Bridge crane damping device

Abstract

The invention relates to a damping device, in particular to a bridge crane damping device. The bridge crane damping device can control the balance of a main beam. According to the technical scheme, the bridge crane damping device comprises a crane, and the crane comprises two walking end beams, two damping bins, a main beam, a crane car and the like; the two walking end beams are correspondingly arranged on two rails, the lower sides of the two damping bins are fixedly connected to the upper sides of the two walking end beams correspondingly, the two ends of the main beam are correspondingly arranged above the two damping bins, and the crane car is arranged on the upper side of the main beam. The effects are achieved, the crane car is controlled to lift goods, the downward movement speed of a hydraulic plug is gradually reduced from high to low, the damping and buffering functions of the main beam are achieved, and the situation that a lifting hook, a lifting rope, the crane car, the main beam and other parts are impacted and deformed or damaged, and safety accidents occur due to static inertia of the goods is avoided.

Description

technical field [0001] The invention relates to a damping device, in particular to a damping device for a bridge crane. Background technique [0002] The bridge crane is a lifting device that is horizontally placed over the workshop, warehouse and stockyard for material lifting. Because its two ends are located on tall concrete pillars or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated sides on both sides, which can make full use of the space under the bridge frame to lift materials without being affected. It is the most widely used and the largest number of lifting machinery. [0003] The main girder of existing bridge cranes is mostly rigidly connected to the movable end girders at both ends without shock absorbing devices. When beams, cranes and slings are suddenly pulled downward by the goods, they will be impacted by a large force. Long-term use will cause deformation or damage ...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the rigid connection between the main girder of the existing bridge crane and the moving end girders at both ends, there is no shock absorbing device. When the crane on the upper side of the main girder lifts the goods, due to the static inertia of the goods, , the main girder, the crane and the sling will be impacted by a large force when they are suddenly pulled downward by the cargo. Long-term use will cause deformation or damage to various parts of the crane, which will affect the service life of the crane. In severe cases, the crane suddenly Due to the downward pull of the goods, the crane components are damaged and safety accidents occur. The invention provides a shock absorber for bridge cranes
