Description

Technical Field

[0001] This application relates to the field of aluminum-clad steel wire processing technology, specifically to an aluminum-clad steel wire screening device. Background Technology

[0002] Aluminum-clad steel wire, with its unique electrical and mechanical properties, is widely used in some overhead power lines. It is a bimetallic wire composed of steel and aluminum, possessing both the high conductivity of aluminum and the strength of steel. In the early 21st century, it was extensively designed and used in large-span engineering projects. However, as a primary load-bearing component, aluminum-clad steel wire, unlike aluminum or aluminum alloy wire, cannot have any form of splicing. This necessitates strict screening of the aluminum-clad steel wire used in strand production, with the diameter selection being one aspect of this screening process.

[0003] Currently, existing methods for screening aluminum-clad steel wire diameters can generally only screen aluminum-clad steel wires of a specific diameter. When screening aluminum-clad steel wires of different diameters, different screening devices need to be used, which has certain limitations and poor applicability. Utility Model Content

[0004] The purpose of this application is to provide an aluminum-clad steel wire screening device that solves the problems mentioned in the background art.

[0005] This application provides an aluminum-clad steel wire screening device, including a base plate, a vertical plate connected to the upper end of the base plate, a through hole on the side wall of the vertical plate, a rotating shaft rotatably connected to one side wall of the vertical plate, and a screening disc connected to the other end of the rotating shaft. A plurality of screening holes of different diameters are evenly spaced in a ring on the side wall of the screening disc, with the through holes corresponding to the positions of the screening holes. A lead screw is rotatably connected to one side wall of the vertical plate, a movable block is threaded onto the wall of the lead screw, and a rack is connected to one end of the movable block. A gear is fixedly sleeved on the shaft wall of the rotating shaft, and the rack meshes with the gear.

[0006] By adopting the above technical solution, during screening, the aluminum-clad copper wires to be screened are sequentially passed through the through holes and the corresponding screening holes. Wires passing through the corresponding screening holes are considered qualified, and vice versa. When screening aluminum-clad steel wires of different diameters, the lead screw is rotated. The lead screw applies force to the movable block through the threaded action. The movable block, under this force, drives the rack to move vertically. The rack's movement applies force to the gear, which in turn drives the rotating shaft to rotate. The rotation of the rotating shaft drives the screening disc to rotate. When the corresponding screening hole on the screening disc rotates to the through hole position, the lead screw is stopped. The aluminum-clad steel wires are then screened through this operation. This structure allows for changing the screening holes, facilitating the screening of aluminum-clad steel wires of different diameters, thereby improving the applicability of the device.

[0007] Optionally, a number of reduction motors are installed in a ring at equal intervals on one side wall of the screening disc, and the reduction motors correspond to the positions of the corresponding screening holes. The output end of the reduction motor is connected to a limit block through a coupling. A limit plate is connected to one side wall of the vertical plate, and the limit plate abuts against the corresponding limit block.

[0008] By adopting the above technical solution, when changing the screening hole, the corresponding reduction motor is started, which drives the limit block to rotate. When the limit block rotates to the designated position, the reduction motor is turned off. When the corresponding limit block moves the position of the limit plate, the limit plate will limit the limit block to prevent the screening disc from continuing to rotate. Thus, the position of the screening hole can be positioned, improving the practicality of the device.

[0009] Optionally, a sliding groove is provided on one side wall of the vertical plate, and a slider is slidably connected in the sliding groove, with one end of the slider connected to the movable block.

[0010] By adopting the above technical solution, the movable block is limited to prevent it from rotating.

[0011] Optionally, a slide rod is fixedly connected to the inner wall of the chute, the slide rod passes through the slider, and the slider is slidably connected to the slide rod.

[0012] By adopting the above technical solution, the slider is prevented from detaching from the groove.

[0013] Optionally, one end of the slider is provided with a rolling groove, and a rolling ball is provided in the rolling groove. The rolling ball passes through the opening of the rolling groove and is connected to the bottom of the groove.

[0014] By adopting the above technical solution, the friction between the slider and the groove is reduced.

[0015] Optionally, a rotating block is connected to the upper end of the lead screw.

[0016] By adopting the above technical solution, it is convenient for staff to rotate the lead screw.

[0017] Optionally, a support frame is connected to one side wall of the vertical plate, and the rotating shaft is rotatably connected to the support frame.

[0018] The rotating shaft is supported by adopting the above technical solution.

[0019] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0020] (1) The technical solution of this application allows for the replacement of screening holes by setting up a base plate, vertical plate, through hole, rotating shaft, screening disc, screening hole, lead screw, movable block, rack and gear and other structures, which facilitates the screening of aluminum-clad steel wires of different diameters, thereby improving the applicability of the device.

[0021] (2) The technical solution of this application sets up a structure such as a speed reduction motor, a limit block and a limit plate. When the corresponding speed reduction motor is started, the speed reduction motor will drive the limit block to rotate. When the limit block rotates to the specified position, the speed reduction motor is turned off. When the corresponding limit block moves the position of the limit plate, the limit plate will limit the limit block to prevent the screening disc from continuing to rotate. Thus, the position of the screening hole can be positioned, improving the practicality of the device. Attached Figure Description

[0029] In the technical solution of this application, during screening, the aluminum-clad copper wire to be screened is passed sequentially through the through hole 3 and the corresponding screening hole 6. If it passes through the corresponding screening hole 6, it is qualified, and vice versa. When it is necessary to screen aluminum-clad steel wires of different diameters, the screw 7 is rotated. The screw 7 will apply a force to the movable block 8 through the thread action. The movable block 8 will drive the rack 9 to move vertically. The movement of the rack 9 will apply a force to the gear 10. The gear 10 will drive the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 will drive the screening disk 5 to rotate. When the corresponding screening hole 6 on the screening disk 5 rotates to the position of the through hole 3, the screw 7 is stopped. At this time, the aluminum-clad steel wire is screened through the above operation. The screening hole 6 can be replaced through the above structure, which is convenient for screening aluminum-clad steel wires of different diameters, thereby improving the applicability of the device.

[0030] In the technical solution of this application, a plurality of reduction motors 11 are installed in a ring at equal intervals on one side wall of the screening disc 5, and the positions of the reduction motors 11 and the corresponding screening holes 6 are corresponding. The output end of the reduction motors 11 is connected to the limit block 12 through a coupling. The limit plate 13 is connected to the side wall of one side of the vertical plate 2. The limit plate 13 abuts against the corresponding limit block 12. When the screening hole 6 is changed, the corresponding reduction motor 11 is started, and the reduction motor 11 will drive the limit block 12 to rotate. When the limit block 12 rotates to the designated position, the reduction motor 11 is turned off. When the corresponding limit block 12 moves the position of the limit plate 13, the limit plate 13 will limit the limit block 12 to prevent the screening disc 5 from continuing to rotate. Thus, the position of the screening hole 6 can be positioned, improving the practicality of the device.

[0033] In the technical solution of this application, a rolling groove is provided at one end of the slider 14, and a rolling ball 16 is provided in the rolling groove. The ball 16 passes through the opening of the rolling groove and is rolled and connected to the bottom of the groove, thereby reducing the friction between the slider 14 and the groove.

The lead screw 7 will apply a force to the movable block 8 through the thread action. The movable block 8 will drive the rack 9 to move vertically. The movement of the rack 9 will apply a force to the gear 10. The gear 10 will drive the rotating shaft 4 to rotate. The rotation of the rotating shaft 4 will drive the screening disk 5 to rotate. When the corresponding screening hole 6 on the screening disk 5 rotates to the position of the through hole 3, the lead screw 7 is stopped. At this time, the aluminum-clad steel wires are screened through the above operation.
