Abstract
The invention discloses a locking device of a box-opening type power head. A connecting shaft is arranged on a lower box body, an upper box body is installed on the connecting shaft in a rotating mode, a pin base is fixed on the upper box body, a supporting base is fixed on the lower box body, a locking pin is installed in the supporting base in a sliding mode, the locking pin is matched with the pin base, the side wall of the locking pin is provided with a driving rack, the supporting base is hinged with a handle, a driving gear is arranged on the inner end portion of the handle, and the driving gear meshes with the driving rack. The locking device is simple and compact in structure, easy to operate, safe and reliable to lock, free from displacement and suitable for being popularized and applied in similar locking mechanisms.
Description
Technical field
The present invention relates to a kind of locking device of unpacking formula unit head, the invention belongs to engineering machinery (rig) technical field.
Background technology
The effect of unit head is the power that transmits through speed change, drives the drilling tool rotation and feed drilling tool in the hole, and drilling rod passes through therein, traditional structure is fixed, can't get out of the way the aperture of boring, rig must be retreated in the time of will extracting drilling rod in the work progress, in order to extract continuously drilling rod.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple and compact for structure, processing ease, locking is safe and reliable and the locking device of non-wiping unpacking formula unit head.
According to technical scheme provided by the invention, the locking device of described unpacking formula unit head, comprise upper box and lower box, at the added connecting axle that is provided with of lower box, described upper box is rotatably installed on the connecting axle, be fixed with key seat at upper box, be fixed with bearing at lower box, in bearing, be slidingly fitted with locking pin, locking pin cooperates with described key seat, and the sidewall of locking pin is provided with the driving tooth bar, is hinged with handle at bearing, inner end at handle is provided with driven wheel, driven wheel and the engagement of driving tooth bar.
Be fixed with gland at bearing, be provided with spring at gland, the other end of spring and described locking pin offset.
Offer stopper slot at locking pin, the length direction of stopper slot is consistent with the length direction of locking pin.
Offer the caging bolt hole at bearing, be bolted with caging bolt in the caging bolt hole, the bottom of caging bolt embeds in the described stopper slot.
The present invention controls moving up and down of tooth cylindrical pin by the handgrip of a fan profile of tooth, the engagement of the tooth of fanning by tooth when mobile and the tooth of tooth cylindrical pin prevents the displacement of tooth cylindrical pin, thereby firmly locking and opening function have been guaranteed, simple and reliable realization the switching function of lower box on the unit head, compare with the retaining mechanism that lacked the profile of tooth engagement in the past, the present invention is simple and compact for structure, processing ease, lock safe and reliable and be not shifted, be adapted at applying on the similar retaining mechanism.
