Description

Technical Field

[0001] The utility model relates to the technical field of road barriers, in particular to a temporary road barrier device for municipal engineering. Background Technique

[0002] Road barriers refer to various obstacles set on roads to restrict, separate or warn traffic. Road barriers are usually made of different materials, such as plastics, rubbers, metals, etc. In road construction areas, road barriers can isolate the construction area from the normal driving road, ensuring the safety of construction personnel, and at the same time reminding passing vehicles and pedestrians to pay attention to detouring.

[0003] For example, a traffic temporary blocking device disclosed in Chinese patent literature (Publication No.: CN220847250U), although this utility model is convenient for installation and disassembly, can adjust the length of the road barrier rod according to the width of the road, and the warning light can improve the warning effect and can play a role in warning pedestrians.

[0004] However, this device is not convenient to move. When moving a short distance, using a vehicle to tow it is too wasteful of human and material resources, and using manual handling has low efficiency. Moreover, this device needs to be assembled on site during use, which is rather troublesome.

[0005] Therefore, we propose a temporary road barrier device for municipal engineering. Content of the Utility Model

[0027] Embodiment 1

[0028] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: It includes a moving base 1. The upper surface of the moving base 1 is fixedly connected with an installation housing 2. Both inner walls of the installation housing 2 are installed with a bidirectional threaded rod 3 through bearings. The outer surface of the bidirectional threaded rod 3 is fixedly sleeved with a turbine 4. The front inner wall of the installation housing 2 is installed with a worm 5 through a bearing. The tooth surface of the worm 5 meshes with the tooth surface of the turbine 4. One end of the worm 5 penetrates and extends to the front of the installation housing 2. One end of the worm 5 is fixedly connected with a turntable 6. The inner bottom wall and the inner top wall of the installation housing 2 are provided with symmetrically distributed limiting sliding grooves 7;

[0029] The outer surface of the bidirectional threaded rod 3 is threadedly sleeved with symmetrically distributed moving plates 8. The two ends of the moving plates 8 are respectively slidably connected with the inner walls of the two limiting sliding grooves 7. The rotation of the turntable 6 drives the turbine 4 to rotate through the worm 5. With the cooperation of the limiting sliding grooves 7, the two moving plates 8 move away from each other, thereby driving the square tube 10 to unfold from the inside of the installation housing 2 to adapt to the width of the road to be blocked.

[0030] Embodiment 2

[0031] As Figures 1-4 shown in the figure, the present utility model provides a technical solution: Square holes 9 are provided on both side surfaces of the installation housing 2. Multiple square holes 9 are grouped in twos and are symmetrically distributed. Symmetrically distributed square tubes 10 are fixedly connected to one side surface of the moving plates 8.

[0032] The outer surface of the square tube 10 is slidably sleeved with the inner wall of the square hole 9. A linearly arrayed receiving groove 11 is provided on the lower surface of one of the square tubes 10. When the device is not in use, the magnetic attraction block 15 is located in the receiving groove 11.

[0033] The inner top wall of the receiving groove 11 is provided with square access holes 12. One end of each of the multiple square access holes 12 penetrates and extends to the inner bottom wall of one of the square tubes 10.

[0034] A linearly arrayed telescopic wire winding device 13 is installed on the inner top wall of one of the square tubes 10 through a mounting block. The telescopic wire winding device 13 can automatically contract and extend the reflective strip 14 stored inside it, which is composed of an outer shell, a wire winding shaft, a spring, a ratchet mechanism, etc. When the wire is pulled out, the spring is stretched and stores elastic potential energy. When the external force disappears, the elastic potential energy of the spring is released, prompting the wire winding shaft to rotate and retract the wire. The telescopic wire winding device 13 is internally wound and connected with the reflective strip 14. One end of the reflective strip 14 penetrates the square access hole 12 and extends to the lower surface of one of the square tubes 10.

[0035] One end of the reflective strip 14 is fixedly connected with a magnetic attraction block 15. Magnetism attracting grooves 16 are provided on the upper surface of the other square tube 10 in a linearly arrayed manner.

[0036] The inner wall of the magnetic attraction groove 16 and the outer surface of the magnetic attraction block 15 are magnetically attracted to each other, and the suction force between the two can prevent the telescopic wire winding device 13 from retracting the reflective strip 14. An audible and visual alarm 17 is fixedly installed on the upper surface of the installation housing 2, and an infrared sensor 18 is fixedly installed on the front surface of the installation housing 2. When a pedestrian enters the detection range of the infrared sensor 18, the audible and visual alarm 17 emits an alarm to remind the pedestrian to leave and can also remind the staff that someone is approaching. The front surface of the installation housing 2 is fixedly connected with reflective stickers 19 distributed in a linear array.

[0037] The setting of the mobile base enables the device to be moved short distances conveniently and quickly. Moreover, through the setting of the turbine and worm, when using this device, only the turntable needs to be rotated to adjust according to the road width, without the need for on-site assembly, making it extremely convenient to use. Furthermore, the settings of the infrared sensor and the audible and visual alarm can remind pedestrians to leave and remind the staff that someone is approaching when a pedestrian approaches.

[0038] The working process of the present utility model:

[0039] Step 1, when the device is not in use, the reflective strip 14 is inside the telescopic wire winding device 13, the magnetic attraction block 15 is inside the storage groove 11, and the square tube 10 is inside the installation housing 2 and is not unfolded, which is convenient for storage and transportation. When the device needs to be used, the device is quickly moved to the usage location through the mobile base 1. According to the width of the on-site road, the device can be adjusted. Rotate the turntable 6, and the rotation of the turntable 6 drives the turbine 4 to rotate through the worm 5. With the cooperation of the limit sliding groove 7, the two moving plates 8 move away from each other, thereby driving the square tube 10 to unfold from inside the installation housing 2 to adapt to the width of the road to be blocked.

[0040] Step 2, after the square tube 10 is unfolded to the corresponding width, pull the magnetic attraction block 15 one by one to drive the reflective strip to extend out of the telescopic wire winding device 13 until the magnetic attraction block 15 is placed inside the magnetic attraction groove 16. Due to the magnetic force, the magnetic attraction block 15 is fixed by the magnetic attraction groove 16 to prevent the telescopic wire winding device 13 from sucking the reflective strip 14 back into it. At this time, the device has been adjusted according to the road width. The settings of the reflective strip 14 and the reflective stickers 19 enable the device to still prevent passers-by from entering the blocked area at night. Moreover, when a pedestrian enters the detection range of the infrared sensor 18, the audible and visual alarm 17 emits an alarm to remind the pedestrian to leave and can also remind the staff that someone is approaching.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
