DETAILED DESCRIPTION

[0032] In order to make the purpose, technical scheme and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention, that is, the embodiments described are only part of the embodiments of the present invention, rather than all of the embodiments. The components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0033] Depend on Figures 1 to 7 The invention provides a protective frame 101 and a mobile platform 102 located below the protective frame 101. A track 141 is provided on the ground for the reciprocating movement of the mobile platform 102. A driving device is installed inside the mobile platform 102 so that the mobile platform 102 can move along the track 141. One side of the protective frame 101 is opened. The open side of the protective frame 101 is connected to a lifting frame 103. An observation plate 104 is connected to the inner side of the lifting frame 103 so as to slide up and down. The observation plate 104 can move up and down on the lifting frame 103. When the wire feeding action is performed, the observation plate 104 is lowered to play a protective role. When the mobile platform 102 moves, the observation plate 104 will be located at the top. The top of the protective frame 101 is connected to a guide frame 105, a wire feeding device 106 and a driving assembly 107 to feed the cored wire. One end of the wire is guided by the guide frame 105 into the wire feeding device 106, and the wire feeding device 106 feeds the cored wire into the crucible at the bottom through the hollow tube 111. The wire feeding device 106 is an existing device and will not be described in detail here. A cover 108 is provided inside the protective frame 101, and an airflow cover 109 is connected to the top of the cover 108. The cover 108 cooperates with the top of the crucible and can cover the crucible. The airflow cover 109 on the top is used to discharge the generated high-temperature gas for recycling. One end of the airflow cover 109 is connected to an airflow recovery pipeline 110, and the bottom of the wire feeding device 106 is connected to a hollow tube 111 that penetrates the airflow cover 109. The hollow tube 111 is made of a high-temperature resistant hard material, and is used for conveying the cored wire inside and guiding the up and down movement of the cover 108 outside.

[0034] refer to Figure 4 and Figure 5The driving assembly 107 includes a threaded rod 112 and a driven rod 113 located on the same axis. The threaded rod 112 and the driven rod 113 are on the same axis but do not contact each other. When the movable chuck 122 at one end of the driven rod 113 comes into contact with the fixed chuck 120, the threaded rod 112 and the driven rod 113 are linked. The top of the protective frame 101 is connected to a motor 114, and the output end of the motor 114 is connected to the threaded rod 112. A movable plate 115 is threadedly connected to the outer wall of the threaded rod 112. When the threaded rod 112 rotates, it will drive the movable plate 115 to move. The two sides of the movable plate 115 are rotatably connected with symmetrically arranged rollers 116. The top of the lifting frame 103 and the side close to the protective frame 101 are connected with rollers 116. The top of the observation plate 104 is connected to a first steel wire rope 117. The direction of the first steel wire rope 117 is referenced Figures 1 to 3 , one end of the first steel wire rope 117 passes through a plurality of rollers 116 in sequence and is connected to one side of the lifting frame 103. Specifically, when the movable plate 115 moves toward the side away from the motor 114, the movable plate 115 drives the first steel wire rope 117 to move through the roller 116, so that the other end of the first steel wire rope 117 pulls the observation plate 104 to move upward;

[0035] refer to Figure 3 and Figure 7 The top of the protective frame 101 is connected to a roller 118, and a second steel wire rope 119 is wound around the roller 118. The second steel wire rope 119 is wound around the roller 118, and the roller 118 drives one end of the second steel wire rope 119 to move up and down by rotation. One end of the second steel wire rope 119 is connected to the top of the cover 108. The end of the threaded rod 112 away from the motor 114 is connected to a fixed chuck 120. The outer wall of the end of the driven rod 113 close to the threaded rod 112 is provided with a spline portion 121. The movable chuck 122 is moved by The spline portion 121 moves to one end of the driven rod 113, and a moving chuck 122 is slidably connected to the spline portion 121. The fixed chuck 120 and the moving chuck 122 are provided with mutually meshing tooth surfaces on the opposite side. The fixed chuck 120 and the moving chuck 122 are connected through the tooth surfaces, so that the threaded rod 112 and the driven rod 113 are connected together. The end of the driven rod 113 away from the moving chuck 122 is connected to the roller 118 through a bevel gear transmission assembly 123. The specific connection structure of the bevel gear transmission assembly 123 is referred to Figure 7 .

[0036] Specifically, refer to Figure 4 and Figure 5, strip brackets 124 are provided on both sides of the threaded rod 112, and a spline rod 125 is connected to the top of the strip bracket 124. A moving rod 126 is splined on the outer wall of the spline rod 125, and the moving rod 126 moves laterally on the spline rod 125. A movable plate 115 is slidably provided on the outer wall, and both ends of the movable plate 115 are slidably connected to the outer wall of the moving rod 126. The end of the moving rod 126 close to the motor 114 is connected to the strip bracket 124 through a spring 127, and the end of the moving rod 126 away from the motor 114 is fixedly connected to a driven plate 128, and one end of the moving rod 126 is connected to a spring 127, and the spring 127 is in a compressed state, which is used to push the moving rod 126 to move toward the other end. A through hole is provided in the middle of the movable plate 128, which is rotatably connected to the driven rod 113. A bearing 129 is connected to the side of the driven plate 128 close to the movable chuck 122. When the fixed chuck 120 drives the movable chuck 122 to rotate, the movable chuck 122 drives the spring 127 to rotate on the bearing 129, which does not affect the positional relationship between the movable plate 128 and the driven plate 128. The bearing 129 and the movable chuck 122 are connected by the spring 127. Specifically, when the movable rod 126 is located on the side away from the motor 114, the movable chuck 122 will not contact the fixed chuck 120. When the movable rod 126 moves to the side close to the motor 114, the driven plate 128 will push the movable chuck 122 to press on the fixed chuck 120 through the spring 127.

[0037] refer to Figure 5 The threaded rod 112 is provided with an idle part 130 at one end close to the motor 114. The idle part 130 is not provided with threads and has a diameter smaller than the threaded part. Specifically, when the movable plate 115 moves to the side close to the motor 114, the observation plate 104 has moved to the bottom of the lifting frame 103 to play a protective role. After moving to the idle part 130, the two ends will drive the moving rod 126 to move. Since the idle part 130 has no threads, even if the threaded rod 112 continues to rotate, it will not affect the movable plate 115.

[0038] After the wire feeding is completed, it is necessary to open the cover 108 first, and then open the observation plate 104 to facilitate the crucible to be sent out. The process is very cumbersome, and it is also necessary to observe whether it is closed in place. The following provides a structure in which the driven rod 113 rotates first and then the movable plate 115 moves: Specifically, refer to Figures 3 to 7The top of the airflow cover 109 is connected to an extrusion frame 131, the inner top of the protective frame 101 is connected to a first extrusion box 132, and one side of the strip bracket 124 is connected to a first driven box 133. When the first extrusion box 132 is squeezed, the internal hydraulic oil will enter the first driven box 133, driving the output end of the first driven box 133 to move. An oil delivery pipeline 134 is connected between the first extrusion box 132 and the first driven box 133. The first driven box 133 is connected to an inclined plane block 135. When the output end of the first driven box 133 is extended, the inclined plane block 135 will contact the rotating wheels 136 at both ends of the movable plate 115. Specifically, when the inclined plane block 135 is extended, the movable plate 115 will be moved by the inclined plane. The plate 115 is pushed toward the end close to the motor 114 for a distance to prevent the threaded rod 112 from driving the driven rod 113 to rotate. When the roller 118 rotates to drive the bag cover 108 to move upward, the movable plate 115 contacts the threads of the threaded rod 112, thereby causing movement, so that after the bag cover 108 moves to the top to squeeze the first squeezing box 132, the inclined surface block 135 retracts into the first driven box 133, and then the spring 127 pushes the movable plate 115 to contact the threads on the threaded rod 112, thereby driving the movable plate 115 to move. At this time, the driven plate 128 is also reset, and the movable chuck 122 on one side is disengaged from the fixed chuck 120. The two ends of the movable plate 115 are rotatably connected with rotating wheels 136 corresponding to the inclined surface block 135.

[0039] The driven rod 113 lacks a fixed structure and will rotate when it is not connected to the threaded rod 112. The following provides a structure that can clamp and fix it: Figure 5 and Figure 6 Specifically, the top of the protective frame 101 is connected to a second extrusion box 137 located on both sides of the motor 114, and the output end of the second extrusion box 137 is arranged toward the movable plate 115. When the movable plate 115 moves to the idling part 130, it will come into contact with the second connecting rod 303 on the second extrusion box 137, thereby squeezing it. The outer wall of the driven rod 113 is connected to an inner brake pad 138, and a second driven box 139 is provided on both sides of the driven rod 113. The second driven box 139 is connected to an outer brake pad 140 that matches the inner brake pad 138. When the second extrusion box 137 is squeezed, the internal hydraulic oil enters the second driven box 139 through the oil pipeline 134, thereby driving the outer brake pad 140 on the second driven box 139 to separate from the inner brake pad 138.

[0040] Specifically, refer to Figure 6The first extrusion box 132 and the second extrusion box 137 include a first protective cover 201 and a first movable plate 202 slidably connected to the first protective cover 201. One side of the first movable plate 202 is connected to a first connecting rod 203 extending from the first protective cover 201. When the first connecting rod 203 is squeezed, it will drive the first movable plate 202 to move, and the spring 127 on the other side is compressed. At the same time, hydraulic oil enters the oil pipeline 134. A spring 127 is connected between one end of the first movable plate 202 away from the second connecting rod 303 and the first protective cover 201. The spring 127 is in a compressed state. The chamber of the first movable plate 202 close to the spring 127 is filled with hydraulic oil and connected to the oil pipeline 134.

[0041] Specifically, refer to Figure 6 The first driven box 133 and the second driven box 139 include a second protective cover 301 and a second movable plate 302 slidably connected to the second protective cover 301. One side of the second movable plate 302 is connected to a second connecting rod 303 extending from the second protective cover 301. When the hydraulic oil enters the second protective cover 301 through the oil pipeline 134, it will push the second movable plate 302 to move, thereby compressing the spring 127 on the other side. The spring 127 is connected between the end of the second movable plate 302 away from the second connecting rod 303 and the second protective cover 301, and the spring 127 is in a compressed state. The chamber of the second movable plate 302 away from the spring 127 is filled with hydraulic oil and is connected to the oil pipeline 134. Specifically, the first extrusion box 132 is connected to the first driven box 133 through the oil pipeline 134, and the second extrusion box 137 is connected to the second driven box 139 through the oil pipeline 134.

[0042] Specifically, refer to Figure 1 and Figure 2 A track 141 is provided at the bottom of the mobile platform 102, and a driving wheel device is installed inside the mobile platform 102. The driving wheel device drives the mobile platform 102 to move along the track 141. The mobile platform 102 moves on the track 141. A triangular positioning block 142 is connected to the top of the mobile platform 102. The triangular positioning block 142 facilitates the positioning of the crucible.

[0043] Specifically, refer to Figure 2The airflow cover 109 is connected to a baffle 143 inside, which prevents the rolling molten metal from building onto the airflow duct of the airflow cover 109 during wire feeding. The top of the baffle 143 is used for the passage of airflow. The top of the airflow cover 109 is connected to a sleeve 144, which slides up and down along the outer wall of the hollow tube 111, and the hollow tube 111 plays a guiding role. It should be noted that part of the heat will enter the hollow tube 111 during the wire feeding process, which has the effect of preheating the cored wire and will not affect the normal use of wire feeding. At the same time, outside air will enter from here.

[0044] Specifically, refer to Figure 1 An observation window 145 is connected to the top of the observation plate 104, and the observation window 145 is convenient for observing the internal situation.

[0045] When the present invention is used, one end of the cored wire is fed into the wire feeding device 106 through the guide frame 105 in advance, and the wire feeding device 106 conveys the cored wire to the hollow tube 111 at the bottom, and the crucible filled with molten metal is placed on the mobile platform 102 through a crane, and the triangular positioning block 142 on the top of the mobile platform 102 plays a positioning role. The driving device inside the pneumatic mobile platform 102 feeds the crucible into the protective frame 101, and then the motor 114 is started, and the motor 114 drives the movable plate 115 to move, and the observation plate 104 will fall down first to play a protective role, and then the top cover 108 will fall down and cover the crucible, and then the wire feeding device 106 will be controlled to feed the material. The cored wire will boil after entering the metal solution, and the generated heat will be discharged through the airflow recovery pipe 110. After the wire feeding is completed, the motor 114 is reversed, and the cover 108 will rise first. After rising to the top, the movable plate 115 will move to the thread on the threaded rod 112, thereby opening the observation plate 104. At this time, the crucible can be taken out through the movable platform 102.

[0046] The above-mentioned embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
