[0002] During the calcium carbide tapping process, frequent transfer of the calcium carbide pot and demolding operations are required. This typically necessitates the use of two different lifting devices, each operated by a crane, resulting in low work efficiency. Existing calcium carbide pots, such as those with attached... Figure 2 As shown, the calcium carbide pot has openable and closable templates on both sides, and the liquid calcium carbide in the pot is cooled into calcium carbide lumps; Patent document CN223032863U discloses a single and double clamp for pulling calcium carbide lumps. During the pulling stage of calcium carbide lumps, the single clamp needs to be manually released to a low position and then the calcium carbide lumps are held by their own weight. Moreover, due to the limitations of the structural layout, the clamping force of the single clamp is poor, making it difficult to maintain the reliability of pulling lumps of ton-sized calcium carbide lumps. Utility Model Content

[0003] To address the low automation and poor reliability of existing calcium carbide pot transfer and calcium carbide lumps extraction processes, this invention proposes a fully automatic integrated pot clamping and lumps extraction lifting device. It includes a hanger, the upper end of which is mounted on an external lifting and conveying device. A linear drive mechanism is located at the center of the hanger, and its end is hinged to a scissor-type lumps extraction clamping mechanism. The linear drive mechanism drives the lumps extraction clamping mechanism to swing inward and outward, clamping the calcium carbide lumps when swinging inward. Symmetrical pot clamping mechanisms are located on both sides of the lumps extraction clamping mechanism. Each pot clamping mechanism includes two sets of scissor-type clamping mechanisms, the upper ends of which are pivotally hinged to a connecting frame. When the lower opening of the scissor-type clamping mechanism decreases, it can... The device clamps a calcium carbide pot. Two sets of scissor clamping mechanisms are connected by a through shaft. One side of each scissor clamping mechanism is equipped with a clamping locking mechanism, which includes a ridge-shaped buckle. The lower end of the buckle is connected to the through shaft. Two sets of guide flaps are symmetrically hinged in the middle of the buckle. When the guide flaps are in the upper position, they abut against the outermost side of the buckle. Two sets of hooks are symmetrically arranged on both sides of the buckle. The hook heads of the two sets of hooks can wedge into the sides of the buckle respectively. The upper ends of the hooks are hinged to a connecting frame. When the hook heads are below the guide flaps, the opening of the scissor clamping mechanism is at its maximum. As the hooks rise relative to the buckle, the opening of the scissor clamping mechanism gradually decreases. When the hook heads are hooked on both sides of the buckle, the lower opening of the scissor clamping mechanism can be locked.

[0004] The pulling and clamping mechanism includes a limiting rod, a pair of connecting rods, and a pair of clamping plates. The upper end of the limiting rod is hinged to the output shaft end of the drive mechanism. The lower ends of the limiting rod are respectively hinged to the heads of the two connecting rods. The tails of the connecting rods are respectively hinged to the heads of the two clamping plates. The upper parts of the two clamping plates are cross-shaped and hinged. The extension and retraction of the end of the linear drive mechanism realizes the opening and closing action of the clamping plates.

[0005] The lower part of the clamping plate is hinged to the upper end of the positioning stop, and the lowest end of the positioning stop is lower than the lowest end of the clamping plate.

[0006] The limiting tie rod and the two connecting rods are provided with an outwardly extending guide shaft at the hinge joint, which moves in the corresponding guide groove provided on the hanger when it is raised or lowered.

[0007] The linear drive mechanism is equipped with an identification and positioning mark above it, which is used to identify the position of the hanger and send it to the control system. The control system dynamically adjusts the movement of the external lifting and transferring device according to its posture information.

[0008] The scissor clamping mechanism includes a pair of connecting arms and a pair of clamping arms. The heads of the two connecting arms are hinged together on the connecting frame, and the tails of the connecting arms are respectively hinged to the heads of the two clamping arms. The upper parts of the two clamping arms are crossed and hinged together.

[0009] The through shaft is located at the cross hinge point on the upper part of the two clamping arms.

[0010] The beneficial effects of this utility model are: A. A lifting and clamping mechanism and a pot clamping mechanism are installed on a single hanger. When lifting the carbide, the pot clamping mechanism is locked and does not affect the lifting operation. When clamping the carbide, the lifting and clamping mechanism can automatically open without affecting the clamping operation. The scissor clamping mechanism descends when the opening is locked to avoid manual intervention. The clamping and locking mechanism can automatically unlock the scissor clamping mechanism to ensure automated pot clamping and synchronization. The integrated layout of this mechanism can not only cooperate to improve the degree of automation, but also improve work efficiency and further enhance the reliability of the equipment during operation.

[0011] B. By utilizing the cooperation between the clamping and locking mechanism and the scissor clamping mechanism, the opening of the two clamping arms of the scissor clamping mechanism can be automatically locked before the calcium carbide pot is lowered to clamp it. This allows the clamping arms to accurately touch the upper edge of the calcium carbide pot. After touching the calcium carbide pot, the scissor clamping mechanism is lowered to its maximum opening when the hook head is below the guide flap. This ensures the reliability of the scissor clamping mechanism in clamping the calcium carbide pot by its own weight during lifting, and also allows the lower clamping arm of the scissor clamping mechanism to smoothly detach from the calcium carbide pot.

[0012] C. A linear drive mechanism is used to drive the clod-pulling clamping mechanism to achieve swing clamping action. The power clamping improves the stability of the clamping, the success rate of clod pulling, and the degree of automation of clod pulling.

[0013] D. By utilizing the positioning stop bar set at the bottom of the clamping plate, the positioning stop bar can automatically position the clamping block by touching the template before the clamping plate, thereby further improving the reliability of the clamping block.

[0014] E. The linear drive mechanism is equipped with an identification and positioning mark on top, which can send the attitude information of the calcium carbide lifting device in real time and adjust the movement state of the external lifting and transferring device in real time to control the attitude of the lifting device and reduce the degree of swaying during the lifting device transfer process.

[0025] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model are described in detail below with reference to the accompanying drawings. The embodiments are exemplary and intended to explain this utility model, but should not be construed as limiting this utility model.

[0026] The purpose of this invention is to provide a fully automatic integrated lifting device for clamping and pulling pots. See [link / reference]. Figures 1 to 7The calcium carbide pot 8 has openable and closable templates 7 on both sides. The liquid calcium carbide inside the calcium carbide pot 8 is cooled into calcium carbide lumps 6. The invention includes a hanger 1, the upper end of which is mounted on an external lifting and transferring device. A linear drive mechanism 2 is provided at the center of the hanger 1. The end of the linear drive mechanism 2 is hinged to a scissor-type lump-pulling and clamping mechanism 4. The linear drive mechanism 2 drives the lump-pulling and clamping mechanism 4 to swing inward and outward. When swinging inward, it can clamp the calcium carbide lumps 6. The left and right sides of the lump-pulling and clamping mechanism 4 are provided with symmetrical pot clamping mechanisms 5. The pot clamping mechanism 5 includes two sets of scissor-type clamping mechanisms 52. The upper end of the scissor-type clamping mechanism 52 is pivotally hinged to a connecting frame 51. When the lower opening of the scissor-type clamping mechanism 52 decreases, it can clamp the calcium carbide pot 8. The two sets of scissor-type clamping mechanisms 52 are connected by a through shaft 55. The through shaft 55 is located at the cross hinge point on the upper part of the two clamping arms 522. A clamping and locking mechanism 53 is provided on one side of the scissor clamping mechanism 52. The clamping and locking mechanism 53 includes a ridge-shaped buckle 531. The lower end of the buckle 531 is connected to the through shaft 55. Two sets of guide flaps 532 are symmetrically hinged in the middle of the buckle 531. When the guide flaps 532 are in the upper position, they abut against the outermost side of the buckle 531. Two sets of hooks 533 are symmetrically provided on both sides of the buckle 531. The hook heads of the two sets of hooks 533 can be wedged with the two sides of the buckle 531 respectively. The upper end of the hooks 533 is hinged to the connecting frame 51. When the hook heads of the hooks 533 are below the guide flaps 532, the opening of the scissor clamping mechanism 52 is at its maximum. As the hooks 533 rise relative to the buckle 531, the opening of the scissor clamping mechanism 52 gradually decreases. When the hook heads of the hooks 533 are hooked on both sides of the buckle 531, the lower opening of the scissor clamping mechanism 52 can be locked. In some embodiments, the external lifting and transferring device is an overhead crane, preferably an intelligent unmanned overhead crane, and the linear drive mechanism 2 is preferably a combination of a motor and a telescopic mechanism, but it is not limited to this and can also be an electric cylinder, a hydraulic cylinder, or other power source drive structure.

[0027] Furthermore, the pulling and clamping mechanism 4 includes a limiting rod 41, a pair of connecting rods 42, and a pair of clamping plates 43. The upper end of the limiting rod 41 is hinged to the output shaft end of the drive mechanism 2, and the lower ends of the limiting rod 41 are respectively hinged to the heads of the two connecting rods 42. The tails of the connecting rods 42 are respectively hinged to the heads of the two clamping plates 43. The upper parts of the two clamping plates 43 are cross-shaped and hinged. The extension and retraction of the end of the linear drive mechanism 2 realizes the opening and closing action of the clamping plates 43.

[0028] Furthermore, the lower part of the clamping plate 43 is hinged to the upper end of the positioning stop 44, and the lowest end of the positioning stop 44 is lower than the lowest end of the clamping plate 43; during the descent, the positioning stop 44 can touch the template 7 before the clamping plate 43 to automatically position the clamping block, further improving the reliability of the clamping block.

[0029] Furthermore, the hinge joint between the limiting rod 41 and the two connecting rods 42 is provided with an outwardly extending guide shaft 45, which moves in the corresponding guide groove provided on the hanger 1 during lifting and lowering, ensuring stability and reliability during lifting and lowering.

[0030] Furthermore, an identification and positioning mark 3 is provided above the linear drive mechanism 2 to identify the position of the hanger 1 and send it to the control system. The control system dynamically adjusts the movement of the external lifting and transferring device according to its posture information. It can send the posture information of the calcium carbide lifting device in real time and adjust the movement state of the external lifting and transferring device in real time to control the posture of the lifting device and reduce the degree of swaying during the lifting device transfer process.

[0031] Furthermore, the scissor clamping mechanism 52 includes a pair of connecting arms 521 and a pair of clamping arms 522. The heads of the two connecting arms 521 are hinged together on the connecting frame 51, and the tails of the connecting arms 521 are respectively hinged to the heads of the two clamping arms 522. The upper parts of the two clamping arms 522 are arranged crosswise and hinged.

[0032] See Figures 1-10 The working principle of this embodiment is explained as follows: The calcium carbide pot 8: With the templates 7 on both sides of the calcium carbide pot 8 in the closed state, the linear drive mechanism 2 drives the clamping mechanism 4 to open the clamping plate 43 to its maximum extent. Figure 4 As shown, at this time, the hook head of the hook 533 is hooked onto the buckle 531; after receiving the instruction to pull out the calcium carbide pot 8, the external lifting and transferring device, based on the position information of the calcium carbide pot 8, drives the calcium carbide lifting device to a suitable position above the calcium carbide pot 8, and continues to descend so that the clamping arms 522 contact the upper edge of the calcium carbide pot 8 respectively. The hook head of the hook 533 slides down along the guide flap 532, further increasing the opening of the clamping arms 522, as shown. Figure 5 As shown; the lifting and transferring device is lifted upwards, and under the action of gravity, the opening of the scissor clamping mechanism 52 gradually decreases. During this process, the hook head of the hook 533 flips the guide plate 532 upwards and slides out of the buckle 531, as shown. Figure 6 As shown; the guide flap 532 returns to its original position under the action of gravity, while the hook 533 continues to move upward and disengage from the latch 531 for a certain distance, allowing the opening of the two clamping arms 522 to clamp the calcium carbide pot 8 and lift the calcium carbide pot 8 to a certain height, as shown. Figure 7 , Figure 8 As shown; like Figure 9As shown, after the calcium carbide pot 8 is transferred to the designated position, it is lowered. The lifting and transferring device continues to drive the scissor clamping mechanism 52 to descend, so that the opening of the two clamping arms 522 gradually increases. The hook 533 approaches the buckle 531 and slides down along the upper inclined surface of the buckle 531 until the hook head of the hook 533 hooks onto both sides of the buckle 531 and locks the two clamping arms 522 in the open state. At this time, during the process of the lifting and transferring device lifting upward, the two clamping arms 522 always remain at the locked opening so that they can move away from the calcium carbide pot 8 smoothly and continue to perform the next clamping action of the calcium carbide pot 8.

[0033] Unplugging Stone Pile 6: As Figure 10 As shown, calcium carbide is cooled in the calcium carbide pot 8 to the time when it can be pulled out, and the templates 7 on both sides of the calcium carbide pot 8 are in the open state. After receiving the instruction to pull out the calcium carbide lump 6, the external lifting and transferring device drives the calcium carbide lifting device to a predetermined height position above the calcium carbide pot 8 according to the position information of the calcium carbide pot 8. It continues to drive the calcium carbide lifting device to move horizontally along the length direction of the calcium carbide pot 8, so that the positioning stop bar 44 contacts the template 7 and sends a positioning signal. The end of the linear drive mechanism 2 retracts to clamp the calcium carbide lump 6 with the two clamps 43. The external lifting and transferring device drives the calcium carbide lifting device to lift upward, pull out the calcium carbide lump 6 as a whole from the calcium carbide pot 8 and transfer it to the designated position. After that, the calcium carbide lump 6 is lowered. The end of the linear drive mechanism 2 extends to release the calcium carbide lump 6 with the two clamps 43, completing the lump pulling action.
