Description

Technical Field

[0001] This utility model relates to the field of road sign fixing technology, and more specifically, to a fixator for temporarily fixing traffic sign poles. Background Technology

[0002] The "Safety Operation Procedures for Highway Maintenance" (JTG H30-2015) are the relevant requirements that must be followed in the safety control of highway maintenance and construction operations. Currently, the installation procedure for temporary traffic warning signs, which are widely used on construction sites, is generally as follows: one construction worker must hold up the traffic warning sign post, and another construction worker must tie the traffic sign post to the corrugated guardrail post to fix the traffic sign in place. During this process, wire is used to tie and fix it to the corrugated guardrail post.

[0003] The following shortcomings exist in this connection method: (1) High risk factor: When the traffic sign post is fixed by binding wire, there is uneven force, which can easily loosen and overturn, leading to traffic accidents and endangering driving safety. (2) High labor cost: Two workers have to lift the pole and tie the wire, which is complicated and the operation time is continuously extended, which seriously increases the labor and time costs.

[0014] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] Please see Figures 1-4 This utility model provides a technical solution: A fixation device for temporarily fixing traffic sign poles is used to fix them to guardrail 101. The fixation device includes a first fixing mechanism detachably connected to guardrail 101 and a second fixing mechanism installed on the first fixing mechanism. The second fixing mechanism is used to quickly fix the traffic sign pole 201.

[0016] Preferably, in this embodiment, the first fixing mechanism includes a vertical arm 301, an upper clamping plate 302 installed at one end of the vertical arm 301, an adjustment mechanism installed on the vertical arm 301, and a lower clamping plate 303 installed at the execution end of the adjustment mechanism. The adjustment mechanism is used to adjust the distance between the lower clamping plate 303 and the upper clamping plate 302; the second fixing mechanism is installed on the vertical arm 301.

[0017] Specifically, refer to Figures 2-4 In this embodiment, the vertical arm 301 is a square tube with a top and a bottom. The upper clamping plate 302 is installed at the top of the vertical arm 301. The adjustment mechanism includes an adjusting bolt 304 threadedly connected to the top of the vertical arm 301, and an adjusting square tube 305 slidably installed inside the vertical arm 301. One end of the adjusting bolt 304 extends into the vertical arm 301 and is threadedly connected to the adjusting square tube 305. The end of the adjusting square tube 305 away from the adjusting bolt 304 extends out of the bottom of the vertical arm 301. The lower clamping plate 303 is installed at the end of the adjusting square tube 305 located outside the vertical arm 301. The central axis of the adjusting square tube 305, the sliding direction of the adjusting square tube 305, and the central axis of the adjusting bolt 304 are all parallel to the central axis of the vertical arm 301. In this embodiment, the cross-sections of the upper clamping plate 302 and the lower clamping plate 303 are both L-shaped to facilitate clamping.

[0018] like Figure 4 As shown, in order to facilitate the smooth up-and-down movement of the adjusting square tube 305 under the control of the adjusting bolt 304, in this embodiment, after the adjusting square tube 305 is installed inside the vertical arm 301, the distance between the outer wall of the adjusting square tube 305 and the inner wall of the vertical arm 301 is small, or the outer wall of the adjusting square tube 305 is in contact with the inner wall of the vertical arm 301, so that the adjusting square tube 305 will not rotate during the up-and-down movement inside the vertical arm 301.

[0019] Specifically, refer to Figures 2-4In this embodiment, the second fixing mechanism includes a ring 401 mounted on the vertical arm 301 and a fixing bolt 402 passing through the ring 401. The fixing bolt 402 is threadedly connected to the ring 401. The central axis of the ring 401 is parallel to the central axis of the vertical arm 301.

[0020] Preferably, in this embodiment, the ring 401 is threaded with two fixing bolts 402.

[0021] In this embodiment, to further enhance the fixing effect of the second fixing mechanism, when the thickness of the ring 401 is relatively small, the adjusting square tube 305 is also equipped with the aforementioned second fixing mechanism at one end located outside the vertical arm 301.

[0022] After the traffic sign pole 201 is temporarily fixed to the guardrail 101 using this fastener, a warning light 501 is also installed on the upper clamp 302 in this embodiment to increase the warning effect on passing vehicles.

[0023] This fixing device can be operated by a single worker wearing gloves, without the need for drills, wrenches, or other similar tools. Compared to traditional methods, the installation time for a single sign is reduced from 5 minutes for 2-3 people to just 25 seconds for a single person, decreasing the worker's exposure time in traffic by 97%. This fixing device not only significantly reduces safety risks but also strictly adheres to the core requirement of "reducing personnel exposure time" in the "Highway Maintenance Safety Operation Regulations" (JTG H30-2015).

[0024] Working principle: from Figure 2 / Figure 3 / Figure 4 From the perspective of [unclear], during installation, the vertical arm 301 can be fixed to the guardrail plate 101 first. By tightening the adjusting bolt 304, the upper clamping plate 302 and the lower clamping plate 303 can be simultaneously clamped onto the guardrail plate 101 to complete the installation. Then, the traffic sign pole 201 is inserted into the ring 401, and the fixing bolt 402 is tightened so that one end of the fixing bolt 402 is pressed against the traffic sign pole 201, thus completing the fixing of the traffic sign pole 201.

[0025] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
