Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a portable winch. Background Art

[0002] In industrial production and life, winches are often used to lift and transport equipment, materials, and daily necessities. They are also used to adjust equipment during inspection and maintenance. For example, when installing air-conditioning equipment in a family, the lifting and hoisting of the air-conditioning often takes up the main work. The materials used in house construction and decoration are also used for high-rise lifting and hoisting. In industrial production, the lifting and adjustment of equipment during equipment installation, the pulling of belt conveyor belts, etc. all require the use of winches. Because common winch equipment is large, inconvenient to carry, and the workplace is not flexible, the above lifting operations often bring more inconvenience and waste more time in life. Portable winch equipment is small in size, easy to carry, flexible to use, simple to operate, and low in cost value. It can be widely used in lifting and hoisting operations in life and production.

[0003] For example, a portable winch with patent number CN201820632853.0 includes a winch body, the winch body includes a base and a shield, one end of the base is provided with a rotating shaft 1, the shield is connected to the base through the rotating shaft 1, a lighting lamp is provided in the shield, a fixed platform and a support seat are provided on the top of the base, the fixed platform is installed on one side of the support seat, a hook is provided on the fixed platform, a connecting line is sleeved on the hook, a control switch is provided at one end of the connecting line, a motor is provided on the top of the support seat, a pulley 1 is provided on the output shaft of the motor, a roller 1 and a connecting shaft are provided on one side of the motor, a set of the roller is provided on the connecting shaft, support frames are provided at both ends of the roller 1, and a pulley 2 and a lifting column are provided on one side of the support frame. The portable winch is reasonably designed, convenient to carry and transport, and has a long service life.

[0004] However, this mechanism has the following defects: first, it uses belt drive, which is prone to slipping when carrying heavy objects; second, it is large in size and inconvenient to carry; third, the winding mechanism is external, requiring an additional shell, which increases manufacturing cost and weight.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a portable winch, comprising a motor 3 and a drum 7, characterized in that: the motor 3 and the drum 7 are arranged between two side panels 4 from top to bottom, and the side panels 4 at both ends are fixedly connected by support columns 2 and support rods 9; the motor 3 is connected to the drum 7 through a gear set, comprising a driving gear 5, a transition gear 6 and a passive gear 8, the driving gear 5 and the passive gear 8 are respectively connected to the motor 3 and the drum 7, the transition gear 6 is arranged on the side panel 4, and the motor 3 drives the driving gear 5 to rotate to rotate the drum 7.

[0007] Preferably, three support columns 2 are provided and are horizontally arranged above the side panels 4 at both ends, and a slidable hook 1 is provided on the support column 2; four support rods 9 are provided and are evenly distributed in the middle and below the side panels 4 at both ends.

[0008] Preferably, the driving gear 5 has the smallest diameter, the driven gear 8 has the largest diameter, and the transition gear 6 has a diameter between the two. The three gears are all arranged on the outside of the side plate 4, and a protective cover is provided on the outside of the gears.

[0009] Preferably, the motor 3 is a brake motor.

[0010] Preferably, both ends of the support column 2 and the support rod 9 are provided with steps and threads, and are fixed to the side plate 4 by nuts.

[0011] Compared with the prior art, the beneficial effects of the utility model are: first, the winding mechanism is arranged on the inner side of the side plate, reducing the protective cover and weight; second, the use of a brake motor and a gear mechanism can avoid slipping when carrying heavy objects; third, it is small in size and easy to carry; fourth, a hook is provided to improve work efficiency.
