Embodiment Construction

[0029] Examples of hoist devices are Figure 1~10 Shown: including lever hoist 2 and electric wrench 1, lever hoist 2 includes hoist bracket, rotating parts and handle 4, rotating parts include sprocket and ratchet, sprocket is used for chain winding, handle is provided with for The ratchet is driven by the ratchet, and the handle is provided with an operating twist, which can control the transmission and disengagement of the ratchet and the ratchet. For example, the operation is twisted to a position, and the ratchet and the ratchet are matched. The parts are driven, so that the chain can retract and release heavy objects, and the operation is twisted to another position. The ratchet and the pawl are no longer transmitted. At this time, the handle is no longer transmitted with the rotating parts. The rotating part is also fixedly provided with a hand wheel 3, and the hand wheel is suitable for driving the rotating part to retract the chain when it is empty. The matching rela...

Abstract

The invention relates to a hand wheel, a lever hoist comprising the same and a hoist device. The lever hoist comprises a hoist frame, wherein a rotating assembly comprising a chain wheel and a ratchetwheel is rotationally arranged on the hoist frame; a handle in transmission fit with the ratchet wheel through a pawl is also arranged on the hoist frame; an operation button for controlling transmission or disconnection of the pawl and the ratchet wheel is arranged on the handle; the lever hoist further comprises the hand wheel, the hand wheel comprises a hand wheel body fixedly connected with the rotating assembly, and an electric wrench connecting structure in rotation-stopping transmission connection with the corresponding torque output end of an electric wrench is arranged on the hand wheel body. The invention provides the hoist device capable of realizing manual operation and electric operation.

Description

technical field [0001] The invention relates to a hand wheel, a lever hoist and a hoist device using the hand wheel. Background technique [0002] In the construction of power transmission and distribution lines, the lever hoist is the main tool for tightening and loosening wires at high altitudes, fixing construction equipment, adjusting wires for towers, and fastening ground wires. [0003] The existing lever hoist includes a hoist bracket, a rotating part and a handle. The rotating part includes a sprocket and a ratchet. The sprocket is used for the chain to wind around. Twist, the operation twist can control the transmission and disengagement of the ratchet and the ratchet. For example, the operation is twisted to a position, and the ratchet and the ratchet cooperate. The operation is twisted and pushed to another position, the ratchet and the pawl are no longer transmitted, and the handle is no longer transmitted with the rotating parts. It is suitable for use when ret...
