[0024] As attached Figure 1 To the attached Figure 3 As shown:

[0025] The utility model provides a trolley positioning mechanism, comprising a base plate 1, a positioning cylinder 2 is installed at the middle position of the top of the base plate 1, a pair of first mounting plates 3 are installed at the positions on both sides of the positioning cylinder 2 on the top of the base plate 1 through brackets, a plurality of guide wheels 4 are installed on the top of each first mounting plate 3, a pair of first mounting seats 5 and a pair of second mounting seats 6 are symmetrically installed on both sides of the top of the base plate 1, a pair of first mounting seats 5 and a pair of second mounting seats 6 are installed on opposite sides, a pair of lateral limit blocks 7 are symmetrically installed on the top of the pair of second mounting seats 6 on opposite sides, a pair of lateral position detectors 8 are symmetrically installed on the top of the opposite side, a pair of second mounting plates 9 are symmetrically installed on the other side of the top of the base plate 1, a plurality of rearward limit blocks 10 are installed on the top of the second mounting plate 9, and a rearward position detector 11 is installed on the top of the second mounting plate 9 through a bracket.

[0026] Among them, a slope is provided on one side of the base plate 1 to facilitate pushing the trolley onto the base plate 1.

[0027] Among them, fixing bolts 12 are installed at the edge of the top end of the base plate 1 to facilitate fixing the base plate 1.

[0028] The positioning cylinder 2 is detachably connected to the base plate 1 , so that the trolley can be squeezed and fixed by extending the output end of the positioning cylinder 2 .

[0029] The first mounting plate 3 is detachably connected to the base plate 1 , so that the first mounting plate 3 can be removed and the guide wheel 4 can be cleaned and maintained.

[0030] The first mounting seat 5 is detachably connected to the base plate 1 , so that the first mounting seat 5 can be removed and the lateral limit block 7 can be cleaned and maintained.

[0031] The second mounting base 6 is detachably connected to the base plate 1 , so that the second mounting base 6 can be removed and the lateral limit block 7 and the lateral position detector 8 can be cleaned and maintained.

[0032] The second mounting plate 9 is detachably connected to the base plate 1 , so that the second mounting plate 9 can be removed and the rearward limit block 10 and the rearward in-position detector 11 can be cleaned and maintained.

[0033] The working principle of this embodiment is as follows: when using the trolley positioning mechanism, the staff first pushes the trolley onto the base plate 1 along the slope on one side of the base plate 1. The guide wheel 4 can assist the trolley in moving and can roughly position the trolley. At this time, the staff continues to push the trolley until the trolley hits the rear limit block 10, so that the rear position detector 11 detects that the trolley is in place and feeds back to the control system. The control system controls the output end of the positioning cylinder 2 to automatically extend and make the side of the output end of the positioning cylinder 2 push the trolley to close to the lateral limit block 7. At this time, the lateral position detector 8 detects that the trolley is in place laterally. At this time, the lateral position detector 8 and the rear position detector 11 simultaneously detect the positioning of the trolley, and the main control system determines that the trolley has completed precise positioning. This mechanism is equipped with a closed-loop detection to ensure that the state of the trolley is controllable during the entire positioning process, and the positioning cylinder 2 is always in an extended state to ensure that the trolley remains in its current state after manual release. After the loading and unloading work is completed, the positioning cylinder 2 automatically retracts so that the staff can push the trolley down.
