Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment, the utility model is further described.
Embodiment one, see Fig. 1, a kind of fixed type driving, the lifting motor 5 comprising suspension bracket 1, suspension hook 2, wire spool 3, hoist cable 4 and drive wire spool to rotate.
Suspension bracket 1 comprises vertical rod 11 and cross bar 12.Vertical rod 11 is circular tube structure.Vertical rod 11 comprises upper boom 111 and lower beam 112.The lower end of lower beam 112 is connected with adapter plate 6.If adapter plate 6 is provided with the bolt hole 61 of through adapter plate.Some bosses 7 are provided with between adapter plate 6 and hypomere 112.Boss 7 is along the distribution of vertical rod 11 circumference.The upper end of boss 7 is provided with chamfering 71 away from the side of vertical rod.The upper end of lower beam 112 is sheathed and be threaded in the lower end of upper boom 111.The upper end of upper boom 111 and cross bar 12 are that right-hand member links together.Cross bar 12 is circular tube structure.Diagonal ligament 9 is provided with in the middle of cross bar 12 and upper boom 111.
Suspension hook 2 is connected to the lower end of hoist cable 4.The upper end Co-wound coil dish 3 of hoist cable 4 links together.Wire spool 3 is linked together with lifting motor 5 by retarder 53.Lifting motor 5 is fixed on the left end of cross bar 12.Lifting motor 5 comprises motor casing 52 and motor shaft 51(see Fig. 2).Motor shaft drives wire spool 3 to rotate by retarder 53.Lifting motor 5 is also linked together with master cock 59 by power lead 54.Master cock 59 is for controlling lifting motor 5 rotating.
During use, realize the utility model to fix on the ground through the bolt hole 61 on adapter plate 6 by holding-down bolt.Then the object be lifted is hung on suspension hook 2, control lifting motor 5 by master cock 59 to work, during lifting motor 5, wire spool 3 rotates, and realizes the folding and unfolding of hoist cable 4 when wire spool 3 rotates, realize the lifting of suspension hook 2 during hoist cable 4 folding and unfolding, thus realize the lifting of object.
Embodiment two, the difference with embodiment one is:
See Fig. 2, motor shaft 51 is supported in motor casing 52 by two bearings 55.Fueling cavity 56 is formed between motor casing 52 and two bearings 55.The first gear 58 and the second gear 57 is provided with in fueling cavity 56.First gear 58 and the second gear 57 mesh together.First gear 58 links together with motor shaft 51.Second gear 57 is rotatably connected with motor casing 52 by minor axis 571.
See Fig. 3, in the first gear 58, be provided with oil-filling mechanism 8.The number of oil-filling mechanism 8 is equal with the number of teeth of the first gear 58.
See Fig. 4, oil-filling mechanism 8 comprises oil outlet 81, gas supplementing opening 82, sealing head 83, first spring 84, cylinder body 85 and piston 86.The oil outlet 81 of same oil-filling mechanism and gas supplementing opening 82 are arranged on the tooth top 581 of the same tooth of the first gear 58, the tooth top of same tooth only arranges oil outlet and the gas supplementing opening of an oil-filling mechanism, and namely in the present embodiment, the tooth of oil-filling mechanism and the first gear 58 is arranged correspondingly.Sealing head 83 and the first spring 84 are arranged in oil outlet 81, stretch out tooth top 581 at the effect lower seal head 83 of the first spring 84 and seal up oil outlet.The distance L1 that sealing head stretches out the tooth top of the first gear is greater than tooth top gap L2(between the first gear and the second gear see Fig. 5).Cylinder body 85 is formed in the first gear 58 in the mode of integrative-structure, is the chamber in the first gear 58.Piston 86 slipper seal is connected to cylinder body 85.Cylinder body 85 is divided into air cavity 851 and oil pocket 852 by piston 86.Piston 86 is provided with the check valve 861 opened towards air cavity 851.Piston 86 is linked together with sealing head 83 by connecting rod 862.Connecting rod 862 links together with slipper seal between the first gear 58, and oil outlet 81 is disconnected with air cavity 851.Oil outlet 81 is connected with oil pocket 852 by oil duct 87.Gas supplementing opening 82 is connected with air cavity 851 by air flue 88.Oil duct 87 and air flue 88 are all be formed in the first gear 58 in the mode of integrative-structure, are the hole in the first gear 58.
The process of the lubrication of the bearing in the present invention is:
See Fig. 3, in the process that the first gear 58 rotates, shrink in bottom surface crush seal 83 to first gear 58 of the teeth groove of the second gear 57, sealing head 83 shrinks and oil outlet 81 is opened and makes the first spring 84 energy storage.
See Fig. 5, also moved towards oil pocket 852 by connecting rod 862 driven plunger 86 when sealing head 83 shrinks, the pressure increase in oil pocket 852 is closed by check valve 861 and lubricating oil in oil pocket 852 flows to oil outlet 81 through oil duct 87 and flows out from oil outlet 81 and realize the lubrication to bearing 55.
When the second gear loses the squeezing action to sealing head 83, move outside the effect lower seal head 83 of the first spring 84 and oil outlet 81 is sealed up, moved towards air cavity 851 by connecting rod 862 driven plunger 86 when sealing head 83 stretches out, pressure drop in oil pocket 852 and pressure increase in air cavity 851, check valve 861 is opened, oil unnecessary in air and fueling cavity 56 is through gas supplementing opening 82, air flue 88 and check valve 861 and flow to oil pocket 852, the air pressure that pressure in oil pocket 852 can be maintained in same gear exterior is equal, so that lubricating oil can squeeze out by piston 86 when oil pocket 852 moves next time.
