Description

Technical Field

[0001] The utility model relates to the technical field of pipeline transportation, in particular to a fixing device for convenient transportation of steel cylinder concrete pipes. Background Art

[0002] Prestressed steel cylinder concrete jacking pipe is a pipe composed of prestressed structure and non-prestressed structure. Prestressed steel cylinder concrete jacking pipe is a composite structure composed of thin steel plate, high-strength concrete, prestressed steel wire and reinforced concrete protective layer. It is suitable for various pressure pipe jacking sections and is widely used in urban water distribution mains, thermal power plant water supply pipes, water conservancy projects, rainwater and sewage pipes, industrial water supply and wastewater pipelines, etc. The rigidity of the pipe can prevent the pipe from being damaged during lifting, transportation and installation. However, due to the smooth outer wall and thick wall of the pipe, the weight of the large-diameter jacking pipe is relatively large, which causes the jacking pipe to slide and collide during transportation, which can easily cause damage to the pipe and affect the transportation efficiency.

[0003] For example, Chinese patent publication No. CN213650634U discloses a fixing device for transporting prestressed steel cylinder concrete jacking pipes. When in use, since springs and silencers are arranged on the base and the load-bearing seat, when bumps occur during transportation, the springs can alleviate the impact force generated by the up and down sliding of the prestressed jacking pipe, and the silencers can reduce the collision sound generated by the prestressed jacking pipe during transportation. At the same time, it can also further alleviate the collision impact force generated by the prestressed jacking pipe during transportation to avoid damage to the prestressed jacking pipe. An anti-skid layer is arranged on the buffer layer of the base and the load-bearing seat, and the anti-skid layer is a semicircular rubber protrusion. The outer wall of the prestressed jacking pipe is smooth and thick and is not easy to fix. The anti-skid layer can increase friction with the outer wall of the prestressed jacking pipe to prevent the prestressed jacking pipe from sliding during transportation.

[0004] However, the fixing device for transporting prestressed steel cylinder concrete jacking pipe in the above application can only transport steel cylinder concrete pipes of a specific diameter, and cannot well fix pipes of different diameters. Therefore, there are certain limitations.

[0005] For this reason, we urgently need to provide a kind of convenient fixing device for transporting steel cylinder concrete pipe. Utility Model Content

[0006] The purpose of the utility model is to provide a fixing device for convenient transportation of steel cylinder concrete pipes, so as to solve the problem that the fixing device for prestressed steel cylinder concrete jacking pipe transportation proposed in the above-mentioned background technology can only transport steel cylinder concrete pipes of a specific diameter and cannot fix pipes of different diameters well.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing device for convenient transportation of steel cylinder concrete pipes, comprising a base and a top seat, the top seat being installed on the upper surface of the base, the top of the base and the bottom of the top seat being respectively provided with semicircular through holes, a buffer device being arranged inside the base, and a fixing device being arranged inside the top seat.

[0008] The buffer device includes a rubber pad, a buffer sponge pad, and a buffer assembly. The rubber pad is arranged inside the base, the buffer sponge pad is adhered to the outside of the rubber pad, and the upper and lower ends of the buffer assembly are respectively fixedly connected between the buffer sponge pad and the base. The setting of the rubber pad increases the friction between the pipeline and the rubber pad, and tries to avoid the rolling of the pipeline. The buffer sponge pad plays a certain buffering role.

[0009] A further improvement is that the buffer assembly includes a spring sleeve, sound-absorbing cotton, and a buffer spring. The upper and lower ends of the spring sleeve are respectively fixedly connected between the buffer sponge pad and the base. The sound-absorbing cotton is fixedly adhered to the inside of the spring sleeve. The buffer spring is installed inside the spring sleeve, and its upper and lower ends are also respectively fixedly connected between the buffer sponge pad and the base. The buffer spring is used to buffer the impact force received by the pipeline during transportation to prevent the pipeline from being broken due to impact.

[0010] A further improvement is that the buffer components are grouped into five and fixedly connected to the inner side of the through hole on the base in a ring shape, and several groups of buffer components are longitudinally equidistantly arranged on the inner side of the through hole, and multiple groups of buffer components cooperate with each other to better protect the pipeline.

[0011] A further improvement is that the fixing device includes a telescopic rod, a sliding sleeve, a telescopic spring, a sliding rod, and an arc-shaped fixing plate, the telescopic rod is arranged inside the top of the top seat, the sliding sleeve is fixedly connected to the bottom of the telescopic rod, the telescopic spring is installed inside the sliding sleeve, the top of the sliding rod is fixedly connected to the bottom of the telescopic spring and is slidably connected to the inside of the sliding sleeve, the arc-shaped fixing plate is fixedly connected to the bottom of the sliding rod, a rubber layer is adhered to the inner side of the arc-shaped fixing plate, and pipes of different diameters are clamped and fixed inside the through hole on the base through the arc-shaped fixing plate.

[0012] A further improvement is that a telescopic hole is provided at the upper end of the top interior of the top seat, and a sliding sleeve hole is provided at the lower end, and the telescopic hole is communicated with the sliding sleeve hole, and the telescopic rod and the sliding sleeve are slidably connected to the inside of the telescopic hole and the sliding sleeve hole respectively. When the pipeline is installed and transported, the top of the top seat will continue to be stacked and installed, and another group of bases on its top will be pressed down, thereby forcing the telescopic rod to move downward, thereby driving the sliding sleeve to move downward, so that the arc-shaped fixing plate abuts against the surface of the pipeline, thereby squeezing the telescopic spring, avoiding hard contact, and fracturing the pipeline, so as to better fix pipelines of different diameters inside the through hole, making it more convenient to carry out transportation work.

[0013] A further improvement is that there are three groups of fixing devices, which are longitudinally equidistantly arranged inside the top seat, and the three groups of fixing devices cooperate with each other to better fix the pipe inside the through holes inside the base and the top seat.

[0014] A further improvement is that four plug-in grooves are respectively provided on the left and right sides of the upper surface and the right outer surface of the base and the right outer surface of the top seat, and plug-in blocks are correspondingly fixedly connected to the left and right sides of the lower surface and the left outer surface of the top seat and the left outer surface of the base.

The buffer spring 3033 is installed inside the spring sleeve 3031, and its upper and lower ends are also respectively fixedly connected between the buffer sponge pad 302 and the base 1. The buffer spring 3033 is used to buffer the impact force received by the pipeline during transportation to prevent the pipeline from being broken due to impact.

[0029] Each group of five buffer components 303 is annularly fixedly connected to the inner side of the through hole on the base 1, and several groups of buffer components 303 are longitudinally equidistantly arranged on the inner side of the through hole. Multiple groups of buffer components 303 cooperate with each other to better protect the pipeline.

During transportation, the setting of the rubber pad 301 increases the friction between the pipe and the rubber pad 301, and tries to avoid the pipe rolling. The buffer sponge pad 302 plays a certain buffering role. At the same time, the impact force received by the pipe during transportation is buffered by the buffer spring 3033, so as to avoid the pipe being broken due to impact.

[0032] Embodiment 2:

[0033] On the basis of Example 1, a fixing device is provided inside the top seat 2, and the fixing device includes a telescopic rod 401, a sliding sleeve 402, a telescopic spring 403, a slide rod 404, and an arc-shaped fixing plate 405.
