Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixing device technology, and in particular to a multi-way oil pipe fixing device. Background Technology
[0002] In the power systems of large mechanical equipment, the reliable fixing of multiple oil pipes, such as fuel pipes, lubrication pipes, and hydraulic pipes, is crucial. These oil pipes usually need to be densely arranged in a limited space. To ensure the fixing of the oil pipes, a main support made of angle steel and thick flat steel is usually used, and bolts are used to fix the pipe clamps on one side. The toughness of the plate material is used to clamp the oil pipes, thereby fixing them and improving stability.
[0003] Large mechanical equipment generates severe vibrations during operation. Traditional pipe clamps are insufficient to support the tightness of oil pipes, resulting in severe shaking of the oil pipes under vibration transmission. This not only accelerates pipe fatigue but also directly causes sealing failure and leakage at oil pipe joints, leading to oil waste, environmental pollution, and in severe cases, even affecting the safe operation of the main unit and increasing maintenance costs. Therefore, a multi-way oil pipe fixing device is proposed to solve the above problems. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a multi-channel oil pipe fixing device, which aims to improve the problem of insufficient pipe clamp fastening effect in the prior art, which easily leads to frequent oil leakage at the oil pipe connection.

An mounting plate is fixedly connected to the outer side of the common rail unit housing. A fastening assembly is installed between the mounting plate and the bracket. Pipe clamps are slidably connected to both the front and rear sides of each pipe. A bolt is slidably connected to the middle of one of the pipe clamps. The other end of the bolt passes through the bracket and another pipe clamp from back to front. A nut is threaded onto the outer circumference of the bolt. A groove is formed on the side of each pipe clamp near the bracket, and the pipe is located in the middle of the groove.
[0007] The fastening assembly includes a second bolt, which is slidably connected to the middle of the bracket, and the other end of the bracket passes through the mounting plate. A second nut is threaded onto the outer circumference of the second bolt.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Reference Figures 1-3 This utility model provides an embodiment of a multi-channel oil pipe fixing device, including a common rail unit housing 1, a bracket 3, and pipe clamps 6. Multiple pipes 5 are installed in the middle of the common rail unit housing 1. A mounting plate 2 is fixedly connected to the outer side of the common rail unit housing 1. A fastening assembly is installed between the mounting plate 2 and the bracket 3. Pipe clamps 6 are slidably connected to both the front and rear sides of the pipes 5. A bolt 7 is slidably connected to the middle of one of the pipe clamps 6. The other end of the bolt 7 passes through the bracket 3 and another pipe clamp 6 sequentially from back to front. A nut 8 is threaded onto the outer periphery of the bolt 7. Grooves 9 are provided on the side of each pipe clamp 6 near the bracket 3. The pipes 5 are located in the middle of the grooves 9. The fastening assembly includes a bolt 10, which is slidably connected to the middle of the bracket 3. The other end of the bracket 3 passes through the mounting plate 2. A nut 11 is threaded onto the outer periphery of the bolt 10. Multiple pipes 5 are located on the left and right sides of the bracket 3, respectively. The distance between the center of the groove 9 and the edge of the pipe clamp 6 is less than the diameter of the pipe clamp 6. First, using bolt 10 and nut 11, the bracket 3 can be fixed to the mounting plate 2 on the outside of the common rail unit box 1, so that the bracket 3 can pass through between multiple pipes 5. Then, two pipe clamps 6 are attached to the pipes 5 on both sides and aligned with the bracket 3, so that bolt 7 and nut 8 can fix the pipe clamps 6, pipes 5 and bracket 3. At the same time, since the distance between the center of the groove 9 and the edge of the pipe clamp 6 is less than the diameter of the pipe clamp 6, when the pipe 5 is tightened, the pipe 5 can be completely fixed in the groove 9 of the pipe clamp 6, so that the bracket 3, pipe clamp 6 and pipe 5 form a whole, thereby improving the tightening effect of the pipe 5, avoiding violent shaking of the pipe 5 and preventing leakage at the connection.
[0029] Reference Figure 2 Flat steel 4 is installed on the side of each pipe clamp 6 away from the bracket 3. A washer 12 is slidably connected to the outer periphery of the bolt 2 10, and the washer 12 is located between the bolt 2 10 and the bracket 3. The flat steel 4 can improve the structural strength of the pipe clamp 6, thereby preventing the pipe clamp 6 from loosening between the pipe clamp 6 and the pipe body 5 due to deformation.
[0030] Reference Figure 2Both pipe clamps 6 are made of aluminum alloy, while the bracket 3 and flat steel 4 are made of Q235 steel plate. The toughness of the aluminum alloy pipe clamps 6 can improve the fit between the pipe clamps 6 and the pipe body 5, while the Q235 steel plate brackets 3 and flat steel 4 can improve the overall structural strength of the fixing device, thereby preventing deformation of the brackets 3 and pipe clamps 6.
[0031] Working principle: The bracket 3 is fixed to the outside of the mounting plate 2 by bolt 10 and nut 11, so that the bracket 3 passes through the multiple pipes 5. Then, bolt 7 and nut 8 are used to clamp the multiple pipes 5 to the outside of the bracket 3 by two pipe clamps 6, so that the pipes 5 are located in the middle of the groove 9. Thus, the multiple pipes 5, the bracket 3 and the pipe clamps 6 form a whole, thereby improving the fastening strength of the pipes 5, avoiding violent shaking of the oil pipes, preventing leakage at the connection, ensuring safe operation of the main unit and reducing maintenance costs.
[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
