Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The first embodiment is as follows:
as shown in figure 1, the utility model relates to a cantilever crane for a steel rolling roller way, which comprises a bracket 1 and a crane 3. The support 1 comprises a base, and four uniformly distributed rollers 2 are mounted at the lower end of the base and can move. The two sides of the upper end of the base are provided with symmetrical and vertically arranged branch pipes 11. As shown in fig. 3, reinforcing ribs are further provided on both sides of the branch pipe 11 to improve the structural strength thereof.
The lifting frame 3 comprises a cross beam 32, and the hoist crane 4 is arranged at one end of the cross beam 32 and used for lifting a roller way. Two insertion rods 31 are arranged at the lower end of the other end of the cross beam 32. The insertion rod 31 is inserted into the branch pipe 11 for lifting and guiding. And the inserting rod 31 and the branch pipe 11 are both provided with two connecting rods for improving the lifting stability of the lifting frame 3.
As shown in fig. 2, a feed screw nut 6 is fixedly mounted at the lower end of the insertion rod 31, and a feed screw 5 in threaded connection with the feed screw nut 6 is inserted into the insertion rod 31.
The base is internally provided with a horizontal synchronous shaft 7, and two ends of the synchronous shaft are movably connected with the base through bearings. First bevel gears 8 are arranged at two ends of the synchronizing shaft 7, a second bevel gear 9 is arranged at the lower end of the screw rod 5, and the first bevel gear 8 is meshed with the second bevel gear 9. The screw rod 5 can be driven to synchronously rotate by driving the synchronous shaft 7, so that the inserting rod 31 is driven to synchronously lift.
Both ends of synchronizing shaft 7 all are provided with hand wheel 14, select one of them hand wheel 14 according to the operating mode can drive synchronizing shaft 7 rotatory.
When the roller way needs to be replaced, the bracket 1 is pushed to move the utility model to one side of the roller way; then, the hand wheel 14 is driven to adjust the height of the hoist crane 4; hoisting the roller way by using a hoist crane 4; finally, the bracket 1 is pushed, and the roller way can be lifted out; and the same operation is carried out to hoist the roller way which normally runs to the working position, so that the roller way is replaced, and the smooth production is ensured. The utility model discloses it is convenient not only to remove, replaces traditional overhead traveling crane moreover to practiced thrift repair time, improved production efficiency. Moreover, the height of the hoist crane 4 is adjustable, the hoist crane is suitable for roller beds with different heights, and the practicability is wider.
Example two:
compared with the first embodiment, the differences are as follows: the two ends of the synchronizing shaft 7 are both provided with lower belt pulleys 12, and upper belt pulleys 13 arranged on the bracket 1 are arranged above the lower belt pulleys 12; the lower belt pulley 12 and the upper belt pulley 13 are linked through a belt; the hand wheel 14 is mounted on the outside of the upper pulley 13. By the arrangement, the worker can operate the hand wheel 14 when standing upright, so that the lifting frame 3 is driven to lift, and the operation is very convenient.
