Therefore, the equipment for warehousing AGV maintenance provided by the embodiment is used for lifting the AGV1 conveniently and quickly; and support spacing to longmen stand 12, the focus is stable when guaranteeing to support, makes more succinct when maintaining, maintaining AGV1 to improve logistics transportation efficiency.

The present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

The following describes the apparatus for warehousing AGV maintenance provided in the embodiments of the present application with reference to the accompanying drawings.

Referring to FIGS. 3 and 4 together, FIG. 3 is a perspective view of an apparatus for warehousing AGV maintenance provided by an embodiment of the present invention; the equipment for warehousing AGV maintenance in the embodiment of the application comprises: for supporting the AGV up to the service level with a service device 2. Maintenance equipment 2 supports the height of AGV for making its chassis unsettled, and the drive wheel all can expose with front and back truckle and maintain the change, and the height can be adjusted according to actual use condition.

The apparatus for servicing includes: a movable support frame; the support frame comprises two opposite load-bearing frames 22, and a cross beam 221 is connected to the top between the two load-bearing frames 22, so that the two load-bearing frames 22 are connected into a whole structure through the cross beam 221. And a plurality of traveling wheels 25 are oppositely provided at both sides of the bottom of the support frame. So that the service equipment 2 is supported by the traveling wheels 25 to move to the fault site, and the AGV1 is lifted for service.

After the maintenance facility 2 is moved to the set position, the chassis 11 of the AGV1 needs to be engaged and then lifted. For this purpose, the service device 2 also comprises a lifting assembly. Referring to fig. 3 and 4 together, fig. 4 is a schematic structural diagram of a lifting assembly according to an embodiment of the present invention; the lifting assembly comprises two lifting frames 21 which are oppositely arranged; and each lifting frame 21 is slidably connected with the corresponding bearing frame 22 through a linear bearing 27, so that the lifting frame 21 is lifted and lowered along the vertical direction of the bearing frame 22.

Specifically, when the chassis 11 of the AGV1 is clamped and fixed, the chassis 11 is clamped by a lifting assembly in this embodiment; specifically, each lift frame 21 includes a frame, and a lift assembly pivotally coupled to the frame for raising chassis 11 of AGV 1.

With continued reference to fig. 4 and 5, when the lifting assembly is specifically configured, the lifting assembly has two setting positions, i.e., a dodging setting position and a clamping setting position, and when the lifting assembly rotates to the first setting position, the lifting assembly is configured to press against the chassis 11 of the AGV1 to perform a clamping setting operation; when the lift assembly is pivoted to the second set position, the lift assembly clears the chassis 11 of the AGV1, enabling an avoidance operation.

The lifting assembly includes a lifting swing link 212 vertically disposed and rotatably connected to the frame, and a lifting plate 215 is disposed on the lifting swing link 212 for abutting against the chassis 11 of the AGV 1. The number of the lifting swing rods 212 is four, six, eight, etc., so that the lifting plates 215 at the bottom support the two sides of the bottom of the chassis 11 at multiple points during the rotation of the lifting swing rods 212 at the two sides. Specifically, when the lifting swing links 212 are rotated, the plurality of lifting swing links 212 on the same side are driven to rotate by the horizontally disposed linkage rod 213, so that the lifting plate 215 is rotated between a first setting position and a second setting position. Specifically, a connecting rod is arranged at one end of each lifting swing rod 212 far away from the lifting plate 215, and each connecting rod is rotatably connected with the linkage rod 213; wherein the axis of the lift plate 215 is at an angle of greater than ninety degrees to the axis of the connecting rod. And a handle is arranged at the outer side of the linkage rod 213, and the linkage rod 213 moves to synchronously rotate the plurality of lifting swing rods 212, so that the lifting assembly can be freely switched between a first set position and a second set position.

As can be seen from fig. 3 and 4, the lifting frames 21 on both sides are provided with lifting members, and the lifting members on both sides are opposed to each other and engage with both sides of the bottom of the chassis 11.

As shown in FIG. 6, the lift plate 215 is pressed against the chassis 11 of the AGV1 as the lift assembly is rotated to a first set position. The chassis 11 of AGV1 is restrained against compression by lift plate 215.

As shown in fig. 3 and 7, the load-bearing frames 22 on both sides are not connected by the cross beam 221, and the cross frame is connected to the same end of the load-bearing frames 22 on both sides, so as to enhance the stability of the supporting frame. In lifting and positioning the chassis 11 of the AGV1, the end of the support frame where the cross bar is not mounted is pushed toward the AGV1 while a limit guide wheel 211 is provided at each lifting frame 21 to engage the chassis 11 of the AGV 1. No special calibration is required by the presence of the limit guide wheels 211. The maintenance equipment 2 in this embodiment can be lifted and maintained according to the type of the chassis 11, and only the width matched with the chassis 11 is needed.

After moving the support frame to the appropriate location on the chassis 11 of AGV1, the handles on both sides are pushed to urge the lift plates 215 against the bottom of the chassis 11. In addition, the high height of the gantry uprights 12 of the prior art AGV1 causes the gantry uprights 12 to tilt due to unstable center of gravity when lifting the chassis 11 of the AGV 1. To this end, the support frame and lift assembly of this embodiment also serves to restrain the gantry upright 12 of AGV 1. Specifically, referring to fig. 4 and 8, when the gantry upright 12 is limited, the rubber strip 222 is used on the surface of the beam 221 facing the gantry upright 12, so that the beam 221 is prevented from being damaged when contacting the gantry upright 12. When the lifting component limits the gantry upright post 12, an elbow clamp 214 arranged on the lifting frame 21 is adopted; the elbow clamps 214 are rotatably connected to the two lifting frames 21 in a one-to-one correspondence. The pivotally disposed toggle clamp 214 provides for both an escape and a snap-in limit operation. When the gantry upright post 12 is pressed and limited, the elbow clamp 214 is rotated to enable the rubber blocks on the elbow clamp 214 and the rubber strips 222 on the cross beam 221 to clamp and fix two opposite sides of the gantry upright post 12, so that the lifting process is more stable.

After AGV1 is secured, the drive mechanism in this service facility 2 is used to drive the lifting frames 21 on both sides to move in a vertical direction in unison. As shown in fig. 3 and 9, the drive mechanism includes: and spiral elevating assemblies 23 provided at both sides of the support frame. The two spiral lifting assemblies 23 respectively drive the two lifting frames 21 to lift along the linear bearings 27.

Each spiral elevating assembly 23 includes: a lead screw 232 in screw connection with the lifting frame 21 on the same side, a lifter body 231 for driving the lead screw 232 to rotate, the lifter body 231 having a hand wheel 24; thereby driving the lead screw 232 to rotate in the rotation process of the lifter body 231, and the lead screw 232 drives the lifting frame 21 which is in screw connection with the lead screw to synchronously lift in the rotation process. In another embodiment, the screw elevating assembly 23 may also employ an elevator body 231 which is vertically elevated and the lead screw 232 does not rotate, such that one end of the lead screw 232 is located inside the elevator body 231 and the other end is fixedly connected to the middle portion of the elevating frame 21.

When the lifting frames 21 on both sides are synchronously lifted, the long shafts 26 are synchronously rotatably connected between the two lifter bodies 231. Therefore, when the hand wheel 24 on any side rotates, the lifter bodies 231 on both sides are synchronously driven to drive the corresponding lead screws 232 to move.

As can be seen from the above description, the use of the curb guide wheels 211 positions the support frame above the chassis 11 of the AGV1 during maintenance of the AGV 1. The elbow clamps 214 are matched with the cross beam 221 to limit the gantry upright 12, and the lifting plates 215 of the plurality of lifting swing rods 212 are relatively pressed against two sides of the bottom of the chassis 11. Rotating the handwheel 24 on either side causes the elevator bodies 231 on both sides to synchronously drive the lead screws 232, thereby lifting the chassis 11 of the AGV1 off the ground, exposing the drive wheels 15 and front and rear casters 16, and after being raised to a high position, maintenance can begin immediately.

In this embodiment, chassis 11 that promotes AGV1 through lifting unit rises to the maintenance height along braced frame, and braced frame and lifting unit are spacing to the relative block of longmen stand 12 simultaneously, make longmen stand 12 be difficult for taking place the slope to simple convenient promoting AGV1, reducing maintenance duration, improving logistics transportation efficiency.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
