Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and more specifically, it relates to a hoist for building engineering. Background Technology

[0002] During the construction process, various equipment are needed to work together to complete the building structure, including hoists. Hoists transport materials to higher places, facilitating construction. With scientific advancements, hoists have become increasingly smaller and more flexible, meeting the diverse needs of construction. They can conveniently lift materials required for construction, such as sand, gravel, cement, and slabs.

[0003] However, when existing hoists lift building materials such as sand, gravel, and soil, they generally have the problem of not being able to quickly and fully discharge the building materials from the storage bin after the material reaches the designated position. In addition, some hoists require manual unloading, which is inconvenient to use.

[0004] Furthermore, the storage bins installed at the external end of most existing elevators are connected by various transmission mechanisms and cannot be disassembled. This means that when lifting materials from distant locations, external equipment is still needed for transportation, which is quite troublesome. Utility Model Content

[0031] Please see Figures 1-5 A hoist for construction engineering includes a storage box 1 with an open front end and a baffle 2 hinged to the bottom of the opening. A push plate 3 is slidably mounted inside the storage box 1. A moving block 4 is fixedly mounted on the upper surface of the push plate 3 at the middle position. Vertical plates 5 are fixedly mounted on the upper surface of the storage box 1 at both the front and rear sides. A lead screw 6 is rotatably mounted at the middle position of the vertical plate 5 and is threadedly mounted to the moving block 4. A first motor 7 is mounted on one end of the lead screw 6 on the outer wall of the vertical plate 5. Wheels 8 are rotatably mounted on the bottom of the storage box 1 at each of the four corners. A base 9 is mounted on the lower end of the wheel 8. A protective shell 10 is mounted on the upper surface of the base 9. The front end of the protective shell 10 is open and the front end of the base 9 has an inclined surface. Slider blocks 25 are fixedly mounted on both sides of the push plate 3. A corresponding groove 26 is opened on the inner wall of the storage box 1, and the slider 25 is slidably mounted to the groove 26.

[0032] In this embodiment, a mounting frame is provided on the upper end face of the protective shell 10. A rope winding roller 11 is rotatably provided inside the mounting frame. Ropes 12 are provided on both sides of the rope winding roller 11. A second motor 13 is provided at one end of the rope winding roller 11 and on the outer wall of the mounting frame. The lower ends of the ropes 12 pass through the protective shell 10 and are provided with connecting cylinders 14. Connecting posts 15 are fixedly provided on the upper end face of the storage box 1 and on both sides. The connecting posts 15 can enter the interior of the connecting cylinders 14. The connecting posts 15 and the connecting cylinders 14 are respectively provided with through holes 16. Connecting pins 17 are movably provided inside the through holes 16. Nuts 18 are provided at the outer end of the connecting cylinders 14. The nuts 18 are threadedly connected to the connecting cylinders 14. Both ends of the connecting pins 17 are in contact with the inner wall of the nuts 18.

[0033] More specifically, when the material reaches the designated position, the user can control the first motor 7 to rotate the lead screw 6. At this time, the lead screw 6 will drive the moving block 4 and the push plate 3 to move, so as to push out the sand or soil inside the storage box 1, achieving the effect of rapid material discharge. When it is necessary to lift the material at a more distant position, the nut 18 can be rotated first to disengage it from the connecting pin 17. At this time, the connecting pin 17 can be removed, and then the connecting column 15 and the connecting cylinder 14 can be separated to facilitate the removal of the storage box 1 from the protective shell 10 for conveying the material at a more distant position. After that, the storage box 1 containing the material is pushed back into the protective shell 10, and the connecting column 15 is put into the connecting cylinder 14. Then, the connecting pin 17 is installed into the insertion hole 16, and the nut 18 is rotated to block the connecting pin 17 and prevent it from coming off. At this time, the second motor 13 can be controlled to rotate the rope roller 11 to drive the storage box 1 to rise, achieving the effect of lifting the material.

[0034] Please see Figure 2 , Figure 4 and Figure 5 As an implementation method for shielding the front end of the storage box 1: both sides of the storage box 1 are provided with fixing blocks 19, and the middle position of the fixing blocks 19 is provided with positioning pins 20. Both sides of the baffle 2 are provided with positioning holes 21. One end of the positioning pin 20 is located inside the positioning hole 21, and the other end of the positioning pin 20 is fixedly provided with a pull block 22. A tension spring 23 is fixedly provided between the pull block 22 and the fixing block 19.

[0035] Specifically, the user can pull the lever 22 to disengage one end of the positioning pin 20 from the positioning hole 21, at which point the baffle 2 can be rotated to facilitate the quick removal of materials from the storage box 1, thereby increasing efficiency.

[0036] Please refer to Figure 1As a further embodiment for limiting the rope 12, a guard plate 24 is provided on both sides of the rope 12 and on the outer wall of the winding roller 11.

[0037] Specifically, the rope 12 can be limited to prevent it from moving and affecting the stability of the storage box 1.

[0038] In summary, when using the overall equipment: when it is necessary to lift materials from a distant location, the nut 18 can be rotated first to disengage it from the connecting pin 17. The connecting pin 17 can then be removed, allowing the connecting column 15 and connecting cylinder 14 to be separated. This facilitates the removal of the storage bin 1 from the protective housing 10 for conveying materials from a distant location. Afterwards, the storage bin 1 containing the material is pushed back into the protective housing 10, and the connecting column 15 is inserted into the connecting cylinder 14. The connecting pin 17 is then installed into the insertion hole 16, and the nut 18 is rotated to cover the connecting pin 17, preventing it from coming loose. At this point, the second motor 13 can be controlled to rotate the rope roller 11, thereby lifting the storage box 1 and achieving the effect of lifting the material. When the material reaches the designated position, the pull block 22 can be pulled to disengage one end of the positioning pin 20 from the positioning hole 21. At this time, the baffle 2 can be rotated to open the front end of the storage box 1. Then, the first motor 7 can be controlled to rotate the lead screw 6. The lead screw 6 will then drive the moving block 4 and the push plate 3 to move, thereby pushing out the sand or soil inside the storage box 1, achieving the effect of rapid material discharge and increasing the material lifting efficiency.
