Embodiment Construction

[0019] The technical solutions of the present invention will be further described below through specific embodiments.

[0020] During the movement of the frequency conversion torque barrier gate,

[0021] The moment of inertia formula of railing 4 is: J=1 / 3mL 2

[0022] The resultant moment formula is: M=J*β, where β is the angular acceleration,

[0023] The torque of the counterweight spring 5 during the movement is: Ms=K*L 2 *cos(δ+t)

[0024] The required torque of the railing 4 during the movement is: M l = 1 / 2Ml 1 cost

[0025] The motion process equation is: Ms+M motor +M l = M

[0026] That is, K*L 2 *cos(δ+t)+M motor +1 / 2Ml 1 cost=1 / 3mL 2 beta

[0027] It can be seen from the above formula that the gear reducer 2 is used, the resultant torque of the counterweight spring 5 torque, railing 4 static torque, and railing 4 running torque can be directly fed back to the drive motor 1, and the above equation can be established during the operation process. The ...

Abstract

The invention discloses a variable frequency torque floodgate, which comprises a gear reducer, a four-quadrant converter and a motor, wherein the gear reducer is used to directly feed back torque of a spring, static torque of a handrail, torque needed by operation of the handrail and torque signals to the motor, the four-quadrant converter calculates output torque of the motor and torque difference between a counter weight spring and the handrail according to resultant torque signals which are fed back, controls the motor to run in four quadrants according to a calculated result, controls the output torque of the motor, and guarantees different lifting and falling speed of the handrail, the motor is used to output torque needed by running of the handrail, and acts the torque onto a drive mechanism through the gear reducer, and the drive mechanism further drives the handrail to run. The variable frequency torque floodgate enables the lifting and the falling speed to be different, can meet high speed running, is safe at the same time, and can guarantee different lengths of handrails to be capable of using the same machine core.

Description

technical field [0001] The invention relates to the field of barrier gates, and more specifically, relates to a frequency-variable torque barrier gate that can make the speeds of lifting and lowering the poles different. Background technique [0002] Barrier gates are also called car stoppers, which are widely used in residential areas, shopping malls, expressways and other places where vehicles pass. With the development of commercial activities, barrier gates and railings are also used as carriers of print advertisements, and railings are damaged and replaced due to vehicle driving errors. However, due to the mechanical structure and control circuit design of traditional barrier gates, in The seemingly normal behavior of installing print advertisements on the railings or replacing the railings at will will seriously affect the balance system of the mechanical structure, aggravate the aging of the gate movement, and make the barriers scrapped in advance. [0003] At presen...
