A finishing mill housing that prevents injury

Abstract

The present invention discloses a finishing mill outer cover that prevents injury, which relates to the technical field of finishing mill accessories and includes a finishing mill outer cover and a mounting plate. A deflection head is fixedly sleeved outside the finishing mill outer cover. In this anti-injury finishing mill outer cover, through the combined use of an electromagnet, a limiting spring, a sleeve pipe, and a positioning pin, when the finishing mill outer cover is in a closed state, the positioning pin is squeezed by the outside of the deflection shaft, retracts into the interior of the sleeve pipe and compresses the limiting spring. When the finishing mill outer cover is in an open state, the limiting spring squeezes the limiting iron disc and the positioning pin under the action of its own elastic force, so that the bottom end of the positioning pin is sleeved in the positioning jack of the deflection shaft, locking the finishing mill outer cover, thereby ensuring the stability of the anti-injury finishing mill outer cover in the open state. When it needs to be closed, the electromagnet can be energized to generate a strong magnetic field to attract the limiting iron disc, so that the end of the positioning pin withdraws from the positioning jack.

Description

Technical Field

[0001] The present invention relates to the technical field of finishing mill accessories, and more specifically, to a protective cover for a finishing mill that prevents injury to people. Background Art

[0002] A finishing mill is an instrument used in the field of power and electrical engineering. A finishing mill is a finished product rolling mill and is the core part of hot-rolled strip production. The quality level of the rolled products mainly depends on the technical equipment level and control level of the finishing mill unit. Therefore, in order to obtain high-quality excellent products, a large number of new equipment, new technologies, new processes, and high-precision detection instruments are adopted in the finishing mill unit, such as hot-rolled strip shape control equipment, fully hydraulic screwdown devices, optimized shearing devices, hot-rolled oil lubrication processes, etc. In addition, in order to protect the equipment and the operating environment from pollution, a dust removal device is provided in the finishing mill unit.

[0003] Since various mechanisms are provided in the finishing mill, in order to protect these mechanisms when not working, a protective cover for protecting them is assembled on the outside of some finishing mills. During the working process of the finishing mill, the cover needs to be opened, and when not working, the cover is lowered to protect the equipment. However, the existing protective covers of finishing mills still have certain deficiencies in actual use. The opening and closing operations of the existing protective covers of finishing mills are realized by a lead screw. After the finishing mill is opened and during the actual working process, equipment failures and operation errors may occur, resulting in the situation that the cover of the finishing mill has a free fall, which poses a danger to the staff. Therefore, we have designed a protective cover for a finishing mill that prevents injury to people to solve the above problems. Summary of the Invention

[0004] In view of the above problems, the present invention proposes a protective cover for a finishing mill that prevents injury to people to improve the above problems.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A protective cover for a finishing mill that prevents injury to people, including a finishing mill cover and a mounting plate. A deflection head is fixedly sleeved outside the finishing mill cover. A mounting seat is welded and connected to the mounting plate. A deflection cavity matching the deflection head is provided in the mounting seat, and the mounting seat and the deflection head are movably connected through a deflection shaft. Deflection seats that correspond one by one and are evenly distributed are assembled outside the finishing mill cover and the mounting plate. An electric telescopic rod is movably assembled between the upper two groups of deflection seats. A buffer sleeve and a piston rod are movably sleeved between the lower two groups of deflection seats. A communication pipe and an alarm whistle are fixedly sleeved outside the buffer sleeve. A sleeve pipe corresponding to the position of the deflection shaft is fixedly sleeved on the mounting seat, and a positioning pin is movably sleeved in the sleeve pipe.

[0006] Further, a limiting iron disk is fixedly sleeved on the top end of the positioning pin. A limiting spring is fixedly connected between the limiting iron disk and the sleeve pipe. An electromagnet is fixedly sleeved on the top of the sleeve pipe.

[0007] Further, a controller is assembled outside the finisher housing. The controller is electrically connected to both the electric telescopic rod and the electromagnet.

[0008] Further, the length value of the buffer sleeve matches the length value of the electric telescopic rod. A piston cavity matching the piston rod is provided in the buffer sleeve. A buffer spring is fixedly connected between the buffer sleeve and the piston rod.

[0009] Further, a first through hole communicating with the piston cavity is provided outside the buffer sleeve. The position of the first through hole corresponds to that of the connecting pipe. A second through hole corresponding to the first through hole one by one is provided inside the connecting pipe.

[0010] Further, the alarm siren is sleeved outside the connecting pipe, and the alarm siren is in communication with the connecting pipe.

[0011] Further, the end of the positioning pin extends to the inside of the mounting seat. A positioning jack matching the bottom end of the positioning pin is provided on the deflecting shaft.

[0012] Further, uniformly distributed reinforcing plates are welded between the mounting seat and the mounting plate. The reinforcing plates are triangular in structure and are symmetrically distributed on the upper and lower sides of the mounting seat.

[0013] A finisher housing for preventing injury provided by the present invention has the following beneficial effects:

[0014] 1. For the finisher housing for preventing injury, through the combined use of the electromagnet, the limiting spring, the sleeve pipe and the positioning pin, when the finisher housing of the finisher housing for preventing injury is in the closed state, the positioning pin is squeezed by the outside of the deflecting shaft, retracts into the inside of the sleeve pipe and compresses the limiting spring. When the finisher housing is in the open state, the limiting spring squeezes the limiting iron disk and the positioning pin under the action of its own elastic force, so that the bottom end of the positioning pin is sleeved in the positioning jack of the deflecting shaft, locking the finisher housing, thereby ensuring the stability of the finisher housing for preventing injury in the open state. When it needs to be closed, the electromagnet can be energized to generate a strong magnetic field to attract the limiting iron disk, so that the end of the positioning pin exits from the positioning jack, which not only ensures the stability of the finisher housing for preventing injury in the open state, but also makes the operation of releasing the fixation simple and convenient.

[0015] 2. The anti-injury finisher housing, through the combined use of the piston rod, buffer sleeve, buffer spring and the first through hole, enables the anti-injury finisher housing to be deflected by the electric telescopic rod during operation, achieving opening and closing. During the opening and closing process of the finisher housing, the piston rod moves in the buffer sleeve following the movement of the finisher housing. The air between the buffer sleeve and the piston rod is discharged or enters through the first through hole. At the same time, during the movement of the piston rod, the buffer spring is compressed or stretched. Through the buffering of the buffer spring in cooperation with the air intake and discharge, the process of deflecting the finisher housing is buffered, making the opening and closing speed of the finisher housing slow, preventing the situation of free fall, and improving the safety during the opening and closing process of the anti-injury finisher housing.

[0016] 3. The anti-injury finisher housing, through the combined use of the first through hole, the second through hole, the connecting pipe and the alarm siren, enables the air between the buffer sleeve and the piston rod to be discharged or enter through the first through hole during the opening and closing process of the anti-injury finisher housing. The air flowing through the first through hole enters the connecting pipe through the second through hole inside the connecting pipe, and then passes through the inside of the alarm siren. The alarm siren generates an alarm sound during the passage of air, reminding the nearby staff to pay attention, thereby further improving the safety during the operation of the anti-injury finisher housing.

[0026] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1 to 5 , the present invention provides a technical solution: an anti-injury outer cover of a finishing mill, including an outer cover 1 of the finishing mill and a mounting plate 2. A deflection head 11 is fixedly sleeved outside the outer cover 1 of the finishing mill. A mounting seat 8 is welded to the mounting plate 2. A deflection cavity 6 matching the deflection head 11 is provided in the mounting seat 8, and the mounting seat 8 and the deflection head 11 are movably connected through a deflection shaft 17. Reinforcing plates are welded between the mounting seat 8 and the mounting plate 2 and are evenly distributed. The reinforcing plates welded between the mounting seat 8 and the mounting plate 2 can enhance the connection stability between the mounting seat 8 and the mounting plate 2. The reinforcing plates are in a triangular structure and are symmetrically distributed on the upper and lower sides of the mounting seat 8. The triangular structure can ensure the load-bearing capacity of the reinforcing plates and provide a stable assembly and movement environment for the outer cover 1 of the finishing mill.

[0028] Deflection seats 5 corresponding one by one and evenly distributed are assembled outside the outer cover 1 of the finishing mill and the mounting plate 2. An electric telescopic rod 4 is movably assembled between the two upper deflection seats 5. A buffer sleeve 9 and a piston rod 7 are movably sleeved between the two lower deflection seats 5. The length value of the buffer sleeve 9 matches the length value of the electric telescopic rod 4, and a piston cavity matching the piston rod 7 is provided in the buffer sleeve 9. During the opening and closing process of the outer cover 1 of the finishing mill, the piston rod 7 can move in the buffer sleeve 9 following the movement of the outer cover 1 of the finishing mill. The air between the buffer sleeve 9 and the piston rod 7 is discharged or enters through the first through hole 14.

[0029] Please refer to Figures 2 to 6, a buffer spring 15 is fixedly connected between the buffer sleeve 9 and the piston rod 7. At the same time, during the movement of the piston rod 7, the buffer spring 15 is compressed or stretched. Through the buffering of the buffer spring 15 in cooperation with the air suction and release, buffering is carried out during the deflection of the housing 1 of the finishing mill. A communicating pipe 12 and an alarm whistle 13 are fixedly sleeved outside the buffer sleeve 9. A first through hole 14 communicating with the piston chamber is opened outside the buffer sleeve 9. The air between the buffer sleeve 9 and the piston rod 7 is discharged or enters through the first through hole 14 during the movement of the piston rod 7.

[0030] The position of the first through hole 14 corresponds to that of the communicating pipe 12. A second through hole 16 corresponding to the first through hole 14 one by one is opened inside the communicating pipe 12. The air flowing through the first through hole 14 can enter the communicating pipe 12 through the second through hole 16 inside the communicating pipe 12. The alarm whistle 13 is sleeved outside the communicating pipe 12. The air entering the communicating pipe 12 will pass through the inside of the alarm whistle 13, and the alarm whistle 13 and the communicating pipe 12 are interconnected. The alarm whistle 13 generates an alarm sound during the passage of air to remind the nearby staff to pay attention. A sleeve pipe 10 corresponding to the position of the deflection shaft 17 is fixedly sleeved on the mounting seat 8. A positioning pin 19 is movably sleeved in the sleeve pipe 10. The end of the positioning pin 19 extends to the inside of the mounting seat 8. When the bottom end of the positioning pin 19 is sleeved in the positioning jack 18 of the deflection shaft 17, the housing 1 of the finishing mill can be locked to ensure the stability of the housing 1 of the finishing mill in the open and closed states.

[0031] Please refer to Figures 6 to 7 , a positioning jack 18 matching the bottom end of the positioning pin 19 is opened on the deflection shaft 17. During the deflection of the housing 1 of the finishing mill, the bottom end of the positioning pin 19 is kept retracted into the sleeve pipe 10 under the extrusion of the outside of the deflection shaft 17. A limit iron disc 22 is fixedly sleeved on the top end of the positioning pin 19. When the housing 1 of the finishing mill is in the closed state, the positioning pin 19 is under the extrusion of the outside of the deflection shaft 17 and retracts into the inside of the sleeve pipe 10 and compresses the limit spring 21.

[0032] A limiting spring 21 is fixedly connected between the limiting iron disc 22 and the sleeve pipe 10. An electromagnet 20 is fixedly sleeved on the top of the sleeve pipe 10. When the outer cover 1 of the finishing mill is in the open state, the limiting spring 21 presses the limiting iron disc 22 and the positioning pin 19 under the action of its own elastic force, so that the bottom end of the positioning pin 19 extends out of the sleeve pipe 10. After the electromagnet 20 is energized, it can generate magnetism to attract the limiting iron disc 22, so that the positioning pin 19 retracts into the sleeve pipe 10 and compresses the limiting spring 21. A controller 3 is assembled outside the outer cover 1 of the finishing mill. The controller 3 can control the electric telescopic rod 4 and the deflecting head 11 to be energized and work. After the electromagnet 20 is energized, it generates strong magnetism to attract the limiting iron disc 22. The controller 3 is electrically connected to the electric telescopic rod 4 and the electromagnet 20, so that the end of the positioning pin 19 withdraws from the positioning jack 18, releasing the fixation of the outer cover 1 of the finishing mill. During the working process, the electric telescopic rod 4 pulls the outer cover 1 of the finishing mill to deflect, realizing the opening and closing of the outer cover 1 of the finishing mill. The principle and the using process of this controller 3 are the same as those of the prior art and will not be elaborated here.

[0033] In summary, for a finisher housing that prevents injury, during use, select a suitable area outside the finisher as the mounting plate 2, weld and connect the mounting seat 8 on the mounting plate 2, and movably connect the deflector head 11 outside the finisher housing 1 with the deflection cavity 6 opened in the mounting seat 8 through the deflection shaft 17. When the finisher housing 1 is in the closed state, the positioning pin 19 is squeezed by the outside of the deflection shaft 17, retracts into the inside of the sleeve pipe 10 and compresses the limit spring 21. When the finisher housing 1 is in the open state, the limit spring 21 squeezes the limit iron disc 22 and the positioning pin 19 under the action of its own elastic force, so that the bottom end of the positioning pin 19 is sleeved in the positioning jack 18 of the deflection shaft 17 to lock the finisher housing 1. When it is necessary to close the finisher housing 1, the controller 3 controls the electric telescopic rod 4 and the deflector head 11 to be powered on and work. The electromagnet 20 can be powered on to generate a strong magnetic field to attract the limit iron disc 22, so that the end of the positioning pin 19 withdraws from the positioning jack 18 to release the fixation of the finisher housing 1. During the working process of the electric telescopic rod 4, it pulls the finisher housing 1 to deflect, realizing the opening and closing of the finisher housing 1. During the opening and closing process of the finisher housing 1, the piston rod 7 moves in the buffer sleeve 9 following the movement of the finisher housing 1. The air between the buffer sleeve 9 and the piston rod 7 is discharged or enters through the first through hole 14. At the same time, during the movement of the piston rod 7, the buffer spring 15 is compressed or stretched. Through the buffering of the buffer spring 15 in cooperation with the air suction and release, the deflection process of the finisher housing 1 is buffered, so that the opening and closing speed of the finisher housing 1 is slow, preventing the situation of free fall. The air between the buffer sleeve 9 and the piston rod 7 is discharged or enters through the first through hole 14. The air flowing through the first through hole 14 enters the connecting pipe 12 through the second through hole 16 inside the connecting pipe 12, and then passes through the inside of the alarm whistle 13. The alarm whistle 13 generates an alarm sound during the passage of the air to remind the nearby staff to pay attention, and the opening and closing process of the entire finisher housing that prevents injury is completed.
