Detailed ways

The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

An embodiment of a pipe laying device for oil well repairing operation of the present invention is shown in FIGS. 1 to 7 . The pipe laying device for oil well repairing operation includes a support frame 100 , a hoisting mechanism, a lifting mechanism 200 and a conveying mechanism.

The hoisting mechanism includes a balancing assembly, a first hook 220, a second hook 230 and a lifting plate 240. The lifting plate 240 is arranged horizontally and connected to the support frame 100 through a cable 110. The support frame 100 is provided with a control system, and the control system controls the retraction and extension of the cable 110. The first hook 220 is hinged to the bottom of the lifting plate 240 through a first hinge shaft. The first hook 220 is used to clamp one end of the pipeline, and then when the lifting plate 240 rises, the first hook 220 drives one end of the pipeline to gradually lift up, and then gradually lifts the pipeline to a vertical state. The first hook 220 and the second hook 230 have the same structure, and the two are arranged symmetrically at the bottom of the lifting plate 240 about the center of the lifting plate 240. The arrangement of the first hook 220 and the second hook 230 can grab two pipelines at the same time and drive the two pipelines to move to a preset position, thereby increasing the efficiency of lifting the pipeline. The second hook 230 is hinged to the bottom of the lifting plate 240 through a second hinge axis, and the first hinge axis and the second hinge axis are coaxial and arranged horizontally. The balancing assembly is arranged between the first hook 220 and the second hook 230, and is used to prevent the lifting plate 240 from rotating under the eccentric force of the pipe when the first hook 220 and the second hook 230 respectively clamp a pipe and lift it upward. When the first hook 220 and the second hook 230 respectively drive the pipe to be lifted upward to a vertical state at the same time, the pipe changes from an inclined state to a vertical state, which will drive the corresponding first hook 220 or the second hook 230 to swing on the lifting plate 240, and the two pipes lifted by the first hook 220 and the second hook 230 are symmetrical about the center of the lifting plate 240, so that the first hook 220 and the second hook 230 swing in opposite directions. When the first hook 220 and the second hook 230 swing relative to each other, the balancing assembly will balance the circumferential deflection force generated by the swinging of the first hook 220 and the second hook 230, so that the first hook 220 and the second hook 230 are in a vertical state, thereby increasing the stability during the pipeline lifting process.

The lifting mechanism 200 is used to gradually lift one end of the pipeline. When one end of the pipeline is lifted to a preset height, the first hook 220 or the second hook 230 clamps the end of the pipeline, and then when the first hook 220 and the second hook 230 clamp the pipeline and lift it, the line between the centers of gravity of the two pipelines remains unchanged. Specifically, the vertical projection of the center of gravity of the two pipelines in the initial state and the vertical projection of the center of gravity of the pipelines during the lifting process are both on the same straight line, thereby reducing the circumferential deflection force of the pipeline on the first hook 220 and the second hook 230 during the lifting process, and further increasing the stability of the pipeline during the lifting process. The conveying mechanism is used to place the pipeline on the lifting mechanism 200.

In this embodiment, as shown in FIGS. 1 to 7 , the balancing assembly includes a damper 211, a first rack 212, and a second rack 213. The first hinge shaft is fixedly connected to the first hook 220; the second hinge shaft is fixedly connected to the second hook 230; a first gear 225 is fixedly provided at one end of the first hinge shaft close to the second hook 230, and when the first hook 220 swings with the first hinge shaft as the axis, the first hinge shaft is driven to rotate, thereby driving the first gear 225 to rotate. A second gear 231 is fixedly provided at one end of the second hinge shaft close to the first hook 220, and when the second hook 230 swings with the second hinge shaft as the axis, the second hinge shaft is driven to rotate, thereby driving the second gear 231 to rotate. The first rack 212 is slidably arranged at the bottom of the lifting plate 240, and the sliding direction is perpendicular to the axis direction of the first gear 225. The first rack 212 is meshed with the first gear 225, and when the first gear 225 rotates, the first rack 212 is driven to slide at the bottom of the lifting plate 240. The second rack 213 is arranged parallel to the first rack 212 and can be slidably arranged at the bottom of the lifting plate 240. The second rack 213 is meshed with the second gear 231. When the second gear 231 rotates, the second rack 213 is driven to slide at the bottom of the lifting plate 240. Since the first hook 220 and the second hook 230 are symmetrically arranged about the center of the lifting plate 240, when the first hook 220 and the second hook 230 lift the pipe, the first hinge shaft and the second hinge shaft rotate in opposite directions, and then the first gear 225 and the second gear 231 drive the first rack 212 and the second rack 213 to slide in opposite directions. The damper 211 is arranged between the first rack 212 and the second rack 213, and a damping shaft extends from both ends. The damping shaft of the damper 211 is parallel to the first rack 212. The damping shafts at both ends of the damper 211 are respectively fixedly connected to the first rack 212 and the second rack 213 through the connecting rod. When the first rack 212 and the second rack 213 slide relative to each other, the damping shafts at both ends of the damper 211 are driven to slide in the damper 211. Due to the damping effect in the damper 211, the damper 211 exerts opposite forces on the first rack 212 and the second rack 213 through the damping shaft. When the first hook 220 and the second hook 230 swing with the corresponding first hinge shaft and the second hinge shaft as the axis, a clockwise deflection force is exerted on the lifting plate 240. The damping shaft exerts opposite forces on the first rack 212 and the second rack 213, respectively, and can exert a counterclockwise deflection force on the lifting plate 240, so that the two opposite deflection forces offset each other, thereby offsetting the swing of the first hook 220 and the second hook 230.

In this embodiment, as shown in FIGS. 1 to 7 , the lifting mechanism 200 includes a first lifting platform 320, a second lifting platform 330 and a plurality of adjusting rails 310. The adjusting rails 310 are horizontally arranged on the ground and fixed to the ground. The projections of the adjusting rails 310 and the first hinge axis in the vertical direction are perpendicular to each other. The plurality of adjusting rails 310 are evenly distributed along the axis direction of the first hinge axis. The conveying mechanism is used to place the pipeline on the first lifting platform 320 and the second lifting platform 330 respectively; the first lifting platform 320 and the second lifting platform 330 are both slidably arranged on the adjusting slide rail 310, and the first lifting platform 320 and the second lifting platform 330 are inclined along the extension direction of the adjusting slide rail 310. Specifically, the vertical projections of the pipeline on the first lifting platform 320 and the second lifting platform 330 are not perpendicular to the adjusting slide rail 310, so that the pipeline is inclined, and the vertical projections of the center of gravity of the two pipelines are always on the same straight line, thereby weakening the circumferential deflection force on the lifting plate 240 caused by the swing when the pipeline is lifted. The first lifting platform 320 and the second lifting platform 330 are symmetrical about the center of the lifting plate 240. The first lifting platform 320 and the second lifting platform 330 are used to lift one end of the pipeline. When the first hook 220 and the second hook 230 clamp the pipeline and lift it up, the first lifting platform 320 and the second lifting platform 330 slide along the adjusting slide rail 310, so that the projections of the centers of gravity of the two pipelines in the vertical direction are on the same straight line, so that after the pipeline is completely separated from the first lifting platform 320 or the second lifting platform 330, the first hook 220 and the second hook 230 are subjected to a greater swinging tendency. The first hook 220 and the second hook 230 are subjected to a greater swinging tendency, so that the first rack 212 and the second rack 213 slide faster, thereby causing the damper 211 to generate greater damping, so as to reduce the circumferential deflection force of the pipeline on the first hook 220 and the second hook 230 during the lifting process.

In this embodiment, as shown in FIGS. 1 to 6 , the first lifting platform 320 and the second lifting platform 330 have the same structure. The first lifting platform 320 includes a sliding plate 321, a lifting catwalk 322 and a push plate 323. The sliding plate 321 can be slidably arranged on the adjustment rail 310. The lifting catwalk 322 is horizontally arranged on the sliding plate 321, and one end is hinged to the sliding plate 321. When the angle between the lifting catwalk 322 and the sliding plate 321 increases, the other end of the lifting catwalk 322 is lifted upward, thereby converting the pipeline from a horizontal state to an inclined state. Specifically, the vertical projection of the lifting catwalk 322 is not perpendicular to the adjustment rail 310. A hydraulic component is arranged between the lifting catwalk 322 and the sliding plate 321, and the hydraulic component can lift the other end of the lifting catwalk 322 upward; the hydraulic component is specifically a hydraulic lifter. The push plate 323 can be slidably arranged on the lifting catwalk 322. The push plate 323 can contact the end of the pipeline. When the first hook 220 lifts the pipeline, the push plate 323 pushes the pipeline to slide toward one side of the first hook 220. The push plate 323 can provide thrust for the pipeline during the lifting process. When the push plate 323 slides along the lifting catwalk 322, the sliding plate 321 slides along the adjustment slide rail 310. The sliding direction of the sliding plate 321 of the first lifting platform 320 is opposite to the sliding direction of the sliding plate 321 of the second lifting platform 330. When the push plate 323 slides, it indicates that the pipeline is in the lifting stage. At this time, the sliding of the sliding plate 321 can adjust the center of gravity of the pipeline. In particular, the lifting catwalk 322 is provided with a first power mechanism, and the first power mechanism drives the push plate 323 to slide along the lifting catwalk 322; the adjustment slide rail 310 is provided with a second power mechanism, and the second power mechanism drives the sliding plate 321 to slide along the sliding track.

In this embodiment, as shown in Figures 1 to 7, the conveying mechanism includes a placement platform 420, a conveying slide 410, a conveying frame 440 and an electromagnetic lifting unit 430. The placement platform 420 is set on the ground, and multiple pipes are placed on the placement platform 420. The conveying slide 410 is parallel to the adjustment slide 310 and fixed to the ground. The number of conveying slides 410 is two, and multiple adjustment slides 310 are set between the two conveying slides 410. The conveying frame 440 can be slidably set on the conveying slide 410, and the two ends of the conveying frame 440 are respectively slidably set on a conveying slide 410, and the conveying frame 440 is provided with a track perpendicular to the conveying slide 410. The electromagnetic lifting unit 430 can be slidably set on the conveying frame 440 to transfer the pipeline to the lifting catwalk 322 of the first lifting platform 320 or the second lifting platform 330. Specifically, the electromagnetic lifting unit 430 includes a sliding block 431 and an electromagnet 432. The sliding block 431 can be slidably arranged on the conveying frame 440. The electromagnet 432 can be rotatably and slidably arranged below the sliding block 431, and is used to adsorb or release the pipeline. The rotation of the electromagnet 432 can place the pipeline on the corresponding first lifting catwalk 322 or the second lifting catwalk 322.

In this embodiment, as shown in Figures 3 to 7, the first hook 220 includes a connecting plate 221, a connecting block 222 and a clamping portion. The connecting plate 221 is tilted, and the lateral edge of the upper end is hinged to the lifting plate 240 through a first hinge shaft, and the connecting plate 221 and the first hinge shaft are fixedly connected. When the connecting plate 221 swings, the first hinge shaft is driven to rotate, and then the first gear 225 is driven to rotate. Due to the tilted setting of the connecting plate 221, when the connecting plate 221 is subjected to a downward pulling force, the pulling force on the connecting plate 221 causes the connecting plate 221 to change from an inclined state to a vertical state, and then the connecting plate 221 drives the first hinge shaft to rotate. The connecting block 222 is connected to the lateral edge of the lower end of the connecting plate 221. The clamping portion is arranged on the connecting block 222, and is used to manually fix and clamp one end of the pipeline. The connecting plate 221 of the second hook 230 is tilted in the opposite direction to the connecting plate 221 of the first hook 220, and the connecting plate 221 of the second hook 230 is fixedly connected to the second hinge shaft. The clamping portion includes a lifting ring 223 and a clamp 224. The clamp 224 can be fixedly sleeved with one end of the pipe manually; one end of the lifting ring 223 is connected to the connecting block 222, and the other end is connected to the clamp 224. Specifically, there are two lifting rings 223, two lifting rings 223 are connected to one clamp 224, and the clamp 224 can swing on the connecting block 222 through the two lifting rings 223, and the extension line of the vertical projection of the axis of the swing of the clamp 224 on the connecting block 222 intersects with the extension line of the vertical projection of the first hinge shaft.

In this embodiment, as shown in FIG. 3 to FIG. 5 , two hinged seats 241 are symmetrically provided at the bottom of the lifting plate 240 ; the first hook 220 is hinged to one hinged seat 241 through a first hinge axis, and the second hook 230 is hinged to one hinged seat 241 through a second hinge axis.

During operation, as shown in FIGS. 1 to 7 , the required pipe is first placed on the placement platform 420. The electromagnet 432 is activated to lift the pipe by suction. The conveying frame 440 slides on the conveying slide rail 410 and the sliding block 431 slides on the conveying frame 440, and the electromagnet 432 transfers the pipe to the lifting catwalk 322 of the first lifting platform 320. After the same steps as above, another pipe is transferred to the lifting catwalk 322 of the second lifting platform 330.

When pipelines are placed on the lifting catwalks 322 of the first lifting platform 320 and the second lifting platform 330, the hydraulic components on the first lifting platform 320 and the second lifting platform 330 are started simultaneously. The other end of the lifting catwalk 322 is gradually lifted upward, so that the pipeline gradually changes from a horizontal state to an inclined state. When the lifting catwalk 322 drives the inclined angle of the pipeline to reach a preset angle value, the clamping members 224 on the first hook 220 and the second hook 230 are manually clamped and connected to the higher end of the corresponding pipeline.

After the clamping members 224 on the first hook 220 and the second hook 230 are connected to the ends of the corresponding pipes, the support frame 100 lifts the lifting plate 240 through the cable 110. At the same time, the push plate 323 exerts a thrust on the pipe along the lifting catwalk 322. When the push plate 323 slides, the sliding plate 321 slides along the adjustment rail 310, and the sliding direction of the sliding plate 321 of the first lifting platform 320 is opposite to that of the sliding plate 321 of the second lifting platform 330. The relative sliding of the two sliding plates 321 can adjust the center of gravity of the pipe during the lifting process, so that the projection of the center of gravity of the pipe in the vertical direction during the lifting process is on the same straight line. After the two pipes are completely lifted by the first hook 220 and the second hook 230 and separated from the corresponding lifting catwalk 322, the pipes are affected by gravity, which causes the pipes to quickly change from tilted to vertical, so the pipes are subject to a greater swinging tendency, and at the same time drive the connecting plate 221 to have a tendency to change from an inclined state to a vertical state, and the connecting plate 221 is subjected to a greater torsional force. The first hinge shaft and the second hinge shaft drive the first rack 212 and the second rack 213 to slide through the first gear 225 and the second gear 231 respectively. At this time, the swing direction of the first hook 220 driven by the pipe is opposite to the swing direction of the second hook 230, so that the sliding directions of the first rack 212 and the second rack 213 are opposite. When the first rack 212 and the second rack 213 slide relative to each other, the damping shafts at both ends of the damper 211 are driven to slide in the damper 211. Since there is a damping effect in the damper 211, the damper 211 exerts opposite forces on the first rack 212 and the second rack 213 through the damping shaft. When the first hook 220 and the second hook 230 swing with the corresponding first hinge shaft and the second hinge shaft as the axis, there is a clockwise deflection force on the lifting plate 240. At the same time, the damping shaft exerts opposite forces on the first rack 212 and the second rack 213 respectively, which can apply a counterclockwise deflection force to the lifting plate 240, so that the two opposite deflection forces cancel each other out, thereby offsetting the swing of the first hook 220 and the second hook 230, thereby keeping the pipeline in a stable lifting state, further increasing construction efficiency.

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, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
