Description

Technical Field

[0001] This utility model relates to the field of mixer truck technology, and in particular to a novel electric mixer truck with a lifting ladder. Background Technology

[0002] With the promotion and application of new energy technologies, new energy technologies have also been applied to heavy vehicles, including electric mixer trucks. Electric mixer trucks include electric motors, battery packs, and electronic control systems. Driven by electric energy, electric power not only saves money but also achieves the goal of environmental protection. A ladder is usually installed at the rear of the electric mixer truck to facilitate workers to observe the mixing process.

[0003] The ladder on the electric mixer truck is designed as a lifting ladder, which is also electrically controlled. A search revealed Chinese patent CN217575029U, titled "An Electric Lifting Ladder for a Concrete Mixer Truck," which describes a system installed on the rear end of a concrete mixer truck, including a lifting support, a sliding mechanism, and a foldable lifting platform connected to the sliding mechanism. The lifting support is vertically supported between the support arm and the sub-beam of the concrete mixer truck, and is arranged along the length of the truck. The sliding mechanism includes a back plate that can move up and down along the lifting support under the drive of a reduction motor. Roller sets slidably connected to the lifting support are mounted on both ends of the front face of the back plate. The reduction motor is fixed to one end of the back plate, and a gear is mounted on the output shaft of the reduction motor after passing through the back plate. A rack meshing with the gear is fixed to one side wall of the lifting support. The folding lifting platform includes a backrest connected to the back panel, and a folding pedal at the lower end of the backrest that can be rotated and opened / closed with a hinge axis. This achieves the effect of "effectively saving space at the rear of the vehicle, while making the lifting platform foldable. When in use, the folding lifting platform can be lowered, and during driving, it can be folded up to prevent concrete mixer trucks from bumping or scratching each other. Additionally, it does not obstruct the driver's rear view while driving, thus enhancing safety." However, it was found during use that the lower support cannot extend downwards to the ground. Because the road conditions in which the vehicle is used are often poor, designing the lower support too low would affect its normal use. Therefore, the entire lower support is designed to be relatively high. A higher lower support design makes the folding lifting platform quite tall, making it difficult to climb onto initially, requiring considerable effort, and thus not suitable for daily use.

[0004] Therefore, how to provide a new type of electric mixer truck with lifting ladder is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to propose a novel electric mixer truck with a lifting ladder. This invention solves the problem that the high height of the existing foldable lifting platform makes it difficult to climb onto the platform.

[0006] An electric mixer truck with a novel lifting ladder according to an embodiment of the present invention includes a folding lifting platform and two sets of guide rails. The folding lifting platform is movable on the surface of the two sets of guide rails. The folding lifting platform includes a lifting component, a lifting platform body, and rotating side rails. The lifting component is movable on the surface of the two sets of guide rails. The lifting platform body is rotatably connected to one side of the lifting component. There are two sets of rotating side rails, which are rotatably connected to the top of the lifting platform body. A storage ladder component is provided at the top of the lifting platform body away from the lifting component.

[0007] The storage ladder assembly includes a hinge shaft, a rotating frame, and a foot pedal. The hinge shaft is located at the top of the lifting platform body away from the lifting assembly. The rotating frame is rotatably connected to the hinge shaft, and the foot pedal is located on the rotating frame.

[0008] The top of the foot pedal is provided with anti-slip grooves.

[0009] A limiting plate is provided on the side of the lifting platform body away from the lifting component and near the bottom to limit the rotation frame. The side of the rotation frame is movably connected to the surface of the limiting plate.

[0010] A locking component for positioning the rotating frame is provided on the surface of the rotating frame at a position away from the hinge axis.

[0011] The locking assembly includes a limiting groove, a "U"-shaped clip, a first set of magnets, and a second set of magnets. The limiting groove is formed on the surface of the rotating frame, connecting the symmetrical two sides of the rotating frame. The "U"-shaped clip is movably locked inside the limiting groove. The first set of magnets includes two magnets of opposite polarity attracting each other. The two magnets are respectively located on the inner wall of the limiting groove and the side of the "U"-shaped clip. The second set of magnets also includes two magnets of opposite polarity attracting each other. The two magnets are respectively located on the inner wall of the limiting groove away from the magnets and on the inner side of the "U"-shaped clip.

[0012] The width of the rotating frame is less than the distance between the two sets of rotating side rails.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating a storage ladder component with a rotating design, one can ascend the folding lifting platform by rotating the storage ladder component to its lower position, and then stepping onto the platform using foot pedals. This solves the problem in existing technologies where the height of the folding lifting platform makes the process of ascending it difficult.

[0015] To improve the protective effect, after using the storage ladder assembly, the staff can manually rotate the assembly on the folding lifting platform to bring it close to the rotating side rail. The locking component can then be engaged to lock it onto the rotating side plate, thus sealing the entrance and forming a protective railing, thereby enhancing the protective function of the folding lifting platform.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0022] refer to Figure 1-3 In this embodiment, a folding lifting platform 1 and a double set of guide rails 2 are included. The folding lifting platform 1 is movable on the surface of the double set of guide rails 2. The folding lifting platform 1 is located at the rear of the electric mixer truck, mainly for observing the mixing of materials. The folding lifting platform 1 includes a lifting component 3, a lifting platform body 4, and rotating side rails 5. The lifting component 3 is movable on the surface of the double set of guide rails 2. The entire folding lifting platform 1 is a prior art component. For ease of description of its relationship with this solution, it is described in contrast. Other details will not be repeated. The lifting platform body 4 is rotatably connected to one side of the lifting component 3. There are two sets of rotating side rails 5, which are rotatably connected to the top of the lifting platform body 4.

[0023] A storage ladder assembly 6 is located at the top of the lifting platform body 4, away from the lifting component 3. The storage ladder assembly 6 includes a hinge shaft 7, a rotating frame 8, and a foot pedal 9. The hinge shaft 7 is located at the top of the lifting platform body 4, away from the lifting component 3. The rotating frame 8 is rotatably connected to the hinge shaft 7 and to the lifting platform body 4, allowing for easy rotation of the rotating frame 8. The foot pedal 9 is located on the rotating frame 8, and its top has an anti-slip groove 10 to enhance its anti-slip performance. A limiting plate 11 is located near the bottom of the side of the lifting platform body 4 away from the lifting component 3 to limit the rotation frame 8. The side of the rotating frame 8 is movably connected to the surface of the limiting plate 11. The limiting plate 11 positions the tilt of the rotating frame 8 when it is lowered, ensuring that the foot pedal 9 remains horizontal while the entire rotating frame 8 is tilted. During operation, the storage ladder assembly 6 is set as follows: Figure 1 As shown in the diagram, staff can then step onto the folding lifting platform 1 by stepping on the foot pedal 9, thus avoiding the situation where the folding lifting platform 1 is too high and difficult to climb onto.

[0024] refer to Figure 1-3 In this embodiment, a locking assembly 12 for positioning the rotating frame 8 is provided on the surface of the rotating frame 8 at a position away from the hinge axis 7. The locking assembly 12 includes a limiting groove 13, a "U"-shaped clip 14, a first set of magnets 15, and a second set of magnets 16. The limiting groove 13 is formed on the surface of the rotating frame 8, connecting the symmetrical two sides of the rotating frame 8. The "U"-shaped clip 14 is movably locked inside the limiting groove 13. The first set of magnets 15 includes two magnets of opposite polarity, which are respectively disposed on the inner wall of the limiting groove 13 and the side of the "U"-shaped clip 14. The second set of magnets 16 also includes two magnets of opposite polarity, which are respectively disposed on the inner wall of the limiting groove 13 at a position away from the magnets and on the inner side of the "U"-shaped clip 14. The width of the rotating frame 8 is less than the distance between the two sets of rotating side rails 5. The purpose is to rotate the rotating frame 8 so that the rotating plate is perpendicular to the lifting platform body 4 and positioned between the two sets of rotating side rails 5. When the worker climbs onto the lifting platform body 4, the worker squats down and manually pulls the rotating frame 8, causing the rotating frame 8 to rotate around the hinge axis 7 to a position perpendicular to the lifting platform body 4. At this time, the locking component 12 approaches the rotating side rail 5, and then the "U"-shaped card 14 is moved, causing the first set of magnets 15 on the "U"-shaped card 14 to separate and insert into the rotating side rail 5. When the "U"-shaped card 14 is fully inserted into the rotating side rail 5, the second set of magnets 16 attract each other and lock the position of the "U"-shaped card 14. At this time, the rotating frame 8 is stably connected to the rotating side rail 5 through the "U"-shaped card 14. The rotating frame 8 and the rotating side rail 5 surround the position of the worker, further improving the safety of the worker.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
