Abstract
The invention relates to a self-locking, safe and steam-powered gripping hook that is used for slinging essentially consisting of a hook post (1), a hook seat (2), a pin (3), a peg (4), a post (5), a spring (6), a support shell (7), a beam (8), a sliding seat (9), a bearing seat (10), a hook ring (11), a cylinder (12) and a bracket (13). The opening and closing of the hook ring is controlled by the cylinder. When the hook spring is loaded, the spring is compressed with gravity, and the sliding seat moves upwards with the beam correspondingly, then the beam is hooked and the mechanism is flatly locked up and can not be unlocked before unloaded, thereby effectively preventing the falling of the load caused by artificial misoperation and resulting in a safer, more reliable and efficient system. When in use, the produce can effectively shorten the lifting and landing time of the drilling tool system, thereby the construction period is shortened and the work efficiency of a drilling rig is improved.
Description
Technical field:
The present invention relates to engineering driller, shaft drilling machine lifting means technical field, especially a kind of self locking safety pneumatic clip hook that is used to lift by crane.
Background technology:
Clip hook is the critical piece of engineering driller, shaft drilling machine, the lifting that is usually used in drilling rod and lower drilling tool system with transfer.Rig is the bit force more complicated in drilling process, operating mode is abominable, drill bit needs often to change cutter, in order to prevent that the borehole wall from shrinking landslide, all need frequent lifting, transfer drilling rod and drill bit, adopt common lifting tool to need the staff closely to operate, increased danger and operating time, greatly reduce operating efficiency.
Summary of the invention:
For solving the problem that prior art exists, the purpose of this invention is to provide a kind of safe and reliable boom hoisting, a kind of self locking safety pneumatic clip hook that is used to lift by crane.This clip hook adopts cylinder control folding, remote control, and the mechanical linkage self-locking can't be opened during load, prevents maloperation.
In order to realize the foregoing invention purpose, the present invention adopts following technical scheme:
Described a kind of self locking safety pneumatic clip hook that is used to lift by crane, it installs mainly by shank, the hook seat, bearing pin, pin, bar, spring, support housing, crossbeam, slip base, bearing support, shackle, cylinder and carriage are formed; Shank is lifted in the mechanism moving up and down, the lower end of shank is connected with bar by screw thread, the lower end of bar is connected with bearing support by screw thread, the both sides device of bearing support has the slip base that has hook, bearing in slip base and the bearing support connects, slip base is installed in the support housing, bar in the support housing is provided with spring, support housing is assembled with the hook seat by bolt, by bearing pin and pin shackle and cylinder are installed respectively on the hook seat, shackle is connected with piston rod, the shackle bottom be two semi-circular, be installed with carriage on the bar of shackle, carriage is provided with crossbeam.
Described a kind of self locking safety pneumatic clip hook that is used to lift by crane, the principle of its self-locking is: after cylinder control shackle is embraced weight, the top jigger gaff, shank drives on bar and the slip base and moves, spring is compressed, and the hook on the slip base hooks crossbeam, and moves on the drive crossbeam, be located on the shank until hook, mechanism is locked, by pretensioned spring, makes the hook on hook seat drive shackle and the crossbeam disengaging slip base, folding with cylinder control shackle, after shackle was embraced load, spring moved on the relative crossbeam of slip base in the action of gravity lower compression, crossbeam is hooked, and can't open before the removal load.
Owing to adopted above technical scheme, the utlity model has following good effect:
Described a kind of self locking safety pneumatic clip hook that is used to lift by crane, it is in the lifting process, hundreds of tons drilling system drops if weigh, and not only wracks equipment, more threat to life, and clip hook adopts cylinder control folding, remote control, the mechanical linkage self-locking can't be opened during load, prevented maloperation, made machine system more safe, reliable, efficient.Adopt this product, can effectively shorten hoisting and transferring the time of drilling system, thereby the reduction of erection time is improved the rig operating efficiency.
