Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Reference Figure 1-2 As shown, this utility model provides a device for installing and lifting an electrical cabinet in a passenger compartment, including a mobile platform for movement, a lifting component fixedly connected to the mobile platform, the lifting component for lifting a fork assembly, and a control component 40 electrically connected to the lifting component and controlling the lifting of the fork assembly.

[0020] The mobile platform includes a first mobile frame 11, one end of which is connected to a mobile wheel assembly 14. The mobile wheel assembly 14 includes casters for moving and lifting electrical cabinet devices in the passenger compartment. The other end of the first mobile frame 11 is fixedly connected to a third mobile frame 13. The third mobile frame 13 is connected to two mobile wheel assemblies 14. One end of the second mobile frame 12 is fixedly connected to the third mobile frame 13. The other end of the second mobile frame 12 is connected to the mobile wheel assembly 14.

[0021] A base plate 32 is mounted on the third movable frame 13. A lifting frame 31 is fixedly connected to the base plate 32. Two sets of guide rails 33 are arranged parallel to each other in the vertical direction on the lifting frame 31. Two sliders 34 are slidably fitted on each guide rail 33. An electric push rod 36 is vertically connected to the base plate 32. The other end of the electric push rod 36 is connected to a connecting plate 35. That is, the top of the electric push rod 36 is connected to the connecting plate 35. The extension and retraction of the electric push rod 36 causes the connecting plate 35 to rise and fall in the vertical direction. A handle 37 is provided on the top of the lifting frame 31. Holding the handle 37 allows for convenient movement, installation, and lifting of the electrical cabinet along the site.

[0022] The lifting moving plate 21 is fixedly connected to the connecting plate 35 and the slider 34 respectively, and moves on the guide rail 33 along with the slider 34. The fork 22 is fixedly connected to the lifting moving plate 21. The height of the fork 22 can be inserted to the bottom of the electrical cabinet. The contact surface between the fork 22 and the electrical cabinet is the upper surface. The upper surface of the fork 22 is designed according to the shape of the bottom of the electrical cabinet to ensure stable and reliable lifting and transportation. Two limit bars 23 are provided on the fork 22 to limit the forward and backward movement of the electrical cabinet. Six positioning holes 24 are provided on the side of the fork 22. A positioning shaft 25 is provided to rotate with the positioning holes 24. Two positioning protrusions 26 are provided at the end of the positioning shaft 25. The positioning protrusions 26 penetrate into the hole of the electrical cabinet base to lock the hole wall of the electrical cabinet base and fix the electrical cabinet to prevent the electrical cabinet from tipping over and falling.

[0023] A control component 40 is fixedly connected to the side of the lifting frame 31 opposite to the lifting assembly. The control component 40 is an electrical cabinet. The control component 40 is electrically connected to the electric push rod 36. The electrical cabinet is equipped with a power supply, which supplies power to the control component 40 and the electric push rod 36. A control button 41 is provided on the control component 40. The control button 41 controls the electric push rod 36 to realize the lifting of the lifting assembly.

[0024] Workflow:

[0025] The operator moves the device for installing and lifting the electrical cabinet, inserts the forks 22 into the bottom of the electrical cabinet, operates the control button 41 on the control component 40 to raise the forks 22 until the limit stop 23 locks the electrical cabinet, and rotates and adjusts the positioning shaft 25 so that the positioning protrusion 26 locks into the hole wall of the electrical cabinet base. Operating the control button 41 raises the electric push rod 36, and the connecting plate 35, through the lifting moving plate 21, drives the forks 22 to lift the electrical cabinet. The device for moving the electrical cabinet transports the electrical cabinet to the installation position. Operating the control button 41 lowers the electrical cabinet, and the operator adjusts the cabinet to the appropriate angle and position for assembly. The operator positions the electrical cabinet mounting holes and the vehicle body studs / mounting seats, and then rotates the positioning shaft 25 to disengage the electrical cabinet from the locking state.
