Description

Technical Field

[0001] This utility model relates to the field of shock-absorbing bracket technology, and in particular to a shock-absorbing bracket device for an air curtain machine. Background Technology

[0002] Permafrost is a special type of soil or rock with a temperature below 0°C and containing ice. Soil or rock that has remained frozen for two years or more is called permafrost. The physical properties of permafrost are greatly affected by external temperatures. Rising temperatures cause permafrost to thaw, lowering its upper limit and reducing the bearing capacity of permafrost foundations. Therefore, structures in permafrost regions often experience thaw settlement. In recent years, with the construction of black asphalt pavements in permafrost areas, the strong heat absorption and high heat accumulation effect of asphalt pavements has caused the underlying permafrost to continuously heat up. In addition, the high heat absorption of asphalt pavements hinders the evaporation and heat dissipation of moisture within the subgrade soil, inducing a downward shift in the upper limit of the underlying permafrost. This leads to increasingly serious problems such as roadbed instability and thermal thaw settlement in high-temperature, high-ice-content permafrost regions.

[0003] Existing permafrost protection measures mainly focus on reducing or preventing heat from entering the roadbed. Currently, air curtain units are installed on permafrost pavements to increase the air velocity above the asphalt surface layer, thereby achieving forced convection and efficient heat insulation of the air above the road surface. By reducing external heat conduction, the forced convection and heat exchange efficiency between the ground and the air are improved, thus lowering the ground temperature and protecting the stability of permafrost. However, the dynamic load of passing vehicles can easily cause vibration of the air curtain unit, affecting its stability. Utility Model Content

[0004] The purpose of this invention is to address the problem in the prior art that the dynamic load of passing vehicles on the road can easily cause vibration of the air curtain machine, affecting its stability, and to provide a shock-absorbing bracket device for the air curtain machine.

[0005] This utility model provides a shock-absorbing support device for an air curtain machine, including a base plate and a support, wherein the base plate is located above the support, and a shock absorber is provided between the base plate and the support;

[0006] It also includes a limiting mechanism located between the base plate and the bracket, the limiting mechanism being used to restrict the horizontal movement of the base plate relative to the bracket.

[0007] The shock-absorbing bracket device of this application includes a base plate and a bracket. The base plate is used to install the air curtain machine, and a shock absorber is provided between the base plate and the bracket. When the dynamic load of passing vehicles on the road acts on the base plate, the shock absorber dampens the vertical vibration of the base plate. Furthermore, a limiting mechanism is provided between the base plate and the bracket to restrict the horizontal movement of the base plate relative to the bracket, thereby preventing the dynamic load of passing vehicles on the road from causing horizontal displacement of the base plate. The shock-absorbing bracket device described in this application can effectively reduce the impact of the dynamic load of passing vehicles on the air curtain machine and improve the stability of the air curtain machine.

[0008] Preferably, the limiting mechanism includes a limiting plate and a limiting frame, wherein the limiting plate is connected to the side of the base plate near the bracket;

[0009] The limiting frame is located between the two limiting plates, and both sides of the limiting frame abut against the limiting plates. The limiting frame is connected to the bracket. A limiting plate is provided on the base support plate, and a limiting frame is provided on the bracket 2. The limiting frame is located between the two limiting plates. By ensuring that both sides of the limiting frame abut against the limiting plates, the limiting frame restricts the horizontal movement of the base support plate, thereby limiting the horizontal movement of the base support plate relative to the bracket.

[0010] Preferably, the vertical height of the limiting plate is H, and the interval between the base support plate and the bracket is L, where 0.8L < H < L. When the base support plate vibrates and moves downward, it will compress the shock absorber until the limiting plate abuts against the bracket, at which point the base support plate stops moving downward. The limiting plate prevents the base support plate from moving excessively downward, thus avoiding excessive compression of the shock absorber.

[0011] Preferably, the vertical height of the limiting frame is equal to the vertical height of the positioning plate. After the limiting plate abuts against the bracket, since the vertical height of the limiting frame is equal to the vertical height of the limiting plate, the limiting frame contacts the base support plate, providing a certain supporting effect to the base support plate through the limiting frame.

[0012] Preferably, the limiting plate is detachably connected to the base plate. This detachable connection facilitates the replacement of the limiting plate.

[0013] Preferably, the bracket includes a support plate and legs connected to each other, and the limiting frame is connected to the support plate. The bracket is fixed to the ground by the legs, and the support plate is used to support the base plate and the air curtain machine.

[0014] Preferably, the system further includes a strut connected to both ends of the support plate, and the strut forms an acute angle with the leg.

[0015] Preferably, the end of the strut near the support plate has a first hinge seat, and the first hinge seat is connected to the support plate;

[0016] The end of the strut away from the support plate has a second hinge seat, which is fixed to the ground.

[0017] Preferably, the shock absorber is a spring shock absorber.

[0018] Preferably, it also includes a protective cover hinged to the base plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] The shock-absorbing bracket device of this application includes a base plate and a bracket. The base plate is used to install the air curtain machine, and a shock absorber is provided between the base plate and the bracket. When the dynamic load of passing vehicles on the road acts on the base plate, the shock absorber dampens the vertical vibration of the base plate. Furthermore, a limiting mechanism is provided between the base plate and the bracket to restrict the horizontal movement of the base plate relative to the bracket, thereby preventing the dynamic load of passing vehicles on the road from causing horizontal displacement of the base plate. The shock-absorbing bracket device described in this application can effectively reduce the impact of the dynamic load of passing vehicles on the air curtain machine and improve the stability of the air curtain machine.

[0032] Example 1

[0033] like Figure 1 As shown, a shock-absorbing support device for an air curtain machine according to this embodiment includes a base plate 1, a support 2, a shock absorber 3, and a limiting mechanism 4. The base plate 1 and the support 2 are vertically spaced apart, with the base plate 1 located above the support 2. The shock absorber 3 and the limiting mechanism 4 are located between the base plate 1 and the support 2. The shock absorber 3 is used to vertically dampen the base plate 1, and the limiting mechanism 4 is used to limit the horizontal movement of the base plate 1 relative to the support.

[0034] When the dynamic load of passing vehicles on the road acts on the base plate 1, the shock absorber 3 dampens the base plate 1 to reduce the vertical vibration of the base plate 1. Furthermore, a limiting mechanism 4 is set between the base plate 1 and the bracket 2 to restrict the horizontal movement of the base plate 1 relative to the bracket 2, thereby preventing the dynamic load of passing vehicles on the road from causing horizontal displacement of the base plate 1. The shock-absorbing bracket device of this embodiment can effectively reduce the impact of the dynamic load of passing vehicles on the air curtain machine and improve the stability of the air curtain machine.

[0035] In one or more implementations, such as Figure 2 As shown, the limiting mechanism 4 includes a limiting plate 41 and a limiting frame 42. The limiting plate 41 is connected to the side of the base plate 1 near the bracket 2.

[0036] The limiting frame 42 is located between two limiting plates 41, and both sides of the limiting frame 42 abut against the limiting plates 41. The limiting frame 42 is connected to the bracket 2.

[0037] A limiting plate 41 is provided on the base plate 1, and a limiting frame 42 is provided on the bracket 2. The limiting frame 42 is located between the two limiting plates 41. By making both sides of the limiting frame 42 abut against the limiting plate 41, the limiting frame 42 restricts the horizontal movement of the base plate 1, thereby restricting the horizontal movement of the base plate 1 relative to the bracket 2.

[0038] In this embodiment, a limiting mechanism 4 includes two limiting plates 41 and a limiting frame 42. Each side of the limiting frame 42 abuts against a limiting plate 41, thereby forming a displacement limiter between the limiting plate 41 and the limiting frame 42 to limit the horizontal movement of the base support plate 1 relative to the bracket.

[0039] Among them, the limiting plate 41 is an L-shaped plate made of stainless steel; the limiting frame 42 is a frame structure made of stainless steel.

[0040] In this embodiment, the shock absorbers 3 are located at both ends of the bracket 2, and the base plate 1 is connected to the bracket 2 through the shock absorbers 3. Limiting mechanisms 4 are provided between the shock absorbers 3, and the number of limiting mechanisms 4 is not less than 2.

[0041] In optional implementations, such as Figure 2 As shown, the vertical height of the limiting plate 41 is H, and the interval between the base plate 1 and the bracket is L, where 0.8L < H < L.

[0042] When the base plate 1 vibrates and moves downward, the base plate 1 will compress the shock absorber 3 until the limit plate 41 abuts against the bracket 2 and the base plate 1 stops moving downward. The limit plate 41 prevents the base plate 1 from moving downward excessively and avoids excessive compression of the shock absorber 3.

[0043] In an optional implementation, the shock absorber 3 is preferably a spring shock absorber.

[0044] In an optional embodiment, the vertical height of the limiting frame 42 is equal to the vertical height of the limiting plate 41.

[0045] After the limiting plate 41 abuts against the bracket 2, since the vertical height of the limiting frame 42 is equal to the vertical height of the limiting plate 41, the limiting frame 42 contacts the base support plate 1 and provides a certain support to the base support plate 1 through the limiting frame 42.

[0046] In an optional embodiment, the limiting plate 41 is detachably connected to the base support plate 1, facilitating the replacement of the limiting plate 41.

[0047] In one or more implementations, such as Figure 3 As shown, the bracket 2 includes a support plate 21 and a support leg 22 that are connected to each other, and the limiting frame 42 is connected to the support plate 21.

[0048] The bracket 2 is fixed to the ground by the support legs 22, and the support plate 21 is used to support the base plate 1 and the air curtain machine 5.

[0049] The outrigger 22 includes a pre-embedded anchor rod 221, a first channel steel 222, and a V-shaped stiffener 223. One end of the pre-embedded anchor rod 221 is pre-embedded in the road surface, and the other end of the pre-embedded anchor rod 221 is connected to the support plate 21. The first channel steel 222 is fixed to the rod body of the pre-embedded anchor rod 221 by the V-shaped stiffener 223.

[0050] In an optional embodiment, a strut 23 is also included, which is connected to both ends of the support plate 21 and forms an acute angle with the support leg 22.

[0051] Among them, the end of the strut 23 near the support plate 21 has a first hinge seat 231, and the first hinge seat 231 is connected to the support plate 21;

[0052] The end of the strut 23 away from the support plate 21 has a second hinge seat 232, which is fixed to the ground. First, a pre-embedded bolt is set on the ground, and then the second hinge seat 232 is connected to the pre-embedded bolt.

[0053] The strut 23 includes a first hinge seat 231, a second hinge seat 232, and a second channel steel 233. The first hinge seat 231 and the second hinge seat 232 are both connected to the second channel steel 233 by bolts.

[0054] Example 2

[0055] like Figure 1 As shown in Embodiment 1, this embodiment of the shock-absorbing bracket device for an air curtain machine further includes a protective cover 6, which is hinged to the base plate 1. The protective cover 6 protects the air curtain machine 5, keeping its operating environment clean and dry, and preventing dust from passing vehicles or wind and snow accumulation from damaging the body of the air curtain machine 5.

[0056] The protective cover 6 is hinged to the base plate 1, allowing the protective cover 6 to be flipped relative to the base plate 1. When installing the air curtain machine 5, the protective cover 6 is first flipped open, then the air curtain machine 5 is fixed on the base plate 1, and then the protective cover 6 is flipped back so that the protective cover 6 covers the air curtain machine 5, thus protecting the air curtain machine 5.

[0057] In an optional embodiment, an air filter 7 is also included. The air filter 7 is installed at the air outlet of the air curtain machine 5. By setting the air filter 7, while ensuring that the air curtain machine 5 can exhaust air normally to the outside, dust or sand and snow from passing vehicles can be prevented from entering the air curtain machine 5.

[0058] 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.
