Description

Technical Field

[0001] This utility model relates to the field of pipeline construction equipment technology, and in particular to an auxiliary device for the installation of prestressed steel cylinder concrete circulating water pipeline. Background Technology

[0002] In the field of circulating water pipeline system installation, prestressed concrete cylinder pipes (PCCP) are widely used in thermal power generation projects, municipal water supply, and industrial circulating water systems due to their excellent structural strength and durability. However, these pipes are typically heavy (a single section can weigh tens of tons), long (several meters in length), and rigid, leading to the following technical challenges during installation:

[0003] Limitations of traditional hoisting methods: Existing hoisting devices mostly rely on a single hoisting point or fixed lifting equipment, which can only complete the lifting and rough positioning of pipelines. It is difficult to make fine adjustments to the horizontal orientation (such as axial deflection) and tilt angle (such as slope adjustment) of pipelines while they are in the hoisting state. Repeated hoisting and calibration are required, which is inefficient. Furthermore, pipelines must meet strict axis alignment and slope requirements when they are connected. Traditional methods rely on manual pulling or adjustment with pads, which are easily limited by construction space. Fine adjustment of heavy pipelines is also difficult and can easily lead to installation deviations. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary device for the installation of prestressed steel cylinder concrete circulating water pipelines, so as to solve the technical problem of difficulty in adjusting the horizontal orientation and tilt angle encountered in the traditional circulating water pipeline installation process.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an auxiliary device for the installation of prestressed steel cylinder concrete circulating water pipelines, the auxiliary device comprising:

[0034] Please see Figures 1 to 3 This application provides an auxiliary device for installing prestressed steel cylinder concrete circulating water pipelines, including a hoisting platform 1, a rotation adjustment part 2, a slope adjustment part 3, and a lifting ring 4. The hoisting platform 1 is horizontally fixed to the wire rope 5 of a hoisting device (such as a crane); the rotation adjustment part 2 is disposed on the hoisting platform 1, and the direction of the rotation shaft 21 of the rotation adjustment part 2 is perpendicular to the horizontal plane. The rotation adjustment part 2 is used to adjust the pipe 6 (such as...) Figure 1 The horizontal orientation of the DN3800 (PCCP) pipe 90° bend is shown in the middle; the slope adjustment part 3 is on the rotation adjustment part 2, and the slope adjustment part 3 is used to adjust the inclination angle of the pipe 6; the lifting ring 4 is set on the slope adjustment part 3, and the lifting ring 4 is used to lift and fix the pipe 6.

[0035] The prestressed steel cylinder concrete circulating water pipe 6 installation auxiliary device provided by this utility model uses a lifting ring 4 to hoist and fix the pipe 6 during the hoisting and installation process. The horizontal orientation of the pipe 6 is adjusted by rotating the adjustment part 2, and the inclination angle of the pipe 6 is adjusted by the slope adjustment part 3. This allows the orientation and slope (inclination angle) of the hoisted pipe 6 to be adjusted according to the installation requirements, solving the problem that the orientation and slope adjustment of the prestressed steel cylinder concrete circulating water pipe 6 are inconvenient during the installation process due to its large weight and size.

[0036] The lifting ring 4 is existing technology, which is used to connect and fix the pipe 6 during the lifting of the pipe 6. This application does not improve the lifting ring 4, so the specific structure of the lifting ring 4 will not be described here.

[0037] In one embodiment, the rotation adjustment unit 2 includes a rotating shaft 21, a gear set 23, and a first rotation power unit 22. The rotating shaft 21 is rotatably disposed at the center of the hoisting platform 1, and the rotation axis of the rotating shaft 21 is perpendicular to the horizontal plane. The slope adjustment unit 3 is installed on the rotating shaft 21. The first rotation power unit 22 is disposed at the bottom of the hoisting platform 1. The gear set 23 is disposed on the power output shaft of the rotating shaft 21 and the first rotation power unit 22, and the first rotation power unit 22 drives the rotating shaft 21 to rotate.

[0038] When it is necessary to adjust the horizontal orientation of pipe 6, simply control the first rotational power unit 22 to rotate by a certain angle. The first rotational power unit 22 then drives the rotating shaft 21 to rotate by a certain angle via the gear set 23 (the ratio of the rotation angle of the first rotational power unit 22 to the rotation angle of the rotating shaft 21 is the same as the transmission ratio of the gear set 23). This causes the slope adjustment unit 3 mounted on the rotating shaft 21, as well as the hanging ring 4 and pipe 6 below it, to rotate synchronously with the rotating shaft 21 by the same angle (e.g., ...). Figure 2 As shown in the figure, this allows for adjustment of the horizontal orientation of pipe 6.

[0039] like Figure 4 As shown, in one embodiment, a bearing device 24 is provided between the rotating shaft 21 and the hoisting platform 1. By providing the bearing device 24 between the rotating shaft 21 and the hoisting platform 1, the frictional force between the rotating shaft 21 and the hoisting platform 1 when rotating is reduced, and the resistance encountered by the adjustment pipe 6 of the rotation adjustment part 2 when it is horizontal is reduced.

[0040] In one embodiment, the slope adjustment unit 3 includes a crossbar 31, a first winch 32, a second winch 33, a second rotational power unit 34, a third rotational power unit 35, and two cables 36. The crossbar 31 is fixed to the rotating shaft 21. The first winch 32 and the second winch 33 are symmetrically arranged on both sides of the crossbar 31. The second rotational power unit 34 and the third rotational power unit 35 are disposed on the crossbar 31 and are used to drive the first winch 32 and the second winch 33, respectively. One end of each cable 36 is wound around the first winch 32 and the second winch 33, respectively, and the other end of each cable 36 is individually connected to a lifting ring 4.

[0041] When it is necessary to adjust the inclination angle (slope) of pipe 6, simply activate the second rotating power unit 34 and the third rotating power unit 35, with the second rotating power unit 34 working in the forward direction and the third rotating power unit 35 working in the reverse direction. This causes the first winch 32 to tighten the cable 36 and the second winch 33 to loosen the cable 36, causing the left side of pipe 6 to rise and the right side to fall, thereby adjusting the inclination angle (slope) of pipe 6. Figure 2 The horizontal state on both sides is adjusted as follows Figure 3The pipe 6 is tilted with the left side higher than the right side, as shown. Therefore, by controlling the rotation angle / direction of the second rotation power unit 34 and the third rotation power unit 35, the amount of cable 36 wound up and unwound by the first winch 32 / second winch 33 can be precisely controlled, thereby precisely controlling the tilt angle (slope) of the pipe 6 to facilitate the installation of the pipe 6.

[0042] In one embodiment, the first rotational power unit 22, the second rotational power unit 34, and the third rotational power unit 35 are all servo motors. Because servo motors have closed-loop control characteristics, they can provide real-time feedback of speed and position signals, enabling the angle adjustment accuracy of the rotation adjustment unit 2 and the slope adjustment unit 3 to reach ±0.1°. This is particularly suitable for the stringent fine-tuning requirements of heavy PCCP pipes 6.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
