Problems solved by technology

The commonly used cranes have high requirements on the tension of the lifting cables when lifting heavy materials, and they are lifted vertically alone. Due to environmental influences, the materials are prone to shake during the lifting process, further increasing the tension on the cables, and there are potential safety hazards.

Abstract

The invention discloses lifting equipment. A first lifting device, a second lifting device, a third lifting device and a fourth lifting device are arranged above a rack; the first lifting device and the second lifting device are oppositely arranged; the third lifting device and the fourth lifting device are oppositely arranged; each lifting device comprises a take-up roll, a fixed pulley and a guide wheel located between the take-up roll and the fixed pulley; two ends of two lifting ropes are respectively connected with a group of opposite take-up rolls; a movable pulley is arranged in the middle of each lifting rope; and two movable pulleys are fixedly connected with each other through a connecting rod. The lifting equipment disclosed by the invention is reasonable in structure design; and heavy materials are lifted through two groups of lifting ropes with the movable pulleys, so that on the one hand, the tension on a single lifting rope can be relieved; and on the other hand, an isosceles triangle is formed by the two movable pulleys and the material in the lifting process, the stress balance of the material is kept and the material cannot be shaken easily.

Description

technical field [0001] The invention relates to the technical field of hoisting, in particular to a hoisting device. Background technique [0002] The hoisting machinery used in bridge construction projects can generally be divided into light and small hoisting equipment, bridge type hoisting machinery, jib type cranes, and cable cranes according to their structure and performance. Light and small lifting equipment such as: jacks, pneumatic hoists, electric hoists, balance hoists (also known as balance cranes), winches, etc.; bridge type lifting machinery such as beam cranes, etc.; Cranes, truck cranes, tire cranes, crawler cranes, etc. The commonly used cranes have high requirements on the pulling force of the lifting cables when lifting heavy materials, and they are lifted vertically alone. Due to environmental influences, the materials are prone to shaking during the lifting process, further increasing the pulling force on the cables, and there are potential safety hazar...
