Description

Technical Field

[0001] The invention belongs to the technical field of steel production equipment, and in particular relates to a material head collecting device. Background Art

[0002] In the steel production process, the flying shear process will produce a large amount of scraps. The scrap collection device is used to collect the head and tail scraps generated after the flying shear shears the intermediate billet. Each flying shear is equipped with two scrap collection devices. When the scrap fills one of the scrap collection devices, the other scrap collection device is replaced. To replace the scrap collection device, the crane needs to lift the full scrap collection device out and place it on the transfer flat car. After it is transported to the vicinity of the transfer truck, the hanger pin is manually pulled out. The crane lifts the scrap collection device to the truck. The crane hook drops a certain distance to make the hanger detach from the fixed pin on the hopper. The crane lifts the hanger again. Due to the eccentric lifting, the bucket is flipped around the lower fixed pin to pour out the scraps in the bucket. The following problems exist during use: First, there may be an overload problem during the flipping, and the scraps are not dumped cleanly. At this time, manual assistance is required for cleaning, which poses certain safety hazards; second, the flipping operation requires a large flipping space, and it cannot be used normally in a narrow working space; third, the work efficiency of each use of the pin is low.

The driving assembly 8 includes a connecting rod 1 801 and a connecting rod 2 802. One end of the connecting rod 2 802 is hinged to the limiting pin 2 7, and the other end is hinged to one end of the connecting rod 1 801. The middle end of the connecting rod 1 801 is hinged to the mounting seat 1 803 on the cylinder 1. A driving column 80301 is fixedly arranged at one end of the connecting rod 1 801 away from the connecting rod 2 802. A driving plate 402 corresponding to the driving column 80301 is fixedly arranged at the upper end of the hook 4. The driving column 80301 is located between the driving plate 402 and the cylinder 1. A compression spring 5 is arranged between the end of the driving column 80301 away from the driving plate 402 and the cylinder 1, and the compression spring 5 plays a reset role.

[0050] The hook 4 is hinged to the mounting seat 2 104 on the cylinder 1 , and the hinged part of the hook 4 is located between the driving plate 402 and the limiting boss 401 .

[0051] A guide tube 10303 corresponding to the limiting hole 4 10302 is fixed on the limiting plate 103. The inner diameter of the guide tube 10303 matches the outer diameter of the limiting pin 2 7. The limiting pin 2 7 is installed on the inner side of the guide tube 10303. The guide tube 10303 plays a guiding role in the movement of the limiting pin 2 7.

[0052] A hinge plate 1 302 is fixedly arranged at one end of the bottom plate 3 away from the hook 4 , and a hinge plate 2 102 corresponding to the hinge plate 1 302 is fixedly arranged on the cylinder body 1 , and the hinge plate 1 302 is hinged to the hinge plate 2 102 via a hinge shaft.

[0053] The hook 4 is a structural member made of wear-resistant steel, and the wear-resistant steel hook 4 increases the service life of the device.

[0054] Working process:

[0055] During the implementation of this scheme, when the waste fills the inner side of the cylinder 1 of the device and the collection device needs to be replaced, the large hook under the crane in the workshop will lift the lifting rod 2 from the flying shear material pit and place it in the transfer flat car bucket, the small hook of the crane will lift the hanging hole 40301 of the hanging plate 403, and then the limit pin 6 will be manually pulled out, the crane will lift the material head collection device into the car bucket, the small hook of the crane will pull the bottom plate 3 of the hanging plate 403, and the limit boss 401 of the hook 4 will move away from the cylinder 1 to release the limit on the bottom plate 3.

[0056] The bottom plate 3 rotates along the hinge axis to open the opening at the lower end of the cylinder 1, and all the waste in the cylinder 1 falls into the bucket. The new material head collection device does not need to be lifted onto the transfer truck like the raw material head collection device, and it needs to be dropped onto the carriage and disengaged from the upper fixing pin before secondary lifting. It can also ensure that the head and tail waste in the hopper are completely dumped at one time. After the dumping is completed, the vehicle lifts the material head collection device onto the transfer flat car. When it falls, the bottom plane is used to drive the bottom plate 3 to rotate along the hinge axis. Under the guidance of the chamfered structure of the limiting boss 401, the limiting boss 401 of the hook 4 moves in the direction away from the cylinder 1. When the lower end surface of the limiting boss 401 is aligned with the upper end surface of the bottom plate 3, the limiting boss 401 of the hook 4 moves in the direction of the cylinder 1 to limit the bottom plate 3, and then the limiting pin 6 is inserted.

[0057] When the limiting boss 401 of the hook 4 moves toward the direction away from the cylinder 1, the driving plate 402 moves toward the direction of the cylinder 1, driving the driving rod to move toward the direction of the cylinder 1, and the end of the connecting rod 801 away from the driving rod moves toward the direction away from the cylinder 1. The end of the connecting rod 802 away from the limiting pin 27 moves toward the direction away from the cylinder 1, driving the limiting pin 27 to move out of the limiting hole 30302. The rotation of the hook 4 drives the limiting pin 27 to move, which plays a double limiting role and improves the stability during use.

[0058] In some embodiments, the limit pin 1 6 , the limit pin 2 7 , and the hook 4 are used simultaneously to limit the bottom plate 3 .

[0059] In some embodiments, the limiting pin 2 7 and the hook 4 are used to limit the bottom plate 3 , and the limiting pin 2 7 can be contacted without manually pulling out the limiting pin 2 7 , thereby improving work efficiency.

[0060] Compared with the traditional flip-type dumping, by setting a hinged base plate 3 and hook 4, the material head can be dumped without flipping, which improves work efficiency. The dumping process does not require flipping, which is suitable for narrower working spaces. The setting of the hook 4 facilitates the buckling of the base plate 3, thereby improving work efficiency.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents.
