Detailed Description
As shown in fig. 1 and fig. 2, the combined insulated hard ladder disclosed in this embodiment is composed of two parts, namely a ladder head 1 and a ladder main body 2. The existing folding insulating hard ladder is selected as the ladder body 2 and is suitable for being used as a ladder stand of a transformer substation framework, and the top ends of the two longitudinal rods of the ladder body are provided with lug plates 21 so as to install the ladder head 1.
The ladder head 1 is composed of three parts, namely a bracket 11, a middle support 12 and a climbing assembly 13.
The bracket 11 is an H-shaped frame and includes a pair of vertical rods 111 and upper, middle and lower crosspieces 112. The bottom end of the upright rod 111 is provided with a mounting ring; the two vertical rods are arranged in parallel, and the upper crosspiece, the middle crosspiece and the lower crosspiece are respectively arranged between the two vertical rods through the connecting seats 14. The connecting seat 14 comprises a rectangular sleeve and an annular sleeve, and the annular sleeve is horizontally arranged on the inner side of the rectangular sleeve in the axial direction of the annular sleeve; the sleeve hole of the rectangular sleeve is matched with the upright post, and the sleeve wall is provided with a limiting hole; the sleeve hole of the annular sleeve is matched with the crosspiece, and the sleeve wall is provided with a limiting hole; during installation, the rectangular sleeve is sleeved outside the vertical rod and locked by the fastener screwed into the limiting hole, and the end part of the crosspiece is inserted into the annular sleeve and locked by the fastener screwed into the limiting hole.
The center brace 12 includes a horizontal brace 121, a frame hoop 122, and a foot clasp 123. The horizontal stay bar 121 includes a connection ring, a stay bar main body and a connection sleeve, which are respectively disposed at both ends of the stay bar main body. The frame hoop 122 includes an arc-shaped section and a straight-line section, one end of the straight-line section is connected with the connecting sleeve, and the other end of the straight-line section passes through the connecting sleeve and then is connected with the foot buckle through the adapter 124. And a spring 15 is provided between the climber 123 and the corresponding upright.
