[0038] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0039] First embodiment

[0040] like Figure 1-Figure 15 As shown, the intelligent robot for warehousing and transportation of the first embodiment of the utility model includes:

[0041] A travel assembly 1, the travel assembly 1 comprises a frame 11, wheels 12 and a drive unit 13, the wheels 12 and the drive unit 13 are both arranged on the frame 11, and the drive unit 13 drives the wheels 12 to rotate around their own axis;

[0042] A fixed frame, the fixed frame includes a support frame 2 horizontally arranged above the vehicle frame 11 and a surrounding frame 3 vertically arranged on the support frame 2;

[0043] A movable frame includes a storage rack 4 and an intercepting rack 5, both of which are consistent with the width direction of the carrier frame 2. The intercepting rack 5 rotates around its own width direction at one end of the storage rack 4. The storage rack 4 is connected with a rolling member 6, and the rolling member 6 rolls between the carrier frame 2 and the frame 11 along the length direction of the carrier frame 2; a locking assembly 7 is arranged between the storage rack 4 and the intercepting rack 5 to lock the two at two stations. At the first station, the storage rack 4 and the intercepting rack 5 have the same length direction. At the second station, the intercepting rack 5 is perpendicular to the length direction of the storage rack 4 and extends upward. The locking assembly 7 is also used to lock the intercepting rack 5 at the second station on the carrier frame 2. In the locked state, the intercepting rack 5 and the surrounding rack 3 cooperate with each other to surround the upper part of the carrier frame 2.

[0044] In this embodiment, the specific structure of the travel component 1 is as follows: Figure 5 and Figure 6 As shown, the frame 11 in the travel component 1 includes a base frame 111 and a top plate 112 fixed directly above the base frame 111. The projections of the base frame 111 and the top plate 112 on the horizontal plane are both rectangular. Two pairs of wheels 12 are provided, which are respectively located on both sides of the base frame 111. The two pairs of wheels 12 include front wheels and rear wheels adjacent to both ends of the base frame 111. The wheels 12 rotate around their own axis lines on the sides of the base frame 111. Two drive units 13 are provided, which are connected to the two pairs of wheels 12 in a one-to-one correspondence.

[0045] After the travel component 1 adopts the above structure, the two pairs of wheels 12 can be driven to rotate through two relatively independent driving units 13. When the rotation speeds of the two pairs of wheels 12 are consistent, the frame 11 keeps going straight. When the rotation speeds of the two pairs of wheels 12 are inconsistent, the frame 11 turns. Since the two pairs of wheels 12 rotate separately through the two independent driving units 13, the frame 11 can make a sharp turn, reduce the turning radius, and improve the turning efficiency.

[0046] The driving unit 13 specifically includes a driving motor 131, a driving wheel 132, a driven wheel 133 and a crawler track 134, wherein the housing of the driving motor 131 is fixed on the base frame 111, the output shaft is fixedly connected to the driving wheel 132 coaxially, the driving wheel 132 and the driven wheel 133 are respectively fixedly connected to the front wheel and the rear wheel coaxially, and the driving wheel 132 is transmission-connected to the driven wheel 133 via the crawler track 134.

[0047] After adopting the above structure, the driving motor 131 runs, driving the active wheel 132 to rotate, and the active wheel 132 acts on the driven wheel 133 through the track 134, so that the driven wheel 133 rotates. Since the active wheel 132 and the driven wheel 133 are respectively connected to the front wheel and the rear wheel coaxially, the two wheels 12 rotate synchronously, thereby realizing the driving movement of the frame 11.

[0048] In the fixed frame, the supporting frame 2 is arranged directly above the top plate 112. The overall structure of the supporting frame 2 is a rectangular plate structure. Three surrounding frames 3 are arranged, two of which are vertically arranged above the two sides of the supporting frame 2, and the remaining one is vertically arranged above one end of the supporting frame 2, so that a gap is formed above the other end of the supporting frame 2.

[0049] In the movable frame, the storage rack 4 and the intercepting rack 5 are in the same width direction as the supporting rack 2, one end of the intercepting rack 5 is rotatably connected to one end of the storage rack 4 and the relative rotation axis is parallel to the width direction of the two, the end of the storage rack 4 away from the intercepting rack 5 rolls on the supporting rack 2 through the rolling member 6, and a locking assembly 7 is provided between the storage rack 4 and the intercepting rack 5, which can flexibly adjust the position and angle of the storage rack 4 and the intercepting rack 5 according to the use requirements of the device.

[0050] Specifically, when loading and unloading cargo is required, the device is adjusted to Figure 1 and Figure 2 In the rotation state shown, the intercepting frame 5 is in the first working position and is locked by the locking assembly 7. In this working position, the intercepting frame 5 and the storage rack 4 are in the same length direction and are located in the same plane. The rolling member 6 rolls on the supporting frame 2, so that the rolling member 6 moves to the bottom of the above-mentioned notch, and then the end of the intercepting frame 5 away from the storage rack 4 is placed on the ground. At this time, the movable frame composed of the intercepting frame 5 and the storage rack 4 forms a slope. Workers can push the cargo shelves on the ground to the top of the supporting frame 2 through the slope, and can also push the cargo shelves above the supporting frame 2 to the ground through the slope. In this way, the loading and unloading operations of the cargo shelves can be completed conveniently, and the loading and unloading efficiency can be improved through convenient operations that save time and effort.

[0051] When the cargo shelves are stored on the carrier frame 2 and need to be transported, the intercepting frame 5 is adjusted to the second working position, and the locking assembly 7 is used to lock the working position while locking the intercepting frame 5 on the carrier frame 2. At this time, the storage rack 4 is located between the frame 11 and the carrier frame 2, and the intercepting frame 5 fills the gap of the three surrounding frames 3, that is, the intercepting frame 5 and the three surrounding frames 3 are arranged on the four sides above the carrier frame 2, thereby preventing the cargo shelves on the carrier frame 2 from falling and realizing safe transportation.

[0052] A further improvement is that a steering assembly 8 is provided between the frame 11 and the fixed frame, and the steering assembly 8 drives the fixed frame to rotate, and the rotation axis of the fixed frame extends along the vertical direction; the steering assembly 8 includes a steering motor 81 and a bearing 82, the casing of the steering motor 81 is fixed on the frame 11, and the output end is connected to the fixed frame, one of the inner ring and the outer ring of the bearing 82 is connected to the fixed frame, and the other is connected to the frame 11.

[0053] Specifically, the housing of the direction-adjusting motor 81 is fixed on the bottom frame 111, the output shaft passes through the top plate 112 and is fixedly connected to the carrier frame 2, and the outer ring of the bearing 82 is fixedly connected to the carrier frame 2, and the inner ring is fixedly connected to the top plate 112. After adopting the above structure, the direction-adjusting motor 81 can drive the top plate 112 to rotate, so that the top plate 112 and the surrounding frame 3 rotate stably under the action of the bearing 82, and the direction position of the carrier frame 2 can be flexibly adjusted according to the loading and unloading position of the device and the goods, without deliberately aligning the gaps formed by the three surrounding frames 3 above the carrier frame 2 with the loading and unloading position, so that the loading and unloading of the cargo shelves is convenient, which is conducive to improving the transportation efficiency.

[0054] A further improvement is that the storage rack 4 and / or the intercepting rack 5 is provided with support rollers 9 whose axes are parallel to the width direction of the fixed rack. The support rollers 9 rotate around their own axis and are closely distributed along the length direction of the storage rack 4 or the intercepting rack 5 where they are located.

[0055] Specifically, the storage rack 4 and the interception rack 5 are both adjacently provided with support rollers 9 extending axially along the width direction of the two. The support rollers 9 are arranged around their own axis, so that the interception rack 5 can be adjusted and locked to the position as shown in FIG. Figure 1 and Figure 2 When in the first workstation position shown, the friction force on the cargo rack passing through the movable frame is reduced, making loading and unloading of the cargo rack more convenient and labor-saving, thereby improving transportation efficiency.

[0056] A further improvement is that the rolling member 6 includes a roller 61 , the storage rack 4 is sleeved outside the roller 61 , the support rack 2 is provided with a strip opening 221 extending along its own length direction, and the roller 61 is passed through the inner side of the strip opening 221 .

[0057] The specific structure of the rolling element 6 is as follows Fig.14 and Fig.15As shown, both ends of the roller 61 are provided with a limit plate 62, and a ball 63 is protruded from a side of the limit plate 62 adjacent to the guide rail 22, and the ball 63 rotates around its own ball center. The limit plate 62 includes an inner plate 621 and an outer plate 622. The inner plate 621 is provided with a first through hole distributed in a circular array, and the outer plate 622 is provided with a second blind hole distributed in a circular array. The first blind hole and the second blind hole are combined in a one-to-one correspondence to form a ball center angle greater than 180° and less than 360°

[0058] The inner plate 621 , the outer plate 622 and the roller 61 are fixedly connected by bolts 64 .

[0059] Correspondingly, the supporting frame 2 includes a bottom plate 21 arranged above the frame 11 and guide rails 22 arranged on both sides of the bottom plate 21 and in the same length direction as the strip opening 221, and also includes a pressure plate 24 fixed above the bottom plate 21. When the surrounding frame 3 is locked and connected with the intercepting frame 5, the storage rack 4 is located between the pressure plate 24 and the bottom plate 21.

[0060] Specifically, Figure 7-10 As shown, in the carrier frame 2, the bottom plate 21 is fixed to the top end of the output shaft of the adjustment motor 81 and is fixedly connected to the outer ring of the bearing 82. The bottom plate 21 is a rectangular plate, and guide rails 22 are fixed on the upper sides and are distributed side by side along the width direction of the bottom plate 21. The guide rails 22 are vertically arranged and integrally formed with a strip opening 221 extending along their own length direction. The two ends of the strip opening 221 extend to be adjacent to the two ends of the guide rails 22. The width of the strip opening 221 is consistent with the outer diameter of the roller 61. The pressure plate 24 is fixed between the two guide rails 22, and the top surface of the pressure plate 24 is fixedly connected to the surrounding frame 3; the roller 61 is penetrated by the inner side of the strip opening 221, the inner disk 621 is located between the outer disk 622 and the guide rail 22, the ball 63 abuts against the guide rail 22, and the two sides of the storage rack 4 are respectively fitted with the two guide rails 22, and the sealing sleeve at the end of the storage rack 4 away from the interception rack 5 is arranged outside the roller 61.

[0061] After adopting the above structure, the roller 61 is passed through the inner side of the strip opening 221 and the outer diameter of the roller 61 is consistent with the width of the strip opening 221, so that the storage rack 4 can be conveniently moved along the length direction of the strip opening 221, and the storage rack 4 is sleeved outside the roller 61, so that when the storage rack 4 drives the roller 61 to slide to the end position of the strip opening 221, the angle direction of the storage rack 4 can be adjusted; and the storage rack 4 is fitted between the two guide rails 22, and the ball 63 abuts against the guide rail 22, which ensures the smooth movement of the storage rack 4 and reduces the friction force on the storage rack 4 when it moves.

[0062] A further improvement is that a support roller 23 extending axially along the length direction of the bottom plate 21 is provided above the bottom plate 21, and the support roller 23 rotates on the bottom plate 21 around its own axis, and the support roller 23 is used to support the storage rack 4. When the storage rack 4 moves between the bottom plate 21 and the pressure plate 24, the wheel surface of the support roller 23 contacts the bottom surface of the storage rack 4, so as to facilitate the support of the storage rack 4 and ensure the smooth movement of the storage rack 4.

[0063] A further improvement is that a rotating recess 41 and a rotating protrusion 51 which are matched and extend along the width direction of the fixed frame are provided between the storage frame 4 and the intercepting frame 5, and the cross section of the rotating recess 41 is circular.

[0064] Specifically, Fig.12 and Fig.13 As shown, the rotating recess 41 is arranged at the end of the storage rack 4 away from the rolling element 6, and the rotating protrusion 51 is arranged at the end of the intercepting rack 5 adjacent to the storage rack 4, and the rotating protrusion 51 is adapted to the rotating recess 41 to realize the rotating connection between the intercepting rack 5 and the storage rack 4.

[0065] A further improvement is that a first locking hole 42 is provided at the bottom of the rotating recess 41, a second locking hole 52 extending along the length direction of the rotating protrusion 51 is provided, a third locking hole 222 is provided on the fixing frame, the second locking hole 52 and the third locking hole 222 are both through holes, the locking assembly 7 includes a locking pin 71, and the first locking hole 42, the second locking hole 52 and the third locking hole 222 are plugged in and matched through the locking pin 71.

[0066] Specifically, the third locking hole 222 is provided on the guide rail 22, and the cross-sections of the first locking hole 42, the second locking hole 52 and the third locking hole 222 are the same, and are all square. In this way, by inserting the locking pin 71 inside the first locking hole 42, the second locking hole 52 and the third locking hole 222, it is convenient to lock the position of the interception rack 5. Specifically, when the first locking hole 42, the second locking hole 52 and the third locking hole 222 are in the same length direction and the projections along the length direction coincide, the locking pin 71 is inserted to lock the interception rack 5 on the guide rail 22; and, if at this time the length direction of the interception rack 5 is perpendicular to the length direction of the storage rack 4 and the interception rack 5 is upward, as shown in FIG. Figure 3 and Figure 4 As shown, the locking pin 71 can also simultaneously lock the intercepting frame 5 in the second station; similarly, when the intercepting frame 5 and the storage rack 4 are in the same length direction, the first locking hole 42 and the second locking hole 52 are in the same length direction and the projections along the length direction coincide, and the locking pin 71 is inserted to lock the intercepting frame 5 in the first station.

[0067] Second embodiment

[0068] like Fig.16 and Fig.17As shown, the intelligent robot for warehousing and transportation of the second embodiment of the utility model is based on the first embodiment, with the difference that a locking mouth 223 is further provided on the guide rail 22, and the locking mouth 223 is located below the gaps of the three surrounding frames 3 and is connected to the bottom of the end of the strip mouth 221, and the locking mouth 223 is semicircular and adapted to the roller 61.

[0069] After adopting the above structure, when the roller 61 rolls to the end below the notch in the strip opening 221, the roller 61 drops into the lock opening 223, which is convenient for fixing the position of the roller 61. In this position, the position of the roller 61 is prevented from shifting, ensuring that the position of the slope end formed by the combination of the intercepting rack 5 and the storage rack 4 is fixed, which is beneficial to the stable loading and unloading of the cargo shelf, and avoids the intercepting rack 5 and the storage rack 4 from shifting in position during loading and unloading, causing the cargo shelf to fall and be damaged.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
