DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-3 The illustrated construction site dangerous area monitoring and alarm device comprises a monitoring alarm 1 and a support 2 arranged on the monitoring alarm 1. The support 2 is provided with a connecting plate 3 and a bottom plate 4 from top to bottom. During the operation of the monitoring alarm 1, the bottom plate 4 contacts the ground. The support 2 is used to support the monitoring alarm 1 and maintain the installation height of the monitoring alarm 1. When the monitoring alarm 1 is in operation, it can monitor the dangerous area in the construction site and has an alarm function to prevent pedestrians from mistakenly entering the dangerous area of ​​the construction site.

[0023] Since the ground at the construction site is mostly muddy and has a certain degree of ruggedness, in order to improve the stability of the connecting plate 3 and the bottom plate 4 and ensure the stable operation of the monitoring alarm 1, a plurality of limit pins 5 that can be raised and lowered are evenly distributed on the connecting plate 3 and the bottom plate 4. The plurality of limit pins 5 are distributed in a triangular point, and the bottom ends of the plurality of limit pins 5 are provided with an embedded rod 51 with a conical structure. The embedded rod 51 can be embedded in the ground as the limit pin 5 descends, thereby improving the stability of the connection between the bottom plate 4 and the ground, and effectively preventing the bottom plate 4, the connecting plate 3 and the pillar 2 from shaking and deflecting on the muddy ground. The bottom plate 4 and the entire device are suitable for different installation environments. A pressure structure is provided on the limit pin 5, which can suppress the limit pin 5 so that it is not easy to deflect upward and leave the soil.

[0024] like Figure 4 , Figure 5As shown, a guide channel 52 is provided on the surface of the limit pin 5. In a natural state, the guide channel 52 is exposed above the connecting plate 3, and a limit roller 53 which can move synchronously with the limit pin 5 is provided on the inner side of the limit pin 5.

[0025] The connecting plate 3 is provided with a plurality of extension frames 6 facing the guide channel 52, and the tops of the plurality of extension frames 6 are provided with alignment ears 61, and the opposite sides of each extension frame 6 are fixed by a middle plate 62. When the limit pin 5 moves, the guide channel 52 and the limit roller 53 move synchronously, and the relative positions of the two and the extension frame 6 change.

[0026] like Figure 4 , Figure 5 As shown, the pressure structure includes two stop blocks 7 arranged on the moving path of the limit pin 5, and the two stop blocks 7 are provided with connecting rods 71, and the two connecting rods 71 ​​are connected by a rotating shaft, and the rotating shaft is arranged on the alignment ear 61. When the limit pin 5 drops to the limit level, the stop block 7 is located above the limit roller 53 and abuts against its surface. The stop block 7 has an intercepting effect on the limit roller 53, so as to achieve the purpose of intercepting the movement of the limit pin 5.

[0027] like Figure 4 , Figure 5 As shown, during the construction process, with the continuous operation of large machinery, there is a vibration force on the ground. In order to prevent the vibration force in the soil from affecting the tightness of the connection between the limit pin 5 and the soil, the middle plate 62 is set at the center position of the angle space formed by the two stop blocks 7, and the two stop blocks 7 are connected to the middle plate 62 through the pressure spring 8. When the limit pin 5 descends, the limit roller 53 squeezes the stop block 7 to deviate around the rotating shaft until the pressure spring 8 shrinks. When the limit pin 5 descends to the limit level, the stop block 7 is located above the limit roller 53. Under the elastic potential energy of the pressure spring 8, the stop block 7 can quickly return to its position and abut against the surface of the limit roller 53.

[0028] The pressing of the limit roller 53 by the stop block 7 can effectively prevent the limit roller 53 and the limit pin 5 from shaking or moving upward under the vibration force of the external environment, thereby improving the tightness of the contact between the limit pin 5 and the soil after being embedded in the ground, and further improving the stability of the limit pin 5.

[0029] like Figure 3 As shown, multiple sets of guide rods 9 are provided in the relative space between the connecting plate 3 and the bottom plate 4, and the limit pin 5 is provided with a guide protrusion 54, which is sleeved on the guide rod 9. The connection between the guide rod 9 and the guide protrusion 54 can maintain the linearity of the limit pin 5 during the lifting and lowering movement, and prevent the limit pin 5 from rotating and deflecting. When the limit pin 5 moves up and down, the guide protrusion 54 moves along the direction of the guide rod 9.

[0030] like Figure 3As shown, in order to facilitate the staff to press the limit pin 5 down with their feet, a pressing plate 55 is provided on the limit pin 5, and the pressing plate 55 is located above the connecting plate 3.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
