[0020] like Figures 1 to 6As shown, a resource-saving device for engineering construction of the present invention comprises a conveying mechanism, which comprises an operating table 1, which can be understood as a steel panel. A plurality of sliding grooves 2 are arranged on the operating table 1, and the sliding grooves 2 are arranged perpendicular to the length direction of the operating table 1. Rotating shafts 5 are arranged inside both ends of the sliding grooves 2, and friction rollers 3 are arranged at one end of the plurality of rotating shafts 5, and the friction rollers 3 are located above the upper surface of the operating table 1. A worm gear 6 is arranged at the other end of the plurality of rotating shafts 5, and the worm gear 6 is located below the lower surface of the operating table 1. Sliding plates 4 are symmetrically arranged below the operating table 1, and the sliding plates 4 are arranged parallel to the length direction of the operating table 1. Specifically, a slide rail 10 is arranged on the lower surface of the operating table 1, and a groove is arranged on the sliding plate 4, and the groove is slidably connected to the slide rail 10. It is not difficult to understand that the sliding connection here, the sliding plate 4 It can only slide on the slide rail 10. At the same time, several rotating shafts 5 are rotatably connected to the sliding plate 4. The worm gear 6 is located below the sliding plate 4. A rotating rod 7 is provided on the sliding plate 4. Both ends of the rotating rod 7 are rotatably connected to the two ends of the sliding plate 4. A driving motor 9 is provided on one end of the rotating rod 7. The driving motor 9 is fixed to the sliding plate 4. A worm gear 6 corresponding to the number and position of the worm gear 6 is provided on the rotating rod 7. The worm gear 6 is sleeved and fixed on the rotating rod 7. Connecting ears 11 are provided on the two sliding plates 4. A driving nut 12 is provided on the connecting ears 11. A driving screw 13 is provided inside the driving nut 12. The driving nut 12 is threadedly connected to the driving screw 13. Both ends of the driving screw 13 are rotatably connected to the two side surfaces in the width direction of the operating table 1. The driving nut 12 and the setting method of the driving nut 12 can refer to the lead screw nut.

[0021] It should be noted in advance that, since the drive screw 13 and the drive nut 12 are self-locking, when the drive screw 13 rotates, it drives the drive nut 12 to move to the specified position, and the position of the sliding plate 4 is relatively fixed and will not move. At the same time, in the present embodiment, it is not difficult to understand that when the drive screw 13 rotates, the two drive nuts 12 should move towards or away from each other. As for the setting method of this movement, it is a prior art and will not be elaborated on here (such as setting two sections of threads with different rotations on the drive screw 13).

[0022] The working principle of the above technical solution is: By rotating the driving screw 13, the driving nut 12 is driven to move. The movement of the driving nut 12 will drive the sliding plate 4 to move in the width direction of the operating table 1. The movement of the sliding plate 4 will drive the rotating shaft 5, the friction roller 3 and the rotating driving motor 9 arranged thereon to move, thereby adjusting the relative positions of the friction rollers 3 symmetrically arranged on both sides of the operating table 1, that is, the spacing between the symmetrically arranged friction rollers 3 is changed, so as to adapt to the transportation of plates 28 of different widths. At the same time, the rotation of the driving motor 9 will drive the rotating rod 7 to rotate, that is, drive the worm 8 to rotate, that is, the worm 8 drives the worm wheel 6 to rotate, and then drives the friction roller 3 on the rotating shaft 5 to rotate, thereby realizing the transportation of the plate 28.

[0023] The advantage of this arrangement is that, through the arrangement of the worm gear 6 and the worm 8, one drive motor 9 can control the rotation of all the friction rollers 3 on the same side, that is, the rotation of several friction rollers 3 on the same side is unified, which improves the conveying effect while reducing the number of driving elements used in the device; at the same time, the arrangement of the sliding plate 4, the drive screw 13 and the drive nut 12 allows the position adjustment of several friction rollers 3 on the same side to be carried out in a unified manner, which improves the adjustment rate while also arranging the entire structure for adjusting the position of the friction roller 3 on the lower surface of the operating table 1, which saves the installation space of the device and reduces the overall volume; furthermore, through this arrangement, plates 28 of different widths can be conveyed, which greatly improves the practicability of the device.

[0024] In one practicable manner, it also includes a cleaning mechanism arranged at the rear end of the driving mechanism, the cleaning mechanism includes two C-shaped plates 15, the C-shaped plates 15 are fixed to the end of the operating table 1, and the open ends of the two C-shaped plates 15 are arranged opposite to each other, a rotating roller 16 is arranged inside the C-shaped plate 15, the two ends of the rotating roller 16 are respectively rotatably connected to the C-shaped plate 15, and a torsion spring is arranged on the rotating part of the rotating roller 16, the purpose of the torsion spring (not shown) is to automatically reset when the rotating roller 16 loses external force, and the outer surfaces of the two ends of the rotating roller 16 are mirror-imaged with guide grooves 17, the guide grooves 17 are arc-shaped grooves, and L-shaped rods 18 are arranged in the guide grooves 17, one end of the L-shaped rod 18 is located in the guide groove 17, and the other end of the L-shaped rod 18 passes through the C-shaped plate 15 is a side surface and is slidably connected to the C-shaped plate 15. Preferably, a limit plate 26 is provided on the protruding end of the L-shaped rod 18. Two steel wire ropes 23 (the diameter can be set according to actual conditions) are arranged in parallel between the two C-shaped plates 15. The two ends of the two steel wire ropes 23 are respectively fixed to the L-shaped rod 18 symmetrically arranged at the upper part and the L-shaped rod 18 symmetrically arranged at the lower part. A baffle rod is provided in the middle of the rotating roller 16, one end of the baffle rod is connected to the rotating roller 16, and the other end of the baffle rod is arranged pointing to the middle of the operating table 1. When the baffle rod is pushed by the end of the plate 28 to rotate to the limit position, the limit position here refers to that the end of the baffle rod is in contact with the side of the plate 28, and the two steel wire ropes 23 are in contact with the upper surface and the lower surface of the plate 28 respectively.

[0025] The working principle of the above technical solution is: When the plate 28 is conveyed by the friction roller 3, its end will contact the baffle rod, thereby pushing the baffle rod to rotate. The baffle rod will drive the rotating roller 16 to rotate while rotating, that is, when the rotating roller 16 rotates, it will drive the guide groove 17 set thereon to rotate. The rotation of the guide groove 17 will cause the end of the L-shaped rod 18 to move toward the middle of the rotating roller 16 in the guide groove 17. Therefore, the L-shaped rod 18 will slide on the C-shaped plate 15, thereby driving the wire rope 23 to move toward the middle of the rotating roller 16. That is, when the baffle rod rotates to contact the side of the plate 28, the plate 28 can no longer push the baffle rod, that is, the baffle rod has rotated to the extreme position at this time, that is, the wire rope 23 just moves to contact the surface of the plate 28, and then during the movement of the plate 28, the wire rope 23 will contact and cut the concrete on the plate 28, thereby cleaning the concrete on its surface.

[0026] By means of the contact between the steel wire rope 23 and the concrete, the concrete on the plate 28 is blocked and separated from the surface of the plate 28. Compared with the cleaning method in the prior art using a scraper (which will cause cutting damage to the surface of the plate 28) or a grinding wheel set by extrusion (which will cause extrusion depression on the surface of the plate 28), this method will not cause damage to the surface of the plate 28.

[0027] In one feasible manner, a fixed block 19 is provided on the rotating roller 16, one end of the fixed block 19 is fixed to the middle part of the rotating roller 16, a rotating plate 20 is provided on one end of the baffle plate, a locking bolt is provided on the rotating plate 20, and the locking bolt connects the rotating plate 20 to the fixed block 19. By loosening the locking bolt, the rotating plate 20 can be rotated, and then the inclination angle of the baffle rod can be adjusted, that is, the rotation angle when the end of the plate 28 pushes the baffle rod to rotate to the extreme position is adjusted, and then the rotation angle of the rotating roller 16 can be controlled, and then the rotation angle of the guide groove 17 can be controlled, and then the moving distance of the L-shaped rod 18 can be controlled, and then the moving distance of the wire rope 23 can be controlled, and then the spacing between the two steel wire ropes 23 can be controlled, and then the wire rope 23 can be used on plates 28 of different thicknesses, and then concrete cleaning operations can be performed on plates 28 of different thicknesses.

[0028] In one feasible manner, the baffle rod includes an inner rod 22 and an outer rod 21, the inner rod 22 and the outer rod 21 are threadedly connected, and the end of the inner rod 22 is fixedly connected to the rotating plate 20, that is, the baffle rod is configured to have an adjustable length, and the distance between the end of the baffle rod and the middle of the operating table 1 can be controlled, so that it can adapt to plates 28 of different widths, so that the ends of plates 28 of different widths can drive the baffle rod to rotate.

[0029] In one feasible manner, adjusting bolts 25 are provided on both side surfaces of the C-shaped plate 15, and the adjusting bolts 25 are threadedly connected to the C-shaped plate 15. A pressure plate 24 is provided on the end of the adjusting bolt 25 facing the wire rope 23, and the pressure plate 24 presses against the wire rope 23. By rotating the adjusting bolt 25, the pressure of the pressure plate 24 on the wire rope 23 can be controlled, and then the pressure of the wire rope 23 in contact with the surface of the plate 28 can be controlled. Then, during the operation of the device, the pressure of the wire rope 23 on the surface of the plate 28 can be adjusted according to actual conditions, and then the cleaning effect of the wire rope 23 on the surface of the plate 28 can be adjusted.

[0030] In one feasible manner, a compression spring is provided on the end of the adjusting bolt 25, one end of the compression spring is fixed on the pressure plate 24, and the other end of the compression spring is fixed on the end of the adjusting bolt 25. The setting of the compression spring can enable the steel wire rope 23 to overcome the resistance of the compression spring when it contacts the stubborn concrete (the contact surface is firm and not easy to fall off) on the plate 28, so that the compression spring is deformed, and then the steel wire rope 23 moves along the surface of the stubborn concrete in the direction away from the middle of the rotating roller 16, so as to achieve the purpose of overcoming obstacles. This setting method can avoid the steel wire rope 23 from being blocked and broken, and can also avoid the problem that the friction force of the friction roller 3 is difficult to drive the plate 28 to move due to the obstruction of the steel wire rope 23.

[0031] In one practicable manner, a rotating disk 14 is provided on one end of the driving screw rod 13 to facilitate the operator to perform rotation adjustment.

[0032] In one practicable manner, an annular groove is provided in the middle of the driving roller, and guiding slopes are provided on the outer sides of both ends of the annular groove, and the guiding slopes can limit and guide both sides of the plate 28 to improve the conveying effect. At the same time, it is not difficult to understand that support legs 27 are provided at the four corners of the operating table 1, and one end of the support leg 27 is fixed on the operating table 1.

[0033] A method for using a resource-saving device for engineering construction comprises the following steps: The driving screw 13 is rotated to adjust the relative positions of the friction rollers 3 on both sides so that the distance between the friction rollers 3 on both sides matches the width of the plate 28; Rotate the outer rod 21 to adjust the relative position of the outer rod 21 to the inner rod 22, and then adjust the length of the blocking rod so that the distance between the two symmetrically arranged blocking rods is smaller than the width of the plate 28; Adjust the locking bolts to adjust the inclination angle of the stopper rod connected to the rotating roller 16, and then adjust the moving distance of the L-shaped rod 18 in the guide groove 17 when the plate 28 pushes the stopper rod to rotate to the limit position, so that the wire rope 23 is in close contact with the two surfaces of the plate 28; The plate 28 is placed in the friction roller 3 at the end of the operating table 1 , and the friction roller 3 can drive the plate 28 to move into the cleaning mechanism to clean the concrete on the plate 28 .

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
