DETAILED DESCRIPTION

[0029] In order to make the purpose, technical scheme and advantages of the application clearer, the application is further described in detail below in combination with embodiments and drawings, and the illustrative embodiments of the application and the description thereof are used to explain the application, but not to limit the application.

[0030] As Figs. 1-3As shown, the road and bridge sound insulation guard structure provided by the embodiment of the application comprises a stand column 1, a guard body 2 and a sound insulation plate 3. The stand column 1 is provided with a first connecting assembly 4, and the bottom of the stand column 1 is used for being connected to the two sides of a road. The guard body 2 is connected with the stand column 1 to form a protection on the two sides of the road. The sound insulation plate 3 is detachably connected with the guard body 2 to make the plate surfaces of the two adhere to each other. The sound insulation plate 3 is further rotationally connected with the top of the guard body 2. The sound insulation plate 3 is provided with a second connecting assembly. The second connecting assembly is detachably connected with the first connecting assembly 4 after the sound insulation plate 3 is rotated.

[0031] During maintenance, the connection between the sound insulation plate 3 and the guard body 2 is first released, and then force is applied to the top of the sound insulation plate 3 to make the sound insulation plate 3 rotate on the guard body 2 until the plate surface of the sound insulation plate 3 is perpendicular to the length direction of the stand column 1, that is, the outer plate surface of the sound insulation plate 3 is vertically upward. Finally, the first connecting assembly 4 and the second connecting assembly are connected to keep the state of the sound insulation plate 3. The staff can clean the top plate surface of the sound insulation plate 3 by using a cleaning tool.

[0032] The road and bridge sound insulation guard structure provided by the embodiment of the application can keep the state of the sound insulation plate 3 by rotationally connecting the sound insulation plate 3 with the guard body 2 and by providing the first connecting assembly 4 and the second connecting assembly. The outer plate surface of the sound insulation plate 3 can be vertically upward after being rotated. The staff can conveniently clean the outer plate surface of the sound insulation plate 3. The cleaning tool does not need to be placed outside the sound insulation plate 3, and the risk of falling of the cleaning tool is smaller. The staff can intuitively and conveniently check the cleaning effect of the outer plate surface of the sound insulation plate 3, and the maintenance process is more convenient.

[0033] In some optional embodiments, a connecting strip hole 6 is formed in the guard body 2. A connecting bolt 7 is arranged on the sound insulation plate 3 and is adapted to pass through the connecting strip hole 6. After being connected with a connecting nut, the sound insulation plate 3 and the guard body 2 are tightly adhered to each other.

[0034] In the embodiment of the application, the connecting strip hole 6 is arranged to allow the connecting bolt 7 to enter the connecting strip hole 6 in a rotating state. Finally, the connecting nut is arranged to tightly adhere the sound insulation plate 3 to the guard body 2, thereby ensuring the stability of the connection between the sound insulation plate 3 and the guard body 2 and preventing the sound insulation plate 3 and the guard body 2 from being frequently impacted due to accidental rotation between the sound insulation plate 3 and the guard body 2 in a vibrating state.

[0035] In some optional embodiments, a receiving groove 8 is formed in the sound insulation plate 3, and an elastic member 13 is arranged in the receiving groove 8. Part of the structure of the elastic member 13 is located outside the receiving groove 8 to elastically contact the guard body 2.

[0036] In the embodiment of the present application, during the installation process, or after the sound insulation plate 3 is cleaned, the sound insulation plate 3 needs to be rotated to the position of being attached to the guard plate body 2. Through the setting of the elastic member 13, when the sound insulation plate 3 is close to the guard plate body 2, the elastic member 13 can provide a buffering force to avoid the insufficient force from causing the sound insulation plate 3 to collide with the guard plate body 2 during the rotation process, thereby protecting the structure of the sound insulation plate 3 and the guard plate body 2 from being damaged.

[0037] In some optional embodiments, the elastic member 13 is a coil spring.

[0038] In the embodiment of the present application, the coil spring is easy to obtain and can provide a relatively stable elastic force. Since the sound insulation plate 3 is prevented from contacting the guard plate body 2 by rotation, the reaction force caused by the guard plate body 2 to the coil spring is not strictly along the axial direction of the coil spring. Therefore, when the coil spring is selected and installed, the elastic coefficient of the coil spring can be appropriately larger, and the part of the coil spring located outside the accommodating groove 8 is shorter. In this way, when the coil spring contacts the guard plate body 2, the direction of the reaction force provided by the guard plate body 2 is closer to the axial direction of the coil spring, so that the bending phenomenon of the coil spring when contacting the guard plate body 2 can be avoided.

[0039] In some optional embodiments, the connecting bolt 7 is located in the accommodating groove 8, and the elastic member 13 is sleeved on the connecting bolt 7.

[0040] In the embodiment of the present application, the elastic member 13 is a coil spring, and after the elastic member 13 is sleeved on the connecting bolt 7, the connecting bolt 7 can limit the elastic member 13 to a certain extent, which can prevent the coil spring from being bent. This means that the elastic coefficient of the coil spring can be relatively small, and the part of the coil spring located outside the accommodating groove 8 can be longer. On the one hand, when the distance between the sound insulation plate 3 and the surface of the guard plate body is large, the coil spring can contact the guard plate body to provide a buffering effect earlier, thereby reducing the risk of collision between the sound insulation plate 3 and the guard plate body. On the other hand, during the connection process of the sound insulation plate 3 and the guard plate body, the force required to make the sound insulation plate 3 and the surface of the guard plate body adhere to each other is smaller, and the operation process is convenient and labor-saving.

[0041] In some optional embodiments, the steel plate 9 is connected to the hole edge of the connecting strip hole 6.

[0042] In this embodiment, when the elastic element 13 is provided, due to the elastic force provided by the elastic element 13, the sound insulation plate 3 and the protective plate will not be in contact with each other when an external force is applied, but will form a certain angle. This means that the length direction of the connecting bolt 7 will also form an angle with the surface of the protective plate, rather than being perpendicular. During the operation of the connecting nut, as the connecting nut rotates, the connecting nut will contact the edge of the hole 6 on the protective plate. As the connecting nut continues to rotate, the length direction of the connecting bolt 7 will gradually become perpendicular to the surface of the protective plate. During this process, the position of the connecting nut at the edge of the hole 6 will also change, which means that the connecting nut will generate a certain amount of friction with the protective plate body 2. The protective plate body 2 itself is made of concrete. Under frequent friction conditions, the edge of the hole 6 will experience severe wear. After the steel plate 9 is provided, the connecting nut contacts the steel plate 9, and rotating the connecting nut will not damage the concrete structure of the protective plate body 2.

[0043] In some optional embodiments, the first connecting component 4 is configured as a steel ring; the second connecting component includes a support base 10 and a pin 11, the support base 10 is connected to the top of the column 1, and the pin 11 is elastically slidably connected to the support base 10 so that the pin 11 can insert into / avoid the steel ring in the extended / retracted state.

[0044] In this embodiment, the support base 10 is provided with a pin hole, and the pin 11 is movably inserted into the pin hole. A spring can be connected between the pin 11 and the wall of the pin hole to realize the elastic sliding of the pin 11. Both ends of the pin 11 are located on both sides of the support base 10. One end of the pin 11 is used to insert a steel ring, and the other end is used for operation by the staff. In use, the staff first operates the other end of the pin 11, so that one end of the pin 11 moves closer to the support base 10, and rotates the sound insulation plate 3 so that the outer surface of the sound insulation plate 3 is vertically upward. The steel ring facilitates the alignment of the pin 11. The pin 11 is released, and the pin 11 enters the steel ring under the action of elasticity to limit the rotation of the sound insulation plate 3. The sound insulation plate 3 is maintained in its state, and the staff can then easily clean the sound insulation plate 3.

[0045] In some alternative embodiments, a pull ring handle 12 is provided at one end of the pin 11.

[0046] In this embodiment, the pull ring handle 12 helps to improve the ease of operation for staff.

[0047] In some alternative embodiments, the steel ring is configured such that when the surface of the sound insulation panel 3 is perpendicular to the length direction of the column 1, there is a gap between the lower end of the steel ring and the pin 11.

[0048] In the embodiment of the present application, when the force on the sound insulation plate 3 is removed, the sound insulation plate 3 can rotate by a certain angle based on the self-weight to make the lower end of the steel ring contact the pin shaft 11, at this time, the plate surface of the sound insulation plate 3 will be inclined, when water is used to flush the sound insulation plate 3, under the flow guiding effect of the sound insulation plate 3, the water can flow out of the outside of the guard plate structure, that is, the two sides of the road, thereby reducing the accumulated water in the road.

[0049] In some optional embodiments, the top of the guard plate body 2 is arranged in a suspended manner with a rotating shaft, in actual implementation, two installation seats arranged at intervals can be arranged at the bottom of the guard plate body 2, the rotating shaft is located between the two installation seats and the two ends of the rotating shaft are connected with the two installation seats respectively; the rotating seat is arranged on the sound insulation plate 3, the rotating hole is arranged on the rotating seat, and the rotating hole is rotationally matched with the rotating shaft through the bearing.

[0050] In the embodiment of the present application, the bearing can ensure the smooth rotation between the sound insulation plate 3 and the guard plate body 2, which is beneficial to the improvement of operation convenience.

[0051] In some optional embodiments, the rotating shaft and the installation seat are detachably connected, the top of the sound insulation plate 3 is provided with a lifting hook, so that after the lifting machine is matched with the lifting hook, the connection between the rotating shaft and the installation seat and the connection between the connecting bolt 7 and the connecting nut are contacted, the separation of the sound insulation plate 3 and the guard plate body is realized through the lifting of the lifting machine, of course, during the lifting process, the worker can use the jacking rod to pass through the connecting strip hole 6 to jack the sound insulation plate 3 away from the guard plate body 2, so as to prevent the connecting bolt 7 from interfering with the guard plate body 2 during the lifting process.
