[0021] like Figures 1 to 4As shown, the guardrail cutting device for old road demolition includes a translation drive mechanism 1. A cutting host 2 is mounted on the top of the translation drive mechanism 1, which drives the cutting host 2 to move along it. A drive wheel 3 is mounted on one side of the cutting host 2, and a height adjustment mechanism 6 is mounted on one end of the translation drive mechanism 2. A lower guide wheel 4 corresponding to the drive wheel 3 is mounted on the bottom side of one side of the height adjustment mechanism 6, and an upper guide wheel 5 corresponding to the lower guide wheel 4 is mounted above it. The height adjustment mechanism 6 is used to adjust the height of the upper guide wheel 5. A wire saw 8 is mounted on the drive wheel 3, the upper guide wheel 5, and the lower guide wheel 4. In this embodiment, a through hole is opened on the bridge deck near the bottom of the guardrail. One end of the wire saw 8 passes through the through hole, passes from the outside of the guardrail 10, through the upper guide wheel 5 and the drive wheel 3, and connects to the other end of the wire saw 8 to form a loop. The motor in the cutting host 2 drives the drive wheel 3 to rotate, and the drive wheel 3 drives the... The wire saw 8 rotates cyclically to cut the guardrail 10. As the cutting progresses, the translation drive mechanism 1 drives the cutting host 2 to move away from the guardrail 10, tightening the wire saw 8 and cutting the guardrail 10. After multiple cuts, the guardrail 10 is divided into small sections not exceeding 2m, which are then hoisted and transported to a designated spoil disposal site. The guardrail cutting device for old road demolition in this embodiment can automatically complete the cutting of the guardrail 10, replacing manual labor, reducing labor costs, and improving cutting efficiency. The height of the concrete crash barrier is typically 70-100cm, with a maximum height generally not exceeding 110cm. The height of the upper guide wheel 5 can be adjusted by the height adjustment mechanism 6, making the height of the upper guide wheel 5 slightly higher than the top of the guardrail, thus making it suitable for cutting concrete crash barriers of different heights. In addition, the part connecting the guardrail 10 to the ground can also be cut using this device.

[0022] In some embodiments, as a specific implementation of the height adjustment mechanism 6, such as Figure 4 As shown, the height adjustment mechanism 6 has a base frame 61 fixedly mounted at the end of the translation drive mechanism 1. A lower guide wheel 4 is rotatably mounted on the side of the base frame 61 facing away from the translation drive mechanism 1. A crossbeam 63 is fixedly mounted above the base frame 61. A lifting rod 62 is slidably mounted between the crossbeam 63 and the base frame 61 in the vertical direction. An upper guide wheel 5 is rotatably mounted at one end of the lifting rod 62. A screw 65 is rotatably mounted between the crossbeam 63 and the base frame 61. The screw 65 is perpendicular to the top of the base frame 61 and is threadedly connected to the lifting rod 62. A handle 66 is provided at the top of the screw 65. By rotating the screw 65 through the handle 66, the threaded structure between the screw 65 and the lifting rod 62 can drive the lifting rod 62 to move up and down, thereby realizing the height adjustment of the upper guide wheel 5.

[0023] In some embodiments, two guide rods 64 parallel to the screw 65 are symmetrically arranged between the crossbeam 63 and the base frame 61, and the lifting rod 62 is slidably connected to the guide rods 64.

[0024] In some embodiments, a water pipe fixing mechanism 9 is provided on one end of the crossbeam 63 near the upper guide wheel 5, and a cooling water tank 7 is provided on the top of the base frame 61. A water pump is provided on the cooling water tank 7 and connected to its bottom through a pipe. A cooling water pipe is fixed in the water pipe fixing mechanism 9. One end of the cooling water pipe near the water pipe fixing mechanism 9 faces the position where the wire saw 8 contacts the top of the guardrail 10, and the other end of the cooling water pipe is connected to the outlet of the water pump. During the cutting process, the water pump sends water from the cooling water tank 7 to the position where the wire saw 8 contacts the top of the guardrail 10 to cool down the cut between the wire saw 8 and the guardrail 10.

[0025] In some embodiments, such as Figure 1 and 2 As shown, the water pipe fixing mechanism 9 has a support column 91 fixedly mounted at one end of the crossbeam 63. A mounting base 92 is rotatably mounted at one end of the support column 91. A locking bolt 93, threadedly connected to the end of the support column 91, is provided on one side of the mounting base 92. The locking bolt 93 locks or releases the mounting base 92 from the support column 91. An insertion hole 94 is provided on the mounting base 92, and a pipe clamp 95 is provided inside the insertion hole 94. A clamping bolt 96, threadedly connected to the mounting base 92, is rotatably mounted on one side of the pipe clamp 95. Tightening the clamping bolt 96 allows... Drive the pipe clamp 95 to move up and down, clamping and fixing the cooling water pipe inside the insertion hole 94. Before fixing, the length of the extension of the cooling water pipe can be adjusted along the axial direction of the cooling water pipe. After adjustment, clamp and fix it. Rotate the mounting base 92 around the support column 91 to adjust the angle of the cooling water pipe fixed inside it, so that the water outlet of the cooling water pipe is facing the position where the wire saw 8 contacts the top of the guardrail 10. After the angle is adjusted, tighten the locking bolt 93. The locking bolt 93 will press and fix the mounting base 92 against the end of the support column 91.

[0026] In some embodiments, the translation drive mechanism 1 has two parallel supports 11, with a lead screw 13 and two parallel slide rods 12 arranged between the two supports 11. The lead screw 13 is rotatably connected to the supports 11, and a drive motor 14 for driving the lead screw 13 to rotate is provided on the supports 11. The bottom of the cutting host 2 is slidably connected to the slide rods 12, and the bottom of the cutting host 2 is threadedly connected to the lead screw 13. The drive motor 14 drives the lead screw 13 to rotate, and the threaded structure between the lead screw 13 and the bottom of the cutting host 2 drives the cutting host 2 to slide along the slide rods 12, thereby realizing the movement of the cutting host 2 and the drive wheel 3. Through holes are opened at the bottom of both ends of the supports 11, so that the supports 11 can be fixed to the ground by expansion bolts during cutting.
