The casting ladle after separation is small in size, easy to operate and control, and can be flexibly turned over to pour out the molten iron and inject into the mold. After the casting ladle is filled with molten iron, the cover body can be automatically and quickly closed, because the cover body is automatically closed completely by heat drive, which avoids direct access to the high-temperature and smoky workplace around the casting ladle, and saves the power source for driving the lid to close. The simple cover or cover relying on the power source in the prior art is far less reliable and fast than the present invention that uses the heat in the container to close, and the mechanism that receives the heat to generate action is set in two levels, and the two levels act in sequence. The action of the first level relies on the principle of thermal expansion, and its position is close to the heat source center and the heat source concentration area. The heat induction coil can be expanded rapidly, but the deformation can produce The displacement is limited, and the purpose is to immediately form a lock. Similarly, as the internal metal liquid decreases and the distance from the heat source center becomes farther, the thermal induction coil will also shrink rapidly, but at this time there is a second level to complete the locking. The design of the second level is to use the pressure of the spring to complete its action displacement. It cooperates with the locking of the pawl to complete the final complete sealing. Generally, the casting bag is working continuously, that is, there is always heat in the cylinder, and the wax oil is always in a fluid state. Therefore, after opening, it is necessary to wait for the wax oil to return to a solid state before re-tightening the large nut and reusing it. Therefore, it is generally necessary to prepare two or more cycles for use. The entire capping process is simple, fast and safe, and only one action is completed when opening. The overall operation mode is a major breakthrough compared with the original mode. On-site personnel have reduced the chance of dangerous contact, reduced labor intensity, and improved production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1

[0033] like Figure 1-2As shown, a casting ladle with a quick-locking cover is arranged above the ground mold, including the conventional arrangements of the casting ladle station: a crane mechanism 01 and a mechanical arm 02; the improved parts of the casting ladle are: a turning frame 03 that relies on the crane mechanism 01 to move, a casting mechanism 04 that can be separated from the turning frame 03, a clamping device 200 arranged on the turning frame 03 to position and rotate the casting mechanism 04, and an iron ladle 001 for transferring molten iron; the mechanical arm 02 is movably mounted on the cross beam 015 of the crane mechanism 01, and the turning frame 03 is movably mounted on the translation beam 018 of the crane mechanism 01; the casting mechanism 04 mainly includes a casting ladle cylinder 041 with an open upper portion for dispensing molten iron, and a capping mechanism 100 covering the casting ladle cylinder 041; an outlet 042 is provided on the upper circumferential surface of the casting ladle cylinder 041;

[0034] During operation, the large-capacity molten iron ladle 001 receives the molten iron in front of the furnace, and is lifted to the workstation by a crane (not shown in the figure), and the molten iron is poured into the casting ladle cylinder 041 in batches. The sealing mechanism 100 is covered by the robotic arm 02, and is automatically and quickly locked under the heat of the molten iron. The clamping device 200 clamps the casting ladle cylinder 041 and rotates it so that the outlet 042 faces the side relative to the turning frame 03 away from the casting mold, so that the molten iron will not flow out from the outlet 042 when the turning frame 03 is turned. After the turning frame 03 is turned to the appropriate position, the clamping device 200 starts to rotate, and the outlet 042 of the casting ladle cylinder 041 gradually turns to the mold, and is slowly and orderly injected into the mold to complete a casting.

[0035] The outlet 042 faces the movable holder 034, and the molten iron receiving position of the guide mechanism 037 is corrected. After the rotating frame assembly 032 carries the casting mechanism 04 and flips forward to the working position, the outlet 042 faces upward. The motor 036 is adjusted to drive the casting mechanism 04 to rotate until the outlet 042 faces downward. The molten iron flows out and is injected into the mold through the guide pipe part of the guide mechanism 037, completing one casting.

[0036] like Figure 2 As shown, the driving mechanism 01 includes driving beams 011 on both sides of the site, a driving frame 013 for supporting and installing the driving beams, a span beam 015 and a translation beam 018 spanning the driving beams 011 on both sides, a long span beam seat 014 and a short span beam seat 016 for connecting and installing the span beam 015, a bearing seat 017 for connecting and installing the translation beam 018, and a longitudinal driving motor 012 for driving the span beam 015 and the translation beam 018 to move;

[0037] The traveling beam 011 is supported and fixedly connected by the traveling frames 013 erected on both sides of the work site. The bottom end of the traveling frame 013 is fixed to the ground by anchor bolts. One end of the span beam 015 is fixedly connected to the long span beam seat 014, and the other end is fixedly connected to the short span beam seat 016. The long span beam seat 014 is movably installed on the traveling beam 011 on one side, and the short span beam seat 016 is movably installed on the traveling beam 011 on the other side. The traveling beams 011 on both sides are also movably installed with bearing seats 017, and the translation beam 018 is fixed. Connected to the bottom ends of the supporting seats 017 on both sides, the longitudinal drive motor 012 is installed at one end of the traveling beam 011 on the side of the long span beam seat 014, and drives the screw transmission pair built between the traveling beam 011 and the long span beam seat 014, and the screw transmission pair between the traveling beam 011 and the supporting seat 017, so as to synchronously drive the span beam 015 and the translation beam 018 to move forward and backward along the traveling beam 011, thereby driving the mechanical arm 02 installed on the span beam 015 and the turning frame 03 installed on the translation beam 018 to move forward and backward along the traveling beam 011.

[0038] like Figure 3 As shown, the robot 02 includes a robot body 021, a slide 022 arranged at the front side of the robot body 021, a robot assembly 023, a temperature detector 024 arranged at the lower end of the side of the robot body 021, and a lateral drive motor 025 for driving the robot body 021 to move along the cross beam 015;

[0039] The robot arm body 021 is movably mounted on the span beam 015, the slide 022 is movably mounted in the slide groove on the front side of the robot arm body 021, the robot hand assembly 023 is fixed on the slide 022, and can move up and down with the slide 022, the temperature detector 024 is fixed at the lower end of the side of the robot arm body 021, and is used to detect the temperature of the molten iron, the transverse drive motor 025 is placed on the side of the long span beam seat 014, and is fixed on the end face of the span beam 015, and the screw transmission pair between the span beam 015 and the robot arm body 021 is driven to drive the robot arm 02 to move back and forth along the span beam 015, so as to realize the operations of the robot hand assembly 023 to cover, unlock and lift the capping mechanism 100 of the working casting mechanism 04;

[0040] like Figure 3As shown, the flip frame 03 includes a base assembly 031 movably mounted on the translation beam 018, a rotating frame assembly 032 mounted in cooperation with the groove wheel of the base assembly 031 through an arc track, and a translation platform 033 fixedly mounted on the inner side of the arc track of the rotating frame assembly 032. The rotating frame assembly 032 is mounted on the base assembly 031. Driven by the built-in power, the whole can be turned in an arc shape. The plane of the translation platform 033 is used to place the casting mechanism 04. The movable arm 034 is movably fixed on the rear end side beam of the rotating frame assembly 032. The fixed arm 035 is symmetrically and movably installed on the front end sliding shaft of the rotating frame assembly 032. Under the action of the cylinder provided by the movable arm 034, it cooperates with the fixed arm 035 to clamp the casting mechanism 04 placed on the translation platform 033. The contact ends of the movable arm 034, the fixed arm 035 and the casting mechanism 04 are provided with freely rotatable rollers. During the period when the casting mechanism 04 is clamped, the adjustment motor 036 drives the motor side The roller at the contact end of the fixed holder 035 is used to make radial rotation adjustment for the casting mechanism 04. The guide pipe 037 is installed at the front side end of the base assembly 031, and the position of the internal guide pipe outlet can be moved to adjust to facilitate the docking mold pouring hole. The movement of the translation platform 033 and the movement of the guide pipe 037 are all micro-adjustments of the translation of the casting mechanism 04 after the flip frame 03 is in place. The lateral movement of the flip frame 03 along the translation beam 018 is achieved by the belt drive motor 038 installed in the cavity at the lower end of the bearing seat 017 on one side, which drives the belt assembly 039 connected to the base assembly 031 to pull the flip frame 03;

[0041] like Figure 4-10 As shown, the open end surface of the casting package cylinder 041 has a stepped plane 01a, and a plurality of buckle pin holes 41a are evenly distributed on the open edge. The casting mechanism 04 also includes a roller shaft 043 rotatably mounted on the upper wall of the buckle pin hole 41a. The capping mechanism 100 mainly includes a cover body 101, and the center position of the cover body 101 is processed into a cylindrical sink cavity (see Fig.10); the capping mechanism 100 also includes a shaft handle 102 fixed at the center of the sinking cavity of the cover body 101, a heat induction coil 103 arranged in the sinking cavity of the cover body 101, a relay ring 104 for transmitting heat induction, a thrust frame 105 arranged at the upper end of the relay ring 104 for changing the thrust direction, a plurality of buckle pins 106 evenly distributed on the disc surface of the cover body 101, and a force bearing seat 107 installed at the tail end of the buckle pin 106; the roller shaft 043 can reduce the resistance of the buckle pin 106 when entering and exiting the buckle pin hole. During operation, the cover body 101 is placed on the step plane 01a. Under the action of the heat in the cylinder, the heat induction coil 103 is deformed. The deformation is transmitted and converted by the relay ring 104 and the thrust frame 105, so that the buckle pin 106 enters the buckle pin hole 41a. As a result, the cover body 101 is pressed tightly against the step plane 01a to form a seal. The specific connection structure is: the shaft handle 102 is installed and fixed at the bottom of the sink cavity, the heat induction coil 103 is sleeved on the bottom of the shaft handle 102 and buried in the sink cavity of the cover body 101, the relay ring 104 is sleeved on the shaft handle 102, the lower end face is in contact with the upper end face of the heat induction coil 103, and the upper end face is against the thrust frame 105, the thrust frame 105 is rotatably installed on the tail end face of the buckle pin 106, and the force seat 107 is fixedly installed on the upper side surface of the tail of the buckle pin 106. The displacement caused by the thermal expansion and contraction of the heat induction coil 103 is transmitted to the thrust frame 105 through the relay ring 104; the thrust frame 105 transmits the force to the buckle pin 106 through the force seat 107, causing the buckle pin 106 to move outward; the front end of the buckle pin 106 has an inclined surface, and the contact between the inclined surface and the roller shaft 043 becomes tighter as the buckle pin 106 goes deeper, forcing the cover body 101 to be pressed tightly against the step plane 01a.

[0042] In order to expand the outward movement distance of the buckle pin 106 and ensure the tight sealing, a frustum 108 is provided on the inclined surface of the force bearing seat 107, a large compression spring 109 is pressed on the upper end surface of the frustum 108, a damping oil groove 111 is provided on the plate surface of the cover body 101, and an oil drain cavity 110 is provided on the oil surface of the damping oil groove 111;

[0043] The inverted frustum 108 can be movably mounted on the shaft handle 102 up and down, and the conical surface of the lower end is pressed on the inclined surface of the force-bearing seat 107. The large compression spring 109 is mounted on the shaft handle 102 as a whole, and the lower half is overlapped on the outside of the sleeve of the upper part of the inverted frustum 108, and the lower end surface is against the upward frustum surface of the inverted frustum 108. The oil cavity part of the oil drain chamber 110 is overlapped on the oil surface in the damping oil groove 111, and the contact surface with the oil surface is processed with an oil leakage hole. After assembly, it is overlapped on the lower half of the large compression spring 109, and the wing disc of the damping oil groove 111 is stepped with the outer edge of the cover body 101. The slots of the two for installing the buckle pin 106 are overlapped and consistent, and the inner side of the oil drain chamber 110 is The bottom end surface of the sleeve part is fixedly connected with the upward truncated cone surface of the inverted cone 108. Generally, when the oil in the damping oil groove 111 loses fluidity, it plays a supporting and blocking role on the oil drain chamber 110, etc. When the oil has fluidity and can flow out of the oil groove, the supporting and blocking role disappears. Under the action of the large compression spring 109, the conical surface of the inverted cone 108 squeezes the inclined surface of the force-bearing seat 107, so that the buckle pin 106 continues to move outward. In order to lock the outward movement distance of the buckle pin 106, a pawl 112 and a pin shaft 113 for installing the pawl 112 are provided on the upper end surface of the buckle pin 106, and a fixed seat 114 of a riding structure is provided, and a small compression spring 115 and a spring seat 116 are pressed on the upper side of the pawl 112.

[0044] The pawl 112 is rotatably mounted on the pin shaft 113, and the two ends of the pin shaft 113 are fixed on the two side walls of the fixing seat 114. The lower end surfaces of the two side walls of the fixing seat 114 are fixedly connected to the disk surface of the cover body 101, and the rectangular slot hole in the center of the upper end surface covers the upper end surface of the buckle pin 106. The pawl 112 is integrally mounted in the rectangular slot hole of the fixing seat 114, and a small compression spring 115 is installed on the upper side surface of the pawl 112. The small compression spring 115 is fixed by a spring seat 116, and the spring seat 116 is fixedly mounted on the rectangular slot hole on the upper end surface of the fixing seat 114. On both sides of the pawl 112, the small compression spring 115 presses the pawl 112, keeping the claw tip of the pawl 112 stuck in the ratchet teeth on the upper end surface of the buckle pin 106, so that the outward movement state of the buckle pin 106 can be kept locked. To release the outward extension state of the buckle pin 106, it is only necessary to lift the claw tip of the pawl 112. For this purpose, a push plate 117 is provided at the raised tail end of the pawl 112, a slide seat 118 for installing the push plate 117, a return spring 119 for returning the push plate 117, an eccentric wheel 120 provided at the upper end of the push plate 117, and a spring 121 provided at the rear end of the upper side of the buckle pin 106;

[0045] The two push rods of the push plate 117 are slidably installed in the two sliding holes of the slide seat 118, and the middle bridge section is pressed on the upper end surface of the return spring 119. The slide seat 118 is fixedly installed on the wing disc 118a surface expanded outward of the damping oil groove 111. The return spring 119 is inserted into the spring installation hole between the two sliding holes of the slide seat 118. The eccentric wheel 120 is installed on the slide seat 118 and pressed on the middle concave part of the upper end of the push plate 117. The spring 121 is installed between the force-bearing seat 107 and the slide seat 118, and the two end heads are respectively against the force-bearing seat 107 and the inverted round table 108. The rotation of the heart wheel 120 and the push of the reset spring 119 can make the push plate 117 move up and down, and the claw tip of the ratchet 112 is lifted and lowered. When the claw tip of the ratchet 112 is lifted, the lock of the buckle pin 106 is released, and the spring 121 pushes the force bearing seat 107 to move inward, driving the buckle pin 106 to retract; the rotation of the eccentric wheel 120 is pulled by the pull rod 122 set thereon, and a pull rod seat 123, a ring seat 124 for fixing the pull rod seat 123, a large nut 125 set at the upper end of the ring seat 124, and a shaft handle head 126 set at the head of the shaft handle 102 are provided in matching arrangement;

[0046] One end of the pull rod 122 is connected to the eccentric wheel 120, and the other end is connected to the pull rod seat 123. The pull rod seat 123 is evenly fixed on the ring seat 124. The ring seat 124 is sleeved on the shaft handle 102, and the lower end face is in contact with the upper end face of the large compression spring 109. The upper section of the shaft handle 102 is processed with threads. The large nut 125 is screwed on the shaft handle 102. The large nut 125 rotates up and down along the shaft handle 102, and the expansion and contraction of the large compression spring 109 against the lower end face of the ring seat 124 can make the ring seat 124 move up and down, driving the pull rod 122 to pull the eccentric wheel 120 to rotate eccentrically. The shaft handle head 126 screwed and installed on the head of the shaft handle 102 can be used as the end position of the large nut 125 on the one hand, and is used as a gripper for lifting the capping mechanism 100 on the other hand.

[0047] During operation, the casting ladle cylinder 041 is parked on the translation platform 033 of the turning frame 03, with the outlet 042 facing the side of the movable arm 034. The cylinder of the movable arm 034 is started, and cooperates with the fixed arm 035 to clamp and fix the casting mechanism 04. The longitudinal drive motor 012 is started, and the cross beam 015 and the translation beam 018 are synchronously driven to drive the mechanical arm 02 and the turning frame 03 to shift longitudinally. The belt drive motor 038 is started to drive the turning frame 03 to shift horizontally, and the casting mechanism 04 is moved to the working position. The molten iron ladle 001 receives the molten iron in front of the smelting furnace and transports it to the casting machine. The molten iron ladle 001 is withdrawn to the storage place, and the horizontal drive motor 025 is started to drive the mechanical arm 02 to the top of the casting mechanism 04. The temperature measuring device 024 measures the temperature parameters of the molten iron. The mechanical arm assembly 023 clamps the shaft handle head 126 and lifts the sealing mechanism 100 to the top of the casting ladle barrel 041. The mechanical arm assembly 023 rotates to adjust the position of the buckle pin 106 of the sealing mechanism 100 to be consistent with the position of the buckle pin hole at the open end of the casting ladle barrel 041. The slide seat 022 moves down and the mechanical arm assembly 023 is rotated. Component 023 covers the cover mechanism 100 on the open step surface of the casting ladle barrel 041. The high temperature of the molten iron causes the heat induction coil 103 in the cover mechanism 100 to expand rapidly, lift the relay ring 104 upward, and the relay ring 104 pushes the thrust frame 105 to turn outward. The thrust frame 105 that turns outward pushes the force bearing seat 107 outward, and the buckle pin 106 is then pushed into the buckle pin hole at the open part of the casting ladle barrel 041 and is stopped by the ratchet 112. The cover mechanism 100 covering the casting ladle barrel 041 is automatically locked and fixed; at the same time, under the action of heat, the damping oil groove 111 The wax oil inside melts (the wax oil can also be other media that can be converted from solid to liquid under temperature changes), and the wax oil that has gained fluidity is injected into the oil cavity of the oil drain cavity 110 through the oil leakage hole, and the wax oil level drops. The oil drain cavity 110 is pressed downward together with the inverted rounded table 108 under the pressure of the large compression spring 109, and the conical surface of the inverted rounded table 108 is pressed on the inclined surface of the force-bearing seat 107, and the force-bearing seat 107 is moved outward again, and the buckle pin 106 is pushed out again and stopped by the ratchet 112. At this time, the casting package cylinder 041 is sealed and covered by the capping mechanism 100;

[0048] Then the turret assembly 032 is turned over, and the casting mechanism 04 is turned over by the turret assembly 032 to lie flat, and the molten iron receiving position of the casting ladle barrel 041 and the guide pipe 037 is slightly adjusted, and the adjustment motor 036 is started, and the roller at the contact end of the fixed holder 035 rotates, driving the casting mechanism 04 to turn the outlet 042 to face vertically downward (see Figure 8-9 ), the molten iron flows out and is injected into the mold 002 through the guide pipe of the guide pipe 037. After the individual casting is completed, the adjustment motor 036 is started, the roller built in the fixed holder 035 rotates, and the casting mechanism 04 is driven to turn the outlet 042 to be vertically upward, and the translation flip frame 03 sends the casting mechanism 04 to the next station, and the next casting cycle is started;

[0049] When the molten iron in the casting ladle cylinder 041 is consumed to be insufficient for casting a mold, the turret assembly 032 is flipped over, the casting mechanism 04 is erected, the robot arm 02 is moved above the casting mechanism 04, and the robot assembly 023 is lowered directly above the shaft handle head 126, grasps the large nut 125, and unscrews the large nut 125 upward, the large compression spring 109 pushes the ring seat 124 upward, the pull rod 122 pulls the eccentric wheel 120 to rotate, the push plate 117 moves downward, the ratchet 112 is lifted up and pressed down, the claw tip is lifted, the buckle pin 106 is eliminated, and under the action of the spring 121, the buckle pin 106 is reset, the capping mechanism 100 is unlocked, and the robot assembly 023 retracts to the shaft handle head 126, grasps the shaft handle head 126 to lift and move the capping mechanism 100 as a whole, and the next molten iron transfer cycle starts.

[0050] It should be noted that once the temperature of the capping mechanism 100 is used, it cannot drop, the thermal induction coil 103 cannot be restored immediately, and the wax oil cannot lose its fluidity immediately. In order not to affect the production efficiency, two or more robot arms 02 can be installed, and two or more capping mechanisms 100 can be equipped at the same time for alternating use; or an exchange table can be set at the edge, and multiple capping mechanisms 100 can be configured on the exchange table for alternating use.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
