Abstract

The invention discloses a sound barrier main girder keel rivet assembly device, which includes a general assembly frame and several assembly units, the assembly unit includes a bracket, a prefabricated frame, a closing device and a pressing device, and the closing device includes a device for pulling the prefabricated frame The first driving device and the sliding device for guiding the prefabricated frame, the pressing device includes the second driving device for applying force to the sound barrier main girder keel clip and pre-compressing the sound barrier main girder keel Tight hold down.

Description

technical field [0001] The invention relates to the technical field of sound barrier assembly, in particular to a sound barrier main girder keel rivet assembly device. Background technique [0002] As the main measure of sound insulation and noise reduction, sound barriers are widely used in railways, highways, municipal and other transportation facilities. A large number of high-speed railways have been put into use. High-speed rail sound barriers have been tested and developed in practice. Metal sound barriers have excellent Excellent sound insulation and noise reduction performance and service life, especially widely used in bridge sound barriers with load requirements. Existing sound barriers often adopt the method of panel assembly, for example, a kind of "A Sound Barrier Structure Frame Assembly Equipment" disclosed in Chinese patent documents, its announcement number CN109794768A, includes a frame, and a keel positioning mechanism arranged in the frame , the sound-ab...
