Abstract

The invention discloses a pit type furnace lifting device. The pit type furnace lifting device comprises a wall body and a furnace door, a motor is fixed on the outer wall of the wall body through a mounting seat, the output end of the motor is rotationally connected with a shaft rod, the outer wall of the shaft rod is sequentially sleeved with limiting seats, the limiting seats are arranged at the outer end of the wall body, a top beam is fixed to the top end of the shaft rod through a reinforcing plate, a hydraulic cylinder is arranged on the top beam, a control rod is fixed at the output end of the bottom of the hydraulic cylinder, a lifting table is arranged at the lower end of the control rod, the furnace door is fixed on the lifting table, and each limiting seat internally comprisesa limiting seat body and a base. According to the pit type furnace lifting device, the motor, the limiting seats, a spiral groove, the shaft rod, the reinforcing plate, the top beam, the hydraulic cylinder, the lifting table, a spring, a limiting cavity, a ball and a limiting through hole are arranged, so that the problems that when a pit type furnace lifting device is used at the present stage, lifting and rotating can not be performed at the same time, the stability is poor, and potential safety hazards exist during use are solved.

Description

technical field [0001] The invention relates to the technical field of boiler equipment, in particular to a well type furnace lifting device. Background technique [0002] At present, the pit furnace is a periodic operation furnace, which is suitable for heat treatment of rods and long shaft parts. The structure of the well-type furnace is: the furnace body is a cylindrical deep well, and the workpiece is vertically loaded into the furnace by a special crane for heating. The fuel used is usually gas and oil. When electricity is used as the heat source, it is called a well-type resistance furnace. The pit furnace is generally placed below the ground level of the workshop, and some are placed above the ground level, or half above and below the ground level. The names of well-type furnaces include: forced convection well-type furnace, natural convection well-type furnace, well-type gas carburizing furnace, etc. When the boiler is in use, the furnace door part needs to be fre...
