Description

Technical Field

[0001] The utility model relates to the technical field of wire rope winches, and particularly relates to a wire rope winch and a lifting wire rope assembly. Background Art

[0002] A wire rope winch is a common and practical mechanical device, mainly used for towing, lifting and dragging heavy objects. Wire rope winches are widely used in many fields. For example, in construction projects, they are used to lift and transport building materials; in vehicle rescue, they help trapped vehicles get out of trouble; in the ship field, they assist ships in taking in and paying out anchor chains, etc.

[0003] The existing wire rope winches mainly consist of parts such as a drum, a driving device, a braking device, a frame, etc. Among them, the output shaft of the driving device is directly connected to the drum to provide power for it. When towing a heavier object, the higher the requirement for the power source. If in some special application scenarios during application, when electrical energy or hydraulic energy cannot be used as the power source, and thus only a manual handwheel is used as the power source, it will be very laborious and not conducive to improving productivity. Content of the Utility Model

[0004] In order to solve the above technical problems, the purpose of the utility model is to provide a wire rope winch and a lifting wire rope assembly.

A pulley block is fixedly installed on the top of the support bracket. A lifting object material frame is slidably installed on the side of the support bracket. A connecting plate is installed on the support rod of the support bracket. It is characterized in that a worm and gear reducer is fixedly installed on the top of the mounting base through bolts. The top of the worm and gear reducer is fixedly installed with the connecting plate through bolts. A power source is fixedly installed on the input shaft at one end of the worm of the worm and gear reducer. A four-stage stepped shaft is installed on the worm of the worm and gear reducer. The four-stage stepped shaft is successively arranged from thin to thick as the first-stage stepped shaft, the second-stage stepped shaft, the third-stage stepped shaft and the fourth-stage stepped shaft. The outer surface of the first-stage stepped shaft is sleeved on the worm of the worm and gear reducer. The second-stage stepped shaft is used to limit the insertion depth of the worm of the worm and gear reducer. A wire rope is wound on the third-stage stepped shaft. The fourth-stage stepped shaft is a thin shaft used to limit the position of the wound wire rope. One end of the wire rope passes through the pulley block and is connected with a fish-eye screw. The fish-eye screw is fixedly installed on the connecting rod at the bottom of the lifting object material frame through bolts.

[0007] As a further solution of the utility model: the screw rod of the fish-eye screw penetrates through the connecting rod at the bottom of the lifting object frame, and two nuts are respectively threadedly installed at the upper and lower ends of the screw rod of the fish-eye screw to fix the connecting rod at the bottom of the lifting object frame.

[0008] As a further solution of the utility model: a keyway is provided on the cylindrical surface of the first-stage stepped shaft. The outer surface of the first-stage stepped shaft is sleeved into a worm and worm gear reducer and fixed by installing a flat key in the keyway. A threaded hole one is provided at the end of the first-stage stepped shaft, and a gasket and a bolt are assembled on the threaded hole one to axially fix the four-stage stepped shaft in the worm and worm gear reducer.

[0009] As a further solution of the utility model: a plurality of adjacent planes are milled on the cylindrical surface of the third-stage stepped shaft near one end of the second-stage stepped shaft. A threaded hole two is provided on each of the plurality of planes, and a wire rope pressing plate can be detachably installed on the threaded hole two through a bolt, and the wire rope is fixed on the third-stage stepped shaft through the wire rope pressing plate.

[0010] As a further solution of the utility model: a notch is provided at the bottom of the wire rope pressing plate. One end of the wire rope is bent into a U shape, and one end of the U shape is stuck into the corresponding notch of the wire rope pressing plate, and then the wire rope pressing plate is pressed against one end of the wire rope through a screw in the middle and fixed to the plane.

[0011] As a further solution of the utility model: a spiral groove is also milled on the third-stage stepped shaft, and the depth of the spiral groove is the same as the radius of the wire rope.

[0012] As a further solution of the utility model: the pitch of the spiral groove is 1.2 times the diameter of the wire rope.

[0013] As a further solution of the utility model: a track groove is fixedly installed on one side of the support bracket, and a track is installed on the side of the lifting object frame opposite to the support bracket, and the track is slidably installed in the track groove.

A connecting plate 2 is installed on the support rod of the support bracket 11. A worm and gear reducer 3 is fixedly installed on the top of the mounting base 1 by bolts. The top of the worm and gear reducer 3 is fixedly installed with the connecting plate 2 by bolts. A power source 31 is fixedly installed on the input shaft at one end of the worm of the worm and gear reducer 3. The power source 31 can be set as a right-angle reducer or a horn-shaped handwheel. A four-stage stepped shaft 4 is installed on the turbine of the worm and gear reducer 3. The four-stage stepped shaft 4 is sequentially arranged from thin to thick as the first-stage stepped shaft 41, the second-stage stepped shaft 42, the third-stage stepped shaft 43, and the fourth-stage stepped shaft 44. The outer surface of the first-stage stepped shaft 41 is sleeved on the turbine of the worm and gear reducer 3. A keyway 412 is opened on the cylindrical surface of the first-stage stepped shaft 41. The outer surface of the first-stage stepped shaft 41 is sleeved with the worm and gear reducer 3 and is fixed by installing a flat key in the keyway 412. A threaded hole 414 is opened at the end of the first-stage stepped shaft 41. A gasket and a bolt are assembled on the threaded hole 414 to fix the axial direction of the four-stage stepped shaft 4 and the worm and gear reducer 3.

[0030] The second-stage stepped shaft 42 is used to limit the insertion depth of the four-stage stepped shaft 4 into the worm and gear reducer 3. A wire rope 5 is wound around the third-stage stepped shaft 43. A plurality of adjacent planes 431 are milled on the cylindrical surface of the third-stage stepped shaft 43 near one end of the second-stage stepped shaft 42. A threaded hole 432 is opened on each of the plurality of planes 431. A wire rope pressing plate 433 is detachably installed on the threaded hole 432 by a bolt. The wire rope 5 is fixed on the third-stage stepped shaft 43 by the wire rope pressing plate 433. A notch 434 is opened at the bottom of the wire rope pressing plate 433.
