Description

Technical Field

[0001] The utility model relates to the technical field of anti-deformation filling, in particular to an anti-deformation filling device for pressing a conical head. Background Art

[0002] Conical head is a type of head, which is shaped like a part of a cone. It is usually used at the end of pressure vessels, storage tanks, pipelines and other equipment to seal and connect.

[0003] For example, in a conical head with the authorization announcement number "CN209041542U", the sealing shell contacts the convex block, and a rubber pad is also arranged in the sealing shell, which ensures the sealing of the first connecting device and the second connecting device. However, during transportation, the conical head will be subjected to external forces such as bumps and collisions, thereby deforming. At the same time, the conical structure of the head causes uneven force distribution, and the force distribution will change with the distance from the vertex. The part close to the vertex is relatively concentrated due to the steep slope of the cone, while the part close to the bottom has a gentle slope and the force is relatively dispersed. The shape of the conical head causes it to deform when subjected to force. Utility Model Content

[0008] Preferably, a rectangular block is fixedly connected to the middle of the upper end of the base, and the upper end of the rectangular block is rotatably connected to a turntable through a ball.

[0009] Preferably, the conical head filling structure includes a second motor, the outer wall of the second motor is fixedly connected to a second housing, the output shaft of the second motor is fixedly connected to a straight rod, both ends of the rotating shaft of the straight rod are rotatably connected to the second housing through bearings, a grip is provided below the straight rod, the end of the grip is fixedly connected to a threaded rod, both ends of the threaded rod are rotatably connected to the straight rod through bearings, the threaded rod is threadedly connected to a threaded block, both ends of the threaded block are slidably connected to a second slide bar, both ends of the second slide bar are fixedly connected to the straight rod, the end of the threaded block is fixedly connected to a vertical block, the outer wall of the vertical block is slidably connected to the second housing, and the lower end of the vertical block is fixedly connected to a box body.

[0010] Preferably, the turntable is threadedly connected to the conical head through a screw, and a top cover is installed at the upper end of the conical head.

[0011] Preferably, a third motor is fixedly connected to the inner wall of the rectangular block, the output shaft of the third motor is rotatably connected to the rectangular block through a bearing, and the output shaft of the third motor is fixedly connected to a turntable.

[0012] A deformation prevention filling device for pressing a conical head proposed by the present utility model has the beneficial effects that: through the cooperation of the conical head filling structure and the second housing, the output shaft of the second motor rotates to drive the straight rod to rotate around the position where the second motor contacts the straight rod, and the rotation of the straight rod drives the box body to rotate, thereby performing a circular sand filling operation on the conical head.

[0013] Through the cooperation of the conical head limiting structure and the first housing, the output shaft of the first motor rotates to drive the cam to rotate. At this time, the spring is compressed by the vertical plate, so the spring always has a rebounding force to push against the vertical plate and keep it in close contact with the cam. As the cam rotates and through the movement of the spring, the vertical plate drives the cross bar to move towards the conical head. The movement of the cross bar drives the round roller to move through the rectangular frame. When the conical head rotates, the two relatively moving rollers can provide stable support and limiting effects, reducing the shaking and offset of the head during rotation, making the rotation of the head more stable, and thus making the sand inside the conical head more even.

[0031] Working principle:

[0032] Installation of the conical head:

[0033] Place the conical head 11 to be processed above the turntable 12 and fix the conical head 11 to the turntable 12 through bolts (as Figure 2 ), and through this setting, conical heads 11 of different sizes can be processed. A plurality of threaded holes are provided inside the turntable 12, and the threaded holes correspond to conical heads 11 of different sizes.

[0034] Anti-deformation operation for the conical head:

[0035] Start the electric telescopic rod 9. The output shaft of the electric telescopic rod 9 moves to drive the second housing 5 to move downward. The movement of the second housing 5 drives the movement of the box body 7. Move the box body 7 to a suitable position, turn off the electric telescopic rod 9, remove the top cover 13 on the conical head 11, open the solenoid valve of the box body 7. The inside of the box body 7 is filled with sand and a solenoid valve is installed at its lower end. The sand slides from the box body 7 into the conical head 11. Through the falling sand filling, internal support can be provided for the conical head 11 to enhance its structural stability. Connect the external power supply of the second motor 601 and start the second motor 601. The output shaft of the second motor 601 rotates to drive the straight bar 602 to rotate around the position where the second motor 601 and the straight bar 602 are in contact (as Figure 5 ), the rotation of the straight bar 602 drives the rotation of the box body, thereby performing a circular falling sand filling operation on the conical head 11. Compared with the traditional falling sand method, the circular filling method can make the sand more evenly distributed inside the conical head 11, avoiding the accumulation or void phenomenon in the traditional falling sand method, thereby improving the filling quality. When processing conical heads of different sizes, a sliding door is provided at the front end of the second housing 5, which is convenient for the operator to turn the handle 603 and open the sliding door. The operator turns the handle 603 to drive the threaded rod 604 to rotate (as Figure 5 ), the rotation of the threaded rod 604 drives the threaded block 605 to move (as Figure 6), the movement of the threaded block 605 drives the movement of the vertical block 607, and the movement of the vertical block 607 drives the movement of the box body 7. The closer the vertical block 607 is to the left and right ends of the inner wall of the second housing 5, the larger the circle formed when the vertical block 607 rotates. The size of the circle formed when the vertical block 607 rotates corresponds to different sizes of the conical head 11, so as to achieve the purpose of filling the conical head 11 with falling sand of different sizes. After closing the sliding door and completing the filling of the conical head 11, close the solenoid valve and turn off the second motor 601;

[0036] The operator selects a round roller 308 corresponding to the size of the conical head 11, and fixes the rectangular frame 307 on the cross bar 306 through bolts 14 (such as Figure 2 ), connect the external power supply of the first motor 301, start the first motor 301, and the output shaft of the first motor 301 rotates to drive the cam 302 to rotate (such as Figure 4 ). At this time, the spring 305 is compressed by the vertical plate 303, so the spring 305 always has a resilient force to push against the vertical plate 303 and keep it in close contact with the cam 302. As the cam 302 rotates and through the movement of the spring 305, the vertical plate 303 drives the cross bar 306 to move towards the conical head 11. The movement of the cross bar 306 drives the round roller 308 to move through the rectangular frame 307 until the outer wall of the round roller 308 is in close contact with the conical head 11. Turn off the first motor 301. The first motor 301 is a servo motor, and the servo motor has a self-locking characteristic, so that the round roller 308 will not displace;

[0037] Place the top cover 13 on the upper end of the conical head 11. A rubber pad is installed at the contact position between the top cover 13 and the conical head 11 to increase friction and make the covering of the top cover 13 tighter. The covering of the top cover 13 prevents the sand inside the conical head 11 from splashing when the conical head 11 rotates. Connect the external power supply of the third motor 10, start the third motor 10, and the output shaft of the third motor 10 rotates to drive the turntable 12 to rotate. The rotation of the turntable 12 drives the conical head 11 to rotate. At this time, the round roller 308 plays a limiting role on the conical head 11, which can effectively limit the shaking and offset of the conical head 11 during rotation and keep it in a stable rotation state. As the conical head 11 rotates, when the conical head 11 rotates, the sand inside will be affected by the centrifugal force, and the centrifugal force will cause the sand to spread outwards, thereby reducing the accumulation of sand in a local area and making the sand distribution more uniform. Turn off the third motor 10 to complete the anti-deformation filling operation of the conical head 11.

[0038] Removal of the conical head:

[0039] Start the electric telescopic rod 9. The movement of the output end of the electric telescopic rod 9 drives the box body 11 to move upward, moving the box body 11 back to its original position for convenient use next time. Turn off the electric telescopic rod 9, remove the bolts of the fixed conical head 11 and the turntable 12, start the first motor 301, and the first motor 301 moves the round roller 308 in the direction opposite to the above-mentioned movement direction. The first motor 301 makes the round roller 308 move away from the conical head 11 through the above-mentioned connection method, and take out the conical head 11, that is, complete the processing process of the anti-deformation filling device for conical head pressing.
