Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to hoisting machines for building construction. Background Technology

[0002] Building construction, or housing construction project, refers to the construction of buildings for residential, office, and commercial activities. It covers the entire process from design and construction to maintenance. Building construction includes foundation construction, main structure, roofing, and interior decoration, emphasizing safety, aesthetics, and usability. Building construction often requires the handling of large amounts of building materials. To improve efficiency and reduce manual labor, small hoisting machines have become important equipment on construction sites. Small hoisting machines are convenient for transporting building materials in confined spaces and are suitable for building construction projects with lower floors, effectively improving construction efficiency and ensuring construction safety.

[0003] Building hoists, especially small hoists, are important equipment for material handling in construction. They are small in size and easy to operate, making them suitable for use in confined spaces and low-rise construction sites. Small hoists are commonly used to transport building materials such as bricks, cement, and sand, significantly improving handling efficiency and reducing manpower burden. They are flexible in installation and can be quickly deployed in different locations, making them suitable for diverse building construction needs. Due to their small size and light weight, small hoists are relatively inexpensive and are widely used in residential, commercial, and small building construction projects.

[0004] In building construction, small hoists are widely used to move heavy objects such as bricks, stones, and sandbags, especially in the construction or decoration of multi-story buildings. However, due to the lack of counterweight function, most existing small hoists rely on placing some of the goods at the bottom of the hoist. During the hoisting process, these goods are prone to displacement or sliding, causing the hoist to become unstable or even tilt. This instability is particularly dangerous in high-rise construction. Therefore, a hoist for building construction is proposed to solve the above problems. Utility Model Content

[0035] Reference Figure 1 and Figure 3 The drive assembly 5 includes a double-ended motor 501, which is fixedly connected to the top of the middle side of the vertical plate 2. The double-ended motor 501 is a Y-series three-phase asynchronous horizontal motor, model Y2-80M1-4, used to provide driving force. A small bevel gear 502 is fixedly connected to the rear end of the double-ended motor 501, and the front end of the double-ended motor 501 is fixedly connected to the rear end of the cable reel 8. A small bevel gear 503 is rotatably connected to the top inside the vertical plate 2. The small bevel gear 502 and the small bevel gear 503 mesh with each other for transmission. A linkage rod 504 is fixedly connected inside the small bevel gear 503. A large bevel gear 505 is fixedly connected to the bottom of the base plate 1. A linkage rod 504 is used to synchronously rotate the large bevel gear 505. A large bevel gear 506 is rotatably connected inside the base plate 1. The large bevel gear 505 and the large bevel gear 506 mesh with each other to transmit power. The small bevel gear set and the large bevel gear set rotate at the same speed. A threaded rod 507 is fixedly connected to the middle of the large bevel gear 506.

The front end of the threaded rod 507 is rotatably connected to the inside of the base plate 1. The threaded rod 507 is used to control the movement of the counterweight frame 601.

[0036] Reference Figure 3The fixing component 7 includes a lever 701, which is slidably connected to one side of the inside of the counterweight frame 601. A connecting plate 702 is fixedly connected to the bottom of the lever 701. The lever 701 and the connecting plate 702 are connected, and the lever 701 can move the connecting plate 702 together when it moves. A fixing plate 703 is fixedly connected to one side of the connecting plate 702. The connecting plate 702 and the fixing plate 703 are connected, and the fixing plate 703 can move together when the connecting plate 702 moves. A spring 705 is fixedly connected to the other side of the connecting plate 702. A sliding rod 704 is slidably connected inside the connecting plate 702. The two sliding rods 704 are connected to each other. The opposite ends are fixedly connected to the left and right sides inside the counterweight frame 601, respectively. The slide rod 704 is used to guide the movement of the connecting plate 702 and the fixed plate 703, and the support spring 705 can deform. The two fixed plates 703 are slidably connected to the left and right sides inside the counterweight block 602 on opposite sides.

The springs 705 are made of 65Mn spring steel.

[0037] Working principle: Before use, the counterweight 602 is installed in the counterweight frame 601. By moving the lever 701, the lever 701 drives the connecting plate 702 to move along the slide rod 704 and compress the spring 705. When the connecting plate 702 moves, it can drive the spring 705 to move together. Then, the counterweight 602 is placed in the counterweight frame 601. At this time, the counterweight frame 601 is outside the base plate 1. Then, the double-end motor 501 is started to lower the hook and the counterweight frame 601 enters the base plate 1.

[0038] After the hook descends and lifts the goods, the double-end motor 501 can be restarted to control the winding reel 8 to retract and lift the goods. While the double-end motor 501 controls the winding reel 8 to rotate, the other end also controls the small bevel gear 1 502 and small bevel gear 2 503 to rotate. After the small bevel gear 2 503 rotates, it will drive the linkage rod 504 to rotate together. The linkage rod 504 will control the large bevel gear 1 505 at the bottom to rotate. Thus, the large bevel gear 1 505 and the large bevel gear 2 506 mesh and drive each other, causing the threaded rod 507 to rotate. Then, the counterweight frame 601 will move along the threaded rod 507. According to the lifting height of the goods, the counterweight frame 601 moves to the corresponding position to keep the hoisting machine balanced.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
