Abstract
The utility model relates to a vertical moved electromagnetic elevator, which is composed of a head sheave, a derrick, a suspension cage, drawing steel cables, and a linear motor in the form of drive. The secondary electrode of the linear motor is fixed on the derrick, and the primary electrode of the linear motor is fixed on the suspension cage, a platform, or a counterweight iron, or the suspension cage, the platform, and the counterweight iron. A gap remain between the primary electrode of the linear motor and the secondary electrode of the linear motor. The utility model has the advantages of compact structure, reasonable design, low cost, stable running, flexible control, convenience, and energy saving and can be widely used for the lifters of the construction, freight transportation, personnel transportation, underwater operation. The utility model can also be used for the poor environment of dust pollution.
Description
The utility model relates to the electromagnetic lifter of a kind of elevator, particularly a kind of vertical operation.
Elevator domestic at present, external perpendicular movement is the elevator of the deceleration of secondary planar envelope worm gear pairs, rack-and-gear transmission or the transmission of high-rise high-speed hydraulic machinery.They all have, and complex structure, cost height, noise are big, vibration is big, driving efficiency is low, heating is serious, and shortcomings such as leakage of oil, fault are many, service expenditure height often take place.Preresearch estimates, only the productive costs of four of worm gear reducers, rack-and-gear, velocity limiter, motor accounts for 40% of complete machine cost.
The purpose of this utility model provides a kind of be used as power electromagnetic lifter of vertical operation in source of linear electric motors that adopts.
Task of the present utility model realizes with following mode: the utility model by head sheave, derrick, cage, drag and draw steel rope and constitute, linear electric motors are secondary to be fixed on the derrick, elementary cage or platform place or counterweight iron place or cage or platform and counterweight iron place, the gapped δ between linear electric motors are elementary and secondary of being installed in of linear electric motors.Linear electric motors secondary is separately fixed on every derrick joint, becomes continuous linear electric motors secondary on the derrick that derrick joint closed assembly becomes.The linear electric motors that be equipped with at cage or platform or counterweight iron place are elementary one or more.The gap delta value is 0.5mm to 3.5mm.The secondary installation site of linear electric motors becomes substantially parallel placement or basic vertically placement with the derrick side.The linear electric motors secondary materials is aluminium sheet or copper coin or copper base-steel bi-metal plate or steel plate.Linear electric motors are elementary to be installed in the secondary side of linear electric motors or to become relative symmetry to install in the secondary two sides of linear electric motors.
These facility have compact conformation, mechanism design reasonable, because the ingenious cooperation of having used linear electric motors or many linear electric motors causes this building hoist to be different from other various building hoists.And have following advantage:
1, rise dynamicthrust big, do not have centnifugal force, be not subjected to speed limit, therefore can realize quickening on a large scale and slow down (braking), in the required speed range of building hoist (about 1-1.5m/ second) make full use of the end effect of linear electric motors, can increase thrust significantly.
2. because of not having mechanical deceleration system and hydraulic machinery driving system, thereby can realize the synchro control and the control of selectivity permutation and combination of many linear electric motors, reaching the optimum matching of load and required horsepower output, energy savings, and can realize operating dynamical equilibrium substantially.
3. there are not mechanical retarder and rack-and-gear transmission, hydraulic machinery driving device, promptly there is not switching mechanism, transmission efficiency is 1, and makes that overall structure is simple, pulse free load, friction, noiseless, in light weight, easy-maintaining, operates steadily, and has improved running quality and has reduced service expenditure.
4. owing to be that non-adhesion drives,, also can carry out high low-speed running even adhere to greasy dirt on the secondary conductor so the kinetoplast quality can be made small and exquisitely.Linear electric motors are epoxy resin molded product, so, moisture resistance, antivibration, strong, the electric reliability height of corrosion stability, so need not often safeguard.
5. control circuit preceence simple, the running operation performance is as follows:
1. can carry out many linear electric motors synchro control and selectivity combination synchro control, be quick on the draw.
2. in given scope, can free adjustment thrust.
3. can obtain the identical thrust of advancing, retreating.
4. if the design speed controllable function, can adopt the speed control method of silicon control regulating voltage, thereby not have noise, need not fuel feeding, contact pointless, need not safeguard.
6. building ground, the harsh environment that dust etc. pollute and use under water especially aptly.Also be suitable for and make goods transport and personnel transport elevator.

Below in conjunction with accompanying drawing the utility model is described in further detail: embodiment one, single cage-lifter.
Enforcement two, double-cage elevator
Two cages 8 are connected by steel rope 2 with two counterweight iron 4a, 4b respectively, be suspended in derrick 12 each opposite flank that the stack of derrick joint (see figure 7) forms each other laterally by head sheave 1 before.The counterweight iron 4 of present embodiment by about two counterweight iron 4a form with the 4b bolt together, the elementary 3 one-tenth symmetries of linear electric motors install in it relatively.The secondary 5 material steel plates of the linear electric motors of four sides on the derrick 12, it places between two linear electric motors elementary 3, and linear electric motors secondary 5 are vertically mounted on the respective side of derrick 12.Make the material of linear electric motors secondary 5 with steel plate, then must use linear electric motors in pairs, and two linear electric motors symmetries are installed relatively, promptly linear electric motors elementary 3 in secondary 5 both sides of linear electric motors relatively symmetry install.By 13 whiles and the channled rail 14 and secondary 5 closed contacts of linear electric motors that are installed on the derrick 12 of the track adjusting wheel on counterweight iron 4a, the 4b, keeping the linear electric motors elementary 3 and the gap delta of linear electric motors secondary 5 is 1-2mm, and makes counterweight iron 4a, 4b lifting normal simultaneously.The first line 3 of cage 8 interior lines motors is to become the relative installation of symmetry, and linear electric motors secondary 5 place therebetween, by the column closed contact on track adjusting wheel on the cage 87 and the derrick 12, keep the gap delta of linear electric motors elementary 3 and secondary 5, and make cage 8 upper and lower normal operations.R is with single cage-lifter.Equally, double-cage elevator linear electric motors are secondary also can adopt aluminium sheet or copper coin or bimetallic plates.Steel rope balancer 6 is to change the device of receiving rope or putting rope according to adjustable height, and guide frame 10 is installed on the cage 8, and track adjusting wheel 7 is equipped with in configuration on it, and safe fence 15 is to prevent that personnel from entering the safety barrier in place when elevator is worked.
Adopt linear electric motors to drag and to be provided with single-phase loss protecting function, never allow single-phase dragging.
This electromagnetic lifter can be used as building operation elevator, high-power little speed or medium velocity elevator, high-rise higher speed elevator, under-water operation elevator, every field elevators such as balcony lift and goods, the defeated elevator of passenger traffic.
