Abstract
Description
Technical Field
[0001] This utility model relates to the fixing of pipelines on engineering machinery, specifically to a pipeline tightening and path guiding structure. Background Technology
[0002] Construction machinery is equipped with various pipelines, such as cables, signal cables, liquid hoses, and gas hoses. Because construction machinery frequently extends, retracts, and rotates during operation, the pipelines installed on it also extend, retract, and rotate synchronously. Therefore, the pipelines are usually designed to be long. If the pipelines are in a slack state during synchronous extension, retraction, and rotation, they are very prone to tangling or even breakage.
[0003] Common pipeline installation methods in the prior art involve securing the pipeline along its path with multiple pipe clamps or binding it to an associated structure with cable ties. These common methods either only secure the pipeline's path or allow the pipeline to rotate without securing it. However, these common methods in the prior art cannot achieve pipeline tension while ensuring the pipeline's path is determined, thus preventing the pipeline from becoming slack. Utility Model Content
[0004] The technical problem to be solved by this utility model is that, in view of the shortcomings of existing pipeline installation brackets in that they cannot achieve pipeline tensioning, this utility model provides a pipeline tightening and path guiding structure that can both fix the pipeline and tension the pipeline.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A pipeline tightening and path guiding structure includes an installation plane, on which a first pipeline clamp and a second pipeline clamp are sequentially installed along the pipeline installation path. Its structural features are as follows: A sliding rail is provided between the first pipe clamp and the second pipe clamp. A pipe carrier is slidably installed on the sliding rail. A pipe channel is provided on the pipe carrier for the pipe to pass through. One end of the first elastic member is connected to the side of the pipe carrier near the first pipe clamp. The other end of the first elastic member is connected to the first pipe clamp or a mounting plane near the first pipe clamp. One end of the second elastic member is connected to the side of the pipe carrier near the second pipe clamp. The other end of the second elastic member is connected to the second pipe clamp or a mounting plane near the second pipe clamp. The elastic force of the first elastic member and the second elastic member is less than the lateral thrust when the pipe is straightened. In the initial state, the first elastic element and the second elastic element maintain their natural lengths, and the axes of the first elastic element and the second elastic element are perpendicular to the sliding track. After the pipeline is installed, the first elastic element and the second elastic element are tensioned respectively, and the axes of the first elastic element and the second elastic element form an angle of less than 90 degrees with the sliding track respectively. The pipeline is tightened under the elastic force of the first elastic element and the second elastic element.
[0006] A further improvement to the above scheme is that the first pipeline clamp and the second pipeline clamp are both rotatable pipeline clamps.
[0007] A further improvement to the above scheme is that the sliding track includes a square tube installed on the mounting plane and a strip groove arranged along the axial direction of the square tube, and a rotating shaft is installed in the middle of the pipeline carrier, and the rotating shaft is slidably installed in the strip groove.
[0008] A further improvement to the above scheme is that the pipeline carrier is a turntable, the turntable includes a first disc body and a second disc body, the middle part of the first disc body and the middle part of the second disc body are connected as one unit, and the pipeline channel is left between the first disc body and the second disc body.
[0009] A further improvement to the above solution is that a limiting device is installed on the outside of the pipeline channel.
[0010] A further improvement to the above scheme is that the center plane of the pipeline channel of the pipeline carrier is located on the same plane as the center plane of the pipeline channel of the first pipeline clamp and the second pipeline clamp.
[0011] A further improvement to the above scheme is that the pipeline carrier is a rotary pipeline clamp.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1) This utility model can use the elastic force of the first and second elastic elements to push the pipeline carrier to move in the direction of tensioning the pipeline, thereby achieving pipeline tensioning. Alternatively, it can use the tension applied by the components connected to the pipeline to overcome the elastic force of the first and second elastic elements and drive the pipeline carrier to move in the direction of releasing the pipeline, thereby achieving pipeline release. In other words, the structure of this utility model can enable the pipeline to be tensioned and released while ensuring that the pipeline's path is determined, thus facilitating the rotation of the pipeline.
[0013] 2) The first and second pipeline clamps and pipeline carrier of this utility model can rotate on their own and have no solidification points, so that the pipeline will not be blocked due to excessively small turning angle or pipeline bending due to amplitude change / rotation and other actions.
[0014] 3) The pipeline channels of the first and second pipeline clamps and pipeline carrier of this utility model can fix the range of movement of the pipeline, so that the pipeline can only move along the installation plane within the range of movement and will not move in the direction perpendicular to the installation plane, thus avoiding interference with other structural components or being caught by other structural components and causing damage.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0023] Please see Figure 1 , Figure 2An embodiment of the pipeline tightening and path guiding structure of this utility model includes an installation plane 1. A first pipeline clamp 5 and a second pipeline clamp 7 are sequentially installed on the installation plane 1 along the pipeline installation path. A sliding rail 6 is provided between the first pipeline clamp 5 and the second pipeline clamp 7. A pipeline carrier 2 is slidably installed on the sliding rail 6. A pipeline channel 23 is provided on the pipeline carrier 2 for the pipeline 4 to pass through. One end of a first elastic member 3 is connected to the side of the pipeline carrier 2 near the first pipeline clamp. The other end of the first elastic member 3 is connected to the first pipeline clamp 5 or the installation plane 1 near the first pipeline clamp 5. One end of a second elastic member 8 is connected to the side of the pipeline carrier 2 near the second pipeline clamp. The other end of the second elastic member 8 is connected to the second pipeline clamp 7 or the installation plane 1 near the second pipeline clamp 7. The elastic force of the first elastic member 3 and the second elastic member 8 is less than the lateral thrust on the pipeline carrier 2 when the pipeline 4 is straightened. In the initial state, the first elastic element 3 and the second elastic element 8 maintain their natural lengths, and the axes of the first elastic element 3 and the second elastic element 8 are perpendicular to the sliding track 6. After the pipeline 4 is installed, the first elastic element 3 and the second elastic element 8 are tensioned respectively, and the axes of the first elastic element 3 and the second elastic element 8 form an angle of less than 90 degrees with the sliding track 6 respectively. The pipeline 4 is tightened under the elastic force of the first elastic element 3 and the second elastic element 8.
[0024] The first pipe clamp 5 and the second pipe clamp 7 are preferably rotatable pipe clamps, and the pipe carrier 2 is preferably a rotatable pipe carrier. In this way, when the pipe 4 is tensioned, the first pipe clamp 5, the pipe carrier 2, and the second pipe clamp 7 will not have any solidification points, so that the pipe 4 will not be blocked due to excessively small turning angles or pipe bending caused by amplitude changes / rotation.
[0025] In this embodiment, the sliding track 6 includes a square tube 61 mounted on the mounting plane 1 and a strip groove 62 (preferably an oblong groove, not shown in the figure) arranged axially along the square tube 61. Correspondingly, a rotating shaft 24 is installed in the middle of the pipeline carrier 2. The rotating shaft 24 is slidably installed in the strip groove 62. The pipeline carrier 2 moves with the pipeline 4 by sliding the rotating shaft 24 along the length direction of the strip groove 62 to achieve tension. Obviously, the sliding track 6 of this utility model can also be a strip groove directly formed on the mounting plane 1, or a protruding track directly provided on the mounting plane 1 or the square tube. Correspondingly, a sliding groove can also be provided in the middle of the pipeline carrier 2 to slide and connect with the protruding track to achieve the movement of the pipeline carrier 2.
[0026] In this embodiment, the pipeline carrier 2 is a turntable, which includes a first disc body 21 and a second disc body 22. The middle part of the first disc body 21 and the middle part of the second disc body 22 are connected as one unit, and the pipeline channel 23 is left between the first disc body 21 and the second disc body 22.
[0027] To ensure that the pipeline 4 moves parallel to the installation plane 1, a limiting device 25 is installed on the outside of the pipeline channel 23.
[0028] To ensure that pipeline 4 is installed flat, the center plane of the pipeline channel of the pipeline carrier 2 is on the same plane as the center plane of the pipeline channel of the first pipeline clamp 5 and the second pipeline clamp 7.
[0029] The pipeline carrier 2 is not limited to a turntable; a rotating pipeline clamp can also be used.
[0030] The first elastic element 3 and the second elastic element 8 are preferably springs, but are not limited to this. For example, elastic bands, elastic ropes, etc. can also be used.
[0031] When using this utility model, such as Figure 3 As shown, the first pipe clamp 5 is used to fix the pipe 4 upstream of the pipe carrier 2, and the second pipe clamp 7 is used to fix the pipe 4 downstream of the pipe carrier 2. That is, after the pipe 4 is connected from the previous component, it passes through the first pipe clamp 5 and enters the pipe channel 24 of the pipe carrier 2, and is tangent to the bottom of the pipe channel 24 (the middle of the turntable). Then it passes through the second pipe clamp 7 and connects to the next component. After the pipe 4 is installed, the spring force of the first and second elastic elements 3 and 8 pushes the pipe carrier 2 to the left, thereby pushing the pipe 4 which is in tangential contact with the pipe carrier 2, causing the pipe 4 to bend / fold (when the stroke of the pipe carrier 2 is long enough, the pipe 4 can be folded). This makes the pipe 4 tensioned by the pipe carrier 2. Due to the action of the limiting device 25 during the tensioning process, the pipe 4 can only move in a plane parallel to the mounting plane 1 and cannot move in a direction perpendicular to the mounting plane 1. Finally, the pipe 4 is arranged in an orderly manner in the pipe channel 23 of the pipe carrier 2.
[0032] Since pipeline 4 moves along with pipeline carrier 2, when pipeline 4 moves to the right with the components, the tension of the components will counteract the elastic forces of the first and second elastic elements 3 and 8, causing pipeline 4 to push pipeline carrier 2 to the right. This results in the first and second elastic elements 3 and 8 being stretched, and the length of pipeline 4 that was contracted by pipeline carrier 2 is released again. Figure 4 As shown, the direction of movement of pipeline 4 is restricted by pipeline carrier 2.
[0033] Therefore, this invention can achieve the desired length of the retractable / releasing pipeline 4 while restricting the direction of movement of the pipeline 4.
[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments with equivalent changes, without departing from the scope of the technical solution of this utility model. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the content of the technical solution of this utility model should fall within the protection scope of the technical solution of this utility model.
