[0031] Reference is made to the drawingsFigure 1 and Figure 2 As shown in the figure, the embodiment of the present application provides a detection device for realizing the automatic following function of load, which comprises a bellows 1, a floating sensing rod 2 and a sensor 6. One end of the bellows 1 is a load connection end 101, which is used for connecting a load (such as a storage tank). The other end of the bellows 1 is a carrier connection end 102, which is used for connecting a carrier (such as a vehicle head). The load connection end 101 and the carrier connection end 102 are provided with a bellows floating mechanism, which is a flexible mechanism. The floating sensing rod 2 is arranged along the axial direction parallel to the bellows 1. One end of the floating sensing rod 2 is connected and fixed with the load connection end 101 through a mounting bracket 3. The other end of the floating sensing rod 2 floats in the opposite direction with the up-and-down floating of the load connection end 101. The sensor 6 is arranged on the carrier connection end 102, and the sensor 6 faces the floating sensing rod 2, which is used for detecting whether the floating sensing rod 2 is horizontal.
[0032] At present, for the system for realizing the automatic following of load, the problem to be solved is to clearly judge whether the two ends of the bellows 1 are in the horizontal state after adjustment in the adjustment process of the automatic following of load.
[0033] Therefore, in the embodiment, the floating sensing rod 2 is arranged in parallel with the bellows 1, one end of the floating sensing rod 2 is fixed with the load connection end 101 of the bellows 1, so that one end of the floating sensing rod 2 synchronously floats with the up-and-down floating of the load connection end 101, and the other end of the floating sensing rod 2 floats in the opposite direction with the floating of the load connection end 101. Thus, it is not difficult to imagine that when the load connection end 101 is connected with the load, with the increase of the weight of the load, the load connection end 101 will sink due to the weight, and the carrier connection end 102 will not change in displacement because it is connected with the carrier. At this time, the whole bellows 1 appears to be curved under the connection of the bellows floating mechanism. Under the condition of the increase of the load, the end of the floating sensing rod 2 connected with the load connection end 101 synchronously sinks with the load connection end 101, and the other end of the load connection end 101 appears to float upward and is out of the detection range of the sensor 6. When the bellows 1 appears to be curved, the system will adjust the height of the load through the automatic adjustment mechanism, so that the load connection end 101 and the carrier connection end 102 keep the same height. When the automatic adjustment mechanism adjusts the height of the load, the load connection end 101 floats upward, so that the end of the floating sensing rod 2 connected with the load connection end 101 also gradually floats upward, so that the other end of the floating sensing rod 2 gradually sinks, and finally the floating sensing plate returns to the detection range of the sensor 6, so as to reflect that the bellows 1 is adjusted to the horizontal state.

[0035] In the above embodiment, the flexible connection between the load connecting end 101 and the carrier connecting end 102 is formed by arranging the connecting hose 1031 between the load connecting end 101 and the carrier connecting end 102, and the elastic recovery of the deformed bellow 1 during adjustment is realized by arranging the floating adjusting shaft 1033 between the two floating mechanism flange end covers 1032.
[0036] In an embodiment, as shown in the figures, Figure 1 and Figure 2 The outer periphery of the floating mechanism flange end cover is arranged with a plurality of holed lugs, and the floating adjusting shaft 1033 is locked on the holed lugs by elastic pads and nuts.

[0040] In an embodiment, the stand body is provided with a through hole, and the floating sensing rod 2 passes through the through hole and is locked at both ends by fastening nuts.
[0041] It can be understood that in the above embodiment, the floating sensing rod 2 is fixed with the mounting bracket 3 through bolts, so that the connection and fixation between the floating sensing rod 2 and the mounting bracket 3 can be realized conveniently.
[0042] In an embodiment, as shown in the figures, Figure 1 andFigure 2 As shown in the figure, the floating induction rod 2 is connected with the carrier connecting end 102 through the limiting support 4, wherein the limiting support 4 comprises a support fixed plate connected with the carrier connecting end 102, and the support fixed plate is provided with a limiting block, and the limiting block is provided with a waist-shaped hole in the vertical direction, and the floating induction rod 2 is limited to float up and down in the waist-shaped hole.
[0043] In the above embodiment, the floating induction rod 2 is installed to the carrier connecting end 102 through the limiting support 4, and the waist-shaped hole is arranged on the limiting support 4, which plays a guiding and limiting role for the floating of the floating induction rod 2, thereby ensuring the guiding of the floating of the floating induction rod 2.
[0044] In an embodiment, the limiting block is provided with a sensor 6 mounting plate 5, the sensor 6 mounting plate 5 is provided with a mounting through hole, the sensor 6 is mounted in the mounting through hole, and the detection end of the sensor 6 is blocked by the floating induction rod 2 when the floating induction rod 2 is in a horizontal state.
[0045] In the above embodiment, the installation and fixation of the sensor 6 can be realized by arranging the sensor 6 mounting plate 5, and the installation position of the sensor 6 can be limited by using the sensor 6 mounting plate 5, so that the sensor 6 can detect the floating induction rod 2 within a range.
[0046] In an embodiment, as shown in Figure 1 and Figure 2 As shown, the limiting support 4 is provided with a plurality of lightening holes, and it can be imagined that the weight of the limiting support 4 can be reduced through the lightening holes.
[0047] Based on the above content, the detection device for realizing the automatic load following function provided by the embodiment of the application realizes the working process of the automatic load following as follows.
[0048] Firstly, the sensor detects the load position, and if the load is outside the sensor sensing range, a signal is sent to the background control system, the background control system sends a command to adjust the position, the automatic adjustment mechanism receives the adjustment command, and through the control system, the load position is moved up or down, and the load position stops after moving up or down to a new position, the sensor re-detects the load position, and if the load is outside the sensor sensing range, a signal is continuously sent to the background control system, and the process is repeated until the sensor detects the signal, and the automatic load following is completed.
