Limiting plates 19 are arranged at two ends of the sliding rail 16 to limit the sliding bracket 17 from being separated from the sliding rail 16 when moving; each side of the I-steel 11 is provided with a hole lug 18 at the upper and lower parts; the I-steel 11 is more stable when the spring 13 is pressed down along the guide rod 12; kong Er 18 are outwardly convex so that when the spool 11 is moved downwardly to support the gate, the spool 11 eventually falls onto the base surface between the two rails 16 to support the gate; the spring 13 is compressed at this time, but not so much as to fail in overpressure; the spring 13 enables the I-steel 11 to be separated from the base surface when not bearing the gate pressure, the I-steel 11 is suspended, and the self weight is transmitted to the sliding brackets 17 on the two sides through the spring 13; the lower part of the sliding support 17 is provided with a pulley 15 capable of moving left and right along the sliding rail 16, and two pulleys 15 can be arranged below each sliding support 17, so that the friction force of the I-steel 11 is smaller; the sliding support 17 is an A-frame, the guide rod 12 is overlapped with the height on the bottom edge of the A-frame, and the overall weight of the ingot locking mechanism is further reduced on the premise of ensuring the stable structure.
As shown in fig. 2. The control mechanism 2 comprises a push rod 21 fixedly connected with the connecting frame 14, a pull rod 22 hinged with the push rod 21, a crankshaft 23 hinged with the pull rod 22, a large gear 24 fixed on the crankshaft 23, a small gear 25 meshed with the large gear 24 and a control motor 26 for driving the small gear 25 to rotate; the crankshaft 23 includes a central shaft 27 and a bell crank 28; the central shaft 27 is coaxial with the large gear 24; the tie rod 22 is hinged to a bell crank 28 of the crankshaft 23. The control motor 26 can adopt well-known wired electric connection control or wireless control, and the control motor 26 drives the pinion 25 to drive the large gear 24 to rotate so as to realize accurate angle rotation; the large gear 24 rotates to drive the crankshaft 23 to rotate; when the crank throw 28 rotates to the leftmost side, the push rod 21 and the pull rod 22 are on the same horizontal line, and the state is in a full unlocking state; when the crank 28 rotates to the rightmost side, the push rod 21 and the pull rod 22 return to the same horizontal line again, and the state is a full throw-lock ingot state; in the full state of withdrawal and full state of throw-lock, since the push rod 21 and the pull rod 22 are on the same horizontal line, the slide bracket 17 is hardly moved left and right by external disturbance, and is finally received on the support housings on both sides of the crankshaft 23 because the push-pull force passes through the center shaft 27.
As shown in fig. 3. The control mechanism 2 further comprises an upper baffle 3 and a lower baffle 4; the upper baffle plate 3 and the lower baffle plate 4 are respectively provided with a torsion spring 5 and a weight 6 which enable the upper baffle plate and the lower baffle plate to automatically reset after rotating, and the outer sides of the upper baffle plate and the lower baffle plate are provided with inclined planes 7; when the crank throw 28 of the crankshaft 23 rotates to the leftmost horizontal position and then continues to rotate, the torsion spring 5 on the upper baffle 3 or the lower baffle 4 is compressed. When the crank throw 28 rotates to the leftmost horizontal position, the crank throw 28 is in a full state of withdrawal of the lock ingot, the control motor 26 does not need to apply force to keep against external interference, and the crank throw 28 can be stably positioned between the upper baffle 3 and the lower baffle 4 to keep the stability of the full state of withdrawal of the lock ingot. When the crank throw 28 rotates from top to bottom to the upper baffle plate 3 or from bottom to top to the lower baffle plate 4, the crank throw 28 can press on the inclined plane 7 to enable the upper baffle plate 3 or the lower baffle plate 4 to rotate around a fixed point, at the moment, the crank throw 28 can easily rotate between the upper baffle plate 3 and the lower baffle plate 4 only by overcoming the torque generated by the weight 6, but when the crank throw 28 leaves from between the upper baffle plate 3 and the lower baffle plate 4, the torque of the torsion spring 5 must be overcome, and because the push rod 21 and the pull rod 22 are on the same horizontal line, the crank throw 28 is hard to rotate due to the fact that the sliding bracket 17 moves left and right under the external force, and therefore the stability of the complete state of unlocking ingots is ensured.

The invention also comprises a buffer mechanism 8, wherein the buffer mechanism 8 is arranged in a lower basal plane when the I-steel 11 is positioned at the rightmost side; the buffer mechanism 8 includes a housing 81, a bearing portion 82, a guide portion 83, and a return spring 84; a guide part 83 is fixed below the bearing part 82, the guide part 83 is inserted into the housing 81, and the upper edge of the housing 81 can support the bearing part 82; a return spring 84 for supporting the bearing part 82 is arranged in the shell 81, and an exhaust small hole 85 is arranged on the shell; the carrier 82 is not under pressure, and the return spring 84 keeps the carrier 82 flush with the base surface. When the i-beam 11 is located at the rightmost side, the gate falls down to press the i-beam 11, the i-beam 11 falls down to press the bearing portion 82, the bearing portion 82 sinks down from a plane with the base surface, and finally the bearing portion 82 is supported at the upper edge of the housing 81. The housing is provided with the small vent holes 85, so that the bearing part 82 can buffer the I-steel 11 in the sinking process, the I-steel 11 finally sinks on a concave part of the base surface when being subjected to gate pressure, and the concave part enables the I-steel 11 not to move left and right, so that the bearing gate is stable. When the I-steel 11 is not stressed, the spring 13 makes the I-steel 11 separate from the base surface, the I-steel 11 is suspended, and the bearing part 82 is restored to the same plane with the base surface under the action of the return spring 84.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structures or equivalent processes using the descriptions and drawings of the present invention or directly or indirectly applied to other related technical fields are included in the scope of the invention.
