Description

Technical Field

[0001] The invention relates to the technical field of traffic signs, and in particular to a traffic sign plate structure capable of reducing wind load and hydraulically self-resetting. Background Art

[0002] At present, the calculation of sign structures is mainly to verify whether the supporting structure can withstand the pressure of wind on the sign board. The wind speed is high in coastal areas and pass areas such as Xinjiang. The design requirements are based on the local wind speed of once in fifty years. Large sign boards require large supporting structures such as gantry, multi-column, and cantilever structures, which are very thick and result in serious waste of materials.

[0003] The design of the sign structure requires calculation of the wind speed with a 50-year return period. The probability of a maximum wind speed occurring during actual use is relatively small, which is too wasteful for a design life of less than 10 years. Therefore, the present invention proposes a traffic sign structure that can reduce wind loads and hydraulically self-reset. Summary of the invention

[0004] The object of the present invention is to provide a traffic sign plate structure which can reduce wind load and hydraulically reset itself, so as to solve the above technical problems.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A traffic sign plate structure capable of reducing wind load and hydraulically self-resetting comprises a sign plate, wherein the sign plate is composed of a plate A and a plate B, and the plates A and B are rotatably connected via a rotating assembly, the bottom of the plate B is fixed to the ground via a supporting frame, and a supporting assembly is further provided between the plates A and B;

[0007] The support assembly includes four cylinders, which are respectively fixed to the upper parts of both sides of the front and back sides of plate A. A piston is arranged inside the cylinder, a piston rod is fixed on one side of the piston, the top end of the piston rod penetrates and extends to the outside of the cylinder, the top end of the piston rod is fixed to plate B, the piston divides the inside of the cylinder into cavity A and cavity B, hydraulic oil is arranged inside cavity B, and cavity A and cavity B are connected through oil pipes A and oil pipes B, and safety valves A and safety valves B are respectively arranged on oil pipes A and oil pipes B.

[0008] Preferably, the rotating assembly includes a long strip and a short block, the long strip is fixed to the middle of the top of plate A, and two short blocks are provided and are respectively fixed to both sides of the bottom of plate B. Transverse through holes are opened in the middle of the long strip and the short block, and the long strip and the short block are rotatably connected by a screw rod passing through the inside of the transverse through hole, and nuts are threadedly connected at both ends of the screw rod.

[0009] Preferably, the cylinder barrel and the piston rod are both arc-shaped, and the arc centers of the cylinder barrel and the piston rod are located on the central axis of the screw rod.

[0010] Preferably, the safety valve A and the safety valve B are both adjustable safety valves, and their opening pressures can be set arbitrarily within a certain range.

[0011] Preferably, the flow direction of the safety valve A is from cavity A to cavity B, and the flow direction of the safety valve B is specifically from cavity B to cavity A.

[0012] Preferably, a sealing ring is provided at the position where the piston rod passes through the cylinder.

[0013] Preferably, a spring is fixed to the bottom of the piston, and the bottom end of the spring is fixed to the bottom of the inner wall of cavity B.

[0014] Preferably, the ends of the cylinder barrel and the piston rod are both welded with connecting plates, and the two connecting plates are respectively fixed to the surfaces of plate A and plate B by bolts.

[0015] Preferably, the bottom of the plate B is fixed to the ground through a support frame, and when the plate A is in a vertical state, the piston is in the middle of the cylinder.

[0016] The beneficial effects of the present invention are:

[0017] 1. The present invention adopts a bendable sign board structure. When the wind pressure reaches a certain level (which can be set), the sign board can bend after being stressed, and the stress-bearing area is reduced. No bulky supporting structure is required, which saves the material of the supporting structure and is low-carbon and environmentally friendly.

[0018] 2. The present invention adjusts the safety value of the safety valve B to a lower level. When there is no wind pressure, the thrust generated by the spring returning to its original state can push up the piston and the piston rod. The hydraulic oil in the cavity A enters the cavity B through the oil pipe B, and the piston rod returns to its original position, pushing the plate A to return to a vertical state, and supporting the plate A to keep it in a vertical state.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.

[0025] The specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0026] Example

[0027] like Figure 1-4 As shown, a traffic sign structure capable of reducing wind load and hydraulically self-resetting includes a sign board, wherein the sign board is composed of a plate A1 and a plate B2, and a rotational connection is achieved between the plate A1 and the plate B2 via a rotational assembly 3, and a support assembly 4 is also arranged between the plate A1 and the plate B2.

[0028] The rotating assembly 3 includes a long strip 31 and a short block 32. The long strip 31 is fixed at the middle of the top of the plate A1. Two short blocks 32 are provided and are respectively fixed at both sides of the bottom of the plate B2. A transverse through hole 33 is opened in the middle of the long strip 31 and the short block 32, and the long strip 31 and the short block 32 are rotatably connected by a screw 34 passing through the inside of the transverse through hole 33. Both ends of the screw 34 are threadedly connected with nuts 35. This structure enables the plates A and B to rotate relative to each other, that is, after the plate A rotates, the sign plate is bent as a whole, which reduces the force-bearing area and has strong wind resistance.

[0029] The support assembly 4 includes four cylinders 41, which are respectively fixed to the upper parts of both sides of the front and back sides of the plate A1. A piston 42 is arranged inside the cylinder 41, and a piston rod 43 is fixed to one side of the piston 42. The ends of the cylinder 41 and the piston rod 43 are welded with connecting plates 7, and the two connecting plates 7 are respectively fixed to the surfaces of the plates A1 and B2 by bolts 8. The top end of the piston rod 43 penetrates and extends to the outside of the cylinder 41. A sealing ring 5 is arranged at the position where the piston rod 43 penetrates the cylinder 41. The top end of the piston rod 43 is fixed to the plate B2. The piston 42 divides the inside of the cylinder 41 into a cavity A44 and a cavity B45. The inside of the cavity B45 is provided with hydraulic oil 46. The bottom of the piston 42 is fixed with a spring 6, and the bottom end of the spring 6 is fixed to the cavity The bottom of the inner wall of body B45, and cavity A44 and cavity B45 are connected through oil pipes A47 and B48, and safety valves A49 and B410 are respectively arranged on oil pipes A47 and B48. When plate A1 is in a vertical state, piston 42 is in the middle of the cylinder 41. When the wind pressure is greater than the threshold of safety valve A, safety valve A will open, and the hydraulic oil inside cavity B enters cavity A44 through oil pipe A47. The piston rod moves downward inside the arc-shaped cylinder, and the leeward cotton of plate A1 loses its support and rotates relative to plate B2, presenting an inclined state. When there is no wind pressure, the thrust generated by the spring returning to its original state can push up the piston and the piston rod, and the hydraulic oil inside cavity A enters cavity B through oil pipe B, and the piston rod returns to its original position.

[0030] The cylinder 41 and the piston rod 43 are both arc-shaped, and the arc centers of the cylinder 41 and the piston rod 43 are located on the central axis of the screw 34. Since the arc centers of the cylinder 41 and the piston rod 43 are located on the central axis of the screw 34, the movement trajectory of the piston rod 43 will not interfere with the movement trajectory of the plate A.

[0031] The flow direction of the safety valve A49 is from cavity A44 to cavity B45, and the flow direction of the safety valve B410 is specifically from cavity B45 to cavity A44. Both the safety valve A49 and the safety valve B410 are adjustable safety valves, and their opening pressures can be set arbitrarily within a certain range. The threshold of the safety valve A49 is generally set higher, and the safety valve will only open when the pressure is high, so that the plate A1 will not bend easily. The threshold of the safety valve B410 is generally set smaller, which is convenient for the automatic resetting of the piston rod 43 and the plate A1.

[0032] During specific use, the thresholds of safety valve A and safety valve B are pre-set, and the threshold of safety valve A is set higher, while the threshold of safety valve B is set lower, so as to facilitate automatic resetting. When wind blows, plate A and piston rod 43 will bear these pressures, pushing the piston on the leeward side of the sign plate downward to squeeze the hydraulic oil inside cavity B. When the wind pressure is greater than the threshold of safety valve A, safety valve A will open, and the hydraulic oil inside cavity B enters cavity A44 through oil pipe A47. The piston rod moves downward inside the arc-shaped cylinder, and the leeward cotton of plate A1 loses its support and rotates relative to plate B2, becoming inclined, with a reduced force area and improved wind resistance. When there is no wind pressure, the thrust generated by the spring returning to its original state can push up the piston and piston rod, and the hydraulic oil inside cavity A enters cavity B through oil pipe B, and the piston rod returns to its original position, pushing plate A back to a vertical state, and supporting plate A to keep it in a vertical state.
