Embodiment Construction

[0024] Examples, see Figure 1-Figure 5 As shown, the automatic centering device of a hoisting machine's rope deflection angle according to the present invention includes a hoisting machine 1 and a supporting body 2, and a rope is wound on the drum 11 of the hoisting machine 1; the hoisting machine 1 can slide along the axial direction of the drum 11. It is arranged on the supporting body 2. When the hoist 1 is in operation, the axial component force of the pulling force on the rope drives the hoist 1 to slide along the direction of the axial component, so that the rope-out angle of the hoist 1 is kept less than or equal to the predetermined set value. The preset value is specifically 2°, which meets the requirements of the national standard GB / T1955-2008. The rope is specifically a steel wire rope 12, but not limited thereto. The supporting body 2, as the carrier of the hoist 1, can have any structure, size, etc., and the supporting body 2 can be a separate component, and i...

Abstract

The invention discloses a device and method for automatic centering of the rope-out deflection angle of a winch. The device comprises the winch and a supporting body, and a rope is wound around a winding drum of the winch; the winch is slidably arranged on the supporting body in the axis direction of the winding drum of the winch, when the winding drum of the winch rotates, an axial component of pulling force applied to the roper drives the winch to slide in the direction of the axial component, and thus the rope-out deflection angle of the winch is kept to be smaller than or equal to a presetvalue. According to the device and method for automatic centering of the rope-out deflection angle of the winch, the service life of the rope is greatly prolonged, the mounting distance between the winch and a fixed pulley can be decreased as much as possible, and thus a construction machinery structure applying the winch can be manufactured to be very compact.

Description

technical field [0001] The invention relates to a winch, in particular to a device and method for automatically centering the rope-out angle of the winch. Background technique [0002] It is relatively common to use hoisting machines on existing construction machinery, and generally adopt fixed machine bases. In order to make the rope deflection angle of the hoist meet the requirements of the national standard GB / T1955-2008, when designing and installing the hoist and the fixed pulley, a large distance needs to be opened between the two to ensure that the rope deflection angle is not greater than 2° . For this reason, the fixed pulley is often installed on the top of the mast or frame of the engineering machinery, and there is a height difference of several meters or even tens of meters from the hoist installed on the supporting body of the engineering machinery. This is not conducive to the realization of compact structure of the whole construction machinery, and the larg...
