[0023] 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 embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figure 1 , Figure 3 , Figure 4 An embodiment of this utility model provides: a vertical transport trolley, including a base plate 1, a plurality of sleeves 13 fixedly connected to the rear side of the base plate 1, a back plate 14 fixedly connected to the adjacent side of the plurality of sleeves 13, a column 3 fixedly connected to the top of the plurality of sleeves 13, a worm gear 6 rotatably connected to the bottom of the plurality of column 3, a worm 4 slidably connected to the bottom of the column 3, a motor 5 fixedly connected to the bottom of the column 3, a threaded screw 7 fixedly connected to the inner wall of the plurality of worm gears 6, a rotating rod 8 threadedly connected to the bottom of the plurality of threaded screws 7, a wheel 9 fixedly connected to the bottom of the plurality of rotating rods 8, a first foot pad 10 fixedly connected to the bottom of the plurality of sleeves 13, and a lifting component provided on the top of the column 3.
[0025] Specifically, when using a handcart, push the handcart to the work position and load goods. Since the wheels 9 are in a grounded state, the vehicle is prone to movement during loading, which may cause injury to goods and personnel. By starting the motor 5, the output drives the worm gear 4 to rotate, which in turn drives the worm wheel 6 to rotate. The threaded rod 7 inside the worm wheel 6 will rotate together with the worm wheel 6, causing the rotating rod 8 at the bottom of the threaded rod 7 to rise along the thread. The wheel 9 at the bottom of the rotating rod 8 will rise together with the rotating rod 8 along the notch of the outer sleeve 13, so that the first foot pad 10 and the fixing block 12 fixed under the base plate 1 on the front side are grounded, making the handcart more stable on the ground and facilitating the loading and unloading of goods.
[0026] Reference Figure 2 The lifting assembly includes a handle 16, which is fixedly connected to the top of the pillar 3. Multiple pillars 3 are fixedly connected to the outer walls of electric push rods 15. Multiple sleeves 13 are fixedly connected to the outer walls of multiple support legs 11. A second foot pad 17 is fixedly connected to one end of the multiple support legs 11.
[0027] Specifically, when loading goods, the trolley is laid flat so that the support leg 11 and the second foot pad 17 at one end of the electric push rod 15 are grounded, making the trolley more stable when loading goods. Then, the goods are placed on the back panel 14 between the pillars 3, and the electric push rod 15 is activated to push the grounded second foot pad 17. At this time, the worker can use the handle 16 to lift the trolley. The electric push rod 15 can make the lifting process much easier, because the moment of lifting the trolley when it is loaded with heavy objects is the most strenuous. This can save a lot of time and effort.
[0028] Reference Figure 3 Multiple telescopic plates 2 are slidably connected to the inner wall of the base plate 1, and multiple fixing blocks 12 are fixedly connected to the bottom of the base plate 1.
[0029] Specifically, when the cargo is large, the contact surface can be increased by extending and retracting the telescopic plate 2 to protect the cargo. The function of the fixing block 12 is the same as that of the first foot pad 10, which makes the grounding more stable when stationary.
[0030] Reference Figure 4 The worm gear 4 is fixedly connected to the output end of the motor 5.
[0031] Specifically, motor 5 drives worm gear 4 to rotate, thereby lifting wheel 9.
[0032] Reference Figure 3 Multiple rotating rods 8 are slidably connected to the inner wall of sleeve 13, and wheels 9 are slidably connected to the inner wall of sleeve 13.
[0033] Specifically, sleeve 13 acts as a limit for rotating rod 8 and wheel 9 to prevent them from veering off course.
[0034] Reference Figure 2 The second foot pad 17 is fixedly connected to the output end of the electric push rod 15.
[0035] Specifically, the electric push rod 15 pushes the second foot pad 17 toward the ground to use the reaction force to lift the cart.
[0036] Reference Figure 4 Multiple worm gears 6 are meshed and connected to the tooth ends of the worm 4.
[0037] Specifically, the worm gear 4 drives the worm wheel 6 to rotate, which in turn causes the wheel 9 to rise and fall.
[0038] Reference Figure 5 Multiple telescopic plates 2 are rotatably connected to support rods 18 at their bottom.
[0039] Specifically, when the telescopic plate 2 is opened, the support rod 18 can be opened, which can improve the load-bearing capacity of the telescopic plate 2.
[0040] Working principle: When a vertical trolley is used to transport goods, the motor 5 is started, and the output end of the motor 5 drives the worm 4 to rotate. The worm 4 drives the worm wheel 6, which is meshed with its tooth end, to rotate. The threaded screw 7 fixed on the inner wall of the worm wheel 6 will rotate together with it. The thread of the threaded screw 7 drives the rotating rod 8 to rise. There is a wheel 9 at the bottom of the rotating rod 8. The wheel 9 will rise with the rotating rod 8, thereby grounding the first foot pad 10 to the fixed block 12 at the bottom of the base plate 1, so as to load the goods more stably.
[0041] When loading goods, the support rod 18 at the bottom of the front telescopic plate 2 is opened, and the internal support rod 18 will be grounded, making the telescopic plate 2 more stable and preventing it from tilting. When the trolley needs to be laid flat backward, the second foot pad 17 at one end of the support leg 11 and the electric push rod 15 will be grounded, making the trolley more stable. When the trolley is laid flat with goods, the second foot pad 17 at the bottom of the electric push rod 15 and the second foot pad 17 at the bottom of the support leg 11 will be grounded, which can support the trolley and make loading more stable. After the goods are placed on the back plate 14, the electric push rod 15 can be activated to lift the trolley when starting the vehicle. Since it is extremely difficult to lift the vehicle from the ground, lifting it saves the effort of manual lifting and facilitates subsequent transportation.
[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
