[0003] For example, a material lifting device for construction disclosed in Chinese patent publication number CN213626716U includes: a base, a moving mechanism, a lifting device, a conveying mechanism and a controller; the moving mechanism is embedded in the center position of the top end of the base along the front-to-back direction; the lifting device is arranged at the top end of the moving mechanism along the up-down direction; the conveying mechanism is arranged on the right side of the lifting device along the left-to-right direction; and the controller is arranged at the left front end of the top end of the base along the up-down direction.

[0004] However, when the tower crane is in a busy state, the task of transporting construction materials to lower floors requires workers to use a lifting mechanism to transport the construction materials. However, the current lifting mechanism only has the function of lifting construction materials in the vertical direction. In this operation mode, workers are required to carry out the transportation work at the edge of the floor and remove the construction materials on the lifting platform, which makes workers face the safety hazard of falling from a height during the process of transporting construction materials.

In this operation mode, workers are required to carry out the transportation work at the edge of the floor and remove the construction consumables from the lifting platform, which makes the workers face the safety hazard of falling from a height during the process of transporting construction consumables. A movable lifting mechanism is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a movable lifting mechanism, including a mounting frame, a cross bar fixedly connected to the inside of the mounting frame, a crane is respectively provided at both ends of the cross bar, a lifting platform is suspended under the crane, a sliding telescopic arm is symmetrically fixedly installed on one side of the lifting platform, a loading platform is transmission-connected to one side of the sliding telescopic arm, material railings are respectively fixedly connected to both sides of the loading platform, a plurality of rope fixing rings are fixedly connected to one side of the material railing, and a number of rollers are respectively fixedly installed on the four corners of the mounting frame.

[0007] Preferably, the sliding telescopic arm includes a mounting chamber, an electric push rod and a mounting rod, one end of the mounting rod is slidably engaged inside the mounting chamber, the electric push rod is fixedly mounted on one side of the mounting chamber, and the driving end of the electric push rod is fixedly connected to one side of the other end of the mounting rod.

[0009] Preferably, both sides of the lifting platform are fixedly connected with a lifting rod.

[0010] Preferably, the hook of the crane is clamped on the outer side of the boom, and positioning rings are symmetrically fixedly installed on the outer side of the boom, and the positioning rings are arranged on both sides of the hook of the crane.

[0011] Preferably, a plurality of guide columns are symmetrically fixedly connected inside the mounting frame.

[0012] Preferably, a plurality of guide columns are movably connected to both sides of the lifting platform.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0024] The following is a detailed description of the specific settings and functions of this embodiment. The worker places the goods to be transported on the loading platform 4 and secures them with ropes, and then wraps the two ends of the rope around the outside of the rope fixing ring 411. Then the crane 2 lifts the lifting platform 21. After the lifting platform 21 drives the loading platform 4 and the goods to the specified height, the electric push rod 32 in the sliding telescopic arm 3 pushes the other end of the mounting rod 33 to move forward, and the mounting rod 33 slides out from the inside of the mounting bin 31. The mounting rod 33 drives the loading platform 4 to extend into the interior of the floor, so that workers can carry the goods on the loading platform 4 inside the floor without having to carry the goods at the edge of the floor, thereby avoiding the situation where workers fall or goods slip, and improving the transportation safety of the lifting mechanism; in the process of the loading platform 4 sliding forward, the second roller 421 at the other end of the loading platform 4 slides above the mounting bin 31, reducing the friction resistance of the loading platform 4 and providing support for one end of the loading platform 4.
