Description

Technical Field

[0001] The invention relates to the technical field of shield machines, in particular to a negative ring-free construction ground frame and a reaction frame mechanism for a shield machine. Background Art

[0002] The shield machine reaction frame is a temporary support structure used in shield construction. Its main function is to provide reaction force at the starting stage of the shield machine to help the shield machine enter the stratum smoothly. When working, the shield machine reaction frame mechanism needs to be connected to the negative ring-free construction ground frame installed in advance in the working shaft, and the ground frame is used to provide stable bottom support. However, the connection operation between the existing reaction frame mechanism and the construction ground frame is not convenient enough, and the installation and disassembly of both will take a lot of time. In addition, the diagonal supports on the reaction frame lack a favorable support mechanism during installation, which makes it more troublesome to adjust its installation position, and thus makes the assembly efficiency poor and the work of the staff more difficult. Summary of the Invention

[0003] The purpose of the present invention is to provide a shield machine construction ground frame and reaction frame mechanism without negative ring, so as to solve the problems raised in the above background technology.

[0004] To achieve the above object, the present invention provides the following technical solutions: The shield machine reaction frame mechanism includes a reaction frame and diagonal support rods. The lower end of the reaction frame is fixedly provided with a support frame plate, and the reaction frame is positioned and supported by the support frame plate; The upper end of the diagonal support rod is connected to the reaction force carrier, and the lower end of the diagonal support rod is provided with a bottom fixing component, and the lower end of the diagonal support rod is fixed by the bottom fixing component.

[0005] Preferably, a frame stabilizing column is fixedly provided at the lower end of the support frame plate.

[0006] Preferably, the bottom fixing assembly includes a connecting ring and a safety lock pin, and the connecting ring is fixedly provided with a bottom lock column, and the lower end of the diagonal support rod is fixed by the bottom lock column; The safety lock pin fixes the connecting carrier ring to ensure its stability.

[0007] The shield machine's negative ring-free construction frame includes a frame body, the frame body is provided with a frame bearing hole, and the frame bearing hole cooperates with the frame body stabilizing column to realize the positioning of the reaction force bearing frame; Reaction frame fixing assemblies are respectively provided on both sides of the ground frame body, and the reaction frame is fixed by the reaction frame fixing assemblies; The reaction frame fixing assembly is connected to an auxiliary support assembly, the auxiliary support assembly is driven by the reaction frame fixing assembly, and the auxiliary support assembly cooperates with the diagonal support rod to support it; The ground frame body is also equipped with upper and lower synchronous support components, through which the upper and lower ends of the diagonal support rods are synchronously supported and fixed.

[0008] Preferably, the reaction frame fixing assembly includes a first hydraulic rod and a reaction frame fixing connecting plate, and the first hydraulic rod is fixedly connected to the reaction frame fixing connecting plate.

[0009] Preferably, the first hydraulic rod drives the reaction frame fixed connecting plate to move, so that the reaction frame fixed connecting plate cooperates with the reaction frame to fix the reaction frame.

[0010] Preferably, the auxiliary support assembly includes a driving support plate and a bearing arm plate, and the driving support plate is movably connected to the reaction frame fixed connecting plate.

[0011] Preferably, the driving support plate is movably connected to the bearing arm plate, driving the bearing arm plate to rotate, thereby achieving support for the diagonal support rod.

[0012] Preferably, the upper and lower end synchronous support components include a second hydraulic rod, a movable carrier, a connecting support rod and a diagonal support frame. The movable carrier is fixedly mounted on the second hydraulic rod, and the movable carrier is driven to move by the second hydraulic rod.

[0013] Preferably, the movable carrier cooperates with the bottom end of the diagonal support rod to support and fix the bottom end.

[0014] Preferably, the movable carrier is movably connected to a connecting rod, the upper end of the connecting rod is connected to a diagonal support frame, and the connecting rod drives the diagonal support frame to move, thereby realizing the connection between the upper end of the diagonal support rod and the reaction carrier.

[0015] Compared with the prior art, the present invention has the following advantages: 1. When assembling the base frame body and the reaction carrier, the position of the reaction carrier can be determined by the cooperation between the frame stabilizing column and the base frame bearing hole, which also plays a role in stabilizing the reaction carrier. Then, the first hydraulic rod can be activated to complete the fixed connection between the base frame body and the reaction carrier, thereby completing the fixation of the reaction carrier.

[0016] 2. The first hydraulic rod drives the reaction frame fixed connecting plate to move, so that the first fixed plug column and the second fixed plug column on the reaction frame fixed connecting plate cooperate with the reaction carrier to achieve stable installation of the reaction carrier. When the reaction frame fixed connecting plate moves, it will also drive the driving support plate to move, and then drive the bearing arm plate to rotate, providing favorable support for the subsequent installation of the diagonal support rod.

[0017] When the cam is in the upright position, the support rod is connected to the supporting arm plate, and the support rod disc and the supporting arm plate cooperate to support the supporting rod so that the upper end of the supporting rod is in the accurate installation position. Then the second hydraulic rod is started to drive the movable carrier to move, thereby driving the inclined support base to move. With the action of the inclined support base, the inclined surface of the inclined support base will contact the bottom locking column, and then, under the action of the inclined surface, the bottom locking column will be pushed to move until the bottom locking column is aligned with the connecting lock path. At this time, the bottom support plate of the rod is in contact with the inclined support base, and the bottom locking column is inserted into the interlocking lock path to achieve the fixed support of the lower end of the diagonal support rod. In addition, when the movable carrier moves, it will also drive the diagonal support frame to move, thereby connecting the diagonal support rod on the diagonal support frame to the connecting plate frame and the diagonal support connecting plate to achieve the fixation of its upper end, making the installation of the diagonal support rod more convenient and quick, and the carrying arm plate can play an auxiliary supporting role for it during later use, making the entire reaction frame mechanism more stable and reliable.
