Description

Technical Field

[0001] The utility model relates to the technical field of warning bars, in particular to a warning bar with a wide effective range. Background Art

[0002] In cities, all public water supplies, sewage drains, telephone lines, and fiber optic networks may be connected through underground passages under manholes. As ancillary facilities of buildings, manholes need to be built during the construction process on site to facilitate the basic water supply, power supply, and drainage needs of subsequent residents.

[0003] The document with prior art publication number CN218843941U provides an assembled warning barrier, which is used in conjunction with a cover plate, a water filling tank, a counterweight box and a faucet. After the device is moved to the desired position, the cover plate is opened and water is filled into the device through the water filling tank. The use of the counterweight box increases the capacity of the device, further increases the amount of water in the device, and increases its stability. When the device is used, the faucet is opened to release the water inside the device, thereby reducing its weight and facilitating movement.

[0004] Although the device has many beneficial effects, the following problems still exist: during the construction process, there are many vehicles coming and going on the site, especially concrete pump trucks used to transport concrete. Their weight is heavy, which can easily cause the manhole covers on the roads inside the construction site to be crushed and damaged. When the manhole covers on the roadside in the construction site are damaged, the above-mentioned warning bar is difficult to effectively fence the manhole opening, which can easily cause construction workers and vehicles on the site to fall into the manhole, thereby making the applicable scenarios of the warning bar narrower. In view of this, we propose a warning bar with a wide effective range. Utility Model Content

[0005] In view of the above technical problems, the utility model provides a warning bar with a wide effective range.

[0006] The technical solution includes: a warning guardrail,

[0007] A barrier mechanism is provided on both sides of the warning guardrail, each of the barrier mechanisms comprises a first barrier rotatably connected to the warning guardrail, a placement cavity is provided on the side of the first barrier away from the warning guardrail, a second barrier is slidably connected in the placement cavity, a slot is provided through the top of the first barrier, a slide is fixedly connected to one side of the top of the second barrier, and the slide slides in the slot;

[0008] A support plate is fixedly connected to one end of the top of the first enclosure close to the warning guardrail, a threaded rod is threadedly connected to the support plate, and one end of the threaded rod is rotatably connected to a slide plate.

[0009] Preferably, both the top and bottom sides of the warning guardrail are rotatably connected to rotating rods, and the first enclosure is fixedly connected to the rotating rods.

[0010] Preferably, damping bearings are provided on both sides of the top and bottom of the warning guardrail, and one end of the rotating rod is located in the damping bearing.

[0011] Preferably, both ends of the bottom of the warning guardrail are fixedly connected to a supporting leg.

[0012] Preferably, a knob is coaxially fixedly arranged at one end of the threaded rod away from the slide plate.

[0013] The beneficial effects brought about by the technical solution provided by the embodiment of the utility model are: 1. By setting up a fencing mechanism, when there is damage on the roadside manhole cover inside the construction site, the manhole cover can be fenced and warned to prevent construction workers and vehicles from falling into the manhole, thereby expanding the applicable scenarios of the warning bar.

[0014] 2. By setting up the second enclosure, it is convenient to pull a part of the second enclosure out of the placement cavity, so that when the manhole opening is at a certain distance from the curbstone, the manhole opening can be fully enclosed.

[0015] 3. By setting a threaded rod, the slide plate can be moved when the threaded rod is twisted. When the threaded rod is not twisted, the slide plate will not move at will, thereby preventing the second enclosure from moving at will. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example 1

[0024] See also Figure 1 to Figure 2 The utility model provides a warning fence with a wide effective range, including a warning guardrail 1,

[0025] A blocking mechanism 3 is provided on both sides of the warning guardrail 1, so as to facilitate the blocking and warning of the manholes on the roadside inside the construction site, and broaden its application scenarios;

[0026] Each enclosure mechanism 3 includes a first enclosure 31 rotatably connected to the warning guardrail 1, a placement cavity is provided on the side of the first enclosure 31 away from the warning guardrail 1, a second enclosure 8 is slidably connected in the placement cavity, a slot 4 is provided through the top of the first enclosure 31, a slide plate 6 is fixedly connected to one side of the top of the second enclosure 8, and the slide plate 6 slides in the slot 4;

[0027] The warning guardrail 1, the first enclosure 31, and the second enclosure 8 are all in a rectangular frame structure, and a plurality of connecting rods are arranged in the rectangular frame for fixed connection;

[0028] The second enclosure 8 is in contact with the curbstone inside the construction site when in use, thereby fully enclosing the manhole opening and improving the warning effect;

[0029] The bottom of the inner wall of the placement cavity is opened, and a slider is slidably connected in the slide groove, and the slider is fixedly connected to the bottom of the second enclosure 8, so as to facilitate the guidance of the movement of the second enclosure 8;

[0030] The height of the slide plate 6 is higher than the inner wall height of the slot 4, so that it is convenient for the staff to pull the slide plate 6 to drive the second enclosure 8 to move;

[0031] A support plate 5 is fixedly connected to one end of the top of the first enclosure 31 close to the warning guardrail, and a threaded rod 7 is threadedly connected to the support plate 5 , and one end of the threaded rod 7 is rotatably connected to the slide plate 6 .

[0032] The top and bottom sides of the warning guardrail 1 are rotatably connected with a rotating rod 32, and the first enclosure 31 is fixedly connected to the rotating rod 32.

[0033] This makes it easy to rotate the first enclosure 31 with the rotating rod 32 as the axis, so as to facilitate enclosure warning of the manhole opening on the roadside inside the construction site.

[0034] Damping bearings 33 are provided on both sides of the top and bottom of the warning guardrail 1. One end of the rotating rod 32 is located in the damping bearing 33. The damping bearing 33 can prevent the first enclosure 31 from rotating at will.

[0035] A supporting leg 2 is fixedly connected to both ends of the bottom of the warning guardrail 1, so as to facilitate stable support of the warning guardrail 1.

[0036] A knob is coaxially fixedly arranged at one end of the threaded rod away from the slide plate 6, and anti-skid grooves are arranged on the outer side of the knob, so as to increase the friction between the hand of the staff and the knob.

[0037] When the utility model is used, when it is necessary to fence off and warn the manhole opening, the first fence 31 can be rotated, and the first fence 31 can drive the rotating rod 32 to rotate, so that the first fence 31 is changed from a parallel state with the warning guardrail 1 to a perpendicular state to each other, and then the threaded rod 7 is twisted. When the threaded rod 7 is twisted, it can drive the slide plate 6 to move, and the movement of the slide plate 6 can drive the second fence 8 to move, so that the second fence 8 moves a certain length out of the placement cavity, so that the second fence 8 contacts the curbstone in the construction site, so that the manhole opening can be fully fenced, thereby broadening the applicable scenarios of the warning fence.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
