Embodiment 1

[0033] An embodiment of the present invention provides a strength detection device, which is used to detect the strength of the lower protective device to be tested, such as figure 1 Shown is a structural block diagram of a strength testing device, which includes: a mechanical hydraulic device 10, an electrical control cabinet 20, and an upper computer 30; wherein, the mechanical hydraulic device 10 accepts the lower protective device after being tested; the electrical control cabinet 20 and the upper computer The machine 30 is wirelessly connected; the mechanical hydraulic device 10 is connected with the electrical control cabinet 20.

[0034] Specifically, the mechanical hydraulic device includes a hydraulic system and a multi-channel hydraulic cylinder assembly, and each hydraulic cylinder assembly is provided with a valve; the hydraulic system includes a hydraulic pump and a common rail module, such as figure 1 The shown hydraulic cylinder assembly 101, hydraulic pump 102,...

Embodiment 2

[0074] Corresponding to the strength detection equipment provided in the above embodiment, the embodiment of the present invention also provides a strength detection method, which is applied to the strength detection equipment described in the first embodiment above, to detect the strength of the lower protective device to be tested, Such as Image 6 A flow chart of a strength detection method shown, the method includes the following steps:

[0075] Step S602, when the upper computer monitors that the installation of the lower protective device to be tested is completed, it sends the loading parameters to the electrical control cabinet;

[0076] Step S604, the electrical control cabinet receives the loading parameters, and controls the loading mode of the mechanical hydraulic device according to the loading parameters, so that the mechanical hydraulic device can detect the strength of the lower protective device to be tested according to the detection instruction; and, when th...

Abstract

The invention provides strength detection equipment and method, and relates to the technical field of strength detection. The equipment comprises a mechanical hydraulic device, an electrical control cabinet and an upper computer; the upper computer is used for sending a loading parameter to the electrical control cabinet when the condition that installation of a bottom rear-part protection deviceis completed is monitored; the electrical control cabinet is used for receiving the loading parameter, and controlling the loading mode of the mechanical hydraulic device according to the loading parameter, and thus the mechanical hydraulic device detects the strength of the bottom rear-part protection device according to a detection command; when the mechanical hydraulic device is completely loaded, a completion signal is sent to the upper computer; and a strength detection report corresponding to the detection command is generated. According to the strength detection equipment and method provided by the invention, the performance of the bottom rear-part protection device can be detected on the spot, and the usage security can be enhanced.

Description

technical field [0001] The invention relates to the technical field of strength detection, in particular to a strength detection device and method. Background technique [0002] Since most trucks in the past did not have a good rear lower protection device, in the event of a rear-end collision, it is easy to cause the passenger car to get into the rear of the truck, resulting in a very high proportion of casualties for the driver and crew members in the passenger car. Therefore, Usually adopt the way that the rear lower protective device of truck is installed forcibly, when avoiding rear-end collision accident, the harm that passenger car drills into the rear of truck is caused. [0003] However, due to the lack of necessary testing equipment, the strength detection of the protective device at the rear lower part of the truck has become a difficult point in the vehicle safety inspection work at this stage. When the safety performance of the protective device is inspected on...
