Description

Technical Field

[0001] The invention belongs to the technical field of hanging conveyor lines, in particular to a lifting mechanism for hanging and conveying a pouring bucket. Background Art

[0002] Cylinder liner is the abbreviation of cylinder liner. It is embedded in the cylinder barrel of the cylinder body and forms a combustion chamber together with the piston and cylinder head. Cylinder liner is divided into two categories: dry cylinder liner and wet cylinder liner. The cylinder liner whose back does not contact the cooling water is called dry cylinder liner, and the cylinder liner whose back contacts the cooling water is wet cylinder liner. The dry cylinder liner is thin, simple in structure and easy to process. The wet cylinder liner directly contacts the cooling water, so it is beneficial to the cooling of the engine and the compactness and lightness of the engine.

[0003] During the production of cylinder liners, a pouring process is required. During the pouring process of the cylinder liners, the pouring bucket needs to be transported to the centrifugal casting machine, and the molten iron is poured into the centrifugal casting machine for centrifugal casting. In this process, a hanging assembly line is required. During the use of the hanging assembly line, the pouring bucket needs to be hung on a hook, and with the help of a steel rope, the crane is started to lift the pouring bucket from the ground to a certain height, so that the pouring bucket can be transported in the air. First, during the process of the crane lifting the pouring bucket, if the crane lifting speed is too fast, the pouring bucket is prone to shaking. And if the pouring bucket is affected by external forces (such as wind, accidental collision, etc.) when it is lifted, the force on the pouring bucket is unstable, which can also cause the pouring bucket to shake during the lifting process, or the workers Due to improper operation, when the crane lifts the pouring bucket, the hanging assembly line is started, making the hanging assembly line in a moving state. At this time, the pouring bucket makes a curved motion under the combination of vertical and horizontal motion, which inevitably causes the pouring bucket to shake; secondly, during the movement of the hanging assembly line, the slide rail and pulley are currently adopted, which have poor stability. The long-term dust accumulation will cause poor sliding, or the assembly line will suddenly stop during the movement. At this time, the pouring bucket is affected by inertia, causing the pouring bucket to shake. In summary, whether it is during the lifting or walking of the hanging assembly line, the pouring bucket may shake, which increases the probability of the molten iron in the pouring bucket overflowing and the pouring bucket falling off, making the pouring bucket unstable and affecting the safety factor.

[0004] In view of this, the present invention solves the above technical problems by proposing a lifting mechanism for hanging and conveying a pouring bucket. Summary of the invention

DETAILED DESCRIPTION

[0037] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0038] like Figures 1 to 5 As shown, the lifting mechanism for hanging and conveying a pouring bucket described in the present invention comprises:

[0039] Slide rail 1;

[0040] A suspension rod 2, the top of which is rotatably connected to a pulley;

[0041] A connecting block 3, the bottom of the suspension rod 2 is fixedly connected with the connecting block 3;

[0042] A control box 4, which is divided into two parts a and b and both are fixedly connected to the bottom of the connection block 3;

[0043] Block No. 1 5, the block No. 1 5 is divided into two parts c and d, and the block No. 1 5 is fixedly connected to the bottom of the control box 4;

[0044] No. 1 motor 6, the No. 1 motor 6 is fixedly connected to one side of the No. 1 block 5, a brake mechanism is provided in the No. 1 block 5, and the output shaft of the No. 1 motor 6 is fixedly connected to a winding shaft 61;

[0045] A traction rope 7, one end of which is fixedly connected to the bottom of the No. 1 block 5, a movable pulley 71 is movably provided below the No. 1 block 5, a hook 72 is provided at the bottom of the movable pulley 71, and the traction rope 7 passes through the movable pulley 71 and the other end of which is fixedly connected to the winding shaft 61;

[0046] A stabilizing mechanism 8 is provided, wherein a cavity 81 is formed between parts a and b of the control box 4 and parts c and d of block 1 5, and a stabilizing mechanism 8 is movably arranged in the cavity 81. The stabilizing mechanism 8 ensures the stability of the pouring bucket during the lifting and transportation process by clamping the pouring bucket and moving with the pouring bucket.

[0047] During operation, during the pouring of the cylinder sleeve, the pouring bucket needs to be transported to the centrifugal casting machine, and the molten iron is poured into the centrifugal casting machine for centrifugal casting; in this process, a hanging assembly line is needed. During the use of the hanging assembly line, the pouring bucket needs to be hung on the hook 72, and the pouring bucket is lifted from the ground to a certain height under the action of the steel rope, so that the pouring bucket can be transported in the air; first, during the process of the crane lifting the pouring bucket, if the crane lifting speed is too fast, the pouring bucket is prone to shaking; and if the pouring bucket is affected by external forces (such as wind force, accidental collision by humans, etc.) when it is lifted, the force on the pouring bucket is unstable, which may also cause the pouring bucket to shake during the lifting process, or improper operation by workers, When the crane lifts the pouring bucket, the hanging assembly line is started, so that the hanging assembly line is in a walking state. At this time, the pouring bucket makes a curved motion under the combination of vertical and horizontal motions, which will inevitably cause the pouring bucket to shake; secondly, during the walking process of the hanging assembly line, the slide rail 1 is currently adopted in combination with a pulley, which has poor stability. The long-term accumulation of dust will cause poor sliding, or the assembly line will suddenly stop during the walking process. At this time, the pouring bucket is affected by inertia, causing the pouring bucket to shake. In summary, whether it is during the lifting or walking process of the hanging assembly line, the pouring bucket may shake, thereby increasing the probability of the molten iron in the pouring bucket overflowing and the pouring bucket falling off, making the pouring bucket unstable and affecting the safety factor;

[0048] When the present application is in use, the pouring bucket is first hung on the hook 72, and the No. 1 motor 6 is started to rotate the winding shaft 61. One end of the traction rope 7 is fixedly connected to the bottom of the c part of the No. 1 block 5, and the other end is fixedly connected to the winding shaft 61. Therefore, the rotation of the winding shaft 61 can wind the traction rope 7 around the winding shaft 61 to realize the lifting of the pouring bucket. In addition, the hook 72 and the traction rope 7 adopt the movable pulley 71 structure, which has a labor-saving effect; a brake mechanism is provided in the No. 1 block 5 to limit the rotation of the output shaft of the No. 1 motor 6 under the action of the gravity of the pouring bucket after the pouring bucket is lifted, so as to prevent the pouring bucket from falling to the ground with the hook 72 under the action of gravity when the crane stops working; then the pulley cooperates with the slide rail 1 to realize the transportation of the pouring bucket; in this process, a stabilizing mechanism 8 is movably provided in the cavity 81, and the stabilizing mechanism 8 ensures the stability of the pouring bucket during the lifting and transportation process by clamping the pouring bucket and following the pouring bucket to move together, so as to improve the safety factor;

[0049] It should be noted that the brake mechanism, pulley and slide rail 1 used in the present application are consistent with the structure and principle of the prior art.

[0050] As a specific embodiment of the present invention, the stabilizing mechanism 8 includes:

[0051] A rotating disk 82, the rotating disk 82 is located in the cavity 81 and is rotatably connected to the side wall of the control box 4, and there are two rotating disks 82;

[0052] Clamping rods 83, two of which penetrate the rotating disk 82 and are slidably connected to the rotating disk 82;

[0053] The clamping frames 84 are two and both are fixedly connected to the clamping rod 83 near the bottom.

[0054] As a specific embodiment of the present invention, the turntable 82 is provided with latch teeth 821 on a side of the control box 4, close to the turntable 82, and the latch teeth 821 are engaged with each other; a drive motor is fixedly provided inside the control box 4, and one of the turntables 82 is fixedly connected to the output shaft of the drive motor.

[0055] During operation, a driving motor is fixedly arranged inside the control box 4, wherein one of the turntables 82 is fixedly connected to the output shaft of the driving motor. The driving motor is a low-speed motor. The driving motor is controlled to rotate so that one of the turntables 82 rotates. Since the turntables 82 are close to the side wall of the control box 4 and the side close to the turntables 82 is provided with latch teeth 821, the latch teeth 821 are meshed with each other, and there are two clamping rods 83 which penetrate the turntables 82 and are slidably connected to the turntables 82, the rotation of the driving motor can drive the two turntables 82 to rotate in the opposite direction, thereby making the clamping rods 83 approach or move away from each other. When the hook 72 lifts the pouring bucket, the driving motor is controlled so that the clamping frame 84 lifts the pouring bucket. The side wall is clamped, and the clamping frame 84 is composed of a semicircular ring, which can adapt to the arc structure of the side wall of the pouring bucket; after the pouring bucket is clamped, the pouring bucket moves up, and since the clamping rods 83 pass through the turntable 82 and are slidably connected to the turntable 82, the pouring bucket can drive the clamping rods 83 to rise together, so that the clamping rods 83 cooperate with the clamping frame 84 to clamp the pouring bucket during the lifting and transportation of the pouring bucket. The clamping rod 83 is a rigid structure, and the clamping rod 83 limits the relative displacement of the clamping rod 83 and the control box 4 and the No. 1 block 5 in the turntable 82. Therefore, this setting can limit the swing of the pouring bucket during lifting and transportation; ensure the stability of the pouring bucket during lifting and transportation.

[0056] As a specific embodiment of the present invention, Figure 3 As shown, the winding shaft 61 is located in the part of the cavity 81 and is fixedly connected to the top side wall of the No. 1 block 5 close to the top side wall and located on the upper left side of the No. 1 gear 85, and is rotatably connected to the No. 2 gear 86, and the No. 1 gear 85 is meshed with the No. 2 gear 86; the No. 1 block 5 is close to the top side wall and located on the upper right side of the No. 1 gear 85 and is rotatably connected to the No. 3 gear 87, and the No. 1 block 5 is close to the top side wall and located on the upper right side of the No. 3 gear 87 and is rotatably connected to the No. 4 gear 88, and the No. 1 gear 85 is meshed with the No. 3 gear 87, and the No. 3 gear 87 is meshed with the No. 4 gear 88; a rack 89 is fixedly provided on one side of the clamping rod 83 close to the No. 1 gear 85.

[0057] As a specific implementation of the present invention, the specifications of the second gear 86, the third gear 87 and the fourth gear 88 are consistent, the pitch circle diameter of the first gear 85 is four times the pitch circle diameter of the second gear 86, the third gear 87 and the fourth gear 88, and the number of teeth of the first gear 85 is twice the number of teeth of the second gear 86, the third gear 87 and the fourth gear 88.

[0058] During operation, when the turntable 82 drives the clamping rod 83 and the clamping frame 84 to clamp the pouring bucket, the clamping rod 83 is just in a vertical state, and the racks 89 on the two clamping rods 83 are respectively meshed with the No. 2 gear 86 and the No. 4 gear 88. When the winding shaft 61 rotates counterclockwise to lift the pouring bucket, the No. 1 gear 85 coaxial with the winding shaft 61 rotates, and the No. 1 gear 85 drives the No. 2 gear 86 to rotate, and the No. 2 gear 86 drives the left clamping rod 83 and makes it move upward. Similarly, the rotation of the No. 1 gear 85 also drives the No. 3 gear 87 to rotate, and the No. 3 gear 87 drives the No. 4 gear 88 to rotate, and the No. 4 gear 88 drives the right clamping rod 83 to move and make it move upward.

[0059] It should be noted that the specifications of the No. 2 gear 86, the No. 3 gear 87 and the No. 4 gear 88 are consistent, the pitch circle diameter of the No. 1 gear 85 is four times the pitch circle diameters of the No. 2 gear 86, the No. 3 gear 87 and the No. 4 gear 88, and the number of teeth of the No. 1 gear 85 is twice the number of teeth of the No. 2 gear 86, the No. 3 gear 87 and the No. 4 gear 88 (the winding shaft 61 is located at the pitch circle position of the No. 1 gear 85, and the position of the winding shaft 61 winding the traction rope 7 is not in the same vertical plane as the position of the No. 1 gear 85, so the winding shaft 61 will not affect the No. 1 gear 85 when winding the traction rope 7), because the hook 72 and the traction rope 7 adopt the movable pulley 71 structure, according to the basic knowledge of the movable pulley 71, the speed at which the winding shaft 61 drives the traction rope 7 to pull the pouring bucket is twice the rising speed of the pouring bucket; according to the gear linear speed formula: ; D: pitch circle diameter, n: rotation speed, and the speed ratio of the gear is equal to the inverse ratio of the number of teeth, so this setting makes the linear speed of the No. 1 gear 85 twice the linear speed of the No. 2 gear 86, the No. 3 gear 87 and the No. 4 gear 88. Since the two clamping rods 83 are tangential to and mesh with the No. 2 gear 86 and the No. 4 gear 88 respectively, the rising speed of the two clamping rods 83 is equal to the linear speed of the No. 2 gear 86 and the No. 4 gear 88. Combined with the fact that the winding shaft 61 is located at the pitch circle position of the No. 1 gear 85, the linear speed of the No. 1 gear 85 is equal to the speed at which the winding shaft 61 drives the traction rope 7 to pull the pouring bucket, thereby obtaining the two clamping rods 83 on the pitch circle position. The lifting speed is approximately equal to the lifting speed of the pouring bucket (the speed at which the winding shaft 61 drives the traction rope 7 to pull the pouring bucket is twice the lifting speed of the pouring bucket, and the speed at which the winding shaft 61 drives the traction rope 7 to pull the pouring bucket is approximately equal to the linear speed of the No. 1 gear 85, and the linear speed of the No. 1 gear 85 is twice the linear speed of the No. 2 gear 86 and the No. 4 gear 88, and the linear speed of the No. 2 gear 86 and the No. 4 gear 88 is equal to the lifting speed of the clamping rod 83, so the lifting speed of the two clamping rods 83 is approximately equal to the lifting speed of the pouring bucket), so the two clamping rods 83 rise approximately synchronously with the pouring bucket; the stability of the pouring bucket is guaranteed during the lifting process of the pouring bucket.

[0060] As a specific implementation of the present invention, a second block 831 is fixedly provided on the top of the clamping rod 83 .

[0061] During operation, a second block 831 is fixedly provided on the top of the clamping rod 83, and the second block 831 can block the clamping rod 83 and the turntable 82 from falling off, thereby preventing the clamping rod 83 from falling off the turntable 82 when descending.

[0062] As a specific implementation of the present invention, a third block 51 is fixedly disposed in the cavity 81 and located on the top of the first block 5 , and the third block 51 connects the c and d parts of the first block 5 .

[0063] During operation, block No. 3 51 is fixedly installed in the cavity 81 and on the top of block No. 1 5. Block No. 3 51 connects parts c and d of block No. 1 5. When the clamping rod 83 is in a vertical state, the clamping rod 83 just contacts with block No. 3 51. On the one hand, this arrangement increases the connection firmness of parts c and d of block No. 1 5; on the other hand, due to the obstruction of block No. 3 51, the clamping rod 83 will not continue to approach when it moves to the vertical state, so that the rack 89 on the clamping rod 83 can stably engage with gear No. 2 86 and gear No. 4 88.

[0064] As a specific implementation of the present invention, a semicircular tray 832 is fixedly connected to the bottom of the clamping rod 83 .

[0065] During operation, a semicircular tray 832 is fixedly connected to the bottom of the clamping rod 83. When the clamping rod 83 is in a vertical state, the two semicircular trays 832 can form a full circle. When the hook 72 lifts the pouring bucket, the tray 832 can support the bottom of the pouring bucket. Therefore, even if the pouring bucket is separated from the hook 72 during lifting, the tray 832 can support the pouring bucket to prevent the pouring bucket from falling, thereby increasing safety. Due to the presence of the brake mechanism, when the No. 1 motor 6 stops driving, the brake mechanism can also prevent the winding shaft 61 from rotating. Since the No. 2 gear 86 and the No. 4 gear 88 are respectively engaged with the rack 89 on the clamping rod 83, the clamping rod 83 can be prevented from moving downward. Therefore, during transportation, even if the pouring bucket is separated from the hook 72, the clamping rod 83 will not move downward under the action of the gravity of the pouring bucket, and then the tray 832 can support the pouring bucket, thereby ensuring safety.

[0066] As a specific embodiment of the present invention, the arc-shaped side wall of the clamping frame 84 close to the hook 72 is fixedly connected with a clamping rod 841, and the clamping rod 841 is formed by slidingly sleeved two hollow short rods of different diameters and a spring is arranged inside.

[0067] During operation, when the clamping frame 84 clamps the side wall of the pouring bucket, the clamping rod 841 contacts the side wall of the pouring bucket. The clamping rod 841 is composed of two hollow short rods of different diameters that are slidably connected and a spring is arranged inside. The spring contraction amount is different according to the diameter of the pouring bucket. On the one hand, this arrangement enables the clamping frame 84 to adapt to pouring buckets of different diameters. On the other hand, the spring has a buffering effect, absorbs vibration, and plays a shock-absorbing role in the lifting and transportation of the pouring bucket.

[0068] As a specific implementation of the present invention, electromagnets 842 are fixedly provided at the ends of the clamping frame 84 that are close to each other.

[0069] During operation, when the clamping frames 84 are combined with each other, the electromagnet 842 is started to make the clamping frames 84 attract each other, reduce the separation of the clamping rods 83, and enhance the stability of the device; when the pouring bucket needs to be lowered, the electromagnet 842 can be turned off to make the electromagnet 842 lose its magnetism, which is conducive to the separation of the clamping rods 83.

[0070] The specific workflow is as follows:

[0071] First, hang the pouring bucket on the hook 72, start the No. 1 motor 6, so that the winding shaft 61 rotates, one end of the traction rope 7 is fixedly connected to the bottom of the c part of the No. 1 block 5, and the other end is fixedly connected to the winding shaft 61. Therefore, the rotation of the winding shaft 61 can wind the traction rope 7 around the winding shaft 61 to achieve the lifting of the pouring bucket. In addition, the hook 72 and the traction rope 7 adopt a movable pulley 71 structure, which has a labor-saving effect; a brake mechanism is provided in the No. 1 block 5 to limit the rotation of the output shaft of the No. 1 motor 6 under the action of the gravity of the pouring bucket after the pouring bucket is lifted, so as to prevent the pouring bucket from falling to the ground with the hook 72 under the action of gravity when the crane stops working; then the pulley cooperates with the slide rail 1 to achieve the pouring The pouring bucket is transported; in this process, a driving motor is fixedly arranged inside the control box 4, and one of the turntables 82 is fixedly connected to the output shaft of the driving motor. The driving motor is a low-speed motor. The driving motor is controlled to rotate, so that one of the turntables 82 rotates. Since the turntable 82 is close to the side wall of the control box 4 and the side close to the turntable 82 is provided with a latching tooth 821, the latching teeth 821 are engaged with each other, and there are two clamping rods 83 and both penetrate the turntable 82 and are slidably connected to the turntable 82, the rotation of the driving motor can drive the two turntables 82 to rotate in the opposite direction, thereby making the clamping rods 83 approach or move away from each other. When the hook 72 lifts the pouring bucket, the driving motor is controlled to make the clamping frame 84 lift the pouring bucket. The side wall of the pouring bucket is clamped, and the clamping frame 84 is composed of a semicircular ring, which can adapt to the arc structure of the side wall of the pouring bucket; after the pouring bucket is clamped, the pouring bucket moves up, and since the clamping rods 83 penetrate the turntable 82 and are slidably connected to the turntable 82, the pouring bucket can drive the clamping rods 83 to rise together, so that the clamping rods 83 cooperate with the clamping frame 84 to clamp the pouring bucket during the lifting and transportation of the pouring bucket. The clamping rod 83 is a rigid structure, and the clamping rod 83 in the turntable 82 limits the relative displacement of the clamping rod 83 and the control box 4 and the No. 1 block 5, so this setting can limit the swing of the pouring bucket during the lifting and transportation process; ensure the stability of the pouring bucket during the lifting and transportation process; in addition, When the turntable 82 drives the clamping rod 83 and the clamping frame 84 to clamp the pouring ladle, the clamping rod 83 is in a vertical state at this time, and the racks 89 on the two clamping rods 83 are respectively meshed with the No. 2 gear 86 and the No. 4 gear 88. When the winding shaft 61 rotates counterclockwise to lift the pouring ladle, the No. 1 gear 85 coaxial with the winding shaft 61 rotates, and the No. 1 gear 85 drives the No. 2 gear 86 to rotate, and the No. 2 gear 86 drives the clamping rod 83 on the left and makes it move upward. Similarly, the rotation of the No. 1 gear 85 also drives the No. 3 gear 87 to rotate, and the No. 3 gear 87 drives the No. 4 gear 88 to rotate, and the No. 4 gear 88 drives the clamping rod 83 on the right to move and make it move upward.
