Warning signs are generally used for early warning during maintenance operations.

[0003] However, most existing safety warning devices used in highway maintenance operations have limited height. In actual use, it has been found that their relatively low height makes it difficult for distant vehicles to see them in time. They can only be seen when the vehicle is close by, which can easily lead to a situation where the reaction is not timely and safety accidents occur.

[0004] Furthermore, the existing safety warning devices have a fixed height, which cannot be adjusted according to the actual environment (such as poor visibility) during use. This results in the devices being used too high or too low, requiring manual assistance such as raising them, which is inconvenient and affects the warning effect. Utility Model Content

A vertically lifting highway maintenance early warning device, configured as follows: Figure 1 and 2 As shown, the device includes a base 1, a pair of limiting columns 2 located at both ends of the rear side of the base 1, a turbine lift 3 located in the middle of the limiting columns 2 and fixed to the base 1, a liftable mounting frame, and a detachable warning screen 9 mounted on the mounting frame. The lower middle part of the mounting frame is connected to the turbine lift 3, and the two sides are connected to lifting columns 4 that are lifted and fitted inside the limiting columns 2. The turbine lift 3 includes a body, a column 31, and a lifting rod 32 that is lifted and fitted inside the column 31. The body drives the lifting rod 32 to rise and fall. The base 1 is equipped with a power distribution box 8 connected to the warning screen 9 via a circuit. The power distribution box 8 adopts a common structure and is used to supply power to the warning screen 9.

[0023] The turbine lift 3 can be any commonly available one on the market. Depending on the actual needs, an electric turbine lift or a hand-cranked turbine lift can be selected. The lifting rod 32 can also be a screw lifting structure or a rack and pinion lifting structure, depending on the actual needs.

[0024] Furthermore, the base 1 is equipped with a detachable counterweight to ensure that the entire unit can be placed stably without tipping over during use. The bottom of the base 1 is equipped with multiple rollers and fixed feet corresponding to the lower ends of the four legs. The rollers facilitate the movement and handling of this application, and the fixed feet adopt a commonly available adjustable screw structure to lower the fixed feet for support and fixation during use.

[0025] The mounting frame includes a pair of side mounting plates 5 respectively located inside the corresponding lifting column 4 and a lower support plate 53 located on the top of the lifting rod 32; each side mounting plate 5 is provided with a lower baffle 51 for supporting the warning screen 9 below and an upper baffle 52 that can be rotated and opened and closed above.

[0026] The mounting bracket uses a common snap-fit ​​structure to support and install the warning screen 9; the warning screen 9 can be any commonly available on the market, and has warning text display function and sound and light warning function.

[0027] like Figure 3 As shown, the base 1 is provided with a pair of inclined support plates 61; each support plate 61 corresponds one-to-one with the limiting column 2; the top of the support plate 61 is connected to the upper end of the limiting column 2, and the bottom is connected to the front side of the base 1, forming a triangle with the limiting column 2, the support plate 61 and the base 1; the top of the support plate 61 is connected to the limiting column 2 through a reinforcing block 64; the support plate 61 can be fixed by welding, riveting or other methods, and the triangular structure provides support, improving the overall structural strength.

[0028] The upper part of the support plate 61 is connected to a horizontally arranged reinforcing rod 62; each support plate 61 has an upper outer side provided with a mounting sleeve 63 for installing the reinforcing rod 62, and the two ends of the reinforcing rod 62 are connected to detachable limiting screw blocks; the mounting sleeve 63 has a horizontal through hole; the limiting screw block is connected to the reinforcing rod 62 through a threaded structure, and the limiting screw block is located outside the mounting sleeve 63.

[0029] Furthermore, welding or other methods can be used to directly fix the reinforcing tie rod 62 horizontally to the support plate 61 to improve the structural strength.

[0030] like Figure 4 As shown, the lifting column 4 is slidably lifted and sleeved inside the limiting column 2; the limiting column 2 has a sliding groove 21, and the upper end of the limiting column 2 has a pair of horizontally arranged and left-right distributed limiting wedges 23, a transverse groove 22 for the limiting wedges 23 to move laterally, and a compression spring for driving the limiting wedges 23 to move laterally; the bottom of the lifting column 4 has a sliding protrusion 42 that slides against the inner wall of the sliding groove 21, and the sliding protrusion 42 has a limiting groove 43 corresponding to the limiting wedges 23.

[0031] The limiting wedge 23 and the lifting column 4 form a wedge mechanism. When the lifting column 4 descends, it drives the limiting wedge 23 to move outward laterally. When the lifting column 4 rises, when it rises to the limiting groove 43, the limiting wedge 23 moves inward laterally under the action of the compression spring and enters the limiting groove 43 for locking.

[0032] The lifting column 4 has vertically arranged limiting slots 41 on its front and rear sides, and the inner wall of the limiting column 2 has a limiting guide bar corresponding to the limiting slots 41; the setting of the limiting guide bar and the limiting slots 41 makes the lifting more stable.

[0033] Working principle:

[0034] The application is placed on a highway maintenance vehicle or on the highway. The staff adjusts the limit feet to limit the movement and installs counterweights as needed to ensure overall stability and prevent tipping. Then, the turbine lift 3 is operated manually or electrically to drive the lifting rod 32 to rise, which in turn lifts the mounting frame and the warning screen 9 installed on the mounting frame. The power is turned on, and the warning screen 9 begins to provide text, sound and light warnings to remind vehicles behind to pay attention to safety.
