Abstract
An industrial furnace door with guide rails comprises a main sprocket assembly (1), an auxiliary sprocket assembly (2), a main chain (3), an auxiliary chain (4), a door frame (6), a bearing assembly (8), an adjusting device (9) and a furnace door body (10) and is characterized in that one end of the main chain (3) is fixed on the main sprocket assembly (1) and is connected one end of the furnace door body (10) through the auxiliary sprocket assembly (2), one end of the auxiliary chain (4) is connected with the furnace door body (10) and connected with counter weight (5) through the main sprocket assembly (1), and the adjusting device (9) is disposed at the connection of the auxiliary chain (4) and the furnace door body (10). Due to the fact that two linear rails are disposed inside the door frame of the furnace door, the furnace door can move up and down stably in the rails, opening and closing stability of the furnace door is guaranteed, furnace operation stability is increased, and gas leakage during use is reduced.
Description
Technical field
The present invention relates to a kind of a kind of fire door that is applied to industrial furnace, be particularly applied in a kind of industrial furnace fire door with guide rail on chassis tempering furnace.
Background technology
The fire door that present stage coordinates with chassis tempering furnace is divided into laterally opened according to large I, opposite opened and lift, it is laterally opened that sealing effectiveness is relatively good comparatively speaking with opposite opened, but the sealing property of lifting furnace door is poor comparatively speaking, fire door when in use, in stove, temperature is all for a condition of high temperature, after long-term use, the thermal deformation meeting of fire door makes fire door warpage etc., produce irregular deformable body, this can make coordinating between furnace door body and body of heater change, thereby produce the phenomenons such as fire door gas leakage, be unfavorable for the use of industrial furnace, therefore need the door structure of industrial furnace of the prior art to change, be out of shape to eliminate fire door the harm that oven door sealing is brought.Also meet the call that national energy-saving reduces discharging simultaneously.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of industrial furnace fire door with guide rail, limit the movement locus of fire door by double-layer guide rail, by the length of adjusting device adjusting chain, thereby reduce fire door distortion.
Technical scheme of the present invention is achieved in the following ways: a kind of industrial furnace fire door with guide rail, by head sprocket assembly, auxiliary chain wheel assembly, main chain, secondary chain, doorframe, bearing assembly, adjusting device and fire door composition, reductor is fixed on the one end on the top of doorframe, reductor and head sprocket assembly link together, auxiliary chain wheel assembly is arranged on the other one end on doorframe top, fire door left and right structural steel outer wall is provided with two symmetrical bearing assemblies, it is characterized in that: described main chain one end is fixed on head sprocket assembly, by being connected with one end of fire door after auxiliary chain wheel assembly, secondary chain one end is connected with fire door, by being connected with counterweight after head sprocket assembly, secondary chain and fire door junction are also provided with adjusting device.
The left and right structural steel inwall of described doorframe is respectively arranged with two rectilinear orbits, and track end is provided with limited block.
Described reductor drives the motion of head sprocket assembly, and fire door moves up or down along the rectilinear orbit in doorframe under the effect of main chain.
Described adjusting device, for regulating the length of the secondary chain in two ends, keeps main chain consistent with secondary chain length, makes fire door stable operation.
The present invention, owing to being provided with two rectilinear orbits in fire door doorframe inside, fire door moves up and down in track more stably, thereby has ensured the stability of door opening and closing, has improved the stability of stove and accessory operation, and the gas leak phenomenon reducing in use procedure occurs.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
