The mill connecting shaft jumping can cause damage to the mill, the speed reducer and the motor in different degrees, and the online operation period of the equipment is short.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a rolling mill bracket to solve the problems in the prior art.
The utility model is realized by the following technical scheme: a mill carriage characterized by: comprises a base, wherein one side of the base is provided with an ear part connected with a rolling mill; two supporting arms are oppositely arranged at the upper part of the base, and two sliding grooves are arranged on each supporting arm; trunnion slide blocks are arranged at two ends of a roller sleeve of a rolling mill conveying roller and matched with the sliding grooves; wear-resisting blocks are respectively arranged above and below the inside of the sliding chute; the upper part of the supporting arm is provided with a chain wheel, the adjusting chain is matched with the chain wheel, one end of the adjusting chain is fixed on the trunnion slide block of the upper roller sleeve, and the other end of the adjusting chain is connected with the adjusting device on the trunnion slide block of the lower roller sleeve.
Further: the adjusting device comprises an adjusting screw rod inserted on the trunnion slide block, an adjusting cap is in threaded connection below the adjusting screw rod, an adjusting spring is further arranged between the adjusting cap and the trunnion slide block, and the adjusting spring is sleeved on the adjusting screw rod.
Further: a rolling mill carriage according to the above, characterized in that: the spout is enclosed by the recess that sets up in the support arm side and the baffle of spiro union in the support arm outside and closes and form.
The utility model has the beneficial effects that: the structure of the utility model optimizes the structural form of the original bracket, the position of the bracket which is most easily worn is additionally provided with the wear-resistant block, and the wear-resistant block can be replaced, thereby solving the problem of poor overall strength caused by the fact that the original bracket can not be subjected to heat treatment. The wear-resistant blocks are connected by bolts, so that the wear-resistant blocks are convenient and quick to replace; the material of the wear-resistant block can be freely selected according to actual requirements, and is not limited by the fact that the material with good wear resistance cannot be selected due to poor welding performance; the wear blocks may be heat treated separately. In addition, the structure of the utility model solves the problem of fast abrasion of the bracket, prolongs the service life and saves the cost; meanwhile, frequent maintenance can be avoided, the installation and the disassembly are convenient and quick, and the labor intensity of workers is reduced; because of good shock resistance, the service life of the speed reducer and the motor is also prolonged.

The sequence numbers in the figures illustrate: the device comprises a base 1, an ear part 2, a support arm 3, a sliding chute 4, a roller sleeve 5, a trunnion slide block 6, a wear-resistant block 7, a chain wheel 8, an adjusting chain 9, an adjusting device 10, an adjusting screw 101, an adjusting cap 102, an adjusting spring 103, a baffle 11 and a reinforcing rib plate 12.
Detailed Description
As shown in figures 1-3, the rolling mill bracket of the utility model is used for supporting an upper group of conveying shafts and a lower group of conveying shafts of a rolling mill, and comprises a base 1, wherein one side of the base is provided with an ear part 2 connected with the rolling mill, the ear part is provided with a shaft hole matched with a fixed shaft, and the base is fixed on a frame of the rolling mill through the fixed shaft; two supporting arms 3 are oppositely arranged on the upper part of the base, and each supporting arm is provided with two sliding chutes 4 which are distributed up and down; the two ends of a conveying roller of the rolling mill are provided with roller sleeves, the two ends of the conveying roller are connected with the roller sleeves through bearings, the two ends of the roller sleeve 5 are provided with rectangular trunnion slide blocks 6, and the trunnion slide blocks are matched with the sliding grooves and can slide up and down in the sliding grooves; wear-resisting blocks 7 are respectively arranged above and below the inside of the sliding groove, and the wear-resisting blocks are fixed in the sliding groove through bolts, so that the impact of the trunnion sliding block on the sliding groove can be effectively reduced; the upper part of the supporting arm is provided with a chain wheel 8, an adjusting chain 9 is matched with the chain wheel, one end of the adjusting chain is fixed on the trunnion slide block of the upper roller sleeve, and the other end of the adjusting chain is connected with an adjusting device 10 on the trunnion slide block of the lower roller sleeve.
Preferably: the adjusting device 10 comprises an adjusting screw 101 inserted on the trunnion slide block and capable of moving relative to the trunnion slide block, an adjusting cap 102 is connected below the adjusting screw in a threaded manner, and an adjusting spring 103 is further arranged between the adjusting cap and the trunnion slide block and sleeved on the adjusting screw.
