DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1 As shown, a construction material hoist includes a receiving plate 2, a lifting device 1 is fixedly connected to the upper end of the receiving plate 2, a support frame 3 is fixedly connected to the lower end of the receiving plate 2, a fixed component 4 is slidably connected to the left and right ends of the support frame 3, a containing component 5 is slidably connected inside the two fixed components 4, and a widening plate 6 is fixedly connected to the lower end of the support frame 3.

[0027] During the specific implementation of this solution, the device is first placed between two floors where materials need to be lifted, and the widened plate 6 is fixed by bolts or welding so that the two containing components 5 are aligned with the floors on the same side. The materials are then placed inside the containing components 5 and fixed, and the lifting device 1 is started to lift the containing components 5 on both sides. After reaching the lifted floor, the containing components 5 are started and moved to the upper part of the floor slab to facilitate workers to unload materials.

[0028] Specifically, in order to reduce the risk of workers falling from buildings while unloading materials, refer to Figure 2 and Figure 3 The fixing assembly 4 includes a fixing bar 41, and the four corners of the lower end of the fixing bar 41 are fixedly connected to sliding rods 45, and the outer surfaces of the four sliding rods 45 are slidably connected to the sleeves 44. The outer surfaces of the four sliding rods 45 and the four sleeves 44 are jointly sleeved with springs 42, and the lower ends of the four sleeves 44 are jointly fixedly connected to the bottom plate 43, and the upper and lower ends of the four springs 42 are respectively fixedly connected to the fixing bar 41 and the bottom plate 43;

[0029] For further information, see Figure 2 , both fixed bars 41 are slidably connected to the support frame 3;

[0030] For further information, see Figure 2 The containing assembly 5 includes a containing frame 51 slidably connected to the fixed bar 41, a front side of one end of the containing frame 51 away from the supporting frame 3 is rotatably connected to a frame door 52, and a driving assembly 53 is fixedly connected to the front of the lower end of the containing frame 51;

[0031] For further information, see Figure 3 The driving assembly 53 includes a rack 531, a gear 532 is meshedly connected to the lower part of the outer surface of the rack 531 away from the support frame 3, and a motor 533 is fixedly connected to the middle part of the front end of the gear 532;

[0032] For further information, see Figure 3 , the two motors 1 533 are fixedly connected to the fixed bar 41 on the same side through the connecting seat, the two racks 531 are connected to the racks 531 on the same side, and the two motors 1 533 pass through the fixed bar 41 through the coupling at the output end and extend to the front end of the gear 1 532 on the same side and are rotatably connected to the fixed bar 41;

[0033] It can be seen that when the material loading is completed, the lifting device 1 is started to lift the fixing components 4 on both sides, and the sleeves 44 on both sides slide upward on the outer surface of the support frame 3 until they reach the floor where the material is needed, and then the motors 533 on both sides are started to drive the gear 532 on the same side to start rotating, so that the two racks 531 can be driven to move away from each other, and the containing frame 51 on the same side can be driven to be placed on the upper part of the floor slab of the floor. At this time, the worker can open the frame door 52 and unload the material inside the containing frame 51 inside the floor. After the completion, the motors 533 on both sides are started again to drive the containing frame 51 to reset;

[0034] Subsequently, the lifting device 1 is started again to drive the fixed components 4 on both sides to move downward until they reach the ground to facilitate loading. When the bottom plate 43 contacts the ground, as the fixed bar 41 continues to descend, the slide bar 45 will begin to be squeezed to make it slide inside the casing 44, and the spring 42 will also be squeezed. That is, the slide bar 45 is used to slide inside the casing 44 to ensure the stability of the spring 42 when it is compressed, and the fixed bar 41 continues to be buffered to avoid direct contact with the ground and excessive impact force causing damage to the device.

[0035] Specifically, in order to improve the efficiency of material lifting and the practicality of the device, refer to Figure 4 and Figure 5 The lifting device 1 includes a motor 2 11 and four rope drums 12. The motor 2 11 penetrates the rope drum 12 on the same side through a coupling at the output end and is fixedly connected to the axis of the rope drum 12 on the same side. The axis of the front rope drum 12 and the axis of the rear rope drum 12 are both fixedly connected to two mutually meshing gears 2 15. The two gears 2 15 located on the right are both fixedly connected to the axis of the rope drum 12 located in the middle on the same side. Ropes 13 are wound inside the four rope drums 12. Rollers 14 are provided on the outer surfaces of the four ropes 13. The four rollers 14 are rotatably connected to the receiving plate 2.

[0036] For further information, see Figure 4 , the four rope drums 12 are all rotatably connected to the receiving plate 2, the motor 2 11 is fixedly connected to the receiving plate 2 through the connecting seat, the tails of the two ropes 13 on the outside face the left, and the tails of the two ropes 13 on the inside face the right, and the four ropes 13 are all fixedly connected to the fixed fence 41 on the same side;

[0037] The rope drum 12 is composed of a drum and a roller. The ropes 13 on the same side are all wound around the rollers on the same side. The front and rear are connected to the axis of the rollers. When the motor 11 is started, the four rollers are driven to rotate, and the ropes 13 on the outer surface of the rollers are retracted and released in turn.

[0038] It can be seen that when the motor 2 11 is started, the roller inside the rope drum 12 on the same side can be driven to rotate, and the rope 13 on the front side begins to shrink. Under the action of the two gears 2 15, the two inner ropes 13 are retracted and released in opposite directions, so that the two inner ropes 13 begin to shrink to the right, and the two outer ropes 13 begin to shrink to the left, and the lifting of the left and right fixed components 4 is completed synchronously. During the process of shrinking or lowering the rope 13, the roller 14 on the same side will rotate accordingly, reducing the friction of the rope 13 rising or lowering, thereby indirectly improving the transportation efficiency of the fixed components 4 on both sides.

[0039] It should be noted that the specific installation method, circuit connection method and control method of the two motors 1 533 and the motor 2 11 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
