Hoisting device for construction equipment

Abstract

The invention provides a hoisting device for construction equipment. The hoisting device comprises a hook, a lock catch, a torsional spring, a bent lever and an extension spring, wherein the lock catch is pivoted at the upper part of the hook; the lower end of the lock catch extends toward a lower-end arm of the hook; the lock catch is used for blocking an opening of the hook; the torsional springis sleeved on a pin shaft of the hook; one end of the torsional spring presses on the lock catch; the other end of the torsional spring presses on an upper-end arm of the hook; the bent lever is pivoted on the outer wall of the lower-end arm; a clamping rod at the front end of the bent lever can be clamped on a hooking part at the lower end of the lock catch; the upper end of the extension springis connected with a bent part of the bent lever; and the lower end of the extension spring is connected with a positioning rod of the lower-end arm. According to the hoisting device for constructionequipment, above structure is adopted, so that in the process of hoisting steel ropes, the steel ropes are firmly fixed by the lock catch and the steel ropes are prevented from being divorced from thehook in the hoisting process, thereby enabling the equipment to effectively work for a long time, improving the working efficiency and enhancing the safety factors of the equipment.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a hoisting device for construction equipment. Background technique [0002] With the advancement of science and technology and the development of economy, the rapid development of the construction industry has been driven, and the development of supporting equipment has also been promoted. During construction, large construction equipment such as cranes and hoists are required for a long time. Most of the construction sites now cannot meet the space and conditions required by large equipment, and when handling small pieces, it is a waste of resources. [0003] Chinese patent CN201711478851.7 discloses a variety of hoisting devices for construction equipment, including a main body, a round block and a hanging block. The upper end of the main body is provided with a round block, the right side of the main body is provided with a horizontal plate, and the lower end of...
