A pit-type furnace with split lid for easy installation of slings

Abstract

The invention discloses a pit furnace with a double furnace cover convenient for installing a lifting appliance. Parallel tracks are arranged at the outer side of the furnace cover and two opposite track trolleys are arranged on the tracks. The frame of each track trolley is fixed onto the corresponding track by multiple pairs of opposite wheels. The opposite wheels in each pair are fixed to each other by a connecting shaft and one of the connecting shafts is connected with a traveling motor by a transmission mechanism. A screw rod lifting mechanism is arranged in the middle of the frame of each track trolley and the screw rod lifting mechanisms are fixedly connected with the furnace cover. A trapezoid supporting frame is arranged at the upper portion of the frame of each track trolley and a U-shaped limiting groove is arranged in each trapezoid supporting frame. One end of the lifting appliance is hung into the opposite U-shaped limiting grooves of the two track trolleys and the other end of the lifting appliance extends into a furnace body through a connecting rod. The pit furnace is low in production cost, high in product efficiency, good in service safety, capable of hanging the lifting appliance into the furnace body conveniently and rapidly, convenient and rapid to operate and capable of saving both time and labour.

Description

technical field [0001] The invention belongs to the technical field of heating equipment, and in particular relates to a pit-type furnace with a furnace cover that is convenient for installing a sling. Background technique [0002] When the pit-type furnace in the prior art is in use, the furnace cover on the furnace body is opened and closed by crane, and the whole opening and closing time is longer, resulting in longer production cycle and lower production efficiency, and when hoisting, Because the driving is high from the ground, the shaking is large and it is easy to scratch the workers, the safety is poor, and it involves the workpiece that needs to be suspended for heating. During the furnace loading process, two lifting equipment need to be used at the same time, which is costly and extremely inconvenient to operate. . Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a split-lid type well-type furnace with...

[0002] When the pit-type furnace in the prior art is in use, the furnace cover on the furnace body is opened and closed by crane, and the whole opening and closing time is longer, resulting in longer production cycle and lower production efficiency, and when hoisting, Because the driving is high from the ground, the shaking is large and it is easy to scratch the workers, the safety is poor, and it involves the workpiece that needs to be suspended for heating. During the furnace loading process, two lifting equipment need to be used at the same time, which is costly and extremely inconvenient to operate.
