Description

A winch fixing frame

Technical Field

The utility model relates to the technical field of winches, in particular to a winch fixing frame.

Background Art

A winch is a light and small lifting equipment that uses a drum to wrap a wire rope or chain to lift or pull heavy objects. It is also called a winch. The winch can lift vertically, pull heavy objects horizontally or at an angle. It can be used alone or as a component of machinery such as lifting, road construction and mine hoisting. It is widely used due to its simple operation, large rope winding capacity and easy relocation. It is mainly used for lifting or towing materials in construction, water conservancy projects, forestry, mines, docks, etc.

Reference publication (announcement) number: CN214535428U, discloses a fixed frame of an integrated winch, including a winch body, a rectangular fixed plate slidably connected to the lower end of the winch body, and through the mutual cooperation of the first cross rotary block, the first bevel gear, the second bevel gear, the first screw, the rectangular connecting rod, the second screw, the first straight gear, the third screw and the toothed limit block, the position of the rectangular fixed base of the frame can be effectively adjusted according to the needs of the use environment, so as to adapt to different fixed positions and reduce safety hazards; through the mutual cooperation of the second straight gear, the circular rotary rod, the third straight gear, the fourth screw, the fifth screw, the square fixed plate and the circular connecting rod, the position of the winch can be effectively adjusted according to the needs of use, reducing the wear of the wire rope when winding and improving the service life. In the actual use process, the above device lacks a protective device. Since the towed object is heavy, a large force will be applied to the wire rope. When winding, it cannot ensure that the wire rope is evenly wound on the winding roller, so that the stacked objects rub against each other, which easily leads to the danger of wire rope breakage. In view of this, the present application proposes a winch fixing frame.

DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Referring to Figures 1-3, a winch fixing frame includes a base 1, a plurality of retractable supporting legs 2 are fixedly installed on the lower end of the base 1, a plurality of threaded holes are opened at the bottom of the supporting legs 2, an assembly frame 3 is fixedly installed on the upper surface of the base 1, a motor 5 is installed on the upper surface of the assembly frame 3 through a fixing seat 4, the output shaft of the motor 5 is connected to a body 7 through a transmission wheel 6, a winding device is installed on the side of the body 7 away from the motor 5, the winding device includes a transmission rod, one end of the transmission rod extends into the body 7, the other end of the transmission rod is rotatably connected to an extension plate on the assembly frame 3, two baffles 8 are sleeved on the transmission rod, and a winding roller 9 is installed between the two baffles 8.

A transmission box 11 is installed on the upper end of the assembly frame 3 through a bracket 10. The transmission box 11 is connected to a fixed plate 16 through an internally arranged adjustment device. The adjustment device includes a reciprocating screw 13. A screw nut 14 is threadedly connected to the reciprocating screw 13. A limiting rod 15 is passed through the screw nut 14. Both ends of the reciprocating screw 13 are rotatably connected to the inner wall of the transmission box 11. The limiting rod 15 is slidably connected to the screw nut 14, and the screw nut 14 is connected to the fixed plate 16.

A driving wheel is sleeved on the output shaft of the motor 5, and a driven wheel is sleeved on the reciprocating screw 13, and the driving wheel and the driven wheel are connected by a belt 12. Furthermore, the output shaft of the motor 5 can drive the reciprocating screw 13 to rotate while driving the winding roller 9. Therefore, when adjusting the winding speed of the wire rope, the rotation speed of the reciprocating screw 13 will also change, and the rotating rod 17 can always organize the wire rope.

A support plate is slidably penetrated at the bottom of the fixed plate 16, and both ends of the support plate are fixedly connected to the inner wall of the transmission box 11. Two rotary rods 17 are rotatably connected to the fixed plate 16. It should be noted that the wire rope is passed through the gap between the two rotary rods 17 and fixed on the winding roller 9. The rotary rod 17 rotates to transport the wire rope to the winding roller 9. At the same time, the rotary rod 17 can clean the dirt adhering to the wire rope to avoid contamination of the unused wire rope on the winding roller 9.

When using this device, the base 1 is installed in the working area through the threaded hole at the bottom of the supporting leg 2, one end of the wire rope is passed through between the two rotating rods 17 and fixed on the winding roller 9, the motor 5 is started, and the output shaft of the motor 5 drives the transmission wheel 6 to rotate. Under the operation of the machine body 7, the winding roller 9 is finally driven to rotate through the extended transmission rod, so that the wire rope is wound on the surface to pull the connected heavy object. At the same time, under the transmission connection between the driving wheel, the driven wheel and the belt 12, the output shaft of the motor 5 will drive the reciprocating screw 13 to rotate, and the threaded screw nut 14 will move back and forth along the direction set by the reciprocating screw 13 under the fixation of the limit rod 15, and the fixed plate 16 will move back and forth along the direction set by the reciprocating screw 13. Under the transportation of the rotating rod 17, the wire rope is evenly arranged on the winding roller 9 to prevent the wire ropes from being entangled and rubbed against each other, thereby causing breakage.
