Description
Technical field
The present invention relates to a kind of tunnel construction trolley, the constructing tunnel cantilever platform of specifically a kind of automatically retractable platform
Car, belongs to road and bridge construction field.
Background technology
The energy-saving and emission-reduction proposed in national basis build fast development, environmental protection construction ground theory, while mitigating constructor
The labour intensity of member.Construction trolley is needed to use in tunnel excavation construction, the fixed excavation construction chassis for now using, fixed
Job platform is mainly used in excavation, supporting, aids in the work such as stand, and stand work is transported mainly by loading machine, lifted, manually lift, draw,
Drag, prize to complete, construction trolley is typically pushed into excavation face with loading machine, due to bottom surface contact after each Excavation blasting
Will be prominent tens centimeters, and whole section is slope, workmen is had a segment distance, construction apart from chapelet face rock
Chassis in place when also need to set up seesaw again and press close to rock, be easy to workmen to beat its of air pressure gun drilling blasting charge and chapelet face
It constructs；There is a method in which be exactly to fry by the prominent rock explosive in bottom again after quarrel, while also needing to excavation
Machine is pulled away the rock cleaning fallen is fried, and relative work intensity is big, installs lack of standardization, effect low；The engineering time so is wasted,
Air in fried rock and mucking and serious dirt beam tunnel, also increases construction cost.
The content of the invention
The purpose of the present invention is to overcome defect at present existing for fixed excavation construction chassis, so that open one kind can be automatic
The constructing tunnel cantilever chassis of scaling platform.
Technical scheme is as follows：
One group of movable pulley is respectively installed in the termination of two foundation soffits, it is equidistant above two foundation beams to fix several door frames,
Skid beam is fixed respectively in all door frame both upper ends thereofs, it is tangent respectively on skid beam to be provided with movable pulley, the hinge difference of movable pulley
Fixed with mobile platform above, mobile platform is connected support separately below, and fixed support side is provided with support wheel and puts
In in the groove of skid beam, fixed hydraulic oil cylinder is distinguished in inner side above door frame at one end, and the telescopic end of hydraulic jack is hinged at movement
The bottom surface of platform, lays platform mesh sheet above mobile platform, the two ends of mobile platform are provided with guard rail, pacifies on bottom girder
Dress hydraulic control box.
It is characteristic of the invention that construction trolley top surface be provided with a mobile platform can automatic telescopic forward or backward,
And extension elongation can arbitrarily control to reach the specified location of construction, that is, the width of distance construction scar is reached, due to applying
Work platform can voluntarily move forward, and freely stretch, thus it is simple and efficient to handle, human resources are saved, reduce the air in tunnel
Pollution.Simultaneously will not shadow to other working procedures, reduce construction cost, improve operating efficiency, be a kind of preferable tunnel
Road construction cantilever chassis.
Brief description of the drawings
Accompanying drawing 1 is main structure diagram of the invention.
Accompanying drawing 2 is left view structural representation of the invention.
Accompanying drawing 3 is the A-A section structure schematic diagrames of accompanying drawing of the present invention 1.
Reference title is as follows：Road wheel 1, bottom girder 2, door frame 3, skid beam 4, movable pulley 5, support wheel 6, fixed support 7,
Mobile platform 8, hydraulic jack 9, guard rail 10, platform mesh sheet 11, hydraulic control box 12.
Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing：
One group of movable pulley 1 is respectively installed in the termination of the bottom surface of two foundation beam 2, it is equidistant above two foundation beams 2 to fix three door frames
3, skid beam 4 is fixed respectively in the both upper ends thereof of all door frames 3, it is tangent respectively on skid beam 4 to be provided with movable pulley 5, the hinge of movable pulley 5
Axle is fixed with mobile platform 8 above respectively, and mobile platform 8 is connected support 7 separately below, and the side of fixed support 7 is provided with
Support wheel 6 and it is placed in the groove of skid beam 4, at one end the inner side fixed hydraulic oil cylinder 9 respectively above of door frame 3, hydraulic jack 9 is stretched
Contracting end is hinged at the bottom surface of mobile platform 8, and platform mesh sheet 11 is laid above mobile platform 8, and the two ends of mobile platform 8 are provided with anti-
Guard rail rod 10, in the hydraulic control box 12 installed above of bottom girder 2.
Construction trolley is first pushed into face during present invention work, starting hydraulic control motor stretches out hydraulic jack, together
When support wheel and movable pulley rotate drive mobile platform forward extend out arrival needed for position, when work complete when operate hydraulic stem again
Oil cylinder is shunk, drives mobile platform to be retracted back to original position backward while support wheel and movable pulley are rotated, reach a symbol
Close the constructing tunnel cantilever chassis of desired automatically retractable platform.
