Embodiment Construction
[0009] Examples, see attached figure 1 , the folding maintenance work platform is welded by 50×20×3mm square tubes and hinged by pin 4 hinges. The height of the main pillar 5 is 1140mm. The ladder 7 is welded together in parallel, and the distance between the two main pillars 6 is 600mm. The following of the main pillar 5 is movably connected with the level 6 at an inner acute angle with the hinge pin 4, and the length of the horizontal support 6 is 540mm. The top of the main pillar 5 is hinged with the upper platform 1 with the hinge pin 4, and the front end of the upper platform 1 is provided with a fixed plate groove 1-1. In the middle of the main pillar 5 and the upper platform 1, the hinge pin 4 is used to connect one end of the support rod two 3 and the support rod one 2 respectively, and the other end of the support rod one 2 and the support rod two 3 is hinged with the hinge pin 4 Together, the inner angle between the support rod two and the main pillar 5 forms a...

The invention belongs to a maintenance tool in the power industry and in particular relates to a folding type maintenance work platform. The folding type maintenance work platform comprises an upper platform (1), main supporting columns (5) and horizontal brackets (6), wherein two horizontal transverse ladders (7) are fixedly arranged between the two parallel main supporting columns (5); two horizontal brackets (6) are moveably connected below the two parallel main supporting columns (5) through hinged pin shafts (4) in an acute angle mode; the top ends of the supporting columns (5) are moveably connected with the upper platform (1) through the hinged pin shafts (4); a fixed pressing plate groove (1-1) is formed on the front end head of the upper platform (1); the middle parts of the outer side of the upper platform (1) and the main supporting columns (5) are connected with one end of each of a supporting inclined rod I (2) and a supporting inclined II (3) through the hinged pin shafts (4); the other ends of the supporting inclined rod I (2) and the supporting inclined II (3) are moveably connected; and the inner include angle alpha of the supporting inclined II (3) and the main supporting columns (5) is 30 degrees. The folding type maintenance work platform can be flexibly applied to an on-off mechanism of a power industry system, greatly saves work time, improves work efficiency and safety and can be folded and stored when being not used.
Description
technical field [0001] The invention belongs to maintenance tools in the electric power industry, in particular to a foldable maintenance work platform. Background technique [0002] In the maintenance of sulfur hexafluoride circuit breakers in power transmission and transformation, because there is no special platform, a pier-type concrete foundation is used, and the switch and mechanism are directly seated on the foundation, so there is not enough space for mechanism maintenance. , can only use the ladder to go up and down, which brings great inconvenience to the maintenance work, takes time and effort, and is easy to cause personal safety failure. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned technical deficiencies, and provide a foldable maintenance work platform that is easy to use, good in stability and easy to move. [0004] The technical scheme adopted by the present invention to solve the technical probl...
