[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a lifting rack for the door of a wood drying kiln, including a lifting rack 1, a screw lift 2 is fixedly connected to the lower front part of the lifting rack 1, a hook 5 is fixedly connected to the outer side of the upper part of the screw lift 2, a rope 6 is arranged on the outer side of the hook 5, one end of the rope 6 is fixedly connected to a tripod 8, one side of the tripod 8 is fixedly connected to a rotating rod 9, both ends of the rotating rod 9 are fixedly connected to a fixed plate 10, one end of the fixed plate 10 is rotatably connected to a rotating hook 11, a lubrication component is arranged on the upper outer side of the lifting rack 1, and the lifting Two guide wheels 16 are arranged on the top of the frame 1, and a slide rail 17 is arranged on the outside of the guide wheel 16. Two slide grooves are opened at the rear of the lifting frame 1, and a slide rod 18 is fixedly connected inside the slide groove. Two springs 19 are sleeved on the outside of the slide rod 18, and two sliders 20 are slidably connected to the outside of the slide rod 18. The rear part of the slider 20 is rotatably connected to a connecting rod 21, and the rear end of the connecting rod 21 is rotatably connected to a protective plate 22. A sleeve 3 is fixedly connected to the middle part of the rear side of the lifting frame 1, and a spring 7 is fixedly connected to the inner wall of the sleeve 3, and a thin rod 4 is fixedly connected to one end of the spring 7.

[0033] Specifically, the operator matches the rotating hook 11 with the hook on the drying kiln door, and then activates the core power of the screw elevator 2, causing the hook 5 to move downward, which in turn drives the rope 6 and further drives the tripod 8. This series of actions triggers the rotation of the rotating rod 9, which in turn drives the fixed plate 10 to rotate, indirectly driving the rotation of the rotating hook 11, so that the drying kiln door is lifted from the ground until it touches the protective plate 22. When the door continues to rise, it will exert pressure on the protective plate 22, causing the connecting rod 21 to rotate accordingly. This rotation causes the slider 20 to move on the slide rod 18, further compressing the spring 2 19. Finally, the door and the protective plate 22 reach a tightly fitted state.

[0034] Reference Figure 5 The lubrication assembly includes a lubrication box 12, the bottom of the lubrication box 12 is fixedly connected to the middle side of the top of the lifting frame 1, an input pipe 14 is fixedly connected to the middle side of the top of the lubrication box 12, a sponge brush 15 is fixedly connected to the top of the input pipe 14, and a water pump 13 is arranged on the outside of the input pipe 14.

[0035] Specifically, at the current stage, the task of starting the driving water pump 13 is to draw the lubricating oil in the lubrication box 12 and accurately deliver it to the inside of the sponge brush 15 through the input pipe 14. After completing this action, just gently push the drying kiln door, it can smoothly move horizontally along the preset slide rail 17, and in this process, the slide rail 17 is also fully lubricated and protected.

[0036] Reference Figure 1 - Figure 3 The outer side of the rotating rod 9 is rotatably connected to the inside of the lifting frame 1, the outer side of the slider 20 is slidably connected in the slide groove, the bottom of the sponge brush 15 is fixedly connected to the middle side of the top of the lifting frame 1, and the guide wheel 16 moves horizontally on the slide rail 17. One end of the spring 19 is fixedly connected to the inner wall of the lifting frame 1, and the other end of the spring 19 is fixedly connected to one side of the slider 20. The outer side of the thin rod 4 is slidably connected to the inside of the sleeve 3, and one end of the thin rod 4 is fixedly connected to the middle part of one side of the protective plate 22. One side of the sponge brush 15 is slidably connected to one side of the slide rail 17.

[0037] Specifically, the external structure of the rotating rod 9 is closely connected with the inside of the lifting frame 1 to ensure that it can drive the overall movement. The slider 20 forms a sliding fit with the slide groove on the outside to maintain its flexible movement. The sponge brush 15 is firmly installed in the top center of the lifting frame 1 to achieve lubrication of the slide rail 17. The guide wheel 16 slides freely on the slide rail 17 to achieve horizontal guidance of the drying kiln door. One end of the spring 19 is fixed to the inner wall of the lifting frame 1, and the other end is connected to one side of the slider 20, which plays a balancing and buffering role. The thin rod 4 forms a sliding connection with the sleeve 3 on the outside and is fixed in the middle of the protective plate 22 to ensure that it plays a buffering role. The sponge brush 15 is also slidably connected to one side of the slide rail 17, which further enhances the lubrication effect of the drying kiln door.

[0038] Working principle: the operator matches the rotating hook 11 with the hook on the drying kiln door, and then starts the internal power supply of the screw lifter 2, driving the hook 5 to move downward, and then driving the rope 6 to move downward, and then pulling the tripod 8, so that the rotating rod 9 rotates, and then the fixed plate 10 rotates, thereby driving the rotating hook 11 to rotate, and lift the drying kiln door from the ground until it contacts the protective plate 22, and continues to lift it. At this time, the drying kiln door squeezes the protective plate 22, and then the connecting rod 21 rotates, so that the slider 20 moves relatively on the slide bar 18, and then squeezes the spring 2 19 until the drying kiln door and the protective plate 22 are tightly fitted. At this time, the water pump 13 is driven to input the lubricating oil in the lubrication box 12 into the sponge brush 15 through the pipe 14. At this time, pushing the drying kiln door can make it move horizontally along the slide rail 17, and lubricate the slide rail 17 at the same time.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
