[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 A material feeding device for construction engineering includes a base 1, a channel steel column 2 fixedly connected to the top surface of the base 1, a plurality of crossbars 3 fixedly connected to the outer surface of the channel steel column 2, a sliding seat 4 slidably connected to the inner wall of the channel steel column 2, an anti-fall component 5 fixedly connected to one side of the sliding seat 4, a slide rail 6 fixedly installed on the front of the sliding seat 4, a shelf 7 fixedly connected to the top of the slide rail 6, a top plate 8 fixedly connected to the top of the channel steel column 2, a pulley 9 bolted to the top surface of the top plate 8, a winding reel 10 and a reduction motor 11 fixedly connected to the top surface of the base 1, and a steel wire rope 12 wound around the outer surface of the winding reel 10.

[0025] The anti-fall component 5 includes a side block 51 fixedly connected to one side of the sliding seat 4. A stop bar 52 is rotatably connected to the outer surface of the side block 51. An anti-fall rod 53 is fixedly connected to the outer surface of the stop bar 52. A counterweight ball 54 is fixedly connected to the outer surface of the anti-fall rod 53 near the bottom. A limit block 55 is fixedly connected to the outer surface of the side block 51. A tension spring 56 is connected between the limit block 55 and the stop bar 52.

[0026] Specifically, a fence 13 is fixedly connected to the top surface of the shelf 7, and a barrier 14 is hinged to one side of the shelf 7. A hanging ring 15 is fixedly connected to the top of the fence 13. One end of the wire rope 12 is wrapped around the outer surface of the hanging ring 15. A rotating shaft is fixedly connected to the center of the end face of the winding reel 10. The output shaft of the reduction motor 11 is connected to the rotating shaft of the winding reel 10 through a coupling. The advantage is that by placing building materials on top of the storage board 7 and surrounding the storage board 7 with a fence 13 and a barrier 14, the materials can be prevented from slipping off the storage board 7 during the loading process. Furthermore, a bolt is installed between the barrier 14 and the fence 13, allowing the barrier 14 to be opened and closed for easy unloading. When the reduction motor 11 is started, it drives the winding reel 10 to rotate. The winding reel 10 can wind up the wire rope 12, which pulls the lifting ring 15, which in turn pulls the fence 13. The fence 13 then pulls the storage board 7 to raise it, thus transporting the materials from the ground to a higher position and realizing the loading process.

[0027] Specifically, the bottom surface of the shelf 7 is bolted to a slide rail 6, and the front of the sliding seat 4 is fixedly connected to two sets of slide rails 6. The sliding seat 4 consists of a C-shaped plate 41 and guide wheels 42. Eight guide wheels 42 are rotatably connected to the inner side of the C-shaped plate 41. The advantage is that by setting the guide wheels 42 to fit against the inner side of the channel steel column 2, the entire sliding seat 4 slides along the direction of the channel steel column 2 during the rising or falling of the shelf 7. The eight guide wheels 42 reduce frictional resistance, making the lifting operation very smooth. Because of the slide rails 6, when the enclosure 14 is pulled, the shelf 7 can be moved, and the shelf 7 will cause the slide rails 6 at its bottom to extend, thus extending the position of the shelf 7. Since the entire device is placed against the wall during use, the shelf 7 can extend a distance after reaching the specified height, which allows for safer unloading.

[0028] Specifically, multiple horizontal bars 3 are fixedly connected at equal intervals on the outer surface of the channel steel column 2. The stop bar 52 and the anti-fall bar 53 form a 90-degree angle. Pins are fixedly connected to the outer surfaces of both the limiting block 55 and the stop bar 52, and a tension spring 56 connects two pins. The advantage is that, by observing the attached diagram in the instruction manual... Figure 3It is known that during the upward movement of the sliding seat 4, the entire anti-fall assembly 5 will be driven to rise. Since the stop lever 52 and the anti-fall lever 53 are fixedly connected, and the stop lever 52 is rotatably connected to the side block 51 via a shaft, the stop lever 52 will be forced to rotate clockwise after it moves upward and touches the crossbar 3. At this time, it will also drive the anti-fall lever 53 to rotate clockwise. Therefore, during the upward movement of the shelf 7, the anti-fall lever 53 cannot contact the crossbar 3. When the loading is completed, the shelf 7 needs to be lowered. At this time, the sliding seat 4 drives the entire anti-fall assembly 5 to descend, and the stop lever 52 will still touch the crossbar 3, thus forcing the stop lever 52 to rotate counterclockwise. In this way, the anti-fall lever 53 also rotates counterclockwise. When the stop lever 52 passes a crossbar 3, it will be under the action of the counterweight ball 54. Immediately, the anti-fall bar 53 is reset to a vertical position, which in turn resets the stop bar 52 to a horizontal position. At this time, the anti-fall bar 53 will not directly contact the crossbar 3. It is worth noting that the weight of the counterweight ball 54 is greater than the tension of the tension spring 56. Since the reduction motor 11 drives the shelf 7 to rise and fall at a constant speed, the sudden breakage of the wire rope 12 will accelerate the rapid fall of the shelf 7 and the materials on it. At this time, the weight of the counterweight ball 54 itself is not enough to reset the anti-fall bar 53, so the anti-fall bar 53 will contact one of the crossbars 3, and then continue to drive the stop bar 52 to rotate counterclockwise and contact the limit block 55. At this time, the anti-fall bar 53 will be stuck, thereby achieving the purpose of fixing the shelf 7 and achieving the effect of preventing fall.

[0029] In use, first place the building materials on top of the shelf 7, and use the fence 13 and the barrier 14 to surround the shelf 7. Close the barrier 14 with the bolt to prevent the materials from slipping. Then start the reduction motor 11, which drives the winding reel 10 to rotate. The winding reel 10 winds up the wire rope 12, which pulls the lifting ring 15. The lifting ring 15 pulls the fence 13, which in turn pulls the shelf 7 upward. During the upward movement, the guide wheel 42 of the sliding seat 4 slides along the inner side of the channel steel column 2, and the anti-fall component 5 rises accordingly. After the stop bar 52 touches the crossbar 3, it will rotate clockwise and drive the anti-fall bar 53 to rotate. The shelf 7 reaches the designated position. After reaching the desired height, pull the barrier 14 to extend the slide rail 6 at the bottom of the storage plate 7, extending the position of the storage plate 7 for safe unloading. After loading is complete, the reduction motor 11 reverses to lower the storage plate 7. At this time, the stop bar 52 touches the crossbar 3 and rotates counterclockwise, driving the anti-fall bar 53 to rotate. After the stop bar 52 passes the crossbar 3, the anti-fall bar 53 and the stop bar 52 are reset under the action of the counterweight ball 54. If the wire rope 12 suddenly breaks, the storage plate 7 and the material fall rapidly. The counterweight ball 54 cannot reset the anti-fall bar 53 in time. The anti-fall bar 53 contacts the crossbar 3 and drives the stop bar 52 to rotate counterclockwise until it contacts the limit block 55 and is locked, thereby fixing the storage plate 7 to prevent it from falling.
