[0046] The working principle of the pressure detection device for processing accessories of mining trackless rubber-tyred vehicles provided by the present invention is as follows:

[0047] Working principle: The feeding conveying mechanism 2 conveys the carriage frame to be inspected to the conveying roller 703 on the accessory lifting structure 7 in the inspection frame 4, and the lifting rod 701 contracts, thereby driving the support frame 702 to descend, and then descending together with the carriage frame placed on the conveying roller 703, and fixing the carriage frame in the inspection frame 4 through the accessory support 5, and marking the position where pressure detection is required with a marking pen (or marking the carriage frame before it is transported to the inspection frame 4), and after the high-speed monitoring camera 21 detects the marked point, the controller 36 controls the pressure sensor The pressure block 20 of the device 19 moves to the corresponding marked point, and the telescopic rod 15 drives the pressure block 20 to move downward continuously to apply pressure to the car frame. At this time, the pressure sensor 19 transmits the pressure data to the controller 36 and records it in real time. The multiple displacement sensors 8 located at the bottom of the car frame transmit the data of deformation or displacement at different positions of the car frame to the controller 36 and record it. Finally, the detection data is displayed on the controller 36. The display data of the detection data under continuous pressure can accurately obtain the situation of the car frame under different pressures, thereby improving the measurement efficiency and accuracy.

[0048] Embodiment 2: Based on the specific embodiment 1, the difference of this embodiment is that:

[0049] like Figure 6-8 As shown, an adjusting threaded column 24 penetrating the adjusting disk 16 is fixed on the top of the connecting disk 17, a locking nut 25 is threadedly connected to the top of the adjusting threaded column 24, and an arc guide groove 26 cooperating with the adjusting threaded column 24 is provided on the adjusting disk 16. When the pressure block 20 does not fit the required detection position, it can be adjusted by loosening the locking nut 25 to ensure that the multiple pressure sensors 19 fit the detection point or surface, thereby improving the accuracy of the detection result.

[0050] The pressure block 20 is hinged to the bottom end of the connecting shaft 18, and there are several pressure sensors 19, which are all installed at the bottom of the pressure block 20. Limiting protrusions inclined toward the cross-shaped bracket 27 are set at both ends of the pressure block 20. The high-speed monitoring camera 21 and the buffer spring 22 are installed on the outer circumferential surface of the connecting shaft 18 through the cross-shaped bracket 27. The end of the buffer spring 22 away from the cross-shaped bracket 27 is fixedly connected to the top of the pressure block 20, and can automatically adjust when pressure is applied according to changes in the detection position and angle, so that the pressure block 20 fits the detection position. After the detection is completed, the pressure block 20 returns to its original position under the action of the buffer spring 22 (the limiting protrusion can form a buffer cavity at one end between the cross-shaped bracket 27 and the pressure block 20 when the buffer spring 22 is compressed, leaving enough deformation gap for the buffer spring 22 to avoid the situation where the spring itself loses its elastic deformation due to the pressure being greater than the maximum force that the spring can withstand within its own deformation range), which is convenient for the subsequent pressure detection to continue, without manual adjustment, reducing labor intensity and improving detection efficiency.

[0051] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
