Description

Technical Field

[0001] The invention relates to the technical field of building construction noise control, and in particular to a modularly assembled mobile soundproof cover for a construction site. Background Art

[0002] In construction sites, the noise generated by various mechanical equipment and the noise of construction workers often have a great impact on the surrounding environment and personnel. Traditional noise control generally uses walls such as colored steel tiles to enclose the construction site. Although it can reduce noise propagation to a certain extent, the sound insulation effect is poor; in the publication number: CN110295786B, a sound insulation retaining wall for construction sites is disclosed. Two pairs of slots are opened on the side walls opposite to the two adjacent side pillars and the side pillars and the corner pillars. Partitions are respectively inserted into the two pairs of slots. Although the sound insulation effect is improved compared with colored steel tiles, residents in the middle and high floors are still disturbed by noise. At the same time, there are problems such as complex installation and difficulty in moving. Especially in the scene of construction sites where frequent changes of positions and the use of different equipment are required, these problems are particularly prominent.

[0003] Therefore, there is an urgent need for a soundproof enclosure that is modularly assembled, easy to move and has good sealing properties. Summary of the invention

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See also Figure 1-Figure 12The present invention provides a technical solution: a modular assembled mobile soundproof cover for a construction site, comprising a double-groove track 1, a pair of double-groove tracks 1 are provided and are arranged in parallel, the double-groove tracks 1 are arranged on both sides of the construction site, a fixing hole 6 is provided on the surface of the double-groove track 1, a limiting cylinder 7 is fixedly connected to the bottom of the double-groove track 1 and is located at a position corresponding to the fixing hole 6, the bottom end of the limiting cylinder 7 is inserted into the ground to avoid lateral movement, and the double-groove track 1 is fixed by inserting anchor nails into the fixing hole 6 and driving them below the ground or using screws and other fixing methods.

[0041] An outer soundproof cover 2 and an inner soundproof cover 3 are arranged on the top of the double groove track 1. The cross sections of the outer soundproof cover 2 and the inner soundproof cover 3 are both arch structures. The sizes of the outer soundproof cover 2 and the inner soundproof cover 3 are inconsistent. The outer soundproof cover 2 is located outside the inner soundproof cover 3. The outer soundproof cover 2 is slidably connected to the outer track of the double groove track 1, and the inner soundproof cover 3 is slidably connected to the inner track of the double groove track 1. The distance between the inner surface of the outer soundproof cover 2 and the outer surface of the inner soundproof cover 3 is 1-5cm. By covering the construction site with a soundproof cover, the impact of noise on the surrounding environment is reduced, especially the impact on middle and high-rise residents. At the same time, the soundproof cover can also cover the messy scene of the construction site.

[0042] The outer sound insulation cover 2 has the same overall structure as the inner sound insulation cover 3. The outer sound insulation cover 2 includes two angle adjustment bases 21. Double-groove pulleys 22 are fixedly connected to both sides of the bottom of the angle adjustment base 21. A first sound insulation board 23 is fixedly connected to the top of the angle adjustment base 21. A second sound insulation board 24 is provided at one end of the first sound insulation board 23 away from the angle adjustment base 21. The first sound insulation board 23 and the second sound insulation board 24 are rotatably connected by a hinge 25. The ends of the two second sound insulation boards 24 away from the hinge 25 are fixed by a quick connection device 26. The two first sound insulation boards 23 and the two second sound insulation boards 24 form an arch structure. The angle between the first sound insulation board 23 and the horizontal ground can be changed by adjusting the angle of the base 21. On the one hand, the width of the entire sound insulation cover can be adjusted by changing the angle between the first sound insulation board 23 and the horizontal ground, which makes it easier to adjust the width of the sound insulation cover according to the construction site. On the other hand, when transporting in a disassembled state, when the first sound insulation board 23 is adjusted to be perpendicular to the horizontal ground, the second sound insulation board 24 on one side is parallel to the first sound insulation board 23 through the connection of the hinge 25, which makes it more convenient to transport using the double-groove pulley 22, thereby improving the efficiency of transportation.

[0043] The quick connection device 26 can more quickly connect and fix the two second sound insulation panels 24 to form an arch structure, and is also designed to improve the efficiency of disassembly and assembly.

[0044] Sealing limit strips 4 are provided at both ends of the outer sound insulation cover 2, and convex strips 5 are fixedly connected to the surface of the inner sound insulation cover 3 close to one side of the outer sound insulation cover 2 and close to both ends. The convex strips 5 are in contact with one side of the sealing limit strips 4 to achieve a tight connection between the outer sound insulation cover 2 and the inner sound insulation cover 3, thereby improving the sealing performance. At the same time, sealing rubber pads are provided at the hinges 25 and the quick connection device 26. The sealing rubber pads can cover the gaps at the connections, further improving the sealing performance and the sound insulation effect. Construction can even be continued in the sound insulation cover in light rainy weather, thereby reducing the impact of weather factors on the construction period.

[0045] Specifically, the angle adjustment base 21 includes a first fixed plate 211 and a second fixed plate 212. The bottom of the first fixed plate 211 is fixedly connected to the double-groove pulley 22. The surface of the first fixed plate 211 is fixedly connected to a first rotating block 213, and a plurality of first rotating blocks 213 are provided. The surface of the second fixed plate 212 is fixedly connected to a second rotating block 214, and the second rotating block 214 is provided at a corresponding position between two adjacent first rotating blocks 213. The first rotating block 213 and the second rotating block 214 are rotatably connected through a fixed shaft 215. The first fixed plate 211 and the second rotating block 214 are rotatably connected through the fixed shaft 215. The fixed plate 212 can be rotated to adjust the angle; a slide groove 216 is provided on one side of the second rotating block 214, and a clamping groove 217 is provided on the side of the first rotating block 213 close to the slide groove 216. The first fixed tooth block 218 is slidably connected in the slide groove 216 and the clamping groove 217. The first fixed tooth block 218 is fixedly connected to the fixed shaft 215. The length of the slide groove 216 is greater than the thickness of the first fixed tooth block 218, and the length of the clamping groove 217 is less than the thickness of the first fixed tooth block 218. The first fixed tooth block 218 is driven to slide between the slide groove 216 and the clamping groove 217 through the axial movement of the fixed shaft 215. During specific operation, when adjusting the angle, the first fixed tooth block 218 is driven to move into the slide groove 216 through the fixed shaft 215. When the angle adjustment is completed, the first fixed tooth block 218 is driven to move into the clamping groove 217 through the fixed shaft 215. Since the length of the clamping groove 217 is less than the thickness of the first fixed tooth block 218, one side of the first fixed tooth block 218 is also located in the slide groove 216. Therefore, the angle between the first fixed plate 211 and the second fixed plate 212 is fixed by the first fixed tooth block 218, the clamping groove 217 and the slide groove 216. At the same time, the number of teeth of the first fixed tooth block 218 is designed to adjust the adjustment accuracy. For example, if a fixed tooth block with 36 teeth is used, the adjustment accuracy is 10°. If a fixed tooth block with 45 teeth is used, the adjustment accuracy is 8°. The clamping groove 217 and the slide groove 216 are arranged to be tooth grooves adapted to the first fixed tooth block 218.

[0046] To prevent the fixed shaft 215 from falling off, one end of the fixed shaft 215 is fixedly connected to a first limiting plate 219, and the other end of the fixed shaft 215 is fixedly connected to a second limiting plate 2110. A first spring 2111 is arranged between the first limiting plate 219 and the adjacent first rotating block 213. The first spring 2111 facilitates the first fixed tooth block 218 to move into the slot 217.

[0047] The quick connection device 26 includes a bottom frame 261 and a mounting plate 262. The bottom frame 261 is mounted on one end of the second sound insulation board 24 on the left or right side, and the mounting plate 262 is mounted on one end of the other second sound insulation board 24. A third rotating block 263 is fixedly connected to one side of the mounting plate 262. A plurality of third rotating blocks 263 are provided. A fixed cylinder seat 264 is fixedly connected to one side of the bottom frame 261. The fixed cylinder seat 264 is provided at a corresponding position between two adjacent third rotating blocks 263. A second fixed tooth block 267 is symmetrically slidably connected in the fixed cylinder seat 264. The inner wall of the fixed cylinder seat 264 is provided with a tooth groove 2611 adapted to the second fixed tooth block 267. A fixing pin 268 is fixedly connected to one side of the tooth block 267, the second fixed tooth block 267 is coaxially arranged with the fixing pin 268, a fixing seat 265 is fixedly connected to the middle part of the fixed cylinder seat 264, both ends of the fixing seat 265 are fixedly connected to the first guide rod 266, the center of the second fixed tooth block 267 and the fixing pin 268 is slidably connected to the first guide rod 266, and the design of the first guide rod 266 improves the stability of the second fixed tooth block 267 and the fixing pin 268, and a rotating hole 269 and a limiting groove 2610 are provided at one end of the third rotating block 263 close to the fixing pin 268, and the center of the rotating hole 269 and the center of the limiting groove 2610 are on the same straight line.

[0048] The length of the tooth groove 2611 is greater than the thickness of the second fixed tooth block 267, ensuring that the second fixed tooth block 267 can be connected to the tooth groove 2611 during the sliding process. The length of the limiting groove 2610 is less than the thickness of the second fixed tooth block 267, ensuring that one side of the second fixed tooth block 267 is still located in the tooth groove 2611 after entering the limiting groove 2610. The length of the fixing pin 268 is greater than the length of the limiting groove 2610. The limiting groove 2610 is located at the end of the third rotating block 263, ensuring that the fixing pin 268 is connected to the rotating hole 269 when the second fixed tooth block 267 does not enter the limiting groove 2610. At this time, the two second sound insulation boards 24 have been rotationally connected; a driving structure for driving the two second fixed tooth blocks 267 to move toward or away from each other is provided in the bottom frame 261.

[0049] When connecting the two second sound insulation boards 24, the fixing pin 268 is first located in the fixing cylinder seat 264 through the driving structure, and the two second sound insulation boards 24 are made close to each other by rotating the second sound insulation boards 24 and one end of the fixing pin 268 is aligned with the rotating hole 269. The fixing pin 268 is moved into the rotating hole 269 along its axial direction by the driving structure. At this time, the two second sound insulation boards 24 are rotationally connected with the rotating hole 269 through the fixing pin 268. However, since the second sound insulation board 24 is rotationally connected with the first sound insulation board 23 through the hinge 25, the overall structure is not stable at this time. By adjusting the positions of the two second sound insulation boards 24, the second sound insulation boards 24 on both sides are symmetrically arranged. At this time, the second fixing tooth block 267 is driven by the driving structure to be inserted into the limiting groove 2610 to ensure that the angle between the two second sound insulation boards 24 does not change, thereby improving the overall stability. Compared with the traditional screw fixed connection, the quick connection device 26 is used to achieve quick fixation on the basis of convenient angle adjustment, thereby improving the efficiency of disassembly and assembly.

[0050] The driving structure includes a rotating rod 2612 and a threaded block 2614. The rotating rod 2612 is arranged in the bottom frame 261 and both ends are rotatably connected to the inner wall of the bottom frame 261. One end of the rotating rod 2612 extends to the outside of the bottom frame 261 and is fixedly connected to a hexagonal block 2616. The hexagonal block 2616 is convenient for using a tool to drive the rotation of the rotating rod 2612. The surface of the rotating rod 2612 is provided with left-handed threads 2613 at a corresponding position of the fixed cylinder seat 264. The left side of the left-handed threads 2613 is a left-handed thread and the right side is a right-handed thread. The two threaded blocks 2614 are threadedly connected to the left-handed threads 2613 and are symmetrically arranged. A connecting plate 2615 is fixedly connected between one end of the threaded block 2614 and one side of the second fixed tooth block 267. The rotation of the rotating rod 2612 can drive the two second fixed tooth blocks 267 to move toward or away from each other.

[0051] The first sound insulation board 23 has the same structure as the second sound insulation board 24. The first sound insulation board 23 includes an outer frame 231, a protective layer 232, a sound insulation layer 233 and a sound absorbing layer 234. The outer frame 231 is a rectangular structure. The protective layer 232, the sound insulation layer 233 and the sound absorbing layer 234 are arranged in the outer frame 231 and fixedly connected to the outer frame 231. The protective layer 232 adopts PVC weather-resistant board, polyurethane weather-resistant board, plastic steel weather-resistant board, the sound insulation layer 233 adopts sound insulation felt or fiberboard, and the sound absorbing layer 234 adopts polyester fiber sound absorbing board or sound insulation cotton. The sound insulation layer 233 is arranged between the protective layer 232 and the sound absorbing layer 234, and the sound absorbing layer 234 is arranged on the side close to the noise source. The protective layer 232 improves the protection of the sound insulation layer 233 and the sound absorbing layer 234 materials, and the sound insulation layer 233 and the sound absorbing layer 234 improve the sound insulation effect.

[0052] The sealing limit strip 4 includes a fixed frame 41, inside of which a partition 42 is fixedly connected along its length direction, a sealing strip 43 is arranged between one side of the partition 42 and the fixed frame 41, and a stabilizing plate 416 is fixedly connected between the other side of the partition 42 and the fixed frame 41, and support tubes 44 are arranged at equal intervals on one side of the top of the inner wall of the fixed frame 41, a slider 45 is slidably connected in the support tube 44, and the bottom end of the slider 45 is fixedly connected to a first rack 46, the sealing strip 43 is fixed to the bottom of the first rack 46 by a fixing screw 47, and a sealing pad is arranged at the bottom end of the sealing strip 43 to improve the sealing effect.

[0053] A support seat 48 is fixedly connected to the top of the inner wall of the fixed frame 41 and located on one side of the support tube 44. The bottom of the support seat 48 is rotatably connected to a gear 49 meshing with the first rack 46. One side of the gear 49 is also meshingly connected to a second rack 410. The second rack 410 is vertically arranged and the bottom end extends to the bottom of the stabilizing plate 416 and is fixedly connected to an inclined block 411. The surface of the stabilizing plate 416 is provided with a through hole adapted to the second rack 410. The second rack 410 is driven upward by the inclined block 411, and the first rack 46 on one side is driven downward by the gear 49. A guide rail 413 is fixedly connected to one side of the inner wall of the fixed frame 41, and a guide block 412 is slidably connected to the surface of the guide rail 413. One side of the guide block 412 is fixedly connected to the second rack 410. A second guide rod 414 is fixedly connected to the top of the inner wall of the fixed frame 41 and directly above the second rack 410. The guide block 412 and the second rack 410 are slidably connected to the second guide rod 414. A second spring 415 is arranged between the top of the guide block 412 and the top of the inner wall of the fixed frame 41. The stability of the second rack 410 is improved by the guide rail 413, the guide block 412 and the second guide rod 414. The arranged second spring 415 ensures that the second rack 410 moves to the bottom when the inclined block 411 is not under pressure.

[0054] When the inner soundproof cover 3 is opened, the convex strip on one side of the inner soundproof cover 3 contacts the inclined block 411, driving the second rack 410 to move upward, and driving the first rack 46 to move downward through the gear 49, so that the sealing strip 43 moves toward the surface of the inner soundproof cover 3 until one side of the inner sealing strip 43 is tightly fitted with the soundproof cover 3. At this time, due to the existence of the gear 49, the inclined block 411 cannot continue to drive the second rack 410 to move upward, limiting the further movement of the inner soundproof cover 3. It is achieved that the sealing limit strip 4 is used to improve the sealing performance and limit the movement of the inner soundproof cover 3.
