Description

Technical Field

[0001] This utility model relates to the technical field of porcelain insulators, specifically to porcelain insulators for rigid suspension crossarms. Background Technology

[0002] Rigid suspension crossarm porcelain insulators support positioning insulation devices used to isolate live conductors and support busbar devices and other supporting positioning devices. These non-conductive devices include channel steel bases, suspension channel steel, suspension columns, T-head bolts, busbar clamps, rigid center anchors and their clamps, and rigid suspension pin insulators.

[0003] During use, the insulator's porcelain components may crack due to the thermal expansion of the metal fittings and the mechanical stress caused by the non-vertical installation of the upper metal fittings. Furthermore, it is inconvenient to adjust the position and height during installation, resulting in relatively poor applicability. In addition, the two sides of the crossbeam are exposed structures, and there is a lack of protective structure for the insulators during use, which can lead to damage during use due to external traffic. Overall, its use is quite limited. Summary of the Invention

[0004] The purpose of this invention is to provide a rigid suspension crossarm porcelain insulator to solve the above-mentioned defects caused by the prior art.

[0005] A rigid suspension crossarm porcelain insulator includes a suspension base, a guide rail, and an outer sleeve base. A U-shaped instrument base is connected to the upper part of the suspension base via a bearing. A positioning mechanism is provided above the instrument base. The positioning mechanism engages and positions obstructed instruments and facilitates the installation of multiple sets of insulators. An adjustment mechanism is provided on the outer side of the outer sleeve base. The adjustment mechanism adjusts the installation height according to installation requirements, thereby flexibly adjusting the installation position of insulators of different sizes.

[0006] Preferably, the positioning mechanism includes an instrument base plate, a side baffle plate, a slot, a guide rail, and a slider sleeve. The bottom end of the instrument base plate is connected to a suspension seat. Slots are symmetrically opened on both sides of the instrument base plate. The side baffle plate is connected to the outer side of the slot. A guide rail is provided directly above the instrument base plate. Slider sleeves are provided at equal intervals directly above the guide rail.

[0007] Preferably, the guide rail is connected to the bottom end of the vertical guide rod via a slider sleeve that is connected at equal intervals directly above.

[0008] Preferably, the adjusting mechanism includes an outer sleeve, a longitudinal support, an outer positioning groove, a ceramic skirt, a fastening hole, and a vertical guide rod. The longitudinal support is welded to one side of the outer sleeve, and the bottom end of the longitudinal support has an outer positioning groove. The bottom end of the outer positioning groove is connected to the ceramic skirt. A guide rail is connected to the outer side of the outer sleeve, and the outer side of the vertical guide rod is connected through the inside of the outer sleeve. The bottom end of the vertical guide rod is connected to the inside of the outer sleeve.

[0009] Preferably, the longitudinal support is connected to the outside of the guide rail via a through-hole outer sleeve.

[0010] Preferably, the longitudinal support is connected to the top of the ceramic skirt through an outer positioning groove at the bottom.

[0011] Preferably, the bottom end of the suspension seat is provided with equally spaced through holes for threading.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Multiple sets of slider sleeves are installed on the outside of the guide rail by pulling. This allows for adjustment of the installation position of ceramic skirts of different diameters according to installation requirements. Pulling the slider sleeves to slide on the outside of the guide rail facilitates quick adjustment of the spacing between multiple sets of slider sleeves. Pulling the outer sleeve allows it to slide on the outside of the vertical guide rod, thereby adjusting the height of the longitudinal support to the corresponding height, which facilitates locking multiple sets of insulators.

[0014] 2. The bottom ends of the side shields on both sides are positioned by symmetrically opened slots. During use, the side shields protect the two sides of the ceramic skirt, thereby reducing the contamination of the ceramic skirt surface by dirt, and preventing hard objects on the sides from directly contacting the ceramic skirt and causing the surface of the ceramic skirt to break.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 4 As shown, the rigid suspension crossarm porcelain insulator includes a suspension seat 1, a guide rail 3, and an outer sleeve seat 8. A U-shaped instrument base plate 2 is connected to the upper part of the suspension seat 1 via a bearing. A positioning mechanism 4 is provided above the instrument base plate 2. The positioning mechanism 4 engages and positions the obstructed instrument and facilitates the installation of multiple sets of insulators. An adjustment mechanism 6 is provided on the outer side of the outer sleeve seat 8. The adjustment mechanism 6 adjusts the installation height according to the installation requirements, thereby flexibly adjusting the installation position of insulators of different sizes.

[0023] In this embodiment, the positioning mechanism 4 includes an instrument base plate 2, a side baffle plate 5, a slot 10, a guide rail 3, and a slider sleeve 7. The bottom end of the instrument base plate 2 is connected to a suspension seat 1. Slots 10 are symmetrically opened on both sides of the instrument base plate 2. The side baffle plate 5 is connected to the outer side of the slot 10. The guide rail 3 is arranged directly above the instrument base plate 2. Slide sleeves 7 are arranged at equal intervals directly above the guide rail 3.

[0024] In this embodiment, the guide rail 3 is connected to the bottom end of the vertical guide rod 15 through the slider sleeve 7 connected at equal intervals directly above. The vertical guide rod 15 slides inside the slider sleeve 7, which facilitates the adjustment of the installation position of the vertical guide rod 15.

[0025] In this embodiment, the adjusting mechanism 6 includes an outer sleeve 8, a longitudinal support 9, an outer positioning groove 11, a ceramic skirt 12, a fastening hole 13, and a vertical guide rod 15. The longitudinal support 9 is welded to one side of the outer sleeve 8. The bottom end of the longitudinal support 9 is provided with an outer positioning groove 11. The bottom end of the outer positioning groove 11 is connected to the ceramic skirt 12. The outer side of the outer sleeve 8 is connected to a guide rail 3. The outer side of the vertical guide rod 15 is connected through the inside of the outer sleeve 8. The bottom end of the vertical guide rod 15 is connected to the inside of the outer sleeve 8. The metal rod is connected through the outer positioning groove 11.

[0026] In this embodiment, the longitudinal support 9 is connected to the outer side of the guide rail 3 through the outer sleeve 8 that is connected through the bottom end. The guide rail 3 connects to the outer side of the outer sleeve 8 and locks multiple sets of outer sleeves 8.

[0027] In this embodiment, the longitudinal support 9 is connected to the top of the ceramic skirt 12 through the outer positioning groove 11 at the bottom, and the threaded rod at the top of the ceramic skirt 12 is locked through the longitudinal support 9.

[0028] In this embodiment, the bottom end of the suspension seat 1 is provided with equally spaced wire holes 14, through which the wire is connected to the power cord.

[0029] In practical applications, this type of rigid suspension crossarm porcelain insulator includes the following tasks:

[0030] Step 1: During use, first, the bottom end of the suspension seat 1 is inserted through the positioning hole and then attached to the frame. The bottom end of the suspension seat 1 and the instrument base plate 2 are locked together with bolts. The operator then inserts the bottom end of the side baffle 5 into the outside of the slot 10 and locks the slot 10 and the bottom end of the side baffle 5 together with bolts. The side baffle 5 and the ceramic skirt 12 are blocked on both sides to prevent the ceramic skirt 12 from colliding with other hard objects.

[0031] Step 2: The operator then installs the slider sleeve 7 on the outside of the guide rail 3. According to the installation requirements, the installation position of the ceramic skirts 12 of different diameters is adjusted. The slider sleeve 7 is pulled to slide on the outside of the guide rail 3. After the spacing of multiple sets of slider sleeves 7 is adjusted, the bolts are inserted into the fastening holes 13 to fasten the slider sleeve 7 to the outside of the guide rail 3.

[0032] Step 3: The operator can pull the outer sleeve 8 according to the length of the ceramic skirt 12, so that the outer sleeve 8 slides on the outside of the vertical guide rod 15, thereby adjusting the height of the longitudinal support 9 to the corresponding height. Then, the outer sleeve 8 on one side of the longitudinal support 9 and the two sides of the vertical guide rod 15 are locked with fasteners to complete the height locking of the longitudinal support 9.

[0033] Step 4: The operator connects the metal rod that runs through the inside of the ceramic skirt 12 to the bottom of the outer positioning groove 11, then tightens the top of the metal rod with a nut, and then inserts the wire into the wire hole 14. The wire should be tied at a certain angle to the axis of the porcelain insulator to ensure that the wire is tightly fixed to the insulator and does not easily slip or loosen. The sides of the ceramic skirt 12 are shielded by the side shielding plates 5 set on both sides.

[0034] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
