DETAILED DESCRIPTION

[0023] To clearly illustrate the technical features of the present application, the present application will be described below through specific embodiments.

[0024] As shown in Figures 1-5 the utility model discloses two groups of support frames set up front and back, and each group of support frames includes two vertically arranged and internally hollow support poles 1, a plurality of horizontal step poles 2 are fixed between the two support poles 1, the plurality of step poles 2 are evenly distributed upwards and downwards, and the staff can conveniently climb upwards through the step poles 2. In order to improve the support stability of the support frame, the two support poles 1 on the same side of different groups of support frames are connected with the cross-fixed reinforcing poles 3, so that the support stability is enhanced.

[0025] A lifting pole 4 is inserted into each support pole 1, a plurality of transverse fixing pin holes 5 are arranged on each lifting pole 4, the plurality of transverse fixing pin holes 5 are evenly arranged along the long axis direction of the lifting pole 4, the pin 6 is selected to be inserted into the transverse fixing pin hole 5 to fix the position of the lifting pole 4, the pin 6 is selected to be inserted into the appropriate transverse fixing pin hole 5 according to the construction requirement, and the lifting pole 4 is limited by the two ends of the pin 6 stopping at the top end of the support pole 1. The top end of each lifting pole 4 is vertically fixed with the step 7, the lifting pole 4 is raised to move the step 7 upwards, and the lifting pole 4 is lowered to move the step 7 downwards.
