[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", "inner", "outer", "front", "back", "horizontal", and "vertical" are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0021] It should be noted that the terms "horizontal" and "vertical" in this utility model are used to describe approximate positional relationships, and not strictly "horizontal plane" or "vertical plane". Example

[0022] Please refer to Figures 1 to 4 As shown, this embodiment provides an oil and gas pipeline locking device, including a vehicle body 10, the top surface of which is provided with an installation plane; secondly, it includes a lifting mechanism, which is disposed on the installation plane, and the lifting mechanism is provided with a lifting platform 20, which is located directly above the lifting mechanism; thirdly, it includes a support seat 30, which is disposed on the top surface of the lifting platform 20, and the top of the support seat 30 is excavated with a support groove 31, which is cylindrical, and the two ends of the support groove 31 respectively pass through the support seat 30, and the support groove 31 is used to place the pipeline to be fixed; fourthly, it includes a plurality of locking half clamps 40, which are detachably connected to the support seat 30 so that the pipeline to be fixed is clamped and fixed between the locking half clamps 40 and the bottom of the support groove 31.

[0023] The oil and gas pipeline locking device disclosed in this embodiment uses a vehicle body 10 and a support seat 30. A support groove 31 is dug on the top of the support seat 30 to support the oil and gas pipeline. The vehicle body 10 carries both the oil and gas pipeline together for transport between different pipeline docking points. A lifting mechanism is provided, including a lifting platform 20. The support seat 30 is located on top of the lifting platform 20. The lifting mechanism drives the lifting platform 20 to rise and fall, thereby driving the support seat 30 to rise and fall, and thus driving the natural gas pipeline to rise and fall, so as to adaptively adjust the docking height and solve the problem of docking height deviation. The support groove 31 is cylindrical. The groove allows the natural gas pipeline to roll within the bearing groove 31 under external force, thereby adjusting the circumferential angle of the natural gas pipeline. By setting multiple locking half-hoops 40, which are detachably connected to the bearing seat 30, the pipeline is locked with the locking half-hoops 40 after the height and circumferential angle are adjusted, thus stably fixing it within the bearing groove 31 and preventing unnecessary movement during the docking installation process. Through the cooperation of the above features, the oil and gas pipeline locking device can effectively solve the problems of inconvenient transportation, inability to effectively adjust height and circumferential angle deviations, and inability to effectively lock the pipeline after adjustment during the docking installation of aboveground oil and gas pipelines.

[0024] To further reduce the friction between the pipe and the bearing groove 31 and make the pipe easier to roll and adjust, the bottom of the bearing groove 31 is provided with a number of auxiliary rollers 311 or auxiliary balls; the axial direction of the auxiliary rollers 311 is parallel to the axial direction of the bearing groove 31, and the roller surface of the auxiliary rollers 311 is used to roll and cooperate with the side wall of the pipe to be fixed.

[0025] To provide a specific explanation of the connection structure between the bearing seat 30 and the locking half-hoop 40, the bearing seat 30 is a horizontally arranged semi-cylindrical shape, forming the bearing groove 31 inside; the two sides of the bearing seat 30 extend outward in the horizontal direction to form a pair of first connecting edges 32, and the first connecting edges 32 have multiple first connecting holes 321 vertically through them; the locking half-hoop 40 is arc-shaped, and the two ends of the locking half-hoop 40 are respectively provided with a pair of second connecting edges 41, and the second connecting edges 41 have multiple second connecting holes 411 vertically through them; the first connecting edges 32 and the corresponding second connecting edges 41 are fixedly connected by bolts and nuts, and the bolts pass through the corresponding first connecting holes 321 and the corresponding second connecting holes 411 in sequence before being screwed onto the nuts.

[0026] With the above settings, when the height and circumferential angle have not been adjusted, simple fixation can be achieved by not tightening the bolts and nuts. After the adjustment is completed, tighten the bolts and nuts to lock and fix the device.

[0027] To further adjust the horizontal orientation of the pipeline, a turntable 50 is horizontally rotatably connected to the mounting plane, and the lifting mechanism is located on the top surface of the turntable 50.

[0028] To further explain the specific structure of the lifting mechanism, the lifting mechanism includes a base plate 21, an active arm 22, a driven arm 23, and a lifting platform 20; the base plate 21 is horizontally disposed on the top surface of the turntable 50 and is fixedly connected to the turntable 50; one end of the active arm 22 is hinged to the bottom of the lifting platform 20, and the other end is hinged to a hydraulic cylinder 24, which is fixedly disposed on the base plate 21; one end of the driven arm 23 is hinged to the top surface of the base plate 21, and the other end is rotatably connected to a rotating shaft, which is slidably connected to the lifting platform 20 in the horizontal direction; the middle part of the driven arm 23 is hinged to the middle part of the active arm 22.

[0029] To limit the descent of the lifting mechanism and prevent the weight of the pipeline from crushing it, the base plate 21 has multiple lower limit blocks 211 protruding upwards, and the bottom of the lifting platform 20 has multiple upper limit blocks 201 protruding downwards. The upper limit blocks 201 correspond one-to-one with the lower limit blocks 211 and are aligned vertically. When the upper limit block 201 abuts against the corresponding lower limit block 211, the lifting mechanism descends to its lowest position.

[0030] To prevent unnecessary movement of the vehicle body 10 during docking, the vehicle body 10 is provided with multiple support legs 11 on its periphery. Each support leg 11 is vertically provided with a hydraulic telescopic rod 111, and the bottom end of the hydraulic telescopic rod 111 is horizontally provided with a support plate 112.

[0031] With the above setup, after the pipeline is transported to the docking point, the direction of the pipeline is adjusted by slightly moving the vehicle body 10. Then, the hydraulic telescopic rod 111 drives the support plate 112 to approach and contact the ground until it is strongly pressed against the ground, thus achieving the braking effect.

[0032] To further improve the support stability of the vehicle body 10 during braking, the support leg 11 is strip-shaped, and one end of the support leg 11 is hinged to the side wall of the vehicle body 10 so that the support leg 11 can rotate in the horizontal plane. The hydraulic telescopic rod 111 is provided at the free end of the support leg 11.

[0033] To prevent the support legs 11 from scraping against the external environment during the movement of the vehicle body 10, the vehicle body 10 is provided with two pairs of support legs 11. The two pairs of support legs 11 are symmetrically arranged on both sides of the width direction of the vehicle body 10 and are located at both ends of the length direction of the vehicle body. The support legs 11 can be rotated to fit against the side wall of the vehicle body 10 in the width direction.

[0034] In order to provide structural support for the support leg 11 in the storage state and avoid the impact of the hinge shaft due to prolonged suspension, a support platform 12 is provided in the middle of the width direction of the vehicle body 10. When the support leg 11 is rotated to fit against the side wall of the width direction of the vehicle body 10, the support plate 112 can be placed on the support platform 12.

[0035] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
