Description

Technical Field

[0001] This utility model relates to a cargo transfer device, specifically an electric transfer vehicle. Background Technology

[0002] In warehousing and freight transportation, corresponding transfer equipment is used to handle and load goods. Currently, traditional transfer equipment includes forklifts and manual trailers. Forklifts are large, expensive to purchase, and require a license to operate, which significantly limits their use. While manual trailers are small and flexible, they require high-intensity work and are slow, severely impacting the efficiency of goods transfer and loading. Utility Model Content

[0003] To address the aforementioned problems, this utility model designs an electric transfer vehicle that organically combines electric drive with a cargo trolley, effectively reducing workload and improving transfer efficiency. It features a simple and practical structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electric transfer vehicle is characterized by comprising a rear-mounted power mechanism and a front-mounted cargo trolley. The power mechanism includes a footboard for the operator to stand on, with two drive wheels below the footboard and a bridge plate at the front end of the footboard, the front end of which is movably hinged to the cargo trolley. The cargo trolley includes a cargo platform with at least three non-coordinated rollers below it. A mounting base is located on one rear side of the cargo platform, housing a drive battery that is electrically connected to the drive wheels. An operating lever is located on each of the rear sides of the cargo platform, with an operating handle at the top of each lever.

[0006] More specifically, the aforementioned loading and unloading plate is equipped with a quick loading and unloading mechanism. This mechanism includes a rotating shaft located below the loading plate. At least two hooks with raised heads are spaced apart on the rotating shaft. A torsion spring is provided on the rotating shaft. In the initial state, the torsion spring's restoring force causes the raised heads of the hooks to extend from the connecting holes of the loading plate to the surface of the loading plate and hook the bottom of the goods for positioning. One end of the rotating shaft is equipped with a rocker arm, and the rear end of the rocker arm is equipped with a small roller. The small roller is movably connected to an elongated hole on the front end of a connecting arm. The middle part of the connecting arm is movably hinged to a connecting seat at the bottom of the loading plate. The tail end of the connecting arm extends backward out of the loading plate and is equipped with a quick loading and unloading mechanism pedal. When the quick loading and unloading mechanism pedal is pressed, the rotating shaft can be rotated counterclockwise, causing the raised heads on the hooks to sink and detach from the surface of the loading plate, thus achieving automatic separation from the bottom of the goods.

[0007] More specifically, limit barriers are installed on both sides of the rear of the aforementioned cargo platform.

[0008] More specifically, the aforementioned operating handle is equipped with a power switch for the power mechanism.

[0009] More specifically, the aforementioned control handle is equipped with a controller for driving the wheels forward or backward.

[0010] More specifically, the aforementioned control handle is equipped with a speed adjustment button for the drive wheel.

[0011] More specifically, the aforementioned control handle is equipped with a brake button for the drive wheel.

[0012] This utility model designs an electric transfer vehicle that organically combines a rear-mounted power mechanism and a front-mounted cargo trolley into one unit via a bridge plate. In use, the operator stands on the pedal platform of the rear-mounted power mechanism, using the drive wheels to move the cargo trolley quickly. Simultaneously, the operator uses both hands to control two handles, enabling start / stop, adjustment of forward / backward direction, speed, and emergency braking as needed.

[0013] The loading platform is equipped with a quick loading and unloading mechanism. In use, the front end of the loading trolley is inserted directly under the goods or other loading trolleys, and then the upper protrusion of the hook is raised to hook the bottom of the goods for quick positioning and connection. When the goods need to be separated after moving into position, the pedal of the quick loading and unloading mechanism is pressed down to make the upper protrusion of the hook sink down and separate from the bottom of the goods, and the drive wheel is controlled to move backward, driving the loading trolley to move backward in sync to achieve the separation operation of the vehicle and the goods.

[0024] like Figure 1-4 As shown, an electric transfer vehicle includes a rear-mounted power unit 1 and a front-mounted cargo trolley 2.

[0025] The power mechanism 1 includes a footboard 11 for the operator to stand on, and two drive wheels 12 are provided below the footboard 11.

[0026] A bridge plate 3 is provided at the front end of the pedal 11. The rear end of the bridge plate 3 is fixedly connected to or hinged to the pedal 11, and the front end of the bridge plate 3 is movably hinged to the cargo trolley 2.

[0027] The cargo trolley 2 includes a cargo platform 21, and at least three non-coordinated rollers 22 are provided below the cargo platform 21. In this figure, three rollers 22 are provided, one on the front and two side by side on the rear. In practice, four or more rollers may also be provided.

[0028] A mounting base 23 is provided on one side of the rear of the carrier plate 21. The mounting base 23 contains a driving battery 4, which can be a lead-acid battery or a lithium battery. A corresponding charging interface is provided on the side of the mounting base. The driving battery 4 is electrically connected to the driving wheel 12.

[0029] Each of the rear sides of the loading platform 21 is provided with an operating lever 24, and the top of the operating lever 24 is provided with an operating handle 25. Here, in order to realize the flexible use of the transfer vehicle, the operating handle 25 is provided with a variety of operating switches, such as a power switch 251 for controlling the operation of the power mechanism 1, a controller 252 for controlling the forward or backward movement of the drive wheel 12, a speed adjustment button 253 for adjusting the speed of the drive wheel 12, and a brake operation button 254 for stopping the drive wheel 12, etc.

[0030] In addition, to prevent the goods from falling during the transfer process, limit railings 26 are provided on both sides of the rear of the loading platform 21. These railings can effectively limit the loaded goods and prevent them from falling during use.

[0031] In summary, the electric transfer vehicle designed in this utility model organically combines the rear-mounted power mechanism 1 and the front-mounted cargo trolley 2 into one unit via the bridge plate 3. The driver and user of this transfer vehicle does not require special training and can be used immediately upon arrival.

[0032] When in use, the operator stands on the platform of the pedal 11 of the rear-mounted power mechanism 1 and uses the drive wheel 12 of the power mechanism 1 to move the cargo trolley 2 quickly. At the same time, the operator controls the two operating handles 25 with both hands to start, stop, turn, adjust forward and backward direction, speed and emergency braking as needed.

[0033] Furthermore, to improve the transfer efficiency of the transfer vehicle, a quick loading and unloading mechanism 5 is provided on the loading platform 21. This quick loading and unloading mechanism includes a rotating shaft 51 located below the loading platform 21. At least two hooks 52 with protrusions 521 on their heads are spaced apart on the rotating shaft 51. This illustration only describes the structure with two hooks 52; in practice, three or more hooks can be provided as needed. A torsion spring is provided on the rotating shaft 51. In the initial state, the torsion spring's restoring force causes the protrusions 521 of the hooks 52 to extend from the connecting hole 211 of the loading platform 21 to the surface of the loading platform, hooking the bottom of the goods for positioning.

[0034] One end of the rotating shaft 51 is provided with a rocker arm 53, and the rear end of the rocker arm 53 is provided with a small roller 54. The small roller 54 is movably connected to the elongated hole 551 on the front end of a connecting arm 55. The middle part of the connecting arm 55 is movably hinged to the connecting seat 212 at the bottom of the carrying plate 21. The tail of the connecting arm 55 extends backward out of the carrying plate and is provided with a quick loading and unloading mechanism pedal 56.

[0035] In use, pressing the quick-loading mechanism pedal 56 causes the rotating shaft 51 to rotate counterclockwise, which in turn causes the upper protrusion 521 of the hook 52 to sink. At this time, the front end of the cargo trolley 2 is directly inserted under the goods or other cargo trolleys. Then, the quick-loading mechanism pedal 56 is released, causing the upper protrusion 521 of the hook 52 to rise and hook the bottom of the goods for quick positioning and connection. When the goods need to be separated after moving into position, pressing the quick-loading mechanism pedal 56 again causes the upper protrusion 521 of the hook 52 to sink and separate from the bottom of the goods, and controls the drive wheel 12 to move backward, driving the cargo trolley 2 to move backward synchronously to achieve the separation operation of the vehicle and the goods.

[0036] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
