[0029] The plurality of gas bags 15 are distributed on the outer wall of the clamping arm 9.
[0030] Specifically, the air pump 13 absorbs the air outside and transports it to the control assembly through the gas conveying pipe 14, then the motor rotates to drive the partition cylinder 19 to rotate, when the gas outlet hole one 17 and the gas outlet hole two 20 are aligned, the air in the external shell 16 is transported to the gas bag 15 through the partition pipe 21, and the gas bag 15 expands accordingly; the plurality of gas bags 15 on the outer wall of the clamp expand according to the specific circumstances of the material to fully adhere to the material.
[0031] The material of the lifting chain 4 and the adjusting chain 5 is high-strength alloy steel, and the material of the anti-unhooking device 6 is alloy structural steel.
[0032] The material of the crossbeam 8 is carbon structural steel, and the material of the clamping arm 9 is high-strength alloy steel.
[0033] Specifically, important components are made of high-strength materials such as high-strength alloy steel or carbon structural steel to meet the strength requirements of actual use.
[0034] Working principle: In the preparation stage of hoisting operation, the operator first determines the relative position of the material and the gantry 1, and then drives the gantry 1 to the top of the material through the external driving device. Then, the fixed frame 2 is slid along the outer wall of the gantry 1, and the adjusting mechanism is adjusted to the appropriate horizontal position. Subsequently, by controlling the rotation of the sprocket 3, the extension and retraction of the lifting chain 4 and the adjusting chain 5 are adjusted. When the material needs to be lifted or lowered, the sprocket 3 is rotated to operate the lifting chain 4, and the anti-unhooking device 6 connected to one end of the lifting chain 4 will rise or fall accordingly, thereby driving the whole line hoist clamp to approach or move away from the material.
[0035] In the process of clamping the material, the hydraulic cylinder 10 in the line hoist clamp starts to work, and the output end of the hydraulic cylinder 10 pushes the pressure plate 11. Since the two ends of the pressure plate 11 are fixedly connected to the limiting plate 12 on the outer wall of the clamping arm 9, the movement of the pressure plate 11 will drive the clamping arm 9 to tighten until the material is tightly clamped. In this process, the limiting plate 12 plays a role in limiting the movement range of the clamping arm 9, ensuring the accuracy and stability of the clamping action, preventing the clamping arm 9 from being excessively opened or closed, and avoiding unnecessary collision damage to the material; after clamping the material, the air pump 13 is started, the input end of the air pump 13 inhales air from the outside, and after compression, the air is transmitted to the control assembly through the air conveying pipe 14. The motor 18 in the control assembly drives the split seal cylinder 19 to rotate. When the air outlet hole two 20 on the split seal cylinder 19 is aligned with the air outlet hole one 17 on the outer wall of the external shell 16, the air will enter the split seal pipe 21 through the air outlet hole one 17, and finally enter the air bag 15 on the outer surface of the clamping arm 9, causing the air bag 15 to expand. In the hoisting process, if the material collides slightly with the surrounding equipment or other objects, the air bag 15 can play a buffering role, reducing the impact force caused by the collision on the material, effectively protecting the material with soft texture or a surface prone to damage.
[0036] During the hoisting process, if it is necessary to adjust the posture and angle of the material, the operator can adjust the angle of the whole line hoist clamp by retracting or extending the adjusting chain 5 at both ends of the crossbeam 8. For example, when the adjusting chain 5 on one side is tightened, the fixed frame 2 will tilt to that side, and the line hoist clamp and the clamped material will also tilt accordingly, achieving fine adjustment of the posture and angle of the material to meet the requirements of the material placement position during gantry milling machine processing.
[0037] When the hoisting is finished and the material needs to be put down, the hydraulic cylinder 10 is operated reversely to make its output end retract, drive the pressure plate 11 to move reversely, make the clamping arm 9 open, and place the material to the designated position, then the air pump 13 stops working, the gas in the air bag 15 is discharged through the control assembly, and the next hoisting operation is prepared.
[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for those skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
