Description

Technical Field

[0001] The utility model relates to a safety warning device for municipal engineering construction, in particular to a safety warning device for municipal engineering construction. Background Technique

[0002] Municipal engineering construction refers to a series of work for the construction, maintenance and transformation of urban infrastructure during the urban construction planning process. These works include road construction, urban greening, water supply system, drainage and sewage treatment, etc. In the above maintenance work, most are small-area maintenance. After the work is completed, the repaired area is enclosed with a warning device.

[0003] During the installation of the existing warning device, multiple independent devices are required to enclose the maintenance position, or some cylinders are fixed first, and then the warning paper tape is wound around the cylinders to finally form a relatively small warning area. The above warning device is complex to use and inconvenient to store, cannot be quickly unfolded, and wastes the working time of the staff.

[0004] In order to solve the above technical problems, we designed a safety warning device that can be quickly unfolded. Content of the Utility Model

[0005] In order to overcome the disadvantages of complex use and inconvenient storage, the technical problem of the utility model is: to provide a safety warning device that can be quickly unfolded.

[0006] A safety warning device for municipal engineering construction is characterized in that: it includes a column, the column is fixed on the ground, a vertically arranged rotating shaft is rotatably connected to the column, a large torsion spring is fixedly connected between the rotating shaft and the column, a soft cover is fixedly connected between the rotating shaft and the column, the soft cover is located outside the large torsion spring, a vertically arranged limiting frame is fixedly connected to the inner wall of the column, a soft rope is fixedly connected to the rotating shaft, and the soft rope passes through the limiting frame far away.

[0007] Further explanation, a handle is fixedly connected to one side of the column close to the limiting frame. When the staff installs it, pull the handle to open the column around.

[0008] Further explanation, it also includes a hollow column, the hollow column is fixedly connected to the top of the column, a rotating plate is rotatably connected to one side of the hollow column far away from the limiting frame, a small torsion spring is fixedly connected between the rotating plate and the hollow column, a large air cylinder is fixedly connected to the upper end of the column, the output shaft of the large air cylinder is fixedly connected with a flashing light, and an arc-shaped frame is fixedly connected to the flashing light.

[0009] Further explanation, it also includes a column, a fixing plate is fixedly connected to one side of the column far away from the hollow column, a rotating frame is rotatably connected to one side of the fixing plate close to the hollow column, a fixing rod is fixedly connected to one side of the fixing plate close to the hollow column, a folding plate is rotatably connected to the fixing rod, and a plug rod frame is slidably connected to one side of the rotating frame far away from the hollow column.

[0010] Further description: It also includes a fixed shaft, which is fixedly connected to the side of the column away from the hollow column. An angled plate is rotatably connected to the fixed shaft, and a short torsion spring is fixedly connected between the fixed shaft and the angled plate.

[0011] Further description: Multiple square holes are opened on the angled plate. When the angled plate is unfolded, it can be fixed to the ground by inserting a reinforcement rod.

[0012] The beneficial effects of the present utility model are as follows: During the construction of existing municipal engineering projects, including road construction, urban greening, water supply systems, drainage and sewage treatment, etc., after maintaining these projects of different sizes, the staff need to enclose the repaired area and surround it with warning devices. However, the installation of these warning devices is relatively complex. When enclosing, multiple warning devices need to be used in combination, or a fixed structure needs to be carried and used in combination with the warning devices. Therefore, we need a warning device that is convenient to use and easy to store. In this device, the columns are connected to each other by soft ropes and are manually pulled open by the user to form a warning area to remind passing pedestrians. In order to achieve rapid deployment and contraction, a large torsion spring is connected between the limit frame and the column. This large torsion spring realizes the retraction and release of the soft rope. Also, since there is no direct connection relationship between the four columns, the columns can be stretched in any direction to ensure complete coverage of the repaired area.

[0013] During the process of unfolding the column, the handle fixed on the column can provide a convenient unfolding method and also provide greater convenience for subsequent handling of this device.

[0014] After placing the column, the hollow column installed on the column can provide a storage space for the flashing light, ensuring that the flashing light can be stored away from light when not in use, protecting the flashing light from being knocked by foreign objects, and extending the service life of the flashing light. In order to prevent the flashing light from being rubbed by the rotating plate during the telescoping process, an arc-shaped frame is fixedly connected to the flashing light, and the rotating plate is pushed open by the arc-shaped frame. Finally, in order to ensure the sealing of the hollow column, a small torsion spring is connected to the hollow column to ensure that the rotating plate and the hollow column are always in a fitting state.

[0015] After unfolding the column, in order to further improve the warning function of this device, people first open the rotating frame, then unfold the folding plate, then turn the folding plate in any direction to improve the warning function, and finally fix the folding plate through the rotating frame. In this way, a more secure warning function is achieved. Also, due to the special state of the folding plate, it can ensure the rapid deployment and storage of the folding plate. Since this function is integrated on the column, it also reduces the complexity of use, improves the practicality of the entire device, and enhances the cost performance of the entire device.

[0016] To increase the applicable range of the entire device, the unfolding of the bevel plate and the blank area exposed by the bevel plate can provide more diverse placement methods. Also, because a short torsion spring is connected to the bevel plate, this can ensure that the bevel plate can automatically retract, further reducing the difficulty of use.

[0017] To further increase the stability of this device and avoid tipping during use, multiple square holes are opened on the bevel plate. Users can utilize these square holes for reinforcement. For example, a gas object is inserted into the bevel plate and then into the ground to achieve a stronger connection. Brief Description of the Drawings

Detailed implementation mode

[0028] The present utility model will be further described below in conjunction with specific embodiments. The illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but not to limit the present utility model.

[0029] Embodiment 1: A safety warning device for municipal engineering construction, as Figures 1-3 shown, includes a vertical column 1, the vertical column 1 is fixed on the ground, two vertically arranged rotating shafts 2 are rotatably connected to the front side and the left side of the vertical column 1 respectively, a large torsion spring 3 is fixedly connected between the rotating shaft 2 and the vertical column 1, a soft cover 4 is fixedly connected between the rotating shaft 2 and the vertical column 1, the soft cover 4 is located outside the large torsion spring 3, limit frames 5 arranged vertically are fixedly connected to the inner walls of the front side and the left side of the vertical column 1 respectively, a soft rope 6 is fixedly connected to the rotating shaft 2, and the front end of the soft rope 6 passes through the limit frame 5.

[0030] This safety warning device for municipal construction is composed of four opposing vertical columns. The technical solution is based on the right rear side. When the staff completes the maintenance work of municipal facilities, place the vertical column 1 on one side of this maintenance area, then manually pull the vertical column 1 in the corresponding direction, and then place the vertical column 1 down. When pulling the corresponding vertical column 1, the interconnected soft rope 6 is also pulled, and the limit frame 5 connected thereto also starts to rotate clockwise. At this time, the large torsion spring 3 connected to the limit frame 5 starts to tighten, and the soft cover 4 fixed on the limit frame 5 also rotates accordingly. During the pulling process of the soft rope 6, the soft rope 6 moves outward through the limit frame 5. When the staff completely finishes the maintenance work and retracts the vertical column 1, when the staff grabs the vertical column 1 on one side, the large torsion spring 3 lacking fixation starts to reset, and the interconnected soft rope 6 will also rotate counterclockwise following the limit frame 5 and start to retract. Moreover, the soft cover 4 located outside the large torsion spring 3 will also rotate counterclockwise, and finally the four vertical columns 1 shrink into a whole, waiting for the next use.

[0031] Embodiment 2: On the basis of Embodiment 1, as Figure 1 shown, a handle is fixedly connected to the right rear side of the vertical column 1. When installing, the staff pulls the handle to spread the vertical column 1 around.

[0032] When installing this device, the staff holds the handle on the vertical column 1, which can more quickly unfold the vertical column 1 and is also convenient for the staff to more conveniently carry this safety warning device.

[0033] As Figure 4 and Figure 5 shown, it also includes a hollow column 7. The hollow column 7 is fixedly connected to the upper end of the upright column 1. Rotating plates 8 are rotatably connected to the left and right sides of the upper part of the hollow column 7. A small torsion spring 801 is fixedly connected between the rotating plate 8 and the hollow column 7. An air cylinder 9 is fixedly connected to the upper end of the upright column 1. The output shaft of the air cylinder 9 is fixedly connected with a flashing light 10, and an arc-shaped frame 11 is fixedly connected to the flashing light 10.

[0034] After the staff places it in the corresponding area, start the air cylinder 9 installed at the top of the upright column 1. The air cylinder 9 drives the flashing light 10 to move upward. When the flashing light 10 moves upward, the arc-shaped frame 11 connected to the flashing light 10 also moves upward together. When the arc-shaped frame 11 moves upward a certain distance, the arc-shaped frame 11 contacts the lower end of the rotating plate 8 and pushes the rotating plate 8 upward. Because one side of the rotating plate 8 is rotatably connected to the left and right sides of the hollow column 7, the rotating plate 8 will start to rotate clockwise around the fixed point. At this time, the small torsion spring 801 connected to the rotating plate 8 also starts to tighten. The lower end of the rotating plate 8 always remains in contact with the arc-shaped frame 11. When the work is completely finished, the air cylinder 9 starts to contract, and the flashing light 10 also starts to move downward to reset. When the flashing light 10 is reset, the rotating plate 8 also rotates counterclockwise and resets under the rotation of the small torsion spring 801.

[0035] As Figure 6 and Figure 7 shown, it also includes an upright column 1. A fixed plate 12 is fixedly connected to the right side of the upright column 1. A rotating frame 13 is rotatably connected to the right side of the fixed plate 12. A fixed rod 1401 is fixedly connected to the right side of the fixed plate 12. A folding plate 14 is rotatably connected to the fixed rod 1401. The left end of the rotating frame 13 is slidably connected with a plug rod frame 15.

[0036] When the upright column 1 is unfolded to form a safety warning area, first pull out the plug rod frame 15, then rotate and open the rotating frame 13, pull out the folding plate 14 from the fixed plate 12, and then pull the folding plate 14 in the unfolding direction to make the folding plate 14 become a flat warning board. Also, because the folding plate 14 is rotatably connected to the fixed rod 1401, the staff can turn the folding plate 14 in any direction. After the work is completed, the staff first retracts the folding plate 14 to its original form, then installs the folding plate 14 back on the fixed plate 12, then rotates the rotating frame 13 back so that it contacts the fixed plate 12, inserts the plug rod frame 15 back into the rotating frame 13, and then locks the rotating frame 13.

[0037] As Figure 7 and Figure 8As shown, it further includes a fixed shaft 16, which is fixedly connected to the rear side and the lower right part of the column 1. A bevel plate 17 is rotatably connected to the fixed shaft 16, and a short torsion spring 18 is fixedly connected between the fixed shaft 16 and the bevel plate 17.

[0038] After the staff unfolds the column 1, the bevel plate 17 can be rotated around the fixed shaft 16 and made to contact the ground. At this time, the short torsion spring 18 connected to the bevel plate 17 is twisted. Finally, a heavy object is pressed on the bevel plate 17. After the work is completed, the heavy object is first removed from the bevel plate 17, and then the bevel plate 17 rotates back under the reset of the short torsion spring 18 and contacts the column 1.

[0039] As Figure 8 and Figure 9 shown, a plurality of square holes are formed in the bevel plate 17. After the bevel plate 17 is unfolded, it can be fixed to the ground by inserting a reinforcing rod.

[0040] After the bevel plate 17 is rotated and unfolded, in order to improve the fixing function of the bevel plate 17, the staff can also insert a reinforcing rod through the square hole of the bevel plate 17 to improve the reinforcement ability of the bevel plate 17. After the work is completely finished, after the staff pulls out the reinforcing rod, the warning device can be put away.

[0041] Although the present disclosure has been shown and described with reference to specific exemplary embodiments thereof, those skilled in the art should understand that various changes in form and detail may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above embodiments, but should be determined not only by the appended claims but also by the equivalents of the appended claims.
