[0028] For the purpose of facilitating the understanding of the present application, the present application will be described more fully below and preferred embodiments of the present application will be given. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terminology used in the description of the present application herein only for the purpose of describing specific embodiments and is not intended to limit the present application.

[0030] Embodiment:

[0031] Referring to Figures 1-7 The present embodiment provides a pipeline installation roller bracket, comprising a fixed frame 1, a sliding frame 2 and a roller assembly 3, the sliding frame 2 is slidingly connected to the fixed frame 1, and the sliding frame 2 is slidingly arranged along the length direction of the fixed frame 1; the roller assembly 3 comprises a first roller 31 and a second roller 32, the first roller 31 and the second roller 32 are both rotatably connected to the sliding frame 2, and the first roller 31 and the second roller 32 are arranged in a V shape.

[0032] It is found through research that when the existing pipeline is laid, a roller support needs to be built first, and the roller support is built beside the pipeline trench where the pipeline is laid. During the placing process of the built roller support, it is difficult for multiple roller supports to be laid on the same straight line, that is, misalignment between the roller supports is easily caused. When the pipeline moves on the roller support, shear force along the width direction of the pipeline is generated between the pipeline and the misaligned roller, thereby increasing the frictional resistance between the pipeline and the roller support. The traction machinery for pulling the pipeline needs to have greater power to pull the pipeline to move on the roller bracket, and the energy consumption is high.

[0033] It can be known that through the arrangement of the sliding frame 2 and the fixed frame 1, when laying the roller bracket, the fixed frame 1 is laid beside the pipeline ditch for laying the pipeline, and the fixed frame 1 is laid perpendicular to the pipeline ditch or approximately perpendicular to the pipeline ditch, and then the sliding frame 2 is slidably connected to the fixed frame 1. It should be noted that a plurality of roller supports need to be arranged beside the pipeline ditch along the length direction of the pipeline ditch in advance during the pipeline laying process. That is, a plurality of fixed frames 1 are laid beside the pipeline ditch along the length direction of the pipeline ditch, and the corresponding sliding frames 2 are slidably connected to the fixed frames 1. It can be known that the plurality of fixed frames 1 are not on the same straight line when laying the fixed frame 1, and the sliding frames 2 are also not on the same straight line. Taking three roller brackets arranged along the pipeline as an example, when conveying the pipeline, the pipeline is sequentially overlapped on the first roller 31 and the second roller 32 of the sliding frame 2. Initially, the three sliding frames 2 are not on the same straight line, which will generate a shear force along the width direction of the pipeline on the pipeline. Because the shear force is a mutual force, the shear force also acts on the sliding frame 2, and under the action of the shear force, the corresponding sliding frame 2 will slide on the fixed frame 1, thereby automatically adjusting the position of the sliding frame 2, and finally making the three sliding frames 2 arranged along the length direction of the pipeline ditch on the same straight line. At this time, the shear force acting on the pipeline disappears, and the frictional resistance during the conveying of the pipeline is greatly reduced, so that the pipeline is more smooth during the conveying process, and the traction machine can move the pipeline on the roller bracket with smaller force, thereby greatly reducing the power consumption of the traction machine and saving energy.

[0034] Further, the first roller 31 comprises a first wheel body 311 and a first protective layer 312, both ends of the first wheel body 311 are rotatably connected to the sliding frame 2 through bearings, and the first protective layer 312 is arranged around the outer surface of the first wheel body 311; the second roller 32 comprises a second wheel body 321 and a second protective layer 322, both ends of the second wheel body 321 are rotatably connected to the sliding frame 2 through bearings, and the second protective layer 322 is arranged around the outer surface of the second wheel body 321.

[0035] Specifically, the first protective layer 312 and the second protective layer 322 are both flexible layers, that is, the first protective layer 312 and the second protective layer 322 are both made of materials with soft texture such as rubber, silicone, polyurethane, etc. The first protective layer 312 is adhered to the outer surface of the first wheel body 311 by adhesive, and the second protective layer 322 is also adhered to the outer surface of the second wheel body 321 by adhesive.

[0036] It can be known that the arrangement of the first protective layer 312 and the second protective layer 322 protects the pipeline, prevents damage to the paint or other protective layer on the surface of the pipeline, and reduces damage to the pipeline during the conveying process.

[0037] Further, the sliding frame 2 comprises a sliding base 21, a first sliding block 22 and a second sliding block 23, the first sliding block 22 is arranged to slide along the length direction of the sliding base 21, the second sliding block 23 is arranged to slide along the length direction of the sliding base 21, and the first sliding block 22 is arranged to be staggered relative to the second sliding block 23; the first roller 31 is rotatably connected to the first sliding block 22, and the second roller 32 is rotatably connected to the second sliding block 23.

[0038] It can be known that, by sliding the first sliding block 22 and the second sliding block 23 on the sliding base 21, the first roller 31 is away from or close to the second roller 32, the distance between the first roller 31 and the second roller 32 is adjusted, so that the V-shaped support structure formed by the first roller 31 and the second roller 32 can adapt to the pipe conveying of different sizes. And by arranging the first sliding block 22 and the second sliding block 23 to be staggered, interference between the first sliding block 22 and the second sliding block 23 during sliding is avoided.

[0039] Further, the sliding frame 2 further comprises a first lead screw 24, a first driving member 25, a second lead screw 26 and a second driving member 27, the first lead screw 24 is rotatably connected to the sliding base 21, and the first lead screw 24 is arranged along the length direction of the sliding base 21, the first driving member 25 is coaxially connected to the end of the first lead screw 24, the first lead screw 24 penetrates through the first sliding block 22 and is threadedly connected with the first sliding block 22; the second lead screw 26 is rotatably connected to the sliding base 21, and the second lead screw 26 is arranged along the length direction of the sliding base 21, the second driving member 27 is coaxially connected to the end of the second lead screw 26, the second lead screw 26 penetrates through the second sliding block 23 and is threadedly connected with the second sliding block 23.

[0040] It can be known that, by driving the first lead screw 24 to rotate through the first driving member 25, the first sliding block 22 is driven to slide along the length direction of the sliding frame 2, and in turn the first roller 31 is driven to slide along the length direction of the sliding frame 2, by driving the second lead screw 26 to rotate through the second driving member 27, the second sliding block 23 is driven to slide along the length direction of the sliding frame 2, and in turn the second roller 32 is driven to slide along the length direction of the sliding frame 2, the mutual distance between the first roller 31 and the second roller 32 is adjusted.

[0041] Further, the first driving member 25 and the second driving member 27 are arranged to be staggered.

[0042] It can be known that, by arranging the first driving member 25 and the second driving member 27 to be staggered, interference between the first driving member 25 and the second driving member 27 is prevented, or the first driving member 25 and the second driving member 27 are prevented from being too close to hinder operation.

[0043] It should be noted that in the present embodiment, the first driving member 25 and the second driving member 27 are both hand wheels, and the hand wheels are respectively distributed at both ends of the sliding frame 2, and the hand wheels are driven to rotate by hand to drive the corresponding first lead screw 24 or the second lead screw 26 to rotate, thereby driving the corresponding first sliding block 22 or the second sliding block 23 to move. In some other embodiments of the present application, the hand wheels can also be arranged on the same side of the sliding frame 2, and the two hand wheels are arranged staggered with each other to facilitate operation. In some other embodiments, the first driving member 25 can also be a micro motor or other component or structure capable of driving the first lead screw 24 or the second lead screw 26 to rotate.

[0044] Further, support rollers 28 are arranged at both sides of the sliding frame 2, and the support rollers 28 are arranged to roll along the length direction of the fixed frame 1. The fixed frame 1 is provided with tracks 29, and the support rollers 28 are rollingly connected to the tracks 29.

[0045] It can be known that, by arranging the support rollers 28, the sliding friction between the sliding frame 2 and the fixed frame 1 is changed to rolling friction, and the resistance of the rolling friction is smaller than that of the sliding friction. Therefore, by arranging the support rollers 28, the friction between the sliding frame 2 and the fixed frame 1 can be reduced, so that the sliding frame 2 can be more easily moved on the fixed frame 1.

[0046] Specifically, the support rollers 28 are arranged at four corners of the sliding frame 2 to stably support the sliding frame 2, and the tracks 29 are arranged in two parallel tracks arranged along the length direction of the sliding frame 2. Of course, in some other embodiments, more support rollers 28 can be provided, and the support rollers 28 are arranged at both sides of the sliding frame 2, and the support rollers 28 at both sides are rollingly connected to the corresponding tracks 29.

[0047] Further, the buckle 4 is detachably connected to the fixed frame 1, and the support roller 28 is provided with a limiting groove 281 arranged along the outer periphery of the support roller 28, and the buckle 4 is embedded in the limiting groove 281.

[0048] It can be known that, by arranging the buckle 4 and the limiting groove 281 on the support roller 28, the movement of the support roller 28 is guided to prevent the support roller 28 from being separated from the track 29, thereby reducing the failure rate of the roller carrier during use. Secondly, when the sliding frame 2 and the fixed frame 1 need to be disassembled, the corresponding buckle 4 can be removed to move the sliding frame 2 away from the fixed frame 1.

[0049] Further, the wing plate 5 is fixedly connected to the fixed frame 1, the bottom of the wing plate 5 is flush with the bottom of the fixed frame 1, and the wing plate 5 extends along the width direction of the fixed frame 1.

[0050] It can be seen that by arranging the wing plates 5, the fixing frame 1 is widened, thereby improving the anti-tipping ability of the fixing frame 1.

[0051] Furthermore, it also includes a reinforcing rib 6, the first end of which is fixedly connected to the fixing frame 1, and the second end of which is fixedly connected to the wing plate 5.

[0052] It is known that the connection between the wing plate 5 and the fixed frame 1 is strengthened by the reinforcing rib 6, thereby improving the deformation resistance of the wing plate 5.

[0053] Furthermore, it also includes a handle 7, which is fixedly connected to the wing plate 5.

[0054] It is understood that by setting handle 7, when the fixed seat needs to be moved, it can be moved manually by using handle 7, or it can be lifted by hoisting equipment, which facilitates handling. Specifically, there are two wing plates 5, and two handles 7 are arranged on each wing plate 5.

[0055] The working process and principle of this utility model are as follows:

[0056] Before laying the pipe, the fixing frame 1 is placed along the pipe trench. During placement, it can be moved manually by lifting using the handle 7 on the wing plate 5. During placement, the direction of the track 29 of the fixing frame 1 is perpendicular to the direction of the pipe trench. Multiple fixing frames 1 are placed at equal intervals along the length of the pipe trench, and the multiple fixing frames 1 are initially kept in a straight line. The sliding frame 2 is installed on the fixing frame 1 accordingly, and the fastener 4 is installed on the fixing frame 1 to limit the support roller 28 of the sliding frame 2 and prevent the support roller 28 from falling off the track 29 of the fixing frame 1. At this time, the sliding frame 2 can slide freely on the fixing frame 1. The first roller 31 and the second roller 32 are installed on each sliding frame 2. The first drive component 25 and the second drive component 27 are adjusted according to the diameter of the pipe to drive the first slider 22 and the first roller 31, as well as the second slider 23 and the second roller 32, to move relative to the slide seat 21 until the V-shaped structure formed by the first roller 31 and the second roller 32 matches the diameter of the pipe to be transported. During pipeline transport, the pipeline is sequentially connected to the first roller 31 and the second roller 32 on the sliding frame 2, which support the pipeline. When multiple sliding frames 2 arranged along the pipeline trench are not on the same straight line, a shearing force is generated on the pipeline. This shearing force reacts on the sliding frames 2, causing them to move relative to the fixed frame 1 until the multiple sliding frames 2 move to the same straight line, at which point the shearing force disappears. This reduces the friction between the first roller 31 and the pipeline, and between the second roller 32 and the pipeline, when the pipeline is transported on the first roller 31 and the second roller 32.

[0057] The above merely describes preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
