DETAILED DESCRIPTION

[0012] In order to more clearly understand the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0013] like Figures 1-3A cutting tool for laying EPS foam blocks based on civil engineering is shown, including a workbench 1. The EPS foam block is stably placed on the workbench 1. A plurality of vertical support columns 2 are evenly and fixedly arranged on the outer edge of the lower end of the workbench 1 to support the workbench 1. On both sides of the upper end of the workbench 1, screw rods 3 are horizontally and symmetrically arranged. One end of the screw rod 3 is connected to the transmission shaft of the motor 4. A first support block 5 is fixedly arranged between the motor 4 and the workbench 1. The other end of the screw rod 3 passes through the center of the nut 6 to limit the position of the screw rod 3. The screw rod 3 rotates under the action of the motor 4. A second support block 7 is fixedly arranged between the nut 6 and the workbench 1. By supporting the motor 4 through the first support block 5 and supporting the nut 6 through the second support block 7, the stability of the positions of the motor 4 and the nut 6 is ensured, and at the same time, the height of the screw rod 3 is increased, facilitating the passing of the output end of the first hydraulic rod mechanism 14. On the side of the screw rod 3 close to the outer edge of the workbench 1, a limiting rod 8 is horizontally arranged to limit the position of the first baffle 10. The limiting rod 8 is a cylindrical rod, facilitating the smooth movement of the first baffle 10 along the limiting rod 8. The limiting rod 8 is parallel to the screw rod 3 and has the same height. Vertical support rods 9 are fixedly arranged at both ends of the limiting rod 8 to ensure the stability of the position of the limiting rod 8. Above the workbench 1 and perpendicular to the screw rod 3 and the limiting rod 8, a first baffle 10 is vertically arranged to block the end of the EPS foam block. In the middle position on the side of the first baffle 10 close to the screw rod 3, a threaded hole 11 and a through hole 12 are opened. The threaded hole 11 corresponds to the position of the screw rod 3 and has a matching thread. The screw rod 3 passes through the threaded hole 11. The through hole 12 corresponds to the position of the limiting rod 8 and has the same diameter as the diameter of the limiting rod 8. The limiting rod 8 passes through the through hole 12. When the motor 4 is started, the screw rod 3 rotates, and the first baffle 10 moves along the screw rod 3 and the limiting rod 8 accordingly. On the workbench 1, close to the screw rod 3, a second baffle 13 is vertically arranged to block both ends of the EPS foam block. The second baffle 13 is parallel to the screw rod 3 to ensure close and reliable contact with both ends of the EPS foam block. On the upper end of the workbench 1 and on the outer edge of the limiting rod 8, a first hydraulic rod mechanism 14 is horizontally and fixedly arranged. The output end of the first hydraulic rod mechanism 14 is located below the limiting rod 8 and the screw rod 3 and is fixedly connected to the middle position on one side of the second baffle 13. The second baffle 13 moves under the action of the first hydraulic rod mechanism 14. The second baffle 13 is located below the first baffle 10 to ensure that the movements of the first baffle 10 and the second baffle 13 do not affect each other. The lower end of the first baffle 10 abuts against the upper end of the second baffle 13, and the second baffle 13 supports the first baffle 10 to further ensure the stability of the position of the first baffle 10.

[0014] A through slot 15 is provided in the middle of the upper end of the workbench 1 to facilitate the passage of the bracket 18 and the metal wire 20. A top plate 16 is horizontally arranged just above the through slot 15, and a bottom plate 17 is horizontally arranged just below the through slot 15. A bracket 18 is vertically fixedly arranged on one side of the lower end of the top plate 16. The width of the bracket 18 and the bottom plate 17 is greater than the width of the through slot 15 to ensure reliable connection between the bracket 18 and the bottom plate 17 and the workbench 1. A connecting block 19 is vertically fixedly arranged in the middle of the lower end of the bracket 18. The connecting block 19 passes through the through slot 15 and is fixedly connected to the bottom plate 17, which not only reliably connects the top plate 16 and the bottom plate 17 together, but also enables the top plate 16 and the bottom plate 17 to move along the through slot 15 with the connecting block 19. The connecting block 19 is rectangular, and the height of the connecting block 19 is the same as the thickness of the through slot 15, ensuring that the lower end of the bracket 18 and the upper end of the bottom plate 17 are in reliable contact with the workbench 1, and the width of the connecting block 19 is the same as the width of the through slot 15, ensuring that the connecting block 19 moves smoothly along the through slot 15 without position displacement. A metal wire 20 is vertically arranged between the top plate 16 and the bottom plate 17 on the side away from the bracket 18, and the metal wire 20 passes through the through slot 15. One end of the wire on the top plate 16 and the bottom plate 17 is connected to the metal wire 20, and the other end is connected to a power source. When the power is turned on, the metal wire 20 is heated, and as the metal wire 20 moves, the EPS foam block is cut. A second hydraulic rod mechanism 21 is horizontally fixedly arranged on the upper end of the workbench 1 on the side of the bracket 18 away from the metal wire 20, and the end of the second hydraulic rod mechanism 21 is fixedly connected to the bracket 18. The top plate 16, the bracket 18 and the bottom plate 17 move under the action of the second hydraulic rod mechanism 21, so that the metal wire 20 moves to cut the EPS foam block.

[0015] The distance between the first baffles 10 is greater than the width of the bracket 18 , ensuring that the first baffles 10 will not block the movement of the bracket 18 .

[0016] A base block 22 is provided at the lower end of the pillar 2, a screw rod 23 is vertically fixedly provided at the middle position of the upper end of the base block 22, a threaded slot hole 24 is vertically opened at the middle position of the lower end of the pillar 2, the screw rod 23 corresponds to the position of the slot hole 24 and the thread is matched, the screw rod 23 is arranged in the slot hole 24, and the position of the screw rod 23 in the slot hole 24 is adjusted, thereby adjusting the length of the pillar 2 to ensure the stability of the workbench 1.
