DETAILED DESCRIPTION
[0031] The utility model is further described below in conjunction with the accompanying drawings:
[0032] This embodiment:
[0033] See also Figure 1-5 In this embodiment: a protective sleeve for a hydraulic pipeline connection, the hydraulic pipeline includes a first pipeline 2 and a second pipeline 3, and is characterized in that it includes: a pipeline connector 1, an anti-leakage component and a fastening component.
[0034] In this embodiment, the pipe connector 1 is used to connect the first pipe 2 and the second pipe 3. The pipe connector 1 can be fixed by the combination of bolts and nuts. This is the prior art and will not be elaborated here. The anti-leakage component is used to detect and prevent leakage at the connection. The anti-leakage component includes: a first protective ring 4 and a second protective ring 5. The first protective ring 4 and the second protective ring 5 are connected to form a circular ring, and the circular ring is wrapped around the outer surface of the pipe connector 1.
[0035] In this embodiment, the connection between the first pipeline 2 and the second pipeline 3 is wrapped with an anti-leakage component, thereby preventing the liquid flowing inside the pipeline from leaking. At the same time, when a leak occurs, it can be observed clearly and in time.
[0036] The fastening assembly is arranged on the outer surfaces of the first protective ring 4 and the second protective ring 5, and is used to fasten the first protective ring 4 and the second protective ring 5 together. The first protective ring 4 and the second protective ring 5 can be tightly buckled together through the fastening assembly.
[0037] like Figure 1 and Figure 2 As shown, the anti-leakage assembly further includes: four groups of first blocking members 6 , four groups of second blocking members 7 and four groups of sealing half rings 8 .
[0038] Among them, the two upper groups of first blocking members 6 are located on both sides of the lower part of the first protective ring 4, and the two lower groups of first blocking members 6 are located on both sides of the lower part of the second protective ring 5, and correspond to the two upper groups of first blocking members 6, and the corresponding first blocking members 6 can be connected to form a circular ring; the two upper groups of second blocking members 7 are arranged between the two upper groups of first blocking members 6, and the two lower groups of second blocking members 7 are arranged between the two lower groups of first blocking members 6, and a first groove is formed between the second blocking members 7 and the first blocking members 6; the four groups of sealing semi-rings 8 are all arranged in the first groove, and the second blocking members 7 and the first blocking members 6 are used to fix the sealing semi-rings 8, and the sealing semi-rings 8 are made of wool felt strips, and have the functions of sealing, oil storage, shockproof, sound insulation, heat insulation, anti-static and the like.
[0039] When protection is needed, first place the sealing half ring 8 between the second blocking member 7 and the first blocking member 6; and use the first protective ring 4 and the second protective ring 5 to wrap the pipeline connector 1; so that the pipeline connector 1 is located between the four groups of second blocking members 7, thereby preventing the anti-leakage component from moving; and through the fastening component, the first protective ring 4 and the second protective ring 5 are tightly fitted together; and in this process, since the inner diameter of the sealing half ring 8 is smaller than the inner diameters of the second blocking member 7 and the first blocking member 6, the sealing half ring 8 will be compressed during the fastening process; the sealing half ring 8 will tightly wrap the first pipeline 2 and the second pipeline 3; so that when leakage occurs at the connection, the sealing half ring 8 cooperates with the first protective ring 4 and the second protective ring 5 to prevent liquid leakage; at the same time, since the first protective ring 4 and the second protective ring 5 themselves are transparent, it can be clearly seen whether there is a leak, and maintenance can be carried out in time.
[0040] The inner diameters of the first protection ring 4 and the second protection ring 5 are the same as the inner diameters of the first stopper 6 and the second stopper 7 .
[0041] The four groups of second blocking members 7 are combined to form a second groove, and the second groove is used to wrap the pipe connector 1.
[0042] like Figure 1 and Figure 2 As shown, the fastening assembly includes: a fastening clamp 9, two sets of clamping ears 10, a supporting member 11, a threaded rod 12, a moving member 13, and a knob 14.
[0043] Specifically, two groups of clamping ears 10 are arranged on both sides above the fastening clamp 9, and through holes are respectively opened in the middle of the two groups of clamping ears 10; a support member 11 is arranged in the through hole of one side of the clamping ear 10, and the support member 11 can be disassembled; the threaded rod 12 passes through the corresponding position of the support member 11 and is rotatably connected to the support member 11.
[0044] In this embodiment, the threaded rod 12 also passes through the two sets of clamping ears 10 at the same time, so that the clamping ears 10 will not hinder the rotation of the threaded rod 12.
[0045] The movable member 13 is arranged in the through hole of the clamping ear 10 away from the supporting member 11, and is threadedly connected to the threaded rod 12. When the threaded rod 12 rotates, the movable member 13 will move horizontally, and the movable member 13 will drive the clamping ear 10 on the same side to move, thereby contracting the fastening clamp 9; the knob 14 is fixedly connected to one end of the threaded rod 12 close to the supporting member 11.
[0046] When tightening is required, first put the fastening clamp 9 on the outer surface of the first protective ring 4 and the second protective ring 5; and insert the moving part 13 and the supporting part 11 into the through hole of the clamping ear 10; at the same time, pass the threaded rod 12 through the supporting part 11 and align it with the threaded hole on the moving part 13; then turn the knob 14, and the knob 14 drives the threaded rod 12 to rotate; the threaded rod 12 will cause the moving part 13 to move along the outer wall of the threaded rod 12 toward the direction of the knob 14; the moving part 13 shrinks the fastening clamp 9 through the clamping ear 10 on the same side; and the first protective ring 4 and the second protective ring 5 are tightly fixed together.
[0047] The first protective ring 4 and the second protective ring 5 are made of a transparent material, which may be made of polymethyl methacrylate or other transparent materials.
[0048] Working principle:
[0049] When the protective sleeve for the hydraulic pipeline connection is used, the first pipeline 2 and the second pipeline 3 are first connected together through the pipeline connector 1. When protection is required, the sealing half ring 8 is first placed between the second blocking member 7 and the first blocking member 6; and the first protective ring 4 and the second protective ring 5 are used to wrap the pipeline connector 1; so that the pipeline connector 1 is located between the four groups of second blocking members 7, thereby preventing the anti-leakage component from moving; and through the fastening component, the first protective ring 4 and the second protective ring 5 are tightly fitted together; and in this process, since the inner diameter of the sealing half ring 8 is smaller than the inner diameters of the second blocking member 7 and the first blocking member 6, the sealing half ring 8 will be compressed during the fastening process; the sealing half ring 8 will tightly wrap the first pipeline 2 and the second pipeline 3; so that when leakage occurs at the connection, the sealing half ring 8 cooperates with the first protective ring 4 and the second protective ring 5 to prevent liquid leakage; at the same time, since the first protective ring 4 and the second protective ring 5 themselves are transparent, it can be clearly seen whether there is a leakage, and maintenance can be carried out in time.
[0050] When tightening is required, first put the fastening clamp 9 on the outer surfaces of the first protective ring 4 and the second protective ring 5; and insert the moving part 13 and the supporting part 11 into the through hole of the clamping ear 10; at the same time, pass the threaded rod 12 through the supporting part 11 and align it with the threaded hole on the moving part 13; then turn the knob 14, and the knob 14 drives the threaded rod 12 to rotate; the threaded rod 12 will cause the moving part 13 to move along the outer wall of the threaded rod 12 toward the direction of the knob 14; the moving part 13 shrinks the fastening clamp 9 through the clamping ear 10 on the same side; and the first protective ring 4 and the second protective ring 5 are tightly fixed together.
