Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pipeline maintenance technology, and specifically relates to a rapid maintenance device for chemical engineering pipelines. Background Technology
[0002] Chemical engineering relies heavily on pipeline networks for material transport. These pipelines operate under harsh conditions such as high temperature, high pressure, corrosion, and vibration, making them highly susceptible to localized leaks due to corrosion, erosion, material defects, or external damage. Traditional welding repair methods require shutdown, depressurization, emptying, and replacement of flammable and toxic media within the pipeline before direct welding repair at the leak point. This method is unsuitable for pipelines carrying flammable and explosive media or for special operating areas where open flames are prohibited. Similarly, the method of mechanically binding leak points with metal clamps operated by operators is also unsuitable for the chemical engineering field. Leaks in chemical engineering pipelines can release toxic, harmful, and highly corrosive gases or liquids, seriously endangering the safety and health of operators.
[0003] A search revealed a prior art patent publication number CN120609000A for a rapid repair composite leak detection device for heat pump pipelines. This device includes two sets of support rings, with guides movably connected to the outer sides of the support rings, and a repair mechanism movably connected to the outer sides of the guides. This device repairs pipe damage by wrapping tape around the pipe. However, the tape cannot withstand the high pressure inside the pipeline, and its chemical stability is insufficient for most chemical solvents and highly corrosive media, making it easily dissolved or corroded. Another prior art patent publication number CN119778570A describes a pipe repair device, comprising a half-type repair device consisting of an upper shell, a lower shell, and a sealing gasket. This device achieves a double-seal effect and anti-slip effect through the sealing gasket. However, this device also requires complete manual operation for leak repair and is unsuitable for leaks of toxic, harmful, or highly corrosive gases or liquids. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a rapid repair device for chemical engineering pipelines. A moving mechanism drives a positioning frame to move along the pipeline. A clamping mechanism on the positioning frame moves a pipe clamp towards the damaged area. A rotating mechanism drives the entire positioning frame to rotate around the pipeline axis. The positioning frame, through a locking mechanism, rotates the pipe clamp, adjusting its orientation to ensure the damaged area is inside the clamp, guaranteeing its leak-proof function. The locking mechanism then tightens the pipe clamp onto the damaged area, ensuring no further liquid leakage after clamping. Once the clamp is installed, the entire device, except for the clamp, is moved back to its starting point via the moving mechanism, and the positioning frame is removed from the pipeline for future use. This avoids direct exposure of operators to toxic, harmful, corrosive, or flammable and explosive leaked media.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A rapid maintenance device for chemical engineering pipelines includes a positioning and moving frame, a moving mechanism, a rotating mechanism, a clamping mechanism, a locking mechanism, and a pipe clamp. The positioning and moving frame and the pipe clamp are both installed on the outer wall of the engineering pipeline. The moving mechanism, rotating mechanism, and clamping mechanism are all installed on the positioning and moving frame. The clamping mechanism simultaneously contacts the pipe clamp, which can drive the pipe clamp to move along the engineering pipeline. The pipe clamp is installed on the locking mechanism, which is also installed on the lower side of the positioning and moving frame.
[0007] The positioning and moving frame includes a positioning ring, a hinge, a pin, and fastening bolts. The positioning ring is an annular clamp that can open and close vertically. A hinge is provided at the connection point on one side of the positioning ring, and a pin is provided inside the hinge. The positioning ring can be opened and closed as a whole through the hinge and the pin. It is then fastened to the anti-loosening washer by the fastening bolts on the other side of the positioning ring to prevent the positioning ring from opening during operation. The positioning ring can be quickly installed at any position on the engineering pipeline through the hinge, pin, and fastening bolts, realizing rapid adjustment and positioning. At the same time, it can be quickly disassembled from the engineering pipeline and can be reused.
[0008] The moving mechanism includes a limiting shaft I, a wheel frame I, a pulley I, a motor I, and a spring I. The moving mechanism as a whole has three sets of equidistant circles arranged on the positioning and moving frame. One end of the limiting shaft I has a limiting ring, and the limiting shaft I passes through the positioning ring and connects to the wheel frame I. The pulley I is set inside the wheel frame I, and the motor I is set on one side of the wheel frame I. The motor I controls the rotation of the pulley I. The spring I is sleeved on the limiting shaft I and is also set between the wheel frame I and the positioning ring. The spring I presses the wheel frame I, and the wheel frame I drives the pulley I to press against the wall of the engineering pipeline. The motor I controls the rotation of the pulley I, driving the entire device to move along the direction of the engineering pipeline.
[0009] The rotating mechanism includes a limiting shaft II, a wheel frame II, pulleys II, a motor II, and a spring II. The rotating mechanism as a whole has three sets of equidistant circular arrangements on the positioning and moving frame. One end of the limiting shaft II has a limiting ring, and the limiting shaft II passes through the positioning ring to connect to the wheel frame II. Multiple sets of pulleys II are arranged inside the wheel frame II. The motor II is arranged on one side of the wheel frame II and controls the rotation of multiple sets of pulleys II. The spring II is sleeved on the limiting shaft II and is also arranged between the wheel frame II and the positioning ring. The spring II presses the wheel frame II, and the wheel frame II drives the multiple sets of pulleys II to press against the wall of the engineering pipeline. The motor II controls the rotation of the pulleys II, driving the entire device to rotate around the engineering pipeline as the axis.
[0010] The clamping mechanism includes a positioning plate I, a limiting shaft III, a positioning plate II, and a spring III. Two sets of clamping mechanisms are provided, symmetrically distributed on the positioning and moving frame. The positioning plate I is fixed inside the positioning ring. One end of the limiting shaft III has a limiting ring. The limiting shaft III passes through the positioning plate I and connects to the positioning plate II. The limiting shaft III and the positioning plate I are slidably connected. The spring III is sleeved on the limiting shaft III and is simultaneously positioned between the positioning plate II and the positioning plate I. The clamping mechanisms at both ends of the positioning and moving frame push out the positioning plate II via the spring III, and the positioning plate II touches the central clamp.
[0011] The locking mechanism includes an electric push rod I, a fixed plate, a connecting shaft I, a movable plate I, a clamping plate, a connecting rod I, a connecting rod II, an electric screwdriver, and a hexagonal drill bit. Two sets of fixed plates are fixed to the lower end of the positioning ring. The electric push rod I is mounted on one set of fixed plates. A movable plate I is located at the protruding end of the electric push rod I. Two sets of movable plates I are provided, with clamping plates at both ends. The two sets of movable plates I are connected by connecting rod I and connecting rod II, which are rotatably connected by a pin. A connecting shaft I is also provided between the two sets of fixed plates. A clamping plate is simultaneously mounted on the connecting shaft I and slidably connected to it. A support frame is mounted on the other set of fixed plates. A connecting shaft II is provided between the support frame and the fixed plate. The electric push rod II is mounted on the support frame. A movable plate II is located at the protruding end of the electric push rod II and slidably connected to the connecting shaft II. Three sets of electric screwdrivers are mounted on the movable plate II, and a hexagonal drill bit is located at the output end of each electric screwdriver.
[0012] The pipe clamp includes a locking sleeve, a sleeve, arc-shaped lugs, grooves, limiting shafts IV, hexagonal socket bolts, and leak-proof washers. The sleeve is C-shaped and nested inside the locking sleeve. The two ends of the locking sleeve are turned outward to form arc-shaped lugs with the locking sleeve itself. Multiple grooves are provided on the arc-shaped lugs. Two sets of limiting shafts IV pass through the middle of the upper and lower arc-shaped lugs. Multiple circular through holes are provided on the limiting shafts IV, allowing the hexagonal socket bolts to pass through. Multiple leak-proof washers are provided inside the sleeve. A welding nut is welded to one side of the limiting shaft IV. The pipe clamp is fitted onto the engineering pipeline through the sleeve. The hexagonal socket bolts and welding nuts are tightened to put the pipe clamp in a pre-clamped state. At this time, the pipe clamp is slidably connected to the engineering pipeline. The lower limiting shaft IV is also set in the clamping plate of the locking mechanism. The electric push rod I of the locking mechanism pushes the moving plate I. The moving plates I on both sides are connected by connecting rod I. Linkage II moves to center, and moving plate I drives the clamping plates at both ends to clamp the limiting shaft IV. The limiting shaft IV on both sides is in the predetermined position, ensuring the pre-clamping state of the pipe clamp, which provides a guarantee for the subsequent tightening of the hexagonal bolts. When the entire device reaches the leak point, the electric push rod II of the locking mechanism pushes the moving plate II. The moving plate II drives multiple sets of electric screwdrivers, so that the hexagonal drill bit is close to the hexagonal bolt. The electric screwdriver controls the rotation of the hexagonal drill bit to tighten the hexagonal bolt and the weld nut. When tightening, the limiting shafts IV on both sides are pulled. The limiting shafts IV pull the locking sleeve. The locking sleeve pulls the sleeve. The sleeve clamps the engineering pipeline. The anti-leakage washer further ensures the sealing of the pipe clamp after clamping and prevents liquid leakage. After ensuring that there is no leakage in the pipeline, the electric screwdriver and clamping plate of the locking mechanism are controlled to reset. The entire device except for the pipe clamp returns to the initial position and is disassembled for future use.
[0013] Furthermore, to facilitate remote operation, the positioning mobile frame is equipped with several cameras, which transmit real-time images to facilitate remote work and quickly and effectively complete pipeline maintenance.
[0014] The advantages of this utility model compared with the prior art are as follows:
[0015] During maintenance, operators do not need to be in close contact with the leak point. They can use the clamping mechanism on the remote-controlled positioning and moving frame to move the pipe clamp towards the damaged area of the pipe. The rotating mechanism drives the entire positioning and moving frame to rotate around the engineering pipeline as the axis. The positioning and moving frame drives the pipe clamp to rotate through the locking mechanism, adjusting the pipe clamp's orientation to ensure that the damaged area of the pipeline is located inside the pipe clamp, ensuring the pipe clamp's leak-proof function. Then, the locking mechanism clamps the opening of the pipe clamp from top to bottom, ensuring that no liquid leaks from the damaged area of the engineering pipeline after the pipe clamp is clamped. Finally, the electric screwdriver of the locking mechanism controls the hexagonal drill bit to approach and rotate, locking the internal hexagonal bolts of the pipe clamp. This avoids the operator being directly exposed to toxic, harmful, corrosive, or flammable and explosive leaked media.
[0016] The upper and lower sets of positioning rings inside the mobile positioning frame are rotatably connected by hinge pins, and then the upper and lower sets of positioning rings are fastened together by fastening bolts. This allows the positioning mobile frame to be quickly installed at any position on the engineering pipeline, achieving rapid adjustment and positioning. It is suitable for engineering pipelines with different pipe diameters, and can be quickly disassembled from the engineering pipeline for repeated deployment and use. Attached Figure Description
