[0028] Among them, by with hydraulic cylinder 301 as the power element of lifting platform 2, makes lifting platform 2 through sliding rod 204 on lifting frame 1 to move up and down and convey building material, can avoid the fracture condition when the cooperation of toothed plate and gear, and with counterweight box 305 as the auxiliary power element of lifting platform 2, can reduce the loss needed when hydraulic cylinder 301 lifts lifting platform 2, avoids the damage of hydraulic cylinder 301 caused by long time heavy load.

[0029] Preferably, hydraulic cylinder 301 is fixedly connected with lifting frame 1, and the output end of hydraulic cylinder 301 is fixedly connected with lifting platform 2.

[0032] The counterweight box 305 is equal in weight to the lifting platform 2, when the hydraulic cylinder 301 drives the lifting platform 2 to move upward, the counterweight box 305 will move downward under the action of gravity, and at the same time, the lifting platform 2 is pulled by the lifting ropes 302, so as to reduce the influence of the gravity of the lifting platform 2 on the hydraulic cylinder 301, and the lifting platform 2 can transport heavier building materials.

[0033] Specifically, the purpose of the counterweight box 305 is to enable the lifting platform 2 to transport more building materials, and to reduce the load required to be borne by the hydraulic cylinder 301 (i.e. the load received when lifting the materials), thereby improving the service life of the hydraulic cylinder 301.

[0034] When the lifting platform 2 is lowered, the load is reduced because the materials on the lifting platform 2 have been taken away, and when the hydraulic cylinder 301 drives the lifting platform 2 to descend, only a small force is required to make the lifting platform 2 descend while the counterweight box 305 rises.

[0035] Further, when the counterweight box 305 pulls the lifting platform 2 through the lifting ropes 302, the lifting ropes 302 slide on the two groups of rollers 303, and when the lifting ropes 302 slide on the rollers 303, the rollers 303 are driven to rotate, thereby reducing the friction force generated when the lifting ropes 302 contact the lifting frame 1, and avoiding the breaking of the lifting ropes 302 when the lifting ropes 302 rub against the lifting frame 1.

[0039] Preferably, the mounting blocks 101 are fixedly connected to the four sides of the bottom side of the lifting frame 1, and threaded holes are formed in the mounting blocks 101.

[0040] When the lifting platform 2 on the lifting frame 1 conveys heavy materials and the building materials are lifted, the lifting frame 1 may be unstable. Therefore, the lifting frame 1 can be connected to the ground expansion bolts through the mounting blocks 101, so as to enhance the stability of the lifting frame 1 and avoid the unstable condition.

[0041] Preferably, the counterweight box 305 is inserted with multiple counterweight blocks 306.

[0042] The counterweight box 305 can be weighted or lightened through the counterweight blocks 306, the counterweight box 305 can be inserted with multiple counterweight blocks 306 when the lifting platform 2 conveys heavy materials, so as to reduce the energy consumption of the hydraulic cylinder 301 when lifting the lifting platform 2, and the counterweight box 305 can be lightened through the counterweight blocks 306 when the lifting platform 2 conveys light materials.

[0043] Preferably, multiple bumpers 4 are installed on the bottom side of the lifting platform 2 and below the counterweight box 305.
