Description

Jib crane test bed
Technical field
The present invention has designed jib crane test bed.The objective of the invention is in order to study the jib crane dynamics, explore the gordian technique that realizes the jib crane robotization, reduce accident rate, increase work efficiency, security, reliability provide testing equipment.Belong to the handling machinery technical field.
Background technology
Jib crane is used for harbour, oil field and carrier in a large number, but is that automaticity is low based on manually-operated at present, and the accident rate height.In order fundamentally to address these problems, the present invention designs jib crane test bed, is used to study the validity of jib crane dynamics and control strategy, and the measure that improves jib crane security, stability, reliability.Have not yet to see relevant jib crane test bed report.
Summary of the invention
The present invention has designed jib crane test bed luffing mechanism, slew gear, lifting mechanism and kinetic control system, as shown in Figure 1 and Figure 2.
1. luffing mechanism technical scheme
Luffing mechanism adopts the crane swing motion, and transmission scheme adopts the transmission of wire rope pulley group.Luffing motor (12) drives luffing mechanism main drive shaft (14) revolution by luffing mechanism shaft coupling (13), adopt key to be connected between luffing mechanism main drive shaft (14) and the luffing mechanism reel (2), thereby driving reel (2) rotates, luffing mechanism wire rope (5) one ends are fixed on the reel (2), the other end is fixed on the top of tappet (10), the revolution drive luffing mechanism wire rope (5) of reel (2) is decontroled or is involved in, thereby realizes the luffing of tappet.
2. slew gear technical scheme
Slew gear adopts the rolling bearing type slewing supporting device, and transmission scheme adopts the gear pair transmission, as shown in Figure 3.Gyration motor (4) is fixed on the gyration platform (22), motor (4) driving pinion (18) motion, by with the engagement of gear wheel (19), make gyration platform and top revolving shaft (21) thereof realize gyration.
3. lifting mechanism technical scheme
Hoisting gear adopts pulley drum group transmission scheme.The motion motor (15) that hoists drives lifting mechanism main drive shaft (17) rotation by lifting mechanism shaft coupling (16), adopt key to be connected between main drive shaft (17) and the lifting mechanism reel (1), thereby drive lifting mechanism reel (1) revolution, wire rope one end is fixed on the reel (1), the other end is fixed on the suspension hook (11), and the centre has lifting mechanism angle sheave (9) to support.The rotation drive wire rope (7) of reel (1) is decontroled or is involved in, thereby realizes the decline or the rising of suspension hook (11), reaches the purpose of lifting goods.
4. kinetic control system scheme
The jib crane pilot system drives luffing mechanism, slew gear and lifting mechanism operation respectively by cover PC control two cover servo-drive systems and a cover driving system of stepping motor.Every suit servo-drive system all is made up of motion controller, servo-driver, servomotor, driver adopts PANASONIC MSDA043A1A servo-driver, motor adopts the small-sized little inertia MSMA022A1C servomotor of PANASONIC, 11 line 2500P/r incremental optical-electricity encoders are contained on the motor shaft, measure the corner and the rotating speed of motor.
Advantage of the present invention is luffing mechanism, the slew gear of simulation jib crane, the motion of lifting mechanism, by displacement and the speed that scrambler is measured luffing, gyration, hoisted and move, measure the motion and the swing situation of load in real time by camera.The design of this testing table and the dynamics that is built into the research jib crane provide reliable test data, to realizing the jib crane robotization, reduce accident rate, increase work efficiency, security, reliability has great significance and be worth.
