In summary, when the manhole door is assembled and disassembled, since the manhole door is arranged at the bottom of the vertical high-voltage equipment, the installation tool can be integrally moved to the position right below the equipment through the universal wheels 302a in the supporting assembly 300;

when the rotary table 104c is rotated, the overall height of the mounting plate 200 is increased, the mounting plate 200 is fixed with the manhole door through a second through hole K2 on the mounting plate 200 and a bolt is matched, then the rotary table 101a-2 and the rotary table 104c are continuously rotated, the mounting plate 200 jacks up the manhole door, the manhole door enters into high-pressure equipment, and meanwhile, a bottom mounting channel of the high-pressure equipment is separated from the manhole door, wherein when the rotary table 104c is rotated, a reverse thread column 104b and a positive thread column 104a of the outer wall of the bidirectional screw 104 are respectively in threaded fit with the first screw 103a and the second screw 103b, so that the mounting plate 200 rotates by taking a connection point of the fixing plate 201a and the first connecting rod 201 as a rotation point;

next, the entire disassembly and assembly tool is rotated by an angle of approximately 90 degrees, and the rotating knob 101a-2 and the turntable 104c are rotated in opposite directions simultaneously to lower the mounting plate 200 for removal from the high-voltage apparatus.

Finally, when the manhole door is installed, the rotating handle 101a-2 and the rotating disc 104c are required to be synchronously rotated in the same way, so that the installation plate 200 is lifted, the manhole door is sent into the high-voltage equipment, the whole installation tool is reversely rotated, the rotating disc 104c is independently rotated, and the installation plate 200 is restored to a horizontal state, namely, the installation of the manhole door and the high-voltage tool is completed.

The manhole door and the through hole at the bottom of the high-voltage equipment are self-fastened through the weight of the manhole door.

Example 2

Referring to fig. 3, the second embodiment of the present invention is based on the previous embodiment, except that, in order to avoid the deviation of the position of the whole equipment caused by the false slip of the universal wheel 302a during the lifting of the mounting plate 200, even the potential risk caused by the collision of the manhole door with the inner wall of the high-voltage equipment, the universal wheel 302a will be separated from the ground contact when the mounting plate 200 is lifted.

Specifically, the fixed frame 301 is externally provided with a third through hole K3 in a penetrating manner, the inner wall of the third through hole K3 is connected with the first rotating rod 302, the vertical cylinder 100 is externally provided with a fourth through hole K4, a sliding groove is arranged in the fourth through hole K4, the sliding groove is externally provided with a sliding plate 303 in a sliding manner, the sliding plate 303 is externally connected with the lifting rod 100a through the fourth through hole K4, the sliding plate 303 is externally hinged with a second rotating rod 303a, one end of the second rotating rod 303a is movably connected with the first rotating rod 302 through the third through hole K3, a supporting leg 304 is arranged on the outer matrix of the vertical cylinder 100, and the fixed frame 301 is externally provided with a collision frame 301a.

The abutting frame 301a is similar to a 7-shaped form, and when the first rotating rod 302 is in a vertical state, the abutting frame 301a can block the first rotating rod 302 from rotating continuously.

In summary, when the lifting rod 100a moves vertically upwards, the lifting rod 100a drives the sliding plate 303 to slide along the sliding groove in the fourth through hole 304, and the displacement of the sliding plate 303 causes the first rotating rod 302 to rotate through the second rotating rod 303a to lift the universal wheel 302a, at this time, the universal wheel 302a is separated from contact with the ground, so that the supporting leg 304 supports the whole tool, and in order to avoid the action, the whole tool is severely rocked, the bottom end surface of the supporting leg 304 is slightly higher than the bottom end surface of the universal wheel 302 a;

when the lifting rod 100a moves vertically downwards, the second rotating rod 303a will make the first rotating rod 302 return to the vertical state, and limit the vertical state by the abutting frame 301a, so as to avoid excessive rotation and ensure that the universal wheel 302a can contact with the ground.

Example 3

Referring to fig. 3-5, a third embodiment of the present invention is based on the previous embodiment, except that the rotatable assembly 305 is configured to assist in rotating the entire tool when the tool is to be rotated, thereby preventing over-rotation.

Specifically, the bottom of the vertical tube 100 is provided with a rotating assembly 305, the rotating assembly 305 includes a top plate 305a and a bottom plate 305b, a fifth through hole K5 is provided at the bottom of the top plate 305a, an L-shaped chute 305a-1 is provided on the inner wall of the fifth through hole K5, a connecting column 305b-1 is provided at the top of the bottom plate 305b, a connecting block 305b-20 slidably engaged with the L-shaped chute 305a-1 is provided outside the connecting column 305b-1, and an elastic member 305a-2 is provided in the fifth through hole K5.

The elastic member 305a-2 is a compression spring, and a stopper is disposed in the L-shaped chute 305a-1 to prevent the bottom plate 305b from coming out of contact with the top plate 305 a.

In summary, when the universal wheel 302a is out of contact with the ground, the bottom plate 305b will contact with the ground and force the connection block 305b-2 to slide in the L-shaped chute 305a-1, and the elastic member 305a-2 will give a certain buffer until the connection block 305b-2 will slide to the vertical end of the L-shaped chute 305a-1, the supporting leg 304 contacts with the ground, and then the tool is rotated, so that the connection block 305b-2 rotates along the L-shaped chute 305a-1, and the rotation angle of the L-shaped chute 305a-1 will be limited due to its own structural feature, so as to avoid the manhole door from being disassembled or assembled due to excessive rotation.
