Description

Technical Field

[0001] The utility model relates to the field of unmanned forklifts, and specifically relates to an unmanned forklift with a function of clamping goods. Background Technique

[0002] An unmanned forklift with a function of clamping goods generally refers to a forklift equipment integrating a goods clamping mechanism and unmanned handling technology. This kind of forklift not only has the basic functions of unmanned handling such as autonomous navigation, automatic control, and automatic path planning, but also is specially equipped with a goods clamping device to realize the stable handling of goods with specific shapes or easy to scatter.

[0003] At present, when an unmanned forklift with a function of clamping goods clamps goods, it generally clamps from top to bottom. However, due to the differences in the weight and volume of goods, as well as dynamic factors such as acceleration, deceleration, or turning during the handling process, the goods may fly out or shift from the clamping device due to inertia during transportation.

[0004] Regarding the above related technologies, the inventor believes that there are defects that may cause damage to goods and may pose safety risks to the handling environment or personnel. Content of the Utility Model

[0005] In order to improve the problems that may cause damage to goods and may pose safety risks to the handling environment or personnel when an unmanned forklift works, this application provides an unmanned forklift with a function of clamping goods.

[0006] The unmanned forklift with a function of clamping goods provided by this application adopts the following technical solutions;

Binding mechanisms are arranged on both sides of the vehicle body. The binding mechanisms include two mounting frames, and movable grooves are opened on both sides of the two mounting frames. Motors are arranged on the tops of the two mounting frames. The output ends of the motors penetrate through the mounting frames and are provided with lead screws. A plurality of sliding seats are slidably connected to the lead screws. There are two groups of the mounting frames and the sliding seats, and each group is provided with three sliding seats. One end of a flexible tightening belt is detachably connected to one side of one group of sliding seats through a fixing seat. A tightening seat is installed on one side of the other group of sliding seats;

[0008] The other end of the flexible tightening belt passes through the tightening seat. Tooth grooves are arranged on both sides of the inner wall of the flexible tightening belt. A gear is arranged on one side inside the tightening seat. A motor is arranged at the bottom of the gear, and the motor is used to drive the gear to rotate. The gear meshes with the tooth grooves, and the gear is used to tighten the flexible tightening belt.

[0009] By adopting the above technical solutions, the driverless forklift can automatically bundle and fix the goods, improving the stability and safety during the handling process. By driving the screw rod to rotate through the motor, the sliding seat can move up and down, thus conveniently adjusting the position and tightness of the flexible tightening belt.

[0010] Preferably, a locking block is provided on one side of the gear, and a cylinder is provided on one side of the locking block, and the output end of the cylinder is connected to the locking block.

[0011] By adopting the above technical solutions, when the flexible tightening belt is tightened to an appropriate degree, the cylinder can drive the locking block to move, firmly locking the flexible tightening belt to prevent it from loosening or falling off during the handling process. This design preferably enhances the stability and safety of the goods.

[0012] Preferably, a strain gauge is provided at the joint where the flexible tightening belt fits the goods. The strain gauge is used to sense the tightening condition of the goods, and the strain gauge can send an electrical signal to the control terminal in the vehicle body to activate the locking block to lock the flexible tightening belt.

[0013] By adopting the above technical solutions, the strain gauge can sense the tightening condition of the goods in real time and transmit the signal to the control terminal. When the goods are firmly tightened, the control terminal will activate the locking block for locking operation. This intelligent design improves the accuracy and efficiency of bundling.

[0014] Preferably, three flexible tightening belts are arranged at equal intervals from top to bottom.

[0015] By adopting the above technical solutions, multiple flexible tightening belts can distribute the binding force around the goods more evenly, ensuring that the goods will not be damaged or deformed due to uneven stress during the handling process. At the same time, the equal interval arrangement also helps to improve the stability and aesthetics of bundling.

[0016] Preferably, four Mecanum wheels are provided at the bottom of the vehicle body, and the four Mecanum wheels are arranged in a rectangular array.

[0017] By adopting the above technical solutions, the Mecanum wheels have the ability of omnidirectional movement, enabling the driverless forklift to turn and move flexibly in a narrow space. This design improves the adaptability and flexibility of the driverless forklift, enabling it to efficiently complete the handling task in various complex environments.

[0018] Preferably, a fork is provided at the rear end of the vehicle body, and a clamping buckle is driven by a cylinder inside the fork, and the clamping buckle is used to clamp the goods.

[0019] By adopting the above technical solution, the design of the fork and the clamping buckle enables the driverless forklift to conveniently clamp and fix the goods.

The design of the flexible tightening belt and the tightening seat structure enables the tightening belt to adapt to goods of different shapes and sizes, provide uniform clamping force, and firmly tighten the tightening belt through the gear design to ensure the stability of the goods during transportation. The addition of the locking block and the cylinder structure provides additional safety protection after the goods are clamped, preventing the tightening belt from loosening due to vibration or other external factors. The drive of the cylinder ensures the quick response of the locking block. At the same time, the combination of the strain gauge and the control terminal structure enables the forklift to monitor the tightening situation of the goods in real time and make intelligent adjustments according to the actual situation, improving the safety and efficiency of transportation. In summary, these structures work together to ensure the safety and stability of the goods during transportation;

[0022] 2. By setting up the clamping buckle in the present application, the clamping buckle driven by the cylinder preferably enhances this stability. The power provided by the cylinder enables the clamping buckle to quickly and accurately respond to the control instruction. When it is necessary to clamp the goods, the cylinder drives the clamping buckle to tighten, firmly fixing the goods on the fork, effectively preventing sliding or falling during handling. This design significantly improves the safety of goods handling. At the same time, the advantage of the clamping buckle for clamping goods is also obvious. Its design enables it to closely fit the surface of the goods and provide uniform clamping force, which helps to prevent the goods from shifting or being damaged due to inertia or vibration during handling.

Specific embodiments

[0028] The following is a further detailed description of this application in conjunction with the attached Figures 1-4 drawings.

[0029] The embodiment of this application discloses an unmanned handling forklift with a function of clamping goods.

[0030] Embodiment 1

[0031] Referring to Figure 1 , the unmanned forklift 1 includes a vehicle body 101, and binding mechanisms 3 are arranged on both sides of the vehicle body 101. The binding mechanism 3 includes two mounting frames 201, and movable slots 202 are opened on both sides of the two mounting frames 201. A motor 204 is arranged on the top of the two mounting frames 201, and the output end of the motor 204 penetrates through the mounting frame 201 and is provided with a lead screw 203. A plurality of sliding seats 205 are slidably connected to the lead screw 203. The mounting frame 201 and the sliding seat 205 are provided with two groups, and each group is provided with three sliding seats 205. One end of a flexible tightening belt 206 is detachably connected to one side of one group of sliding seats 205 through a fixed seat, and a tightening seat 208 is installed on one side of the other group of sliding seats 205; the other end of the flexible tightening belt 206 passes through the tightening seat 208. Tooth grooves 207 are arranged on both sides of the inner wall of the flexible tightening belt 206. A gear 209 is arranged on one side of the inside of the tightening seat 208, and a motor is arranged at the bottom of the gear 209, and the motor is used to drive the gear 209 to rotate. The gear 209 meshes with the tooth grooves 207, and the gear 209 is used to tighten the flexible tightening belt 206. The motor 204 drives the lead screw 203 to rotate, so that the sliding seat 205 can move up and down, thereby conveniently adjusting the position and tightness of the flexible tightening belt 206 to adapt to goods of different sizes and shapes.

[0032] Referring to Figure 3 . Figure 4, a locking block 211 is provided on one side of the gear 209, and a cylinder 210 is provided on one side of the locking block 211. The output end of the cylinder 210 is connected to the locking block 211. When the flexible tightening belt 206 is tightened to an appropriate degree, the cylinder 210 can drive the locking block 211 to move, firmly locking the flexible tightening belt to prevent it from loosening or falling off during handling. This design preferably enhances the stability and safety of the goods, ensuring that the goods will not be damaged or dropped due to the loosening of the tightening belt during handling.

[0033] Refer to Figure 1 , Figure 2 , a strain gauge 213 is provided at the joint where the flexible tightening belt 206 is tightened and fits the goods. The strain gauge 213 is used to sense the tightening condition of the goods, and the strain gauge 213 can send an electrical signal to the control terminal in the vehicle body 101 to activate the locking block 211 to lock the flexible tightening belt 206. The strain gauge 213 can sense the tightening condition of the goods in real time and transmit the signal to the control terminal. When the goods are firmly tightened, the control terminal will activate the locking block 211 to perform the locking operation. This intelligent design improves the accuracy and efficiency of bundling and reduces the possibility of manual intervention and misoperation.

[0034] Refer to Figure 1 , Figure 4 , three flexible tightening belts 206 are provided at equal intervals from top to bottom. Multiple flexible tightening belts 206 can more evenly distribute the binding force around the goods, ensuring that the goods will not be damaged or deformed due to uneven stress during handling. At the same time, the equal interval setting also helps to improve the stability and aesthetics of bundling, keeping the goods neat and compact during handling.

[0035] The implementation principle of Embodiment 1 is as follows: The driverless forklift 1 realizes the automatic bundling and stable handling of goods through the bundling mechanism 3 arranged on both sides of the vehicle body 101. The bundling mechanism 3 drives the screw rod 203 to rotate through the motor 204, causing the sliding seat 205 installed on the screw rod 203 to move up and down, adjusting the position and tightness of the flexible tightening belt 206. One end of the flexible tightening belt 206 is fixed on the sliding seat 205, and the other end meshes with the gear 209 through the tightening seat 208. When the flexible tightening belt 206 tightens the goods, the gear 209 rotates through the motor drive to further tighten the tightening belt. During the tightening process, the strain gauge 213 senses the tightening degree of the goods and transmits the corresponding signal to the control terminal in the vehicle body 101. When the control terminal detects that the goods have been firmly bundled, it will activate the cylinder 210 to drive the locking block 211 to lock the gear 209, thereby firmly locking the flexible tightening belt 206 to prevent loosening during the handling process, enabling the driverless forklift 1 to perform automatic and intelligent bundling operations on goods of different sizes and shapes, ensuring the stability and safety of the goods during the handling process. Through multiple equally spaced flexible tightening belts 206, the driverless forklift 1 can evenly distribute the bundling force, avoid damage or deformation caused by uneven stress on the goods, and improve the aesthetics and overall compactness of the goods, keeping them neat during transportation. The driverless forklift 1 significantly improves the handling efficiency and safety of the goods through the intelligent bundling mechanism and sensing system, reducing the possibility of manual intervention and misoperation.

[0036] Embodiment 2

[0037] Referring to Figure 1 、 Figure 2 Four Mecanum wheels 102 are arranged at the bottom of the vehicle body 101, and the four Mecanum wheels 102 are arranged in a rectangular array. The Mecanum wheels 102 have the ability of omnidirectional movement, enabling the driverless forklift to turn and move flexibly in a narrow space. This design improves the adaptability and flexibility of the driverless forklift, enabling it to efficiently complete handling tasks in various complex environments without the need to frequently adjust the direction or change the path.

[0038] Referring to Figure 1 、 Figure 4 A fork 103 is arranged at the rear end of the vehicle body 101. The inner side of the fork 103 is driven by a cylinder with a clamping buckle 104. The clamping buckle 104 is used to clamp the goods. The design of the fork 103 and the clamping buckle 104 enables the driverless forklift to conveniently clamp and fix the goods. The cylinder-driven clamping buckle 104 can quickly respond to control instructions and firmly clamp the goods to prevent slipping or shaking during the handling process. This design improves the handling ability and stability of the driverless forklift, ensuring the safety and integrity of the goods during the handling process.

[0039] The implementation principle of Embodiment 2 is as follows: The driverless forklift 1 moves to the side of the goods to be carried through the four Mecanum wheels 102 at its bottom. The forklift forks 103 at the rear end of the vehicle body 101 are driven by a cylinder to keep the clamping buckle 104 in an open state, ready to insert under the goods. After the forklift forks 103 are inserted under the goods, the cylinder drives the clamping buckle 104 to tighten, firmly clamping the goods on the forklift forks 103. After the goods are firmly clamped, the bundling mechanism 3 on both sides of the vehicle body 101 starts to work. The motor 204 is started to drive the lead screw 203 to rotate, causing the sliding seat 205 to descend along the lead screw 203. When the sliding seat 205 descends, the flexible tightening belt 206 detachably connected to a set of sliding seats 205 also descends and bypasses the goods. The other end of the flexible tightening belt 206 passes through the tightening seat 208 on another set of sliding seats 205. The motor in the tightening seat 208 drives the gear 209 to rotate, and the gear 209 meshes with the tooth grooves 207 on the inner wall of the flexible tightening belt 206, thereby tightening the flexible tightening belt 206. The strain gauge 213 provided at the joint of the flexible tightening belt 206 and the goods senses the tightening condition of the goods. When the strain gauge 213 senses that the goods have been firmly tightened, it sends an electrical signal to the control terminal in the vehicle body 101. After receiving the signal, the control terminal starts the cylinder 210 to push the locking block 211 to move to the designated position, firmly locking the flexible tightening belt 206. After the goods are firmly clamped and tightened, the driverless forklift 1 is carried through the Mecanum wheels 102. After reaching the destination, the forklift forks 103 are driven by the cylinder to open the clamping buckle 104 to release the goods. At the same time, the motor 204 of the bundling mechanism 3 rotates in reverse to drive the lead screw 203 to rotate, causing the sliding seat 205 to rise and loosen the flexible tightening belt 206.

[0040] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
