Detailed Description

The present application is further illustrated with reference to specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present application. Further, it should be understood that various changes or modifications can be made to the present application by those skilled in the art after reading the teaching of the present application, and these equivalents also fall within the scope defined by the present application.

Example (b): just, portable moving type building ladder, the building ladder is four-legged ladder, the top of first ladder body 1 and second ladder body 2 all is fixed with the step board, it is articulated between the step board, first ladder body 1 is including two first support columns 3, be fixed with a plurality of crossbeams 4 between two first support columns 3, second ladder body 2 is including two second support columns 5, also be equipped with a plurality of crossbeams 4 between two second support columns 5, be equipped with logical groove 6 in the bottom of first support column 3, it runs through first support column 3 to lead to groove 6 along perpendicular to crossbeam 4 direction, the lateral wall that leads to groove 6 is fixed with articulated shaft 10 that is on a parallel with crossbeam 4, rotation is connected with wheel carrier 7 on articulated shaft 10, wheel carrier 7 one end is equipped with race 11, be equipped with the shaft 12 that is on a parallel with articulated shaft 10 in the race 11, be equipped with wheel 8 on the wheel shaft 12, wheel 8 rotates around wheel shaft 12 and wheel carrier 7 relatively.

Through 6 one end in the groove and being fixed with limiting plate 9, limiting plate 9 is located first support column 3 and is close to the lateral wall of second support column 5, and when wheel 8 was packed up, wheel carrier 7 did not influence the normal use of architectural ladder in submerging in the groove 6 completely. When the building ladder needs to be moved, the wheel carrier 7 is rotated around the hinge shaft 10, when the wheel carrier 7 is consistent and parallel with the first support column 3, the limiting plate 9 limits the rotation of the wheel carrier 7 to the maximum extent, the lowest point of the wheel 8 is lower than the ground of the first support column 3 at the moment, the building ladder is conveniently moved by using the wheel 8, shoulder resistance and hand lifting are not needed, the working strength of workers is effectively reduced, and the moving efficiency of the building ladder is improved. In the advancing process, the wheel carrier 7 is subjected to the force opposite to the advancing direction, so that the wheel carrier 7 cannot rotate towards the direction far away from the limiting plate 9, and therefore the wheels 8 cannot be folded in the moving process of the building ladder, and the building ladder can be moved more safely.

In the use of building ladder, when the ground holding surface unevenness, for the stability of better assurance building ladder, guarantee workman's safety is equipped with high micromatic setting in the bottom of second support column 5, and high micromatic setting can adjust the effective length of second support column 5. In the use of building ladder, can only be because the diagonal support column can not all contact ground and rock as the value, consequently set up high micromatic setting in the bottom of two second support columns 5 and can satisfy building ladder's diagonal support column and support subaerial completely, avoid building ladder to take place to rock.

The height fine-adjustment device comprises an adjusting rod 14 which is connected with the second supporting column 5 in a plugging and pulling mode, a supporting part 13 is arranged at one end, far away from the second supporting column 5, of the adjusting rod 14, namely the bottom of the adjusting rod 14, and the sectional area of the supporting part 13 is larger than that of the adjusting rod 14, so that the supporting area is enlarged, and the stability of the building ladder is guaranteed. The bottom of second support column 5 is equipped with the jack along 5 length direction of second support column, adjust pole 14 insert in the jack with jack sliding connection, the lateral wall of jack is equipped with the first regulation hole 15 that runs through 5 lateral walls of second support column, it is equipped with a plurality of second regulation holes 16 to adjust 14 lateral walls of pole, it is connected with dead lever 17 to pull out in the first regulation hole 15, dead lever 17 runs through first regulation hole 15 and inserts in second regulation hole 16 to adjust pole 14 and second support column 5 relatively fixed. A magnet 18 is fixed in the second adjusting hole 16, and the end of the fixing rod 17 is a metal iron component. The adjusting rods 14 are inserted into the inverted insertion holes at different depths to realize fine adjustment of the height of the second supporting column 5, and the fixing rods 17 penetrate through the first adjusting holes 15 and are inserted into the second adjusting holes 16 to realize fixation of the adjusting rods 14 and the second supporting column 5. Through fixing magnet 18 in second regulation hole 16 and adsorbing dead lever 17, avoid because the condition that removes the building ladder vibration and lead to dead lever 17 to break away from second regulation hole 16 even first regulation hole 15, prevent losing of dead lever 17.
