Abstract
The utility model relates to an anti-slip device for a coke pot of a coke dry quenching elevator. The anti-slip hook device is designed against more serious accidents caused by the situation that a heavy coke pot can cause slip during pulling of a winch of the elevator. The anti-slip device for the coke pot of the coke dry quenching elevator, disclosed by the utility model, comprises leading supports (14) mounted on the two sides of a support of the elevator, wherein a group of stagnation blocks (8) are respectively mounted on the leading support on each side, a trigger block (10) is mounted below each stagnation block, the trigger blocks are connected with a power mechanism (12) through a transmission mechanism (11), and the power mechanism is connected with a control and transmission device (13). The anti-slip device disclosed by the utility model is used for ancillary facilities for the coke dry quenching elevator.
Description
Technical field:
The utility model relates to the anti-hook device that slips of a kind of dry quenching hoisting machine coke jar, belongs to machinery and Electrical Control Technology field.
Background technology:
Dry Quenching Technology is at China's coal chemical enterprise widespread use, shown in accompanying drawing 1-2, lift is caught burnt jar that red Jiao is housed by suspender, and the elevator that is contained in the lift top can be sling suspender and burnt jar by wireline, arrives the dry coke quenching predetermined position and bleeds off the red defocusedly more burnt jar of sky is put down.Suspender and burnt jar are in lifting process, and the hanger on it slides in support and prevent that burnt jar occurs rocking in lifting process.The braking of lift in descend parking or hovering process is mainly by provide the band-type brake of the electric system of power to be provided by lift.Because lift work load is heavier, burnt jar changes in weight is bigger simultaneously, to having relatively high expectations of band-type brake, if band-type brake can not play braking action by expection, under the situation that lift is short of power or power breaks down, heavy burnt jar will spur the lift elevator and glide by (slide hook), cause comparatively serious security incident, equipment producer requirement equipment applying unit especially will be strengthened the maintenance to the band-type brake system for this reason, but still has the generation of lift slide hook accident.
The utility model content:
The purpose of this utility model is that the problem at above-mentioned existence provides a kind of dry quenching hoisting machine coke jar the anti-hook device that slips, and avoids or reduces because lifting mechanism slips the loss that the hook accident produces, and effectively guarantees the safety of coke dry quenching hoister work.
Above-mentioned purpose realizes by following technical scheme:
The anti-hook device that slips of dry quenching hoisting machine coke jar, comprise the guide support that is installed in lift support both sides, one group of retardance piece is installed respectively on the described guide support of every side, each described retardance piece below is installed and is triggered piece, described triggering piece connects actuating unit by transmission rig, and described actuating unit connects control and transmission mechanism.
The anti-hook device that slips of described dry quenching hoisting machine coke jar, described retardance piece is installed on the described guide support by turning axle.
The anti-hook device that slips of described dry quenching hoisting machine coke jar, the triggering piece in the guide support of every side is cascaded by cable.
Beneficial effect:
1. the hook accident when taking place to slip for burnt jar in the utility model, started the triggering mechanism of means of retardation by the Controlling System automatic or manual, the means of retardation that originally relies on self gravitation to be placed in internal stent is ejected support, with the hanger generation grazing in the downslide, the downslide that slows down and even block burnt jar.The position of retardance piece is moved, thereby the retardance piece on next door is ejected support, provide support to each retardance piece simultaneously, avoid blocking piece and be subjected in the hanger collision withdrawal support.Avoid or reduce because lifting mechanism slips the loss that the hook accident produces, effectively guarantee the safety of coke dry quenching hoister work.It is simple in structure simultaneously, is conducive to installation, maintenance and the inspection of equipment.
2. the utility model is simple in structure, and is with low cost, makes and easy for installation, is conducive to simultaneously existing coke dry quenching hoister system is transformed, and the safety of protecting lift work is had good effect.

Embodiment:
Come the utility model is described further below in conjunction with accompanying drawing:
Embodiment 1:
The anti-hook device that slips of dry quenching hoisting machine coke jar, comprise the guide support 14 that is installed in lift support both sides, one group of retardance piece 8 is installed respectively on the described guide support of every side, each described retardance piece below is installed and is triggered piece 10, described triggering piece connects actuating unit 12 by transmission rig 11, and described actuating unit connects control and transmission mechanism 13.As shown in Figure 3-4, guide support is installed two one group along the direction of burnt jar lifting, have two groups, be installed in the two ends of lift derrick respectively, along the support above-below direction hanger means of retardation be installed successively, and consistent with retardance piece mounting height in other supports.The retardance piece can be made of the higher material of toughness such as rubber, under normal circumstances relies on self gravitation can be captured in internal stent, can move on to the support outside around the axle center under the effect of external force.Triggering mechanism is installed in the inboard of every support equally, triggers piece and installs near each retardance piece, and actuating unit can move by transmission rig and trigger piece to the position of setting, and under the effect that triggers piece, the retardance piece moves on to the support outside.Trigger piece simultaneously and provide support to each retardance piece, avoid blocking piece and be subjected in the hanger collision withdrawal support.Means of retardation in the present embodiment device and trigger device can be retrofited according to actual needs, and especially its contour structures of means of retardation and material use range are wider, and manufacturing and replacement are all very convenient.
Embodiment 2:
The anti-hook device that slips of described dry quenching hoisting machine coke jar, described retardance piece is installed on the described guide support by turning axle 9.
Embodiment 3:
The anti-hook device that slips of described dry quenching hoisting machine coke jar, the triggering piece in the guide support of every side is cascaded by cable.
Working process:
As shown in Figure 5, the slide hook appears when burnt jar loses damping force, hanger along support suddenly to lower slip, device is by (manually) triggering automatically, triggering piece is moved upwards up to desired location rapidly and will blocks piece and shift out support, hanger will block piece with these and bump and rub, and potential energy is by mass consumption, and a burnt jar falling velocity obtains obvious suppression or even stops.
