The utility model has the advantages of scientific, reasonable and creative design, compact integral structure, low cost, simple operation, stable and reliable performance, strong practicability, quite reliable safety guaranteeing step and good development prospect, and can be connected scientifically with a computer, a monitor, an image pick-up device and a range radar, as well as can actualize the intelligentizing operation management through the operation of a software. The utility model is applicable to tunnel construction.

Description

A kind of tunnel inverted arch sliding form apparatus

Technical field

The utility model relates to a kind of sliding form apparatus, what concrete was with the construction of what tunnel inverted arch can move ahead, retreat two-way mobile sliding form apparatus.

Background technology

Along with the development that building trade is advanced by leaps and bounds, also extensive ruly the carrying out of the ancillary facility of subterranean tunnel.In the water-conveyance tunnel construction, the limit crown of the lining concrete first half and the inverted arch of Lower Half need some plant equipment to finish when building, and be used for the mostly employing sliding formwork of subterranean tunnel inverted arch construction, the pattern of sliding formwork is varied, specification is various, plays indispensable effect in building operations.Yet the sliding formwork that uses can move ahead by pulling wire rope at present, no matter the mode that pulls is to adopt machinery or manually all more or less exist the not high problem of efficient, especially this move mode of sliding formwork can only move ahead, and can not retreat, can not retreat immediately when other problem such as local quality having occurred when inverted arch, this is exactly a kind of big problem of especially paying close attention to of being worth concerning the assurance of workmanship.

Just exist the problem that these can not be ignored because of used sliding formwork, and in construction, do not have corresponding safeguard measure and method, and can only when tunnel construction, inject manpower more, slow down the quality that speed is tried to achieve construction, thereby the reduction of the efficient of whole construction, construction cost increases greatly.

Summary of the invention

The purpose of this utility model is easily to cause the problem of construction and provide a kind of energy two-way mobile a kind of tunnel inverted arch sliding form apparatus for the sliding formwork that solves present use can only unidirectionally move.

The technical scheme that adopts is:

A kind of tunnel inverted arch sliding form apparatus comprises the sliding formwork frame, a plurality of pulleys, a plurality of sprocket wheel, chain, motor; The bottom surface of sliding formwork frame is arranged to matrix (fitting like a glove with the design profile size) shiny surface, and a plurality of pulley symmetries are installed in the lower end of sliding formwork frame both sides; Its design feature is:

What described a plurality of sprocket wheel was corresponding respectively fixedlys connected with a plurality of pulleys, and a plurality of pulleys and sliding formwork frame are rotationally connected; A plurality of motors be installed in symmetrically sliding formwork frame both sides above, be connected with a plurality of sprocket rotation that are fixed on the pulley of homonymy by chain; A plurality of sprocket wheels of homonymy are rotationally connected mutually by chain.

Operating principle:

Pulley of the present utility model is positioned on the reservation platform of both sides below the limit crown of building moulding (it is identical with the design profile line to reserve table top), when just changeing, motor makes sprocket rotation by chain, the rotating band movable pulley of sprocket wheel moves ahead along reserving platform, and the smooth bottom surface of sliding formwork matrix is scraped concrete and is pressed into inverted arch.When construction was pinpointed the problems, changeover switch made the motor counter-rotating, and at this moment sliding formwork integral body is retired, thereby reaches the forward and reverse driving of sliding formwork purpose freely.

The utility model design science, reasonable, original, compact overall structure, with low cost, simple to operate, stable performance, reliable, practicality is stronger, the safety assurance link is extremely reliable, has development prospect preferably, can with the linking together of computer, monitor, image pick-up device, range radar science, implement the intellectualized operation management by the operation of software, use in the suitable tunnel construction of the utility model.
