Description

Technical Field

[0001] The utility model belongs to the technical field of transformer manufacturing, and in particular relates to a silicon steel sheet raw material roll hoisting and feeding mechanism. Background Art

[0002] In the production of silicon steel sheets, the rolled steel sheet raw material rolls need to be cut obliquely to form long sheets of trapezoidal silicon steel sheets. Therefore, the raw material rolls of silicon steel sheets are in a ring structure with a large diameter and a small width. Raw material rolls of this shape are difficult to stand up and fix during transportation, and can only be transported by lying flat.

[0003] However, after the raw material rolls are transported to the workshop, due to their heavy weight, a forklift is required to scoop and move them when they are transferred and loaded in the workshop. However, the forklift's fork is too thick to reach between the raw material roll and the ground to lift it. Therefore, the other end of the raw material roll needs to be supported, and the forklift's fork squeezes the surface of the raw material roll and deforms the outer layer of the raw material roll at a certain angle before reaching under the raw material roll. However, this operation will cause several layers on the surface of the raw material roll to be scrapped, thus wasting raw materials. Utility Model Content

[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a silicon steel sheet raw material roll hoisting and feeding mechanism, which uses a scissor-shaped feeding mechanism to lift one side of the raw material roll with the help of a crane and feed it to avoid damage to the surface of the raw material roll.

[0005] The specific technical solution adopted by the utility model is:

[0006] A silicon steel sheet raw material roll hoisting and feeding mechanism, one end of the feeding mechanism is connected to the crane by means of a lifting rope, and the other end of the feeding mechanism clamps the raw material roll and lifts it by means of the crane, the feeding mechanism includes a first clamping rod and a second clamping rod hinged to each other in a scissors shape, the first clamping rod and the second clamping rod are respectively located at the inner ring and the outer ring of the raw material roll, a fixing ring is provided at the end of the first clamping rod away from the raw material roll, one end of the lifting rope is fixedly connected to the crane, the other end of the lifting rope passes through the fixing ring and is fixedly connected to one end of the second clamping rod close to the crane, after lifting, the second clamping rod forms a closing tendency with the first clamping rod by its own gravity and clamps and fixes the raw material roll, a wedge-shaped block-shaped pad portion is added to the bottom of the first clamping rod, and the tip of the pad portion is embedded between the raw material roll and the ground.

[0007] The foot pad and the first clamping rod body are arranged in an L shape, and the tip of the foot pad is embedded in the gap between the raw material roll and the ground and clamps the raw material roll together with the first clamping rod and the second clamping rod.

[0008] A first rubber gasket is fixed to the contact end of the second clamping rod and the raw material roll, and the second clamping rod contacts the raw material roll by means of the first rubber gasket.

[0009] A basket bolt is also provided between the first clamp rod and the raw material roll. The basket bolt and the foot are respectively located on both sides of the first clamp rod. The two ends of the basket bolt are respectively abutted against the first clamp rod and one end of the inner ring of the raw material roll. The first clamp rod applies force toward the other end of the inner ring of the raw material roll by means of the extension of the basket bolt.

[0010] The basket bolt includes a left-handed bolt, a right-handed bolt and a shell, and both ends of the shell are respectively provided with assembly holes with internal threads. The left-handed bolt and the right-handed bolt respectively pass through the assembly holes at one end of the shell and form a threaded connection with the shell. The surface threads of the left-handed bolt and the right-handed bolt have opposite directions. The left-handed bolt and the right-handed bolt move in opposite directions with the help of the rotation of the shell, and the basket bolt is extended or shortened with the help of the movement of the left-handed bolt and the right-handed bolt.

[0011] The contact end of the left-handed bolt and the raw material roll is provided with a second rubber gasket, and the left-handed bolt abuts against the raw material roll and is fixed with the help of the second rubber gasket.

[0012] The beneficial effects of the utility model are:

When in use, the first clamp rod and the second clamp rod are respectively located at the inner ring and the outer ring of the raw material roll. When the crane is raised, since the end of the lifting rope passes through the fixed ring and is fixedly connected to the end of the second clamp rod, the connection end of the second clamp rod and the lifting rope tends to overlap with the fixed ring, that is, the first clamp rod and the second clamp rod tend to be closed. At the same time, since the first clamp rod is provided with a foot pad, the raw material roll is supported by the foot pad. Under the pressure of the weight of the raw material roll, the first clamp rod and the second clamp rod clamp and fix the raw material roll to form a tight clamp, and then the raw material roll is lifted by the crane and transferred to the expansion shaft to complete the loading, thereby avoiding damage to the surface of the raw material roll.

DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0018] Specific embodiments, such as Figure 1-2 As shown, the utility model provides a silicon steel sheet raw material roll hoisting and feeding mechanism, one end of the feeding mechanism is connected to the hoisting machine 2 by means of a lifting rope 1, and the other end of the feeding mechanism clamps the raw material roll 3 and lifts it by means of the lifting machine 2. The feeding mechanism includes a first clamping rod 4 and a second clamping rod 5 hinged to each other in a scissors shape, the first clamping rod 4 and the second clamping rod 5 are respectively located at the inner ring and the outer ring of the raw material roll 3, and a fixing ring 6 is provided at the end of the first clamping rod 4 away from the raw material roll 3, one end of the lifting rope 1 is fixedly connected to the hoisting machine 2, the other end of the lifting rope 1 passes through the fixing ring 6 and is fixedly connected to one end of the second clamping rod 5 close to the hoisting machine 2, after lifting, the second clamping rod 5 forms a closing tendency with the first clamping rod 4 by its own gravity and clamps and fixes the raw material roll 3, and a wedge-shaped block-shaped pad 7 is added to the bottom of the first clamping rod 4, and the tip of the pad 7 is embedded between the raw material roll 3 and the ground.

[0019] Since the raw material roll 3 is heavy, a forklift is needed to scoop and move it when it is transferred and loaded in the workshop. However, the fork of the forklift is too thick to extend between the raw material roll 3 and the ground to lift it. Therefore, the other end of the raw material roll 3 needs to be supported, and the fork of the forklift squeezes the surface of the raw material roll 3 and deforms the outer layer of the raw material roll 3 at a certain angle before extending under the raw material roll 3. However, this operation will cause several layers on the surface of the raw material roll 3 to be scrapped, thus wasting raw materials.

[0020] Therefore, the utility model uses a scissor-shaped loading mechanism to lift one side of the raw material roll 3 with the help of the crane 2 and load the raw material. When in use, the first clamping rod 4 and the second clamping rod 5 are respectively located at the inner ring and the outer ring of the raw material roll 3. When the crane 2 is raised, since the end of the lifting rope 1 passes through the fixed ring 6 and is fixedly connected to the end of the second clamping rod 5, the connection end of the second clamping rod 5 and the lifting rope 1 tends to overlap with the fixed ring 6, that is, the first clamping rod 4 and the second clamping rod 5 tend to be closed. At the same time, since the first clamping rod 4 is provided with a foot portion 7, the raw material roll 3 is supported by the foot portion 7. Under the pressure of the weight of the raw material roll 3, the first clamping rod 4 and the second clamping rod 5 clamp and fix the raw material roll 3 to form a tight clamping, and then the raw material roll 3 is lifted by the crane 2 and transferred to the expansion shaft to complete the loading, thereby avoiding damage to the surface of the raw material roll 3.

[0021] The foot portion 7 and the main body of the first clamping rod 4 are arranged in an L shape, and the tip of the foot portion 7 is embedded in the gap between the raw material roll 3 and the ground and clamps the raw material roll 3 together with the first clamping rod 4 and the second clamping rod 5. The wedge-shaped structure of the foot portion 7 makes it easier for the foot portion 7 to extend into the gap between the raw material roll 3 and the ground.

[0022] A first rubber gasket 8 is fixed to the contact end of the second clamping rod 5 and the raw material roll 3. The second clamping rod 5 contacts the raw material roll 3 with the help of the first rubber gasket 8. By setting the first rubber gasket 8, the friction between the second clamping rod 5 and the raw material roll 3 can be increased to increase the tight clamping of the raw material roll 3 and prevent the raw material roll 3 from falling off during the loading process.

[0023] A basket bolt is also provided between the first clamping rod 4 and the raw material roll 3, and the basket bolt and the pad 7 are respectively located on both sides of the first clamping rod 4, and the two ends of the basket bolt are respectively abutted against the first clamping rod 4 and one end of the inner ring of the raw material roll 3, and the first clamping rod 4 applies force toward the other end of the inner ring of the raw material roll 3 by means of the extension of the basket bolt. In order to prevent the first clamping rod 4 from shaking and causing the feeding mechanism to be unable to tightly clamp the raw material roll 3, the utility model is also provided with a basket bolt. Before feeding, the basket bolt is fastened to the inner ring of the raw material roll 3, and then the basket bolt is rotated forward to extend the basket bolt until the two ends of the basket bolt are respectively abutted against the inner ring of the raw material roll 3 and the first clamping rod 4. At this time, the first clamping rod 4 is fixed under the support of the basket bolt, thereby tightly clamping the raw material roll 3 with the second clamping rod 5. When the feeding is completed, the basket bolt is reversed to shorten the basket bolt and disassemble it.

[0024] The basket bolt includes a left-handed bolt 9, a right-handed bolt 10 and a shell 11. Both ends of the shell 11 are respectively provided with assembly holes with internal threads. The left-handed bolt 9 and the right-handed bolt 10 respectively pass through the assembly holes at one end of the shell 11 and form a threaded connection with the shell 11. The surface threads of the left-handed bolt 9 and the right-handed bolt 10 are in opposite directions. The left-handed bolt 9 and the right-handed bolt 10 move in opposite directions with the help of the rotation of the shell 11, and the basket bolt is extended or shortened with the help of the movement of the left-handed bolt 9 and the right-handed bolt 10.

[0025] The contact end of the left-handed bolt 9 and the raw material roll 3 is provided with a second rubber gasket 12, and the left-handed bolt 9 is abutted and fixed with the raw material roll 3 by means of the second rubber gasket 12, and the contact end of the right-handed bolt 10 and the first clamping rod 4 is provided with a hook 13, and the first clamping rod 4 is provided with a hanging hole 14 for the hook 13 to hook, and the right-handed bolt 10 is hooked and fixed with the first clamping rod 4 by means of the hook 13, and the hanging hole 14 and the pad foot part 7 are respectively located on both sides of the first clamping rod 4. It is difficult to push the pad foot part 7 to the bottom of the raw material roll 3 by manpower. Therefore, the pad foot part 7 is pushed to the bottom of the raw material roll 3 by the force generated by the extension of the basket bolt, and the shell 11 of the basket bolt is rotated, which is convenient for the staff to apply force. The second rubber gasket 12 has good deformation ability, so the second rubber gasket 12 can be adapted to the arc surface of the inner ring of the raw material roll 3. At the same time, the rubber material has a large friction coefficient. The second rubber gasket 12 can hinder the synchronous rotation of the left-handed bolt 9 and the shell 11 to ensure the extension and shortening of the basket bolt.
