[0014] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0015] Reference Figure 1 and Figure 2The utility model provides a protective device for exposed pipelines in a groove, comprising a metal bracket ③, wherein the metal bracket ③ comprises a frame body and a plurality of rubber rollers ③-1 below the frame body, wherein the rubber rollers ③-1 are semicircular and are used to accommodate pipelines, wherein a cross-bracing hollow metal rod ① is arranged above the frame body, wherein a rubber rope ④ is arranged between the rubber roller ③-1 and the cross-bracing hollow metal rod ①, wherein the number of the rubber ropes ④ is three, wherein the two ends of the rubber rope ④ are fixedly connected to the two ends of the rubber roller ③-1, and the rubber rope ④ passes through a rubber ring arranged on the cross-bracing hollow metal rod ① , the rubber ring can move forward and backward on the cross brace hollow metal rod ①, and plastic longitudinal beams ② are also provided at both ends of the cross brace hollow metal rod ①. The cross brace hollow metal rod ① can move horizontally on the plastic longitudinal beam ②. In the utility model, the pipeline can be rolled and hung on the rubber roller ③-1 through the rubber rope ④, and the rubber ring ⑤ is moved horizontally. The metal bracket ③ and the pipeline are relatively horizontally displaced by the rubber rope ④, and the rubber ring ⑤ is moved longitudinally at the same time, so that the pipeline on the bracket slides on the plastic longitudinal beam ② with the cross brace hollow metal rod ①, so as to realize the pipeline protection construction structure with longitudinal displacement. The plastic longitudinal beam ② is provided with a spherical slideway, and the cross brace hollow metal rod ① can slide longitudinally on the spherical slideways of the two plastic longitudinal beams ②. The rubber rope ④ can horizontally pass through the cross brace hollow metal rod ① and the rubber ring ⑤, so that the metal bracket ③ is suspended in the air. The metal bracket ③ structure has a flexible round rubber roller ③-1, and the flexible round rubber roller ③-1 and the pipeline can be used to achieve non-damaged horizontal displacement.

[0016] By adopting the above technical solution, when in use, the cross brace hollow metal rod ① is installed on the plastic longitudinal beam ② slideway on the ground on both sides of the groove, three rubber ropes ④ are horizontally passed through the cross brace hollow metal rod ① and the rubber ring ⑤, and the pipeline on the metal bracket ③ is suspended in the air through the embedded bolts at both ends of the rubber rope ④. Then, in the process of pulling the rubber ring ⑤ horizontally, the metal bracket ③ and the pipeline are driven to have a relative horizontal displacement, and at the same time, the rubber ring ⑤ is pulled longitudinally to drive the pipeline and the metal bracket ③ to slide longitudinally with the cross brace hollow metal rod ①. The device can be used to make the pipeline move flexibly in the longitudinal and transverse directions, especially for exposed long pipelines, which can not only flexibly move the local position of the pipeline, but also move the exposed pipeline as a whole, thereby playing a protective role.

[0017] In the utility model, the plastic longitudinal beam ② is made of a hard material, and its internal sliding groove is spherical. Spherical sliders ①-1 are arranged at both ends of the hollow metal rod ① of the horizontal support. The rubber ring ⑤ is divided into an upper hand-pull large ring and a lower small ring, and the aperture directions of the large and small rings are perpendicular to each other, and the small ring can vertically pass through the hollow metal rod ① of the horizontal support. The small ring can move back and forth in the hollow metal rod ① of the horizontal support. The two ends of the rubber rope ④ can be bolted and can horizontally pass through the hollow metal rod ① of the horizontal support and the small ring. A flexible smooth round rubber roller ③-1 is installed at the bottom of the metal bracket ③.

[0018] The construction steps of this utility model are as follows:

[0019] Step 1: Dig a shallow trench until the underground pipeline is initially exposed and suspended in the air. Then, place two plastic longitudinal beams ② parallel to the foundation pit direction at stable positions on both sides of the trench, and then install the spherical sliders ①-1 at both ends of the cross-bracing hollow metal rod ① in the slide grooves of the two plastic longitudinal beams ② respectively, ensuring that the cross-bracing hollow metal rod ① is perpendicular to the trench direction;

[0020] Step 2: suspend the pipeline on the metal bracket ③ of the exposed pipeline protection device. During the excavation of earth around the exposed pipeline in the trench or the laying of a new pipeline at the bottom of the trench, the operator can pull the rubber ring ⑤ vertically and horizontally to allow the exposed pipeline to move vertically and horizontally.

[0021] Step three: After the excavation around the exposed pipeline in the trench or the laying of the new pipeline at the bottom of the trench is completed, use the device to restore the displaced exposed pipeline to its original position.

[0022] Through the above technical solution, the exposed pipelines in the groove can be well protected.

[0023] As above, although the utility model has been shown and described with reference to a specific preferred embodiment, it should not be interpreted as limiting the utility model itself. Various changes can be made to it in form and detail without departing from the spirit and scope of the utility model defined in the attached claims.
