Technical Field

[0001] The utility model relates to the technical field of equipment maintenance, in particular to an auxiliary device for the maintenance of an orifice valve. Background Art

[0002] Orifice valves are conventional equipment in natural gas transmission and distribution stations. Since there are usually impurities in the pipelines in natural gas transmission and distribution stations, it is easy to damage the sealing structure of the orifice plate in the orifice valve and form impurity accumulation. Therefore, the orifice valve needs to be regularly maintained during use. The orifice plate in the orifice valve should be taken out and cleaned, and the sealing structure should be checked and replaced to ensure the normal transmission and distribution of natural gas.

[0003] However, since the orifice plate is a metal plate structure with a certain weight, it is difficult to lift the orifice plate vertically upward from the orifice valve manually, and multiple workers need to cooperate in applying force. In addition, since the orifice valve has a certain height on the pipeline, workers need to stand in a higher position. After maintenance, the orifice plate needs to be placed vertically from top to bottom into the orifice valve. The operation is laborious and there is a risk of equipment and personnel falling. Utility Model Content

[0045] Example 1

[0046] like Figure 1-Figure 4 As shown, this embodiment provides an orifice valve maintenance auxiliary device, including a bracket 1, a lifting mechanism, and a binding belt 5. The bracket 1 realizes the movement function of the orifice valve maintenance auxiliary device through the walking wheels 14 arranged at the bottom, so that the bracket 1 can be moved to the vicinity of the orifice valve; the lifting mechanism is installed on the bracket 1, and is used to assist in lifting and lowering the orifice plate; the binding belt 5 is connected to the lifting mechanism, and is used to bind the orifice plate to realize the connection between the orifice plate and the lifting mechanism.

[0047] In one or several embodiments, the bracket 1 may include a base 11, a vertical support 12 and a cross beam 13, the top ends of the two vertical supports 12 respectively support the ends of the cross beam 13, the bottom ends of the two vertical supports 12 are respectively connected to the base 11, and the bottom of the base 11 is provided with the walking wheels 14.

[0048] In an optional embodiment, the base 11 includes two straight rods arranged in parallel, which can be profile rods such as I-beams, channel steels, aluminum tubes, etc. The straight rods are perpendicular to the crossbeam 13, and the crossbeam 13 can also be made of profile rods such as I-beams, channel steels, aluminum tubes, etc. The vertical support 12 can be an aluminum tube or a steel tube.

[0049] In an optional embodiment, the base 11, the vertical support 12 and the cross beam 13 are all hollow rod-shaped structural members, which can reduce the overall weight of the orifice valve maintenance auxiliary device, facilitate the use of the device, make the maintenance process more labor-saving, and make the preparation of the bracket 1 easier and more convenient to move. At the same time, by using a straight rod of a rod-shaped structural member as the base 11, the overall structure of the bracket 1 is simple and easy to install on an existing pipeline without being affected by the small spacing between adjacent pipelines. Moreover, since the straight rod of the base 11 is perpendicular to the cross beam 13, the bracket 1 occupies a smaller area during movement and is not easily affected by other equipment at the site where the orifice valve is used, which facilitates the overall movement and use of the device.

[0050] In one or several embodiments, the lifting mechanism includes a pulley block 2, a lifting rope 3 and a crank mechanism 4, the pulley block 2 is arranged on the cross beam 13, the crank mechanism 4 is arranged on the vertical support 12, and the crank mechanism 4 is connected to the pulley block 2 through the lifting rope 3.

[0051] In an optional embodiment, the crank mechanism 4 may include a winding mechanism disposed on one side of the vertical support 12 for winding the lifting rope 3 to adjust the length of the lifting rope 3 and further adjust the height of the movable pulley 22.

[0052] In an optional embodiment, the bracket 1 may further include a support rod 6, one end of the support rod 6 is connected to the vertical support 12, and the other end is connected to the base 11, so that the support rod 6, the base 11 and the vertical support 12 are combined to form a triangular stable structure.

[0053] like Figure 2 As shown, in an optional embodiment, two support rods 6 are symmetrically arranged on both sides of the vertical support 12 to strengthen the structure of the vertical support 12, thereby improving the overall structural stability of the bracket 1.

[0054] In an optional embodiment, the pulley block 2 may include a fixed pulley 21, a movable pulley 22 and a steering wheel 23, the fixed pulley 21 and the steering wheel 23 are spaced apart below the cross beam 13, the lifting rope 3 is passed through the fixed pulley 21 and the steering wheel 23, the movable pulley 22 is slidably arranged on the lifting rope 3, and a hook 24 is provided on the movable pulley 22.

[0055] like Figure 1 As shown, in an optional embodiment, the fixed pulley 21 and the steering wheel 23 are arranged in a longitudinally spaced arrangement along the cross beam 13. The fixed pulley 21 is located in the middle of the cross beam 13 and is used to be arranged directly above the orifice valve. The steering wheel 23 is located at one end of the cross beam 13 and is used to steering the lifting rope 3 so that the lifting rope 3 passes through the steering wheel 23 and is connected to the crank mechanism 4.

[0056] like Figure 4As shown, in an optional embodiment, the cross beam 13 is provided with a slide groove 131, and the fixed pulley 21 is slidably set in the slide groove 131. The fixed pulley 21 can be limited in the slide groove 131 by a limiting member, so that the fixed pulley 21 can move along the slide groove 131, changing the position of the fixed pulley 21 relative to the cross beam 13, so that the lifting mechanism can more easily adapt to the position of the orifice plate.

[0057] In an optional implementation manner, the limiting member may be a structural member such as a bolt or a pin on the fixed pulley 21 that can abut against the crossbeam 13 .

[0058] The orifice valve maintenance auxiliary device of the present embodiment is used. When in use, the lifting mechanism is installed through the bracket 1 with the walking wheel 14. When the orifice valve needs maintenance, the bracket 1 is moved to the vicinity of the orifice valve, the bracket 1 is tilted or the bracket 1 is moved in from one end of the line where the pipeline is located, so that the bracket 1 is straddled above the orifice valve, and the lifting mechanism is located directly above the orifice valve. The binding belt 5 passes through the operating hole on the orifice plate, and the two ends are connected to the hook 24 on the movable pulley 22 through the hanging ring, and then the crank mechanism 4 is turned to retract the lifting rope 3 to realize the lifting of the orifice plate, and the orifice plate is manually assisted to be pulled to the vicinity of the pipeline for placement. The placement principle of the orifice plate after maintenance is the same, so that the orifice plate is lifted and placed by the bracket 1 and the lifting mechanism, which makes the orifice valve maintenance process more time-saving and labor-saving, and avoids the risk of personnel falling.

Figure 5As shown, the connection positions of the first support rod 61 and the second support rod 62 on the vertical support 12 are at different heights, so that by reducing the height of the first support rod 61, the vertical support 12 can be moved to a position closer to the pipeline while ensuring the structural stability of the bracket 1, without having to be tilted to straddle the orifice valve, so that the fixed pulley 21 is conveniently set above the orifice to achieve vertical lifting and lowering, further reducing the labor of manual operation.

[0064] In the orifice valve maintenance auxiliary device of the present embodiment, the frame beam 7 can be temporarily installed according to actual conditions, so that the bracket 1 can be adjusted according to the actual use scenario. By arranging the frame beam 7 on the cross beam 13, the lifting mechanism is arranged on one side of the cross beam 13. When in use, the bracket 1 is moved to the vicinity of the pipeline, so that the cross beam 13 is parallel to the longitudinal direction of the pipeline, the lifting mechanism is adjusted to be located above the orifice valve, the lifting mechanism is connected to the orifice plate, and then the orifice plate is lifted and lowered by the crank mechanism 4, so that when the bracket 1 is not straddled on the pipeline, the fixed pulley 21 can be installed above the orifice plate through the lateral extension distance of the frame beam 7, so that the device can be adapted to the on-site use where the adjacent pipeline structure is complex and the bracket 1 cannot be straddled and installed.
