Abstract
Description
Technical Field
[0001] This utility model relates to a hoisting device for equipment installation, and more particularly to a hoisting device that can realize the horizontal movement and vertical lifting of heavy objects. Background Technology
[0002] During the installation of power plant equipment, some heavy equipment needs to be moved from the lower floor slab to the installation location and then hoisted to the upper floor slab for installation. Since the plant workshop is already topped out, large hoisting equipment cannot be used, and the hoisting space is limited, so only winches can be used for hoisting. Some equipment is numerous and arranged in a row on the upper floor slab, with a row of holes for installation. The equipment needs to be moved sequentially to the corresponding lower floor slab and then hoisted into the corresponding holes on the upper floor slab for installation. For this type of equipment, the traditional hoisting method uses a fixed winch in conjunction with multiple pulley blocks for lifting and traction, with a circular pipe placed underneath during traction. This method has many drawbacks: it requires a huge amount of personnel, machinery, and time, and the leveling of the equipment is difficult to control. Furthermore, it is difficult to ensure safe and stable hoisting in confined spaces and environments, increasing wear on the wire ropes. How to safely and efficiently complete the installation of this equipment has become a problem that needs to be solved on the construction site. Summary of the Invention
[0003] This invention provides a hoisting device that enables stable horizontal movement and vertical lifting of heavy objects, achieving stable and safe movement and hoisting of heavy objects in confined environments.
[0004] This utility model solves the above technical problems through the following technical solution: A hoisting device capable of stable horizontal movement and vertical lifting of heavy objects includes a lower floor slab, an upper floor slab, and the heavy object. The upper floor slab has mounting holes for the heavy object. Movable supports are mounted on both sides of the mounting holes on the upper floor slab, and a winch is mounted on each of the movable supports. A fixed pulley support is mounted on the lower floor slab below the mounting holes, and a fixed pulley is mounted on the fixed pulley support. A tank chain trolley is mounted on the lower floor slab to the left of the fixed pulley support, and the heavy object is mounted on the tank chain trolley. A traction rope is connected to the hook of the winch, and the other end of the traction rope is connected to the tank chain trolley after passing through the fixed pulley.
[0005] The mobile support is equipped with a liftable column on its legs, and casters are connected to the lower end of the liftable column.
[0006] The beneficial effects of this utility model are as follows: (1) Due to the limited space for hoisting operations, the size and position of this utility model can be adjusted according to the working environment. The winch drives the wire rope to realize the vertical lifting of the heavy object and the horizontal traction of the equipment. The equipment can be placed on the pallet device. The pallet device is equipped with a tank chain, which has sufficient stability and load-bearing capacity to prevent overturning. The winch device cooperates with the pulley block to realize the horizontal traction of the equipment. (2) In order to avoid the phenomenon of the hoisting device shifting during the hoisting process due to the universal wheels being movable below, the mobile base is equipped with universal wheels with brake function during use. The universal wheels adopt an up-and-down telescopic adjustment device, which can effectively prevent the hoisting device from shifting and facilitate the overall movement and fixation of the device. (3) In order to avoid the phenomenon of the hoisting device slipping due to instability during the hoisting traction process, the winch is equipped with overload protection, emergency braking and anti-slip locking device during the hoisting traction process. It can be operated by hand-held remote control or wire control to realize the frequency conversion speed regulation function, ensuring the safety and stability of the hoisting device.

Winches 5 are mounted on the movable supports 4. A fixed pulley support 7 is mounted on the lower floor slab 1 below the equipment mounting holes 3. Fixed pulleys 8 are mounted on the fixed pulley support 7. A tank chain trolley 10 is mounted on the lower floor slab 1 to the left of the fixed pulley support 7. A heavy equipment 11 is installed on the 10; a traction rope 9 is connected to the hook 6 on the winch 5, and the other end of the traction rope 9 is connected to the tank chain trolley 10 through the fixed pulley 8; the traction rope 9 can be pulled by the hook 6 on the winch 5 to pull the tank chain trolley 10 and move the heavy equipment 11 smoothly to the bottom of the equipment installation hole 3; then, the traction rope 9 is removed, a lifting strap is tied to the heavy equipment 11, the hook 6 is connected to the lifting strap, and finally, the heavy equipment 11 is hoisted onto the upper floor slab 2 for installation by operating the winch 5.
[0009] After the hoisted equipment is installed, the liftable column 12 on the outrigger of the mobile support 4 is lowered, and the caster wheel 13 connected to the lower end of the liftable column 12 is placed on the ground. The mobile support 4 is then moved to the next installation position for the traction and hoisting of the next heavy object.
