Description

Technical Field

[0001] The utility model relates to the technical field of measuring equipment, in particular to a forklift scale. Background Art

[0002] Forklifts are used to move heavy objects and are widely used in various scenarios such as factories, logistics, and warehouses to transport materials. Their functionality and efficiency directly impact the operational efficiency and cost control of production lines. With the development of intelligent and automated technologies, the requirements for the functionality and accuracy of forklifts are increasing. In particular, when it comes to measuring the weight of goods, forklifts need to be equipped with weighing systems to achieve weighing and recording functions. Existing forklift scales use traditional weighing modules, resulting in complex internal structures, increased raw materials required for production, and thus increased costs. This leads to inaccurate weighing, which to a certain extent limits their application in inventory management, logistics scheduling, and other areas. Utility Model Content

[0003] The purpose of the utility model is to provide a forklift scale, aiming to solve the above problems.

[0004] To achieve the above objectives, the present invention provides the following technical solutions:

[0005] A forklift scale comprises: a body frame, a supporting cover plate, a triangular plate, a rocker arm assembly, and a drive device. The body frame comprises two fork legs and a crossbeam. The two fork legs are arranged opposite to each other on the left and right, and the rear ends are connected by the crossbeam. The surfaces of the two fork legs are provided with sliding grooves, and push rods are provided in the sliding grooves. The front ends of the push rods are provided with auxiliary rollers. The triangular plate is provided on the crossbeam. One end of the rocker arm assembly is connected to the triangular plate, and the other end is connected to the drive device. At least four fixings are provided on the fork legs, and flat-plate weighing sensor assemblies are fixedly installed on the fixings. The supporting cover plate is fixedly installed on the flat-plate weighing sensor assembly through a connecting shaft, and is used to carry goods and weigh them.

[0006] Furthermore, the push rod is a single-rib push rod.

[0007] Furthermore, at least four connecting shafts are fixedly provided in the supporting cover plate, corresponding to the flat-plate weighing sensor components.

[0008] Furthermore, the connecting shaft is divided into connecting shaft A and connecting shaft B, which are integrally formed. The diameter of connecting shaft A is smaller than that of connecting shaft B to adapt to different connection and support requirements.

[0009] Furthermore, the connecting shaft is arranged corresponding to the position of the flat-plate weighing sensor assembly, the connecting shaft A vertically passes through the flat-plate weighing sensor assembly, and the connecting shaft B is fixed on the flat-plate weighing sensor assembly.

[0010] Furthermore, the A connecting shaft vertically passes through the flat-plate weighing sensor assembly to limit the position of the supporting cover plate; the B connecting shaft is fixed above the flat-plate weighing sensor assembly to transfer the weight of the supporting cover plate and the cargo to the weighing sensor.

[0011] Furthermore, the number of the flat-plate weighing sensor assemblies is at least four, which are fixedly installed at appropriate positions on the upper part of the fork leg to ensure the accuracy and stability of weighing. At this time, the push rod is located at the lower part of the flat-plate weighing sensor assembly.

[0012] Furthermore, the push rod can also be a two-rib push rod. In this case, the connecting shaft vertically passes through the middle gap between the two rib push rods and is connected to the flat-plate weighing sensor assembly to provide another stable support and connection solution.

[0013] 1. Furthermore, the flat plate weighing sensor assembly (11) can be installed in the sliding groove on the left and right sides respectively, at the bottom of the fork leg, and the push rod is located at the upper part of the flat plate weighing sensor assembly.

[0014] The beneficial effects are as follows: the forklift scale of the utility model has a tighter structure, is compact and simple, light in weight, has high weighing accuracy, reduces the use of raw materials, and reduces production costs. BRIEF DESCRIPTION OF THE DRAWINGS
