TECHNICAL FIELD
[0001] The present application relates to the technical field of uncovering machine, and particularly relates to a hook disengaging prevention device for uncovering machine. BACKGROUND
[0002] With the development of the national steel industry, in order to solve the problem of a large amount of molten iron and dust splashing caused by the opening of the blast furnace, reduce the burn injury accident, improve the environmental level of the blast furnace, improve the operating conditions and dust removal effect of the tuyere area, in the construction of medium and large blast furnaces, the use of hook covers is increased to prevent molten iron and dust from splashing during tapping. In order to not affect the operation of opening the iron notch, the hook cover needs to be removed during the operation of the blast furnace mud gun and the opening machine, and a special device for moving the hook cover is the uncovering machine. When the uncovering machine places the hook cover, due to too much iron slag and other debris on the ground, the hook cover is lifted after being placed, which seriously causes the hook cover to disengage from the lifting hook of the uncovering machine, and the hook cover cannot be accurately lifted in the next time
[0003] In the prior art, two methods of chain fastening and plate hinged fixing are generally used to fix the hook cover and the lifting arm of the uncovering machine. The chain fastening is to fasten the hook cover pin shaft and the lifting arm hook of the uncovering machine with a chain tool. This method can effectively prevent the hook cover from disengaging in daily use, but it is troublesome to disassemble. The plate hinged fixing is to weld a fixed seat on the upper surface of the lifting arm hook, the fixed seat has two pin shaft holes, and the plate is linked with the fixed seat through a pin shaft. The plate can rotate on the fixed seat around the pin shaft. When the plate presses the upper surface of the lifting arm hook, the left pin shaft hole of the plate is aligned with the left pin shaft hole of the fixed seat, and the plate is fastened through a pin shaft, so that the plate cannot rotate, thereby pressing the pin shaft of the hook cover, so that the pin shaft cannot disengage from the lifting arm hook. When the hook cover is replaced, the pin shaft is disassembled, the plate rotates around the pin shaft, and the hook cover can be replaced. However, due to the high temperature of the blast furnace site and the large splashing of molten iron, iron slag is attached between the plate and the fixed seat, which causes the pin shaft to be blocked when rotating, so that the plate cannot rotate normally, and the risk of disengagement between the hook cover and the uncovering machine occurs.
[0004] Therefore, a hook disengaging prevention device for uncovering machine is needed to solve the above problems. Content of the utility model

[0026] As Figure 1 andFigure 2 The anti-unhooking device for uncovering machine comprises a hook 17, a fixed seat 10, a pressing plate 11, a connecting column 12 and a rotating shaft 13. One end of the hook 17 is fixedly arranged at the end of the lifting arm body 2 away from the uncovering machine 1, and the middle part of the hook 17 is in contact with the pin shaft 4 rotatably connected with the top of the hook cover 3. The fixed seat 10 with an internal cavity is fixedly arranged at the top of the lifting arm body 2, and the length direction of the fixed seat 10 is consistent with the length direction of the lifting arm body 2. The pressing plate 11 is arranged in the interior of the fixed seat 10, and slides along the length direction of the fixed seat 10 and abuts against the peripheral surface of the pin shaft 4. The connecting column 12 is arranged at the side of the pressing plate 11 close to the lifting arm body 2. One end of the rotating shaft 13 extends into the interior of the fixed seat 10 and is in gear transmission with the connecting column 12, and the other end extends to the exterior of the fixed seat 10.
[0027] In the above scheme, under normal circumstances, the pressing plate 11 is in a separated state with the pin shaft 4, and the hook cover 3 can be normally connected and separated with the hook 17. When the pin shaft 4 at the top of the hook cover 3 is in contact with the hook 17, the operator rotates one end of the rotating shaft 13 located outside the fixed seat 10. The rotation of the rotating shaft 13 drives the connecting column 12 to move through gear transmission, and the connecting column 12 drives the pressing plate 11 to slide in the interior of the fixed seat 10. With the sliding of the pressing plate 11, the pressing plate 11 gradually approaches the pin shaft 4 and finally abuts against the peripheral surface of the pin shaft 4, thereby preventing the pin shaft 4 from being unhooked from the hook 17. When it is needed to release the anti-unhooking state, the rotating shaft 13 is reversely rotated to reversely drive the connecting column 12 and the pressing plate 11 to move, so that the pressing plate 11 is separated from the pin shaft 4, and the hook cover 3 can be normally separated from the hook 17. In the present application, the direct abutment between the pressing plate 11 and the pin shaft 4 does not need to consider the influence of high-temperature iron slag and other environments, and ensures the stable connection of the hook cover 3 with the working end of the uncovering machine 1 while facilitating the disassembly of the hook cover 3 from the working end of the uncovering machine 1.
[0028] It can be implemented that one end of the rotating shaft 13 extends to the exterior of the fixed seat 10, which provides the possibility for remote control. The staff can realize the automatic control of the anti-unhooking device by installing a motor and other driving devices, and further improve the convenience and safety of operation.
[0029] The bottom of the fixed seat 10 is provided with a gap 101 for the pressing plate 11 to pass through along the length direction of the fixed seat 10. The gap 101 is in communication with the interior of the fixed seat 10, and the size of the gap 101 is matched with the size of the pressing plate 11.
[0030] In the above scheme, when the rotating shaft 13 rotates, the connecting column 12 is driven to move through the gear meshing, and the connecting column 12 in turn pushes the pressing plate 11 to slide in the fixed seat 10. The gap 101 serves as an access channel for the pressing plate 11, ensuring the smoothness of the movement of the pressing plate 11. When the pressing plate 11 slides to the position of the pin shaft 4, the pressing plate 11 entering through the gap 101 abuts against the peripheral surface of the pin shaft 4, forming a mechanical lock to prevent the pin shaft 4 from being pulled out of the hook 17. The gap 101 and the pressing plate 11 are designed to allow the pressing plate 11 to be finely adjusted according to the position of the pin shaft 4, ensuring that it can be closely abutted against the pin shaft 4 under various working conditions, thereby avoiding excessive stress concentration of the pressing plate 11 during sliding and preventing foreign matters such as iron slag from entering the inside of the fixed seat 10 to interfere with the movement of the pressing plate 11.
[0031] The upper end of the gap 101 is fixedly provided with a scraper 14, the length direction of the scraper 14 is arranged at an obtuse angle with the sliding direction of the pressing plate 11, and the lower edge of the scraper 14 abuts against the top surface of the pressing plate 11.
[0032] In the above scheme, when the pressing plate 11 slides in the fixed seat 10, the sliding movement of the pressing plate 11 will drive the relative movement of the scraper 14 due to the abutment of the lower edge of the scraper 14 against the top surface of the pressing plate 11. During the sliding process of the pressing plate 11, the scraper 14 scrapes the top surface of the pressing plate 11 to remove foreign matters such as iron slag and dust adhering to the top surface of the pressing plate 11, ensuring the normal operation of the anti-unhooking device. The length direction of the scraper 14 is arranged at an obtuse angle with the sliding direction of the pressing plate 11, and the purpose of this arrangement is that when the pressing plate 11 slides, the foreign matters scraped down by the scraper 14 are more easily discharged along the obtuse angle direction, avoiding the accumulation of foreign matters near the gap 101, and reducing the frictional resistance between the scraper 14 and the pressing plate 11 to make the sliding of the pressing plate 11 more smooth.
[0033] A mounting groove 102 is recessed on the inner wall of the fixed seat 10, a rotating bearing 15 is fixedly arranged in the groove cavity of the mounting groove 102, and the middle part of the rotating bearing 15 is fixedly connected with one end of the rotating shaft 13 located inside the fixed seat 10.
[0034] In the above scheme, the rotating bearing 15 is fixedly arranged in the groove cavity of the mounting groove 102, and the shape and size of the mounting groove 102 are adapted to the rotating bearing 15, ensuring that the rotating bearing 15 can be stably installed in the fixed seat 10 to reduce the frictional resistance between the rotating shaft 13 and the fixed seat 10. The rotating shaft 13 is supported by the rotating bearing 15, so that the rotating shaft 13 can smoothly rotate in the fixed seat 10 without shaking or deviating during rotation.
[0035] The rotating shaft 13 is fixedly provided with a limiting pin 16 in the radial direction thereof, and the limiting pin 16 is located inside the fixed seat 10 and in sliding contact with the inner wall of the fixed seat 10 away from the rotating bearing 15.
[0036] In the above scheme, when the operator rotates the rotating shaft 13 at the end outside the fixed seat 10, the rotating shaft 13 drives the limiting pin 16 to rotate. Since the limiting pin 16 is located inside the fixed seat 10, it can effectively prevent the rotating shaft 13 from being separated from the fixed seat 10 when rotating, thereby ensuring the stable connection of the rotating shaft 13 and the connecting column 12.
[0037] The scraper 14 and the fixed seat 10 are of an integrated structure. The purpose of such a setting is that, on the one hand, since the scraper 14 and the fixed seat 10 are integrated, the position of the scraper 14 is fixed. This makes the scraper 14 always accurately abut against the top surface of the pressing plate 11, ensuring that the scraper 14 can stably scrape the top surface of the pressing plate 11 to remove iron slag, dust and other sundries during the sliding process of the pressing plate 11; on the other hand, it makes the connection between the scraper 14 and the fixed seat 10 more firm, and it will not appear the phenomenon of loosening and falling off due to long-term use or external force impact.
[0038] The various embodiments in the specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other, and each embodiment mainly explains the difference from other embodiments.
[0039] The above examples are only used to illustrate the technical solutions of the present application, and are not limited to the present application; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the present application.
