Description

Technical Field

[0001] The utility model relates to a tooling for transformer production, in particular to a miniaturized screw rod lifting platform for transformer core stacking. Background Art

[0002] The core is the core component for changing magnetic flux in a transformer, and its magnetic conductivity directly affects the efficiency of the transformer. By stacking silicon steel sheets, a more efficient magnetic circuit can be formed, thereby improving the magnetic conductivity of the transformer. During the manufacturing process of the transformer core, the cut silicon steel sheets need to be stacked on a rack, and then the rack is hoisted to the core stacking work area for stacking. However, due to the large size of the large-capacity core stacking, when workers take silicon steel sheets for core stacking, as the number of silicon steel sheets on the rack decreases and the stacking height gradually drops, it will be difficult to pick up the sheets. At this time, a device that can stack silicon steel sheets and can be freely lifted is needed, which can pick up silicon steel sheets more conveniently during the core stacking process.

[0003] The existing lifting equipment for core stacking generally uses a manually adjustable lifting frame or a hydraulic lifting platform. For the manually adjustable lifting frame, it needs to be continuously lifted by a hoisting device, and the operation is relatively cumbersome. It is necessary to continuously adjust the height while carrying out the core stacking work to pick up the silicon steel sheets, which is time-consuming and laborious, greatly reducing the work efficiency, and at the same time increasing the work burden of the workers; while the hydraulic structure lifting platform with high load capacity generally has a large size, and it takes up too much space after being placed, making the operation extremely inconvenient. At the same time, the hydraulic device needs to install a hydraulic pump station separately, with high cost, and also requires high costs for maintenance and repair.

[0004] Therefore, a lifting equipment that is easy to operate and has a small size is needed to be applied to the core manufacturing process to make the entire process of core stacking more efficient. Summary of the Invention

[0005] The utility model provides a miniaturized screw rod lifting platform for transformer core stacking. By a specific single-motor drive mechanism, the screw rod lifters arranged in groups are synchronously controlled to ensure the synchronism of the lifting of the supporting plates on both sides of the platform, and the levelness of the platform is ensured. On the basis of meeting the lifting function, the miniaturized screw rod lifting platform of the utility model has a reduced external dimension and a simplified structure compared with the hydraulic platform, greatly reducing the manufacturing cost; compared with the existing manually adjustable base frame, the automation and simplification of the lifting of the load are realized, reducing the operation difficulty and labor intensity. In addition, by setting a guiding structure, the unstable factors such as the deformation and displacement of the screw rod caused by uneven load for a long time are effectively avoided.

[0006] The technical solution of the utility model is as follows:

[0007] A miniaturized screw lift platform for transformer core stacking includes a screw lift, a T-type steering gear, a motor, a reducer, a base frame, and a support plate; the top of the base frame has a square frame; there are four screw lifts, which are respectively arranged at the four corners of the square frame; the motor and the reducer are arranged on the inner side of the square frame, and the rotating shaft of the motor is connected to the input shaft of the reducer to form a power device; there are two T-type steering gears, which are respectively arranged on two opposite sides of the square frame; the reducer has two output shafts, and the input shafts of the two T-type steering gears are respectively connected to one of the output shafts of the reducer; the T-type steering gear has two output shafts, and the two output shafts of the T-type steering gear are respectively connected to the input shafts of the screw lifts located on both sides thereof; there are two support plates, and each support plate is fixedly connected to the screws of two adjacent screw lifts.

[0008] Compared with the prior art, the utility model realizes the automation and simplification of the lifting of the load when the core is stacked by adopting a new design structure, and reduces the difficulty of operation and labor intensity. The utility model realizes the synchronous operation of the screw lifts arranged in groups through a specific single motor drive mechanism, ensures the synchronization of the two side support plates, and thus ensures the horizontality of the platform. When the core is stacked, the stacked silicon steel sheets are continuously transported upward by the lifting platform of the utility model, which is convenient for the operator to take the sheets, reduces the labor intensity of the workers, and improves the efficiency of the operation. Further, in the aforementioned miniaturized screw lift platform for transformer core stacking, the output shaft of the T-type steering gear is connected to the input shaft of the screw lift through a transmission shaft. Further, the two ends of the transmission shaft are respectively connected to the output shaft of the T-type steering gear and the input shaft of the screw lift through a coupling. The coupling can ensure that the torque is transmitted from the T-type steering gear to the screw lift, and at the same time, it has the characteristics of easy implementation.

[0009] Furthermore, in the aforementioned miniaturized screw lifting platform for transformer core stacking, a guide post is provided on the lower side of the support plate, and correspondingly, a guide post bushing is provided on the base frame; the guide post is inserted into the guide post bushing to form a guide fit. Through the mutual cooperation between the guide post and the guide post bushing, the support plate is constrained, effectively avoiding unstable factors such as screw deformation and displacement caused by long-term uneven load, ensuring that the silicon steel sheets do not fall during the core stacking process, and are smoothly delivered to the workers' working height, protecting the screw lifter from normal operation and reducing equipment damage.

[0010] Furthermore, in the aforementioned miniaturized screw lifting platform for transformer core stacking, the base frame is made of square steel pipes. As the load-bearing foundation of the entire lifting platform, the square steel pipes are made, which have guaranteed strength and are lightweight. At the same time, the inside of the square steel pipes can accommodate the screw rods, which can protect and prevent dust from the screw rods.

[0011] Furthermore, in the aforementioned miniaturized screw lifting platform for transformer core stacking, a group of hooks are provided around the base frame for easy lifting. Therefore, after the lifting platform is loaded, the lifting device can move the lifting platform to the core stacking work area by cooperating with the hooks, which is convenient and practical.

[0012] Furthermore, the aforementioned miniaturized screw lifting platform for transformer core stacking also includes a remote controller for controlling the operation of the motor. During operation, the worker controls the operation of the motor through the remote controller, making the operation of the lifting platform more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The base frame 6 is made of square steel pipes with a size of 1200mm * 550mm and a load-bearing capacity of 5t.
