Technical Field

[0001] This utility model relates to the field of electric flatbed cart technology, and particularly to a trackless electric flatbed cart. Background Technology

[0002] Trackless electric flatbed carts are electric flatbed carts that can move freely without the need for fixed tracks. They overcome the limitations of traditional tracked electric flatbed carts, enabling flexible operation over a wider area.

[0003] Existing trackless electric flatbed carts typically have fixed clamps, which cannot clamp and secure goods of different sizes. Furthermore, the clamps are not flexible, making the goods susceptible to additional impacts and vibrations during movement, which can lead to damage.

[0004] Therefore, it is necessary to propose a trackless electric flatbed vehicle to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a trackless electric flatbed cart to solve the problems that the clamps are fixed and cannot clamp and fix goods of different sizes, and the clamps are not elastic, making the goods susceptible to additional impacts and vibrations during the movement of the goods, which can lead to damage.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model addresses the problems of fixed clamps, which cannot clamp and secure goods of different sizes, and the lack of elasticity in the clamps, making the goods susceptible to damage from additional impacts and vibrations during movement. It provides a solution such as… Figures 1-3 The trackless electric flatbed cart shown includes a flatbed cart body 1. A first clamping plate 2 is slidably disposed on one side of the top surface of the flatbed cart body 1, and a second clamping plate 3 is fixedly connected to the other side of the top surface of the flatbed cart body 1. Openings are provided on the side of the first clamping plate 2 and the second clamping plate 3 close to each other. Multiple first rollers 21 are rotatably disposed in the openings of the first clamping plate 2, and multiple second rollers 31 are rotatably disposed in the openings of the second clamping plate 3. Both the first rollers 21 and the second rollers 31 are elastic. When the flatbed cart body 1 transports goods, the goods on it will shake and move during transportation. Shaking and moving will cause the goods to be subjected to additional impact and vibration, resulting in damage to the goods.

[0025] It should be noted that the electric vehicle body 1 is a mature technology based on existing technology, and its specific structure will not be described in detail.

[0026] In this utility model, a first square cavity 43 is provided on one side of the electric cart body 1. A first bevel gear 41 and a second bevel gear 42 are provided inside the first square cavity 43. A second motor 4 is fixedly connected to the side wall of the electric cart body 1. The rotating shaft of the second motor 4 passes through the electric cart body 1 and is fixedly connected to the first bevel gear 41. The bottom end of the second rotating shaft 32 located in the middle is fixedly connected to the second bevel gear 42. The second bevel gear 42 meshes with the first bevel gear 41. When it is necessary to move the goods, the second motor 4 is turned on. The rotation of the second motor 4 drives the first bevel gear 41 to rotate. The rotation of the first bevel gear 41 drives the second bevel gear 42 to rotate. The rotation of the second bevel gear 42 drives the second rotating shaft 32 in the middle to rotate.

[0027] It should be noted that a second square cavity 46 is provided inside one side of the electric vehicle body 1. Multiple transmission wheels 44 and multiple transmission belts 45 are arranged inside the second square cavity 46. A transmission wheel 44 is fixedly connected to the bottom of the second rotating shaft 32 located on both sides. Two transmission wheels 44 are fixedly connected to the bottom of the multiple second rotating shafts 32 located in the middle. Adjacent transmission wheels 44 located at the same horizontal position are connected to the corresponding transmission belts 45. The rotation of the second rotating shaft 32 in the middle drives the rotation of the transmission wheel 44 in the middle. The cooperation of the transmission wheel 44 and the transmission belt 45 causes the other second rotating shafts 32 to rotate. The rotation of the second rotating shaft 32 drives the second rotating roller 31 to rotate. The cooperation of the second rotating roller 31 and the first rotating roller 21 moves the goods.

[0028] When using the electric cart body 1, the goods are placed on the top surface of the electric cart body 1, and the first clamping plate 2 is moved. The movement of the first clamping plate 2 drives the first rotating roller 21 to move. The first rotating roller 21 and the second rotating roller 31 move closer to each other to clamp the goods. Through the cooperation of the components, the first rotating roller 21 and the second rotating roller 31 can clamp and fix goods of different sizes, reduce friction and collision of goods during transportation, protect the quality and integrity of goods, and reduce the risk of goods falling off or tipping over during transportation, thereby enhancing the safety of transportation.

[0029] Furthermore, when the goods are placed on the top surface of the electric cart body 1, the second roller 31 is rotated. The cooperation between the second roller 31 and the first roller 21 moves the goods, thereby achieving smooth movement of the goods and making it easier to adjust them. At the same time, the cooperation between the second roller 31 and the first roller 21 makes it easier to handle the goods. Without additional manual assistance, the task of handling the goods can be easily completed, reducing the difficulty of operation and labor intensity.

[0030] It should be noted that the outer surfaces of the second roller 31 and the first roller 21 can be provided with anti-slip protrusions. Anti-slip protrusions are a mature technology in the prior art, not shown in the figure, and will not be described in detail here. At the same time, since the second roller 31 and the first roller 21 are elastically set (rubber or other materials can be used, and the specific materials are not limited), the elastic second roller 31 and the first roller 21 can absorb the vibration and impact during transportation, reducing the damage to the goods.

[0031] In this invention, a plurality of first rotating shafts 22 are rotatably arranged inside the opening of the first clamping plate 2, and the outer periphery of the first rotating shafts 22 is fixedly connected to the inner wall of the first rotating roller 21. A plurality of second rotating shafts 32 are rotatably arranged inside the opening of the second clamping plate 3, and the outer periphery of the second rotating shafts 32 is fixedly connected to the inner wall of the second rotating roller 31. The first rotating shafts 22 assist the rotation of the first rotating roller 21, and the second rotating shafts 32 assist the rotation of the second rotating roller 31, thus ensuring the normal operation of the first rotating roller 21 and the second rotating roller 31.

[0032] In this utility model, a sliding groove 24 is provided on the top surface of the electric cart body 1. A slider 25 is slidably connected inside the sliding groove 24. The top surface of the slider 25 is fixedly connected to the bottom surface of the first clamping plate 2. A lead screw 26 is rotatably provided inside the sliding groove 24. The lead screw 26 is threadedly connected to the slider 25. When the lead screw 26 is rotated, the slider 25 moves within the sliding groove 24. The movement of the slider 25 causes the first clamping plate 2 to move. The cooperation between the first clamping plate 2 and the second clamping plate 3 clamps the goods.

[0033] It should be noted that a first motor 23 is fixedly connected to the side wall of the electric cart body 1, and the end of the lead screw 26 passes through the side wall of the slide groove 24 and is fixedly connected to the shaft of the first motor 23; when the first motor 23 is turned on, the first motor 23 rotates and drives the lead screw 26 to rotate, and the subsequent moving and clamping work is completed through the cooperation of the components.
