[0023] A vertical lifting entrance and exit weight detection device comprises a base 1, a mounting groove 7 is provided in the base 1, a mounting plate 8 is provided in the mounting groove 7, a plurality of groups of positioning columns 15 are movably inserted on the top of the mounting plate 8, a lower pressing plate 14 is fixedly installed on the upper end of the positioning column 15, a plurality of groups of tension springs 16 corresponding to the positioning column 15 are fixedly installed on the bottom of the mounting plate 8, the tension spring 16 is sleeved on the positioning column 15, a fixing ring 17 is fixedly installed on the lower end of the positioning column 15, the lower end of the tension spring 16 sleeve is fixedly installed on the top of the fixing ring 17, and a weighing sensor 18 for automobile weight detection is fixedly installed on the top of the mounting plate 8;

[0024] By setting the tension spring 16, after the car wheel passes the lower pressure plate 14, the tension spring 16 can pull the positioning column 15 through the fixing ring 17, so that the positioning column 15 pushes the lower pressure plate 14 when moving, so that the lower pressure plate 14 can return to its original position, so that the car can press the lower pressure plate 14 next time;

[0025] A plurality of columns 4 are arranged on the top of the base 1, a bearing frame 2 is arranged on the plurality of columns 4, and a bearing plate 3 for parking a car is fixedly mounted on the bearing frame 2;

[0026] Sealing plates 6 are provided on both sides of the load-bearing plate 3. The sealing plates 6 are provided on the pillars 4. A through hole 13 is provided on the sealing plate 6 on one side of the load-bearing plate 3. A lower pressing plate 14 is provided in the through hole 13. The top of the lower pressing plate 14 extends to the top of the sealing plate 6.

[0027] A sealing plate 6 with a through hole 13 on one side of the bearing plate 3 is set as an entry and exit area, and the top of the lower pressing plate 14 is set in an arc shape, so that when the wheel of the car presses over the lower pressing plate 14, the lower pressing plate 14 can be easily moved downward;

[0028] The two sides of the lower pressing plate 14 are fixedly connected with stoppers 21, and the bottom of the sealing plate 6 is provided with a plurality of limit grooves 5, and the stoppers 21 are arranged in the limit grooves 5;

[0029] By setting the stopper 21, when the tension spring 16 cooperates with the fixing ring 17 and the positioning column 15 to pull, so that the positioning column 15 pushes the lower pressing plate 14 to return to its original position, the stopper 21 can move into the limiting groove 5, so that the lower pressing plate 14 can be positioned;

[0030] The inner bottom of the mounting groove 7 is fixedly connected with a positioning seat 10, and the bottom of the mounting plate 8 is fixedly connected with a bottom plate 9, and the bottom plate 9 is fixedly installed in the positioning seat 10;

[0031] By setting the positioning seat 10, the bottom plate 9 can be easily installed with the positioning seat 10;

[0032] The inner bottom of the mounting groove 7 is fixedly connected with a plurality of positioning blocks 12, and the bottom of the mounting plate 8 is fixedly connected with a plurality of guide posts 11 corresponding to the positioning blocks 12, and the lower ends of the guide posts 11 are inserted into the positioning blocks 12;

[0033] By setting the positioning block 12, the positioning block 12 cooperates with the guide column 11 to position the mounting plate 8, thereby improving the stability of the mounting plate 8 after installation;

[0034] A plurality of groups of dampers 19 are fixedly mounted on the top of the mounting plate 8, and the upper ends of the piston rods of the dampers 19 are in contact with the bottom of the lower pressing plate 14;

[0035] A handle 20 is fixedly mounted on the top of the mounting plate 8, and the mounting plate 8 can be easily taken by the handle 20;

[0036] In specific use, when the front wheels of the car enter the entry and exit area, the front wheels of the car slowly roll over the lower pressing plate 14 and pass through the entry and exit area. The lower pressing plate 14 moves downward under the rolling of the car wheels, so that the lower pressing plate 14 can be pressed on the weighing sensor 18, thereby generating a set of signals, which will count the weight detected by the weighing sensor 18 and temporarily store it;

[0037] When the rear wheels of the car slowly roll over the lower pressing plate 14 and pass through the entry and exit area, the lower pressing plate 14 moves downward under the rolling of the car wheels, so that the lower pressing plate 14 can press on the weighing sensor 18, thereby generating a second set of signals, which will count the weight detected by the weighing sensor 18 and combine it with the first set of weights to obtain the total weight of the car;

[0038] Before the next action, the system will make a judgment. When the actual load of the car exceeds 95% of the rated load, the overload limiter should send out an alarm signal and notify the management personnel in the monitoring room. When the actual load of the parking equipment exceeds the rated load by 100% to 110%, the overload limiter will take effect and automatically cut off the lifting power supply.

[0039] After the automobile wheel passes the lower pressing plate 14, the tension spring 16 can pull the positioning column 15 through the fixing ring 17, so that the positioning column 15 pushes the lower pressing plate 14 when moving, so that the lower pressing plate 14 returns to its original position.
