Description

Technical Field

[0001] This utility model relates to the field of guardrail installation technology, specifically a flat iron bending mechanism for guardrails. Background Technology

[0002] A corrugated steel guardrail is a modular, movable steel guardrail used at openings in the median strip of highways. It consists of two corrugated steel guardrail panels and two posts fixedly clamped between them. During normal highway operation, the guardrail allows the posts to be easily inserted into pre-set insertion holes at the opening, providing isolation and protection. It also complements the existing guardrail along the outer edge of the highway, creating a neat and aesthetically pleasing appearance. In the event of a vehicle collision, the corrugated steel guardrail panels possess excellent impact resistance and energy absorption properties, making them less prone to damage while effectively protecting the vehicle and its occupants.

[0003] When installing corrugated guardrails, the corrugated flat iron is manufactured in a straight shape. When installing the curved section, workers need to first fix one end of the corrugated flat iron to the post, and then push the other end of the flat iron to bend it and make contact with the post before fixing it in place. However, bending the flat iron requires manual pushing, which is labor-intensive and prone to springback, causing installation accidents. Therefore, it is necessary to design a flat iron bending mechanism for guardrails to improve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flat iron bending mechanism for guardrails.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A flat iron bending mechanism for guardrails, comprising:

[0007] The system comprises two upright columns and an S-shaped flat iron. One end of the S-shaped flat iron is mounted on the surface of one upright column. A mounting base is detachably mounted on the surface of the other upright column. Two take-up rods are rotatably connected to the rear side of the mounting base. The two take-up rods are symmetrically installed vertically. A pull rope 1 and a pull rope 2 are wound around the surface of each take-up rod. The two ends of pull rope 1 and pull rope 2 are respectively wound around the left and right ends of the surface of the two take-up rods. One end of the S-shaped flat iron is fitted into the inner cavity of pull rope 1 and pull rope 2. The S-shaped flat iron is bent by winding pull rope 1 and pull rope 2.

[0008] Preferably, the front side of the mounting base is slidably connected to two arc-shaped clamps, and the column body is clamped between the two arc-shaped clamps.

[0009] Preferably, the front side of the mounting base has a movable cavity, and the rear side of the arc-shaped clamp is welded with a sliding block. The sliding block slides in the inner cavity of the movable cavity, and the inner cavity of the movable cavity is rotatably connected to a bidirectional threaded rod extending to the outside. The sliding block is threadedly connected to the surface of the bidirectional threaded rod.

[0010] Preferably, support plates are welded to both ends of the left and right sides of the rear side of the mounting base, and two take-up rods are rotatably connected between the support plates. A ratchet is fixedly installed at the right end of the take-up rod, and a pawl that cooperates with the ratchet is rotatably connected to the surface of the support plate.

[0011] Preferably, a gear is fixedly installed on the left end of each take-up rod, and the two gears are connected by a gear belt drive.

[0012] Preferably, it also includes a handwheel, which is detachably mounted on the left end of the bidirectional threaded rod and the take-up rod. The left end of both the bidirectional threaded rod and the take-up rod is provided with a slot, and a locking block is welded to the surface of the handwheel.

[0013] Preferably, rollers are fixedly installed at both ends of the upper and lower sides of the mounting base.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model achieves the winding of both ends of the pull rope one and pull rope two by rotating two winding rods, thereby pulling one end of the S-shaped flat iron and bending it towards the column body. When one end of the S-shaped flat iron is attached to the surface of the column body, it is installed to the column body by bolts, thereby saving manpower and making it easier for workers to bend and install the S-shaped flat iron.

[0016] 2. By setting up an arc-shaped clamp, this utility model can lock the mounting base onto the surface of a column body of different sizes when the size of the column body changes, thus meeting more installation needs.

[0017] 3. By using rollers, this utility model can prevent pull ropes one and two from contacting the surface of the mounting base during the winding operation. This reduces the winding resistance of pull ropes one and two and prevents friction damage, thus improving their service life. Attached Figure Description

[0025] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0026] In the following description, embodiments of the flat iron bending mechanism for guardrails of this utility model will be described with reference to the accompanying drawings.

[0027] Figure 1-4 This invention illustrates a flat iron bending mechanism for guardrails according to an embodiment of the present invention, which includes:

[0028] The system consists of two column bodies 1 and S-shaped flat iron 2. One end of the S-shaped flat iron 2 is mounted on the surface of one column body 1. A mounting base 3 is detachably mounted on the surface of the other column body 1. Specifically, two arc-shaped clamping plates 4 are slidably connected to the front of the mounting base 3, clamping the column body 1 between them. The arc-shaped clamping plates 4 allow the mounting base 3 to be locked onto the surface of different sized column bodies 1 when their dimensions change, meeting various installation requirements. Specifically, a movable cavity 8 is opened on the front of the mounting base 3, and a sliding block 9 is welded to the rear of the arc-shaped clamping plates 4. The sliding block 9 slides within the movable cavity 8. A bidirectional threaded rod 10 extending outwards is rotatably connected to the inner cavity of the movable cavity 8, and the sliding block 9 is threaded onto the surface of the bidirectional threaded rod 10. Two take-up rods 5 are rotatably connected to the rear of the mounting base 3, installed symmetrically. Specifically, support plates 16 are welded to both ends of the left and right sides of the rear of the mounting base 3, and the two take-up rods 5 are rotatably connected to the support plates. Between 16, a ratchet 17 is fixedly installed on the right end of the take-up rod 5. A pawl that works with the ratchet 17 is rotatably connected to the surface of the support plate 16. Specifically, a gear 11 is fixedly installed on the left end of each take-up rod 5. The two gears 11 are connected by a gear pulley 12. A pull rope 1 6 and a pull rope 2 7 are wound around the surface of the take-up rod 5. The two ends of pull rope 1 6 and pull rope 2 7 are wound around the left and right ends of the two take-up rods 5 respectively. One end of the S-shaped flat iron 2 is sleeved inside pull rope 1 6 and pull rope 2 7. The cavity is driven by the winding pull rope 1 6 and pull rope 2 7 to bend the S-shaped flat iron 2. Specifically, rollers 18 are fixedly installed at both ends of the upper and lower sides of the mounting base 3. By setting the rollers 18, when the pull rope 1 6 and pull rope 2 7 are wound up, the pull rope 1 6 and pull rope 2 7 can be prevented from contacting the surface of the mounting base 3. This reduces the resistance of the pull rope 1 6 and pull rope 2 7 during winding and prevents friction damage to the pull rope 1 6 and pull rope 2 7, thus improving the service life of the pull rope 1 6 and pull rope 2 7.

[0029] It also includes a handwheel 13, which is detachably installed on the left end of the bidirectional threaded rod 10 and the take-up rod 5. The left end of both the bidirectional threaded rod 10 and the take-up rod 5 is provided with a slot 14, and a locking block 15 is welded to the surface of the handwheel 13.

[0030] Among them, the pull rope 16 and pull rope 27 are made of nylon rope, polyethylene rope or polyester rope, all of which are multi-strand braided, and have the characteristics of being wear-resistant and not easy to rot, making them suitable for long-term outdoor use.

[0031] Working principle: When using this utility model, the user fixes one end of the S-shaped flat iron 2 and one column body 1, then loops the pull rope 1 6 and pull rope 2 7 onto the other end of the S-shaped flat iron 2, and installs the mounting base 3. By aligning the other column body 1 between the two arc-shaped clamping plates 4 and turning the handwheel 13, the bidirectional threaded rod 10 rotates in the inner cavity of the movable cavity 8, thereby causing the two arc-shaped clamping plates 4 to slide towards each other and clamp and lock the column body 1, thus completing the installation of the mounting base 3. Then, the handwheel 13 is pulled out and installed... On the surface of either take-up rod 5, turn the handwheel 13 to drive the take-up rod 5 to rotate, which in turn drives the gear 11 and gear pulley 12 to rotate, so that the two take-up rods 5 rotate synchronously. At this time, the two take-up rods 5 will simultaneously wind up both ends of the pull rope 1 6 and pull rope 2 7, so that the pull rope 1 6 and pull rope 2 7 pull the S-shaped flat iron 2 synchronously, and then drive the S-shaped flat iron 2 to bend towards the mounting base 3 until one end of the S-shaped flat iron 2 is attached to the surface of the column body 1. The S-shaped flat iron 2 and the column body 1 are fixed by threads, and the installation operation of the S-shaped flat iron 2 is completed.

[0032] In summary, this guardrail uses a flat iron bending mechanism. By rotating two take-up rods 5, the two ends of the pull rope 1 6 and pull rope 2 7 are wound up, thereby pulling one end of the S-shaped flat iron 2 and bending it towards the post body 1. When one end of the S-shaped flat iron 2 is attached to the surface of the post body 1, it is installed to the post body 1 with bolts, thus saving manpower and making it easier for workers to bend and install the S-shaped flat iron 2.

[0033] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
