Description

Technical Field

[0001] This application belongs to the field of construction, and particularly relates to a new type of anti-collision buffer fence. Background Art

[0002] The guardrail is mainly used in construction sites to isolate and protect people's safety. Guardrails can be seen everywhere in our lives. Different application scenarios have different design shapes and layout methods to play different roles. Safety guardrails also need to be set up at construction sites. However, due to the extremely complex situation at the construction site, there are various types of vehicles, and there is a situation of mixing people and vehicles. Ordinary guardrails cannot be applied to the situation at the construction site and cannot effectively protect construction workers and construction vehicles. After the existing guardrails are installed, they are usually in a vertical state. When a construction vehicle hits the guardrail at high speed, the guardrail directly hits the vehicle head-on, resulting in vehicle damage or even casualties. And the height of the guardrail cannot be adjusted after installation. When a vehicle loaded with large equipment needs to pass above the guardrail, the guardrail may affect the passage of the vehicle, and the construction workers need to remove the guardrail, which is very inconvenient to operate. Summary of the Invention

[0003] This application provides a new type of anti-collision buffer fence to solve at least one of the above technical problems.

[0004] The technical solution adopted by this application is as follows:

[0005] A new type of anti-collision buffer fence includes a base fixed to the ground, a guardrail hinged above the base, and a telescopic column supporting the guardrail. One end of the telescopic column is hinged to the guardrail, and the other end is fixed to the ground. A speed radar is provided on the side of the guardrail facing outward. The anti-collision buffer fence further includes a control device communicatively connected between the speed radar and the telescopic column. The control device can control the telescopic column to expand and contract according to the speed of the object detected by the speed radar on the outside, so as to drive the guardrail to flip and tilt.

[0006] The new type of anti-collision buffer fence in this application also has the following additional technical features:

[0007] The control device presets a first speed threshold and a second speed threshold. When the speed radar detects that the speed of the object on the outside does not reach the first speed threshold, the control device controls the telescopic column to shorten by a first distance, so that the guardrail flips by a first angle; when the speed radar detects that the object on the outside is greater than the first speed threshold and less than the second speed threshold, the control device controls the telescopic column to shorten by a second distance, so that the guardrail flips by a second angle; when the speed radar detects that the object on the outside is greater than the second speed threshold, the control device controls the telescopic column to shorten by a third distance, so that the guardrail flips by a third angle.

[0008] The control device can also control the telescopic column to extend and retract to the initial state.

[0009] The telescopic column is also provided with a pressure detection device communicatively connected to the control device. The pressure detection device can detect the real-time pressure borne by the telescopic column and transmit the detected data to the control device. When the pressure detection device detects that the pressure borne by the telescopic column is higher than the initial pressure, the control device controls the position of the telescopic column to remain unchanged. When the pressure detection device detects that the pressure borne by the telescopic column drops to the initial pressure, the control device controls the telescopic column to extend, so that the guardrail flips to the initial state.

[0010] The guardrail includes a bracket hinged to the base and a shaft rod fixedly connected to the bracket and arranged horizontally, and a buffer barrel is arranged on the shaft rod.

[0011] The buffer barrel includes an inner barrel and an outer barrel sleeved outside the inner barrel. A buffer liquid is arranged in the inner barrel, and a buffer layer is filled between the outer barrel and the inner barrel.

[0012] The guardrail includes a fixing plate hinged to the base and the telescopic column, and a buffer plate fixed to the outside of the fixing plate.

[0013] A buffer spring is further arranged between the fixing plate and the buffer plate.

[0014] The anti-collision buffer rail further includes a guide plate located at the bottom end of the guardrail and extending outwards, and the height of the guide plate gradually decreases from the side wall of the guardrail outwards.

[0015] The anti-collision buffer plate is also provided with a reflective strip and an alarm.

[0016] Due to the adoption of the above technical solutions, the beneficial effects obtained by this application are as follows:

[0017] 1. In this application, the anti-collision buffer rail is set as a base fixed to the ground, a guardrail hinged above the base, and a telescopic column supporting the guardrail. One end of the telescopic column is hinged to the guardrail, and the other end is fixed to the ground. The telescopic column is used to support and limit the guardrail, improving the stability of the guardrail and avoiding the situation that the guardrail is prone to tipping due to unstable connection with the ground. At the same time, the user can adjust the telescopic column to a suitable height according to needs, and then adjust the guardrail to a suitable angle, making it applicable to different application scenarios, improving the applicability of the anti-collision buffer rail, and meeting different usage requirements of users.

[0018] Meanwhile, a speed measurement radar is provided on the outer side of the guardrail facing outward. The anti-collision buffer guardrail further includes a control device communicatively connected between the speed measurement radar and the telescopic column. The control device can control the telescopic column to expand and contract according to the speed of the object detected by the speed measurement radar on the outer side, so as to drive the guardrail to flip and tilt. When the guardrail is in the initial state, that is, in the vertical state, if there is an object approaching the guardrail at high speed (such as a car, etc.), after the speed measurement radar detects it, the speed measurement radar transmits the detected data to the control device. The control device compares the measured value with a preset threshold. If it is determined that the speed of the object approaching the guardrail is relatively high, the control device will control the telescopic column to contract, so that the guardrail flips and tilts around the ground hinge position. When the object impacts the guardrail, the inclination of the guardrail will cause the object to move obliquely upward, generating an upward component force, greatly reducing the horizontal force when the high-speed object impacts the guardrail, thereby reducing the collision intensity between the high-speed object and the guardrail, avoiding the situation where the high-speed object directly impacts the guardrail in the vertical state, resulting in injuries to personnel and damage to the guardrail due to high-speed impact between the object (such as a car, etc.) and the guardrail, reducing the probability of personnel injury, and at the same time avoiding the situation where the guardrail is severely deformed or even damaged, protecting the safety of personnel, extending the service life of the guardrail, and improving the user experience.

[0019] 2. As a preferred embodiment of the present application, a first speed threshold and a second speed threshold are preset in the control device. When the speed measurement radar detects that the speed of the object on the outer side does not reach the first speed threshold, the control device controls the telescopic column to shorten by a first distance, so that the guardrail flips by a first angle; when the speed measurement radar detects that the object on the outer side is greater than the first speed threshold and less than the second speed threshold, the control device controls the telescopic column to shorten by a second distance, so that the guardrail flips by a second angle; when the speed measurement radar detects that the object on the outer side is greater than the second speed threshold, the control device controls the telescopic column to shorten by a third distance, so that the guardrail flips by a third angle. That is, the control device will compare the detected speed value with the preset first speed threshold and second speed threshold. When the speed measurement radar detects that the speed of the object approaching the guardrail is higher, the control device will control the telescopic column to shorten a greater distance, so that the flipping angle of the guardrail is larger and the inclination angle of the guardrail is larger, thereby further reducing the impact force when the object impacts the guardrail, improving the anti-collision buffer effect of the guardrail, and at the same time reducing the damage degree of the object and the guardrail.

[0020] 3. As a preferred embodiment of the present application, the control device is set to be further capable of controlling the telescopic column to expand and contract to the initial state, so that the guardrail can return to the initial state, that is, the vertical state, by means of the elongation of the telescopic column after flipping, eliminating the operation of manually resetting the guardrail, reducing the labor intensity of the user, and improving the user experience.

[0021] 4. As a preferred embodiment of the present application, a pressure detection device is provided on the telescopic column and is communicatively connected to the control device, so that the pressure detection device can detect the real-time pressure borne by the telescopic column and transmit the detected data to the control device, and when the pressure detection device detects that the pressure borne by the telescopic column is higher than the initial pressure, the control device controls the position of the telescopic column to remain unchanged, and when the pressure detection device detects that the pressure borne by the telescopic column drops to the initial pressure, the control device controls the telescopic column to extend so that the guardrail flips to the initial state, that is, when a high-speed object collides with the guardrail, the object may stay On the guardrail, the pressure of the guardrail on the telescopic column is higher than that in the initial state. When the pressure detection device detects that the pressure is higher than the initial state, the control device will control the position of the telescopic column to remain unchanged to prevent the guardrail from flipping over when the object stays on the guardrail, causing relative displacement of the object and the guardrail, and ultimately causing secondary damage to the object; at the same time, when the personnel separate the object from the guardrail, the pressure of the guardrail on the telescopic column drops to the initial pressure. At this time, the control device can control the extension of the telescopic column to flip the guardrail to the initial state. The degree of automation is high, which eliminates the step of manually resetting the control device, further improving the user experience.

[0022] 5. As a preferred embodiment of the present application, the guardrail is configured to include a bracket hinged to the base and a shaft connected to the bracket and arranged transversely, and a buffer bucket is provided on the shaft, so that when a high-speed object collides with the guardrail, the high-speed object can reduce the relative impact force between the object and the guardrail with the help of the buffering effect of the buffer bucket, further improving the anti-collision buffering effect. At the same time, the buffer bucket is arranged transversely, so that when the object collides with the buffer bucket, it can move obliquely upward along the buffer bucket, further reducing the impact force of the direct collision between the object and the guardrail.

[0023] 6. As a preferred embodiment of the present application, the buffer barrel is configured to include an inner barrel and an outer barrel mounted outside the inner barrel, a buffer solution is provided in the inner barrel, and a buffer layer is filled between the outer barrel and the inner barrel. On the one hand, the buffer solution can improve the buffering performance of the buffer barrel and reduce the impact force when a high-speed object collides with the buffer barrel; on the other hand, the buffer layer between the outer barrel and the inner barrel can not only improve the buffering capacity, but also protect the inner barrel, thereby avoiding the situation where the buffer barrel is damaged after a high-speed object collides with the buffer barrel, thereby extending the service life of the buffer barrel.

[0035] As Figure 1 As shown, this application provides a new type of anti-collision buffer fence, including a base 1 fixed to the ground surface, a guardrail 2 hinged above the base 1, and a telescopic column 3 supporting the guardrail 2. One end of the telescopic column 3 is hinged to the guardrail 2, and the other end is fixed to the ground surface. A speed measurement radar 4 is provided on the side of the guardrail 2 facing the outside. The anti-collision buffer fence further includes a control device 5 communicatively connected between the speed measurement radar 4 and the telescopic column 3. The control device 5 can control the telescopic column 3 to expand and contract according to the speed of the object detected by the speed measurement radar 4 on the outside, so as to drive the guardrail 2 to flip and tilt.

[0036] In this application, the anti-collision buffer fence is set as a base 1 fixed to the ground surface, a guardrail 2 hinged above the base 1, and a telescopic column 3 supporting the guardrail 2. One end of the telescopic column 3 is hinged to the guardrail 2, and the other end is fixed to the ground surface. The telescopic column 3 is used to support and limit the guardrail 2, improving the stability of the guardrail 2 and avoiding the situation that the guardrail 2 is prone to tipping due to unstable connection with the ground surface. At the same time, the user can adjust the telescopic column 3 to a suitable height according to needs, and then adjust the guardrail 2 to a suitable angle, making it applicable to different application scenarios, improving the applicability of the anti-collision buffer fence, and meeting different usage requirements of users.

[0037] Meanwhile, a speed radar 4 is provided on the outer side of the guardrail 2 facing outward. The anti-collision buffer guardrail further includes a control device 5 communicatively connected between the speed radar 4 and the telescopic column 3. The control device 5 can control the telescopic column 3 to expand and contract according to the speed of the object detected by the speed radar 4 on the outer side, so as to drive the guardrail 2 to flip and incline. When the guardrail 2 is in the initial state, that is, in the vertical state, if there is an object approaching the guardrail 2 at high speed (such as a car, etc.), after the speed radar 4 detects it, the speed radar 4 transmits the detected data to the control device 5. The control device 5 compares the measured value with a preset threshold. If it is determined that the speed of the object approaching the guardrail 2 is relatively high, the control device 5 will control the telescopic column 3 to contract, so that the guardrail 2 flips and inclines around the ground hinge position. When the object impacts the guardrail 2, the inclination of the guardrail 2 will cause the object to move obliquely upward, generating an upward component force on the object, greatly reducing the horizontal force when the high-speed object impacts the guardrail 2, thereby reducing the collision intensity between the high-speed object and the guardrail 2, avoiding the situation where the high-speed object directly impacts the guardrail 2 when the guardrail 2 is in the vertical state, resulting in injuries to personnel and damage to the guardrail 2 due to high-speed impact between the object (such as a car, etc.) and the guardrail 2, reducing the probability of personnel injuries, and at the same time can also avoid the situation where the guardrail 2 is severely deformed or even damaged, protecting the safety of personnel, extending the service life of the guardrail 2, and improving the user experience.

[0038] As a preferred embodiment of the present application, the control device 5 is preset with a first speed threshold and a second speed threshold. When the speed radar 4 detects that the speed of the outer object does not reach the first speed threshold, the control device 5 controls the telescopic column 3 to shorten by a first distance, so that the guardrail 2 flips by a first angle; when the speed radar 4 detects that the outer object is greater than the first speed threshold and less than the second speed threshold, the control device 5 controls the telescopic column 3 to shorten by a second distance, so that the guardrail 2 flips by a second angle; when the speed radar 4 detects that the outer object is greater than the second speed threshold, the control device 5 controls the telescopic column 3 to shorten by a third distance, so that the guardrail 2 flips by a third angle.

[0039] By presetting a first speed threshold and a second speed threshold in the control device 5, and when the speed measuring radar 4 detects that the speed of the outer object does not reach the first speed threshold, the control device 5 controls the telescopic column 3 to shorten by a first distance, so that the guardrail 2 flips by a first angle; when the speed measuring radar 4 detects that the outer object is greater than the first speed threshold and less than the second speed threshold, the control device 5 controls the telescopic column 3 to shorten by a second distance, so that the guardrail 2 flips by a second angle; when the speed measuring radar 4 detects that the outer object is greater than the second speed threshold, the control device 5 controls the telescopic column 3 to shorten by a third distance, so that the guardrail 2 flips by a third angle. That is, the control device 5 will compare the detected speed value with the preset first speed threshold and second speed threshold. When the speed measuring radar 4 detects that the speed of the object approaching the guardrail 2 is higher, the control device 5 will control the telescopic column 3 to shorten a greater distance, so that the flipping angle of the guardrail 2 is larger, and the inclination angle of the guardrail 2 is larger, thereby further reducing the impact force when the object collides with the guardrail 2, improving the anti-collision buffering effect of the guardrail 2, and at the same time reducing the damage degree of the object and the guardrail 2.

[0040] It should be noted that the present application does not specifically limit the first speed threshold and the second speed threshold. As a preference of the present application, the first speed threshold is preferably 45 km / h. At the same time, the present application does not specifically limit the first angle, the second angle and the third angle. As a preference of the present application, the first angle is preferably 65°, the second angle is preferably 50°, and the third angle is preferably 40°.

[0041] As a preferred embodiment of the present application, the control device 5 can also control the telescopic column 3 to extend and retract to the initial state.

[0042] By setting the control device 5 to be able to control the telescopic column 3 to extend and retract to the initial state, the guardrail 2 can be restored to the initial state, that is, the vertical state, by the elongation of the telescopic column 3 after flipping, eliminating the need for manual reset of the guardrail 2, reducing the labor intensity of the user, and improving the user experience.

[0043] It should be noted that the present application does not specifically limit how the control device 5 controls the telescopic column 3 to expand and contract. It can be realized by manually controlling the control device 5 to achieve the expansion and contraction of the telescopic column 3. As a preferred embodiment of the present application, the telescopic column 3 is further provided with a pressure detection device communicatively connected to the control device 5. The pressure detection device can detect the real-time pressure borne by the telescopic column 3 and transmit the detected data to the control device 5. When the pressure detection device detects that the pressure borne by the telescopic column 3 is higher than the initial pressure, the control device 5 controls the position of the telescopic column 3 to remain unchanged. When the pressure detection device detects that the pressure borne by the telescopic column 3 drops to the initial pressure, the control device 5 controls the telescopic column 3 to extend so that the guardrail 2 flips to the initial state.

[0044] By providing a pressure detection device on the telescopic column 3 that is communicatively connected to the control device 5, the pressure detection device can detect the real-time pressure borne by the telescopic column 3 and transmit the detected data to the control device 5. When the pressure detection device detects that the pressure borne by the telescopic column 3 is higher than the initial pressure, the control device 5 controls the position of the telescopic column 3 to remain unchanged. When the pressure detection device detects that the pressure borne by the telescopic column 3 drops to the initial pressure, the control device 5 controls the telescopic column 3 to extend so that the guardrail 2 flips to the initial state. That is, when a high-speed object impacts the guardrail 2, the object may stay on the guardrail 2. Therefore, the pressure of the guardrail 2 on the telescopic column 3 is higher than that in the initial state. When the pressure detection device detects a pressure higher than the initial state pressure, the control device 5 will control the position of the telescopic column 3 to remain unchanged, avoiding the situation where when the object stays on the guardrail 2, the telescopic column 3 moves and causes the guardrail 2 to flip, resulting in relative displacement between the object and the guardrail 2 and ultimately causing secondary damage to the object. At the same time, when the person separates the object from the guardrail 2, the pressure of the guardrail 2 on the telescopic column 3 drops to the initial pressure. At this time, the control device 5 can control the telescopic column 3 to extend so that the guardrail 2 flips to the initial state, with a relatively high degree of automation, eliminating the step of manually controlling the control device 5 to reset and further improving the user experience.

[0045] It should be noted that the present application does not specifically limit the structure of the guardrail 2, and it can be any one of the following embodiments:

[0046] Embodiment 1: As Figure 2 shown, in this embodiment, the guardrail 2 includes a bracket 21 hinged to the base 1 and a shaft rod 22 fixedly connected to the bracket 21 and arranged horizontally, and a buffer barrel 7 is provided on the shaft rod 22.

[0047] By configuring the guardrail 2 to include a bracket 21 hinged to the base 1 and a shaft 22 fixedly connected to the bracket 21 and arranged transversely, and a buffer barrel 7 is arranged on the shaft 22, when a high-speed object collides with the guardrail 2, the high-speed object can reduce the relative impact force between the object and the guardrail 2 by means of the buffering effect of the buffer barrel 7, further improving the anti-collision buffering effect. At the same time, the buffer barrel 7 is arranged transversely, so that when the object collides with the buffer barrel 7, it can move obliquely upward along the buffer barrel 7, further reducing the impact force of the object directly colliding with the guardrail 2.

[0048] Furthermore, the buffer barrel 7 includes an inner barrel and an outer barrel mounted outside the inner barrel, a buffer solution is arranged in the inner barrel, and a buffer layer is filled between the outer barrel and the inner barrel.

[0049] By configuring the buffer barrel 7 to include an inner barrel and an outer barrel mounted outside the inner barrel, a buffer is provided in the inner barrel, and a buffer layer is filled between the outer barrel and the inner barrel. On the one hand, the buffer can improve the buffering performance of the buffer barrel 7 and reduce the impact force when a high-speed object collides with the buffer barrel 7; on the other hand, the buffer layer between the outer barrel and the inner barrel can not only improve the buffering capacity, but also protect the inner barrel, thereby avoiding the situation where the buffer barrel 7 is damaged after the high-speed object collides with the buffer barrel 7, thereby extending the service life of the buffer barrel 7.

[0050] Example 2: Figure 3 As shown, in this embodiment, the guardrail 2 includes a fixing plate 23 hinged to the base 1 and the telescopic column 3 and a buffer plate 24 fixed to the outer side of the fixing plate 23 .

[0051] By configuring the guardrail 2 to include a fixed plate 23 hinged to the base 1 and the telescopic column 3 and a buffer plate 24 fixed to the outside of the fixed plate 23, the fixed plate 23 can improve the overall strength of the guardrail 2 and improve the impact resistance of the guardrail 2. At the same time, the buffer plate 24 can improve the buffering performance of the guardrail 2, further reduce the impact force when the guardrail 2 collides with a high-speed object, and protect the guardrail 2 and the high-speed object.

[0052] Furthermore, if Figure 3 As shown, a buffer spring 8 is further provided between the fixing plate 23 and the buffer plate 24 .

[0053] By arranging the buffer spring 8 between the fixing plate 23 and the buffer plate 24, after the high-speed object hits the buffer plate 24, the force on the buffer plate 24 is transmitted to the buffer spring 8, thereby further improving the buffering effect and reducing the force between the buffer plate 24 and the high-speed object.

[0054] As a preferred implementation of the present application, Figure 1As shown, the anti-collision buffer rail further includes a guide plate 6 located at the bottom end of the guardrail 2 and extending outward, and the height of the guide plate 6 gradually decreases from the side wall of the guardrail 2 outward.

[0055] By providing a guide plate 6 extending outward at the bottom end of the guardrail 2, and the height of the guide plate 6 gradually decreasing from the side wall of the guardrail 2 outward, when a high-speed object impacts the guardrail 2, it moves upward under the guiding action of the guide plate 6, and generates an upward component force under the inclined guiding action of the guardrail 2, avoiding direct impact with the guardrail 2 and further improving the buffering effect of the guardrail 2.

[0056] As a preferred embodiment of the present application, the anti-collision buffer rail is further provided with a reflective strip and an alarm.

[0057] By providing a reflective strip and an alarm on the anti-collision buffer rail, the recognition rate of the anti-collision buffer rail is improved, which plays a warning role and reduces the risk of hitting the guardrail 2.

[0058] What is not described in this application can be realized by adopting or referring to the existing technology.

[0059] Each embodiment in this specification is described in a progressive manner. For the same or similar parts among the embodiments, reference can be made to each other. Each embodiment focuses on the differences from other embodiments.

[0060] The above are only the embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
