[0002] In the weighing field of modern industry and commerce, the truck scale as a large scale widely used in the weighing of various types of truck, the stability and reliability of its connecting structure are very important. The traditional truck scale is generally connected by several weighing bodies, and the connecting structure is mostly connected by bolts. Although the bolt can meet the fastening requirement to a certain extent, it has many disadvantages that are difficult to overcome.

[0003] During long-term use, the bolt is easily affected by the vibration and impact of the frequent entry and exit of the vehicle, resulting in loosening and falling off, and thus the overall structural stability of the truck scale is reduced, the measurement accuracy is damaged, and frequent fastening and maintenance not only consumes a lot of manpower and material resources, but also may affect normal production and operation due to untimely repair. Moreover, the installation process of the bolt connection is complicated, the threaded hole needs to be accurately aligned, the skill and operation environment of the installer are required to be high, and in some outdoor or complex working conditions, the installation efficiency and quality are difficult to guarantee.

[0004] In addition, the threaded connection of the bolt is easy to rust and corrode in harsh environments such as humidity, corrosion and dust, which makes it difficult to disassemble during maintenance. CONTENT OF THE UTILITY MODEL

[0005] The utility model solves the technical problem of providing a boltless pin column lapping truck scale, which facilitates the installation and connection of the scale body. To this end, the utility model adopts the following technical solutions:

[0006] A boltless pin column lapping truck scale includes a plurality of first weighing bodies and one or more second weighing bodies. The first weighing bodies are arranged at the head and tail ends of the truck scale, and the first and second weighing bodies are arranged at intervals. The two ends of the second weighing body are supported on the first weighing bodies at the two ends, and the first weighing body is provided with a sensor. The feature is that the facing parts of the first and second weighing bodies are provided with a horizontal pin column, and the two ends of the second weighing body are provided with a second weighing body connecting block. The second weighing body connecting block is provided with a U-shaped groove, which is lapped on the pin column.

[0007] On the basis of the above technical solutions, the utility model can also use the following further technical solutions, or use these further technical solutions in combination:

[0008] The first weighing body is provided with a first weighing body connecting block, the first weighing body connecting block is provided with a positioning hole, and the pin column is inserted into the positioning hole and welded with the first weighing body connecting block.

[0009] The first weighing body is in a box type structure, wherein a sensor mounting area is arranged, and the pin column is arranged in position alignment with the sensor in the left-right direction, so that the wheel can press over the pin column and the sensor when passing through the truck scale, and the stress state of the truck scale is improved.

[0010] The bottom diameter of the U-shaped groove is 1.0-2.0 times of the diameter of the pin column.

[0011] When the second weighing body connecting block is overlapped on the pin column, a gap of 5-20 mm is formed between the first weighing body and the second weighing body, and the scale body can freely move due to the bending moment.

[0012] The top of the first weighing body and the second weighing body is provided with an adjusting gap with a width of 5-15 mm, and the assembling problem caused by the machining error can be avoided.

[0013] The connecting structure between the first weighing body and the second weighing body does not adopt a bolt, but is connected by overlapping the U-shaped groove on the pin column, so that the horizontal movement of the scale body can be limited, and the truck scale can freely deform due to the change of the load.

[0014] The material of the pin column is high-strength alloy steel.

[0015] By adopting the technical scheme of the utility model, the problem caused by the bolt connection of the scale body can be avoided, the force transmission can be realized by adopting the connecting pin column, the pin column can play the horizontal limiting role and can keep the free change of the truck scale due to the load, and the pin column and the connecting block can be processed by using the standard material, so that the manufacturing is simple and the assembly is easy.
