustable pull rope assembly is connected between the trailer and the anchor bolts. This effectively holds the trailer in place, locking it during TBM dismantling. The structure is simple; multiple anchor bolts can be installed in the early stages of construction, and the adjustable pull rope assembly is installed during dismantling. Furthermore, each trailer can be independently locked, avoiding the need for repeated adjustments to the locking device after trailer dismantling and ensuring construction safety. Tilting the anchor bolts 13°-18° along the pulling direction of the adjustable pull rope assembly ensures that the pulling direction of the assembly is essentially perpendicular to the length of the anchor bolt, guaranteeing sufficient pulling force.

[0033] Please refer to the attached document. Figures 1-3 This application illustrates a TBM dismantling trailer locking device provided in an embodiment of the present application. It is used to individually fix each trailer 1, lock each trailer separately, and lift each trailer section to the dismantling chamber for dismantling. After the trailer section locking system is in place, each trailer section is subjected to force independently. The dismantling of each trailer section does not affect the force on other trailers as they slide down, ensuring the safety and reliability of the subsequent dismantling of the supporting system. Specifically, it includes: anchor bolts 4 and adjustable rope assembly (mainly applicable in inclined shafts).
[0034] Anchor bolt 4 is fixedly embedded in the side of the tunnel wall 3, and the connecting part 402 of anchor bolt 4 is exposed for connecting one end of the adjustable rope assembly. That is, one end of the adjustable rope assembly is fixedly connected to the connecting part 402 of anchor bolt 4, and the other end of the adjustable rope assembly is fixedly connected to trailer 1.
[0035] The anchor rod 4 is tilted 13°-18° along the dragging direction of the adjustable rope assembly, so that the dragging direction of the adjustable rope assembly can be basically perpendicular to the length direction of the anchor rod 4. In this way, the anchor rod 4 will not fail due to insufficient pull-out resistance, and it can bear greater force. Each trailer 1 is equipped with at least two sets of anchor rods 4 and adjustable rope assemblies, such as two sets, four sets, six sets, etc., to form a symmetrical distribution structure and balance the force.
[0036] During actual construction, holes are drilled in the tunnel wall at the predetermined location (in front of the trailer), and anchor rods 4 are anchored to the tunnel wall. They are symmetrically arranged on both sides of the same cross section, with multiple anchor rods 4 corresponding to each trailer. When in use, the adjustable pull rope assembly is connected between the trailer and the anchor rod 4 to hold the trailer in place and lock the TBM dismantling trailer. This structure is simple, and multiple anchor rods 4 can be installed in the early stage of construction. When dismantling, the adjustable pull rope assembly can be installed.
[0037] In one embodiment, the adjustable rope assembly includes a hand chain hoist 5 and a wire rope 6 that are linearly connected, i.e., one end of the hand chain hoist 5 is connected to one end of the wire rope 6, and the two outer ends of the adjustable rope assembly are respectively connected to the anchor rod 4 and the trailer 1. Based on the adjustable length performance of the hand chain hoist 5, the length of the adjustable rope assembly can be adjusted at will to ensure the stable locking of the trailer 1.
[0038] In one embodiment, a trailer column 2 is fixedly installed on the trailer 1, and one end of the wire rope 6 is fixedly connected to the trailer column 2. The trailer column 2 provides a connection point for the connection of the wire rope 6, so that the trailer column 2 can stably connect the wire rope 6.
[0039] In one embodiment, each trailer 1 is equipped with four sets of anchor bolts 4 and adjustable rope assemblies. The four sets of anchor bolts 4 and adjustable rope assemblies are symmetrically distributed on both sides of the trailer 1 and symmetrically distributed at the four corners of the trailer 1 to ensure that the trailer 1 is securely locked.
[0040] In one embodiment, the anchor bolt 4 includes: an implantation part 401, a connecting part 402, a support block 403, and a transverse housing 405.
[0041] The implantation part 401 is fixed to the side of the implantation cavity wall 3. The connecting part 402 is integrally fixed to the end of the implantation part 401. The side of the connecting part 402 is provided with an elongated hole 402a and a round hole 402b. The elongated hole 402a is used to connect the adjustable pull rope assembly. The back of the transverse housing 405 is provided with a rectangular insertion hole. The transverse housing 405 is fixed to the side of the cavity wall 3 by expansion screws, and the connecting part 402 is located inside the rectangular insertion hole. A pin 404 is installed between the transverse housing 405 and the connecting part 402. The pin 404 is located inside the round hole 402b. The support block 403 is provided on the side of the connecting part 402 near the adjustable pull rope assembly. The support block 403 is located inside the transverse housing 405. The side of the support block 403 is provided with an inclined support surface corresponding to the side of the connecting part 402.
[0042] The transverse housing 405 and the connecting part 402 are connected together by a pin 404, and a support block 403 is designed to support the side of the connecting part 402. This structure prevents the connecting part 402 from deforming in the direction of tension when it is subjected to tension, thereby increasing the bending resistance of the connecting part 402. The design of the transverse housing 405 is also noteworthy.
[0043] In one embodiment, in order to increase the stability of the anchoring of the implant 401, an undercut 401a is provided on the side of the implant 401.
