[0032] In the following examples, the definition of "front, back, left, right" and the like is only for the purpose of indicating the relative relationship, and is not the substantial direction.

[0033] Example, see Figures 1 to 6 The adjustable AGV trolley laser radar fixing support is used for fixing the laser radar on the AGV trolley.

[0034] Specifically:

[0035] The adjustable AGV trolley laser radar fixing support sequentially comprises an upper support 11, a transition support 12 and a lower support 13 from top to bottom. Generally, the upper support 11, the transition support 12 and the lower support 13 are all in the form of a flat plate as a whole. The upper support 11 is integrated with at least two groups of mounting holes 101, and the lower support 13 is fixed on the AGV trolley through screws and the like. The classification of the mounting holes 101 by groups means that each group has a plurality of mounting holes 101, and the positions of the mounting holes 101 correspond to the fixing positions of common laser radars of different brands, so as to facilitate the fixation of different laser radars on the upper support 11 through the corresponding mounting holes 101. In this way, the effect of quick adaptation and installation of the laser radar is achieved.

[0036] The front and rear horizontal adjusting mechanism is arranged between the upper support 11 and the transition support 12, and the left and right horizontal adjusting mechanism is arranged between the transition support 12 and the lower support 13. That is, the horizontal of the upper support 11 in the front and rear direction can be adjusted by the front and rear horizontal adjusting mechanism, and the horizontal of the upper support 11 in the left and right direction can be adjusted by adjusting the transition support 12 through the left and right adjusting mechanism, so that the laser radar as a whole is in a horizontal state. The front and rear horizontal adjusting mechanism and the left and right horizontal adjusting mechanism can adopt various common ways, for example, the corresponding supports are connected by three screws with adjustable length. In this way, the AGV navigation accuracy can be effectively improved.

[0037] Optimized:

[0038] The front and rear horizontal adjusting mechanism of the embodiment is:

[0039] The left side and the right side of the upper support 11 are pivoted to the left side and the right side of the transition support 12 through an upper rotating shaft 21 extending in the left and right direction. That is, the upper support 11 can be high in front and low in back or low in front and high in back relative to the transition support 12.

[0040] The right side of the front side of the transition support 12 is provided with a horizontal upper support plate 121, and the left side is provided with an upper vertical plate 122 extending in the front and rear direction. The front and rear direction means that the upper vertical plate 122 is located in a vertical plane extending in the front and rear direction.

[0041] The front side of the upper support 11 corresponds to the upper support plate 121 and is provided with an upper horizontal pressing plate 111 extending forward, and corresponds to the upper vertical plate 122 and is provided with an upper "U" shaped opening 112 opening downward.

[0042] The upper horizontal pressing plate 111 and the upper support plate 121 are connected by an upper connecting bolt 22, and an upper compression spring 23 is arranged between the upper horizontal pressing plate 111 and the upper support plate 121. Obviously, the upper connecting bolt 22 mainly plays a connecting role rather than a fastening role.

[0043] The upper vertical plate 122 is screwed with an upper adjusting bolt 24, the upper adjusting bolt 24 passes through the upper "U" shaped opening 112, and the upper adjusting bolt 24 and the upper "U" shaped opening 112 are matched. That is, the screw rod of the upper adjusting bolt 24 is clamped in the upper "U" shaped opening 112, and after being tightened, the upper vertical plate 122 and the upper "U" shaped opening 112 can be fixed together. The upper "U" shaped opening 112 is provided with a mark scale line (not shown in the figure) for positioning.

[0044] When in operation, the level meter is placed on the upper support 11; then the upper connecting bolt 22 and the upper adjusting bolt 24 are loosened, the level of the upper support 11 in the front-back direction is adjusted; after being in place, the upper adjusting bolt 24 is tightened, then the nut of the upper connecting bolt 22 is screwed to the appropriate position. Such front-back level adjusting mechanism is simple in operation and has certain shock absorption.

[0045] The left-right level adjusting mechanism is:

[0046] The front side and the rear side of the transition support 12 are pivotally connected to the front side and the rear side of the lower support 13 through a front-back running lower rotating shaft 31. That is, the transition support 12 can be high on the left and low on the right or low on the left and high on the right relative to the lower support 13.

[0047] The right side of the lower support 13 is provided with a horizontal lower support plate 131, and the left side is provided with a lower "U" shaped opening 132 with an opening upward.

[0048] The right side of the transition support 12 is provided with a rightward extending lower horizontal pressing plate 123 corresponding to the lower support plate 131, and the left side is provided with a vertical and left-right running lower vertical plate 124 corresponding to the lower "U" shaped opening 132. The so-called left-right running means that the lower vertical plate 124 as a whole is located in a vertical plane running left and right.

[0049] The lower horizontal pressing plate 123 and the lower support plate 131 are connected by a lower connecting bolt 32, and a lower compression spring 33 is arranged between the lower horizontal pressing plate 123 and the lower support plate 131. Similarly, the lower connecting bolt 32 mainly plays a connecting role rather than a fastening role.

[0050] The lower vertical plate 124 is screwed with a lower adjusting bolt 34, the lower adjusting bolt 34 passes through the lower "U" shaped opening 132, and the lower adjusting bolt 34 and the lower "U" shaped opening 132 are matched. That is, the screw rod of the lower adjusting bolt 34 is clamped in the lower "U" shaped opening 132, and after being tightened, the lower vertical plate 124 and the lower "U" shaped opening 132 can be fixed together. Similarly, the lower "U" shaped opening 132 is provided with a mark scale line (not shown in the figure).

[0051] The adjusting mode of the left-right level adjusting mechanism is similar to that of the front-back level adjusting mechanism, which will not be described again.

[0052] The above is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
