Abstract

Technical Field
[0001] This application relates to the technical field of conveying mechanisms, and in particular to a lifting heavy-duty roller conveyor mechanism. Background Technology
[0002] In the existing logistics field, it is often necessary to vertically lift and transport goods.
[0003] However, existing vertical lifting conveyors are generally cam-type or hydraulic cylinder-type. Cam-type lifting conveyors have a short lifting stroke, making them unsuitable for conveying requirements with large height differences. Hydraulic cylinder-type lifting conveyors often require four hydraulic cylinders to lift, which is not only costly but also complex in structure, requiring an electrical control device to synchronize the lifting of the four hydraulic cylinders. This makes them unsuitable for complex factory environments and also results in a higher failure rate. Utility Model Content

Detailed Implementation
[0022] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0023] This application discloses a lifting heavy-duty roller conveyor mechanism. (Refer to...) Figure 1-3 A lifting heavy-duty roller conveyor mechanism includes a housing 1 and a conveying mechanism;
[0024] The housing 1 is used to support and install the overall device;
[0025] The interior of the box 1 is hollow. Multiple fixed plates 10 are fixedly connected to the bottom side of the box 1. Each fixed plate 10 has a movable groove 20 on its side wall. Each movable groove 20 has a support plate 6 slidably installed inside it. The top of the support plate 6 moves through the fixed plate 10 and the side wall of the box 1 and extends to the outside.
[0026] Two bidirectional lead screws 19 are rotatably installed on the bottom of the inner side wall of the housing 1. Two slides 15 are threaded through the side walls of the two bidirectional lead screws 19. The slides 15 are connected to the support plate 6 through a connecting assembly. The connecting assembly includes a first connecting seat 11 and a second connecting seat 12. Two first connecting seats 11 are fixedly connected to the opposite side of the two slides 15. A second connecting seat 12 is fixedly connected to one side of the bottom of the multiple support plates 6. The corresponding first connecting seats 11 and second connecting seats 12 are hinged to each other through a connecting plate 13.
[0027] A drive motor 9 is fixedly installed on one side of the housing 1. The drive motor 9 is connected to the bidirectional lead screw 19 through a drive assembly. The drive assembly includes a connecting shaft 16, a worm 17 and two worm wheels 18. The connecting shaft 16 is rotatably installed inside the housing 1. The worm 17 is fixedly sleeved on the side wall of the connecting shaft 16. The worm wheels 18 that mesh with the worm 17 are fixedly sleeved on the side walls of the two bidirectional lead screws 19. The output end of the drive motor 9 is fixedly connected to one end of the connecting shaft 16.
[0028] The conveying mechanism is set on the upper surface of the box 1 for conveying goods. The tops of multiple support plates 6 are all connected to the conveying mechanism. The conveying mechanism includes a frame 2 and multiple conveying rollers 3. The tops of multiple support plates 6 are fixedly connected to the frame 2. Multiple conveying rollers 3 are rotatably installed at equal intervals on the inner side wall of the frame 2. A motor 5 is fixedly installed on one side of the frame 2, and a transmission box 4 is fixedly installed on the other side of the frame 2. The output end of the motor 5 is fixedly connected to one end of one of the conveying rollers 3. Adjacent two conveying rollers 3 are connected by a sprocket (not shown in the figure) and a chain (not shown in the figure). The sprocket and the chain are both set in the transmission box 4.
[0029] A controller 7 is fixedly installed on one side of the housing 1, which is electrically connected to the drive motor 9 and the motor 5 respectively, so as to realize intelligent control of the equipment.
[0030] The implementation principle of the lifting heavy-duty roller conveyor mechanism in this application embodiment is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. When in use, goods are placed on the conveyor rollers 3 of the conveyor mechanism. The controller 7 starts the motor 5, which drives one of the conveyor rollers 3 to rotate. Through the transmission action of sprockets and chains, multiple conveyor rollers 3 rotate synchronously, achieving horizontal conveying of goods. When it is necessary to lift goods, the controller 7 starts the drive motor 9. The output end of the drive motor 9 drives the connecting shaft 16 to rotate. The worm gear 17 on the connecting shaft 16 rotates synchronously, and the two worm wheels 18 meshing with the worm gear 17 respectively drive the corresponding bidirectional lead screws 19 to rotate. When the bidirectional lead screw 19 rotates, the sliding seat 15 on its surface moves towards or away from the lead screw under the action of the thread. Through the transmission of the first connecting seat 11, the connecting plate 13, and the second connecting seat 12, it pushes the support plate 6 to slide up and down along the movable groove 20 of the fixed plate 10. When the slides 15 move in opposite directions, the connecting plate 13 pushes the support plate 6 upward, causing the frame 2 and conveyor roller 3 to rise as a whole, thus lifting the goods. When the slides 15 move towards each other, the support plate 6 descends under the action of gravity, and the conveying mechanism returns to its initial position. Throughout the process, multiple support plates 6 move synchronously to ensure the smooth lifting and lowering of the conveying mechanism and prevent the goods from tilting.
[0031] During this process, the lifting heavy-duty roller conveyor mechanism provides stable support through the housing 1, and uses the drive motor 9 to drive the bidirectional lead screw 19 to rotate to realize the lifting and lowering of the conveyor mechanism. It works in conjunction with the conveyor roller 3 to complete the horizontal conveying and vertical lifting of goods. The entire process is intelligently controlled by the controller 7. At the same time, the overall structure is relatively simple and very convenient to use, which improves the practicality of the device.
[0032] Here, the models of electrical components involved in this application can be selected according to the actual situation. They are existing technologies and widely used in society, so they will not be elaborated on further.
[0033] The thread between the double-acting lead screw 19 and the slide 15 can achieve self-locking. The self-locking condition depends on the helix angle, the coefficient of friction, and the load applied. The self-locking condition can be calculated using the following formula: Self-locking condition = Coefficient of friction × tan(helix angle) ≥ 1. When this condition is met, the threaded connection is self-locking. When the lead angle (λ) of the worm 17 is less than the friction angle (φ) of the contact surface between the worm wheel 18 and the worm 17, the transmission system between the worm wheel 18 and the worm 17 can achieve self-locking. Through an external power device, the worm 17 can be driven to rotate clockwise and counterclockwise, thereby achieving clockwise and counterclockwise rotation of the worm wheel 18. The above content is all prior art. In practical applications, the corresponding self-locking angle can be set according to the friction coefficient of the material, which will not be elaborated here.
