Abstract

The utility model relates to a double-hook tripper comprising a hanger plate, wherein a first hook and a second hook are symmetrically hinged on the lower end of the hanger plate; the upper end of thefirst hook is hinged with one end of a lever, and a roller and a limited wire are arranged on the other end of the lever; and the roller can roll in a rolling way arranged on the upper end of the second hook. The utility model has a simple structure; and a hammer bottom can be kept in parallel with the horizon when a hammer ram falls down, which can largely improve the effect of the hammer ram.

Description

The double hook detacher

Technical field

The utility model relates to a kind of double hook detacher.

Background technology

Ram strong that traditional tripping gear is that single hook breaks off relations (seeing Figure of description 1) in the engineering, hook is mentioned hammer ram by unidirectional frictional force, when dropping hammer, the moment of breaking off relations single hook and hammer handle between the stressed f of friction be unidirectional (asymmetric).Under this frictional force effect, hammer handle rotating certain angle α when hammer ram falls, thus cause hammer ram bottom surface and ground line to form certain angle, effect is rammed in influence.

Summary of the invention

The purpose of this utility model is to address the above problem and provide a kind of simple in structure, and hammer ram can remain the hammer end with horizontal parallel when falling, can improve the double hook detacher of hammer ram effect greatly.

The utility model solves the problems of the technologies described above the technical scheme that is adopted:

It comprises boatswain chair, and boatswain chair lower end symmetry is hinged with first hook and second hook, and the upper end and lever one end of first hook are hinged, and the other end of lever is provided with roller and spacing rope, rolls in the raceway that roller can be provided with in the upper end of second hook.

Compared with prior art, the utility model has been obtained following technique effect:

1, this utility model is simple in structure, the frictional force f between unhook moment double hook and hammer handle ₁, f ₂Be bi-directional symmetrical, under the effect of balance frictional force, hammer ram can remain the hammer end with horizontal parallel when falling, give full play of and ram effect.

Wherein: 1-hammer handle, 2-first hook, 3-first hinge, 4-second hinge, 5-boatswain chair, the spacing rope of 6-, 7-roller alive, 8-lever, 9-raceway, 10-second hook.

The specific embodiment

Further specify embodiment of the present utility model below in conjunction with accompanying drawing.

Embodiment 1

Referring to Fig. 2-3, a kind of double hook detacher, it comprises boatswain chair 5, the boatswain chair lower end is hinged with first hook, 2 and second hook 10 by first hinge, 3 symmetries, the upper end of first hook and lever 8 one ends are hinged by second hinge 4, the other end of lever is provided with roller 7 and spacing rope 6, rolls in the raceway 9 that roller can be provided with in the upper end of second hook.Certainly because first hook, 2 and second hook, 10 bilateral symmetry also can allow the upper end and lever one end of second hook hinged, roller rolls in the raceway that the upper end of first hook is provided with.

Operating principle of the present utility model:

Crane hook (being connected with the detacher boatswain chair) is placed on detacher near the hammer handle 1 of hammer ram, after biting hammer handle 1 by operating personnel with double hook, this moment, highly spacing rope 6 relaxed, lever 8 falls under gravity on first hook, 2 and second hook, 10 shoulders, its left end and first hook, 2 outer shoulders are hinged, the right is against second by roller 7 and links up with 10 outer shoulder raceway 9 places, and double hook can not be opened, and keeps closing up state (biting hammer handle 1).

When crane is promoted to predetermined altitude with detacher, spacing rope 6 is with tensioning, until an end of mentioning lever 8, roller 7 is upwards rolled in raceway 9 until breaking away from raceway 9, and this moment, first hook, 2 and second hook 10 lost the constraint of lever 8, under the hammer ram action of gravity, double hook opens simultaneously, discharge hammer handle 1, the hammer ram free-falling is implemented to ram.Because the frictional force of double hook detacher on unhook momentary action and hammer handle becomes a pair of equal and opposite in direction, the equilibrant force (f that direction is opposite ₁, f ₂), make the movement of falling object of hammer ram not be subjected to first hook 2 and second to link up with the influence of 10 directions of motion, steadily fall.

Protection domain of the present utility model is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and not break away from scope and spirit of the present utility model the utility model.If these changes and distortion belong in the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and is out of shape interior.

Claims

1. double hook detacher, it comprises boatswain chair (5), it is characterized in that: boatswain chair lower end symmetry is hinged with first hook (2) and second hook (10), the upper end and lever (8) one ends of first hook are hinged, the other end of lever is provided with roller (7) and spacing rope (6), rolls in the raceway (9) that roller can be provided with in the upper end of second hook.
