Description

Technical Field

[0001] This utility model relates to the field of heavy object lifting technology in building construction, and in particular to a heavy object lifting device for building construction. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings. In the construction of high-rise buildings, material hoists are usually used to transport building materials to the corresponding high-rise buildings for construction.

[0003] According to the search, the Chinese patent "A Building Construction Lifting Device" authorized announcement number "CN218491351U" achieves stable lifting of building materials through a base, lifting frame, lifting components, cargo rack and sliding rollers, thus ensuring the lifting efficiency of building materials.

[0004] In the aforementioned application, because both sides of the cargo rack are open, the cargo rack is prone to shaking during lifting, which could lead to the risk of building materials inside the cargo rack falling out, thereby increasing the risk of the lifting equipment lifting building materials.

[0005] Therefore, a heavy lifting device for building construction is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a construction heavy object lifting device to solve the above-mentioned problems, thereby improving the problem that the cargo rack is prone to shaking during lifting due to the open sides, which may lead to the risk of building materials falling out of the cargo rack.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a construction heavy object lifting device, comprising: a lifting frame, with two winches rotatably connected to the upper surface of the lifting frame, steel wire ropes wound around the surface of the winches, and a cargo rack fixedly connected to the bottom end of the steel wire ropes; and a sealing mechanism, comprising barriers hinged to the front and rear ends of the cargo rack, with a solid iron rod slidably connected to the lower end of the inner wall of the barriers, a spring fixedly connected to the top end of the solid iron rod, the top end of the spring fixedly connected to the lower end of the inner wall of the barriers, and the surface of the solid iron rod engaged with the lower end of the inner wall of the cargo rack. Through the spring and the solid iron rod, the barriers are locked onto the cargo rack, thereby achieving stable sealing of both sides of the cargo rack, thus preventing the risk of building materials falling during lifting and ensuring the safety of using the construction heavy object lifting device.

[0008] Preferably, a long rod is rotatably connected to the top of the solid iron rod, and a stop block is fixedly connected to the upper surface of the long rod. A limiting groove is formed at the upper end of the inner wall of the barrier. Through the long rod, the stop block, and the limiting groove, the upward movement of the long rod and the solid iron rod is locked, ensuring that the solid iron rod is stably locked into the shelf, thereby ensuring that the barrier stably seals the shelf.

[0009] Preferably, a shield is rotatably connected to the top of the barrier, and a coil spring is fixedly connected to the surface of the shield.

[0010] Preferably, a protective sleeve is fixedly connected to the top of the barrier, and the other end of the coil spring is fixedly connected to the inner wall of the protective sleeve. The protective sleeve, the barrier bar, and the coil spring together limit the upward movement of the long rod, ensuring the stability of the solid iron rod within the shelf.

[0011] Preferably, a limiting ring is fixedly connected to the top of the barrier, and a limiting block is fixedly connected to the upper surface of the long rod. The limiting ring and the limiting block limit the rotation angle of the long rod, ensuring that the blocking block accurately and stably abuts against the inner wall of the limiting groove.

[0012] Preferably, a handle is fixedly connected to the upper surface of the barrier.

[0013] Preferably, the lower end of the inner wall of the shelf is rotatably connected to rollers arranged in equal rows. These rollers reduce the friction during unloading of building materials from the shelf.

[0014] The beneficial effects of this utility model are:

[0015] 1. By using springs and solid iron rods, the guardrail is locked onto the cargo rack, thereby achieving stable sealing on both sides of the cargo rack. Compared to the existing cargo racks with open sides, this method seals off both sides of the cargo rack, thus preventing the risk of building materials falling during lifting and ensuring the safety of using construction heavy lifting equipment.

[0016] 2. The long rod, stop block, and limiting groove are used to lock the upward movement of the long rod and the solid iron rod. The protective sleeve, cover rod, and coil spring are used to limit the upward movement of the long rod, ensuring that the solid iron rod is stably locked into the shelf, thereby ensuring that the barrier stably seals the shelf.

[0022] 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.

[0023] In practical implementation: such as Figure 1-4 As shown, a construction heavy lifting device includes: a lifting frame 1, with two winches 2 rotatably connected to the upper surface of the lifting frame 1, wire ropes 3 wound around the surface of the winches 2, and a cargo rack 4 fixedly connected to the bottom end of the wire ropes 3; and a blocking mechanism 5, which includes barriers 51 hinged to the front and rear ends of the cargo rack 4, a solid iron rod 52 slidably connected to the lower end of the inner wall of the barriers 51, a spring 53 fixedly connected to the top end of the solid iron rod 52, the top end of the spring 53 fixedly connected to the lower end of the inner wall of the barriers 51, and the surface of the solid iron rod 52 snapped into the lower end of the inner wall of the cargo rack 4.

[0024] The winch 2 consists of an electric motor, drum, rolling bearings, brake, selector wheel, control cabinet, etc.

[0025] Electric motor: This is the most common power source for winch 2, providing power for its operation. It converts electrical energy into mechanical energy to drive the drum to rotate.

[0026] Drum: This is one of the key components of the winch 2, and it is usually made of cast iron or rolled and welded steel plate. The wire rope 3 is wound on the drum. When the drum rotates, the wire rope 3 winds around or unwinds, thereby lifting or lowering the load.

[0027] Rolling bearings: Installed at both ends of the drum, they support the rotation of the drum, reduce frictional resistance, and ensure the smooth and reliable operation of the drum.

[0028] Brakes: are an important guarantee for the safe operation of winch 2. They are used to quickly stop the drum from rotating when winch 2 stops working or needs to decelerate. Common brakes include electromagnetic brakes and hydraulic brakes.

[0029] Brake wheel: Mounted coaxially with the drum, it is the functional component of the brake that generates braking force. The surface of the brake wheel needs to have high hardness and wear resistance to ensure braking effect and service life.

[0030] Control cabinet: This is the control center of winch 2. It contains various control electrical components, such as contactors, relays, and fuses. Through the control cabinet, the winch 2 can be started, stopped, rotated forward and reversed, and its speed adjusted. The control cabinet usually has overload protection, short circuit protection, and leakage protection functions to ensure the safe operation of winch 2.

[0031] Both sides of the cargo rack 4 are rotatably connected to rollers, and the surface of the rollers contacts the surface of the lifting frame 1.

[0032] The lifting frame 1 is installed at a suitable location on the construction site using expansion bolts. When the height of the lifting frame 1 is low, the height of the lifting frame 1 can be adjusted by bolting or welding. The specific assembly height method of the lifting frame 1 is a well-known existing technology and will not be described in detail here. It can be selected according to the actual situation.

[0033] When transporting building materials to a high-rise building, pull one of the barriers 51 to open the front of the rack 4, allowing the building materials to be moved into the rack 4. After the materials are moved, push the barrier 51 to close the front of the rack 4. At this time, the elastic force of the spring 53 pushes the solid iron rod 52 down and engages with the lower end of the inner wall of the rack 4. Manually press the controller to the corresponding floor to automatically start the winch 2, which then winds up the wire rope 3. As the wire rope 3 winds up, it moves the rack 4 to the corresponding floor and then automatically stops lifting the rack 4, leaving it stationary. Open the barrier 51 on the side closest to the floor to move the building materials inside the rack 4 into the floor, facilitating the construction work of the high-rise building.

[0034] like Figure 4 As shown, a long rod 54 is rotatably connected to the top of the solid iron rod 52, a stop block 56 is fixedly connected to the upper surface of the long rod 54, a limit groove 55 is opened at the upper end of the inner wall of the barrier 51, a cover rod 57 is rotatably connected to the top of the barrier 51, a coil spring 58 is fixedly connected to the surface of the cover rod 57, a protective sleeve 59 is fixedly connected to the top of the barrier 51, the other end of the coil spring 58 is fixedly connected to the inner wall of the protective sleeve 59, a limit ring 511 is fixedly connected to the top of the barrier 51, a limit block 510 is fixedly connected to the upper surface of the long rod 54, and a handle 513 is fixedly connected to the upper surface of the barrier 51.

[0035] Pushing the limiting block 510 against the side of the limiting ring 511 causes the long rod 54 to rotate, which in turn drives the stop block 56 to rotate precisely against the inner wall of the limiting groove 55, loosening the cover rod 57. The elastic force of the coil spring 58 pushes the cover rod 57 to reset, so that the bottom of the cover rod 57 abuts against the top of the long rod 54.

[0036] like Figure 2 As shown, the lower inner wall of the shelf 4 is rotatably connected to rollers 512 arranged in equal rows. Both the rollers 512 and the guardrails 51 are made of 45 steel.

[0037] In use, this utility model involves pushing the cover rod 57, which in turn pushes the limiting block 510 to abut against the side of the limiting ring 511, causing the stop block 56 to rotate precisely to the appropriate position. This pulls the long rod 54 upward, thereby moving the solid iron rod 52 away from the shelf 4. Pulling one of the barriers 51 opens the front end of the shelf 4, allowing building materials to be moved into the shelf 4. After the material is moved, pushing the barrier 51 closes the front end of the shelf 4. At this time, the elastic force of the spring 53 pushes the solid iron rod 52 downward and engages it. At the lower end of the inner wall of the shelf 4, the push limit block 510 abuts against the side of the limit ring 511, causing the long rod 54 to rotate, which in turn drives the stop block 56 to rotate precisely and abut against the inner wall of the limit groove 55, loosening the cover rod 57. The elastic force of the coil spring 58 pushes the cover rod 57 to reset, so that the bottom of the cover rod 57 abuts against the top of the long rod 54. Manually press the controller to the corresponding floor, so that the winch 2 will start automatically, and then wind up the wire rope 3. After the wire rope 3 is wound up, the shelf 4 moves up to the corresponding floor.

[0038] It should be noted that the lifting frame 1, winch 2, wire rope 3, cargo rack 4, servo motor and rollers mentioned above are all components with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the servo motor can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art. 。
