Abstract
The invention provides a pneumatic door of an elevator. The pneumatic door comprises an elevator car (1), elevator doors (2), an air pump (3) and cylinders (4), wherein the elevator car (1) is fixedly provided with the air pump (3) and the cylinders (4); piston rods (41) of the two cylinders (4) are respectively fixed together with the two elevator doors (2); a loop, used for supplying air to the cylinders (4), of the air pump (3) is sequentially connected with a one-way valve (5), a buffer air tank (6), a throttling valve (7), a pressure relief valve (8) and an electromagnetic directional valve (9). The pneumatic door is simple in manufacturing, low in production cost, safe in use and convenient in maintenance and conservation.
Description
technical field:
The present invention relates to elevator technology field, more specifically to a kind of lift car pneumatic door device used.
background technology:
Traditional elevator door-motor is all by motor rotation, and moment motor being produced by frequency control and toothed belt transmission changes the power of a specific direction into, and by door control system realize gate, Room door linkage is open/close; This electric door machine, is the type of drive of having used till today since elevator comes out, and it exists complex structure, manufacture difficulty, involve great expense and the problem of poor safety performance.
summary of the invention:
Object of the present invention is exactly the deficiency for prior art, and a kind of elevator pneumatic door is provided, and it makes simple, and productive costs is low, uses safety, and maintenance is very convenient.
Technology solution of the present invention is as follows:
A kind of elevator pneumatic door, comprise lift car, elevator door, air pump and cylinder, on lift car, be fixed with air pump and cylinder, the piston rod of two cylinders is fixed together with two fan elevator doors respectively, on the confession air circuit of air pump to cylinder, is connected with check valve, buffering gas tank, flow regulating valve, reducing valve and solenoid directional control valve in turn.
The top of described lift car is fixed with air pump bracing frame, on air pump bracing frame, by screw, is fixed with air pump, and between the bottom of air pump and air pump bracing frame, to have cushion blocking, air pump be without oily quiet air pump in clamping.
On the front end of the piston rod of described cylinder, form step, the upper end of elevator door is welded with push pedal, in the default hole of the front end sleeve of piston rod in push pedal and the left surface and the nut that stretch out push pedal be screwed together, the right side of push pedal is pressed against on step.
Two limits of described reinforcement gusset are weldingly fixed on respectively on push pedal and elevator door.
The electric signal of the open/close door of original electric door machine is transferred to the solenoid directional control valve of the open/close door of existing control, to reach the object of the open/close door of follow procedure,
Beneficial effect of the present invention is:
1. with respect to traditional motor-driven door machine, the gyroscopic movement of motor is transformed into straight-line motion, the direct linear movement output of this pneumatic door machine, in structure, motor-driven is simple relatively, and manufacturing process is also relatively simple.
2. pneumatic door machine uses pneumatic transmission, is flexible thrust; Motor-driven door machine is rigidity thrust, and in safety, pneumatic door machine is also than motor-driven door machine safety.
3. what pneumatic door machine adopted is all general purpose accessory, all very convenient in the maintenance in later stage and maintenance
4. the manufacturing cost of pneumatic door machine is 1500 yuan/about cover, and the bid of electric door machine is in 3000 yuan/cover left and right, and every cover reduces costs 50% left and right, economic benefits.
accompanying drawing explanation:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that cylinder is connected with elevator door;
Fig. 3 is that air pump is to the air feed loop diagram of cylinder.
In figure: 1, lift car; 2, elevator door; 3, air pump; 4, cylinder; 41, piston rod; 411, step; 5, check valve; 6, buffering gas tank; 7, flow regulating valve; 8, reducing valve; 9, solenoid directional control valve; 10, air pump bracing frame; 11, cushion blocking; 21, push pedal; 12, nut; 13, strengthen gusset.
the specific embodiment:
Embodiment: see shown in Fig. 1 to 3, a kind of elevator pneumatic door, comprise lift car 1, elevator door 2, air pump 3 and cylinder 4, on lift car 1, be fixed with air pump 3 and cylinder 4, the piston rod 41 of two cylinders 4 is fixed together with two fan elevator doors 2 respectively, on the confession air circuit of air pump 3 to cylinder 4, is connected with check valve 5, buffering gas tank 6, flow regulating valve 7, reducing valve 8 and solenoid directional control valve 9 in turn.
The top of described lift car 1 is fixed with air pump bracing frame 10, on air pump bracing frame 10, by screw, is fixed with air pump 3, and between the bottom of air pump 3 and air pump bracing frame 10, to have cushion blocking 11, air pump 3 be without oily quiet air pump in clamping.
On the front end of the piston rod 41 of described cylinder 4, form step 411, the upper end of elevator door 2 is welded with push pedal 12, in the default hole of the front end sleeve of piston rod 41 in push pedal 12 and the left surface and the nut 13 that stretch out push pedal 12 be screwed together, the right side of push pedal 12 is pressed against on step 411.
Two limits of described reinforcement gusset 13 are weldingly fixed on respectively on push pedal 12 and elevator door 2.
Principle of work: elevator door 2 is connected with piston rod 41, in the stroke that opens the door, control housing is controlled for air circuit piston rod 41 is stretched out, and promotes elevator door 2 and opens; In the stroke of closing the door, for air circuit, piston rod 41 is regained, pulled elevator door 2 to close.The dynamics of opening the door of elevator door 2, can make step-less adjustment by pressure regulating valve 8; The speed of opening the door of elevator door 2, can make step-less adjustment by flow regulating valve 7;
Miniature without producing a small amount of water in oily quiet air pump, can be set in arbitrary time by time relay and electromagnetic valve and realize automatic-discharging.Less because of the water yield of its generation, enter in elevator hoistways and freely evaporate.The water outlet of air pump is connected with an electromagnetic valve, and this electromagnetic valve is connected with time relay.
