Platform space-consuming is big, and when running into vehicle track running, it avoids not aspect, not only influences the operation of railcar, while have an effect on and apply
Work.
For constructing tunnel These characteristics, in order to improve efficiency of construction, the influence that crossed construction is brought is reduced, research is a kind of
Detachable adjustable for height subway tunnel section construction operation platform, it appears particularly important.
Utility model content：
The defects of the utility model purpose is exactly to make up prior art, there is provided one kind is detachable adjustable for heightly
Iron transit tunnel construction operation platform, ensureing that platform is firm and on the premise of meeting load-bearing requirements, alleviating operating platform
Weight, the difficulty that platform is transported to Gui Hang areas is reduced, while height adjustable allows it to deal with different construction requirements.
The utility model is achieved through the following technical solutions：
A kind of detachable adjustable for height subway tunnel section construction operation platform, it is characterised in that：Include two-phase
The platform structure part of mutual corresponding matching, the bar that is detachably connected being spaced apart is installed between the two platform structures part, it is described
Platform structure part includes cat ladder handrail and operating platform guardrail, and tunnel is provided with the front edge of the operating platform guardrail
Wall pulley assembly, the bottom of the platform cat ladder are provided with lightweight track wheel assembly, and the rear of the platform cat ladder is provided with platform
Support bar, the upper end of the table support bar are arranged in the connecting rod in the middle part of platform cat ladder by bearing pin, the platform
The lower end of bar is provided with movable pulley.
Described tunnel wall pulley assembly component includes fixed beam, and the fixed beam is fixedly mounted on operating platform guardrail
Front edge at, the both ends of the fixed beam are provided with tunnel wall pulley by anti-slip device respectively.
Described lightweight track wheel assembly includes bottom girder, and the bottom girder both ends are provided with and platform cat ladder bottom vertical bar
The sleeve pipe coordinated is set with, the pin hole fixed by latch is distributed with the platform cat ladder bottom vertical bar and sleeve pipe respectively,
The both ends of the bottom girder are provided with lightweight rail wheel by anti-slip device respectively.
Adjusting rod is provided between the lower end of described table support bar and movable pulley, the movable pulley is fixed on adjusting rod
Bottom, adjusting rod and table support bar the bottom suit coordinates, and the positioning hole fixed by latch is distributed with respectively.
In long distance tunnel, above-mentioned platform can steadily move on rail, and support bar is using with operating desk cat ladder
When form the rock-steady structure of triangle, substantially increase the stability of operating platform, while the design of packaged type also carries significantly
High constructing tunnel efficiency.Its material is being ensured that platform is firm and is being met the premise of load-bearing requirements using conventional coating steel pipe
Under, the weight of operating platform is alleviated, reduces the difficulty that platform is transported to Gui Hang areas.Using lightweight pulley as track guide wheel,
Slip damping of the pulley when being run on rail is greatly reduced, effectively raises the mobile efficiency of platform.
The utility model has the advantages that：
The utility model is designed using detachable, folding, adjustable height, runs into railcar in constructing tunnel
During by needing to avoid, operating platform can be dismantled；Whole dismounting process used time about 2 minutes during operation, and dismantle and complete
Afterwards, each component space-consuming is smaller, avoids component after having dismantled from invading limit, causes the accident.
Brief description of the drawings：
Fig. 1 is overall structure figure of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is front view of the present utility model.
Fig. 4 is configuration schematic diagram of the present utility model.
Embodiment：
Referring to accompanying drawing.
A kind of detachable, collapsible, adjustable for height subway tunnel section construction operation platform, including be horizontally placed on rail
Side is for mobile lightweight rail wheel (containing anti-slip device) 1, the platform structure part 9 comprising operating platform guardrail 6 and cat ladder handrail 8,
Connected between the platform structure part by connecting rod 11, the platform branch comprising table support bar 3 and movable pulley (containing anti-slip device) 2
Strut 10, it is placed in the platform for being used for mobile tunnel wall pulley 5 on shield tunnel wall and being completed using coating steel pipe and climbs
Ladder 4 and operating platform 7.
The tunnel wall pulley 5 is arranged on the both ends of fixed beam 12, and the fixed beam 12 is fixedly mounted on operating platform shield
At the front edge on column.
The lightweight rail wheel 1 is arranged on the both ends of bottom girder 13, and the both ends of bottom girder 13 are provided with and platform cat ladder bottom
Vertical bar is set with the sleeve pipe 14 coordinated, is distributed with the platform cat ladder bottom vertical bar and sleeve pipe 14 and is fixed by latch respectively
Pin hole.
