Description

Technical Field

[0001] The invention relates to the technical field of forklift attachments, in particular to an omnidirectional forklift attachment. Background Art

[0002] In modern industrial handling operations, forklifts are widely used for loading, unloading and transporting materials. However, the clamping structure of traditional forklift attachments generally has some technical defects and cannot meet the diverse handling needs. Traditional forklift attachments usually use fixed or semi-fixed clamping mechanisms, which have relatively simple clamping structures and poor adaptability, especially when handling materials of different specifications and shapes, which have great limitations.

[0003] Existing forklift attachments mainly use mechanical clamps or forks to clamp or transport materials. These designs can easily cause the materials to shift or slip when handling large or irregularly shaped materials, affecting the safety and reliability of handling. At the same time, traditional clamping mechanisms lack flexible adjustment functions and are usually only applicable to materials of specific sizes or shapes, making it difficult to meet diverse operating requirements. When encountering materials with large size changes, attachments need to be replaced frequently, reducing operating efficiency.

[0004] In addition, the clamping force of traditional attachments is mostly fixed, and there is a lack of real-time monitoring and adjustment of the clamping force, which can easily lead to excessive or insufficient clamping force. Excessive clamping force may cause damage to the material, while insufficient clamping force may cause the material to fall off during handling, increasing the risk of material damage and safety hazards. Traditional attachments also usually lack the function of flipping materials, which is especially inconvenient to operate when goods need to be transported in multiple directions, making it difficult to achieve flexible handling requirements. Summary of the invention

[0005] The present invention aims to solve one of the technical problems existing in the prior art or related technology.

[0006] To this end, the technical solution adopted by the present invention is: an omnidirectional forklift attachment, comprising: an attachment plate, a drive frame, a chuck rod and a plug rod, wherein a swivel seat is rotatably installed on the inner side of the attachment plate, an inner gear ring is fixedly installed on the inner side of the attachment plate, a drive motor for transmission engagement with the surface of the inner gear ring is fixedly installed on the inner side of the swivel seat, and a connecting ear for connecting to an omnidirectional forklift is fixedly installed on the surface of the attachment plate.

[0007] Through this design, the attachment can clamp, transport and flip materials, which is particularly suitable for handling materials of different specifications, ensuring the stability and safety of materials during the handling process.

[0008] In a possible embodiment, there are two groups of drive frames and they are arranged parallel to each other and fixed on the surface of the swivel seat. The drive frame includes a fixed ear frame, a screw rod assembly, an adjusting connecting rod and a driving rod. The screw rod assembly is fixedly installed on the surface of the fixed ear frame to drive the chuck rod to move up and down relative to the surface of the plug rod. The driving rod is movably installed on the surface of the fixed ear frame. One end of the plug rod is provided with a rotating sleeve clamp rotatably installed on the surface of the fixed ear frame. The surface of the rotating sleeve clamp is provided with a crank ear. The other end of the driving rod is movably connected to the surface of the crank ear. The output end of the screw rod assembly is provided with a screw sleeve slide. A rotating shaft pin rotatably sleeved on the surface of the screw sleeve slide is fixedly installed on the surface of the chuck rod. The surface of the rotating shaft pin is fixedly connected with a crank rod. The surface of the fixed ear frame is provided with an adjusting slide, and an adjusting pin is slidably installed on the inner side of the adjusting slide. The two ends of the adjusting connecting rod are respectively rotatably connected to the surfaces of the crank rod and the adjusting pin.

[0009] Through this design, the parallel arrangement of the two sets of drive frames can enable the attachment to stably clamp the material, and through the lifting and deflection movement of the screw assembly and the drive rod, flexible operation of the material can be achieved to adapt to different handling needs.

[0010] In a possible implementation manner, the drive motor is an outer rotor motor structure, and a transmission gear ring that is transmission-engaged with the inner side of an inner gear ring is sleeved on the outer periphery of the drive motor.

[0011] By adopting an outer rotor motor structure, the attachment can achieve efficient rotation transmission, so that materials can be flexibly turned over during transportation and adapt to complex working environments.

[0012] In a possible embodiment, the screw assembly includes a screw motor and a screw rotatably mounted on the surface of the fixed ear bracket. The inner side of the screw sleeve slide is provided with a threaded sleeve that is sleeved on the screw surface. The screw motor drives the screw sleeve slide to rise and fall and slide on the screw surface.

[0013] This structure can accurately control the lifting and lowering movement of the attachment, ensuring the stability of the material position during transportation and avoiding material damage caused by height differences.

[0014] In a possible implementation, the connection end of the adjusting connecting rod and the crank rod deviates from the axis of the rotating shaft pin, and the surface of the adjusting pin is provided with a locking member for connecting with the surface of the adjusting slideway to lock the position of the adjusting pin on the surface of the adjusting slideway.

[0015] Through this eccentric design and the fixing structure of the locking piece, the clamping force of the attachment on the material can be enhanced, while ensuring the stability of the attachment position during operation.

[0016] In a possible implementation manner, the chuck rod and the plug rod are arranged parallel to each other, and the chuck rod and the plug rod and the screw rod of the screw rod assembly are located in the same vertical plane.

[0017] This parallel arrangement can ensure the balance of the attachment when clamping and transporting materials, and prevent the materials from sliding due to tilting during transportation.

[0018] In a possible implementation manner, a receiving groove is provided on the surface of the plug rod, and the receiving groove is adapted to the shape and specification of the clamp rod, and a pressure pad for improving clamping friction is provided on the bottom surface of the clamp rod.

[0019] By providing matching structures on the plug rod and the clamp rod and increasing the clamping friction, the material can be effectively prevented from sliding during the clamping process, ensuring the secure handling of the material.

[0020] In a possible embodiment, a control board is fixedly installed on the inner side of the swivel seat, and pressure sensors are embedded on the surfaces of the plug rod and the chuck rod for monitoring the clamping force, and the output end of the pressure sensor is electrically connected to the input end of the control board. The control board is used to monitor the pressure and provide real-time feedback to control the clamping force of the chuck rod and the plug rod.

[0021] By setting up pressure sensors and control panels, intelligent monitoring and automatic adjustment of clamping force can be achieved to avoid damage to materials or material slippage due to over-clamping or under-clamping, further improving the safety of handling and the accuracy of operation.

[0022] In a possible implementation, an electric slip ring for electrical connection of the control panel is provided on the inner side of the connecting ear and the surface of the swivel seat, so as to maintain the electrical connection between the swivel seat, the drive rod and the screw assembly and the omnidirectional forklift control system during the rotation of the swivel seat.

[0023] The setting of the electric slip ring can ensure that the attachment maintains a stable electrical connection during rotation, avoid cable entanglement or disconnection problems, and ensure continuous and stable operation of the system.

[0024] The beneficial effects achieved by the present invention are:

[0025] 1. In the present invention, by the fixed connection between the attachment plate and the forklift, combined with the coordinated work of the swivel seat, the drive frame, the clamp rod and the plug rod, the attachment can realize the clamping, consignment and flipping of materials during the material handling process, which is particularly suitable for the handling needs of materials of diversified specifications.

[0026] 2. In the present invention, the clamping control of the chuck rod and the plug rod is performed through the deflection movement of the driving rod and the lifting movement of the screw assembly, which can stably support and clamp the material, prevent the material from falling off, and improve the reliability and safety of transportation.

[0027] 3. In the present invention, through the adjustable design of the adjustment slide and the adjustment pin, the user can flexibly adjust according to the material specifications, adapt to materials of different sizes, and quickly and conveniently adjust the operating status of the accessories, thereby enhancing the adaptability of the system. Pressure sensors are embedded and installed on the surface of the chuck rod and the plug rod. Combined with the feedback control system of the control panel, the clamping force can be monitored in real time to prevent the clamping from being too loose or too tight, thereby ensuring the safe handling of materials.

[0039] To make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in combination with specific implementations and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0040] It is to be understood that these descriptions are exemplary only and are not intended to limit the scope of the invention.

[0041] The following is combined with Figure 1-Figure 7 An omnidirectional forklift attachment provided by some embodiments of the present invention is described. Example

[0042] The present invention provides an omnidirectional forklift attachment, comprising an attachment plate 100, a drive frame 200, a chuck rod 300 and a plug rod 400. A rotating seat 120 is rotatably mounted on the inner side of the attachment plate 100, and an inner gear ring 140 is fixedly mounted on the inner side of the attachment plate 100. On this basis, a driving motor 130 for driving engagement with the surface of the inner gear ring 140 is also fixedly mounted on the inner side of the rotating seat 120. The rotation control of the attachment can be realized through the action of the driving motor 130. A connecting ear 110 for connecting to an omnidirectional forklift is fixedly mounted on the surface of the attachment plate 100.

[0043] In this embodiment, the number of the drive racks 200 is two groups, and the two groups of drive racks 200 are arranged parallel to each other and fixed on the surface of the rotating seat 120. Each group of drive racks 200 includes a fixed ear rack 210, a screw assembly 220, an adjustment connecting rod 230 and a driving rod 240. The screw assembly 220 is fixedly mounted on the surface of the fixed ear rack 210, and is used to drive the clamp rod 300 to move up and down relative to the surface of the plug rod 400. The driving rod 240 is movably mounted on the surface of the fixed ear rack 210, and the plug rod 400 is driven by the movement of the driving rod 240. At the same time, one end of the plug rod 400 is rotatably mounted on the rotating sleeve clamp 410 on the surface of the fixed ear rack 210, and a crank ear 411 is provided on the surface of the rotating sleeve clamp 410. The other end of the driving rod 240 is movably connected to the surface of the crank ear 411, so that the overall drive and control are realized.

[0044] Furthermore, the output end of the screw assembly 220 is provided with a screw sleeve slide 221, and the surface of the chuck rod 300 is fixedly mounted with a rotating shaft pin 310 that is rotatably sleeved on the surface of the screw sleeve slide 221. Through the rotational connection of the rotating shaft pin 310, the chuck rod 300 can be deflected relative to the screw sleeve slide 221, thereby achieving the clamping and adjustment of the material. In addition, the surface of the rotating shaft pin 310 is also fixedly connected with a crank rod 231, and the surface of the adjusting connecting rod 230 is rotatably connected to the crank rod 231 and the adjusting pin 212, thereby achieving more precise clamping and control.

[0045] In this embodiment, the clamp rod 300 and the plug rod 400 are arranged parallel to each other and are located in the same vertical plane as the screw of the screw assembly 220. The advantage of this design is that it can ensure that the material remains balanced during transportation and prevent the material from tilting or deflecting during lifting or clamping. Example

[0046] In another embodiment of the present invention, the structures of the chuck rod 300 and the plug rod 400 are further optimized. In this embodiment, a pressure pad is also provided on the surface of the chuck rod 300 to increase the friction when clamping the material, ensuring that the material will not slip due to insufficient clamping force during the handling process. At the same time, a storage groove 401 is provided on the surface of the plug rod 400, and the shape and specification of the storage groove 401 are compatible with the chuck rod 300. Through this design, when clamping larger or special-shaped materials, the clamping operation can be performed more stably.

[0047] In this embodiment, a control board is fixedly installed on the inner side of the rotating seat 120, and pressure sensors are embedded and installed on the surfaces of the plug rod 400 and the clamp rod 300. Through real-time monitoring by these sensors, the system can automatically adjust the clamping force according to the size and weight of the material to prevent the clamping from being too loose or too tight, thereby improving the safety of the handling process. In addition, the output end of the pressure sensor is electrically connected to the control board, and the control board is used for real-time feedback control based on the sensor data, further ensuring the intelligent operation of the system.

[0048] In order to ensure that the electrical system can work normally during the rotation of the attachment, an electric slip ring is also provided on the inner side of the connecting ear 110 and the surface of the swivel seat 120, which is used to maintain the electrical connection between the drive rod 240 and the screw assembly 220 and the omnidirectional forklift control system when the swivel seat 120 rotates, thereby ensuring continuous power supply and stable operation of the entire attachment system at different angles.

[0049] In summary, through the optimized design in this embodiment, the present invention realizes multi-directional, high-precision clamping and handling operations of materials, which is particularly suitable for the handling needs of materials of various specifications, while improving the automation level and operational stability of the system.

[0050] Extended description

[0051] In both embodiments, the present invention achieves rotation transmission between the swivel seat 120 and the attachment plate 100 by meshing the outer rotor motor structure of the driving motor 130 with the inner gear ring of the inner gear ring 140, thereby ensuring the rotation ability of the attachment. In addition, by adjusting the connection end of the connecting rod 230 and the crank rod 231 to deviate from the axis of the rotating shaft pin 310, combined with the locking function of the adjusting pin 212, the flexibility of the clamping control is further improved.

[0052] The working principle and use process of the present invention:

[0053] When the forklift attachment is used, the forklift attachment is fixed to the driving end of the omnidirectional forklift through the connecting ear 110 on the surface of the attachment plate 100, and the forklift drives the entire attachment plate 100 up and down, connects the control circuit of the swivel seat 120, the driving rod 240 and the screw assembly 220, and adjusts the initial position of the adjustment pin 212 according to the specifications of the material to be transported and fixes it;

[0054] During the material handling process, the driving rod 240 drives the plug rod 400 to deflect at the sleeve point of the rotating sleeve clamp 410, and the material is clamped and unloaded by the opposite deflection movement of the plug rod 400 on the surface of the fixed ear brackets 210 on both sides; or after the two parallel plug rods 400 are used to scoop up and support the material, the screw sleeve slide 221 is controlled to move up and down under the drive of the screw rod assembly 220, and the positioning adjustment pin 212 and one end of the adjustment connecting rod 230 are connected to the shaft pin 310 to realize the deflection movement of the chuck rod 300 under the lifting effect of the screw sleeve slide 221, and the chuck rod 300 deflects with the shaft pin 310 as the axis, and the chuck rod 300 clamps and controls the scooped material on the top surface of the plug rod 400 to prevent the material from falling off the surface of the plug rod 400;

[0055] Furthermore, whether the plug rod 400 is in a clamping working state for both sides of the material, or the chuck rod 300 and the plug rod 400 are in a clamping working state for the material together, the driving effect of the motor 130 inside the swivel seat 120 can be used to cause the material clamped by the chuck rod 300 and the plug rod 400 to perform a flipping motion, thereby realizing material handling and flipping.

In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example.
