[0037] Working principle and usage process of the utility model: When in use, first wind the two ends of the fixing belt around the surfaces of two winding rods 6 respectively, and make the fixing belt pass over the tops of two guiding rollers 9 so that the surfaces of the guiding rollers 9 are in contact with the bottom of the fixing belt. When it is necessary to carry building materials, first start the first motor 5 through the control panel 22 so that the output end of the first motor 5 drives the winding rod 6 on the top of the first mounting plate 3 to rotate, extending the fixing belt between the two winding rods 6. Then start the electric telescopic rod 112 through the control panel 22 so that the output end of the electric telescopic rod 112 drives the linkage plate 113, the sliding sleeve 103, the movable rod 8 and the guiding roller 9 to move upward. At this time, the guiding roller 9 can drive the fixing belt on its top to move upward and flatten the fixing belt. At this time, the middle section of the fixing belt is away from the carrier 1, and the user can place the building materials on the top of the carrier 1. Then turn over the limiting plate 13 to block the opening at the front side of the top of the carrier 1, so as to prevent the building materials from sliding out from the front side of the top of the carrier 1. Then start the electric telescopic rod 112 according to the highest point of the building materials to drive the guiding roller 9 to move downward. When the guiding roller 9 is lower than the highest point of the building materials, turn off the electric telescopic rod 112. Then start the first motor 5 through the control panel 22 to drive the winding rod 6 to rotate and wind the fixing belt. When the fixing belt is fully stretched, the building materials between the two guiding rollers 9 can be tightened. When the length of the building materials is short or the highest point is not inside the two guiding rollers 9, first start the second motor 19 through the control panel 22 so that the output end of the second motor 19 drives the lead screw 21 to rotate. The rotation of the lead screw 21 can drive the connecting frame 17 to move back and forth. The back-and-forth movement of the connecting frame 17 can drive the winding rod 6 and the guiding roller 9 to move back and forth, so that the two guiding rollers 9 can be moved to the outside of the building materials, with high applicability.

[0038] In summary: For this handling device for building materials, by setting the movable rod 8 and the guiding roller 9, the movable rod 8 can perform movable limiting on the guiding roller 9, and the guiding roller 9 can play a guiding role in the fixing belt between the two winding rods 6. By moving the guiding roller 9 upward, the fixing belt can be driven to move upward, facilitating the user to pick up, place and fix the building materials, solving the problem that when pulling the fixing belt, the user needs to keep pulling the pull rod to temporarily release the positioning of the winding rod, and it is inconvenient for the user to pull the fixing belt when pulling the pull rod, so multiple people are required to cooperate, and the same repetition is required during unloading, which is more troublesome to use. And when the transported material is a container filled with liquid building materials, the fixing belt is prone to adhesion with the liquid material when it sags, affecting the use.
