A small hoisting machinery device for construction

Abstract

The invention discloses a small hoisting mechanical device for construction. The small hoisting mechanical device comprises a device base, wherein a mounting base and a toolbox are arranged at one side of the upper part of the device base; a control device and a lifting motor are arranged on the mounting base; the lifting motor is matched with a small chain wheel; the small chain wheel is matched with a big chain wheel arranged on a rope deploying and retracting device through a chain; one side of the rope deploying and retracting device is provided with a rotary motor; a pinion arranged on the rotary motor is engaged with a big gear arranged on a rotating stand; an inclined multi-stage oil cylinder and a transverse multi-stage oil cylinder are arranged on the rotating stand; the inclined multi-stage oil cylinder is connected to a slide wheel device; and the transverse multi-stage oil cylinder is connected to a drag hook. The small hoisting mechanical device for construction disclosed by the invention has an automatic shutdown protection function and an alarm function, is safe and convenient to use, and is capable of directly hoisting heavy objects into a building, so that a worker does not need to take a risk of pulling the heavy objects into the building from a window, and therefore, the potential safety hazards are avoided, and the safety of a construction worker is guaranteed.

Description

technical field [0001] The invention relates to the field of hoisting machinery, in particular to a small construction hoisting machinery device. Background technique [0002] In building construction or other construction sites, the frequency of use of hoisting machinery is very high. When lifting heavy objects, it is almost all done by hoisting machinery. The use of hoisting machinery provides great convenience for construction workers. , which saves the physical strength of workers and improves the construction efficiency. At present, when lifting heavy objects on construction sites, hoists are often used as hoisting machinery, but there are many disadvantages in the use of hoists. After the hoist lifts up heavy objects, it will Because the hoist is installed inside the building, the heavy objects lifted vertically are likely to scratch the walls of the building during the lifting process, and when the heavy objects are hoisted, it is still necessary for the staff to lift...

[0002] In building construction or other construction sites, the frequency of use of hoisting machinery is very high. When lifting heavy objects, it is almost all done by hoisting machinery. The use of hoisting machinery provides great convenience for construction workers. , which saves the physical strength of workers and improves the construction efficiency. At present, when lifting heavy objects on construction sites, hoists are often used as hoisting machinery, but there are many disadvantages in the use of hoists. After the hoist lifts up heavy objects, it will Because the hoist is installed inside the building, the heavy objects lifted vertically are likely to scratch the walls of the building during the lifting process, and when the heavy objects are hoisted, it is still necessary for the staff to lift the heavy objects from the rope reel frame outside the building. Pulling up to the building has potential safety hazards, and the hoisting machinery currently used lacks an overload alarm device, which is prone to dangerous accidents due to mechanical overload when lifting heavy objects
