DETAILED DESCRIPTION

[0013] 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.

[0014] See also Figure 1The present application provides a technical solution: a ton bag grabbing device, including a claw device 1, 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, the claw mounting frame 1.3 is connected to the claw transmission group 1.2, and the claw group 1.1 is connected to the claw transmission group 1.2 through a strip plate group 2.

[0015] 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.

[0016] 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.

[0017] The claw transmission group 1.2 is responsible for driving the claw group 1.1 to open and close, thereby realizing the grabbing and releasing of the ton bag.

[0018] The claw mounting frame 1.3 provides mounting positions for the various components of the claw device 1, and provides stable support and fixing effects; and then integrates the claw group 1.1, the claw transmission group 1.2 and other auxiliary components together to form a complete functional unit.

[0019] The claw transmission group 1.2 includes a claw driving member 1.21, a driving gear 1.22 and a transmission gear 1.23. The end gear of the claw driving member 1.21 is engaged with the driving gear 1.22 arranged on the left side, the 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 driving gear 1.22 arranged on the right side.

[0020] The jaw drive 1.21 is a power source, providing the energy required to open and close the jaw assembly 1.1. The jaw drive 1.21 can accurately control the output torque or thrust according to the control signal to ensure that the jaws move smoothly and powerfully.

[0021] The gear transmission system composed of the driving 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 due to uneven force.

[0022] The outer side surface of the transmission shaft sleeved with the driving gear 1.22 is sleeved with a strip plate set 2.

[0023] 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.

[0024] Furthermore, it also includes a clamping claw adjustment group 3 and an installation connection frame 4, and the clamping claw adjustment group 3 is arranged in the installation connection frame 4.

[0025] 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.

[0026] Furthermore, the claw adjustment group 3 is composed 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.

[0027] The claw driving gear 3.1 is the power input end of the lifting group, 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.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] 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 driving gear 1.22 is connected is connected to 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.

[0032] The first strip plate 2.1 is sleeved on the outside of the transmission shaft of the 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.

[0033] When in use: according to the height of the ton bag, the claw device 1 is adjusted to a suitable grabbing height through the claw adjustment group 3; a control command is issued, and the claw driving gear 3.1 drives the rack 3.2 to move under the action of the external driving device, thereby driving the claw device 1 to move to a suitable position, and starting the claw driving member 1.21; the gear transmission system composed of the driving gear 1.22 and the transmission gear 1.23 starts to operate, converting the rotational movement 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 external driving device, the ton bag is lifted.

[0034] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
