Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of level adjustment devices, in particular to a level adjustment device for electronic vehicle scales. Background Art
[0002] Electronic truck scales are mainly composed of load carriers, weighing display instruments (hereinafter referred to as instruments), weighing sensors (hereinafter referred to as sensors), connectors, limit devices, junction boxes and other components. They can also be equipped with printers, large display screens, computers, weighing management software, and voltage-stabilized power supplies and other external devices. The scale is connected to a computer to print a weighing slip, which is a new management method at present. The weighing management system is composed of computers, printers, instruments, and scale software. The vehicle is weighed twice, and the gross weight minus the tare weight is used to print the net weight. Its working principle is as follows: the object to be weighed or the truck is placed on the load carrier table. Under the action of gravity, the gravity is transmitted to the weighing sensor through the load carrier, causing the elastic body of the weighing sensor to deform, and the strain gauge bridge attached to the elastic body loses balance, outputting an electrical signal proportional to the weight value, amplifying the signal through a linear amplifier, and then converting it into a digital signal through A / D. The weight signal is processed by the microprocessor (CPU) of the instrument and the weight data is directly displayed. After configuring the printer, the weighing data can be printed and recorded. If a computer and weighing management software are configured, the measurement data can be comprehensively managed through the weighing management system.
[0003] Most traditional electronic truck scales do not have the leveling function of a symmetrical panel, which results in the inability to correct the scale after it is offset. When objects are weighed frequently, the uneven force on the electronic truck scale causes increased grinding, which greatly reduces the service life of the electronic truck scale. Utility Model Content

The utility model can realize fast and efficient leveling of a symmetrical body through a plurality of lifting rods, thereby solving the problem that most of the traditional electronic truck scales do not have the leveling function of the panel of the symmetrical body, resulting in the inability to correct the offset of the scale. When objects are weighed frequently, the uneven force on the electronic truck scale causes aggravated grinding, which greatly reduces the service life of the electronic truck scale.
[0005] In order to solve the above technical problems, the utility model provides a horizontal adjustment device for an electronic truck scale, comprising a plurality of adjustment mechanisms for leveling the weighing pan of the weighing body, which are located below the weighing body of the electronic truck scale and are arranged on a support frame on a horizontal ground.

The utility model can realize fast and efficient leveling of a symmetrical body through a plurality of lifting rods, and solves the problem that most of the weighing bodies of traditional electronic truck scales do not have the leveling function of the panel of the symmetrical body, resulting in the inability to correct the offset of the weighing body. When objects are weighed frequently, the uneven force on the electronic truck scale causes the grinding to be aggravated, which greatly reduces the service life of the electronic truck scale.
[0006] A plurality of elastic parts are hingedly provided between the support frame and the scale body, and elastic auxiliary support operations between the support frame and the scale body can be realized through the plurality of elastic parts, so as to avoid excessive impact force directly squeezing the lifting component during the downward movement of the scale body after bearing the load, thereby preventing the lifting component from being damaged due to excessive impact force, thereby greatly improving the service life of the lifting component and the sensor electronic components in the scale body.
[0007] Electronic levels are provided on the outer walls of the front and rear sides of the scale body, respectively. Whether the scale body is leveled can be detected by the electronic level, which is more intuitive and convenient.
[0008] The lifting rod is an electric push rod or a hydraulic push rod, and the top block is a hemispherical structure. The purpose of this is to greatly reduce the low correction efficiency or failure caused by the uneven upper surface of the top block after wear due to the plane structure. The surface contact can be changed into point contact or line contact, which greatly improves the leveling accuracy. The controller is a PLC controller, and the brand is Siemens. The lifting rod and the electronic level are electrically connected to the controller. There are 15 adjustment mechanisms, 5 in a group, divided into 3 groups, and the 3 groups are evenly distributed on the front side, middle side and rear side of the upper part of the support frame. Through the electrical connection between the controller and the electronic level and each lifting rod, the information on whether the leveling is on the electronic level can be transmitted to the controller, and the controller analyzes and processes it, and controls the output rod of the corresponding lifting rod to extend or retract to lift the lifting cylinder and the top block upward or downward symmetrically, thereby realizing fast and efficient leveling operation, and can realize the adjustment of the extension and retraction length of the output rods of a certain or multiple lifting rods at the same time, so that the operation is more convenient.
