Description

Technical Field

[0001] The utility model relates to the technical field of logistics warehousing, in particular to a warehousing forklift and a logistics warehousing system. Background Art

[0002] Smart warehousing is a key component of the logistics process. Its application ensures the speed and accuracy of data input at every stage of warehouse management, ensuring that companies have timely and accurate access to real inventory data and can maintain and control inventory appropriately. Scientific coding also facilitates the management of inventory batches and expiration dates.

[0003] Currently, intelligent warehouse forklifts are widely used in the field of warehousing and logistics for the transportation and handling of goods. Existing intelligent warehousing is to set up multiple shelves in the warehouse, and the goods are placed on the shelves using brackets. The warehouse forklift uses two forks to lift the brackets with the goods, drive the brackets to move to the destination, and use the lifting mechanism to drive the forks to lift and place the brackets with the goods at different heights on the shelves. However, existing warehouse forklifts have the following defects: when the warehouse forklift uses the forks to carry heavier goods, the forks carrying the heavier goods extend forward, causing the center of gravity to shift forward, making the warehouse forklift at risk of overturning. Existing warehouse forklifts generally have a counterweight block at the rear of the vehicle body to solve the problem of the center of gravity shifting forward, but the installation of the counterweight block increases costs. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a warehouse forklift and a logistics warehousing system. When transporting goods on the shelves, the mobile bracket and the fork assembly for transporting the goods move forward synchronously, and the support is provided by the support wheels on the front side of the mobile bracket, thereby preventing the warehouse forklift from tipping over due to the forward shift of the center of gravity, eliminating the need to set a counterweight block, and reducing costs.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] The utility model provides a warehouse forklift, comprising a mobile base, a mobile bracket and a driving mechanism for driving the mobile bracket to move forward and backward, a support mechanism being provided on the front side of the mobile bracket, the support mechanism comprising two support modules arranged symmetrically on the left and right, the support module comprising a vertically arranged support plate and a first support wheel arranged at the bottom of the support plate, the support module being located on the front side of the mobile base, a fork assembly and a lifting mechanism for driving the fork assembly to rise and fall, being provided on the mobile bracket.

[0007] In this solution, a warehouse forklift moves to the corresponding shelf on a mobile base. The lifting mechanism drives the fork assembly up and down, and the mobile frame and fork assembly move forward and backward synchronously. When the fork assembly extends forward to pick up or place goods, the mobile frame moves forward in tandem. The support mechanism on the front of the mobile frame contacts the ground to provide support, preventing the warehouse forklift from tipping over due to the forward shift in its center of gravity and ensuring smooth cargo handling.

[0008] This solution provides support force through the contact between the support mechanism and the ground, preventing the warehouse forklift from tipping over due to the forward shift of the center of gravity. There is no need to set a counterweight block, which reduces costs. The lack of a counterweight block reduces the weight of the warehouse forklift and also reduces power consumption.

When the first drive wheel moves forward to the front extreme position, the second support wheel moves forward to a position where it is not in contact with the guide seat. That is, the second support wheel drops a certain height, and the first support wheel drops synchronously to contact the ground, providing support force. When the first drive wheel moves backward to the rear extreme position, the second support wheel moves backward to the guide seat.

[0020] Preferably, a third support bar is provided on the outside of the column, and the third support bar is inclined upward from front to back. The front end of the third support bar is connected to the second support bar on the corresponding side, and the rear end of the third support bar is connected to the column.

[0021] The third support bar is used to strengthen the column, reduce the force on the column, and prevent the column from bending and deforming due to the warehouse forklift carrying heavy goods.

There is no need to set a counterweight block, which reduces costs. The lack of a counterweight block reduces the weight of the warehouse forklift and also reduces power consumption. (2) When the mobile bracket extends forward from the mobile base, the first support wheel contacts the ground to provide support force. When the mobile bracket retracts backward to the mobile base, the first support wheel does not contact the ground and does not generate resistance, which facilitates the movement of the mobile base.

[0040] The mobile bracket 2 includes a first support bar 6 and two second support bars 7. The first support bar 6 is arranged along the left and right directions. The two second support bars 7 are symmetrically arranged at the left and right ends of the first support bar 6. The rear end of the second support bar 7 is connected to the first support bar 6. The second support bar 7 and the first support bar 6 are perpendicular to each other. The two support modules are respectively arranged on the front sides of the two second support bars 7, and the top of the support plate 3 is connected to the front end of the corresponding second support bar 7.

[0041] The driving mechanism includes a first driving wheel 8 arranged at the bottom of the first support bar 6 and a first driving motor 9 for driving the first driving wheel 8 to rotate. The first driving wheel 8 can move forward and backward along the top surface of the movable base 1. A second supporting wheel 10 is provided on the outside of the second supporting bar 7. A guide seat 39 is provided at a position corresponding to the top surface of the movable base 1 and the second supporting wheel 10. The second supporting wheel 10 is located above the corresponding guide seat 39. The guide seat 39 is a right-angled trapezoid. The guide seat 39 includes a rectangular portion 11 and a triangular portion 12. The triangular portion 12 is located in front of the rectangular portion 11. When the first driving wheel 8 moves forward to the front limit position, the second supporting wheel 10 does not contact the guide seat 39, and the first supporting wheel 4 is in contact with the ground for support. When the first driving wheel 8 moves backward to the rear limit position, the second supporting wheel 10 is located on the rectangular portion 11 and in contact with the rectangular portion 11 for support, and the first supporting wheel 4 is not in contact with the ground.

[0042] The movable base 1 includes a bottom plate 13, a base in an E shape is provided on the top of the bottom plate 13, a moving mechanism is provided at the bottom of the bottom plate 13, the base includes a connecting block 14 and three mutually parallel supporting blocks 15, the connecting block 14 is arranged along the left and right directions, the supporting block 15 is arranged in front of the connecting block 14, the supporting block 15 and the connecting block 14 are perpendicular to each other, and the supporting block 15 is arranged along the front and back directions, the fork assembly 5 includes a lifting seat 28 and two forks 29, the two forks 29 are symmetrically arranged in front of the lifting seat 28, and the space between adjacent supporting blocks 15 is used for the forks 29 to pass through, the supporting blocks 15 on the left and right sides are respectively located under the two second support bars 7, and the front ends of the supporting blocks 15 on the left and right sides are provided with notches 40 for accommodating support modules, the middle supporting block 15 is located under the first driving wheel 8, and the middle supporting block 15 is symmetrically provided with roller groups on the left and right sides, and the roller group includes a plurality of rollers 16 arranged in a straight line along the front and back directions, the rollers 16 are in contact with the middle supporting block 15, the rollers 16 are arranged horizontally, and the rollers 1 6 can roll back and forth along the middle support block 15, and the roller is rotatably connected to the bottom of the first support bar 6 16.

[0043] Two roller assemblies clamp the middle support block, acting as a limiting guide. When the first drive motor drives the first drive wheel forward, the two second support bars of the mobile bracket extend forward, driving the second support wheel and support module on the second support bar forward. The support module moves forward and out of the corresponding gap. When the first drive wheel moves forward to the front extreme position, the second support wheel moves forward to a position where it is not in contact with the guide seat. That is, the second support wheel drops a certain height, and the first support wheel simultaneously drops to contact the ground, providing support force. When the first drive wheel moves backward to the rear extreme position, the support module moves backward and retracts into the corresponding gap, and the second support wheel moves backward onto the rectangular portion of the guide seat and contacts and supports the rectangular portion. That is, the second support wheel rises a certain height, and the first support wheel simultaneously rises a certain height to not contact the ground. In this way, the first support wheel does not generate resistance when the mobile base moves. When the first drive wheel moves backward to the rear extreme position, the distance between the first support wheel and the ground is 1 to 3 cm.

[0044] A camera 17 is located in the middle of the bottom surface of the base 13. The mobile mechanism includes four universal wheels 18 and two drive modules. The four universal wheels 18 are located at the four corners of the bottom surface of the base 13. The two drive modules are symmetrically located on the front and rear sides of the bottom of the base 13. The drive modules include a second drive wheel 19 and a second drive motor for driving the second drive wheel 19. The second drive wheel is arranged to move left and right to facilitate the lateral movement of the mobile base. The camera is used to identify the movement path of the mobile base as it moves.

[0045] The lifting mechanism includes a fixed gantry 20, a lifting gantry 21, a lifting cylinder 22 and a plurality of lifting components. The fixed gantry 20 includes a column 23 symmetrically arranged on the top of the first support bar 6. The lifting gantry 21 includes a support column 24 symmetrically arranged on the left and right and a crossbeam 25 connecting the tops of the two support columns 24. The support column 24 is located on the inner side of the corresponding side column 23 and can move up and down along the corresponding side column 23. The lifting component includes a guide wheel 26 and a chain 27. The guide wheel 26 is set on the crossbeam 25. At the bottom, the front end of the chain 27 is connected to the top of the lifting seat 28, and the rear end of the chain 27 passes around the guide wheel 26 and is connected to the first support bar 6. The jacking cylinder 22 is set on the top of the first support bar 6. The jacking cylinder 22 is used to drive the lifting gantry 21 to rise and fall along the column 23. The jacking cylinder 22 is set vertically, and the telescopic end of the top of the jacking cylinder 22 is connected to the crossbeam 25. The inner side of the support column 24 is vertically provided with a guide groove 30. The lifting seat 28 is provided with a rolling wheel 31 that can roll along the guide groove 30 at a position corresponding to the guide groove 30. The jacking cylinder drives the crossbeam to rise, driving the guide wheel to rise, and the front end of the chain moves upward to drive the fork assembly to rise.

[0046] A third support bar 32 is provided on the outside of the column 23. The third support bar 32 is tilted upward from front to back. The front end of the third support bar 32 is connected to the second support bar 7 on the corresponding side, and the rear end of the third support bar 32 is connected to the column 23. The third support bar is used to strengthen the column, reduce the force on the column, and prevent the column from bending when a warehouse forklift transports heavy goods.

[0047] In this solution, a warehouse forklift moves to the corresponding shelf via a mobile base, and the lifting mechanism drives the fork assembly to rise and fall, with the mobile bracket and the fork assembly moving forward and backward synchronously. When the fork assembly extends forward to pick up or place goods, the mobile bracket moves forward synchronously, the second support wheel moves forward to a position where it does not contact the guide seat, that is, the second support wheel drops a certain height, the support module moves forward to leave the corresponding gap, and the first support wheel simultaneously drops to contact the ground, providing support force to prevent the warehouse forklift from tipping over due to the forward shift in center of gravity, ensuring smooth cargo handling. When the fork assembly retracts backward, the mobile bracket moves backward synchronously, the support module moves backward to retract the corresponding gap, and the second support wheel moves backward to the rectangular portion of the guide seat and contacts and supports the rectangular portion, that is, the second support wheel rises a certain height, and the first support wheel simultaneously rises a certain height to not contact the ground. In this way, the first support wheel does not generate resistance when the mobile base moves, facilitating the movement of the mobile base. In this embodiment, when the first drive wheel moves backward to the rear extreme position, the distance between the first support wheel and the ground is 1.5 cm.

[0048] This solution provides support through ground contact with the support mechanism, preventing the forklift from tipping over due to a forward shift in its center of gravity. This eliminates the need for a counterweight, reducing costs. The lack of a counterweight also reduces the weight of the forklift and reduces power consumption. When the mobile bracket extends forward from the mobile base, the first support wheel contacts the ground, providing support. When the mobile bracket retracts back into the mobile base, the first support wheel no longer contacts the ground, generating no resistance and facilitating movement of the mobile base.

[0049] A logistics warehousing system of this embodiment, such as Figures 7 to 11 As shown, it includes a shelf 33, a bracket 34 and the above-mentioned warehouse forklift. The shelf 33 includes a frame body, a plurality of cargo plates 35 are provided on the frame body, and a plurality of storage spaces are provided on the cargo plates 35. The bracket 34 is used to place cargo 36. The bracket 34 is square, and the bracket 34 is provided with two first through holes 37 passing through the bracket 34 side by side along the front-to-back direction. The bracket 34 is provided with two second through holes 38 passing through the bracket 34 side by side along the left-to-right direction. The first through hole 37 is connected to the second through hole 38. The two first through holes 37 and the two second through holes 38 form a well shape. The width of the bracket 34 is less than the distance between the two second support bars 7.

[0050] The first through hole and the second through hole are used for the fork to pass through. The first through hole and the second through hole have the same height and are both greater than the height of the fork, that is, the fork can move up and down in the first through hole and the second through hole.

[0051] In this solution, when the warehouse forklift transports goods, the two forks of the fork assembly are respectively inserted into the two first through holes or the two second through holes of the bracket on which the goods are placed. Since the width of the bracket is smaller than the distance between the two second support bars, after the mobile bracket moves forward, the two second support bars are located on both sides of the bracket, which will not affect the fork assembly's transportation of the bracket on which the goods are placed. In addition, when the warehouse forklift takes and places the bracket on which the goods are placed on the shelf, the two second support bars will not interfere with the bracket on the ground.

[0052] The process for a warehouse forklift to move a pallet with goods on the ground to the shelf is as follows:

[0053] like Figure 7 As shown, the warehouse forklift moves to the front side of the bracket with the goods through the mobile base; then, the first drive motor drives the first drive wheel to move forward, and the two second support bars of the mobile bracket extend forward, driving the second support wheel and the support module on the second support bar to move forward, and the support module moves forward to leave the corresponding gap. When the first drive wheel moves forward to the front limit position, as shown in FIG. Figure 8As shown, the second support wheel moves forward to a position where it does not contact the guide seat, the first support wheel contacts the ground to provide support force, the two forks are respectively inserted into the two first through holes of the bracket, and the bracket and the cargo on it are located between the two second support bars; then, as shown Figure 9 As shown, the lifting mechanism drives the fork to rise and lifts the bracket with the goods; then, the first drive motor drives the first drive wheel to move backward. When the first drive wheel moves backward to the rear limit position, the support module moves backward and retracts into the corresponding gap, and the second support wheel moves backward to the rectangular part of the guide seat and contacts and supports the rectangular part. The first support wheel rises to a certain height and does not contact the ground, as shown in FIG. Figure 10 As shown, the warehouse forklift transports the bracket with the goods to the front side of the shelf; finally, the lifting mechanism drives the fork to rise to the height of the target storage position, the first drive motor drives the first drive wheel to move forward, the two second support bars of the mobile bracket extend forward, driving the second support wheel and the support module on the second support bar to move forward, and the support module moves forward to leave the corresponding gap. When the first drive wheel moves forward to the front limit position, as shown in FIG. Figure 11 As shown, the second support wheel moves forward to a position where it does not contact the guide seat, and the first support wheel contacts the ground to provide support force. The bracket placed on the ground under the shelf and the goods on it are located between the two second support bars. The fork transports the bracket with the goods to the top of the target storage position, and the lifting mechanism drives the fork to descend and place the bracket with the goods on the target storage position, completing the loading operation.
