Description

Technical Field

[0001] This utility model relates to the field of air vent sleeve installation technology, and in particular to a small sleeve spherical protector. Background Technology

[0002] The tuyere sleeve is an important piece of equipment in the blast furnace air intake system. During operation, hot air is sent into the blast furnace through the tuyere sleeve. Due to its special high-temperature and high-heat working environment, the tuyere sleeve is prone to damage and needs to be replaced regularly.

[0003] In existing technologies, firstly, many companies cannot use auxiliary equipment due to insufficient platform space at the air inlet, and can only rely on manual handling for the installation of the air vent sleeves. During the installation process, it is still necessary to first use a battering rod to insert the air vent sleeve into the air vent, and then use the battering rod to strike the air vent sleeve to fix it. In this traditional installation method, it is easy to cause scratches and damage to the spherical surface of the inner wall of the sleeve during the impact, affecting the service life of the sleeve. Secondly, many auxiliary equipment do not have the function of adjusting the support device, which means that one piece of equipment can only be used for one size of air vent sleeve, affecting work efficiency and increasing work costs.

[0004] Therefore, a small-sized spherical protector is needed in the current environment to solve the technical problems mentioned in the background. Utility Model Content

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to the present utility model are shown in the drawings, not all of the structures. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] Please see Figures 1 to 2 The present invention provides a small spherical protector, which includes a guide shaft 1, a protective plate 2, an adjustment component 3, and a support component 4.

[0020] The protective plate 2 is mounted on the guide shaft 1, the adjustment component 3 is mounted on one end of the guide shaft 1 near the protective plate 2, and the support component 4 is mounted on the guide shaft 1 and connected to one end of the protective plate 2.

[0021] Among them, the guide shaft 1 serves as the installation reference, providing a stable working environment for the small spherical protector. The protective plate 2 plays a protective role, preventing the impact rod from directly contacting the small sleeve of the air outlet during installation, thereby avoiding the phenomenon of the impact rod damaging the inner wall of the small sleeve of the air outlet.

[0022] Meanwhile, during the installation of the air vent sleeve, the air vent sleeve needs to be first put on from the end of the guide shaft 1 away from the protective plate 2, then the air vent sleeve is moved to the area of ​​the support component 4, and finally the support component 4 that cooperates with the adjustment component 3 is moved at the thread on the guide shaft 1 by rotating the adjustment component 3, so that the support component 4 can support the air vent sleeve.

[0023] Furthermore, after the support component 4 supports the air vent sleeve, one end of the air vent sleeve is in contact with one end of the protective plate 2. Finally, the end of the protective plate 2 that is not in contact with the air vent sleeve is struck with a batter, so that the batter can achieve the installation purpose without directly contacting the air vent sleeve.

[0024] In this embodiment, the guide shaft 1 is threaded at both ends.

[0025] The guide shaft 1 has a long thread and a short thread at its two ends. The adjustment component 3 is installed at the short thread, and the support component 4 is installed at the long thread, so that the adjustment component 3 and the support component 4 can move on the two thread lines.

[0026] In this embodiment, the knob 31 is installed at one end of the guide shaft 1 near the protective plate 2, the limiting step 32 is installed on the guide shaft 1, and one end of the limiting step 32 is connected to the protective plate 2.

[0027] Among them, the limiting step 32 not only facilitates the installation and positioning of parts, but also improves strength and rigidity;

[0028] At the same time, when the air vent sleeve moves to the support component 4, the knob 31 is rotated to make the guide shaft 1 start to rotate. The guide shaft 1 then drives the support component 4 to move. By continuously rotating the knob 31, the support component 4 is made to fit against the inner wall of the air vent sleeve. When the support component 4 is completely fitted against the inner wall of the air vent sleeve, the knob 31 can no longer be rotated, thereby achieving the purpose of fixing the support air vent sleeve.

[0029] Furthermore, since the sizes of the air vent sleeves are not uniform, during installation, simply rotating knob 31 is sufficient to control the support component 4 to fit against the inner wall of the air vent sleeve. When encountering a large-sized air vent sleeve, rotating knob 31 counterclockwise until it can no longer be rotated, at which point the support component 4 is properly fitted against the inner wall of the air vent sleeve. Conversely, when encountering a small-sized air vent sleeve, rotating knob 31 clockwise lowers the height of the support component 4. Then, the air vent sleeve is moved to the support component 4. Finally, rotating knob 31 counterclockwise raises the height of the support component 4. When knob 31 can no longer be rotated, the sleeve is securely fixed. Through the cooperation of knob 31 and support component 4, the fixed support of air vent sleeves of different sizes can be achieved, thereby improving work efficiency.

[0030] In this embodiment, the rotating sleeve 41 is mounted on the guide shaft 1, and one end of the rotating sleeve 41 is connected to the protective plate 2. The threaded sleeve 42 is mounted on the end of the guide shaft 1 away from the protective plate 2. The support part 43 is mounted on the rotating sleeve 41 and the threaded sleeve 42.

[0031] Among them, the rotating sleeve 41 and the threaded sleeve 42 together play a supporting role, providing a stable working environment for the support assembly 4;

[0032] Meanwhile, the rotating sleeve 41 is connected to the protective plate 2. The rotating sleeve 41 can rotate but cannot move, while the threaded sleeve 42 can rotate. When the knob 31 drives the guide shaft 1 to rotate counterclockwise, the threaded sleeve 42 will rotate on the thread of the guide shaft 1. As the guide shaft 1 continues to rotate, the distance between the rotating sleeve 41 and the threaded sleeve 42 gradually decreases. At this time, as the distance decreases, the support group 43 installed on the two sleeves will rise accordingly, thereby achieving the purpose of fitting the inner wall of the air vent sleeve. Conversely, when the knob 31 drives the guide shaft 1 to rotate clockwise, the distance between the rotating sleeve 41 and the threaded sleeve 42 gradually increases. At this time, as the distance increases, the support group 43 installed on the two sleeves will decrease accordingly. Thus, when installing air vent sleeves of different sizes on the small sleeve spherical protector, the installation efficiency of the air vent sleeve is made more efficient by lowering and raising the height.

[0033] In this embodiment, a plurality of first support rods 431 are respectively installed at the top and bottom of the rotating sleeve 41, and a plurality of second support rods 432 are respectively installed at the top and bottom of the threaded sleeve 42. The plurality of first support rods 431 and the plurality of second support rods 432 correspond one-to-one, and one end of the first support rod 431 is connected to one end of the second support rod 432.

[0034] Among them, the rotating sleeve 41 and the threaded sleeve 42 are respectively equipped with two first support rods 431 and two second support rods 432. When the distance between the two sleeves gradually gets closer, the included angle between the first support rod 431 and the second support rod 432 will gradually decrease until they fit against the inner wall of the air outlet sleeve. When the distance between the two sleeves gradually gets farther, the included angle between the first support rod 431 and the second support rod 432 will gradually increase until it tends to be horizontal, so that the air outlet sleeve can be put into the small sleeve spherical protector more quickly and efficiently.

[0035] At the same time, when the connection between the first support rod 431 and the second support rod 432 is attached to the inner wall of the tuyer sleeve, the tuyer sleeve is fixed and supported. At this time, one end of the tuyer sleeve is attached to the protective plate, and then the other end of the protective plate is struck by the impact rod. The force brought by the impact makes the tuyer sleeve fit into the blast furnace air inlet, so as to achieve the goal of fitting the tuyer sleeve into the blast furnace air inlet without damaging the inner wall of the tuyer sleeve.

[0036] In summary, this small spherical sleeve protector includes a guide shaft 1, a protective plate 2, an adjustment component 3 for adjusting the position, and a support component 4 for supporting and fixing the small air vent sleeve. The protective plate 2 is mounted on the guide shaft 1, the adjustment component 3 is mounted on one end of the guide shaft 1 near the protective plate 2, and the support component 4 is mounted on the guide shaft 1 and connected to one end of the protective plate 2. This small spherical sleeve protector, through the design of each structure, avoids scratches and damage to the inner spherical surface of the small air vent sleeve caused by the impact rod during installation, thus improving the service life of the small air vent sleeve. Furthermore, the threaded rotation design allows the small spherical sleeve protector to adapt to more sizes of small air vent sleeves, improving work efficiency.
