Self-balancing iron driller

Abstract

The invention relates to a self-balancing iron driller which comprises a lifting mechanism, an expansion swinging mechanism and an operation tool; one side of the operation tool is connected with a hinged connecting block; and the expansion swinging mechanism is movably connected between the lifting mechanism and the hinged connecting block. The self-balancing driller also comprises a balance mechanism; the balance mechanism comprises a balance wheel, a balance block and a balance rope; the balance wheel is arranged on the top end of the lifting mechanism; the balance block is suspended on one side of the lifting mechanism; and one end of the balance rope is connected onto the hinged connecting block or the operation tool, and the other end of the balance rope passes around the balance wheel and is connected onto the balance block. The self-balancing iron driller effectively reduces the problem of the gravity center deviation of a device, reduces the overturning risk of the device, effectively reduces the stress of a component, benefits the compact design of the component, effectively improves the stability of the mechanism, benefits to miniaturized design of the component device, and can greatly save the manufacturing cost.

Description

Technical field [0001] The invention relates to a mechanical equipment, in particular to an automatic balancing iron driller. Background technique [0002] With the development of drilling automation technology, the manual operation of loading and unloading drilling tools on the drilling platform is gradually being replaced by automated equipment, of which iron drills are one of the main mechanical equipment. [0003] At present, most iron drillers use a multi-bar mechanism to realize the movement of the drill floor tongs, which are working tools. The components of the tongs are relatively large and heavy. They need to be placed at the end of the moving mechanism, resulting in relatively large forces on the hinge points of the components. . In order to ensure the smoothness of the movement of the pliers assembly, all components must have sufficient bearing capacity, and have the strength and rigidity to prevent the mechanism from subverting. Therefore, the design of the components...

Problems solved by technology

[0003] At present, most iron drillers use a multi-rod mechanism to move the drill floor tongs, that is, the working tools. The components of the tongs are relatively large and heavy, and they need to be arranged at the end of the moving mechanism, resulting in relatively large forces on the hinge points of the components.

In order to ensure the smooth movement of the tong assembly in the moving mechanism, all components must have sufficient load-bearing capacity and have the strength and rigidity to prevent the mechanism from overturning. Therefore, the design of the components is relatively large, cumbersome, and expensive, which is not conducive to popularization and application.
