[0035] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0036] like Figure 1 and Figure 2As shown, the utility model provides a furnace pipe disassembly device, which is connected to multiple pairs of support components distributed in parallel and vertically on the machine frame, each pair of support components includes two support frames 1, and the two support frames 1 are distributed in parallel at intervals, and the furnace pipe disassembly device includes multiple mobile brackets 2, two auxiliary side brackets 3, a fixed rod 4, two first connecting bayonet holes 5, two second connecting bayonet holes 6, multiple slide rails, multiple pulleys and multiple fasteners, and each of the auxiliary side brackets 3 includes an adjusting rod 31, an auxiliary rod 32, a first connecting rod 33 and a second connecting rod 34;

[0038] One end of the two first connection bayonet holes 5 is respectively connected to the end of the other end of the two auxiliary rods 32, one end of the two second connection bayonet holes 6 is respectively connected to one side of the other end of the two first connection rods 33, and the other end of the two first connection bayonet holes 5 and the other end of the two second connection bayonet holes 6 are respectively rotatably connected to one end of the support frame 1 of two pairs of support assemblies through fasteners;

[0039] Both ends of the bottom surface of each movable bracket 2 are connected to a slide rail, and the top surface of each support frame 1 is fixed with two pulleys. Each movable bracket 2 is slidably connected with the two support frames 1 through the slide rail and the pulley.

[0040] Specifically, the number of mobile brackets 2 is the same as the number of support assemblies. The number of support assemblies on the machine frame of the utility model is five pairs, so the number of support brackets 1 is ten, the number of mobile brackets 2 is five, the number of slide rails is ten, and the number of pulleys is twenty.

[0041] Furthermore, in order to ensure the stability of the sliding of the movable bracket 2 on the support frame 1, at least two pulleys are installed on one support frame 1, and the specific number of installed pulleys can be changed according to actual conditions.

[0042] like Figure 3 and Figure 4 As shown, in a specific implementation mode, the furnace tube 8 is fixed to the machine frame by the mobile bracket 2. When replacing the furnace tube 8 located at the top layer of the machine frame, the staff manually pulls the mobile bracket 2 so that the two ends of the mobile bracket 2 slide along the two support frames 1 to the two auxiliary rods 32 of the two auxiliary side brackets 3, and the fork is raised by the forklift so that the top surface of the fork abuts against the bottom surface of the mobile bracket 2. Then the fixed rod 4 is removed, and the two auxiliary side brackets 3 are rotated outwards so that the bottom surface of the mobile bracket 2 is separated from the two auxiliary rods 32. At this time, the mobile bracket 2 is The frame 2 and the furnace tube 8 are completely placed on the fork, and the fork drives the movable bracket 2 and the furnace tube 8 to descend to complete the disassembly of the top-layer furnace tube 8; when replacing the furnace tube 8 located in the middle layer of the machine frame, the staff needs to adjust multiple fasteners to lower the connection position of the auxiliary rod 32, the first connecting rod 33 and the second connecting rod 34 on the adjusting rod 31, so that the auxiliary rod 32 can be connected to the support frame 1 of the middle layer through the first connecting bayonet 5, and the movable bracket 2 located in the middle layer can slide onto the auxiliary rod 32, thereby disassembling the furnace tube 8 of the middle layer.

[0043] When disassembling the furnace tube 8 located at the bottom layer of the machine frame in the utility model, the staff pulls the movable bracket 2 at the bottom layer so that the movable bracket 2 and the furnace tube 8 at the bottom layer can be directly placed on the fork of the forklift. There is no need to rotate the two auxiliary side brackets 3 or adjust the height of the connection position of the auxiliary rod 32 on the adjusting rod 31, and the disassembly of the furnace tube 8 at the bottom layer of the machine frame can be completed.

[0044] By detachably connecting the adjusting rod 31, the auxiliary rod 32, the first connecting rod 33 and the second connecting rod 34 in each auxiliary side bracket 3 through fasteners, the height of the connection position of the auxiliary rod 32 on the adjusting rod 31 can be adjusted to realize the disassembly of the furnace tube 8 located on the top layer or the middle layer of the machine frame, ensuring that each furnace tube 8 can be safely disassembled; the two auxiliary side brackets 3 are rotatably connected to one end of the multiple support frames 1 through fasteners, two first connecting bayonet sockets 5 and two second connecting bayonet sockets 6, and the two ends of the fixing rod 4 are respectively connected to the two adjusting rods 31 in the two auxiliary side brackets 3 through fasteners, so that the fixing rod 4 can rotatably The two auxiliary side brackets 3 are fixed to prevent the two auxiliary side brackets 3 from rotating when the mobile bracket 2 slides to the top surface of the auxiliary rod 32, so as to ensure that after the mobile bracket 2 and the furnace pipe 8 are placed on the fork, the auxiliary side brackets 3 are rotated to make the two ends of the mobile bracket 2 disengage from the two auxiliary rods 32; by connecting a slide rail to both ends of the bottom of each mobile bracket 2 and connecting two pulleys to the top surface of each support frame 1, a mobile bracket 2 can slide on the two support frames 1 in a pair of support assemblies, so that the furnace pipe 8 can remain stable during the disassembly process, and to a certain extent, it can avoid the furnace pipe 8 rolling and causing accidents.

[0045] Alternatively, if Figure 5 As shown, each of the mobile brackets 2 includes three rectangular tubes 21 and two short square tubes 22. The three rectangular tubes 21 are of equal length and placed in parallel. The two ends of the first rectangular tube 21 are respectively connected to one end of the two short square tubes 22, the two ends of the second rectangular tube 21 are respectively connected to the other end of the two short square tubes 22, and the two ends of the third rectangular tube 21 are respectively connected to the two opposite side surfaces of the two short square tubes 22.

[0046] Optionally, the distance between the first rectangular tube 21 and the third rectangular tube 21 is greater than the distance between the second rectangular tube 21 and the third rectangular tube 21 .

[0047] Specifically, the spacing between the first rectangular tube 21 and the third rectangular tube 21 is related to the diameter of the placed furnace tube 8. The spacing between the first rectangular tube 21 and the third rectangular tube 21 is smaller than the diameter of the furnace tube 8, but it is necessary to ensure that the furnace tube 8 can be clamped between the first rectangular tube 21 and the third rectangular tube 21.

[0048] When placing the furnace pipe 8, by clamping the furnace pipe 8 between the first rectangular tube 21 and the third rectangular tube 21, when the staff pulls the movable bracket 2, the furnace pipe 8 can be stable on the movable bracket 2 without rolling, thereby avoiding accidents.

[0049] Optionally, the auxiliary side bracket 3 also includes a third connecting rod 35, a fourth connecting rod 36, a fifth connecting rod 37 and two third connecting bayonet sockets 7, one end of the third connecting rod 35 is detachably connected to the other end of the first connecting rod 33 through a fastener, one end of the fourth connecting rod 36 is detachably connected to the other end of the third connecting rod 35 through a fastener, the other end of the fourth connecting rod 36 is detachably connected to the first side surface 311 of the adjusting rod 31 through a fastener and an adjustment hole, one end of the fifth connecting rod 37 is detachably connected to the other end of the third connecting rod 35 through a fastener, the other end of the fifth connecting rod 37 is detachably connected to the first side surface 311 of the adjusting rod 31 through a fastener and an adjustment hole, and the connection position of the other end of the fifth connecting rod 37 to the adjusting rod 31 is higher than the connection position of the other end of the fourth connecting rod 36 to the adjusting rod 31;

[0050] One end of the two third connection bayonet sockets 7 is respectively connected to one side of the other end of the two third connection rods 35, and the other end of the two third connection bayonet sockets 7 is rotatably connected to one end of the support frame 1 of one pair of support assemblies through fasteners.

[0051] When disassembling the upper layer of the machine frame, since the furnace pipe 8 is placed too high, by adding a third connecting rod 35, a fourth connecting rod 36, a fifth connecting rod 37 and two third connecting clips 7 to the auxiliary side bracket 3, when the mobile bracket 2 located at the top layer of the machine frame slides to the auxiliary side bracket 3, the supporting force provided by the auxiliary side bracket 3 for the mobile bracket 2 and the strength of the auxiliary side bracket 3 itself can be increased.

[0052] Preferably, when the auxiliary side bracket 3 includes an adjusting rod 31, an auxiliary rod 32, a first connecting rod 33, a second connecting rod 34, a third connecting rod 35, a fourth connecting rod 36, a fifth connecting rod 37 and two third connecting bayonet sockets 7, it is more suitable for disassembling the three furnace tubes 8 located on the first layer, the second layer and the third layer from top to bottom of the machine frame in the utility model, that is, the first connecting bayonet socket 5 is connected to one end of the support frame 1 of the first layer, the second connecting bayonet socket 6 is connected to one end of the support frame 1 of the second layer, and the third connecting bayonet socket 7 is connected to one end of the support frame 1 of the third layer, so as to disassemble the furnace tube 8 of the first layer; the first connecting bayonet socket 5 is connected to one end of the support frame 1 of the second layer, the second connecting bayonet socket 6 is connected to one end of the support frame 1 of the third layer, and the third connecting bayonet socket 7 is connected to one end of the support frame 1 of the fourth layer, so as to disassemble the furnace tube 8 of the second layer; the first connecting bayonet socket 5 is connected to one end of the support frame 1 of the third layer, the second connecting bayonet socket 6 is connected to one end of the support frame 1 of the fourth layer, and the third connecting bayonet socket 7 is connected to one end of the support frame 1 of the fifth layer, so as to disassemble the furnace tube 8 of the third layer.

[0053] When disassembling the furnace tube 8 of the fourth layer, disassemble the third connecting rod 35, the fourth connecting rod 36, the fifth connecting rod 37 and the two third connecting bayonet 7 in the auxiliary side bracket 3, so that the first connecting bayonet 5 in the auxiliary side bracket 3 is connected to one end of the support frame 1 of the fourth layer, and the second connecting bayonet 6 is connected to one end of the support frame 1 of the fifth layer.

[0054] When disassembling the furnace tube 8 at the bottom layer, there is no need to rotate the two auxiliary side brackets 3, nor to adjust the height of the connection position of the auxiliary rod 32 on the adjusting rod 31. The staff pulls the movable bracket 2 at the bottom layer so that the movable bracket 2 and the furnace tube 8 at the bottom layer can be directly placed on the fork of the forklift, thereby completing the disassembly of the furnace tube 8 at the bottom layer in the machine frame.

[0055] Alternatively, if Figures 6 to 8 As shown, the first connection bayonet 5, the second connection bayonet 6 and the third connection bayonet 7 are all short circular tubes; the lengths of the top surface, the bottom surface and the inner side surface of each of the first connection bayonet 5 are the same, and the length of the outer side surface of each of the first connection bayonet 5 is shorter than the lengths of the top surface, the bottom surface and the inner side surface; the lengths of the top surface and the bottom surface of each of the second connection bayonet 6 are the same, and the lengths of the two side surfaces of each of the second connection bayonet 6 are shorter than the lengths of the top surface and the bottom surface; the lengths of the top surface and the bottom surface of each of the third connection bayonet 7 are the same, and the lengths of the two side surfaces of each of the second connection bayonet 6 are shorter than the lengths of the top surface and the bottom surface;

[0056] One end of the top surface, one end of the bottom surface, one end of the outer side surface and one end of the inner side surface of each of the first connecting bayonet 5 are connected to the end of the other end of the auxiliary rod 32, and the other end of the top surface of each of the first connecting bayonet 5 is connected to one end of the support frame 1;

[0058] One end of the top surface, one end of the bottom surface, one end of the outer side surface and one end of the inner side surface of each of the third connecting bayonet 7 are connected to a side surface of the other end of the third connecting rod 35, and the other end of each of the third connecting bayonet 7 is connected to one end of the support frame 1 through a vertically inserted fastener.

[0059] In a specific embodiment, compared with the lengths of the top surface, bottom surface and inner surface of the first connection bayonet 5, the length of the outer surface of the first connection bayonet 5 is shorter, so that one end of the first connection bayonet 5 is a flush end and the other end is a notch end, so the flush end is connected to the end of one end of the auxiliary rod 32, and the notch end is sleeved on the outer periphery of one end of the support frame 1 and connected to one end of the support frame 1 through a vertically inserted fastener;

[0060] Compared with the length of the top and bottom surfaces of the second connection bayonet 6, the length of the two side surfaces of the second connection bayonet 6 is shorter, so that one end of the second connection bayonet 6 is a flush end and the other end is a notch end, so the flush end is connected to the end of the other end of the first connecting rod 33, and the notch end is sleeved on the periphery of one end of the support frame 1 and connected to one end of the support frame 1 through a horizontally inserted fastener;

[0061] Compared with the length of the top and bottom surfaces of the third connection bayonet 7, the length of the two side surfaces of the third connection bayonet 7 is shorter, so that one end of the third connection bayonet 7 is a flush end and the other end is a notch end, so the flush end is connected to the end of the other end of the second connection rod 34, and the notch end is sleeved on the periphery of one end of the support frame 1 and connected to one end of the support frame 1 through a horizontally inserted fastener;

[0062] When the two auxiliary side brackets 3 need to be rotated, first remove the fasteners vertically plugged into the two first connecting bayonet sockets 5, then remove the fixing rod 4, and finally the staff pushes the two auxiliary side brackets 3 so that the two auxiliary side brackets 3 can rotate with the fasteners horizontally plugged into the two second connecting bayonet sockets 6 and the two third connecting bayonet sockets 7 as the rotation axis.

[0063] Of course, the shape of the first connecting bayonet 5 can also be the same as the shape of the second connecting bayonet 6. If the shape of the first connecting bayonet 5 is the same as the shape of the second connecting bayonet 6, the connection method between the first connecting bayonet 5 and one end of the support frame 1 is the same as the connection method between the second connecting bayonet 6 and one end of the support frame 1.

[0064] Specifically, the fasteners in the present invention all adopt pins.

[0065] Optionally, the bottoms of the two adjusting rods 31 are respectively connected to a universal wheel.

[0066] By providing universal wheels, the two auxiliary side brackets 3 can rotate more smoothly.
