Description

Technical Field

[0001] The utility model relates to the field of chimneys, in particular to a sleeve chimney installation kit. Background Art

[0002] In the prior art, when installing a sleeve chimney, the inner and outer cylinders must be installed in sequence. During the process, the inner and outer cylinders need to be lifted and installed separately at the same time, which is time-consuming and labor-intensive. Since the inner and outer cylinders are lifted at the same time and lowered in sequence during installation, the installation and positioning are difficult. Summary of the Invention

[0003] Purpose of the utility model: In order to overcome the shortcomings of the background technology, the purpose of the utility model is to disclose a sleeve chimney installation kit.

[0004] Technical solution: The sleeve chimney installation kit disclosed in the utility model comprises an inner cylinder and an outer cylinder of equal length, and circumferential flanges are fixed at both ends of the inner cylinder and the outer cylinder;

[0005] The installation kit includes temporary fixing supports and temporary lifting parts;

[0006] The temporary fixing support comprises one or more fixing rods, which are bolted and fixed to the circumferential flanges of the inner cylinder and the outer cylinder at both ends;

[0007] The temporary lifting parts include multiple flexible connection devices. Temporary lifting ears are fixed on the circumferential flanges at the top of the inner tube and the outer tube respectively. The flexible connection devices are respectively connected to the temporary lifting ears of the inner and outer tubes.

[0008] Furthermore, the circumferential flanges are all outer circumferential flanges.

[0009] Furthermore, the temporary fixing support comprises a cross-bracing structure formed by two intersecting fixing rods, which respectively perform four-point positioning on the circumferential flanges of the inner and outer cylinders.

[0010] Furthermore, three or more temporary lifting ears are evenly spaced circumferentially on the circumferential flange.

[0011] Furthermore, the soft connection device is a chain structure, which is detachably connected to the temporary lifting ears through locks at both ends.

[0012] A sleeve chimney installation process is implemented based on the above-mentioned sleeve chimney installation kit, comprising the following steps:

[0013] S1. After the inner and outer cylinders are assembled, both ends are fixed with temporary support members and transported to the site;

[0014] S2. After unloading, remove the temporary fixed support parts on the top and install temporary lifting parts;

[0015] S3. Remove the connection point between the inner tube and the fixed support, slowly and steadily lift the inner and outer tubes to a vertical position, and remove the connection point between the outer tube and the fixed support;

[0016] S4. Slowly lift the outer cylinder. The inner cylinder gradually emerges as the outer cylinder rises. After being exposed to a certain distance under the traction of the temporary lifting parts, it rises together with the outer cylinder.

[0017] S5. After hoisting in place, the hoisted inner cylinder is connected and fastened with the installed inner cylinder, and then the outer cylinder is controlled to fall. At this time, the temporary hoisting parts are connected in reverse, and the inner and outer cylinders rotate without obstacles, and the hoisted outer cylinder is connected and fastened with the installed outer cylinder;

[0018] S6. Remove temporary lifting parts and recover them for recycling.

[0019] Furthermore, during installation, there is a height difference between the inner and outer tubes at the bottom layer of the chimney, with the inner tube being higher than the outer tube.

[0020] Beneficial effects: Compared with the prior art, the advantages of this utility model are:

[0021] 1. The temporary fixed supports at both ends can ensure that the inner and outer cylinders do not deform during transportation;

[0022] 2. During installation, the entire hoisting process only requires operation on the outer cylinder, saving installation time and costs;

[0023] 3. When lifting the chimney from horizontal to vertical, remove the inner tube support before lifting, and then remove the outer tube support after lifting. This can avoid the downward impact of the inner tube during the lifting process and avoid safety accidents;

[0024] 4. The temporary lifting parts not only realize the embedding of the outer tube into the inner tube before installation, but also realize the pulling of the inner tube onto the outer tube after installation. At the same time, they can be easily dismantled and recycled after installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] like Figure 1 The sleeve chimney installation kit shown in the figure comprises an inner tube 1 and an outer tube 2 of equal length. Both ends of the inner tube 1 and the outer tube 2 are fixed with circumferential flanges 3, and the circumferential flanges 3 are all outer circumferential flanges.

[0029] The installation kit includes temporary fixing supports and temporary lifting parts;

[0030] like Figure 2 As shown, the temporary fixing support comprises one or more fixing rods 4, which are bolted to the circumferential flanges 3 of both the inner and outer cylinders 1 and 2 at both ends. In this embodiment, the temporary fixing support comprises a cross-bracing structure formed by two fixing rods 4 intersecting to provide four-point positioning for the circumferential flanges 3 of the inner and outer cylinders.

[0031] like Figure 3 As shown, the temporary lifting fixture includes multiple flexible connectors 5. Temporary lifting lugs 6 are correspondingly fixed to the circumferential flanges 3 at the tops of the inner and outer tubes 1 and 2. The flexible connectors 5 connect to the temporary lifting lugs 6 of the inner and outer tubes, respectively. Three or more temporary lifting lugs 6 are evenly spaced circumferentially on the circumferential flanges 3. In this embodiment, the flexible connectors 5 are chain-like structures, removably connected to the temporary lifting lugs 6 via locks at both ends.

[0032] A sleeve chimney installation process is implemented based on the above-mentioned sleeve chimney installation kit, comprising the following steps:

[0033] After S1, inner tube 1 and outer tube 2 are assembled, both ends are fixed by temporary fixing supports and transported to the site, which can ensure that the inner and outer tubes are not deformed during transportation.

[0034] S2. After unloading, remove the temporary fixed support parts on the top and install temporary lifting parts.

[0035] S3. Remove the connection point between the inner tube 1 and the fixed support, slowly and steadily lift the inner and outer tubes to a vertical position, and remove the connection point between the outer tube 2 and the fixed support; when lifting the chimney from a horizontal to a vertical state, remove the inner tube support before lifting, and then remove the outer tube support after lifting, so as to avoid the downward impact of the inner tube during the lifting process and avoid safety accidents.

[0036] During installation, there is a height difference between the inner and outer tubes at the bottom layer of the chimney, with the inner tube 1 being higher than the outer tube 2.

[0037] S4. Slowly lift the outer tube 2. The inner tube 1 gradually emerges as the outer tube 2 rises. After being exposed to a certain distance under the traction of the temporary lifting parts, it rises together with the outer tube 2. The distance between the inner tube and the outer tube is designed to be 300-600mm.

[0038] S5. After hoisting in place, the hoisted inner cylinder 1 is connected and fastened with the installed inner cylinder, and then the outer cylinder 2 is controlled to fall. At this time, the temporary hoisting parts are connected in reverse, and the inner and outer cylinders rotate without obstacles. The hoisted outer cylinder 2 is connected and fastened with the installed outer cylinder;
