[0036] Compared with the prior art, the utility model provides a natural gas pipeline 3 support device. The base 5 is fixed on the ground, and then the first curved plate 1 supports the pipeline 3. After the angle between the first curved plate 1 and the hinge seat 6 is determined, the position of the rotating shaft 12 is fixed by the limiting structure 7, and the limiting structure 7 is connected to the second curved plate 2. Therefore, while limiting the rotation of the first curved plate 1, the second curved plate 2 can clamp the gas pipeline. Through the above-mentioned configuration of the present application, it is convenient to provide support for the inclined pipeline.

[0037] In some embodiments, Figures 1 to 8As shown, one end of the rotating shaft 12 passes through the hinge seat 6, and the limiting structure 7 includes a gear 71 and a stopping tooth 72; the gear 71 is connected to the passing end of the rotating shaft 12; the stopping tooth 72 is inserted between adjacent teeth of the gear 71; a pin shaft 73 is connected to the stopping tooth 72, and the hinge seat 6 has a through hole for the pin shaft 73 to pass through; wherein, one end of the pin shaft 73 is connected to one end of the second arc plate 2, and the other end of the pin shaft 73 is snap-fitted with the other end of the second arc plate 2.

[0038] It should be noted that the hinge seat 6 has a positioning groove 62 for the stop tooth 72 to be plugged in and matched, and the gear 71 is fixed on the rotating shaft 12. When the first curved plate 1 rotates, the gear 71 can rotate with the rotating shaft 12; after the first curved plate 1 is rotated into place, the stop tooth 72 is plugged in and matched with the gear 71, and the stop tooth 72 is plugged in and matched with the positioning groove 62. At this time, the rotation of the gear 71 can be limited, thereby facilitating the first curved plate 1 to support the inclined conveying pipe 3.

[0039] In addition, by arranging a pin shaft 73 on the stop tooth 72 and passing the pin shaft 73 through the hinge seat 6 , the other end of the pin shaft 73 can be engaged with the other end of the second arc plate 2 so that the second arc plate 2 clamps the conveying pipe 3 .

[0040] In some embodiments, Figures 1 to 8 As shown, the pin shaft 73 includes a stop section and a clamping section, and the stop tooth 72 is connected to the stop section; the clamping section passes through the hinge seat 6, and a conical elastic member 74 is provided on the outer peripheral wall of the clamping section, and the large end of the conical elastic member 74 faces the stop section; the other end of the second arc plate 2 has a clamping hole 21, and the diameter of the clamping hole 21 is smaller than the large end diameter of the conical elastic member 74. When the clamping hole 21 is clamped with the conical elastic member 74, the conical elastic member 74 axially limits the other end of the second arc plate 2. The end of the stop section has a threaded hole, and the end of the clamping section is connected to a screw 75, and the clamping section and the stop section are threadedly matched.

[0041] It should be noted that before fixing the first arc plate 1, the clamping section and the anti-rotation section are separately provided; first adjust the angle of the first arc plate 1, and then pass the clamping section through the hinge seat 6, at which time the stop tooth 72 is plugged into and matched with the positioning groove 62 on the hinge seat 6, and the stop tooth 72 is plugged between two adjacent teeth of the gear 71, so that the rotation of the rotating shaft 12 can be limited. The clamping section is connected to the thread of the anti-rotation section through the screw 75, and the clamping section can be fixed on the anti-rotation section, and one of the conical elastic members 74 on the clamping section contacts the hinge seat 6 to axially limit the anti-rotation section, thereby reducing the separation of the stop tooth 72 and the positioning groove 62.

[0042] In addition, after the clamping section is connected to the rotation-stopping section, the clamping hole 21 at the other end of the second arc plate 2 is inserted into the clamping section, and the clamping hole 21 is moved to a preset position, so that the second arc plate 2 clamps the delivery pipe 3. During the process of the clamping hole 21 sliding along the axial direction of the clamping section, each conical elastic member 74 will be deformed, and after the clamping hole 21 passes through the conical elastic member 74, the conical elastic member 74 will be reset.

[0043] In some embodiments, Figures 1 to 8 As shown, the limiting structure 7 also includes a push sleeve 76, which is sleeved on the clamping section of the pin shaft 73, and is used to push the other end of the second arc plate 2 so that the other end of the second arc plate 2 is clamped in place. At least two push plates 77 are connected to the outer peripheral wall of the push sleeve 76, and the push plates 77 are distributed at intervals along the circumference of the push sleeve 76. The diameter of the push sleeve 76 is larger than the diameter of the large end of the conical elastic member 74.

[0044] It should be noted that, in the process of sleeve-mounting the other end of the second arc-shaped plate 2 on the clamping section, the push sleeve 76 can be sleeved on the clamping section, and the other end of the second arc-shaped plate 2 can be pushed into place by pushing the push sleeve 76. By providing a push plate 77 on the outer peripheral wall of the push sleeve 76, it is convenient for the operator to apply a push force to the push sleeve 76 along the axial direction, thereby facilitating the push of the other end of the second arc-shaped plate 2 into place.

[0045] In some embodiments, Figures 1 to 8 As shown, the connection position between the base 5 and the support 4 has a plurality of ribs 51, and the ribs 51 are fixed on the base 5 and the support 4. The base 5 has reserved holes for the anchor bolts to pass through; the base 5 is fixed to the ground by the anchor bolts.

[0046] It should be noted that by setting a rib 51 between the base 5 and the support part 4, the connection strength between the base 5 and the support part 4 can be strengthened; by setting a reserved hole on the base 5, it is convenient for the anchor bolts to pass through the reserved holes of the base 5, and then the base 5 can be fixed to the ground by the cooperation of the nut and the anchor bolt.

[0047] In some embodiments, Figures 1 to 8 As shown, the support part 4 includes a telescopic sleeve 41 and a telescopic rod 42, and the telescopic rod 42 is slidably arranged in the telescopic sleeve 41; the telescopic rod 42 has a plurality of first positioning holes 421 along its height direction, and the telescopic sleeve 41 has a second positioning hole aligned with the first positioning hole 421; the telescopic sleeve 41 has a positioning shaft 43 for plugging and matching with the first positioning hole 421 and the second positioning hole. The second positioning hole is a threaded hole, and the positioning shaft 43 has an external thread, and the positioning shaft 43 is threadedly matched with the second positioning hole.

[0048] It should be noted that the articulated seat 6 is connected to the telescopic rod 42, and the telescopic sleeve 41 is fixed on the base 5; when the overall height needs to be adjusted, the telescopic rod 42 is slid upward to increase the overall height. After adjusting to the preset height, the second positioning hole on the telescopic sleeve 41 is aligned with the first positioning hole 421 on the telescopic rod 42, and then the positioning shaft 43 is plugged into and matched with the first positioning hole 421 and the second positioning hole to fix the telescopic rod 42 in the telescopic position.

[0049] In addition, the positioning shaft 43 is connected to the second positioning hole through a threaded connection, which can improve the connection between the positioning shaft 43 and the second positioning hole and reduce the situation where the positioning shaft 43 is separated from the second positioning hole.

[0050] 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 protection scope of the present invention.
