Description

Technical Field

[0001] The utility model relates to the field of brackets, and particularly relates to an oil pipeline bracket. Background Technique

[0002] An oil pipeline is a pipeline system that transports oil and its products from the production site to the processing plant or end users. These pipelines are mainly composed of oil pipelines, oil transfer stations, and other auxiliary related equipment. They are one of the main equipment in the oil storage and transportation industry. Oil pipelines are generally steel pipes, which are connected into long-distance pipelines using connection devices such as welding and flanges. When installing the pipeline, brackets need to be installed to ensure the equipment that supports and fixes the pipeline, prevent the pipeline from sagging, bending, or vibrating, reduce pipeline stress, protect the pipeline from damage, improve pipeline stability and safety, extend the service life of the pipeline, reduce energy consumption and maintenance costs, and ensure the smooth progress of oil transportation work.

[0003] The existing Chinese patent publication number is: CN108105470B, which discloses an oil pipeline bracket, including a support base. A support sleeve rod is fixedly installed on the top of the support base. The inner cavity side walls of the support sleeve rod are both provided with a first chute. A slide rail is fixedly installed in the chute. On the opposite sides of the slide rail, two turntables are movably installed. The center of the turntable is fixedly connected to the output shaft of the drive motor. Above the turntable, two fixed collar rings are fixedly installed on the rear side wall of the inner cavity of the support sleeve rod. For this oil pipeline bracket, by setting the movable push rod, the drive motor drives the turntable to rotate. The turntable is oval. When the turntable rotates to the longer end and contacts the movable push rod, it pushes the movable push rod to move upward, thereby adjusting the distance between the support rod and the support sleeve rod, and conveniently adjusting the support height of the bracket according to the different installation terrains of the oil pipeline, which is very convenient to use.

[0004] The above installation bracket still has the following problems when in use: The above installation bracket can only limit the installation of the lower end of the oil pipeline during use, and cannot limit the installation of the upper end of the oil pipeline. This may cause the oil pipeline to become loose after installation, affecting the service life of the oil pipeline.

[0005] Therefore, it is very necessary to invent an oil pipeline bracket to solve the above problems. Content of the Utility Model

[0006] The purpose of the utility model is to provide an oil pipeline bracket to solve the problem that the above installation bracket can only limit the installation of the lower end of the oil pipeline during use, and cannot limit the installation of the upper end of the oil pipeline. This may cause the oil pipeline to become loose after installation, affecting the service life of the oil pipeline as mentioned in the above background technique.

[0007] To achieve the above object, the utility model provides the following technical solutions: An oil pipeline support, including a bottom support. A pipeline main body is placed in the top arc groove of the bottom support. An activity cavity is opened inside the bottom support. Both ends of the activity cavity are communicated with two symmetrically arranged channels. The channels are located inside the bottom support. A first fixing rod is fixedly connected to the inner wall of the channel. A clamping plate is rotatably connected to the outer ring of the first fixing rod. The clamping plate clamps and limits the pipeline main body. It further includes:

[0008] A driving assembly, including a motor. A motor groove is arranged on one side of the bottom support. The motor is fixedly connected to the inner wall of the motor groove. The output shaft of the motor is drivingly connected to a driving shaft. The driving shaft is rotatably connected to the inner wall of the activity cavity through a bearing. A moving block is threadedly connected to the outer ring of the driving shaft. A connecting rod is rotatably connected to the inside of the moving block. The connecting rod is in a sliding connection state with the clamping plate.

[0009] Preferably, the clamping plate is composed of an arc plate and a vertical plate connected to the arc plate. The arc plate and the vertical plate are integrally installed. The first fixing rod is located at the connection position of the arc plate and the vertical plate. A cushion block is fixedly connected to the inner wall of the arc plate. The cushion block is in contact with the outer wall of the pipeline main body to ensure the fitting installation of the clamping plate and the cushion block with the pipeline main body.

[0010] Preferably, a limiting block is fixedly connected to the side wall of the vertical plate. The limiting block is in contact with the inner wall of the activity cavity.

[0011] Preferably, a torsion spring is sleeved on the outer ring of the first fixing rod. Both ends of the torsion spring are respectively fixedly connected to the clamping plate and the inner wall of the activity cavity. The torsion spring applies a force to the clamping plate in the direction towards the pipeline main body to perform secondary fastening on the pipeline main body.

[0012] Preferably, two sections of threads are arranged on the outer ring of the driving shaft. The two sections of threads have opposite helix directions;

[0013] Two symmetrically arranged moving blocks are provided. The two moving blocks are respectively threadedly connected to the two sections of threads. The side wall of the moving block is in contact with and slidably connected to the inner wall of the activity cavity. When the driving shaft rotates, the two moving blocks move linearly towards or away from each other synchronously, thereby driving the clamping plate to move towards or away from each other to clamp or release the pipeline main body.

[0014] Preferably, a notch is opened at the top of the moving block. A second fixing rod is fixedly connected to the inner wall of the notch. A connecting rod is rotatably connected to the outer ring of the second fixing rod through a bearing. When the moving block moves, the connecting rod synchronously changes its angle, thereby driving the clamping plate to change its angle to clamp or loosen the pipeline main body, facilitating the installation and disassembly of the pipeline main body and the bottom support.

[0015] Preferably, the outer wall of the upper end of the connecting rod is attached to and slidably connected to the inner wall of the vertical groove provided inside the vertical plate. In this way, when the moving plate moves to drive the connecting rod to change the angle, the connecting rod can synchronously drive the clamping plate to change the angle, thereby limiting and installing the pipeline main body, and at the same time ensuring the movable connection between the clamping plate and the connecting rod.

[0016] In the above technical solution, the technical effects and advantages provided by the present utility model are as follows:

[0017] By starting the motor to drive the rotation of the threaded drive shaft, two symmetrically arranged moving blocks move towards each other, and at the same time, the connecting rods rotatably connected to the moving blocks are synchronously inclined, thereby driving the clamping plates slidably connected to the connecting rods to synchronously incline and move, which is convenient for the operator to take and place the bottom bracket. In this way, it is more convenient to disassemble and assemble the pipeline main body and the bottom bracket. The overall operation is convenient, and the bottom bracket can be reused multiple times.

[0025] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0026] The present utility model provides a petroleum pipeline support as shown in Figures 1-4 Figure 1, including a bottom support 1. A pipeline main body 9 is placed in the top arc-shaped groove of the bottom support 1. An activity cavity 2 is opened inside the bottom support 1. The two ends of the activity cavity 2 are communicated with two symmetrically arranged channels 3. The channels 3 are located inside the bottom support 1. A first fixing rod 4 is fixedly connected to the inner wall of the channel 3. A clamping plate 5 is rotatably connected to the outer ring of the first fixing rod 4. The clamping plate 5 clamps and limits the pipeline main body 9. It further includes:

[0027] A driving component 7, including a motor 701. A motor groove is arranged on one side of the bottom support 1. The motor 701 is fixedly connected to the inner wall of the motor groove. The output shaft of the motor 701 is in transmission connection with a driving shaft 702. The driving shaft 702 is rotatably connected to the inner wall of the activity cavity 2 through a bearing. A moving block 704 is threadedly connected to the outer ring of the driving shaft 702. A connecting rod 705 is rotatably connected to the inside of the moving block 704. The connecting rod 705 is in a sliding connection state with the clamping plate 5.

[0028] The clamping plate 5 is composed of an arc-shaped plate 501 and a vertical plate 502 connected to the arc-shaped plate 501. The arc-shaped plate 501 and the vertical plate 502 are integrally installed. The first fixing rod 4 is located at the connection position between the arc-shaped plate 501 and the vertical plate 502. A cushion block 6 is fixedly connected to the inner wall of the arc-shaped plate 501. The cushion block 6 is in contact with the outer wall of the pipeline main body 9 to ensure the fitting installation of the clamping plate 5 and the cushion block 6 with the pipeline main body 9.

[0029] A limiting block 8 is fixedly connected to the side wall of the vertical plate 502. The limiting block 8 is in contact with the inner wall of the activity cavity 2.

[0030] A torsion spring is sleeved on the outer ring of the first fixing rod 4. The two ends of the torsion spring are respectively fixedly connected to the clamping plate 5 and the inner wall of the activity cavity 2. The torsion spring applies a force to the clamping plate 5 in the direction towards the pipeline main body 9 to perform secondary fastening on the pipeline main body 9.

[0031] Two sections of threads 703 are arranged on the outer ring of the driving shaft 702. The two sections of threads 703 have opposite helix directions;

[0032] There are two symmetrically arranged moving blocks 704. The two moving blocks 704 are respectively threadedly connected to the two sections of threads 703. The side walls of the moving blocks 704 are in contact with and slidably connected to the inner wall of the activity cavity 2. When the driving shaft 702 rotates, the two moving blocks 704 perform synchronous linear movement towards each other or away from each other, thereby driving the clamping plate 5 to move towards or away from each other to clamp or release the pipeline main body 9.

[0033] A notch 706 is formed at the top of the moving block 704, and a second fixing rod 707 is fixedly connected to the inner wall of the notch 706. Moreover, a connecting rod 705 is rotatably connected to the outer circle of the second fixing rod 707 through a bearing, ensuring that when the moving block 704 moves, the connecting rod 705 synchronously changes its angle, thereby driving the clamping plate 5 to change its angle to clamp or loosen the pipe body 9, facilitating the installation and disassembly of the pipe body 9 and the bottom bracket 1.

[0034] The outer wall of the upper end of the connecting rod 705 is in contact with and slidably connected to the inner wall of the vertical groove 708 provided inside the vertical plate 502. In this way, when the moving block 704 moves to drive the connecting rod 705 to change its angle, the connecting rod 705 can synchronously drive the clamping plate 5 to change its angle to limit and install the pipe body 9, while ensuring the movable connection between the clamping plate 5 and the connecting rod 705.

[0035] Working principle: When using an oil pipeline bracket, first start the motor 701 to drive the rotation of the drive shaft 702 that is drivingly connected to the output shaft of the motor 701 and is provided with threads 703. Two symmetrically arranged moving blocks 704 that are simultaneously threadedly connected to the drive shaft 702 move towards each other under the limiting action of the movable cavity 2. At the same time, the connecting rods 705 rotatably connected to the moving blocks 704 tilt synchronously, thereby driving the clamping plates 5 slidably connected to the connecting rods 705 to tilt synchronously. The clamping plates 5 rotate away from the outer wall of the pipe body 9, facilitating the operator to pick up and place the bottom bracket 1. Similarly, when the drive shaft 702 rotates in the reverse direction, the two moving blocks 704 move away from each other, and the clamping plates 5 can move towards the pipe body 9 placed on the bottom bracket 1 to clamp and install the pipe body 9. At the same time, the contact surface amplitude between the clamping plates 5 and the pipe body 9 is relatively wide, ensuring that the installation of the pipe body 9 and the bottom bracket 1 is not likely to fall off.

[0036] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present invention.
