Description

TECHNICAL FIELD

[0001] The application relates to the technical field of road construction protection, in particular to a highway asphalt paving protection device. BACKGROUND

[0002] The asphalt pavement refers to various types of pavements constructed by mixing road asphalt materials into mineral materials. The asphalt binder improves the ability of the paving granules to resist the damage of vehicles and natural factors to the pavement, so that the pavement is flat, less dusty, water-proof and durable. Therefore, the asphalt pavement is a kind of senior pavement most widely used in road construction. The asphalt pavement is various types of pavements formed by paving and rolling asphalt concrete. The asphalt concrete is a mixture formed by fully mixing asphalt materials with certain viscosity and proper amount with mineral aggregates with certain gradation. The asphalt concrete as the asphalt pavement material needs to bear the repeated action of vehicle load and the long-term influence of environmental factors during use. Therefore, the asphalt concrete must have good durability to resist the action of natural factors while having certain bearing capacity. That is to say, the asphalt concrete must have sufficient stability in high-temperature environment, anti-cracking property in low-temperature condition, good water stability, long-term anti-aging property and anti-sliding property for safety, so as to ensure the good service function of the asphalt pavement. In order to prevent the influence of the external environment on the construction site during the construction of the asphalt pavement, the safety protection device needs to be used. The existing safety protection device is a protective fence. The existing protection device has many defects. For example, the existing protection device is generally an integral whole, needs to be transported to the construction site and then placed. The structure of the protection device is an integral structure, which occupies the transportation space and leads to the decrease of the transportation efficiency. In addition, if one component of the existing protection device is damaged, the entire protection device needs to be replaced, which increases the cost. In addition, in order to better protect the construction site and prevent the tools in the construction site from being stolen, the conical spikes are installed at the top of the protection device to prevent external personnel from climbing. However, the anti-theft conical spikes cannot be hidden and are easy to prick the workers during the installation and transportation.

[0003] The prior art document with the publication number CN113585873B provides a safety protection device for asphalt pavement construction. By pulling the insertion rod outward, the insertion rod is withdrawn from the insertion hole. Under the elastic force of the first spring, the spike protrudes from the opening, thereby effectively preventing external personnel from climbing the protective frame and providing more effective protection for the construction site. When the spike is recovered, the sliding plate is pressed downward, the sliding plate moves downward, and the insertion rod moves along the guide groove. When the insertion rod moves to the position of the insertion hole, the insertion rod is reinserted into the insertion hole under the action of the second spring, thereby hiding the spike in the cavity at the upper end of the protective frame. When assembling the entire device, the non-protruding spike can effectively prevent workers from being injured. The guide groove serves as a limiting function, allowing the insertion rod to be stably inserted into the insertion hole. The end of the insertion rod is arc-shaped, making the movement of the insertion rod in the guide groove smoother. The two sides of the sliding plate are fixedly connected with limiting blocks, which can slide in the limiting groove. The cooperation of the limiting groove and the limiting block ensures that the sliding plate and the fixed plate can stably slide in the cavity of the protective frame, allowing the spike to always align with the opening.

[0004] Although the above-mentioned prior art solution can achieve the beneficial effects related to the prior art, it still has the following defects: the device uses spikes for protection during use, which can cause injuries to climbers during protection. In addition, the protective device is placed outdoors for a long time and is prone to rust. Once a climber is injured, there is a risk of tetanus that can endanger life.

[0005] In view of this, we propose a highway asphalt paving protection device. Content of the utility model

DETAILED DESCRIPTION

[0028] The application is further described in detail below with reference to the accompanying drawings of the specification.

[0029] A highway asphalt paving protection device, comprising a support 1 and a guardrail 2 fixed on the support 1, the support 1 comprising two vertical rods 11, the vertical rod 11 being vertically provided with a mounting opening 111, a water spraying mechanism 4 being slidingly inserted into the mounting opening 111, the water spraying mechanism 4 being elastically connected with the vertical rod 11, the water spraying mechanism 4 comprising a piston rod 41, a water spraying pipe 43 and a plurality of water spraying holes 431 provided on the water spraying pipe 43, the piston rod 41 being slidingly inserted into the mounting opening 111, the water spraying pipe 43 being in communication with the mounting opening 111, a roller shaft 3 being rotatably provided between the two piston rods 41, and a rotating impact type warning mechanism 5 being mounted between the roller shaft 3 and the piston rod 41.

[0030] Reference Figures 1-5 The whole is placed on the protection side, and the water spraying holes 431 are directed outward. When a person wants to climb over, the roller shaft 3 will rotate to reduce the stability of the person, and when the roller shaft 3 rotates, the warning mechanism 5 rotates and impacts to emit a warning sound to warn the person. Finally, when the piston rod 41 is pressed downward, a sufficient amount of clean water is contained in the mounting opening 111. When the piston rod 41 is pressed downward, the water pressure in the mounting opening 111 increases, and then the water is sprayed to the person through the water spraying pipe 43 and the water spraying holes 431, so that the person can give up climbing over, and the whole will not cause unnecessary damage to the person.

[0031] The vertical rod 11 is provided on one side with a water injection hole 112 in communication with the mounting opening 111.

[0032] Reference Figure 3 The water injection hole 112 is used to facilitate water injection into the mounting opening 111, and after water injection, the lower end of the piston rod 41 is placed below the water injection hole 112 to avoid water overflow through the water injection hole 112 when pressurized.

[0033] The first spring 42 is fixed between the vertical rod 11 and the piston rod 41.

[0034] Reference Figure 2 The first spring 42 is elastically supported to support the piston rod 41, and when the piston rod 41 is pressed downward, the first spring 42 is elastically compressed, and after the piston rod 41 is not compressed, the roller shaft 3 and the piston rod 41 are reset.

[0035] The warning mechanism 5 comprises second springs 51, metal balls 52 and iron bells 53. The second springs 51 are annularly distributed at one end of the roller shaft 3, and each of the second springs 51 is fixed with a metal ball 52. The iron bells 53 are fixed within the rotating radius of the second springs 51, and the iron bells 53 are fixed on the piston rod 41.

[0036] Referring to Figure 1 and Figure 2 When the roller shaft 3 rotates, the second springs 51 will drive the metal balls 52 to rotate, and the iron bells 53 will produce a warning sound when the metal balls 52 hit the iron bells 53, thereby playing a warning role. The bending of the second springs 51 ensures the normal rotation of the roller shaft 3.

[0037] The water spraying pipe 43 is in a U-shaped structure, and the two ends of the water spraying pipe 43 are connected with the mounting ports 111 of the vertical rods 11 in a penetrating manner. The water spraying holes 431 are transversely distributed.

[0038] Referring to Figure 1 The two ends of the water spraying pipe 43 are connected with the mounting ports 111 of the two vertical rods 11 in a penetrating manner, so that the two ends of the water spraying pipe 43 can be watered. The transversely distributed water spraying holes 431 can increase the transverse coverage of water spraying.

[0039] Working principle: Add enough clean water into the mounting ports 111 through the water injection holes 112, and then place the whole device on the protection side, with the water spraying holes 431 facing outward. When the climber wants to climb over, the roller shaft 3 will rotate, reducing the stability of the climber. At the same time, the roller shaft 3 drives the second springs 51 and the metal balls 52 to rotate, and the iron bells 53 produce a warning sound when the metal balls 52 hit the iron bells 53, thereby playing a warning role. When the piston rod 41 is pressed downward, the water pressure in the mounting ports 111 increases, and then the water is sprayed to the climber through the water spraying pipe 43 and the water spraying holes 431, so that the climber can give up climbing.
