The utility model discloses process simple and convenient, safe in utilization, reliable, can greatly reduced the snubber construction degree of difficulty, guarantee snubber construction quality, the expense is low, saves the engineering time, does not occupy unnecessary tunnel construction space.
Description
Technical field
The utility model is tunnel hydraulic pressure demolition snubber construction assistance platform, belongs to tunnel snubber technical field of construction.
Background technology
At present, snubber construction in tunnel adopts the construction of excavation chassis, when ensureing to slag tap vehicle pass-through, in the middle of chassis, cannot operation platform be set, for the larger tunnel of section, middle cut eye construction comparatively difficulty, and snubber angle and branch cannot be ensured evenly, affect hydraulic pressure demolition effect.If separately add a small-sized chassis, increase expense and strengthen, and take constructing tunnel space.
Summary of the invention
In order to overcome a large-span tunnel snubber construction technology difficult problem, the utility model proposes one on original chassis, set up snubber construction assistance platform, this platform reduces large-span tunnel snubber difficulty of construction, and can well ensure snubber construction quality.It is low that this construction assistance platform has cost, and processing is simple, easy-to-use, and does not take the advantages such as constructing tunnel space.
For achieving the above object, the technical solution adopted in the utility model is hydraulic pressure demolition snubber construction assistance platform, this platform is divided into symmetrical two panels, and every sheet platform comprises Chain block 2, platform reinforced mesh 4, platform docking sleeve pipe 6, rotary hinge 7, channel-section steel stiffening rib 8; Chassis crossbeam 1, diagonal brace 3, chassis longeron 5 are former trolley structure, and chassis crossbeam 1, chassis longeron 5 mutually square crossing arrange the braced structures of composition chassis; Diagonal brace 3 is arranged on braced structures side, and diagonal brace 3 is welded between the chassis crossbeam 1 of braced structures, chassis longeron 5; Each channel-section steel stiffening rib 8 is parallel to each other and is arranged on the chassis crossbeam 1 of former trolley structure by rotary hinge 7, channel-section steel stiffening rib 8 is welded with platform reinforced mesh 4; Each channel-section steel stiffening rib 8 forms half work plane with platform reinforced mesh 4; Symmetrical two panels work plane forms the work plane of this construction assistance platform; The platform docking sleeve pipe 6 be welded with respectively bottom the channel-section steel stiffening rib 8 of each half work plane joint on platform docking sleeve pipe 6, two work plane is symmetrical, is located by connecting by half work plane by inserting reinforcing bar in platform docking sleeve pipe 6.
The braced structures top of chassis is provided with Chain block 2, and Chain block 2 is connected with platform reinforced mesh 4 by wire rope; When needs are constructed, control Chain block 2 and unclamp platform reinforced mesh 4; When construction completes, control Chain block 2 pull-up platform reinforced mesh 4 to diagonal brace 3 place and fix.
The beneficial effects of the utility model are, device processing is simple and convenient, use safety, reliable, and can greatly reduce snubber difficulty of construction, ensure snubber construction quality, expense is low, saves the engineering time, does not take unnecessary constructing tunnel space.This structure is applicable to the engineering of large-span tunnel snubber construction, facilitates Long span tunnel snubber to construct, and improves the Angle ambiguity in snubber work progress, ensures that snubber is arranged evenly simultaneously, improves hydraulic pressure demolition whole structure.

Detailed description of the invention
As Figure 1-5, hydraulic pressure demolition snubber construction assistance platform, it utilizes existing excavation chassis, and chassis increases operation platform; Docked with chassis longeron 5 by rotary hinge 7, platform divides left and right two panels, is completed the folding and unfolding operation of platform by Chain block 2.Assistance platform size is according to the processing of excavation chassis real size.During snubber construction, platform is put down and knows level, constructor stands on this platform and completes snubber construction operation, after having constructed, utilize Chain block to be packed up by platform, and be fixed on the diagonal brace of chassis, do not affect drag-out slag car and run, platform puts down when using by snubber again, so recycles.Land lengths is determined according to the horizontal clear distance of chassis, guarantees left and right two platform docking.
Concrete operations flow process is as follows,
S1 on request size prepares three channel-section steel longerons, and specification is No. 12 channel-section steels.
S2 adopts rotary hinge to be docked with chassis longeron by channel-section steel longeron, and rotary hinge is fixed on chassis longeron, arranges according to shown in figure bis-.
S3 adopts diameter 10mm screw-thread steel platform for making, and screwed pipe transverse and longitudinal spacing is 10cm together, specifically as shown in Figure 3.
S4 utilizes the Chain block be fixed on chassis head piece that platform is placed level, and is docked by platform, sees shown in Fig. 1 and Fig. 2.
S5 constructor stands on platform and carries out snubber construction.
After S6 snubber has been constructed, Chain block is utilized to be packed up by platform, as shown in Figure 1.
S7 repeats S4-S6, recycles platform.
