[0028] Reference Figure 1-4 The utility model provides a high-efficiency steel cutting device for bridge engineering construction: it includes a workbench 1, the bottom of the workbench 1 is fixedly connected with four brackets 2, one side of each of the two brackets 2 is provided with a slide groove 3, a fixing plate 4 is fixedly connected to the inside of one of the slide grooves 3, a threaded rod 5 is rotatably connected between the bottom of the fixing plate 4 and the inner wall of the slide groove 3, a fixing rod 6 is fixedly connected to the inside of the other slide groove 3, a threaded block 7 is threadedly connected to the outer surface of the threaded rod 5, a slider 8 is sleeved on the outer surface of the fixing rod 6, both sides of the threaded block 7 and the slider 8 are respectively slidably connected to the two sides of the inner walls of the two slide grooves 3, one side of the threaded block 7 and one side of the slider 8 are fixedly connected with a connecting block 9, a supporting plate 10 is fixedly connected between the two connecting blocks 9, a sliding assembly is provided on the supporting plate 10, a motor 11 is provided on the top of the fixing plate 4, and the output end of the motor 11 is fixedly connected to one end of the threaded rod 5.

[0029] The sliding assembly includes a slot 12 opened on the top of the support plate 10, and a sliding plate 13 is movably connected inside the slot 12. Four installation slots 14 are opened at the bottom of the sliding plate 13, and connecting rods 15 are fixedly connected between the opposite sides of the inner walls of the four installation slots 14. A pulley 16 is rotatably sleeved on the outer surface of the connecting rod 15. The thickness of the sliding plate 13 is higher than the depth of the slot 12. A push handle 17 is fixedly connected to the top of the sliding plate 13. An inclined slot 18 is opened on the top of the workbench 1, and the sliding plate 13 is movably connected inside the inclined slot 18. Through the setting of the sliding assembly, it is convenient for the staff to move the bridge steel placed on the top of the sliding plate 13 to the workbench 1.

[0030] Two square grooves 19 are provided on the top of the workbench 1. The sizes of the two square grooves 19 match the sizes of the two connecting blocks 9, and the two connecting blocks 9 are movably connected inside the two square grooves 19 respectively. An electric telescopic rod 20 is fixedly connected to the top of the workbench 1. The telescopic end of the electric telescopic rod 20 is fixedly connected to a device block 21. A cutting machine 22 is provided on one side of the device block 21. When the position of the steel to be cut is moved to the bottom of the cutting machine 22, the cutting machine 22 is started and the electric telescopic rod 20 is electrically extended. The contraction of the electric telescopic rod 20 drives the running cutting machine 22 to move downward to cut the steel.

[0031] Working principle: When the bridge steel needs to be transported to the workbench 1 for processing, the bridge steel can be moved to the side of the device using a cart, and the bridge steel is manually placed on the sliding plate 13 on the support plate 10, and then the motor 11 is started to drive the threaded rod 5 to rotate, thereby driving the threaded block 7 and one of the connecting blocks 9 to move up, and driving the support plate 10 and the other connecting block 9 to move up, so that the slider 8 moves on the fixed rod 6. When the top of the support plate 10 is flush with the top of the workbench 1, the motor 11 is turned off and the sliding plate 13 is pushed by the handle, and the sliding plate 13 slides inside the slot 12 under the cooperation of the four pulleys 16. The sliding plate 13 moves and continues to push the sliding plate 13 into the inclined slot 18 on the top of the workbench 1. When the sliding plate 13 moves to the inclined slot 18, the horizontal plane of the sliding plate 13 moves downward, and the bridge steel remains on the top of the workbench 1, and the sliding plate 13 slides into the inclined slot 18. When the bridge steel is completely moved to the top of the workbench 1, the sliding plate 13 is taken out from the inclined slot 18. Under the weight of the bridge steel itself, the sliding plate 13 will not bring the bridge steel out, so the sliding plate 13 is moved back to the inside of the slot 12, and the motor 11 is started again to drive the support plate 10 to move downward, and prepare for the next bridge steel transportation work.
