As shown in Figure 4, the bottom of the movable platform 501 passes through the workbench 3 and is fixedly installed with a guide rod 515. A vertical column 6 is rotatably installed in the middle of the lower surface of the workbench 3. A horizontal guide plate 7 is fixedly installed on the vertical column 6. The guide plate 7 is provided with an inclined groove 701 that cooperates with the guide rod 515; an outer gear ring 8 is fixedly installed on the outer circumferential surface of the guide plate 7, a driving motor 9 is fixedly installed on the base plate 1, and a driving gear 10 meshing with the outer gear ring 8 is fixedly installed on the output shaft of the driving motor 9.

After the switch base 13a is fixed, the driving gear 10 is driven to rotate by the driving motor 9, thereby driving the outer gear ring 8 and the guide plate 7 to rotate, and the inclined groove 701 on the guide plate 7 generates an interaction force with the guide rod 515, so that the guide rod 515 drives the panel adjustment mechanism 5 to move horizontally as a whole until the panel adjustment mechanism 5 reaches the predetermined working position, and then the panel 13b is manually placed at a position between each panel adjustment mechanism 5, and the bottom surface of the panel 13b is in contact with the upper surface of the push plate 507; in this state, the panel 13b is pressed downward, and the panel 13b drives the push plate 507, the guide sleeve 506, the lifting platform 502, the pressure plate 508, the pressure plate 509, the return spring 510 and the guide roller 511 to move downward as a whole, and the guide roller 511 drives the push plate 507 to move horizontally toward the buckle 13c under the guiding action of the guide block 514, and the push plate 507 is in contact with the buckle 13c and pushes the buckle 13c slightly. The push plate 507 is clamped between the switch base 13a and the panel 13b. In this state, the driving motor 9 drives the driving gear 10 to rotate in the opposite direction, thereby driving the outer gear ring 8 and the guide plate 7 to rotate in the opposite direction. The inclined groove 701 on the guide plate 7 and the guide rod 515 generate an interaction force, so that the guide rod 515 drives the panel adjustment mechanism 5 to move horizontally in the opposite direction as a whole, until the push plate 507 is separated from the switch base 13a and the panel 13b. After losing the thrust of the push plate 507, the buckle 13c fits with the inner wall of the switch base 13a during the resetting process, and finally continues to press the panel 13b downward until the bottom surface of the panel 13b fits with the top surface of the switch base 13a, and the buckle 13c is clamped into the corresponding position in the switch base 13a.

As shown in Figures 1 and 5, a synchronization mechanism 11 is installed between two adjacent panel adjustment mechanisms 5. The synchronization mechanism 11 includes a horizontal L-shaped sleeve 111. Horizontal sliding rods 112 are slidably installed at both ends of the L-shaped sleeve 111. The outer end of the sliding rod 112 is fixedly connected to the lifting platform 502. When the panel adjustment mechanism 5 moves horizontally, the sliding rod 112 retracts and contracts in the L-shaped sleeve 111 to ensure that the heights of the lifting platforms 502 in each of the two panel adjustment mechanisms 5 are consistent, thereby ensuring that the distribution switch panel is always in a horizontal state during the installation process.

As shown in Figures 2 and 7, a pressing mechanism 12 is installed on the base plate 1, and the pressing mechanism 12 includes a hydraulic cylinder 121 vertically fixedly installed on the base plate 1, and a horizontal bar 122 is fixedly installed on the top of the telescopic section of the hydraulic cylinder 121.

The inner diameter of the circular groove 126 and the limiting cylinder 127 are the same; balls 128 are evenly installed around the circular groove 126 on the bottom surface of the pressing block 125; a vertical fixed shaft 129 is fixedly installed on the upper surface of the horizontal bar 122, and a horizontal plate is sleeved on the fixed shaft 129 1210, the horizontal plate 1210 slides up and down along the fixed axis 129 and can rotate freely; the horizontal plate 1210 is vertically fixed with positioning rods 1211 equal to the number of the pressing block 125, the bottom surface of the positioning rod 1211 is a hemispherical surface, and the diameter of the positioning rod 1211 is the same as the inner diameter of the circular groove 126; a horizontal rod 1212 is fixedly installed on the fixed axis 129, and an L-shaped baffle 1213 is fixedly installed at the end of the horizontal rod 1212.

The hydraulic cylinder 121 drives the horizontal bar 122, the connecting frame 123, the horizontal frame 124 and the pressing block 125 to move downward. After the pressing block 125 is in contact with the top surface of the panel 13b, the rotation angle and height of the horizontal plate 1210 are adjusted so that the positioning rod 1211 extends into the limiting cylinder 127 and is inserted into the circular groove 126, the screw hole on the panel 13b and the screw hole on the switch base 13a in turn, thereby aligning the screw hole on the panel 13b and the screw hole on the switch base 13a, ensuring that the circular groove 126, the screw hole on the panel 13b and the screw hole on the switch base The axes of the screw holes on the seat 13a coincide with each other. The positioning rod 1211 is moved out of the limiting cylinder 127 by adjusting the rotation angle and height of the horizontal plate 1210, and the height of the horizontal plate 1210 and the positioning rod 1211 are limited by the baffle 1213; the panel 13b can be pushed downward by the pressing mechanism 12, and when the bottom surface of the panel 13b is in contact with the top surface of the switch base 13a, the screw 13d is inserted into the limiting cylinder 127, and the screw 13d is installed into the screw hole on the panel 13b and the screw hole on the switch base 13a by a screw gun.

Then, the panel 13b is manually placed between the panel adjustment mechanisms 5, and the bottom surface of the panel 13b is in contact with the upper surface of the push plate 507; in this state, the screw holes on the panel 13b and the screw holes on the switch base 13a are positioned by the positioning rod 1211; the panel 13b is pressed downward by the pressing mechanism 12, and during this process, the push plate 507 moves horizontally toward the buckle 13c and pushes the buckle 13c to bend slightly, so that the bottom end of the buckle 13c is located above the inner side of the switch base 13a; as the panel 13b continues to move downward, the buckle 13c finally extends into the switch base 13a , the push plate 507 is clamped between the switch base 13a and the panel 13b; in this state, the driving motor 9 drives the driving gear 10 to rotate in the opposite direction, and the guide rod 515 drives the panel adjustment mechanism 5 to move horizontally in the opposite direction as a whole, until the push plate 507 is separated from between the switch base 13a and the panel 13b, and the buckle 13c after losing the thrust of the push plate 507 fits with the inner wall of the switch base 13a during the resetting process, and continues to press the panel 13b downward through the pressing mechanism 12 until the bottom surface of the panel 13b fits with the top surface of the switch base 13a, and the buckle 13c is snapped into the corresponding position in the switch base 13a.
