Description

Technical Field

[0001] The utility model relates to the technical field of pipeline installation, in particular to an auxiliary device for assembling storage tanks and pipelines. Background Art

[0002] As an efficient, safe and economical logistics method, pipeline transportation is widely used in the fields of industry, petrochemicals, construction, etc. Pipeline technology and piping technology are also constantly being improved and optimized. In the construction of pipeline transportation lines, pipeline technology and piping technology play a vital role and directly affect production efficiency and product quality. Among them, the assembly of storage tanks and pipelines, and the assembly of pipelines and pipelines are particularly important. Various auxiliary devices are required for auxiliary construction during assembly. When assembling existing storage tanks and pipelines, a lift is often used to lift the pipeline to be assembled, align the flanges on the pipelines, move one side of the pipeline, and align the flanges on the pipelines at both ends. The flanges are fitted and then fixed with bolts to assemble the pipeline. The traditional auxiliary device for assembling storage tanks and pipelines only uses a lift to assist in the lifting work. When docking the pipelines, the pipelines are often manually aligned with each other, and then the pipelines are moved to fit the flanges on the pipelines. When docking, due to the low accuracy of manual alignment, the center positions of the flanges on the two pipelines will be offset and misaligned, affecting the installation effect between the two pipelines, and even causing insufficient sealing when the pipeline is used subsequently. For this reason, we propose an auxiliary device for assembling storage tanks and pipelines. Utility Model Content

The mounting frame on the left is fixedly connected to the left upper end of the base, and the mounting frame on the right is slidably connected to the right upper end of the base. The slide grooves are opened in the middle of the upper end of the mounting frame, and the sliders are slidably connected to the inside of the slide groove. The upper end of the slider is provided with evenly distributed bolt holes. There is a top block slidably connected between the two sliders located in the same mounting frame, so that the running distance of the slider can be kept consistent, and pipes of different diameters can be quickly clamped, so that the center of the pipes on both sides are always on the same axis, and they are automatically aligned and fitted, which reduces manual intervention and improves assembly accuracy.

[0007] Furthermore, the clamping mechanism also includes clamping plates, which are mounted on the upper end of the slider by bolts to facilitate clamping of pipes with different diameters.

The groove is opened in the middle of the upper end of the base, the screw rod is rotatably connected to the inside of the groove, the limit block is slidably connected to the inside of the groove, the upper end of the limit block is fixedly connected to the middle of the bottom end of the mounting frame on the right side, and the outer surface of the screw rod is connected to the internal thread of the limit block, so that alignment and fitting work can be quickly performed.

[0010] Furthermore, it also includes a motor, which is arranged on the right side of the inside of the base, the input end of the motor is electrically connected to the output end of the single-chip microcomputer, and the right end of the output shaft of the motor is fixedly connected to the left end of the screw rod to provide stable drive for the alignment and fitting work.

[0011] Furthermore, it also includes a stabilizing groove, which is respectively arranged on the front and rear inner walls of the base, and the outer surface of the stabilizing groove is installed in cooperation with the lower ends of the front and rear sides of the mounting frame, so that the movement of the mounting frame on the right side is more stable.

[0012] Furthermore, it also includes a single-chip microcomputer, which is fixedly connected to the middle of the front end of the base, and the input end of the single-chip microcomputer is electrically connected to an external power supply to provide a control effect for the assembly work.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the auxiliary device for assembling storage tanks and pipelines has the following advantages:

[0014] 1. Place the pipe to be assembled on the upper end of the right mounting frame. The single-chip microcomputer controls the electric push rod on the right to work. The telescopic end of the electric push rod slowly retracts downward, and the top block slowly moves downward. The slider will slowly move inward along the slide groove as the top block moves downward, and the clamping plate will also move inward at the same time until the relative inner side of the clamping plate is close to the outer surface of the right pipe. At this time, the pipe to be assembled on the right is fixed, and then the pedal of the elevator is continuously stepped on. The elevator rises with the base, and the pipe moves up with it until the outer surface of the left pipe contacts the upper end of the left mounting frame. At this time, the The horizontal heights of the pipelines are consistent, and the single-chip microcomputer controls the operation of the electric push rod on the left. The telescopic end of the electric push rod is slowly retracted downward, and the top block is slowly moved downward. The slider slowly moves inward along the slide groove as the top block moves downward, and the clamping plate also moves inward at the same time, until the relative inner side of the clamping plate is close to the outer surface of the left pipeline. At this time, the center of the pipelines on both sides are aligned and the axis lines coincide. During the assembly process of storage tanks and pipelines, for pipelines with diameters that are too large or too small, you only need to install the clamping plate on different bolt holes through bolts according to the diameter of the pipeline to adapt to the clamping work of pipelines of different diameters.

[0015] 2. The single-chip microcomputer controls the operation of the motor, and the output shaft of the motor drives the screw to rotate. Because the upper end of the limit block is fixedly connected to the middle of the bottom end of the mounting bracket on the right, and the outer surface of the screw is connected to the internal thread of the limit block, the mounting bracket on the right will move to the left as the screw rotates. The stabilizing groove can make the movement of the mounting bracket smoother until the flange on the right pipe is close to the flange on the left pipe. At this time, you only need to fix the two flanges with bolts to complete the assembly of the pipeline. During the assembly process of storage tanks and pipelines, automatic alignment and fitting are achieved, which reduces manual intervention and improves assembly accuracy.

[0023] The clamping mechanism 7 includes a mounting frame 71, a slide groove 72, a slider 73 and a top block 74. The mounting frame 71 on the left is fixedly connected to the left side of the upper end of the base 1, and the mounting frame 71 on the right is slidably connected to the right side of the upper end of the base 1. The slide grooves 72 are all opened in the middle of the upper end of the mounting frame 71. The sliders 73 are slidably connected to the inside of the slide grooves 72. The upper ends of the sliders 73 are provided with uniformly distributed bolt holes. A top block 74 is slidably connected between the two sliders 73 located in the same mounting frame 71, so that the running distance of the sliders 73 can be kept consistent. The clamping mechanism 7 also includes a clamping plate 75. The clamping plate 75 is installed on the upper end of the slider 73 by bolts. The relative inner sides of the clamping plate 75 are provided with uniformly distributed anti-slip protrusions. In order to facilitate clamping of pipes of different diameters, the clamping mechanism 7 also includes an electric push rod 76, which is arranged in the middle of the mounting frame 71.

[0024] The working principle of the auxiliary device for assembling storage tanks and pipelines provided by the utility model is as follows: during the assembly process of storage tanks and pipelines, the equipment is first pushed to the construction area, the self-locking wheels are fixed, and the pipeline to be assembled is placed on the upper end of the right mounting frame 71. The single-chip microcomputer 9 controls the electric push rod 76 on the right to work, and the telescopic end of the electric push rod 76 is slowly retracted downward, and the top block 74 is slowly moved downward. Since there is a top block 74 slidably connected between the two sliders 73 located inside the same mounting frame 71, the slider 73 will slowly move along the top block 74 as the top block 74 moves downward. As the slide groove 72 moves inward, the clamping plate 75 also moves inward at the same time until the inner side surface of the clamping plate 75 is in close contact with the outer surface of the right pipe. At this time, the pipe to be assembled on the right side is fixed, the external hydraulic pump station works, the lifter 2 brings the base 1 up, and the pipe moves up accordingly until the outer surface of the left pipe contacts the upper end of the left mounting bracket 71. At this time, the horizontal heights of the pipes on both sides are consistent, the single chip computer 9 controls the electric push rod 76 on the left to work, the telescopic end of the electric push rod 76 is slowly retracted downward, and the top block 74 is slowly moved downward, and the slider As the top block 74 moves downward, 73 slowly moves inward along the slide groove 72, and the clamping plate 75 also moves inward at the same time, until the inner side of the clamping plate 75 is close to the outer surface of the left pipe. At this time, the centers of the pipes on both sides are aligned, and the axes are also coincident. The single-chip microcomputer 9 controls the motor 6 to operate, and the output shaft of the motor 6 drives the screw rod 4 to rotate. Because the upper end of the limit block 5 is fixedly connected to the middle of the bottom end of the right mounting bracket 71, and the outer surface of the screw rod 4 is connected to the internal thread of the limit block 5, the mounting bracket 71 on the right will move to the left with the rotation of the screw rod 4, and the stability is achieved. The groove 8 can make the movement of the mounting frame 71 smoother until the flange on the right pipe is close to the flange on the left pipe. At this time, the two flanges only need to be fixed with bolts to complete the assembly of the pipes. For pipes with too large or too small diameters, the clamping plate 75 only needs to be installed on different bolt holes through bolts according to the diameter of the pipe. This can adapt to the clamping of pipes with different diameters. Pipes with different diameters can be clamped quickly so that the centers of the pipes on both sides are always on the same axis, automatically aligning and fitting, reducing manual intervention and improving assembly accuracy.
