[0031] Reference Figure 1 and Figure 3 As shown, the utility model provides a technical solution: an intercepting device for highway engineering construction, comprising a base plate 1 and a universal wheel 4, an extension device 2 is provided on one side of the base plate 1, and a supporting device 3 is provided on one side of the U-shaped reinforcement plate 211.

[0032] The specific configuration and functions of the extending device 2 and the supporting device 3 will be described in detail below.

[0033] Reference Figure 2As shown, in this embodiment, the extension device 2 includes a fixed plate 201, one end of which is fixedly connected to the base plate 1. Two multi-segment telescopic rods 202 are fixedly connected to one side of the fixed plate 201. The output ends of the two multi-segment telescopic rods 202 are fixedly connected to a movable plate 203. T-shaped rubber rods 204 are fixedly connected to both sides of the movable plate 203. A support plate 205 is slidably connected to the outer portion of the T-shaped rubber rods 204. The arcuate surfaces of the two multi-segment telescopic rods 202 are fixedly connected to a limit plate 210, one end of which is fixedly connected to the base plate 1. This achieves the effect of extending or contracting the multi-segment telescopic rods 202 as the movable plate 203 moves away from or toward the fixed plate 201. A U-shaped reinforcement plate 211 is fixedly connected to one side of the limit plate 210, with both ends of the U-shaped reinforcement plate 211 fixedly connected to the fixed plate 201. This prevents deformation of the limit plate 210 and the fixed plate 201. A first internally threaded ring 209 is fixedly connected to one side of the limiting plate 210. The internal threads of the first internally threaded ring 209 are connected to the screw 208. This ensures that the screw 208 and the first internally threaded ring 209 are compatible. One end of the screw 208 is fixedly connected to an I-shaped rod 207. The outer portion of the I-shaped rod 207 is slidably connected to the movable plate 203. This ensures that the rotation of the I-shaped rod 207 drives the rotation of the screw 208. One end of the I-shaped rod 207 is fixedly connected to a rotating block 206. This ensures that the rotation of the rotating block 206 drives the rotation of the I-shaped rod 207.

[0034] Reference Figure 4 As shown, in this embodiment, the support device 3 includes a servo motor 31, one end of which is fixedly connected to the U-shaped reinforcement plate 211, and the output end of the servo motor 31 is fixedly connected to a threaded rod 32. This achieves the effect of the servo motor 31 starting the output end to drive the threaded rod 32 to rotate. The arc surface of the threaded rod 32 is threadedly connected to a second internally threaded ring 33, and the arc surface of the second internally threaded ring 33 is fixedly connected to a support frame 34. The rotation of the threaded rod 32 causes the second internally threaded ring 33 to drive the support frame 34 to move. The four ends of the support frame 34 are fixedly connected to a weighted frame 35. The movement of the support frame 34 drives the movement of the weighted frame 35. Two round rods 36 are slidably connected to one side of the support frame 34, and the ends of the two round rods 36 are fixedly connected to the U-shaped reinforcement plate 211. This achieves the effect of the support frame 34 sliding on the round rods 36, and the round rods 36 prevent the support frame 34 from shifting during movement.

[0035] Working principle: Through the extension device 2, when it is necessary to intercept different road widths, the operator first pulls the fixed plate 201 and the universal wheel 4 drives the base plate 1 to move, so that the extension device 2 moves to the appropriate position, and the universal wheel 4 is locked to prevent the universal wheel 4 from rotating, and then the rotating block 206 is rotated to make the I-shaped rod 207 drive the screw 208 to rotate, so that the screw 208 is completely disengaged from the first internal thread ring 209, eliminating the limit on the movable plate 203, and moving the movable plate 203 away from the fixed plate 201, so that the output end of the multi-section telescopic rod 202 is moved by the movable plate 203 to the required position, thereby completing the interception work. Through the extension device 2, the problem of traditional interception devices used in highway engineering construction is solved, which are fixed in length. Different road surface widths are required to be intercepted, resulting in the interception distance not being able to be flexibly adjusted according to actual usage needs, resulting in limited use.

[0036] Through the support device 3, when it is necessary to enhance the stability of the intercepting device, the operator first starts the servo motor 31, and the output end of the servo motor 31 drives the threaded rod 32 to rotate, and the rotation of the threaded rod 32 drives the second internal threaded ring 33 to move, so that the second internal threaded ring 33 drives the support frame 34 to move toward the ground until the weighted frame 35 is completely in contact with the ground, thereby enhancing the stability of the intercepting device. Through the support device 3, the problem of traditional intercepting devices used in highway engineering construction being unstable and easily overturned by external forces is solved.
