Technical Field

[0001] The invention relates to the technical field of shield machines, in particular to a preset track bracket in a negative ring-free reverse pulling device of a shield machine. Background Art

[0002] When the shield machine is performing negative ring-free reverse pull launching, it is necessary to preset a track bracket in the working shaft to provide strong support for the shield machine during launching, so as to ensure the smooth launching of the shield machine. The preset track bracket needs to be equipped with a support plate to stably support the shield machine through the support plate. The existing track bracket needs to be fixed to the track bracket one by one by bolts when installing the support plates. Although the traditional bolt fixing method can ensure the firmness of the support plate installation, due to the large number of support plates, each support plate requires multiple bolts to tighten it, so each support plate will take a lot of time to install, which makes the installation efficiency of the support plate relatively low. In addition, it also takes a lot of time to dismantle the support plate in the later stage, which cannot achieve the convenient installation and removal of the support plate and improve its installation efficiency. Summary of the Invention

[0003] The object of the present invention is to provide a preset track bracket in a negative ring-free reverse pulling device of a shield machine, so as to solve the problems raised in the above background technology.

[0005] Preferably, a lower supporting boss is fixedly provided at the lower end of the supporting plate, and a plug-in mounting platform is fixedly provided at the lower end of the lower supporting boss; A movable built-in cavity is provided on the plug-in mounting platform, and the movable built-in cavity extends into the lower supporting boss.

[0006] Preferably, a mounting inner cavity is provided on the support rail, and the mounting platform is inserted into the mounting inner cavity when the support bracket is installed on the support rail.

[0007] Preferably, the support plate connection assembly includes an inward movable bar and a movable loading plate, and the inward movable bar is two and symmetrically installed in the movable built-in cavity.

[0008] Preferably, the inwardly movable bar is connected to a movable supporting plate, and the movable supporting plate is also located in the movable built-in cavity.

[0009] Preferably, the support plate is fixed by the cooperation between the movable loading plate and the support rail.

[0010] Preferably, the support plate connection reinforcement assembly includes a rotating operating disk and a load-bearing lock plate, and a safety lock rod is installed on the rotating operating disk, and the safety lock rod can lock the rotating operating disk.

[0011] Preferably, a linkage support plate is installed on the rotary operating disk, and the linkage support plate is movably connected to the bearing lock plate.

[0012] Preferably, a load-bearing locking bar is fixedly provided on the load-bearing locking plate, and the load-bearing locking bar cooperates with the supporting plate to fix the supporting plate.

[0013] Preferably, the load-bearing locking bar cooperates with the inwardly moving movable bar to drive the inwardly moving movable bar to move when moving.

[0014] Preferably, the auxiliary fixing component is a loading connecting block, and the load-bearing locking plate drives the loading connecting block to move and cooperate with the supporting plate to auxiliary fix it.

[0015] Compared with the prior art, the present invention has the following advantages: 1.

[0016] 2. When the rotary operating disk rotates, it will drive the load-bearing lock plate to move, so that the load-bearing lock bar on the load-bearing lock plate is inserted into the installation matching channel on the support tray. The initial fixation of the support tray is achieved through the cooperation of the load-bearing lock bar and the installation matching channel. As the load-bearing lock bar is inserted into the installation matching channel, it will push the inward movable bar to move. As the inward movable bar moves, it will drive the movable loading plate to move under the action of the first movable loading rod, so that the loading column on the movable loading plate is inserted into the connecting inner bearing hole, thereby further fixing the support tray.

[0017] 3. In addition, when the load-bearing lock plate moves, it will also drive the loading connecting block to move, so that the reinforced plug-in column on the loading connecting block is inserted into the mounting reinforcement hole on the support tray, which plays an auxiliary fixing role for the support tray, fully ensuring the firmness of the support tray installation, and the rotating operating disk can be locked after the support tray is firmly installed after moving, ensuring that it will not rotate erroneously under the action of external force, thereby ensuring the stability of the support tray installation.

As the inward movable bar 3 moves, the movable loading plate 4 will be pushed to move under the action of the first movable loading rod 36. As the movable loading plate 4 moves, the loading column 42 on the movable loading plate 4 will move, and then the loading column 42 will be inserted into the connecting inner bearing hole 14 on the support rail 12. The support bracket 2 can be further fixed by the cooperation of the loading column 42 and the connecting inner bearing hole 14. In addition, the load locking plate 6 will also drive the connecting matching plate 65 to move during the movement. As the connecting matching plate 65 moves, the pulling channel 66 and the pulling matching column 72 on the loading connecting block 7 will drive the loading connecting block 7 to move, thereby making the reinforcing plug-in column on the loading connecting block 7 71 is inserted into the installation reinforcement hole 24 on the support bracket 2, which realizes auxiliary fixation of the support bracket 2, fully ensuring the firmness of the installation of the support bracket 2, and can quickly install the support bracket 2, greatly improving the work efficiency of the installation of the support bracket 2, and facilitating the installation work of the staff. When the track bracket body 1 is used up and needs to be disassembled, the operating carrier 54 is pulled to make the safety lock rod 53 exit the lock position through hole 191 on the lock lower convex plate 19, so that the rotary operating disk 5 is in the unlocked state, and then the rotary operating disk 5 is rotated in the reverse direction to move it in the direction of the support rail 12 under the action of the thread, so that the linkage carrier plate 58 can be driven to move in the direction of the support rail 12.The second movable stowage rod 591 is engaged with the locking plate 6 and the locking bar 63 of the locking plate 6 to move in the opposite direction, so that the locking bar 63 on the locking plate 6 is withdrawn from the installation matching channel 26, so that the locking bar 63 no longer plays a role in fixing the support plate 2.
