Description
Technical Field
The utility model belongs to the technical field of the tower machine installation, especially, relate to a novel tower machine standard festival cat ladder mounting structure.
Background
At present, a vertical ladder and an inclined ladder are installed on a ladder stand used by a standard section of a tower crane. In the past, the inclined ladder mounting mode is that two ends are connected through bolts, and the mounting mode has more parts and longer preparation time for mounting.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a novel tower machine standard festival cat ladder mounting structure who has solved the problem that wastes time and energy of cat ladder installation in the past.
The utility model is achieved by the following concrete technical means:
a novel ladder stand mounting structure for a standard section of a tower crane comprises the standard section, a ladder stand, a hanging plate, a connecting plate and a fastening bolt; the crawling ladder is composed of two vertical plates and a plurality of cross rods uniformly distributed between the two vertical plates, a hanging plate is arranged on one side of the top of each standard section, hook grooves are formed in the hanging plate, and the cross rods at the uppermost ends of the crawling ladder are clamped in the hook grooves; the bottom of the standard knot is provided with a connecting plate, the connecting plate is provided with a fastening bolt, the bottom of the vertical plate is provided with a waist hole, and the fastening bolt penetrates through the waist hole and is in threaded connection with a nut.
Further, the link plate on standard festival top is located the one side of being close to marking time, and the connecting plate of bottom is located the one side of keeping away from marking time, and the cat ladder is the slope form.
Furthermore, the cross rod is square tubular and is made of aluminum alloy.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model discloses a cat ladder upper end connected mode adopts the direct-hanging type, and directly uses the horizontal pole of cat ladder to directly hang, need not additionally to weld the couple, and the lower extreme adopts the bolt fastening formula, and upper end link plate designs into curved hook-like, and the cat ladder is difficult for droing after cat ladder lower extreme bolt installation. Whole cat ladder installation only need install two bolts of lower extreme can, very big reduction the preparation operating time of installation, labour saving and time saving has solved the problem that the cat ladder installation wasted time and energy in the past.
