Abstract
The utility model discloses a hoisting mechanism with a standby power and relates to the hoisting mechanism of a hoister. The hoisting mechanism with the standby power solves the technical problem that potential safety hazard is existed in the existing hoisting mechanism when power is suddenly off and can not be supplied timely. The hoisting mechanism with the standby power comprises two high-power motors, a planetary reducer and two coiling cylinders. The two high-power motors respectively drive the planetary reducer through couplings to drive the two coiling cylinders to rotate at a rated rotate speed. The hoisting mechanism with the standby power is characterized in that a standby power device is additionally arranged on an input shaft of the planetary reducer, wherein a manual operation clutch, an accident reducer, a standby brake, a standby coupling and a low-power motor are sequentially connected to form the standby power device. The hoisting mechanism with the standby power is suitable for the hoisting mechanism driven by the low-power motor to finish the accident management when the power is off.
Description
Technical field
The utility model relates to the lifting mechanism of gig, particularly a kind of lifting mechanism with power for subsequent use.
Background technology
In the gig lifting mechanism commonly used, for improving reliability and capacity rating, adopt planetary reduction gear now more, two power input shafts are arranged, connect respectively two motors and drg; A power take-off shaft, two ends connect respectively two double crosslinking drums.When a motor has fault, but another motor lead agency is with half continuous firing of command speed.Like this, the reliability of lifting mechanism and capacity rating are all fine.But in the situation that often has a power failure suddenly and can't in time recover, urgent need will be parked in burnt tank in midair, that load red Jiao of high temperature and be transported to the dried stove that puts out, and diesel powerplant for subsequent use can't drive arbitrary motor of lifting mechanism because power is less, as can't in time disposing the burnt tank that loads red Jiao of high temperature, can produce serious consequence.
Summary of the invention
The purpose of this utility model is intended to overcome the shortcoming of prior art, a kind of lifting mechanism with power for subsequent use is provided, solve gig lifting mechanism now commonly used in the situation that has a power failure suddenly and can't in time recover, diesel powerplant for subsequent use can't drive arbitrary motor of lifting mechanism because power is less, have the technical matters of potential safety hazard.
The utility model is achieved through the following technical solutions.
A kind of lifting mechanism with power for subsequent use, comprise: two the second coupler between two heavy-duty motors, two drgs, two the first coupler, planetary reduction gear, two reels and reel and retarder, two high power motors drive planetary reduction gear by the first coupler respectively, and planetary reduction gear drives two reels and turns round with rated speed of rotation; It is characterized in that: on the input shaft of described planetary reduction gear, install the stand-by power unit that a cover is connected to form successively by manual clutch, accident retarder, drg for subsequent use, coupler for subsequent use and low-power machine additional.
The utility model compared with the prior art, because on the basis of the lifting mechanism that contains planetary reduction gear, installed a cover stand-by power unit additional, during normal operation, manual clutch is in released state, worked simultaneously or one of them work by two high power motors, with movable reel with rated speed of rotation or with half running of rated speed of rotation; When system power supply has fault to power, after manually manual clutch being closed, can start diesel powerplant for subsequent use, drive low-power machine, so with movable reel with a lower rotation speed operation, finish accident handling.
The utility model is applicable to all need to be when power fail, can finish at short notice in the system of one or two working cycle by small-power power, low-power machine lead agency, need to be specially adapted in the dry quenching system of high reliability, can be when main power source has fault, the lifting mechanism of gig can utilize diesel powerplant for subsequent use to drive low-power machine work, the loading weight during lead agency disposal accident.The utility model also is applicable to other and often has a power failure, needs in the lifting mechanism of low-power disposal accident for subsequent use.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The utility model is further described by preferred embodiment below in conjunction with accompanying drawing.
The specific embodiment
As shown in Figure 1, a kind of lifting mechanism with power for subsequent use, comprise: two the second coupler 6 that two heavy-duty motors 1, two drgs 2, two the first coupler 3, planetary reduction gear 4, two reels 5 and reel 5 and retarder are 4, two high power motors 1 drive planetary reduction gear 4 by the first coupler 3 respectively, and planetary reduction gear 4 drives two reels 5 and turns round with rated speed of rotation; On the input shaft of described planetary reduction gear 4, install the stand-by power unit that a cover is connected to form successively by manual clutch 7, accident retarder 8, drg for subsequent use 9, coupler for subsequent use 10, low-power machine 11 additional.
Working process of the present utility model:
During normal operation, manual clutch 7 is in released state, is worked simultaneously by two high power motors 1, turns round with rated speed of rotation by the first coupler 3, planetary reduction gear 4 band movable reels 5; When wherein a high power motor 1 has fault, another motor 1 by the first coupler 3, planetary reduction gear 4 with movable reel 5 half running with rated speed of rotation.When system power supply has fault to power, first by manually manual clutch 7 being engaged, then start diesel powerplant for subsequent use, drive low-power machine 11, by coupler 10 for subsequent use, accident retarder 8, manual clutch 7, planetary reduction gear 4, and then with movable reel 5 with a lower rotation speed operation, finally finish accident handling.
