Abstract

The invention discloses a telescopic steel truss joint splicing device, which comprises a movable lifting platform and an operation platform, wherein the operation platform is positioned on the top of the movable lifting platform. The telescopic steel truss joint splicing device is characterized in that the operation platform comprises fixed platforms; the fixed platforms are fixedly connected to the top of the movable lifting platform; the fixed platforms have hollow structures; at least one telescopic platform is arranged inside each fixed platform; rollers are arranged on two opposite sides of each telescopic platform; a plurality of limiting blocks are arranged between each telescopic platform and each fixed platform; each fixed platform is further provided with a power mechanism for controlling the rollers to rotate. The device is safe and reliable, and is convenient to use; the safety of operators can be better protected, and the workload of the operators is reduced.

Description

technical field [0001] The invention relates to the field of bridge construction equipment, in particular to a telescopic steel truss beam joint assembly device. Background technique [0002] When assembling steel truss girders, in order to assemble bolts at the joints of steel truss girders between sections, it is necessary to set up a construction platform at each node position of steel truss girders to provide work space for construction personnel. At present, the common devices for building construction platforms are generally hanging ladders and scaffolding boards. The hanging ladders are welded or bolted by section steel; when the steel truss girders are assembled, the hanging ladders are temporarily fixed to the steel truss girders before the steel truss girders are hoisted. After the steel truss girder is hoisted in place, a scaffolding board is set up between the hanging ladders at the node position of the steel truss girder and fixed to form a temporary simple oper...
