Description

Technical Field

[0001] This utility model relates to the field of lifting device technology, specifically to a lifting and rotating mechanism. Background Technology

[0002] The lifting and rotating mechanism is a crucial component of AGVs, primarily responsible for the automated handling of material carts and racks, enabling automated docking. Common lifting and rotating mechanisms include scissor lifts and ball screw lifts. Scissor lift mechanisms, however, are inefficient and can negatively impact the AGV's battery life. Ball screw lift mechanisms suffer from low load-bearing capacity and require improvement. Utility Model Content

[0003] To address at least one of the aforementioned technical deficiencies, this utility model provides the following technical solution:

[0004] This application discloses a lifting and rotating mechanism, including a fixed plate, a support plate, and multiple sets of lead screw lifting mechanisms. Each lead screw lifting mechanism includes a lead screw and a mating nut. The nuts in each set of lead screw lifting mechanisms are connected to the support plate. The fixed plate is provided with a first gear, a second gear, a third gear, and a drive mechanism. The first gear and multiple third gears mesh with the side of the second gear, and all three are rotatably connected to the fixed plate. In the lead screw lifting mechanism, the lead screw is longitudinally arranged relative to the fixed plate and is connected to the third gear. The fixed plate is laterally provided with a drive mechanism. The drive mechanism has a hypoid gear reducer, and the output end of the hypoid gear reducer is connected to the first gear to drive it to rotate.

[0005] In this solution, a drive mechanism drives the first gear to rotate, which in turn drives the second gear to rotate, simultaneously causing the third gear to rotate. The screw rotates simultaneously, causing the support plate connected to the nut to rise and fall. The entire mechanism occupies a small volume, is highly efficient, and has a high load-bearing capacity, meeting the needs of vehicle-mounted applications.

[0006] In this solution, a hyperboloid gear reducer is connected to the motor part of the drive mechanism. The drive mechanism can be horizontally mounted on the fixed plate, which further reduces the longitudinal dimension of the lifting and rotating mechanism and facilitates vehicle installation and other requirements.

[0007] Furthermore, the drive mechanism includes a brushless motor and a hyperboloid gear reducer. The brushless motor is horizontally arranged on the fixed plate and its output end is connected to the input end of the hyperboloid gear reducer. The longitudinally oriented output end of the hyperboloid gear reducer is connected to the first gear. The brushless motor has higher efficiency and higher control precision. Using the brushless motor as a power source helps to improve lifting accuracy.

[0008] Furthermore, the first gear, the second gear, and the third gear are made of steel or titanium steel, and the outer diameter of the lead screw is 40mm. In this solution, the material of the gears is improved and a thicker lead screw is used, which helps to further increase the load and meet the lifting requirements of greater weight.

[0009] Furthermore, the support plate and the fixing plate are arranged in parallel.

[0010] Furthermore, the nut is located on the bottom surface of the support plate, making it convenient for the top surface of the support plate to connect with the object to be lifted.

[0011] Furthermore, the second gear has weight-reducing holes formed in the middle and the corresponding fixing plate and support plate, which helps to reduce weight.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model improves the structure of the lifting and rotating mechanism, which helps to improve efficiency and load-bearing capacity, and its longitudinal dimension is further reduced, making it convenient for vehicle installation. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Example 1

[0021] like Figure 1 , Figure 2As shown, the lifting and rotating mechanism includes a fixed plate 1, a support plate 2, and multiple sets of screw lifting mechanisms 3. The fixed plate 1 and the support plate 2 are common flat plates, arranged parallel to each other. The screw lifting mechanisms 3 are as follows... Figure 1 , Figure 2 The three sets shown provide relatively stable support at three points. Of course, you can also choose two, four, or more sets depending on your needs.

[0022] The screw lifting mechanism 3 is a common configuration consisting of a screw 31 and a matching nut 32. In the three screw lifting mechanisms, the nut 32 is connected to the support plate. For example, the nut is fixed to the bottom surface of the support plate by bolts, etc. The screw 31 passes through the nut 32 and is connected.

[0023] A first gear 6, a second gear 7, a third gear 8, and a drive mechanism 4 are mounted on the fixed plate 1. The first gear 6 and multiple third gears 8 mesh with the side of the second gear 7. The third gears 8 are paired one-to-one with the lead screw lifting mechanism 3. Therefore, in this example, there are also three sets of third gears 8. Figure 2 As shown, the third gear 8 is triangularly distributed, with the first gear 6 positioned between two adjacent third gears 8. The first gear 6, second gear 7, and third gear 8 are all pivotally connected to the fixed plate 1 via bearings, etc. In the screw lifting mechanism 3, the screw 31 is longitudinally positioned relative to the fixed plate 1, and its end is fixed to the third gear 8. The materials of the first, second, and third gears can be selected according to requirements; preferably, they are made of steel or titanium steel. The outer diameter of the screw is 40mm, which can significantly increase the load capacity of this lifting and rotating mechanism.

[0024] A drive mechanism 4 is horizontally mounted on the fixed plate 1. The drive mechanism 4 includes a brushless motor 41 and a hyperboloid gear reducer 42. The hyperboloid gear reducer 42 is fixed on the fixed plate 1, and the brushless motor 41 is horizontally mounted on the fixed plate 1. The output end of the brushless motor 41 is connected to the input end of the hyperboloid gear reducer 42. The longitudinally oriented output end of the hyperboloid gear reducer 42 is connected to the first gear 6. Under this configuration, the longitudinal dimension of the lifting and rotating mechanism is further reduced, which is convenient for vehicle installation. The brushless motor has higher efficiency and higher control precision, and the hyperboloid gear reducer has a larger output torque.

[0025] Driven by the brushless motor, the first gear rotates, the second gear rotates and synchronously drives the third gear to rotate, the lead screw rotates, and the nut drives the support plate to move up and down to achieve lifting.

[0026] To reduce weight, through holes, namely weight-reducing holes 5, are formed in the middle of the second gear 7 and at the corresponding fixed plate 1 and support plate 2. The diameter of the weight-reducing holes on the second gear, fixed plate, and support plate can be the same or different, depending on the requirements.

[0027] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
