Detailed Description

As shown in fig. 1 and 2, a vehicle chassis height detecting device of the present embodiment includes a platform entrance frame 2 and a chassis height detecting mechanism 1 disposed on the platform entrance frame 2; the chassis height detection mechanism 1 comprises a lever assembly and a detection switch assembly;

the lever assembly comprises a lever arm 12 which is rotatably arranged on the platform entrance frame 2, a roller 11 which is arranged at one end of the lever arm 12 and is used for contacting with a vehicle chassis, and a balancing weight 14 which is arranged at the other end of the lever arm 12; in the embodiment, two lever arms 12 are arranged in parallel, the two lever arms 12 are hinged with the platform inlet frame 2 through hinged supports 13, and a roller shaft and two counterweight connecting shafts 15 are fixedly connected between the two lever arms 12; the roller 11 is sleeved on the roller shaft and can rotate around the roller shaft, and the length and the number of the rollers 11 are determined according to the minimum width of the chassis of the vehicle to be screened; in the embodiment, the number of the rollers 11 is three, and the rollers 11 are made of plastics or other materials with lower hardness, so that the chassis is prevented from being damaged in the process of contacting with the chassis of the vehicle;

in this embodiment, there are two counterweight blocks 14, each counterweight block 14 has two through holes, so that two counterweight connecting shafts 15 pass through the counterweight block 14 through the through holes, and the counterweight block 14 is limited between the shaft shoulder of the counterweight connecting shaft 15 and the lever arm 12; in this embodiment, the force arm of the lever arm 12 at the side where the roller 11 is installed is shorter, and the force arm at the side where the counterweight 14 is installed is longer, so that when the lever assembly is not affected by external force, one end of the lever arm 12 at the side where the roller 11 is installed will be tilted upwards, and one end of the counterweight 14 at the side where the counterweight 14 is installed will sink; the weight of the balancing weight 14 is selected to ensure that the balancing weight end of the lever arm 12 always tilts upwards when the vehicle does not pass through, so as to avoid misoperation, and meanwhile, the weight of the balancing weight 14 also ensures that the triggering acting force of the roller 11 on the chassis is proper when the vehicle passes through, so that the chassis of the vehicle cannot be damaged;

in this embodiment, the detection switch assembly includes a rotary switch 18 fixed to the platform entrance frame 2 and a detection swing arm 17 fixed to a detection shaft of the rotary switch 18; the rotary switch 18 can adopt the existing rotary detection proximity switch, and is fixed on the platform entrance frame 2 through a switch bracket; the detection shaft of the rotary switch 18 is fixedly connected with the detection swing arm 17 through a connecting rotating body 19; the connecting swivel body 19 is fixed on a detection shaft of the rotary switch 18, the connecting swivel body 19 is provided with a mounting groove and a cover plate which are matched with the detection swing arm 17, the detection swing arm 17 can slide in the mounting groove, so that the extending length of the detection swing arm 17 is adjusted, and after the adjustment is finished, the cover plate is covered and fastened by a fastener to fix the swing arm and the connecting swivel body 19; the outer end of the detection swing arm 17 is provided with a roller and is in contact fit with the lever arm 12 through the roller 16.
