That is, the pipelines are kept stable in their original positions through a suspension protection system, thereby extending the service life of the pipelines. This protection method has been widely used in recent years.

[0042] Referring to Figure 1 , 2 , 3, a suspension protection device for pipelines crossing trenches, including a pipe trench 1 with the exposed pipeline after excavation, and two I-beams 2 with a length greater than the opening diameter of the pipe trench 1 are erected on the upper part of the pipe trench 1. The outer surface of the I-beam 2 is attached to and slidable on the inner surface of the outer shell 3. The two side surfaces of the inner cavity of the outer shell 3 are connected to the two side surfaces of several rollers 4 in a rotating manner. The several rollers 4 are respectively arranged on the upper surface of the I-beam 2 and on both sides of the outer surface of the middle part of the I-beam 2, and the I-beam 2 is clamped in the middle in a triangular shape.

[0043] The middle part of the lower surface of one side of the outer shell 3 is fixedly connected to the upper surface of the slot 7. The two sides of the slot 7 are movably penetrated by two symmetrically arranged bolts 8. The inner cavity surface of the slot 7 is attached to the outer surface of the vertical hanging rod 9. The vertical hanging rod 9 is inserted into the inner cavity of the slot 7, and the two sides of the vertical hanging rod 9 are also movably penetrated by the bolts 8. The positions where the vertical hanging rod 9 and the slot 7 are movably penetrated by the bolts 8 are the same, and the holes of the vertical hanging rod 9 and the slot 7 are communicated. A plurality of through positioning holes 13 are opened on the surface of the entire vertical hanging rod 9, and all the positioning holes 13 can be penetrated by the bolts 8. The lower part of the vertical hanging rod 9 is fixedly connected to the hanging plate 12 capable of lifting the pipeline through the bolts 8.

[0044] A suspension ring 10 capable of tying a steel wire rope is fixedly provided on the lower surface of one side of the outer shell 3, and the suspension ring 10 is located on the same side as the slot 7. Four limit grooves 11 are opened on the inner walls of both sides of the outer shell 3, and the four limit grooves 11 are oppositely arranged. One end of the spring 6 is fixedly connected to the middle part of the lower surface of the inner cavity of the four limit grooves 11, and the end of the spring 6 far from the lower surface of the limit groove 11 is fixedly connected to the lower surface of one side of the roller 4.

[0045] Through the above arrangement, the outer shell 3 fits with the I-beam 2 so that the outer shell 3 can move smoothly on the surface of the I-beam 2, and the rollers 4 inside the outer shell 3 are arranged in a herringbone shape on the upper part and both sides of the middle part of the I-beam 2, which can ensure the smooth operation of the outer shell 3 and the connection between the outer shell 3 and the I-beam 2 will not fall off, and the four limit grooves 11 cooperate with the spring 6 to ensure the passability of the roller 4 and the outer shell 3 when the roller 4 encounters uneven places on the surface of the I-beam 2, and the slot 7 cooperates with the vertical hanger 9 to lift the hanging plate 12 to suspend and protect the pipeline, and the positioning hole 13 is opened on the vertical hanger 9 to enable the hanging plate 12 to be adjusted according to different situations.

[0046] Reference Figure 4 , 5 , 6. An extension mechanism 5 is provided on one side of one of the rollers 4 on the upper surface of the I-beam 2, and the extension mechanism 5 includes a first transverse connecting rod 51 rotatably arranged on one side of the inner wall of the shell 3, and a fixing rod 58 movably penetrates one side of the first transverse connecting rod 51, and the surface of the fixing rod 58 away from the first transverse connecting rod 51 is fixedly connected to the inner wall surface of the shell 3, and the side of the first transverse connecting rod 51 away from the fixing rod 58 is fixedly connected to the limiting rods 59 protruding to both sides, and the outer surfaces of both ends of the limiting rod 59 are respectively transferred to the inner surfaces of the through holes on one side of the two first vertical connecting rods 52, and the outwardly protruding part of the limiting rod 59 is exactly consistent with the through hole diameter of the first vertical connecting rod 52, and the outer width is slightly wider and expands a little outward to limit the first vertical connecting rod 52, and the first vertical connecting rod 52 is arranged at a right angle to the first transverse connecting rod 51.

[0047] The first vertical link 52 is movably connected to the second transverse link 53 on the side away from the first transverse link 51, and the connection also uses a limit rod 59 as a connecting component, and the middle part of the second transverse link 53 is movably penetrated by the fixing rod 58, and the surface of the fixing rod 58 on the side away from the second transverse link 53 is also fixedly connected to the inner wall surface of the shell 3, and the second transverse link 53 is movably connected to one end of the second vertical link 54 on the side away from the first vertical link 52, and the connection is still limited by the limit rod 59, and the second vertical link 54 is also movably connected to the through hole at one end of the rocker 55 through the limit rod 59 on the side away from the second transverse link 53, and the middle part of the rocker 55 is also movably penetrated by the fixing rod 58, and the surface of the fixing rod 58 on the side away from the rocker 55 is fixedly connected to the inner wall surface of the shell 3.

[0048] The rocker arm 55 is fixedly connected to the surface of one side of the second vertical connecting rod 54 with the surface of one side of the clamping buckle 56, and the upper part of the clamping buckle 56 can be clamped and limited with the surface of one side of the upper part of the shell 3, and the clamping point between the clamping buckle 56 and the surface of the shell 3 is set as an inclined surface on the upper surface for convenient sliding, and the lower end is set as a plane that can play a limiting role, and a brake ring 57 is fixed in the middle of the upper surface of the first transverse connecting rod 51, and the inner surface of the brake ring 57 is a rough frosted surface, which can rub with the outer surface of the roller 4 to limit the position.

[0049] Through the above arrangement, the rocker arm 55 moves upward so that the clamping buckle 56 is clamped with the shell 3, and the fixed rod 58 movably arranged in the middle of the rocker arm 55 provides support in the middle, so the upward movement of one end of the rocker arm 55 can drive the second vertical connecting rod 54 connected to the other end to move downward, and the downward movement of the second vertical connecting rod 54 drives one end of the second transverse connecting rod 53 connected to the other end thereof to move downward at the same time. Similarly, through the action of the fixed rod 58 arranged in the middle, the other end of the second vertical connecting rod 54 moves upward with the first vertical connecting rod 52, and the upward movement of the first vertical connecting rod 52 can drive one end of the first transverse connecting rod 51 to move upward together, and the other end of the first transverse connecting rod 51 is limited by the fixed rod 58, so the first transverse connecting rod 51 can bring the brake ring 57 to approach the roller 4 and fit with the surface of the roller 4, thereby realizing the braking limit of the roller 4.

[0050] The implementation principle of a suspension protection device for a pipeline crossing a trench in the embodiment of the present application is as follows: after placing the I-beam 2 on the upper part of the pipe trench 1 and aligning it with the pipeline exposed on the soil surface, the hanging plate 12 is placed on the lower part of the pipeline, and then the vertical hanging rod 9 is installed at the four corners of the hanging plate 12, and then the shell 3 is moved to align the slot 7 with the vertical hanging rod 9 and insert the vertical hanging rod 9 into the slot 7, and the bolt 8 is screwed on so that the hanging plate 12 can play a role in suspending and protecting the pipeline, and then the position of the shell 3 on the I-beam 2 is adjusted so that the hanging plate 12 is in the best position at the lower part of the pipeline, and then the rocker 55 is moved upward to make the clamping buckle 56 engage with the shell 3 ... The second vertical connecting rod 54 connected at the other end moves downward, and the downward movement of the second vertical connecting rod 54 drives one end of the second transverse connecting rod 53 connected to the other end thereof to move downward at the same time, and the other end of the second vertical connecting rod 54 moves upward with the first vertical connecting rod 52, and the upward movement of the first vertical connecting rod 52 can drive one end of the first transverse connecting rod 51 to move upward together, and the other end of the first transverse connecting rod 51 is restricted by the fixed rod 58, so the first transverse connecting rod 51 can bring the brake ring 57 to approach the roller 4 and fit with the surface of the roller 4, thereby realizing the braking limit of the roller 4, so that the shell 3 will not move arbitrarily on the I-beam 2.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
