[0002] The platform frame of the boiler convection section is a structural device that provides support for the equipment and pipelines of the boiler convection section and facilitates maintenance and repair work. It is made of steel profiles and steel pipes and includes vertical supports, horizontal beams and platform plates.

[0003] The platform frame used in the boiler convection section is a key component for ensuring stable boiler operation and convenient maintenance. It is mainly constructed of sturdy steel sections and steel pipes, and has vertical supports, horizontal beams, and a platform slab. The vertical supports are rooted at the bottom of the boiler, bearing the weight of the entire platform frame and transferring gravity to the boiler foundation. In the past, boiler frames were simple frames constructed with steel bars and steel pipes. Now, the platform frame used in the boiler convection section improves the overall safety of the frame. However, the top of the existing platform frame used in the boiler convection section is a support structure composed of steel frames. This type of frame top cannot effectively provide shelter for the boiler top when it rains, causing rainwater to fall into the boiler. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a platform frame for the convection section of a boiler, aiming to improve the problem that the top of the existing frame cannot effectively shield the top of the boiler when it rains, causing rainwater to fall into the boiler.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a platform frame for a boiler convection section, comprising a platform frame, a motor fixedly connected to the right front end of the top of the platform frame, rotating rods rotatably connected to the front and rear sides of the top of the platform frame, the output end of the motor fixedly connected to the rotating rod on the right side, a drive sprocket fixedly connected to the front and rear ends of the outer wall of the rotating rod on the right side, a driven sprocket fixedly connected to the front and rear ends of the outer wall of the rotating rod on the left side, two drive sprockets being connected to the corresponding driven sprockets via chains, a waterproof cloth fixedly connected to the outer wall of the rotating rod on the left side, a connecting rod fixedly connected to the end of the waterproof cloth, and multiple splicing and expansion mechanisms equidistantly installed on the front and rear sides of the platform frame, the multiple splicing and expansion mechanisms being used to splice and expand the platform frame for the boiler convection section.

[0006] As a further description of the above technical solution:

[0007] The splicing and expansion mechanism includes buckles, with the rear ends of multiple buckles being fixedly connected at equal intervals to the front center of the platform frame. The left and right sides of the multiple buckles are slidably connected to fixing buckles, and the adjacent sides of the multiple fixing buckles are fixedly connected to springs. The middle of the adjacent sides of the multiple fixing buckles is fixedly connected to steel wires, and the ends of the multiple steel wires are fixedly connected to pull rods. The rear side of the platform frame has multiple slots at equal intervals.

[0008] As a further description of the above technical solution:

[0009] A stabilizing frame is fixedly connected to the bottom of the motor, and screws are threaded to the left and right sides, front and rear ends of the stabilizing frame.

[0010] As a further description of the above technical solution:

[0011] Each of the multiple buckles has a plurality of fixed rods rotatably connected at equal intervals on its inner center, and each of the multiple fixed rods has a pulley fixedly connected to its outer wall.

[0012] As a further description of the above technical solution:

[0013] Each of the multiple pull rods has a rubber sleeve fixedly connected to its outer wall, and each of the multiple rubber sleeves has anti-slip texture on its outer wall.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the power provided by the motor drives the rotation of the right rotating rod, thereby driving the drive sprocket fixed on it to rotate synchronously. At this time, the drive sprocket drives the driven sprocket and the right rotating rod to rotate synchronously through the chain, thereby driving the connecting rod to move to the right through the chain, so as to unfold the waterproof cloth rolled up outside the right rotating rod, thereby achieving the effect of shielding the top of the platform frame used for the convection section of the boiler from rain and snow.

[0022] 2. In this utility model, after pulling, the pull rod on the platform frame is pulled back into the buckle by the steel wire. Then the buckle is inserted into the slot behind the original platform frame. Then the pull rod is released.

[0031] 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.

[0032] Reference Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a platform frame for a boiler convection section, comprising a platform frame 1. A motor 3 is fixedly connected to the right front end of the top of the platform frame 1. Rotating rods 4 are rotatably connected to both the front and rear sides of the top of the platform frame 1. The motor 3 drives the rotating rods 4 to rotate. The output end of the motor 3 is fixedly connected to the right rotating rod 4. A drive sprocket 5 is fixedly connected to the front and rear ends of the outer wall of the right rotating rod 4. A driven sprocket 6 is fixedly connected to the front and rear ends of the outer wall of the left rotating rod 4. The two drive sprockets 5 are connected to the corresponding driven sprockets 6 via a chain 7. The driving sprocket 5 drives the driven sprocket 6 to rotate synchronously via the chain 7. A waterproof cloth 8 is fixedly connected to the outer wall of the left rotating rod 4. A connecting rod 9 is fixedly connected to the end of the waterproof cloth 8. The connecting rod 9 is used to unfold the waterproof cloth 8. Multiple splicing and expansion mechanisms 2 are installed at equal intervals on the front and rear sides of the platform frame 1. The multiple splicing and expansion mechanisms 2 are used to splice and expand the platform frame for the boiler convection section. A stabilizing frame 10 is fixedly connected to the bottom of the motor 3. Screws 11 are threadedly connected to the front and rear ends of the left and right sides of the stabilizing frame 10. Screws 11 are used to fix the stabilizing frame 10.

[0033] Specifically, the power provided by the motor 3 drives the rotation of the right rotating rod 4, which in turn drives the drive sprocket 5 fixed on it to rotate synchronously. At this time, the drive sprocket 5 drives the driven sprocket 6 and the right rotating rod 4 to rotate synchronously through the chain 7, thereby driving the connecting rod 9 to move to the right through the chain 7, so as to unfold the waterproof cloth 8 rolled up outside the right rotating rod 4. The stabilizing frame 10, which is fixed by screw 11, can improve the stability of the motor 3.

[0034] Reference Figure 5 and Figure 6 The splicing extension mechanism 2 includes buckles 201. The rear ends of multiple buckles 201 are equidistantly fixedly connected to the front center of the platform frame 1. Fixing buckles 202 are slidably connected to the left and right sides of each buckle 201. Springs 203 are fixedly connected to adjacent sides of each fixing buckle 202, and the springs 203 are used to push the fixing buckles 202. Steel wires 204 are fixedly connected to the center of adjacent sides of each fixing buckle 202. Pull rods 205 are fixedly connected to the ends of each steel wire 204. The pull rods 205... The steel wire 204 pulls the fixing buckle 202. Multiple slots 206 are equidistantly provided on the rear side of the platform frame 1. The slots 206 are used to accommodate the buckles 201. Multiple fixing rods 12 are equidistantly rotatably connected to the inner center of the multiple buckles 201. Pulleys 13 are fixedly connected to the outer wall of the multiple fixing rods 12. The fixing rods 12 are used to fix the pulleys 13. Rubber sleeves 14 are fixedly connected to the outer wall of the multiple pull rods 205. Anti-slip textures 15 are provided on the outer wall of the multiple rubber sleeves 14. The anti-slip textures 15 are used to lift the rubber sleeves 14.

[0035] Specifically, after pulling the lever 205 on the platform frame 1, the steel wire 204 moves backward within the buckle 201, thereby pulling the fixing buckle 202 back into the buckle 201 through the steel wire 204. Then, the buckle 201 is inserted into the slot 206 behind the original platform frame 1. After releasing the lever 205, multiple springs 203 will push out the corresponding fixing buckles 202, thereby fixing the two platform frames 1. The pulley 13 fixed by the fixing rod 12 can improve the smoothness of the steel wire 204. The rubber sleeve 14 fixed outside the lever 205 improves its grip through the anti-slip texture 15.

[0036] Reference Figure 1 A sunshade 16 is installed on the top left side of the platform frame 1. Screws 17 are threaded to the top front and rear sides and left and right ends of the sunshade 16. Screws 17 are used to fix the sunshade 16. Multiple X-shaped frames 18 are installed at equal intervals on the lower middle part of the front and rear sides of the platform frame 1. Screws 19 are threaded to the four corners of the multiple X-shaped frames 18. Screws 19 are used to fix the X-shaped frames 18. Guardrails 20 are fixedly connected to the middle of the front and rear sides of the platform frame 1. A ladder 21 is fixedly connected to the middle of the right side of the platform frame 1. The ladder 21 facilitates access to the platform.

[0037] Specifically, the sunshade 16, which is fixed by screw 2 17, can block sunlight for the rainproof cloth; the X-shaped frame 18, which is fixed by screw 3 19, can improve the stability of the platform frame used for the boiler convection section; the guardrail 20, which is fixed on the platform frame 1, can provide protection for the staff; and the platform frame used for the boiler convection section can be reached by climbing ladder 21.

[0038] Working principle: When the platform frame used for the boiler convection section encounters rain or snow, the motor 3 installed on the platform frame 1 is started first. The power provided by the motor 3 drives the rotation of the right rotating rod 4, which in turn drives the drive sprocket 5 fixed on it to rotate synchronously. At this time, the drive sprocket 5 drives the driven sprocket 6 and the right rotating rod 4 to rotate synchronously through the chain 7. This drives the connecting rod 9 to move to the right through the chain 7, thereby unfolding the waterproof cloth 8 rolled up outside the right rotating rod 4, thus achieving the effect of shielding the top of the platform frame used for the boiler convection section from rain and snow.

[0039] When expanding the platform frame used for the boiler convection section in the later stage, first pull the tie rod 205 on the newly installed platform frame 1, thereby driving the steel wire 204 to move backward within the buckle 201. This causes the fixing buckle 202 to retract into the buckle 201 through the steel wire 204. Then, the buckle 201 is inserted into the slot 206 behind the original platform frame 1. After that, the tie rod 205 is released. At this time, multiple springs 203 will push out the corresponding fixing buckles 202, thereby fixing the two platform frames 1. This achieves the splicing and expansion effect of the platform frame used for the boiler convection section.

[0040] 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.
