[0026] The utility model will be explained in detail as follows.

[0027] As Figures 1-6 shown:

[0028] A goods shelf device suitable for automatic loading and unloading of a knapsack type transport robot, comprising a goods frame 1 for carrying goods, a support assembly 2 installed at the bottom of the goods frame 1 and hinged with the goods frame 1, and a driving device 3 installed on the goods frame 1 and used for controlling the expansion and contraction of the support assembly 2.

[0029] In use, the support assembly 2 supports the goods frame 1, and the goods are loaded into the goods frame 1;

[0030] The bottom of the goods frame 1 is supported by the transfer equipment, and the entire goods shelf is lifted; the transfer equipment can be a forklift or a carrying robot in the prior art;

[0031] The support assembly 2 is contracted by the driving device 3;

[0032] The transfer device controls the goods shelves to descend, and reduces the distance between the goods shelves and the floor;

[0033] When descending to the specified height, the rotating device transports the goods shelves;

[0034] When being transported to the specified position, the transfer device lifts the goods shelves; the support assembly 2 is controlled to extend through the driving device 3;

[0035] The transfer device controls the goods shelves to descend again, and the bottom of the support assembly 2 acts on the floor to support the goods shelves;

[0036] The transfer is completed, and the goods are unloaded.

[0037] In the utility model, the extension and retraction of the support assembly 2 are controlled through the driving device 3, so that the distance between the gravity center of the goods shelves and goods and the floor is reduced in the transfer process, the problem that the goods shake or slip in the transfer process is avoided, and the goods are prevented from being damaged due to shaking or slipping in the transfer process.

[0038] In some possible embodiments, in order to effectively support the goods frame 1, the support assembly 2 comprises two groups of support pieces which are symmetrically arranged along the X-axis direction and are hinged to the bottom of the goods frame 1; the two groups of support pieces are respectively in transmission connection with the driving device 3;

[0039] The support piece comprises two groups of support legs 21 which are hinged to the bottom of the goods frame 1 and are symmetrically arranged along the Y-axis, and a hinge arm 22 which is arranged between the two groups of support legs 21 and is hinged to the two groups of support legs 21 at two ends; one group of the support legs 21 is in transmission connection with the driving device 3; a hinge seat 2121 is mounted on the support leg 21, and the hinge arm 22 is hingedly matched with the hinge seat 2121.

[0040] The four groups of support legs 21 effectively support the goods frame 1;

[0041] Specifically, when the driving device 3 drives the support legs 21 in the support piece to shrink, since the two ends of the hinge arm 22 are respectively hinged to the support legs 21, the hinge arm 22 is driven to shrink when one group of the support legs 21 shrinks, so that the other group of the support legs 21 is also driven to shrink; the two groups of support legs 21 are synchronously shrunk, so that the shrinking height is consistent; conversely, the extension can be realized;

[0042] Through the synchronous extension and retraction of the two groups of support pieces driven by one group of the driving device 3, the support for the goods shelves is more stable, and the operation is more simple and convenient;

[0043] In some possible implementation manners, in order to effectively realize the hinging of the support leg 21 and the goods frame 1, the support leg 21 comprises a hinge seat 211 mounted on the bottom of the goods frame 1 and a support leg 212 connected with the hinge seat 211; and the end of the hinge arm 22 is hinged with the support leg 212.

[0044] When the goods frame 1 is supported, the support leg 212 is arranged along the Z-axis direction, that is, the included angle A between the support leg 212 and the plane on which the bottom of the goods frame 1 is located is 90°; and during the transfer process, the included angle A between the support leg 212 and the plane on which the bottom of the goods frame 1 is located is an acute angle.

[0045] In some possible implementation manners, the driving device 3 comprises two groups of pull ropes 31, one end of each group of pull ropes 31 being connected with one group of support legs 212 in the two groups of support members and being located on the bottom of the goods frame 1, a winch 32 rotatably mounted on the bottom of the goods frame 1 and being located between the two groups of support members, a driving motor 33 in transmission connection with the winch 32 and used for controlling the rotation of the winch 32, and elastic connecting members 34 connected with the support legs 212 and the goods frame 1 respectively, and the other ends of the two groups of pull ropes 31 being connected with the winch 32.

[0046] The axis of the winch 32 is arranged along the X-axis direction, and the distance between the two groups of support members and the axis of the winch 32 is equal; the winch 32 is driven to rotate around the X-axis direction by the driving motor 33, so as to drive the two groups of pull ropes 31 to be retracted or to be unwound from the winch 32;

[0047] Specifically, the two groups of pull ropes 31 are wound on the winch 32 in the same direction, one end of one group of pull ropes 31 is connected with one group of support legs 212 in one group of support members after passing through the bottom of the winch 32, and the other end of the other group of pull ropes 31 is connected with one group of support legs 212 in the other group of support members after passing through the top of the winch 32; and the two groups of support legs 212 connected with the pull ropes 31 are arranged on the same side.

[0049] One end of the elastic connecting member 34 is connected with the support leg 212 close to the winch 32, and the other end is connected with the goods frame 1.

[0050] When the support leg 212 is upright to support the goods frame 1, the elastic connecting member 34 is arranged obliquely and forms an acute angle with the Z-axis direction, and the elastic connecting member 34 is in an initial state at this time.

[0051] When the legs 212 are retracted, the elastic connecting member 34 will be in a stretched state; so that when the legs 212 are restored from the retracted state to the upright state, the elastic connecting member 34 will exert an elastic force on the legs 212 to restore them to the upright state, effectively supporting the goods frame 1;

[0052] Further, the elastic connecting member 34 is a spring;

[0053] In some possible embodiments, in order to effectively realize the retraction of each group of legs 212 towards the side close to the winch 32, the hinged seat 211 is arranged on the side of each group of legs 212 close to the winch 32.

[0054] In some possible embodiments, the goods frame 1 comprises a bottom plate 11 connected with the support, a plurality of groups of supports 12 arranged on the bottom plate 11 in the Z-axis direction, and a plurality of groups of fences 13 arranged between adjacent two groups of supports 12 and cooperating with the bottom plate 11 to form a goods compartment.

[0055] Each group of fences 13 is detachably connected with the adjacent two groups of supports 12;

[0056] Further, the top of the fence 13 is provided with a latch 131, and the support 12 is provided with a hole for cooperating with the latch 131; a pin shaft 132 is arranged on the side of the fence 13 close to the support 12, and the support 12 is provided with a pin hole for cooperating with the pin shaft 132; when there are four groups of fences 13, four groups of pin holes are arranged at equal intervals in the Z-axis direction, and the distance between the adjacent two groups of pin holes is greater than the thickness of the fence 13; in this way, the four groups of fences 13 can be stacked on the support 12.

[0057] In some possible embodiments, the winch 32 is rotatably installed on the bottom plate 11, a guide pipe for sleeving the pull rope 31 is arranged on the bottom plate 11, one end of the pull rope 31 is connected with the winch 32 through the guide pipe and the other end is connected with the leg 212 away from the winch 32 through the guide pipe; one end of the elastic connecting member 34 is connected with the bottom plate 11;

[0058] The arrangement of the guide pipe will make the pull rope 31 not rub against the bottom plate 11, avoiding damage caused by long-term wear and tear of the pull rope 31.
