Description

Technical Field

[0001] The present application relates to the technical field of movable guardrails, and in particular to a guardrail device and a method of using the same. Background Art

[0002] The central median guardrail mainly refers to the guardrail located in the central median of the highway. It plays an important role in preventing out-of-control vehicles from crossing the central median and entering the opposite lane, and protecting the structures in the median. The central median guardrail of the highway is generally equipped with movable guardrails at the opening. These movable guardrails can be roughly divided into three categories: the first category is movable guardrails that are easy to open and move but not anti-collision; the second category is movable guardrails with uncertain anti-collision capabilities and difficult to open and move; the third category is reinforced movable guardrails, but they are difficult to repair, replace, and increase or decrease.

[0003] These movable guardrails play a very important role and are also the high-end area where accidents occur. Many types of accidents occur at the opening of the guardrail in the central dividing strip. Based on this, the present application proposes a guardrail device that can achieve a balance between easy opening and moving functions, convenient maintenance and anti-collision capabilities.

[0050] In the description of this application, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in this application after combining the specific content of the technical solution.

[0051] Reference Figures 1 to 4 The guardrail device of the first embodiment of the present application includes a frame structure 100, a first structure 200, a first caster component 300, a second structure 400, a supporting component 500, a first elastic component 600 and a second elastic component 700.

[0052] The first structure 200 is movably arranged on the frame structure 100 in a direction relatively close to or away from the bottom of the frame structure 100; the first caster component 300 is arranged at the bottom of the first structure 200; the second structure 400 is movably arranged on the frame structure 100 in a direction relatively close to or away from the bottom of the frame structure 100; the supporting component 500 is arranged at the bottom of the second structure 400; the first elastic component 600 is arranged on the frame structure 100 and acts on the first structure 200, so that the first caster component 300 has two states of extending out of the bottom of the frame structure 100 or retracting into the bottom of the frame structure 100; the second elastic component 700 is arranged on the frame structure 100 0 and acts on the second structure 400, so that the supporting component 500 has two states of extending out of the bottom of the frame structure 100 or retracting into the bottom of the frame structure 100; the weight of the first structure 200 is adjustable, and the first structure 200 can overcome the elastic force of the first elastic component 600 when the weight is greater than the first preset weight and move in the direction close to the bottom of the frame structure 100, so that the first caster component 300 can extend out of the bottom of the frame structure 100; the weight of the second structure 400 is adjustable, and the second structure 400 can overcome the elastic force of the second elastic component 700 when the weight is greater than the second preset weight and move in the direction close to the bottom of the frame structure 100, so that the supporting component 500 can extend out of the bottom of the frame structure 100.

[0053] It can be understood that the basic protection function of the guardrail device is ensured by the frame structure 100, and the first structure 200 and the second structure 400 with adjustable weight are set in the frame structure 100 and linked with the elastic component, so that the state of the guardrail device can be switched by increasing or decreasing the weight, which does not affect the normal use and is easy to move, thereby achieving a balance between easy-to-open and mobile functions and outstanding anti-collision capabilities, and facilitating maintenance, replacement, increase or decrease, and change of position.

[0054] In some embodiments, the weights of the first structure 200 and the second structure 400 can be adjusted separately. If the guardrail device needs to be moved, the weight of the second structure 400 needs to be reduced to retract the support component 500, and the weight of the first structure 200 needs to be increased to make the first caster component 300 fall to the ground. Similarly, if the position of the guardrail device needs to be fixed, the weight of the second structure 400 needs to be increased to extend the support component 500, and the weight of the first structure 200 needs to be reduced to retract the first caster component 300. In this embodiment, the weights of the first structure 200 and the second structure 400 need to be adjusted simultaneously.

[0055] In some embodiments, if the guardrail device needs to be moved, the weight reduced in the first structure 200 can be directly added to the second structure 400. If the position of the guardrail device needs to be fixed, the weight increased in the first structure 200 can be directly obtained from the second structure 400. In this embodiment, the weight adjustment of the first structure 200 and the second structure 400 is more reasonable and more convenient for on-site use.

[0056] In some embodiments, the elastic force of the first elastic component 600 and the second elastic component 700 can be adaptively adjusted, so that the first structure 200 and the second structure 400 can respectively overcome the elastic force of the first elastic component 600 and the second elastic component 700 and switch states after being adjusted to appropriate weights. By quantifying the weight and elastic force, convenience and accuracy of operation can be provided.

[0057] In some embodiments, the methods of increasing or decreasing weight include but are not limited to increasing or decreasing weight blocks, removing or installing components with a certain weight, and increasing or decreasing water or other liquids in a container to achieve weight adjustment. In this case, corresponding installation spaces or accommodation spaces can be adaptively set on the first structure 200 and the second structure 400, and the guardrail function of the frame structure 100 is not affected.

[0058] In some embodiments of the present application, multiple guardrail devices are provided, and adjacent guardrail devices are detachably hinged together through the connecting device 800. It can be understood that the guardrail devices are arranged in sequence on the highway to form a central median guardrail, wherein the detachable connection through the connecting device 800 can facilitate maintenance and replacement, and is convenient for use; the adjacent guardrail devices are hinged together through the connecting device 800 to facilitate adjustment to adapt to the extension direction of the highway, and after adjustment, the guardrail device is fixed by reducing the weight of the first structure 200 and increasing the weight of the second structure 400, which does not affect normal use on the basis of facilitating adjustment.

[0059] In some embodiments of the present application, the connection device 800 includes a latch 810 and a mounting bracket 820. The mounting brackets 820 are respectively provided on both sides of the frame structure 100. The end of the mounting bracket 820 relatively far from the frame structure 100 is provided with a fixed end for the latch 810 to pass through. The latch 810 passes through the adjacent fixed ends so that the adjacent guardrail devices can be detachably hinged together. It can be understood that the mounting bracket 820 is set as a triangular bracket, one side of the triangle is set on both sides of the frame structure 100, and the corner opposite to the side is provided with a fixed end. After the latch 810 passes through each fixed end of the adjacent guardrail device, the adjacent guardrail devices can be hinged together. When disassembly is required, the latch 810 can be removed, which is very convenient, thereby facilitating maintenance, replacement, addition and reduction, temporary opening and change of position.

[0060] In some embodiments, the triangular steel frame is welded by two angle steels or channel steels to form three shapes. One end can be a steel ring or steel pipe for installing the steel pipe plug 810. The other end is welded to the middle of the guardrail frame 110 to form a whole. The front and back are staggered to ensure that when the two guardrails are connected, the ending elevation directions do not overlap. The end of the bracket is an annular structure, and the inner diameter is slightly smaller than the outer diameter of the steel pipe plug 810. The guardrail is added and formed into a whole by inserting the steel pipe, and the guardrail is removed by pulling out the steel pipe. The outer diameter of the steel pipe plug 810 is smaller than the inner diameter of the steel ring or steel pipe of the triangular steel frame, and can be freely pulled out or inserted. A steel limiter is welded on one end, and a bolt or locking design is used to fix the other end to ensure that the guardrail will not loosen during the movement and will not be disassembled casually when fixed.

[0061] In some embodiments of the present application, the frame structure 100 includes a guardrail frame 110, a support rod 120 and a reaction frame 130. Two second structures 400 are provided and are respectively located on both sides of the first structure 200 to form a group of guardrail structures. Multiple groups of guardrail structures are arranged at intervals on the frame structure 100. Support rods 120 are provided between adjacent groups of guardrail structures. The support rods 120 are used to support the guardrail frame 110. Each reaction frame 130 is arranged on the frame structure 100 and is used to limit each support rod 120 respectively. It can be understood that the guardrail device is composed of multiple first structures and second structures 400 to increase its thickness to ensure the protection function. At the same time, the support rod 120 is used for support. When the first structure 200 is lowered, the second structure 400 cooperates with the support rod 120 to support the guardrail frame 110. Similarly, when the second structure 400 is lowered, the first structure 200 cooperates with the support rod 120 to support the guardrail frame 110, so that each first structure 200 and the second structure 400 can adjust the weight and move without causing the guardrail frame 110 to fall to the ground.

[0062] In some embodiments, the support rod 120 is detachable and needs to be installed or replaced with a water tank. It can be pulled out horizontally. The steel pipe limit frame is located in the top frame of the guardrail frame 110. It is mainly rectangular and can be welded with steel sections. The principle is that it does not affect the entry and exit of the water tank. It limits the support steel pipe and transmits force.

[0063] In some embodiments of the present application, the first structure 200 includes a first water tank, and the second structure 400 includes a second water tank. The weight of the first water tank and the second water tank is adjusted by adding or draining water. It is understandable that the rechargeable water tank is mainly made of plastic, and the overall shape is like a "mountain", and the concave part is mainly used to support the guardrail frame 110. A section of the guardrail is generally composed of two small second water tanks and a large first water tank. The first water tank is used to move the guardrail, and the second water tank is used to fix the guardrail. The bottom of the first water tank is generally wider to improve stability during movement.

[0064] In some embodiments, there are three water inlets on the top of the water tank to increase the water filling speed and filling degree, and can also be used for pumping water. When the guardrail needs to be moved, open the top cover of the first water tank and the second water tank, insert the water pumping pipe of the sprinkler truck into the water tank B, and connect the water outlet pipe to the first water tank to transfer the water from the second water tank to the first water tank. You can also use the principle of siphon to use a water pipe, or a pump to directly pump water from the first water tank to the first water tank.

[0065] In some embodiments, the supporting effect of the supporting rigid rod is utilized, and after the weight of the water tank is reduced by pumping water, the bottom spring lifts the water tank, and the water tank can support the bracket to ensure that the guardrail frame 110 is suspended and does not touch the ground during movement, and the universal wheels do not touch the ground when fixed.

[0066] In some embodiments of the present application, each first water tank is provided with a first connecting interface 210, and the first connecting interface 210 is provided with a first valve 220, and the first valve 220 is used to set a first connecting pipe, and the first connecting pipe is used to connect a water source or connect at least two groups of first water tanks; each second water tank is provided with a second connecting interface 410, and the second connecting interface 410 is provided with a second valve 430, and the second valve 430 is used to set a second connecting pipe 420, and the second connecting pipe 420 is used to connect a water source or connect at least two groups of second water tanks. It can be understood that there are several water outlets at the front and rear ends of the water tank, which adopt a snap-on or threaded design, and can be connected to an external valve for connecting a corrugated hose. The position and the frame must be considered at the same time to ensure that the reinforcement of the frame does not affect the use of the water tank outlet. When it is necessary to remove a certain section of the guardrail separately, first close the valves of the two nearby sections of the guardrail to ensure that there is no water leakage, and then remove the corrugated pipe.

[0067] In some embodiments, the connecting bellows is mainly made of durable plastic, and its main function is to connect all water tanks, that is, as long as one of the water tanks is filled or drained, it can ensure that all connected water tanks can be filled or drained at the same time, without the need to fill or drain each water tank. The length is longer than the triangular steel frame to ensure that the bellows is not stressed when the guardrail moves.

[0068] In some embodiments of the present application, the frame structure 100 includes a first base 140, which is slidably arranged on the frame structure 100 along the height direction, the first structure 200 is arranged on the surface of the first base 140, the first caster component 300 is arranged on the bottom surface of the first base 140, and the first elastic component 600 is arranged between the bottom surface of the first base 140 and the bottom of the frame structure 100; the frame structure 100 includes a second base 150, which is slidably arranged on the frame structure 100 along the height direction, the second structure 400 is arranged on the surface of the second base 150, the support component 500 is arranged on the bottom surface of the second base 150, and the second elastic component 700 is arranged between the bottom surface of the second base 150 and the bottom of the frame structure 100. It can be understood that three integral steel sheet piles are used as the base of the water tank guardrail at the bottom of the frame, which can move up and down and are not fixed to the frame. The number and size of the springs under the steel plate are calculated and determined according to the gravity of the water tank when it is full of water, ensuring that the water tank can be fully compressed when it is 70% full of water and can be fully bounced up when it is not less than 20%.

[0069] In some embodiments of the present application, a second caster component 160 is further provided at the bottom of the frame structure 100, and the second caster component 160 can cooperate with the first caster component 300 in the extended state, and the support component 500 is at a lower position in the height direction relative to the second caster component 160 when in the extended state. It can be understood that the second caster component 160 is used to prevent overturning and assist movement when the guardrail moves, is fixed at the bottom of the frame, and will not rise or fall with the water tank. When the guardrail is fixed, the small universal wheel does not touch the ground.

[0070] In some embodiments, the diameter of the first caster component 300 is larger than the diameter of the second caster component 160. The first caster component 300 is used to move the guardrail, and the second caster component 160 is used to assist in movement. In some embodiments, the first caster component 300 and the second caster component 160 are both configured as universal wheels for easy movement.

[0071] Reference Figures 1 to 4 The method for using the guardrail device of the second aspect of the present application may be the method for using the guardrail device of the first aspect of the present application, and the method for using the guardrail device includes the following steps:

[0072] When the guardrail device needs to be moved, the deadweight of the second structure 400 is reduced until the second elastic component 700 at the bottom lifts up the second structure 400, so that the support component 500 is retracted into the frame structure 100; the deadweight of the first structure 200 is increased and exceeds the thrust of the first elastic component 600 at the bottom, so that the first caster component 300 falls to the ground and can be moved;

[0073] When the guardrail device needs to be fixed, the deadweight of the first structure 200 is reduced until the first elastic component 600 at the bottom lifts up the first structure 200 so that the first caster component 300 is retracted into the frame structure 100; the deadweight of the second structure 400 is increased and exceeds the thrust of the second elastic component 700 at the bottom, so that the support component 500 falls to the ground and can be fixed.

[0074] It is understandable that this guardrail device is suitable for use as a temporary or permanent guardrail in the middle of two-way lanes such as highways and urban roads. Its main advantages and features are that it is easy to repair, replace, add or remove, temporarily open, and change positions. Replacement and repair do not require large equipment, which is convenient. Plastic water tanks and steel structures are easier to design and have high plasticity. Compared with concrete, water tanks can play a certain buffering role, reduce the degree of damage after a car collision, and have higher safety. The movable design that does not require large equipment is more convenient when temporary openings are needed on highways, and has high flexibility. It can be applied to the design of tidal lanes to alleviate highway congestion in the future.

[0075] In some embodiments, the guardrail installation method includes:

[0076] S1: Prepare a corresponding number of frame structures 100, connecting devices 800 and rechargeable water tanks according to the length of the guardrail to be used;

[0077] S2: Place the frame structure 100 at the specified position, align the front and rear triangular mounting brackets 820 and insert the steel pipe pins 810 to fix them, and then fix them with bolts;

[0078] S3: Place the first water tank and the second water tank into the frame structure 100, install water valves at the water inlets and outlets, connect the adjacent first water tanks with a corrugated hose, connect the adjacent second water tanks with a corrugated hose, and open the valves;

[0079] S4: Insert the support rod 120, open the second water tank cover, and use a sprinkler truck to inject water into the second water tanks on both sides of the guardrail until the water tank squeezes the bottom spring, and the support foot extends out of the bottom of the frame and exceeds the second caster and disappears.

[0080] S5: Check that the water levels of the second water tanks on both sides of all guardrail water tanks are roughly balanced and the support frames are all extended. Then stop filling the water, turn off the inlet and outlet valves to prevent leakage in individual water tanks from causing leakage in all water tanks, and then cover them.

[0081] In some embodiments, the method of replacing or temporarily opening the entire guardrail section includes:

[0082] S1: Open the cover of the water tank where the guardrail needs to be replaced, drain the water with a sprinkler truck, remove the outlet connection hose and water valve, unscrew the nut of the bolt, pull out the steel pipe pin 810, and move and remove the guardrail that needs to be replaced or temporarily opened.

[0083] S2: Place the new guardrail and water tank at the position of the guardrail that has been moved, insert the steel pipe plug 810 into the hole of the triangular connecting device 800, install the bolts and nuts, install the outlet valve and connecting hose, insert the steel pipe, open the lid, fill the water tank with water, and close the lid to complete the replacement.

[0084] In some embodiments, the water tank replacement method includes:

[0086] S2: Place the water tank to be replaced into the frame, install the outlet valve and connecting hose, insert the steel pipe, open the lid, fill water into the water tank, and close the lid to complete the replacement.

[0087] In some embodiments, the method for transferring the guardrail in a short distance comprises:

[0088] S1: Open the water valves and covers of the water outlets of the second water tanks and the first water tank on both sides of the guardrail, and use at least two sprinkler trucks or pumps to pump the water from the second water tanks on both sides of the guardrail to the central first water tank at the same time.

[0089] S2: The weight of the second water tank decreases, the bottom spring lifts the second water tank, the second water tank lifts the support rod 120 steel pipe, and the support frame is retracted into the frame. As the weight of the first water tank increases and exceeds the thrust of the bottom spring, the first caster component 300 falls to the ground.

[0090] S3: Check that the water levels of all the first water tanks are roughly balanced, and the first caster components 300 are all extended, and the support frame is retracted into the frame, then stop filling water, and then turn off the inlet and outlet valves to prevent leakage of individual water tanks from causing leakage of all water tanks, and then cover the lid.

[0091] S4: Disassemble the outlet connection hoses and water valves of the first and last guardrail sections that need to be transferred as a whole, unscrew the nuts of the bolts, and pull out the steel pipe pin 810.

[0092] S5: After arranging a car or train to slowly drag the first section of the guardrail frame 110 to the specified position, the position is manually fine-tuned and temporarily fixed.

[0093] S6: Open all water tank covers and outlet valves, and use at least two sprinkler trucks or pumps to pump water from the central first water tank to the second water tanks on both sides of the guardrail.

[0094] S7: The deadweight of the first water tank is reduced, and the bottom spring lifts up the water tank. The first water tank lifts up the support rod 120 steel pipe, and the first caster component 300 is retracted into the frame.

[0095] S8: As the deadweight of the second water tank increases and exceeds the thrust of the bottom spring, the support component 500 falls to the ground. Check that the water levels of the second water tanks on both sides of all guardrail water tanks are roughly balanced and that the support components 500 are fully extended. Then stop filling water and turn off all inlet and outlet valves to prevent leakage of individual water tanks from causing leakage of all water tanks. Then close the lid to complete the transfer.
