[0026] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0027] Reference below Figure 1-Figure 4 A regenerator pulling nozzle plate tool according to an embodiment of the present application is described.

[0028] According to some embodiments of the present application, Figure 1 and Figure 4 As shown, the heat storage chamber nozzle plate pulling tool 1 includes a pulling rod 2, a hook body 3 and a handle 4.

[0029] The hook body 3 is fixedly connected to one end of the pull rod 2, and the hook body 3 is arranged in a concave 31 on one side facing the pull rod 2, and the notch of the concave 31 faces the pull rod 2. The handle 4 is fixedly connected to the pull rod 2 and is spaced apart from the hook body 3.

[0030] The hook body 3 is fixedly connected to the end of the pull rod 2, and the hook body 3 extends radially along the pull rod 2 so that the hook body 3 can directly contact the nozzle plate, wherein the hook body 3 is set in a recess 31 on the side facing the pull rod 2. When the hook body 3 contacts the nozzle plate, it contacts the nozzle plate through the position of the recess 31 to increase the contact area and improve the stability of hooking the nozzle plate. By setting the notch of the recess 31 toward the pull rod 2, the nozzle plate can be pulled in the direction close to the pull rod 2, wherein the recess 31 can be set in an arc shape, or in a V shape or a concave shape. The handle 4 is set at a distance from the hook body 3. In actual use, part of the pull rod 2 extends into the heat storage chamber, and the handle 4 is set at the part of the pull rod 2 outside the heat storage chamber, so that the worker can grasp the handle 4 to operate the pull rod 2.

[0031] In actual implementation, the worker extends one end of the pull rod 2 provided with the hook 3 into the heat storage chamber, adjusts the position of the hook 3 in the heat storage chamber by grasping the handle 4 and the pull rod 2, hooks the nozzle plate at the recessed position 31 of the hook 3, and pulls the handle 4 and the pull rod 2 to pull the nozzle plate out for easy adjustment.

[0032] According to the heat storage chamber nozzle plate pulling tool 1 provided in the embodiment of the present application, workers can easily operate the tool by grasping the handle 4 to pull out and adjust the nozzle plate, thereby improving the convenience of operation; the recess 31 design of the hook body 3 improves the contact stability with the nozzle plate, reduces the risk of the nozzle plate falling off, and increases the stability of operation. The convenient operation method helps to shorten the operation time and improve work efficiency.

[0033] According to some embodiments of the present application, Figure 1 and Figure 2 As shown, the hook body 3 may include a hook plate, the thickness direction of the hook plate may extend along the radial direction of the pull rod 2 , and the recess 31 may be provided on the side of the hook plate facing the pull rod 2 .

[0034] In this embodiment, the hook body 3 may include a hook plate, which may be made of a plate-like material. It is understood that when the pull rod 2 pulls the nozzle plate, it generally moves along the axial direction of the pull rod 2. When the hook plate pulls the nozzle plate, the hook plate bears the force along the axial direction of the pull rod 2. By extending the thickness direction of the hook plate along the radial direction of the pull rod 2, the hook plate is made larger in the axial direction of the pull rod 2, thereby improving the bearing capacity of the hook plate and preventing it from deforming and failing. The hook plate is provided with a recess 31 on the side facing the pull rod 2. The recess 31 may be formed by machining or stamping, which is simple to process. In addition, the hook plate is made of a plate material, which can save materials and reduce production costs.

[0035] According to some embodiments of the present application, Figure 1 As shown, the pull rod 2 includes at least a first section 21 and a second section 22 detachably connected along the length direction, the end of the first section 21 away from the second section 22 can be connected to the hook body 3, and the end of the second section 22 away from the first section 21 is connected to the handle 4.

[0036] In this embodiment, the pull rod 2 may include a first section 21 and a second section 22, both of which extend along the length direction of the pull rod 2, and the end of the first section 21 away from the second section 22 is connected to the hook body 3, and the end of the second section 22 away from the first section 21 is connected to the handle 4, and the ends of the first section 21 and the second section 22 close to each other are detachably connected. Because the regenerator generally has a certain depth, in order for the hook body 3 to hook the nozzle plate, the pull rod 2 needs to have a certain length, which is determined according to the depth of the regenerator. For example, taking a 7.63-meter coke oven as an example, the lengths of the first section 21 and the second section 22 can both be 4 meters, and the first section 21 and the second section 22 are assembled to form an 8-meter-long pull rod 2.

[0037] By setting the pull rod 2 into two sections, the storage and use of the tool can be facilitated. When storing, the first section 21 and the second section 22 are disassembled and stored to reduce the occupied space. When in use, the first section 21 and the second section 22 can be assembled and connected.

[0038] According to some embodiments of the present application, Figure 1 , Figure 2 and Figure 3 As shown, one end of the first section 21 and the second section 22 close to each other may be provided with a screw connection structure, and the first section 21 and the second section 22 may be threadedly connected through the screw connection structure.

[0039] In this embodiment, the ends of the first section 21 and the second section 22 close to each other may be provided with a screw connection structure. For example, the end of the first section 21 close to the second section 22 may be provided with an external thread 221, and the end of the second section 22 close to the first section 21 may be provided with a sleeve 211, and the sleeve 211 is provided with an internal thread. The first section 21 and the second section 22 are connected by threading the external thread 221 of the first section 21 with the sleeve 211. In another example, such as Figure 2 and Figure 3 As shown, an end of the second section 22 close to the first section 21 may be provided with an external thread 221 , and an end of the first section 21 close to the second section 22 may be provided with a sleeve 211 .

[0040] In actual implementation, the outer thread 221 can be directly processed on the circumference of the first section 21 near the end of the second section 22. When the pull rod 2 is made of metal, the sleeve 211 can be directly welded to the end of the second section 22 near the first section 21, and the structural strength is high. The screw connection structure is firmly connected and has high stability.

[0041] According to some embodiments of the present application, Figure 1 , Figure 2 and Figure 3 As shown, a connecting piece 24 may be provided on the first section 21 , and a matching piece 25 may be provided on the second section 22 . The connecting piece 24 may be detachably connected to the matching piece 25 .

[0042] In this embodiment, a connecting piece 24 is provided on the first section 21, and a matching piece 25 detachably connected to the connecting piece 24 is provided on the second section 22, wherein the connecting piece 24 is provided on a side of the first section 21 close to the screw connection structure, and the matching piece 25 is provided on a side of the second section 22 close to the screw connection mechanism. After the first section 21 and the second section 22 are threadedly connected, the connecting piece 24 and the matching piece 25 can be connected to further improve the connection strength between the first section 21 and the second section 22. After the pull rod 2 is extended into the heat storage chamber, damage to the screw connection structure due to excessively high temperature in the heat storage chamber or excessive bending moment on the pull rod 2 is avoided.

[0043] For example, Figure 1As shown, the connecting member 24 may include a first nut, which is welded to the first section 21, and the matching member 25 may be a second nut, which is welded to the second section 22. The first nut and the second nut may be connected by a bolt passing through the first nut and the second nut, or may be connected by a steel wire 26 passing through the first nut and the second nut.

[0044] In other embodiments, the ends of the first section 21 and the second section 22 close to each other can be connected by a snap-fit ​​structure. For example, a snap-fit ​​protrusion is provided at the end of the first section 21 close to the second section 22, and a snap-fit ​​groove is provided at the end of the second section 22 close to the first section 21, and the connection is achieved by the cooperation of the snap-fit ​​protrusion and the snap-fit ​​groove; or a buckle is provided at the end of the first section 21 close to the second section 22, and a movably arranged buckle is provided at the end of the second section 22 close to the first section 21, and a fixed connection is achieved by the snap-fit ​​cooperation of the buckle and the buckle. The snap-fit ​​structure has fast connection speed and high efficiency.

[0045] In some other embodiments, the first section 21 and the second section 22 may be connected by a latch structure. For example, the first section 21 and the second section 22 may be provided with corresponding plug-in slots. When the first section 21 and the second section 22 are connected, the end of the first section 21 extends into the second section 22 so that the plug-in slots of the two correspond to each other, and the latch penetrates the plug-in slot to achieve a fixed connection. The latch structure is provided to achieve fast connection speed and high stability.

[0046] According to some embodiments of the present application, Figure 4 As shown, the pull rod 2 may further include at least one extension section 23 , and the extension section 23 is detachably connected between the first section 21 and the second section 22 .

[0047] In this embodiment, the pull rod 2 can also include at least one extension section 23, which is detachably connected between the first section 21 and the second section 22. After the first section 21, the extension section 23, and the second section 22 are assembled and spliced, the entire pull rod 2 is formed. By setting the extension section 23, on the one hand, the length of the first section 21 and the second section 22 can be reduced. On the other hand, the heat storage chamber nozzle plate pulling tool 1 can be adapted to heat storage chambers of various sizes. When the size of the heat storage chamber is large, the length of the pull rod 2 can be extended by adding an extension section 23. When the size of the heat storage chamber is small, the extension section 23 does not need to be installed.

[0048] The number of the extended sections 23 is not limited here, and can be 1, 2, 3 or more than 3, which is determined according to the length of each section and the depth of the heat storage chamber, and is not specifically limited here.

[0049] The ends of the extension section 23 may be provided with a screw connection structure, and the screw connection structures at both ends of the extension section 23 may be threadedly matched with the screw connection structures of the first section 21 and the second section 22, respectively. It is understandable that when multiple extension sections 23 are provided, the extension sections 23 may be sequentially connected by screw connection structures.

[0050] In some embodiments, Figure 4 As shown, when an extension section 23 is connected between the first section 21 and the second section 22, the ends of the extension section 23 connected to the first section 21 and the second section 22 are respectively provided with a fitting 25 and a connecting piece 24, the fitting 25 on the extension section 23 can be connected to the connecting piece 24 of the first section 21, and the connecting piece 24 on the extension section 23 can be connected to the fitting 25 of the second section 22, so as to enhance the stability of the connection.

[0051] According to some embodiments of the present application, Figure 1 and Figure 3 As shown, the handle 4 can be arranged in a rod shape, and the extension direction of the handle 4 is connected to the extension direction of the pull rod 2 at an angle.

[0052] In this embodiment, the handle 4 is configured to be rod-shaped, so that it is convenient for workers to hold and adjust. By configuring the extension direction of the handle 4 to be at an angle to the extension direction of the pull rod 2, the worker can grasp the handle 4 and exert force to drive the pull rod 2 to rotate around the axis of the pull rod 2 or to drive the pull rod 2 to move axially, thereby improving the convenience of using the tool.

[0053] According to some embodiments of the present application, Figure 1 and Figure 3 As shown, the handle 4 can be arranged perpendicular to the pull rod 2 , and the middle section of the handle 4 is fixedly connected to the pull rod 2 .

[0054] In this embodiment, the handle 4 is vertically connected to the pull rod 2 so that the worker can grasp the handle 4 to exert force, which is more efficient and convenient to use. The middle section of the handle 4 is fixedly connected to the pull rod 2, so that when the worker grasps the handle 4 with both hands to exert force, the force on the pull rod 2 and the nozzle plate is more balanced, thereby improving the stability when pulling the nozzle plate and making it easier to control.

[0055] In other embodiments, one end of the handle 4 may be fixedly connected to the pull rod 2 , and the worker may hold the pull rod 2 with one hand and the handle 4 with the other hand.

[0056] According to some embodiments of the present application, Figure 1 As shown, the pull rod 2 is a steel pipe, and the handle 4 is connected to one end of the steel pipe away from the hook body 3.

[0057] In this embodiment, by setting the pull rod 2 to be a steel pipe, the weight of the pull rod 2 is reduced while ensuring the structural strength of the pull rod 2, which facilitates the operation of the pull rod 2. By connecting the handle 4 to the end of the steel pipe away from the hook body 3, manual operation is facilitated and interference between the handle 4 and the entrance of the heat storage chamber is avoided.

[0058] The steel pipe may be a round steel pipe or a square pipe, without any specific limitation.

[0059] In other embodiments, the handle 4 can be arranged at a certain distance from the end of the steel pipe away from the hook body 3 to facilitate multiple people to operate the tool at the same time.

[0060] According to some embodiments of the present application, the pull rod 2 , the hook body 3 and the handle 4 may all be made of metal materials, and the hook body 3 and the handle 4 may be respectively welded to the pull rod 2 .

[0061] In this embodiment, the pull rod 2, the hook body 3 and the handle 4 can be made of metal. For example, the pull rod 2 can be a steel pipe, the hook body 3 can be a steel plate, and the handle 4 can be a steel pipe. The hook body 3 and the handle 4 can be welded to the pull rod 2 respectively, with high connection strength, stable structure, convenient material acquisition and low production cost.

[0062] It is understandable that the pull rod 2 and the hook body 3 can also be made of other high temperature resistant metal materials, such as stainless steel, aluminum alloy, etc.

[0063] In another embodiment, the handle 4 may be made of other non-metallic materials such as nylon, polycarbonate, etc. The handle 4 is fixedly connected to the pull rod 2 by plugging or other connection methods.
