Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building engineering, especially relates to a building engineering material hoist. BACKGROUND

[0002] In the field of building engineering, vertical transportation of materials is one of the key links in the construction process. With the acceleration of urbanization, various types of building projects are emerging, and the scale and height of buildings are continuously increasing, which makes the demand for material lifting equipment increasing and the requirements more and more strict. However, the traditional building engineering material hoist has many drawbacks, which seriously restricts the construction efficiency, safety and cost control.

[0003] 1. Poor stability of traditional hoist: The structure design of some traditional material hoists is not reasonable enough. During the process of lifting materials, especially when the weight distribution of materials is uneven or the lifting height is high, it is easy to shake or even tilt. This not only threatens the safe transportation of materials, but also may cause equipment damage and delay construction progress. For example, in some high-rise residential construction projects, the hoist with simple frame structure has obvious insufficient overall stability when hoisting heavy building materials such as prefabricated boards, which greatly affects the construction efficiency.

[0004] 2. Insufficient safety protection: The early material hoist has obvious defects in safety protection. There is no effective buffer device, and when the hoist descends to the ground, it cannot buffer the impact force of the loading box in time, which is easy to cause violent collision between the loading box and other parts, resulting in material scattering, equipment damage and even personnel injury.

[0005] 3. Inconvenient to move: The moving way of traditional material hoist is relatively single, and most of them need to be carried and repositioned by external large mechanical equipment such as crane, which not only increases the construction cost, but also limits the flexible use of hoist in construction site. In some projects with narrow space or complex construction environment, this inconvenience is particularly prominent. For example, in the urban old community renovation project, due to the limited space, the traditional hoist is difficult to move quickly to different construction building positions, which affects the overall progress of construction.

[0006] 4. Poor wear resistance of loading box: There are various types of materials carried in building engineering, among which there are some materials with sharp corners or high hardness, such as bricks, stones and steel bars. The inner wall of traditional loading box is usually not specially treated, and in the process of frequent loading and unloading of these materials, the inner wall is easy to be worn, which shortens the service life of the loading box and increases the equipment maintenance cost. In addition, the wear of the loading box may also cause material leakage, resulting in chaos and material waste in the construction site.

[0007] In summary, therefore, there is an urgent need for a technology to make up for the above shortcomings. Utility model content

[0015] (2) safety protection enhancement: the design of buffer of the utility model is a big safety highlight of the utility model. When charging box drops to reach ground or because of the big impact force of accidental situation, T type block slides in outer tube under the action of impact force, and compresses spring, and the elastic deformation of spring can absorb and buffer the impact force of charging box.

[0017] (4). The loading box durability is improved: the wear-resistant protective layer arranged on the inner wall of the loading box effectively copes with the diversity of the transported materials in the construction engineering. When the materials with sharp corners or high hardness such as bricks and stones and steel bars are frequently loaded and unloaded, the wear-resistant protective layer can bear the friction of the materials, and the abrasion of the inner wall of the loading box is greatly reduced. This not only prolongs the service life of the loading box and reduces the equipment maintenance cost, but also avoids the material leakage problem caused by the abrasion of the loading box, maintains the neatness of the construction site, and reduces the material waste.

[0018] (5). Convenient and labor-saving operation: the handle arranged on the box door facilitates the operator to open and close the box door. Compared with the complex box door opening mode of the traditional elevator, the operator can more easily and quickly perform the loading and unloading operation, saves time and physical strength, and improves the work efficiency.
