Embodiment Construction

[0019] The pitching motor (12) drives the pitching mechanism driving shaft (14) to rotate through the pitching mechanism coupling (13). When the cylinder (2) rotates, one end of the pitch mechanism wire rope (5) is fixed on the pitch mechanism reel (2), and the other end is fixed on the top of the tappet (10). The rotation of the reel (2) makes the pitch mechanism wire rope (5) Release or reel in to achieve the pitching motion of the tappet. The rotary motion motor (4) is fixed on the rotary motion platform (22), and the rotary motion motor (4) drives the small gear (18) to move, and through the engagement with the large gear (19), the rotary motion platform (22) and its The rotary shaft (21) above realizes rotary motion. The hoisting motor (15) drives the hoisting mechanism driving shaft (17) to rotate through the hoisting mechanism coupling (16), and the driving shaft (17) is connected with the hoisting mechanism reel (1) by a key, so that Drive the hoisting mechanism reel...

Abstract

The invention relates to a jib crane test bed and belongs to the technical field of crane transport machinery. The jib crane test bed is provided with an elevating mechanism, a swing mechanism, a lifting mechanism and a motion control system. The elevating mechanism adopts a cantilever crane swing mechanism, and a transmission solution adopts wire rope pulley block transmission; the swing mechanism adopts a rolling bearing type rotary supporter, and a transmission solution adopts gear pair transmission; and the lifting mechanism adopts a transmission solution of a wire rope pulley block. The motion control system controls two sets of servo systems and a set of step motor drive system through a PC to drive an amplitude change mechanism, the swing mechanism and the lifting mechanism respectively to operate. The design and the construction of the test bed provide reliable test data for researching the mechanical property of the jib crane, and have important theoretical significance and practical value for realizing jib crane automation, reducing the accident rate, and improving the working efficiency, the safety and the reliability.

Description

technical field [0001] The present invention designs a lifter crane test bench. The purpose of the present invention is to provide test equipment for researching the dynamic characteristics of the tappet crane, exploring the key technology for realizing the automation of the tappet crane, reducing the accident rate, improving work efficiency, safety and reliability. The utility model belongs to the technical field of hoisting and transporting machinery. Background technique [0002] Tappet cranes are widely used in ports, oil fields and transportation industries, but currently they are mainly operated manually, with a low degree of automation and a high accident rate. In order to fundamentally solve these problems, the present invention designs a lifter crane test bench for studying the dynamic characteristics of the lifter crane and the effectiveness of the control strategy, as well as measures to improve the safety, stability, and reliability of the lifter crane. At pres...
