[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0024] To provide a more complete and detailed description of this disclosure, the following illustrative descriptions of embodiments and examples of the present invention are provided; however, these descriptions are not intended to be the only ways to implement or use the embodiments of the present invention. The embodiments cover features of various embodiments, as well as the method steps and sequences for constructing and operating these embodiments. However, other embodiments may be used to achieve the same or equivalent functionality and sequence of steps.
[0025] The present invention provides a pipeline protection device, comprising a protective sleeve, a keel, an upper cover cross bar and a lower cover cross bar. The protective sleeve comprises an upper cover and a lower cover that can dust-proofly wrap the pipeline. The upper cover and the lower cover are flexible corrugated hoses, which provide the protective sleeve with a curvature not less than a limited curvature facing the upper cover side; keel brackets formed by sequentially connecting a plurality of keel sections are arranged along both sides of the longitudinal direction of the protective sleeve, and a gap exists between the keel bracket and the protective sleeve; a lower cover cross bar is transversely fixed on the crest of the corrugation of the lower cover, and the two ends are movably connected to the keels arranged on both sides of the protective sleeve; the upper cover cross bar is transversely arranged above the upper cover, and the two ends are movably connected to the keels arranged on both sides of the protective sleeve, and there is a gap between the upper cover cross bar and the upper cover; when the protective sleeve bends toward the upper cover side, the keel bracket bends synchronously.
[0026] By adopting the pipeline protection device provided by the present invention, when the protective sleeve moves and bends toward the side of the upper cover, the overhead part is equivalent to the protective sleeve being suspended on the lower cover cross bar, so that the bending degree of the protective sleeve is actually determined by the bending radius of the keel. The bending radius can be smaller, and since there is a gap between the upper cover cross bar and the upper cover, the resistance to the movement of the protective sleeve can be reduced. At the same time, the lower cover cross bar can be used to stabilize the keel, thereby increasing the overhead length.
[0027] Please see Figure 1 and Figure 7 The pipeline protection device provided by the embodiment of the present invention includes a protection sleeve 1, a keel bracket 2, an upper cover cross bar 3 and a lower cover cross bar 4.
[0028] The protective sleeve 1 includes an upper cover 11 and a lower cover 12, which are connected by upper and lower press buckles to form a pipe that can wrap the pipeline in a dust-proof manner. The upper cover 11 and the lower cover 12 are flexible corrugated hoses, which provide the protective sleeve 1 with a curvature not less than a specified value on the side facing the upper cover 11. The corrugated hose is a hose with a corrugated profile formed by alternating crests and troughs. The corrugated profiles of the upper cover 11 and the lower cover 12 are different. In an optional embodiment, the corrugated profiles of the two may also be the same. The press-fit connection between the upper cover 11 and the lower cover 12 is the central axis of the protective sleeve 12, and the central axis is also the movement centerline of the protective sleeve 12.
[0029] Several keel sections are connected in sequence to form a keel bracket 2 , one group of which is provided on each side of the longitudinal direction of the protective sleeve 1 , with a gap between the keel bracket 2 and the protective sleeve 1 .
[0030] A lower cover cross bar 4 is transversely fixed to the crest of the corrugated profile of the lower cover 12, and its two ends are movably connected to the keels placed on both sides of the protective sleeve 1. In an optional embodiment, the lower cover cross bar 4 can be fixedly connected to the crest surface of the corrugated profile of the lower cover 12 by bonding, laminating, riveting, etc. Figure 7The connection between the lower cover crossbar 4 and the lower cover 12 fits tightly. In this embodiment, the cross section of the lower cover 12 is arc-shaped, and an arc-shaped opening space is formed in the middle part of the lower cover crossbar 4. The arc-shaped opening space fits with the arc-shaped wave crest surface in the corrugated profile on the lower cover 12, but the fitting connection between the arc-shaped opening space and the wave crest stops above the connection between the upper cover 11 and the lower cover 12. The upper cover crossbar 3 is placed horizontally above the upper cover 11, and its two ends are movably connected to the keels placed on both sides of the protective sleeve 1, and there is a gap between the upper cover crossbar 3 and the upper cover 11. When the protective sleeve 1 moves, that is, bends toward the side of the upper cover 11, the keel brackets 2 on both sides of the protective sleeve 1 bend synchronously.
[0031] In the pipeline protection device provided by the embodiment of the present invention, when the protective sleeve moves and bends toward the side of the upper cover, the overhead part is equivalent to the protective sleeve being suspended on the lower cover cross bar, so that the bending degree of the protective sleeve is actually determined by the bending radius of the keel. The bending radius can be smaller, and since there is a gap between the upper cover cross bar and the upper cover, the resistance to the movement of the protective sleeve can be reduced. At the same time, the lower cover cross bar cooperates with the keel to stabilize the overhead length.
[0032] Since there are certain differences in the movable connections between the keels in the keel brackets 2 placed on both sides of the protective sleeve 1 and the upper cover cross bar 3 and the lower cover cross bar 4, for the purpose of distinction, the keel placed on one side of the protective sleeve 1 is marked as the first keel 2a, and the keel placed on the opposite side of the protective sleeve 1 is marked as the second keel 2b.
[0033] Please see Figure 2 and Figure 3 Taking the second keel 2b as an example, a first protrusion 21 and a second protrusion 22 are formed along the end edges of the second keel 2b along the connection direction. The first protrusion 21 and the second protrusion 22 are not aligned, and both have slots cc formed on their surfaces. Between adjacent second keels 2b, the second protrusion 22 of one section of the second keel 2b overlaps with the first protrusion 21 of the other section of the second keel 2b, and the slots cc are aligned. A spring (not shown) is inserted into the slots cc to secure the two sections of the second keel 2b.
[0034] The embodiment of the present invention connects the keels by cooperating with the flexible protrusions and the rigid buckle grooves, which can reduce the friction area at the connection, making the keel bracket more flexible and smoother when moving synchronously with the protective sleeve.
[0035] Please continue to see Figure 4In a keel bracket, the second protrusion 22 of one adjacent second keel 2b overlaps with the first protrusion 21 of another adjacent second keel 2b, with the slot cc aligned. A spring (not shown) is inserted into the slot cc for fastening, forming the fastening portion bb of the keel bracket 2. The thickness of this fastening portion bb is the same as that of the keel 2b. In this embodiment of the present invention, the thickness of the fastening portion, formed by the superposition of the first and second protrusions of the keel, is the same as the thickness of the keel, making the connection between adjacent keels more secure and stable.
[0036] Please also refer to Figures 4 to 7 The first keel 2a has grooves 2a3 formed on both its upper and lower end surfaces, and the second keel 2b has two symmetrical hook holes 2b3 formed on its surface. The upper and lower cover crossbars 3 and 4 each have hooks formed on one end, and hooks formed on their opposite ends. The hooks and hooks open in opposite directions. For clarity, the hook formed on one end of the upper cover crossbar 3 is the upper cover hook 31, and the hook formed on the opposite end is the upper cover hook 32. The hook formed on one end of the lower cover crossbar 4 is the lower cover hook 41, and the hook formed on the opposite end is the lower cover hook 42. The upper cover hook 31 is snap-connected with the groove 2a3 on the upper end surface of the first keel 2a, and the lower cover hook 41 is snap-connected with the groove 2a3 on the lower end surface of the first keel 2a; the upper cover hook 32 is hooked and connected with the hook hole 2b3 on the upper surface of the second keel 2b, and the lower cover hook 42 is hooked and connected with the hook hole 2b3 on the lower surface of the second keel 2b.
[0037] The embodiment of the present invention utilizes the cooperation between the buckle hook and the groove, the hook and the hook hole to perform the movable connection between the upper cover cross bar, the lower cover cross bar and the keel, which is not only fastened but also convenient for installation and disassembly.
[0038] Please see Figure 6 and Figure 7 The surface of the lower cover crossbar 4 is provided with at least one mounting hole for mounting a wire separator 5. The wire separator 5 passes through the lower cover 12 of the protective sleeve 1 to separate the pipelines placed in the protective sleeve 1. In this embodiment of the present invention, mounting holes are reserved on the lower cover crossbar to facilitate the movable installation of the wire separator according to the pipeline layout requirements to separate the pipelines in the protective sleeve.
[0039] Please continue to see Figure 1 The pipeline protection device provided in an embodiment of the present invention further includes at least one fixing joint 6 placed at one end of the protective sleeve 1. The fixing joint 6 is arranged on the outside of the keel bracket 2 and is locked and fastened with the keel bracket 2 located on the inside thereof. In the embodiment of the present invention, two parallel rows of screw holes are opened on the side of the fixing joint 6, and correspondingly, screw holes are also opened on the surface of the keel bracket 2. After the screw holes are aligned, the fixing joint 6 and the keel bracket 2 are fixed by screws. In an optional embodiment, the fixing joints 6 are connected to both ends of the protective sleeve 1.
[0040] By adopting the pipeline protection device provided by the present invention, when the protective sleeve moves and bends toward the side of the upper cover, the overhead part is equivalent to the protective sleeve being suspended on the lower cover cross bar, so that the bending degree of the protective sleeve is actually determined by the bending radius of the keel. The bending radius can be smaller, and since there is a gap between the upper cover cross bar and the upper cover, the resistance to the movement of the protective sleeve can be reduced. At the same time, the lower cover cross bar can be used to stabilize the keel, thereby increasing the overhead length.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
