Abstract
Description
Technical Field
[0001] This utility model belongs to the field of lifting tool technology, and in particular relates to an anti-slip C-type lifting tool suitable for transformer iron ferrite chips. Background Technology
[0002] In the field of power equipment manufacturing, transformer ferrite cores are a core component of transformers, making their efficient and precise hoisting and installation particularly important. Traditionally, a cleverly designed and uniquely shaped lifting tool—the C-type lifting tool—is widely used for ferrite core hoisting operations. Named for its resemblance to the letter "C," this tool not only demonstrates intuitive and visual appeal but also exhibits significant advantages in practical applications. The C-type lifting tool boasts a simple yet rational structural design, achieving flexibility and convenience during the hoisting process through ingenious mechanical principles.
[0003] However, with the continuous advancement of technology in the power industry and the increasing diversification of product demands, the specifications and models of transformer ferrite laminations are showing a trend of diversification. This change poses a greater challenge to the adaptability of C-type lifting tools. Due to differences in weight distribution, size, and center of gravity among different specifications and models of ferrite laminations, traditional C-type lifting tools often struggle to ensure absolute balance and stability during the lifting process when handling these new types of ferrite laminations. When the center of gravity of the ferrite lamination cannot be completely aligned with the center of gravity of the C-type lifting tool, it may cause the lifting tool to tilt, thereby threatening the safety of the lifting operation and even leading to safety accidents.
[0004] Therefore, in order to address the problems existing in the C-type lifting tool when lifting ferrous metal assemblies, it is necessary to innovate and optimize its design to improve its adaptability and safety, and meet the urgent needs of the power industry for efficient and safe lifting of transformer ferrous metal assemblies. Summary of the Invention
[0005] To address the shortcomings of the existing technology, this utility model provides a novel anti-slip C-type lifting tool suitable for various specifications of ferrous briquettes. The technical solution of this utility model to solve the technical problem is: A C-type lifting device with anti-slip features a C-type lifting device body. An upper crossbeam is provided on the upper part of the C-type lifting device body. A hydraulic cylinder, a hydraulic pump, a wireless signal receiver, a battery pack, and a charging mechanism are fixedly installed on the upper crossbeam of the C-type lifting device body. The battery pack in the battery pack and charging mechanism is electrically connected to the hydraulic pump. The hydraulic cylinder and the hydraulic pump are connected through a pipeline. A pressure plate is fixedly installed on the piston end of the hydraulic cylinder. The wireless signal receiver is electrically connected to the hydraulic cylinder for communication. The remote control is wirelessly connected to the wireless signal receiver for communication.
[0006] Preferably, an epoxy glass cloth insulation board is fixedly installed on the surface of the pressure plate.
[0007] The beneficial effects of this utility model are: This invention applies constant pressure to the iron chip by adding a series of innovative improvements, such as a hydraulic pump, hydraulic cylinder, wireless signal receiver, and remote control. This solves the tilting problem of existing C-type lifting tools during the lifting process, improves the stability and reliability of iron chip lifting operations, and provides a safer and more efficient solution for the manufacturing and installation of power equipment.

Detailed Implementation
[0009] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.
[0010] like Figure 1-4 As shown, an anti-slip C-type lifting device includes a C-type lifting device body 1. An upper crossbeam is provided on the upper part of the C-type lifting device body 1. A hydraulic cylinder 2, a hydraulic pump 3, a wireless signal receiver 4, and a battery pack and charging mechanism 6 are fixedly installed on the upper crossbeam of the C-type lifting device body 1. A pressure plate 5 is fixedly installed on the hydraulic cylinder 2. The hydraulic cylinder 2, hydraulic pump 3, wireless signal receiver 4, and battery pack and charging mechanism 6 can be fixedly installed on the upper crossbeam of the C-type lifting device body 1 by using bolts, nuts, or other connecting parts through mounting holes in the upper crossbeam. The pressure plate 5 can also be fixedly installed on the hydraulic cylinder 2 using bolts, nuts, or other connecting parts.
[0011] Hydraulic cylinder 2 and hydraulic pump 3 are connected by pipelines. Hydraulic pump 3 provides constant pressure to hydraulic cylinder 2. Hydraulic cylinder 2 can be a flange cylinder: 50 / 60 / 30 / 430, power unit: 24V / 800W / 1.0.
[0012] The present invention provides an anti-slip C-type lifting device, the specific implementation method of which is as follows: 1. A small hydraulic cylinder 2 and a hydraulic pump 3 are configured on the upper crossbeam of the C-type lifting device body 1 to form a hydraulic system. The pressure of the hydraulic pump 3 is adjustable, which can meet the clamping force requirements of the iron chip. According to the lifting height of the iron chip, the hydraulic cylinder 2 is selected as a flange cylinder 50 / 60 / 30 / 430 with an inner diameter of 50mm and a stroke of 430mm. Through the constant pressure provided by the hydraulic pump 3, the hydraulic cylinder 2 applies a pressure of about 0.1MPa to the iron chip to ensure its lifting safety.
[0013] 2. A 3mm thick pressure plate 5 is fixedly installed at the bottom of the piston of hydraulic cylinder 2, and a 1mm thick epoxy fiberglass cloth insulation board is added between the pressure plate 5 and the iron chip to prevent the pressure plate 5 from directly contacting the iron chip. (The epoxy fiberglass cloth insulation board is attached to the pressure plate 5 with strong adhesive.)
[0014] 3. A wireless signal receiver 4 is installed on the upper crossbeam of the C-type lifting device body 1. Wireless remote control is used; the operator communicates wirelessly with the receiver 4 via a remote control, and then controls the clamping and disengaging functions of the hydraulic cylinder 2 (clamping refers to the piston of the hydraulic cylinder 2 moving downwards, disengaging refers to the piston of the hydraulic cylinder 2 moving upwards). The remote control distance is ≥50 meters, and the remote control is an industrial rugged remote control. The wireless signal receiver 4 is model YDF-4AS, and the remote control is a universal remote control. The wireless signal receiver 4 is wired to the hydraulic cylinder 2, sending electrical signals to control its movement.
[0015] 4. A battery pack and charging mechanism 6 are installed on the upper crossbeam of the C-type lifting device body 1. The battery pack capacity is sufficient for 8 hours of continuous operation or ≥120 continuous operations of the hydraulic cylinder 2. The battery pack voltage is 48V, and a complete set of battery pack charging equipment is provided. The battery pack is fixedly installed on the upper crossbeam of the C-type lifting device body 1 via a battery pack mounting bracket. The battery pack mounting bracket is a steel plate frame that can be completely disassembled. The battery pack supplies power to the hydraulic pump 3, and the hydraulic pump 3 provides constant pressure to the hydraulic cylinder 2.
[0016] The anti-slip C-type lifting tool provided in this embodiment of the utility model can be applied to the lifting of transformer ferrite chips. By applying a constant pressure of 0.1MPa to the ferrite chips through the hydraulic system, the ferrite chips are kept stable during the lifting process, which can effectively prevent the ferrite chips from slipping during the lifting process and ensure the safety of the ferrite chip lifting operation.
[0017] In this embodiment of the utility model, all technical features not described in detail are existing technologies or conventional technical means, and will not be repeated here.
[0018] Finally, it should be noted that the above embodiments are merely specific implementations of this utility model, used to illustrate the technical solution of this utility model, and not to limit it.
