Embodiment 1

[0044] Such as figure 1 As shown, the load-measuring device 100 provided by Embodiment 1 of the present invention includes a load-bearing force-transmitting assembly 10, a load cell, and a display for measuring the weight of large equipment such as a crane, and the load-bearing sensor is arranged behind the load-bearing force-transmitting assembly 10 , the load cell is electrically connected to the display with a wire. When in use, park large equipment such as a crane on the top of the load-bearing force transmission assembly 10, or slowly drive a crane and other large equipment over the load-bearing force transmission assembly 10, and the load cell measures the load. The deformation of the measuring body 18 in the force transmission assembly 10 is converted into an electrical signal and transmitted to the display, and the weight indication is displayed on the display.

[0045] The specific structure of each component of the weighing device 100 and the corresponding relationsh...

Embodiment 2

[0064] Embodiment 2 of the present invention provides a vehicle weighing device, including two weighing devices 100 provided in Embodiment 1, and the specific description is as follows:

[0065] Two weighing devices 100 are arranged side by side and have the same height. When measuring the weight of large equipment such as a crane, one weighing device 100 corresponds to a group of wheels (the left wheel is a group, and the right wheel is a group). The wheel device transmits gravity to the weighing device 100 through the wheels.

[0066] Each measuring body 18 is correspondingly provided with a load cell, and the load cell is a strain gauge, and the strain gauge is fixedly arranged on the side wall of the measuring body 18 for detecting the deformation of the measuring body 18, and the electric signal is transmitted to the display, thereby The weight indication of the device to be tested can be read.

Abstract

The invention discloses a weight measuring device and a vehicle weight measuring device and relates to the technical field of crane detection. The weight measuring device comprises a load-bearing force transmission assembly, weighing sensors and a displayer. The load-bearing force transmission assembly comprises a load-bearing platform, a base body and at least two measuring bodies. The measuringbodies are vertically embedded in the base body. Each measuring body comprises a stress end. The load-bearing platform is arranged above the base body and is abutted against the stress ends. The weighing sensors are fixedly arranged on the measuring bodies and are electrically connected with the displayer through wires. The weight measuring device is ingenious in design, simple in structure, convenient to product and manufacture, simple to operate, accurate to measure, low in cost and high in reliability.

Description

technical field [0001] The invention relates to the technical field of crane detection, in particular to a weighing device and vehicle weighing equipment. Background technique [0002] With the development of science and technology, the market competition of port machinery has become increasingly fierce. At the same time, the overall lightweight of cranes has also been paid attention to. [0003] However, there is a large discrepancy between the design weight of the whole crane and the actual weight of the whole machine, the actual measurement of the crane is difficult, the reliability of the measurement method is poor, and the measurement results obtained are inaccurate, so there is no reliable data reference when designing the overall weight. [0004] To sum up, how to accurately measure the overall weight of a crane is a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] The object of the present invention is to prov...
