Description

Automatic clamping and placing pliers

Technical Field

The utility model relates to the field of industrial hoisting slings, in particular to an automatic clamping and placing clamp which realizes the whole process automation of clamping and placing of a clamp and does not need manual matching.

Background

The existing clamp is a widely applied practical tool, and the main structure is that 4 thick steel plates are connected into a telescopic prism through 4 shafts, wherein the lower ends of two lower steel plates are bent inwards to form a gripper, and an upper middle shaft is connected with a lifting rod hanging ring; in the working process, the lifting rope and the lifting rod pull the upper shaft to move upwards through the lifting ring, the distance between the upper shaft and the lower shaft of the prism is increased, and the distance between the left shaft and the right shaft is reduced in the same ratio, so that the clamped object is clamped by swinging inwards with the center shaft as the circle center below the gripper, the clamped object is tighter, the whole process does not depend on external force, and only depends on the self weight of the clamped object to clamp, so the automatic clamp is also called;

automatic clamps are divided into three categories:

1. the automatic clamp without lock is characterized in that an iron ring is welded on the outer side of a gripper, the gripper needs to be manually broken to ride on an object to be clamped when the automatic clamp starts to work, then the automatic clamp starts to lift, and the gripper is manually broken again when the automatic clamp stops working, so that the clamp is separated from the object to be clamped, and the automatic clamp is the laggard one in the technology;

2. the automatic clamp is locked manually, the upper side of the clamp body is provided with a hook, the hook is hooked on the lower shaft manually in a non-working state, so that the grippers are fixed in a separated state, after the automatic clamp starts to work, the grippers of the clamp body ride on a clamped object, the manual unlocking is carried out, the upper shaft and the lower shaft can move freely so as to start to work, when the work is finished, the lifting rope is loosened, the two grippers are separated automatically, at the moment, the clamp body can be moved only by manual locking, and the automatic clamp of the manual lock is slightly advanced compared with the automatic clamp without the lock;

3. the automatic locking clamp is characterized in that an iron plate with a notch is arranged on one side shaft of a clamp body, when the lifting rope is loosened after work is finished, the two sides of the side shaft move in place in the axial direction, wherein the side shaft without an iron plate strip just falls into the strip notch, the two side shafts are fixed on the maximum distance, a claw does not control a clamped object any more, the clamped body is smoothly separated from the clamped object, semi-automation is realized, namely manual unlocking is realized when work is started, and automatic locking is realized after work is finished, the clamp is the most advanced clamp at present, the force synthesis and decomposition principle is fully utilized, and the manual participation cannot be separated in operation, so that the technical problem which is not solved by clamp manufacturing enterprises for many years is solved; with the participation of manpower, the following disadvantages are brought:

firstly, the personnel cost is increased;

secondly, the working environment is poor, and people easily fall down and collide;

thirdly, the work that the clamped objects are dangerous goods such as high temperature, toxicity, explosion and the like which are not suitable for people to contact cannot be carried out;

fourthly, the working efficiency is low, time is occupied when someone operates, and in addition, the man-machine coordination and unification are difficult to realize, and the working hours are not wasted, for example, if the clamp body is in place, people such as a machine can not be obtained when the matched personnel are in place;

the utilization rate of the work site is low, firstly, enough personnel activity space is reserved in the work site, and secondly, whether the stacking height of the clamped objects meets the safety height which can be reached by personnel or not is considered at first.
