Description

Technical Field

[0001] This invention relates to the field of pressure steel pipe assembly technology. More specifically, this invention relates to a pressure steel pipe assembly device. Background Technology

[0002] Pressure steel pipes are often used in some water conservancy projects. The diameter of pressure steel pipes in water conservancy projects can reach 2m to 3m. During the construction of these pressure steel pipes, steel plates are first rolled and then the two ends of the steel plates are welded to form a complete circle. After rolling, the rolled steel plates cannot maintain the predetermined rolling state, which causes the two ends of the steel plates to be misaligned during welding. External force is required to push the two ends of the steel plates to align them before welding. The existing pressure steel pipe assembly device has the following defects: firstly, the power to push the pressure steel pipe is insufficient; secondly, it cannot be used to assemble pressure steel pipes of different diameters; and thirdly, it cannot simultaneously perform the function of adjusting the circle. After the circle is assembled, a circle adjustment frame is still needed for radial adjustment, and lifting is also required, which greatly affects the production efficiency of pressure steel pipes. The invention patent with publication number CN116275848A, entitled "A Horizontal Automatic Circulation Device for Large Pressure Steel Pipes," discloses a horizontal automatic circulation device comprising a fixed frame, a movable frame, and two symmetrically arranged tilting frames on the movable and fixed frames. Both tilting frames are semi-circular steel trusses, with the negative side of the semi-circular truss serving as the bearing surface for the steel pipe tiles. Six sets of steel plate clamping mechanisms for fixing the steel pipe tiles are equally spaced on each side of the semi-circular truss. The power source for pushing the pressure steel pipes is the power generated by the tilting of the two tilting frames. Sometimes, this power is insufficient to align the steel pipe tiles. The diameter of the semi-circular tilting frame is fixed, making it unsuitable for circulation operations of pressure steel pipes with different diameters. After the tilting frame is tilted, it does not have a circular adjustment function, requiring the pressure steel pipe to be lifted for the next circular adjustment process. Summary of the Invention

[0003] One object of the present invention is to solve at least the above-mentioned problems and to provide at least the advantages that will be described later.

[0004] Another objective of this invention is to provide a pressure steel pipe assembly device that combines the assembly and adjustment processes, thereby greatly improving the efficiency of pressure steel pipe manufacturing.

[0005] To achieve these objectives and other advantages according to the present invention, a pressure steel pipe assembly device is provided, comprising:

[0006] The assembly includes a base and an assembly sleeve mounted on the base. A circular array of radial slide rails is arranged on the inner wall near one end of the assembly sleeve. A radial support rod is slidably mounted within each radial slide rail. One end of the radial support rod extending out of the assembly sleeve is equipped with a pressure steel pipe tile holder, and the other end is equipped with a displacement sensor. Radial telescopic rods, spaced apart from the radial slide rails, are arranged on the inner wall of the assembly sleeve. Multiple rows of these radial telescopic rods are arranged axially. Each radial telescopic rod has a first jack at its top, and a displacement sensor and a pressure sensor are located at the top of the first jack.

[0007] The adjusting section, located on the side of the assembled circular sleeve near the radial slide rail, includes a vertical support arranged radially along the assembled circular sleeve, a telescopic crossbar hinged to the top of the vertical support and extending towards the center of the assembled circular sleeve, and telescopic pressure rods arranged in a circular array on the top of the telescopic crossbar. The top of the vertical support is at the same height as the center of the assembled circular sleeve. The distribution of the telescopic pressure rods corresponds one-to-one with the radial telescopic rods distributed in the circumferential direction. A second jack is provided at the top of each telescopic pressure rod, and a displacement sensor and a pressure sensor are provided at the top of the second jack.

[0008] Preferably, the pressure steel pipe assembly device further includes an I-beam lifting device located on the other side of the assembly sleeve.

[0009] Preferably, the radial support rod is driven by a hydraulic rod, and a slider is provided at the bottom of the end of the radial support rod near the radial slide rail.

[0010] Preferably, the pressure steel pipe tile holder includes a support plate disposed at the end of a radial support rod, and the support plate has slots.

[0011] Preferably, the width of the slot is slightly larger than the thickness of the pressure steel pipe tile.

[0012] Preferably, the length of the slot is 1 / 2 to 2 / 3 of the length of the circular sleeve.

[0013] The present invention further claims a method of using the pressure steel pipe assembly device, including:

[0014] Step 1: Adjust the radial support rod and radial telescopic rod so that the diameter of the circle they form is larger than the diameter of the pressure steel pipe to be assembled. Hoist the pressure steel pipe tile to be assembled and insert it into the pressure steel pipe tile holder. Gradually extend the radial support rod and radial telescopic rod outward until they contact the end of the pressure steel pipe tile.

[0015] Step 2: Weld the ends of the pressure steel pipe tiles, gradually extending the first row of radial telescopic rods outwards until the diameter of the circle formed after the step is exactly equal to the diameter of the pressure steel pipe to be assembled and the sum of the thicknesses of the two pressure steel pipes to be assembled. Adjust the telescopic crossbar so that the telescopic pressure rod is directly opposite the first row of radial telescopic rods. If the pressure sensor at the end of any radial telescopic rod senses a pressure greater than 0, slowly extend the corresponding telescopic pressure rod until the pressure sensor at the end of that radial telescopic rod senses a pressure of 0. Then adjust the distance of the telescopic pressure rods so that their length is exactly equal to the radius of the pressure steel pipe to be assembled. If the pressure sensor at the end of any telescopic pressure rod senses a pressure greater than 0, slowly extend the corresponding radial telescopic rod until the pressure sensor at the end of that telescopic pressure rod senses a pressure of 0. Repeat the above steps to check the circumference of the position of each row of radial telescopic rods.

[0016] The present invention has at least the following beneficial effects: The pressure steel pipe alignment device provided by the present invention includes an alignment section and an adjustment section, wherein the alignment section and the adjustment section share multiple rows of radial telescopic rods. During the alignment operation, the multiple rows of radial telescopic rods provide power for the alignment of the pressure steel pipe. The thrust provided by the multiple rows of radial telescopic rods has high stability and good axial dynamic balance, which greatly reduces the difficulty of the adjustment operation. During the adjustment operation, the multiple rows of radial telescopic rods, together with the retractable pressure rods that extend and retract, check the radius of each part of the pressure steel pipe and complete the adjustment operation. The pressure steel pipe alignment device provided by the present invention occupies a small area and only requires one set of lifting equipment to complete the two processes of alignment and adjustment of the pressure steel pipe.

[0017] Other advantages, objectives and features of the present invention will become apparent in part from the following description, and in part from those skilled in the art through study and practice of the invention. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0022] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not imply the presence or addition of one or more other elements or combinations thereof.

[0023] like Figures 1-3 As shown, the present invention provides a pressure steel pipe assembly device, comprising:

[0024] The assembly includes a base 1 and an assembly sleeve 2 mounted on the base 1. A circular array of radial slide rails 3 is arranged on the inner wall near one end of the assembly sleeve 2. A radial support rod 5 is slidably mounted within each radial slide rail 3. One end of the radial support rod 5 extending out of the assembly sleeve 2 is equipped with a pressure steel pipe tile holder 7, and the other end is equipped with a displacement sensor. Radial telescopic rods 6 are arranged on the inner wall of the assembly sleeve 2 at intervals from the radial slide rails 3. Multiple rows of the circular array of radial telescopic rods 6 are distributed axially. A first jack 8 is mounted at the top of each radial telescopic rod 6, and a displacement sensor and a pressure sensor are mounted at the top of the first jack 8.

[0025] The adjusting section, located on the side of the circular sleeve 2 near the radial slide rail 3, includes a vertical support 9 arranged radially along the circular sleeve, a telescopic crossbar hinged to the top of the vertical support 9 and extending towards the center of the circular sleeve, and telescopic pressure rods 4 arranged in a ring array on the top of the telescopic crossbar. The top of the vertical support 9 is at the same height as the center of the circular sleeve. The distribution of the telescopic pressure rods 4 corresponds one-to-one with the radial telescopic rods 6 distributed in the circumferential direction. A second jack is provided on the top of the telescopic pressure rod 4, and a displacement sensor and a pressure sensor are provided on the top of the second jack.

[0026] In the above technical solution, the pressure steel pipe assembly includes a circular assembly section and an adjusting section, arranged sequentially rearward. The circular assembly section is located in front of the adjusting section. The circular assembly section includes a circular assembly sleeve 2 and radial support rods 5 and radial telescopic rods 6 disposed on the inner wall of the circular assembly sleeve 2. The length of the circular assembly sleeve 2 should be greater than the length of a typical pressure steel pipe. The radial support rods 5 and radial telescopic rods 6 are arranged in a spaced-apart annular array. The radial support rods 5 slide in the radial slide rail 3, allowing the diameter of the circle formed by the radial support rods 5 to be variable, which can be used for circular assembly and adjusting of pressure steel pipes of different diameters. In the process, the top of the radial support rod 5 is equipped with a pressure steel pipe tile clamping component to hold the pressure steel pipe tile. The cooperation of the radial support rod 5 and the radial telescopic rod 6 provides the power for aligning the pressure steel pipe. From the force perspective, the pressure steel pipe is divided into multiple force-bearing layers, each layer having multiple force-bearing points. The end of the radial telescopic rod 6 is also equipped with a displacement sensor and a pressure sensor to monitor the displacement of each force-bearing point and the pressure value on the pressure steel pipe, providing a multi-directional and balanced power source for the alignment of the pressure steel pipe, greatly reducing the workload of rounding. The rounding part is located on the outside of the rounding sleeve 2, such as... Figure 3As shown, its vertical support can be directly installed, or it can be more stably installed by setting a counterweight 11 at the bottom. The telescopic crossbar 10 of the adjustment part allows the telescopic pressure rod 4 of the adjustment part to be adjusted to face any row of telescopic rods 6. With the cooperation of the radial telescopic rods 6, the telescopic pressure rod 4 of the adjustment part completes the inspection and adjustment of the radius of multiple stress points of the pressure steel pipe. The working principle of the telescopic pressure rod 4 and the radial telescopic rod 6 is as follows: a certain telescopic length is set (determined by calculating the radius and wall thickness of the pressure steel pipe). If the pressure value detected at the end of the radial telescopic rod 6 is greater than 0, the displacement of the telescopic pressure rod 4 is gradually increased until the pressure value detected at the end of the radial telescopic rod 6 is 0. All sensors in the attached figure are not shown.

[0027] In the above technical solution, the method of using the pressure steel pipe assembly device is as follows:

[0028] Step 1: Adjust the radial support rod 5 and the radial telescopic rod 6 so that the diameter of the circle they form is larger than the diameter of the pressure steel pipe to be assembled. Hoist the pressure steel pipe tile to be assembled and insert it into the pressure steel pipe tile holder. Gradually extend the radial support rod 5 and the radial telescopic rod 6 outward until they contact the end of the pressure steel pipe tile.

[0029] Step 2: Weld the ends of the pressure steel pipe tiles, gradually extending the first row of radial telescopic rods 6 outwards until the diameter of the circle formed after the step is exactly equal to the diameter of the pressure steel pipe to be assembled and the sum of the thicknesses of the two pressure steel pipes to be assembled. Adjust the telescopic crossbar so that the telescopic pressure rod 4 is directly opposite the first row of radial telescopic rods. If the pressure sensor at the end of any radial telescopic rod senses a pressure greater than 0, slowly extend the corresponding telescopic pressure rod until the pressure sensor at the end of that radial telescopic rod senses a pressure of 0. Then adjust the distance of the telescopic pressure rods so that their length is exactly equal to the radius of the pressure steel pipe to be assembled. If the pressure sensor at the end of any telescopic pressure rod senses a pressure greater than 0, slowly extend the corresponding radial telescopic rod until the pressure sensor at the end of that telescopic pressure rod senses a pressure of 0. Repeat the above steps to check the circumference of the position of each row of radial telescopic rods.

[0030] In one of the technical solutions, the pressure steel pipe rounding device also includes an I-beam lifting device on the other side of the rounding sleeve, which is used to lift the rolled pressure steel pipe into the pressure steel pipe rounding device to complete the rounding and adjustment operations.

[0031] like Figures 1-3In one of the technical solutions, the radial support rod 5 is driven by a hydraulic rod, and a slider is provided at the bottom of the end of the radial support rod 5 near the radial slide rail 3. The radial support rod 5 is set in the radial slide rail 3, which has better stability than the radial telescopic rod 6, which is beneficial to maintaining the stability of the pressure steel pipe tile. The structure of the radial slide rail 3 and the slider is beneficial to reducing the friction between the radial support rod 5 and the radial slide rail 3.

[0032] exist Figures 1-3 As can be seen from the above, in one of the technical solutions, the pressure steel pipe tile holder includes a support plate disposed at the end of the radial support rod 5. The support plate has a slot, and the length of the support plate along the axial direction of the circular sleeve is not less than 1 / 2 of the axial length of the circular sleeve 2. The opening of the slot extends in a direction away from the adjusting part, and is used to fix the pressure steel pipe tile into the circular sleeve 2.

[0033] In one of the technical solutions, the width of the slot is slightly larger than the thickness of the pressure steel pipe tile, making it easier to fix the pressure steel pipe tile inside the round sleeve.

[0034] In one of the technical solutions, the length of the slot is 1 / 2 to 2 / 3 of the length of the assembly sleeve, so that most of the pressure steel pipe tile is fixed in the slot, ensuring the stability of the assembly and adjustment operations.

[0035] The present invention further claims a method of using the pressure steel pipe assembly device, including:

[0036] Step 1: Adjust the radial support rod 5 and the radial telescopic rod 6 so that the diameter of the circle they form is larger than the diameter of the pressure steel pipe to be assembled. Hoist the pressure steel pipe tile to be assembled and insert it into the pressure steel pipe tile holder. Gradually extend the radial support rod 5 and the radial telescopic rod 6 outward until they contact the end of the pressure steel pipe tile.

[0037] Step 2: Weld the ends of the pressure steel pipe tiles, gradually extending the first row of radial telescopic rods 6 outwards until the diameter of the circle formed after the step is exactly equal to the diameter of the pressure steel pipe to be assembled and the sum of the thicknesses of the two pressure steel pipes to be assembled. Adjust the telescopic crossbar 10 so that the telescopic pressure rod 4 is directly opposite the first row of radial telescopic rods 6. If the pressure sensor at the end of any radial telescopic rod 6 senses a pressure greater than 0, slowly extend the telescopic pressure rod 4 corresponding to that radial telescopic rod 6 until the pressure sensor at the end of that radial telescopic rod 6 senses a pressure of 0. Then adjust the distance of the telescopic pressure rods so that their length is exactly equal to the radius of the pressure steel pipe to be assembled. If the pressure sensor at the end of any telescopic pressure rod 4 senses a pressure greater than 0, slowly extend the radial telescopic rod corresponding to that telescopic pressure rod 4 until the pressure sensor at the end of that telescopic pressure rod 4 senses a pressure of 0. Repeat the above steps to check the circumference of the position of each row of radial telescopic rods 6.

[0038] In the above technical solution, the initial extension length of the radial support rod 5 and the radial telescopic rod 6 in step one can be more accurately determined according to the actual diameter of the rolled pressure steel pipe tile. The radial support rod 5 and the radial telescopic rod 6 are adjusted so that the diameter of the circle they form is larger than the actual diameter of the rolled pressure steel pipe tile. In step one, the adjustment of the radial support rod 5 and the radial telescopic rod 6 is carried out simultaneously. In step two, the radial telescopic rods 6 in the same row are both operated synchronously and individually. The telescopic pressure rod 4 is also operated synchronously and individually. The combination of the telescopic rod 6 and the telescopic pressure rod 4 allows for fine-tuning the radius of the pressure steel pipe. The working principle of the telescopic pressure rod 4 and the radial telescopic rod 6 for rounding is as follows: A certain telescopic length is set (determined by calculating the radius and wall thickness of the pressure steel pipe). If the pressure value detected at the end of the radial telescopic rod 6 is greater than 0, the displacement of the telescopic pressure rod 4 is gradually increased until the pressure value detected at the end of the radial telescopic rod 6 is 0. Step two also includes a review step for the rounding operation of the pressure steel pipe. Specifically, each row of radial telescopic rods 6 is adjusted until the diameter of the circle formed after its stepping is exactly equal to the diameter of the pressure steel pipe to be assembled and the sum of the thicknesses of the two pressure steel pipes to be assembled. The distance between the telescopic pressure rods 4 is adjusted so that its length is exactly equal to the radius of the pressure steel pipe to be assembled. The pressure sensors at the ends of the corresponding radial telescopic rods 6 and telescopic pressure rods 4 are confirmed to have a pressure of 0.

During the alignment operation, the multiple rows of radial telescopic rods provide power for the alignment of the pressure steel pipe.
