Description

Technical Field

[0001] The utility model relates to the technical field of buffer guardrails, and more specifically to an impact buffer guardrail for roads and bridges. Background Art

[0002] Buffer guardrail refers to a safety facility, usually used at the edges of traffic places such as roads and bridges, designed to reduce the impact force of vehicle collisions, thereby protecting the safety of pedestrians, vehicles and buildings. Buffer guardrail is usually made of metal, concrete or other wear-resistant materials. Its design structure can effectively reduce the damage caused by collisions and reduce the scope of the impact of accidents.

[0003] At present, during the use of the buffer guardrail in the prior art, since the existing buffer guardrail generally has only a simple structural design, it cannot effectively buffer the impact force of the impacting vehicle, which can easily cause the vehicle to break through the guardrail and cause casualties, which reduces the practicability of the equipment to a certain extent. In addition, the existing buffer guardrails are mostly integral structures that are not convenient for separate disassembly and assembly. When the buffer guardrail is damaged, it is not convenient to repair and replace it, which reduces the applicability of the equipment to a certain extent. Therefore, there is an urgent need for an impact buffer guardrail for roads and bridges to solve the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the utility model provides an impact buffer guardrail for a road bridge to solve the problems existing in the above-mentioned background technology.

[0005] The utility model provides the following technical solution: an impact buffer guardrail for a road bridge, comprising:

[0006] A mounting base plate, wherein the upper end surface of the mounting base plate is fixedly connected with a support pile and a support plate, and a buffer structure is arranged inside the mounting base plate and the support pile, one end of the buffer structure is arranged with a connecting structure, and protective rods are arranged inside both ends of the connecting structure;

[0007] A buffer structure, the buffer structure includes a fixing rod and a buffer groove, wherein the fixing rod is fixedly connected to the inside of the upper end surface of the mounting base plate, and the connecting rod is inserted into the inside of the supporting pile;

[0008] The connecting structure includes a connecting screw, and the connecting screw is threadedly connected to the inside of one end of the connecting rod.

[0009] Preferably, a T-shaped groove is provided inside the upper surface of the mounting base plate, and the fixing rod is fixedly connected to the inside of the T-shaped groove, and a first spring and a support rod are sleeved on the outer surface of the fixing rod, a T-shaped slider is provided on the outer surface of the lower end of the support rod, and the T-shaped slider is snap-fitted and slidably connected to the inside of the T-shaped groove, a connecting rod is fixedly connected to the outer surfaces of the upper and lower ends of one end of the support rod, a buffer groove is provided inside the upper and lower ends of the support pile, and the connecting rod is inserted into the buffer groove, and a second spring is sleeved on the outer surface of the connecting rod, and the impact force of the collision with the vehicle can be buffered by the elasticity of the first spring and the second spring.

[0010] Preferably, the two ends of the first spring respectively abut against one side surface inside the T-shaped slide groove and one side surface outside the T-shaped slider. When the T-shaped slider moves on the surface of the fixed rod, the T-shaped slider can reset itself through the elasticity of the first spring.

[0011] Preferably, a limiting ring is provided on the outer surface of the connecting rod, and the outer dimensions of the limiting ring are matched with the inner dimensions of the buffer groove, and the two ends of the second spring respectively abut against one side surface inside the buffer groove and one side surface of the limiting ring. This design enables the connecting rod to be more stable when moving inside the buffer groove, and the connecting rod can reset itself through the elasticity of the second spring itself.

[0012] Preferably, the connecting structure also includes a connecting tube, and one end of the connecting screw is fixedly connected to the connecting tube, and a movable slide groove is opened inside the connecting tube, force-bearing rods are inserted inside the two ends of the connecting tube, and a third spring is sleeved on the outer surface of the force-bearing rod, one end of the force-bearing rod is hingedly connected to the hinge rod, and one end of the hinge rod is hingedly connected to the insertion sleeve, the internal threads of the upper and lower ends of one end of the insertion sleeve are connected with a tightening bolt, and a protective rod is inserted inside the insertion sleeve, and when the protective rod is inserted into the insertion sleeve, the tightening bolt can be rotated to fix the position of the protective rod.

[0013] Preferably, a support ring is provided on the outer surface of the other end of the force-bearing rod, and the outer dimensions of the support ring are adapted to the inner dimensions of the movable slide groove, and the two ends of the third spring respectively abut against one side surface of the support ring and one side surface inside the movable slide groove. This design enables the force-bearing rod to be more stable when moving inside the movable slide groove, and the force-bearing rod can reset itself through the elasticity of the third spring itself.

[0014] The technical effects and advantages of the utility model are as follows: when the protective rod is hit by a vehicle, the protective rod moves backward and drives the locking bolts at both ends of the protective rod to rotate through the hinge rod. At this time, the force-bearing rod is forced to move outward inside the movable slide groove, and the impact force of the vehicle collision is buffered and unloaded through the elasticity of the third spring. When the impact force of the vehicle is too large, the connecting tube drives the connecting rod to move backward. At this time, the T-shaped slider moves on the outer surface of the fixed rod, and the connecting rod moves inside the buffer groove, and the impact force of the vehicle collision is buffered and unloaded through the elasticity of the first spring and the second spring. The impact force of the vehicle is shared synchronously through multiple sets of parallel equipment, which avoids the situation where the vehicle easily breaks through the guardrail and causes casualties, thereby improving the practicality of the equipment to a certain extent.

[0015] By rotating and removing the locking bolt, the protective rod can be taken out from the inside of the insertion sleeve, and then the connecting structure is rotated to allow the connecting screw to rotate inside the connecting rod. At this time, the connecting screw can be withdrawn from the inside of the connecting rod, thereby facilitating separate disassembly and assembly. At the same time, when the protective rod is damaged, it is also convenient to repair and replace it, which improves the applicability of the equipment to a certain extent. Moreover, its overall structural design is simple and reasonable, and it is highly practical and easy to promote and apply. BRIEF DESCRIPTION OF THE DRAWINGS

A T-shaped groove is opened inside the upper end surface of the installation base plate 1, and the fixing rod 41 is fixedly connected to the inside of the T-shaped groove, and a first spring 42 and a supporting rod 43 are sleeved on the outer surface of the fixing rod 41, and a T-shaped slider is arranged on the outer surface of the lower end of the supporting rod 43, and the T-shaped slider is slidably connected to the inside of the T-shaped groove, and the two ends of the first spring 42 are respectively against one side surface of the inside of the T-shaped groove and one side surface of the outside of the T-shaped slider, and the T-shaped slider arranged on the outer surface of the lower end of the supporting rod 43 is adapted to the inside of the T-shaped groove, when the equipment is subjected to external impact force, the T-shaped slider can move on the outer surface of the fixing rod 41 inside the T-shaped groove, and the first spring 42 is compressed by the movement of the T-shaped slider, so that the first spring 42 can buffer and unload the impact force through its own elasticity, and the T-shaped slider can reset itself after the impact ends;

[0026] The support plate 3 is triangular in shape and hollow inside. The support plate 3 is located at the upper end of the fixing rod 41 and the first spring 42. The support plate 3 can block rainwater and the like to prevent the first spring 42 from rusting due to rainwater and the like and affecting the use of the equipment.

[0027] A connecting rod 44 is fixedly connected to the outer surface of the upper and lower ends of one end of the support rod 43, a buffer groove 45 is opened inside the upper and lower ends of the support pile 2, and the connecting rod 44 is inserted into the inside of the buffer groove 45, and a second spring 46 is sleeved on the outer surface of the connecting rod 44, and a limiting ring is arranged on the outer surface of the connecting rod 44, and the outer size of the limiting ring is matched with the inner size of the buffer groove 45, and the two ends of the second spring 46 respectively abut against one side surface of the inside of the buffer groove 45 and one side surface of the limiting ring.

[0028] Embodiment 2

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, based on the same concept as the above embodiment, this embodiment further proposes: a connecting structure 5, the connecting structure 5 includes a connecting screw 51, and the connecting screw 51 is threadedly connected to the inside of one end of the connecting rod 44, a collar is arranged on the outer surface of one side of the connecting cylinder 52, and the inner size of the collar is adapted to the outer size of one end of the connecting rod 44, when the connecting screw 51 is completely threadedly connected to the inside of one end of the connecting rod 44, the collar is sleeved on the outer surface of one end of the connecting rod 44, at this time, the collar can be used to avoid the connection position of the connecting screw 51 and the connecting rod 44 from being eroded by rainwater to a certain extent, thereby improving the service life of the equipment to a certain extent;

[0030] The connecting structure 5 also includes a connecting tube 52, and one end of the connecting screw 51 is fixedly connected to the connecting tube 52, and a movable sliding groove 53 is opened inside the connecting tube 52, and a force-bearing rod 54 is inserted inside the two ends of the connecting tube 52, and a third spring 55 is sleeved on the outer surface of the force-bearing rod 54, one end of the force-bearing rod 54 is hingedly connected to a hinge rod 56, and one end of the hinge rod 56 is hingedly connected to an insertion sleeve 57, and the upper and lower ends of one end of the insertion sleeve 57 are internally threadedly connected with a tightening bolt 58, and a protective rod 6 is inserted inside the insertion sleeve 57. This design allows one end of the protective rod 6 to be inserted into one group of the two groups of insertion sleeves 57, and another group of protective rods 6 can be inserted into the other group of insertion sleeves 57. Therefore, by placing multiple groups of equipment in a row, multiple groups of equipment can be connected through the protective rod 6, thereby protecting the edge of the road bridge;

[0031] A support ring is provided on the outer surface of the other end of the force-bearing rod 54, and the outer size of the support ring is adapted to the inner size of the movable slide groove 53, and the two ends of the third spring 55 respectively abut against one side surface of the support ring and one side surface inside the movable slide groove 53. When the protective rod 6 is subjected to external force, the force-bearing rod 54 moves outward inside the movable slide groove 53, and the support ring simultaneously moves inside the movable slide groove 53 and compresses the third spring 55. At this time, the impact force can be buffered and unloaded by the elasticity of the third spring 55 itself, and the force-bearing rod 54 can be reset by itself after the impact ends.

[0032] Working principle: When the equipment is used, firstly, multiple sets of mounting base plates 1 are installed at appropriate positions by fixing bolts, then two sets of connecting screws 51 are rotated so that the two sets of connecting screws 51 are respectively threadedly connected to the inside of two sets of connecting rods 44, and one end of the protection rod 6 is inserted into the inside of the insertion sleeve 57, and then the tightening bolt 58 is rotated to fix the protection rod 6, thereby completing the connection between multiple sets of protection rods 6 and multiple sets of connecting structures 5 in turn, and protecting the edge of the road bridge through the connection of multiple sets of equipment in a row, and it is convenient to repair and replace the connecting structure 5 or the protection rod 6 when it is damaged;

[0033] When the protective rod 6 is hit by a vehicle, the protective rod 6 will move backwards, and the inserted sleeves 57 at both ends of the protective rod 6 will move synchronously, and the hinged rods 56 at both ends of the protective rod 6 will be hinged and rotated. At this time, the hinged rod 56 can pull the force-bearing rod 54 to move outward in the movable slide groove 53 opened in the connecting tube 52. At this time, the impact force of the vehicle collision can be buffered and unloaded by the elasticity of the third spring 55. When the impact force on the protective rod 6 is large, the external force borne by the force-bearing rod 54 reaches the maximum value, and the force-bearing rod 54 will drive the connecting tube 52 to move backwards, and the connecting tube 52 pushes the connecting rod 44 and the support rod 43 to move backwards. 44 moves backward inside the buffer groove 45 opened in the supporting pile 2, and can buffer and unload the impact force when the vehicle collides with it through the elasticity of the second spring 46 itself, and the T-shaped slider arranged on the outer surface of the lower end of the supporting rod 43 moves backward on the outer surface of the fixing rod 41, and can buffer and unload the impact force when the vehicle collides with it through the elasticity of the first spring 42 itself. When the buffer structure 4 in a group of equipment is subjected to a large impact and moves backward, it will drive the multiple groups of connected equipment in the row to change synchronously, and the impact force can be shared and borne by the multiple groups of interconnected equipment, which improves the buffering effect of the equipment to a certain extent. The above is the entire working principle of the present invention.
