The face is a right triangle; the left door (11) also includes a left walking mechanism (34) and a left counterweight (35); the right frame (23) includes a right-right frame (41), a right-middle frame (42) and a right-left frame (43), and the right door (12) also includes a right walking mechanism (44) and a right counterweight (45); the left door (11) and the right door (12) are symmetrically arranged. This utility model has a simple structure, compact space arrangement, good heat insulation effect, low energy consumption and high reliability.

[0004] In the process of realizing this application, the inventors discovered the following problems with the prior art: When existing fire doors are in use, because they are close to high-temperature objects, after a long period of use, the moving track below them will be damaged due to the impact of high-temperature materials falling. Most existing fire doors are single-track, and after the track is damaged, it is not convenient to replace it, resulting in poor practicality.

[0005] Therefore, those skilled in the art have provided a double-track furnace front fire baffle to solve the problems mentioned in the background art. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a double-track furnace front fire baffle. Through the design of a double-track mechanism and a track-changing mechanism, it reduces downtime caused by track damage, improves production efficiency, and lowers production costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A double-track furnace front fire baffle includes a double-track mechanism, a track-changing mechanism is provided on one side of the double-track mechanism, and a main body mechanism is provided on the surface of the double-track mechanism;

[0009] The track-changing mechanism includes a track-changing base plate, on the upper surface of which two limiting blocks are fixedly arranged, and a track-changing track is slidably arranged on the upper surface of the two limiting blocks.

[0010] Furthermore, a track-changing motor is fixedly installed on one side of the track-changing track, and a reducer is fixedly installed at the output end of the track-changing motor.

[0011] Furthermore, a variable track gear is fixedly installed at the output end of the reducer.

[0016] Furthermore, multiple drive motors are fixedly installed at the bottom of the fire door body, and movable wheels are fixedly installed at the output ends of the multiple drive motors.

[0017] This utility model has the following beneficial effects:

[0018] 1. The present invention proposes a double-track furnace front fire baffle. Compared with existing fire baffles, this fire baffle is equipped with a track-changing mechanism. When in use, the fire baffle body can switch between two sets of tracks. When one set of tracks is damaged, the fire baffle body can be easily moved to another set of tracks through the cooperation of the track-changing motor, reducer, track-changing gear and track-changing rack, so as to repair or replace the damaged track, thereby avoiding production interruption caused by track damage, reducing maintenance time and cost, and improving the service life of the track and the reliability of the equipment.

[0019] 2. The present invention proposes a double-track furnace front fire baffle door. Compared with existing fire baffle doors, this fire baffle door is equipped with a double-track mechanism. When in use, the main body of the fire baffle door can switch between two sets of tracks. When one set of tracks is damaged due to high-temperature material falling or other reasons, it can quickly switch to the other set of tracks to avoid production interruption caused by track damage. This allows the two sets of tracks to be used alternately, reducing the frequency of use and wear of a single set of tracks, thereby extending the service life of the tracks, reducing downtime caused by track repair or replacement, and improving equipment availability and production efficiency.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 2 One embodiment provided by this utility model:

[0028] A double-track furnace front fire baffle includes a double-track mechanism 2, a track-changing mechanism 3 is provided on one side of the double-track mechanism 2, and a main body mechanism 1 is provided on the surface of the double-track mechanism 2.

[0029] Specifically, the dual-track mechanism 2 allows users to select the appropriate track for use, the track-changing mechanism 3 facilitates track replacement and repair of damaged tracks, and the main body mechanism 1 enables the device to fulfill its basic function as a fire door.

[0030] Reference Figure 3 , Figure 4The track-changing mechanism 3 includes a track-changing base plate 306. Two limit blocks 307 are fixedly installed on the upper surface of the track-changing base plate 306. A track-changing track 302 is slidably installed on the upper surface of the two limit blocks 307. A track-changing motor 302 is fixedly installed on one side of the track-changing track. A reducer 303 is fixedly installed at the output end of the track-changing motor 302. A track-changing gear 304 is fixedly installed at the output end of the reducer 303. A track-changing rack 305 is fixedly installed at one end of the upper surface of the track-changing base plate 306.

[0031] Specifically, when using the device, if one set of tracks in the dual-track mechanism 2 is damaged and needs to be replaced, the user can move the main body mechanism 1 to the surface of the track 302 of the track-changing mechanism 3. After the movement is completed, the track-changing motor 302 rotates, which in turn drives the track-changing gear 304 to rotate in conjunction with the reducer 303. The track-changing gear 304 meshes with the track-changing rack 305, thereby driving the track 302 to slide along the limit block 307 and move to the other set of tracks in the dual-track mechanism 2, whereby the user can replace the damaged track.

[0032] The dual-track mechanism 2 includes a first base plate 202, a second base plate 204 fixedly disposed on one side of the first base plate 202, a first track 201 fixedly disposed on the upper surface of the first base plate 202 by bolts, and a second track 203 fixedly disposed on the upper surface of the second base plate 204 by bolts.

[0033] Specifically, by providing a first track 201 and a second track 203, the fire door body 101 can be moved on the surface of the first track 201 and the second track 203 by the moving wheels 103 during use, so as to open and close the two fire door bodies 101. By providing a first base plate 202 and a second base plate 204, when a track is damaged, the user can remove the damaged track from the first base plate 202 or the second base plate 204 for replacement.

[0034] The main structure 1 includes a fire door body 101. A maintenance platform 104 is fixedly installed in the middle of the front of the fire door body 101. A ladder 105 is fixedly installed on one side of the maintenance platform 104. Multiple drive motors 102 are fixedly installed at the bottom of the fire door body 101. Moving wheels 103 are fixedly installed at the output end of the multiple drive motors 102.

[0035] Specifically, during use, the fire door body 101 facilitates the basic function of the device as a fire door. The maintenance platform 104 and ladder 105 facilitate daily maintenance of the device by the user. The moving wheels 103 and drive motor 102 enable the two fire door bodies 101 to open and close during use.

[0036] Working principle: When the device is in use, the moving wheels 103 at the bottom of the fire door body 101 are driven by the drive motor 102 to move on the first track 201 and the second track 203, realizing the opening and closing operation of the fire door. At the same time, the maintenance platform 104 and the ladder 105 facilitate the daily maintenance and repair by the operators. When a set of tracks is damaged and needs to be replaced, the track changing mechanism 3 can move the fire door body 101 from the damaged track to another set of intact tracks. When performing the track changing operation, the track changing motor 302 rotates, which drives the track changing gear 304 to rotate through the reducer 303. The track changing gear 304 meshes with the track changing rack 305, thereby driving the track changing track 301 to slide along the limit block 307, moving the fire door body 101 from the damaged track to another set of intact tracks, after which the damaged track can be replaced.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
