Description

Technical Field

[0001] The invention belongs to the technical field of construction guardrails, and in particular relates to a multifunctional and easily dismantled guardrail for road and bridge construction and a use method thereof. Background Art

[0002] The word "road" literally means the infrastructure for various trackless vehicles and pedestrians to pass through. According to their usage characteristics, they are divided into highways, urban roads, rural roads, factory and mining roads, forestry roads, examination roads, competition roads, automobile test roads, workshop passages and school roads, etc. There were also post roads in ancient China.

[0003] Bridges generally refer to structures erected over rivers, lakes, and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that are erected to cross mountain streams, poor geology, or meet other transportation needs to make travel more convenient. Bridges are generally composed of superstructures, substructures, supports, and ancillary structures. The superstructure, also known as the span structure, is the main structure for crossing obstacles; the substructure includes abutments, piers, and foundations; the supports are force transmission devices installed at the supporting locations of the span structure and piers or abutments; the ancillary structures refer to the bridgehead slabs, conical slope protection, revetments, diversion projects, etc.

[0004] Guardrails, also known as guardrails or fences, are safety facilities used to protect people, equipment or property from injury or loss. They are usually installed in balconies, windows, stairs, bridges, roads, construction sites and other places where there may be safety hazards.

[0005] The authorization publication number "CN110541361B" records "a road and bridge construction guardrail, belonging to the field of road administration facilities. The road and bridge construction guardrail includes: a pair of supporting base plates, a supporting connecting plate and a buffer protection mechanism. The pair of supporting base plates are connected by a protective plate, and one supporting base plate is located above the other supporting base plate; the supporting connecting plate is arranged on the rear end of the protective plate, and the supporting connecting plate can be fixed on the ground; the buffer protection mechanism is arranged on the front end of the protective plate. The road and bridge construction guardrail provided by the present invention has a buffer protection mechanism, so that the present invention can effectively protect the vehicle, ensure the personal safety of the people inside the vehicle, and extend the service life of the present invention."

[0006] The road and bridge construction guardrail provided by the above patent includes a buffer protection mechanism, which includes a first linkage component, a second linkage component and a buffer component. Therefore, when a vehicle collides with the present invention, the kinetic energy of the vehicle will be converted into the kinetic energy of the first linkage component, the second linkage component, and the elastic potential energy of the buffer component, so that the vehicle's driving speed can be slowed down and the vehicle can be stopped quickly, which can not only avoid serious damage to the vehicle and ensure the personal safety of the people inside the vehicle, but also extend the service life of the present invention. However, the existing guardrails are mostly installed by bolt fastening, which makes the installation and disassembly of the guardrail cumbersome. At the same time, the guardrail has a single function and cannot guide pedestrians and non-motor vehicles at night, which makes it easy for pedestrians to approach the guardrail and fail to avoid safety hazards for pedestrians and non-motor vehicles. At the same time, during dust reduction operations, it does not have the function of guiding pedestrians and non-motor vehicles to avoid, causing the dust reduction mist to block the line of sight of pedestrians and non-motor vehicles, which is very likely to cause collision safety hazards between pedestrians and non-motor vehicles. For this reason, we propose a multifunctional and detachable guardrail for road and bridge construction and a method for using it. Summary of the invention

[0023] A method for using a multifunctional detachable guardrail for road and bridge construction comprises the following steps:

[0024] S1. Seamless installation:

[0025] When docking and installing multiple guardrails, first, hoist and arrange multiple bases according to the actual site requirements, and then hoist multiple baffles and other attachment devices on the top of the base, so that multiple plug rods are inserted into multiple plug holes, and the baffle is located in the embedded groove, the threaded plug rod is inserted into the threaded hole and the multiple plug holes, and the threaded plug rod is threadedly installed in the threaded hole, and multiple infrared cameras are connected in parallel through power lines one by one so that the multiple infrared cameras are powered on and started. Each guardrail is powered on by the infrared camera to start the first electric push rod, and the output end of the first electric push rod pushes the slider to slide in the slide groove, and the slider drives the push-pull block to move, and the push-pull block pushes the push-pull rod, and the push-pull rod pushes the flap to deflect with two shaft sleeves as the fulcrum, so that the flap blocks the gap between the two baffles, avoiding the gap between the two baffles, so that the two baffles can be seamlessly installed;

[0026] S2, trigger start:

[0027] After the seamless installation of multiple guardrails, each infrared camera keeps each integrated terminal powered, and each integrated terminal detects the distance between pedestrians and non-motor vehicles and the guardrail in real time. When the distance between pedestrians and non-motor vehicles and the guardrail is less than the minimum distance, the infrared camera triggers the movement of the integrated terminal;

[0028] S3, sound and light warning:

[0029] When the distance between pedestrians and non-motor vehicles and the guardrail is less than the minimum distance, the swing program in the integrated terminal storage unit is started, and the output end of the second motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate by meshing with the driven gear. The driven gear drives the flip box to deflect in the flip groove through an extension shaft of the flip box, and then the gap drives the color laser to swing up and down. When the color laser needs to be positioned, the second electric push rod engages with the ratchet wheel in one direction by squeezing the pawl to lock the up and down swing of the color laser. When the color laser needs to swing left and right, the infrared camera is powered on to start the stepper. The output end of the motor drives the half gear to rotate, and the half gear drives the deflection shaft to rotate by meshing with the deflection gear. The deflection shaft drives the swing frame to swing slightly in the flip box, and the swing frame pushes the color laser to swing left and right in the arc groove. The color laser can move up and down and left and right, so that the laser emitted by the color laser can form different color luminous patterns on the ground. At the same time, the infrared camera has a built-in sounder to play warning words to the side end of the baffle to prevent pedestrians and non-motor vehicles from approaching the guardrail, avoid pedestrians and non-motor vehicles from approaching safety hazards, and realize sound and light warnings to pedestrians and non-motor vehicles;

[0030] S4. Water mist dust suppression:

[0031] Guardrails are usually installed outside the construction site. When dust reduction is required, multiple nozzles extract water from the on-site water tank and pressurize it, and spray it out from the top of the nozzles to form water mist. The sprayed water mist is used to reduce dust on the construction site, thus achieving water mist dust reduction.

[0032] S5. Avoidance guidance:

[0033] During the water mist dust reduction process, the adjustment mechanism moves the colored laser to illuminate the guidance route for pedestrians and non-motor vehicles on the ground, prevent pedestrians and non-motor vehicles from approaching the guardrails, guide pedestrians and non-motor vehicles to travel outside the dust reduction water mist, prevent the dust reduction water mist from blocking the line of sight of pedestrians and non-motor vehicles, prevent the safety hazard of collision between pedestrians and non-motor vehicles, and realize the avoidance guidance of pedestrians and non-motor vehicles.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. In this scheme, when multiple guardrails are docked and installed, multiple bases are first hoisted and arranged according to the actual site requirements, and then multiple baffles and other attachment devices are hoisted on the top of the base, so that multiple plug rods are inserted into multiple plug holes, and the baffles are located in the embedded grooves, the threaded plug rods are inserted into the threaded holes and multiple plug holes, and the threaded plug rods are threadedly installed in the threaded holes, and multiple infrared cameras are connected in parallel through power lines one by one so that the multiple infrared cameras are powered on and started. Each guardrail is powered on by the infrared camera to start the first electric push rod, and the first electric push rod is powered on by the infrared camera. The output end of an electric push rod pushes the slider to slide in the slide groove, the slider drives the push-pull block to move, the push-pull block pushes the push-pull rod, and the push-pull rod pushes the flap to deflect with two shaft sleeves as fulcrums, so that the flap blocks the gap between the two baffles to avoid gaps between the two baffles, so that the two baffles can be installed seamlessly, the gap between the guardrails is reduced, the dust overflow at the construction site is reduced, and the pollution to the surrounding environment is reduced. At the same time, the guardrail structure is simplified through the detachable and modular installation of the guardrail, which facilitates the rapid installation and disassembly of the guardrail.

[0036] 2. In this solution, when the distance between pedestrians and non-motor vehicles and the guardrail is less than the minimum distance, the swing program in the integrated terminal storage unit is started, and the output end of the second motor drives the driving gear to rotate, and the driving gear drives the driven gear to rotate by meshing with the driven gear. The driven gear drives the flip box to deflect in the flip groove through an extension shaft of the flip box, and then the gap drives the color laser to swing up and down. When the color laser needs to be positioned, the second electric push rod engages with the ratchet wheel in one direction by squeezing the pawl to lock the up and down swing of the color laser. When the color laser needs to swing left and right The infrared camera is powered on to start the stepper motor. The output end of the stepper motor drives the half gear to rotate. The half gear drives the deflection shaft to rotate by meshing with the deflection gear. The deflection shaft drives the swing frame to swing slightly in the flip box. The swing frame pushes the color laser to swing left and right in the arc groove. The color laser can move up, down, left and right, so that the laser emitted by the color laser can form different color luminous patterns on the ground. At the same time, the infrared camera has a built-in sounder to play warning words to the side end of the baffle to prevent pedestrians and non-motor vehicles from approaching the guardrail and avoid pedestrians and non-motor vehicles from approaching safety hazards.

[0037] 3. In this scheme, during the water mist dust reduction process, the adjustment mechanism moves the colored laser to illuminate the guide route for pedestrians and non-motor vehicles on the ground, prevent pedestrians and non-motor vehicles from approaching the guardrail, guide pedestrians and non-motor vehicles to travel outside the dust reduction water mist, prevent the dust reduction water mist from blocking the line of sight of pedestrians and non-motor vehicles, prevent the safety hazard of collision between pedestrians and non-motor vehicles, and realize the avoidance guidance of pedestrians and non-motor vehicles.

[0038] 4. In this scheme, during the up and down swinging process of the color laser, when the color laser swings to the required up and down deflection angle, the output end of the second electric push rod pushes the pawl to engage with the ratchet wheel, limiting and locking the up and down swinging of the color laser, avoiding the up and down vibration of the color laser during the left and right swinging process of the color laser, and improving the clarity of the color laser pattern formed by the color laser emission. Whenever the color laser needs to be retracted into the flip groove, the flip box is pressed down to drive the second adapter block to be pressed down, and the second adapter block is pressed down to drive the lifting rod to be pressed down, and the lifting rod pulls the lifting block to be pressed down, and the lifting block pulls the sealing cover to flip downward, so that the sealing cover seals and covers the flip groove. The sealing cover blocks the flip groove, thereby reducing the oxidation corrosion of the color laser by dust and water vapor. At the same time, the unfolded sealing cover is used to reduce the condensation of water mist on the color laser launch head, reduce laser scattering, improve the clarity of the ground color laser pattern, and effectively improve the guiding ability of the guardrail for pedestrians and non-motor vehicles.

[0039] 5. In this scheme, whenever the color laser needs to be retracted into the flip groove, the flip box is pressed down to drive the second adapter block to be pressed down, the second adapter block is pressed down to drive the lifting rod to be pressed down, the lifting rod pulls the lifting block to be pressed down, and the lifting block pulls the sealing cover to flip downward, so that the sealing cover seals and covers the flip groove. The sealing cover blocks the flip groove to reduce the oxidation corrosion of the color laser by dust and water vapor. At the same time, the unfolded sealing cover is used to reduce the condensation of water mist on the color laser emission head, reduce laser scattering, improve the clarity of the ground color laser pattern, and improve the guardrail's ability to guide pedestrians and non-motor vehicles.

[0068] The driving assembly includes a driven gear 39, a driving gear 40, a gear cover 41 and a second motor 42. The gear cover 41 is sleeved on an extended end of an axis rod of the flip box 27, and the gear cover 41 is fixedly connected to a side end of the deflection cover 43. The driven gear 39 is fixedly connected to an extended end of an axis rod of the flip box 27, and the driven gear 39 is located in the gear cover 41.

Avoidance guidance: During the water mist dust reduction process, the adjustment mechanism moves the color laser (28) to illuminate the guide route for pedestrians and non-motor vehicles on the ground, thereby preventing pedestrians and non-motor vehicles from approaching the guardrail and guiding pedestrians and non-motor vehicles to travel outside the dust reduction water mist, thereby preventing the dust reduction water mist from blocking the sight of pedestrians and non-motor vehicles and preventing the potential safety hazard of collision between pedestrians and non-motor vehicles, thereby achieving evasive guidance for pedestrians and non-motor vehicles.
