Abstract
The utility model relates to a roller way chain tension device, and belongs to the technical field of metal continuous steel casting. The roller way chain tension device comprises a sliding frame, a slider is arranged on a vertical sliding rail of the sliding frame, a groove is arranged on the slider, a sliding shaft is arranged in the groove, a tension wheel is movably sleeved on the sliding shaft, a hole is longitudinally arranged on the slider, a lead screw is arranged in the hole and penetrates through a steel plate arranged on a roller way beam, and a lead screw nut is arranged on the lead screw. The tension device is fixed onto the roller way beam through bolts, basic fixing needed by a traditional tension device is omitted, occupied space is saved, and the roller way chain tension device is simple in structure, convenient to adjust and suitable for tensioning roller ways in continuous casting devices.
Description
Technical field
The utility model belongs to metal continuous casting steel machine technical field, relates to a kind of roller-way chain stretching device.
Background technology
When roller-way adopts chain-driving and two centre of sprocket distance greatly, running quickly into side chain bar in tension of transmission side sprocket wheel, and the side chain bar that rushes out of of driving chain wheel is in relaxed state is when heavily loaded frequent starting, braking and rotating, chain may get loose, especially behind the chain wear, the possibility that gets loose is bigger, thereby causes transmission failure, influence the normal operation of equipment, and chain is in the situation of no tightening device, and Installation and Debugging are difficulty relatively, and dismounting neither be very convenient during overhaul of the equipments.Traditional tensioning device structure more complicated, it is bigger to take up room, and adjusts inconvenience, is not suitable for using on the continuous casting roller-way.
Summary of the invention
The purpose of this utility model is at above-mentioned defective, provides a kind of when roller-way adopts sprocket wheel chain central driving, can guarantee the stationarity of chain in transmission process, the roller-way chain stretching device of avoiding chain to get loose.
The technical solution adopted in the utility model is: it comprises balladeur train, the upright slide rail of balladeur train is provided with slide block, have groove on the slide block, be provided with slide shaft in the groove, activity is with tension wheel on the slide shaft, vertically has the hole on the slide block, is provided with screw mandrel in the hole, screw mandrel passes the steel plate that is located on the roller-way beam, and screw mandrel is provided with the feed screw nut.
Further, be provided with bearing and axle sleeve between described slide shaft and the tension wheel, axle sleeve is connected with slide shaft.
The utility model adopts tightening device by being bolted on the roller-way beam, has avoided the required basic fixed of traditional tensioning, saved to take up room, and tensioning relatively simple for structure, that regulate also easily, be fit to roller-way in the continuous casting installation for casting.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the front view of tightening device in roller-way is installed;
Fig. 3 is the birds-eye view of tightening device in roller-way is installed.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments, is convenient to be well understood to the utility model, but they do not constitute qualification to the utility model.
As shown in Figure 1, the utility model tightening device 1 comprises balladeur train 8, and the upright slide rail of balladeur train 8 is provided with slide block 13, have groove on the slide block 13, be provided with slide shaft 7 in the groove, activity is with tension wheel 4 on the slide shaft 7, is provided with bearing 2 and axle sleeve 3 between slide shaft 7 and the tension wheel 4, axle sleeve 3 is connected with slide shaft 7, tension wheel 4 is fixing by shaft end ring and slide shaft 7, vertically has the hole on the slide block 13, is provided with screw mandrel in the hole, screw mandrel passes the steel plate 6 that is located on the roller-way beam 10, and screw mandrel is provided with feed screw nut 5.
As shown in Figure 1, balladeur train 8 in the tightening device 1 is fixing by bolt and roller-way beam 10, slide shaft 7 can slide up and down for 8 li at balladeur train, in the operational process, tension wheel 4 is adjusted to correct position, be welded on steel plate 6 on the roller-way beam 10 this moment, slide bar on the slide shaft 7 is connected with steel plate 6 by feed screw nut 5 and plays positioning action, and the route problem of tension wheel 4 can be regulated by the length of balladeur train 8, in the roller-way operational process, by turning feed screw nut 5, regulate the position of tension wheel 4 by screw mandrel, drive slide shaft 7 and on balladeur train 8, slide, thereby regulate tension wheel 4 and live roll assembling 9, transmission shaft assembles the distance of 11 middle sprockets, reaches slack-free purpose.
As Fig. 2, shown in Figure 3, with tightening device 1 by being bolted on the roller-way beam 10, tightening device 1 is arranged in the middle of live roll assembling 9 and the transmission shaft assembling 11, adjusting by tightening device 1, avoided bad and vibration chain 12 because of the excessive engagement that causes of chain 12 severes, increased the engagement wrapping angle of chain 12 and sprocket wheel simultaneously, the driving efficiency height.
As Fig. 2, shown in Figure 3, tightening device 1 is fixed on the roller-way beam 10, has avoided traditional tightening device to take up space greatly, complex structure and other problems, and tightening device 1 range-adjustable is big, is fit to very much the roller-way tensioning.
