[0027] 1. This utility model uses a walking component to enable the entire trolley to move automatically, a lifting component to carry the tilting drive mechanism and the material box to achieve the lifting function, and the material box to load the materials that need to be moved; the lifting mechanism provides power for the lifting component to move, driving the lifting component to descend from a high position to a low position, or rise from a low position to a high position; while the tilting drive mechanism drives the material box to rotate at a certain angle, which has the ability to tilt the materials; the tilting trolley can adjust the speed of automatic lifting and tilting, and requires little manual labor, which can meet the requirements of various industrial cycle times.

[0028] 2. By setting a groove on the walking base frame, when the lifting frame is lowered into place, a part of the bottom of the lifting frame is in the groove, which restricts the movement of the lifting frame in the left, right and forward and backward directions. This allows the lifting frame and its load-bearing related mechanisms to be stably placed on the walking base frame, ensuring the stability and accuracy of the lifting frame's lifting and lowering, and also enhancing the stability of the lifting and lowering process and subsequent material unloading.

[0029] 3. Through the setting of the locking mechanism, when the lifting frame descends to the position of the traveling bottom frame, the locking block is rotated around the locking shaft by the locking drive, so that the locking block and the traveling bottom frame come into contact. The force applied by the locking block towards the traveling bottom frame increases the contact force between the two, thereby generating the corresponding locking ability. In conjunction with the use of the above-mentioned insertion groove, the stability of the position of the lifting frame after it descends to the position can be better enhanced, thereby enhancing the stability of the lifting and subsequent material unloading process.

[0042] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0043] Please see Figure 1-10 As shown, a lifting and tilting material unloading trolley is used for workstation switching on a low-level production line, as well as for material transfer and tilting between high-level and low-level production lines to meet the operational needs of high and low-level materials. Specifically, it includes a walking component 1, a lifting component 2, a material box 3, and a tilting drive mechanism 4. The walking component 1 enables the entire trolley to move. The lifting component 2 carries the tilting drive mechanism 4 and the material box 3 to achieve the lifting function. The material box 3 is used to load the materials that need to be moved. The tilting drive mechanism 4 drives the material box 3 to tilt at a certain angle, thus enabling the tilting of materials.

[0044] The walking component 1 includes a horizontally arranged walking base frame 5 and a vertically fixed walking frame 6 on the walking base frame 5. A walking mechanism 7 is provided below the walking base frame 5. The walking base frame 5 and the walking frame 6 constitute the moving frame of the entire trolley. The walking mechanism 7 enables the trolley to move.

[0045] The vertical frame 6 is equipped with a lifting mechanism 8 that drives the lifting component 2 to rise and fall. The lifting mechanism 8 is used to provide power for the lifting component 2 to rise and fall, driving the lifting component 2 to descend from a high position to a low position, or rise from a low position to a high position.

[0046] The lifting assembly 2 includes a lifting frame 9, and a tilting drive mechanism 4 is mounted on the lifting frame 9. The tilting drive mechanism 4 drives the material box 3 to tilt. The lifting frame 9 serves as the entire carrier of the lifting assembly 2, and is used to transmit the lifting of the lifting mechanism 8 and to support the tilting drive mechanism 4 and the material box 3.

[0047] The traveling frame is provided with an insertion groove 10 for the bottom of the lifting frame 9 to be placed. That is, an open groove is formed at the middle of the upper part of the traveling base frame 5. When the lifting frame 9 is lowered into place, a part of the bottom of the lifting frame 9 is in the insertion groove 10, which restricts the movement of the lifting frame 9 in the left, right and forward and backward directions. This allows the lifting frame 9 and its load-related mechanisms to be stably placed on the traveling base frame 5, ensuring the stability and accuracy of the lifting of the lifting frame 9, and also enhancing the stability of the subsequent material unloading process.

[0048] A locking mechanism is provided at the bottom of the lifting frame 9 to cooperate with the traveling frame 5. The locking mechanism includes a locking shaft 11, a locking drive 12, and a locking block 13. The two ends of the locking shaft 11 are rotatably set at the bottom of the lifting frame 9 through axle seats. The locking drive 12 is mounted on the lifting frame 9. The locking block 13 is fixedly mounted on the locking shaft 11 and rotates together with the locking shaft 11. The driving end of the locking drive 12 is movably connected to the locking block 13. The locking drive 12 drives the locking block 13 to rotate around the locking shaft 11, so that the locking block 13 contacts the traveling frame to lock, or separates to release the lock. By employing a locking mechanism, when the lifting frame 9 descends to the position of the traveling base frame 5, the locking drive 12 causes the locking block 13 to rotate around the locking shaft 11 at a certain angle, bringing the locking block 13 into contact with the traveling base frame 5. The force applied by the locking block 13 towards the traveling base frame 5 increases the contact force between the two, thereby generating a corresponding locking capability. This, combined with the aforementioned insertion slot 10, further enhances the stability of the lifting frame 9 after it has descended to the correct position. When the lifting frame 9 rises, the locking block 13 rotates and does not contact the traveling base frame 5.

[0049] In one embodiment, the locking drive 12 can be a telescopic actuator such as a hydraulic cylinder or a pneumatic cylinder to drive the locking block 13 to rotate around the locking shaft 11. Alternatively, a push block 14 can be fixedly mounted on the locking shaft 11, with the locking drive 12 movably connected to the push block 14, which can also drive the rotation of the locking shaft 11 and the locking block 13. Furthermore, to further enhance the connection between the locking block 13 and the traveling frame 5, a locking groove adapted to the locking block 13 can be formed on the traveling frame 5 for insertion of the locking block 13.

[0050] In one embodiment, the lifting mechanism 8 includes a top transmission device 15, a lifting motor 16, a lifting chain 17, a counterweight assembly 18, and a lifting guide assembly 19. The top transmission device 15 is used to transmit the power of the lifting motor 16 to the lifting chain 17 as a vertical lifting force. The top transmission device 15 is mounted on the top of the traveling vertical frame 6. The top transmission device 15 includes a top transmission shaft rotatably mounted on the top of the traveling vertical frame 6. Lifting sprockets are respectively mounted at both ends of the top transmission shaft. The lifting motor 16 is connected to the transmission shaft of the top transmission device 15 through a reducer. When the lifting motor 16 is working, it transmits power to the top transmission shaft through the reducer, and the top transmission shaft can drive the lifting sprockets to rotate.

[0051] The lifting chain is connected to the lifting sprocket in the top transmission device 15. Through the meshing transmission between the lifting chain and the lifting sprocket, the lifting chain can move when the lifting sprocket rotates. One end of the lifting chain is connected to the counterweight assembly 18, and the other end is connected to the lifting frame 9 through the lifting guide assembly 19. The counterweight assembly 18 and the lifting guide assembly 19 form an up-down or down-up operating mode. The counterweight assembly 18 can reduce the workload of the lifting motor 16.

[0052] The lifting guide assembly 19 includes a lifting guide column and a lifting guide block 20. The lifting guide column is vertically fixed on the traveling base frame 5. This lifting guide column can be used in conjunction with the traveling vertical frame 6; that is, the traveling vertical frame 6 can be used as a lifting guide column, and the lifting guide column can also be fixedly mounted on the traveling vertical frame 6. The lifting guide block 20 is connected to the lifting frame 9. The lifting frame 9 can achieve lifting and lowering movements through the lifting and lowering of the lifting guide block 20. The lifting guide block 20 is slidably mounted on the lifting guide column. Four guide wheel sets 21 are arranged between the lifting guide column and the lifting guide block 20, with each set positioned in pairs on either side of the lifting guide column, providing stable guidance for the lifting and lowering movement of the lifting guide block 20.

[0053] Mounting blocks 22, perpendicular to the lifting guide block 20, are fixedly installed on both sides of the lifting guide block 20. A guide wheel assembly 21 is installed at the upper and lower ends of each mounting block 22. A connecting block 23 is installed on the inner top of the lifting guide block 20 via bolts, allowing for vertical adjustment. A first adjusting block 24 is fixed to the outer upper part of the connecting block 23, and a second adjusting block 25 is fixed to the outer top of the lifting guide block 20. The first adjusting block 24 and the second adjusting block 25 are connected by adjusting bolts 26. The top of the connecting block 23 is a hinged end that hinges to the lifting chain. The vertical adjustment of the connecting block 23 and the lifting guide block 20, along with the adjustable installation between the outer side of the connecting block 23 and the lifting guide block 20, allows the connecting block 23 to have vertical adjustment capabilities. This enables fine-tuning of the vertical position of the lifting guide block 20, further improving the accuracy of the lifting assembly 2 and enhancing the connection strength between the connecting block 23 and the lifting guide block 20.

[0054] The lifting frame 9 includes an upper lifting base frame 27, a lower lifting base frame 28, and lifting side frames 29. The upper lifting base frame 27 is horizontally fixed on one side above the lower lifting base frame 28, and a space is left on the other side above the lower lifting base frame 28 for the installation of the tilting drive mechanism 4. The lifting side frames 29 are fixedly installed on both sides of the lower lifting base frame 28. The upper and lower heights of the lifting side frames 29 are respectively fixedly provided with mounting connecting plates 30 extending outwards. The two mounting connecting plates 30 are fixedly connected to the lifting guide block 20 by bolts. Adjustment holes are arranged between the mounting connecting plates 30 and the lifting guide block 20 so that the two can be adjusted at a certain distance in the horizontal direction, so that the lifting guide block 20 has the ability to make fine adjustments relative to the lifting guide column.

[0055] Inclined brackets 31 are fixedly installed on both sides of the lifting side frame 29 and the lifting lower base frame 28. The connection position of the inclined brackets 31 with the lifting side frame 29 is higher than half the height of the lifting side frame 29, so that it has stable support. The outer circumferential dimensions of the lifting lower base frame 28 are adapted to the insertion groove 10. The depth of the insertion groove 10 is not greater than the height of the lifting lower base frame 28, so that the lifting lower base frame 28 can be smoothly connected to the insertion groove 10, and also avoid the lifting lower base frame 28 being too deep in the insertion groove 10, which would affect the convenience of the lifting lower base frame 28 rising. A stop block 32 is fixedly installed at the upper end of the outer circumference of the lifting lower base frame 28. When the lifting lower base frame 28 is lowered into place, the stop block 32 abuts against the traveling base frame 5 to mechanically limit the depth of the lifting lower base frame 28 entering the insertion groove 10.

[0056] The upper lifting frame 27 is equipped with a conveyor roller conveyor 33, that is, a row of conveyor rollers is installed on the upper lifting frame 27, and the conveyor rollers are connected by transmission. The conveyor rollers are driven by a motor installed on the upper lifting frame 27, and the material box 3 is automatically moved back and forth on the conveyor through the conveying pipe.

[0057] The tilting drive mechanism 4 is located on one side of the upper lifting frame 27. The tilting drive mechanism 4 includes a rotating frame 34, a rotating drive device 35, and a tilting rotating shaft 36. The tilting rotating shaft 36 is mounted on the upper lifting frame 28 via a rotating shaft seat 37 mounted on the lifting frame 9. The rotating frame 34 is fixedly installed on the tilting rotating shaft 36 and rotates with the tilting rotating shaft 36. The rotating drive device 35 includes a rotating drive motor 38 mounted on the lower lifting frame 28 and a chain drive device 39 located between the rotating drive motor 38 and one end of the tilting rotating shaft 36. The chain drive device 39 uses an existing double-row chain structure for transmission. A torque limiter is installed on the shaft end of the rotating drive motor 38 to prevent motor overload.

[0058] A tilting angle plate 40 is fixedly installed on the lower lifting frame 28, and a proximity switch 41 is installed on the tilting angle plate 40 to control the tilting angle of the rotating frame 34. Of course, proximity switches can also be installed at the rising and falling positions of the lifting frame 9 to control the lifting stroke.

[0059] The rotating frame 34 has an inlet 42 on its side for the material box 3 to enter, and a discharge port 43 on its top surface. A discharge guiding assembly is fixedly installed on the discharge side of the discharge port. The discharge guiding assembly includes a bottom guiding component 44 and a side guiding component 45. The bottom guiding component 44 and the side guiding component 45 can be plate parts or profile parts assembled together (the gap formed by the assembly is larger than the size of the material being dumped). The bottom guiding component 44 is fixedly installed on the rotating frame 34 below the discharge port when the material is being dumped. The side guiding component 45 is fixedly installed on the rotating frame 34 on both sides of the bottom guiding component 44 to guide the dumping of the material and prevent leakage of the material during the dumping process.

[0060] The walking mechanism 7 includes a walking drive motor 46, four walking wheels 47, and a walking transmission shaft assembly 48. The walking drive motor 46 is mounted on the walking base frame 5 via a motor support 49, and the four walking wheels 47 are respectively mounted at the four corners of the bottom of the walking base frame 5. The walking transmission shaft assembly 48 is installed between the walking wheels 47 for transmission. The walking drive motor 46 is connected to the walking transmission shaft assembly 48 via a reducer. The walking drive motor 46 drives the reducer and the walking transmission shaft assembly 48 in sequence, thereby driving the rotation of the walking wheels 47 and realizing the movement of the entire unloading trolley.

[0061] The travel drive shaft assembly 48 includes a first shaft segment 50, a second shaft segment 51, and an intermediate connecting shaft 52. The first shaft segment 50 and the second shaft segment 51 are respectively connected to two facing travel wheels 47. The first shaft segment 50 is connected to one end of the intermediate connecting shaft 52 through a first coupling 53, and the second shaft segment 51 is connected to the other end of the intermediate connecting shaft 52 through a second coupling 54. The intermediate connecting shaft 52 includes shaft connecting segments 55 at both ends and an intermediate sleeve segment 56 fixedly connected between the two shaft connecting segments. By setting up a multi-segment travel drive shaft assembly 48, the processing difficulty of long shaft assemblies can be reduced, assembly and use can be convenient, and the length of the intermediate sleeve segment can be selected according to the distance between different travel wheels 47, thereby enhancing assembly flexibility.

[0062] A maintenance platform 57 is fixedly installed above the walking base frame 5, which extends upward to the lifting mechanism 8, for maintenance by staff.

[0063] This invention enables industrial-scale automatic lifting, tilting, and unloading of materials without manual operation. The trolley is driven by a motor to produce two drive wheels, which in turn drive two driven wheels to achieve the movement of the entire trolley. The lifting and tilting unloading trolley uses a motor-driven sprocket and a chain to achieve automatic lifting and tilting of the trolley and automatic entry and exit of the material box 3. The lifting and tilting positions and the positioning position of the material box 3 are precisely controlled by proximity switches. The operation steps of this new type of automatic moving lifting and tilting unloading trolley are as follows: The material box 3 enters the rotating frame 34 of the tilting drive mechanism 4 through the air conveyor roller, and stops at the predetermined position by the proximity switch after deceleration. The lifting mechanism 8 begins to descend and stops at the predetermined position by the proximity switch after deceleration. The rotating drive device 35 starts to run, rotating the rotating frame 34 with the material box 3 clockwise. After deceleration, it stops at the predetermined position by the proximity switch, and the material in the material box 3 is tilted out. After unloading, the rotating frame 34 with the material box 3 rotates counterclockwise to its original position. The lifting mechanism 8 begins to rise and stops at the predetermined position by the proximity switch after deceleration. The material box 3 enters the air conveyor roller in the opposite direction through the conveyor roller 33, thereby realizing the material transfer and tilting between the high and low production lines.
