Technical Field

[0001] The present application relates to the field of pipeline installation, and in particular to a steel truss bridge pipe installation device and a method of using the same. Background Art

[0002] In municipal water supply pipeline projects, when the pipeline is designed to be installed on a steel truss, it is usually considered to install the main truss first, and then hoist the pipeline as a whole, so that the construction can be completed in one go. However, when the design crosses a suburban river and the terrain environment is relatively complex, the installation of steel trusses and large-diameter water supply pipelines becomes more difficult. The steel truss bridge must be hoisted as a whole to ensure the ease of truss construction. Therefore, the pipeline cannot be hoisted.

[0003] With respect to the above-mentioned related technologies, the inventors believe that the current installation method of large water supply pipeline bridge pipes on steel truss bridges is complicated, the construction is difficult, and the construction efficiency is low. Summary of the invention

DETAILED DESCRIPTION

[0053] The following is combined with Figure 1-6 This application is described in further detail.

[0054] An embodiment of the present application discloses a bridge tube installation device for a steel truss bridge.

[0055] Reference Figure 1 A steel truss bridge pipe installation device includes a steel truss 1, a mounting track mechanism 2 is installed on the steel truss 1, a pipe 3 is abutted on the mounting track mechanism 2, clamping mechanisms 5 are abutted at both ends of the pipe 3, the clamping mechanism 5 is installed on a sliding shell 4, and the sliding shell 4 is symmetrically slidably installed on both sides of the mounting track mechanism 2. A first pulley mechanism 6 is also installed on the sliding shell 4, a second pulley mechanism 7 is installed on the first pulley mechanism 6, and a third pulley mechanism 8 is installed at one end of the sliding shell 4 away from the first pulley mechanism 6.

[0056] When a steel truss bridge pipe installation device is working, the pipeline 3 is transported by the installation track mechanism 2 so that the pipeline 3 is installed in the steel truss 1. At the same time, the sliding shell 4 slides on both sides of the installation track mechanism 2 to control the position of the clamping mechanism 5, and adjusts the different positions of the pipeline 3 to ensure that the pipeline 3 will not shift during the installation process. At the same time, by setting the second pulley mechanism 7 and the third sliding mechanism, the sliding resistance of the sliding shell 4 on the installation track mechanism 2 is reduced, the difficulty of installing the pipeline 3 is reduced, and the construction efficiency is improved.

[0057] Reference Figure 1 and Figure 2 The mounting track mechanism 2 includes two symmetrically arranged I-beams 21, which are installed on the inner wall of the steel truss 1. The two I-beams 21 are fixedly connected by a number of evenly arranged stud bolts 22 threadedly connected to the steel groove. Nuts 23 are threadedly connected to both ends of the stud bolts 22. A bearing 24 is sleeved on the circumference of the stud bolt 22. The bearing 24 is a linear optical axis. The axial length of the bearing 24 is less than the distance between the steel grooves of the two I-beams 21, and the bearing 24 is abutted against a pipe 3.

[0058] When the track mechanism 2 is installed, the pipe 3 abuts against the bearing 24, and the construction personnel push the end of the pipe 3 away from the steel truss 1 to move toward the end close to the steel truss 1. During the movement of the pipe 3, the bearing 24 rotates in the axial direction of the stud bolt 22, reducing the resistance encountered by the pipe 3 when entering the steel truss 1 and reducing the difficulty of the construction operation.

[0059] Reference Figure 3 and Figure 4The clamping mechanism 5 includes two symmetrically arranged second support plates 514, a sleeve rod 513 is fixedly installed between the two second support plates 514, and two symmetrically arranged second springs 515 are sleeved on the circumferential side of the sleeve rod 513. The ends of the two second springs 515 away from each other are respectively abutted on the sides of the two second support plates 514 close to each other, and the ends of the two second springs 515 close to each other are abutted on the third connecting rod 512. The end of the third connecting rod 512 away from the sleeve rod 513 is fixedly connected to the limiting sleeve 510. The limiting sleeve 510 is symmetrically slidably sleeved with two limiting rods 59 in the axial direction, and the ends of the two limiting rods 59 close to each other are connected to the first spring 511. A first connecting rod 53 is provided at one end of the limiting rod 59 away from the bearing 24 of the two limiting rods 59, and a plurality of evenly arranged limiting holes 58 are opened on the first connecting rod 53. One end of the limiting rod 59 away from the bearing 24 is slidably sleeved in one of the plurality of limiting holes 58, and one end of the first connecting rod 53 away from the pipeline 3 is slidably sleeved in the shock absorbing shell 521 of the first shock absorbing assembly 52. ​​A shock absorbing spring 522 is also installed in the shock absorbing shell 521 of the first shock absorbing assembly 52, and the shock absorbing spring 522 of the first shock absorbing assembly 52 abuts against the first connecting rod 53. The shock absorbing shell 521 of the first shock absorbing assembly 52 is fixedly installed on the first support plate 51, and one end of the first support plate 51 away from the shock absorbing shell 521 of the first shock absorbing assembly 52 is fixedly installed on the sliding shell 4. The second connecting rod 55 is provided at one end of the limiting rod 59 close to the bearing 24 of the two limiting rods 59. The second connecting rod 55 is provided with a plurality of uniformly arranged limiting holes 58. The limiting rod 59 close to the bearing 24 is slidably sleeved in one of the plurality of limiting holes 58. The end of the second connecting rod 55 away from the pipe 3 is slidably sleeved in the damping housing 521 of the second damping assembly 54. A damping spring 522 is also installed in the damping housing 521 of the second damping assembly 54. The damping spring 522 of the second damping assembly 54 abuts against the second connecting rod 55. The damping housing 521 of the second damping assembly 54 is fixedly installed on the sliding housing 4. The ends of the first connecting rod 53 and the second connecting rod 55 away from the damping housing 521 are fixedly installed with abutting plates 56. The cross-sectional shape of the abutting plates 56 is trapezoidal. A damping roller 57 is installed on the side of the abutting plates 56 close to the pipe 3.

[0060] When the clamping mechanism 5 is working, firstly, the limiting hole 58 in which the limiting rod 59 is slidably sleeved is adjusted, and then the distance between the two symmetrically arranged clamping mechanisms 5 is adjusted, so that the clamping mechanism 5 can adapt to pipes 3 of different diameters. When the pipe 3 moves on the mounting track mechanism 2, under the thrust of the shock-absorbing spring 522, the damping roller 57 always abuts against the outer wall of the pipe 3, ensuring that the pipe 3 is in the center position of the mounting track mechanism 2, thereby avoiding the pipe 3 from being offset during the installation process, thereby causing damage to the outer wall of the pipe 3.

[0061] Reference Figure 3 and Figure 5 The first pulley mechanism 6 includes a first roller 61, which is arranged in a steel groove on the side of the I-beam 21 away from the stud bolt 22. A first rotating shaft 62 is fixedly sleeved on the side of the first roller 61 away from the stud bolt 22. One end of the first rotating shaft 62 away from the first roller 61 is rotatably connected to the sliding housing 4. A shift rod 66 is fixedly connected to the end of the first rotating shaft 62 close to the sliding housing 4. A stopper 65 is abutted against the end of the shift rod 66 away from the first rotating shaft 62. A fixing plate 63 is rotatably sleeved on the first rotating shaft 62. The fixing plate 63 is fixedly installed on the sliding housing 4. A spiral groove 64 is provided on the side of the fixing plate 63 away from the first roller 61. A stopper 65 is slidably connected in the spiral groove 64.

[0062] When the pipeline 3 is being installed, when the pipeline 3 moves in the direction of entering the steel truss 1, the sliding shell 4 is driven to slide on the I-beam 21 under the action of the clamping mechanism 5, and at the same time, the first roller 61 rolls on the I-beam 21. While the first roller 61 rolls, it drives the first rotating shaft 62 to rotate. The rotation of the first rotating shaft 62 drives the shift rod 66 to rotate around the axis of the first rotating shaft 62. The rotation of the shift rod 66 drives the stopper 65 to slide in the spiral groove 64. As the first rotating shaft 62 drives the shift rod 66 to rotate, it drives the stopper 65 to slide in the spiral groove 64 from the center position to the direction away from the center position until the stopper 65 slides to the end of the spiral groove 64 and the stopper 65 stops sliding. When the stopper 65 stops sliding, the stopper 65 abuts against the lever 66, causing the lever 66 to stop rotating, thereby causing the first rotating shaft 62 to stop rotating. When the first rotating shaft 62 stops rotating, the first roller 61 stops rotating, causing the first pulley mechanism 6 to stop sliding on the I-beam 21, thereby causing the sliding housing 4 to stop sliding on the I-beam 21. When the pipeline 3 enters the steel truss 1, the sliding housing 4 and the various mechanisms provided on the sliding housing 4 enter the steel truss 1 together with the pipeline 3. Then, under the action of the first pulley mechanism 6, the sliding housing 4 stops sliding when it slides to the middle section of the I-beam 21, so that the clamping mechanism 5 can adjust the position of the middle section of the pipeline 3.

[0063] Reference Figure 3 and Figure 4 The second pulley mechanism 7 includes an active bevel gear 71, which is fixedly sleeved on the first rotating shaft 62, and a driven bevel gear 72 is meshedly connected to the active bevel gear 71, and a second rotating shaft 73 is fixedly sleeved on the driven bevel gear 72. The second rotating shaft 73 is rotatably sleeved on a third supporting plate 74, and one end of the third supporting plate 74 away from the second rotating shaft 73 is fixedly installed on the sliding housing 4, and one end of the second rotating shaft 73 away from the driven bevel gear 72 is fixedly sleeved with a second roller 75, and the second roller 75 abuts against the I-beam 21.

[0064] When the first roller 61 rotates on the I-beam 21, the first roller 61 drives the first rotating shaft 62 to rotate, the first rotating shaft 62 drives the active bevel gear 71 to rotate, the first active bevel gear 71 drives the driven bevel gear 72 to rotate, the driven bevel gear 72 drives the second roller 75 to rotate through the second rotating shaft 73, so as to facilitate the sliding of the sliding housing 4 on the I-beam 21 and reduce the resistance of the sliding housing 4 when sliding.

[0065] Reference Figure 4 and Figure 6 The third pulley mechanism 8 includes two support rails 81 symmetrically fixedly mounted on the sliding housing 4. A slide groove 82 is provided on the side of the two support rails 81 close to each other. A third rotating shaft 83 is slidably connected in the two slide grooves 82. A third roller 84 is slidably sleeved on the third rotating shaft 83. The third roller 84 abuts against the I-beam 21. A third spring 85 is installed in each of the two slide grooves 82. One end of the third spring 85 is fixedly connected to the inner wall of the slide groove 82. One end of the third spring 85 away from the inner wall of the slide groove 82 abuts against the third rotating shaft 83.

[0066] When the third pulley mechanism 8 is working, the third roller 84 is always in contact with the I-beam 21 under the push of the third spring 85, reducing the resistance between the I-beam 21 and the sliding housing 4. When the sliding housing 4 moves on the I-beam 21, it drives the third roller 84 to rotate.

[0067] The implementation principle of one embodiment of the present application is as follows: when a steel truss bridge pipe installation device is working, the pipeline 3 is transported by installing a track mechanism 2, so that the pipeline 3 is installed in the steel truss 1, thereby reducing the difficulty of installing the pipeline 3 and improving the construction efficiency. At the same time, by setting a first pulley mechanism 6, the first pulley mechanism 6 drives the clamping mechanism 5 to move, so that the clamping mechanism 5 adjusts the different positions of the pipeline 3 to ensure that the pipeline 3 will not be offset during the installation process. A second pulley mechanism 7 and a third sliding mechanism are set to reduce the resistance of the sliding shell 4 to sliding on the installation track mechanism 2.

[0068] The embodiment of the present application also discloses a method for using a steel truss bridge pipe installation device.

[0069] Reference Figure 1 and Figure 3 A method for using a steel truss bridge pipe installation device comprises the following working steps:
