Detailed Description
In the figures 1 and 2, the first and second parts, in fig. 3, a mounting hole is drilled at a proper position of a rear support panel 2 of a mixer truck, a bottom plate is fixedly connected with the rear support panel 2 of the mixer truck through four elastic legs arranged at four corners of the lower end part of the bottom plate, the four elastic legs 1 can be directly welded at the mounting hole, attention is paid to tangency of a track 6 of the mixer truck and a roller 5 during welding and fixing, the fixed rear bottom plate is parallel to the rear support panel 2, two symmetrical mounting frames 3 are erected at the upper end part of the bottom plate, round holes are arranged at the upper end parts of the two mounting frames 3, a bearing 4 is respectively arranged in the two round holes, a roller is arranged in the two bearings 4, the roller 5 is fixedly provided with an outer surface which is tangent to the track 6 of the mixer truck and can rotate along with the track 6 of the mixer truck, an induction disc chuck 7 is outwards extended and fixed at one end of the roller, the induction disc 7 can coaxially; a proximity switch mounting bracket is also vertically arranged on the bottom plate on one side of the induction faceplate 7, a proximity switch 8 is fixed on the proximity switch mounting bracket, and the induction plane of the proximity switch 8 corresponds to the faceplate gear on the periphery of the induction faceplate 7;
the automobile steering wheel further comprises a controller which can receive signals of the proximity switch 8 and transmit rotating speed to a display screen in the cab through calculation, and the controller is electrically connected with the proximity switch 8 and the display screen.
The mounting frame 3 comprises a lower mounting frame and an upper mounting frame arranged at the upper end of the lower mounting frame, threaded through holes are formed in the corresponding positions of the two ends of the lower mounting frame and the upper mounting frame, and two bolts sequentially penetrate through the bottoms of the corresponding threaded through holes in the upper mounting frame and the lower mounting frame and are fixed through nuts; semicircular grooves are formed in the opposite positions of the upper mounting frame and the lower mounting frame, and circular holes matched with the bearings 4 are formed after the two semicircular grooves are connected; the induction disc chuck 7 is fixed on the roller through a fastening nut arranged at the shaft end of the roller.
The general working environment of the concrete mixing transport vehicle is on a construction site, the road surface is mostly uneven, and the tank body is always jumped. The elastic support legs 1 are adopted, so that the speed measuring device can jump along with the stirring drum track 6, and the roller 5 of the measuring device is ensured to be tangent to the stirring drum track 6 all the time; and the elastic supporting legs 1 ensure that the measuring device is not broken by the rail when the roller path of the mixing drum jumps down. The two ends of the rolling shaft are supported by bearings 4 and fixedly connected with the mounting frame 3, so that the rolling of the roller 5 is flexible. The response faceplate 7 can be along with the roller bearing and the gyro wheel 5 coaxial rotation together, guarantees coaxial rotation, and the size of response faceplate determines the sensitivity of response, and the bigger is better in principle, and the number of teeth is more accurate more, and actual mounted position is limited, and therefore general size is suitable just. The induction distance of the proximity switch is generally 4-8 mm, and the induction effective area is generally 2/3 of the induction plane of the proximity switch, so the size of the induction faceplate gear is generally the same as that of the induction plane of the proximity switch.
