Embodiment Construction

[0024] Such as Figure 5A As shown, a linear motor arrangement method for a cordless elevator includes two "U"-shaped linear motors and a car 4, a "U"-shaped beam 6 is installed on the installation foundation 3, and the motor stator part 1 is fixed on the "U" The two sides of the inner wall of the "shaped beam 6, and the motor mover part 2 form a bilateral structure "U" type linear motor. The motor mover part 2 is connected with the car 4 through a connecting mechanism 5, constituting the moving part of the cordless elevator. The openings of the two "U"-shaped linear motors are arranged face to face, that is, the angle between the axes of the two "U"-shaped linear motors is 0°, as Figure 6A shown.

[0025] Such as Figure 5B As shown, the two "U" linear motors are arranged back to back, and the other structures are the same Figure 5A . The included angle between the axes of two "U" type linear motors is a is 180°, such as Figure 6C shown.

Abstract

The invention discloses a liner motor arranging method for a cordless elevator. Two U-shaped liner motors with bilateral structures are used as drive sources of an elevator and arranged at one side or two sides of a car to form a cordless elevator in a knapsack type or balance type structure. An included angle between the axes of the two U-shaped liner motors can be any angle between 0 degree and 360 degrees, and upper and lower air gaps of the U-shaped liner motors have the formula that g1 is smaller than or equal to g2. By adopting the motor arranging method provided by the invention, the double U-shaped permanent magnet liner motors inhibit normal attraction borne by the moving part of the elevator, reduce the mechanical strength of an installation base, a car and a positioning and braking device of the cordless elevator and the weight of the moving part of the elevator and increase effective loads. In addition, a smaller part of unbalanced normal attraction can be retained, the problem of side inclination of the knapsack type car can be effectively solved, and the stability of the air gaps in the running process of the motors can be kept.

Description

technical field [0001] The invention belongs to the field of cordless lifting, and in particular relates to a method for arranging a linear motor for a cordless elevator. Background technique [0002] Elevator or hoist is an important transportation link in mines and various buildings. In ordinary hoisting systems, the hoisting method is well known. The structure used by the hoist is that the mechanical room is installed on the upper part of the hoist, and the rotating motor drives the roller, winding The wire rope on the drum is connected to the car at one end and to a counterweight at the other end. However, for ultra-high buildings and ultra-deep mines with a large number of people and heavy loads, a high level of traffic handling capacity is required, and hoists occupy a large amount of building space and low transport capacity is a serious problem. [0003] In order to overcome the above-mentioned problems, a cordless linear motor hoist that does not require a wire rop...
