Abstract
An industrial furnace door with guide rails is composed of a trolley (1), two hydraulic cylinders (2), trolley door columns (3), an outer-layer sliding door rack (4), an inner-layer sliding door rack (5), chain wheels (6) and roller chains (7). The industrial furnace door is characterized in that piston rods of the two hydraulic cylinders (2) stretch out to drive the four chain wheels (6) to move upwards along the rails in the trolley door columns (3), and the inner-layer sliding door rack (5) is made to move upwards along inner side rollers of the outer-layer sliding door rack (4) for the distance two times that of the outer-layer sliding door rack (4). According to the industrial furnace door, due to the fact that the two linear rails are arranged in a door frame of the furnace door, the furnace door can stably move up and down in the rails, the opening and closing stability of the furnace door is guaranteed, the running stability of a furnace is improved, and the air leakage phenomenon in the use process is reduced.
Description
Technical field
The present invention relates to a kind of a kind of fire door being 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-furnace temperature is all for a condition of high temperature, after Long-Time Service, the thermal deformation of fire door can make fire door warpage etc., produce irregular deformable body, this can make coordinating between furnace door body with body of heater change, thus produce the phenomenons such as fire door gas leakage, be unfavorable for the use of industrial furnace, therefore need to change the door structure of industrial furnace of the prior art, the harm that oven door sealing is brought is out of shape to eliminate fire door.Also meet the call that national energy-saving reduces discharging simultaneously.
For above problem, the object of this reality invention is to provide a kind of industrial furnace fire door with guide rail, by the movement locus of double-layer guide rail restriction fire door, by the length of adjusting device adjusting chain, thus reduces 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 dolly, two hydraulic cylinders, dolly door pillar, outer slip door frame, internal layer slip door frame, sprocket wheel and roller chain composition, one end of hydraulic cylinder by stud connection on dolly door pillar, the top of the piston rod of hydraulic cylinder is connected on outer slip door frame, four sprocket wheels are arranged in the crossbeam of outer slip door frame, it is characterized in that: the piston rod of two described hydraulic cylinders stretches out, four sprocket wheels are driven to move upward along the track in dolly door pillar, make internal layer slip door frame double outer slip door frame along the interior side wheel of outer slip door frame to move upward.
Two described hydraulic cylinders drive sprocket, and dolly moves up or down along the internal layer slip door frame in dolly door pillar under the effect of roller chain.
The present invention, owing to being provided with two rectilinear orbits in Furnace door frame inside, fire door can move up and down in track more stably, thus ensure that the stability of door opening and closing, improves the stability that stove and accessory runs, and the gas leak phenomenon reduced in use procedure occurs.

Detailed description of the invention
By Fig. 1, Fig. 2 knows, a kind of industrial furnace fire door with guide rail, by dolly 1, two hydraulic cylinders 2, dolly door pillar 3, outer slip door frame 4, internal layer slip door frame 5, sprocket wheel 6 and roller chain 7 form, one end of hydraulic cylinder 2 by stud connection on dolly door pillar 3, the top of the piston rod of hydraulic cylinder 2 is connected on outer slip door frame 4, four sprocket wheels 6 are arranged in the crossbeam of outer slip door frame 4, the piston rod of two described hydraulic cylinders 2 stretches out, four sprocket wheels 6 are driven to move upward along the track in dolly door pillar 3, make internal layer slip door frame 5 double outer slip door frame 4 along side wheel in skin slip door frame 4 to move upward.Two hydraulic cylinders 2 are with movable sprocket 6 to move, and dolly 1 moves up or down along the internal layer slip door frame 5 in dolly door pillar 3 under the effect of roller chain 7.
Claims (2)
1. the industrial furnace fire door with guide rail, by dolly (1), two hydraulic cylinders (2), dolly door pillar (3), outer slip door frame (4), internal layer slip door frame (5), sprocket wheel (6) and roller chain (7) composition, one end of hydraulic cylinder (2) by stud connection on dolly door pillar (3), the top of the piston rod of hydraulic cylinder (2) is connected on outer slip door frame (4), four sprocket wheels (6) are arranged in the crossbeam of outer slip door frame (4), it is characterized in that: the piston rod of two described hydraulic cylinders (2) stretches out, four sprocket wheels (6) are driven to move upward along the track in dolly door pillar (3), make internal layer slip door frame (5) double outer slip door frame (4) along the interior side wheel of outer slip door frame (4) to move upward.
2. a kind of industrial furnace fire door with guide rail according to claim 1, it is characterized in that: two described hydraulic cylinder (2) band movable sprocket (6) motions, dolly (1) moves up or down along the internal layer slip door frame (5) in dolly door pillar (3) under the effect of roller chain (7).
