Adjustable building crane

Abstract

The invention discloses an adjustable building crane, comprising a base. The left upper end of the base is provided with a cab; the right upper end of the base is provided with a rotating mechanism; the output end of the rotating mechanism is provided with a support column; the right upper end of the support column is provided with a suspender; a guide wheel is arranged at the tail end of the suspender; a lifting rope is arranged on the guide wheel in a winding manner; the left end of the lifting rope is fixedly connected with a hoist; a hook is arranged at the lower end of the lifting rope; and the tail end of the bending hook of the hook is connected with a self-locking rod by a reset hinge. The adjustable building crane has a simple and reasonable structure; when a heavy object is hungon the hook, a traction rope is subjected to a pressing force, and then the self-locking rod is driven to rotate towards the inner side of the hook so as to play the self-locking action; a camera is arranged on the suspender above the hook; the action of the camera is to observe the situation below the lifting, so that an operator can grasp the surrounding sight clearly and conveniently; the safety of the device is improved; the switching between the carrying mode and the fixing mode of the device is realized; and the practicability of the device is greatly improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery and equipment, in particular to an adjustable construction crane. Background technique [0002] Construction machinery is the general term for machinery and equipment used in engineering construction and urban and rural construction. It is composed of stress machinery, decoration machinery, high-altitude operation machinery and other machinery. [0003] Cranes are indispensable logistics and transportation equipment in modern economic construction to improve material handling conditions, realize automation and mechanization of the production process, and increase labor productivity. With the continuous expansion of the scale of human production activities and the rapid development of the national economy, the requirements for mechanization and automation are increasing The height is getting higher and higher, and the crane technology corresponding to this is also developing at a hi...

[0003] Cranes are indispensable logistics and transportation equipment in modern economic construction to improve material handling conditions, realize automation and mechanization of the production process, and increase labor productivity. With the continuous expansion of the scale of human production activities and the rapid development of the national economy, the requirements for mechanization and automation are increasing The height is getting higher and higher, and the crane technology corresponding to this is also developing at a high speed, and the scope of use is becoming wider and wider. When the existing crane is operated by the operator, it may be blocked by objects such as lifting objects, buildings, etc., and the operator It is impossible to fully observe the situation in the operating area of ​​the equipment, and the hooks of some cranes are not equipped with self-locking devices, which is prone to safety hazards
