Description

Technical Field

[0001] This utility model relates to the field of construction warning technology, specifically a construction safety warning device for highway maintenance. Background Technology

[0002] Highway maintenance is a crucial aspect of ensuring smooth and safe traffic flow, encompassing the upkeep and maintenance of roads. Maintenance focuses on the entire process from the moment a highway is built and opened to traffic, while repair focuses on restoring damaged sections. Due to the large number of vehicles traveling on highways, effective warning devices must be installed during maintenance to alert vehicles and pedestrians and prevent traffic accidents.

[0003] With the widespread use of smartphones, more and more pedestrians are becoming "smartphone addicts," often focusing on their phone screens while walking and ignoring surrounding safety warnings. Existing warning devices lack the function of interception, and there is a lack of effective protective measures for these pedestrians. As a result, pedestrians often accidentally enter construction sites. Therefore, a construction safety warning device for highway maintenance is proposed to solve the above problems.

[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] Example 1, as Figures 1-5 As shown, a construction safety warning device for highway maintenance includes an I-shaped frame 1 and four No. 1 sliding wheels 101 fixedly installed at the bottom of the I-shaped frame 1. The top of the I-shaped frame 1 is provided with a barrier structure, the top of the barrier structure is provided with a warning structure, and the bottom of the I-shaped frame 1 is provided with a stable support structure.

[0027] Specifically, the barrier structure includes a column 2 fixedly installed on the top of the I-beam frame 1, a top plate 3 fixedly installed on the top of the column 2, two storage slots 4 opened at the bottom of the top plate 3, the two storage slots 4 respectively extending to the left and right sides of the top plate 3, folding fences 5 are provided on both the left and right sides of the column 2, and side plates 6 are provided on the outer side of the two folding fences 5, the two side plates 6 being located inside the two storage slots 4 and the I-beam frame 1 respectively.

[0028] Specifically, the warning structure includes four strobe lights 7 fixedly installed on the surfaces of the two side panels 6, an L-shaped base 8 fixedly installed on the top of the top panel 3, a cross-shaped fixing bracket 9 fixedly installed on the surface of the L-shaped base 8 near its top, an LED warning sign 10 set on the surface of the cross-shaped fixing bracket 9, and four hand-tightening bolts 11 threaded through the LED warning sign 10 on the back of the cross-shaped fixing bracket 9.

[0029] The barrier and warning structures are supported by the I-beam frame 1. Four No. 1 sliding wheels 101 slide on the ground, facilitating the transfer of the device. By manipulating the two side plates 6 to move to the left and right, the two folding fences 5 can be pulled open. After the folding fences 5 on the left and right sides of the column 2 are unfolded, the construction site can be isolated, effectively preventing pedestrians from accidentally entering the construction site. At this time, the flashing lights 7 installed on the surface of the two side plates 6 will flash, which can warn vehicles and pedestrians around the construction site at night. The cross fixing frame 9 and LED warning sign 10 can be supported on the top of the top plate 3 by the L-shaped base frame 8. At this time, the LED warning sign 10 will light up to remind surrounding vehicles and pedestrians that the area is a construction area. When the device is not in use, by manipulating the four hand-tightening bolts 11 to rotate in the opposite direction, the LED warning sign 10 can be detached from the cross fixing frame 9, which makes it easier to store the LED warning sign 10, prevents dust from falling on it, and reduces the probability of damage to the LED warning sign 10.

[0030] Example 2, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0031] The stable support structure includes a support base plate 12 located below the I-beam frame 1. Four limiting rods 13 are fixedly installed on the top of the support base plate 12. All four limiting rods 13 are slidably installed inside the I-beam frame 1. A threaded rod 14 is threaded through the top of the I-beam frame 1 and extends to its bottom. The threaded rod 14 is rotatably installed on the top of the support base plate 12.

[0032] With this configuration, the support base plate 12 is restricted to the bottom of the I-beam frame 1 by four limit rods 13. By controlling the threaded rod 14 to rotate in the forward direction, the support base plate 12 can be lowered. When the support base plate 12 contacts the ground, the device can be stably supported on the ground. By controlling the storage slot 4 to rotate in the reverse direction, the support base plate 12 can be raised.

[0033] Example 3, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0034] A plug-in plate 15 is fixedly installed on the surface of the column 2. The two side plates 6 are provided with plug-in interfaces 16. The plug-in plate 15 extends through the interior of the two plug-in interfaces 16. Rotating blocks 17 located on the outer side of the side plate 6 are rotatably installed on both the left and right sides of the plug-in plate 15.

[0035] With this setup, pushing the two side plates 6 closer to the column 2 can push the two folding fences 5 to fold. At this time, the plug plate 15 is inside the two plug interfaces 16. Then, by controlling the two rotating blocks 17 to rotate 90 degrees, the two side plates 6 can be limited respectively, preventing the folding fences 5 and side plates 6 from automatically unfolding when the device is operated.

[0036] Example 4, as Figures 2-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0037] The back of the LED warning sign 10 is fixedly equipped with four arc plates 18, which are located on the outer sides of the four top ends of the cross fixing frame 9.

[0038] With this setup, when installing the LED warning sign 10, the four arc plates 18 are placed over the four top ends of the cross bracket 9. At this time, the threaded holes on the back of the LED warning sign 10 correspond to the threaded holes of the cross bracket 9, making it convenient to connect the hand-tightened bolts 11 with the LED warning sign 10 for installation.

[0039] Example 5, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0040] Multiple guide rails 19 are fixedly installed on the front and rear walls of the two storage slots 4 and inside the I-shaped frame 1. The two side plates 6 are slidably engaged with the multiple guide rails 19 respectively.

[0041] This configuration, with multiple guide rails 19, restricts the two side panels 6 to slide within the two storage slots 4 and the I-shaped frame 1, preventing displacement and swaying when the folding fence 5 and side panels 6 are folded up.

[0042] Example 6, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0043] The bottom of both side plates 6 is fixedly equipped with pulleys 20 of the second type, which are on the same plane as pulley 101 of the first type.

[0044] This configuration allows the two side plates 6 to be supported and slid by the two pulleys 20, making it easy to pull the two side plates 6 outwards.

[0045] Example 7, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0046] The support base plate 12 is located inside the four No. 1 sliding wheels 101.

[0047] This design prevents the four No. 1 sliding wheels 101 from colliding with the support base plate 12 during movement.

[0048] Example 8, as Figures 1-3 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0049] A hand-cranked turntable is fixedly installed on the top of the threaded rod 14, and the hand-cranked turntable is located in front of the column 2.

[0050] This configuration allows for easy control of the forward and reverse rotation of the threaded rod 14 via a hand crank.

[0051] Working principle:

[0052] The device is supported by an I-beam frame 1, with four No. 1 sliding wheels 101 fixed at its bottom, allowing the entire device to slide easily on the ground and be moved between different construction areas. The top of the I-beam frame 1 features a barrier structure, including columns 2, a top plate 3, storage slots 4, folding fences 5, and side plates 6. Columns 2 are fixed to the top of the I-beam frame 1, and the top plate 3 is located at the top of the columns 2, with two storage slots 4 for storing the folded fences 5 and side plates 6. When it is necessary to isolate the construction site, the folding fence 5 can be unfolded by manipulating the two side plates 6 to the left and right, effectively preventing pedestrians from accidentally entering the construction site. Simultaneously, flashing lights 7 installed on the surface of the side plates 6 emit a flashing light at night, further warning vehicles and pedestrians around the construction site.

[0053] The warning structure is located on top of the barrier structure and includes an L-shaped base frame 8, a cross-shaped fixing frame 9, an LED warning sign 10, and hand-tightening bolts 11. The L-shaped base frame 8 is fixed to the top of the top plate 3, supporting the cross-shaped fixing frame 9 and the LED warning sign 10. When the LED warning sign 10 is lit, it can clearly remind surrounding vehicles and pedestrians that the area is a construction area. When the device is not in use, the LED warning sign 10 can be easily separated from the cross-shaped fixing frame 9 by rotating the four hand-tightening bolts 11 in the opposite direction, which is convenient for storing the LED warning sign 10 and preventing dust and damage. It is worth noting that the four arc plates 18 installed on the back of the LED warning sign 10 can be fitted onto the four top ends of the cross-shaped fixing frame 9 during installation, so that the threaded holes on the back of the LED warning sign 10 correspond to the threaded holes of the cross-shaped fixing frame 9, which facilitates the mating installation of the hand-tightening bolts 11.

[0054] In addition, the device is designed with a stable support structure, including a support base plate 12, limiting rods 13, and threaded rods 14. The support base plate 12 is located below the I-beam frame 1 and is slidably installed inside the I-beam frame 1 by the four limiting rods 13. When the device needs to be stabilized, the threaded rods 14 are rotated in the forward direction, causing the support base plate 12 to descend and contact the ground, thereby stabilizing the entire device on the ground. In order to prevent the four No. 1 sliding wheels 101 from colliding with the support base plate 12 during movement, the support base plate 12 is designed to be located inside the four No. 1 sliding wheels 101. The hand crank installed on the top of the threaded rods 14 makes it easy to control the forward and reverse rotation of the threaded rods 14, thereby adjusting the height of the support base plate 12.

[0055] When folding the folding fence 5 and side panels 6, multiple guide rails 19 respectively restrict the two side panels 6 to slide inside the two storage slots 4 and the I-shaped frame 1, preventing displacement and shaking when folding the folding fence 5 and side panels 6. At the same time, the second pulley 20 installed at the bottom of the two side panels 6 is on the same plane as the first sliding wheel 101, which makes it easy to pull the two side panels 6 outward. When the folding fence 5 is folded, the plug plate 15 will penetrate into the plug interface 16 of the two side panels 6. At this time, by operating the two rotating blocks 17 to rotate 90 degrees, the two side panels 6 can be limited respectively, preventing the folding fence 5 and side panels 6 from automatically unfolding when the device is running.

[0056] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
