Description

Technical Field

[0001] The present invention relates to the technical field of transport vehicles, and in particular to a rotary electric lifting AGV transport vehicle. Background Art

[0002] Automated Guided Vehicle (AGV), as the main implementation method of automated logistics, is widely used in fields with repetitive handling, high handling intensity, harsh working environment and high environmental requirements. On the one hand, AGV can ensure operational accuracy, efficiency and safety in scenarios such as repetitive handling, high-precision stacking and high-level storage and retrieval, and maintain stable operation 24 hours a day, replacing traditional forklift operations. On the other hand, based on the scheduling system, it can be connected with automated equipment such as rollers and shuttles, or multiple vehicles can collaborate to realize unmanned operation of the entire production process and improve handling efficiency.

[0003] When barrel-shaped objects are processed or stacked, a transport vehicle is used to transport and transfer the barrel-shaped objects. Some transport vehicles are provided with arc-shaped clamping components, and the arc-shaped clamping components are used to clamp the outer wall of the barrel-shaped objects, thereby transporting and transferring the barrel-shaped objects. Since the inner arc surface diameter of the arc-shaped clamping components used to clamp the barrel-shaped objects is fixed, when the arc-shaped clamping components on the transport vehicle clamps a barrel-shaped object with a smaller diameter, the two ends of the arc-shaped clamping components will not be able to press against the surface of the barrel-shaped object, and the parts from the two ends of the arc-shaped clamping components to the middle end will not be able to fit closely to the surface of the barrel-shaped object as the diameter of the barrel-shaped object decreases, thereby reducing the clamping strength of the arc-shaped clamping components on the barrel-shaped object.

[0034] The following will refer to the attached Figures 1 to 8 The embodiments of the present invention are described in detail. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0035] A rotary electric lifting AGV transporter, as shown in the attached Figure 1-Figure 8 As shown, including:

[0036] A transport vehicle 10 is provided with a mounting frame 11, and two clamping units 12 are provided on the mounting frame 11, and the two clamping units 12 are arc-shaped and used to clamp the oil drum, so as to facilitate the transfer of the oil drum. The clamping unit 12 comprises an arc-shaped shell, and the inner concave surface of the arc-shaped shell has a receiving cavity, and the interior of the arc-shaped shell is provided with a first clamping member 120 and a plurality of second clamping members 121, and the inner wall of the first clamping member 120 is fixed inside the arc-shaped shell, and the outer wall of the second clamping member 121 is movably connected inside the arc-shaped shell, and the plurality of second clamping members 121 are four, and the four second clamping members 121 are grouped in pairs, and the two groups of second clamping members 121 are symmetrical with the first clamping member 120 as the center, and the second clamping member 121 cooperates with the first clamping member 120 to clamp the oil drum, so as to maintain the stability of the oil drum during transfer;

[0037] The first clamping member 120 comprises a first square frame 1201 and a second square frame 1202, and the maximum width of the second square frame 1202 is smaller than the minimum width of the first square frame 1201, and the outer wall of the second square frame 1202 is slidably connected to the inner wall of the first square frame 1201, and a first reset spring 1203 is fixed between the outer wall of the second square frame 1202 and the inner wall of the first square frame 1201, for supporting the second square frame 1202, so as to facilitate the reset of the second square frame 1202, and a first clamping block 1204 is fixed to the inner wall of the second square frame 1202, for clamping the oil drum, so as to limit the oil drum.

[0038] The second clamping member 121 includes a third square frame 1211 and a fourth square frame 1212, and the maximum width value of the fourth square frame 1212 is smaller than the minimum width value of the third square frame 1211, and the outer wall of the fourth square frame 1212 is slidably connected to the inner wall of the third square frame 1211, and a second reset spring 1213 is fixed between the outer wall of the fourth square frame 1212 and the inner wall of the third square frame 1211, which is used to support the fourth square frame 1212, so as to facilitate the reset of the fourth square frame 1212, and a second clamping block 1214 is fixed to the inner wall of the fourth square frame 1212, which is used to clamp the oil barrel, thereby limiting the oil barrel.

[0039] Since the two clamping units 12 can approach and move away from each other, and the two groups of second clamping members 121 can also approach and move away from each other, and the sliding trajectory of the two groups of second clamping members 121 approaching and moving away from each other is arc-shaped, by controlling the control box installed on the transport vehicle 10, the clamping unit 12 is first driven to move down in height, and then the two clamping units 12 are driven to approach each other, so that the first clamping member 120 and the second clamping member 121 are against the surface of the oil drum. Since the first clamping member 120 and the second clamping member 121 are arc-shaped, and the arc-shaped surface of the oil drum fits the clamping surfaces of the first clamping member 120 and the second clamping member 121, at this time, the first clamping block 1204 will drive the second square frame 1202 to slide into the inside of the first square frame 1201, so that the second square frame 1202 compresses the first reset spring 1203, and at the same time, the second clamping block 1214 will drive the fourth square frame 1212 to slide into the inside of the third square frame 1211, so that the fourth square frame 1212 The second return spring 1213 is compressed, and the first return spring 1203 and the second return spring 1213 respectively drive the first clamping block 1204 and the second clamping block 1214 connected thereto to be close to the surface of the oil barrel, thereby maintaining the clamping strength of the oil barrel. When the two clamping units 12 approach each other to clamp the oil barrel with a smaller diameter, the first clamping block 1204 will first be against the surface of the oil barrel, and the first clamping block 1204 drives the second square frame 1202 to slide toward the first square frame 12 01, at this time, the two groups of second clamping members 121 will slide toward the oil drum in an arc trajectory, and the sliding angle of the second clamping member 121 located at the tail end of the arc shell is greater than the sliding angle of the second clamping member 121 close to the first clamping member 120, so that the first clamping member 120 and the second clamping member 121 can be against the surface of the oil drum to clamp and limit it. After the first clamping member 120 and the second clamping member 121 clamp the oil drum, the oil drum is transferred by the transport vehicle 10 for subsequent processing.

[0040] refer to Figure 1-Figure 8As shown, a first driving assembly 20 is mounted on the arc-shaped shell for driving the second clamping member 121 to rotate, so as to clamp oil drums of different diameters for transfer and subsequent processing.

[0041] The first driving assembly 20 includes a top plate 21 installed on the top of the third-party frame 1211, and a linkage shaft 22 is fixed on the top of the top plate 21. The linkage shaft 22 cooperates with the top plate 21 to drive the third-party frame 1211 to slide, so that the second clamping block 1214 is clamped on the surface of the oil drum to clamp and limit the oil drum. A first linkage groove is provided on the top of the arc shell, and the linkage shaft 22 is slidably connected to the inside of the first linkage groove, and the first linkage groove is arc-shaped, which is used to limit the linkage shaft 22, so as to facilitate the arc-shaped sliding of the linkage shaft 22. A second linkage groove is provided on the inner bottom wall of the arc shell, and the second linkage groove is arc-shaped. A limiting shaft is fixed to the bottom of the third-party frame 1211, and the limiting shaft is slidably connected to the inside of the second linkage groove.

[0042] An arc-shaped driving plate 23 is fixed to the outer surface of the linkage shaft 22, which is used to drive the top plate 21 to slide through the linkage shaft 22, thereby driving the second clamping block 1214 to clamp and limit the oil drum. A limited circular hole is opened on the top of the arc shell, and the inner wall of the limited circular hole is rotatably connected with a rotating shaft 24. The rotating shaft 24 consists of an upper rotating shaft and a lower rotating shaft. The bottom of the upper rotating shaft is rotatably connected to the top of the lower rotating shaft, and the maximum diameter value of the rotating shaft 24 is smaller than the minimum diameter value of the limiting circular hole, and the bottom of the lower rotating shaft is rotatably connected to the top of the first square frame 1201, and the arc-shaped driving plate 23 is fixed on the outer wall of the rotating shaft 24 toward the side of the rotating shaft 24. The rotating shaft 24 can adjust the angle of the third square frame 1211 connected to it through the arc-shaped driving plate 23, so as to facilitate the second clamping block 1214 to clamp oil drums of different diameters.

[0043] Two gear sets are installed on the outer surface of the rotating shaft 24, and the two gear sets are installed on the upper rotating shaft and the lower rotating shaft respectively, and the gear set includes a first gear 25 and a second gear 26, and the two first gears 25 and the second gears 26 are alternately arranged on the outer surface of the rotating shaft 24, and the top of the arc-shaped shell is slidably connected to two sliding plates 27, and the two sliding plates 27 are symmetrical with the rotating shaft 24 as the center, and the two sliding plates 27 are arranged up and down, and the two sliding plates 27 correspond to the two gear sets, and a support arm 210 is fixed between the two sliding plates 27 for supporting the sliding plate 27, so as to maintain the stability of the sliding plate 27, and the arc-shaped shell A first slide groove is opened at the top, and a second slide groove is opened at the top of the second square frame 1202. The interior of the second slide groove is slidably connected to a limit plate, and the limit plate slides inside the first slide groove, and the top of the limit plate is fixed to the bottom of the support arm 210, and the bottom of the limit plate is fixed to the top of the second square frame 1202. A first rack 28 and a second rack 29 are fixed to the side of the sliding plate 27 facing the rotating shaft 24, and the first rack 28 is threadedly connected to the first gear 25, and the second rack 29 is threadedly connected to the second gear 26. The top of the arc shell is fixed with an outer shell 211, and the top of the upper rotating shaft is rotatably connected to the inner top wall of the outer shell 211.

[0044] Since the number of teeth of the first gear 25 is greater than the number of teeth of the second gear 26, and when the first gear 25 and the second gear 26 rotate at the same time, the size of the rotation angle is also different, and the rotation angle of the second gear 26 is greater than the rotation angle of the first gear 25, when the clamping unit 12 clamps the oil drum with a smaller diameter, the first clamping block 1204 first abuts against the surface of the oil drum, and as the two clamping units 12 approach each other, the first clamping block 1204 drives the second square frame 1202 to slide toward the first square frame 1201, and the second square frame 1202 drives the sliding plate 27 to slide toward the arc shell through the limit plate and the support arm 210. At the inner wall of the lower rotating column, the first rack 28 corresponding to the lower rotating column drives the first gear 25 on the lower rotating column to rotate, and the second rack 29 corresponding to the lower rotating column drives the second gear 26 on the lower rotating column to rotate. At this time, the first gear 25 and the second gear 26 on the lower rotating column rotate in the same direction, and the two third rectangular frames 1211 corresponding to the lower rotating column rotate to the oil barrel, and the limiting shaft slides from the head end of the corresponding second linkage slide to its tail end, and the linkage shaft 22 slides from the head end of the corresponding first linkage slide to its tail end, and the second clamping block 1214 clamps the oil barrel.

[0045] The first rack 28 corresponding to the upper rotating column drives the first gear 25 on the upper rotating column to rotate, and the second rack 29 corresponding to the upper rotating column drives the second gear 26 on the upper rotating column to rotate. At this time, the first gear 25 and the second gear 26 on the upper rotating column rotate in the same direction, and the rotation direction of the upper rotating column is opposite to the rotation direction of the lower rotating column. The two third rectangular frames 1211 corresponding to the upper rotating column rotate to the oil barrel, and the limiting shaft slides from the head end of the corresponding second linkage slide groove to its tail end, and the linkage shaft 22 slides from the head end of the corresponding first linkage slide groove to its tail end, and the second clamping block 1214 clamps the oil barrel, so that the second clamping member 121 can evenly clamp oil barrels of different diameters, and keep multiple second clamping members 121 able to clamp the oil barrel.

[0046] refer to Figure 3 , Figure 5 and Figure 7 As shown, a clamping assembly 30 is disposed inside the arc-shaped shell for pushing the second clamping block 1214 to tightly press against the surface of the oil drum to clamp it, thereby maintaining the stability of the transport vehicle 10 when transferring the oil drum.

[0047] The clamping assembly 30 includes two square blocks 31 fixed at the bottom of the top plate 21, and the two square blocks 31 are symmetrical with the linkage shaft 22 as the center. The top of the arc shell is slidably connected with a plurality of sliding grooves 32, and the number of the sliding grooves 32 is the same as the number of the square blocks 31. The square blocks 31 are slidably connected inside the sliding grooves 32 to limit the square blocks 31 so as to maintain the stability of the square blocks 31 when sliding. A third reset spring 34 is fixed between one side of the square block 31 and the inner wall of the sliding groove 32 to support the square block 31 so as to facilitate the reset of the square block 31.

[0048] Two groups of arc-shaped parts 36 are fixed to the inner wall of the arc-shaped shell, and the two groups of arc-shaped parts 36 are symmetrical with the first clamping part 120 as the center, and the arc-shaped part 36 is composed of a first arc-shaped plate and a second arc-shaped plate, the first arc-shaped plate corresponds to the second clamping part 121 close to the first clamping part 120, and the second arc-shaped plate corresponds to the second clamping part 121 far away from the first clamping part 120, the first arc-shaped plate and the second arc-shaped plate both have guide surfaces, and the head end of the guide surface is far away from the cavity opening of the arc-shaped shell, and the tail end of the guide surface is close to the cavity opening of the arc-shaped shell, and a linkage arc block 35 is fixed on the side of the second clamping part 121 facing the inner wall of the arc-shaped shell, and the output end position of the linkage arc block 35 is located at the head end of the arc-shaped part 36.

[0049] Since the length of the second arc plate is greater than that of the first arc plate, when the rotating shaft 24 drives the top plate 21 to slide through the linkage shaft 22 and the arc driving plate 23, the top plate 21 drives the third square frame 1211 to slide toward the middle of the clamping unit 12 through the square block 31 and the third return spring 34. At this time, the linkage arc block 35 slides from the head end of the arc member 36 to its tail end. At this time, the third square frame 1211 drives the fourth square frame 1212 to slide toward the middle of the clamping unit 12 through the second return spring 1213, thereby improving the clamping strength of the second clamping block 1214 on the oil drum and maintaining the stability of the transport vehicle 10 when transferring the oil drum.

[0050] refer to Figure 1 and Figure 2 As shown, a second driving assembly 40 is installed on the mounting frame 11, which is used to drive the clamping unit 12 to clamp and limit the oil barrel, thereby facilitating the transfer of the oil barrel and subsequent processing.

[0051] The second driving assembly 40 includes a recessed frame 41 slidably connected to a side wall of the mounting frame 11, and the recess of the recessed frame 41 faces the clamping unit 12, and the inner wall of the recessed frame 41 is rotatably connected with a reciprocating screw 42, and the two clamping units 12 are fixed with a limiting slider 43 on one side facing the recessed frame 41, and the limiting slider 43 is slidably connected to the reciprocating screw 42, and the reciprocating screw 42 can drive the two clamping units 12 to approach and move away from each other through the limiting slider 43, thereby facilitating the two clamping units 12 to clamp and limit the oil drum.

[0052] A driving motor 44 is installed on one side wall of the concave frame 41, and the output end of the driving motor 44 is fixed to one end of the reciprocating screw 42, so as to drive the reciprocating screw 42 to rotate around its axial direction, thereby adjusting the position of the two clamping units 12. A lifting block 45 is fixed on the side of the concave frame 41 away from the clamping unit 12, and the lifting block 45 is slidably connected to the inner wall of the mounting frame 11, so as to support the concave frame 41, so as to facilitate driving the concave frame 41 to slide up and down to adjust the height.
