Description

Technical Field

[0001] The present invention relates to the technical field of construction fences, and more specifically, it relates to a highway construction protection device. Background Art

[0002] During construction, it is necessary to ensure the safe separation and effective warning between the construction area and the passing area. Fences are used as construction protection devices during construction. A fence refers to a measure taken to isolate the construction site from the external environment, making the construction site a relatively enclosed space; during highway construction, it is usually necessary to set up temporary protection devices near the construction site to protect the safety around the highway construction. At present, most of the widely used construction protection devices adopt a rigid structure design, which can play a basic role in isolation and warning. However, once an accident such as a vehicle impact occurs, its rigid characteristics will expose significant defects.

[0003] When a vehicle accidentally impacts a rigid protection device, due to its lack of sufficient buffering and deformation ability, the huge impact force is extremely likely to cause the protection device to be instantly damaged. Usually, it is manifested as the fence breaking, toppling, and the support structure being distorted. More seriously, after being damaged by the impact, the warning signs will lose their original warning effect along with the damage of the device.

[0004] Specifically, the broken or toppled guardrail cannot continue to remind the driver of the existence of the construction area in a complete form, making it difficult for the driver to detect the danger in time; moreover, the damaged warning signs cannot attract the driver's attention from a long distance, preventing them from taking measures such as decelerating and avoiding in advance, greatly increasing the risk of accidents. Summary of the Invention

[0005] The present invention provides a highway construction protection device to solve the technical problem that when a vehicle accidentally impacts a rigid protection device in the related art, the huge impact force is extremely likely to cause the protection device to be instantly damaged, and after being damaged by the impact, the warning signs will lose their original warning effect.

[0006] The present invention provides a highway construction protection device, including a base. Symmetric connecting seats are provided on the base, and fence columns are connected to the connecting seats through a locking mechanism. A deformable fence is provided on the side of the fence columns close to each other. Among them, the deformable fence includes fence boards arranged on the fence columns, and multiple fence straps are arranged between the two groups of fence boards. The multiple fence straps form a multi-level protection structure between the two groups of fence boards, increasing the coverage area of the protection. First connecting rods and second connecting rods are provided on both groups of fence boards. A connecting shaft is connected to the fence column through a bearing, and the connecting shaft is fixedly connected to the fence board.

One end of the first spring is fixedly connected to the collar, and the other end of the first spring is fixedly connected to the connecting seat.

[0011] As a further optimized solution of the present invention, a temporary warning unit is further provided on the base. The temporary warning unit includes an airbag bag arranged on the base, and multiple airbag columns are connected to the airbag bag. A connecting channel is opened inside the base, and both ends of the connecting channel are respectively communicated with the inside of the connecting seat.

[0012] As a further optimization solution of the present invention, a multi-component flow pipe is installed on the connection channel, and the flow pipe is communicated with the airbag bag and the airbag column. An air cavity is formed inside the connection seat, and the air cavity is communicated with the connection channel. A connection port is installed on the connection seat.

[0013] As a further optimization solution of the present invention, a protection plate is installed between the two fence columns, and the protection plate is used to protect the airbag bag and the airbag column.

[0014] As a further optimization solution of the present invention, a connection disk is installed inside the air cavity, and a warning airbag is installed on the connection disk. A through groove is formed inside the plug block, so that the warning airbag can pass through the through groove.

Specific embodiments

[0028] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein. Without departing from the scope of protection of the content of this specification, changes can be made to the functions and arrangements of the elements discussed. Each example can omit, substitute, or add various processes or components as needed. Additionally, the features described relative to some examples can also be combined in other examples.

[0029] According to the attached Figure 1 to the attached Figure 5 As shown, a highway construction protection device includes a base 11, symmetrically arranged connecting seats 12 on the base 11, and fence posts 13 are connected to the connecting seats 12 through a locking mechanism. A deformable fence is provided on the side of the fence posts 13 close to each other. Among them, the deformable fence includes fence panels 14 arranged on the fence posts 13, and multiple fence straps 15 are provided between the two groups of fence panels 14.

[0030] In specific implementation, the fence straps 15 can play a better warning role visually, reminding passing vehicles and pedestrians to pay attention to the construction area. The fence panels 14 and the fence straps 15 can usually be in eye-catching colors, such as yellow, orange, etc., which can attract the attention of drivers from a long distance, so as to make preparations for deceleration, avoidance, etc. in advance, and reduce the probability of traffic accidents.

[0031] Specifically, on the side where the two groups of fence panels 14 are close to each other, a first connecting rod 16 is installed. Inside the two groups of fence panels 14, a second connecting rod 17 is provided. On the side where the two groups of fence columns 13 are close to each other, a connecting shaft 18 is rotatably connected by bearings. The connecting shaft 18 is fixedly connected to the fence panel 14. A plurality of discs 19 are rotatably connected by bearings on the first connecting rod 16, and the number of discs 19 is the same as the number of fence straps 15. Both ends of the fence strap 15 pass through the second connecting rod 17 and are fixedly connected to the discs 19 on the two first connecting rods 16.

[0032] In this embodiment, multiple groups of fence straps 15 form a multi-level protection structure between the two groups of fence panels 14, increasing the coverage area of protection. It can not only block larger objects, but also effectively intercept some flying small fragments, sundries, etc., further improving the protection performance of the protection device.

[0033] Moreover, the fence strap 15 is made of a flexible strip material, which can buffer the impact object while avoiding unnecessary damage and improving the protection. At the same time, through the setting of the connecting shaft 18, when the fence panel 14 is impacted, under the action of the connecting shaft 18, the fence panel 14 can be driven to rotate to buffer the impact object.

[0034] Specifically, when a vehicle or other object impacts the fence panel 14, the fence panel 14 can rotate around the connecting shaft 18. This rotation can change the direction and action mode of the impact force, dispersing the originally concentrated impact force. Compared with the rigidly fixed fence panel 14, the rotating fence panel 14 can withstand a greater impact force without being easily damaged, extending the service life of the fence panel 14 and reducing the maintenance and replacement costs of the protection device.

[0035] It should be noted that the rotating fence panel 14 can play a certain buffering role on the impact object, reducing the impact force received by the impact object. For a vehicle, the buffering can reduce the damage degree of the vehicle and the risk of injury to the people in the vehicle; for other objects, it can also avoid breakage or splashing caused by a violent impact and prevent the occurrence of secondary injuries.

[0036] In addition, after buffering the impact, the rotatable fence panel 14 can quickly return to a relatively normal position and will not lie down on the road in a large area due to the impact, thus ensuring the basic traffic conditions of the road, helping to maintain traffic order, and reducing traffic congestion caused by accidents.

[0037] In this embodiment, according to the attached Figure 3 to the attached Figure 6As shown, the fence panel 14 is fixedly connected to the first connecting rod 16, and multiple groups of first rollers 161 are connected to the first connecting rod 16 by bearings; the fence panel 14 is slidably connected to the second connecting rod 17, and multiple groups of second rollers 171 are connected to the second connecting rod 17 by bearings. When the fence strap 15 is impacted, the first rollers 161 and the second rollers 171 can absorb and buffer part of the impact force through their own rotation, playing a role in shock absorption, thereby reducing the impact on the fence panel 14 and the entire protection device and improving the impact resistance of the protection device.

[0038] Furthermore, according to the appendix Figure 6 As shown, sliding grooves 141 are provided on both the upper and lower sides inside the fence panel 14, and sliders 142 are slidably connected in the sliding grooves 141. The sliders 142 are fixedly connected to the second connecting rod 17. A second spring 143 is installed on one side of the slider 142 close to the fence column 13, and the end of the second spring 143 away from the slider 142 is fixedly connected to the sliding groove 141.

[0039] Among them, the second spring 143 can absorb and disperse the impact force, playing a role in buffering and shock absorption. This helps to reduce the damage to the fence panel 14 and the entire protection device, extend its service life, and at the same time reduce the reaction force of the impact on the vehicle and the occupants in the vehicle, ensuring traffic safety.

[0040] In different impact situations, the magnitude and direction of the impact force are different. The elastic characteristics of the second spring 143 enable the slider 142 to slide adaptively in the sliding groove 141 according to the magnitude of the impact force, thereby driving the second connecting rod 17 to move. Through adaptive adjustment, the fence strap 15 can better adapt to impacts of different intensities and always maintain a good protection effect. For example, when receiving a small impact, the stretching amount of the second spring 143 is small, and the fence strap 15 can still maintain a certain tension; when receiving a large impact, the stretching amount of the second spring 143 increases, providing a larger buffer space for the fence strap 15.

[0041] It should be noted that when the fence strap 15 is impacted by a large external force, the fence strap 15 drives the second connecting rod 17 to move, enabling the second connecting rod 17 to slide in the sliding groove 141 through the slider 142, so that the fence strap 15 can have a certain buffer space. At the same time, the elastic force of the second spring 143 can absorb part of the impact force and reduce the damage to the fence strap 15 and the fence panel 14. When the external force disappears, the second spring 143 will push the slider 142 and the second connecting rod 17 back to the initial position, enabling the protection device to quickly return to the normal protection state.

[0042] Specifically, the second connecting rod 17 drives the slider 142 to slide in the chute 141, stretching the second spring 143. The elastic force generated by the second spring 143 resists the external force, achieving the effects of buffering and shock absorption. When the external force disappears, the second spring 143 releases energy according to its own elastic potential energy, pushing the slider 142 and the second connecting rod 17 back to their original positions, realizing the automatic reset of the protection device.

[0043] In addition, according to the attached Figure 7 to the attached Figure 9 As shown, the locking mechanism includes a connecting groove 121 opened inside the connecting seat 12, and an insertion block 122 is installed inside the connecting groove 121. A notch adapted to the insertion block 122 is opened at one end of the fence post 13 close to the connecting seat 12. The insertion block 122 is snap-fitted with the notch. First locking grooves are opened on the connecting seat 12 and the insertion block 122, and a second locking groove is opened on the fence post 13. An insertion rod 124 is provided inside the first locking groove and the second locking groove. The insertion rod 124 passes through the first locking groove and the second locking groove to lock the fence post 13. A first spring 125 and a collar are provided on the insertion rod 124. The collar is connected to the insertion rod 124 by a bearing. One end of the first spring 125 is fixedly connected to the collar, and the other end of the first spring 125 is fixedly connected to the connecting seat 12.

[0044] It should be explained in detail that when installing the fence post 13, first snap the insertion block 122 into the notch of the fence post 13, and then insert the insertion rod 124 into the first locking groove and the second locking groove, connecting the fence post 13, the insertion block 122 and the connecting seat 12 into a whole. When it is necessary to disassemble the fence post 13, just pull out the insertion rod 124 from the locking groove, and the locking between the fence post 13 and the connecting seat 12 can be released, which is convenient for maintaining the protection device or replacing components.

[0045] Among them, through the action of the first spring 125, during long-term use, even if the insertion rod 124 is subjected to certain vibrations or external force interference, it can ensure that the insertion rod 124 is always tightly inserted into the locking groove, ensuring the firm and reliable connection between the fence post 13 and the connecting seat 12, and reducing the risk of the protection device failing due to loose connection.

[0046] When the insertion rod 124 is inserted into the first locking groove and the second locking groove, the first spring 125 is compressed, generating elastic potential energy, thereby applying an elastic force towards the inside of the first locking groove and the second locking groove to the insertion rod 124, enabling the insertion rod 124 to be tightly stuck in the first locking groove and the second locking groove. When it is necessary to pull out the insertion rod 124, it is necessary to overcome the elastic force of the first spring 125 and pull out the insertion rod 124 from the first locking groove and the second locking groove. After the insertion rod 124 is pulled out, the first spring 125 will return to its initial state, preparing for the next locking operation.

[0047] According to the appended Figure 7 to the appended Figure 9 As shown, in this embodiment, a temporary warning unit is provided. The temporary warning unit is arranged on the base 11. The temporary warning unit includes an airbag 21 arranged on the base 11, and multiple airbag columns 22 are connected to the airbag 21. A connection channel 23 is opened inside the base 11, and both ends of the connection channel 23 are respectively communicated with the inside of the connection seat 12.

[0048] It should be understood that when the fence posts 13 and fence panels 14 are damaged due to being hit by a vehicle or other situations, resulting in the failure of the protection function, on-site workers can disassemble the fence posts 13 from the connection seats 12, so that the temporary warning unit can play a role in a timely manner. After the airbag 21 and multiple airbag columns 22 are inflated, they can form an obvious warning sign, attracting the attention of passing vehicles and pedestrians, reminding them that there is an abnormal situation ahead, playing a role of temporary warning, and reducing the possibility of accidents.

[0049] Among them, multiple flow-dividing pipes are installed on the connection channel 23, and the flow-dividing pipes are communicated with the airbag 21 and the airbag columns 22. An air chamber 24 is opened inside the connection seat 12, and the air chamber 24 is communicated with the connection channel 23. A connection port 25 is installed on the connection seat 12. In this embodiment, through the settings of the connection channel 23, the flow-dividing pipes, the air chamber 24 and the connection port 25, rapid inflation of the airbag 21, the airbag columns 22 and the warning airbag 27 can be realized, enabling the temporary warning unit to play a role in a short time, making a rapid response to emergencies, and improving the ability of the protection device to cope with accidents. In this embodiment, when in use, the connection port 25 is connected to an external air supply device, such as any one of a blower, a fan, an air pump and other devices, so as to facilitate the rapid inflation of the airbag 21, the airbag columns 22 and the warning airbag 27.

[0050] In other embodiments, according to the appended Figure 8 and the appended Figure 9 As shown, a connection disk 26 is installed inside the air chamber 24, and a warning airbag 27 is installed on the connection disk 26. A through groove 123 is opened inside the insertion block 122, so that the warning airbag 27 can pass through the through groove 123. During operation, the warning airbag 27 can pass through the through groove 123 of the insertion block 122, and can also provide a warning at the connection part between the fence post 13 and the connection seat 12, cooperating with the airbag 21 and the airbag columns 22, enhancing the comprehensiveness of the warning of the entire protection device, improving the integrity of the protection, and enabling the warning function to still be effectively exerted even if some structures are damaged.

[0051] It should be noted that pull rings are installed at the ends of the two sets of insertion rods 124 close to each other. Pulling the pull rings can disassemble the fence posts 13. The outer surface of the end of the insertion rod 124 away from the pull ring is provided with an external thread, and the inner wall of the first locking groove near the pull ring end is provided with an internal thread. When it is necessary to activate the temporary warning unit, the insertion rod 124 can be pulled out and fixed by screwing between the internal thread and the external thread, so that the warning airbag 27 can pass through the through groove 123, avoiding obstacles to the warning airbag 27.

[0052] Working principle: As shown in the appendix Figure 10 When the insertion rod 124 is pulled outwards, the insertion rod 124 moves axially along the center line of the first locking groove and the second locking groove. At this time, the first spring 125 undergoes elastic deformation. However, since the first spring 125 is fixedly connected to the connecting seat 12 and the collar, the insertion rod 124 is not restricted by the fixed relationship of the first spring 125 when being pulled out, and the insertion rod 124 can rotate within the collar.

[0053] That is to say, the insertion rod 124 can slide axially in the first locking groove and can also rotate within the collar. When the insertion rod 124 rotates, the external thread on the insertion rod 124 is threadedly connected to the internal thread on the first locking groove, so that the insertion rod 124 is fixed.

[0054] Furthermore, as shown in the appendix Figure 8 A protective plate 28 is provided on the base 11, and both ends of the protective plate 28 close to the fence post 13 are fixedly connected to the fence post 13. The protective plate 28 is installed between the two sets of fence posts 13 and is used to protect the airbag bag 21 and the airbag column 22. In this embodiment, the protective plate 28 is installed between the two sets of fence posts 13 and can protect the airbag bag 21 and the airbag column 22. When an object impacts the protection device, the protective plate 28 first bears the impact force, preventing the airbag bag 21 and the airbag column 22 from being directly impacted and damaged, extending the service life of the temporary warning unit and ensuring its normal operation when needed.

[0055] It should be noted that when it is necessary to activate the temporary warning unit, air can be inflated into the air chamber 24 through the connection port 25. After the gas enters the air chamber 24, a part of it flows through the connection channel 23 to the airbag bag 21, causing the airbag bag 21 to expand; another part flows through the shunt pipe to the airbag column 22, causing the airbag column 22 to stand up. At the same time, the gas in the air chamber 24 also causes the warning airbag 27 to expand and pass through the through groove 123 of the insertion block 122, forming a multi-directional warning structure.

[0056] The embodiments of the above specific implementation manners have been described, but the present embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of the present embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of the present embodiment.
