Description

Technical Field

[0001] The present invention relates to the technical field of oil pipeline equipment, and more specifically, to a multi-stage adjustable pipe support bracket installed based on oil pipelines. Background Art

[0002] In the process of oil transportation, pipelines for transporting oil are usually laid on the ground, so it is necessary to set up brackets on the pipelines to support the pipelines. Pipeline brackets are also called pipeline supports, pipe sections, etc. According to the operating performance and layout requirements of the pipelines, pipeline brackets are divided into fixed and movable types. In the process of oil transportation, a large number of oil pipelines are needed. These oil pipelines are either buried under the ground or erected at a certain height from the ground.

[0003] Utility model patent CN205534605U discloses a petroleum pipeline support, which uses a nut screw mechanism to press the pipeline onto the fixed part, avoiding the gap between the cover plate and the pipeline due to the error of the outer diameter of the pipeline, and solving the problem of pipeline loosening;

[0004] However, the above-mentioned patent document only has the function of stably fixing the two sections of the pipeline. In actual application, since the prior art does not have a configuration that can keep the two sections of the pipeline in a relatively parallel and corresponding state, that is, the two sections of the pipeline cannot be directly and synchronously located at the same horizontal height and corresponding position during installation through the traditional bracket, and the two sections of the pipeline need to be adjusted and corresponded, which affects the efficiency of the oil pipeline installation and cannot improve the convenience of installation. At the same time, there is also a lack of a pushing auxiliary structure for the pipeline during the installation of the oil pipeline. When the two sections of the pipeline are installed in correspondence, they need to be dragged and pulled to make the interface position fit together for installation.

[0005] In view of the above technical defects, a solution is now provided. Summary of the invention

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-stage adjustable pipe support bracket based on the installation of oil pipelines. The bracket cooperates with the setting of an assumption mechanism and a limiting clamping mechanism. When the oil pipeline is installed, one section of the pipeline is first stabilized, and then the other section of the pipeline is placed on a movable lifting frame, so that the lifting frame is synchronously adjusted according to the height of the limiting frame, and its position is limited by the clamping plates on both sides of the interface to ensure that the two sections of the pipeline can fit completely and correspond to each other, thereby improving the efficiency of installation. At the same time, a clamping and pushing mechanism is provided to assist, and clamping and pushing plates are provided on both sides of the pipeline on the movable side, that is, the pipeline is pushed and driven, so that the pipeline can be pushed close to another pipeline, and at the same time, the clamping plates on both sides of the interface are evacuated, so that the two interfaces can fit tightly, which is convenient for installing the fixed structure of the interface, so as to solve the problems raised in the above-mentioned background technology.

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.

[0038] like Figure 5 As shown, a second pushing rod 57 is fixedly installed on one side of the multiple first pushing rods 54, and the multiple second pushing rods 57 are slidably installed on the inner wall of the clamping plate 53. A second roller rod 58 is rotatably installed on one side of the multiple second pushing rods 57. The multiple second roller rods 58 are in contact with the outer wall of the second pipe 2, and then the positions of the multiple first pushing rods 54 are corresponding to the outer wall of the first pipe 1, that is, the second pushing rods 57 driven by the multiple first pushing rods 54 make the second roller rod 58 maintain a corresponding state, so that when the second pipe 2 extends into the range between the multiple second roller rods 58, it is simultaneously squeezed and guided to keep corresponding to the position of the first pipe 1, ensuring that the interfaces of the two sections of the pipe can be fully fitted and corresponding, thereby improving the efficiency of installation.

[0040] The limit blocks 49 driven by the push plates 48 on both sides of the limit frame 43 are kept horizontal, and then when the lifting frame 45 lifts the second pipe 2 close to the first pipe 1, the collars 410 on both sides of the lifting frame 45 contact and penetrate the limit blocks 49, so that the limit blocks 49 squeeze the collars 410 through their triangular slopes, so that the limit blocks 49 squeeze the collars 410 to keep them horizontal with the limit blocks 49, and the height of the lifting frame 45 is finally consistent with the height of the limit frame 43, that is, the height of the second pipe 2 is consistent with the height of the first pipe 1;

[0041] At the same time, the clamping plate 53 driven by the fixed bracket 51 is located on both sides of the first pipe 1, that is, the multiple first pushing rods 54 in the clamping plate 53 drive the first roller rod 56 to squeeze the outer wall of the first pipe 1 under the squeezing of the clamping spring 55, and then the positions of the multiple first pushing rods 54 are corresponding to the outer wall of the first pipe 1, that is, the second pushing rods 57 driven by the multiple first pushing rods 54 make the second roller rod 58 maintain a corresponding state, so that when the second pipe 2 extends into the range between the multiple second roller rods 58, it is simultaneously squeezed and guided to keep corresponding to the position of the first pipe 1, ensuring that the interfaces of the two sections of the pipe can fit completely and correspond, thereby improving the efficiency of installation.

Two push rods 63 are fixedly installed on one side of the connecting plate 61. The two push rods 63 are arranged in a horizontal state, and one side of the two push rods 63 is in contact with the outer wall of the fixed bracket 51. The push-pull handle 62 can push the connecting plate 61 to drive the two push rods 63 to squeeze and push the fixed bracket 51, and then compress the limit spring through the fixed bracket 51 and drive the clamps on both sides to move synchronously.

[0043] like Figure 7 As shown, the two sides of the top of the joint plate 61 are fixedly installed with limited push plates 64, and the two limited push plates 64 are symmetrically arranged. One side of the two limited push plates 64 is hinged with a clamping push plate 65, and the outer walls of the two clamping push plates 65 are fixedly installed with a supporting spring 66, and the supporting spring 66 is fixedly installed on the outer wall of the limited push plate 64;

[0044] A top pressure plate 67 is connected to one side of the two clamping push plates 65, and a rubber plate 68 is fixedly installed on the outer wall of the two top pressure plates 67. The two rubber plates 68 fit together with the outer wall of the second pipe 2, and the two top pressure plates 67 drive the rubber plate 68 to fit with the outer wall of the second pipe 2 that has entered the middle position, and squeeze the outer wall of the second pipe 2 under the support of the clamping push plates 65 and the support springs 66. Then, when the limiting push plate 64 is pushed by the associated plate 61, the limiting push plate 64 can drive the clamping push plates 65 on both sides so that the second pipe 2 is simultaneously subjected to the thrust in the same direction, so that the interface between the second pipe 2 and the first pipe 1 can fit tightly and facilitate the installation of the fixed structure of the interface.

[0045] During the specific implementation, the two top pressure plates 67 drive the rubber plate 68 to fit the outer wall of the second pipe 2 entering the middle position, and squeeze the outer wall of the second pipe 2 under the support of the clamping push plate 65 and the support spring 66. Then, when the limiting push plate 64 is pushed by the connecting plate 61, the limiting push plate 64 can drive the clamping push plates 65 on both sides so that the second pipe 2 is simultaneously subjected to the thrust in the same direction, so that the interface between the second pipe 2 and the first pipe 1 can fit tightly and facilitate the installation of the fixed structure of the interface.
