[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] This embodiment proposes an auxiliary tool for the installation of electrical equipment, such as... Figures 1 to 5As shown, the tool includes a rectangular base 1 with a hollowed-out interior forming a rectangular clamping area 4. One side of the base 1 has a notch and a hinged rotating enclosure 3. The clamping area 4 is connected to the outside through the opening of the rotating enclosure 3, so that the base 1 can cover the electrical equipment. In specific applications, the rotating enclosure 3 is connected to the base 1 by a buckle. When the tool is not in use, the rotating enclosure 3 closes the base 1. When the tool is in use, the rotating enclosure 3 is opened first, and the tool is moved by the wheels 2 at the bottom of the base 1 to adjust the position of the tool according to the shape of the electrical equipment, so that the electrical equipment is exactly in the middle of the clamping area 4. Then the rotating enclosure 3 is closed.

[0023] The top of both sides of the base 1 is also fixed with a mounting bracket 5 in the vertical direction. Two clamping plates 9 are symmetrically distributed between the two mounting brackets 5. After the two clamping plates 9 move towards each other to clamp the electrical equipment, they move synchronously along the height direction of the mounting bracket 5 to lift the electrical equipment. The position of the electrical equipment has been adjusted in the above implementation scheme. At this time, after the electrical equipment is clamped by the two clamping plates 9, it is directly lifted to the target height by sliding upward along the mounting bracket 5.

[0024] In the above scheme, the entire electrical equipment is fixed entirely by the clamping force of the two clamping plates 9, and there is no support force at the bottom. This makes the lifting of the electrical equipment unstable and poses a certain safety risk (the electrical equipment may fall due to the insecure clamping). In view of this, this embodiment sets several support plates 14 inside the base 1. When the two clamping plates 9 clamp the electrical equipment and rise to a height above the support plates 14, all the support plates 14 rotate to the inside of the clamping area 4 and contact the bottom of the electrical equipment, thereby forming a support and protection for it. It should be noted that the support plates 14 do not apply an upward force to the electrical equipment, but play a protective role.

[0025] Specifically, regarding the vertical movement of the two clamping plates 9, in this embodiment, a guide rod 7 is fixed vertically in the middle of one of the mounting frames 5, and a threaded rod 6 is rotatably mounted vertically in the middle of the other mounting frame 5 (the threaded rod 6 is connected to the motor output end pre-embedded inside the base 1). A U-shaped lifting frame 8 is provided between the two mounting frames 5, with the notch of the U-shaped lifting frame 8 facing the notch of the base 1. Two hydraulic cylinders 10 are installed on the outer side of the U-shaped lifting frame 8 facing the mounting frame 5. The piston rods of the two hydraulic cylinders 10 pass through the U-shaped lifting frame 8 and are fixedly connected to the clamping plates 9. A slider 11 is provided between the two hydraulic cylinders 10, and the slider 11 is fixed to the back of the U-shaped lifting frame 8. One slider 11 is slidably sleeved on the outside of the guide rod 7, and the other slider 11 is threadedly sleeved on the threaded rod 6. The motor drives the threaded rod 6 to rotate, thereby driving the U-shaped lifting frame 8 to move vertically. The hydraulic cylinders 10 extend and drive the clamping plates 9 to move toward each other, ultimately clamping the electrical equipment.

[0026] Furthermore, in this embodiment, a telescopic rod 13 is provided at the bottom of the U-shaped lifting frame 8 near the clamping plate 9. The telescopic end of the telescopic rod 13 is rotatably connected to the bottom of the U-shaped lifting frame 8, and the fixed end is fixedly connected to a support plate 14 in a direction perpendicular to its axial direction. A receiving groove 12 with a matching shape is provided on the inner side of the base 1 at the position corresponding to the telescopic rod 13 and the support plate 14. The telescopic end of the telescopic rod 13 extends upward and passes through the top of the U-shaped lifting frame 8, and a knob rod 17 is fixed thereon. Two limiting plates 16 are also fixedly sleeved on the telescopic end of the telescopic rod 13. The two limiting plates 16 are respectively attached to the upper and lower sides of the U-shaped lifting frame 8. It can be understood that, under the limiting action of the two limiting plates 16, the telescopic end of the telescopic rod 13 is relative to the U-shaped lifting frame. 8 remains fixed in the vertical direction. The movement is of the fixed end of the telescopic rod 13. When the two clamping plates 9 hold the electrical equipment and move it upward, the movable end of the telescopic rod 13 and the U-shaped lifting frame 8 move upward synchronously. At this time, the fixed end of the telescopic rod 13 extends because the support plate 14 is stuck in the receiving groove 12. The telescopic rod 13 extends until the bottom of the electrical equipment moves to the same height as the support plate 14. At this time, the telescopic rod 13 reaches its maximum extension distance and the electrical equipment can no longer move upward. At this time, personnel need to drive the telescopic rod 13 to rotate 90° through the knob 17 so that the support plate 14 completely disengages from the receiving groove 12. The support plate 14 protects the bottom of the electrical equipment and the electrical equipment can be lifted upward smoothly.

[0027] In the above scheme, the support plate 14 and the telescopic rod 13 cooperate with each other. In order to make the support plate 14 fit perfectly against the bottom of the electrical equipment, this embodiment also has specific limitations on the height of the support plate 14 and the extension of the telescopic rod 13, as follows: the distance between the support plate 14 and the ground is D1, and the maximum extension length of the telescopic rod 13 is D2, where D1=D2.

[0028] In addition, a spring 15 is also sleeved on the telescopic end of the telescopic rod 13. The upper end of the spring 15 is connected to the limiting plate 16, and the lower end is connected to the fixed end of the telescopic rod 13. The spring 15 can buffer the extension and retraction of the telescopic rod 13.

[0029] In a preferred embodiment, the base 1 has two telescopic rods 13 located on the same side of the U-shaped lifting frame 8, and the two support plates 14 face each other.
