Description
The utility model relates to leveling device, particularly the building operation leveling device of elevator.
Existing leveling device, the digital control choosing layer instrument produced of Guangdong Province's Shunde County radio one factory for example, mainly contain the floor preliminary election, the floor counting, comparator circuit, several parts such as output circuit are formed, working process is such, by the predetermined number of floor levels of keyboard input, deliver to comparator circuit after deciphering, revise counting by preselected circuit, demonstrate by display circuit simultaneously and preset number.In addition by a travel switch that is arranged on the elevator craning cage, obtain the floor signal by the iron that bumps that each floor presets, whenever pass through first floor, the travel switch adhesive once, export an impulse singla, deliver to the floor counting circuit, its result delivers to display circuit on the one hand, with indication elevator place floor; Deliver to comparator circuit simultaneously, compare with presetting the building, when floor arrival was scheduled to floor, comparator circuit promptly had output signal, sends control signal by output circuit, and motor is steadily stop just, and elevator is accurately realized flat bed.
This leveling device, advantage are that signal wire (SW) is reduced to one, have reduced manufacturing cost.Shortcoming is that the travel switch in this root signal wire (SW) and the elevator joins, and is following elevator and is moving up and down, damages easily.Be that the iron that bumps by each floor position collides repeatedly on the signal preparation method, also cause the displacement and the damage of bumping iron easily.Installation, debugging and the maintenance of each floor position being bumped iron are also very difficult.And this leveling device volume is bigger, and people wish to find a kind of better leveling device.
The purpose of this utility model provides a kind of leveling device that overcomes above-mentioned shortcoming, and this improved leveling device is applied to leveling device with microcomputer technology for the first time, has the signal deriving means technology that microcomputer carries out signal conditioning and advanced person of using.
The purpose of this utility model is to realize like this, by monolithic 8031 microcomputers of Intel Company in the eighties release, the input and output peripheral circuit that integrated circuit TIL113,74LS04,74LS74,74LS221,74LS266 form, integrated circuit 8155,74LS07,75452 interface circuits of forming, a signal wire (SW) and a speed sensor and several push switch and read out instrument are formed.Be characterised in that signal wire (SW) is fixed on the derrick,, guarantee the reliable and stable of signal wire (SW) not with the elevator rise and fall.Speed sensor is made up of two HALL-IC, magnet steel, leading sheave and sensor frames.HALL-IC is by means of the effect of magnet, and the leading sheave acquisition speed impulse singla from the elevator of steel cable transmission changes the method for bumping the iron number of winning the confidence that relies at present.The benchmark limit is closed switch and is installed on the derrick.
The utility model is compared with present leveling device, be the installation method of signal wire (SW) or signal obtain and the identification of signal is handled and output all has bigger improvement.Have that volume is little, function is strong, the reliability height, install simple, easy to maintenance, advantage such as production easily.Particularly the flat bed pulse can random variation, and the leveling error of having avoided disturbing factor to cause is a kind of leveling device of a new generation.
Accompanying drawing 1 is the utility model electrical principle block diagram.
Accompanying drawing 2 is external form scheme drawings of the present utility model.
Accompanying drawing 3 is scheme drawings of the utility model speed sensor.
Accompanying drawing 4 is the utility model signal input circuit figure.
Accompanying drawing 5 is the utility model N Reference Alignment and signal output apparatus figure.
1 magnet steel among the figure, 2 pulleys, 3,16 HALL-IC, 4 flat bed preliminary elections or pulse show that 5 floors show, 6 output indications, 7 knobs that reset, 8 source switchs, 9 debugging keys, 10 superelevation keys, 11 slippage keys, 12 clearing keys, 13 flat bed keys, 14 pulse keys, 15 speed sensors
Followingly the utility model is further described below with reference to accompanying drawing.
With reference to accompanying drawing 2 and accompanying drawing 3, speed sensor is by two HALL-IC 3(CS6839) and 16(CS6839), magnet steel, leading sheave and sensor frame are formed.Two HALL-IC 3(CS6839) and 16(CS6839) have alternate position spike, gap is preferably between the 4mm-8mm.Two HALL-IC 3 and 16 produce speed pulse signal by means of the magnet steel 1 that is affixed on the pulley 2, send into the micro controller system travel direction by one attached to the signal wire (SW) on the derrick and differentiate.One side of leading sheave 2 is pasted magnet steel 1 with epoxy, and at regular intervals between every block of magnet steel, spacing is greater than 1.5cm.Also at regular intervals between magnet steel 1 and the HALL-IC 3,16, spacing is preferably in 1-3mm.Sheave shaft overcoat antifriction-bearing box at speed sensor 15.With reference to accompanying drawing 3 and accompanying drawing 4, when the rotation of leading sheave 2 anticlockwise directions, during HALL-IC 16 conductings, optocoupler IC
2Conducting.Because so HALL-IC 3 previous conductings are optocoupler IC
1Also conducting already.At this moment d type flip flop IC
3D input end (74LS74) is a high level, and the CP control end also is a high level, and the Q mouth is high level, sends into IC
4(8031) as the anticlockwise direction level; Otherwise, when the leading sheave right-hand revolution, during HALL-IC 16 conductings, optocoupler IC
2Conducting, because also not conducting of HALL-IC 3, so optocoupler IC
1Not conducting, at this moment the D input end is a low level, and the CP control end is a high level, and the Q mouth is low level, sends into IC
4(8031) as the clockwise direction level.With reference to accompanying drawing 5, when elevator rises or descend operation, can collide the benchmark limit switch EJ that is installed on the derrick, limit switch closure, optocoupler IC
5Conducting.This moment IC
4(8031) P1.0 is a low level, under the programmed instruction commander, realizes that basic pulse is from dynamic correction.Limit switch can be installed in arbitrary height on the derrick, preferably is installed between the 0.1-2.5m.With reference to accompanying drawing 5, work as IC
4When (8031) low level is controlled in output, through driver IC
8(74LS07), make optocoupler IC
