The invention provides a quick conveying device at densely covered fire evacuation exits on market floors. On each floor passage of a market, evacuation exits leading to the lower layers are arranged at intervals, a gliding platform below each evacuation exit is hinged with the upper end of a main frame body of a conveying slide through a pivot, two sides of the lifting end of the main frame body of the conveying slide are connected with dragging ropes, a lifting and locking device is arranged below each floor, telescopic pipes are sleeved outside the dragging ropes, rollers are arranged on the slideway plane of the conveying slide, a damping device is arranged on the lower end surface of the slideway, guardrails on two sides of the slideway are provided with supporting mechanisms, and ring-shaped rotating belts of the supporting mechanisms are encircled in grooves around the guardrails. According to the invention, as the evacuation exits are densely covered on the passages of the floors, people can find the evacuation exits quickly and escape the fire fields immediately. The conveying slide has a simple structure, saves the manufacturing cost, can safely and quickly convey people, and is transversely clung to the top of the floor when waiting for orders, thereby not influencing the indoor attractiveness and being suitable for various large-scale public buildings. |
