As shown in fig. 16, the difference between this embodiment and embodiment 3 is that the first layer of finger 11 further includes a plurality of fixing finger, each of the fixing finger includes at least two finger bodies 32 arranged parallel to each other, and the second finger body 32 is provided with a second locking clamping plate device 22 for fixing the stand.
In this embodiment, the second finger body 32 is a box-shaped beam, and the second locking clamp device 22 may refer to the "automatic locking clamp device for finger" of chinese patent application No. CN 201520730349.0.
The fixed fingerboard is used for discharging the stand with fixed specification, and when the fixed fingerboard is used, the stand is placed between two adjacent fingerboard bodies II 32, and the locking clamping plate device II 22 is adjusted to fix the stand.
The adjustable fingerboard further comprises a middle fingerboard 12, the middle fingerboard 12 is arranged between the first layer fingerboard 11 and the second layer fingerboard 13, the middle fingerboard 12 comprises a plurality of fingerboard bodies III 33, and locking clamping plate devices III 23 are arranged on the fingerboard bodies III 33. As shown in fig. 14 to 15, the middle finger 12 is hinged to the derrick 14, and the middle finger 12 can rotate around a hinge point to switch between a horizontal working state and a vertical storage state. In this embodiment, the middle fingerboard 12 is hinged to the derrick 14 through a driving device 72, the driving device 72 is an air cylinder, a hydraulic cylinder or an electric cylinder, one end of the driving device 72 is hinged to the middle fingerboard 12, and the other end of the driving device 72 is hinged to the derrick 14.
In this embodiment, the third finger body 33 is a box-shaped beam, and the third locking clamp device 23 may refer to "an automatic locking clamp device for a finger" of chinese patent application No. CN 201520730349.0.
The specific operation method comprises the following steps: when the middle fingerboard 12 is required to be used, the cylinder rod of the driving device 72 is adjusted to extend out, so that the middle fingerboard 12 rotates to a horizontal position around a hinge point, is switched to a horizontal working state and is used for supporting a standing root with poor rigidity, and is locked by the locking clamping plate device III 23, so that the deflection deformation generated by the locking clamping plate device III is reduced; when the middle fingerboard 12 is not needed, the cylinder rod of the driving device 72 is adjusted to retract, so that the middle fingerboard 12 is driven to rotate to the vertical position around the hinge point, the vertical storage state is switched, and the occupied space is released.
The middle finger 12 comprises a plurality of adjustable fingers and/or a plurality of fixed fingers, which can be well matched with the first layer finger 11 and the second layer finger 13 for discharging the vertical roots.
Example 7
The difference between this embodiment and embodiment 6 is that one end of the first finger body 31 is connected to the derrick 14, and the other end of the first finger body 31 is provided with a proximity switch for monitoring the status of the end clamping plate in real time; similarly, one end of the second finger body 32 is connected with the derrick 14, and the other end of the second finger body 32 is provided with a proximity switch for monitoring the state of the end clamping plate in real time; one end of the third finger body 33 is connected with the derrick 14, and a proximity switch for monitoring the state of the end clamping plate in real time is arranged at the other end of the third finger body 33. The proximity switch includes a switching element, a cable, and a switch mount.
The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the utility model.
