There are no overhead power bridges or distribution devices in the workshop, so it is impossible to draw power from the air; there are no distribution facilities on the ground next to the production station, so it is impossible to draw power nearby. Power can only be drawn from the distribution box on the wall column using a wiring board or a cable drag, and various power tools are connected to the wiring board or cable drag; the power load of product debugging at the assembly station is large, and the temporary wiring board or cable drag cannot meet the power requirements. It is necessary to temporarily use cables to connect the power distribution box on the wall column to draw power, and then connect the product; the above two power-drawing methods use yellow plastic tripods to support the cables to prevent the cables from falling to the ground; the wiring board or cable drag has a variety of models and specifications, and the power load limit is difficult to guarantee; when debugging products, it is necessary to apply for professional personnel from the equipment safety and technology department to connect or remove the wires. The above-mentioned electricity use has certain safety hazards, and it is easy to cause confusion of cables at the assembly site, which has different degrees of impact on construction.

DETAILED DESCRIPTION

[0029] The utility model is further described below in conjunction with the accompanying drawings.

[0030] like Figure 1 , Figure 2 As shown, the utility model is a foldable wiring rack device, including a fixed support 1, a pin shaft 2, a support arm 3, a rotating fixed shaft 4, a thrust ball bearing 5, an expansion arm 6, an extension arm 7, a washer 8, a cotter pin 9, and a nut 10. The fixed seat 1 (such as Fig.13 As shown) is fixed to the plant column by expansion screws, the support arm 3 is hinged and fixed to the fixed support 1 by the pin 2, and the support arm 3 can rotate around the pin 2 (as shown) Fig.14 The support arm 3 is mainly used to support the wiring rack. Fig.10 As shown, the support arm 3 of the utility model can adopt a triangular truss structure, which has high strength and stability and can effectively ensure the support of the wiring rack.

[0031] like Figure 3 , Figure 2As shown, the deployment arm 6 of the utility model and the support arm 3 are connected by a rotating fixed shaft 4 (such as Fig. 9 As shown in the figure, two thrust ball bearings 5 ​​are hinged, and then fixed by washers 8, cotter pins 9, and nuts 10. The deployment arm 6 can rotate around the rotation fixed axis 4, and the rotation range is 0 to 360 degrees. The two stacked thrust ball bearings 5 ​​of the utility model can not only ensure that the deployment arm 6 can rotate flexibly around the support arm 3, but also effectively bear the deadweight load of the entire deployment mechanism. The deployment arm 6 mainly extends the wiring rack, and plays an external expansion and extension role.

[0032] like Fig.11 As shown, the deployment arm 6 of the present invention includes a truss 61 and a fixing flange 62, and the fixing flange 62 is arranged at the front of the truss 61. The fixing flange 62 has a certain number of circular holes evenly distributed in the circumferential direction, and the fixed part of the rotating disk 71 is fixed on the fixing flange 62 through the circular holes of the fixing flange 62.

[0033] like Fig.12 As shown, the extension arm 7 includes a rotating disk 71, a tube 72, and a terminal box 73. The terminal box 73 can be provided with a switch socket according to actual conditions. The cable connected to the switch socket is connected to the power line or air switch on the column of the plant through the tube 72, the truss 61, and the support arm 3. The rotating disk 71 includes a fixed part and a rotating part, and the rotating part can rotate 360° relative to the fixed part. The rotating part of the rotating disk 71 is connected to the tube 72. The cable is preferably arranged in the tube 72. A 380V socket 74, a 220V socket 75, a warning light 76, etc. can be arranged in the terminal box 73. The terminal box 73 is used for the integrated assembly of the socket and the warning light. The 380V socket 74 and the 220V socket 75 are used for power distribution output, which can meet different debugging and test voltage requirements. The warning light 76 is used to intuitively display whether there is electricity.

[0034] like Figures 4 to 7 As shown, the wiring rack device of the utility model can meet the power requirements of different working angles. The truss 61 of the utility model is preferably the same length as the support arm 3, so that after the equipment is operated, the extension arm 7 can be exactly located on the column of the factory building. Fig.15 , Fig.16 , Fig.17 As shown, the utility model wiring rack device has a span of about 5 meters when fully unfolded, and an installation height of more than 4.5 meters, which is greater than the equipment passage height requirement of 4.2 meters. It also has 220V and 380V voltage sockets, and the distribution box is 2 meters above the ground and is equipped with a warning light device. A special cable with a length of 1.2 meters is made, and the connector meets the requirements for assembly and debugging of various types of equipment.

[0035] The implementation method of the utility model is: firstly according to Figures 9 to 14 Produce and process the corresponding parts as shown; then follow Figure 1 , Figure 2, assemble and splice, first install the fixed support 1 on the plant column at a height of more than 4.5 meters from the ground, and fix it with expansion screws to ensure that it is firmly fixed, then hoist and install the support arm 3, hinge the support arm 3 on the fixed support 1 through the pin 2, and ensure that the support arm 3 can flexibly rotate around the pin 2, and then hinge the expansion arm 6 with the support arm 3 through the rotating fixed shaft 4 and two thrust ball bearings 5, and then fix it with washers 8, cotter pins 9, and nuts 10, which can ensure that the expansion arm 6 can flexibly rotate around the rotating fixed shaft 4 and be reliably fixed, and finally connect the extension arm 7 to the expansion arm 6, and fix it with a pin to ensure reliable connection; after the wiring rack is assembled, lay and interconnect the cables, and connect the required cables according to Fig.17 The cable rack is laid out in a fully unfolded form. The cables are wrapped with protective sleeves and tied to the cable rack with cable ties. Sufficient turning length is left at the hinges between the arms to ensure that the cable rack cannot be fully unfolded during the unfolding process. During the folding process, the bending radius is too small, resulting in cable extrusion and damage. Finally, follow the Fig.17 , Figure 8 , debug the wiring rack, observe whether the fully expanded and retracted states are reliable, then turn on the power, observe whether the indicator light 56 ​​is on, and insert the debugging and testing cables into the 380V socket 74 and the 220V socket 75 respectively to check whether the power demand is met. The device of the utility model can supply power to a large three-dimensional space in front of the factory column through the rotation combination of the support arm 3, the expansion arm 6, and the extension arm 7, ensuring that power can be obtained safely for the assembly, installation or debugging of large products, and can meet the connection requirements of power lines in different parts of the vehicle.
