[0029] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0030] like Figure 1-Figure 4 As shown, the utility model proposes a temporary fixing device for the attached pipeline 7 during the replacement of the crane beam 3, comprising an existing steel column 4, a steering support 1, a suspension cable 2 and a fixing cable 5; the steering support 1 is arranged on the top of the existing steel column 4, and the existing steel column 4 is used to support the crane beam 3 to be replaced; the suspension cable 2 bypasses at least two steering supports 1 and extends longitudinally along the crane beam 3, and the ends of the suspension cable 2 are respectively connected to the two existing steel columns 4, the suspension cable 2 is parallel to the crane beam 3 and is located in different vertical planes to avoid the crane beam 3 blocking the suspension cable 2; the fixing cable 5 is dispersedly arranged on the suspension cable 2, and is used to connect the pipeline 7 attached to the crane beam 3.

[0031] Among them, the crane is a common equipment used for lifting objects in industrial plants; the crane beam 3 is a load-bearing structure that directly bears the load of the crane, and is usually designed as a simply supported beam, that is, the two ends of the crane beam 3 are fixed to the support, and the support is supported by the existing steel column 4 so that the crane beam 3 has a sufficient height; the pipeline 7 attached to the crane beam 3 includes pipes and cables, etc., and also extends longitudinally along the crane beam 3. The crane beam 3 is provided with a support frame 6 for supporting the pipeline 7.

[0032] The steering support 1 and the crane beam 3 in this embodiment are staggered and arranged on the existing steel column 4 to prevent the installation of the steering support 1 from hindering the removal and replacement of the crane beam 3. The suspension cable 2 between the steering supports 1 is arranged parallel to the longitudinal direction of the crane beam 3. The fixing cable 5 further extends downward to connect with the pipeline 7; through this design, after the crane beam 3 is removed, the pipeline 7 is suspended on the suspension cable 2 through the fixing cable 5, and the gravity of the pipeline 7 is borne by the fixing cable 5 and further transmitted to the suspension cable 2, the steering support 1 and the existing steel column 4, so that the pipeline 7 is firmly fixed in its original position, and will not move or deviate significantly, and will not affect the normal use of the pipeline 7; compared with the prior art in which the pipeline 7 is removed and installed synchronously with the crane beam 3, the process of removing and installing the pipeline 7 is saved, the workload is reduced, the replacement efficiency of the crane beam 3 is improved, and the normal use of the pipeline 7 can be maintained, which is conducive to the normal development of production work; in addition, compared with setting up a bracket on the ground to support the pipeline 7, it does not occupy the ground space, and the normal production operation is guaranteed to the maximum extent.

[0033] In a specific embodiment, the steering support 1 is provided with a connecting portion 101, which extends to the side close to the crane beam 3 to above the pipeline 7, so that the suspension cable 2 is located above the pipeline 7 to be suspended, so as to facilitate fixing the pipeline 7 to its original position through the fixing cable 5 to prevent it from displacement or offset.

[0034] In a specific embodiment, the top surface of the existing steel column 4 has sufficient installation space for installing the steering support 1; the shape of the steering support 1 is designed based on the relative position between it and the pipeline 7, and can be constructed in an L-shape, H-shape, straight shape, etc.

[0035] In some other embodiments, there is insufficient space on the top surface of the existing steel column 4, and the steering support 1 is arranged on the side end surface close to the top of the steel column. Its shape is constructed so that the connecting part 101 is located above the pipeline 7 without affecting the removal of the crane beam 3.

[0036] In this embodiment, the steering support 1 is arranged on the top surface of the existing steel column 4, and its shape is constructed into an L shape. Its bottom end is connected to the existing steel column 4, and its top end extends to the side close to the crane beam 3, and is provided with a connecting portion 101; the crane beam 3 is attached with a pipeline, and the center of the connecting portion 101 is aligned with the center line of the pipeline, so that the suspension cable 2 is aligned with the center line of the pipeline when it is wound around the connecting portion 101, so that the pipeline will not be displaced when it is suspended under the suspension cable 2 through the fixing cable 5.

[0037] In a specific embodiment, the two ends of the cable 2 are respectively connected to the column feet of the existing steel column 4, that is, the extension direction of the cable 2 changes after it bypasses the connecting portion 101. In order to avoid wear on the cable 2, the upper outer contour of the connecting portion 101 is constructed as an arc, and a slot matching the cable 2 is provided. After bypassing the slot, the cable 2 extends downward and is connected to the column foot of the existing steel column 4, so that the cable 2 has better safety performance. At the same time, it is beneficial to adjust the tension of the cable 2 to prevent it from driving the pipeline downward under the action of the gravity of the pipeline.

[0038] Furthermore, the connection part 101 has a set height so that the lowest point of the suspension cable 2 is higher than the pipeline 7. Since the suspension cable 2 mainly bears the downward pulling force, the force balance condition determines that the shape of the suspension cable 2 between the two connection parts 101 is close to a parabola, and the middle part is its lowest point. Therefore, the set height of the connection part 101 should be determined according to the height of the lowest point.

[0039] In this embodiment, the upper part of the fixing cable 5 is connected to the suspension cable 2, and the lower part is connected to the two ends of the support frame 6 of the pipeline 7; that is, the fixing cable 5 is not directly connected to the pipeline 7, but through the support frame 6 connected to the pipeline 7, the support frame 6 is in a force balance state to keep the pipeline 7 in a stable state after the crane beam 3 is removed; the fixing cable 5 connecting the two ends of the same support frame 6 can be one, bypassing the suspension cable 2 and connected to the support frame 6; or it can be two, the upper ends of the two fixing cables 5 are respectively connected to the suspension cable 2, and the lower ends are respectively connected to the support frame 6. Since the suspension cable 2 is parabolic as a whole, the fixing cables 5 connected to different positions of the suspension cable 2 have different lengths, and their lower ends are located at the same height.

[0040] In this embodiment, if Figure 4 As shown, the support frame 6 is in a straight line shape and is vertically supported at the lower end of the pipeline 7. Its length is greater than the width of the pipeline 7 along the horizontal direction of the crane beam 3. After the fixing rope 5 is connected to the support frame 6, the whole is an equilateral triangle. The support frame 6 is arranged parallel to the horizontal plane to keep the pipeline 7 stable.

[0041] In this embodiment, the support frame 6 is set based on the length and weight of the pipeline 7 through force calculation, and the fixing rope 5 and the support frame 6 are set in a one-to-one correspondence, so that the force state of the pipeline 7 does not change during the process of being supported by the support frame 6 and suspended by the fixing rope 5.

[0042] In another specific embodiment, the pipeline 7 is attached to the crane beam 3 by other means, the upper part of the fixing cable 5 is connected to the suspension cable 2, and the lower part is tied and connected to the pipeline 7, so that the pipeline 7 is firmly fixed in its original position;

[0043] In some specific embodiments, in order to achieve stable fixation of the pipeline 7, the lower part of a part of the fixing rope 5 is connected to the two ends of the support frame 6, and the other part of the fixing rope 5 is directly tied and connected to the pipeline 7. The combination of these two methods provides better support for the pipeline 7.

[0044] In a specific embodiment, the suspension cable 2 and / or the fixing cable 5 are made of steel wire ropes. The fixing cable 5 is fixed to the suspension cable 2 through a rope clip. The steel wire rope has sufficient rigidity and tensile strength, and is convenient for installation and connection of the fixing cable 5 and the suspension cable 2.

[0045] In a specific embodiment, the connecting part 101 is made of a disc or a pulley. When the cable 2 is tightened, the connecting part 101 can be driven to rotate, reducing the friction between the cable 2 and the connecting part 101, making it easy to control the tightening and fixing of the cable 2 and avoiding damage to the cable 2.

[0046] The construction method of the temporary fixing device for the attached pipeline 7 during the replacement of the crane beam 3 proposed in the present application specifically comprises the following steps:

[0047] Install the steering support 1 on the top of the existing steel column 4;

[0048] Install the suspension cable 2 so that the suspension cable 2 extends upward from the column foot of an existing steel column 4, passes through at least two steering supports 1, and then connects to the column foot of another existing steel column 4;

[0049] Install the fixing cable 5; the lower part of the fixing cable 5 is connected to both ends of the support frame 6, and the upper part of the fixing cable 5 is connected to the suspension cable 2;

[0050] Cut the support frame 6 to separate the support frame 6 from the crane beam 3;

[0051] Removal and replacement of crane beams 3;

[0052] Welding the support frame 6 to the replaced crane beam 3;

[0053] Remove the fixed cable 5, the suspension cable 2 and the steering support 1 in sequence.

[0054] The advantages and positive effects of the utility model are:

[0055] (1) By installing a steering support on the existing steel column, the pipeline is suspended by a suspension cable and a fixed cable to temporarily fix the pipeline in its original position, avoiding the simultaneous removal of the attached pipeline during the removal and replacement of the crane beam, saving the pipeline removal and installation process, reducing the workload and improving the efficiency of crane beam replacement;

[0056] (2) The installation of the steering support, suspension cable and fixed cable will not affect the removal and replacement of the crane beam. At the same time, compared with setting up a bracket on the ground to support the pipeline, it does not occupy the ground space, thus ensuring the normal operation of production to the greatest extent.

[0057] (3) The pipeline is suspended by suspension cables and fixed cables, the overall force is scientific and reasonable, the connection is stable, and it is easy to install and disassemble, with high safety.

[0058] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
