Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated beam steel guardrail construction, in particular to a corrugated beam steel guardrail installation mechanism. Background Art

[0002] With the continuous development of social economy, more and more cars are appearing on the road, and traffic accidents are also increasing. Faced with such an increasingly serious situation, enhancing road driving safety is of paramount importance. Expressways are major traffic roads and places where accidents occur more frequently. When a rear-end collision, collision or a car part has problems and runs out of control out of the lane, the importance of guardrails on both sides of the road is self-evident. When a vehicle travels too fast on the highway and an accident occurs, the impact energy is absorbed by the corrugated steel guardrail to meet the energy released by the vehicle collision, thereby reducing the severity of vehicle and personnel casualties.

[0003] Some of the corrugated steel guardrails are prefabricated into curved shapes before leaving the factory, but most of the curved shapes are relatively uniform, which makes it difficult to meet the needs of curved sections with different curvature radii. Therefore, in the construction of highway safety guardrails, it is often necessary to bend the corrugated steel guardrails on site according to needs.

[0004] Currently, when installing corrugated beam steel guardrails on columns on curved road sections, a pulling device or manual pressure is used to bend the corrugated beam steel guardrail so that it is completely close to the column and fixed by bolts or the like. However, it is still difficult to completely achieve a tight fit through this pulling device. The two adjacent corrugated beam steel guardrails are still loose or misaligned, making it difficult to align the two corrugated beam steel guardrails for installation, resulting in low installation efficiency.

[0027] Example

[0028] like Figures 1 to 6 As shown, a corrugated steel guardrail installation mechanism includes a fixing component and a clamping component. The fixing component and the column 2 are detachably connected. The clamping component includes a slide bar 53 and a clamping block 9 slidably arranged on the slide bar 53. The clamping block 9 is provided with a plurality of clamping parts. The clamping parts are provided with a card slot 91 with the same profile as the corrugated steel guardrail 1. It also includes a driving mechanism, which is used to drive the clamping block 9 to move and clamp the corrugated steel guardrail 1. This structure can conveniently and quickly fit two adjacent corrugated steel guardrails 1 together, and can be installed with effort, especially for curved sections, so that two corrugated steel guardrails 1 can be aligned and installed with little effort, which saves time and effort and further improves the installation efficiency.

[0029] like Figure 1 , Figure 2 As shown, the corrugated steel guardrail 1 is configured in a wave shape, and a plurality of connection holes 11 are provided at both ends of the corrugated steel guardrail 1 to facilitate the end-to-end connection of two corrugated steel guardrails 1. Figure 3 As shown, a column 2 is arranged along the road, and a cover 21 is arranged at the upper end of the column 2. A fixing block 22 is welded on the upper side of the column 2, and a corrugated connecting block 3 is integrally extended from the side of the fixing block 22, that is, the shape of the connecting block 3 is the same as the appearance of the corrugated steel guardrail 1, and two corrugated steel guardrails 1 are closely arranged on the outer wall of the connecting block 3, and the two corrugated steel guardrails 1 and the connecting block 3 are fastened by four fixing bolts 4 to facilitate the limited and fixed connection. It is equivalent to setting a fixing bolt 4 on each protruding part / recessed part of the corrugated steel guardrail 1 to achieve a stable and firm connection.

[0030] like Figure 4-6 As shown, as a preferred embodiment of the present invention, the driving mechanism includes a nut 6, an external thread is arranged on the slide bar 53, the nut 6 and the slide bar 53 are threadedly connected, and the nut 6 is arranged close to the side wall of the pressing block 9. By rotating the nut 6, the pressing block 9 is controlled to slide and press the corrugated steel guardrail 1, and after pressing, the fixing bolt 4 is inserted to fix it.

[0031] Furthermore, a nut 2 7 is threadedly connected to the slide bar 53, a notch is provided inside the pressure block 9, and the nut 2 7 is set in the notch inside the pressure block 9, and a spring 8 is sleeved on the slide bar 53 between the pressure block 9 and the nut 2 7. Such a design can prevent the pressure block 9 from being separated from the slide bar 53. When the nut 1 6 is rotated to make the pressure block 9 press the corrugated steel guardrail 1, the spring 8 is compressed; when the corrugated steel guardrail 1 and the connecting hole 11 are fixed by the fixing bolt 4, the nut 1 6 is loosened, and the elastic force of the spring 8 makes the pressure block 9 move away from the corrugated steel guardrail 1, and the crimping state is automatically released, and the installation mechanism can be removed from the column 2.

[0032] Furthermore, the pressing block 9 is connected to the protruding portion of the corrugated steel guardrail 1 through the slot 91 ( Figure 5 The left side of the corrugated steel guardrail 1), the slide bar 53 is arranged opposite to the concave portion of the corrugated steel guardrail 1 ( Figure 5 The right side of the corrugated steel guardrail 1). Such a design can be clamped according to the shape of the corrugated steel guardrail 1, and the clamping is stable, firm, convenient and fast.

[0033] Furthermore, the corrugated steel guardrail 1 has two protrusions, each of which has two connection holes 11 symmetrically arranged, and the connection holes 11 and the slots 91 of the pressing block 9 are staggered. Figure 5The fixing bolts 4 are respectively arranged on both sides of the crimping part of the pressing block 9, that is, the existence of the pressing block 9 will not interfere with or affect the fixing bolts 4 from passing through the connecting hole 11 for fixing. There is enough space for the installation of the fixing bolts 4, and the operation is convenient and quick.

[0034] like Figure 5 As shown, the fixing assembly includes an L-shaped connecting rod 5, one end of the connecting rod 5 is provided with a positioning rod 52, the other end of the connecting rod 5 is connected to a sliding rod 53, a limiting ring 51 is provided on the positioning rod 52, and the positioning rod 52 is clamped in the inner groove 23 of the column 2.

[0035] like Figure 6 As shown, the inner wall of the pressing block 9 is provided with an annular buffer pad 92, and the inner wall of the buffer pad 92 is arranged close to the outer wall of the slide rod 53. Such a design can prevent the inner wall of the pressing block 9 from directly contacting the threaded section of the slide rod 53, causing thread damage.

[0036] like Figure 7 As shown, further, a guide rod 55 is provided on the outer wall of the pressing block 9, and a guide hole 54 is provided on the connecting rod 5, and the guide rod 55 is slidably arranged in the guide hole 54. Through the guide limit of the guide rod 55, the precise sliding positioning of the pressing block 9 can be achieved, and the wear of the buffer pad 92 can be reduced.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
