Examples

Referring to fig. 1-7, the present invention provides a drum mechanism for a crane, which comprises: the utility model provides a reel mechanism for hoist, including barrel 1, it has transmission shaft 11 to run through the welding in barrel 1, positioning flange 12 is installed at the both ends of barrel 1, install positioning mechanism 2 between the positioning flange 12, positioning mechanism 2's inboard is connected with fastening device 3, fastening device 3 is including spout 31, location clamping piece 32, couple 33, go-between 34, connecting rod 35 and extension spring 36, spout 31 has been seted up on barrel 1, spout 31 sliding connection has location clamping piece 32, location clamping piece 32 is connected with couple 33 through seting up the through-hole in barrel 1's one end, the other end welding of couple 33 has go-between 34, the other end threaded connection of go-between 34 has connecting rod 35, the welding has extension spring 36 between the connecting rod 35, by extension spring 36 through pulling connecting rod 35, go-between 34 and couple 33, give positioning mechanism 2 and apply a pulling force constantly, when the steel cable leads to the internal diameter reduction because long-term wearing and tearing lead to the pulling force that positioning mechanism 3 applyed for positioning mechanism 2, make the steel cable still can closely arrange on barrel 1, the protection has been strengthened to the steel cable, service life has been improved, the risk of card rope has been reduced.

Positioning mechanism 2 installs positioning disk 21 between flange 12 including positioning disk 21 and grooving 22 on the outer terminal surface of barrel 1, has seted up grooving 22 on the terminal surface of positioning disk 21 keeping away from flange 12 one side, and grooving 22 of positioning disk 21 inboard has played fine positioning action when the steel cable is arranged for each layer of steel cable can both be in order to block in between the gap of next layer of steel cable.

The even lathe work in one side that positioning disk 21 is close to positioning flange 12 has a plurality of clamping groove 211, positioning clamping piece 32 passes through the bolt in the one end in the barrel 1 outside and is connected with clamping groove 211, positioning clamping piece 32's the other end is fixed on positioning disk 21, the other end card is in barrel 1's spout 31, produce the pulling force when fastening mechanism 3, positioning clamping piece 32 can drive positioning disk 21 when tightening up in spout 31 and press from both sides tightly to the centre, positioning disk 21 all tightens up the minimum with the clearance of each layer of steel cable this moment, make the range of steel cable more orderly, inseparable.

A plurality of threaded holes are formed in the positioning flange 12 in a penetrating mode, the barrel body 1 is fixedly connected with the positioning flange 12 through bolts inserted into the threaded holes, and the positioning flange 12 mainly functions to prevent the fastening mechanism 3 from falling off from the barrel body 1 when the fastening mechanism 3 does not work at the positioning mechanism 2.

The inboard welding at spout 31 both ends has stopper 311, and when the steel cable of the first layer was not arranged when full on barrel 1, stopper 311 can prevent that positioning mechanism 2 is because excessively tighten up, leads to the steel cable to retrieve smoothly.

The extension spring 36 is made of chrome vanadium steel, which is somewhat more expensive than other materials, but has better toughness and strength, and a higher elastic limit, and is therefore more suitable for use in a reel mechanism.

The utility model discloses a theory of operation as follows:

when the winding drum mechanism for the crane works, when an object needs to be lowered, the hooks 33 and the positioning clamping pieces 32 in all the fastening mechanisms 3 are firstly loosened, the motor drives the barrel body 1 to rotate, the steel ropes on the barrel body 1 are gradually lowered, then the object is lowered to a specified height, when the object needs to be lifted, the hooks 33 in all the fastening mechanisms 3 are hung on the positioning clamping pieces 32, the positioning clamping pieces 32 drive the positioning disc 21 to tighten and extrude the steel ropes inwards under the tensile force action of the fastening mechanisms 3, so that the steel ropes are tightly arranged on the surface of the barrel body 1, and meanwhile, in the steel rope recovery process, the rope grooves 22 have a good limiting effect on the steel ropes, make the steel cable of every layer can both block smoothly on the gap between the next layer steel cable, through increasing fastening device 3 and carrying out a series of improvements to positioning mechanism 2, the problem of the steel cable can't closely arrange because long-term work leads to the diameter to reduce, the reel is arranging comparatively loosely tightening up in-process next layer steel cable, lead to the problem that the easy card of last layer steel cable goes into the next layer gap, make this a reel mechanism for hoist receive the rope performance in the use obtain great improvement, simultaneously under positioning disk 21 and grooving 22's effect, the recovery location of steel cable is more accurate, greatly reduced the risk of card rope, and the production efficiency is improved, and the use cost of hoist is saved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
