BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 is a three-dimensional schematic view of the utility model structure;

[0012] Figure 2 is Figure 1 a local structure schematic enlarged view of

[0013] In the figure: crash cone barrel 1, counterweight bearing 2, outer ring 3, connecting block 4, arc-shaped clamping groove 5, U-shaped clamping block 6, protective rod 7, sleeve 8, telescopic rod 9, pit 10. DETAILED DESCRIPTION

[0014] The utility model will be described in further detail below in combination with the drawings and specific embodiments:

[0015] As Figure 1 shown, a kind of road maintenance temporary simple guardrail, including the multiple crash cone barrels 1 of being placed on the upper portion of road pit 10, crash cone barrel 1 is placed according to the width length of pit 10, when encountering smaller pit 10, can use 4 crash cone barrels 1, each crash cone barrel 1 upper portion is sleeved with counterweight bearing 2, counterweight bearing 2 uses waste old rolling bearing, its expense is lower, adjacent counterweight bearing 2 is connected with the adjustable protective rod 7, and the integrity is realized by the connection of protective rod 7 and crash cone barrel 1, improve the stability of crash cone barrel 1.

[0016] As Figure 2 shown, the outer side of counterweight bearing 2 is provided with outer ring 3, outer ring 3 is fixedly connected with the outer ring of counterweight bearing 2 by multiple connecting blocks 4, multiple arc-shaped clamping grooves 5 are formed between outer ring 3 and the outer ring of counterweight bearing 2, arc-shaped clamping groove 5 can rotate counterweight bearing 2 to realize angle adjustment, facilitate its combination connection with two side U-shaped clamping blocks 6.

[0017] As Figure 2 shown, protective rod 7 is clamped in arc-shaped clamping groove 5 by two side U-shaped clamping blocks 6 and is fixed, so that clamping dismounting is quick, convenient, time-saving and labor-saving.

[0018] As Figure 2 shown, protective rod 7 includes the sleeve 8 of center, the telescopic rod 9 of adjustable length is sleeved at the both ends of sleeve 8, and the outer end of telescopic rod 9 is connected and fixed with U-shaped clamping block 6, and the length-adjustable protective rod 7 can adapt to crash cone barrel 1 of not-through spacing, so that its connection adaptability is better, locking screw can be set on the both sides of sleeve 8 to realize the locking and fixing of telescopic rod 9.

[0019] The outer side of protective rod 7 is coated with reflective paint layer, and the reflective paint layer can play a reflective role when light is relatively dark, thereby improving the warning effect at night.

[0020] The implementation principle of the road maintenance temporary simple guardrail of the embodiment of the application is as follows:

[0021] In the initial stage of forming the pit 10, four anti-collision cone barrels 1 are placed around the upper part of the pit 10, and then the counterweight bearing 2 is sleeved on the upper part of the anti-collision cone barrel 1 to be fixed. After fixing, the U-shaped clamping block 6 at both ends of the protection rod 7 is clamped in the arc-shaped clamping groove 5 formed by the outer ring 3 and the counterweight bearing 2, so as to realize the quick connection of the protection rod 7 of the adjacent two anti-collision cone barrels 1. The telescopic arrangement of the protection rod 7 can adapt to the different spacing of the two anti-collision cone barrels 1. In this way, not only the blocking protection of the anti-collision cone barrel 1 forms a closed area, but also the counterweight bearing 2 is sleeved and placed on the top of the anti-collision cone barrel 1, which can increase the weight and is not easy to be laid flat. The stability is higher as a whole, and the safety warning effect is greatly improved.

[0022] The basic principle, main features and advantages of the present application are shown and described above. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only to illustrate the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
