Abstract
A safety loading device of a building construction tower crane comprises a base, a lower rotator, a pylon, a rotating shaft sleeve, a support pillar, a connecting rod, an upper rotator, a draw bar and a crane jib, wherein the lower rotator is installed on the base, the pylon is arranged above the lower rotator, the upper rotator is installed above the pylon, the rotating shaft sleeve is installed between the lower and the upper rotators, the upper end of the support pillar is connected with the crane jib, the lower end of the support pillar is connected with the lower rotator, the support pillar is connected with the rotating shaft sleeve through the connecting rod, and the draw bar is installed on the crane jib. The utility model has the following advantages that: the safety loading device of the building construction tower crane can effectively solves the potential safety hazards existing in the existing building construction tower crane, and has a good safety effect, a simple structure, lower production cost, and convenience in installation and maintenance.
Description
Technical field
The utility model relates to a kind of load-carrying safety device, is specifically related to a kind of building operation tower crane load-carrying safety device.
Background technology
At present, in lifting appliance commonly used, tower crane is a kind of important lifting appliance, and it has characteristics such as floor area is few, the lifting radian is big, delivery is convenient.But present tower crane device has great defective, and the head end of lifting and tail end load carrying ability have a long way to go, in order to enhance productivity, have to establish multistage lifting loading point, every section load carrying ability gradually reduces, if operation reconnaissance error is easy to cause safety misadventure, causes great loss.
The utility model content
The purpose of this utility model is to provide the tower crane load-carrying that a kind of safe effect is good, simple in structure, productive costs is low, easy to installation and maintenance safety device.
The technical scheme that the utility model adopted is:
A kind of building operation tower crane load-carrying safety device comprises pedestal, following spinner, king-post, shaft sleeve, fore-set, pitman, goes up spinner, pull bar and arm; Spinner is installed down on the pedestal, there is king-post following spinner top, the king-post top is equipped with spinner, between following spinner and the last spinner shaft sleeve is installed, the fore-set upper end links to each other with arm, the fore-set lower end links to each other with following spinner, and fore-set links to each other by pitman with shaft sleeve, and pull bar is installed on the arm.
During use, spinner in the startup, driving down synchronously by shaft sleeve, spinner rotates, drive by pitman then and withstand rotation, rotate at any angle thereby drive arm, finish lifting and unload thing work, owing to connect into last spinner, shaft sleeve, following spinner, fore-set and arm as a whole, so just can be transported to tail end to the weight that head end is sling always, solve the potential safety hazard of branch load-carrying lifting.
The utlity model has following advantage: can solve the potential safety hazard that existing building construction tower crane exists effectively, safe effect is good, and is simple in structure, and productive costs is low, and is easy to installation and maintenance.
