This scheme discloses an adopt sucking disc device to improve elevator security performance's scheme, with the rear of original elevator vacuum chuck in addition, be furnished with the vacuum pump in the car top, thereby let vacuum chuck firmly hold the car through control vacuum pump when the elevator stops, promote security performance. The traction transmission relation of the traction type elevator is that a motor combined reducer, a brake and the like which are arranged in a machine room form a traction machine, a traction steel wire rope is connected with a lift car and a counterweight through a traction sheave, and the traction steel wire rope is tightly pressed in a rope groove of the traction sheave by the gravity of the lift car and the counterweight device. When the traction motor drives the traction sheave to rotate, the friction force between the steel wire rope and the rope groove of the traction sheave drags the lift car and the counterweight to reciprocate in the hoistway along the guide rail through the steel wire rope, and the function of the elevator is realized.
The movement of the car and the counterweight is achieved by means of friction between the traction rope and the traction sheave, which is called traction force. For the elevator to operate, the traction force T must be greater than or equal to the difference between the larger load force T1 and the smaller load force T2 in the hoisting ropes, i.e. T.gtoreq.T 1-T2. When the elevator is running, the load is varied, ranging between empty and full car. Because the self weight of the car and the counterweight are constant, the tension T1 and T2 of the steel wire ropes on two sides of the traction sheave changes along with the change of the load, and the change has three conditions that the car is heavier than the counterweight side (T1> T2), the car side is equal to the counterweight side (T1 is equal to T2), and the counterweight side is heavier than the car (T2> T1). When T1 is T2, the loads on both sides of the traction sheave are equal, and there is no friction between the traction sheave and the wire rope, which is the optimum condition for elevator operation. When T1> T2 or T1 < T2 is equal to the weight of the car or the weight of the car is light, if the car and the counterweight are kept relatively static, the static friction force F generated between the traction sheave and the steel wire rope prevents the relative sliding between the weight side and the car side, and the balance between T1 and T2 is kept. If the motor drives the traction sheave to rotate, the steel wire rope is attached to the traction sheave groove to rotate together with the traction sheave under the action of static friction force, so that the lift car and the counterweight move up and down along with the steel wire rope, namely the traction drive, which is a friction traction form realized by the static friction force between a flexible body and a rigid body.
As can be seen from the above, when T1 < T2 is equal to the weight of the car or the weight of the car, the friction force generated between the traction sheave and the wire rope is reduced by the oil on the traction sheave. In the physical definition, the maximum friction force is generated when two contact objects are in a critical state to slide but not slide, and is opposite to the direction of the force tending to move the objects, and the magnitude of the friction force is proportional to the magnitude of positive pressure (namely, normal counter force) N between the two objects, namely, Fmax ═ μ. After the elevator is stained with engine oil, the size of FN is unchanged, the numerical value of mu is reduced, the value of Fmax is reduced, T1 is less than T2, and T1+ Fmax is equal to T2, when the value of Fmax is reduced, T1+ Fmax is less than T2, the resultant force of T1 and Fmax and T2 cannot be balanced, the elevator is unbalanced in stress and moves upwards, and casualty accidents are caused.
Vacuum suction cups, also known as vacuum spreaders and vacuum nozzles, are generally the least expensive method to use. The vacuum chuck is one of vacuum equipment actuators, and the chuck is made of nitrile rubber and has larger breaking force, so the vacuum chuck is widely applied to various vacuum holding equipment, such as in the industries of buildings, paper making, printing, glass and the like. The application in tunnel construction is also mature. The structure of the sucking disc is shown in figure 2 and consists of a sucking disc mouth and a sucking disc hoop body. The vacuum sucker is communicated with vacuum equipment (such as a vacuum generator and the like) through a connecting pipe, then is contacted with an object to be lifted, the vacuum equipment is started to suck, negative air pressure is generated in the sucker, and therefore the object to be lifted is firmly sucked, and the object to be lifted can be carried. When the object to be lifted is conveyed to a destination, the air is stably inflated into the vacuum chuck, so that the negative air pressure in the vacuum chuck is changed into zero air pressure or slightly positive air pressure, the vacuum chuck is separated from the object to be lifted, and the task of lifting and conveying the object is completed.
Generally, in order to prevent the surface of the product from being scratched, it is preferable to select a sucker chuck material with bellows made of nitrile rubber or silicone rubber, which is made of nitrile rubber and has a large breaking force, and thus is widely used in various vacuum holding apparatuses. The nitrile rubber is prepared from butadiene and acrylonitrile by an emulsion polymerization method, is mainly produced by a low-temperature emulsion polymerization method, and has the advantages of excellent oil resistance, higher wear resistance and better heat resistance. The nitrile rubber is mainly used for manufacturing oil-resistant rubber products. The acrylonitrile-butadiene rubber contains 42-46% acrylonitrile, 36-41% acrylonitrile, 31-35% acrylonitrile, 25-30% acrylonitrile, 18-24% acrylonitrile and the like. The more the acrylonitrile content, the better the oil resistance. It can be used in 120 deg.C air or 150 deg.C oil for a long period. In addition, it has excellent water resistance, air tightness and excellent adhesion performance. It is widely used for preparing various oil-resistant rubber products. Therefore, the suction cup adopting nitrile rubber has the following advantages: the rubber has the advantages that the rubber is endowed with better physical mechanical property and wear resistance through reinforcement; when the content of acrylonitrile butadiene rubber acrylonitrile is 39%, the airtightness is equivalent to that of IIR rubber, and the airtightness is good; the flexibility is common at low temperature; fourthly, the antistatic performance is excellent; the effect of plasticizing by using polar lipids is better.
The powerful adsorption affinity that this scheme utilization vacuum chuck produced makes the elevator can firmly adsorb at the well inner wall when stopping corresponding floor, increases the resultant force on the steel wire of connecting this limit of car and makes the car not rise. Meanwhile, a vacuum pump is used for extracting and charging air, the specific principle is that a motor makes circular motion, a diaphragm inside the pump makes reciprocating motion through a mechanical device, so that air in a pump cavity with a fixed volume is compressed and stretched to form vacuum negative pressure, pressure difference is generated between the position of a pump air inlet and the external atmospheric pressure, and air pressure is sucked into the pump cavity and then discharged from an air outlet under the action of the pressure difference. Wherein the small vacuum pump is suitable for occasions requiring long-term idling, dry running and the like, and the small vacuum pump can achieve the effect only by being suitable in number (according to the loading capacity of a specific elevator and the surface condition of the inner wall of a well). An infrared transmitting device is installed above the elevator car door, an infrared receiving device is also installed inside a shaft at the corresponding position of the infrared transmitting device, when the elevator stops at a target floor, the infrared sensing devices at two sides of the upper part are in butt joint, and control information is sent to the air pump through the central processing unit to enable the air pump to evacuate air in the suction cup, so that the inside of the suction cup is in a vacuum state, and the effect of fixing the elevator is achieved. Therefore, the scheme has the following characteristics: the electromagnetic suction disc has the advantages that the electromagnetic suction disc is easy to use, and can be used on steel products and cannot be used on plates or objects made of other materials as long as the electromagnetic suction disc can be sealed and does not leak air; the vacuum chuck is environment-friendly, does not pollute the environment, and does not generate light, heat, electromagnetism and the like; the workpiece is not damaged, the vacuum chuck is made of rubber materials, the workpiece cannot be damaged when being sucked or put down, and the hook type lifting appliance and the steel cable type lifting appliance cannot be used. Based on the characteristics, compared with the prior art, the elevator system with the sucker safety device has prominent substantive characteristics and remarkable progress.
