[0023] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0024] like Figures 1 to 3 , Figure 5 As shown, this utility model provides a synchronous construction trolley, which includes a gantry mechanism 10. The gantry mechanism 10 includes four columns 12 and a top support frame 11 that connects the four columns 12. The top support frame 11 has a frame structure, and the four columns 12 are located at the four corners, forming a rectangular distribution.

[0025] The synchronous construction trolley also includes a base frame mechanism 20 and multiple support components 30. The base frame mechanism 20 includes two trolley base frames 21 arranged opposite each other, with a gap between them. The support components 30 are distributed at intervals along the length of the gap, and both ends of the support components 30 are detachably connected to the trolley base frames 21. Preferably, fasteners connect the support components 30 to the trolley base frames 21, forming a detachable connection. The support components 30 are detachably installed on the base frame mechanism 20, thereby maintaining high overall rigidity during the movement of the synchronous construction platform, and can be removed after transportation to the designated location.

[0026] The gantry mechanism 10 connects two trolley base frames 21, which are connected to the bottom of the columns 12 to form an integral structure. A through passage space 60 is formed between the trolley base frames 21 and the columns 12 of the gantry mechanism 10, and the support assembly 30 is located within the through passage space 60. The synchronous construction trolley is equipped with a through passage space 60, allowing vehicles to travel and be grouped within the installation area of ​​the synchronous construction trolley, thus achieving the effect of synchronous construction of the main tunnel and connecting passages. After the support assembly 30 is removed, the through passage space 60 can be left unobstructed.

[0027] like Figures 1 to 3 As shown, in one embodiment, the trolley base frame 21 includes a base frame body 211, a set of movable wheels 22 mounted on the base frame body 211, and a base support assembly 23. The base support assembly 23 is connected to the gantry mechanism 10, and the support assembly 30 is connected to the base frame body 211. The base frame body 211 is a rigid structural component, and the movable wheel set 22 is equipped with rubber wheels; alternatively, the movable wheel set 22 is equipped with rollers adapted to the movement of the guide rail, which can drive the synchronous construction trolley to move conveniently as a whole.

[0028] The base support assembly 23 is located at the bottom of the base frame body 211. The base support assembly 23 has a telescopic movement to raise or lower the base frame body 211. It can be used to adjust the height of the object carried by the base frame mechanism 20 when the synchronous construction trolley moves to the construction position, avoiding movement of the synchronous construction trolley and improving the convenience of height adjustment. The base support assembly 23 extends to the column 12, and the telescopic part can be set inside the column 12.

[0029] The passage space 60 of the synchronous construction trolley in this application allows for vehicle grouping during the construction of the main tunnel and connecting passages, thereby realizing the flow of materials. When the synchronous construction trolley is in initial commissioning or movement, the support component 30 helps to improve the overall strength and structural stability of the synchronous construction trolley.

[0030] Preferably, the support assembly 30 includes a crossbeam body 311 and connecting plates 312 located at both ends. The connecting plates 312 and the trolley base frame 21 are locked together by fasteners. The cross section of the connecting plate 312 is larger than that of the crossbeam body 311 to form a flange structure. The connecting plate 312 has multiple connecting holes, through which fasteners pass and are connected to the side of the trolley base frame 21.

[0031] Furthermore, the support components 30 located at both ends of the base frame mechanism 20 are fixed with traction seats 31. The traction seats 31 are used to connect traction equipment or to connect multiple synchronous construction trolleys in series. The traction seats 31 protrude from the surface of the crossbeam body 311 and are provided with through traction holes for connecting traction components to connect the synchronous construction trolleys for traction.

[0032] When the synchronous construction trolley is used as the starting trolley, it needs to be equipped with a sleeve device and a tunneling main unit. Correspondingly, the synchronous construction trolley also includes a shield support mechanism 40 detachably connected to the underframe mechanism 20, extending from one trolley underframe 21 towards another. The shield support mechanism 40 is used to support and adjust the sleeve device, allowing adjustment of its installation angle and height.

[0033] Optionally, the support assembly 30 includes an intermediate strut 32, and the shield support mechanism 40 is mounted on the intermediate strut 32 so that the intermediate strut 32 can provide support for the shield support mechanism 40. Optionally, the shield support mechanism 40 includes a base and a sliding part that slides on the base, the base being mounted on the intermediate strut 32 and the sliding part sliding on the base.

[0034] Optionally, the support assembly 30 includes an intermediate strut 32, with at least a portion of the shield support mechanism 40 sliding on the intermediate strut 32. The intermediate strut 32 supports the central region of the underframe mechanism 20 to enhance the overall strength of the underframe mechanism 20. Preferably, the shield support mechanism 40 is mounted on the underframe assembly, and the shield support mechanism 40 includes a sliding seat for supporting the sleeve device, which is slidably disposed on the intermediate strut 32.

[0035] like Figures 2 to 4 As shown, in one embodiment, the synchronous construction trolley further includes a reaction frame mechanism 50 installed on the gantry mechanism 10. The reaction frame mechanism 50 is located above one of the trolley underframes 21 and outside the passage space 60. The reaction frame mechanism 50 is installed on the gantry mechanism 10 and is arranged opposite to the sleeve device. The sleeve device and the reaction frame mechanism 50 are connected by a tie rod, and the reaction frame mechanism 50 can push the tunneling machine forward.

[0036] Preferably, the reaction frame mechanism 50 includes a rigid frame 51 and connecting frames 52 connected to both sides of the rigid frame 51. The connecting frames 52 are connected to the column 12. The column 12 is provided with an installation platform 121, and the connecting frames 52 are mounted on the installation platform 121, so that the rigid frame 51 is suspended in the air.

[0037] The synchronous construction trolley is also equipped with a control box assembly and other functional components. In one embodiment, the synchronous construction trolley further includes functional components mounted on the trolley base frame 21 and located outside the passageway 60. The functional components do not interfere with or obstruct vehicle formation and work in conjunction with the starting trolley to form a construction device.

[0038] A hoisting assembly 14 is installed on the starting trolley or part of the synchronous construction trolley. The hoisting assembly 14 is used to hoist items. The top support frame 11 is equipped with a single beam 13 and the hoisting assembly 14 slidably connected to the single beam 13. The length direction of the single beam 13 is parallel to the extension direction of the passage space 60. The single beam 13 is fixedly connected to the top support frame 11 and located in the top space of the passage space 60. The hoisting assembly 14 can slide along the single beam 13, thereby hoisting and moving items within the corresponding range of motion. These items include, but are not limited to, tunnel segments.

[0039] like Figure 3 and Figure 5 As shown, in one embodiment, the width of the passage space 60 is set as B, where 1.6 meters ≤ B ≤ 2.5 meters. The maximum carrying width of the vehicle group is less than the maximum width of the passage space 60. While ensuring that the space of the passage space 60 meets the passage requirements of the vehicle group, the passage space 60 is minimized to improve the structural strength of the underframe mechanism 20.

[0040] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. This application is intended to cover any variations, uses, or adaptations of the present invention that follow the general principles of this application and include common knowledge or customary technical means in the art that are not disclosed in this invention.
