[0038] In order to solve the problems of the absorption tower pipeline in the prior art, which needs to be matched by multiple workers during disassembly due to the long size or large weight of the pipeline, resulting in low work efficiency, and the use of a crane during replacement of the pipeline of a higher absorption tower is easily affected by the environment such as wind, and there is a great safety hazard in the work process, the utility model provides an absorption tower pipeline replacement supporting device for a cement production system 1, which is different from the mode of using a hoisting machine such as a crane in the prior art, the utility model is provided with a supporting assembly 12 which can provide bottom support for the pipeline during pipeline replacement or after installation is completed, which is beneficial to improve the stability and safety of the pipeline, and the utility model is also provided with an adjusting assembly 11 which is used for mutual cooperation with the supporting assembly 12 to change the relative position of the pipeline and the absorption tower 4, so that the replaced pipeline can be quickly connected with the interface of the absorption tower during installation.

[0039] The utility model provides a kind of absorption tower pipeline replacement supporting device for cement production system 1, as Figure 1 Indicated, the pipeline replacement supporting device 1 includes adjusting assembly 11 and supporting assembly 12.

[0040] Wherein, the absorption tower pipeline 2 (hereinafter referred to as pipeline) is used to connect fan 3 and absorption tower 4 in cement production system, and the absorption tower pipeline 2 includes upper horizontal section 21, vertical section 22 and lower horizontal section 23;The lower horizontal section 23 is horizontally arranged at low position adjacent to the output port of the fan 3, the upper horizontal section 21 is horizontally arranged at high position adjacent to the input port of the absorption tower 4, and the vertical section 22 is perpendicular to the ground, and the top end is connected with the upper horizontal section 21, and the bottom end is connected with the lower horizontal section 23;Absorption tower pipeline 2 is arranged between fan 3 and absorption tower 4 to introduce waste gas generated in cement manufacturing process into absorption tower 4, and the length of upper horizontal section 21 and lower horizontal section 23 is mainly related to the distance from fan 3 to absorption tower 4 in actual production, and the length of vertical section 22 is mainly related to the height of absorption tower 4 interface.

[0041] The adjusting assembly 11 includes linear drive mechanism, and the linear drive mechanism is fixedly connected with the bottom of the low-position supporting assembly 121, so that the low-position supporting assembly 121 can move along the length direction of the linear drive mechanism.The adjusting assembly 11 is arranged at the bottom of the lower horizontal section 23, and includes moving trolley 111, guide rail 112 and adjusting platform 113, as Figure 2As shown, the guide rail 112 is fixedly installed above the adjusting platform 113, the moving trolley 111 is arranged above the guide rail 112, and the bottom of the moving trolley 111 is provided with a rail wheel 111-1 for clamping the guide rail 112, so that the moving trolley 111 can move along the length direction of the guide rail 112. By controlling the moving trolley 111 to move forward and backward on the guide rail 112, the absorption tower pipeline 2 arranged on the top of the adjusting assembly 11 can be driven to move forward and backward, thereby adjusting the front and back positions of the absorption tower pipeline 2 relative to the absorption tower 4, facilitating the mutual butt joint of the pipeline and the absorption tower 4 during the installation process. For example, the length direction of the guide rail 112 can be arranged to point from the fan 3 position to the absorption tower 4 position. When the moving trolley 111 moves forward, the pipeline moves towards the absorption tower 4, and the pipeline and the absorption tower 4 are close to each other. When the moving trolley 111 moves backward, the pipeline moves towards the fan 3, and the pipeline and the absorption tower 4 are away from each other.

[0042] The support assembly 12 includes a low-position support assembly 121 and a high-position support assembly 122. At least one low-position support assembly 121 is arranged at the bottom of the lower cross section 23 for supporting and fixing the lower cross section 23 during disassembly and assembly of the absorption tower pipeline 2. The low-position support assembly 121 is fixedly connected with the moving trolley 111, and the arrangement of the low-position support assembly 121 on the moving trolley 111 can realize the front and back position adjustment and the longitudinal position adjustment of the pipeline. The high-position support assembly 122 is arranged at the bottom of the upper cross section 21 of the absorption tower pipeline 2 for supporting the upper cross section 21 during disassembly and assembly of the absorption tower pipeline 2. The high-position support assembly 122 is fixedly connected with the absorption tower 4. The low-position support assembly 121 and the high-position support assembly 122 of the support assembly 12 can support the upper cross section 21 and the lower cross section 23 of the absorption tower pipeline 2 at different heights, respectively. Compared with the support mode of supporting only one position of the pipeline, supporting multiple positions of the pipeline can improve the stability of the overall structure of the pipeline, which is conducive to keeping the pipeline in a stable state during disassembly and assembly. In addition, the number of low-position support assemblies 121 and moving trolleys 111 can be flexibly increased according to the length of the actual replaced lower cross section 23 of the pipeline, so as to obtain better support effect. For example, for a 2-meter-long lower cross section 23 pipeline, two low-position support assemblies 121 and two corresponding moving trolleys 111 can be arranged. For a 3-meter-long lower cross section 23 pipeline, three low-position support assemblies 121 and three corresponding moving trolleys 111 can be arranged.

For example, the bottom lifting mechanism 121-1 can be arranged as a hydraulic telescopic sleeve, and the telescopic sleeve is driven to extend or shorten by the hydraulic driving part through pressurization or depressurization, so as to adjust the height position of the bottom lifting mechanism 121-1. The bottom lifting mechanism 121-1 can also be arranged as an electric scissor support, and the scissor support is driven to ascend or descend by the motor through forward rotation or reverse rotation, so as to adjust the height position of the bottom lifting mechanism 121-1. The above-mentioned bottom lifting mechanism 121-1 can also be arranged as a mechanism that is adjusted up and down by other ways, but is not limited thereto.
