[0013] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It should be noted that in the description of this utility model, the terms "inner", "outer", "upper", "lower", "both sides", "one end", "the other end", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0014] Please see Figures 1-4 This utility model provides a technical solution: a three-position disconnect switch housing displacement assembly trolley fixture, including a frame 1, a support frame 2, directional casters 3, and universal casters 4. Directional caster brackets 5 are provided on both sides of one end of the frame 1, and universal caster brackets 6 are provided on both sides of the other end of the frame 1. Each directional caster bracket 5 contains a directional caster 3, and each universal caster bracket 6 contains a universal caster 4. The universal casters 4 are connected to brakes 12 to ensure the stability of the displacement assembly trolley fixture when assembling or disassembling the three-position disconnect switch housing. The upper surface of the universal caster brackets 6 is connected to both ends of a trolley handle 13, allowing for easy pushing of the trolley fixture via the trolley handle 13. A support frame 2 is provided on the upper surface of the frame 1, and first diagonal braces 10 are provided on both sides of the support frame 2. 2. Two second diagonal braces 11 are provided at one end. The bottom of the first diagonal brace 10 and the second diagonal brace 11 are connected to the upper surface of the frame 1. The cooperation of the first diagonal brace 10 and the second diagonal brace 11 ensures the structural strength of the upright frame 2, thereby ensuring the stability of the worm gear reducer 7, and thus ensuring the overall stability of the three-position disconnect switch housing during transportation. The worm gear reducer 7 is provided on the upper part of the upright frame 2 near the directional caster 3. The input shaft of the worm gear reducer 7 is equipped with a handwheel 8. The output shaft of the worm gear reducer 7 is connected to the housing fixing rotating frame 9. The housing fixing rotating frame 9 is located directly above the frame 1. The housing fixing rotating frame 9 has several connecting holes 14 to be connected to the connecting seat of the three-position disconnect switch housing by bolts.

[0015] Usage and Principle: After lifting the three-position disconnect switch housing using hoisting equipment (such as a crane and electric hoist), move it above the frame 1. Align the connecting seat of the three-position disconnect switch housing with the housing fixing and rotating frame 9 of the assembly trolley tooling, and tighten the connection with bolts. Figure 5As shown. Subsequently, the housing of the three-position disconnect switch is moved to the assembly workshop via the directional casters 3 and swivel casters 4 of the positioning assembly trolley. According to the installation orientation, the handwheel 8 is turned, which drives the housing fixing rotation frame 9 to rotate through the worm gear reducer 7, thereby realizing the vertical, horizontal and inverted orientation adjustment of the housing of the three-position disconnect switch. With the help of hoisting equipment, the housing of the three-position disconnect switch is lifted, and the bolts connecting the housing fixing rotation frame 9 are removed, completing the transfer and repositioning of the housing of the three-position disconnect switch. This utility model has a reasonable structure. The frame 1 is equipped with directional casters 3 via directional caster 3 and universal casters 4 via universal caster frame 6. At the same time, a worm gear reducer 7 is installed via the upright frame 2. The input shaft of the worm gear reducer 7 is equipped with a handwheel 8, and the output shaft is equipped with a housing fixing and rotating frame 9. The housing fixing and rotating frame 9 can be connected to the housing of the three-position disconnect switch. The handwheel 8 and the worm gear reducer 7 can drive the housing fixing and rotating frame 9 to rotate, thereby driving the housing of the three-position disconnect switch to flip and change position. First, it has good mobility, which facilitates the transfer between workshops without the need to modify the workshop or add transfer and hoisting equipment, greatly reducing costs. Second, during transfer, it can be directly flipped and changed position according to the installation situation without the need for additional flipping equipment, improving flexibility and efficiency, and further reducing equipment investment costs.
