Description

Technical Field

[0001] This utility model belongs to the field of power transmission and transformation equipment transportation technology, and specifically refers to a bushing transportation tool. Background Technology

[0002] Bushings, as a key component of power transmission and transformation equipment, are widely used in GIS, circuit breakers, transformers, instrument transformers, and various incoming and outgoing line equipment due to their excellent insulation performance and maintenance-free operation. They play multiple important roles, including support, insulation, and protection. Given the high cost of bushings, strict requirements are imposed on their transportation to avoid unnecessary economic losses and safety accidents. During transportation, bushings must not be subjected to impacts or improper stress, otherwise damage may occur.

[0003] In existing technologies, all components of the bushing (including the body, upper and lower flanges, etc.) are typically assembled into a single unit, and then one or more bushings are packaged and transported according to the installation requirements at the construction site. Specifically, the transportation company builds a wooden frame at the assembly site based on the actual shape and size of the product. The wooden frame protects the bushing during transportation, preventing shaking, dust from entering the bushing, and debris such as gravel from damaging the insulation. However, the shape and size of bushings required by different customers are not exactly the same, resulting in the wooden frames being essentially disposable items, yet incurring high manufacturing costs. Furthermore, the wooden frames have limited strength and cannot be stacked during transportation, leading to high vehicle costs even when transporting a large number of bushings. In summary, the existing bushing transportation method results in excessively high transportation costs, placing a significant burden on manufacturers. Utility Model Content

Detailed Implementation

[0028] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0029] refer to Figures 1 to 11 As shown, this utility model discloses a sleeve transport fixture, including a plurality of sleeves 1 to be transported, a plurality of end frames 2 for fixing the ends of the sleeves 1 to form a sleeve array 100, and end cover plates 3 and diagonal tie rods 4. Several upper flange holes 11 and lower flange holes 12 are respectively provided at both ends of the sleeve 1; in the sleeve array 100, the upper and lower adjacent sleeves 1 and the left and right adjacent sleeves 1 are arranged in an alternating manner, that is, one sleeve is positioned at 0° and the adjacent sleeves are not horizontally rotated 180° before being placed. The end frame 2 includes four rectangular side rods 21 (preferably square). The length of the side rods 21 is not less than the maximum outer diameter of the sleeve 1, which can prevent adjacent sleeves in the sleeve array 100 from contacting each other, thereby avoiding bumps and friction during transportation. Both ends of the side rods 21 are provided with first waist holes 211, which are arranged along the length direction of the side rods 21. The side rods 21 on the left and right sides are integrally connected with horizontally extending fixing rods 22. The fixing rods 22 are provided with second waist holes 221 and third waist holes 222. The second waist holes 221 are arranged along the left and right direction and are located at the end where the two fixing rods 22 are close to each other. The third waist holes 222 are arranged along the up and down direction and are located at the end where the two fixing rods 22 are opposite to each other. The end cover plate 3 is a circular cover plate that matches the lower end face of the sleeve 1, and it is provided with a cover plate through hole 31 that is opposite to the lower flange hole 12. During assembly, adjacent end frames 2 are secured by bolts passing through opposite first waist holes 211 to form two frame arrays 200 located at both ends of the sleeve array 100; the upper end of the sleeve 1 is secured to the opposite end frame 2 by bolts passing through opposite second waist holes 221 and upper flange holes 11; the lower end of the sleeve 1 is secured to the opposite end frame 2 by bolts passing through opposite third waist holes 222, cover plate through holes 31 and lower flange holes 12, and the end cover plate 3 covers the lower end of the sleeve 1; on the side of the sleeve array 100, the lowermost end frame 2 at one end and the lowermost end frame 2 at the other end are respectively connected and fixed to the two ends of the diagonal tie rod 4 by bolts, and the two diagonal tie rods 4 on the left and right sides are arranged in a cross pattern (see Figure 2 ).

[0030] Through the above-described scheme, this utility model, by designing a universal end frame 2 and end cover plate 3, can support and fix both ends of the sleeve 1. Furthermore, the end frames 2 at the same end position can be stacked into a rectangular array, allowing the sleeves 2 to be arranged in a rectangular array. Simultaneously, stacking in both width and height directions reduces the floor space occupied, thereby lowering transportation costs. Specifically, the first waist hole 211 is used to lock adjacent end frames 2, while the second waist hole 221 and third waist hole 222 are used to fix the upper and lower ends of the sleeve 1 respectively and provide fine-tuning space, improving tolerance during assembly. The end cover plate 3 covering the lower end of the sleeve 1 prevents dust from entering the sleeve 1 during transportation. The diagonal tie rods 4 located on the left and right sides of the sleeve array 100 are cross-arranged and tighten the frame arrays 200 at both ends, providing tension and limiting in the length direction, ensuring the structural stability of the entire sleeve array 100, and improving safety during transportation.

[0031] The following are specific embodiments of the present invention.

[0032] The upper flange hole 11 and the lower flange hole 12 are both arranged at equal angles along the axis of the sleeve 1 to achieve uniform arrangement.

[0033] To ensure the overall strength of the transport equipment, the aforementioned side rods 21 and diagonal braces 4 are made of angle steel; the fixed rods 22 are made of channel steel and are integrally connected to the corresponding side rods 21 by welding or other means.

[0034] The two diagonally connected side rods 21 in the end frame 2 are integrally connected by welding or other means with a diagonal connecting rod 23, thereby improving the strength of the end frame 2.

[0035] In the aforementioned frame array 200, the bottom side bar 21 of the lowest end frame 2 is made of channel steel, while the remaining side bars 21 are made of angle steel, and the lower ends of the left and right side bars 21 are inserted into the channel steel. This increases the grounding area of ​​the end frame 2 by utilizing the width of the channel steel, making the overall structure formed by the sleeve array 100 and the frame arrays 200 at both ends more stable and less prone to shaking.

[0036] A shaft 32 protrudes from the center of the outer end face of the aforementioned end cover plate 3. The shaft 32 is arranged along the axial direction of the end cover plate 3 and is configured as a hollow structure. Therefore, the shaft 32 is designed to support and protect the conductive rod inside the sleeve.

[0037] One end of the aforementioned diagonal tie rod 4 is provided with a first circular hole 41, and the other end is provided with at least one fourth waist hole 42 spaced apart along the length of the diagonal tie rod 4. During assembly, the end with the first circular hole 41 can be fixed first, and then the diagonal tie rod 4 can be rotated around the first circular hole 41 as an axis until one of the fourth waist holes 42 can align with one of the first waist holes 211, and then locked. In this way, the assembly requirements of sleeve arrays 100 of different lengths and heights can be met, and the installation flexibility is higher.

[0038] Furthermore, the aforementioned fourth waist hole 42 is set along the length direction of the tie rod 4.

[0039] This utility model also includes side connecting plates 5 fixed to the side of the frame array 200. The upper and lower ends of the side connecting plates 5 are respectively connected and fixed to the first waist holes 211 of the two adjacent end frames 2. Specifically, the upper part of the outer side of the side connecting plate 5 is provided with a second round hole 51, and the lower part is provided with at least one fifth waist hole 52 arranged at intervals along the vertical direction; the inner side of the side connecting plate 5 is provided with a lifting hole 53. During assembly, bolts are used to simultaneously pass through the second round hole 51 and the first waist hole 211 of the upper end frame 2 to achieve locking, and bolts are used to simultaneously pass through the fifth waist hole 52 and the first waist hole 211 of the lower end frame 2 to achieve locking. The fifth waist hole 52 also provides space for adjusting the position of the bolts, improving the fault tolerance during assembly. After the entire array is assembled, a total of four side connecting plates 5 are configured, that is, one lifting hole 53 is provided on each side front and rear, which facilitates lifting the entire array and moving it to a vehicle. Thus, the sleeve 1 and the end frame 2 can be assembled one by one on the ground and then lifted, making the installation more difficult.

[0040] Furthermore, the aforementioned fifth waist hole 52 is arranged along the vertical direction.

[0041] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
