Be elaborated below in conjunction with the principle of work of a specific embodiment to variable counterweight hydraulic elevator of the present invention.
Present embodiment is 15 layers with the lifting floor, and load carrying ability is that the elevator of 1000kg is an example, according to clump weight piece is set and counts formula: N=Wp/100kg, and wherein, Wp is the elevator nominal payload, unit is kg.And counterweight is regulated the number formula that manipulator is provided with: G=F-1, wherein F is total number of plies of elevator lifting.The clump weight quantity that present embodiment is selected for use is the 1000kg/100kg=10 piece, and every clump weight weight is 200kg; Counterweight is regulated manipulator and is provided with 14 layers, 10 groups every layer.
When lift car 2 not when carrying or goods, and when being in extreme lower position, this moment hydraulic actuating cylinder 11 piston 12 tops and the clump weight 6 that is arranged on the counterweight carriage 15 all be in the extreme higher position.When in the car 2 passenger or goods being arranged, recording weight as weight sensor 8 is 500kg, then the 2000kg weight of explanation balance weight this moment is bigger than normal, and give control setup 9 with the data of weight 500kg, drawing after control setup 9 computings needs counterweight minimizing 1000kg to mate the most, these timed unit 9 output control commands make through control circuit regulates electromagnetic valve 10 energisings that manipulator 7 links to each other with counterweight topmost, and then the execution finger of five deployings of the superiors readjustment joint manipulator 7 stretches out five clump weights 6 of the superiors that are installed, all the other clump weights 6 move downwards with counterweight carriage 15 and piston 12, upwards operation of car 2.
When car 2 runs to certain one deck, passengers or goods change and when reducing in the car 2, if the weight that this moment, weight sensor 8 recorded is 300kg, then the quality of explanation balance weight this moment still is bigger than normal, give control setup 9 with this data transmission then, after computing, need counterweight to reduce 600kg and mate the most.Control setup 9 output control commands are given through control circuit and are made three electromagnetic valves of the 6th, seven, eight rows 10 of this layer switch on, the execution finger of corresponding three deployings readjustment joint manipulator 7 stretches out and blocks corresponding three deploying pouring weights 6 under the driving of electromagnetic valve, all the other clump weights 6 move downwards with counterweight carriage 15 and piston rod 12, car 2 continues upwards operation, runs to top layer up to car 2.When car 2 moves downwards from the extreme higher position, no matter whether car 2 and the passenger in it or the total weight of goods and the weight of balance weight mate, when the piston stroking upward of hydraulic actuating cylinder, the clump weight 6 that all will stay each layer rises to the extreme higher position, and the execution finger that each counterweight adjusting manipulator 7 stretches out in its process pushes back the original place by clump weight 6.Here be noted that: it is that pneumatic extrusion or hydraulic pressure extrude in short-term that electromagnetic valve 10 stretches out at the described execution finger of driving, all the other times promptly are in unimpeded state for no air pressure or hydraulic pressure, because carrying out the end of finger is wedge shape, after it blocks described clump weight 6, clump weight just can not come off, when the piston 12 of hydraulic actuating cylinder 11 is up, when electromagnetic valve 10 is in the state of no air pressure or hydraulic pressure, carry out finger and can be easy to homing, throw off clump weight.
Enter the passenger of car 2 or gravitional force that goods had in the descending process of elevator all changes the clump weight 6 that each layer stayed into and promotes required potential energy from most significant bit or all the other positions.
In running process of elevator and under the out-of-work situation, when the oil cylinder of hydraulic actuating cylinder 11 breaks or hoist ropes 14 ruptures, piston 132 in the hydraulic pressure fall arrest safety tongs 13 elasticity hydraulic pressure output cylinders 133 under spring 131 effect to pressing down with the hydraulic oil of certain pressure expansive force oil cylinder 136 through the anti-fall safety tongs 13 of transport pipe 134 input hydraulic pressures, make the jaw 135 of the anti-fall safety tongs 13 of hydraulic pressure hold the steel rope of cable wire track tightly and car can't be dropped, and then guaranteed the safety of elevator operation.
The principle of work of variable counterweight elevator is with the principle of work of above-mentioned described variable counterweight hydraulic elevator.
Variable counterweight elevator of the present invention and hydraulic elevator are regulated manipulator by counterweight is set, and a plurality of clump weights are arranged in balance weight, and elevator can be according to the load carrying ability automatically regulating balance weight of car in the process of using.The present invention has effectively reduced the energy consumption of elevator, reaches the purpose of energy-saving low-carbon operation.In addition, the present invention also is provided with the fall arrest safety system, can not occur rushing to summit, weighing down phenomenons such as the end, hypervelocity and coaster in running process of elevator, particularly described variable counterweight hydraulic elevator can not have under the situation of electricity at main power source, can move by the standby control power supply of low capacity yet.
More than; only be preferred embodiment of the present invention, but protection scope of the present invention is not limited thereto, anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
