Description

Technical Field

[0001] This utility model relates to the field of material handling tractor technology, and in particular to a material handling tractor suitable for narrow spaces. Background Technology

[0002] In modern industrial production, logistics warehousing, and many other fields, the handling of sheet materials is a common and important task. Traditional methods of handling sheet materials mostly rely on large handling equipment or small handling tractors. Large handling equipment is usually suitable for spacious areas and can efficiently complete the handling of large quantities of sheet materials, but due to its large size, it cannot enter some narrow passages or spaces for operation.

[0003] While small material handling tractors are relatively flexible and can be pushed and transferred by operators, most of them have a fixed structure. When faced with narrow aisles in warehouses or densely packed equipment areas in workshops, these fixed-structure tractors become inadequate. They not only struggle to move smoothly but also lack the adaptability to different space sizes and material load requirements, reducing work efficiency and equipment versatility. This necessitates frequent changes of handling tools in spaces of varying sizes, increasing handling costs and time. Therefore, we propose a material handling tractor suitable for confined spaces to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a material handling tractor suitable for confined spaces.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A material handling tractor suitable for confined spaces includes a platform with a cavity inside. A rotating device is installed on one side of the cavity, and two studs are installed on the rotating device. A pushing mechanism is threaded onto the studs. One end of the pushing mechanism passes through the side wall of the platform and extends to one side of the platform. A support plate is connected to one end of the pushing mechanism. Folding frames are rotatably connected to both sides of the support plate. One end of a folding frame on the same side is rotatably connected to one side of the platform. A support plate is inserted into the upper end of the support plate, and one side of the lower end of the support plate is slidably connected to the upper end of the platform. Casters are rotatably connected to both the lower ends of the support plate and the platform.

[0007] Preferably, the rotating device includes a servo motor fixed to one side of the cavity, a reducer connected to the end of the output shaft of the servo motor, and two studs connected to both sides of the reducer via couplings, with one end of the studs rotatably connected to one side of the cavity.

[0008] Preferably, the pushing mechanism includes a movable plate threaded onto a stud, and two movable rods are fixed to one side of the movable plate. The two movable rods pass through the side wall of the support platform and are fixed to one side of a support plate on the same side.

[0009] Preferably, the upper end of the support plate is provided with two slots on both sides, and the lower end of the bearing plate is fixed with two rods on both sides, with the two rods on the same side inserted into the two slots on the same side.

[0010] Preferably, the upper end of the support platform is provided with sliding grooves on both sides, and the lower end of one side of the support plate is fixed with sliders on both sides, with one slider on the same side engaging with one sliding groove on the same side.

[0011] Preferably, a push rod is fixed on one side of the support platform.

[0012] In this utility model, when it is needed for use:

[0013] 1. Moving Operation: The operator holds the push rod and pushes the entire tractor. Using the casters installed on both sides of the support plate and the lower end of the platform, the tractor can be moved on the ground to the location where the sheet material needs to be transported.

[0014] 2. Space and load capacity adjustment: When encountering spaces of different specifications or when the load capacity needs to be adjusted, start the rotating equipment. The servo motor fixed on one side of the cavity of the bearing platform starts to work. The reducer connected to the end of its output shaft adjusts the motor speed to provide appropriate torque. The two sides of the reducer drive two studs to rotate through couplings respectively.

[0015] Since the movable plate is threaded onto the stud, the rotation of the stud will cause the movable plate to move along the axial direction of the stud. The two movable rods fixed on one side of the movable plate move together with the movable plate. The movable rods pass through the side wall of the support platform and push the support plate.

[0016] At the same time, the folding frame connected to both sides of the support plate begins to fold or unfold. If the stud rotates and moves the moving plate towards the center, the folding frame folds, causing the support plates on both sides to move closer to the center. At this time, the two load-bearing plates installed on the support plate also move towards the center, reducing the overall width to adapt to narrower spaces. Conversely, if the stud rotates and moves the moving plate to the sides, the folding frame unfolds, and the support plate and load-bearing plate move to the sides, increasing the overall width and increasing the load capacity as needed.

[0017] During the movement of the support plate, the insert rods on both sides of the lower end of the support plate slide in the slots at the upper end of the support plate, ensuring the connection stability between the support plate and the support plate; the slider at the lower end of one side of the support plate slides in the groove at the upper end of the support platform, further ensuring the smoothness and stability of the movement of the support plate; the inserted support plate can also be flexibly replaced as needed.

[0018] 3. Material handling: After adjusting the position and width of the support plate, place the sheet material on the support plate, hold the push rod again, and move the tractor to the designated location to complete the material handling.

[0019] This utility model has the following advantages:

[0020] 1. It can be adjusted according to different space specifications, which enhances the equipment's mobility and adaptability in different environments and avoids the trouble of frequently changing handling tools due to space limitations;

[0021] 2. The load capacity can be flexibly adjusted according to actual material handling needs, improving the practicality and flexibility of the equipment;

[0022] 3. It can ensure the stability of the load-bearing capacity, increase the load capacity, and is also convenient to use;

[0023] In summary, this utility model can be adjusted according to different space specifications, enhancing the equipment's mobility and adaptability in different environments, avoiding the trouble of frequently changing handling tools due to space limitations, and also enabling flexible adjustment of the load capacity according to actual material handling needs, thus improving the equipment's practicality and flexibility.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figure 1-5 A material handling tractor suitable for narrow spaces includes a carrying platform 6 with a cavity inside. A rotating device is installed on one side of the cavity. Two studs 12 are installed on the rotating device. A pushing mechanism is threaded onto the studs 12. One end of the pushing mechanism passes through the side wall of the carrying platform 6 and extends to one side of the carrying platform 6. A support plate 4 is connected to one end of the pushing mechanism. Folding frames 2 are rotatably connected to both sides of the support plate 4 to ensure stability when folded.

[0032] One end of a folding frame 2 on the same side is rotatably connected to one side of the support platform 6. The upper end of the support plate 4 is inserted with a support plate 13. The lower end of the support plate 13 is slidably connected to the upper end of the support platform 6. Both sides of the lower end of the support plate 4 and the support platform 6 are rotatably connected with casters 7, and the casters 7 are equipped with a brake mechanism.

[0033] The rotating device includes a servo motor 10 fixed on one side of the cavity. The output shaft of the servo motor 10 is connected to a reducer 11. The two sides of the reducer 11 are connected to two studs 12 respectively through a coupling 16. One end of the stud 12 is rotatably connected to one side of the cavity. The servo motor 10 has the advantages of high precision and controllability, and can provide power accurately, enabling forward and reverse rotation of the output shaft. The function of the reducer 11 is to adjust the motor speed to provide appropriate torque. The coupling 16 ensures stable power transmission.

[0034] The pushing mechanism includes a movable plate 9 threaded onto a stud 12. Two movable rods 3 are fixed on one side of the movable plate 9. The two movable rods 3 pass through the side wall of the support platform 6 and are fixed on one side of a support plate 4 on the same side. When the stud 12 rotates, the movable plate 9 will move along the axial direction of the stud 12, thereby driving the movable rods 3 and the support plate 4 to move.

[0035] The upper end of the support plate 4 is provided with two slots 5 on both sides, and the lower end of the bearing plate 13 is fixed with two rods 14 on both sides. The two rods 14 on the same side are inserted into the two slots 5 on the same side. The insertion method ensures the connection stability between the bearing plate 13 and the support plate 4, and also facilitates the replacement of the bearing plate 13.

[0036] The upper end of the support platform 6 is provided with sliding grooves 8 on both sides, and the lower end of the support plate 13 is fixed with sliders 15 on both sides. A slider 15 on the same side is engaged in a sliding groove 8 on the same side. The cooperation between the sliding groove 8 and the slider 15 further ensures the smoothness and stability of the movement of the support plate 13.

[0037] A push rod 1 is fixed on one side of the support platform 6, which facilitates the operator to move the tractor.

[0038] In this utility model, when it is needed for use:

[0039] 1. Moving operation: The operator holds the push rod 1 and pushes the entire tractor. Using the casters 7 installed on both sides of the lower end of the support plate 4 and the bearing platform 6, the tractor can be moved on the ground to the location where the sheet material needs to be transported.

[0040] 2. Space and load capacity adjustment: When encountering spaces of different specifications or when the load capacity needs to be adjusted, start the rotating equipment. The servo motor 10 fixed in one side of the cavity of the bearing platform 6 starts to work. The reducer 11 connected to the end of its output shaft adjusts the motor speed to provide appropriate torque. The two sides of the reducer 11 drive the two studs 12 to rotate through the coupling 16 respectively.

[0041] Since the movable plate 9 is threaded onto the stud 12, the rotation of the stud 12 will cause the movable plate 9 to move along the axial direction of the stud 12. The two movable rods 3 fixed on one side of the movable plate 9 move together with the movable plate 9. The movable rods 3 penetrate the side wall of the support platform 6 and push the support plate 4.

[0042] At the same time, the folding frame 2, which is rotatably connected to both sides of the support plate 4, begins to fold or unfold. If the stud 12 rotates and moves the moving plate 9 toward the center, the folding frame 2 folds, causing the support plates 4 on both sides to move toward the center. At this time, the two bearing plates 13 installed on the support plate 4 also move toward the center, reducing the overall width to accommodate narrower spaces. Conversely, if the stud 12 rotates and moves the moving plate 9 to both sides, the folding frame 2 unfolds, and the support plate 4 and bearing plates 13 move to both sides, increasing the overall width and increasing the load capacity as needed.

[0043] During the movement of the support plate 13, the insert rods 14 on both sides of the lower end of the support plate 13 slide in the slots 5 at the upper end of the support plate 4, ensuring the connection stability between the support plate 13 and the support plate 4; the slider 15 at the lower end of one side of the support plate 13 slides in the groove 8 at the upper end of the support platform 6, further ensuring the smoothness and stability of the movement of the support plate 13, and the inserted support plate 13 can also be flexibly replaced as needed.

[0044] 3. Material handling: After adjusting the position and width of the bearing plate 13, place the sheet material on the bearing plate 13, hold the push rod 1 again, and move the tractor to the designated location to complete the material handling.

[0045] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
