Auxiliary hoisting device of construction hoist

Abstract

The invention discloses an auxiliary hoisting device of a construction hoist. The auxiliary hoisting device is used for hoisting and installing a motor variable-speed motor of the construction hoist. The auxiliary hoisting device comprises a stand column, a winch and a cross arm, wherien the bottom of the stand column is fixedly connected to a fixing point of the hoist, the top of the stand column is fixedly connected to the cross arm, the winch is fixed to the stand column, pulleys are arranged at the top of the stand column and the tail end of the cross arm correspondingly, a cable of the winch is wound around the pulleys to be connected to a to-be-hoisted piece, the stand column is provided with a hollow outer column body and a lifting column, the lifting column is arranged in the outer column body in a sleeve mode, a hydraulic jack is further arranged in the outer column body, the bottom of the hydraulic jack is fixed to the outer column body, the top of the hydraulic jack makes contact with the bottom of the lifting column, and the hydraulic jack is used for controlling the height of the lifting column.

Description

technical field [0001] The present application relates to the technical field of engineering machinery, in particular to an auxiliary hoisting device for a construction hoist. Background technique [0002] The construction elevator is also called the construction elevator. The construction elevator is composed of a car, a drive mechanism, a standard section, an attached wall, a chassis, a fence, and an electrical system. The unique box structure makes it comfortable and safe to ride. The construction hoist is usually used with the tower crane on the construction site. The general load capacity is 0.3-3.6 tons, and the operating speed is 1-96M / min. [0003] Cables, motors, and gearboxes are generally installed on construction elevators. In the prior art, when installing or maintaining equipment such as cables, motors, and gearboxes, these devices are usually manually lifted to the installation point or removed from the installation. However, because the equipment is relative...

Problems solved by technology

[0003] Cables, motors, and gearboxes are generally installed on construction elevators. In the prior art, when installing or maintaining equipment such as cables, motors, and gearboxes, these devices are usually manually lifted to the installation point or removed from the installation. However, because the equipment is relatively heavy, it brings great difficulties to the construction staff, and once the equipment slips, it may cause serious safety accidents, and the safety is very low. Therefore, there is an urgent need for a safe and convenient Auxiliary device
