Description

Technical Field

[0001] The utility model relates to a moving chassis and a transport device, belonging to the technical field of intelligent warehousing. Background Art

[0002] With the rapid development of the logistics and warehousing industry, the construction of high-rise warehouses for cargo storage is becoming more and more widespread. There are more and more intelligent devices such as stacking AGVs and AMRs used in high-rise warehouses, especially fork-type intelligent devices. The goods are stacked on pallets, and the pallets are picked up by forks to achieve the transfer of goods.

[0003] In order to adapt to the ground, the chassis assembly of the existing robot includes two hinged chassis; a driving wheel assembly arranged on one of the chassis, and a universal wheel assembly connected to each chassis through a buffer assembly; the support platform is respectively connected to the two chassis through an adjustment assembly. When the above structure is adopted, the universal wheel assembly is connected to the chassis by using a buffer assembly, so that the robot chassis can have a certain degree of adaptability to the ground, thereby ensuring the contact between each universal wheel assembly and the ground, and enhancing the stability of the chassis.

[0004] However, it also has the following disadvantages: in order to prevent the driving wheel from slipping, the support platform is arranged directly above the driving wheel assembly. This arrangement causes universal wheel assemblies to be arranged on both sides of the driving wheel assembly, which makes the structure of the chassis more complicated. Utility Model Content

[0063] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0064] This embodiment provides a moving chassis and a transport device that are simple in structure and can prevent slipping.

[0065] Figure 1 This is a schematic diagram of the main structure of the transport device in this embodiment; Figure 2 It is a schematic diagram of the three-dimensional structure of the moving chassis in one direction in this embodiment; Figure 3 It is a schematic diagram of the three-dimensional structure of the moving chassis in another direction in this embodiment.

[0066] See also Figures 1 to 3The embodiment of the utility model provides a transport device 100, which includes a moving chassis 100a for driving a carrier to move, and the moving chassis 100a includes a bearing body 10 and a moving mechanism 20. The bearing body 10 extends on a plane defined by a first direction and a second direction perpendicular to each other, and has an installation area 101 for mounting the carrier. The installation area 101 is eccentrically arranged relative to the center line of the bearing body 10 in the first direction, and is relatively close to the first end of the bearing body 10 in the first direction. The moving mechanism 20 includes a driving wheel 21 and a driven wheel 22. The driving wheel 21 is rotatably arranged on the bearing body 10 and is relatively close to the first end of the bearing body 10 in the first direction, and part or all of the driving wheel 21 protrudes from the lower surface of the bearing body 10. The driven wheel 22 is arranged on the bearing body 10 and is relatively close to the second end of the bearing body 10 in the first direction, and part or all of the driven wheel 22 protrudes from the lower surface of the bearing body 10.

[0067] It can be understood that since the installation area 101 is eccentrically arranged and relatively close to the first end of the load-bearing body 10 in the first direction, that is, the installation area 101 is relatively close to the end where the driving wheel 21 is located, the center of gravity line of the vehicle after installation is close to the driving wheel 21, and most of the wheel pressure of the entire vehicle is on the driving wheel 21, which improves the grip between the driving wheel 21 and the ground, and is not easy to slip when walking; when the whole vehicle is traveling in a straight line, the driven wheel may be slightly deflected due to the influence of the ground working conditions, thereby dragging the driving wheel 21 to slide slightly, affecting the straight-line accuracy of the whole vehicle, which manifests as serpentine walking. The greater the grip of the driving wheel 21, the less likely this situation is to occur; when the whole vehicle is changing direction, especially when the front drive is changed to the rear drive, due to the swing of the driven wheel 22, the whole vehicle needs to correct the direction. The greater the driving wheel pressure, the greater the correction acceleration, and the easier the correction; at the same time, it is only necessary to set the driven wheel 22 on one side of the driving wheel 21. Compared with the prior art, the structure is simpler.

[0068] It should be noted that Figure 2 The direction indicated by A is the first direction. Figure 2 The direction indicated by B is the second direction.

[0069] In this embodiment, a plurality of connection holes 211 are provided at the installation area 101 of the carrier body 10 , so that the carrier body 10 is connected to the carrier by bolts.

[0070] Figure 4 This is a schematic diagram of the motion trajectory of the moving chassis turning in situ in this embodiment; Figure 5 Schematic diagram of the motion trajectory of the arc turning of the moving chassis in this embodiment.

[0071] Combination Figures 2 to 5As shown, the driving wheels 21 include two groups spaced apart along the second direction. When the two groups of driving wheels 21 rotate in opposite directions but at the same speed, the moving chassis 100a turns in situ, and the rotation center is located between the two groups of driving wheels 21.

[0072] In this embodiment, there are two driving wheels 21 and two driven wheels 22, which are spaced apart along the second direction. Each driving wheel 21 is connected to a driving motor and a servo controller, and the driven wheel 22 is a universal wheel.

[0073] It should be noted that when the motion chassis 100a moves, the control system sends instructions to the servo controller, and the servo controller controls the operation of the two drive motors, thereby driving the two drive wheels 21 to move. When the two drive wheels 21 rotate in the same direction and at the same speed, the whole vehicle can move forward or backward; when the two drive wheels 21 rotate in opposite directions and at the same speed, the whole vehicle can turn in place; when the two drive wheels 21 rotate in the same direction and at different speeds, the whole vehicle can turn in an arc; when the two drive wheels 21 rotate in opposite directions and at different speeds, the whole vehicle can turn in a near-circular arc. When the motion chassis 100a is in operation, different operating modes can be executed according to working conditions and scene requirements to improve efficiency.

[0074] Figure 6 Schematic diagram of the installation structure of the counterweight in this embodiment.

[0075] Combination Figure 6 As shown, balancing weight bins 11 are symmetrically arranged at both ends of the carrying body 10 in the second direction. The balancing weight bins 11 are relatively close to the second end of the carrying body 10 in the first direction. The balancing weight bins 11 are configured to carry the balancing weight 30 .

[0076] It can be understood that since the center of gravity of the carrier after installation is close to the driving wheel 21, that is, close to the first end of the load-bearing body 10 located in the first direction, the balancing weight bin 11 is relatively close to the second end of the load-bearing body 10 located in the first direction, the balancing weight 30 in the balancing weight bin 11 can balance the gravity exerted by the carrier on the load-bearing body 10, thereby effectively preventing the load-bearing body 10 from tipping over and ensuring the stability of the load-bearing body 10 supporting the carrier.

[0077] Combination Figure 6 As shown, the balancing weight 30 includes a plurality of balancing plates 31 , and the plurality of balancing plates 31 are stacked in the balancing weight chamber 11 along a first direction.

[0078] It can be understood that since the installation area 101 and the balancing weight chamber 11 are spaced apart relative to the first direction, the multiple balancing plates 31 stacked along the first direction in the balancing weight chamber 11 can better balance the gravity exerted by the carrier on the carrying body 10, further ensuring the stability of the carrying body 10 in supporting the carrier.

[0079] In this embodiment, chamfers are designed around the balancing piece 31 to avoid weld protrusions at the corners of various installation areas 101 .

[0080] Combination Figure 6 As shown, a stopper bar 111 and a bolt fastener 112 are also provided in the balancing weight bin 11. The stopper bar 111 is fixed to the outer side of the bottom of the balancing weight bin 11 and extends along the first direction. A notch portion 311 is provided on the outer side of the bottom end of each balancing sheet 31, and the notch portion 311 on each balancing sheet 31 abuts against the stopper bar 111. The bolt fastener 112 is configured to pass through each balancing sheet 31 along the second direction and connect to the load-bearing body 10.

[0081] It can be understood that each balancing plate 31 can be positioned in the balancing weight bin 11 through the abutment between the baffle 111 and the notch portion 311 of each balancing plate 31, and each balancing plate 31 can be fixed to the supporting body 10 through the bolt fasteners 112, thereby achieving fixed installation of each balancing plate 31 in the balancing weight bin 11, and convenient installation and disassembly, so as to increase or decrease the number of balancing plates 31 according to the expansion requirements of vehicle models.

[0082] Combination Figure 3 As shown, a receiving bin 12 is provided on the carrier body 10, and the number of the receiving bins 12 is consistent with the number of the driven wheels 22. The receiving bin 12 is relatively close to the second end of the carrier body 10 in the first direction, and the driven wheel 22 is installed in the receiving bin 12. The top of the receiving bin 12 has a first opening for the corresponding driven wheel 22 to be loaded into the receiving bin 12, and the bottom of the receiving bin 12 has a second opening for the corresponding driven wheel 22 to protrude from the lower surface of the carrier body 10. A connecting plate 221 that abuts against the upper surface of the carrier body 10 is fixed to the top of the driven wheel 22, and the connecting plate 221 is fixedly connected to the carrier body 10.

[0083] It can be understood that the driven wheel 22 can be loaded into the accommodating bin 12 from the first opening of the accommodating bin 12. When loading, the abutment between the connecting plate 221 and the supporting body 10 can limit the loading depth, and can be accurately loaded to the specified depth position. After loading, the driven wheel 22 is installed in the accommodating bin 12 through the fixed connection between the connecting plate 221 and the supporting body 10. In this way, the driven wheel 22 can be installed from top to bottom in the accommodating bin 12, and the assembly processability is good, avoiding the problems of crane frame and difficulty in hole alignment when installing from bottom to top, and the installation efficiency is effectively improved.

[0084] In this embodiment, the connecting plate 221 is covered on the upper surface of the carrying body 10 and connected to the carrying body 10 by bolts.

[0085] Combination Figure 2As shown, the moving chassis 100a further includes a guide unit 40, which is disposed at both ends of the carrying body 10 in the second direction. The guide unit 40 includes at least one guide wheel 41, which is rotatably disposed on the carrying body 10, and part or all of the guide wheel 41 protrudes from the side surface of the carrying body 10 in the second direction. The rotation plane of the guide wheel 41 is parallel to the plane defined by the first direction and the second direction.

[0086] It can be understood that when the lane is too narrow, the guide wheel 41 cooperates with the lane guide rail, and the guide wheel 41 moves in the guide rail, so that the moving chassis 100a can be suitable for the working environment of moving in a narrow lane.

[0087] In this embodiment, the number of the guide wheels 41 is four, and they are arranged in groups of two at both ends of the carrying body 10 in the second direction.

[0088] Figure 7 It is a schematic diagram of the three-dimensional structure of the bearing body in this embodiment.

[0089] Combination Figure 7 As shown, the load-bearing body 10 includes a bottom plate 13, at least two main side beams 14, and at least two auxiliary side beams 15. At least two main side beams 14 are fixed to the upper surface of the bottom plate 13 and are spaced apart along the second direction, and the main side beams 14 extend along the first direction. At least two auxiliary side beams 15 are fixed to the upper surface of the bottom plate 13 and are spaced apart along the first direction, and the main side beams 14 extend along the second direction. Each auxiliary side beam 15 is fixedly connected to all the main side beams 14.

[0090] It can be understood that the main side beam 14 , the auxiliary side beam 15 and the bottom plate 13 form a box-like structure, which has a greater reinforcing effect on the bearing capacity of the bearing body 10 , thereby enabling the bearing body 10 to have a greater bearing capacity.

[0091] In this embodiment, the main side beam 14 and the bottom plate 13 form two "I"-shaped structures on both sides of the load-bearing body 10 in the second direction, which play a strong longitudinal bearing role. The "I"-shaped structure is connected to the driving wheel 21 in front and the driven wheel 22 in the rear.

[0092] Combination Figure 7As shown, the load-bearing body 10 further includes at least one first reinforcing beam 16 and at least one second reinforcing beam 17. At least one first reinforcing beam 16 is fixed to the upper surface of the bottom plate 13 and is located between the two outermost auxiliary side beams 15. The first reinforcing beam 16 extends along the second direction, and each first reinforcing beam 16 is fixedly connected to all the main side beams 14. At least one second reinforcing beam 17 is fixed to the upper surface of the bottom plate 13 and is located between the two outermost main side beams 14. The second reinforcing beam 17 extends along the first direction, and each second reinforcing beam 17 is fixedly connected to all the auxiliary side beams 15. Each first reinforcing beam 16 is fixedly connected to all the second reinforcing beams 17.

[0093] It can be understood that the first reinforcing beam 16 , the second reinforcing beam 17 , the main side beam 14 and the auxiliary side beam 15 divide the load-bearing body 10 into a plurality of areas, further forming a box-shaped structure, thereby further enhancing the load-bearing capacity of the load-bearing body 10 .

[0094] In this embodiment, the first reinforcing beam 16 is connected to two “I”-shaped structures to play a role in lateral bearing.

[0095] Combination Figure 1 to Figure 2 As shown, the transport device 100 further includes a gantry system 100 b , which is installed in the installation area 101 . With respect to the first direction, the proximal side where the installation area 101 is located is the front side of the transport device 100 .

[0096] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0097] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
