Abstract

The utility model discloses a hook-relieving device of an automatic clamping lock. The utility model is composed of a suspension hook 1, a coupling shaft 2, a hook-relieving plate 3, a sliding shaft 4, a coupling shaft 5, a hook-relieving handle 6, a frame plate 7, an ear plate 8, a tension spring 9, etc., wherein the top end of the suspension hook 1 is positioned between the coupling shaft 5 and the sliding shaft 4; the hook-relieving plate 3 is positioned by the tension spring 9 so that the suspension hook 1 is clamped; the tension spring 9 is pulled so that a sliding shaft 5 slides over the top end of the suspension hook 1 which rotates so that a heavy article is relieved from the hook; the tension spring 9 is released, the hook-relieving plate 3 is reset, the suspension hook 1 is clamped again and the goal of the automatic clamping lock is realized. The utility model overcomes the defect of manual clamping lock of the existing hook-relieving device and increases work efficiency.

Description

A kind of tripping gear of automatic kayser

The utility model relates to the unhook machinery of weight in a kind of construction engineering, especially a kind of kayser tripping gear that rams base or piling usefulness weight.

In present building engineering construction, hang a tripping gear on the crane gear of being everlasting, the weight of slinging then, when lifting by crane certain altitude, pulling unhook handle makes weight break off relations, to ground compacting or piling.Whole process can be divided into 3 steps, (1) with tripping gear kayser (purpose be when be unlikely to behind the weight on the hook come off when carrying), (2) weight and lifting on the hook, (3) during to predetermined altitude pull-up unhook handle (utilizing manpower or machinery) kayser is sliped off, the weight whereabouts of breaking off relations.This process is wanted repeated multiple times in engineering, and a general machine-team is nearly inferior surplus in the of 800.Therefore design a kind of improved tripping gear, simplify above-mentioned steps, can increase work efficiency greatly.

The purpose of the utility model is to provide the tripping gear of the automatic kayser of a kind of energy, and it has overcome the deficiency of the artificial kayser of existing tripping gear, has omitted above-mentioned steps (1) in operation, and kayser can automatically reset after weight breaks off relations.

For reaching above-mentioned purpose, the technological scheme that the utility model is taked is: the utility model comprises suspension hook, otic placode, frame plate etc., suspension hook is actively connected on the frame plate by shaft coupling, frame plate and otic placode are fixedly connected, it is characterized in that: connect the unhook plate by shaft coupling on frame plate, an end of unhook plate is connected with slide-bar, and the other end is connected with the unhook handle, between unhook handle and the otic placode extension spring is arranged, the top of suspension hook is between the shaft coupling and slide-bar of unhook plate.

The utility model adopts above-mentioned structure, have following beneficial effect: the unhook plate of the utility model setting is connected on the frame plate by the shaft coupling activity, and extension spring is spacing with it, makes the suspension hook top between the shaft coupling and slide-bar of unhook plate, suspension hook is blocked, make it to pin and fix, during unhook, overcome tension spring, pulling unhook handle, slide-bar is slided cross the suspension hook top, suspension hook rotates under the gravity of weight, makes weight break off relations; Unclamp the unhook handle, under tension spring tension, unhook plate returning position is blocked the suspension hook top slide-bar once more, realizes the purpose of automatic kayser, both increases work efficiency, and is convenient to operation again, reduces labor intensity.

Below in conjunction with accompanying drawing and embodiment the utility model is done and to be described in further detail:

Fig. 1 is the utility model structural drawing.

In Fig. 1, the utility model is made up of suspension hook 1, shaft coupling 2, unhook plate 3, slide-bar 4, shaft coupling 5, unhook handle 6, frame plate 7, otic placode 8, extension spring 9 etc., wherein, frame plate 7 can be designed to the double plate structure of parallel symmetry, suspension hook 1 and unhook plate 3 are connected between two plates of frame plate 7 by shaft coupling 2, shaft coupling 5 respectively, the top of suspension hook 1 be the round inscribe that center of circle slide-bar 4 is slided with shaft coupling 5, extension spring 9 makes unhook plate 3 be positioned level, the pulling force of extension spring 9 can make suspension hook keep stable under the gravity of weight, its elongation amplitude can make suspension hook deviate from.

Claims
