Description

Technical Field

[0001] The invention relates to the technical field of wear-resistant material lifting equipment, in particular to a lifting device for wear-resistant material production. Background Art

[0002] Wear-resistant materials refer to special materials with special electrical, magnetic, optical, acoustic, thermal, mechanical, chemical and biological functions. They are widely used in information technology and energy technology. In the production and processing of wear-resistant materials, the raw materials of wear-resistant materials need to be lifted and transported to the corresponding position for processing, so a wear-resistant material lifting device is needed.

[0003] In order to prevent the bucket from shaking during the lifting process and causing the wear-resistant material to fall, a mechanical clamp is generally configured on the lifting seat of the existing elevator to clamp the bucket and enhance the stability of the bucket during the lifting process.

[0004] However, the existing mechanical clamp is fixed in the assembly position on the lifting seat. When clamping barrels of different heights, the clamping position of the clamp will deviate from the middle of the barrel, so that the center of gravity of the barrel is shifted, reducing the stability of the barrel.

[0005] In addition, the clamps of existing mechanical clamps are generally configured in an arc shape that matches the shape of the barrel. The arc clamp has a single structure and its shape is designed according to the specific barrel size. When encountering barrels with different outer diameters, the arc clamp with a fixed size structure is difficult to achieve effective clamping. Summary of the invention

[0006] In order to solve the above technical problems, a lifting device for wear-resistant material production is provided, which solves the problem of poor applicability of mechanical clamps in the prior art.

[0007] To achieve the above purpose, the technical solution adopted by the present invention is: a lifting device for wear-resistant material production, comprising an L-shaped support frame, a bearing platform lifted and lowered inside the support frame, and a barrel placed on the bearing platform, a lifting power mechanism is arranged between the bearing platform and the vertical section of the support frame, and also comprises a deformable ring-type positioning mechanism for stabilizing barrels of different shapes and a flexible adjustment mechanism for enhancing the adaptability of the deformable ring-type positioning mechanism;

[0008] The deformable ring-type positioning mechanism comprises an annular sleeve seat in a circular ring shape, a mounting plate vertically fixed to the middle of one side wall of the bearing platform, and a centrifugal pump mounted on the mounting plate, the inner ring surface of the annular sleeve seat is open, and an airbag sheet is fixed in the open hole, and an air delivery pipe is fixedly connected between the air delivery end of the centrifugal pump and the annular sleeve seat;

[0009] The flexible adjustment mechanism includes a power cylinder vertically fixed to the top surface of the mounting plate by a bracket, a movable sleeve slidingly provided on the cylinder wall of the power cylinder and fixedly connected to the annular sleeve seat, a limiting groove is provided on the side of the power cylinder away from the barrel, a limiting block fixedly connected to the end surface of the movable sleeve is slidingly provided in the limiting groove, and a power part cooperating with the limiting block is provided on the inner side of the power cylinder.

[0010] Preferably, a gear-shaped reinforcement ring is fixedly mounted on the outer wall of the barrel, and a plurality of positioning rubber strips are attached to the inner wall of the airbag sheet, and the two ends of the positioning rubber strips are respectively fixed to the two end surfaces of the annular sleeve.

[0011] Preferably, the limiting groove is in an inverted L-shape and is connected to the interior of the power cylinder.

[0012] Preferably, the power unit includes a control screw rod vertically arranged inside the power cylinder and an internal threaded sleeve threadedly sleeved on the shaft of the control screw rod, and the limit block penetrates into the power cylinder and is fixedly connected to the internal threaded sleeve.

[0013] Preferably, a supply seat is provided on the side of the power cylinder and is fixedly connected vertically to the top surface of the mounting plate. A driving rod is rotatably provided on the inner side of the supply seat. One end of the driving rod is tightly sleeved with the supply seat. The bottom end of the control screw rotates through the power cylinder and is connected to the other end of the driving rod through a bevel gear transmission.

[0014] Preferably, a cover plate is provided above the annular sleeve, and a T-shaped guide rod fixedly connected to the top surface of the annular sleeve is symmetrically penetrated through the top surface of the cover plate.

[0015] Preferably, the rod body of the T-shaped guide rod is sleeved with a compression spring, and the two ends of the compression spring are respectively fixedly connected to the top surface of the cover plate and the transverse section of the compression spring.

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) By setting up the deformable ring-shaped positioning mechanism, the centrifugal pump is started to continuously pump air into the annular sleeve, gradually increasing the pressure on the airbag sheet, so that the airbag sheet continuously expands toward the inside of the annular sleeve, reducing the inner diameter of the annular sleeve until the airbag sheet contacts the surface of the barrel, thereby forming a ring-shaped positioning for the barrel. In this way, while basically achieving the effect of positioning the barrel, based on the characteristic that the inner diameter of the annular sleeve can be reduced, the device can position and stabilize barrels of different outer diameters, and utilizes the flexible characteristics of the airbag so that it will not cause hard damage to the surface of the barrel when it contacts the barrel, thereby reducing damage to the barrel.

[0018] (2) By setting the gear-type reinforcement ring and the positioning rubber strip, the gear-type reinforcement ring can be used to strengthen the wall thickness of the barrel to a certain extent, thereby improving the barrel's resistance to deformation. The tooth groove on the gear-type reinforcement ring can also be used. When the airbag sheet is inflated by air and connected to the barrel, the positioning rubber strip can be deformed synchronously with the expansion of the airbag sheet until it is stuck in the tooth groove of the gear-type reinforcement ring. In this way, the barrel can be further positioned to prevent the barrel from deflecting during the lifting process, thereby improving the stability effect.

[0019] (3) By setting up a flexible adjustment mechanism, the power unit can be used to flexibly raise and lower the annular sleeve, thereby facilitating the rapid adjustment of the position of the deformable ring-type positioning mechanism according to the height of the barrel to be lifted, so that the deformable ring-type positioning mechanism can always be positioned in the middle of the barrel, so as to avoid reducing the positioning effect of the barrel due to position deviation.

[0020] (4) By setting the limit groove in an inverted L shape, the limit block can be limited to drive the movable sleeve to rotate horizontally first and then move linearly downward along the power cylinder. During this period, when the limit block rotates along the horizontal section of the limit groove, the movable sleeve synchronously deflects the annular sleeve seat as a whole to the top of the support platform, so that it corresponds to the upper and lower parts of the barrel. Subsequently, when the limit block further moves downward along the vertical section of the limit groove, the movable sleeve carries the annular sleeve seat as a whole to the outside of the barrel. In this way, the movable sleeve can be lifted and deflected by utilizing the characteristics of the movable sleeve that can be lifted and deflected, so as to facilitate the deformation type ring type positioning mechanism to be deviated from the top of the support platform, reduce the movement resistance of the deformation type ring type positioning mechanism to the pulling and pushing of the barrel, and improve the flexibility of the device.

[0021] (5) By setting the covering plate, when the power unit is used to move the movable sleeve to carry the annular sleeve seat downward and set on the outside of the barrel, the covering plate contacts the opening of the barrel and is hindered from remaining on the opening of the barrel during the further downward process of the annular sleeve seat. In this way, the open end of the barrel is effectively covered without affecting the mobility of the annular sleeve seat, the inner side of the barrel is sealed, and the anti-spill effect of the material inside the barrel is enhanced.

[0029] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] Reference Figure 1-5 As shown, a lifting device for wear-resistant material production includes an L-shaped support frame 1, a bearing platform 2 that is lifted and lowered inside the support frame 1, and a material barrel 3 placed on the bearing platform 2;

[0031] A lifting power mechanism is provided between the bearing platform 2 and the vertical section of the support frame 1;

[0032] The lifting power mechanism includes a lifting seat 4 fixed to one side of the supporting platform 2, a screw rod 6 threadedly penetrating the inner wall of one end of the lifting seat 4, and a limit support rod 7 slidingly penetrating the inner wall of the other end of the lifting seat 4, a driving motor 5 is installed at the bottom end of the screw rod 6, the bottom end of the limit support rod 7 is fixedly connected to the inner wall of the bottom end of the support frame 1, and the driving motor 5 is fixed to the bottom of the support frame 1 by bolts;

[0033] Through the setting of the lifting mechanism and the supporting platform 2, after the material barrel 3 is pushed onto the supporting platform 2, the driving motor 5 is turned on to cause the screw rod 6 to rotate, and the lifting seat 4 can carry the supporting platform 2 and the material barrel 3 as a whole to move upward under the threaded structure, thereby achieving the lifting effect of the material barrel 3.

[0034] In order to prevent the bucket 3 from shaking during the lifting process, a mechanical clamp is generally configured on the supporting platform 2 of the existing hoist, and the mechanical clamp is used to clamp the bucket 3 to strengthen the stability of the bucket 3 during the lifting process. However, the clamping plate of the existing mechanical clamp is generally configured in an arc shape that matches the shape of the bucket 3. The arc clamping plate has a single structure and its shape is designed according to the size of a specific bucket 3. When encountering buckets 3 with different outer diameters, the arc clamping plate with a fixed size structure is difficult to achieve effective clamping;

[0035] Moreover, the existing barrel 3 is mostly made of stainless steel or iron sheet, and its wall thickness is relatively thin. Once the manual operation is improper, the arc clamping plate will excessively contact with the outer wall of the barrel 3, which will seriously cause the barrel 3 to be deformed or damaged.

[0036] For this purpose, refer to Figure 1-4 As shown, it is worth noting that it also includes a deformable ring-type positioning mechanism for stabilizing barrels of different shapes;

[0037] The deformable ring-type positioning mechanism includes a circular annular sleeve 9, a mounting plate 8 vertically fixed to the middle of one side wall of the bearing platform 2, and a centrifugal pump 11 mounted on the mounting plate 8. The inner ring surface of the annular sleeve 9 is open, and an airbag sheet 10 is fixed in the open opening. An air delivery pipe 12 is fixedly connected between the air delivery end of the centrifugal pump 11 and the annular sleeve 9. The outer wall of the annular sleeve 9 is also provided with an air release valve (not shown in the figure);

[0038] After the barrel 3 is pushed onto the carrier 2, the annular sleeve 9 is pre-mounted on the outside of the barrel 3. If there is a gap between the annular sleeve 9 and the barrel 3 due to size deviation;

[0039] By setting up the deformable ring-shaped positioning mechanism, the centrifugal pump 11 is started to continuously pump air into the annular sleeve 9, gradually increasing the pressure on the airbag sheet 10, so that the airbag sheet 10 continuously expands toward the inside of the annular sleeve 9, reducing the inner diameter of the annular sleeve 9 until the airbag sheet 10 contacts the surface of the barrel 3, thereby forming a ring-shaped positioning for the barrel 3. In this way, while basically achieving the effect of positioning the barrel 3, based on the characteristic that the inner diameter of the annular sleeve 9 can be reduced, the device can position and stabilize barrels 3 with different outer diameters, and utilizes the flexible characteristics of the airbag so that it will not cause hard damage to the surface of the barrel 3 when contacting the barrel 3, thereby reducing damage to the barrel 3.

[0040] Further, refer to Figure 2 and Figure 4 As shown, it is worth noting that the outer wall of the barrel 3 is fixedly sleeved with a gear-shaped reinforcement ring 25, and the inner wall of the airbag sheet 10 is attached with a plurality of positioning rubber strips 24, and the two ends of the positioning rubber strips 24 are respectively fixed to the two end surfaces of the annular sleeve 9;

[0041] By setting the gear-type reinforcement ring 25 and the positioning rubber strip 24, the gear-type reinforcement ring 25 can be used to strengthen the wall thickness of the barrel 3 to a certain extent, thereby improving the resistance of the barrel 3 to deformation. The tooth grooves on the gear-type reinforcement ring 25 can also be used. When the airbag sheet 10 is inflated by air and connected to the barrel 3, the positioning rubber strip 24 can be deformed synchronously with the expansion of the airbag sheet 10 until it is stuck in the tooth grooves of the gear-type reinforcement ring 25. In this way, the barrel 3 can be further positioned to prevent the barrel 3 with a hub from deflecting during the lifting process, thereby improving the stability effect.

[0042] In addition, refer to Figure 2 , Figure 3 as well as Figure 5 As shown, it is worth noting that it also includes a flexible adjustment mechanism to enhance the adaptability of the deformable ring-type positioning mechanism;

[0043] The flexible adjustment mechanism includes a power cylinder 13 vertically fixed on the top surface of the mounting plate 8 by a bracket, a movable sleeve 14 fixedly connected to the annular sleeve seat 9 is slidably provided on the cylinder wall of the power cylinder 13, a limiting groove 16 is provided on the side of the power cylinder 13 away from the barrel 3, a limiting block 17 fixedly connected to the end surface of the movable sleeve 14 is slidably provided in the limiting groove 16, and a power part cooperating with the limiting block 17 is provided on the inner side of the power cylinder 13;

[0044] By setting up a flexible adjustment mechanism, the power unit can be used to flexibly lift and lower the annular sleeve 9, thereby facilitating the rapid adjustment of the position of the deformable ring-type positioning mechanism according to the height of the barrel 3 to be lifted, so that the deformable ring-type positioning mechanism can always be positioned in the middle of the barrel 3 to avoid reducing the positioning effect of the barrel 3 due to position deviation.

[0045] In addition, refer to Figure 2 and Figure 3 As shown, it is worth noting that the limiting groove 16 is in an inverted L shape and is connected to the inside of the power cylinder 13;

[0046] By setting the limit groove 16 in an inverted L shape, the limit block 17 can be limited to drive the movable sleeve 14 to first rotate horizontally and then move linearly downward along the power cylinder 13. During this period, when the limit block 17 rotates along the horizontal section of the limit groove 16, the movable sleeve 14 synchronously deflects the annular sleeve seat 9 as a whole to the top of the support platform 2, so that it corresponds to the barrel 3 up and down. Subsequently, when the limit block 17 further moves downward along the vertical section of the limit groove 16, the movable sleeve 14 carries the annular sleeve seat 9 as a whole to the outside of the barrel 3. In this way, the movable sleeve 14 can be lifted and deflected by utilizing the characteristics of the movable sleeve 14 that can be lifted and deflected, so as to facilitate the deformation type ring type positioning mechanism to deviate from the top of the support platform 2, thereby reducing the movement resistance of the deformation type ring type positioning mechanism to the pulling and pushing of the barrel 3.

[0047] Further, refer to Figure 5 As shown, it is worth noting that the power unit includes a control screw 18 vertically arranged inside the power cylinder 13 and an internal thread sleeve 15 threadedly sleeved on the shaft of the control screw 18, and a limit block 17 penetrates into the power cylinder 13 and is fixedly connected to the internal thread sleeve 15;

[0048] A rotating seat 19 is arranged on the side of the power cylinder 13 and is fixedly connected to the top surface of the mounting plate 8 vertically. A driving rod is rotated inside the rotating seat 19. One end of the driving rod is tightly sleeved with the rotating seat 20. The bottom end of the control screw 18 rotates and passes through the power cylinder 13 and is connected to the other end of the driving rod through a bevel gear transmission.

[0049] The supply swivel seat 20 is rotated to make the driving rod drive the control screw 18 through the bevel gear. If the limit block 17 is initially located in the transverse section of the limit groove 16, the internal thread sleeve 15 is in an unrestricted role, and it can carry the limit block 17 to deflect inside the transverse section of the limit groove 16 along with the rotation of the control screw 18;

[0050] Until the limit block 17 deflects to abut the inner side wall of the horizontal section of the limit groove 16, the limit block 17 can then limit the internal threaded sleeve 15 during further rotation of the control screw 18, so that the internal threaded sleeve 15 slides down along the vertical section of the limit groove 16 under the threaded structure, thereby achieving the effect of deflection and lifting of the movable sleeve 14.

[0051] Further, refer to Figure 4 As shown, it is worth noting that a cover plate 21 is provided above the annular sleeve 9, and a T-shaped guide rod 22 fixedly connected to the top surface of the annular sleeve 9 is symmetrically penetrated through the top surface of the cover plate 21;

[0052] By setting the covering plate 21, when the movable sleeve 14 is driven by the power unit to carry the annular sleeve seat 9 downward and sleeved on the outside of the barrel 3, the covering plate 21 contacts the opening of the barrel 3 and is hindered from remaining on the opening of the barrel 3 during the further downward process of the annular sleeve seat 9. In this way, the open end of the barrel 3 is effectively covered without affecting the mobility of the annular sleeve seat 9, the inner side of the barrel 3 is sealed, and the anti-spillage effect of the material inside the barrel 3 is enhanced.

[0053] Further, refer to Figure 4 As shown, it is worth noting that the rod body of the T-shaped guide rod 22 is sleeved with a compression spring 23, and the two ends of the compression spring 23 are respectively fixedly connected to the top surface of the cover plate 21 and the transverse section of the compression spring 23;

[0054] Through the setting of the compression spring 23, when the cover plate 21 contacts the opening of the barrel 3, the annular sleeve 9 can synchronously carry the T-shaped guide rod 22 downward and compress the compression spring 23 to deform during the further downward process. In this way, the elastic force of the compression spring 23 is utilized to apply pressure to the cover plate 21, thereby enhancing the covering effect of the cover plate 21 on the opening of the barrel 3 and improving the sealing inside the barrel 3.
