Description

TECHNICAL FIELD

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

[0003] The main structure of the conventional excavator is improved to form a ballast cleaning machine. The function of the ballast cleaning machine is to excavate and screen the dirty ballast in the range of 30-40 cm deep from the bottom of the rail sleeper, and then backfill the qualified ballast on the track and supplement part of the new ballast to form a clean ballast bed. In order to realize this function, the ballast cleaning machine needs to be equipped with more rotating tool motors, chain tool motors and gear shifting tool motors than the conventional excavator, which requires several sets of pipes to be equipped on the movable arm. However, the movable arm of the conventional excavator is already arranged with quick-change, crushing and hydraulic pipe cutting, and these pipes are arranged on the outer side of the movable arm by pipe clamps. The arrangement space at the movable arm is limited, and with the increase of the pipes, the problem is that the increased pipes cannot be reasonably arranged. The existing treatment method is to fix the two adjacent pipes on the movable arm by pipe clamps, and the pipe clamps can only fix two pipes at most. However, each pipe not only has an oil inlet pipe but also has an oil return pipe, and the number of pipes is relatively large. In this way, one layer of pipes is arranged outside the already arranged pipes, and this installation method has the problem of inconvenient disassembly, that is, if the inner pipe needs to be replaced due to a problem, the outer pipe needs to be removed first, and then the inner pipe can be removed, which makes the maintenance of the ballast cleaning machine more complex.

[0036] As introduced in the background, the existing technology has the problem that the space outside the boom is limited and more pipelines are layered to make the pipelines not easy to be disassembled. In order to solve the above technical problem, the present application provides a pipe clamp device for fixing multiple pipelines at the boom of a ballast cleaner.

[0037] Embodiment one

[0038] In a typical embodiment of the present application, referring to Figure 1 and Figure 2 , a pipe clamp device for fixing multiple pipelines at the boom of a ballast cleaner comprises 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 outside of the boom. When the first pipe clamp 1 is provided with two or more layers, the adjacent two first pipe clamps 1 are fixedly connected. The first pipe clamp 1 is fixed to the surface of the boom by welding. The first pipe clamp 1 is connected with the second pipe clamp 2. The first pipe clamp 1 and the second pipe clamp 2 are spaced apart by 70°-120° to utilize the space outside the boom to install part of the pipelines 3. The second pipe clamp 2 is used to fix at least two pipelines.

[0039] In this embodiment, the first pipe clamp 1 and the second pipe clamp 2 are connected perpendicularly. Of course, the angle between the first pipe clamp and the second pipe clamp can also be 80° or 100°, etc.

[0040] According to actual needs, the first pipe clamp 1 can be provided with one layer. The bottom of the first pipe clamp 1 is welded to the boom. The first pipe clamp 1 can be used to fix two pipelines. The outer end of the first pipe clamp 1 is connected with the second pipe clamp 2. The second pipe clamp is used to fix three pipelines.

[0041] Referring to Figure 1 , the first pipe clamp 1 comprises a first pipe seat 1-1. The first pipe seat 1-1 is connected with the second pipe clamp 2. The outer side of the first pipe seat 1-1 away from the boom supports a partition piece 1-4. The partition piece 1-4 can be a partition block. The partition piece can be welded to the first pipe seat. The two sides of the partition piece 1-4 are provided with support rings 1-2 for the pipelines to pass through. The inner diameter of the support ring is larger than the outer diameter of the pipeline. The two support rings 1-2 are arranged parallel to each other. A first cover plate 1-3 is fixedly connected with the partition piece. The side of the first cover plate 1-3 covers the support ring. The two sides of the first cover plate 1-3 are bent towards the direction of the boom to cooperate with the support ring. The support ring 1-2 and the first pipe seat 1-1 can be welded together.

[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 set 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 set 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, and 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 arrangement of the first pipe clamps is also conducive to the identification of the pipeline 3.

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

[0046] The first pipe clamp 1 located in 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. Support rings are provided on both sides of the partition 1-4 for the pipeline to pass through. The first cover plate 1-3 is detachably connected to the partition. The side of the first cover plate 1-3 covers the support ring 1-2, and the support ring 1-2 is fixedly connected to the first pipe seat 1-1.

[0047] Specifically, the first pipe clamp located on the upper layer includes a support plate 1-6, the support plate 1-6 is fixedly connected to the first pipe clamp of the lower layer, the support plate supports the third cover plate 1-7 and is detachably connected to the third cover plate, a pad 1-5 is provided on the top of the first cover plate 1-3, the pad 1-5 is provided along the width direction of the top of the first cover plate, the pad is provided at the center position of the top of the first cover plate, the pad 1-5 supports the support plate 1-6, a fastener 4 such as a bolt passes through the support plate, the pad is fixedly connected or detachably connected to the first pipe clamp of the lower layer, and the third cover plate 1-7 is provided with at least one first recess on one side facing the support plate to cooperate with the pipeline, specifically two, a spacer block is provided between two adjacent first recesses, and the first recess is an arc-shaped recess;

[0048] It is easy to understand that when the first pipe clamp 1 is provided with multiple layers, the first pipe clamp in the lower layer is connected with the second pipe clamp, and in addition, when the support ring is a whole ring member, the pipe 3 is arranged through the first pipe clamp 1, and the support plate can be connected with the first pipe clamp in the lower layer during machining, and the end of the support plate is also connected with the second pipe clamp, so as to ensure the stability of the whole. Thus, after the upper pipe is supported by the upper first pipe clamp on site, the third cover plate 1-7 can be installed.

[0049] In other examples, because the pipe end cannot pass through the support ring, the support ring 1-2 is not a complete support ring, and a part (half ring) of the support 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, and the first cover plate is buckled on the first pipe seat 1-1 to achieve buckling. The adjacent two layers of first pipe clamps 1 are installed on site. Thus, the first cover plate 1-3 is provided with a counterbore hole 1-8, and the top of the counterbore hole 1-8 is a threaded hole. After the screw passes through the counterbore hole and is connected with the partition piece 1-4, the gasket 1-5 and the support plate 1-6 are installed. The fastener such as a bolt passes through the support plate, the gasket and is inserted into the counterbore hole of the first cover plate.

[0050] It is easy to understand that the width of the support plate 1-6 near the side of the second pipe clamp is smaller than the width of the other side, and the width of the third cover plate 1-7 is smaller than or equal to the width of the narrower side of the support plate.

[0051] Reference Figure 1 and Figure 2 As shown in the drawings, the second pipe clamp includes a second pipe seat 2-1, and the second pipe seat 2-1 is a flat plate. The outer side of the second pipe seat 2-1 away from the first pipe clamp is provided with a second cover plate 2-2. The inner side of the second cover plate 2-2 is provided with multiple second recesses such as two or three to fix the corresponding pipe 3. The interval block is arranged between the adjacent two second recesses. The second recess is an arc-shaped recess. The fastener such as a bolt connects the second cover plate 2-2 and the second pipe seat 2-1.

[0052] The pipe clamp device provided by the embodiment is provided with a first pipe clamp and a second pipe clamp. The first pipe clamp and the second pipe clamp are connected. The first pipe clamp is provided with one layer or more than two layers. The second pipe clamp is connected with the first pipe clamp and is arranged at a certain angle. Thus, the second pipe clamp does not interfere with the installation of the first pipe clamp. In addition, the outer side space other than the outer side of the movable arm can be used to fix part of the pipe. Thus, the pipe is not simply stacked layer by layer. In the limited space, more pipes can be arranged separately. When the pipe is maintained, the corresponding pipe can be easily found and removed or replaced.

[0056] The second pipe clamp 2 is arranged on the side of the first pipe clamp, and part of the pipe is installed by using the space on the outer side of the boom;

[0057] According to the number of pipes to be fixed, the single-layer first pipe clamp or the multi-layer first pipe clamp is selected, the single-layer first pipe clamp can realize the fixation of 5-6 pipes, and the multi-layer first pipe clamp can realize the fixation of 7-8 pipes.

[0058] In some examples, on the opposite sides of the same position on the outer side of the boom, one side is provided with the pipe clamp device with only the single-layer first pipe clamp, and the other side is provided with the pipe clamp device with the two-layer first pipe clamp.

[0059] The above only describes the preferred embodiments of the present application and is not used to limit the present application.
