Description

Electromagnetic clamping mechanism of elevator

Technical Field

The utility model belongs to the technical field of elevators, relates to a flat bed locking mechanism, and particularly relates to an electromagnetic clamping mechanism of an elevator.

Background

The development of elevators is in a peak state. Most manufacturers or individuals have chosen more multi-story buildings in order to increase the utilization of the field, and therefore a device is also needed to facilitate the lifting and lowering of goods. Since the conventional elevator has high cost and low bearing capacity and is not suitable for loading tens of tons or hundreds of tons of goods, a hydraulic elevator with high bearing capacity is developed to assist in production and transportation of goods. The elevator is safe, has an ultra-large load capacity, is convenient to maintain, and enables the special industry to develop more quickly.

The leveling device of the elevator is generally a magnetic switch, a photoelectric inductive switch and the like which are combined with a reed switch for use, and the aim of stabilizing the leveling is achieved by combining a control system and software which are edited by a certain algorithm. However, if a heavy load or a large wave of passengers get in and out of the car after the elevator is stopped at a predetermined position, the wire rope suspending the car may be greatly fluctuated or shaken up and down due to a great change in the overall weight of the car. Therefore, the height difference between the inner surface of the car and the floor surface is increased in the process of getting in and out the car for goods or passengers. Such jitter or undulations do not cause discomfort to most passengers, but can cause jams, jolts, etc. in and out of the cars of a cart pulling cargo. If the automatic control carrier carrying heavy and falling goods is used for entering and leaving, the problems that the carrier is blocked at an elevator port and cannot enter, the center of gravity of the goods shifts, the goods are bumpy and cracked and the like can occur.

The stopper is important safety device in the lift, avoids quick rising or quick descending of lift when the operation, has ensured operation safety. At present, a limiter adopted by an elevator mainly comprises a fence door limit, a cage door limit, a top door limit, a limit switch, an upper limit switch, a lower limit switch, a counterweight anti-rope-breakage protection switch and the like. The existing lifting stabilizing mechanism is realized by mainly adopting a mode of directly cutting off a power supply by a proximity switch and controlling a motor to stop. However, these stoppers are also only configured to stop the elevator from moving up and down to a large extent, and cannot avoid shaking or vibration caused by heavy loads or large passengers getting in and out of the car after the elevator stops moving up or down.

In the prior art, a parking robot is used for transporting vehicles such as cars in and out of a lift, so that the purposes of automatic parking and taking of the vehicles in a multi-story building are achieved. However, parking robots require full or partial reach into the vehicle bottom, usually using wheels with a small diameter, while the weight of the vehicles to be transported is mostly 2-5 tons. When the parking robot carries the vehicle, the parking robot is not suitable for passing the threshold and crossing the ditch, when the height of the threshold is larger and the width of the ditch is larger, the wheels of the parking robot are easy to be clamped and cannot move, and the carried vehicle is likely to deviate or bump.

SUMMERY OF THE UTILITY MODEL

In view of the above-mentioned technical problems in the prior art, an object of the present invention is to provide an electromagnetic clamping mechanism, which can clamp and fix the car of an elevator after the elevator stops at a certain floor position, so as to solve the problem of the shaking caused by the heavy goods or large passengers entering and exiting the car.

The technical scheme adopted by the utility model is as follows:

an elevator electromagnetic clamping mechanism 1 includes a fixed portion and a movable portion. The fixed part comprises an adsorption plate 2, the adsorption plate 2 is fixed on a frame 14 corresponding to the side surface of the elevator car 13, and a limiting hole 3 is formed in the adsorption plate. The movable part is fixedly mounted on the side of the elevator car 13 and comprises a support 4, which support 4 comprises a front connecting plate 5 and a rear connecting plate 6 parallel to each other, and a plurality of connecting rods 7 for fixedly connecting the front connecting plate 5 and the rear connecting plate 6. The movable part is including being located inside and mobilizable flaky magnet fixing base 8 of support 4, magnet fixing base 8 is equipped with first electro-magnet 9 towards one side of back connecting plate 6, magnet fixing base 8 is equipped with second electro-magnet 10 and the stopper 11 that suits with the shape of spacing hole 3 towards one side of preceding connecting plate 5 to be equipped with the trompil that can hold second electro-magnet 10 and stopper 11 on the preceding connecting plate 5.

Furthermore, a positioning column 12 for determining the installation position is arranged on the outer side of the rear connecting plate 6.

Further, the adsorption plate 2 needs to be installed at each position where the elevator car needs to be stopped. In this way the elevator car 13 can be clamped in every position where it is to be stopped, preventing heavy loads or large passengers from bouncing in and out of the car.

Further, a plurality of the electromagnetic clamping mechanisms 1 may be mounted on one elevator car 13. The larger the number of the electromagnetic clamping mechanisms 1 installed, the more remarkable the clamping effect on the elevator car 13 and the larger the load bearing.

Further, the plurality of electromagnetic clamping mechanisms 1 on one elevator car 13 are preferably symmetrically mounted.

The electromagnetic clamping mechanism of the elevator comprises two electromagnets, a first electromagnet 9 and a second electromagnet 10, wherein the two electromagnets are important parts for enabling the electromagnetic clamping mechanism to achieve the purpose of fixing the car. When the first electromagnet 9 is energized and the second electromagnet 10 is de-energized, the magnet holder 8 and other components of the load are attracted to the rear connecting plate 6, i.e. close to the elevator car 13, by the magnetic force of the first electromagnet 9. The second electromagnet 10 and the limiting block 11 are also close to the elevator car 13 and far away from the adsorption plate 2 fixed on the frame 14 corresponding to the side surface of the elevator car 13, so that the limiting block 11 is separated from the limiting hole 3 of the adsorption plate 2. At this time, the elevator car 13 can be freely raised and lowered. When the first electromagnet 9 is de-energized and the second electromagnet 10 is energized, the magnet holder 8 and other components of the load are attracted to the front connection plate 5, i.e. away from the elevator car 13, by the magnetic force of the second electromagnet 10. The second electromagnet 10 and the limiting block 11 are also away from the elevator car 13 and close to the adsorption plate 2 fixed on the frame 14 corresponding to the side of the elevator car 13, so that the limiting block 11 is inserted into the limiting hole 3 of the adsorption plate 2. At this moment, because of the spacing effect of the limiting block 11, the elevator car 13 is fixed at the current position, and cannot move up and down, so that shaking caused by heavy goods or large-wave passengers entering and exiting the car is avoided to the maximum extent.

The utility model has the following beneficial effects;

1. the electromagnetic clamping mechanism of the elevator has the advantages of simple structure, convenient installation and obvious clamping effect;

2. after the electromagnetic clamping mechanism is started, the elevator provided with the electromagnetic clamping mechanism can be firmly fixed under the matching of the plurality of limiting blocks and the limiting holes, when heavy goods or large-wave passengers enter and exit the lift car, the elevator cannot shake due to the change of the weight of the lift car, so that a large height difference is generated between the inner surface of the lift car and the floor, and the automatic carrier provided with the heavy goods and smaller wheels is clamped;

3. the elevator clamping mechanism adopts an electromagnet and can be automatically controlled.
