Description

Technical Field

[0001] The invention relates to the technical field of guardrails, and in particular to a locking connector for anti-collision highway guardrails. Background Art

[0002] A crash-proof highway guardrail is a type of guardrail installed beside a highway, also known as a wire fence. It is often used in the construction of fences, borders, or secure areas to isolate and protect specific areas from unauthorized entry or damage. At the same time, wire fences are usually made of metal mesh and metal support columns, which have strong compression and impact resistance. When a vehicle or other object hits, the structure of the fence can disperse the impact force and reduce the damage caused by the impact.

[0003] At present, when multiple workers cooperate to manually bend the wire fence, if the operation is careless or the force is not well controlled, the wire fence will suddenly return to its original state, which will bounce the workers and cause injuries. In urban planning, the use and activities around the river can be effectively managed by setting up wire fences to protect the safety and functional integrity of the river and its surrounding facilities. However, the banks of some rivers are very steep, so that after the workers install the columns on the embankment, they stand on the river bank without stepping on it to gain leverage, making the installation process very difficult and dangerous.

[0030] Example

[0031] like Figure 1-6As shown, a locking connector for anti-collision highway guardrail proposed by the present invention comprises a pair of columns 1 and a wire fence 2 installed on the column 1, and the top of each column 1 is provided with a connector 11 for fixing the column 1 on the column 1, and further comprises: a first locking clamp 3 and a second locking clamp 4 rotatably clamped on the top of the column 1, and a pair of first protrusions 341 are provided with a clamping groove for clamping the connector 11 in the middle of the second locking clamp 4. A T-shaped clamp 31 is fixedly connected inside the first locking clamp 3 to separate a pair of steel wire ropes 34, and the function of the T-shaped clamp 31 is to separate the coils of the pair of steel wire ropes 34 to prevent the coils of the steel wire ropes 34 from being tangled and knotted; a pair of steel wire ropes 34, the steel wire rope 34 is a rope woven from many strands of steel wire, and is mainly used in industrial fields such as hoisting, lifting, and hanging ropes. It is usually twisted from multiple strands of steel wire (usually 6 or 8 strands), and each strand of steel wire is woven from multiple thin steel wires in parallel. This structure makes the steel wire rope have very high strength and wear resistance, and can withstand a large amount of tension and weight. A rotating mechanism is arranged on the first locking clamp 3 to tie up the end of the wire fence 2 that needs to be bent; a rotating mechanism is installed in the first locking clamp 3 and pulls one end of the wire fence 2 to the connecting piece 11 at the top of the column 1 for locking after manual rotation; an anti-reversal mechanism, which is rotatably connected in the first locking clamp 3 so that the rotating mechanism can only rotate in one direction, and a manually closed dial button 53 is provided on the anti-reversal mechanism. The position of the dial button 53 allows the staff to easily lift their fingers to dial the dial button 53 when operating the rotating handle 61; a switch mechanism is arranged at the connecting end of the first locking clamp 3 and the second locking clamp 4 so that the first locking clamp 3 and the second locking clamp 4 are connected and fixed.

[0032] Furthermore, the rotating mechanism includes a main gear 32 rotatably connected to the first locking clamp 3, and the first locking clamp 3 is internally rotatably connected to a pair of secondary gears 33 meshing with the main gear 32. The secondary gears 33 are fixedly connected to a rotating shaft 35, and the rotating shaft 35 is fixedly connected to one end of a steel wire rope 34. The other end of the steel wire rope 34 is movable through the first locking clamp 3 and is fixedly connected to a connecting lock buckle 37. The material of the connecting lock buckle 37 is metal, and its principle is the same as that of a key chain.

[0033] Among them, the outer wall of the second locking clamp 4 is fixedly connected with a pair of support seats 38 for the other end of the wire rope 34 to pass through and clamp the connecting lock buckle 37. The interior of the support seat 38 is rotatably connected with a rotating support rod 39. The function of the rotating support rod 39 is to reduce the friction between the wire rope 34 and the second locking clamp 4 when in use, so as to avoid the wire rope 34 from generating a large friction with the second locking clamp 4 when running, so that the wire rope 34 cannot support the operation.

[0034] Secondly, a rotating rod 36 is fixedly connected to the main gear 32 , and the outer wall of the first locking clamp 3 is fixedly connected to a supporting chassis 6 for one end of the rotating rod 36 to movably penetrate, and the end of the rotating rod 36 away from the main gear 32 is fixedly connected to a rotating handle 61 .

[0035] Furthermore, the anti-reversal mechanism includes a support rod 54 fixedly connected to the inner wall of the first locking clamp 3, a driving rod 52 is sleeved on the support rod 54, and the end of the driving rod 52 away from the support rod 54 is movably passed through the first locking clamp 3 and fixedly connected to a dial button 53, and the outer wall of the end of the driving rod 52 close to the support rod 54 is fixedly connected to an anti-rotation rod 5 for clamping the main gear 32, and the end of the anti-rotation rod 5 away from the driving rod 52 is provided with an inclined protrusion 55, and the function of the inclined protrusion 55 is to make it easier for the end of the anti-rotation rod 5 close to the main gear 32 to clamp the main gear 32. A push spring 51 is fixedly connected to the inner wall of the first locking clamp 3, and the function of the push spring 51 is to make the inclined protrusion 55 on the push anti-rotation rod 5 always clamp the main gear 32. The end of the push spring 51 away from the inner wall of the first locking clamp 3 is fixedly connected to the anti-rotation rod 5.

[0036] Furthermore, the switch mechanism includes a first protrusion 341 and a second protrusion 342 connected to one end of the first locking clamp 3 and the second locking clamp 4, and a sliding groove 343 is provided on the second protrusion 342. A return spring 345 is fixedly connected inside the sliding groove 343. The function of the return spring 345 is to make the sliding push plate 344 drive the sliding clamp 347 to always be stuck to the first protrusion 341 when the sliding push plate 344 is not subjected to tension. The end of the return spring 345 away from the inner wall of the sliding groove 343 is fixedly connected to the slider 346. The slider 346 is slidably connected inside the sliding groove 343. The other end of the slider 346 is fixedly connected to a limit block 348 to prevent the slider 346 from slipping out of the sliding groove 343. The function of the limit block 348 is to make the sliding push plate 344 slide horizontally in only one direction. One end of a pair of sliding blocks 346 is fixedly connected to a sliding push plate 344 , and a sliding clamping plate 347 clamping the first protrusion 341 is fixedly connected to the sliding push plate 344 .

[0037] In this embodiment, when it is necessary to use a locking connector for an anti-collision highway guardrail, such as Figure 1As shown, the first locking clamp 3 and the second locking clamp 4 are rotated so that the second locking clamp 4 clamps the connecting piece 11 at the top of the column 1, thereby preventing the first locking clamp 3 and the second locking clamp 4 from sliding off the column 1. Then, the first locking clamp 3 and the second locking clamp 4 are rotated and closed by the switch mechanism at the ends of the first locking clamp 3 and the second locking clamp 4, and the second protrusion 342 on the first locking clamp 3 and the first protrusion 341 on the second locking clamp 4 approach each other, and at this time, the sliding push plate 344 is pushed away from the first locking clamp 3, and the sliding push plate 344 drives the sliding clamp 347 to move, and then the first protrusion 341 and the second protrusion 342 are in close contact. At this time, the sliding push plate 344 is released, and the slider 346 in the slide groove 343 is subjected to the elastic tension of the reset spring 345, so that the slider 346 drives the sliding push plate 344 and the sliding clamp 347 to clamp the first protrusion 341, so that the first locking clamp 3 and the second locking clamp 4 are fixed on the top of the column 1. When disassembly is required, just reverse the above steps, which will not be described in detail here.

[0038] When it is necessary to bend one end of the wire fence 2 to the top of the column 1 and connect and lock it with the connecting piece 11, first push the dial button 53 downward, the dial button 53 drives the driving rod 52 to rotate, and the driving rod 52 drives the anti-rotation rod 5 to rotate around the support rod 54, so that the inclined protrusion 55 on the anti-rotation rod 5 is disengaged from the main gear 32. At this time, it is only necessary to connect the connecting lock buckle 37 on one end of a pair of secondary gears 33, and tie up the end of the wire fence 2 that needs to be bent, and then release the dial button 53. Then turn the rotating handle 61 to drive the rotating rod 36 to rotate, and the rotating rod 36 drives the main gear 32 to rotate. Since the main gear 32 and the pair of secondary gears 33 are meshed and connected, the main gear 32 drives the pair of secondary gears 33 to rotate, and the secondary gear 33 drives the steel wire rope 34 thereon to rotate, so that all the steel wire ropes 34 outside the first locking clamp 3 are rotated into the first locking clamp 3. At the same time, one end of the steel wire rope 34 pulls the wire fence 2 to bend slowly, until the wire fence 2 bends to contact the connecting piece 11 on the column 1, and the wire fence 2 can be installed on the column 1, which is safe and efficient.
