Description

Technical Field

[0001] This utility model relates to the field of sound barrier installation technology, specifically to a device for installing sound barriers on viaducts. Background Technology

[0002] In noise reduction projects for transportation infrastructure such as bridges and viaducts, sound barriers are key devices for effectively controlling the propagation of traffic noise. Their installation efficiency and construction quality directly affect the project progress and noise reduction effect. In existing technologies, sound barriers are mostly installed using a double-column support structure, that is, an installation frame is formed by two fixed columns erected opposite each other, and the main body of the sound barrier is installed between the two columns, using the matching structure on the columns to achieve positioning and fixation.

[0003] For example, Chinese patent CN115058994B discloses a rapid installation device for bridge insert-type metal sound barriers. By setting a cooperative structure of grooves, balls and fixing frames, it realizes the smooth sliding insertion of sound insulation panels and improves the installation efficiency of sound insulation panels. At the same time, it adopts a split limiting plate and column snap-fit ​​structure, which simplifies the pre-installation process of the columns.

[0004] However, in actual construction, there are still obvious shortcomings when using conventional hoisting methods to install the sound barrier between the two columns:

[0005] Due to the large size of the sound barrier, its position is easily affected by external factors during hoisting, making it difficult to accurately align with the installation structure on the column. The small clearance between the installation structure and the sound barrier further increases the alignment difficulty. This forces operators to repeatedly adjust the crane, reducing construction efficiency and potentially causing damage to components due to repeated attempts, even posing certain safety hazards.

[0006] Therefore, in order to address the difficulties in alignment and cumbersome operation during the hoisting of sound barriers between double columns, there is an urgent need for a technical solution that can guide the sound barrier to be quickly and accurately embedded into the column installation structure, so as to make up for the shortcomings of existing technologies and ensure the efficiency and quality of sound barrier construction. Utility Model Content

[0007] The purpose of this invention is to provide a device for installing sound barriers on viaducts, which solves the problems of difficult alignment and cumbersome operation when hoisting sound barriers between double columns, enables the sound barrier to be quickly and accurately embedded into the column installation structure, improves installation efficiency and quality, and reduces component damage and safety risks.

[0008] This utility model provides the following technical solution: a device for installing a sound barrier on an elevated bridge, including a base, a bracket fixed above the base, and a hoisting mechanism for driving the sound barrier to rise and fall in the vertical direction on the bracket;

[0009] The base is equipped with omnidirectional casters at its bottom;

[0010] The base is fixed with a positioning plate on its side. The two ends of the positioning plate are used to abut against the surfaces of the two barrier mounting columns so that the plane where the sound barrier is located coincides with the mounting groove of the barrier mounting column in the vertical direction.

[0011] The base surface is provided with a horizontal correction mechanism, which includes a base plate disposed on the base surface. A horizontal guide rail is fixed on the surface of the base plate. Two push plates are slidably connected to the horizontal guide rail, and the horizontal guide rail is connected to a drive mechanism that drives the two push plates to move outward and abut against the opposite surfaces of the two barrier mounting columns.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Existing sound barriers are not easy to align with the mounting slot during installation. This utility model, by installing positioning plates on the side of the base, allows the sound barrier to be quickly positioned on a vertical plane coinciding with the mounting slot when the base is moved close to the two barrier mounting columns. This achieves the initial positioning of the sound barrier. After the initial positioning of the sound barrier is completed, the two push plates can be driven by the drive mechanism to move away from each other and abut against the inner side of the two barrier mounting columns, achieving the secondary positioning of the sound barrier. This allows the sound barrier to be accurately inserted into the mounting slot when the lifting mechanism lowers the sound barrier. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4This utility model discloses a device for installing a sound barrier on an elevated bridge. Specifically, it is a device for facilitating the alignment of the sound barrier 3 with the mounting slot of the barrier mounting column 7. It includes a base 1, a bracket 2 fixed above the base 1, and a hoisting mechanism 4 on the bracket 2 for lifting and lowering the sound barrier 3 in the vertical direction. The structure of this utility model for installing a sound barrier on an elevated bridge is similar to that of existing sound barrier installation devices, such as the device for installing a sound barrier on an elevated bridge disclosed in announcement number CN222613999U. In use, the sound barrier 3 is lifted by the hoisting mechanism 4, then the device is moved close to the barrier mounting column 7, and then the sound barrier 3 is placed into the mounting slot of the barrier mounting column 7 by the hoisting mechanism 4.

[0019] In the existing technology, when the sound barrier 3 is hoisted by the hoisting mechanism 4, it is not convenient to position the sound barrier 3, making it difficult for the sound barrier 3 to directly enter the mounting slot of the barrier mounting column 7 when it is lowered. This requires the installers to make multiple adjustments. To solve this problem, the main improvement of this utility model is as follows:

[0020] The bottom of the base 1 is equipped with universal casters 5. The universal casters 5 make it easy to move the base 1 and adjust its position. It should be noted that the universal casters 5 can be existing casters with braking function. When the device is moved to the appropriate position, the braking function will fix it to prevent movement during the installation process and ensure the stability of the installation.

[0021] A positioning plate 6 is fixed to the side of the base 1. The two ends of the positioning plate 6 are used to abut against the surfaces of the two barrier mounting columns 7 so that the plane where the sound barrier 3 is located coincides with the mounting groove of the barrier mounting column 7 in the vertical direction. With the setting of the positioning plate 6, the base 1 can be pushed to move during use. By abutting between the two barrier mounting columns 7 at the two ends of the positioning plate 6, it is convenient to move the sound barrier 3 to the vertical plane that coincides with the mounting groove of the barrier mounting column 7.

[0022] It is understandable that when the sound barrier 3 coincides with the plane of the mounting groove, the two ends of the sound barrier 3 may not be aligned with the two ends of the mounting groove. In order to further adjust the position of the sound barrier 3, the surface of the base 1 is provided with a horizontal correction mechanism 8. The horizontal correction mechanism 8 includes a base plate 81 set on the surface of the base 1. A horizontal guide rail 82 is fixed on the surface of the base plate 81. Two push plates 83 are slidably connected to the horizontal guide rail 82. The horizontal guide rail 82 is connected to a drive mechanism 9 that drives the two push plates 83 to move outward and abut against the opposite surfaces of the two barrier mounting columns 7. With the above structure, after the positioning plate 6 abuts against the surface of the two barrier mounting columns 7, the drive mechanism 9 can drive the two push plates 83 to move away from each other and abut against the inner side of the two barrier mounting columns 7, so that the base 1 automatically centers between the two barrier mounting columns 7 under the support of the universal rollers 5, thereby achieving precise positioning of the sound barrier 3.

[0023] A slider 84 is slidably mounted inside the horizontal guide rail 82. A push plate 83 is fixed to the slider 84 via a connecting rod 85. The drive mechanism 9 includes a dual-head motor 91 fixed inside the horizontal guide rail 82. The output shaft of the dual-head motor 91 is connected to a screw 92, which is threadedly connected to the slider 84. The dual-head motor 91 can be a servo motor of model 60ST-M00630. When the external power supply of the dual-head motor 91 is turned on, the two output shafts of the dual-head motor 91 simultaneously drive the screw 92 connected to it to rotate. Since the screw 92 is threadedly connected to the slider 84, and the slider 84 can only slide horizontally inside the horizontal guide rail 82 and cannot rotate with the screw 92, the rotational motion of the screw 92 is converted into the linear motion of the slider 84 along the horizontal guide rail 82. Since the push plate 83 is fixed to the slider 84 via the connecting rod 85, the movement of the slider 84 will drive the push plate 83 to move synchronously, so that the two push plates 83 move outward and abut against the opposite surfaces of the two barrier mounting columns 7, thereby completing the horizontal correction and positioning.

[0024] In some embodiments, the base plate 81 is movably disposed on the surface of the base 1, and a telescopic cylinder 10 is connected between the base plate 81 and the base 1. With the above structure, when positioning the sound barrier 3 before installation, the telescopic cylinder 10 can drive the base plate 81 into the space between the two barrier mounting columns 7. The drive mechanism 9 drives the two push plates 83 to move away from each other and abut against the inner side of the two barrier mounting columns 7 to achieve the positioning of the sound barrier 3. Then, the hoisting mechanism 4 can drive the sound barrier 3 to move downward into the interior of the mounting slot. During the installation of the sound barrier 3, the telescopic cylinder 10 can be shortened to drive the base plate 81 back to the surface of the base 1 to avoid obstructing the sound barrier 3 when it falls.

[0025] The push plate 83 is preferably U-shaped. Specifically, the outer side of the push plate 83 has a slot. When the push plate 83 moves outward and abuts against the inner side of the barrier mounting column 7, the barrier mounting column 7 can be just inserted into the slot, thereby limiting the base 1 and preventing the base 1 from moving during the installation process.

[0026] The support 2 includes a vertical guide rail 21 fixed to the surface of the base 1. A lifting frame 22 is movably installed within the vertical guide rail 21. The hoisting mechanism 4 is an electric hoist fixed to the lifting frame 22. The electric hoist is an existing structure and will not be described in detail here. Sound barrier guide components 11 are fixed on both sides of the lifting frame 22 to guide the vertical movement of the sound barrier 3. In some embodiments, the sound barrier guide components 11 include channel steel fixed to both sides of the lifting frame 22. It is understood that the cross-section of the channel steel is U-shaped, and the side of the sound barrier 3 can be inserted into the groove of the channel steel for limiting. Through the above structure, the connection between the sound barrier 3 and the hoisting mechanism 4 is achieved. When using mechanism 4, the sound barrier 3 to be installed can be placed on the surface of the base 1, that is, below the hoisting mechanism 4. Then, the lifting frame 22 is moved downward, driving the electric hoist and the channel steel downward, so that the upper end of the sound barrier 3 is inserted into the groove of the channel steel for limiting. Then, it is tied to the side of the sound barrier 3 by means of binding ropes and other structures. Then, the binding ropes are hung on the wire rope of the electric hoist. Next, the lifting frame 22 is moved upward, driving the electric hoist and the sound barrier 3 as a whole to move upward to the upper end of the bracket 2. In this way, after the positioning of the device is completed, the sound barrier 3 can be placed vertically into the installation groove of the barrier installation column 7 by extending the wire rope of the electric hoist.

[0027] The vertical guide rail 21 is equipped with a lifting mechanism 12 for driving the movement of the lifting frame 22, such as... Figure 2 As shown, the lifting mechanism 12 includes a servo motor 121 fixed to the upper end of the vertical guide rail 21 and a lifting screw 122 rotatably installed in the vertical guide rail 21. The lifting screw 122 is threadedly connected to the lifting frame 22. The output shaft of the servo motor 121 is fixed to the upper end of the lifting screw 122. In use, the external power supply of the servo motor 121 is turned on, and the rotation of the output shaft of the servo motor 121 drives the lifting screw 122 to rotate. The rotation of the lifting screw 122 drives the lifting frame 22 to move in the vertical guide rail 21.

[0028] The steps for installing the sound barrier 3 using the device for installing sound barriers on elevated bridges according to this utility model are as follows:

[0029] S1. Place the sound barrier 3 on the surface of the base 1, lower the lifting frame 22 so that the channel steel 11 engages with the upper end of the sound barrier 3, connect the sound barrier 3 to the electric hoist with the binding rope, start the lifting mechanism 12, and lift the sound barrier 3 to the upper end of the support 2. S2. Push the device to the installation area so that the two ends of the positioning plate 6 abut against the surfaces of the two barrier mounting columns 7. At this time, the plane of the sound barrier 3 is vertically aligned with the mounting groove. S3. Start the dual-head motor 91 to drive the push plate 83 to move outward and abut against the opposite surfaces of the two barrier mounting columns 7, so that the device is centered and aligned between the two barrier mounting columns 7, and completes precise alignment.

[0030] S4. Control the electric hoist to lower the sound barrier 3 so that it is embedded in the installation slot; then control the push plate 83 to reset and the telescopic cylinder 10 to retract the base plate 81, continue to lower the sound barrier 3 until it is fully inserted into the installation slot, and untie the binding rope to complete the installation.
