Description
Technical Field
[0001] This disclosure relates to the field of current transformer technology, and specifically to a transfer vehicle for current transformers. Background Technology
[0002] Current transformers (CTs) are one of the key devices used for measurement and protection in power systems. Their main function is to convert large currents in the system into standard small currents (usually 5A or 1A) to facilitate connection to measuring instruments, energy meters, relay protection devices, etc.
[0003] Currently, during the production and assembly of current transformers, because there are no lifting points for them, the assembled current transformers must be manually moved to a transfer vehicle. Similarly, when installing the conductive rods, the current transformers must be manually moved onto the porcelain bushings for installation. Since an assembled single-phase circuit breaker weighs approximately 35 kg, the above process requires manual handling of this 35 kg current transformer twice, consuming a significant amount of manpower and posing substantial safety hazards during transport.

[0006] In one possible implementation, the support tube is a hollow circular tube open at both ends, so that the conductive rod passes through the support tube and is mounted on the current transformer.
[0007] In one possible implementation, the flipping support structure further includes: A power-assisted cylinder, one end of which is connected to the cylinder mounting shaft on the transfer vehicle frame, and the other end is connected to the bottom of the support plate.
[0008] In one possible implementation, the rotating shaft component includes: Two bearings are fixed to the two bearing seats of the transfer vehicle frame; A rotating shaft is connected to the two bearings.

[0023] In the following, exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings to enable those skilled in the art to readily implement them. Furthermore, for clarity, portions unrelated to the description of exemplary embodiments have been omitted from the drawings.
[0024] In this disclosure, it should be understood that terms such as “comprising” or “having” are intended to indicate the presence of features, figures, steps, behaviors, components, parts or combinations thereof disclosed in this specification, and do not preclude the possibility of the presence or addition of one or more other features, figures, steps, behaviors, components, parts or combinations thereof.
[0025] It should also be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0026] Figure 1 This diagram illustrates the structure of a transport vehicle for a current transformer according to an embodiment of this disclosure. Figure 1 As shown, the assembly device includes a transfer frame 1, multiple wheels 2, and at least one tilting support structure 3.
[0027] like Figure 1 As shown, the bottom of the transfer vehicle frame 1 is equipped with four wheels 2. Of course, in other embodiments, the wheels 2 can be three, six, etc., and there is no limitation here. When the wheels 2 roll under the action of force, they can drive the transfer vehicle to move.
[0028] There can be one or more of the flip-over support structure 3, and each flip-over support structure 3 can transport one current transformer. Figure 1 There are three transfer carts shown. In other embodiments, there can be one, five, etc., of each flip support structure 3. Each flip support structure 3 includes a rotating shaft component 31 and a support plate 32 connected to the rotating shaft component 31. The rotating shaft component 31 is fixed on the transfer cart frame 1. The support plate 32 is flipped by the rotating shaft component 31. A support tube 33 is provided on the support plate 32. When the transfer cart is used to transfer the current transformer, the support plate 32 of the flip support structure 3 can be flipped 90° to make the support tube 33 on the support plate 32 horizontal. Then, the support tube 33 is aligned with the inner hole of the current transformer and inserted. The transfer cart is brought close to the assembly device of the current transformer. The support plate 32 is held with one hand and the bottom of the current transformer is held with the other hand. The support plate 32 is flipped 90° and the current transformer is moved onto the support plate 32 of the transfer cart. In this way, multiple current transformers can be moved onto multiple support plates 32 of the transfer cart in sequence and transferred to the next work station.
[0029] The transfer vehicle provided in this embodiment includes a transfer frame 1, wheels 2 located at the bottom of the transfer frame 1, and at least one tilting support structure 3 located above the transfer frame 1. The tilting support structure 3 includes a rotating shaft component 31 and a support plate 32 connected to the rotating shaft component 31. The rotating shaft component 31 is fixed to the transfer frame 1, and the support plate 32 is tilted by the rotating shaft component 31. A support tube 33 is provided on the support plate 32. In this way, when transferring the current transformer, the support plate 32 can be tilted so that the support tube 33 is parallel, and then the device can be loaded. After the current transformer is assembled on the mounting device and placed horizontally, it is fitted onto the support tube 33. The support plate 32 is flipped so that the current transformer fitted onto the support tube 33 is in a vertical state, thus removing the current transformer from the mounting device. Then, the transfer cart can be pushed, and the rolling wheels 2 can be used to transfer the current transformer to the next work station, realizing the transfer of the current transformer. This saves manpower and avoids safety hazards during the handling process. Moreover, the transfer cart provided in this embodiment can be designed with different specifications according to the specifications and dimensions of the current transformer, realizing the transfer and assembly operations of various current transformers, and has strong versatility.
[0030] Figure 2 This diagram illustrates a tilting support structure for a transfer vehicle according to an embodiment of the present disclosure. Figure 3 This diagram shows a structural schematic of a current transformer transfer vehicle according to an embodiment of the present disclosure in use. Figure 4 This diagram illustrates the structure of a rotating shaft component of a transfer vehicle according to an embodiment of the present disclosure. Figure 5 This diagram illustrates the structure of a transfer carriage for a current transformer according to an embodiment of this disclosure. The following is in conjunction with... Figures 2-5 The transfer vehicle provided in this embodiment will be described in detail.
[0031] In one possible implementation, such as Figure 2 As shown, the support tube 33 is a hollow round tube with openings at both ends, so that the conductive rod can pass through the support tube 33 and be installed on the current transformer. In this way, when the transfer vehicle transports the current transformer to the next process, the conductive rod can be passed through the support tube 33 and installed on the current transformer on the transfer vehicle, providing a tooling platform for the assembly of the conductive rod in the next process.
[0032] In one possible implementation, such as Figure 3 As shown, the flipping support structure 3 also includes a booster cylinder 34.
[0033] This power-assisted cylinder (also known as an auxiliary cylinder, power cylinder, or pneumatic power-assist device) is a pneumatic actuator that uses compressed air as a power source to help operators reduce operating force and improve work efficiency. For example... Figure 3As shown, one end of the power-assisted cylinder is connected to the cylinder mounting shaft 11 on the transfer frame 1 (reference). Figure 5 The other end is connected to the mounting base 321 at the bottom of the support plate 32 (see reference). Figure 2 When the support plate 32 is flipped so that the current transformer sleeved on the support tube 33 is in a vertical position, the assist cylinder can play a buffering role because the current transformer is heavy, thus preventing the current transformer on the support plate 32 from being bumped.
[0034] In one possible implementation, such as Figure 4 As shown, the rotating shaft component 31 includes: Two bearings 311 are fixed on the two bearing seats 12 of the transfer frame 1; The rotating shaft 312 is connected to the two bearings 311; Two bearing end caps 313 are provided to fix the two bearings 311 onto the two bearing seats 12 of the transfer frame 1, respectively, and are located on the outside of the bearing seats 12. The bearing end caps 313 can protect the bearings 311 and prevent external dust, moisture, grease and other impurities from entering the bearings 311 and causing premature damage to the bearings 311.
[0035] In one possible implementation, such as Figure 4 As shown, the rotating shaft component 31 also includes a shaft end cover 314, which is a cover for mounting the end of the rotating shaft 312 and is mainly used for sealing the shaft end hole, dust prevention, decoration, or safety protection.
[0036] In one possible implementation, refer to Figure 1 , Figure 4 and Figure 5 The bearing seat 12 is located on the side of the transfer frame 1; the support plate 32 is located above the transfer frame 1, and the support plate 32 is connected to the rotating shaft 312 of the rotating shaft component 31 through the fixing tube 322.
[0037] In one possible implementation, such as Figure 5 As shown, the transfer frame 1 includes a square tube frame 13 and a plurality of mounting plates 14. The mounting plates 14 are located at the bottom of the square tube frame 13 and are used to mount the wheels 2.
[0038] In one possible implementation, such as Figure 2 As shown, the support plate 32 is provided with a handle 323. When flipping the support plate 32, the operator can apply force through the handle 323 to facilitate the flipping of the support plate 32.
[0039] In one possible implementation, the wheel 2 is a swivel wheel. The swivel wheel (also called a caster or steering wheel) is a wheel that can rotate freely 360 degrees. The swivel wheel can be connected to the mounting plate 14 through a rotating mechanism, so that the transport vehicle can easily move forward, backward, turn, or even rotate in place on the ground, which greatly improves the convenience and efficiency of the transport vehicle's movement.
[0040] In one possible implementation, the caster wheel also includes a braking device for locking the wheel's rotation or the entire steering mechanism, improving safety. When unloading the current transformer from the assembly device, the transfer cart 1 can be moved to the assembly device, the support plate 32 can be flipped to make the support tube 33 parallel, and the horizontally placed current transformer, assembled on the assembly device, can be fitted onto the support tube 33. Then, the braking device is activated, and the fixing fixture secures the transfer cart to the assembly device, thus safely unloading the current transformer. The braking device can also be activated when installing the conductive rod to prevent the transfer cart from moving, ensuring the safe installation of the conductive rod.
[0041] Example, Figure 6 This diagram illustrates a current transformer located on an assembly device according to an embodiment of the present disclosure. Figure 7 This diagram illustrates a process for removing, transferring, and assembling a current transformer according to an embodiment of this disclosure. Specifically, the process may include the following steps: Step S1, Reference Figures 1-6 ,like Figure 7 As shown in the figure above, the support plate 32 of the flip support structure 3 is flipped 90° so that the support tube 33 on the support plate 32 is in a horizontal state. Then, the support tube 33 is aligned with the inner hole of the current transformer on the assembly device (refer to...). Figure 6 Insert the transfer cart into the assembly device of the current transformer and use the fixing fixture 4 to fix the transfer cart to the assembly device. In this way, you can hold the handle 323 of the support plate 32 with one hand and the bottom of the current transformer with the other hand, rotate the support plate 32 90° and move the current transformer onto the support plate 32 of the transfer cart. Step S2, as follows Figure 7 As shown in the middle figure, after the three current transformers are moved to the three support plates 32 of the transfer vehicle in sequence according to the method of step S1, these current transformers can be transferred to the next work station. Step S3, as follows Figure 7 As shown in the figure below, after these current transformers are transferred to the next workstation, a conductive rod can be passed through the support tube 33 and installed on the current transformer. After the conductive rod is installed, since there are metal parts on the conductive rod, lifting points can be set up for subsequent hoisting and transportation.

Those skilled in the art should understand that the scope of the invention involved in this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept.
