Description

Technical Field

[0001] This utility model relates to the field of pyrometallurgical equipment technology, specifically to a high-temperature lead column manual handling device. Background Technology

[0002] Currently, in addition to the common No. 1 electrolytic lead ingots, some customers require customized lead pillars to reduce environmental hazards and reprocessing costs. Orders for these products are typically small, and due to cost considerations, companies often use manual methods for handling and stacking. In one company's lead pillar production task, each pillar weighed approximately 12kg, and its surface temperature exceeded 100℃ upon demolding. The existing workflow is as follows: molten lead is poured into the mold, cooled and solidified, and then removed from the mold. Operators, wearing high-temperature resistant gloves, directly handle the lead pillars and place them into finished product containers. During the handling of the lead pillars, workers' palms directly contact the high-temperature lead pillars. Even with heat-resistant gloves, there is still a risk of burns to the workers' hands, and their fingers are easily pinched during the placement of the pillars.

[0003] Therefore, there is an urgent need for a special handling fixture for high-temperature lead columns that is simple in structure, easy to operate, and safe and reliable, in order to improve operational safety and human-machine efficiency. Utility Model Content

[0004] The main objective of this invention is to provide a high-temperature lead column manual handling device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a high-temperature lead column manual handling device, comprising: The clamping assembly includes a force-bearing rod and two sets of grippers that are rotatably and oppositely disposed on the force-bearing rod; the force-bearing rod is detachably provided with a handle, and a space is left between the two sets of grippers to form a clamping space; The control assembly includes a control component slidably mounted on a force-bearing rod, and force-transmitting components hinged to the control component and the grippers respectively; a spring-loaded component is provided between the control component and the handle; the force-transmitting component is inclined relative to the force-bearing rod, and the extended axis of the force-transmitting component intersects the extended axis of the force-bearing rod; under the action of an external force along the axial direction of the force-bearing rod, the force-transmitting component drives the two sets of grippers to move towards each other to close or move in opposite directions to separate.

[0006] As a further improvement of this utility model, one end of the force-bearing rod is provided with a rotating shaft; the gripper has an arc-shaped structure and a connecting sleeve is provided on the gripper; the connecting sleeve is rotatably connected to the rotating shaft.

[0007] As a further improvement of this utility model, there is a gap between the connecting sleeves on the two sets of grippers so that the rear ends of the two sets of grippers face each other when they are closed.

[0008] As a further improvement of this utility model, the end of the force-bearing rod away from the rotating shaft is provided with a connecting screw hole; the handle is provided with a connecting stud that mates with the connecting screw hole.

[0009] As a further improvement of this utility model, the control component includes an opening and closing handle slidably disposed on the force-bearing rod, a locking nut and an adjusting nut movably disposed on the force-bearing rod; the opening and closing handle is located between the locking nut and the adjusting nut; the locking nut is disposed near the handle; and the adjusting nut is disposed near the rotating shaft.

[0010] As a further improvement of this utility model, the force transmission component includes two sets of force transmission rods respectively hinged to the opening and closing handle and the gripper, and the distance between the ends of the two sets of force transmission rods connected to the opening and closing handle is less than the distance between the ends of the two sets of force transmission rods connected to the gripper.

[0011] As a further improvement of this utility model, the rebound component includes a rebound spring; the rebound spring is sleeved on the force-bearing rod and located between the opening / closing handle and the locking nut.

[0012] The beneficial effects of this utility model are reflected in: By setting up control components, the two sets of grippers connected to the force rod can be controlled to move towards each other to clamp the lead column or move in the opposite direction to separate and release the lead column. During the clamping process, with the cooperation of the spring mechanism and the force transmission mechanism, the spring mechanism pushes the force transmission rod to apply pressure to the two sets of grippers, causing the two sets of grippers to close. At the same time, under the gravity of the lead column, a vertical downward force is applied to the two sets of grippers, so that the two sets of grippers close and stably clamp the lead column. During the handling of the lead column, workers' palms are prevented from directly contacting the lead column and causing burns. At the same time, during the release of the lead column, workers' fingers are prevented from being pinched by the lead column. Attached Figure Description

Unless otherwise specified, the embodiments and features described in this application can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0015] In one embodiment, see Figure 1 This utility model discloses a high-temperature lead column manual handling device, which includes a clamping component and a control component.

[0016] The clamping assembly includes a force-bearing rod 1 and two sets of grippers 2 rotatably and oppositely disposed on the force-bearing rod 1. A handle 3 is detachably disposed on the force-bearing rod 1, and a space is left between the two sets of grippers 2 to form a clamping space 4. The control assembly includes a control component 5 slidably disposed on the force-bearing rod 1 and a force transmission component 6 that is hinged to the control component 5 and the grippers 2 respectively. A spring-loaded component 7 is disposed between the control component 5 and the handle 3. The force transmission component 6 is inclined relative to the force-bearing rod 1, and the extended axis of the force transmission component 6 intersects the extended axis of the force-bearing rod 1. Under the action of an external force along the axial direction of the force-bearing rod 1, the force transmission component 6 drives the two sets of grippers 2 to move towards each other to close or move in opposite directions to separate.

[0017] Furthermore, one end of the force-bearing rod 1 is provided with a rotating shaft 8, the gripper 2 has an arc-shaped structure, and a connecting sleeve 9 is provided on the gripper 2, which is rotatably connected to the rotating shaft 8.

[0018] Preferably, a bushing 10 is welded to the end of the force-bearing rod 1, and the rotating shaft 8 is located at both ends of the bushing 10.

[0019] Preferably, the connecting sleeve 9 is a hollow ring, and the connecting sleeve 9 on the two sets of grippers 2 is rotatably sleeved on the rotating shafts 8 at both ends of the bushing 10.

[0020] Furthermore, there is a gap between the connecting sleeves 9 on the two sets of grippers 2 so that the rear ends of the two sets of grippers 2 face each other when they are closed.

[0021] Preferably, the two sets of grippers 2 are hollow circular rings cut to form a left clamping plate and a right clamping plate. The left clamping plate and the right clamping plate are made of stainless steel tubes with an inner diameter smaller than the diameter of the lead column to be clamped. The stainless steel tubes are split in half along the axial direction, and an arc segment of about 5° is cut off from each of the two halves of the tube to form the main structure of the left clamping plate and the right clamping plate, so as to enhance the contact area and stability during clamping. The connecting sleeve 9 is welded to the top of the left clamping plate and the right clamping plate.

[0022] Preferably, the inner walls of both the left and right clamping plates are provided with anti-slip textures 19 to improve clamping friction.

[0023] Preferably, the width of the left and right clamps is between 3cm and 5cm, which can increase the contact area with the lead column and make the clamping of the lead column more stable.

[0024] Furthermore, the end of the force-bearing rod 1 away from the rotating shaft 8 is provided with a connecting screw hole 11, and the handle 3 is provided with a connecting stud 12 that mates with the connecting screw hole 11.

[0025] Preferably, the connecting screw hole 11 is located at the center of the end of the force-bearing rod 1, and the connecting stud 12 is located at the center of the handle 3. After the connecting stud 12 is threadedly connected to the connecting screw hole 11, the axis of the force-bearing rod 1 is perpendicular to the axis of the handle 3.

[0026] Preferably, the surface of the handle 3 is covered with a heat-insulating layer made of rubber to improve operating comfort and safety.

[0027] Furthermore, the control component 5 includes an opening and closing handle 501 slidably disposed on the force-bearing rod 1, a locking nut 502 movably disposed on the force-bearing rod 1, and an adjusting nut 503. The opening and closing handle 501 is located between the locking nut 502 and the adjusting nut 503. The locking nut 502 is disposed near the handle 3, and the adjusting nut 503 is disposed near the rotating shaft 8.

[0028] Preferably, the opening and closing handle 501 is provided with a mounting groove 504, and the force-bearing rod 1 passes through the mounting groove 504 so that the opening and closing handle 501 is movably connected with the force-bearing rod 1.

[0029] Preferably, the outer wall of the force-bearing rod 1 is provided with threads that are threaded to the locking nut 502 and the adjusting nut 503 respectively. After the handle 3 is connected to the force-bearing rod 1, the locking nut 502 can be rotated to abut against the handle 3 to prevent the handle 3 from becoming loose.

[0030] Furthermore, the force transmission component 6 includes two sets of force transmission rods that are respectively hinged to the opening / closing handle 501 and the gripper 2. The distance between the ends of the two sets of force transmission rods connected to the opening / closing handle 501 is less than the distance between the ends of the two sets of force transmission rods connected to the gripper 2.

[0031] Preferably, the opening and closing handle 501 is provided with a first ear plate 13, the first ear plate 13 is provided with a first rotating hole 14, the gripper 2 is provided with a second ear plate 15, and the second ear plate 15 is provided with a second rotating hole 16.

[0032] Preferably, the two ends of the force transmission rod are respectively provided with a first hinge shaft 17 and a second hinge shaft 18, the first hinge shaft 17 is rotatably connected to the first rotating hole 14, and the second hinge shaft 18 is rotatably connected to the second rotating hole 16.

[0033] Furthermore, the spring-loaded component 7 includes a spring-loaded spring, which is sleeved on the force-bearing rod 1 and located between the opening / closing handle 501 and the locking nut 502.

[0034] Preferably, the rebound spring has an existing structure. The distance between the adjusting screw and the locking screw can be adjusted by rotating the adjusting screw, which can control the preload of the rebound spring. In turn, the distance between the opening and closing handle 501 and the handle 3 can be adjusted. The handle 3, the locking nut 502 and the force rod 1 are detachably connected, which makes it easy to replace the rebound spring.

[0035] Assembly process: First, screw the adjusting nut 503 into the force-bearing rod 1, then install the opening / closing handle 501 and the return spring in sequence. Next, screw the locking nut 502 onto the top of the force-bearing rod 1, screw the handle 3 into the connecting screw hole 11 at the fixed part of the force-bearing rod 1, and tighten the locking nut 502 to prevent the handle 3 from loosening during operation. Then, connect the left and right clamping plates to the rotating shaft 8 on the force-bearing rod 1 via the connecting sleeve 9, hinged together. At this point, the left and right clamping plates can swing freely around the rotating shaft 8. Finally, hinge both ends of the force transmission rod to the connection points of the opening / closing handle 501, the left clamping plate, and the right clamping plate, respectively; thus, the entire device assembly is complete.

[0036] Working principle and usage: In its natural state, the spring force of the return spring presses downward on the opening and closing handle 501. The opening and closing handle 501, through two sets of force rods 1, applies an inward pressure to the upper part of the left and right clamping plates respectively. This pressure causes the lower part of the left and right clamping plates, i.e., the clamping end, to retract towards the center around the pivot 8, entering a normally closed clamping state. When it is necessary to clamp a high-temperature lead column, the operator holds the handle 3 with one hand and hooks the opening and closing handle 501 upward with the middle and index fingers, overcoming the spring force of the return spring and moving it upward. Through the force rods 1, the top of the left and right clamping plates is pulled outward, thus opening the lower part of the clamping plates. After the opened jaws 2 are placed over the lead column, the operator releases the opening and closing handle 501. Under the restoring force of the return spring, the opening and closing handle 501 moves downward and, through the force transmission rod, drives the left and right clamping plates to close, tightly holding the lead column. At this point, the operator can safely lift and transport the lead column. During lifting, the left and right clamps, under the force of the return spring and the weight of the lead column (the weight of the lead column is downward, the force applied to the clamps 2 is downward, and the return spring causes the two sets of clamps 2 to close), firmly hold the lead column. When transporting it to the container, pull up the opening handle 501 again; the left and right clamps will open, releasing the lead column.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
