FIG. 2 is an enlarged view of portion A of FIG. 1;
FIG. 3 is a side view of a preferred main rail.
Detailed Description
As shown in figures 1-2, a hydraulic and hydroelectric engineering is with overhauing cat ladder equipment, including the vertical ladder main part, it is the same with traditional vertical ladder, the vertical ladder main part also includes two main pole settings 1 and a plurality of main horizontal pole 2 that evenly set up between two main pole settings 1, and main pole setting 1 and main horizontal pole 2 generally adopt the steel pipe to make, and the interval of main horizontal pole 2 is usually between 25-35 cm.
The utility model discloses the biggest difference lies in, the bottom of main pole setting 1 is provided with adjusts the base, it is used for adjusting the length of main pole setting 1 lower extreme to adjust the base. The adjusting base comprises a first screw rod 3, a first rotating joint 4, a supporting body 5 and a rubber anti-skid pad 6 arranged at the bottom of the supporting body 5, which are sequentially connected from top to bottom, the upper end of the first screw rod 3 penetrates through the lower end of the main upright rod 1 and is in threaded fit with the main upright rod 1, the lower end of the first screw rod 3 is connected with the upper half section of the first rotating joint 4, and the lower half section of the first rotating joint 4 is connected with the supporting body 5; a first screw block 7 is arranged on the lower section of the first screw 3 for rotating the first screw 3, and the first screw 3 can be in the form of block, disc, wheel or the like.
The utility model discloses compare with traditional vertical ladder, put when needs are used at the subaerial performance of height unevenness such as stair, step, through rotatory first revolving piece 7 of twisting, drive first screw rod 3 and rotate to realize its flexible in main pole setting 1, and then realize the adjustment of main pole setting 1 hypomere length, need not to reuse lumber skid, soil heap, stone etc. and carry out the bed hedgehopping to the ground of low side, not only use convenience more, also guaranteed the stability of support.
The utility model discloses especially, be fit for the great occasion of ground height fluctuation and use, of course, when the adjustment range of main pole setting 1 is very big, the height of the bottom of adjusting the seat is great, for the convenience of the user step on the vertical ladder main part, does not influence the normal regulation of vertical ladder main part again. The utility model discloses better way can also be, the lower part of vertical ladder main part sets up assists the ladder, assist the ladder to include that two are assisted pole setting 8 and a plurality of even settings are assisted two horizontal poles 9 of assisting between the pole setting 8, the upper end of assisting pole setting 8 is provided with first rotating sleeve 10, first rotating sleeve 10 cover is established on by supreme second main horizontal pole 2 down to constitute normal running fit with main horizontal pole 2.
