[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 5As shown, the utility model provides a safety warning device for geotechnical construction, including a base 1, a cylinder 3 is fixedly connected to the inside of the base 1, a pull rod 4 is rotatably connected to the side of the cylinder 3 away from the base 1, a first connecting rod 6 is rotatably connected to the side of the pull rod 4 close to the cylinder 3, the first connecting rod 6 is rotatably connected to the second connecting rod 7 on the side away from the pull rod 4, the second connecting rod 7 is rotatably connected to the third connecting rod 8 on the side away from the first connecting rod 6, a fixed rod 10 is fixedly connected to one side of the inside of the base 1, a sliding sleeve 9 is rotatably connected to the upper surface of the fixed rod 10, and a universal wheel 11 is fixedly connected to the side of the third connecting rod 8 away from the second connecting rod 7.

[0022] The cylinder 3 pushes the pull rod 4, and the pull rod 4 starts to move, which in turn causes the pull rod 4 to drive the first connecting rod 6 to show an obvious folding phenomenon. When the first connecting rod 6 is folded, the second connecting rod 7 closely connected to it also starts to move synchronously, driving the third connecting rod 8 to move together, and the third connecting rod 8 drives the universal wheel 11 to fold on the fixed rod 10 through the clever setting of the sliding sleeve 9. In this way, the entire safety warning device can be easily pushed through the setting of the universal wheel 11, meeting the needs of flexible transfer between different construction sites. At the same time, after being pushed to the appropriate position, the universal wheel 11 can be folded and retracted. When the universal wheel 11 is folded and retracted, the entire safety warning device can contact the ground over a large area, greatly increasing the contact area, thereby making the device more stable and reliable. This design effectively solves the stability problem of the safety warning device during use, allowing the safety warning device to perform at its best whether in a mobile state or a stationary state, and ultimately achieving the ideal effect of the safety warning device being able to be placed stably.

[0023] like Figure 1 、 Figure 2 As shown, the side of the pull rod 4 away from the cylinder 3 is fixedly connected to the spring 401, the side of the spring 401 away from the pull rod 4 is fixedly connected to the auxiliary wheel 5, the side of the base 1 is fixedly connected to the warning sign 2, and the side of the base 1 away from the warning sign 2 is fixedly connected to the chassis 13.

[0024] Using the above solution, a spring 401 is fixedly connected to the side of the pull rod 4 away from the cylinder 3. When the universal wheel 11 is folded, the auxiliary wheel 5 can be folded synchronously by virtue of the elastic action of the spring 401. The provision of the auxiliary wheel 5 is of great significance. It can make the safety warning device more stable and reliable during the pushing process. The overall triangular structure of the device greatly enhances the stability of the device and effectively prevents the entire device from tipping over during use. A warning sign 2 is fixedly connected to one side of the base 1. The warning sign 2 clearly reminds pedestrians and vehicles that this is a construction site and they should avoid approaching. This warning function plays an important role in ensuring construction safety and reducing the occurrence of accidents. The side of the base 1 away from the warning sign 2 is fixedly connected to the chassis 13. The provision of the chassis 13 effectively protects the internal structure, effectively preventing damage due to external impact or other factors, thereby extending the service life of the safety warning device and ensuring its stable and reliable function in various complex construction environments.

[0025] like Figure 3 、 Figure 4 As shown, a movable disk 14 is movably connected to one side of the chassis 13, and the movable disk 14 is rotatably connected to the chassis 13 through a rotating shaft. A fixed elastic member 12 is fixedly connected to one side of the movable disk 14, and the side of the fixed elastic member 12 away from the movable disk 14 is fixedly connected to the chassis 13.

[0026] The above-mentioned solution is adopted: a movable disk 14 is movably connected to one side of the chassis 13. The setting of the movable disk 14 facilitates the folding of the universal wheel 11. When the universal wheel 11 is opened to push it, the movable disk 14 can also prevent the internal structure from being hit by stones on the ground and causing damage. A fixed elastic part 12 is fixedly connected to one side of the movable disk 14. The setting of the fixed elastic part 12 can prevent the movable disk 14 from falling and opening, resulting in the appearance that the entire safety warning device cannot be pushed.

[0027] like Figure 2 、 Figure 3 As shown, the third connecting rod 8 is composed of multiple rods, the number of the first connecting rod 6, the second connecting rod 7, the third connecting rod 8, the fixed rod 10, and the universal wheel 11 is set to two, the number of the sliding sleeves 9 is set to four, and the sliding sleeves 9 are fixedly connected to the third connecting rod 8.

[0028] The above-mentioned scheme is adopted: by setting the number of the first connecting rod 6, the second connecting rod 7, the third connecting rod 8, the fixed rod 10, and the universal wheel 11 to two, the overall device can run more stably when pushed, and it is also convenient for the pushing action of the universal wheel 11. The sliding sleeve 9 is fixedly connected to the third connecting rod 8, so that the third connecting rod 8 can run under the push of the cylinder 3 and other structures while driving the sliding sleeve 9 to run on the fixed rod 10, so that the overall universal wheel 11 device can be folded after the overall safety warning device is pushed to facilitate the stable stopping effect.

[0029] The working principle and use process of this utility model:

[0030] When it is necessary to move the safety warning device, the cylinder 3 is started, and the cylinder 3 pushes the pull rod 4 to move. When the pull rod 4 moves, it drives the first connecting rod 6 to rotate, and the first connecting rod 6 then pushes the second connecting rod 7 to move, and the second connecting rod 7 pushes the third connecting rod 8. Since one side of the third connecting rod 8 is fixedly connected to the universal wheel 11, under the transmission action of this series of connecting rods, the universal wheel 11 is pushed out of the base 1, so that the safety warning device can be moved conveniently. At the same time, the sliding sleeve 9 fixedly connected to the third connecting rod 8 slides on the fixed rod 10 to play a stabilizing and guiding role. When the safety warning device needs to be moved, When the device is fixed in a certain position, the cylinder 3 contracts and the pull rod 4 is pulled back. Similarly, through the transmission action of the connecting rod, the universal wheel 11 is retracted into the base 1. At this time, the safety warning device can be stably placed on the ground to play a warning role. In addition, the spring 401 and the auxiliary wheel 5 are fixedly connected on the side of the pull rod 4 away from the cylinder 3. During the movement of the safety warning device, the auxiliary wheel 5 can play an auxiliary support and stabilization role. The chassis 13 on the side of the base 1 away from the warning sign 2 can protect the internal structure and prevent the internal structure from being damaged by external force impact or other factors.
