Detailed description of the invention
For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
A kind of steel work folding house roof that the utility model provides drives and control system is made up of the main control unit of 1 in Fig. 11,2 driving chassis 2,2 groups of track groups 3,2 driven bogies 4.Main control unit 1 is connected by holding wire carries out two groups of Synchronization Control driving chassis 2 to walk with driving chassis 2, the supervision of driving chassis 2 start-stop and extreme position and control.Main control unit 1 can show folding house roof position and moving displacement in real time with touch-screen, the setting that prompt messages can carrying out is correlated with and operation.Main control unit 1 is provided with the signal input point be connected with fire fighting system, and in fire emergency situation, main control unit 1 can perform the on-off action meeting fire-fighting requirements.The mobile operation of whole folding house roof is undertaken by wireless or wired remote control handle.Remote-control handle directly carries out being connected realizing controlling functions with communication module in main control unit 1.Drive chassis 2 certainly to walk, driven bogie 4 is followed and is driven chassis and roof truss to move together.
Composition graphs 2, drives chassis 2 to comprise variable-frequency motor 2 14, position detecting element 15, the pinion 16 of control unit 5, speed-changing gear box 6, tooth bar 7, rail 8, vehicle frame 9, sliding support 10, guiding mechanism 11, wheel group 12, variable-frequency motor 1, band rotary encoder.Control unit 5 inside is integrated with frequency converter and PLC and controls for the rotating speed of motor and the collection of translational speed, and is connected by bus with between main control unit 1, carries out the execution of data transmission and master control instruction.Drive chassis 2 to have 4 wheel group 12 support frame 9, walk on two rail 8.Speed-changing gear box 6 has two, be arranged symmetrically in the side driving chassis 2, its output shaft end is with pinion 16, two pinions 16 engage the installation accuracy requirement that can reduce tooth bar 7 simultaneously with tooth bar 7, make driving force distributed in tooth bar 7 more points, reduce tooth stressed, improve tooth bar 7 and pinion 16 life-span, chassis runs more steady, and there is not the generation of wheel-slip.Rail 8 is clipped in the middle with wheel group 12 by two pinions 16 simultaneously, and effective restrict trolley wheel group de-orbits on end face.The arrangement length of tooth bar 7 is determined according to driving the walking length of chassis 2.Vehicle frame 9 is H-shaped steel construction piece, and crown center is fixed with sliding support 10.Its middle rack 7 upside-down mounting is below the frange plate of rail 8.Variable-frequency motor 1 and variable-frequency motor 2 14 have identical incoming frequency thus ensure that to output to two pinion 16 rotating speeds by speed-changing gear box 6 identical, also just achieves two pinion 16 synchronous axial system.Variable-frequency motor 2 14 afterbody is equipped with the rotating speed that rotary encoder is used for measuring motor, and measured value is fed back in the PLC in control unit 5, by the bus that connects to main control unit 1 measured value is input in the PLC of main control unit 1 and carries out corresponding comparison operation as the feedback signal of Synchronization Control and default value, and then realize the speed sync walking that two groups drive chassis 2 installation requirements.Sliding support 10 has two kinds of forms, the sliding support 10 of the irremovable slip of a kind of upper and lower two parts is arranged on chassis on one side, the another kind of transversely movable sliding support 10 of two parts is up and down arranged on another side chassis, overcomes the impact on chassis and rail beam of additional force that roof system transverse deformation produces with this.When implementing at the scene, the upper top of sliding support 10 is welded with the roof system girder steel strong point, and bottom and chassis end face are welded and fixed.Guiding mechanism 11 is arranged on the rear and front end of vehicle frame 9 speed-changing gear box with side body, and lateral load during for overcoming rack drives is on the impact of wheel group and chassis.Position detecting element 15 and be arranged on the roof system movement of rail beam side two limit positions near block slow down when can realize extreme position, to stop and extreme position always stops function, steady reliable and safety during for ensureing that roof system closes up and is opened to maximum position.
Driven bogie 4 structure does not have drive system, and all the other are all identical with driving chassis 2.
