Abstract
The utility model relates to a tower crane conversion base which is connected between a tower crane foundation section bottom plate and a tower crane foundation through foundation bolts. The tower crane conversion base comprises an upper bottom plate, a lower bottom plate and a plurality of rib plates in welding connection with the upper and the lower bottom plates, wherein bolt holes matched with bolt holes reserved on the tower crane foundation are formed on the lower bottom plate, and the lower bottom plate is mounted on the tower crane foundation through foundation bolts; and bolt holes matched with the bolt holes preset on the tower crane foundation section bottom plate are formed on the upper bottom plate, and the upper bottom plate is mounted on the tower crane foundation section bottom plate through foundation bolts.
Description
Technical field
The utility model relates to a kind of tower crane accessory, refers to a kind of tower crane conversion cradle especially, and affiliated science and technology field is engineering construction, and affiliated specialty is building structure and design.
Background technology
In the existing building engineering, the tower crane of casting concrete in advance, respectively has a tower crane joint base plate on four feets of tower crane bottom, four drift angle places of this base plate respectively offer a bolt hole, on concrete tower crane foundation, reserve four groups of bolts hole according to the tower crane model that will use, every group of bolt hole comprises four bolts hole, the bolt hole of the position of each bolt hole and tower crane joint base plate is consistent with each other, tightens two bolts hole by holding-down bolt and tower crane is saved base plate is fixed on the tower crane;
But, if engineering needs because of construction midway, need to change the tower crane model, because the existing tower crane of engineering, the holding-down bolt that the bolt hole of tower crane constitutes is installed by the housing size and former tower crane installation housing is measure-alike, but it is different that the holding-down bolt that the base section bed bolt hole of the new tower crane of installing with need constitutes is installed the housing size, can't install.
Summary of the invention
Main purpose of the present utility model is: but provide a kind of installation work to change the base of the tower crane of model midway.
For achieving the above object, the utility model provides a kind of tower crane conversion cradle, be connected between tower crane joint base plate and the tower crane by holding-down bolt, include upper plate, lower shoe and the plural piece gusset that is welded to connect upper and lower bottom plate, offer the bolt hole that is complementary with the tower crane prepared screw-bolt hole on the described lower shoe, lower shoe is installed on the tower crane by holding-down bolt; Offer the bolt hole that is complementary with the default bolt hole of tower crane joint base plate on the described upper plate, upper plate is installed on the tower crane joint base plate by holding-down bolt.
Use tower crane conversion cradle of the present utility model, former tower crane is matched with the tower crane joint base plate of changing the back novel model, new tower crane is fixed on the former tower crane.
