Description
Technical field
The present invention relates to a kind of coal mine equipment, relate in particular to a kind of combined type angle-adjusting foot stairs for downhole inclined gallery.
Background technology
In the Coal Production real process, inclined gallery are very general, and it plays the effect of interim transportation in the coal mining process, half driving, half pedestrian.At present, pedestrian's ladder is to construct with bluestone board and cement to form, disposable use, and along with the transfer of work plane, tunnel and People's Bank of China's ladder are discarded in the lump, cause very serious waste.
Summary of the invention
The purpose of this invention is to provide a kind of combined type angle-adjusting foot stairs for downhole inclined gallery that can reuse, economize on resources.
For achieving the above object, the technical solution used in the present invention is:
A kind of combined type angle-adjusting foot stairs for downhole inclined gallery comprises left and right two framing beams, is characterized in: but Vierendeel girder is assembled by the assembly unit side plate, is fixedly connected with pedal between the left and right Vierendeel girder.
According to described combined type angle-adjusting foot stairs for downhole inclined gallery, be characterized in: but described assembly unit side plate two ends have connection-peg, interface respectively, connection-peg is corresponding with interface, but the connection-peg of adjacent two assembly unit side plates can be fixedly plugged in interface, but also have fixing hole, adjustment hole on the assembly unit side plate, but the fixing hole of adjacent two assembly unit side plates is corresponding with adjustment hole; Described pedal comprises plate body, the anterior left and right two ends of plate body all have fixed axis, but but left and right fixed axis passes fixing hole on the left and right assembly unit side plate, fixedlys connected with left and right assembly unit side plate, left and right two ends, plate body rear portion all have regulating shaft, but but left and right regulating shaft pass adjustment hole on the left and right assembly unit side plate, fixedly connected with left and right assembly unit side plate.
According to described combined type angle-adjusting foot stairs for downhole inclined gallery, be characterized in: the cross section of described fixed axis is for circular; The cross section of described regulating shaft is oval.
According to described combined type angle-adjusting foot stairs for downhole inclined gallery, be characterized in: but have two or more adjustment holes on the described assembly unit side plate.
But the present invention's demolition, installation can be reused in different tunnels, have saved lot of materials, reduce mining costs.

Below in conjunction with the drawings and specific embodiments the present invention is further described:
A kind of combined type angle-adjusting foot stairs for downhole inclined gallery as shown in Figure 1 and Figure 2, comprise left and right two framing beams 3, but Vierendeel girder 3 is assembled by assembly unit side plate 1 (referring to Fig. 3), is fixedly connected with pedal 2 between the left and right Vierendeel girder 3 (referring to Fig. 4-Fig. 7).But assembly unit side plate 1 two ends have connection-peg 11, interface 14 respectively, connection-peg 11 is corresponding with interface 14, but the connection-peg 11 of adjacent two assembly unit side plates 1 can be fixedly plugged in interface 14, but also have fixing hole 13, adjustment hole 12 on the assembly unit side plate 1, but the fixing hole 13 of adjacent two assembly unit side plates 1 is corresponding with adjustment hole 12; Pedal 2 comprises plate body 23, plate body 23 anterior left and right two ends all have fixed axis 21, but but left and right fixed axis 21 passes fixing hole 13 on the left and right assembly unit side plate 1, fixedlys connected with left and right assembly unit side plate 1, left and right two ends, plate body 23 rear portions all have regulating shaft 22, but but left and right regulating shaft 22 pass adjustment hole 12 on the left and right assembly unit side plate 1, fixedly connected with left and right assembly unit side plate 1.As shown in Figure 7, the cross section of fixed axis 21 is circular; The cross section of regulating shaft 22 is oval, 21 interconnect functions of fixed axis, 22 regulating actions of regulating shaft.In the present embodiment, but have two or more adjustment holes 12 on the assembly unit side plate 1.
Embodiment recited above is described preferred implementation of the present invention; be not that design of the present invention and scope are limited; under the prerequisite that does not break away from design concept of the present invention; common engineers and technicians make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
Manufacturing materials of the present invention can be selected shape or engineering plastics for use, top, following mode that Vierendeel girder can be also can be left side, right side mode, and the present invention can regulate the gradient of pedal according to the difference of inclined gallery angle, make Vierendeel girder and inclined gallery angle unified, make pedestrian's pedal remain level.The present invention can make different lengths such as 0.3m to 3m as required, and adjustable angle when work plane shifts, can shift with track one foldover dress between 8 °～25 °, realizes reusing.
The present invention is dismantled and assembled, adjustable angle, saved a large amount of raw material, has improved inclined gallery and has finished efficient, has reduced labour intensity (the present invention being installed than the time much shorter of constructing People's Bank of China's ladder), reduce mining costs, simple in structure, in light weight, change and damage parts conveniently, can be repeatedly used.
