Detailed Implementation

[0022] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0023] Example 1 refer to Figure 1 As shown, a tunneling machine starting bracket includes a left bracket 1, a right bracket 2, an alignment reinforcing beam 3, a left buffer rod 4, a right buffer rod 5, and a transition connecting plate 6.

[0024] The left bracket 1 and right bracket 2 are detachably assembled, allowing for quick and direct assembly to initially position and connect them. This detachable assembly method enables the brackets to be flexibly assembled and disassembled according to actual construction needs, facilitating transportation and on-site installation.

[0025] A aligning reinforcing beam 3 connects the left bracket 1 and the right bracket 2. This beam indirectly connects the two brackets, strengthening and fixing them to form a unified bracket structure. The aligning reinforcing beam 3 not only enhances the overall structural strength of the bracket but also facilitates its positioning and installation.

[0026] The alignment and reinforcing beam 3 is equipped with a lifting caster assembly. When the bracket needs to be moved, the caster assembly is lowered to the ground. The caster assembly can be used to push the bracket, making it easy to move the bracket. When the bracket is normally supported, the caster assembly is raised without affecting the bracket's placement on the ground.

[0027] The left bracket 1 is equipped with a left buffer rod 4 that is inclined to the right, and the right bracket 2 is equipped with a right buffer rod 5 that is inclined to the left. The left buffer rod 4 and the right buffer rod 5 together form an inward support structure to buffer and support the tunneling machine and avoid excessive impact force from the tunneling machine on the bracket.

[0028] The left bracket 1 and the right bracket 2 are arranged symmetrically to ensure the symmetry and similarity of the left and right structures, thereby balancing the forces on both sides and facilitating the manufacturing of the brackets. The left buffer rod 4 and the right buffer rod 5 are also arranged symmetrically to ensure balanced forces on both sides.

[0029] The left bracket 1 and the right bracket 2 are an integral structure welded from structural steel. The left bracket 1 includes a left longitudinal beam 11, a left transverse beam 12, and a left auxiliary reinforcing beam 13. The right bracket 2 includes a right longitudinal beam 21, a right transverse beam 22, and a right auxiliary reinforcing beam 23. Several left transverse beams 12, spaced apart along the longitudinal direction, are fixedly connected to the right side of the left longitudinal beam 11. Left auxiliary reinforcing beams 13 are fixedly connected between the left transverse beams 12 to form a frame-like left bracket 1. Several right transverse beams 22, spaced apart along the longitudinal direction, are fixedly connected to the left side of the right longitudinal beam 21. Right auxiliary reinforcing beams 23 are fixedly connected between the right transverse beams 22 to form a frame-like right bracket 2.

[0030] A positioning reinforcement beam 3 connects the left longitudinal beam 11 and the right longitudinal beam 21. Specifically, the left longitudinal beam 11 has a vertically penetrating left positioning hole 110, and the right longitudinal beam 21 has a vertically penetrating right positioning hole 210. The left and right ends of the positioning reinforcement beam 3 have vertically penetrating left connecting holes 301 and right connecting holes 302, respectively. The left positioning hole 110 and the left connecting hole 301, and the right positioning hole 210 and the right connecting hole 302 are connected by studs. This positioning connection structure allows the positioning reinforcement beam 3 to be accurately installed on the left longitudinal beam 11 and the right longitudinal beam 21, ensuring the overall positioning accuracy of the bracket.

[0031] The right end of the left transverse beam 12 is detachably connected to the left end of the right transverse beam 22. Specifically, a detachable transition connecting plate 6 is connected between the left bracket 1 and the right bracket 2. The transition connecting plate 6 is made of rectangular steel plate, which is directly attached to the end face of the transverse beam and fixedly connected to the transverse beam by bolts.

[0032] At least two alignment reinforcement beams 3 are provided to ensure the stability of the connection between the left and right brackets and to provide sufficient mounting points for the caster wheel assembly. The ends of the alignment reinforcement beams 3 that extend relative to the brackets are equipped with lifting caster wheel assemblies. This extension design provides sufficient space for installing the left caster wheel 31 and the right caster wheel 32, while also increasing the stability of the bracket during movement. The lifting function of the caster wheel assembly allows the bracket to be lowered when needed, enabling flexible movement; and raised after the bracket is positioned and installed, preventing the caster wheels from affecting the stability of the bracket.

[0033] The caster wheel assembly consists of a left caster wheel 31 and a right caster wheel 32. The left end of the alignment reinforcing beam 3 is connected to the lower left caster wheel 31 via a left lifting rod 33, and the right end of the alignment reinforcing beam 3 is connected to the lower right caster wheel 32 via a right lifting rod 34. The left lifting rod 33 and right lifting rod 34 are preferably hydraulic cylinders, allowing for convenient control of the raising and lowering of the left caster wheel 31 and right caster wheel 32, making operation simple and convenient.

[0034] The left buffer rod 4 is mounted on the left auxiliary reinforcing beam 13, and the right buffer rod 5 is mounted on the right auxiliary reinforcing beam 23. The placement of the left and right auxiliary reinforcing beams 13 and 23 further enhances the structural strength of the bracket and improves its load-bearing capacity. Simultaneously, the left and right auxiliary reinforcing beams provide a foundation for the placement of the buffer rods. The left buffer rod 4 and right buffer rod 5 are damping buffers or spring buffers, which can play a buffering role during the initial operation of the tunneling machine, reducing the impact force of the tunneling machine on the bracket and extending the service life of the bracket.

[0035] The workflow of this application is as follows: I. Assembly Process: 1. First, transport the left and right brackets to the construction site separately. The left bracket consists of a left longitudinal beam and multiple left transverse beams, and the right bracket consists of a right longitudinal beam and multiple right transverse beams. 2. Splice the left and right transverse beams to initially connect the left and right brackets together. 3. Place the alignment reinforcement beam on top of the left and right longitudinal beams, aligning the left connecting hole with the left positioning hole vertically, and the right connecting hole with the right positioning hole vertically. Then, connect and fix the alignment reinforcement beam to the left and right longitudinal beams using bolts. 4. Install the left lifting rod and left swivel caster on the left end of the alignment reinforcement beam, and install the right lifting rod and right swivel caster on the right end.

[0036] II. Moving process: When it is necessary to move the bracket, operate the left and right lifting levers to lower the left and right swivel wheels, so that the bracket is lifted off the ground and supported by the swivel wheels. Then the bracket can be easily pushed to the designated position.

[0037] III. Positioning and Installation Process: After the bracket is moved to the designated position, raise the left and right casters by operating the left and right lifting rods to place the bracket stably on the ground. Check the positioning of the bracket again to ensure that it meets the construction requirements.

[0038] IV. Usage: During the initial launch of the tunneling machine, the left and right buffer bars act as a buffer, reducing the impact of the tunneling machine on the support frame and protecting the frame structure. Simultaneously, due to the high structural strength and precise positioning of the support frame, it provides stable and reliable support for the tunneling machine's launch, ensuring the normal operation of the tunneling machine and the quality of construction.

In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.
