Four sliding boxes 33 are slidably sleeved on the outer walls of the guide rods 32. A safety belt 35 is provided inside the sliding box 33. The pulling end of the safety belt 35 passes through the outer wall of the sliding box 33 and is fixedly installed with a safety hook 36. A winding disk 34 is rotatably installed on the inner wall of the sliding box 33, and the safety belt 35 is arranged inside the winding disk 34. A torsion spring 37 is fixedly installed between the winding disk 34 and the sliding box 33; The mechanical and electrical installation personnel can move the moving seat 11, so as to move the entire device to the location where it is to be used. After the device is in place, the installation personnel can place the mechanical and electrical equipment to be installed on the support platform 23. Subsequently, the scissor lift 12 can be raised to lift the workbench 13, so that the mechanical and electrical equipment on the workbench 13 can be lifted to the installation location. At the same time, the installation personnel are lifted synchronously with the workbench 13.

[0026] As Figure 1 、 Figure 3 As shown in the figure, four groups of fine-tuning components distributed in a circular array are provided between the turntable 22 and the support platform 23. The fine-tuning component includes a slot 24 opened on the top surface of the turntable 22. A fine-tuning screw 25 is slidably installed on the inner wall of the slot 24. An adjusting nut 28 is rotatably installed on the top surface of the turntable 22, and the adjusting nut 28 is screwed with the fine-tuning screw 25.

A connecting rod 29 is fixedly installed on the bottom surface of the turntable 22. The bottom end of the connecting rod 29 passes through the fixed disk 21 and the workbench 13 in sequence and is fixedly installed with a driven bevel gear 210; When the staff installs the mechanical and electrical equipment, the angle of the mechanical and electrical equipment on the support platform 23 can be finely adjusted according to the actual situation of the installation. Specifically, the staff can rotate the adjusting nut 28. The adjusting nut 28 is rotatably connected with the turntable 22 and is screwed with the fine-tuning screw 25. Therefore, when the adjusting nut 28 rotates, it can drive the fine-tuning screw 25 to slide along the slot 24, and during the sliding process, the support platform 23 can be pushed through the connecting ball head 26 and the universal ball sleeve 27, so that a corner position of the support platform 23 is lifted, thereby realizing the angle fine-tuning of the mechanical and electrical equipment on the support platform 23 for precise installation.

[0027] As Figure 5 、Figure 7 As shown in the figure, a locking component is provided between the sliding box 33 and the guide rod 32. The locking component includes a chute 41 opened on the outer wall of the guide rod 32. A guiding frame 42 corresponding to the chute 41 is fixedly installed on the inner wall of the sliding box 33. A slider 43 is slidably installed at the bottom end of the guiding frame 42. Two first supporting springs 44 are symmetrically and fixedly installed between the top surface of the slider 43 and the sliding box 33. Openings 45 are opened on both side surfaces of the guiding frame 42. A pressing plate 46 is slidably installed on the inner wall of the opening 45. The positions of the pressing plate 46 and the slider 43 opposite to each other are both provided with corresponding inclined surfaces; When the sliding box 33 slides along the guide rod 32, the guiding frame 42 can slide in the chute 41. If an accidental fall occurs during the installation process of the staff, at this time, the safety rope and the safety belt 35 can pull the staff to prevent the staff from falling to the ground. At the same time, when the staff falls, the sliding box 33 can be pulled downward under the action of gravity. At this time, under the action of pressure, the guiding frame 42 can slide in the chute 41 and move relative to the slider 43 to compress the first supporting spring 44. When the guiding frame 42 and the slider 43 move relatively, the slider 43 can drive the pressing plate 46 under the action of the inclined surface, so that the pressing plate 46 slides out of the opening 45 and abuts against the inner wall of the chute 41, thereby realizing the limit locking of the sliding box 33 and avoiding secondary injuries caused by the sliding of the sliding box 33 when the staff falls.

[0028] As Figure 4 , Figure 6 shown in the figure, a lifting component is provided between one of the four sliding boxes 33 and the connecting plate 31. The lifting component includes a connecting gear ring 51 rotatably installed on the side surface of the sliding box 33. The end of the connecting gear ring 51 passes through the side surface of the sliding box 33 and is fixedly connected to the winding disc 34. A fixed rod 52 is fixedly installed on the side surface of the sliding box 33. A sliding ring 53 is slidably sleeved on the fixed rod 52. A second supporting spring 54 is fixedly installed between the sliding ring 53 and the side surface of the sliding box 33. A limit rack 55 meshing with the connecting gear ring 51 is fixedly installed on the bottom surface of the sliding ring 53. A fixing plate 56 is fixedly installed on the top surface of the connecting plate 31. A fixing frame 57 is fixedly installed at the top end of the fixing plate 56. The size of the fixing frame 57 is the same as that of the sliding ring 53. A driving gear 58 meshing with the connecting gear ring 51 is rotatably installed on the bottom surface of the connecting plate 31 through a mounting plate. A connecting bevel gear 59 is fixedly installed on the side surface of the driving gear 58; When the staff enters the workbench 13, they need to connect the safety rope on their body to the safety hook 36 at the end of the safety belt 35. And the length of the safety belt 35 extending out of the sliding box 33 can be adjusted according to the actual use situation. When adjusting, the staff can press the sliding ring 53 so that the sliding ring 53 slides along the fixed rod 52 and drives the limit rack 55 to separate from the connecting gear ring 51, thus releasing the limit on the winding disc 34. At this time, the safety hook 36 can be pulled. When the safety belt 35 is pulled out to an appropriate length, the staff can release the sliding ring 53. At this time, under the action of the second support spring 54, the limit rack 55 can be meshed with the connecting gear ring 51 again to realize the limit on the winding disc 34. When retracting the safety belt 35, the sliding ring 53 can be pressed again, the limit rack 55 is separated from the connecting gear ring 51, and under the action of the torsion spring 37, the winding disc 34 can rotate in reverse to store the safety belt 35; After adjusting the safety belt 35 and connecting it to the safety rope, during the installation operation, the staff can pull the sliding box 33 through the safety rope and the safety belt 35 so that the sliding box 33 slides along the guide rod 32, so that the sliding box 33 can move with the staff to avoid affecting the staff's operation.

[0029] As Figure 8 , Figure 9 As shown in the figure, a control component is arranged on the bottom surface of the workbench 13. The control component includes a fixed frame 61 fixedly installed on the bottom surface of the workbench 13. A transmission rod 62 is rotatably installed on the inner wall of the fixed frame 61. A set of bevel gears 63 is fixedly sleeved on the outer wall of the transmission rod 62. A servo motor 64 is fixedly installed on the bottom surface of the workbench 13. The output end of the servo motor 64 is fixedly installed with a driving bevel gear 65 meshed with the set of bevel gears 63. Linkage bevel gears 66 are fixedly installed at both ends of the transmission rod 62. The two linkage bevel gears 66 are respectively meshed with a connecting bevel gear 59 and a driven bevel gear 210. An electric push rod 67 is fixedly installed on the bottom surface of the workbench 13. The telescopic end of the electric push rod 67 is fixedly installed with a connecting ring 68, and the connecting ring 68 is rotatably sleeved on the outer wall of the transmission rod 62; Before installation, the support table 23 can be driven to rotate and adjust the installation position of the electromechanical equipment on the support table 23. When adjusting, the electric push rod 67 can be shortened. When the electric push rod 67 is shortened, it can drive the connecting ring 68 to move and pull the transmission rod 62, so that the transmission rod 62 slides along the fixed frame 61. The linkage bevel gear 66 at the end of the transmission rod 62 can be meshed with the driven bevel gear 210. At this time, when the servo motor 64 is started, it can drive the driving bevel gear 65 to rotate. The driving bevel gear 65 is meshed with the set of bevel gears 63, and then the transmission rod 62 can be driven, and the connecting rod 29, the turntable 22, the support table 23 and the electromechanical equipment can be driven to rotate through the linkage bevel gear 66 and the driven bevel gear 210 to realize the adjustment of the position of the electromechanical equipment; During the installation of electromechanical equipment, when the staff needs to transport other tools, etc. to the workbench 13 for use, one of the sliding boxes 33 can be moved along the guide rod 32 towards the position close to the connecting plate 31. If the safety belt 35 in this sliding box 33 is used by the staff, the staff can first disconnect the safety rope from the safety hook 36 and connect the safety rope to the guide rod 32 to ensure the safety of the staff. During the movement of the sliding box 33, the fixed frame 57 on the connecting plate 31 can first contact and squeeze the slip ring 53, thereby driving the limit rack 55 to separate from the connecting tooth ring 51 and releasing the limit on the winding disc 34. When the limit rack 55 is completely separated from the connecting tooth ring 51, the connecting tooth ring 51 can be synchronously engaged with the driving gear 58. At this time, the electric push rod 67 can be extended. When the electric push rod 67 extends, it can drive the transmission rod 62 to slide reversely along the fixed frame 61, so that the linkage bevel gear 66 at the other end thereof is engaged with the connecting bevel gear 59. At this time, the servo motor 64 can be turned on to drive the transmission rod 62 to rotate, and drive the driving gear 58 to rotate through the linkage bevel gear 66 and the connecting bevel gear 59. When the driving gear 58 rotates, it can drive the connecting tooth ring 51 and the winding disc 34, and the winding and unwinding of the safety belt 35 in the winding disc 34 can be controlled by controlling the forward and reverse rotation of the servo motor 64. Connect the lifting disc for placing tools to the safety hook 36, and the lifting of the tools can be realized, so that the staff can lift and take the tools for the second time, and the operation is more convenient.

[0030] For the technical solution provided by the present invention, during use, first, the electromechanical installer can move the moving seat 11, thereby moving the entire device to the location of use. After the device is in place, the installer can place the electromechanical equipment to be installed on the support table 23, and then raise the scissor lift 12 to lift the workbench 13, so that the electromechanical equipment on the workbench 13 can be lifted to the installation location. At the same time, the installer is lifted synchronously with the workbench 13. When the staff installs the electromechanical equipment, the angle of the electromechanical equipment on the support table 23 can be finely adjusted according to the actual situation of the installation. Specifically, the staff can rotate the adjusting nut 28. The adjusting nut 28 is rotatably connected to the turntable 22 and is screwed to the fine adjustment screw rod 25. Therefore, when the adjusting nut 28 rotates, it can drive the fine adjustment screw rod 25 to slide along the slot 24, and during the sliding process, the support table 23 can be pushed by the connecting ball head 26 and the universal ball sleeve 27, so that a corner position of the support table 23 is lifted, thereby realizing the fine adjustment of the angle of the electromechanical equipment on the support table 23 for accurate installation. Meanwhile, the support table 23 can be driven before installation to rotate and adjust the installation position of the electromechanical equipment on the support table 23. When adjusting, the electric push rod 67 can be shortened. When the electric push rod 67 is shortened, it can drive the connecting ring 68 to move and pull the transmission rod 62, causing the transmission rod 62 to slide along the fixed frame 61. The linkage bevel gear 66 at the end of the transmission rod 62 can engage with the driven bevel gear 210. At this time, turning on the servo motor 64 can drive the driving bevel gear 65 to rotate. The driving bevel gear 65 meshes with the sleeved bevel gear 63, and then the transmission rod 62 can be driven. Moreover, the connecting rod 29, the turntable 22, the support table 23 and the electromechanical equipment can be driven to rotate through the linkage bevel gear 66 and the driven bevel gear 210, realizing the adjustment of the position of the electromechanical equipment; When the staff enters the workbench 13, the safety rope on their body needs to be connected to the safety hook 36 at the end of the safety belt 35, and the length of the safety belt 35 extending out of the sliding box 33 can be adjusted according to the actual use situation. When adjusting, the staff can press the sliding ring 53 to make the sliding ring 53 slide along the fixed rod 52 and drive the limit rack 55 to separate from the connecting toothed ring 51, thus releasing the limit on the winding disc 34. At this time, the safety hook 36 can be pulled. When the safety belt 35 is pulled out to an appropriate length, the staff can release the sliding ring 53. At this time, under the action of the second support spring 54, the limit rack 55 can mesh with the connecting toothed ring 51 again, realizing the limit on the winding disc 34. When retracting the safety belt 35, the sliding ring 53 can be pressed again, and the limit rack 55 separates from the connecting toothed ring 51. Under the action of the torsion spring 37, the winding disc 34 can reverse to store the safety belt 35; After adjusting the safety belt 35 and connecting it to the safety rope, during the installation operation process, the staff can pull the sliding box 33 through the safety rope and the safety belt 35 to make the sliding box 33 slide along the guide rod 32, so that the sliding box 33 can move with the staff to avoid affecting the staff's operation. When the sliding box 33 slides along the guide rod 32, the guide frame 42 can slide in the chute 41. If the staff accidentally falls during the installation process, at this time, the safety rope and the safety belt 35 can pull the staff to prevent the staff from falling to the ground. At the same time, when the staff falls, under the action of gravity, the sliding box 33 can be pulled downward. At this time, under the action of pressure, the guide frame 42 can slide in the chute 41 and move relative to the slider 43 to compress the first support spring 44. When the guide frame 42 and the slider 43 move relative to each other, under the action of the inclined plane, the slider 43 can drive the abutting plate 46, making the abutting plate 46 slide out of the opening 45 and abut against the inner wall of the chute 41, thus realizing the limit locking of the sliding box 33 to avoid secondary injury caused by the sliding of the sliding box 33 when the staff falls; When the staff need to transport other tools to the workbench 13 for use during the installation of electromechanical equipment, one of the sliding boxes 33 can be moved along the guide rod 32 towards the position close to the connecting plate 31. When the safety belt 35 in this sliding box 33 is used by the staff, the staff can first disconnect the safety rope from the safety hook 36 and connect the safety rope to the guide rod 32 to ensure the safety of the staff. During the movement of the sliding box 33, the fixed frame 57 on the connecting plate 31 can first contact and squeeze the sliding ring 53, thereby driving the limit rack 55 to separate from the connecting gear ring 51 and releasing the limit on the winding disc 34. When the limit rack 55 is completely separated from the connecting gear ring 51, the connecting gear ring 51 can be synchronously engaged with the driving gear 58. At this time, the electric push rod 67 can be extended. When the electric push rod 67 extends, it can drive the transmission rod 62 to slide in the opposite direction along the fixed frame 61, so that the linkage bevel gear 66 at the other end thereof is engaged with the connecting bevel gear 59. At this time, the servo motor 64 can be turned on to drive the transmission rod 62 to rotate, and drive the driving gear 58 to rotate through the linkage bevel gear 66 and the connecting bevel gear 59. When the driving gear 58 rotates, it can drive the connecting gear ring 51 and the winding disc 34, and the winding and unwinding of the safety belt 35 in the winding disc 34 can be controlled by controlling the forward and reverse rotation of the servo motor 64. Connect the lifting disc for placing tools to the safety hook 36, and the lifting of the tools can be realized, so that the staff can lift and take the tools for the second time, and the operation is more convenient.
