DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0018] See also Figure 1 The present application provides a technical solution: a lifting and adjustable ton bag automatic grabbing device, comprising a claw device 1, an adjusting rotating seat for adjusting the angle of the claw device 1, and a lifting and adjusting group 8 for adjusting the height of the claw device 1.
[0019] The adjusting rotating seat provides the claw device 1 with a degree of rotational freedom, allowing the claw device 1 to rotate around a certain axis (such as a vertical axis) within a certain range; the adjusting rotating seat is used to adjust the angle of the ton bag in the hoisting state to facilitate subsequent transportation.
[0020] The lifting adjustment group 8 is composed of a lifting bracket 8.1, a lifting drive member 8.2, a lead screw 8.3 and a lifting guide rod 8.4. The lifting bracket 8.1 is provided with a lifting drive member 8.2, and the output end of the lifting drive member 8.2 is connected to the lead screw 8.3, and the lead screw 8.3 is sleeved with the claw device 1. The lifting guide rod 8.4 is connected to the upper surface of the mounting connection frame 4 and is sleeved with the guide sleeve in the lifting bracket 8.1.
[0021] The lifting bracket 8.1 is the basic structure of the claw adjustment group 38, and the lifting bracket 8.1 provides support and stability for the entire device; the lifting bracket 8.1 is provided with mounting holes, fixing seats and other structures for installing the lifting drive 8.2, the lead screw 8.8 and other components.
[0022] According to the command issued by the control system, the lifting drive 8.2 generates thrust or pulling force to push or pull the claw device 1 to lift. The lifting drive 8.2 has good linear output characteristics, sufficient push and pull force and speed control capabilities to ensure smooth and accurate lifting action.
[0023] The lead screw 8.8 in the claw adjustment group 38 converts the rotational motion of the lifting drive 8.2 into the linear lifting motion of the claw device 1. The output end of the lifting drive 8.2 is connected to the lead screw 8.8. When the lifting drive 8.2 is running, the lead screw 8.8 rotates accordingly, and through the action of the thread pair, drives the claw device 1 connected thereto to move up and down. The lead screw 8.8 has high transmission accuracy and self-locking performance, which is conducive to improving the positioning accuracy and safety of the equipment.
[0024] The lifting guide rod 8.4 is used in conjunction with the lead screw 8.8 to provide radial guidance for the lifting movement of the claw device 1, ensuring that it moves smoothly along a straight line to prevent deflection or shaking. One end of the lifting guide rod 8.4 is connected to the upper surface of the mounting connection frame 4, and the other end is sleeved with the guide sleeve in the lifting bracket 8.1. In this way, the lifting guide rod 8.4 plays a role in constraining the lateral freedom of the claw device 1 during the lifting process, thereby enhancing the stability of the equipment operation.
[0025] The adjusting rotating seat comprises a rotating disk 6 and a steering motor 7 , and a driving gear outside the rotating disk 6 is meshed with an output gear of the steering motor 7 which is arranged on the mounting connection frame 4 and drives the rotating disk to rotate.
[0026] The turntable 6 is the main part of the adjustment rotating seat, which is connected to the mounting connection frame 4 to ensure that it can rotate freely around a certain axis. The outer periphery of the turntable is provided with driving teeth, which mesh with the output gears of the steering motor 7 to form a gear transmission mechanism; the turntable 6 needs to have sufficient rigidity and load-bearing capacity to bear the weight of the claw device 1 and the ton bag, and maintain structural stability during the rotation process.
[0027] The steering motor 7 receives the control system command, drives the output gear to rotate, and then drives the turntable 6 and the claw device 1 connected thereto to adjust the angle. The steering motor 7 should have good speed regulation performance, torque output capacity and response speed to ensure accurate and smooth rotation.
[0028] Furthermore, the claw device 1 is mainly composed of a claw group 1.1, a claw transmission group 1.2 and a claw mounting frame 1.3, and the claw mounting frame 1.3 is connected to the claw transmission group 1.2.
[0029] The clamping claw device 1 realizes stable and effective grasping of the ton bag. The clamping and releasing tasks of the ton bag are completed through the mutual cooperation between the clamping claw group 1.1, the clamping claw transmission group 1.2 and the clamping claw mounting frame 1.3.
[0030] The claw group 1.1 is the part that directly contacts the ton bag assembly. The claw group 1.1 is usually composed of symmetrically arranged mechanical claws. The claws can open and close independently or synchronously. When closed, they tightly clamp the edges of the ton bag assembly to ensure that the bag will not slip or loosen during transportation. The claw material is usually made of wear-resistant and impact-resistant metal materials, and the surface may be anti-slip treated to enhance the reliability of grasping.
[0031] The claw transmission group 1.2 includes a claw driving member 1.21, a power driving gear 1.22 and a transmission gear 1.23. The end gear of the claw driving member 1.21 is engaged with the power driving gear 1.22 arranged on the left side, the power driving gear 1.22 on the left side is meshed with the transmission gear 1.23, and the transmission gear 1.23 is meshed with the power driving gear 1.22 arranged on the right side.
[0032] The jaw driving member 1.21 is a power source, providing the energy required to open and close the jaw assembly 1.1; the jaw driving member 1.21 can accurately control the output torque or thrust according to the control signal to ensure that the jaws move smoothly and powerfully.
[0033] The gear transmission system composed of the power drive gear 1.22 and the transmission gear 1.23 converts the rotational motion generated by the claw driving member 1.21 into the rotational motion required by the claw group 1.1. Through the meshing and transmission ratio setting between the gears, it can ensure that all the claws open and close synchronously and evenly, avoiding unstable grasping caused by uneven force.
[0034] Furthermore, it also includes a claw adjustment group 3, which consists of a claw driving gear 3.1, a rack 3.2, and a support plate 3.3 connected to the claw device 1, the rack 3.2 is located on one side of the support plate 3.3, and the claw driving gear 3.1 is meshed with the rack 3.2.
[0035] The claw adjustment group 3 ensures that the claw device 1 can be accurately adjusted in height within a certain range according to actual operation needs, so that the traction rope connected to the ton bag is in a hoisting state after being stressed, thereby improving the practicality of hoisting.
[0036] The claw driving gear 3.1 is the power input end of the claw adjustment group 3, and is usually driven to rotate by an electric, hydraulic or pneumatic driving source through a transmission mechanism; the transmission principle of the claw driving gear 3.1 and the rack 3.2 is converted into a linear reciprocating motion of the rack 3.2, thereby realizing the height change of the claw device 1.
[0037] The rack 3.2 is fixed on one side of the support plate 3.3, and its length matches the travel range, ensuring that the claw device 1 can be lifted or lowered within the required working height range.
[0038] The support plate 3.3 serves as a bridge connecting the rack 3.2 and the claw device 1. On the one hand, it provides an installation and support platform for the rack 3.2 to ensure the stability and straightness of the rack 3.2 during the transmission process; on the other hand, the support plate 3.3 is connected to the claw device 1 by bolt connection, welding, hinge, etc., to transmit the linear motion of the rack 3.2 to the claw device 1 to realize its lifting action.
[0039] Furthermore, guide shafts 5 are arranged on both sides of the upper end of the clamping claw mounting frame 1.3, and the guide shafts 5 pass through the mounting connection frame 4.
[0040] Furthermore, a strip plate set 2 is sleeved on the outer side surface of the transmission shaft sleeved with the power driving gear 1.22.
[0041] The strip plate group 2 serves as an intermediary structure connecting the claw group 1.1 and the claw transmission group 1.2, and the strip plate group 2 ensures effective transmission of power.
[0042] Furthermore, the strip plate group 2 is composed of a first strip plate 2.1 and a second strip plate 2.2, the outer side surface of the transmission shaft to which the power driving gear 1.22 is sleeved is sleeved with the first strip plate 2.1, and the claw group 1.1 is connected to the second strip plate 2.2 arranged on the claw mounting frame 1.3.
[0043] The first strip plate 2.1 is sleeved on the outside of the transmission shaft of the power driving gear 1.22, and the second strip plate 2.2 is fixed on the claw mounting frame 1.3, and rotates with the rotation of the gear, transmitting the power of the claw transmission group 1.2 to the claw, thereby controlling the opening and closing of the claw, improving the structural compactness and transmission efficiency of the equipment, and ensuring the synchronization and stability of the claw action.
[0044] When in use: adjust the claw device 1 to a suitable grasping height through the claw adjustment group 3; issue a control command, and the gear 3.1 drives the rack 3.2 to move under the action of the external drive device, thereby driving the claw device 1 to move to a suitable position, start the claw driving member 1.21, and the gear transmission system composed of the power driving gear 1.22 and the transmission gear 1.23 starts to operate, converting the rotational motion of the driving member into the opening and closing action required by the claw group 1.1; the first strip plate 2.1 in the strip plate group 2 rotates with the transmission shaft, and transmits power to the claw group 1.1 through the connection with the second strip plate 2.2; all the claws open synchronously and evenly, grab the rope wrapped around the ton bag, and ensure that the claws are accurately positioned. At this time, under the action of the lifting and adjusting group 8, the claw device 1 is adjusted to a suitable grasping height through the lifting and adjusting group 8. During this process, the lifting drive member 8.2 operates according to the instructions issued by the control system. When the lifting drive member 8.2 is in operation, the lead screw 8.8 rotates accordingly, and through the action of the threaded pair, drives the claw device 1 connected thereto to move; the lifting guide rod 8.4 is used in conjunction with the lead screw 8.8 to provide radial guidance for the lifting movement of the claw device 1, ensuring that it moves smoothly along a straight line to prevent deflection or shaking.
[0045] If the lifting angle of the ton bag needs to be adjusted, send a command to the steering motor 7 through the control system to drive the turntable 6 to rotate and adjust the claw device 1 to the required angle. Observe the positioning mark or sensor feedback on the turntable 6 to ensure that the angle is adjusted accurately and adjust the ton bag to the appropriate position to meet the needs of later transportation.
