A safety clamp device for preventing cracking of a furnace shell

Abstract

This utility model provides a safety clamp device to prevent furnace shell cracking, comprising: multiple connectors, each connector including an arc-shaped plate with a groove on one side and a reinforcing plate fixedly installed on the other side of each arc-shaped plate; and multiple elastic components, each elastic component being disposed inside the reinforcing plates and including a fixing tube. This safety clamp device to prevent furnace shell cracking utilizes the interplay of connectors, elastic components, and anti-slip plates. During use, the elasticity of the spring pushes the extension rod, causing the anti-slip plate to abut against the furnace body, automatically limiting the movement of the connectors. This eliminates the need for operators to hold the clamp device for extended periods during furnace heating, reducing operator fatigue.

[0003] A prior art method for preventing furnace shell cracking includes a first fixing member and a second fixing member, both of which are circular components composed of multiple arc-shaped plates connected by bolts. The opposing arc-shaped plates of the first and second fixing members are respectively provided with a first connecting head and a second connecting head, which are connected together by a tie rod. This invention is simple, easy to operate, and low in cost. It completely solves the design defects of rigid clamps and rigid connecting rods, allowing the furnace shell to expand and contract freely, both vertically and horizontally, thus completely eliminating the restriction on furnace shell cracking and preventing cracking. This results in significant social and economic benefits.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First Embodiment Please refer to the following: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 ,in, Figure 1 A schematic diagram of the first embodiment of a safety clamp device for preventing furnace shell cracking provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the connector. Figure 3 for Figure 2 The diagram shows another perspective of the structure; Figure 4 for Figure 2 The diagram shows a cross-sectional view of the elastic component. Figure 5 for Figure 3 The enlarged schematic diagram of part A is shown. A safety clamp device for preventing furnace shell cracking includes: multiple connectors 1, each of the multiple connectors 1 including an arc-shaped plate 11, a groove 13 is provided on one side of the arc-shaped plate 11, and a reinforcing plate 12 is fixedly installed on the other side of each of the multiple arc-shaped plates 11; Multiple elastic components 4 are respectively disposed inside multiple reinforcing plates 12. Each of the multiple elastic components 4 includes a fixing tube 41, which is fixedly installed inside the reinforcing plate 12. An extension rod 42 is slidably connected to one end of the fixing tube 41. A limit plate 43 is fixedly installed at one end of the extension rod 42. A spring 44 is fixedly installed on one side of the limit plate 43. Anti-slip plate 5, which is fixedly installed at the other end of the extension rod 42.

[0019] A limit component 6 is provided on one side of the anti-slip plate 5.

[0020] The limiting component 6 includes a connecting plate 61, which is fixedly installed on one side of the anti-slip plate 5. A plug-in plate 62 is slidably connected inside the connecting plate 61. A pull ring 63 is fixedly installed on the top of the plug-in plate 62. One side of the plug-in plate 62 abuts against the other side of the arc-shaped plate 11.

[0021] The anti-slip plate 5 is provided on one side of the groove 13.

[0022] A nut 2 is fixedly installed at one end of the arc-shaped plate 11, and a bolt 3 is provided inside the other end of the arc-shaped plate 11.

[0023] There are four connectors 1. After the four connectors 1 are assembled with nuts 2 and bolts 3, the shape of the inner side of the four connectors 1 can be adapted to the shape of the outer side of the furnace body. When connecting the four connectors 1, first align the two ends of the four connectors 1, then pass the bolts 3 through the inside of the end face of the arc plate 11, and then connect the bolts 3 and nuts 2 with threads to assemble the four connectors 1. By setting the groove 13, when the inner side of the arc plate 11 is attached to the outer side of the furnace body, the anti-slip plate 5 can be stored in the inner side of the groove 13, so as to avoid affecting the clamping of the arc plate 11 on the furnace body.

[0024] The working principle of the safety clamp device for preventing furnace shell cracking provided by this utility model is as follows: When in use, first assemble the four arc-shaped plates 11 directly using the nuts 2 and bolts 3. Then, place the four arc-shaped plates 11 on the outer side of the furnace body. Next, pull the pull ring 63 upwards, causing the pull ring 63 to move the plug plate 62 upwards, thus moving the plug plate 62 away from the side of the arc-shaped plates 11. At this time, the elasticity of the spring 44 pushes the extension rod 42, causing one end of the extension rod 42 to drive one side of the anti-slip plate 5 to abut against the side of the furnace body, thereby limiting the four arc-shaped plates 1. When the furnace body is heated and expanded, the operator needs to hold the connecting piece 1. After the furnace body is heated, rotate the bolt 3 so that one end of the bolt 3 is threaded inside the nut 2, thereby locking the four connecting pieces 1 together, so that the side of the arc-shaped plates 11 fits against the outer side of the furnace body. At this time, the anti-slip plate 5 will be squeezed into the inner side of the groove 13.

[0025] Compared with related technologies, the safety clamp device for preventing furnace shell cracking provided by this utility model has the following beneficial effects: The connector 1, elastic component 4 and anti-slip plate 5 work together to achieve automatic limiting of the connector 1 when in use. The elasticity of the spring 44 pushes the extension rod 42 to drive the anti-slip plate 5 to abut against the furnace body, eliminating the need for workers to hold the clamp device for a long time during the furnace heating process, thus reducing the physical exertion of the workers.

[0026] Second Embodiment Please refer to the following: Figure 6 Based on the safety clamp device for preventing furnace shell cracking provided in the first embodiment of this application, the second embodiment of this application proposes another safety clamp device for preventing furnace shell cracking. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0027] Specifically, the second embodiment of this application provides a safety clamp device for preventing furnace shell cracking, which differs in that the other end of the outer side of the fixing tube 41 is threadedly connected to a threaded cap 9, a pressure sensor 8 is fixedly installed on one side of the inner side of the threaded cap 9, and a compression plate 7 is provided on one side of the pressure sensor 8.

[0028] The extrusion plate 7 is disposed on the inner side of the fixed tube 41, and one side of the extrusion plate 7 abuts against one end of the spring 44.

[0029] The working principle of the safety clamp device for preventing furnace shell cracking provided by this utility model is as follows: When the arc plate 11 is locked to the outer side of the furnace body, the anti-slip plate 5 will be located on the inner side of the groove 13. At this time, the extension rod 42 will push the spring 44, which will push the compression plate 7, and then the compression plate 7 will compress the pressure sensor 8. The value of the pressure sensor 8 at this time will be recorded. In subsequent use, when the value of the pressure sensor 8 changes significantly, the operator needs to re-lock the four connecting parts 1.

[0030] Compared with related technologies, the safety clamp device for preventing furnace shell cracking provided by this utility model has the following beneficial effects: By installing a threaded cap 9, a pressure sensor 8, and a pressing plate 7 on the fixed pipe 41, when the arc plate 11 is locked to the outer side of the furnace body, the extension rod 42 pushes the spring 44 to press the pressing plate 7, causing the pressure sensor 8 to generate an initial value. During subsequent use, if the furnace shell changes its clamping force due to thermal expansion and contraction, the value of the pressure sensor 8 will change accordingly. The operator can promptly detect the loosening of the clamping device based on the change in the value of the pressure sensor 8, thereby enabling timely re-tightening of the connecting parts and ensuring the continuous and effective protection of the furnace shell by the clamping device, further improving the safety and reliability of the device.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
