In view of the foregoing, the purpose of this utility model just is to provide a kind of automobile axle load measuring apparatus, and it adopts and turns over fine strain of millet formula structural design, and practicality is more extended the deadline in the requirement of water proofing property, and maintenance and repair is convenient.

The purpose of this utility model is achieved in that a kind of automobile axle load measuring apparatus, this device comprises is located at below ground, the box beam that upper surface and ground maintain an equal level, this box beam is made up of upper and lower surface and middle support body, each affixed one turns over fine strain of millet on overhead along the both sides of this box beam, and it is into a single integrated structure with box beam and do not contact with the earth to turn over fine strain of millet on this; Respectively be provided with LOAD CELLS under the fine strain of millet turning on the both sides, this LOAD CELLS all with on turn over fine strain of millet and the earth and contact and be connected, and have signal wire to be connected with a weighing instrument.

According to technique scheme, described LOAD CELLS can be by support and the earth Joint.

According to technique scheme, described support body can be the channel-section steel, joist steel and the box plate that are crisscross arranged and forms.

According to technique scheme, and then can on both sides, turn over the cover body that adds a tool waterproof, attractive in appearance and warning function outside the fine strain of millet structure.

Because above technical scheme, the utility model will detect automobile mounted weight and be decomposed into the heavy metering of each axletree axle of automobile, turn over fine strain of millet formula structural design owing to having adopted again, and LOAD CELLS is located at more than the face of land, have better waterproof, reliability height, life-span are more lasting.Maintain easily simultaneously, needn't resemble traditional weighing device and need use large lifting equipment.Heavily transfinite when detecting when being used for the on-highway motor vehicle axle, automobile need only cross at the upper surface of the utility model box beam, can dynamically finish the detection of vehicle axle weight and vehicle load,, guarantee that better highway is intact and safe and smooth for guaranteeing the serious effective detection means of providing convenience of enforcing the law.

Below in conjunction with drawings and the specific embodiments the utility model is further described in more detail.

Fig. 1 is the synoptic diagram of existing weighing device.

Fig. 2 is an installation sectional view of the present utility model.

Fig. 3 is an installation schematic top plan view of the present utility model.

Fig. 4 is an installation dimension synoptic diagram of the present utility model.

At first, see also shown in Figure 2, the utility model mainly is located at below ground by one, the box beam 1 that upper surface and ground maintain an equal level is formed, this box beam is made up of upper surface 11, lower surface 12 and middle support body 13, each affixed one turns over fine strain of millet 2 on overhead along the both sides of this box beam 1, and it is into a single integrated structure and do not contact with the earth 10 to turn over fine strain of millet 2 and box beam 1 on this.On both sides, turn over fine strain of millet and respectively be provided with LOAD CELLS 32 times, these LOAD CELLS 3 all with on turn over fine strain of millet 1 and the earth 10 and contact and be connected, and have signal wire 4 to be connected with a weighing instrument 5.Also LOAD CELLS 3 can be installed on the support 6, support 6 is fixedly connected with the earth 10.By shown in Figure 3, in the present embodiment, LOAD CELLS 3 is turned on the both sides in the fine strain of millet structure for being symmetrically distributed in, and respectively establishes two.

Again referring to shown in Figure 4, when concrete the installation, can on both sides, turn over the cover body 7 that adds the attractive in appearance and warning function of a tool outside the fine strain of millet structure, have certain waterproof effect simultaneously.Since on turn over the fine strain of millet structure and be located at the above approximately 200mm in ground, ponding generally speaking all can not cause damage to LOAD CELLS.Owing to adopted and turned over fine strain of millet formula structural design, when LOAD CELLS 3 breaks down, need only take away cover body 7, can unload LOAD CELLS 3 detects and keeps in repair, be located at because of sensor and need below the scale body scale body to be sling and needn't resemble traditional weighing-appliance, can carry out relevant detection and maintenance by large lifting equipment.
