By operating the lifting mechanism 9, the wire rope assembly 16 can be wound or unwound, thus lifting and lowering the support plate 2.

[0026] like Figure 2As shown, this utility model provides a technical solution for an efficient and convenient building material handling and lifting device: The front end of the bearing plate 2 has a vertically penetrating connecting groove 201; the middle of each of the two supports 13 has a horizontally penetrating insertion hole 130; the front ends of the inner walls of the opposite sides of the U-shaped guardrail 4 have directional grooves 401; a protrusion 41 is fixedly connected to the top of the U-shaped guardrail 4 near the directional groove 401; T-shaped sliders 42 are fixedly connected to the middle sides of the back of both the U-shaped guardrail 4 and the bearing plate 2; the outer walls of the two T-shaped sliders 42 are slidably connected to the inner wall of the T-shaped slide groove 101; during the lifting process, the bearing plate 2 and the U-shaped guardrail 4 slide along the T-shaped slide groove 101 via the T-shaped sliders 42, thus providing support for the bearing plate. The movement trajectory of the 2 is limited. The fence mechanism 5 includes a base frame 51, several guardrail plates 52, a top frame 53 and two locking components 54.

[0027] like Figure 3 As shown, this utility model provides a technical solution for an efficient and convenient building material handling and lifting device: the locking component 54 includes an insert block 541, a fixed plate 542, a snap-on plate 543, and two lever blocks 544. The front end of the insert block 541 is fixedly connected to the bottom of the rear end of the fixed plate 542. The top of the fixed plate 542 is provided with a movable groove 5420. The bottom of the left and right ends of the snap-on plate 543 is rotatably connected to the inner wall of the movable groove 5420. The upper side of the snap-on plate 543 is provided with a slot 54 that matches the protrusion 41 and is vertically connected. 30. One end of each of the two levers 544 is fixedly connected to the upper side of the left and right ends of the buckle plate 543, and one end of the insert block 541 is fixedly connected to the front side of the outer wall of the top frame 53. The outer wall of the insert block 541 is inserted into the inside of the directional groove 401, and the inside of the slot 5430 is engaged with the outside of the protrusion 41. After the second guard strip 52 is placed vertically on the bearing plate 2, so that the insert block 541 is inserted into the directional groove 401, the buckle plate 543 is then flipped over so that the slot 5430 is engaged with the outside of the protrusion 41.

[0028] like Figure 4As shown, this utility model provides a technical solution for an efficient and convenient building material handling and lifting device: the wire rope assembly 16 includes a wire rope 161, a connecting block 162, a pin 163, and a nut 164. The end of the wire rope 161 is fixedly connected to the top of the connecting block 162. The pin 163 is L-shaped, and the top of the pin 163 in the vertical direction is fixedly connected to the bottom of the connecting block 162. The outer wall of the horizontal surface of the pin 163 is provided with a threaded groove 1630. The outer wall of the horizontal surface of the pin 163 passes through the interior of the insertion hole 130 and is threadedly connected to the inner wall of the nut 164. One end of the threaded groove 1630 in the pin 163 passes through the insertion hole 130 along the outer wall of the bracket 13 and is screwed onto the pin 163 by the nut 164, thereby installing the wire rope 161 on the bracket 13 for easy disassembly.

[0029] like Figure 5 As shown, this utility model provides a technical solution for an efficient and convenient building material handling and lifting device: a handle 81 is fixedly connected to the rear end of the mounting plate 8; the lifting mechanism 9 includes two support frames 91, a stepper motor 92, two turntables 93, a rotating roller 94, and an annular partition 95; the bottoms of the two support frames 91 are fixedly connected to the left and right sides of the top of the mounting plate 8; the left and right ends of the rotating roller 94 are fixedly connected to the middle of the opposite sides of the two turntables 93; the center end of the outer wall of the left turntable 93 is rotatably connected to the inner wall of the left support frame 91; the output shaft of the stepper motor 92 passes through the inner wall of the support frame 91 and is connected to the right turntable 93. The center end is fixedly connected, and the output shaft of the stepper motor 92 drives the rotating roller 94 to rotate through the turntable 93, so that the steel wire ropes 161 on both sides are wound up synchronously. The steel wire ropes 161 on both sides lift the bearing plate 2. The inner wall of the annular partition 95 is fixedly connected to the middle side of the outer wall of the rotating roller 94. The tails of the two steel wire ropes 161 are respectively wound around the left and right sides of the outer wall of the rotating roller 94 near the annular partition 95. The outer wall of the steel wire rope 161 is wound and connected to the outer wall surface of the fixed pulley 15. During the pulling process of the steel wire rope 161, the steel wire rope 161 slides along the surface of the fixed pulley 15 to achieve the effect of saving effort.

[0030] The working principle of this efficient and convenient building material handling and lifting device will be explained in detail below.

[0031] like Figure 1-5As shown, when using this device to transport and lift building materials, firstly, the battery in the battery pack 7 is connected to the stepper motor 92 via wires to provide power to the stepper motor 92. The building materials are then stacked on the support plate 2, ensuring that the top of the building materials does not exceed the height of the U-shaped guardrail 4. Then, the top frame 53 is flipped upwards, and the bottom frame 51 rotates along the connecting groove 201. The inserts 541 on both sides are inserted into the directional grooves 401 respectively. Then, the buckle plate 543 is rotated backwards along the movable groove 5420, so that the buckle 5430 is engaged along the outside of the protrusion 41, locking the top frame 53. This makes the second guardrail 52 perpendicular to the support plate 2, working with the first guardrail 3 to protect the building materials on the support plate 2. The worker holds the handle 81 with both hands and... The device is pushed and moved to the lifting position by the caster wheel 12. Then the stepper motor 92 is started. The output shaft of the stepper motor 92 drives the roller 94 to rotate through the turntable 93, which drives the wire rope 161 on the roller 94 to wind up. The outer wall of the wire rope 161 lifts the bearing plate 2 upward along the fixed pulley 15. During the lifting process, the T-shaped slider 42 slides along the T-shaped groove 101 to further limit the movement trajectory of the bearing plate 2, so that the bearing plate 2 is lifted vertically upward along the positioning plate 10. After the wire rope 161 has been used for a long time, the surface will show severe wear. The nuts 164 on both sides can be rotated off the pins 163, and then the pins 163 can be removed from the insertion holes 130 to disassemble and replace the wire rope 161.

[0032] The specific types and structures of the battery pack and stepper motor used are existing products, as are the specific circuit connection structure and control relationship between the battery pack and the stepper motor. These will not be elaborated upon here.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
