Description

Technical Field

[0001] This utility model belongs to the field of hydraulic pipeline fixing technology, and in particular relates to a hydraulic pipeline stabilizing clamp. Background Technology

[0002] Hydraulic pipeline vibration problems are usually caused by fluid pulsation, mechanical vibration or external excitation. The design and installation of pipeline fixing devices are one of the key measures to suppress vibration.

[0003] Currently, the outer diameter of hydraulic pipes used in different scenarios on hydraulic machinery and equipment varies. Therefore, pipe fixing devices for fixing hydraulic pipes need to be customized. Fixed-size pipe fixing devices can only clamp and fix hydraulic pipes of fixed size, resulting in low versatility.

[0004] Secondly, excessive pressure impact can cause hydraulic pipelines to vibrate, leading to frequent pipe cracking, loose joints, and significant hydraulic oil loss. Therefore, when using pipeline fixing devices, elastic washers are usually installed at a location with strong vibration to tighten the pipes. Traditional single-point clamping and fixing methods will gradually fail over time, and the vibration suppression effect of hydraulic pipelines is not significant enough. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] Example

[0037] like Figures 1 to 13 As shown, a hydraulic pipeline stabilizing clamp includes two detachably connected pressure blocks. An annular washer groove is provided in the middle of each pressure block, and annular through grooves are provided on both sides of the washer groove. The inner diameter of the washer groove is larger than the inner diameter of the through groove, and the inner diameter of the through groove also needs to be large enough to ensure that hydraulic pipes 8 of various outer diameters can pass through the through groove. The hydraulic pipes 8 are inserted inside the through grooves. Two washer assemblies are fitted onto the hydraulic pipes 8, and the washer assemblies are respectively set tightly against the inner walls of the washer grooves on both sides, with a gap between the two washer assemblies. Two abutment mechanisms are symmetrically arranged inside one of the pressure blocks. The abutment mechanisms can move axially along the hydraulic pipe 8 and abut against the side walls of the washer assemblies. By moving the abutment mechanisms laterally, the washer assemblies are driven to move, so that the washer assemblies are pressed tightly against the side walls of the washer groove, thus limiting and fixing them.

[0038] In this invention, by setting gasket assemblies with various inner diameter specifications inside the two pressure blocks, eight hydraulic pipes with different outer diameters can be clamped and fixed, which is highly versatile and can be adapted to various scenarios.

[0039] In this invention, two washer assemblies are spaced apart along the length of the pressure block, i.e., along the length of the 8 hydraulic pipes. Two abutting mechanisms are symmetrically arranged inside the pressure block. These mechanisms can move axially along the hydraulic pipes 8 and abut against the side walls of the washer assemblies, driving the washer assemblies to be positioned on both sides of the pressure block, thus limiting and fixing the washer assemblies and preventing them from shifting. This clamping and fixing structure divides the clamping at the vibration point into two sections, using the washer assemblies on both sides inside the pressure block to achieve stable clamping. Furthermore, this method eliminates the need for washer assemblies throughout the entire length of the pressure block, reducing material waste. Compared to traditional single-point clamping and fixing methods, this method can achieve stable fixing over a long period, enhancing the suppression of vibration in the 8 hydraulic pipes.

[0040] like Figures 3-5 , Figure 12 and Figure 13 As shown, the gasket assembly includes a first gasket 6 and a second gasket 7 that can be spliced ​​into a ring structure. The first gasket 6 and the second gasket 7 are spliced ​​together and fitted onto the hydraulic pipe 8 for easy assembly and disassembly.

[0041] Furthermore, the first washer 6 has a first inclined surface 61 on both sides, and the second washer 7 has a second inclined surface 71 on both sides, with the first inclined surface 61 and the second inclined surface 71 fitting together. This structure facilitates the positioning and installation of the washer assembly.

[0042] In this invention, the pressure block includes an upper pressure block 2 and a lower pressure block 1, which are connected by bolts 9. An abutment mechanism is provided on the upper pressure block 2. Specifically, the upper pressure block 2 has a first through hole 23 around its perimeter, and the lower pressure block 1 has a second through hole 13 around its perimeter. When the upper pressure block 2 and the lower pressure block 1 are assembled, the first through hole 23 and the second through hole 13 are aligned, and the bolts 9 are inserted to achieve connection.

[0043] The upper pressure block 2 has a first washer groove 21 in the middle, and first through grooves 22 on both sides of the first washer groove 21; the lower pressure block 1 has a second washer groove 11 in the middle, and second through grooves 12 on both sides of the second washer groove 11. By splicing the upper pressure block 2 and the lower pressure block 1, an annular washer groove and through groove structure are formed inside.

[0044] like Figures 1 to 13As shown, the upper end of the upper pressure block 2 has a sliding groove 24 communicating with the first washer groove 21. The abutment mechanism includes an arc-shaped abutment block 3. The upper end of the abutment block 3 is provided with a sliding part 32, and sliders 33 are respectively provided on both sides of the sliding part 32. The sliding part 32 is slidably disposed in the sliding groove 24, and the sliders 33 slide close to the upper end surface of the upper pressure block 2. The abutment block 3 can move along the sliding groove 24 and abut against the washer assembly. This structure realizes the sliding installation of the abutment block 3. By sliding the abutment block 3, the movement of the abutment block 3 in the first washer groove 21 can be controlled, thereby moving the washer assembly in the first washer groove 21.

[0045] like Figures 3-5 As shown, the first washer 6 is positioned on the upper side of the hydraulic pipe 8, and the second washer 7 is positioned on the lower side of the hydraulic pipe 8. The abutting block 3 abuts against the first washer 6. The movement of the abutting block 3 drives the first washer 6 to move, and the first washer 6 moves synchronously with the second washer 7, so that the first washer 6 is tightly fitted against the side wall of the first washer groove 21, and the second washer 7 is tightly fitted against the side wall of the second washer groove 11. By utilizing the first inclined surface 61 on the first washer 6 and the second inclined surface 71 on the second washer 7, the abutting mechanism drives the first washer 6 and the second washer 7 to move, thereby achieving the limiting and fixing of the washer assembly.

[0046] according to Figures 3-5 When the abutting mechanism moves to both ends of the hydraulic pipe 8, it drives the gasket assemblies (first gasket 6 and second gasket 7) on both sides to move and press against both sides of the pressure block, thereby limiting and fixing the gasket assemblies. In this way, the hydraulic pipe 8 can be stably fixed from both sides, and the gasket assemblies will not shift axially during the continuous fixing process.

[0047] Furthermore, a limiting ring 62 is provided on one side of the first washer 6, and a support ring 31 is provided on one side of the abutment block 3. The inner wall of the limiting ring 62 is closely attached to the outer wall of the support ring 31. Using the support ring 31, the two first washers 6 can be respectively limited and fixed in the first washer groove 21 of the upper pressure block 2, realizing quick assembly and disassembly.

[0048] Furthermore, an adjusting screw 5 is hinged to the sliding part 32. Specifically, a hinge block 51 is provided at the end of the adjusting screw 5, and a rotating shaft 52 is provided inside the hinge block 51. The rotating shaft 52 is rotatably disposed in the shaft hole 34 of the sliding part 32. Fixing blocks 25 are symmetrically arranged on both sides of the upper pressure block 2. The fixing blocks 25 are disposed on both sides of the slide groove 24, and a U-shaped clearance groove 26 is provided on the fixing blocks 25. An adjusting nut 53 is threaded onto the adjusting screw 5. The adjusting screw 5 can rotate and is disposed in the clearance groove 26. One side of the adjusting nut 53 is tightly attached to the side wall of the fixing block 25. By rotating the adjusting nut 53, the movement of the abutment block 3 can be achieved.

[0049] Furthermore, a limiting groove 27 is provided on the outer side of the fixing block 25, and the limiting groove 27 is located on the outer side of the clearance groove 26. A positioning ring 54 is provided on one side of the adjusting nut 53, and the positioning ring 54 is located in the limiting groove 27. This design further limits the positioning of the adjusting nut 53. After the adjusting nut 53 is tightened and fixed, the adjusting screw 5 is completely fixed by the cooperation of the positioning ring 54 and the limiting groove 27, and cannot disengage from the clearance groove 26 or shift within the clearance groove 26.

[0050] In this utility model, a connecting seat 14 is provided on one side of the lower pressing block 1. The connecting seat 14 has several strip-shaped connecting grooves 15, and the upper pressing block 2 and the lower pressing block 1 are connected and fixed by the connecting seat 14.

[0051] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
