The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.
Referring to fig. 1, 5 and 6, an embodiment of the present invention provides a method for removing obstacles from a driving mechanism of a sintering machine, including:
measuring and recording a first distance, a second distance and a third distance of different angles between the edge of an inner ring 21 and the edge of an outer ring 22 of the bearing 2;
the support frame 11 is arranged on one side of the gear box 3 close to the ground, and the distance between the gear box 3 and the ground is adjusted until the difference value between the first distance, the second distance and the third distance is smaller than d which is smaller than or equal to 1 mm.
According to the embodiment of the invention, the first distance, the second distance and the third distance of the edge of the inner ring 21 and the edge of the outer ring 22 of the bearing 2 in different angle directions are measured and recorded, so that the falling deformation amplitude of the gear box 3 affected by gravity after the bearing 2 is damaged can be recorded. The supporting frame 11 is arranged on one side of the gear box 3 close to the ground, and the gear box 3 can be supported to the position before the falling deformation by adjusting the distance between the gear box 3 and the ground, namely the position fixed on the star wheel shaft 4 through the bearing 2. According to the embodiment, when the difference value among the first distance, the second distance and the third distance is smaller than d according to comparison of the difference value among the first distance, the second distance and the third distance, wherein d is smaller than or equal to 1mm, the position of the gear box 3 before the gear box returns to the falling deformation can be judged, and the gear box 3 can be prevented from influencing the rotation of the gear 5.

The jack 13 is divided into a mechanical jack and a hydraulic jack, and the principles are different. In principle, hydraulic jacks are based on the pascal principle, i.e. the pressure is uniform throughout the liquid, so that in a balanced system the pressure exerted on a smaller piston is smaller, while the pressure exerted on a larger piston is also larger, thus keeping the liquid still. Different pressures at different ends can be obtained by the transfer of liquid, so that a change can be achieved. The common hydraulic jack uses the principle to achieve the force transmission. The mechanical jack adopts a mechanical principle, a handle is pulled repeatedly, a claw pushes a ratchet wheel to rotate in a clearance mode, a bevel pinion drives a bevel pinion to rotate a lifting screw rod, and therefore a lifting sleeve is lifted or lowered to achieve the function of lifting tension. But is not as simple as a hydraulic jack. In particular, mechanical jacks or hydraulic jacks are used, as the case may be.
In the embodiment, the jack 13 is arranged, so that the distance between the gear box 3 and the ground can be adjusted while the supporting effect on the gear box 3 is maintained.

Therefore, the obstacle-removing device 1 for the driving mechanism of the sintering machine, provided by the embodiment of the invention, has the advantages of simple structure, simplicity in operation and low cost, the sintering machine does not need to be stopped, the bearing 2 does not need to be replaced, the gear box 3 can be reset by adding the support frame 11, the gear 5 is protected by the gear box 3, and the influence on the rotation of the gear 5 is avoided.
In particular, the distance measuring device 12 of the present embodiment may be a laser range finder, an electromagnetic wave range finder, or an electro-optical range finder. The laser range finder is an instrument for measuring the distance to a target by using a certain parameter of modulated laser. The distance measuring method is divided into a phase method distance measuring instrument and a pulse method distance measuring instrument, the pulse type laser distance measuring instrument emits a pulse laser beam or a sequence of short pulse laser beams to a target when in work, a photoelectric element receives the laser beam reflected by the target, a timer measures the time from the emitting to the receiving of the laser beam, and the distance from an observer to the target is calculated. The phase-method laser range finder detects a distance by detecting a phase difference occurring when emitted light and reflected light propagate in a space. The laser range finder has light weight, small volume, simple operation, high speed and accuracy, and the error is only one fifth to one hundred times of that of other optical range finders.
Similarly, the electromagnetic waves in the microwave band or the light waves as the carrier waves are called microwave range finders or photoelectric range finders, respectively. The electromagnetic wave distance meter uses electromagnetic wave as carrier wave, after modulation, it is emitted from one end of measuring line, and reflected or transferred back from another end, and the time between emitted wave and echo is measured to measure distance. The photoelectric distance meter uses infrared light as carrier wave and is called infrared distance meter, the infrared distance meter uses fluorescence developed by gallium arsenide light emitting diode as carrier wave source, and the intensity of the emitted infrared ray can be changed with the intensity of the injected electric signal. Thus having the dual functions of a carrier source and a modulator. The gallium arsenide light emitting diode has the advantages of small volume, high brightness, low power consumption, long service life and continuous light emission, so the infrared distance meter is widely used. The electromagnetic wave distance measuring instrument has the advantages of high precision, rapid operation and small influence by weather and terrain.
