Description

Technical Field

[0001] The utility model relates to the technical field of casting, in particular to an integral shroud removal tool. Background Art

[0002] The ladle shroud switching mechanism allows switching between a conventional ladle shroud and an integrated shroud. For conventional ladle shrouds, operators must manually install them onto the ladle outlet using a robotic arm for protective pouring. The integrated shroud integrates the ladle outlet and shroud, allowing operators to automatically install them using a robot controlled by the automation system panel.

[0003] After the integral shroud in the shroud switching mechanism of the ladle is used, if for some reason (such as the robot's visual scanning system cannot recognize it) the robot cannot remove it from the mechanism, then the operator will cut it off from the neck in the pouring area. Since the operation of rotating and removing the shroud cannot be performed in the pouring area, the ladle needs to be transferred to the preparation area to remove the remaining shroud that has been cut off from the mechanism. However, even if the shroud is manually removed in the preparation area, due to the lack of special tools, the lifting and removal operations in the preparation area pose safety risks and are time-consuming and labor-intensive.

[0004] Therefore, it is urgent to design an integral shroud removal tool to solve the above problems. Utility Model Content

[0048] This embodiment provides an integrated shroud removal tool 100, which can remove the shroud 200 more conveniently and quickly, reducing operational risks and saving time and effort. Figure 1 As shown, the integral shroud removal tool 100 needs to be used with the aid of a hoisting tool 400. When the ladle is transferred to the preparation area, the hoisting tool 400 hoists the integral shroud removal tool 100 to a position substantially at the same height as the shroud 200, and then the staff installs the integral shroud removal tool 100 onto the shroud 200. Specifically, Figure 2 and Figure 3 As shown, the integral long water nozzle removal tool 100 includes a collar 10, a handpiece 30 and at least two fixing pins 20. The at least two fixing pins 20 are arranged at intervals along the circumference of the collar 10 and are axially passed through the collar 10. The collar 10 is used to be sleeved on the outside of the long water nozzle 200 so that the at least two fixing pins 20 are inserted one by one into the pin holes 310 formed outside the long water nozzle 200; the handpiece 30 is connected to the circumferential side of the collar 10, and the handpiece 30 is used to drive the collar 10 to rotate.

[0049] When using the above-mentioned integral long nozzle removal tool 100, the handpiece 30 is held and the ring 10 is inserted into the outside of the long nozzle 200. At this time, at least two fixing pins 20 are inserted into the pin holes 310 formed outside the long nozzle 200. The handpiece 30 is rotated to rotate the ring 10. Driven by the fixing pins 20, the long nozzle 200 rotates accordingly. After rotating to a certain angle, the long nozzle 200 can be axially separated from the ladle. When the long nozzle 200 is removed, since the ring 10 is on the outer periphery of the long nozzle 200, the sling carries the ring 10 to transfer the long nozzle 200 away. In this process, the removal of the long nozzle 200 is more convenient and quick, saving time and effort, and reducing the operator's operating risks.

[0050] It should be noted that a hoop 300 is provided around the exterior of the shroud 200. The hoop 300 and the outer periphery of the shroud 200 form at least two pin holes 310. In this embodiment, four pin holes 310 and four fixing pins 20 are provided. In other embodiments, the number of pin holes 310 and fixing pins 20 can also be two, three, five, or more, and this is not limited here.

[0051] Optionally, two handpieces 30 are provided at intervals in the circumferential direction of the collar 10 , and the two handpieces 30 facilitate simultaneous operation by the operator with both hands.

[0052] like Figure 3As shown, the size of the pin hole 310 is larger than that of the fixing pin 20, which allows the operator to have a larger tolerance when inserting the fixing pin 20 into the pin hole 310. However, after the fixing pin 20 is fully inserted into the corresponding pin hole 310, for example, when the collar 10 is rotated clockwise, the fixing pin 20 abuts against the right side of the inner wall of the pin hole 310. During operation, if the operator relaxes his force slightly or makes an error in operation, causing the collar 10 to rotate counterclockwise or tend to rotate counterclockwise, the fixing pin 20 will be separated from the inner wall of the pin hole 310, and the collar 10 is at risk of being separated from the long nozzle 200.

[0053] In order to solve the above problems, Figure 2 and Figure 3 As shown, the integrated shroud removal tool 100 provided in this embodiment further includes a locking pin 40 , which is detachably plugged into the collar 10 to clamp the side wall of one of the pin holes 310 between the locking pin 40 and the corresponding fixing pin 20 .

[0054] Through the above arrangement, the inner side of the side wall of the hoop member 300 is abutted by a fixing pin 20. At this position, the outer side wall of the hoop member 300 is abutted by the locking pin 40. At this location, the side wall of the hoop member 300 is clamped. Regardless of whether the collar 10 rotates clockwise or counterclockwise, it will not detach from the outside of the long water outlet 200.

[0055] Alternatively, as Figure 2 As shown, the lock pin 40 includes a lock pin body 41 and a first engaging member 42. The lock pin body 41 can be inserted into the collar 10. The first engaging member 42 is arranged at an angle to the lock pin body 41. The collar 10 is provided with a second engaging member 12 axially protruding therefrom. The second engaging member 12 defines a slot 121. The lock pin body 41 can be rotated to engage or disengage the first engaging member 42 in the slot 121. With this arrangement, the lock pin body 41 is inserted into the corresponding through-hole on the corresponding collar 10. Once in place, the lock pin body 41 is rotated, and the first engaging member 42 engages the slot 121, thereby securing the position of the lock pin 40.

[0056] Optionally, the second clamping member 12 is rectangular, and the clamping slot 121 is open on a side away from the center of the collar 10 and on a side facing the first clamping member 42. This arrangement prevents the first clamping member 42 from falling out of the clamping slot 121 under the action of gravity when it falls into the clamping slot 121, thereby ensuring the stability of the clamping connection between the two.

[0057] It should be noted that the locking pin 40 is positioned so as to be substantially in the upper half of the shroud 200 during rotation, so that the closed end of the slot 121 can block the rotation tendency of the first engaging member 42 under gravity.

[0058] Alternatively, as Figure 2As shown, the lock pin body 41 includes a first plug-in portion 411 and a rotating portion 412. The first plug-in portion 411 can be plugged into the collar 10. The first clamping member 42 is connected to the first plug-in portion 411 at an angle. The rotating portion 412 is arranged at an angle to the first plug-in portion 411. This arrangement allows the operator to more conveniently hold the rotating portion 412 and rotate it, thereby driving the first plug-in portion 411 to rotate. For example, the first clamping member 42 and the first plug-in portion 411 are perpendicular, and the rotating portion 412 is perpendicular to the first plug-in portion 411.

[0059] Optionally, in order to prevent the locking pin 40 from being lost, the locking pin 40 and the collar 10 are connected by a chain.

[0060] Alternatively, as Figure 2 As shown, the fixing pin 20 includes a second plug-in portion 21, a limiting portion 22, and a retaining spring 23. The second plug-in portion 21 can be inserted into the collar 10; the limiting portion 22 is connected to one end of the second plug-in portion 21 and can abut the end surface of the collar 10. The second plug-in portion 21 defines a mounting groove 211; the retaining spring 23 is engaged with the mounting groove 211 and is located on either side of the collar 10, along with the limiting portion 22. With the above arrangement, the retaining spring 23 and the limiting portion 22 are respectively connected to both ends of the second plug-in portion 21 and located on either side of the collar 10, preventing the second plug-in portion 21 from falling out of the collar 10, thereby securing the fixing pin 20.

[0061] Alternatively, as Figure 2 As shown, the collar 10 is provided with a plug-in protrusion 13 on its circumference, which defines an insertion hole 131. The integrated shroud removal tool 100 further includes a balancing member 50, which is inserted into the insertion hole 131. It is understood that the balancing member 50 acts as a lever with the plug-in protrusion 13 as a fulcrum. When the shroud 200 is removed from the ladle, due to the effect of gravity, the shroud 200 will sink momentarily, and the direction of sinking is often toward the side of the collar 10 facing the ladle. At this time, because the collar 10 is suspended, the operator can press down on the balancing member 50 to prevent the shroud 200 from sinking at the moment of removal, thereby preventing the shroud 200 from falling out of the collar 10.

[0062] Optionally, the position of the balancing member 50 in the socket 131 is adjustable. By adjusting the position of the balancing member 50 in the socket 131, the operator can find a position that is convenient for applying force.

[0063] Alternatively, as Figure 2 As shown, the integrated shroud removal tool 100 further includes a lifting ring 60 connected to the collar 10, and the lifting ring 60 is used to be connected to the lifting tool 400. Through the above arrangement, it is convenient to lift the collar 10 by the lifting tool 400.

[0064] In other embodiments, the lifting tool 400 may also be directly hung on the collar 10 .

[0065] Among them, such as Figure 2 As shown, the collar 10 includes a collar body 11 , the second clamping member 12 and the plug-in protrusion 13 , and the collar body 11 is ring-shaped.

[0066] Alternatively, as Figure 2 As shown, an annular weight-reducing groove 111 is provided on the inner side of the collar 10 (specifically, the collar body 11). The above arrangement can reduce the weight of the integral shroud removal tool 100 and ease the difficulty of operation for the operator.

[0067] The following combination Figure 3-Figure 7 The process of removing the shroud 200 using the integrated shroud removal tool 100 is described below:

[0068] 1. Such as Figure 3 As shown, the integrated shroud removal tool 100 is hoisted in front of the shroud 200;

[0069] 2. Such as Figure 4 As shown, the collar 10 is put onto the outside of the long shroud 200, and at the same time, the four fixing pins 20 are respectively inserted into the four pin holes 310;

[0070] 3. Such as Figure 5 As shown, the position of the collar 10 is adjusted (here, rotated counterclockwise) so that the fixing pin 20 abuts against the inner wall of the pin hole 310, and the locking pin 40 is inserted and locked in the second clamping member 12;

[0071] 4. Such as Figure 6 As shown, hold the two handpieces 30 and continue to rotate the collar 10 (here counterclockwise) to turn the long nozzle 200 to a detachable angle;

[0072] 5. Such as Figure 7 As shown, the shroud 200 is removed from the ladle. During this process, the balancing member 50 is pressed down to maintain the balance of the shroud 200 .

[0073] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
