Technical Field

[0001] The utility model relates to the technical field of building material hoisting, in particular to a material hoisting machine for building construction. Background Technique

[0002] Building construction refers to the production activities in the implementation stage of project construction, which is the construction process of various buildings. It can also be said to be the process of turning the various lines on the design drawings into physical objects at the designated location. It includes foundation engineering construction, main structure construction, roofing engineering construction, and decorative engineering construction, etc. The place where construction operations are carried out is called a building construction site or a construction site, also called a construction site.

[0003] After retrieving Chinese Patent CN219239021U and announcing a lifting tool for precast PC components of prefabricated buildings, by setting a lifting component, during the lifting process, it can lift tubular PC precast components. There is no need to manually lift the tubular PC precast components and fix and lift them by winding steel cables. This structure is more flexible and practical, time-saving and labor-saving in the use process, improving the use effect of the device. And an adjustment component is added to this mechanism, which can adjust the distance between the limiting rod and the main body of the load-bearing beam, so as to be able to adapt to tubular PC precast components with different wall thicknesses. It can be seen that this patent requires the PC precast component to pass through the outer surface of the protective sleeve first, move the connecting seat to make the protective sleeve approach both ends of the PC precast component, and finally limit the connecting seat with a pin to lift the PC precast component well. The steps of lifting the PC precast component require at least three steps, which prolongs the hoisting time of the PC precast component. In order to facilitate the hoisting of building construction materials, a material hoisting machine for building construction is proposed. Content of the Utility Model

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figure 1-2 , a material hoisting machine for building construction, including a mounting shell 1. Support rods 2 are fixedly installed on both the front wall and the rear wall of the mounting shell 1. The shape of the support rod 2 is a quadrangular prism. A fixed shaft 3 is fixedly installed between the opposite sides of the front side wall and the rear side wall of the mounting shell 1.

[0021] Please refer to Figure 1-3 , a linkage limiting component 4 for facilitating the hoisting of building construction materials is provided on the mounting shell 1 and the fixed shaft 3. The linkage limiting component 4 includes a gear 41, a driving plate 42, a rack 43 and a lifting plate 44. The gear 41 is rotatably connected to the outer surface of the fixed shaft 3 and can rotate around the axis of the fixed shaft 3. The gear 41 is located in the mounting shell 1. The driving plate 42 is slidably connected to the front side wall of the mounting shell 1. A first slide rail 8 slidably connected to the driving plate 42 is fixedly installed on the front side wall of the mounting shell 1, and can slide up and down along the outer surface of the first slide rail 8. A second through hole 6 for the driving plate 42 to pass through is opened on the top wall of the mounting shell 1 to prevent the top wall of the mounting shell 1 from interfering with the sliding of the driving plate 42, so that the driving plate 42 can smoothly pass through the mounting shell 1. A mounting block 10 is fixedly installed on the top of the driving plate 42, and a lifting ring 11 is fixedly installed on the top of the mounting block 10, and the materials can be hoisted by connecting with the lifting ring 11.

[0022] Moreover, the rack 43 is slidably connected to the rear side wall of the mounting shell 1 and fixedly connected to the driving plate 42. A second slide rail 9 slidably connected to the rack 43 is fixedly installed on the rear side wall of the mounting shell 1. It can slide left and right along the outer surface of the second slide rail 9. The second slide rail 9 is slidably connected to the connecting frame. The first slide rail 8 and the second slide rail 9 are perpendicular to each other. A receiving hole 7 corresponding to the rack 43 is formed in the driving plate 42, which is conducive to allowing the gear 41 to pass through the receiving hole 7. The gear 41 meshes with the rack 43. When the rack 43 on the driving plate 42 moves, under the transmission of the gear 41, the two racks 43 move relatively, gradually clamping the two sides of the building construction materials, avoiding the situation that the building construction materials fall during the hoisting process. The thickness of the gear 41 is greater than the sum of the thicknesses of the rack 43 on the driving plate 42 and the rack 43 on the mounting shell 1.

[0023] Meanwhile, a first through hole 5 for the rack 43 and the connecting frame to pass through is formed in the side wall of the mounting shell 1, avoiding the side wall of the mounting shell 1 from interfering with the sliding of the rack 43 and the connecting frame. The hoisting plate 44 is fixedly installed on the side of the rack 43 away from the gear 41. Under the connection of the rack 43, during hoisting, as the driving plate 42 moves upward, under the meshing transmission of the gear 41 and the rack 43, the two hoisting plates 44 can move towards each other, facilitating hoisting according to the width of the building construction materials and avoiding the building construction materials from falling during the hoisting process. The hoisting plate 44 is slidably connected to the support rod 2, which can support and guide the hoisting plate 44, enabling the hoisting plate 44 to move along the outer surface of the support rod 2. The shape of the hoisting plate 44 is L-shaped. A connecting frame fixedly connected to the rack 43 is fixedly installed on the side of the hoisting plate 44 close to the mounting shell 1. The shape of the connecting frame is L-shaped. Diagonal rods 12 are fixedly installed on both the front wall and the rear wall of the hoisting plate 44 to limit the front wall and the rear wall of the hoisting plate 44, avoiding the building construction materials from falling during the hoisting process.

[0024] When this embodiment is in use, the building construction materials are placed on the inner bottom walls of the two hoisting plates 44, and the lifting rings 11 are tied with ropes. The electric hoist on the tower crane winds up the ropes to lift the lifting rings 11. Due to the self-weights of the mounting shell 1, the hoisting plate 44 and other structures as well as the building construction materials, the mounting shell 1 does not move upward first, and the driving plate 42 is pulled upward. Under the meshing transmission of the gear 41 and the rack 43, the two racks 43 pull the two hoisting plates 44 towards the two ends of the building construction materials, gradually clamping the building construction materials. When the side wall of the building construction materials contacts the inner side wall of the hoisting plate 44, the hoisting plate 44 stops moving. At this time, the rotation of the gear 41 is restricted, enabling the driving plate 42 to pull the building construction materials on the mounting shell 1 and the hoisting plate 44 to be hoisted, completing the hoisting work of the building construction materials.

[0025] The beneficial effects of the above embodiment are as follows:

[0026] For the material hoist for building construction, by setting the linkage limit component 4, after the linkage limit component 4 is used, the building construction materials are placed on the inner bottom walls of the two lifting plates 44 on both sides. As they are lifted, the driving plate 42 moves upward. Under the meshing drive of the gear 41 and the rack 43, the two racks 43 on both sides pull the two lifting plates 44 towards both ends of the building construction materials, gradually clamping both ends of the building construction materials. At this time, the lifting plate 44 stops moving, the gear 41 is restricted, and under the pulling of the driving plate 42, the building construction materials can be hoisted. The hoisting process only requires placing the building construction materials and then they can be hoisted, and the hoisting method is more convenient. During the hoisting process, the lifting plate 44 can move towards both ends of the building construction materials, and building construction materials of different lengths can be hoisted. Also, because there is a clamping force when the lifting plate 44 moves towards the building construction materials, it is possible to avoid the building construction materials from falling during the hoisting process. Moreover, since there are no devices such as motors, motors, electric push rods, hydraulic cylinders, and air cylinders, there is no need to use control devices to consume electric energy, achieving the purpose of energy conservation.
