Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of supporting devices and relates to an early warning type supporting device. Background Art
[0002] As gas field development enters the middle and late stages, the aging problem of its production facilities has become increasingly prominent, especially the intricate pipeline network and precision valve system between the gas wellhead and the gas gathering station. The stability of its supporting structure has become a major challenge to ensure safe production. Although the loosening of these supporting structures may seem minor, it is like "an ant hole bursting a dam". It occurs frequently and is difficult to cure. It is widely distributed in every corner of production, which not only increases the complexity and difficulty of equipment maintenance, but also poses a potential threat to the efficient and stable supply of natural gas.
[0003] In-depth analysis shows that the main reasons for the loosening of valve supports can be attributed to three points: first, the aging and wear of the rubber material in the support pipe bracket caused by long-term use, which leads to slippage and weakens the support force; second, the limit nut is loose due to environmental corrosion or improper operation, and cannot effectively lock the position of the pipeline or valve; third, the sinking of the base caused by geological factors such as foundation settlement directly affects the stability of the support structure. These problems are intertwined, forming a complex network of safety hazards, which requires production units to spend a lot of manpower on daily inspections and immediate repairs. Utility Model Content
[0004] The utility model aims to solve the technical problem of looseness of valve supporting devices in the prior art and to provide an early warning supporting device.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] In the first aspect, the utility model provides an early warning support device, including a support base, a support sleeve fixedly connected to the support base, the support sleeve movably connected to a support lifting screw, a spring fastening nut is arranged on the support lifting screw, the upper end surface of the spring fastening nut supports a strong spring sleeved on the support lifting screw, and the top end of the strong spring is fixedly connected to a pipe support; in the initial installation state, when the strong spring is compressed to the limit state, the pipe support fits tightly with the supported structure.
[0007] Further improvements are:
[0008] The upper end surface of the spring fastening nut is fixedly connected with a lower guide rail sleeve, and the inner diameter of the lower guide rail sleeve is loosely matched with the outer diameter of the powerful spring; the bottom of the pipe support is provided with an upper guide rail sleeve opposite to the lower guide rail sleeve; the sum of the lengths of the upper guide rail sleeve and the lower guide rail sleeve is less than the length of the powerful spring when it is compressed to the limit state.
[0009] The strong spring is provided with a strong spring loosening warning section; when the strong spring is compressed to the limit state, the strong spring loosening warning section is located at the part of the strong spring blocked by the upper guide rail sleeve or the lower guide rail sleeve, and when the strong spring starts to loosen, the strong spring loosening warning section is gradually exposed.
[0010] The lower guide rail sleeve and the spring fastening nut are fixedly connected by spot welding.
[0011] The pipe support and the upper guide rail sleeve are an integrated structure.
[0012] A vertical lifting screw fixing groove is arranged at the top end of the supporting lifting screw, and a pipe support fixing key is arranged at a position corresponding to the key groove on the inner wall of the upper guide rail sleeve.
[0013] The support lifting screw rod and the support sleeve are threadedly connected; a support screw rod fixing nut is arranged at the connection between the support lifting screw rod and the support sleeve.

[0016] Supporting plate reinforcement is arranged between the supporting base and the supporting sleeve.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] The utility model discloses an early warning support device, in which a support lifting screw is movably connected in a support sleeve on a support base, so that the height of the whole device can be adjusted, and supported structures of different heights can be used. In addition, a strong spring is sleeved on the support screw, and the lower end of the strong spring is supported by a spring fastening nut arranged on the support lifting screw, and the upper end of the strong spring is fixedly connected to the support sleeve. When the strong spring is compressed to the limit state, the pipe support and the supported structure fit tightly to achieve a stable support effect. When the support device becomes loose, a distance is generated between the pipe support and the supported structure. At this time, the strong spring provides an upward reaction force, so that the pipe support and the supported structure fit tightly again. In addition, the lower end of the strong spring is supported by a spring fastening nut arranged on the support lifting screw, and the position of the spring fastening nut on the support lifting screw is adjustable, and a matching strong spring can be replaced according to specific circumstances.
[0019] Furthermore, a lower guide rail sleeve is fixedly connected to the upper end face of the spring fastening nut, and an upper guide rail sleeve is fixedly connected to the bottom of the pipe support. The inner diameters of the lower guide rail sleeve and the upper guide rail sleeve are clearance-matched with the outer diameter of the strong spring to prevent the strong spring from being eccentric; and, the sum of the lengths of the upper guide rail sleeve and the lower guide rail sleeve is less than the length of the strong spring when it is compressed to the limit state.

[0020] Furthermore, the lower guide rail sleeve and the spring fastening nut are fixedly connected by spot welding, and a gap is left between the lower guide rail sleeve and the spring fastening nut, so that rainwater and other debris flowing into the lower guide rail sleeve can flow out through the gap.
[0021] Furthermore, the support lifting screw and the support sleeve are threadedly connected, and a support screw fixing nut and a support fastening nut are provided at the connection between the support lifting screw and the support sleeve, and a spring washer is provided between the support fastening nut and the support screw fixing nut to reduce the frequency of support loosening.
