Description

M247612 V. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to a braking device, especially a two-way braking device using a ratchet, that is, it can stop regardless of clockwise or counterclockwise rotation. It can be applied to the device of the gate switch, so that different rotation directions can be controlled during manual input, such as rising and / or lowering, but when the manual is not input, the gate can be stopped. [Previous technology]

The conventional gate opening device must have both an electric drive device and a manual drive device to ensure that the manual drive device can be used as a power source in the event of a power outage or electrical machinery failure, and the gate opening or closing operation can be performed. Generally, in such a gate opening device, a clutch or a two-way driving connection structure is required to connect two power input devices to another power output device through a mechanism to achieve power transmission. Referring to the first figure A, it is mainly a differential gear set A installed in the gate opening device, and thereby an electric input device 2 and a manual input device 3 are connected to an output transmission device 4 to achieve two The power input device (such as 2, 3) is connected to another power output device (such as 4) by a mechanism at the same time. Among them, in order to reduce the speed, a worm reducer 5 is connected near the manual input device 3 to save the manual input force.

At present, in the conventional gate opening device, only the worm gear reducer 5 is used to “amplify” the force and provide a brake control device. However, the worm gear reducer 5 series has a limited function of braking, that is, when the reduction ratio reaches a certain level, it is only available. Brake function. Moreover, the cost of the worm reducer 5 is expensive. Generally speaking,

Therefore, it cannot provide effective bidirectional control (reversible clockwise or clockwise rotation). [New content] _ In order to provide a braking device that can achieve bidirectional control, this creation provides a two-way braking device, including: a first ratchet and a first-second ratchet, each with several braking parts, and the first The braking directions of the ratchet wheel and the second ratchet wheel are opposite to each other.

For three. During actual operation, please refer to the top view of the fourth figure. When stationary, the brake pads 14 abut against the braking portion 1 10 of the first ratchet wheel 11 and the braking portion 12 of the second ratchet wheel 12 respectively. Please refer to the fifth figure. When the two-way controller 1 3 rotates in the direction of the arrow A 1, the arc convex portion 1 3 1 can abut the brake pad 1 1 of the first ratchet 1 1 braking portion 1 1 0. Pushing outward, the first ratchet wheel 11 and the second ratchet wheel 12 can be rotated in the direction of the arrow A1 at the same time. When stopped, the two-way controller 1 3 returns to the original position, and the brake pads 1 4 can be applied on both sides.

M247612 V. Creation instructions (4) The force (such as the direction of arrow B), and the restoring force of the spring 1 3 3 makes it return to the stationary state of the fourth picture. Similarly, referring to the sixth figure, when the two-way controller 1 3 rotates in the direction of the arrow A 2, the arc convex portion 1 3 1 can brake the second ratchet wheel 12 and the braking portion 1 2 0. The block 14 is pushed outward, so that the first ratchet wheel 11 and the second ratchet wheel 12 can be rotated in the direction of the arrow A 2 at the same time. When stopped, the two-way controller 13 returns to its original position, and external forces (such as the direction of arrow B) can be applied to both sides of the brake pads 14 and restored to the fourth position by the restoring force of the spring 1 3 3 Illustration of a stationary state.
