Description
Technical field：
A kind of device of the spacing power down failure of anti-grab-crane weight is the utility model is related to, belongs to plant equipment technology neck
Domain.
Background technology：
Grab-crane is industry spot common equipment, for realizing the transhipment of material in three dimensions, is pushed up positioned at driving
The raising and lowering of two loose drums driving steel wire rope on portion's track, steel wire rope lower end is connected to capture the grab bucket of material, volume
The different manner of execution of cylinder control the rising, decline and the loading to material and unloading of grab bucket.The lifting and decline of grab bucket
It is that must control in certain safe range, particularly its lifting height needs especially limitation, and grab bucket otherwise just occurs
Rush to summit accident.In use, weight is spacing can prevent grab bucket from continuing to rise and cause to rush to summit, and be grab-crane lifting mechanism
Ultimate safety guard.The conventional counterweight limit device of industry spot is mainly by limit switch, Sling Rope and weight at present
Composition, when grab bucket rises to extreme position, grab bucket upper end cover hits weight, acts limit switch by Sling Rope, drives a vehicle
Elevator powers off, and grab bucket stopping continues to rise.
In practice, weight safety guard frequently malfunctions, and fault rate is higher for production scene, causes driving continually anxious
Stop, production operation efficiency is had a great influence, electromechanical equipment all brings certain damage.It is the discovery that by meticulous inspection due to volume
During cylinder steel wire rope action, the spacing Sling Rope of weight under being active is constantly among rocking, reel main rope
Friction is produced with the spacing Sling Rope of weight, causes hoist cable fracture of rope weight to drop, triggers tup to act, weight is spacing normally closed tactile
Point disconnects, and driving elevator powers off suddenly.It is unexpected that malfunction influence the continuity of production often, and there is also tight for the weight to drop
Weight potential safety hazard.Weight is installed in the base angle position of reel, place narrow space and greasy dirt is more, is brought to service work
Inconvenience, resume operation at least needs 1-2 hours every time, and maintenance cost and time are very big, are had undesirable effect to production.Cause
This, there is provided a kind of reasonable in design, stable working, safe and reliable, service life is long, protection grab-crane is without damage, is easy to tie up
The weight limiting and protecting device of shield is necessary.
Utility model content
The purpose of this utility model is to provide a kind of anti-grab-crane weight spacing power down event for above-mentioned problem
The device of barrier, the weight that grab-crane is without damage, is easy to maintenance, stable working, safe and reliable, service life can be protected
It is long.
Above-mentioned purpose is achieved through the following technical solutions：
A kind of device of the spacing power down failure of anti-grab-crane weight, including the limit switch being connected with weight tup, institute
The limit switch connection fixing base stated, described fixed seat downside are provided with spring spool, set inside described spring spool
There is spring, the upper and lower ends of described spring are respectively arranged with upper end cover and bottom end cover, and described bottom end cover is connected by connecting rod
Anticollison block, hook, weight tup of the described hook described in by drawstring connection are provided with described upper end cover.
The device of the described spacing power down failure of anti-grab-crane weight, described limit switch outside set limited location to open
Close containment vessel.
The device of the described spacing power down failure of anti-grab-crane weight, the internal height of described spring spool are more than institute
The spring stated and upper end cover and bottom end cover height sum.
Beneficial effect：
The utility model can effectively avoid scratching of the reel steel wire ropes to the spacing steel wire rope of weight, it is ensured that grab bucket can
Rise be raised to the limit position when, immediately stop continue to rise, good limit effect.Brake apparatus part is using setting spring side in sleeve
Formula, can reduce grab bucket rise with anticollison block collision caused by impulsive force, device damage caused by when being effectively reduced collision,
Extension device service life, it is ensured that grab-crane traveling comfort and security.

Embodiment
With reference to embodiment, the utility model is furtherd elucidate, it should be understood that following embodiments are only used
In explanation the utility model rather than limitation the scope of the utility model.
A kind of device of anti-spacing power down failure of grab-crane weight described in the present embodiment, including with weight tup 13
The limit switch 11 of connection, the described Action Button of limit switch 11 are connected with the power switch of lifting motor, can be direct
The power supply of motor is cut off, lifting motor is stopped, prevents grab bucket from continuing to rise, accident of rushing to summit, limit effect
It is good.Described limit switch connection fixing base 15, described fixed seat downside are provided with spring spool 21, described spring spool
The inside is provided with spring 22, and the upper and lower ends of described spring are respectively arranged with upper end cover 23 and bottom end cover 24, described lower end
Lid connects anticollison block 27 by connecting rod 26, is provided with hook 25 on described upper end cover, described hook is connected by drawstring 14
Described weight tup.
The device of the described spacing power down failure of anti-grab-crane weight, described limit switch outside set limited location to open
Close containment vessel 12.Limit switch containment vessel 12 is made using galvanized sheet, outside limit switch 11, is realized in outdoor
The protective action of the limit switch to be worked under state；
The device of the described spacing power down failure of anti-grab-crane weight, the internal height of described spring spool are more than institute
The spring stated and upper end cover and bottom end cover height sum.
The course of work：
When the grab bucket of grab-crane rises to specified altitude assignment, grab bucket collides with anticollison block 27, in the work of impulsive force
Under, anticollison block 27 promotes the spring 22 of brake apparatus 02 to act, while the 23 of upper end cover move up, and make place by connecting rod 26
Drawstring 14 under tensioning state is in relaxation, and then triggers weight tup 13 and act, and weight tup 13 promotes limit switch 11
Action, cuts off motor power, and grab bucket stopping continues to rise.The utility model has reasonable in design, stable working, braking effect
It is good, service life is long, protection grab-crane is without damage, the advantages of being easy to safeguard.
