Description

Technical Field

[0001] The invention relates to the technical field of ballast cleaning machines, and in particular to a pipe clamp device and a method for fixing a plurality of pipes at a boom of a ballast cleaning machine. Background Art

[0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art.

[0003] The main structure of a traditional excavator can be improved into a ballast cleaning machine. The function of the ballast cleaning machine is to dig out and screen the dirty ballast within a range of 30 to 40 cm deep from the bottom of the rail sleeper, backfill the qualified ballast after screening onto the line, and add some new ballast to form a clean roadbed. In order to achieve this function, the ballast cleaning machine needs to be equipped with more rotary attachment motors, chain attachment motors and gear attachment motors than traditional excavators, which requires several more sets of pipelines on the boom. At present, the boom of traditional excavators has been arranged with quick-change, crushing and hydraulic shear steel pipes. These pipelines are arranged on the outer side of the boom through pipe clamps, and the arrangement space at the boom is limited. With the increase of pipelines, the problem that the increased pipelines cannot be reasonably arranged is that the existing processing method is to fix two adjacent pipelines to the boom through pipe clamps. The pipe clamp can only fix two pipelines at most, and each pipeline has not only an oil inlet pipe but also an oil return pipe. The number of pipelines is large, so layer after layer of pipelines are arranged in turn on the outside of the already arranged pipelines. This installation method has the problem of inconvenient disassembly and assembly, that is, if the inner pipeline has a problem and needs to be replaced, the outer pipeline needs to be removed before the inner pipeline can be removed, which makes the maintenance of the ballast cleaning machine more complicated.

[0004] In addition, some pipelines are thinner, some are thicker, and all pipelines are laid on the outside of the boom, resulting in a rather chaotic layout. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a pipe clamp device for fixing multiple pipes at a boom of a ballast remover, which can fix multiple pipes at the boom and facilitate the disassembly of the pipes.

[0038] In a typical embodiment of the present invention, reference is made to Figure 1 and Figure 2 As shown, a pipe clamp device for fixing multiple pipes at the boom of a ballast cleaning machine includes a first pipe clamp 1 and a second pipe clamp 2. The first pipe clamp 1 is provided with at least one layer from the outer side of the boom outward. When the first pipe clamp 1 is provided with two or more layers, two adjacent first pipe clamps 1 are fixedly connected. The first pipe clamp 1 is fixed to the surface of the boom by welding.

[0042] In this embodiment, the length of the support ring 1 - 2 is smaller than the width of the first tube base 1 - 1 .

[0043] Of course, in other examples, the first tube base 1 - 1 may also be provided with two partitions 1 - 4 , and the two partitions 1 - 4 may separate the three support rings 1 - 2 .

[0044] It should be noted that when the first pipe clamp 1 is provided with two or more layers, the two adjacent first pipe clamps 1 are staggered, and the first cover plate 1-3 of the first pipe clamp of the lower layer (the first pipe clamp close to the boom) is arranged in the direction of the center line of the length direction of the boom, and the first pipe clamp located on the upper layer is arranged close to the second pipe clamp 2, and the second pipe clamp 2 is located on the outside of the center line of the length direction of the boom, so as to avoid the pipeline 3 from being accumulated in the middle position of the boom, facilitate the fixation of the pipeline 3 from the outside through the second pipe clamp 2, and will not interfere with the pipeline on the inside. The staggered first pipe clamps are also conducive to the identification of the pipeline 3.

[0045] refer to Figure 2 As shown, when the first pipe clamp 1 is provided with two or more layers, the length of the first pipe clamp located in the upper layer is smaller than the length of the first pipe clamp located in the lower layer, the structure of the first pipe clamp located in the upper layer is the same as or different from the structure of the first pipe clamp located in the lower layer, the first pipe clamp located in the upper layer can be used to fix the pipe with a smaller diameter, and the first pipe clamp located in the lower layer can be used to fix the pipe with a larger diameter. When the first pipe clamp structures are the same, the pipes of the same specification are fixed by the first pipe clamp.

[0046] The first pipe clamp 1 located at the lower layer includes a first pipe seat 1-1, which is connected to the second pipe clamp 2. The first pipe seat 1-1 supports the partition, and support rings are arranged on both sides of the partition 1-4 for the pipeline to pass through.

In addition, when the support ring is a whole circular ring component, the pipeline 3 is provided through the first pipe clamp 1. During processing, the support plate has been connected to the first pipe clamp of the lower layer, and the end of the support plate is also connected to the second pipe clamp to ensure the overall stability. In this way, after the upper first pipe clamp supports the upper pipeline on site, the third cover plate 1-7 can be installed.

[0049] In other examples, because the end of the pipeline cannot pass through the support ring, the support ring 1-2 is not a complete support ring. A part of the support ring (half ring) is fixed to the first pipe seat 1-1, and the first pipe seat 1-1 is a flat plate. The other part of the support ring is fixed to the inner side of the first cover plate 1-3. The first cover plate is buckled on the first pipe seat 1-1 to achieve buckling. The two adjacent layers of first pipe clamps 1 are installed on site. The first cover plate 1-3 is provided with a countersunk hole 1-8, and the top of the countersunk hole 1-8 is a threaded hole.
