Description

Technical Field

[0001] This application relates to the technical field of rail transit noise reduction, and particularly relates to a fully enclosed sound barrier and an installation method thereof. Background Art

[0002] With the progress of society and the development of cities, people's living standards have been continuously improved, and urban transportation has become the problem most closely related to us. The completion of a large number of highways and the opening of urban light rails have brought great convenience to our travel. However, the residents living near these highways and light rails are suffering from the impact of traffic noise. In order to reduce the impact of traffic noise on the residents near highways and light rails, various sound absorption barrier plates are generally installed on both sides of the road and around the light rail.

[0003] The Chinese utility model patent with the application number CN2021206286347 discloses a new type of fully enclosed sound barrier, which includes a steel structure frame fixed on both sides of the road. Sound insulation units are fixedly assembled on the left and right sides of the steel structure frame. Sound absorption units are fixedly arranged on the left and right sides of the top of the steel structure frame. A ventilation and noise elimination unit is fixedly assembled in the middle of the top of the steel structure frame. The noise elimination unit is used to absorb the traffic noise inside the sound barrier, so as to reduce the noise near highways and light rails.

[0004] In view of the above related technologies, the ventilation and noise elimination unit is erected on the top of the fully enclosed sound barrier and is located at the center of the top of the fully enclosed sound barrier. Since the ventilation and noise elimination unit itself has a certain weight, during construction, support columns need to be added at the center of the fully enclosed sound barrier. Due to different road conditions, the construction of the support columns is more complex and time-consuming; and for different sections, the types of sound insulation units to be installed are also different, including louvered sound absorption plates, concave-convex perforated sound absorption plates, flat perforated sound absorption plates or concave-convex perforated louvered sound absorption plates. Therefore, it is also more complex to assemble the sound insulation units on the steel structure frame, resulting in low construction efficiency. Summary of the Invention

[0006] In a first aspect, a fully enclosed sound barrier provided by this application adopts the following technical solutions:

[0008] By adopting the above technical solution, when the cable reel is rotated, the cable reel tightens the cable, so that the cable exerts a reaction force on the cross beam, improving the stability of the cross beam after installing the ventilation component, and there is no need to construct support columns separately. While the cable reel rotates, the mounting rod can be rotated through the transfer component, thereby adjusting the mounting surface of the mounting rod, and then rotating the mounting groove on the mounting surface, so that the mounting groove with the same end face shape as the first sound absorption board rotates to the installation position, and the first sound absorption board is installed in the mounting groove, which is convenient for assembling various types of sound absorption boards and improving the construction efficiency of the fully enclosed sound barrier.

[0009] Optionally, the transfer component includes a first bevel gear set and a second bevel gear set. The first bevel gear set is connected to the end of the mounting rod close to the cross beam, the second bevel gear set is connected to the cable reel, and a connecting shaft is provided between the first bevel gear set and the second bevel gear set. The connecting shaft is rotatably connected to the support rod.

[0010] By adopting the above technical solution, when the cable reel is rotated, the cable reel can drive the second bevel gear set to operate, and the second bevel gear set can drive the first bevel gear set to operate through the connecting shaft, thereby transmitting the rotational force of the cable reel to the mounting rod, so that the mounting rod can be rotated while the cable reel is rotated.

[0011] Optionally, the first bevel gear set includes a first connecting wheel and a second connecting wheel. The first connecting wheel is connected to the mounting rod and is used to drive the mounting rod to rotate. The second connecting wheel meshes with the first connecting wheel.

[0015] Optionally, the wire winding member includes a wire locking disc, a positioning cylinder and a positioning disc. The wire locking disc is fixedly connected to one end of the wire winding wheel close to the mounting rod. The positioning cylinder is fixedly connected to one end of the support rod close to the wire winding wheel. The positioning cylinder is sleeved on the rotating shaft. The positioning disc is connected to the positioning cylinder. A placement groove is formed at one end of the wire locking disc close to the positioning disc. A plurality of ratchet teeth are circumferentially arranged on the inner circumference of the wire locking disc in the placement groove. The positioning disc is located in the placement groove. A positioning buckle is rotatably connected to the side wall of the positioning disc close to the ratchet teeth. The positioning buckle can fit with the ratchet teeth to fix the wire locking disc.

[0016] By adopting the above technical solution, when the wire winding wheel is rotated, the ratchet gear in the wire locking disc forms a locking relationship with the positioning buckle, so that the wire locking disc can only rotate in one direction, which is convenient for fixing the wire winding wheel and reduces the possibility of the cable slack before fixing the cable.

[0017] Optionally, an elastic member is arranged on one side of the positioning buckle away from its rotating end, and the elastic member is used to push the positioning buckle into the ratchet teeth.

[0018] By adopting the above technical solution, when the locking disc is rotated, the positioning buckle is pressed by the ratchet teeth under the action of the elastic member. After being pressed, the positioning buckle is popped out again with the rotation, so that the positioning buckle can limit the ratchet teeth, thereby realizing the one-way rotation of the locking disc.

[0019] Optionally, a reset pin is provided on one side of the positioning buckle close to the elastic member, a reset arc groove is formed on the positioning disk, the reset arc groove communicates with the placement cavity, and the reset pin can move in an arc along the reset arc groove.

[0020] By adopting the above technical solution, when it is necessary to release the linkage of the rotating shaft to the second bevel gear set, the reset pin is pressed down, and the wire winding wheel is used to tighten the cable alone.

[0021] Optionally, an adjusting rod is provided at the top end of the support rod, the top end of the adjusting rod is higher than the cross beam, and the cable passes through the end of the adjusting rod higher than the cross beam and is wound around the wire winding wheel.

[0022] By adopting the above technical solution, the adjusting rod supports the cable between the cross beam and the support rod, so that a triangular tension area is formed among the cable, the cross beam and the support rod, and the stability of the cross beam near the ventilation member is improved.

[0023] On the other hand, the present application also provides an installation method applicable to a fully enclosed sound barrier among the above.

[0028] S4. Engage the positioning buckle with the ratchet teeth in the wire locking disk, rotate the rotating shaft, the rotating shaft drives the wire winding wheel to wind the cable, and at the same time rotate the adapter, so that the adapter rotates the mounting rod, thereby adjusting the mounting surfaces on the two spaced mounting rods, so that the mounting grooves on the two symmetrical mounting surfaces have the same shape as the mounting end surfaces of the first sound absorption board.

[0029] S5. Insert the first sound absorption board into the mounting groove and adjust the mounting position of the first sound absorption board.

[0030] S6. Press the reset pin, the positioning buckle disengages from the ratchet teeth in the wire locking disk, rotate the rotating shaft, tighten the cable again, after fixing the cable, release the fixation of the reset pin and fix the wire winding wheel.

[0031] By adopting the above technical solution, the cable is tensioned by the cable winding wheel, and the cable exerts a tensile force on one end of the cross beam close to the ventilation member, so that no additional support columns need to be provided below the ventilation member inside the fully enclosed sound barrier, reducing the construction period. At the same time, the cable winding wheel can choose whether to rotate the adapter simultaneously according to the rotation of the support rod. When the cable winding wheel can drive the adapter to rotate, the adapter can drive the mounting rod to rotate and adjust the mounting surface of the mounting rod.

[0033] 1. By setting the cable and the cable winding wheel, the cable winding wheel is used to tighten the cable. At the same time, an adapter is connected to the cable winding wheel, and the adapter is connected to the mounting rod. When the cable winding wheel rotates, the cable winding wheel can drive the adapter to rotate the mounting rod simultaneously, so that while tightening the cable, the mounting rod on one side of the support rod is rotated, facilitating the assembly of various types of sound-absorbing panels, and can also tighten one end of the cross beam close to the ventilation member, facilitating the construction of the fully enclosed sound barrier, thereby improving the construction efficiency of the fully enclosed sound barrier.

[0046] An embodiment of the present application discloses a fully enclosed sound barrier.

[0047] Referring to Figure 1 , Figure 2 , a fully enclosed sound barrier includes a support assembly 1, a tensioning assembly 2 and a mounting assembly 3; a plurality of support assemblies 1 are arranged at intervals along the advancing direction of the track. In this embodiment, four support assemblies 1 are provided. Each support assembly 1 includes two symmetrically arranged support rods 11. Cross beams 12 are welded on two side walls of the two support rods 11 that are close to each other. The top of the cross beam 12 has an outward convex arc. A ventilation member 13 is welded between the cross beams 12. The ventilation member 13 is an exhaust fan. A top plate 14 for closing the support assembly 1 is welded between the cross beams 12. The top plate 14 is also a sound absorption board. The top plate 14 can be a transparent sound insulation board or a closed sound insulation board.

[0048] Referring to Figure 2 , Figure 3, the tensioning assembly 2 includes a cable 21 and a cable reel 22. The cable 21 is a steel cable. One end of the cable 21 is installed on one end of the cross beam 12 close to the ventilation assembly through a fixing seat. The cable reel 22 is rotatably connected to the side of the support rod 11 away from the cross beam 12. To facilitate the tensioning of the cross beam 12, an adjusting rod 15 is welded to the top of the support rod 11. The height of the adjusting rod 15 can be selected according to the radian of the cross beam 12, and it is only necessary that the top of the adjusting rod 15 is higher than the vertex height of the cross beam 12. One end of the cable 21 away from the ventilation member 13 passes through the end of the adjusting rod 15 higher than the cross beam 12 and is wound around the cable reel 22. There is a fixing member on the cable reel 22 for fixing the cable reel 22. The fixing member is a bolt, and the fixing member passes through the end of the cable reel 22 and is threadedly connected to the support rod 11. The fixing member is not shown in the figure.

[0049] Referring to Figure 4 , Figure 5 , the installation assembly 3 includes an installation rod 31. The installation rod 31 is rotatably connected to the support rod 11 through a rotating shaft. The axis of the installation rod 31 is the same as the high side direction of the support rod 11. The installation rod 31 is provided with a plurality of installation surfaces 311. In this embodiment, the installation rod 31 is provided with four installation surfaces 311. The four installation surfaces 311 are circumferentially arranged along the rotation center axis of the installation rod 31. Installation grooves 312 are formed on all four installation surfaces 311 and the shapes of the installation grooves 312 are different. The installation grooves 312 are used to install the first sound-absorbing board 4. The first sound-absorbing board 4 includes a louver-type sound-absorbing board, a concave-convex perforated sound-absorbing board, a flat perforated sound-absorbing board or a concave-convex perforated louver sound-absorbing board. The shapes of the four installation grooves 312 can correspond to the shapes of the end faces of the louver-type sound-absorbing board, the concave-convex perforated sound-absorbing board, the flat perforated sound-absorbing board or the concave-convex perforated louver sound-absorbing board. When installing the louver-type sound-absorbing board, the concave-convex perforated sound-absorbing board, the flat perforated sound-absorbing board or the concave-convex perforated louver sound-absorbing board, rotate the installation grooves 312 on the two symmetric installation rods 31 to the same-shaped side and install the first sound-absorbing board 4, which is convenient for assembling various types of sound-absorbing boards.

[0050] Referring to Figure 6 , the installation assembly 3 further includes an adapter 32. The adapter 32 is connected to the cable reel 22 and can rotate simultaneously with the cable reel 22. The adapter 32 is used to transmit the rotational force of the cable reel 22 to the installation rod 31, and the adapter 32 is used to drive the installation rod 31 to rotate.

[0051] Specifically, referring to Figure 6 , Figure 7 , the adapter 32 includes a first bevel gear set 321 and a second bevel gear set 322. The first bevel gear set 321 is connected to one end of the installation rod 31 close to the cross beam 12. The second bevel gear set 322 is connected to the cable reel 22. There is a connecting shaft 3213 between the first bevel gear set 321 and the second bevel gear set 322. The connecting shaft 3213 is rotatably connected to the support rod 11 through a fixing seat.

[0052] Further, referring to Figure 7 , the first bevel gear set 321 includes a first connecting wheel 3211 and a second connecting wheel 3212. The first connecting wheel 3211 is key-connected to the mounting rod 31. When the first connecting wheel 3211 rotates, it can drive the mounting rod 31 to rotate. The second connecting wheel 3212 meshes with the first connecting wheel 3211. When the first connecting wheel 3211 rotates, it can drive the second connecting wheel 3212 to rotate. The end face of the second connecting wheel 3212 is parallel to the side wall of the support rod 11 away from the cross beam 12. The second connecting wheel 3212 is key-connected to the connecting shaft 3213. Both the first connecting wheel 3211 and the second connecting wheel 3212 are bevel gears. The second bevel gear set 322 includes a third connecting wheel 3221 and a fourth connecting wheel 3222. The third connecting wheel 3221 is key-connected to one end of the connecting shaft 3213 away from the second connecting wheel 3212. Both the second connecting wheel 3212 and the third connecting wheel 3221 are key-connected to the connecting shaft 3213. When the second connecting wheel 3212 drives the rotation, the connecting shaft 3213 drives the third connecting wheel 3221 to rotate. The fourth connecting wheel 3222 meshes with the third connecting wheel 3221. Therefore, when the third connecting wheel 3221 rotates, it can drive the fourth connecting wheel 3222 to rotate. A rotating shaft 221 is coaxially welded on the winding wheel 22. The fourth connecting wheel 3222 is key-connected to the rotating shaft 221. When the fourth connecting wheel 3222 rotates, it can drive the rotating shaft 221 to rotate. Both the third connecting wheel 3221 and the fourth connecting wheel 3222 are also bevel gears. Conversely, when the rotating shaft 221 rotates, it can not only drive the winding wheel 22 to rotate to wind the cable 21, but also drive the fourth connecting wheel 3222 to rotate, so that the fourth connecting wheel 3222 drives the third connecting wheel 3221 to rotate, the third connecting wheel 3221 drives the connecting shaft 3213 to rotate, the connecting shaft 3213 drives the second connecting wheel 3212 to rotate, and the second connecting wheel 3212 drives the first connecting wheel 3211 to rotate, so that the first connecting wheel 3211 can drive the mounting rod 31 to rotate, and thus rotate the mounting groove 312 on the periphery of the mounting rod 31 to the mounting surface 311 where the end of the first sound absorption board 4 is adapted. In order to facilitate the rotation of the rotating shaft 221, a rotating handle is detachably connected to one end of the rotating shaft 221 away from the winding member 23. The detachable connection method can be bolt fixed connection or plug connection. In this embodiment, it is plug connection. By applying a reaction force to the cross beam 12 through the cable 21, it is tightened to improve the stability of the fully enclosed sound barrier and improve the construction efficiency of the fully enclosed sound barrier.

[0053] Referring to Figure 6 , Figure 7 , the tensioning assembly 2 further includes a winding member 23. The winding member 23 is connected to the winding wheel 22. The winding member 23 is used to rotate and fix the winding wheel 22. The winding member 23 is a one-way rotation structure.

[0054] Specifically, referring to Figure 7 and Figure 8 , the winding member 23 includes a wire locking disc 231, a positioning cylinder 234 and a positioning disc 235. The wire locking disc 231 is welded to one end of the winding wheel 22 close to the mounting rod 31. The positioning cylinder 234 is fixedly connected to one end of the support rod 11 close to the winding wheel 22 through a fixing seat. The positioning cylinder 234 is sleeved on the rotating shaft 221, and the positioning disc 235 is welded to the positioning cylinder 234. A placement groove 232 is formed at one end of the wire locking disc 231 close to the positioning disc 235. The placement groove 232 is circular. A plurality of ratchet teeth 233 are circumferentially arranged on the inner circumference of the wire locking disc 231 in the placement groove 232. The positioning disc 235 is located in the placement groove 232. A positioning buckle 237 is rotatably connected to the side wall of the positioning disc 235 close to the ratchet teeth 233 through a rotating shaft. The positioning buckle 237 can be attached to the ratchet teeth 233 to fix the wire locking disc 231. The positioning buckle 237 is in the shape of a cuboid.

[0055] Referring to Figure 9 , a placement cavity 236 is formed in the positioning disc 235. The positioning buckle 237 is located in the placement cavity 236. An elastic member 238 is provided on one side of the positioning buckle 237 away from its rotating end. The elastic member 238 is a spring. One end of the elastic member 238 is welded to the lower surface of the positioning buckle 237, and the other end is welded to the positioning disc 235. The compression direction of the elastic member 238 is vertical compression. The elastic member 238 is used to push the positioning buckle 237 into the ratchet teeth 233. A reset pin 239 is welded to one side of the positioning buckle 237 close to the elastic member 238. A reset arc groove is formed in the positioning disc 235. The center of the reset arc groove coincides with the rotation center of the positioning buckle 237. The reset arc groove communicates with the placement cavity 236. The reset pin 239 can move in an arc along the reset arc groove. Pressing the reset pin 239 can release the limit of the positioning buckle 237 on the wire locking disc 231, and the winding wheel 22 can be rotated alone to adjust the tension of the cable 21.

[0056] The implementation principle of an all - enclosed sound barrier in an embodiment of the present application is as follows: After installing the support assembly 1, installation rods 31 are symmetrically arranged between every two spaced - apart support rods 11.
