Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Embodiment: Refer to Figures 1-7 a kind of foundation pit safety protection device for a new type of road project shown, which includes a placing plate 1, on the top surface of the placing plate 1, a warning sign 2 is installed by bolts, which is used to remind passing pedestrians and vehicles. On the bottom surface of the placing plate 1, there are legs 4 for support. And for further reminder and protection, a protection mechanism 7 is provided on the legs 4. The protection mechanism 7 is used for two purposes: one is to improve the warning purpose, and the other is to protect the foundation pit.

[0023] In order to be adapted to the foundation pit accordingly, the legs 4 are connected to the placing plate 1 through the connector 3, and the legs 4 themselves have the function of adjusting the length. With the above-mentioned connector 3, foundation pits of various sizes and specifications can be protected.

[0024] Connector 3: The top block 31 is provided on the bottom surface of the placement plate 1, and two of them form a group. The top block 31 is hinged to the bottom block 35. Telescopic grooves 32 and limit grooves 36 are respectively provided on the mating surfaces of the top block 31 and the bottom block 35. In order to control the turning angle of the support leg 4, a limit pin 34 is slidably connected in the telescopic groove 32. The outer end of the limit pin 34 is hemispherical, and the limit groove 36 is a hemispherical groove and is adapted to the limit pin 34. Under the action of the spring 33, the limit pin 34 is pushed outwards to abut against the limit groove 36, realizing the limit of the inclination angle of the support leg 4. Multiple groups of limit grooves 36 are arranged in a circular array, facilitating multi-angle adjustment.

[0025] Support leg 4: In order to cooperate with the opening angle, the distance between the upper support leg 41 and the lower support leg 42 can be adjusted. An adjustment groove 44 is provided on the bottom surface of the upper support leg 41, and an adjustment rod 43 provided at the top of the upper support leg 41 is slidably connected in the adjustment groove 44. In order to adjust the upper support leg 41 and the lower support leg 42, an adjustment hole communicating with the inside and outside is provided at the position of the adjustment groove 44, and an adjustment bolt 45 is threadedly connected in the adjustment hole. After tightening, the adjustment rod 43 is limited to prevent it from loosening and slipping. The support foot 6 hinged to the bottom of the lower support leg 42 contacts the ground.

[0026] A protection mechanism 7 is provided in the placement groove 46 provided on the upper support leg 41 and cooperates with the hook 5 on the outer wall of the support leg 4 to meet the support legs 4 at different inclination angles.

[0027] Protection mechanism 7: A U-shaped protection member 71 (as Figure 3 shown) is installed in the placement groove 46. A winding rod 72 is rotatably connected in the space surrounded by the protection member 71 (on the placement groove 46). A protection cloth 73 is wound around the winding rod 72. In order to enable the stretched protection cloth 73 to automatically retract, a clockwork spring is provided at the connection of the winding rod 72. And in order to prevent the free end of the protection cloth 73 from retracting into the protection member 71, a placement hook 76 is provided on the outer wall of the placement groove 46, and the placement hook 76 is adapted to the pull rod 74 on the free end of the protection cloth 73. And after the above-mentioned protection cloth 73 is pulled out, the pull rod 74 is placed on the hook 5 and cooperates with the warning strip provided on the outer wall of the protection cloth 73 to play a function of reminding for protection.

[0028] In order to reduce the wear during the use of the protection cloth 73, a guide rod 75 for turning the protection cloth 73 is provided in the placement groove 46 to prevent the protection cloth 73 from directly contacting the protection member 71 and causing wear.

[0029] Working principle of this utility model: According to the size of the foundation pit on the road, the legs 4 at the bottom of the placing plate 1 are flipped. The bottom block 35 on the top surface of the upper leg 41 flips on the top block 31, and the flipping force is greater than the force of the spring 33, causing the limit pin 34 to slide out of the limit groove 36 and retract into the telescopic groove 32. After the leg 4 is flipped, under the action of the spring 33, the limit pin 34 is inserted into the telescopic groove 32 to complete the operation of the leg 4; then the adjusting bolt 45 is turned to make the adjusting rod 43 slide in the placing groove 46, pulling the lower leg 42 and the upper leg 41 in opposite directions, causing the adjusting rod 43 to slide in the adjusting groove 44. After adjusting to an appropriate length, the adjusting bolt 45 is tightened again; then the pull rod 74 is held and separated from the placing hook 76, and the pull rod 74 is pulled outwards. The pull rod 74 drives the protective cloth 73 to move outwards, thereby driving the winding rod 72 to rotate in the placing groove 46. The rotating winding rod 72 drives the clockwork to work. The protective cloth 73 passes through the guide rod 75 to avoid contacting the protective member 71. Then the pull rod 74 is placed on the hook 5 to complete the protective warning function.

[0030] The electromechanical connection involved in this utility model is a common means adopted by those skilled in the art and can obtain technical inspiration through a limited number of tests, belonging to common general knowledge.

[0031] The components not described in detail in this article are prior art.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
