[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Please refer to Figures 1 to 5, the present utility model provides a technical solution: a handling device for construction engineering materials, including a first placement rack 1. A limiting groove 2 is provided inside the first placement rack 1. A limiting plate 3 is slidably connected inside the limiting groove 2. One end of the limiting plate 3 is connected to a second placement rack 4, which is a telescopic structure, enabling the second placement rack 4 to pull out the limiting plate 3 from the limiting groove 2 by a corresponding length, facilitating the adjustment of the overall length of the device and reducing the space occupation when not in use. The structure of the limiting plate 3 is T-shaped, which helps prevent the limiting plate 3 from disengaging from the limiting groove 2. A plurality of positioning holes 12 are provided inside the limiting plate 3. A fixing rack 13 is installed on one side of the first placement rack 1 and at the bottom of the limiting plate 3. A threaded column 14 is threadedly connected inside the fixing rack 13. One end of the threaded column 14 is connected to a bolt 15. One end of the bolt 15 is inserted into one of the positioning holes 12, so that when the threaded column 14 rotates, it moves up and down, driving the bolt 15 to be inserted into the positioning hole 12 to fix the limiting plate 3, or to be pulled out therefrom to release the fixation of the limiting plate 3. Positioning racks 5 are installed on one side of both the first placement rack 1 and the second placement rack 4. Grooves 6 are provided inside both the first placement rack 1 and the second placement rack 4 and above the limiting groove 2. Inlets and outlets 22 are provided at the top of the grooves 6 inside both the first placement rack 1 and the second placement rack 4. A wire winding disc 7 is rotatably connected inside the groove 6. A traction rope 8 is wound around the outer side of the shaft of the wire winding disc 7. One end of the traction rope 8 passes through the inlet and outlet 22 and is connected to a lobster buckle 9 that cooperates with the positioning rack 5. By locking the lobster buckle 9 with the positioning rack 5, the traction rope 8 bypasses the construction materials on the first placement rack 1 and the second placement rack 4 and binds them, while not hindering the placement of materials with larger volumes. A worm gear 10 and a worm 11 are rotatably connected inside the groove 6 and on one side of the wire winding disc 7. The worm gear 10 and the worm 11 are meshed with each other. Rotating handles 16 are rotatably connected to the sides of both the first placement rack 1 and the second placement rack 4 away from the positioning rack 5. The worm gear 10 and the worm 11 are respectively fixed to the wire winding disc 7 and the rotating handle 16. Under the meshing action of the worm gear 10 and the worm 11, the rotating handle 16 and the wire winding disc 7 are driven, facilitating the control of the rotation of the wire winding disc 7 to wind up the traction rope 8, and facilitating the adjustment of the length of the traction rope 8 according to materials of different volumes, so as to tie up the materials and prevent them from falling. Anti-slip layers 21 are provided on the surfaces of both the first placement rack 1 and the second placement rack 4, which helps increase the friction with the surface of the materials, making it not easy for them to slide and disengage from the first placement rack 1 and the second placement rack 4. A positioning sleeve 17 is installed on the top of the first placement rack 1. A handrail 18 is rotatably connected inside the positioning sleeve 17. A locking bolt 19 is threadedly connected to one side of the positioning sleeve 17. One end of the locking bolt 19 extends into the positioning sleeve 17. The structure of the handrail 18 is L-shaped, enabling the handrail 18 to adjust the angle with the first placement rack 1 by rotation and being fixed under the action of the locking bolt 19. An anti-slip sleeve 20 is sleeved on the outer side of the handrail 18, increasing the friction with the hand, making it not easy for the hand to disengage from the handrail 18 and facilitating the holding of the handrail 18.

[0023] In summary, when the building engineering material handling device is in use, through the sliding connection between the limiting groove 2 in the first placing rack 1 and the limiting plate 3 at one end of the second placing rack 4, the second placing rack 4 is pulled to make the limiting plate 3 extend a corresponding length. After adjusting the overall length of the device, the threaded column 14 connected by internal threading in the fixed rack 13 on one side of the first placing rack 1 is rotated, so that one end of it is displaced, driving the bolt 15 to insert into the positioning hole 12 at the corresponding position in the limiting plate 3. The building materials are placed on the first placing rack 1 and the second placing rack 4. At this time, the lobster buckle 9 drives the traction rope 8 to bypass the building materials, and after connecting the lobster buckle 9 to the positioning rack 5 on one side of the first placing rack 1, the turning handle 16 on the other side of the first placing rack 1 is rotated, driving the worm 11 in the groove 6 in the first placing rack 1 to rotate. Under the action of the meshing of the worm gear 10 and the worm 11 and the connection between the worm gear 10 and the winding disc 7, the winding disc 7 rotates accordingly, winding the traction rope 8 to tighten and bind the materials. Similarly, by repeating the operation, the traction rope 8 on the second placing rack 4 can be used to fix the materials secondly. Since the handrail 18 is rotatably connected inside the positioning sleeve 17 on the first placing rack 1, therefore, by rotating the handrail 18, the angle between the handrail 18 and the first placing rack 1 can be adjusted according to requirements, and the locking bolt 19 connected by threading on one side of the positioning sleeve 17 is rotated, so that one end of it is displaced and presses and fixes the handrail 18. Holding the handrail 18, the first placing rack 1 and the second placing rack 4 can be pushed to displace to carry the materials.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
