The first supporting rod a1, the second supporting rod a2, the third supporting rod a3 and the fourth supporting rod a4 are vertically supported on the ground, and the lengths of the first supporting rod a1, the second supporting rod a2, the third supporting rod a3 and the fourth supporting rod a4 are all equal.
A left-right contraction mechanism is arranged between the first supporting rod a1 and the second supporting rod a 2. A left-right contraction mechanism is also arranged between the third supporting rod a3 and the fourth supporting rod a 4. The two left and right contraction mechanisms are symmetrical about the center of the central axis of the rectangular array, the connection relationship between the left and right contraction mechanisms between the first supporting rod a1 and the second supporting rod a2 and the first supporting rod a1 is equivalent to the connection relationship between the left and right contraction mechanisms between the third supporting rod a3 and the fourth supporting rod a4 and the third supporting rod a3, and the connection relationship between the left and right contraction mechanisms between the first supporting rod a1 and the second supporting rod a2 and the second supporting rod a2 is equivalent to the connection relationship between the left and right contraction mechanisms between the third supporting rod a3 and the fourth supporting rod a4 and the fourth supporting rod a 4. Therefore, only the left-right contracting mechanism between the first supporting rod a1 and the second supporting rod a2 will be described in detail in this embodiment.
The left-right contraction mechanism comprises a left-right contraction screw rod b1, a left-right contraction nut b2, a first left-right connecting rod b3, a second left-right connecting rod b4, a third left-right connecting rod b5, a fourth left-right connecting rod b6, a first left-right shaft sleeve b7 and a second left-right shaft sleeve b 8.
The left and right shrinkage screw rods b1 are vertically arranged, the left and right shrinkage screw rods b1 are positioned between the first supporting rod a1 and the second supporting rod a2, and the left and right shrinkage screw rods b1, the first supporting rod a1 and the second supporting rod a2 are positioned in the same vertical plane. The upper end of the left and right shrinkage screw rod b1 is provided with a first motor, and a left and right shrinkage nut b2 is in threaded connection with the left and right shrinkage screw rod b 1. The first left and right axle sleeves b7 are slidably connected to the first support rod a1, and the second left and right axle sleeves b8 are slidably connected to the second support rod a 2.
The first left and right link b3, the second left and right link b4, the third left and right link b5, and the fourth left and right link b6 are all equal in length. The upper end of the first left and right link b3 is rotatably mounted on the upper end of the first support rod a1, the lower end of the first left and right link b3 is rotatably mounted on the left and right contraction nut b2, the lower end of the second left and right link b4 is rotatably mounted on the first left and right bushing b7, and the upper end of the second left and right link b4 is rotatably mounted on the first motor, so that the upper end of the second left and right link b4 is rotatably mounted on the upper end of the left and right contraction screw b 1. The midpoint of the first left and right link b3 and the midpoint of the second left and right link b4 are pivotally connected to ensure that the first support bar a1 is always parallel to the left and right constrictor screws b 1.

The lower ends of the first and fourth left and right links b3 and b6 limit the left and right draw nut b2 to restrain the rotation of the left and right draw nut b 2. The first motor drives the left and right retracting screw b1 to rotate, and then the left and right retracting nuts b2 move on the left and right retracting screw b1 in the vertical direction. The geometric relationship shows that the upper ends of the first motor, the first supporting rod a1 and the second supporting rod a2 are always at the same vertical height. The left and right contraction nuts b2 moving in the vertical direction can drive the lower end of the first left and right link b3 and the lower end of the fourth left and right link b6 to move up and down, so that the first left and right link b3 and the second left and right link b4 are driven to rotate relatively, the third left and right link b5 and the fourth left and right link b6 rotate relatively, meanwhile, the first left and right shaft sleeve b7 slides on the first support rod a1, the second left and right shaft sleeve b8 slides on the second support rod a2, and the horizontal left and right spacing between the first support rod a1 and the second support rod a2 can be changed without disassembling the first left and right link b3, the second left and right link b4, the third left and right link b5 and the fourth left and right link b 6.
A front-back contraction mechanism is arranged between the second supporting rod a2 and the third supporting rod a3, and a front-back contraction mechanism is also arranged between the first supporting rod a1 and the fourth supporting rod a 4. Similarly, the two front-rear retraction mechanisms are symmetrical about the center axis of the rectangular array, the connection relationship between the front-rear retraction mechanism between the second support bar a2 and the third support bar a3 and the second support bar a2 is equivalent to the connection relationship between the front-rear retraction mechanism between the first support bar a1 and the fourth support bar a4 and the fourth support bar a4, and the connection relationship between the front-rear retraction mechanism between the second support bar a2 and the third support bar a3 and the third support bar a3 is equivalent to the connection relationship between the front-rear retraction mechanism between the first support bar a1 and the fourth support bar a4 and the first support bar a 1. In this embodiment, only the front and rear retracting mechanism between the second support bar a2 and the third support bar a3 will be described in detail.
The front and back contraction mechanism comprises a front and back contraction screw rod c1, a front and back contraction nut c2, a first front and back connecting rod c3, a second front and back connecting rod c4, a third front and back connecting rod c5, a fourth front and back connecting rod c6, a first front and back shaft sleeve c7 and a second front and back shaft sleeve c 8. The first front-to-rear link c3, the second front-to-rear link c4, the third front-to-rear link c5, and the fourth front-to-rear link c6 are all equal in length.
The front and rear shrinkage screw rod c1 is vertically arranged between the second support rod a2 and the third support rod a3, and the front and rear shrinkage screw rod c1, the second support rod a2 and the third support rod a3 are also in the same vertical plane. The upper end of the front and rear shrinkage screw rod c1 is provided with a second motor, and a front and rear shrinkage nut c2 is in threaded connection with the front and rear shrinkage screw rod c 1. The first front and rear axle sleeves c7 are slidably connected to the second support rod a2, and the second front and rear axle sleeves c8 are slidably connected to the third support rod a 3. The upper end of the first front-rear link c3 is rotatably mounted on the upper end of the second support bar a2, and the lower end of the first front-rear link c3 is rotatably mounted on the front-rear contraction nut c 2. The lower end of the second front-rear link c4 is rotatably mounted on the first front-rear bushing c7, and the upper end of the second front-rear link c4 is rotatably mounted on the second motor, so that the upper end of the second front-rear link c4 is rotatably mounted on the upper end of the front-rear contraction screw c 1. The midpoint of the first front-to-rear link c3 and the midpoint of the second front-to-rear link c4 are pivotally connected. The upper end of the third front-rear link c5 is rotatably mounted on the second motor, so that the upper end of the third front-rear link c5 is rotatably mounted on the upper end of the front-rear pinch screw rod c1, and the lower end of the third front-rear link c5 is rotatably mounted on the second front-rear bushing c 8. The lower end of the fourth front-rear link c6 is rotatably mounted on the front-rear contraction nut c2, and the upper end of the fourth front-rear link c6 is rotatably mounted on the upper end of the third support rod a 3. The midpoint of the third front-to-rear link c5 and the midpoint of the fourth front-to-rear link c6 are pivotally connected.
Similar to the function of the left-right contraction mechanism, the second motor drives the front-rear contraction screw c1 to rotate, thereby controlling the front-rear contraction nut c2 to move up and down to control the change of the horizontal distance between the second support rod a2 and the third support rod a3 in the front-rear direction.
Taking the second support bar a2 as an example, the reduced distance between the first support bar a1 and the second support bar a2 requires the second left and right bushings b8 to slide downward on the second support bar a2, and the reduced distance between the second support bar a2 and the third support bar a3 requires the first front and rear bushings c7 to slide downward on the second support bar a 2. When the rectangular service room for electrical power rush repair in this embodiment is fully deployed, the distance between the first support bar a1 and the second support bar a2 is smaller than the distance between the second support bar a2 and the third support bar a 3.
Therefore, the first front and rear axle sleeve c7 of the second supporting rod a2 needs to have a larger downward distance than the second left and right axle sleeve b8, so that the first supporting rod a1 and the second supporting rod a2 are folded, and the second supporting rod a2 and the third supporting rod a3 are folded at the same time. On the second support bar a2, a second left and right bushing b8 is located above the first front and rear bushing c 7. Similarly, on the first support bar a1, the first left and right bushings b7 are located above the second front and rear bushings c 8; on the third supporting rod a3, the first left and right axle sleeves b7 are positioned above the second front and rear axle sleeves c 8; on the fourth support bar a4, the second left and right bushings b8 are located above the first front and rear bushings c 7.
When the rectangular overhaul room for power emergency repair is completely unfolded, a first left and right shaft sleeve b7 and a second front and rear shaft sleeve c8 on a first supporting rod a1 are closed, a first left and right shaft sleeve b7 and a second front and rear shaft sleeve c8 on a third supporting rod a3 are closed, a first front and rear shaft sleeve c7 and a second left and right shaft sleeve b8 on a second supporting rod a2 are closed, and a first front and rear shaft sleeve c7 and a second left and right shaft sleeve b8 on a fourth supporting rod a4 are closed. When the rectangular overhaul room for electric power rush repair is contracted, the second supporting rod a2 and the third supporting rod a3 are drawn close in the front-rear direction, the first supporting rod a1 and the fourth supporting rod a4 are drawn close in the front-rear direction, the first front-rear shaft sleeve c7 and the second front-rear shaft sleeve c8 slide downwards in advance, the first supporting rod a1 and the second supporting rod a2 are drawn close in the left-right direction, the third supporting rod a3 and the fourth supporting rod a4 are drawn close in the left-right direction, the first left-right shaft sleeve b7 and the second left-right shaft sleeve b8 slide downwards, and interference of the first left-right shaft sleeve b7 and the second front-rear shaft sleeve c8 and interference of the second left-right shaft sleeve b8 and the first front-rear shaft sleeve c 7. When fully deployed, the first left and right bushings b7 and the second front and rear bushings c8 are vertically spaced apart, and the second left and right bushings b8 and the first front and rear bushings c7 are vertically spaced apart. When the rectangular overhaul room for electric power emergency repair is unfolded again, the first supporting rod a1 and the second supporting rod a2 are unfolded in the left-right direction, the third supporting rod a3 and the fourth supporting rod a4 are unfolded in the left-right direction, the first left shaft sleeve b7 and the second left shaft sleeve b8 ascend firstly, then the second supporting rod a2 and the third supporting rod a3 are unfolded in the front-back direction, the first supporting rod a1 and the fourth supporting rod a4 are unfolded in the front-back direction, and the first front shaft sleeve c7 and the second front shaft sleeve c8 ascend again.
The roof of the rectangular overhaul house for power emergency repair needs to be provided with a ceiling, and the upper end of the first supporting rod a1, the upper end of the second supporting rod a2, the upper end of the third supporting rod a3 and the upper end of the fourth supporting rod a4 are fixed with the edge of the ceiling. The center of the rectangular array is provided with a guide rod e1, and the upper end of the guide rod e1 jacks up the middle of the ceiling.
The rectangular overhaul room for the power line emergency repair further comprises two first front and rear swing rods d1, two first left and right swing rods d2, two second front and rear swing rods d3 and two second left and right swing rods d 4. The guide rod e1 is provided with a first sliding sleeve e2 and a second sliding sleeve e3 in a sliding way.
The upper ends of two first front and rear swing rods d1 are respectively and rotatably mounted at the upper ends of two left and right shrinkage screw rods b1, the lower ends of two first front and rear swing rods d1 are simultaneously and rotatably mounted on a first sliding sleeve e2, the upper ends of two second front and rear swing rods d3 are simultaneously and rotatably mounted at the upper end of a guide rod e1, and the lower ends of two second front and rear swing rods d3 are respectively and rotatably mounted between the two first front and rear swing rods d 1. The upper ends of two first left and right swing rods d2 are respectively and rotatably mounted at the upper ends of two front and rear shrinkage screw rods c1, the lower ends of two first left and right swing rods d2 are simultaneously and rotatably mounted on a second sliding sleeve e3, the upper ends of two second left and right swing rods d4 are simultaneously and rotatably mounted at the upper end of a guide rod e1, and the lower ends of two second left and right swing rods d4 are respectively and rotatably mounted between the two first left and right swing rods d 2. The guide rod e1 is supported by means of two second front and rear swing rods d3 and two second left and right swing rods d4, so that the guide rod e1 stands in the middle of the rectangular array.
The two first front and rear swing rods d1 are matched with the two first left and right swing rods d2 to position the horizontal position of the axis of the guide rod e 1. When the rectangular overhaul room for electric power rush repair is folded in the left-right direction, the second sliding sleeve e3 moves downwards, and the two second left and right swing rods d4 rotate towards the guide rod e1 and approach to each other simultaneously. When the rectangular overhaul room for electric power emergency repair is folded in the front-back direction, the first sliding sleeve e2 moves downwards, and the two second front and rear swing rods d3 rotate towards the guide rod e1 and approach.
In this embodiment, the length of the first front and rear swing link d1 is greater than that of the first left and right swing link d2, so that the vertical direction moving range of the first sliding sleeve e2 in the folding and unfolding switching process of the rectangular maintenance room for power first-aid repair is greater than that of the second sliding sleeve e3, and therefore, the first sliding sleeve e2 is arranged below the second sliding sleeve e 3.
In order to further compensate the difference of the rotation ranges of the first front-back swing rod d1 and the first left-right swing rod d2 caused by the length difference, when the rectangular overhaul room for power emergency repair is completely folded, two second front-back swing rods d3 and two second left-right swing rods d4 can be simultaneously drawn close to the guide rod e1, a waist-shaped hole is formed in the middle of the first left-right swing rod d2, the lower end of the second left-right swing rod d4 is located at the waist-shaped hole, and the lower end of the second left-right swing rod d4 slides and rotates at the waist-shaped hole, so that the moving range of the second left-right swing rod d4 is increased.
In addition, in the embodiment, because the vertical heights of the two first motors and the two second motors are unchanged, the edge of the ceiling can be fixed on the first motors and the second motors so as to keep the height of the edge of the ceiling unchanged, so that the edge of the ceiling does not contact with the ground to be polluted, and the ceiling is kept clean.
