Technical field

The present invention relates to railway Construction Formwork & Scaffold Technology fields, and in particular to a kind of scaffold for railway tunnel maintenance.

Background technique

In order to eliminate railway tunnel disease, guarantee train operating safety, it is often necessary to which maintenance and repair are carried out to tunnel.Tunnel Road disease mainly has limit deficiency, lining cracking, leak and pollution etc..

Need to use scaffold when conserving railway tunnel, scaffold refers to that construction site is worker operation and solves The various brackets for vertically and horizontally transporting and setting up.Mainly for construction personnel works or perimeter security net is gone along with sb. to guard him and high-altitude up and down The making material of installation component etc., scaffold usually has: bamboo and wood, steel pipe or synthetic material etc..

Current scaffolding structure is simple, can only use on level land, and the ground of railway tunnel is usually laid with many stones Head, ground out-of-flatness are difficult to set up scaffold and guarantee the stability of scaffold；In addition, since worker usually needs to railway Tunnel carries out comprehensive inspection and maintenance, so the position of frequent movable Scaffold on the ground is needed, simultaneously because tunnel is cut Face is arc, and worker is to the height for usually needing to adjust scaffold at the top of tunnel when conserving, and current scaffold exists Displacement and height adjustment aspect are very complicated, it is often necessary to waste the excessive time and efforts of worker.

Summary of the invention

Based on problem above, the present invention provides one kind and is easily assembled to, dismantles and shifts, and is easy to adjust the position of horizontal direction With the height of vertical direction, the tunnel bigger suitable for width matches with the cross sectional shape in tunnel, can reduce assembling time Number saves the scaffold for railway tunnel maintenance of the time and efforts of worker.

In order to solve the above technical problems, the present invention provides following technical schemes:

The top of a kind of scaffold for railway tunnel maintenance, including rail idler wheel, the rail idler wheel is equipped with level It is arranged and perpendicular to the sliding rail of rail, the quantity of the sliding rail is two and Parallel Symmetric is arranged；The both ends of the sliding rail are all provided with There is connection rail, the connection rail is detachably connected with sliding rail, and the bottom of the connection rail is equipped with telescopic supporting leg；The cunning The top of rail is equipped with slideway, and bar shaped sliding block is equipped in the slideway, and the top of the sliding block is equipped with across the top of two sliding rails Support plate；Two rows of fixing seats are symmetrically arranged at the top of the support plate, two rows of fixing seats are respectively arranged on two sliding rails Surface, the center of the fixing seat are equipped with fixing groove, are equipped with the fixed link being threadedly coupled with fixing groove, institute in the fixing groove Stating fixed link includes isometric bottom bar and extension rod, and link slot one, the extension are equipped at the top of the bottom bar and extension rod The bottom of bar is equipped with the insertion bar one chimeric with the link slot one of bottom bar, and the side wall on the top of the bottom bar and extension rod is equipped with Block, the bottom bar are equipped with the fixation being threadedly coupled with the side wall of bottom bar and extension rod with the side wall of the junction of extension rod Cylinder, the bottom of the fixed cylinder is abutted with block；The height of fixed link described in every row is successively decreased in gradient, described in both ends The side wall of extension rod between fixed link is equipped with supporting block, and the supporting block is consolidated towards height is lower than the fixed link where it The top of the supporting block of fixed pole, the fixed link and fixed link adjacent thereto is equipped with horizontally disposed platen, the platen Bottom is equipped with the insertion bar three in the link slot one at the top of insertion extension rod；In two rows of fixed links minimum fixed link it Between be equipped with and trample bar with what fixed link was detachably connected, the outer wall of bottom bar described in every row and extension rod is equipped with adjacent fixation The connecting rod of bar connection, the connecting rod are detachably connected with fixed link.

Further, the end that the both ends of the sliding rail and connection rail deviate from sliding rail is equipped with link slot two, the connection The end that rail is connected with sliding rail is equipped with the insertion bar two chimeric with the link slot two of sliding rail, the junction of the connection rail and sliding rail Outer wall be equipped with connection strap, the both ends of the connection strap are connected with the outer wall for connect rail and sliding rail respectively, the connection strap and company It integrates with and is equipped with bolt between sliding rail；Convenient for assembling, disassembly and transhipment, connection rail can be increased or decreased according to tunnel width Quantity makes the present apparatus be suitable for the tunnel of different in width.

Further, the cross section of the supporting leg is rectangular, and the supporting leg includes the first support column and the second support Column, the bottom of first support column be equipped with chimeric column, and the top of second support column is equipped with to be screwed on chimeric male screw Embeded slot；It is finely adjusted convenient for the height to supporting leg, so that sliding rail be made to be in horizontal plane, guarantees operational security.

Further, the bottom end of second support column is equipped with the rubber sleeve for wrapping up the bottom end of the second support column, described Rubber sleeve is equipped with card convex towards the inner wall of the second support column, and second support column is equipped with the card slot engaged with card convex；Facilitate branch Support leg is steadily contacted with the ground of railway tunnel.

Further, side wall of the minimum fixed link away from the side where highest fixed link is equipped with fixture block, institute Fixture block is stated equipped with the bayonet towards the side where the center of support plate, the both ends for trampling bar are caught in bayonet；Convenient for group Dress, disassembly and transhipment.

Further, the connecting rod is obliquely installed, the line and connecting rod positioned at the top of the fixed link at both ends In parallel, bolt is equipped between the connecting rod and fixed link；The stability for improving whole device improves present apparatus eminence work Safety when industry.

Compared with prior art, the beneficial effects of the present invention are: the present invention is convenient for assembling, disassembly and transhipment, high altitude operation Stability it is good and safety, be easy to adjust the position of horizontal direction when operation and the height of vertical direction, be suitable for different width The cross sectional shape in the tunnel of degree, top and tunnel matches, and sets up an operation that the present apparatus can complete wide area, Compared with prior art, reduce scaffold sets up number, saves activity duration and the energy of staff.
