Detailed description of the invention
Fig. 1 is the present invention schematic diagram electrically jointly controlling brakes for commercial car lift bridge。Structure is known as shown in Figure 1, this kind includes by carrying air bag 1 for the brakes that electrically jointly controls of commercial car lift bridge, promote air bag 2, suspension gas receiver 4, 3 position-5 way electromagnetic valve 6, air bag relay valve 7, pressure regulator valve 9, the elevating control gas circuit of switch 10 and two-bit triplet electromagnetic valve 11 composition, and by brake chamber 3, row vehicle air reservoir 5, braking relay valve 8, the control for brake gas circuit of switch 10 and two-bit triplet electromagnetic valve 11 composition, described carrying air bag 1 is connected with air bag relay valve 7, air bag relay valve 7 separates two branch roads, article one, branch road is connected with suspension gas receiver 4, another branch road passes sequentially through 3 position-5 way electromagnetic valve 6 and pressure regulator valve 9 is connected with suspension gas receiver 4, lifting air bag 2 also passes sequentially through 3 position-5 way electromagnetic valve 6 and pressure regulator valve 9 is connected with suspension gas receiver 4；Brake chamber 3 is connected with braking relay valve 8, and braking relay valve 8 also separates two branch roads, and a branch road is directly connected with row vehicle air reservoir 5, and another branch road is connected with braking foot valve epicoele by two-bit triplet electromagnetic valve 11；Described 3 position-5 way electromagnetic valve 6 and two-bit triplet electromagnetic valve 11 are connected to switch 10。
Switch 10 is rocker switch, controls the rising of lift bridge and moves down, and making two states interlock。
The work process of elevating control gas circuit is: when lift bridge promotes, and gases at high pressure inflate to lifting air bag 2 by 3 position-5 way electromagnetic valve 6, and carrying air bag 1 is exitted to air by air bag relay valve 7；When lift bridge declines carrying, gases at high pressure are inflated to carrying air bag 1 by air bag relay valve 7, promote air bag 2 and are exitted to air by 3 position-5 way electromagnetic valve 6, switch the rising of 10 control lift bridges and move down, and making two states interlock。
The work process of control for brake gas circuit is: two-bit triplet electromagnetic valve 11 controls braking relay valve 8 break-make gas according to the signal of telecommunication of switch 10, and when the D mouth of braking relay valve 8 has gas, the braking A mouth of relay valve 8 connects with B mouth, brake chamber 3 inflation braking；The D mouth of braking relay valve 8 does not have gas, and the braking A mouth of relay valve 8 disconnects with B mouth, brake release；When the D mouth of braking relay valve 8 does not have gas, lift bridge brakeless。
As shown in Figure of description 1, acquiescence is now original state, and the gases at high pressure in suspension gas receiver 4 are arrived the P mouth of 3 position-5 way electromagnetic valve 6 by pressure regulator valve 9。When pressing switch 10 to lifting state, 3 position-5 way electromagnetic valve 6 spool moves down, and the P mouth of 3 position-5 way electromagnetic valve 6 connects with B mouth, inflates to lifting air bag 2, and lift bridge promotes；The A mouth of 3 position-5 way electromagnetic valve 6 connects with R mouth, the air bag logical air of the D mouth of relay valve 7, and the A mouth of air bag relay valve 7 and B mouth are off, and the C mouth of relay valve 7 leads to air, and in carrying air bag 1, gas passes through air bag with the C mouth of relay valve 7 discharged to air。
When switch 10 is pressed to loaded state, 3 position-5 way electromagnetic valve 6 spool moves, the P mouth of 3 position-5 way electromagnetic valve 6 connects with A mouth, the air bag D mouth of relay valve 7 is ventilated, the A mouth of air bag relay valve 7 and B mouth are in connected state, and the air bag C mouth of relay valve 7 is closed, and carrying air bag 1 starts inflation, lift bridge declines, and starts carrying；The B mouth of 3 position-5 way electromagnetic valve 6 connects with S mouth, promotes gas in air bag 2 and passes through 3 position-5 way electromagnetic valve 6 discharged to air。
Such as Fig. 1, when switching 10 by during to loaded state, two-bit triplet electromagnetic valve 11 spool moves down, and the A mouth of two-bit triplet electromagnetic valve 11 connects with B mouth。During braking, braking foot valve epicoele air-flow, by two-bit triplet electromagnetic valve 11, acts on the D mouth of braking relay valve 8, makes the A mouth of braking relay valve 8 connect with B mouth, braking is closed with the C mouth of relay valve 8, and driving gas receiver 5 inner high voltage gas is braked to brake chamber 3 inflation by braking relay valve 8；When brake release, braking is discharged by the D implication of relay valve 8, and the braking A mouth of relay valve 8 disconnects with B mouth, and the C mouth of braking relay valve 8 is opened, and gas indoor gas is by braking with the C mouth of relay valve 8 discharged to air, brake release。
When switch 10 by lifting state time, two-bit triplet electromagnetic valve 11 spool under spring force on be moved back into initial position。During braking, braking foot valve epicoele air-flow is unable to reach the D mouth of braking relay valve 8, and the braking A mouth of relay valve 8 disconnects with B mouth, and driving gas receiver 5 inner high voltage gas is unable to reach air chamber, and lift bridge is not braking。
There is this kind of said structure reliable, simple, pneumatic control system that cost is low for the lifting electrically jointly controlling brakes of commercial car lift bridge and braking, and ensure that lift bridge brakeless when the state of lifting, decline carrying time brake normally。
