Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, specifically a noise reduction device for railway engineering construction. Background Technology

[0002] The power machinery and construction equipment used in railway construction cause serious noise pollution to the original environment. This noise pollution significantly disrupts the lives of nearby residents, leading to disputes and complaints. Therefore, soundproofing devices are typically installed on-site during construction.

[0003] A search revealed a patent with application number 202321366157.7, which discloses a noise reduction device for railway engineering construction. The device includes a base with sound-insulating and sound-absorbing panels mounted on it. The base also has a protective plate for protection, and a support plate for mounting the protective, sound-insulating, and sound-absorbing panels. The bottom of the support plate is fixedly connected to the base, and the middle and upper parts are connected to the protective, sound-insulating, and sound-absorbing panels via detachable devices. The sound-insulating panels include vacuum sound-insulating panels and filled sound-insulating panels. Detachable weighting components are also provided on both sides of the base, and a dust sprayer is installed on the top of the support plate. However, in practical use, this noise reduction device has a fixed size, making it impossible to adjust its length according to different construction scenarios and noise reduction requirements, thus limiting its applicability and practicality. Therefore, we propose a noise reduction device for railway engineering construction. Utility Model Content

[0024] Please see Figure 1-6 A noise reduction device for railway engineering construction includes a first support base 1 and a second support base 2. The bottom of both the first support base 1 and the second support base 2 is fixedly connected to a base 3. The base 3 is made of high-strength cast iron, which has good wear resistance and pressure resistance and can withstand the weight of the device itself and the external impact that may occur during construction. Triangular stabilizing blocks 4 are fixedly connected to the front and rear sides of the first support base 1 and the second support base 2. The bottom of the triangular stabilizing blocks 4 is fixedly connected to the top of the base 3. By utilizing the stability principle of triangles, the stability of the entire device is greatly enhanced, so that it can remain stable in complex construction environments and is not easy to shake or tip over. The first support base 1 and the second support base 2 are connected by a noise reduction component 5.

[0025] The noise reduction component 5 includes a first sound insulation plate 501, a second sound insulation plate 502, a sliding groove 503, a sliding column 504, a sliding sleeve 505, a limiting groove 506, a fixing frame 507, a guide groove 508, a guide plate 509, a lead screw 510, a threaded hole 511, a handle 512, and a limiting plate 513. The first sound insulation plate 501 is fixedly connected to the front right side of the first support base 1. The first sound insulation plate 501 is in movable contact with the base 3, and the right side of the first sound insulation plate 501 is in movable contact with the left side of the second support base 2.

[0026] The rear side of the first sound insulation panel 501 is movably connected to the second sound insulation panel 502. The left side of the second sound insulation panel 502 is in movable contact with the right side of the first support base 1. The right side of the second sound insulation panel 502 is fixedly connected to the left side of the second support base 2. The second sound insulation panel 502 is in movable contact with the base 3.

[0027] Both the first sound insulation panel 501 and the second sound insulation panel 502 are made of damping sound insulation panels, which can effectively absorb and block the noise generated during construction.

[0028] The first sound insulation panel 501 has sliding grooves 503 on the upper and lower rear sides. The left and right sides of the inner wall of the sliding groove 503 are fixedly connected by a sliding column 504. A sliding sleeve 505 is slidably fitted on the left side of the surface of the sliding column 504. The sliding sleeve 505 is slidably connected to the sliding groove 503. The rear side of the sliding sleeve 505 is fixedly connected to the front side of the second sound insulation panel 502.

[0029] The rear side of the first sound insulation panel 501 has multiple limiting grooves 506 arranged from left to right, and the rear side of the second sound insulation panel 502 is fixedly connected to a fixing bracket 507.

[0030] The top and bottom of the inner wall of the fixing frame 507 are provided with guide grooves 508. The two guide grooves 508 are slidably connected to each other at the front by a guide plate 509. The rear side of the guide plate 509 is rotatably connected to a lead screw 510 by a bearing. The rear side of the fixing frame 507 is provided with a threaded hole 511 corresponding to the position of the lead screw 510. The rear end of the lead screw 510 passes through the threaded hole 511 and extends to the outside of the threaded hole 511 and is fixedly connected to a handle 512. The lead screw 510 and the threaded hole 511 are threadedly connected.

[0031] A limiting plate 513 is fixedly connected to the front side of the guide plate 509. A through opening is provided on the rear side of the second sound insulation plate 502 corresponding to the position of the limiting plate 513. The front side of the limiting plate 513 passes through the through opening and the limiting groove 506 in sequence and extends into the interior of the limiting groove 506. The limiting plate 513 is movably inserted into the through opening and movably engaged with the limiting groove 506.

[0032] In practical applications: When the length of the noise reduction device needs to be adjusted, the operator rotates the handle 512 counterclockwise. The handle 512 drives the lead screw 510 to rotate. Since the lead screw 510 is threadedly connected to the threaded hole 511, the lead screw 510 will move axially within the threaded hole 511 when it rotates. Because the guide plate 509 is slidably connected to the guide groove 508 on the inner wall of the fixing frame 507, the rotation of the guide plate 509 is restricted. Therefore, when the lead screw 510 rotates, it will drive the guide plate 509 to move backward along the guide groove 508, thereby causing the limiting plate 513 to retract from the limiting groove 506, releasing the first sound insulation plate 501 and the second sound insulation plate 506. 02. Limiting the relative position, then pull the first support seat 1 or the second support seat 2 to change the relative position of the first sound insulation plate 501 and the second sound insulation plate 502, thereby adjusting the length of the noise reduction device. When the appropriate length is reached, rotate the handle 512 clockwise to make the lead screw 510 drive the guide plate 509 and the limiting plate 513 to move forward. The limiting plate 513 passes through the opening on the second sound insulation plate 502 and is inserted into the corresponding limiting groove 506 on the rear side of the first sound insulation plate 501, thereby fixing the relative position of the first sound insulation plate 501 and the second sound insulation plate 502, ensuring that the noise reduction device works stably at the adjusted length.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
