Description

Technical Field

[0001] The invention relates to the technical field of power transformer core processing equipment, in particular to an ultra-high voltage core automatic turning platform. Background Art

[0002] In the prior art, the core stacking platform consists of two parts, one is a stacking platform used for stacking alone, and the other is a fixed flipping mechanism that cooperates with the stacking platform. Currently, the flipping mechanism can only be lifted and assembled on the stacking platform by a crane before flipping. The crane flipping requires a large hoist, which is heavy, has a high operating risk factor, and is inefficient. The electric drive mode causes the flipping platform to be unable to flip large transformer cores, and related components are easily worn and damaged, with poor safety. At the same time, the continuous application of external force to the core product by the crane flipping will affect the appearance, size and performance of the product. Summary of the invention

[0003] In view of the shortcomings in the above-mentioned existing production technology, the applicant provides a reasonably structured ultra-high voltage core automatic flipping platform, which can realize the automatic flipping function through a single device, without the use of a crane, reducing the consumption of lifting equipment, solving the problems of unsafe flipping by the crane and the fragile and unsafe components of the electric flipping machine, eliminating the impact on product quality caused by the external force exerted by the crane equipment on the product, and making the operation safe and convenient, thereby improving operating efficiency and product quality.

[0004] The technical solution adopted by the present invention is as follows:

[0005] An automatic flipping platform for ultra-high voltage iron cores comprises two bases arranged in parallel at intervals, the upper surfaces of the two bases are respectively connected to a movable frame plate by rotation through a rotating shaft, and a bearing frame is integrally connected between the two movable frame plates; the movable frame plates are in a triangular structure, the two movable frame plates are symmetrically arranged, and a connecting rod driving mechanism is installed on each movable frame plate, which drives the movable frame plate to flip around the rotating shaft located at one top end thereof, and the rotating shaft is located at one end of the triangle close to the connection between the base and the bearing frame; the two bases and the bearing frame form a U-shaped frame body structure; a lifting platform is installed on one side of the bearing frame located inside the opening of the U-shaped frame body structure.

[0006] As a further improvement of the above technical solution:

[0008] The cylinder end of the long hydraulic cylinder is installed in the movable frame plate through the second rotating shaft.

[0009] A guide rail with side grooves is arranged on one side of the movable frame plate located inside the opening of the U-shaped frame structure.

[0010] An adjusting screw rod is installed on the top surface of the guide rail, and a travel sensing switch is installed on the sliding block that cooperates with the adjusting screw rod for transmission.

[0011] A handle is arranged at one end of the adjusting screw rod.

[0012] It also includes a hydraulic pump station for providing hydraulic power to a driving device for driving the lifting platform to move up and down in the U-shaped frame structure.

[0016] The present invention has strong operational mobility, realizes an assembly line operation mode, improves operating efficiency and production flexibility, reduces professional skill requirements for employees, reduces operating intensity, and improves operating efficiency, product quality and safety.

[0017] The present invention has the function of automatically flipping various iron cores at one time, without the need for manual crane operation and manual preparation work before flipping, thus avoiding the cumbersomeness and high risk of crane flipping operation and quality problems caused by impact on products.

[0023] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, Figure 1 As shown, the ultra-high voltage core automatic flipping platform of this embodiment includes two bases 1 arranged in parallel at an interval, and the upper surfaces of the two bases 1 are rotatably connected to a movable frame plate 12 through a rotating shaft 3, and a supporting frame 4 is integrally connected between the two movable frame plates 12; the movable frame plates 12 are in a triangular structure, and the two movable frame plates 12 are symmetrically arranged, and a connecting rod driving mechanism is installed on each movable frame plate 12, which drives the movable frame plate 12 to flip around the rotating shaft 3 located at one top end thereof, and the rotating shaft 3 is located at one end of the triangle close to the base 1 and the supporting frame 4; the two bases 1 and the supporting frame 4 form a U-shaped frame body structure; the supporting frame 4 is located on one side of the opening of the U-shaped frame body structure and a lifting platform 5 is installed.

[0025] The structure of the connecting rod driving mechanism is as follows: a long hydraulic cylinder 7 is fixedly installed inside the movable frame plate 12 along one oblique side direction, a short hydraulic cylinder 6 is installed outside the movable frame plate 12 along another oblique side direction, a rotating shaft 3 is provided at one end of the other oblique side, and the other end is a hinged end, and a connecting rod block 13 is provided in the hinged end; the cylinder end of the short hydraulic cylinder 6 is hinged to the base 1 through a first rotating shaft 61, and the piston rod heads of the short hydraulic cylinder 6 and the long hydraulic cylinder 7 are respectively connected to the end of the movable frame plate 12 through a first hinge shaft 62 and a second hinge shaft 71 installed in the connecting rod block 13, and the first hinge shaft 62 and the second hinge shaft 71 are arranged parallel and adjacent in the connecting rod block 13.

[0026] The cylinder end of the long hydraulic cylinder 7 is installed in the movable frame plate 12 through the second rotating shaft 72.

[0027] like Figure 3 As shown, a guide rail 8 with a side groove is provided on one side of the movable frame plate 12 located inside the opening of the U-shaped frame structure.

[0028] An adjusting screw rod 14 is installed on the top surface of the guide rail 8, and a travel sensing switch 9 is installed on the slider that cooperates with the adjusting screw rod 14 in transmission.

[0029] One end of the adjusting screw rod 14 is provided with a handle.

[0030] It also includes a hydraulic pump station 2 for providing hydraulic power to a driving device for driving the lifting platform 5 to move up and down in the U-shaped frame structure.

[0031] A safety grating 10 and an operating screen 11 are installed outside the U-shaped frame structure.

[0032] The working process of the ultra-high voltage core automatic turning platform of this embodiment is as follows:

[0033] The air cushion handling equipment sends the stacking table (not shown in the figure) carrying the iron core into the U-shaped frame body structure. Guides that cooperate with the guide rails 8 are provided on both sides of the stacking table. After being sent to the position, the lifting platform 5 is driven by a driving device installed on the load-bearing frame 4 and provided with a hydraulic source by the hydraulic pump station 2. It automatically rises and supports the lower yoke pad of the iron core on the stacking table. The handle is shaken until the stroke sensing switch 9 presses the stacking table tightly. The stroke sensing switch power supply 9 is turned on, and the connecting rod drive mechanism works: the long hydraulic cylinder 7 extends, and the short hydraulic cylinder 6 retracts. The three-link mechanism is formed by the long hydraulic cylinder 7, the connecting block 13, and the short hydraulic cylinder 6, so that the movable frame plates 12 on both sides simultaneously use their respective rotating shafts 3 as the rotation center to complete the flipping process from lying flat to standing up. The flipping state is detailed in Figure 3The stacking platform is located between the movable frame plates 12 on both sides, so that the stacking platform can be turned 90 degrees. When the two movable frame plates 12 are turned, the middle bearing frame 4 is connected to the two movable frame plates 12 in an integrated manner through a connecting cross arm or a connecting beam (not shown in the figure), so it also rotates synchronously with the movable frame plates 12 to ensure that the lower yoke pad of the core is firmly fixed during the turning process. If any object breaks into the turning area during the turning process, the safety grating 10 automatically senses and cuts off the power supply to stop the operation and automatically locks the hydraulic system to stop. The command input operation can be conveniently performed through the operation screen 11.
