The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model 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 utility model; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design concept; common engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that the utility model is asked for protection all is documented in claims.
