Stage hydraulic driving and damping fireproof isolation equipment

Abstract

Disclosed is stage hydraulic driving and damping fireproof isolation equipment. A damping oil cylinder (4) is connected with a hydraulic control system (1). The upper end of a rectangular isolation body (6) is connected with steel wire ropes (11). The steel wire ropes (11) are correspondingly fixedly connected with a wall body through corresponding pulley blocks (10) and a movable pulley which is at the upper end of a stand rod and winds across the damping oil cylinder (4). One side of the isolation body (6) is provided with a guide rail travel switch (5) and an extreme position sensor (9) which supplies oil to the oil cylinder. The ends of the steel wire ropes (11) are connected with the isolation body (6) through rope clips (12), rigging thimblers (13) and rigging turnbuckles (14) for a ship. A hydraulic oil box (29) of the hydraulic control system (1) is provided with a distribution box (2), a liquid level meter (7), a filter (16), a lifting hook (31), an oil draining plug (33) and an isolation box (30). An electromotor (18) is arranged in the isolation box (30). A power input shaft of a hydraulic pump (17) is connected with an output shaft of the electromotor (18) through a coupler (15).

Description

technical field [0001] The invention relates to the technical field of stage machinery, in particular to stage fireproof isolation technology. Background technique [0002] The use of electrical appliances in modern stage equipment and large buildings is becoming more and more extensive, and fires caused by improper use of electrical appliances often occur and are difficult to control. When a stage or a part of a building catches fire, it should be cut off from the non-fired part in time to effectively limit the fire to the minimum range, prevent the fire from being controlled, and reduce losses. Therefore, in stage equipment and large buildings, fire isolation devices should be installed where required. The existing fire isolation device has many shortcomings, such as the need to use a winch lifting system to add counterweight or use a long oil cylinder with a stroke of more than 10 meters (currently not produced in China), hydraulic motor damping, complex hydraulic system...
