Track anti-falling device and electrolytic copper lead zinc multifunctional bridge crane

Abstract

The invention relates to the technical field of cranes, and discloses a track anti-falling device applied to a crane. The track anti-falling device comprises a stroke track and a hoist track. A firstconnecting plate is fixed to the stroke track and provided with first protrusion parts protruding from the width of the stroke track in the width direction. A second connecting plate is fixed to the hoist track and provided with second protrusion parts protruding from the width of the hoist track in the width direction. An insulator is arranged between the first connecting plate and the second connecting plate. The track anti-falling device further comprises an anti-falling hook structure. The anti-falling hook structure is provided with a hook part adhered and fixed to the surfaces, facing the hoist track, of the second protrusion parts, and a baffle part which falls with the hoist track when the hoist track falls down so as to abut against the first protrusion parts. The additionally arranged anti-falling hook structure is fixed to the second connecting plate, when falling tendency occurs, the baffle part makes contact with the first connecting plate, and through mutually connectionand restricting function of the hook part and the baffle part, the hoist track and the stroke track are prevented from falling and separating.

Description

technical field [0001] The invention relates to the technical field of cranes, in particular to a rail anti-dropping device and an electrolytic copper-lead-zinc multifunctional bridge crane. Background technique [0002] Electrolytic copper-lead-zinc multi-functional bridge crane is a special equipment used for handling cathode and anode plates in the refining copper-lead-zinc process engineering. Or simultaneous lifting and transfer of yin and yang, with additional functions such as short-circuit detection between tanks and sporadic lifting of objects. [0003] Electrolytic copper, lead and zinc multi-functional bridge cranes hoist and transfer cathode and anode plates mainly through travel rails and hoist rails. The hoist rails move back and forth on the travel rails, but the weight of the lifted objects mainly depends on the hoist rails. There are insulators or bolts connected between the gourd track and the stroke track. In the track insulation installation, the insulat...

Problems solved by technology

[0003] Electrolytic copper, lead and zinc multi-functional bridge cranes hoist and transport cathode and anode plates mainly through travel rails and hoist rails. The hoist rails move back and forth on the travel rails, but the weight of the lifted objects mainly depends on the hoist rails. There are insulators or bolts connected between the gourd track and the travel track. In the track insulation installation, the insulator or bolts have poor tensile strength, and they are prone to aging, fatigue or brittle fracture over time. In severe cases, they may As a result, the hoist track and the travel track were separated, and the hoist track accidentally fell to the ground, causing a major safety accident
