Detailed Implementation

[0023] The embodiments of this utility model will now be described with reference to the accompanying drawings.

[0024] This utility model provides a support device for the construction of an annealing furnace arch, which is used in the field of furnace construction technology. Compared with the standardized support tools in the prior art that are adapted to the curvature, length and height of the arch, it can be applied to the construction of arches of different specifications, realizes reuse, reduces material and construction costs, and is more convenient to move between different construction parts without repeated installation and disassembly, thus reducing workload and improving construction efficiency.

[0025] like Figures 1 to 3 As shown in the figure, this utility model embodiment proposes a masonry support device for an annealing furnace arch, including a bottom support 1, with support limiting frames 2 provided at opposite ends of the bottom support 1, the spacing of the support limiting frames 2 being adjustable; a plurality of support frames 3 detachably connected to the bottom support 1 are provided between the support limiting frames 2; both the support frame 3 and the support limiting frame 2 include a top horizontal brace 22 and a first telescopic member 21, the first telescopic member 21 being used to adjust the height of the top horizontal brace 22 so that the plurality of top horizontal braces 22 are connected to form an arched support structure.

[0026] Typically, the top of the annealing furnace is an arched structure, hereinafter referred to as the arch. The arch has a horizontal span and a vertical span. The two ends of its horizontal span are respectively set on the wall 5 at the bottom of the arch, and its vertical span extends along the length of the wall 5.

[0027] The aforementioned support and limiting frame 2 can fit against the wall 5 at the bottom of the arch and limit the support frame 3 between them. The support and limiting frame 2 is set to an adjustable spacing form, which can be adapted to different wall 5 spacings to be suitable for the construction of annealing furnace roofs of different specifications. The support and limiting frame 2 and the support frame 3 are arranged along the transverse span direction of the arch, and the top horizontal brace 22 is set along the longitudinal span direction of the arch. By setting the support frame 3 to a detachable form, the number of support frames 3 can be selectively set according to the spacing of the support and limiting frame 2, so that the support and limiting frame 2 is fully covered with support frames 3. Then, according to the curvature and height of the arch, the length of the first telescopic member 21 is adjusted, and the height of the support frame 3 and the support and limiting frame 2 corresponding to different positions of the arch is adjusted, so that the two adjacent top horizontal braces 22 have a matching height difference, and finally together they form an arched support structure that matches the shape of the arch, so as to facilitate the masonry work on the top horizontal brace 22 to form the arch. The above technical solution allows for the rapid assembly of masonry arc surfaces based on the transverse span, height, and curvature of the arch, making it applicable to the construction of arches of various specifications. This expands the applicability of the device, facilitates its reuse, and avoids material waste and construction costs. Furthermore, its ease of installation and dismantling improves the operational efficiency of arch construction.

[0028] The cross-sectional shape of the top horizontal brace 22 can be circular, square or other shapes. Preferably, the top horizontal brace 22 is made of a rod with a circular cross-section and has good rigidity, which can better shape the masonry curvature of the arch support structure and provide more uniform support for the masonry of the arch.

[0029] Furthermore, in this embodiment, the bottom support 1 includes a second telescopic member 11, which is used to adjust the width of the bottom support 1; the support limiting frame 2 is disposed opposite to both ends of the bottom support 1 in the width direction, and the support frame 3 is arranged along the width direction of the bottom support 1. By setting the second telescopic member 11, the spacing between the support limiting frames 2 can be adjusted to adapt to the span requirements of different arches; by setting the support frame 3 to be arranged along the width direction of the bottom support 1 and fully distributed between the support limiting frames 2, the limiting effect of the support limiting frames 2 on the support frame 3 can be fully utilized to prevent it from tilting to both sides; the top cross braces 22 on the support frame 3 and the support limiting frame 2 are arranged in parallel, which can easily adjust the height difference between the top cross braces 22 to form a shape that adapts to the arch.

[0030] In the above embodiment, the bottom support also includes a fixing member 12 arranged along its length direction, the fixing member 12 being connected to both ends of the second telescopic member 11; the support limiting frame 2 is fixed to the fixing member 12; the limiting frame is detachably connected to the second telescopic member 11.

[0031] Specifically, the aforementioned fixing member 12 and the second telescopic member 11 are vertically connected to form a stable frame structure. There are two fixing members 12, and the second telescopic member 11 is set between the two fixing members 12. The number of the second telescopic member 11 can be set according to the requirements. By adjusting the length of the second telescopic member 11, the distance between the two fixing members 12 can be adjusted, thereby causing the support limiting frame 2 to move closer or further away from each other to adapt to arches with different lateral spans. By detachably setting the limiting frame on the second telescopic member 11, it is easy to control the number of support frames 3. When the second telescopic member 11 is fully covered with support frames 3, it can be ensured that the space between the two support limiting frames 2 is fully covered with support frames 3.

[0032] Furthermore, in this embodiment, the first telescopic member 21 includes a supporting upright 211 and a sliding groove rod 212 slidably connected to the supporting upright 211. The supporting upright 211 is connected to both ends of the top cross brace 22 and is provided with a limiting member 213, which is used to limit the position of the sliding groove rod 212 on the supporting upright 211. In use, according to the height of the arched top position corresponding to the limiting frame, the sliding groove rod 212 slides relative to the supporting upright 211, driving the top cross brace 22 to move to a set height. Then, the limiting member 213 clamps the sliding groove rod 212, thereby fixing the top cross brace 22 at the set height.

[0033] In one possible technical solution of the above embodiment, the support rod 211 is tubular and sleeved on the sliding rod 212; the outer wall of the support rod 211 is provided with a threaded hole, and the limiting member 213 is threadedly connected to the threaded hole. The support rod 211 has at least one opening, and the outer diameter of the sliding rod 212 is adapted to the inner diameter of the support rod 211, allowing it to slide freely within the cavity of the support rod 211 to change the connection length between the two; preferably, at least two sets of threaded holes are provided near the opening at the end where the support rod 211 connects to the sliding rod 212, and are disposed opposite to each other on the side wall of the support rod 211, each set of threaded holes including multiple threaded holes arranged along the length direction of the support rod 211; in use, by screwing on the limiting member 213, the limiting member 213 abuts against the sliding rod 212 from both sides, thereby clamping the sliding rod 212 and fixing it inside the support rod 211. The structure of the aforementioned support rod 211 and sliding rod 212 is easy to process and manufacture, easy to adjust, and the connection length of the two can be continuously adjusted to meet the requirements for adjusting the height of the top cross brace 22.

[0034] Preferably, the cross-sectional shape of the support rod 211 and the sliding rod 212 is square, which can effectively prevent the sliding rod 212 from deflecting when sliding in the support rod 211; the outer wall of the sliding rod 212 is provided with a groove, the position of the groove corresponding to the position of the threaded hole of the support rod 211, so that the limiting member 213 can extend into the groove and fix the sliding rod 212 more stably in the support rod 211.

[0035] Specifically, the support limiting frame 2 includes a top horizontal brace 22 and a first telescopic member 21. The first telescopic member 21 includes a support upright 211 and a sliding groove rod 212 slidably connected to the support upright 211. The bottom end of the support upright 211 is fixedly connected to the fixing member 12, so that the support limiting frame 2 has a portal structure. In order to further enhance the stability and force performance of the support limiting frame 2, a reinforcing rod is also provided below the top horizontal brace 22. The two ends of the reinforcing rod are connected to the support upright 211. The number of reinforcing rods can be set as needed. In order to avoid the reinforcing rods affecting the sliding of the sliding groove rod 212, the reinforcing rods are preferably set on the support upright 211.

[0036] Furthermore, in this embodiment, the support frame 3 further includes a clamping plate 31, which is disposed opposite to the bottom of the support column 211 for clamping the second telescopic member 11. That is, the support frame 3 includes a top cross brace 22, a first telescopic member 21, and a clamping plate 31. The first telescopic member 21 includes a support column 211 and a sliding rod 212. The clamping plate 31 is disposed opposite to the bottom of the support column 211. The clamping plate 31 has a downward opening, and the spacing between the clamping plates 31 is adapted to the shape of the second telescopic member 11, so that the second telescopic member 11 can be clamped from both sides, thereby fixing the support frame 3 to the second telescopic member 11. By providing the clamping plate 31, it is easier to install and remove the support frame 3.

[0037] Similarly, the support frame 3 has an overall portal frame structure. To improve the stability and load-bearing capacity of the support frame 3, reinforcing rods are also provided on the support uprights 211 of the support frame 3. Preferably, the first telescopic components 21 of both the support frame 3 and the support limiting frame 2 are mass-produced using the same specifications, which makes processing and manufacturing easier, reduces manufacturing costs, and makes it easier to control installation accuracy.

[0038] Further, in this embodiment, the second telescopic member 11 includes a horizontal crossbar 111 and a horizontal sliding rod 112 slidably connected to the horizontal crossbar 111. The horizontal crossbar 111 is provided with a fastener 113, which is used to limit the position of the horizontal sliding rod 112 on the horizontal crossbar 111. One end of the horizontal crossbar 111 is slidably connected to the horizontal sliding rod 112, and the other end is connected to a fixing member 12. The other end of the horizontal sliding rod 112 is connected to another fixing member 12. In use, according to the lateral span of the arch and the distance between the two side walls 5, the horizontal sliding rod 112 slides relative to the horizontal crossbar 111, causing the fixing member 12 to move closer or further away, so that the distance between the two fixing members 12 matches the lateral span of the arch. Then, the horizontal sliding rod 112 is clamped by the fastener 113, thereby fixing the distance between the two fixing members 12 at a set value.

[0039] In this application, the structure of the second telescopic member 11 can be the same as or different from that of the first telescopic member 21, as long as it can achieve the length adjustment function. For example, the structure of the second telescopic member 11 is the same as that of the first telescopic member 21, that is, the horizontal crossbar 111 is tubular and sleeved on the horizontal slide bar 112; the outer wall of the horizontal crossbar 111 is provided with a threaded hole, and the fastener 113 is threaded into the threaded hole. Preferably, both the horizontal crossbar 111 and the horizontal slide bar 112 are made of tubular fittings with a square cross section.

[0040] In this embodiment, the number of second telescopic members 11 is at least two. Both the support limiting frame 2 and the limiting frame are provided with two support uprights 211, which are respectively fixed to the two second telescopic members 11 by clamping plates 31. By setting the cross-section of the second telescopic member 11 to be square, when the clamping plate 31 is clamped on the second telescopic member 11, preferably, the clamping plate 31 is attached to the two sides of the second telescopic member 11, so that the support uprights 211 are more stably fixed on the second telescopic member 11. Alternatively, the distance between the clamping plates 31 is slightly larger than the opposite sides of the second telescopic member 11, and the stable fixing of the support uprights 211 can also be achieved by filling the gap between them with padding.

[0041] In a preferred embodiment, the bottom support 1 is further provided with a support plate 13 for placing construction tools and masonry materials. Specifically, the bottom support 1 has a set length, with the support limiting frame 2 and the support frame 3 located at one end along its length. A plurality of second telescopic members 11 are provided between the fixing members 12 at the other end of the bottom support 1. The support plate 13 is erected on the upper part of the second limiting frame to form a stable support, capable of bearing the construction tools and masonry materials used for arch masonry construction, so that construction personnel can easily access them.

[0042] In the above embodiment, the top horizontal brace 22 has a predetermined length along the length direction of the bottom support 1, which is a part of the longitudinal span of the arch. The arch-shaped support structure formed by the top horizontal brace 22 can be used to construct a portion of the arch corresponding to the length of the top horizontal brace 22. The bottom of the bottom support 1 is also provided with a moving mechanism 4, which can drive the bottom support 1 to move along the longitudinal span of the arch, gradually completing the construction of the arch within the entire longitudinal span. The length of the top horizontal brace 22 can be set as needed and is not limited here.

[0043] Specifically, the moving mechanism 4 uses rollers, which are positioned opposite each other at the bottom of the two fixed parts 12.

[0044] This application also proposes a method for constructing the arch of an annealing furnace, employing the aforementioned support device for constructing the arch of an annealing furnace, such as... Figure 4 As shown, it includes the following steps:

[0045] S1. Adjust the length of the second telescopic component 11 according to the width of the annealing furnace;

[0046] First, assemble the bottom bracket 1 and the support limiting frame 2. Preferably, the two ends of the second telescopic member 11 are welded to the two fixing members 12 respectively, and the support upright 211 of the support limiting frame 2 is welded to one end of the fixing member 12 in the length direction. The width of the annealing furnace is the distance between the two side walls 5 at the bottom of the furnace top. Control the horizontal slide bar 112 to move along the horizontal crossbar 111 until the distance between the outer edges of the two fixing members 12 matches the distance between the walls 5, and lock the horizontal slide bar 112 with fasteners 113.

[0047] S2. Install the support frame 3 onto the second telescopic member 11, and fully cover the space between the support limit frames 2;

[0048] Based on the length of the second telescopic member 11, select an appropriate number of support frames 3, and clamp them onto the second telescopic member 11 using the clamping plates 31 at the bottom of the support frames 3. Padding can be used to ensure that the clamping plates 31 clamp the second telescopic member 11 tightly. Continue until the support frames 3 are fully distributed between the two support limiting frames 2. Preferably, the adjacent support frames 3 are close to each other, so that the adjacent top cross braces 22 are close to each other, or there is a small gap between the adjacent top cross braces 22.

[0049] S3. Move the annealing furnace arch support device into the annealing furnace, and adjust the length of the first telescopic member 21 according to the curvature of the furnace top so that the top horizontal brace 22 is connected to form an arch support structure.

[0050] Preferably, the two fasteners 12 and the support limiting frame 2 are respectively attached to the two side walls 5 to avoid the bottom support 1 from shifting laterally during the operation, which would affect the accuracy of the arch masonry.

[0051] Adjust the first telescopic member 21 on the support limit frame 2 and the support frame 3 one by one. The adjustment can be made in the order from one side to the other or from the middle to both sides. During the adjustment, control the slide bar 212 to move along the support upright 211 until the top of the top cross brace 22 is at the set height. Then lock the slide bar 212 through the limit member 213.

[0052] S4. Carry out the bricklaying work for the furnace top.

[0053] Workers can also place masonry materials and construction tools on the support plate 13. After the masonry of one part of the arch is completed, push the bottom support 1 to move along the length of the annealing furnace to carry out the masonry of the next adjacent part of the arch until the masonry work is completed within the entire longitudinal span of the arch.

[0054] After the arch is constructed, the entire assembly can be disassembled for transportation and storage, reducing site occupation.

[0055] The advantages and positive effects of this utility model are:

[0056] (1) By setting up bottom brackets, support limit frames and support frames, the masonry arc surface can be quickly assembled according to the transverse span, height and curvature of the arch, which reduces the workload and improves construction efficiency.

[0057] (2) By setting an adjustable bottom support and selectively setting the number of support frames, the device can be applied to the construction of arches of various specifications, which expands the scope of application of the device, facilitates its reuse, and avoids material waste and construction costs.

[0058] (3) By setting up a moving mechanism, the device can be easily moved to different parts of the arch for masonry work without repeated installation and dismantling, which saves construction costs and improves construction efficiency.

[0059] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
