Description

Technical Field

[0001] The utility model belongs to the field of transformer equipment, and particularly relates to an assembly device for small connecting pipes of an oil tank. Background Art

[0002] In the production and manufacturing of transformer oil tanks and on-site installation processes, the assembly and installation stages are undoubtedly the top priorities in the entire process. This link plays a decisive role in ensuring the stability and safety of the operation of the oil tank. However, both the assembly and installation stages face the problem of fixing the connecting pipes. These connecting pipes, as important components inside the oil tank, carry the key tasks of transporting and conducting transformer oil or other key fluids. However, during the assembly process, due to the large number and diverse sizes and shapes of these connecting pipes, using traditional U-shaped clamps or hose clamps is cumbersome and time-consuming, making the fixing work extremely difficult. Traditional fixing methods often cannot ensure the stability and accuracy of the connecting pipes, resulting in problems such as dimensional deviations from the drawing requirements, non-vertical connecting pipes, and non-horizontal flange surfaces after assembly or installation.

[0003] These problems not only seriously affect the overall appearance and aesthetics of the oil tank, but more importantly, they may pose potential threats to the performance and safety of the transformer. Non-horizontal or non-vertical connecting pipes may cause poor fluid transportation, affecting the heat dissipation and cooling effects of the transformer; while non-horizontal flange surfaces may lead to poor sealing and cause safety hazards such as oil leakage.

[0004] By solving the problem of small connecting pipe assembly, not only can the overall quality of the transformer oil tank be improved, but also the performance and safety of the transformer can be ensured, providing a solid guarantee for the stable operation of the power system. Summary of the Invention

[0005] The purpose of the utility model is to overcome the above problems and provide an assembly device for small connecting pipes of an oil tank, which can accurately adjust the spacing of the small connecting pipes and ensure that the assembly dimensions of the small connecting pipes meet the requirements of the drawings.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The utility model provides an assembly device for small connecting pipes of an oil tank, including a channel-shaped clamp.

[0009] A further improvement of the utility model is that the inner diameter of the nut is the same as the size of the through hole at the end of the channel-shaped clamp.

[0010] A further improvement of the utility model lies in that the nut is a stainless steel nut.

[0011] A further improvement of the utility model lies in that the tightening device is a jacking bolt which is screwed into the nut.

[0012] A further improvement of the utility model lies in that the jacking bolt is a stainless steel bolt.

[0013] A further improvement of the utility model lies in that the opening directions of the embedded grooves on both sides of the grooved clip are the same.

[0014] A further improvement of the utility model lies in that a horizontal limit is welded or pasted at the end of the grooved clip.

[0015] A further improvement of the utility model lies in that the horizontal limit is located below the foldable distance measuring ruler.

[0016] A further improvement of the utility model lies in that the center scale line of the clip is located at the center of the end of the grooved clip.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] By providing embedded grooves on both sides of the grooved clip, the utility model enables the embedded grooves to be stuck on the fuel tank fixing bracket, realizing seamless docking between the grooved clip and the bracket, and tightening and fixing the small connecting pipe through the tightening device at the end of the grooved clip, thus significantly improving the stability and safety of the connection; a measuring ruler locking device is arranged at the end of the grooved clip, and a foldable distance measuring ruler is installed on the measuring ruler locking device. It is possible to read the value on the foldable distance measuring ruler according to the center scale line of the clip set at the end of the grooved clip, and quickly adjust the distance between the small connecting pipes through the data read in real time, ensuring that each connection is accurate and strictly meets the strict requirements of the design drawing.

[0019] Furthermore, a horizontal limit is welded or pasted at the end of the grooved clip, and the horizontal limit can ensure that the foldable measuring ruler maintains the correct angle or position during use, thereby improving the accuracy and stability of data measurement.

[0020] Furthermore, the center scale line of the clip is located at the center of the end of the grooved clip, and the center of the grooved clip is equal to the center of the small connecting pipe. Therefore, setting the center scale line of the clip at the center of the end of the grooved clip can more accurately read the data on the foldable distance measuring ruler.

[0031] The following further describes the present invention in detail with reference to the accompanying drawings:

[0032] As Figure 1 shown, the present invention provides a fuel tank small connecting pipe assembling device, which includes a trough-shaped clamp 1, an embedded groove 2, a tightening bolt 3, a nut 4, a horizontal limit 5, a measuring scale locking device 6, a foldable measuring scale 7, and a clamp center scale line 8. Embedded grooves 2 are opened on both sides of the trough-shaped clamp 1, and the opening directions of the embedded grooves 2 on both sides of the trough-shaped clamp 1 are the same. The embedded grooves 2 are used for fixing with the fuel tank fixing bracket.

[0033] A measuring scale locking device 6 and a tightening device are arranged at the end of the trough-shaped clamp 1. The foldable measuring scale 7 is installed on the measuring scale locking device 6. The measuring scale locking device 6 can easily fix and unlock the foldable measuring scale 7, simplifies the operation process, and improves work efficiency. The foldable measuring scale 7 can be unfolded and folded as needed, and the measuring range can be adjusted as needed, improving the adaptability and flexibility of the device.

[0034] A clamp center scale line 8 is engraved at the center of the end of the trough-shaped clamp 1 for aligning with the scale on the foldable measuring scale 7 to accurately read the measured value.

[0035] A through hole is opened at the end of the trough-shaped clamp 1, and a nut 4 is welded at the through hole. The nut 4 is made of a stainless steel nut. The setting of the nut 4 provides a stable connection point for the subsequent tightening device. At the same time, the nut 4 is made of stainless steel material, has high strength and corrosion resistance, can withstand a large tightening torque, so as to ensure that the small connecting pipe is firmly fixed on the bracket. The stainless steel material has good rust resistance performance, and can maintain its stable performance and is not easily damaged even in a humid or corrosive environment. The use of the stainless steel nut greatly extends the service life of the device.

[0036] The inner diameter of the nut 4 is the same as the size of the through-hole at the end of the grooved clip, and this precise fit ensures that the tightening device can be accurately aligned during installation, avoiding installation errors caused by improper fitting.

[0037] The tightening device is a top bolt 3, which is made of a stainless steel bolt. The top bolt 3 is screwed into the nut 4. Through the combination of the groove 2, the top bolt 3 and the nut 4, the grooved clip 1 can be firmly fixed on the fuel tank fixing bracket, ensuring that the entire device will not loosen or shift during use.

[0038] A horizontal limit 5 is welded or pasted at the end of the grooved clip 1. The horizontal limit 5 is located below the foldable distance measuring ruler 7 and is used to ensure that the foldable distance measuring ruler 7 can maintain a horizontal state during measurement or adjustment, improving the accuracy of measurement.

[0039] As Figure 2 shown, first, the end of the grooved clip 1 and the two side plates are welded and fixed. Embedded grooves 2 with the same opening direction and size are respectively opened on the two side plates of the grooved clip 1. The embedded grooves 2 are fixed on the fuel tank bracket. A through-hole is opened at the end of the grooved clip 1, and the size of the through-hole is the same as the inner diameter of the nut 4. The nut 4 is welded at the through-hole at the end of the grooved clip 1, and the top bolt 3 is screwed into the nut 4. The small union pipe is tightly fixed by rotating the top bolt 3. Then, a measuring ruler locking device 6 is arranged above the nut 4 at the end of the grooved clip 1. The foldable distance measuring ruler 7 is installed on the measuring ruler locking device 6. The horizontal limit 5 is pasted on the grooved clip 1 below the foldable distance measuring ruler 7. A clip center graduation line 8 is set at the center of the end of the grooved clip 1. The foldable distance measuring ruler 7 is placed on the horizontal limit 5 to keep the foldable distance measuring ruler 7 horizontal. After the measuring ruler locking device 6 locks the foldable distance measuring ruler 7, the data is read according to the reading of the clip center graduation line 8 on the foldable distance measuring ruler 7. By reading the data, the distance between the small union pipes can be adjusted to meet the requirements of the drawing dimensions. Through this device, the connection between the small union pipes and the fuel tank is more stable, and the distance between the small union pipes can be set to a fixed value according to requirements, not only meeting the drawing size requirements but also ensuring the safety of the small union pipes after the transformer operates.

[0040] In summary, the fuel tank small connecting pipe assembly device of the present utility model fixes the groove-shaped clamp 1 and the side plate by welding to form a strong support structure, ensuring the stability and reliability during the installation process. The tight fit between the embedded groove 2 and the fuel tank bracket further enhances the firmness of the connection. By setting through holes at the end of the groove-shaped clamp 1, welding nuts 4 and screwing in the tightening bolts 3, precise tightening and fixing of the small connecting pipe are achieved. At the same time, combined with the measuring scale locking device 6, the foldable distance measuring scale 7 and the center scale line 8 of the clamp, the distance between the small connecting pipes can be read and adjusted in real time to ensure compliance with the strict requirements of the design drawings. The design of the entire assembly device takes into account the convenience and efficiency of operation, enabling the installation personnel to quickly and accurately complete the installation and adjustment of the small connecting pipes, improving the production efficiency and product quality.
