Description

Technical Field

[0001] The utility model relates to the technical field of road construction, in particular to a warning device for municipal road engineering construction. Background Art

[0002] Municipal road construction refers to the construction and maintenance of roads within a city or urban area. It involves the planning, design, construction, and management of urban infrastructure to meet people's transportation needs. Warning signs are often placed around construction sites to remind passers-by to avoid them.

[0003] When constructing a designated area, warning boards are used to surround it in a circular manner to achieve a better warning and interception effect. However, the warning boards are not connected after being surrounded, and a single warning board is very likely to fall over when exposed to strong winds. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings in the prior art, the utility model provides a warning device for municipal road engineering construction.

[0005] The technical solution is as follows: A warning device for municipal road engineering construction includes a base plate, a bracket and a warning plate. The bracket is fixedly connected to the top of the base plate symmetrically on the left and right, and the warning plate is fixedly connected between the upper parts of the two brackets. It also includes a connecting component and a support component. A connecting component for connecting multiple warning devices together is provided between the upper parts of the two brackets, and a support component is provided on the base plate for increasing the support area between it and the ground.

[0006] Furthermore, the connecting assembly includes a connecting shaft, an intercepting frame, a mounting seat, a clamping rod and an elastic member. The connecting shaft is fixedly connected to the upper rear side of the bracket on the left side, and the intercepting frame is rotatably connected to the connecting shaft. The mounting seat is fixedly connected to the upper rear side of the bracket on the right side, and the mounting seat is symmetrically slidably connected to the clamping rod up and down, and an elastic member is connected between the two clamping rods.

[0007] Furthermore, the support assembly includes a rotating shaft, an expansion plate, a positioning rod and a U-shaped card plate. The front and rear sides of the base plate are fixedly connected to the rotating shaft, and the expansion plates are rotatably connected to the two rotating shafts. Two positioning rods are fixedly connected to the right side of the base plate, and a U-shaped card plate is slidably arranged between the two positioning rods. Two insertion rods are fixedly connected to the front and rear sides of the U-shaped card plate.

[0008] Furthermore, a reflective tape is included, and the upper front sides of the two brackets are fixedly connected with the reflective tape.

[0009] Furthermore, it also includes a groove plate, the bottom of the base plate is fixedly connected to the groove plate in a left-right symmetrical manner, and the sides of the two expansion plates facing the ground are also fixedly connected to the groove plate in a left-right symmetrical manner.

[0010] Furthermore, it also includes magnetic blocks, and two magnetic blocks are fixedly connected to one side of the U-shaped card plate close to the bottom plate.

[0011] The beneficial effects of the present invention are as follows: 1. By setting a connecting component, multiple warning devices can be connected into a whole. The support component is optimally set. After the two expansion plates are unfolded, the contact area between the bottom plate and the ground can be increased, so that a single warning device is more stable, and the warning device connected as a whole can be more stable, effectively avoiding the situation of being blown down by strong winds.

[0012] 2. By setting up reflective tape, it can attract the attention of drivers and pedestrians, making them easier to be noticed and identified, thus playing a warning role. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] Example: A warning device for municipal road construction, such as Figures 1-4 As shown, it includes a base plate 1, a bracket 2 and a warning plate 3. The bracket 2 is welded and fixed symmetrically on the top of the base plate 1, and the warning plate 3 is welded and fixed between the upper parts of the two brackets 2. It also includes a connecting component and a supporting component. A connecting component for connecting multiple warning devices together is provided between the upper parts of the two brackets 2, and a supporting component for increasing the supporting area between it and the ground is provided on the base plate 1.

[0020] like Figure 3As shown, the connecting assembly includes a connecting shaft 4, an intercepting frame 5, a mounting seat 6, a clamping rod 7 and an elastic member 8. The connecting shaft 4 is welded and fixed to the upper rear side of the bracket 2 on the left side, and the intercepting frame 5 is rotatably connected to the connecting shaft 4. The mounting seat 6 is welded and fixed to the upper rear side of the bracket 2 on the right side. The mounting seat 6 is symmetrically slidably connected to the clamping rod 7 up and down. An elastic member 8 is connected between the two clamping rods 7, and the elastic member 8 is a reset spring. The intercepting frame 5 is symmetrically provided with holes up and down on the side away from the connecting shaft 4. The two clamping rods 7 can be respectively inserted into the two holes to fix and limit the intercepting frame 5.

[0021] like Figure 4 As shown, the support assembly includes a rotating shaft 9, an expansion plate 10, a positioning rod 11 and a U-shaped card plate 12. The rotating shaft 9 is welded and fixed on the front and rear sides of the base plate 1. The expansion plates 10 are rotatably connected to the two rotating shafts 9. Two positioning rods 11 are welded and fixed on the right side of the base plate 1. A U-shaped card plate 12 is slidingly arranged between the two positioning rods 11. Two insertion rods 121 are welded and fixed on the front and rear sides of the U-shaped card plate 12. A slot is opened on the right side of the two expansion plates 10 near the U-shaped card plate 12. The insertion rod 121 can be inserted into the adjacent slot to achieve a fixed limiting effect on the expansion plate 10.

[0022] When in use, first arrange multiple warning devices in sequence around the construction area, pull the two clamping rods 7 on one of the warning devices in the direction of approaching each other, thereby releasing the fixed limit of the interception frame 5, at this time the elastic member 8 is compressed, and after loosening the clamping rod 7, the two clamping rods 7 are reset in the direction of moving away from each other under the resetting action of the elastic member 8, and the interception frame 5 is turned away and connected to a warning device on the side through the cooperation of the clamping rod 7 and the jack, so that multiple warning devices are connected in sequence into a whole, so that they can maintain good warning in windy weather. To ensure stability and prevent it from being blown down by strong winds, when placing the warning device, the U-shaped card plate 12 can be removed from the positioning rod 11 first, so that the insertion rod 121 is disengaged from the card slot set on the expansion plate 10. At this time, the two expansion plates 10 can be unfolded to the same horizontal state as the base plate 1, and then the U-shaped card plate 12 is reset, so that the insertion rod 121 fixes and limits the two expansion plates 10. After the two expansion plates 10 are unfolded, the contact area between the base plate 1 and the ground can be increased, so that a single warning device is more stable, thereby making the warning device connected as a whole more stable.

[0023] like Figure 2 As shown, a reflective tape 13 is also included, and the reflective tape 13 is bonded and fixed to the upper front sides of the two brackets 2.

[0024] By setting up the reflective tape 13, the reflective tape 13 utilizes the principle of optical reflection. When light (such as car lights, street lights, etc.) shines on its surface, the light will be reflected back in the direction of the light source to form a bright light spot. This reflective effect is particularly significant at night or in low visibility conditions, and can effectively improve the visibility of the warning device.

[0025] like Figure 1 As shown, it also includes a groove plate 14. The groove plate 14 is symmetrically bonded and fixed to the bottom of the base plate 1, and the groove plates 14 are also symmetrically bonded and fixed to the sides of the two expansion plates 10 facing the ground.

[0026] By providing the groove plate 14 , the friction between the base plate 1 and the expansion plate 10 and the ground can be increased, so that the warning device can be placed on the ground more stably.

[0027] like Figure 4 As shown, it also includes a magnetic block 15 , and two magnetic blocks 15 are welded and fixed on one side of the U-shaped clamping plate 12 close to the bottom plate 1 .

[0028] By providing the magnetic block 15 , when the U-shaped card plate 12 is clamped on the positioning rod 11 to position the expansion board 10 , the U-shaped card plate 12 can be magnetically connected to the base plate 1 through the magnetic block 15 , thus preventing the U-shaped card plate 12 from loosening.

Their purpose is to enable those familiar with the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications based on the spirit of the present invention are intended to be included in the scope of protection of the present invention.
