Description

Technical Field

[0001] This utility model relates to a protection structure for municipal road pipelines, and to the field of pipeline protection technology, specifically a protection structure for municipal road pipelines. Background Technology

[0002] The main purpose of municipal road pipeline protection structures is to ensure the safety of underground pipelines during municipal road construction and to prevent pipeline damage or disruption to their normal use caused by construction.

[0003] Since the size of the protective structure is predetermined, it may not be able to fully adapt to the needs of pipelines with different diameters and burial depths. Furthermore, when encountering pipelines with non-standard sizes or special layouts, the fixed-size protective structure may not be effectively applied, resulting in poor flexibility and adaptability. In addition, if the protection of municipal road pipelines is not treated with shock absorption and buffering, the bolted connections may gradually loosen due to vibration, leading to loose pipeline connections and affecting the normal operation of the pipelines. Utility Model Content

[0004] This utility model provides a protection structure for municipal road pipelines. One purpose is to provide an adjustable function to solve the problem of poor adaptability of the protection structure. Another purpose is to solve the problem that vibration will affect the operation of pipelines, so as to extend the service life of pipelines.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A municipal road pipeline protection structure includes a base, a cover plate rotatably connected to the top of the base, and two fixing devices fixedly connected inside the base.

[0007] A further improvement of the present invention is that a support plate is fixedly connected to the top of the base, a bracket is fixedly connected to the bottom of the cover plate and snapped into the support plate, and a dust cover is fixedly connected to the left side of the cover plate.

[0008] A further improvement of the present invention is that: a ratchet is fixedly connected to the top of the base, and a pawl is fixedly connected to the left and right sides of the ratchet. Several rubber pads are fixedly connected to the top of the base, and two guide rails are fixedly connected to the top of the rubber pads. The two guide rails are located on the front and rear sides of the ratchet. Several slides are slidably connected to the top of the two guide rails. A pawl is slidably connected to the bottom of each slide, and each pawl engages with the ratchet.

[0009] A further improvement of the present invention is that the fixing device includes a support plate, a ratchet 2 is fixedly connected to the lower part of the support plate, a plurality of rubber pads 2 are fixedly connected to the lower part of the support plate and two guide rails 2 are fixedly connected to the lower part of the support plate, the two guide rails 2 are respectively located on the front and rear sides of the ratchet 2, the two guide rails 2 are slidably connected to the slide table below them, a pawl 2 is slidably connected above each slide table, each pawl 2 is engaged with the ratchet 2, and a pawl 3 is fixedly connected to the right side of each slide table.

[0010] A further improvement of the present invention is that: a spring is fixedly connected to the inner side of each pawl 2 and pawl 1; a connecting rod is rotatably connected to the left side of each pawl 2 and pawl 1; and a push rod is slidably connected between each slide and pawl 2 and pawl 1, with the upper and lower ends of the push rod respectively rotatably connected to a connecting rod.

[0011] A further improvement of this utility model is that: a push plate is fixedly connected to the push rod behind the slide table, and sliders are fixedly connected to the push rod around the push plate and slidably connected to the slide table; four claws are fixedly connected to the left side of the slide table.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a protection structure for municipal road pipelines. When it is necessary to fix pipelines of different sizes, different pipelines are inserted between the slides. Then, the slides are moved to the left, so that the distance between the fourth pawl on the slide and the third pawl on its left side is reduced, thus clamping the pipeline. When the second and first pawls move to the left away from the current ratchet, they are gradually pushed towards the slide by the second and first ratchet bars, and the spring is compressed. When the second and first pawls move to the next ratchet bar, the spring rebounds and pushes the second and first pawls towards the first and second ratchet bars, thus locking the second and first pawls. This solves the problem of poor adaptability of the protection structure.

[0014] 2. This utility model provides a protection structure for municipal road pipelines. When the cover plate and base vibrate, the support plate and base will first transmit the vibration to rubber pad one and rubber pad two. Rubber pad one and rubber pad two absorb and dissipate vibration energy through the elastic deformation of rubber, reducing the vibration transmitted to the pipeline and solving the problem that vibration will affect the operation of the pipeline.

[0021] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0022] like Figure 1 As shown, this utility model provides a protection structure for municipal road pipelines, including a base 1, a cover plate 2 rotatably connected to the top of the base 1, and two fixing devices 3 fixedly connected inside the base 1. After the pipeline is fixed by the fixing devices 3, the cover plate 2 above the base 1 prevents mud and sand from falling into the fixing devices 3 and affecting the sliding of the slide 36 on the fixing devices 3.

[0023] like Figure 2 As shown, this utility model provides a technical solution: a support plate 5 is fixedly connected to the upper part of the base 1, a bracket 4 is fixedly connected to the lower part of the cover plate 2 and is snapped into the support plate 5, and a dust cover 6 is fixedly connected to the left side of the cover plate 2. When the cover plate 2 is closed, the support plate 5 snaps into the bracket 4 so that the cover plate 2 is fixed on the base 1. The dust cover 6 prevents mud and sand from falling into the rotational connection between the cover plate 2 and the base 1 and affecting the rotation of the cover plate 2.

[0024] like Figure 3As shown, this utility model provides a technical solution: a ratchet 31 is fixedly connected to the top of the base 1, and pawls 35 and 37 are fixedly connected to the left and right sides of the ratchet 31 respectively. Several rubber pads 32 are fixedly connected to the top of the base 1, and two guide rails 33 are fixedly connected above the rubber pads 32. The two guide rails 33 are located on the front and rear sides of the ratchet 31 respectively. Several slides 36 are slidably connected above the two guide rails 33. A pawl 34 is slidably connected below each slide 36, and each pawl 34 engages with the ratchet 31. When... When different sizes of pipelines need to be fixed, the different pipelines are inserted between the slides 36, and then the slides 36 are moved to the left, so that the distance between the fourth pawl 314 on the slides 36 and the third pawl 313 on its left side is reduced, clamping the pipeline. When the second pawl 311 and the first pawl 34 move to the left away from the current ratchet, they are gradually pushed towards the slides 36 by the second pawl 310 and the first pawl 31, and the spring 315 is compressed. When the second pawl 311 and the first pawl 34 move to the next ratchet, the spring 315 rebounds and pushes the second pawl 311 and the first pawl 34 towards the first pawl 31 and the second pawl 310.

[0025] like Figure 4 As shown, this utility model provides a technical solution: the fixing device 3 includes a support plate 39, a second ratchet 310 is fixedly connected to the lower part of the support plate 39, a plurality of second rubber pads 38 are fixedly connected to the lower part of the support plate 39, and two second guide rails 312 are fixedly connected to the lower part of the support plate 39. The two guide rails 312 are located on the front and rear sides of the second ratchet 310 respectively. The two guide rails 312 are slidably connected to the slide table 36 below them. A second pawl 311 is slidably connected to the upper part of each slide table 36. Each second pawl 311 is engaged with the second ratchet 310. A third pawl 313 is fixedly connected to the right side of each slide table 36. When the second pawl 311 and the first pawl 34 move to the right, the second pawl 310 and the first pawl 31 will respectively engage the second pawl 311 and the first pawl 34, so that the slide table 36 can only move in one direction.

[0026] like Figure 5As shown, this utility model provides a technical solution: a spring 315 is fixedly connected to the inner side of each pawl 2 311 and pawl 1 34; a connecting rod 316 is rotatably connected to the left side of each pawl 2 311 and pawl 1 34; a push rod 317 is slidably connected between each slide 36 and pawl 2 311 and pawl 1 34; the upper and lower ends of the push rod 317 are respectively rotatably connected to a connecting rod 316; and a push rod 317 is fixedly connected to the rear of the slide 36. Plate 318 and push plate 318 are fixedly connected to sliders 319 around push rod 317 and are slidably connected to slide table 36. A pawl 4 314 is fixedly connected to the left side of slide table 36. When it is necessary to release the pipeline, press push plate 318 to push push rod 317. Then push rod 317 pulls pawl 2 311 and pawl 1 34 away from ratchet 2 310 and ratchet 1 31 through connecting rod 316, and disengages from jamming. At this time, slide table 36 can be moved to the right to release the pipeline.

[0027] The working principle of this municipal road pipeline protection structure will be explained in detail below.

[0028] like Figure 1-5 As shown,

[0029] When it is necessary to fix pipelines of different sizes, insert the different pipelines between the slides 36, and then move the slides 36 to the left, so that the distance between the fourth pawl 314 on the slides 36 and the third pawl 313 on its left side is reduced, clamping the pipeline. As the second pawl 311 and the first pawl 34 move to the left away from the current ratchet, they are gradually pushed towards the slides 36 by the second ratchet 310 and the first ratchet 31, compressing the spring 315. When the second pawl 311 and the first pawl 34 move to the next ratchet, the spring 315 rebounds and pushes the second pawl 311 and the first pawl 34 towards the first ratchet 31 and the second ratchet 310. When the second pawl 311 and the first pawl 34 move to the right, the second ratchet 310 and the second ratchet 310 push the second pawl 311 and the first pawl 34 towards the ratchet 31 and the second ratchet 310. The first pawl 31 will lock the second pawl 311 and the first pawl 34 respectively, so that the slide table 36 can only move in one direction. When it is necessary to release the pipeline, press the push plate 318 to push the push rod 317. Then the push rod 317 pulls the second pawl 311 and the first pawl 34 away from the second pawl 310 and the first pawl 31 through the connecting rod 316, and releases them from the jam. At this time, the slide table 36 can be moved to the right to release the pipeline. When the cover plate 2 and the base 1 vibrate, the support plate 39 and the base 1 will first transmit the vibration to the first rubber pad 32 and the second rubber pad 38. The first rubber pad 32 and the second rubber pad 38 absorb and dissipate the vibration energy through the elastic deformation of the rubber, reducing the vibration transmitted to the pipeline.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
