The shaft end of the brake gear shaft 52 is connected with the water-cooled brake 51, and the gear end of the brake gear shaft 52 penetrates through the frame 10 to be meshed with the large gear ring 20 a.

Fig. 5 is a schematic structural diagram of a water-cooled brake pump station according to an embodiment of the present invention, and as shown in fig. 5, the braking mechanism 50 further includes a water-cooled brake pump station 53, and the water-cooled brake pump station 53 includes an inlet and an outlet 53A. The water inlet/outlet port 53A of the water-cooled brake pump station 53 communicates with the water inlet/outlet port 51A (see fig. 4) of the water-cooled brake 51.
The water-cooled brake pump station 53 is configured to supply an aqueous medium of a set pressure to the water inlet/outlet 51A of the water-cooled brake 51 when the hook is unloaded, so that the first inner friction plate 51A and the first outer friction plate 51b are frictionally slid by water pressure.
For example, as shown in fig. 4, when the hook is lowered without load, the water-cooled brake pump station 53 provides an aqueous medium with a set pressure to the water inlet/outlet 51A of the water-cooled brake 51, and the aqueous medium enters the cavity S1 to push the first outer friction plate mounting plate 51c, so that the distance between the plurality of first outer friction plate mounting plates 51c decreases, the elastic sealing element 51d is compressed, and the distance between the first inner friction plate 51A and the first outer friction plate 51b in the water-cooled brake 51 gradually decreases until the first inner friction plate 51A and the first outer friction plate 51b are in close contact, and the water-cooled brake 51 is closed. At this time, when one of the first inner friction plate 51a or the first outer friction plate 51b rotates, the other one is driven to rotate together.

When the water-cooled brake 51 is switched from the off state to the on state or from the on state to the off state, the water-cooled brake 51 is in a sliding friction state, that is, although a certain gap exists between the first inner friction plate 51a and the first outer friction plate 51b, sliding friction occurs between the first inner friction plate 51a and the first outer friction plate 51b, and friction force is generated. The magnitude of the frictional force can be controlled by controlling the flow rate of the aqueous medium supplied from the water-cooled brake pump station 53 to the water inlet/outlet 51A of the water-cooled brake 51 and the pressure in the cavity S1.
The water-cooled brake 51 is illustratively of a normally closed configuration.
Further, the water-cooled brake 51 further comprises a water circulation system (not shown in the figure), and the water circulation system is configured to drive the water medium to continuously circulate in and out of the water-cooled brake 51 when the hook is unloaded, so as to reduce heat generated by sliding friction between the first inner friction plate 51a and the first outer friction plate 51b, and realize working heat balance of the water-cooled brake 51.

The hydraulic clutch 41 includes second inner friction plates 41a, second outer friction plates 41b, and a case 41c, the second inner friction plates 41a and the second outer friction plates 41b are alternately arranged at intervals in the axial direction of the case 41c, and the second outer friction plates 41b are fixed to the case 41 c. The output shaft 30a of the power mechanism 30 is coaxially disposed in the housing 41c, and the second inner disk 41a is fixed to the output shaft 30a of the power mechanism 30.
The hydraulic clutch pump 43 is configured to recover hydraulic oil in the hydraulic clutch 41 and separate the second inner friction plate 41a from the second outer friction plate 41b when the hook is lowered without load.
For example, as shown in fig. 6, when the hook is lowered without load, the hydraulic clutch pump 43 supplies hydraulic oil with a set pressure to the oil inlet/outlet 41A of the hydraulic clutch 41, the volume of the cavity S2 is gradually increased after the hydraulic oil enters the cavity S2, the spring 41d is gradually extended, the second outer friction plates 41b are pushed, the distance between the second outer friction plates 41b is reduced, and the hydraulic clutch is closed until the second inner friction plates 41A and the second outer friction plates 41b are in close contact. At this time, one of the second inner friction plate 41a and the second outer friction plate 41b rotates while the other rotates.
When the hydraulic clutch 41 is opened, the aqueous medium in the cavity S2 flows back to the hydraulic clutch pump 43 through the oil inlet/outlet 41A, the spring 41d gradually contracts, the distance between the second outer friction plates 41b gradually increases, and the distance between the second inner friction plate 41A and the second outer friction plate 41b gradually increases until a certain gap exists between the second inner friction plate 41A and the second outer friction plate 41b, and at this time, when one of the second inner friction plate 41A or the second outer friction plate 41b rotates, the other does not rotate.
Further, as shown in fig. 6, the output gear shaft 42 is drivingly connected to the hydraulic clutch 41 through a connecting member.
Illustratively, the connecting piece may include a cylinder 44, a flange plate 45 and a bolt 46, the cylinder 44 is sleeved outside the shaft end of the output gear shaft 42, the shaft end of the output gear shaft 42 is in key connection with the cylinder 44, the flange plate 45 is arranged at one end of the cylinder 44, and the flange plate 45 is fixedly connected with the housing 41c of the hydraulic clutch 41 through the bolt 46.
When the output gear shaft 42 rotates, the housing 41c of the hydraulic clutch 41 and the second outer friction plates 41b both rotate.
Illustratively, the hydraulic clutch 41 is of a normally closed configuration.
The working process of the winch provided by the embodiment of the invention is briefly described as follows:
1) when the winch realizes the lifting action of the lifting hook goods:
the hydraulic oil in the hydraulic clutch 41 is returned to the hydraulic clutch pump station 43, and the hydraulic clutch 41 is closed. The clutch mechanism 40 is used to transmit the driving force provided by the power mechanism 30 to the output gear shaft 42, and the output gear shaft 42 rotates the large ring gear 20 a.
The large gear ring 20a drives the braking gear shaft 52 to rotate, at this time, water in the water-cooled brake 51 flows back to the water-cooled brake pump station 53, and the water-cooled brake 51 is started. The brake mechanism 50 does not brake the large ring gear.
2) When the lifting hook performs the idle-load lowering action:
the hydraulic clutch pump station 43 feeds oil into the hydraulic clutch 41, and the hydraulic clutch 41 is opened. The clutch mechanism 40 breaks the transmission connection between the power mechanism and the large gear ring, and prevents the influence of the rotation of the clutch mechanism 40 on the power mechanism 30.
The large gear ring 20a drives the braking gear shaft 52 to rotate, at this time, the water-cooled brake 51 can be in a sliding friction state by adjusting the flow rate and pressure of the aqueous medium supplied to the water-cooled brake 51 by the water-cooled brake pump station 53, and the first inner friction plate 51a and the first outer friction plate 51b slide and rub under the action of water pressure to generate friction force.
Illustratively, as shown in fig. 1, the friction force is converted into a resistance force which hinders the rotation of the braking gear shaft 52, so as to decelerate and brake the large gear ring 20a, so that the hook on the winding drum is controlled to be lowered under the braking force provided by the braking mechanism 50, rather than performing a free-fall movement, and the hook is quickly lowered while ensuring the safety of lowering the hook.
By adopting the winch provided by the invention, the ratio of the lowering speed of the lifting hook to the lifting speed can reach 10 times, and the speed regulation range is far larger than the speed regulation range of 2.5 times of the existing frequency modulation motor.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
