[0050] Example

[0051] Please see Figures 1-6 As shown, the present invention provides a technical solution: a hydraulic pipeline fixing and guiding device for engineering machinery, comprising:

[0052] Fixed plate 1 is used to support hydraulic lines;

[0053] The pipeline fixing mechanism includes a guide cylinder 201 arranged on the fixing plate 1 for limiting the hydraulic pipeline;

[0054] The guide locking structure includes a spur gear 301 installed at the bottom of the guide cylinder 201 for fixing the adjusted guide cylinder 201, and the spur gear 301 is meshed in the gear groove opened on the fixing plate 1.

[0055] The protective component includes a cover plate 401 disposed on the fixed plate 1, and one end of the cover plate 401 is bolted to the fixed plate 1;

[0056] The splicing assembly is used to splice multiple sets of fixed plates 1 as needed.

[0057] It should be noted that, with the fixed plate 1 as the basic support, the hydraulic pipeline is limited by the pipeline fixing mechanism, the guide cylinder 201 is positioned at an angle by the guide locking structure, the protective components provide overall protection, and the splicing components enable the expansion of multiple fixed plates 1 to form a complete fixed guide system. It has a high degree of integration, combining fixing, guiding, locking, protection and splicing into one, and is suitable for complex pipeline layouts of engineering machinery.

[0058] In this embodiment, specifically: the pipeline fixing mechanism further includes: an opening groove 202, which is opened and arranged at one end of the guide cylinder 201, for providing curvature for hydraulic pipelines with different directions; a pressure plate 203, which is arranged inside the guide cylinder 201, for fixing hydraulic pipelines with different diameters; a limiting post 204, which is slidably connected to the guide cylinder 201 and whose lower end is fixed to the pressure plate 203; and a threaded rod 205, which is threadedly connected to the guide cylinder 201 and whose lower end is rotatably connected to the T-shaped groove opened at one end of the pressure plate 203, for driving the pressure plate 203 to move.

[0059] Among them, the end opening groove 202 of the guide cylinder 201 is adapted to the bending direction of the pipeline, the threaded rod 205 drives the pressure plate 203 to move up and down to clamp the pipeline, and the limiting column 204 ensures that the pressure plate 203 is stable and does not deflect, realizing reliable clamping of pipelines with different diameters. It can be adapted to pipelines with different diameters and different directions, and the clamping is stable, easy to adjust, and does not damage the pipeline.

[0060] In this embodiment, specifically: the guide cylinder 201 is provided in several groups, and every two groups of guide cylinders 201 cooperate with each other.

[0061] It should also be understood that by using several sets of guide cylinders 201, with each set used in pairs, they can jointly constrain and guide one or more hydraulic lines in both directions, resulting in more uniform clamping and more precise guidance, effectively preventing line deviation, twisting and swerving, and improving fixation stability.

[0062] In this embodiment, specifically: the inner wall of the guide cylinder 201 is provided with a rubber layer, and the lower surface of the pressure plate 203 is provided with a rubber layer.

[0063] In addition, the inner wall of the guide cylinder 201 and the lower surface of the pressure plate 203 are both provided with rubber layers, which make flexible contact with the pipeline, playing a role in anti-slip, shock absorption and buffering, avoiding hard contact wear, reducing vibration and noise, and extending the service life of the pipeline.

[0064] In this embodiment, the guide locking structure further includes: a locking rod 302, which is slidably connected to the fixed plate 1, and one end of the locking rod 302 is engaged with the spur gear 301; a sliding groove 303, which is provided on the fixed plate 1, and the protruding end of the locking rod 302 is slidably connected in the sliding groove 303; and a spring 304, one end of which is connected to the locking rod 302, and the other end of which is connected to the inner wall of the fixed plate 1.

[0065] It should be noted that the spherical gear 301 rotates with the guide cylinder 201, and the spring 304 pushes the locking rod 302 to engage with the spherical gear 301 to achieve angle locking. The locking rod 302 slides along the slide groove 303 to ensure smooth operation. After angle adjustment, it quickly self-locks, the locking is reliable, it does not loosen under strong vibration conditions, and the guiding accuracy is high.

[0066] In this embodiment, specifically: the locking rod 302 is U-shaped, and the locking rod 302 is slidably connected to the upper surface of the protrusion in the slide groove 303, which is provided with locking teeth.

[0067] Among them, the U-shaped locking rod 302 acts on the spur gear 301 at the same time, and the teeth on the protrusion are used to cooperate with the cover plate 401 to achieve secondary limiting. The locking force is balanced, the structure has high strength, and the double locking further improves the reliability of anti-loosening.

[0068] In this embodiment, the protective component further includes: a locking block 402, which is fixedly arranged on the other end of the cover plate 401; a locking groove 403, which is opened and arranged on one end of the fixing plate 1, and the locking block 402 is locked in the locking groove 403; and a toothed groove 404, which is opened and arranged on the cover plate 401, for limiting the locking rod 302, and the locking teeth at one end of the locking rod 302 are engaged in the toothed groove 404.

[0069] It should also be understood that the cover plate 401 is quickly engaged with the slot 403 via the locking block 402, and the toothed groove 404 of the cover plate 401 engages with the locking rod 302, limiting the displacement of the locking rod 302. This provides convenient installation and protective enclosure, achieving a double insurance of gear locking and cover plate 401 limiting, which greatly improves the reliability of the device.

[0070] In this embodiment, the splicing assembly specifically includes: a splicing groove 501, which is formed and arranged on one side of the fixing plate 1; and a splicing block 502, which is fixedly arranged on the other side of the fixing plate 1 and snapped onto the splicing groove 501 on another set of fixing plates 1.

[0071] In addition, the splicing block 502 on one side of the fixed plate 1 and the splicing groove 501 on the other fixed plate 1 engage with each other to achieve rapid splicing between units. The length and number of pipelines can be expanded as needed, and it is suitable for centralized arrangement of multiple hydraulic pipelines, making it highly versatile.

[0072] In this embodiment, specifically: the fixing plate 1 is provided in several groups, and each group of fixing plates 1 has two sets of splicing grooves 501 and splicing blocks 502 on both sides.

[0073] Among them, each of the multiple fixed plates 1 has two sets of splicing grooves 501 and splicing blocks 502 on both sides, which can be freely combined and spliced. The combination is flexible and the arrangement is neat, which can meet the installation requirements of different models and different numbers of pipelines.

[0074] In this embodiment, specifically: both ends of the fixing plate 1 are also connected to bases by bolts, which are used to install the fixing plate 1 on the engineering machinery by bolts.

[0075] It should be noted that the base is connected to both ends of the fixing plate 1, and the whole device is fixed to the frame of the construction machinery by bolts. The installation is firm, the disassembly and assembly are convenient, it is compatible with the installation interface of various construction machinery, and the on-site construction efficiency is high.

[0076] Working principle or structural principle: When in use, the hydraulic pipeline is first placed into the guide cylinder 201. The pressure plate 203 is moved up and down by rotating the threaded rod 205. The guide cylinder 201 works with the inner wall to achieve adaptive clamping and fixing of hydraulic pipelines of different diameters. The limit post 204 ensures that the pressure plate 203 moves smoothly. The rubber layer on the inner side of the guide cylinder 201 and the pressure plate 203 can play a role in anti-slip, shock absorption and anti-wear protection for the pipeline.

[0077] The guide cylinder 201 can rotate in the gear groove on the fixed plate 1 through the bottom spherical gear 301. It can be adapted to hydraulic pipelines with different directions and curvatures by cooperating with the opening groove 202 at the end of the guide cylinder 201. After the angle adjustment is completed, the spring 304 pushes the locking rod 302 to engage with the spherical gear 301 to lock the angle and prevent the guide cylinder 201 from loosening under vibration conditions.

[0078] After installation, cover plate 401 is put on so that the locking block 402 at one end of cover plate 401 engages with the locking groove 403 on the fixing plate 1. At the same time, the toothed groove 404 on cover plate 401 engages with the locking teeth on locking rod 302 to achieve secondary limiting of locking rod 302, further improving the reliability of angle locking and overall protection.

[0079] Multiple sets of fixing plates 1 can be spliced ​​together by interlocking the splicing block 502 on one side and the splicing groove 501 on the other side to meet the layout requirements of multiple hydraulic pipelines. The whole device is fixed to the engineering machinery by the base bolts at both ends of the fixing plate 1, thereby achieving stable, adjustable and reliable fixing and guidance of the hydraulic pipelines.

[0080] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.
