DETAILED DESCRIPTION
[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0025] A typical implementation of the present utility model is as follows Figure 1 As shown, a vehicle overweight detection mechanism for parking equipment includes a lifting frame 1 and a vehicle loading plate 2. The vehicle loading plate 2 is arranged at the bottom of the lifting frame 1, and a lifting device 3 is arranged on the top of the lifting frame 1. The lifting device 3 is fixedly connected to the vehicle loading plate 2, and the vehicle loading plate 2 is driven to rise and fall through the lifting device 3.
[0026] It can be known that there are two sets of lifting devices 3, and the two sets of lifting devices 3 have the same structure and are symmetrically arranged on both sides of the top of the lifting frame 1, so as to lift both sides of the vehicle loading plate 2 at the same time to ensure the stability of the vehicle loading plate 2 when lifting. In this embodiment, only one set of lifting devices 3 is described.
[0027] like Figure 2 As shown, the lifting device 3 includes a lifting motor 301, which is fixed at one end of the top of the lifting frame 1. A first sprocket 302 is fixedly connected to the output shaft of the lifting motor 301. A second sprocket 303 is arranged below the first sprocket 302. The first sprocket 302 and the second sprocket 303 are connected by a first chain transmission, so that the lifting motor 301 drives the second sprocket 303 to rotate. A third sprocket 304 is also arranged on the top of the lifting frame 1. The third sprocket 304 is located at one end of the top of the lifting frame 1 away from the second sprocket 303. The second sprocket 303 and the third sprocket 304 are connected by a second chain 305.
[0028] A fourth sprocket 306 and a fifth sprocket 307 are also provided on the top of the lifting frame 1. The fourth sprocket 306 is located on one side of the second sprocket 303, and the fifth sprocket 307 is located on one side of the third sprocket 304. A third chain 308 is wound around the fourth sprocket 306. One end of the third chain 308 is fixedly connected to the second chain 305 through a first chain connector 309. The other end of the third chain 308 bypasses the fourth sprocket 306 and is fixed to the rear end of the vehicle loading plate 2. A fourth chain 310 is wound around the fifth sprocket 307. One end of the fourth chain 310 is fixedly connected to the second chain 305 through a second chain connector 311, and the other end bypasses the fifth sprocket 307 and is fixed to the front end of the vehicle loading plate 2.
[0029] When the vehicle loading plate 2 is lifted, the lifting motor 301 drives the second chain 305 to rotate through the second sprocket 303. The second chain 305 is respectively connected to the third chain 308 and the fourth chain 310 through the first chain connector 309 and the second chain connector 311. The third chain 308 and the fourth chain 310 are respectively fixedly connected to the two ends of the vehicle loading plate 2, so that the lifting motor 301 is used to lift the vehicle loading plate 2.
[0030] The third chain 308 is provided with a first stretching device 312 , which is located between the first chain connector 309 and the fourth sprocket 306 . The fourth chain 310 is provided with a second stretching device 313 , which is located between the second chain connector 311 and the fifth sprocket 307 .
[0031] The first stretching device 312 and the second stretching device 313 have the same structure, and only the structure of the first stretching device 312 is described here. Figure 3 As shown, the first stretching device 312 includes a sleeve 3121 and a telescopic rod 3122. The sleeve 3121 and the telescopic rod 3122 are both made of metal. One end of the sleeve 3121 is closed and the other end is open. The open end of the sleeve 3121 is provided with a through hole 3123 with the same diameter as the telescopic rod 3122. A cavity 3124 is provided inside the sleeve 3121. The cavity 3124 is cylindrical, and the inner diameter of the cavity 3124 is larger than the inner diameter of the through hole 3123. One end of the telescopic rod 3122 passes through the through hole 3123 and extends to the cavity 312 4, one end of the telescopic rod 3122 located in the cavity 3124 is fixedly connected to a slider 3125, and the slider 3125 is disc-shaped, and its diameter is the same as the diameter of the cavity 3124, so that the telescopic rod 3122 can slide along the axial direction of the sleeve 3121. A spring 3126 is sleeved on the outer side of the telescopic rod 3122, and one end of the spring 3126 is connected to the top surface of the cavity 3124, and the other end is connected to the top surface of the slider 3125. The spring 3126 can limit the movement of the telescopic rod 3122 along the axial direction of the sleeve 3121.
[0032] When the vehicle moves onto the vehicle loading plate 2 , under the action of the weight of the vehicle body, the springs in the first stretching device 312 and the second stretching device 313 are squeezed, so that both the first stretching device 312 and the second stretching device 313 are elastically deformed.
[0033] A first overweight detection device 4 is arranged below the first stretching device 312 , and a second overweight detection device 5 is arranged above the second stretching device 313 . The first overweight detection device 4 is used to detect the deformation of the first stretching device 312 , and the second overweight detection device 5 is used to detect the deformation of the second stretching device 313 .
[0034] An alarm device 6 is also provided at the front end of the lifting frame 1, and the first overweight detection device 4, the second overweight detection device 5 and the alarm device 6 are all electrically connected to the equipment controller.
[0035] The first overweight detection device 4 has the same structure as the second overweight detection device 5. The overweight detection device is used to detect the deformation of the stretching device, so as to determine whether the vehicle on the vehicle loading plate 2 is overweight. Figure 4 As shown, the first overweight detection device 4 includes a first induction switch 401 and a second induction switch 402, and the first induction switch 401 and the second induction switch 402 are arranged side by side. The first induction switch 401 and the second induction switch 402 are arranged corresponding to the first stretching device 312. In a normal state, the first induction switch 401 can detect the first stretching device 312, but since the elastic deformation of the first stretching device 312 is small in a normal state, the second induction switch 402 cannot sense the first stretching device 312, which means that the vehicle weight is normal at this time and the equipment can operate normally. When the vehicle weight exceeds the specified weight, since the elastic deformation of the first stretching device 312 is too large, the second induction switch 402 senses the first stretching device 312, which means that the vehicle is overweight, and the equipment controller controls the equipment to stop running and sends an alarm through the alarm device 6.
[0036] In this embodiment, a stretching device and an overweight detection device are provided on the chains connecting the four corners of the vehicle loading plate 2, so as to detect the weight of the four corners of the vehicle and ensure the accuracy of the weight detection.
[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
