Description

folding barrier

technical field

The invention relates to a barrier gate.

Background technique

Existing barrier devices are all composed of a barrier with a driving mechanism and a brake lever driven by the barrier. As shown in Figure 1, the Chinese patent announcement number CN 204000680 U provides an advertising road Gate, its lifting drive mechanism 2' is set in the chassis 1', the outer end of the upper stop rod 3' and the lower stop rod 4' are connected by the bracket 6, and the two ends of the connecting rod 5 are connected with the inner end of the lower stop rod 4' and the chassis respectively. 1' is hinged, and the advertising blade 7 is set between the upper bar 3' and the lower bar 4'. When the lifting drive mechanism 2' in the chassis 1' drives the upper bar 3' to rise, the upper bar 3' passes through The bracket 6 drives the lower bar 4' to turn upwards with the hinge point of the connecting rod 5 and the chassis 1' as the center of the circle. This kind of gate structure uses the upper bar 3' as the active bar, and the upper bar 3' is driven by the bracket 6. The lower lever 4' rises and falls, and the upper lever 3' swings up and down mainly by the driving action of the lifting drive mechanism 2'. The upper lever is frequently stressed and wears for a long time, so it is prone to failure and shortens its service life. , The failure rate of traditional barrier devices like this is high, and safe use cannot be guaranteed.

Compared with the existing barrier gate It is much more reliable and firmer to lift the lower gear lever through the upper gear lever.

2. The present invention adopts the upper crossbar, the lower crossbar and multiple connecting rods vertically and parallelly connected between them. Compared with the traditional single-bar structure, its structure is stable and reliable, and it is not easy to be shaken by the wind and has good stability. It has good wind resistance and effectively guarantees its service life.

detailed description

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

Example

As shown in Figure 2 and Figure 3, the foldable barrier gate includes a barrier gate case 1 with a square frame, an upper cross bar 2, a lower cross bar 3, a plurality of parallel connecting rods 4 and a driving device;

The gate chassis 1 is welded into a square frame of the gate chassis 1 by a plurality of horizontal or vertical frame bars, and one end of the upper cross bar 2 is connected to the top frame bar 11 of the square frame by pins, and a plurality of connecting rods 4 are spaced apart by pins. Connected between the upper cross bar 2 and the lower cross bar 3;

One end of the lower cross bar 3 is slidably connected to the lower end of the barrier gate chassis 1, and the driving device touches the sliding end of the lower cross bar 3 to push the lower cross bar 3 to slide up and down on the vertical plane, thereby driving the upper cross bar 2 to rotate on the vertical plane .

The driving device includes a push rod motor 51 installed in the barrier gate cabinet 1, a pair of drive rods 52 and a horizontal slide rod 53 arranged below the push rod motor 51, the push rod motor 51 is arranged in the vertical direction, and the push rod motor The push rod 54 of 51 faces downward, and the sliding rod 53 passes through the sliding end of the lower cross bar 3 to form a rotational connection with the lower cross bar 3. In the vertical chute; one end of the two drive rods 52 is connected to one of the vertical frame bars of the barrier gate cabinet 1 by a pin, and the middle part of the two drive rods 52 is interconnected by a connecting rod, which is connected to the push rod in rotation. The end of the push rod 54 of the motor 51 and the other ends of the two driving rods 52 clamp the sliding ends of the lower cross bar 3 in the middle, and both of them abut against the bottom of the sliding rod 53 .

The working principle of the barrier gate of the present invention is as follows: when the brake lever is to be raised to release the vehicle, the push rod 54 of the push rod motor 51 rises, driving the two driving rods 52 to rotate counterclockwise, because the ends of the driving rods 52 are against the sliding rod 53, the driving rod 52 pushes the sliding rod 53 at the same time during the rotation, so that the two ends of the sliding rod 53 slide upward along the vertical chute of the vertical frame bar 12 on both sides, and the sliding rod 53 also drives the lower horizontal when sliding upward. The rod 3 is lifted upwards, and the upper cross bar 2 is turned upward through the connecting rod 4 connected to it. A plurality of vertically parallel connecting rods 4 are hinged between the upper cross bar 2 and the lower cross bar 3, and are articulated using the parallelogram principle. , when the upper cross bar 2 and the lower cross bar 3 rotate upwards to upright, a compressed state is formed between a plurality of connecting rods 4; Rotate downward with lower cross bar 3, carry out opposite motion process.

In the present invention, the lower cross bar 3 is used as the active rod, and the upper cross bar 2 is driven to rise and fall by the connecting rod 4, and the lower cross bar 3 is hinged with a sliding rod 53, and the two ends of the sliding rod 53 are connected between two driving rods 52. Can move up and down respectively along the vertical chute on both sides under the pushing action of the push rod, so it can be seen that in fact, the hinge point of the motor push rod and the sliding points at both ends of the slide rod form a stable relationship of a triangle together, and the slide rod 53 is in the The lower cross bar 3 is used to lift the upper cross bar 2 below. Compared with the way that the existing barrier gate lifts the lower bar through the upper bar, the force bearing method is more ideal, and the transmission mode is more firm and reliable.
