Description

Technical Field

[0001] This utility model belongs to the technical field of corrugated beam guardrail construction equipment, specifically relating to a portable installation device for corrugated beam guardrails that improves installation quality, reduces labor intensity and labor costs for workers. Background Technology

[0002] Mountain roads are characterized by undulating terrain, numerous curves, steep slopes, and complex road conditions. Dangerous sections require the installation of corrugated beam guardrails for safety protection. Corrugated beam guardrails are a longitudinal energy-absorbing semi-rigid protective structure that efficiently absorbs vehicle collision energy through the deformation of the corrugated plates and the bending of the posts. This forces out-of-control vehicles to change direction, preventing them from running off the road or into oncoming lanes, significantly reducing the severity of traffic accidents and the loss of life and property.

[0003] The corrugated beams are uniformly processed into straight shapes in the factory. During the installation of curved sections, they need to be temporarily bent into an arc shape on-site. Typically, one end of the guardrail panel is first fixed to the post, and then 4-6 construction workers work together to press and bend the other end of the panel, fixing it to the post to form the corrugated guardrail. The corrugated beam crossbeams are made of thin steel plates, with a thickness of 2mm to 4mm. Currently, the on-site bending method for curved sections of the guardrail panels is usually done manually by pulling ropes and hammering with a wrench. This bending method has poor precision, high labor intensity, and low efficiency; it easily causes injuries to construction workers due to collisions, impacts, and elastic recoil, posing significant safety hazards; it also leads to safety and quality problems such as uneven alignment and misaligned joints, disrupting structural continuity, resulting in uneven force distribution during collisions, and reducing the overall energy absorption efficiency of the guardrail.

[0004] Therefore, there is an urgent need to develop a bending device for corrugated beams to meet the demand. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a portable installation device for corrugated beam guardrails that improves installation quality, reduces labor intensity and labor costs for workers.

[0006] The technical solution of this utility model is as follows: a portable installation device for a corrugated beam guardrail, comprising: a guardrail clamp for clamping a corrugated steel guardrail panel, a post clamp for fixedly connecting to a post, the post clamp being fixedly connected to a wire take-up device, the wire take-up device being fixed to one end of a steel strand, and the other end of the steel strand being fixedly integrated with the guardrail clamp.

[0007] The take-up device includes a housing, a driven shaft mounted on the side wall of the housing via bearings, a winch and a driven gear integrally mounted on the driven shaft, and a drive shaft located below the driven shaft mounted on the side wall of the housing via bearings, with both ends of the drive shaft extending outside the housing, and a drive gear meshing with the driven gear fixed on the drive shaft.

[0008] The sleeve of the winch is fixed to one end of the steel strand, and the other end of the steel strand passes through the wire hole and is fixed to the guardrail clamp located outside the housing.

[0009] The housing is fixed to the column clamp as a whole by a connector.

[0010] To ensure safety during use, the above solution further includes: a ratchet fixed to one end of the drive shaft, a pawl above the ratchet, the pawl being fixed to the outer wall of the housing by a pin, the pawl swinging along the pin under external force, the pawl being fixedly connected to one end of a return spring, and the other end of the return spring being fixed to the outer wall of the housing.

[0011] Under normal conditions, the pawl engages with the ratchet.

[0012] For ease of operation, in the above scheme, a rocker arm is further fixed at one end of the drive shaft.

[0013] To ensure the clamping and fixing of the corrugated steel guardrail, the above solution further includes: the guardrail clamp comprising two clamping plates that match the corrugation of the corrugated steel guardrail, the two clamping plates being fixed together by bolts, and the other end of the steel strand passing through the wire hole and being fixed together with one of the clamping plates.

[0014] To avoid damaging the anti-corrosion layer of the corrugated steel guardrail during operation, the above solution further includes: a rubber pad layer is provided on the inner plate surface of the clamp plate.

[0015] To ensure the clamping and fixing of the column, the above solution further includes: the column clamping fixture includes two symmetrically arranged column clamping fixture plates with arc-shaped portions, and the two sides of the column clamping fixture plates have connecting plates;

[0016] The two column clamping plates are fixed together by bolts passing through the connecting plate, and the clamping cavity enclosed by the arc-shaped parts on the two column clamping plates matches the outer diameter of the column.

[0017] To prevent damage to the anti-corrosion layer of the column during operation, the above solution further includes: a rubber pad layer on the inner plate of the column clamp plate.

[0018] Due to its structure, this utility model improves installation quality, reduces worker labor intensity, and lowers labor costs. Specifically:

[0019] 1. Mechanical controllable line winding is achieved through gear reduction and winch disc, which precisely controls the bending curvature of the wavy steel guardrail to ensure a smooth line shape.

[0020] 2. The bending of the corrugated steel guardrail can be completed by a single person, which increases the construction efficiency by more than 50%. The process changes from multi-person collaboration to single-person operation, reducing manpower input and thus reducing labor costs.

[0021] 3. Gear reduction and torque increase reduce operating force by 80%, making the rocker arm lightweight and labor-saving, which can be operated by women or those with weaker physical strength, thus reducing the labor intensity of workers. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 5 As shown, a portable installation device for a corrugated beam guardrail includes: a guardrail clamp 3 for holding a corrugated steel guardrail panel 1, a post clamp 4 for fixedly connecting to a post 2, the post clamp 4 being fixedly connected to a wire take-up device 5, the wire take-up device 5 being fixed to one end of a steel strand 6, and the other end of the steel strand 6 being fixed integrally with the guardrail clamp 3.

[0033] The take-up device 5 includes a housing 501, a driven shaft 502 mounted on the side wall of the housing 501 by bearings, a winch 503 integrally mounted on the driven shaft 502 and a driven gear 504; a drive shaft 505 located below the driven shaft 502 is mounted on the side wall of the housing 501 by bearings, both ends of the drive shaft 505 extend outside the housing 501, and a drive gear 506 meshing with the driven gear 504 is fixed on the drive shaft 505;

[0034] The sleeve of the winch 503 is fixed to one end of the steel strand 6, and the other end of the steel strand 6 passes through the wire hole 7 and is fixed together with the guardrail clamp 3 located outside the housing 501.

[0035] The housing 501 is fixed to the post clamp 4 as a whole by the connector 8. In this embodiment, the steel strand 6 adopts a conventional cylindrical steel ring with threaded ends, which is locked by a steel ball with a threaded groove, so that the steel strand 6 is firmly connected to the guardrail clamp 3 and the post clamp 4, preventing the steel strand 6 from loosening and slipping during the rolling process of the corrugated steel guardrail 1. Of course, the steel strand 6 can also be fixed by a conventional rope knot. In specific implementation, the driving gear 506 is smaller than the driven gear 504, and the small gear drives the large gear to reduce speed and increase torque.

[0036] To ensure safety during use, in the above embodiment, preferably: a ratchet 9 is fixed to one end of the drive shaft 505, a pawl 10 is provided above the ratchet 9, the pawl 10 is fixed to the outer wall of the housing 501 by a pin, the pawl 10 swings along the pin under the action of external force, the pawl 10 is fixedly connected to one end of the return spring 11, and the other end of the return spring 11 is fixed to the outer wall of the housing 501;

[0037] Under normal conditions, the pawl 10 is engaged with the ratchet 9. In this embodiment, when the drive shaft 505 is rotated by external force, it can only rotate in one direction. Only after the pawl 10 is pried open from the ratchet 9 by external force can it rotate in both directions. In specific implementations, the engagement of the pawl 10 and the ratchet 9 can be set with a forward / reverse switch and a neutral switch to achieve rapid control over whether the pawl 10 and the ratchet 9 are engaged.

[0038] For ease of operation, in the above embodiment, preferably, one end of the drive shaft 505 is fixed with a rocker arm 12. In this embodiment, the rocker arm 12 can be a commercially available telescopic rocker arm, which allows workers of different heights to adjust the length to suit their own height.

[0039] To ensure the clamping and fixing of the corrugated steel guardrail, in the above embodiment, preferably: the guardrail clamp 3 includes two clamp plates 301 that match the corrugation of the corrugated steel guardrail 1. These two clamp plates 301 are fixed together by bolts. The other end of the steel strand 6 passes through the wire hole 7 and is fixed together with one of the clamp plates 301. In this embodiment, the other end of the steel strand 6 passes through the wire hole 7 and is fixed together with the connecting ring 302 fixed to the outer plate of the clamp plate 301.

[0040] To avoid damaging the anti-corrosion layer of the corrugated steel guardrail 1 during operation, in the above embodiment, preferably, a rubber pad layer is provided on the inner plate surface of the clamp plate 301.

[0041] To ensure the clamping and fixing of the column 2, in the above embodiment, preferably: the column clamp 4 includes two symmetrically arranged column clamp plates 402 with arc-shaped portions 401, and the two sides of the column clamp plates 402 have connecting plates 403.

[0042] The two column clamping plates 402 are fixed together by bolts passing through the connecting plate 403. The clamping cavity 404 enclosed by the arc-shaped part 401 on the two column clamping plates 402 matches the outer diameter of the column 2.

[0043] To avoid damaging the anti-corrosion layer of the column 2 during operation, in the above embodiment, preferably, a rubber pad layer is provided on the inner plate of the column clamp plate 402.

[0044] All components in the above embodiments are commercially available products.

[0045] The installation process of the portable installation device for the corrugated beam guardrail described in the above embodiments is as follows:

[0046] The first step is preparation.

[0047] At the construction site of the curved section, the layout of post 2, foundation construction, installation of post 2, installation of post cap, and installation of brackets are completed first. Then, one end of the straight, wavy steel guardrail panel 1 is fixed to the first installed post 2 using brackets.

[0048] The second step is the installation of the portable installation device for the corrugated beam guardrail described in this solution.

[0049] First, connect the housing 501 to the post clamp 5 via the connector 8, ensuring that the retractor 5 is securely fixed to the second post 2 adjacent to the first post 2. Then, clamp the guardrail clamp 3 onto the corrugated steel guardrail 1 at the position where it is to be pre-bent.

[0050] Step 3: Bend the wavy steel guardrail panel 1.

[0051] The construction worker rotates the rocker arm 12, causing the drive shaft 505 to rotate. The drive gear 506 on the drive shaft 505 drives the driven gear 504 above to rotate. Through the speed reduction and torque increase effect of the gear set, the winding reel 503 slowly tightens the steel strand 6. The tightening of the steel strand 6 applies tension to the corrugated steel guardrail 1, causing it to gradually bend into the desired arc shape. The speed reduction and torque increase design of the gear set makes operation labor-saving, and the corrugated steel guardrail 1 can be bent with relatively small force. During the bending process, the construction worker can observe the degree of bending of the guardrail and tighten or loosen the steel strand 6 in real time to control the degree of bending.

[0052] Step 4: Complete the installation.

[0053] Once the corrugated steel guardrail 1 is bent to match the curvature of the curved road section, the tightening of the steel strand 6 is stopped, and it is locked in place by the ratchet locking mechanism formed by the pawl 10 and the ratchet 9. The worker then fixes the corrugated steel guardrail 1 to the second post 2 to complete the installation.

[0054] Step 5: Remove the portable installation device for the corrugated beam guardrail described in this solution, and repeat steps 2 to 4 or steps 1 to 4.

[0055] The entire construction process is highly safe, avoiding the safety hazards associated with manual pulling. The curved guardrail panels have a smooth, rounded shape and aligned joints, ensuring the overall structural continuity and collision energy absorption efficiency of the corrugated beam guardrail. Through the above construction process, the structure described in this solution significantly improves the installation efficiency and quality of the corrugated beam guardrail on curved sections, while reducing the labor intensity and safety hazards for construction workers.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of this technical solution, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
