[0020] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0021] Example 1
[0022] like Figure 1 As shown, a sensing column limit adjustment mechanism is provided, which includes a slider 1, a left limit adjustment block 4 and a right limit adjustment block 3.
[0023] The slider 1 includes three surfaces, wherein one of the two intersecting inclined surfaces slides in contact with the inclined surface of the left limit adjustment block 4; the other inclined surface slides in contact with the inclined surface of the right limit adjustment block 3; and a connecting sensing post 2 is provided on the surface clamped by the intersecting inclined surfaces.
[0024] like Figure 2 As shown, the left limit adjustment block 4 is fitted with a left limit adjustment screw 6, and the right limit adjustment block 3 is fitted with a right limit adjustment screw 5.
[0025] like Figure 2 As shown, the left limit adjustment block 4 and the right limit adjustment block 3 are both quadrangular prisms with a right-angled trapezoidal bottom surface, and their inclined surfaces slide in contact with the inclined surfaces of the slider 1.
[0026] like Figure 2-3As shown, the sensing column limit adjustment mechanism of this utility model can be set inside the mounting block 7. Specifically, a cavity for accommodating the sensing column limit adjustment mechanism is set inside the mounting block 7. The shape of this cavity is adapted to the shape of the sensing column limit adjustment mechanism. For example, the slider 1 is a pointed house shape (the pointed house shape can be explained as a quadrangular prism with a triangular prism superimposed on it, the quadrangular prism can be a cube, cuboid or other shape) or a triangular prism shape. The left limit adjustment block 4 and the right limit adjustment block 3 are both quadrangular prisms with a right trapezoidal base. An opening is set at the corresponding position of the sensing head of the sensing column. The size of the opening is sufficient to ensure that the sensing head can be exposed when the left limit adjustment block 4 and the right limit adjustment block 3 are adjusted. The internal cavity of the mounting block 7 is also provided with internal threaded holes corresponding to the left limit adjustment screw 6 and the right limit adjustment screw 5.
[0027] The shape limitation of slider 1, left limit adjustment block 4 and right limit adjustment block 3 in this embodiment is only an example. They can also be other shapes. Other shapes can satisfy the condition that the two inclined surfaces of the slider slide in contact with the inclined surfaces of the left limit adjustment block 4 and the right limit adjustment block 3 respectively, and the slider can be moved left and right when the limit adjustment block slides along the slider.
[0028] like Figure 3 As shown, after the sensor column limit adjustment mechanism is installed, tighten the left limit adjustment screw 6 relative to... Figure 2 It can be seen that slider 1 moves the center of sensing column 2 to the right; loosening the left limit adjustment screw 6 and tightening the right limit adjustment screw 5 moves the center of sensing column 2 to the left. By adjusting the screwing depth of the left limit adjustment screw 6 and the right limit adjustment screw 5 in the internal thread hole, slider 1 can be adjusted left and right, thereby adjusting sensing column 2 left and right.
[0029] Example 2
[0030] like Figure 4 As shown, an electric transfer vehicle includes a base frame 8, a top frame 9, and a push rod 10. The base frame 8 and the top frame 9 are connected by a support column 11, and the top frame 9 is connected to the push rod 10. A limiting plate 12 is fixedly connected to the base frame 8. Figure 5 As shown, the sensing column limiting adjustment mechanism described in Embodiment 1 is provided on the limiting plate 12. The mechanism can be configured by directly providing a cavity to accommodate the sensing column limiting adjustment mechanism on the limiting plate 12, or by creating a cavity in the limiting plate to accommodate the mounting block 7, and then integrally mounting the mounting block 7 and the sensing column limiting adjustment mechanism onto the limiting plate 12. A better docking effect can be achieved by adjusting the position of the sensing column.
[0031] For any content not described in detail in this utility model, conventional technical knowledge in the field can be used.

Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
