Description

Technical Field

[0001] This utility model relates to the technical field of highway noise control and auxiliary facility installation, and in particular to an adjustable soundproof cover fixing device for highways. Background Technology

[0002] Highways are a crucial infrastructure for modern transportation. With increasing traffic volume, the noise generated by vehicles has a significant impact on the surrounding environment. To reduce noise pollution, soundproof enclosures are widely used along highways as an effective noise reduction measure. Soundproof enclosures are typically installed and supported by fixing devices. Depending on the usage scenario and environmental requirements, these fixing devices need to be adaptable, stable, and convenient. The fixing devices for soundproof enclosures are generally made of metal or composite materials, and their design must balance strength and installation flexibility. However, in practical applications, due to differences in terrain conditions and construction needs, the fixing devices are often difficult to adjust quickly in terms of height and angle, resulting in low installation efficiency.

[0003] Chinese patent CN219948515U discloses an easy-to-install ship collision avoidance device, including a mounting base. The mounting base has a working groove and an opening inside. A motor is installed inside the working groove, and a first gear is connected to the power drive end of the motor. A double-acting screw is connected inside the working groove, and a second gear is installed at the center of the outer side of the double-acting screw. Two symmetrical movable seats are connected to the outside of the double-acting screw. A connecting seat is connected inside the opening. A connecting plate is installed on the upper surface of the connecting seat, and a base is installed on the upper surface of the connecting plate. Two symmetrical buffer components are installed on the top of the base. A frame is installed on the top of the two buffer components, and several sets of collision avoidance rollers are connected to the top of the frame. Workers can quickly install and disassemble the collision avoidance device, improving work efficiency. The first and second springs ensure effective buffering, and the entire buffering process is stable.

[0004] However, in the process of conceiving and implementing the above application, the inventors discovered that the disclosed solution, in actual use, requires a separate power source to drive the bidirectional screw driven by a motor to insert the locking pin into the slot on the side wall of the connector for easy assembly and disassembly, which is relatively expensive.

The inside of the protective sleeve is filled with lubricant to reduce friction loss.

[0009] The outer edge of the limiting plate has a plurality of limiting holes evenly distributed. The locking assembly includes a pin and a return spring. One end of the pin is inserted into the limiting hole, and the other end is slidably connected to the adjusting plate. The return spring is sleeved on the outside of the pin. One end of the return spring contacts the middle stepped surface of the pin, and the other end contacts the inner wall of the adjusting plate.

[0022] like Figures 1 to 3 The present invention provides an adjustable soundproof cover fixing device for highways, the main components of which include a base 1, a support frame 2, a sliding groove 3, a lifting block 4, an adjusting plate 5, a fixing clamp 6, an angle adjustment mechanism, a drive mechanism, an elastic element 14, and an auxiliary support mechanism. The height and angle adjustment functions of the soundproof cover are achieved through the combination and cooperation of these components.

[0023] The base 1 serves as the basic structure of the entire device, and a support frame 2 is welded to its top. The support frame 2 is vertically arranged and has sufficient strength to support the components above. A sliding groove 3 is provided on the inner wall of the support frame 2. The sliding groove 3 has a T-shaped cross section to facilitate its cooperation with the lifting block 4. The sliding groove 3 extends along the height direction of the support frame 2 to provide guidance for the up and down movement of the lifting block 4. The cross-sectional shape of the lifting block 4 matches the sliding groove 3, and ball bearings are provided on both sides of the lifting block 4. The ball bearings contact the inner wall of the sliding groove 3 to reduce frictional resistance and make the lifting block 4 move more smoothly.

[0024] One side of the lifting block 4 is hinged to the adjusting plate 5 via a first connecting rod. The two ends of the first connecting rod are connected to the lifting block 4 and the adjusting plate 5 respectively via pins, thus realizing the hinged relationship between the two. When the lifting block 4 moves up and down along the sliding groove 3, it drives the adjusting plate 5 to move up and down synchronously via the first connecting rod. An elastic element 14 is provided between the bottom of the adjusting plate 5 and the base 1. The elastic element 14 is composed of a compression spring. One end of the compression spring is fixedly connected to the bottom of the adjusting plate 5, and the other end is fixedly connected to the top of the base 1. A protective sleeve is provided on the outside of the compression spring. The two ends of the protective sleeve are fixedly connected to the adjusting plate 5 and the base 1 respectively. The inside of the protective sleeve is filled with lubricant to reduce the frictional loss of the compression spring during the extension and contraction process.

[0025] A fixing clamp 6 is installed on the top of the adjusting plate 5. The fixing clamp 6 is used to hold the soundproof cover. The fixing clamp 6 includes an upper clamp plate and a lower clamp plate. The upper clamp plate and the lower clamp plate are connected by bolts. Both ends of the bolts are provided with locking nuts. By tightening the locking nuts, the soundproof cover can be firmly fixed between the upper clamp plate and the lower clamp plate. The inner side of the upper clamp plate and the lower clamp plate are provided with anti-slip pads. The surface of the anti-slip pads is provided with wavy grooves. This design increases the friction between the soundproof cover and the clamp to prevent the soundproof cover from sliding or loosening during use.

[0026] An angle adjustment mechanism is provided on the outer side of the fixed clamp 6. The angle adjustment mechanism includes a rotating shaft 7, a limiting plate 8, and a locking assembly 9. The rotating shaft 7 passes through the fixed clamp 6 and is rotatably connected to the adjusting plate 5. Both ends of the rotating shaft 7 are rotatably connected to the fixed clamp 6 and the adjusting plate 5 through bearings. The outer ring of the bearing is interference-fitted with the inner wall of the fixed clamp 6 and the adjusting plate 5, and the inner ring of the bearing is interference-fitted with the outer wall of the rotating shaft 7. The limiting plate 8 is fixed to one end of the rotating shaft 7. Multiple limiting holes are evenly distributed on the outer edge of the limiting plate 8. The locking assembly 9 is used to lock the limiting plate 8 to the adjusting plate 5. The relative position is locked between the two. The locking assembly 9 includes a pin and a return spring. One end of the pin is inserted into the limiting hole, and the other end is slidably connected to the adjusting plate 5. The return spring is sleeved on the outside of the pin. One end of the return spring contacts the middle stepped surface of the pin, and the other end contacts the inner wall of the adjusting plate 5. The return spring is always in a compressed state to push the pin to move towards the limiting plate 8, thereby ensuring the position lock between the limiting plate 8 and the adjusting plate 5. The surface of the limiting plate 8 is provided with radially distributed anti-slip textures. This design increases the friction during operation and prevents slippage.

[0027] The other side of the lifting block 4 is provided with a drive mechanism, which includes a threaded rod 12, a handwheel 13 and a guide sleeve. One end of the threaded rod 12 is threadedly connected to the lifting block 4, and the other end passes through the support frame 2 and extends to the outside. The handwheel 13 is fixed to the extended end of the threaded rod 12. By rotating the handwheel 13, the threaded rod 12 can be rotated, thereby driving the lifting block 4 to move up and down along the sliding groove 3. The guide sleeve is fixed on the inner side wall of the support frame 2. The threaded rod 12 passes through the guide sleeve to ensure that it maintains linear motion during rotation. The outer side of the threaded rod 12 is provided with scale marks. The scale marks are used to indicate the moving distance of the lifting block 4, so as to facilitate precise control of the height of the adjustment plate 5.

[0028] The auxiliary support mechanism includes a telescopic rod 10 and a support foot 11. One end of the telescopic rod 10 is hinged to the bottom of the base 1, and the other end is hinged to the support foot 11. The bottom of the support foot 11 is provided with an anti-slip pad, which can increase the friction between the support foot 11 and the ground and improve the stability of the overall device. The outside of the telescopic rod 10 is provided with a positioning bolt, which is used to fix the length of the telescopic rod 10. By adjusting the length of the telescopic rod 10, it can adapt to the installation requirements under different terrain conditions.

[0029] The outer side of the support frame 2 is provided with reinforcing ribs. The two ends of the reinforcing ribs are welded to the support frame 2 and the base 1 respectively. The cross section of the reinforcing ribs is triangular. This design improves the stability of the overall structure and ensures that the device is not easily deformed or tilted under complex working conditions.

[0030] In practical use, firstly, adjust the length of the telescopic rod 10 of the auxiliary support mechanism according to the site terrain conditions and fix the position of the telescopic rod 10 by positioning bolts to ensure that the base 1 is placed stably on the ground. Then, place the soundproof cover between the upper and lower clamping plates of the fixing clamp 6 and fix the soundproof cover by tightening the locking nuts at both ends of the bolts. Adjust the height of the soundproof cover as needed by rotating the handwheel 13 to rotate the threaded rod 12, which drives the lifting block 4 to move up and down along the sliding groove 3. Then, through the first connecting rod, the adjusting plate 5 and the fixing clamp 6 move up and down synchronously. By observing the scale marks on the threaded rod 12, the height of the soundproof cover can be precisely controlled. If it is necessary to adjust the angle of the soundproof cover, manually rotate the fixing clamp 6 to rotate it around the rotating shaft 7 and the limiting plate 8 rotates accordingly. When the required angle is reached, the locking assembly 9 locks the position between the limiting plate 8 and the adjusting plate 5 to complete the angle adjustment.

[0031] The above detailed embodiments describe the composition and connection relationships of the various components of this utility model; at the same time, they explain how the various components work together to achieve the height and angle adjustment functions of the soundproof enclosure, allowing for flexible installation and adjustment of the soundproof enclosure through manual operation to meet the usage needs in different scenarios. To better enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0032] First, adjust the length of the telescopic rod 10 in the auxiliary support mechanism according to the site terrain conditions. After loosening the positioning bolts and stretching the telescopic rod 10 to the appropriate length, tighten the positioning bolts again to ensure that the base 1 can be stably placed on the ground. The bottom of the telescopic rod 10 is hinged to the support foot 11, and the bottom of the support foot 11 is equipped with anti-slip pads, which can provide reliable stability under different terrain conditions and prevent the device from tilting or sliding due to uneven ground.

[0033] Next, place the soundproof cover between the upper and lower clamping plates of the fixing clamp 6. Tighten the locking nuts at both ends of the bolts to clamp the soundproof cover between the upper and lower clamping plates. The inner sides of both the upper and lower clamping plates are equipped with anti-slip pads with wavy grooves, increasing the friction between the soundproof cover and the clamp, thus effectively preventing the soundproof cover from sliding or loosening during use.

[0034] Subsequently, the height of the soundproof enclosure is adjusted according to actual needs. The operator rotates handwheel 13, causing threaded rod 12 to rotate. Threaded rod 12 is threadedly connected to lifting block 4, thereby causing lifting block 4 to move up and down along sliding groove 3. Lifting block 4 is hinged to adjusting plate 5 via first connecting rod. When lifting block 4 moves, adjusting plate 5 rises and falls synchronously, thereby driving the fixing clamp 6 and the soundproof enclosure it holds to adjust its height. By observing the scale marks on the outside of threaded rod 12, the movement distance of lifting block 4 can be precisely controlled to ensure that the height of the soundproof enclosure meets design requirements.

[0035] If the angle of the soundproof enclosure needs to be adjusted, manually rotate the fixing clamp 6 to make it rotate around the rotating shaft 7. The rotating shaft 7 passes through the fixing clamp 6 and is rotatably connected to the adjusting plate 5 via a bearing. The limiting plate 8 is fixed to one end of the rotating shaft 7. As the fixing clamp 6 rotates, the limiting plate 8 also rotates. When the soundproof enclosure reaches the desired angle, the relative position between the limiting plate 8 and the adjusting plate 5 is locked by the locking assembly 9. The pin in the locking assembly 9 moves towards the limiting plate 8 under the action of the return spring, and the pin inserts into the limiting hole of the limiting plate 8, thereby achieving precise angle locking.

[0036] Throughout the adjustment process, the elastic element 14 plays an important buffering role. When the adjusting plate 5 moves up and down with the lifting block 4, the compression spring in the elastic element 14 extends and retracts accordingly. The protective sleeve on its outer side is filled with lubricant, which reduces the frictional loss of the spring during the extension and retraction process, and at the same time provides appropriate rebound force to prevent the device from becoming loose or unstable due to external vibration.

[0037] Furthermore, the design of the reinforcing ribs further improves the stability of the overall structure. The reinforcing ribs have a triangular cross-section, with both ends welded to the support frame 2 and the base 1, respectively. This design enhances the device's resistance to deformation, ensuring that it is not prone to tipping over or being damaged under complex working conditions.

[0038] Through the above steps, this invention achieves dual adjustment functions for the height and angle of the soundproof enclosure. It requires no additional power source, is easy to operate, and is inexpensive, significantly improving the flexibility and efficiency of soundproof enclosure installation and meeting the needs of different scenarios.

[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
