[0031] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0032] Reference Figures 1-6 As an embodiment of the present utility model, a fluidized bed furnace purging trolley is provided. The fluidized bed furnace purging trolley includes a mobile trolley body 1, and also includes mobile wheels 11 on both sides of the bottom of the two ends of the mobile trolley body 1 to facilitate moving the mobile trolley body 1 to the feeding port of the fluidized bed furnace, a swaying mechanism 2 set on one side of the top of the mobile trolley body 1, a pushing mechanism 3 set on the swaying mechanism 2, and a slide rail mechanism 6 set on the mobile trolley body 1.

[0033] The slide rail mechanism 6 includes a second slide rail 63 mounted on the top of one side of the mobile trolley body 1, a second slider 64 slidably connected to the surface of the slide rail mechanism 6, and a swaying mechanism 2 including a swaying support 21 mounted on one side of the second slider 64, an outer mounting cylinder 20 mounted on one side of the swaying support 21, a swaying shaft bearing 23 fixedly mounted on the top and bottom of the inner cavity of the outer mounting cylinder 20, a swaying shaft 24 fixedly sleeved inside the swaying shaft bearing 23, with both ends of the swaying shaft 24 extending to the outside of the outer mounting cylinder 20, a servo drive motor 22 mounted on the bottom of the outer mounting cylinder 20, with the output end of the servo drive motor 22 connected to the bottom end of the swaying shaft 24, and an upper mounting plate 29 fixedly mounted on the top of the swaying shaft 24.

[0034] A first slide rail 61 is installed on the top of the mobile trolley body 1 near the yaw mechanism 2. A first slider 62 is slidably connected to the top of the first slide rail 61. An L-shaped connecting plate 28 is fixedly installed on the top of the first slider 62. One side of the L-shaped connecting plate 28 is connected to one side of the yaw support 21. A second mounting base 52 is fixedly installed on the end of the L-shaped connecting plate 28 away from the yaw support 21. A left and right adjustment electric cylinder 5 is fixedly installed on the top end of the mobile trolley body 1. A connecting block 51 is fixedly installed on the output end of the left and right adjustment electric cylinder 5. The connecting block 51 and the second mounting base 52 are hinged to each other. By using the connection between the L-shaped connecting plate 28 and the push support 31, the left and right adjustment electric cylinder 5 can push the L-shaped connecting plate 28 to move, which can also make the yaw support 21 move synchronously, thereby driving the yaw mechanism 2 and the push mechanism 3 to move synchronously.

[0035] The pushing mechanism 3 includes a pushing support 31 mounted on the mounting top plate 29, two sets of nodding supports 25 fixedly mounted on one side of the top of the mounting top plate 29, a nodding shaft bearing 27 fixedly mounted at one end of the nodding support 25, the nodding shaft bearing 27 passing through the nodding support 25, a nodding shaft 26 fixedly sleeved inside the nodding shaft bearing 27, and two sets of hinged base plates 38 fixedly mounted at the bottom of the sway support 21, with the two sets of nodding supports 25 located between the two sets of hinged base plates 38. The two sets of hinged base plates 38 are close to each other and have rotation holes at one end. The two ends of the nodding shaft 26 extend into the rotation holes at one end of the two sets of hinged base plates 38.

[0036] The pushing mechanism 3 also includes an anti-rotation slot 302 opened on the top of the pushing support 31, a blowing pipe 33 slidably connected to the inside of the anti-rotation slot 302, and both ends of the blowing pipe 33 extending to the outside of the anti-rotation slot 302, and a blowing head 32 installed at one end of the blowing pipe 33. The blowing head 32 can be replaced with different lengths, and workers can sweep different areas by changing the blowing head 32.

[0037] Pushing side plates 303 are fixedly installed at both ends of the top of the pusher support 31. Two sets of pusher side plates 303 are mounted with gear shaft bearings 35 close to each other at one end, and the gear shaft bearings 35 pass through the purge pipe 33. A gear shaft 34 is fixedly sleeved inside the gear shaft bearings 35. A pusher gear 30 is fixedly sleeved on the surface of the gear shaft 34. A pusher rack 301 is fixedly installed on the top of the purge pipe 33, and the pusher rack 301 and the pusher gear 30 mesh with each other. A pusher motor 36 is fixedly installed on the two sets of pusher side plates 303 close to each other at one end, and the output end of the pusher motor 36 passes through one set of pusher side plates 303. A first synchronous gear 37 is fixedly sleeved on the output end of the pusher motor 36, and a second synchronous gear 39 is fixedly sleeved on one end of the surface of the gear shaft 34, and the second synchronous gear 39 and the first synchronous gear 37 mesh with each other. The anti-rotation slot 302 is used to ensure that the purge pipe 33 will not rotate during pushing.

[0038] A first mounting base 41 is fixedly installed on one side of the top end of the mounting plate 29. A connecting arm 42 is fixedly installed on one side of a set of push side plates 303. A nodding electric cylinder 4 is hinged to the top of the first mounting base 41. The output end of the nodding electric cylinder 4 and one end of the connecting arm 42 are hinged to each other. By setting the nodding electric cylinder 4, the first mounting base 41 at one end of the connecting arm 42 can perform a nodding operation.

[0039] During use, when the fluidized bed furnace needs cleaning, the worker pushes the mobile trolley body 1 to the fluidized bed furnace feeding port, and the purge pipe 33 introduces purge gas. By starting the servo drive motor 22 to rotate forward and backward, the oscillating shaft 24 rotates inside the mounting outer cylinder 20, and then the mounting top plate 29 on the top of the oscillating shaft 24 also rotates. Then the purge pipe 33 on the push support 31 swings left and right, and the purge head 32 blows out gas to automatically purge the purge area of ​​the fluidized bed furnace. At the same time, the push motor 36 is started to rotate forward and backward, driving the first synchronous gear 37 to rotate. Through the meshing of the first synchronous gear 37 and the second synchronous gear 39, the gear shaft 34 can be driven to rotate, and then the push gear 30 rotates forward and backward. The meshing of the push gear 30 and the push rack 301 drives the push rack 301 to move back and forth, and then the extension and retraction of the purge pipe 33 can be controlled.

[0040] Simultaneously, the nodding electric cylinder 4 can be activated, using its output to drive the connecting arm 42 to move up and down, causing the hinged base plate 38 on the push support 31 to move up and down on the surface of the nodding shaft 26. Then, the up and down angle of the blow pipe 33 on the push support 31 can be adjusted. Finally, the left and right adjustment electric cylinder 5 can be activated to move the first slider 62 and the second slide rail 63 on the first slide rail 61 and the second slider 64, thereby causing the sway support 21 to move left and right, and the blow pipe 33 on the push support 31 to also move left and right, increasing the blowing range. This achieves automatic blowing, allowing workers to only move the trolley body 1 and change the blow head 32 at the beginning, reducing their workload and keeping them away from the high-temperature furnace opening and splashes, thus ensuring greater safety.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
