The circumferential location structure comprises the crank shaft, the rolling arm, bolts, a roller wheel, a sealing element, a bearing and a gland bush of the bearing and is characterized in that the rolling arm is positioned at the inner side of a revolving body of the rotary forced-air cooler, one end of the rolling arm is connected with the shaft end of an inner spindle of the trolley by a key, the other end of the rolling arm is in contact with the lower surface of a rail press by the crank shaft and the roller wheel arranged on the crank shaft, the shaft end of the crank shaft is provided with a plane, a snap-gauge is in contact with the crank shaft by the plane, the circumferential direction of the snap-gauge is provided with a plurality of long circular holes, one side of the rolling arm is provided with a plurality of screwed holes of which the number corresponds to that of the long circular holes of the snap-gauge, snap-gauge bolts are screwed in the screwed holes, and the circumferential location structure keeps the trolley horizontal by rotating the crank shaft. When the crank shaft rotates to a certain proper position, the bolts of the crank shaft are screwed up, meanwhile, the crank shaft is locked by the snap-gauge, the snap-gauge bolts are screwed up, and the crank shaft is located. The utility model has convenient and quick operation and reliable structure.
Description
Technical field
The utility model technology relates to pelletizing air blast central cooler field, the circumferential location structure of bent axle in particularly a kind of pelletizing air blast circular cooler trolley roller arm.
Background technology
Chassis is the key member of pellet circular cooler.For chassis, remain the chassis level in the cooling zone of central cooler, to give, discharge zone overturns smoothly, resets, and can regulate easily and efficiently when in installation, maintenance and chassis running, occurring tilting, these all are very necessary.It can guarantee the normal operation of central cooler.Chassis roller arm is a key member of regulating and keep chassis level, the smooth loading, unloading material of assurance chassis.Crankshaft installed is equipped with roller in an end of roller arm on it, and the other end of roller arm links together axle in the chassis by key with chassis, and turning crankshaft can make chassis turn an angle together with interior axle, makes chassis maintenance level by this principle.Bent axle turns to the circumferentially reliable location of correct position, keeps level after can making the chassis charging, up to give, discharge zone.Bent axle was circumferentially fixing by the realization that tights a bolt in the past, and the problem that this structure often occurs is:
1) rigidity of roller arm is too big, and the pretension of nut can not make the roller arm produce enough distortion, produces relative motion between bent axle and roller arm, makes the adjacent stations workshop produce the displacement of short transverse.Therefore, qualified pelletizing will drain in the bellows below the chassis and enter the bulk cargo system, has strengthened the pressure that bulk cargo handles like this utilization rate of equipment and installations is reduced.
2) coefficient of friction is little between bent axle and roller arm, is not enough to produce enough moment of frictions and comes balance by the moment of the reinforced heavy phase of chassis deadweight for interior axle.The displacement that also can make the adjacent stations workshop produce short transverse, qualified pelletizing will drain in the bellows below the chassis, so also strengthened the pressure that bulk cargo handles and also made the utilization rate of equipment and installations reduction simultaneously.
3), also can be subjected to structure space too little and screw-down torque is too big, bad operation if strengthen bolt specification.
Summary of the invention
The purpose of this utility model provides the circumferential location structure of bent axle in a kind of pelletizing air blast circular cooler trolley roller arm of easy to operate, quick, reliable in structure.
The circumferential location structure of bent axle in the pelletizing air blast circular cooler trolley roller arm of the present utility model, comprise bent axle, roller arm, bolt, roller, seal, bearing, bearing gland, it is characterized in that described roller arm is positioned at central cooler revolving body inboard, one end of roller arm is connected in axle axle head in the chassis by key, the other end of roller arm is equipped with bent axle, and the roller that is installed on the bent axle contacts with the lower surface of pressing rail.
The axle head of described bent axle is provided with a plane, has a clamp to contact with described bent axle by this plane.
Described clamp is circumferentially opened a plurality of slotted holes, and a side of roller arm has a plurality of and the corresponding screwed hole of the quantity clamp slotted hole, is screwed with bolt in these screwed holes.
The circumferential location structure of bent axle in the pelletizing air blast circular cooler trolley roller arm of the present utility model, the roller arm is positioned at central cooler revolving body inboard, one end of roller arm is connected in axle axle head in the chassis by key, the other end of roller arm contact with the lower surface of pressing rail by bent axle and the roller that is mounted thereon, by turning crankshaft maintenance chassis level.When bent axle forwards a certain correct position to, tighten crank shaft bolt, block bent axle with clamp simultaneously, the tightening card crab bolt is located bent axle.
The circumferential location structure of bent axle is a kind of circumferential location structure of easy to operate, quick, reliable in structure in the pelletizing air blast circular cooler trolley roller arm of the present utility model.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the P of Fig. 1 is to view.
The specific embodiment
Further specify the specific embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the circumferential location structure of bent axle in the pelletizing air blast circular cooler trolley roller arm of the present utility model, comprise bent axle 1, roller arm 2, crank shaft bolt 3, roller 4, seal 5, bearing 6, bearing gland 7, it is characterized in that described roller arm 2 is positioned at central cooler revolving body inboard, one end of roller arm 2 is connected in the chassis axle head of axle 10 by key, and the other end of roller arm 2 contacts with the lower surface of pressure rail by bent axle and the roller 4 that is mounted thereon.
The axle head of described bent axle 1 is provided with a plane, has a clamp 8 to contact with described bent axle 1 by this plane.
Described clamp 8 is circumferentially opened a plurality of slotted holes, and a side of roller arm 2 has the corresponding screwed hole of quantity of the slotted hole of a plurality of and clamp, is screwed with clamp bolt 9 in these screwed holes.
The circumferential location structure of bent axle in the pelletizing air blast circular cooler trolley chassis roller arm of the present utility model, the roller arm is positioned at central cooler revolving body inboard, one end of roller arm is connected in axle axle head in the chassis by key, the other end of roller arm contact with the lower surface of pressing rail by bent axle and the roller that is mounted thereon, by turning crankshaft maintenance chassis level.When bent axle forwards a certain correct position to, tighten crank shaft bolt, block bent axle with clamp simultaneously, the tightening card crab bolt is located bent axle.
