The described locking member that surges comprises with top roll and is the fixing housing of equalizer bar and is located at hydraulic motor, gear driving member, inner thread sleeve, spacing collar and pull bar on the housing that hydraulic motor output shaft links to each other with inner thread sleeve by gear driving member; Spacing collar is sheathed on the pull bar, and spacing collar is provided with external screw thread and is located at and carries out threaded engagement in the inner thread sleeve; Pull bar upper end is provided with block, the lower end with lead a parts and fix.
Described gear driving member comprises little, the gear wheel that is meshed, and pinion links to each other with hydraulic motor output shaft, and gear wheel radially is fixed on the inner thread sleeve.
The described locking member that surges also comprises spacing controlling organization, spacing controlling organization is located on the housing, comprise pulley, pull rope, weight and near switch, pulley is located at the housing upper end, pull rope one end links to each other with spacing collar, the other end is walked around pulley and is connected with weight, and several are located at housing one side successively near switch.
In technique scheme, the guide device of sheet rolling mill of the present utility model comprises leads a parts and two hoist cylinders, also comprises the locking member that surges, and is located between two oil cylinders, also to be fixed on top roll be on the equalizer bar in the upper end, the lower end also with lead a parts and link to each other.The locking member pull bar that surges hang lead a parts and with the hoist cylinder synchronization lifting, and control spacing collar by hydraulic motor and carry out corresponding lifting, and form longitudinal spacing with the block on pull bar top, thereby can prevent the generation of guide and guard parts falling accident, reduce repair time and economic loss.

Fig. 2 is the structural representation of guide device of the present utility model;
Fig. 3 is the cutaway view of the locking member that surges of the present utility model.
The specific embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
See also shown in Figure 2, the guide device 20 of sheet rolling mill of the present utility model is basic identical with prior art, equally also comprise and lead a parts 21 and two hoist cylinders 22, it is on the equalizer bar 1 that oil cylinder 22 upper ends are fixed on top roll, the lower end piston rod with lead a parts 21 and link to each other.Different is, this guide device 20 also comprises the locking member 23 that surges, and is located between two oil cylinders 22, and it is on the equalizer bar 1 that the upper end also is fixed on top roll, the lower end also with lead a parts 21 and link to each other.Please in conjunction with shown in Figure 3, this locking member 23 that surges comprise with top roll be the fixing housing 231 of equalizer bar 1, and be located at hydraulic motor 232, gear driving member, inner thread sleeve 234, spacing collar 235 and pull bar 236 on the housing 231, the output shaft of hydraulic motor 232 links to each other with inner thread sleeve 234 by gear driving member; Spacing collar 235 is sheathed on the pull bar 236, and spacing collar 235 is provided with external screw thread and is located at and carries out threaded engagement in the inner thread sleeve 234; Pull bar 236 upper ends are provided with block 237, the lower end with lead a parts 21 and fix.And gear driving member specifically comprises little, the gear wheel that is meshed, and pinion 233a links to each other with the output shaft of hydraulic motor 232, and gear wheel 233b radially is fixed on the inner thread sleeve 234.
In addition, this locking member 23 that surges also comprises a spacing controlling organization, this spacing controlling organization is located on the housing 231, comprise pulley 241, pull rope 238, weight 239 and near switch 240, pulley 241 is located at housing 231 upper ends, and pull rope 238 1 ends link to each other with spacing collar 235, and the other end is walked around pulley 237 and is connected with weight 239, several are located at housing 231 1 sides successively near switch 240, are set to spacing positions such as upper and lower limit and warning respectively.
The operation principle of the guide device 20 of sheet rolling mill of the present utility model is as follows:
When roll change, drive gear wheel 233b by hydraulic motor 232 driving pinion 233a and rotate, be displaced downwardly to the bottom thereby make inner thread sleeve 234 rotations and drive spacing collar 235, at this moment, lead a parts 21 by hoist cylinder 22 drives and descend, and pull bar 236 also can descend with leading a parts 21; When the dress roller, drive guide and guard parts 21 by hoist cylinder 22 and rise to the precalculated position, then, same control hydraulic motor 232 drives inner thread sleeve 234 counter-rotatings, thereby drive spacing collar 235 moves to pull bar 236 from the bottom top, and offset, thereby block pull bar 236 with block 237, make pull bar 236 hang the guide and guard parts all the time, play the purpose that prevents that the guide and guard parts from falling suddenly.In this process, weight 239 carries out oppositely moving with the lifting of spacing collar 235 by pull rope 238, and triggers accordingly near switch 240, and by sending signal near switch 240, in order to the driving of automatic control hydraulic motor 232.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
