Description

Technical Field

[0001] This utility model belongs to the field of current transformer transfer technology, specifically, it relates to a current transformer transfer device. Background Technology

[0002] Instrument transformers, also known as instrument transformers, are a general term for current transformers and voltage transformers. They can transform high voltage into low voltage and large current into small current, and are used in measurement or protection systems. As the core equipment for realizing current measurement, protection and metering functions in power systems, current transformers are widely used in substations, power plants and industrial power distribution systems.

[0003] Chinese Patent No. CN212099018U discloses a transfer vehicle for the production of current transformers, including a vehicle base, a support platform, a current transformer fixing assembly disposed on the support platform, and a push rod fixedly connected to the vehicle base. The support platform is arranged parallel to the vehicle base and a shock absorber is disposed between it. The current transformer fixing assembly includes baffles disposed on the front and rear sides of the support platform, fixed rods disposed between the baffles and located on the left and right sides above the support platform, a movable rod mounted between the fixed rods and movable along the fixed rods, and a fixed plate sleeved on the movable rod.

[0004] Although the above-mentioned device can fix the current transformer by means of threaded connection, it is necessary to fix it by rotating the fixing plate every time the current transformer is transferred and installed. When there are many current transformers to be transported, it is easy to increase the workload of the staff and is not conducive to the long-term use of the current transformers.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a current transformer transfer device, which solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] A current transformer transfer device, comprising:

[0009] The transfer vehicle has an installation frame on its upper side, and multiple placement plates are slidably fitted on both sides of the inner wall of the installation frame. Multiple fixing mechanisms are installed on the placement plates.

[0010] The fixing mechanism includes multiple shelves that slide on the placement plate, multiple movable blocks that slide on the placement plate, and fixed plates that are elastically fitted on opposite sides of two adjacent movable blocks. A movable plate is installed on one side of the placement plate, and multiple control blocks are installed on one side of the movable plate. The movable blocks and control blocks cooperate with each other. A control component is installed on one side of the placement plate, and the control component cooperates with the movable blocks.

[0011] Optionally, multiple buffers are installed between the transport vehicle and the mounting frame.

[0012] Optionally, the control component includes a threaded rod threaded onto the mounting bracket, with a bearing mounted at one end of the threaded rod and the bearing fixed to one side of the movable plate.

[0013] Optionally, an elastic telescopic rod is installed on one side of the movable block, one end of which is connected to the fixed plate, and a guide block is installed on one end of the elastic telescopic rod. The guide block cooperates with the control block. An arc-shaped guide groove is provided on one side of the control block, and the arc-shaped guide groove cooperates with the guide block.

[0014] Optionally, a T-shaped block is fixed to the lower side of the movable block, and a T-shaped groove is provided on the placement frame, with the T-shaped block cooperating with the T-shaped groove.

[0015] Optionally, both ends of the placement rack are fixed with sliding frames, and one side of the sliding frame is threaded with a set screw, which engages with the placement plate.

[0016] Optionally, multiple sliding grooves are provided on both sides of the inner wall of the mounting frame, and sliders are fixed on both sides of multiple placement plates, with the sliders cooperating with the sliding grooves.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] The fixed plates, under the action of elasticity, help workers to complete the initial positioning of the current transformers. This not only reduces the initial fixing steps for individual current transformers but also reduces the workload of workers, making the operation of the transfer device more convenient and faster. The control block and moving block, driven by the control component, can push the moving block to move, thereby bringing two adjacent fixed plates closer together. This increases the clamping force of the fixed plates on the current transformers and allows for simultaneous positioning of current transformers in all fixed plates, improving the operability of fixing the current transformers. The placement racks can be flexibly adjusted according to the size of the current transformers, thus adapting to various specifications of current transformers and increasing the versatility of the transfer device.

Detailed Implementation

[0032] The present invention will now be described in further detail with reference to the accompanying drawings.

[0033] Please see Figures 1-6 As shown, this embodiment provides a current transformer transfer device, including:

[0034] The transfer vehicle 1 has an installation frame 101 mounted on its upper side. Multiple placement plates 102 are slidably fitted on both sides of the inner wall of the installation frame 101. Multiple fixing mechanisms 2 are installed on the placement plates 102.

[0035] The fixing mechanism 2 includes multiple placement racks 201 that are slidably fitted on the placement plate 102. Multiple moving blocks 202 are slidably fitted on the placement racks 201. Fixed plates 203 are elastically fitted on opposite sides of two adjacent moving blocks 202. A moving plate 204 is installed on one side of the placement rack 201. Multiple control blocks 205 are installed on one side of the moving plate 204. The moving blocks 202 cooperate with the control blocks 205. A control component 3 is installed on one side of the placement rack 201. The control component 3 cooperates with the moving blocks 202.

[0036] When in use, first open the two fixed plates 203. Because the fixed plates 203 are elastically fitted on one side of the moving block 202, when the operator is fixing the current transformer, he can first manually pry open the two fixed plates 203, so as to use the elastic force to complete the initial positioning of the current transformer.

[0037] After all the current transformers are initially positioned, the moving plate 204 is first moved by the control unit 3. The movement of the moving plate 204 will drive multiple control blocks 205 to move. Two adjacent control blocks 205 will move in groups towards two adjacent moving blocks 202, thereby driving the two adjacent moving blocks 202 to move closer to each other. This will drive the two fixed plates 203 to move towards the current transformers, thereby improving the stability of the fixed plates 203 in holding the current transformers, so as to facilitate the subsequent transfer of the current transformers.

[0038] The fixed plate 203, under the action of elasticity, can help the staff complete the initial positioning of the current transformer. This not only reduces the initial fixing steps of a single current transformer but also reduces the workload of the staff, making the operation of the transfer device more convenient and faster. The control block 205 and the moving block 202, driven by the control component 3, can cause the control block 205 to squeeze and move the moving block 202, thereby bringing two adjacent fixed plates 203 closer together. This increases the clamping force of the fixed plate 203 on the current transformer and allows for the simultaneous positioning of all current transformers in the fixed plates 203, improving the operability of the current transformer during fixing. The placement rack 201 can be flexibly adjusted according to the size of the current transformer, thus adapting to various specifications of current transformers and increasing the versatility of the transfer device.

[0039] In this embodiment, multiple buffers 103 are installed between the transfer vehicle 1 and the mounting frame 101. By using the multiple buffers 103, the vibration generated by the transfer vehicle 1 when transporting the current transformer can be absorbed by its elastic deformation. This can reduce the impact of vibration caused by uneven road surface or start-stop during the transfer process on the mounting frame 101 and the current transformer, and reduce problems such as loose parts and damage to internal components of the current transformer due to severe vibration.

[0040] In this embodiment, the control component 3 includes a threaded rod 301 threaded onto the placement frame 201. A bearing 302 is mounted at one end of the threaded rod 301 and is fixed to one side of the moving plate 204. By rotating the threaded rod 301, the moving plate 204 can be moved, thereby adjusting the clamping force of the adjacent two fixed discs 203 on the current transformer. This allows for secondary fixing of the current transformer, improving stability and enabling the positioning of multiple current transformers.

[0041] In this embodiment, a flexible telescopic rod 206 is installed on one side of the movable block 202. One end of the flexible telescopic rod 206 is connected to the fixed disk 203, and a guide block 207 is installed on one end of the flexible telescopic rod 206. The guide block 207 cooperates with the control block 205. In this embodiment, an arc-shaped guide groove 208 is provided on one side of the control block 205, and the arc-shaped guide groove 208 cooperates with the guide block 207. Through the cooperation of the arc-shaped guide groove 208 and the guide block 207, the smooth guiding effect of the arc surface can be used to convert the linear movement of the control block 205 into the opening and closing action of the movable block 202, thereby controlling the synchronous adjustment of multiple fixed disks 203. This reduces the need for individual operation of each current transformer, reducing the workload of the staff. At the same time, the elastic deformation of the flexible telescopic rod 206 can also buffer the current transformers in the fixed disk 203, preventing the current transformers from being over-clamped.

[0042] In this embodiment, a T-shaped block 209 is fixed to the lower side of the movable block 202, and a T-shaped groove 210 is provided on the placement frame 201. The T-shaped block 209 cooperates with the T-shaped groove 210. The T-shaped groove 210 can limit and guide the movement of the T-shaped block 209, thereby improving the stability of the fixed plate 203 on the movable block 202 when it moves.

[0043] In this embodiment, both ends of the placement frame 201 are fixed with sliding frames 211. One side of the sliding frame 211 is threaded with a set screw 212, which engages with the placement plate 102. Specifically, the upper side of the placement plate 102 is provided with multiple guide grooves, and the lower side of the sliding frame 211 is fixed with a guide slider, which engages with the guide grooves. Through the sliding frame 211, the placement frame 201 can be moved on the placement plate 102. Under the limiting guidance of the guide grooves and the guide slider, the stability of the placement frame 201 is improved, and the distance between two adjacent placement frames 201 can be adjusted. This allows for the fixing of current transformers of various sizes, and the placement frame 201 can be positioned after movement using the set screw 212.

[0044] In this embodiment, the inner walls of the mounting frame 101 are provided with multiple sliding grooves 104 on both sides, and multiple placement plates 102 are fixed with sliders 105 on both sides, with the sliders 105 cooperating with the sliding grooves 104. Specifically, multiple fixing members are installed on one side of the mounting frame 101, and the fixing members cooperate with the sliders 105. By using the sliders 105, the placement plates 102 inside the mounting frame 101 can be pulled out, which facilitates the fixing of the current transformers by the operators. Moreover, the fixing members can position the placement plates 102 that have slid into the mounting frame 101, reducing the possibility of the placement plates 102 containing the current transformers sliding out during operation. In this embodiment, the fixing members can be the elastic positioning rods or positioning pins in the prior art. The choice can be made according to actual needs without affecting the normal use of this application, and there is no limitation on this.

[0045] The upper side of the fixed plate 203 in this embodiment is provided with an arc-shaped surface. By using the arc-shaped surface, when the current transformer is initially installed, the operator can complete the initial positioning of the current transformer without manually opening the fixed plate 203 by squeezing the arc-shaped surface, which can improve the operator's operability.
