Description

Technical Field

[0001] This utility model relates to the field of sound insulation board fixing technology, and in particular to a novel road and bridge sound insulation board fixing device. Background Technology

[0002] With the acceleration of urbanization, road traffic flow is constantly increasing, and noise pollution around roads and bridges is becoming increasingly serious. Sound insulation panels, as an effective facility to reduce traffic noise, are widely used on both sides of roads and bridges, while fixing devices are used to fix the sound insulation panels and connect them to the bridge.

[0003] Existing fixing devices typically use multiple support rods and bolts to fix the sound insulation panels. Because the support rods are fixed in position, the sound insulation panels that can be fixed are limited to a certain size, and the device occupies a large volume, making it inconvenient to carry. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the existing technology: the existing fixing device usually uses multiple support rods and bolts to fix the sound insulation board. Since the position of the support rods is fixed, the sound insulation board that can be fixed can only be of a certain size, and the device occupies a large volume and is not convenient to carry. Therefore, the proposed new road and bridge sound insulation board fixing device is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A novel road and bridge sound insulation board fixing device includes a base. A rectangular groove is formed on the upper surface of the base. A rotating rod is symmetrically and horizontally rotatably installed in the rectangular groove. A support plate is fixedly sleeved on the rotating rod. The two rotating rods are controlled to rotate relative to each other by a drive assembly. A storage groove is formed on the surface of the support plate. A rotating shaft is symmetrically and rotatably installed in the storage groove. A support rod is fixedly sleeved on the rotating shaft. A rotating opening is formed at one end of the support rod. A round rod is rotatably installed in the rotating opening. A T-shaped abutment is fixedly sleeved on the round rod.

[0007] The support plate has a mounting block fixedly installed on its surface. The mounting block has a first through-hole on its surface. A bolt is movably connected in the first through-hole. The upper surface of the base has symmetrical mounting grooves for threaded installation of two bolts. The abutment plate has multiple second through-holes on its surface.

The threads on the surfaces of the two second threaded rods are in opposite directions. One end of the rotating rod is provided with a threaded groove. The surface of the base is symmetrically provided with openings that are respectively connected to the two threaded grooves. One end of each of the two second threaded rods passes through the two openings and is threaded into the two threaded grooves respectively.

[0009] Preferably, a contact plate is fixedly installed on both sides of the base, and mounting holes are symmetrically opened on the upper surface of the contact plate. An expansion screw for connecting with the bridge is movably connected in the mounting hole.

[0010] Preferably, the rectangular groove is provided with a reinforcement component, which is used to assist in fixing the sound insulation board.

[0011] Preferably, the auxiliary fastening assembly includes a third threaded rod with opposite thread directions at its left and right ends and two symmetrical T-shaped clamps threaded onto the third threaded rod. The bottom of the rectangular groove has a mounting groove, and the front and rear walls of the rectangular groove both have vertically formed grooves communicating with the mounting groove. The third threaded rod is horizontally rotatably installed in the mounting groove, and one end is fixedly mounted with an installation rod. One end of the installation rod protrudes from the base. The top horizontal plane of the third threaded rod is lower than the bottom horizontal plane of the rectangular groove, and the thickness of the T-shaped clamps is less than the depth of the grooves.

[0012] Preferably, magnets are fixedly embedded in the inner walls of the two abutments located in the storage slot, and the abutments are made of stainless steel.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figures 1-10 A new type of road and bridge sound insulation board fixing device includes a base 1. A rectangular groove 2 is provided on the upper surface of the base 1. A rotating rod 3 is symmetrically and horizontally rotatably installed in the rectangular groove 2. A support plate 4 is fixedly sleeved on the rotating rod 3. The two rotating rods 3 are controlled to rotate relative to each other by a drive assembly. A storage groove 5 is provided on the surface of the support plate 4. A rotating shaft is symmetrically and rotatably installed in the storage groove 5. A support rod 6 is fixedly sleeved on the rotating shaft. A rotating opening is provided at one end of the support rod 6. A round rod is rotatably installed in the rotating opening. A T-shaped abutment 7 is fixedly sleeved on the round rod.

[0028] Mounting blocks 8 are fixedly installed on the surface of the support plate 4. The surface of the mounting block 8 has a first through hole, and a bolt 9 is movably connected in the first through hole. The upper surface of the base 1 has symmetrical mounting grooves 10 for threaded installation of two bolts 9. The surface of the abutment plate 7 has multiple second through holes, and fastening screws 11 are movably connected in the second through holes. Contact plates 17 are fixedly installed on both sides of the base 1. The upper surface of the contact plates 17 has symmetrical mounting holes 18, and expansion bolts 19 for connection with the bridge are movably connected in the mounting holes 18.

[0029] When the device is being carried, both support plates 4 are horizontally positioned within the rectangular slots 2, and multiple support rods 6 are located within the two storage slots 5. The device is then rectangular, significantly reducing its volume and making it easy to carry. When the device is needed, the drive assembly first controls the relative rotation of the two support plates 4, rotating them 90 degrees until they are vertically aligned with the base 1. At this point, the two first through-holes align with the positions of the two mounting slots 10. Then, the bottom ends of the two bolts 9, which are movably connected to the two first through-holes, are threaded into the two mounting slots 10. After tightening the screws, insert the bottom of the sound insulation board to be fixed into the rectangular groove 2 and place the sound insulation board in the center of the rectangular groove 2. Then, rotate the multiple support rods 6 until the surface of the abutment plate 7 at the end of the support rod 6 is in contact with the side wall of the sound insulation board. Then, make screw grooves on the side wall of the sound insulation board corresponding to the positions of multiple mounting holes 18. Then, pass multiple fastening screws 11 through multiple second through holes, so that their ends are threaded into multiple screw grooves and tightened to complete the fixing of the sound insulation board. Then, fix the base 1 to the bridge through the expansion screws 19 located in the mounting holes 18.

[0030] Since all the support rods 6 can rotate, and the abutment plate 7 located at one end of the support rod 6 can also rotate, as long as the support rod 6 is rotated so that the surface of the abutment plate 7 at the end of the support rod 6 is in contact with the side wall of the sound insulation board, and then it can be fixed by multiple fastening screws 11, it can fix sound insulation boards of different sizes, making it highly practical.

[0031] The drive assembly includes a first threaded rod 12 rotatably mounted on the surface of the base 1, a slide plate 13 threadedly sleeved on the first threaded rod 12, and two second threaded rods 14 symmetrically fixedly mounted on the surface of the slide plate 13. The threads on the surfaces of the two second threaded rods 14 are in opposite directions. One end of the rotating rod 3 is provided with a threaded groove 15. The surface of the base 1 is symmetrically provided with through holes 16 that are respectively connected to the two threaded grooves 15. One end of each of the two second threaded rods 14 passes through the two through holes 16 and is threadedly mounted in the two threaded grooves 15 respectively.

[0032] By rotating the first threaded rod 12, the sliding plate 13, which is threaded onto the first threaded rod 12, is controlled to move the two second threaded rods 14 laterally. Since the second threaded rods 14 cannot rotate, under the cooperation between the threads and the thread grooves 15 on the surface of the second threaded rods 14, when the two second threaded rods 14 move laterally, the two rotating rods 3 will respectively carry the two support plates 4 to rotate relative to each other.

[0033] The rectangular groove 2 is equipped with a fixing component, which is used to assist in fixing the sound insulation board. The fixing component includes a third threaded rod 20 with opposite thread directions at both ends and two symmetrical T-shaped clamps 21 that are threaded onto the third threaded rod 20. The bottom of the rectangular groove 2 is provided with a placement groove. The front and rear walls of the rectangular groove 2 are vertically provided with grooves 22 that communicate with the placement groove. Both sides of the T-shaped clamps 21 are in sliding contact with the groove wall of the placement groove, which can restrict the rotation of the T-shaped clamps 21. The third threaded rod 20 is horizontally rotatably installed in the placement groove, and one end is fixedly installed with an installation rod. One end of the installation rod protrudes from the base 1. The top horizontal plane of the third threaded rod 20 is lower than the bottom horizontal plane of the rectangular groove 2. The thickness of the T-shaped clamps 21 is less than the depth of the groove 22.

[0034] Since the top horizontal plane of the third threaded rod 20 is lower than the bottom horizontal plane of the rectangular groove 2, when the bottom of the sound insulation board contacts the bottom of the rectangular groove 2, it will not disengage from the third threaded rod 20. In the initial state, the two T-shaped clamps 21 will slide and be embedded in the two grooves 22 respectively, without affecting the two support plates 4 being horizontally stored in the rectangular groove 2. After the sound insulation board is moved to a suitable position in the rectangular groove 2, the two T-shaped clamps 21 can be moved relative to each other by rotating the third threaded rod 20 until the sides of the two T-shaped clamps 21 that are close to each other are tightly abutted against the surface of the sound insulation board, thus completing the auxiliary fixation of the sound insulation board. The surface of the T-shaped clamps 21 is bonded with a rubber layer, which can increase the friction between itself and the contact surface of the sound insulation board.

[0035] Magnets are fixedly embedded in the inner walls of the two abutment plates 7 located in the storage slot 5. The abutment plates 7 are made of stainless steel. When the two support rods 6 are both stored in the storage slot 5, the two abutment plates 7 located at their ends can be controlled to attract each other. The magnetic attraction of the magnets can be used to fix the two support rods 6 and the two abutment plates 7 located in the storage slot 5 with simple magnetic force, so as to prevent the support rods 6 and the abutment plates 7 from rotating arbitrarily under the action of gravity when the support plate 4 is controlled to rotate.

[0036] In this invention, in the initial state, every two support rods 6 are stored in the storage slot 5, and the two support plates 4 are horizontally stored in the rectangular slot 2, thereby greatly reducing the size of the device and making it easy to carry. When needed, the support rods 6 and support plates 4 can be quickly rotated and the sound insulation panels of different sizes can be fixed, improving the practicality of the device.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
