Bridge type aerial work platform

Abstract

The invention relates to an aerial work platform, in particular to a bridge type aerial work platform. The bridge type aerial work platform comprises a machine base assembly, a wheel assembly, a telescopic arm assembly and a platform assembly. A horizontal arm is arranged at the upper end of the telescopic arm assembly, a gear is fixedly arranged on the upper surface of the horizontal arm, a sliding groove is formed in the inner ring of the gear, a rotary plate is arranged on the sliding groove, the upper end of the part, protruding out of the gear, of the rotary plate is connected with the platform assembly through a bolt, a screw rod device is arranged on the side of the part, protruding out of the gear, of the rotary plate, the screw rod device comprises an outer shell, a power driving device and a screw rod, the outer shell is integrally connected with the rotary plate, one end of the screw rod is in transmission connection with the power driving device, and the other end of the screw rod is meshed with the gear. The bridge type aerial work platform has the advantages of being capable of effectively expanding the rotating range of the platform.

Description

technical field [0001] The invention relates to an aerial work platform. Background technique [0002] Aerial work platform is a product that serves mobile high-altitude operations such as aerial work, equipment installation, and maintenance in various industries. The related products of aerial work platforms mainly include: scissor-type aerial work platforms, vehicle-mounted aerial work platforms, articulating-arm aerial work platforms, self-propelled aerial work platforms, aluminum alloy aerial work platforms, and cylinder-type aerial work platforms. [0003] For the crank arm aerial work platform, there are diesel engine self-propelled, battery self-propelled, trailer-type, with telescopic arms, which can be extended to work, cross certain obstacles or lift at one place to carry out multi-point operations; 360-degree rotation, platform load capacity It is large enough for two or more people to work at the same time and can carry certain equipment; the lifting platform ha...

Problems solved by technology

Articulated boom aerial work platforms can be divided into two types: straight arm and curved arm according to the way of arm extension. They are mostly used in places with high height requirements such as shipyards. This type of machine is safe and easy to move, but the cost is high

However, the platform rotation of the existing crank-arm type aerial work platform is limited. The rotating structure is arranged between the machine base and the telescopic arm, and the telescopic arm drives the platform to rotate, so that the rotation range is limited by the telescopic arm.
