[0002] During the inspection and replacement of the water-cooled wall or refractory lining in a metallurgical blast furnace, or similar equipment such as large chimneys and vertical furnaces, or during the inspection and maintenance operations between two tall structures, it is necessary to remove the top components of the equipment, and then the operating personnel must first go down to a certain height position in the furnace where the inspection and maintenance work is required, suspend in mid-air in the furnace, drill holes in the refractory bricks, set positioning holes, and then set positioning holes for the walkway platform at that height to carry out dangerous operations at height; use the positioning holes to manually build a large-scale manual operation walkway or platform, and there are dangerous sources of injury accidents such as object strikes, falls from heights and mechanical injuries during the construction process, and the maintenance equipment cannot be replaced quickly, which reduces the maintenance efficiency of the equipment.

[0003] There are also many different ways to achieve the above purpose in the prior art. For example, in the patent with application number 201710146254.8, it discloses an automatic positioning mechanical arm bridge device and a positioning method for vertical furnace maintenance, wherein the automatic positioning mechanical arm bridge device includes a box-type body, a mechanical arm platform, a propeller, an electric push rod, an electric self-tapping rotary head, and an electric control box; the box-type body is a polygonal regular prism frame structure composed of metal steel, and mechanical arm platforms that cooperate with each other are arranged on both sides symmetrically with the center line of the box-type body, the lower part of the mechanical arm platform is movably hinged with a support fixed on the bottom frame of the box-type body, the upper part of the mechanical arm platform is movably hinged with the front end of the propeller push rod, and the rear end of the propeller push rod is movably hinged with the box-type body frame, and the mechanical arm platforms on both sides are pushed by the propeller, unfolded from the contracted state, and cooperated with each other to form a horizontal bridge platform; the front end of the mechanical arm platform is symmetrically provided with an electric push rod for support inside, and symmetrically provided with an electric self-tapping rotary head outside. This device can realize the automatic positioning, installation and removal of the bridge device, completely eliminate the safety hazards of the prior art, and ensure environmental clean construction.

[0063] In order to solve the problem that the top of the equipment needs to be dismantled when performing in-furnace maintenance on equipment such as a vertical furnace, and the fixed manned maintenance platform will damage the inner wall of the equipment, a vertical furnace rapid maintenance device is proposed in this application. Figure 1 This is a front view of the quick maintenance device for a vertical furnace in accordance with an embodiment of the present invention and the vertical furnace in cooperation with each other during maintenance in the furnace. Figure 2 for Figure 1 The top view at 1-1 in the middle. Figure 3 for Figure 1 The side view at 2-2 in the figure is as follows: Figures 1 to 3 As shown, the quick maintenance device for the vertical furnace comprises: a platform mechanism 02, the platform mechanism 02 comprises at least one platform surface 021, the platform surface 021 has a notch 022, the notch 022 is used to accommodate the vertical furnace 01, so that the vertical furnace 01 can pass through the platform surface 021; a beam conveying mechanism 04 installed on the platform surface 021; a horizontal beam 06 installed on the beam conveying mechanism 04, and the beam conveying mechanism 04 can limit the vertical movement of the beam 06. The invention relates to a manned maintenance platform 07, wherein the manned maintenance platform 07 is configured to move the crossbeam 06 in the extending direction of the crossbeam 06, so that the crossbeam 06 can extend into the vertical furnace 01 from the first opening 011 of the side wall of the vertical furnace 01; and a manned maintenance platform 07, wherein the manned maintenance platform 07 can enter into the vertical furnace 01 through the second opening 012 of the side wall of the vertical furnace 01, and then can be hoisted on the crossbeam 06. In the vertical furnace 01, the manned maintenance platform 07 can be raised and lowered in the vertical direction.

[0064] like Figure 1 and Figure 2 As shown, the platform mechanism 02 can be set up in the circumferential direction of the vertical furnace 01. The platform mechanism 02 can be built with a detachable structure, so that the platform mechanism 02 can be built when maintenance is required. After the maintenance is completed, the platform mechanism 02 can be easily dismantled, and the materials used to build the platform mechanism 02 can be recycled repeatedly. The platform mechanism 02 can include at least one platform surface 021, and the platform surface 021 has a notch 022. The notch 022 is used to accommodate the vertical furnace 01 so that the vertical furnace 01 can pass through the platform surface 021. The notch 022 can be a complete closed notch 022 or a semi-open notch 022. The platform surface 021 where the notch 022 is located needs to at least cover the area where the first opening 011 and the second opening 012 are located on the side wall of the vertical furnace 01.

[0065] like Figures 1 to 3 As shown, the platform surface 021 can be multi-layered, and upper and lower ladders 03 can be installed between adjacent platform surfaces 021, so that the operator can reach the platform surface 021 where the beam conveying mechanism 04 is located layer by layer through the ladder 03 from the ground, and it is also convenient for the operator to carry maintenance materials or equipment to the platform surface 021 where the beam conveying mechanism 04 is located.

[0066] like Figure 1As shown, a first opening 011 that can be opened and closed is provided on the side wall of the vertical furnace 01, and the first opening 011 can be located above the location inside the vertical furnace 01 that needs to be repaired. There can be one or two first openings 011. When there are two first openings 011, the two first openings 011 are respectively located on opposite side walls of the vertical furnace 01, so that the crossbeam 06 can pass through the two first openings 011 in the horizontal direction. As a feasible method, Figure 4 for Figure 1 The structural diagram of the first opening at 3-3 is as follows: Figure 4 As shown, the first opening 011 of the side wall of the vertical furnace 01 is a flange opening, and the first opening 011 can be sealed by a flange sealing cover, so that the sealing can be ensured and the first opening 011 can be opened and closed. The size of the first opening 011 only needs to be sufficient for the crossbeam 06 to pass through.

[0067] like Figure 1 As shown, a second opening 012 that can be opened and closed is provided on the side wall of the vertical furnace 01, and the first opening 011 can be located slightly below the first opening 011. The size of the second opening 012 is larger than the size of the first opening 011. As a feasible method, Figure 5 for Figure 1 The structural diagram of the second opening at 4-4 is as follows: Figure 5 As shown, the second opening 012 of the side wall of the vertical furnace 01 is a flange opening, and the second opening 012 can be sealed by a flange sealing cover, so that the sealing can be ensured and the second opening 012 can be opened and closed. The size of the second opening 012 needs to be sufficient for the manned maintenance platform 07 to enter the vertical furnace 01.

[0068] like Figure 1 and Figure 2 As shown, the beam conveying mechanism 04 is installed on the platform surface 021. The beam conveying mechanism 04 is fixedly connected and installed with the platform surface 021. The height of the platform surface 021 on which the beam conveying mechanism 04 is installed corresponds to the height of the second opening 012 that can be opened on the side wall of the vertical furnace 01. The beam 06 is installed on the beam conveying mechanism 04 and is arranged in the horizontal direction. The beam conveying mechanism 04 needs to limit the beam 06 in the vertical direction to prevent the beam 06 from tilting and tilting. In addition, the beam conveying mechanism 04 needs to be able to drive the beam 06 to move in the extension direction of the beam 06, so that the beam 06 can extend from the first opening 011 that can be opened on the side wall of the vertical furnace into the vertical furnace 01.

[0069] As feasible, Figure 1 and Figure 2As shown, the beam conveying mechanism 04 may include: a plurality of beam conveying sub-mechanisms 041 arranged along a first straight line, the first straight line passing through the first opening 011 of the side wall of the vertical furnace 01. Each beam conveying sub-mechanism 041 may include: a base 0413; at least one first roller 0411 and at least one second roller 0412 installed on the base 0413, the first roller 0411 and the second roller 0412 are distributed up and down, the beam 06 passes between the first roller 0411 and the second roller 0412, the first roller 0411 and the second roller 0412 can respectively abut against the upper side wall and the lower side wall of the beam 06, so as to limit the position of the beam 06 in the vertical direction. One of the first roller 0411 and the second roller 0412 is a driving wheel; a driving unit, the driving unit is used to drive the driving wheel to rotate, so that the driving wheel drives the beam 06 to move in the extension direction of the beam 06. A beam conveying mechanism electric control box 05 may also be installed on the platform surface 021 , and the operating state of the driving unit is controlled by the beam conveying mechanism electric control box 05 , thereby controlling the beam 06 to extend into the first opening 011 or to go out of the vertical furnace 01 from the first opening 011 .

[0070] The other of the first roller 0411 and the second roller 0412 is a driven wheel. Furthermore, the base 0413 has a track groove extending in the vertical direction, the shaft of the driven wheel is installed in the track groove, and the driven wheel can move up and down in the track groove. In order to make the crossbeam 06 always close to the driving wheel, so that the driving wheel can drive the crossbeam 06 to move through the friction force of the contact surface, as feasible, the crossbeam conveying sub-mechanism 041 may include: an elastic unit, the elastic unit is arranged between the driven wheel and the base 0413, the elastic unit makes the driven wheel have a tendency to move in the direction of the driving wheel, so that the driven wheel can always be close to the crossbeam 06.

[0071] like Figure 1 and Figure 2As shown, the manned maintenance platform 07 can enter the vertical furnace 01 through the second opening 012 of the side wall of the vertical furnace 01, and is hoisted on the crossbeam 06; in the vertical furnace 01, the manned maintenance platform 07 can be raised and lowered in the vertical direction, so that the operator can repair different positions of the inner side wall of the vertical furnace 01. The manned maintenance platform 07 can be connected to the crossbeam 06 through a hand chain hoist 08 and a chain. The manned maintenance platform 07 in the vertical furnace 01 is operated by a special hand chain hoist 08, which avoids the use contradiction caused by sharing the hoisting hoist in the workshop with other equipment during the maintenance of the vertical furnace 01, thereby improving the maintenance efficiency of the vertical furnace 01. The hand chain hoist 08 can be a small hand chain hoist, which avoids the collision of a large electric hoist with the refractory material in the furnace and damage to the furnace body when operating in the vertical furnace 01, and also avoids the possible harm caused by the electric equipment as a dangerous source in a confined space.

[0072] A pulley may be installed at the bottom of the manned maintenance platform 07 to facilitate the movement of the manned maintenance platform 07 on the platform surface 021, thereby improving the efficiency of the equipment rapid maintenance preparation work.

[0073] Since the manned maintenance platform 07 needs to enter the vertical furnace 01 through the second opening 012 of the side wall of the vertical furnace 01, in order to reduce the size of the second opening 012 as much as possible and reduce the heat loss during the operation of the vertical furnace 01, it is feasible that the length of the manned maintenance platform 07 in the vertical direction can be extended. When the manned maintenance platform 07 needs to pass through the second opening 012 of the side wall of the vertical furnace 01, the length of the manned maintenance platform 07 in the vertical direction is contracted to reduce its vertical size. After the manned maintenance platform 07 enters the vertical furnace 01, the length of the manned maintenance platform 07 in the vertical direction is extended to restore to the normal manned state.

[0074] In a possible implementation, Figures 6 to 9As shown, the manned maintenance platform may include: a base frame 2, the base frame 2 includes a base 22 and a first side frame 21 arranged on the base 22, the first side frame 21 includes a plurality of side columns arranged on the base 22; a suspension frame 1, the suspension frame 1 includes a suspension ceiling and a second side frame 101 connected to the suspension ceiling and capable of telescopic movement relative to the first side frame 21 in the height direction; a height adjustment structure, the height adjustment structure is arranged between the base frame 2 and the suspension frame 1, the height adjustment mechanism includes: a first matching member fixed in the first side frame 21, a second matching member fixed in the second side frame 101, and a height adjustment mechanism for driving the first matching member A height operating member 5 that moves relative to the second matching member, and when the height operating member 5 is operated, the relative height position of the base frame 2 and the suspension frame 1 can be adjusted; an expansion frame 9, the expansion frame 9 is movably connected to the base frame 2, and the expansion frame 9 can move relative to the base frame 2 in the horizontal direction; the expansion frame 9 has a working position extending out of the base frame 2 and a non-working position received in the base frame 2; a circumferential rotation adjusting portion, the circumferential rotation adjusting portion is arranged on the expansion frame 9, and when the expansion frame 9 is in the working position, the circumferential rotation adjusting portion can contact the vertical furnace to drive the manned maintenance platform to rotate circumferentially.

[0075] The manned maintenance platform provided in the implementation mode of the present application can utilize a height adjustment structure to adjust the relative height position of the base frame 2 and the suspension frame 1 at a set hoisting height, thereby realizing the adjustment of the manned maintenance platform in the height direction. At the same time, by setting an expansion frame 9 to expand the maintenance diameter and by using a circumferential rotation adjustment part to realize the rotation operation of the entire manned maintenance platform in the circumferential direction, the operator can flexibly adjust the spatial position of the entire manned maintenance platform according to operational needs, thereby greatly improving the efficiency of maintenance operations.

[0076] like Figure 6 and Figure 7 As shown, the manned maintenance platform mainly includes: a base frame 2, a suspension frame 1, a height adjustment mechanism, an expansion frame 9 and a circumferential rotation adjustment part.

[0077] like Fig.10 As shown, the base frame 2 may include a base 22 and a first side frame 21 disposed on the base 22, and the first side frame 21 may include a plurality of side columns disposed on the base 22 and spaced apart. Specifically, the base frame 2 may be in a square or rectangular shape, and of course, the base frame 2 may also be in a circular or other regular or irregular shape. In the embodiments of the present application, the base frame 2 is mainly described by taking a square structure as an example.

[0078] The base 22 may include a frame and a bottom wall on the frame. The frame may be square or rectangular, and a side column may be provided at each of the four corners of the frame. At least one accommodating cavity may be provided in the base 22, and the size and structure of the accommodating cavity may be compatible with the size and structure of the expansion frame 9.

[0079] like Figure 7 As shown, in this embodiment, the expansion frame 9 can be matched with the base frame 2 in a movable connection. By setting up the expansion platform, maintenance personnel can quickly reach the maintenance position without moving the manned maintenance platform itself, thereby improving maintenance efficiency.

[0080] Specifically, a guiding mechanism may be provided between the expansion frame 9 and the base 22. The guiding mechanism may include a matching mechanism of a slide rail and a slide groove. For example, a slide rail is provided on one of the expansion frame 9 and the base frame 2, and a slide groove is provided on the other of the expansion frame 9 and the base frame 2. When it is necessary to open the expansion frame 9, a force may be applied to the expansion frame 9, and through the guiding mechanism, the expansion frame 9 can be moved to a predetermined position in the horizontal direction relative to the base frame 2, so that the expansion frame 9 is switched from a non-working position to a working position. When the maintenance is completed, a reverse force may be applied to the expansion frame 9, and through the guiding mechanism, the expansion frame 9 is moved in the horizontal direction toward the direction close to the base frame 2, so that the expansion frame 9 is switched from a working position to a non-working position.

[0081] In this embodiment, the number of the expansion frames 9 may be one or more. Specifically, the number of the expansion frames 9 may vary according to different actual application scenarios of the manned maintenance platform.

[0082] In some embodiments, there are multiple expansion frames 9 , and the base 22 is provided with multiple accommodating cavities matching the expansion frames 9 at intervals along the height direction. The multiple expansion frames 9 move in different directions relative to the base frame 2 .

[0083] In this embodiment, when the manned maintenance platform is used in a vertical furnace with a larger cross-section, it can be provided with a plurality of expansion frames 9. Taking the number of the expansion frames 9 as two (respectively the first expansion frame and the second expansion frame), taking the overall outline of the base frame 2 as an example, the base frame 2 has a first side and a second side relative to each other, and a third side and a fourth side relative to each other. A first accommodating cavity for accommodating the first expansion frame and a second accommodating cavity for accommodating the second expansion frame can be provided in the base 22. The first accommodating cavity and the second accommodating cavity are arranged in sequence at intervals along the height direction. In the horizontal direction, the first accommodating cavity has a first opening near the first side, and the second accommodating cavity has a second opening near the second side. The cross-sectional structure of the first opening is adapted to the end face of the first expansion frame; the cross-sectional structure of the second opening is adapted to the end face of the second expansion frame. When it is needed, maintenance personnel can move the first expansion frame and the second expansion frame in opposite directions respectively, so that the maintenance diameter of the manned maintenance platform is expanded from the size of the original base frame 2 to the sum of the size of the base frame 2 and the size of the first expansion frame and the second expansion frame, and the horizontal size of the manned maintenance platform can reach the maximum.

[0084] like Fig.13 and Fig.14 As shown, in some embodiments, in order to ensure that the expansion frame 9 can be fixed relative to the base frame 2 after reaching the working position, thereby ensuring the safety of maintenance operators, the manned maintenance platform can also include an expansion positioner 10, and the expansion positioner 10 is used to limit the expansion frame 9 relative to the base frame 2 when the expansion frame 9 extends out of the base frame 2 and reaches the working position.

[0085] Specifically, the expansion positioner 10 may include: an adjustment rod fixed on the base frame 2, an expansion operating part arranged at one end of the adjustment rod, and a supporting part 16 arranged at the other end of the adjustment rod. By adjusting the expansion operating part, the supporting part 16 can be close to or away from the expansion frame 9.

[0086] The adjusting rod may be in the form of a screw 15, the outer surface of which is provided with an external thread; the base frame 2 is provided with an internal thread hole that matches the external thread of the screw 15. The expansion operation portion may be specifically an operating handle 17 provided on one side of the base frame 2. When the operating handle 17 is rotated in one direction (e.g., clockwise), the screw 15 can drive the abutment portion 16 to approach the expansion frame 9, so that the abutment portion 16 can contact the expansion frame 9, thereby constraining the expansion frame 9 from moving relative to the base frame 2. When the operating handle 17 is rotated in the opposite direction (e.g., counterclockwise), the screw 15 can drive the abutment portion 16 away from the expansion frame 9, and the abutment portion 16 is out of contact with the expansion frame 9, so that the expansion frame 9 can be accommodated in the base frame 2.

[0087] When the expansion frame 9 moves in the first direction relative to the base frame 2, the adjustment rod moves in the second direction relative to the expansion frame 9, and the second direction can be perpendicular to the first direction. The number of the expansion positioners 10 can be two, and the two expansion positioners 10 can be distributed at intervals on both sides of the base frame 2 along the second direction.

[0088] The abutting portion 16 may be an elastic limiting block.

[0089] For example, the abutting portion 16 may be a rubber stopper with a certain surface area. The rubber stopper utilizes its own elastic deformation capability to not only ensure a better abutting force, but also ensure that the surface of the position where the rubber stopper contacts will not be damaged.

[0090] In this embodiment, the circumferential rotation adjustment part can be specifically in the form of a universal wheel 11, and the universal wheel 11 can be arranged on the same side where the opening is arranged on the base 22 of the expansion frame 9 and the base frame 2. When the expansion frame 9 is in the working position, the universal wheel 11 can be extended along with the expansion frame 9, and when the universal wheel 11 contacts the vertical furnace, the operator applies torque to drive the entire manned maintenance platform to rotate in the circumferential direction, thereby realizing 360° maintenance angle adjustment in the circumferential direction.

[0091] In an embodiment of the present application, by providing a height adjustment structure between the base frame 2 and the suspension frame 1, the relative height position of the base frame 2 and the suspension frame 1 can be adjusted, thereby adjusting the height direction of the manned maintenance platform according to the needs of the maintenance operator.

[0092] Please refer to Figure 7 , Figure 8 and Fig. 9The height adjustment mechanism may include: a first matching piece fixed in the first side frame 21, a second matching piece fixed in the second side frame 101, and a height operating piece 5 for driving the first matching piece and the second matching piece to move relative to each other.

[0093] In this embodiment, the first matching piece and the second matching piece can be specifically in the form of a combination of a worm wheel 3 and a worm. Of course, the specific form of the first matching piece and the second matching piece can also be other combination forms that can achieve height direction adjustment. In the embodiment of the present application, the above-mentioned worm wheel 3 and worm are mainly used as examples for illustration.

[0094] In one embodiment, the first mating part may include a worm wheel 3, and the second mating part may include a worm assembly 4, wherein the worm assembly 4 includes a first worm 41 and a second worm 42 arranged in parallel at a predetermined distance; the worm wheel 3 is arranged between the first worm 41 and the second worm 42, and is meshed with the first worm 41 and the second worm 42 respectively.

[0095] Among them, a travel groove 8 for facilitating the movement of the worm wheel 3 may be provided on the second side frame 101 of the suspension frame 1 along the height direction. Specifically, a center rod is provided at the center of the worm wheel 3, and the center rod is inserted into the travel groove 8. Both ends of the center rod may be provided with a height operating member 5 respectively. The operator can drive the worm wheel 3 to rotate by operating the height operating member 5, and then drive the worm wheel 3 to move relative to the worm, thereby realizing the height adjustment of the base frame 2 relative to the suspension frame 1.

[0096] like Figure 7 As shown, the suspended ceiling is provided with a plurality of lifting ears 102, and the plurality of lifting ears 102 are located at the position where the suspended ceiling is connected to the second side frame 101. For example, when the suspended ceiling is square as a whole, each corner of the suspended ceiling can be provided with a lifting ear 102. When in use, the suspension device can be connected to the lifting ear 102, so that the suspension frame 1 can be reliably positioned. In the embodiment of the present application, the suspension operation is performed by the suspension frame 1, which avoids the interference caused by the lifting rope directly lifting the manned maintenance platform, thereby causing the problem of low efficiency of the maintenance operation.

[0097] Since there needs to be sufficient matching force between the suspension frame 1 and the base frame 2 so that they can reliably bear the sum of the gravity of the base frame 2, the maintenance operators and some necessary maintenance tools, a locking structure can be further set on the suspension frame 1 and the base frame 2 bracket to limit the movement of the base frame 2 relative to the suspension frame 1.

[0098] Please refer to Fig.10 and Fig.11Specifically, the second side frame 101 can be a hollow rectangular frame, the second side frame 101 has a first side wall and a second side wall relative to each other, and a third side wall and a fourth side wall relative to each other, the first worm 41 is arranged close to the first side wall, and the second worm 42 is arranged close to the second side wall, and the third side wall and the fourth side wall are provided with a plurality of spaced-apart positioning grooves 7 along the height direction, and the manned maintenance platform also includes a height positioning device 6 adapted to the positioning groove 7, and the height positioning device 6 cooperates with the positioning groove 7 to limit the movement of the base frame 2 relative to the suspension frame 1.

[0099] Among them, the first matching piece is arranged at a position close to the top of the first side frame 21, the cross-section of the first side frame 21 is smaller than the cross-section of the second side frame 101, the first side frame 21 at least partially extends into the second side frame 101, the height stopper 6 includes a spring 14, and the two ends of the spring 14 are respectively provided with a first stop block 61 and a second stop block 62, the first stop block 61 and the second stop block 62 are inserted into the stop groove 7, at least part of the first stop block 61 protrudes from the third side wall, and at least part of the second stop block 62 protrudes from the fourth side wall, when the first stop block 61 and the second stop block 62 are applied with relative forces, the spring 14 can be compressed, the first stop block 61 and the second stop block 62 can be moved into the second side frame 101, and the base frame 2 and the suspension frame 1 can move relative to each other.

[0100] like Fig.12 As shown, in this embodiment, the limiting structure may include a structure in which a height stopper 6 and a stopper groove 7 cooperate. The height stopper 6 may be a stopper with a certain deformation capability. When the detection operator presses the first stopper block 61 and the second stopper block 62, the height stopper 6 may be retracted into the second side frame 101 to achieve unlocking. After unlocking, the base frame 2 and the suspension frame 1 may move relative to each other by a distance spaced by the stopper groove 7.

[0101] In one embodiment, a spacer 12 and a roller bearing 13 are respectively disposed at both ends of the first worm 41 and the second worm 42. The spacer 12 is annular, and the inner diameter of the spacer 12 is greater than or equal to the inner diameter of the roller bearing 13, and the outer diameter of the spacer 12 is less than or equal to the outer diameter of the roller bearing 13.

[0102] In this embodiment, a spacer 12 and a roller bearing 13 are provided at both ends of the first worm 41 and the second worm 42, and the size of the spacer 12 does not exceed the radial size of the roller bearing 13, that is, the projection of the roller bearing 13 toward the spacer 12 can cover the spacer 12, thereby ensuring that the characteristics of the roller bearing 13 can be utilized to inspect the wear of the worm on the suspension frame 1.

[0103] In one embodiment, the second side frame 101 of the suspension frame 1 is provided with a plurality of locking grooves 7 along the height direction, and the locking grooves 7 can be used to pass the safety rope 18 .

[0104] By setting a locking groove 7 along the height direction on the second side frame 101 of the suspension frame 1, a height-matched locking groove 7 can be selected according to the different height requirements of maintenance personnel to pass the safety rope 18, and the safety rope 18 is connected to the maintenance operator. The safety of the maintenance operator can be further improved by using the safety rope 18.

[0105] The present application also proposes a method for rapid maintenance of a shaft furnace, which can use a shaft furnace rapid maintenance device such as any of the shaft furnace rapid maintenance devices described above. The method for rapid maintenance of a shaft furnace can include:

[0106] A first opening 011 and a second opening 012 are formed on the side wall of the vertical furnace 01 so as to be openable and closable.

[0107] The beam conveying mechanism 04 is installed on the platform surface 021 at a height corresponding to the second opening 012 of the side wall of the vertical furnace 01, and the height of the beam conveying mechanism 04 is determined according to the height between the first opening 011 and the platform surface 021. In this way, it is ensured that the beam 06 installed on the beam conveying mechanism 04 can pass through the first opening 011 to the interior of the vertical furnace 01 when extended.

[0108] The first opening 011 is opened, and the beam 06 is driven to extend through the beam conveying mechanism 04 to pass through the first opening 011 so that part of the beam 06 extends into the vertical furnace 01 .

[0109] In this step, the driving unit is turned on and the direction of rotation of the driving unit is controlled, thereby driving the driving wheel to rotate, and the driving wheel then drives the cross beam 06 to move in the extension direction of the cross beam 06, and the cross beam 06 extends to pass through the first opening 011 so that part of the cross beam 06 extends into the vertical furnace 01. When the side wall of the vertical furnace 01 has two first openings 011, the cross beam 06 can extend into the vertical furnace 01 from one of the first openings 011 and then extend from the other first opening 011, so that the stability of the entire cross beam 06 is higher, and the other first opening 011 can be used to support the end of the cross beam 06 to a certain extent.

[0110] The second opening 012 is opened, and after the crossbeam 06 extends into the vertical furnace 01 , a manned maintenance platform 07 is inserted into the vertical furnace 01 through the second opening 012 and hoisted onto the crossbeam 06 .

[0111] In this step, the hand chain hoist 08 and the chain connected to the manned maintenance platform 07 can be installed on the crossbeam 06 through the second opening 012, and then the manned maintenance platform 07 can be sent into the vertical furnace 01 from the second opening 012. Then, the manned maintenance platform 07 can be lifted and moved in the vertical direction by the hand chain hoist 08. The operator can enter the vertical furnace 01 from the second opening 012 to the manned maintenance platform 07, and lift and move it in the vertical direction by the hand chain hoist 08, so as to complete the corresponding maintenance work.

[0112] After the use of the manned maintenance platform 07 is completed, that is, the operator completes the maintenance work in the vertical furnace 01, the manned maintenance platform 07 is moved out of the vertical furnace 01 through the second opening 012 to the platform surface 021, and separated from the beam 06, that is, the hand winch 08 and the chain are removed from the beam 06.

[0113] After the manned maintenance platform 07 is moved out of the vertical furnace 01 , the beam conveying mechanism 04 drives the beam 06 to withdraw from the first opening 011 to the outside of the vertical furnace 01 .

[0114] In this step, the driving unit is turned on to rotate in the reverse direction, thereby driving the driving wheel to rotate in the reverse direction, and the driving wheel then drives the beam 06 to move in the extension direction of the beam 06, so as to withdraw the beam 06 from the vertical furnace 01 through the first opening 011.

[0115] After the manned maintenance platform 07 is moved out of the vertical furnace 01, the second opening 012 is closed;

[0116] After the crossbeam 06 is withdrawn from the first opening 011 to the outside of the vertical furnace 01, the first opening 011 is closed, that is, the crossbeam conveying mechanism 04, the first opening 011 and the second opening 012 are all returned to the initial positions, and the subsequent normal operation of the vertical furnace 01 is not hindered.

[0117] This application may have the following advantages:

[0118] The present application allows installation of maintenance equipment without disassembling the main equipment of the vertical furnace (for example, removing the furnace top cover and placing the maintenance equipment in). By using the first opening 011 to pass the crossbeam near the top of the vertical furnace, the problems of installation accuracy and equipment sealing caused by repeated disassembly of the main equipment of the vertical furnace are avoided. At the same time, the construction workload of the maintenance is reduced, and the subsequent normal use of the main equipment of the vertical furnace is guaranteed.

[0119] The present application can quickly transport the beam used to hang the manned maintenance platform 07 to the designated position in the furnace by setting up an external beam conveying mechanism 04; if the maintenance in the vertical furnace is completed, the beam can also be quickly withdrawn to the initial position outside the furnace, further improving the work efficiency of installing maintenance equipment. The side wall of the vertical furnace has a second opening 012 that can be opened, and the manned maintenance platform 07 can be passed through the second opening 012 to enter the vertical furnace and be hung on the beam in the furnace.

[0120] Since the maintenance operation is performed inside the vertical furnace, the special hand chain hoist 08 in the vertical furnace is set to solve the equipment usage contradiction caused by the equipment in the workshop sharing a set of electric hoists, and also avoid the safety hazards that may be caused by the operation of electric equipment as a dangerous source in a confined space. In addition, the application can use a special small hand chain hoist to avoid the problem of a larger electric hoist colliding with the refractory material in the furnace and damaging the furnace body when operating in the vertical furnace.
