TECHNICAL FIELD
[0001] The present application relates to the technical field of sintering furnace, in particular to a refractory spherical top cover integrated installation device and process. BACKGROUND
[0002] In the tungsten-molybdenum smelting industry, the hydrogen atmosphere medium-frequency induction sintering furnace as the core sintering equipment, the stability of its furnace body structure directly affects the product quality and production safety. At present, the mainstream medium-frequency induction sintering furnace on the market generally uses zirconia and alumina products for refractory material selection, and completes the furnace lining construction by dry masonry process. In the assembly process of the whole equipment, the prefabricated refractory material module needs to be accurately and neatly arranged according to the designed size, and after forming a complete furnace lining unit, it is hoisted to the inside of the furnace shell by a special hoisting device, and then calibrated and fixed horizontally and vertically to complete the integrated installation process.
[0003] Compared with the assembly of conventional furnace bodies, the installation of the top cover of a large circular sintering furnace faces more complex technical challenges. Such a cover is composed of multiple arc-shaped assembly pieces, which need to be hoisted to the specified position on the furnace top by large lifting equipment such as a tower crane or a truck crane. However, in the actual operation process, due to the certain height and volume of the assembly pieces, as well as the influence of factors such as airflow disturbance and uneven lifting cable tension during hoisting, irregular shaking is easily caused. This shaking not only makes it difficult to accurately align the assembly pieces to the preset installation nodes, but also prolongs the adjustment time of individual components, making the assembly process of the entire cover extremely cumbersome. Moreover, this hoisting deviation also poses a significant safety risk: on the one hand, the shaking assembly pieces may collide with the furnace metal frame, causing damage to the refractory material corners and affecting the sealing of the cover; on the other hand, if the lifting cable suddenly slips due to uneven force or the assembly pieces fall accidentally, it is easy to cause personal injury to the operators below, posing a serious safety hazard to production.

[0047] The following refers toFigures 1-13 The application provides a spherical top cover of refractory material and a whole mounting device thereof.
[0048] The application provides a spherical top cover of refractory material and a whole mounting device thereof.
[0049] When the mounting of the assembling plate 300 on the top of the sintering furnace 400 is performed, the lifting frame 100 is first placed on the ground, the bottom of the assembling plate 300 is contacted with the bottom of the supporting plate 120, and the assembling plate 300 is attached to the outer sidewall of the auxiliary plate 110, then the lifting frame 100 is lifted and hoisted to the position where the spherical top cover needs to be installed on the top of the sintering furnace 400, the auxiliary plate 110 is overlapped with the position on the top of the sintering furnace 400, and the assembling plate 300 is overlapped with the position where the spherical top cover needs to be installed.
[0050] It is to be noted that the assembling plate 300 needs to be installed layer by layer, if the lifting frame 100 only lifts one layer, the installation efficiency is low, but if two layers are lifted, the assembling plate 300 is prone to falling off during the lifting process, therefore, the clamping assembly 200 is arranged on the auxiliary plate 110, the clamping assembly 200 can clamp the assembling plate 300 on the auxiliary plate 110, so that the assembling plate 300 is prevented from separating from the auxiliary plate 110, the clamping assembly 200 in the application clamps the connecting position of two layers of assembling plate 300, so that the lifting frame 100 can lift two layers at a time, the installation efficiency is improved, and the falling off of the assembling plate 300 is avoided, the safety is improved, when the lifting frame 100 lifts the two layers of assembling plate 300 to the top of the sintering furnace 400, the supporting plate 120 at the bottom of the auxiliary plate 110 is moved inward along the radial direction of the auxiliary plate 110, so that the supporting plate 120 separates from the assembling plate 300, at this time, the assembling plate 300 falls to the position on the top of the sintering furnace 400, then the clamping assembly 200 separates from the clamping of the two layers of assembling plate 300, so that the operator can fix the two layers of assembling plate 300 on the top of the sintering furnace 400, then the lifting frame 100 is removed, and the above operation is repeated, so that the spherical top cover on the top of the sintering furnace 400 is gradually assembled.
[0051] It should be noted that when the size of the auxiliary plate 110 is large, multiple assembly plates 300 can be conveyed at one time, and when the size of the auxiliary plate 110 is small, the amount of conveyed assembly plates 300 is reduced. The size of the auxiliary plate 110 is determined according to actual needs, and is not specifically limited herein.
[0052] Specifically, the clamping assembly 200 in the embodiment includes a clamping chain plate and a conveying roller 210, the conveying roller 210 is rotationally arranged on the auxiliary plate 110, and the clamping chain plate is arranged around the outer periphery of the conveying roller 210. The conveying roller 210 can convey and wind the clamping chain plate. The clamping chain plate is configured to be attached to the assembly plate 300 when it is separated from the conveying roller 210. The shape of the clamping chain plate when it is unfolded is a fan ring shape, so that it can be attached to the assembly plate 300. The clamping chain plate can maintain the state of being attached to the assembly plate 300, thereby playing a clamping role on the assembly plate 300. When the assembly plate 300 is placed on the auxiliary plate 110, the lifting frame 100 is first lifted to the ground. Then, the assembly plate 300 is attached to the auxiliary plate 110, and the assembly plate 300 is assembled in two layers. Then, the conveying roller 210 is driven, and the conveying roller 210 outputs the clamping chain plate, so that the clamping chain plate can be attached to the connection position of the two layers of assembly plates 300. The clamping chain plate clamps and fixes the two layers of assembly plates 300. Then, the lifting frame 100 lifts the two layers of assembly plates 300 to the top of the sintering furnace 400.
[0053] More specifically, the clamping chain plate in the embodiment comprises a plurality of connecting rollers 230 and a plurality of connecting plates 260, a spline shaft 250 is axially elastically slidably arranged on both ends of the plurality of connecting rollers 230, that is, a limiting groove 231 is formed on both ends of the connecting roller 230, a spring 232 is arranged in the limiting groove 231, the spline shaft 250 is axially slidably connected in the limiting groove 231, a limiting strip is arranged in the limiting groove 231 to limit the rotation of the spline shaft 250, the spline shaft 250 abuts against the spring 232, and a spline is coaxially and fixedly arranged on the outer periphery of the spline shaft 250, the end of the spline shaft 250 extending out of both ends of the connecting roller 230 is a light rod portion 251, and the portion of the spline shaft 250 located in the connecting roller 230 has a spline portion 252, a key groove 261 is formed on both ends of the connecting plate 260, the light rod portion 251 of the spline shaft 250 is rotationally connected with the key groove 261 on both ends of the connecting plate 260, the upper top pressing plate 220 is arranged on the upper and lower end faces of the conveying roller 210, the size of the upper top pressing plate 220 is larger than the size of the lower top pressing plate 220, so that the plurality of connecting rollers 230 form a fan ring shape when expanded, and form a frustum structure when wound together, at the same time, the shape of the conveying roller 210 is also a frustum structure, the diameter of the circle formed by the connecting rollers 230 wound together is smaller than the diameter of the circle formed below, the guide rail 221 is formed on the top pressing plate 220, the length of the guide rail 221 of the upper top pressing plate 220 is longer than the length of the guide rail 221 of the lower top pressing plate 220, the light rod portion 251 of the spline shaft 250 extends into the guide rail 221 and can slide in the guide rail 221.
[0054] The guide rail 221 has two parts, a winding section 222 and a guiding section 223. The curvature of the winding section 222 is the same as that of the winding roller, so that the connecting roller 230 can revolve around the conveying roller 210 when sliding in the winding section 222. The vertical distance between the two top pressing plates 220 is slightly greater than the length of the connecting roller 230, so that when the light rod part 251 at the end of the spline shaft 250 enters the guide rail 221, the guide rail 221 pushes the two spline shafts 250 to retract a part at both ends of the connecting roller 230, and at this time, the light rod part 251 at both ends of the spline shaft 250 is rotationally connected with the key groove 261 of the two connecting plates 260. The curvature of the guiding section 223 is the same as that of the auxiliary plate 110, and since the curvature of the auxiliary plate 110 is the same as that of the assembly plate 300, the curvature of the guiding section 223 is also the same as that of the assembly plate 300, so that when the conveying roller 210 moves in the guiding section 223, the curvature of the guiding section 223 can form the same state as the curvature of the assembly plate 300. When the connecting roller 230 is separated from the guiding section 223 of the guide rail 221, the spline shafts 250 at both ends of the connecting roller 230 are separated from the guide rail 221, the spline shafts 250 are no longer limited by the guide rail 221, the spring 232 abutting against the spline shaft 250 restores the deformation and re-elongates the spline shaft 250, so that the spline part 252 of the spline shaft 250 can pass through the key groove 261 of the connecting plate 260, and at this time, the spline of the spline shaft 250 cooperates with the key groove 261 of the two connecting plates 260 to limit the rotation of the connecting plate 260 around the spline shaft 250, thereby limiting the state of the plurality of connecting plates 260 and the connecting roller 230, that is, the plurality of connecting plates 260 and the plurality of connecting rollers 230 form an integral whole, so that the curvature of the integral whole of the connecting plate 260 and the connecting roller 230 is the same as that of the assembly plate 300, thereby being able to clamp the assembly plate 300. It can be understood that the assembly plate 300 is limited by the integral whole formed by the plurality of connecting plates 260 and the plurality of connecting rollers 230 on the outside, the assembly plate 300 is limited by the auxiliary plate 110 on the inside, and the assembly plate 300 is limited by the support plate 120 on the bottom, so that the assembly plate 300 has three parts limited, thereby greatly improving the safety of the transportation process.
[0055] It should be noted that the depth of the limiting groove 231 is set to be the same as the length of the spline shaft 250 in this embodiment, and two-thirds of the length of the outer periphery of the spline shaft 250 is the spline part 252, and one-third is the light rod part 251. The length of the spring 232 when compressed to the limit in the limiting groove 231 is one-third of the length of the spline shaft 250, and the thickness of a single connecting plate 260 is one-sixth of the length of the spline shaft 250, as shown in Figure 11As shown, due to the spline shaft 250 connecting two connecting plates 260 (similar to the transmission chain structure of a bicycle), the thickness of the two spline grooves 261 is one third of the length of the spline shaft 250, and the distance between the two top pressing plates 220 is set to be the sum of the length of the connecting roller 230 and the thickness of the four connecting plates 260. Since the limiting grooves 231 are arranged inside the connecting roller 230, the length of the connecting roller 230 is longer than the sum of the lengths of the two limiting grooves 231. The ends of the guide rails 221 are provided with inclined surfaces to facilitate the entry and disengagement of the light pole part 251 of the spline shaft 250 into the guide rails 221. When the spline shaft 250 enters the guide rails 221, the spline shaft 250 at both ends of the connecting roller 230 is squeezed into the limiting grooves 231, thereby compressing the springs 232. However, the springs 232 are not compressed to the limit. At this time, the length of the connecting roller 230 extending out of the limiting grooves 231 is greater than one third, so that the light pole part 251 is fully extended, and a small part of the spline part 252 is extended. The light pole part 251 enters the inside of the guide rails 221 after passing through the spline grooves 261 of the two connecting plates 260, thereby moving along the guide rails 221. At this time, only the spline groove 261 close to the connecting roller 230 is restricted from rotating by the small part of the spline part 252 of the spline shaft 250 extending out, and the other spline groove 261 can still rotate, that is, the two connecting plates 260 can still rotate relative to the spline shaft 250. When the spline shaft 250 disengages from the guide rails 221, the spline groove 261 on the connecting plate 260 disengaging from the guide rails 221 corresponds to the spline position on the outer periphery of the spline shaft 250. Since the spline shaft 250 disengages from the guide rails 221, the springs 232 push the spline shaft 250 to extend, so that the spline on the outer periphery of the spline shaft 250 can cooperate with the spline grooves 261 of the two connecting plates 260. In turn, the cooperation of the spline on the outer periphery of the spline shaft 250 and the spline grooves 261 restricts the rotation of the two connecting plates 260, so that the connecting plates 260 and the connecting roller 230 maintain the current state and in turn clamp the assembly plate 300.
[0056] It also needs to be explained that, in order to facilitate the conveying roller 210 to convey multiple connecting rollers 230, a poking plate 211 is arranged on the outer periphery of the conveying roller 210, the poking plate 211 is uniformly distributed on the outer periphery of the conveying roller 210, and the distance between the poking plates 211 is the same as the gap distance between the two connecting rollers 230, so that when the conveying roller 210 rotates, multiple connecting rollers 230 are conveyed into or out of the winding section 222 and the guide section 223 of the guide rail 221 through the poking plate 211, and in order to facilitate the rotating connection of the conveying roller 210 to the auxiliary plate 110, a fixed plate 212 is fixedly arranged on the side edge of the auxiliary plate 110 in the embodiment, the fixed plate 212 is fixedly connected to the auxiliary plate 110 through a connecting rod 213, the conveying roller 210 is rotatably connected to the fixed plate 212, and the two pressing plates 220 are also fixedly connected to the fixed plate 212 and located at the upper and lower end face positions of the conveying roller 210; in order to facilitate the rotation of the conveying roller 210, a driving motor 214 is arranged on the fixed plate 212, the rotating shaft of the driving motor 214 is coaxial with and fixedly connected to the conveying roller 210, and the driving motor 214 can drive the conveying roller 210 to rotate when started.
[0057] In further embodiments, the outer peripheries of the multiple connecting rollers 230 are coaxial and sleeved with a rolling sleeve 240, as shown in Figure 12 The outer periphery of the rolling sleeve 240 is similar to the shape of a sandglass, with a small middle diameter and large diameters at both ends, so as to adapt to the connection position of the two-layer assembly plate 300, and the outer periphery of the rolling sleeve 240 is in rolling contact with the assembly plate 300. Since the multiple connecting rollers 230 are limited in rotation after being separated from the guide rail 221 by the spline shaft 250, the connecting rollers 230 and the outer periphery of the assembly plate 300 will produce sliding friction. In order to avoid this phenomenon, the rolling sleeve 240 is arranged on the outer periphery of the connecting roller 230, which can convert sliding contact into rolling contact, thereby reducing the wear of the assembly plate 300.
[0058] In further embodiments, the outer periphery of the rolling sleeve 240 is further provided with a plurality of sliding rollers 241, which are uniformly distributed along the axial direction of the rolling sleeve 240 and have axes parallel to each other. When the lifting frame 100 hoists the assembly plate 300 to the top position of the sintering furnace 400, the support plate 120 needs to be moved radially inward along the auxiliary plate 110 to disengage from the assembly plate 300. After the support plate 120 disengages from the assembly plate 300, the two layers of assembly plates 300 will move downward to contact the top position of the sintering furnace 400. At this time, the assembly plate 300 will rub against the outer periphery of the rolling sleeve 240. Based on this, a plurality of sliding rollers 241 are arranged on the outer periphery of the rolling sleeve 240. When the support plate 120 is moved radially along the auxiliary plate 110 to disengage from the assembly plate 300, the plurality of connecting rollers 230 move along the circumferential direction of the assembly plate 300 to make the plurality of rolling sleeves 240 rotate. The sliding rollers 241 on the outer periphery of the plurality of rolling sleeves 240 rollingly contact the assembly plate 300. When the assembly plate 300 moves downward, it will convert sliding friction into rolling friction under the action of the plurality of sliding rollers 241, thereby reducing the wear of the assembly plate 300. Similarly, a sliding roller 241 can also be arranged on the outer side wall of the auxiliary plate 110 to reduce the wear of the assembly plate 300 by the auxiliary plate 110. The specific arrangement is not limited herein.
[0059] It should be noted that, since the rolling sleeve 240 on the outer periphery of the connecting roller 230 will rotate when being output by the conveying roller 210 to contact the surface of the assembly plate 300, when the plurality of connecting rollers 230 stop moving, it is necessary to ensure that the plurality of sliding rollers 241 can rotate to a position away from the assembly plate 300. Therefore, the specific position of the plurality of sliding rollers 241 on the outer periphery of the rolling sleeve 240 before starting to move is calculated according to the distance traveled by each connecting roller 230 from starting to moving to stopping, and according to the circumference of the rolling sleeve 240 on the outer periphery of the connecting roller 230, so as to ensure that the plurality of sliding rollers 241 on the rolling sleeve 240 on the outer periphery of the connecting roller 230 are away from the surface of the assembly plate 300 when the connecting roller 230 stops moving.
[0060] For example, it is assumed that one of the connecting rollers 230 needs to travel a distance of 1 meter from starting to moving to stopping, and it is assumed that the circumference of the rolling sleeve 240 is 10 centimeters, that is, the rolling sleeve 240 will stop after rotating 10 times. In order to ensure that the plurality of sliding rollers 241 on the outer periphery of the rolling sleeve 240 are away from the surface of the assembly plate 300 when stopping, it is necessary to ensure that the plurality of sliding rollers 241 are in a state of facing away from the surface of the assembly plate 300 when the rolling sleeve 240 starts to rotate. Therefore, when the rolling sleeve 240 stops moving after rotating 10 times, it can be ensured that the sliding rollers 241 are away from the surface of the assembly plate 300. The adjustment mode of the other rolling sleeves 240 is the same as described above, and will not be described again.
[0061] When all the connecting rollers 230 are clamped to the assembly plate 300, the sliding rollers 241 on the rolling sleeves 240 around the periphery are all directed to the same direction, so that when the connecting rollers 230 move along the circumference of the assembly plate 300, the sliding rollers 241 on all the rolling sleeves 240 can be ensured to contact the surface of the assembly plate 300 at the same time.
[0062] Specifically, the support plate 120 is arranged to move along the radial direction of the auxiliary plate 110, and a slope is arranged on the top of the support plate 120, and the slope on the top of the support plate 120 is inclined along the radial direction of the auxiliary plate 110, that is, the slope on the top of the support plate 120 coincides with the radial direction of the auxiliary plate 110. Since there are two symmetrical auxiliary plates 110 in the embodiment, the two auxiliary plates 110 are arc-shaped spherical plates, and the arc surfaces of the two auxiliary plates 110 are part of a complete spherical surface, so that the plurality of assembly plates 300 on the outer side walls of the two auxiliary plates 110 can form a complete spherical top cover, and the ball center of the auxiliary plate 110 coincides with the ball center of the assembly plate 300. Therefore, when the slope on the top of the support plate 120 passes through the radial direction of the auxiliary plate 110, the assembly plate 300 can be completely attached to the top of the sintering furnace 400 to form a spherical top cover.
[0063] More specifically, in the embodiment, the support plate 120 is arranged to move along the radial direction of the auxiliary plate 110, a drive gear 111 is arranged on the bottom of the auxiliary plate 110, and a rack 121 is arranged on the slope on the top of the support plate 120. The bottom of the support plate 120 is a flat surface, the drive gear 111 is engaged with the rack 121, and when the drive gear 111 rotates, the support plate 120 can be driven to separate from the bottom of the assembly plate 300 through the engaged rack 121, so that the bottom of the assembly plate 300 can contact the top of the sintering furnace 400.
[0064] In a further embodiment, in order to facilitate the lifting frame 100 to separate from the top of the sintering furnace 400 and separate from the assembly plate 300, the upper ends of the two auxiliary plates 110 in the embodiment are hinged to the lifting frame 100, and a telescopic cylinder 130 is vertically arranged on the lifting frame 100. The telescopic cylinder 130 is configured to rotate the two auxiliary plates 110 around the hinge position when it is extended or retracted, so that the two auxiliary plates 110 are away from the assembly plate 300 after the assembly plate 300 is installed, facilitating the lifting of new assembly plates 300 after separating from the top of the sintering furnace 400.
[0065] Specifically, the fixed end of the telescopic cylinder 130 is fixedly connected to the lifting frame 100, the telescopic end of the telescopic cylinder 130 is fixedly connected with a connecting ring 140, the outer periphery of the connecting ring 140 is provided with two connecting rods 150, one end of the two connecting rods 150 is hingedly connected with the outer periphery of the connecting ring 140, and the other end of the connecting rod 150 is hingedly connected with the middle position of the auxiliary plate 110, so that when the telescopic end of the telescopic cylinder 130 is extended or shortened, the two auxiliary plates 110 can be pushed to rotate around the hinged position through the connecting ring 140 and the connecting rod 150.
[0066] The specific working process of the whole installation equipment for the spherical top cover of the refractory material provided by the application is described in combination with the above embodiment.
[0067] The lifting frame 100 is lifted to the ground and placed on the assembling plate 300.
[0068] The operator controls the large lifting machine to move the lifting frame 100 to the ground, drives the telescopic cylinder 130 to be shortened, so that the two auxiliary plates 110 are spread apart, and the bottom of the two auxiliary plates 110 can correspond to the top of the sintering furnace 400, then the operator places a plurality of assembling plates 300 on the two auxiliary plates 110, and places the plurality of assembling plates 300 in two layers, the upper end of the lower layer of assembling plates 300 is connected with the lower end of the upper layer of assembling plates 300, then the driving motor 214 is started, the driving motor 214 drives the conveying roller 210 to rotate, the conveying roller 210 drives a plurality of connecting rollers 230 and connecting plates 260 to move along the guide rail 221 through the toggle plate 211, since the curvature of the guide section 223 of the guide rail 221 is the same as the curvature of the spherical top cover formed by the plurality of assembling plates 300, when the plurality of connecting rollers 230 and connecting plates 260 move in the guide section 223, the overall curvature formed is the same as the curvature of the spherical top cover, and when the spline shaft 250 at both ends of the connecting roller 230 is separated from the guide section 223, the spline on the outer periphery of the spline shaft 250 cooperates with the key groove 261 of the two connecting plates 260, so as to fix the state of the connecting roller 230 and the connecting plate 260 separated from the guide section 223, so that the plurality of connecting rollers 230 and connecting plates 260 form an overall body capable of clamping the plurality of assembling plates 300, specifically clamping at the connection position of the two layers of assembling plates 300, with the rotation of the driving motor 214, the driving motor 214 stops conveying after conveying most of the connecting rollers 230 and connecting plates 260 to the surface of the assembling plate 300, at this time, the plurality of sliding rollers 241 on the rolling sleeve 240 on the outer periphery of the connecting roller 230 are all directed to the same direction and away from the surface of the assembling plate 300.
[0069] The lifting frame 100 is lifted to the top of the sintering furnace 400 and fixedly connected with the assembling plate 300.
[0070] The operator operates a large crane to hoist the lifting frame 100 to the top of the sintering furnace 400, and centers the auxiliary plate 110 with the top of the sintering furnace 400, and then lowers the lifting frame 100, and when the auxiliary plate 110 contacts the top of the sintering furnace 400, the lowering is stopped, the driving gear 111 is rotated to drive the support plate 120 to move along the radial direction of the auxiliary plate 110, and gradually separates from the bottom of the assembly plate 300, and when the support plate 120 completely separates from the bottom of the assembly plate 300, the conveying roller 210 is reversely driven, the conveying roller 210 drives the plurality of connecting rollers 230 to move along the circumferential direction of the assembly plate 300, so that the plurality of sliding rollers 241 on the plurality of rolling sleeves 240 are simultaneously rotated to a position in rolling contact with the assembly plate 300, and the assembly plate 300 is moved under the action of gravity, so as to contact the top of the sintering furnace 400, and in the process of moving downward of the assembly plate 300, the plurality of sliding rollers 241 on the outer periphery of the rolling sleeve 240 are in rolling contact with the surface of the assembly plate 300, so as to reduce the abrasion of the assembly plate 300, and when the assembly plate 300 contacts the top of the sintering furnace 400, the operator fixes the plurality of assembly plates 300 on the top of the sintering furnace 400, and then drives the telescopic cylinder 130 to extend, and the telescopic cylinder 130 drives the two auxiliary plates 110 to rotate around the hinge position through the connecting ring 140 and the connecting rod 150, so as to be retracted together, and finally the lifting frame 100 is lifted, so that the lifting frame 100 is separated from the top of the sintering furnace 400, and after being separated, the telescopic cylinder 130 is shortened again, so as to reset the two auxiliary plates 110.
[0071] Then the lifting frame 100 is hoisted to the ground again to place new assembly plates 300, and the above operation is repeated, until most of the assembly plates 300 are installed and fixed on the top of the sintering furnace 400, and a group of symmetrical gaps are left, which cannot be installed by the device, and can only be installed manually, and finally the circular arc gap left on the top is used to hoist the top circular plate (not shown in the figure) of the spherical top cover on the circular arc gap by using the crane, so as to complete the installation of the whole refractory spherical top cover.
[0072] The application also provides a whole refractory spherical top cover installation process, which specifically comprises the following steps.
[0073] S100, first, a plurality of assembly plates 300 are placed on the auxiliary plate 110 of the lifting frame 100, and the support plate 120 supports the bottom of the assembly plate 300;
[0074] S200, then the clamping assembly 200 is started to clamp the plurality of assembly plates 300 on the auxiliary plate 110, and the lifting frame 100 is hoisted to the top of the sintering furnace 400;
[0075] S300, drive the support plate 120 to move along the auxiliary plate 110 radially to make the bottom of the plurality of assembly plates 300 contact the top of the sintering furnace 400, then release the clamping of the clamping assembly 200 and withdraw the lifting frame 100 from the top of the sintering furnace 400, cycle in turn, and finally manually block the gap.
