Description

Technical Field

[0001] This utility model belongs to the field of parking equipment, specifically relating to a fixed intelligent precision dynamic weighing system for parking equipment. Background Technology

[0002] Mechanical parking systems can park cars vertically, saving land and maximizing space utilization. The existing weighing systems used in mechanical parking equipment have the following problems: In some mechanical parking equipment, the weighing system is installed at the lifting point of the elevator chain (or the chain or wire rope lifting point on the machine room floor). Because the lifting point has a large load and is susceptible to impact, and there is friction between the elevator guide rail and the elevator, not only are the weighing sensors expensive, but there are also safety issues and large errors. Pit-type simple lifting parking equipment requires a weighing device to be designed for each parking space, which is too costly. In some vertical circulation parking equipment, the weighing system is designed at the top guide rail position of the vertical circulation parking equipment. It needs to weigh the weight of all cars, car platform and guide rail. The load is too large, the load-bearing capacity of the weighing sensors is large, the cost is high, and it is unsafe. In addition, the running resistance of the vertical circulation guide rail and frame components is large, which also leads to large errors. Alternatively, the weighing system of mechanical parking equipment needs to weigh the entire weight of the car. The weighing platform needs to accommodate the entire car. The weighing platform occupies a large space, and it is difficult to install a weighing platform that can accommodate the entire car. In some types of garages, there is not enough space to install it. On the other hand, when the weight of a vehicle exceeds the rated value, most weighing systems can only emit an alarm beep and do not have the function of voice broadcasting the weight. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a fixed intelligent precision dynamic weighing system for parking equipment, which can effectively reduce the space occupied, reduce the load on the weighing sensor during the weighing process, and effectively improve the safety and stability of the weighing process.

[0004] The specific technical solution adopted in this utility model is as follows:

[0005] A fixed intelligent precision dynamic weighing system for parking equipment is characterized by being installed on the ground between the garage entrance / exit and the vehicle carrier platform. The weighing system includes a platform plate, a bottom mounting plate, and a weighing sensor. The platform plate is located above the bottom mounting plate, and the weighing sensor is positioned between the platform plate and the bottom mounting plate. The platform plate is connected to the ground via the bottom mounting plate. Two sets of front wheels or two sets of rear wheels of a vehicle simultaneously pass over the platform plate, with the front and rear wheels of the vehicle contacting the platform plate sequentially. The platform plate and the vehicle carrier platform are coplanar.

[0006] The lower end of the platform plate is provided with a platform frame welded together, and the platform plate is connected to the weighing sensor by means of the platform frame welded together.

[0007] A weighing sensor mounting plate is provided below the welded platform frame.

[0008] Weighing sensors are installed at the four corners of the platform plate.

[0009] The garage is equipped with a first-round detection sensor and a second-round detection sensor, which are respectively located at the front and rear ends of the platform plate.

[0010] The garage is also equipped with a voice box, which is connected to the garage frame via a voice bracket.

[0011] The long side of the platform plate is perpendicular to the direction in which the car enters the garage.

[0012] The upper surface of the platform plate is provided with anti-slip patterns.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model adopts a platform plate set on the garage floor to improve the load-bearing capacity of the platform plate; the platform plate allows the front wheels or rear wheels of the car to pass over the platform plate at the same time, and the front wheels and rear wheels contact the platform plate in sequence, that is, the front wheels and rear wheels do not press over the platform plate at the same time. The weighing system weighs the front wheels and rear wheels separately, and calculates the weight of the entire car without weighing the entire car. While reducing the area of ​​the platform plate, it can also reduce the load on the weighing system during the weighing process, and improve the safety and stability of the weighing system.

[0015] 2. Weighing sensors are installed at the four corners of the platform plate, which can comprehensively and evenly measure the weight distribution of the car wheels, thereby improving the accuracy of weighing;

[0016] 3. By setting the first and second rounds of detection sensors, it is possible to determine whether the car is entering or leaving the garage, and the car is weighed only when it enters the garage;

[0017] 4. A voice box has been added. After weighing, the voice box will announce the car's weight, so that drivers and parking management personnel can know the weight of the car. If the car's weight exceeds the limit, the voice box can play an alarm to remind drivers and parking management personnel to pay attention. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] Specific implementation examples Figure 1-8 As shown, this utility model relates to a fixed intelligent precision dynamic weighing system for parking equipment. The key feature is that it is installed on the ground between the garage entrance / exit and the vehicle carrier platform 1. The weighing system includes a platform plate 2, a bottom mounting plate 3, and a weighing sensor 4. The platform plate 2 is located above the bottom mounting plate 3, and the weighing sensor 4 is positioned between the platform plate 2 and the bottom mounting plate 3. The platform plate 2 is connected to the ground via the bottom mounting plate 3. Two sets of front wheels or two sets of rear wheels of a car simultaneously pass over the platform plate 2, with the front and rear wheels of the car sequentially contacting the platform plate 2. The platform plate 2 and the vehicle carrier platform 1 are coplanar. A power distribution cabinet 15 is installed inside the garage, and an automatic door 16 is located at the garage entrance / exit.

[0030] Platform 2 is installed on the garage floor, and the bottom mounting plate 3 is connected to the garage floor by chemical bolts. Platform 2 has a strong load-bearing capacity. The front wheels and rear wheels of the car contact platform 2 in sequence, that is, the front wheels and rear wheels do not contact platform 2 at the same time. This allows the front wheels and rear wheels of the car to pass over platform 2 in sequence. The weighing system first weighs the weight of the front wheels and then weighs the weight of the rear wheels. The system calculates the sum of the weights of the front and rear wheels to obtain the weight of the entire car. There is no need to weigh the entire car, which reduces the area of ​​platform 2. The platform 2 occupies less space and also reduces the load on the weighing system during the weighing process, improving the safety and stability of the weighing system.

[0031] Preferably, the long side of the platform plate 2 is set perpendicular to the direction in which the car enters the garage, ensuring that the two front wheels or two rear wheels of the car can simultaneously run over the platform plate 2. The short side of the platform plate 2 is set parallel to the direction in which the car enters the garage. The platform plate 2 has a small width and occupies a small area, which meets the requirements for weighing the front and rear wheels of the car separately.

[0032] The ground in front of the weighing system entrance and exit is a plane. The upper surface of the platform plate 2 is the same plane as the ground in front of the weighing system entrance and exit. That is, when the front wheels of the car are in contact with the passing surface of the platform plate 2, the front wheels and rear wheels of the car are on the same horizontal plane. The weighing process at this time is as follows: the system measures the weight of the front wheels and the weight of the rear wheels. The system automatically filters out the smaller values ​​or the values ​​with large fluctuations, and sums the two weighing results to obtain the total weight of the car.

[0033] The ground in front of the weighing system entrance and exit is a slope, and the passage surface of platform plate 2 is higher than the ground in front of the weighing system entrance and exit. When the front wheels enter the parking space, they first pass through the slope, then through platform plate 2, and then drive onto the vehicle carrier plate 1. When the front wheels reach platform plate 2, the rear wheels are still on the ground below platform plate 2, and there is a height difference between the front and rear wheels. At this time, the weight of the front wheels will be lighter than when there is no slope. By actually measuring the slope angle on site, the coefficient of the front wheel weight is calculated (or by comparing the ratio coefficient of the theoretical weight of the front wheel to the actual weight), and then the coefficient is entered into the weighing system. The system calculates the weight of the front wheels of the car. When the rear wheels pass through platform plate 2, since the front wheels are already on the vehicle carrier plate 1, the front wheels and the rear wheels are at the same height. Therefore, the weighing system detects the weight of the rear wheels of the car as the actual weight. The weighing system then sums the detected weights of the front wheels and the rear wheels to obtain the actual weight of the car.

[0034] In this embodiment, the ground in front of the weighing system entrance and exit is a plane.

[0035] The lower end of the platform plate 2 is provided with a platform frame welded joint 5, and the platform plate 2 is connected to the weighing sensor 4 through the platform frame welded joint 5. The platform frame welded joint 5 provides support for the platform plate 2, enhances the strength and load-bearing capacity of the platform plate 2, and prevents the platform plate 2 from being damaged by pressure.

[0036] Platform plate 2 is connected to platform frame 5 by bolts, which facilitates the installation, commissioning and subsequent maintenance of platform plate 2.

[0037] like Figure 6 As shown, the platform frame weld 5 is made of multiple rectangular tubes welded together.

[0038] A weighing sensor mounting plate 6 is provided below the platform frame welding 5. The weighing sensor 4 is connected to the weighing sensor mounting plate 6 and the bottom mounting plate 3 by bolts. The weighing sensor 4 is connected to the platform frame welding 5 by means of the weighing sensor mounting plate 6.

[0039] Weighing sensors 4 are respectively installed at the four corners of the platform plate 2, that is, weighing sensor mounting plates 6 are installed at the four corners of the platform frame welded 5. The weighing sensors 4 provide good support for the platform plate 2 and the platform frame welded 5, and enhance the stability of the platform plate 2. When a car passes over the platform plate 2, the weight of the car wheels will be transmitted to each corner point through the platform plate 2. The weighing sensors 4 installed at the four corners can comprehensively and evenly measure the weight distribution of the car wheels, thereby improving the accuracy of weighing.

[0040] The garage is equipped with a first-round detection sensor 7 and a second-round detection sensor 8, which are respectively located at the front and rear ends of the platform plate 2. In this embodiment, the vehicle-carrying plate 1 and the platform plate 2 are arranged adjacent to each other. The garage is also equipped with a vehicle presence sensor 9, which is correspondingly set to the vehicle-carrying plate 1 to detect whether a vehicle has arrived on the vehicle-carrying plate 1. During the process of a vehicle entering the garage, when the front wheels of the vehicle first contact the platform plate 2, the first-round detection sensor 7 detects the front wheels of the vehicle and begins to record the weight of the vehicle on the front wheels of the platform plate 2 until the second-round detection sensor 8 detects that the front wheels have left the platform plate 2, at which point the weighing of the front wheels ends. Subsequently, the rear wheels of the vehicle pass through the platform plate 2, and the detection steps for the rear wheels are the same as those for the front wheels. Figure 4 As shown, when the car has been detected by sensor 9 and parked on the vehicle platform 1, and the second round of detection sensor 8 determines that the rear wheel weighing is finished, the weighing system calculates the total weight of the car.

[0041] The first-round detection sensor 7, the second-round detection sensor 8, and the vehicle presence / absence sensor 9 are all photoelectric sensors. The configuration of the first-round detection sensor 7, the second-round detection sensor 8, and the vehicle presence / absence sensor 9 can determine whether the vehicle is entering or leaving the garage.

[0042] like Figure 5 , Figure 7As shown, the garage is also equipped with a voice box 10, which is connected to the garage frame via a voice bracket 11. Specifically, the voice box 10 is mounted on the voice bracket 11, and the voice bracket 11 is fixed to the rear frame crossbeam of the garage with bolts. After the garage system calculates the weight of the car, it transmits the car weight signal to the voice box 10, which announces the car weight, allowing users or managers to clearly know the weight of the car entering the garage. If the weight in the garage exceeds the rated weight, the system will issue an alarm signal.

[0043] like Figure 5 , Figure 8 As shown, an instrument box 13 is also installed in the garage. The instrument box 13 is mounted on an instrument bracket 14, which is fixed to the guardrail with bolts for easy operation by maintenance personnel.

[0044] Furthermore, the upper surface of the platform plate 2 is provided with anti-slip patterns, and the platform plate 2 is treated with orange powder coating. This not only effectively prevents the car from slipping during the weighing process, but the eye-catching color also enhances the safety warning effect, reminding the driver to maintain a constant speed and straighten the front of the car when passing the platform plate 2 for weighing.

[0045] When platform slab 2 is on the same plane as the entrance / exit ground of the garage, a foundation pit is provided below platform slab 2. For example... Figure 9 As shown, a drainage hole 12 is provided in the foundation pit. The drainage hole 12 is connected to the drainage system outside the garage, which can effectively drain the water in the foundation pit, thereby avoiding the phenomenon of the weighing sensor 4 being soaked in water or the platform frame weld 5 being corroded due to rainwater, etc. The weighing sensor 4 is preferably a sensor with IP67 waterproof function.

[0046] Compared to weighing platforms installed at the lifting chain or wire rope suspension points, this weighing system is installed on the ground between the garage entrance / exit and the vehicle platform. It offers higher weighing accuracy, is unaffected by factors such as the lifting guide rails and operational impacts, has low susceptibility to external influences, and only bears approximately 0.6 times the weight of a car, making weighing safer, more stable, and highly accurate. This weighing system occupies little space, provides precise weighing, and only needs to be installed at the garage entrance / exit. It is suitable for vertical circulation, planar movement, vertical lifting, and lifting-and-sliding parking equipment.
