DETAILED DESCRIPTION

[0019] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0020] like Figure 1-4As shown, the present invention proposes a substation fault inspection and maintenance device, including a base 1 and an inspection platform 5. A driving wheel is installed below the base 1. The driving wheel can be a powered electric running wheel 11, and the battery assembly of the electric running wheel 11 can be installed in the base 1. In addition, a counterweight block is also provided in the base 1 to improve the stability of the entire inspection and maintenance device. A lifting mechanism is installed above the base 1, and a support platform 3 is installed horizontally above the lifting mechanism. The lifting mechanism includes two groups of support rod assemblies symmetrically arranged in front and back, each group of support rod assemblies includes a first support rod 22 and a second support rod 21 which are connected together in rotation in the middle. The right ends of the two parallel first support rods 22 are installed on the base 1 at the bottom and rotated, and the left ends are installed on the first rotating shaft 24 with an upward tilt. The first rotating shaft 24 is arranged horizontally in front and back, and the two ends thereof are respectively connected to the corresponding first sliders 23 for rotation. The first slider 23 is installed at the bottom of the supporting platform 3 for horizontal sliding left and right; the right ends of the two parallel second support rods 21 are installed on the supporting platform 3 at the top and rotated, and the left ends thereof are respectively connected to the second rotating shaft 26 for rotation downward. The two ends of the second rotating shaft 26 arranged horizontally in front and back are respectively connected to the second sliders 27 for rotation. The second slider 27 is installed above the base 1 for horizontal sliding left and right; the middle part of the second rotating shaft 26 is installed with a telescopic cylinder 25 for rotation. The piston rod of the telescopic cylinder 25 is connected to the third rotating shaft 28 with an upward tilt. The third rotating shaft 28 is arranged horizontally on the upper part of the two first support rods 22 in front and back. In specific implementation, the telescopic cylinder 25 can adopt a hydraulic cylinder structure.

[0021] The sliding cooperation of the first slider 23 and the second slider 27 can improve the stability of the first support rod and the second support rod when they are rotated. When the telescopic cylinder 25 is extended, the piston cylinder of the telescopic cylinder 25 can lift the upper end of the first support rod 22 through the third rotating shaft 28, and at the same time, under the sliding limit of the first slider 23 and the second slider 27, the first support rod and the second support rod are driven to rotate and swing, thereby lifting the supporting platform 3, the maintenance platform 5 and other components upward to achieve the lifting action of the maintenance platform 5. When the operating height of the maintenance platform 5 needs to be lowered, the piston rod of the telescopic cylinder 25 can be driven to retract, and the operation is very simple and convenient.

[0022] A horizontal moving mechanism is provided on the supporting platform 3, and the maintenance platform 5 is installed on the horizontal moving mechanism; the horizontal moving mechanism includes a first horizontal transverse moving assembly and a second horizontal transverse moving assembly, the second horizontal transverse moving assembly is installed at the action end of the first horizontal transverse moving assembly, and the maintenance platform 5 is installed above the action end of the second horizontal transverse moving assembly; the first horizontal transverse moving assembly is installed on the supporting platform 3 and drives the second horizontal transverse moving assembly and the maintenance platform 5 to move horizontally left and right; the second horizontal transverse moving assembly is used to drive the maintenance platform 5 to move horizontally forward and backward.

[0023] Specifically, the first horizontal lateral movement assembly includes two parallel screw rods 61, which are horizontally mounted on the support platform 3 and connected to the corresponding driving motor 62. A movable plate 4 is movably mounted above the two screw rods 61, and the movable plate 4 is horizontally mounted on the support platform 3 for sliding movement. Two slide rails 31 are horizontally mounted above the support platform 3 along the left and right directions. The two slide rails 31 are parallelly mounted on the front and rear sides of the two screw rods 61. Two track sliders 43 are fixed at the bottom of the movable plate 4, and the track sliders 43 are slidably mounted on the corresponding slide rails 31. The movable plate 4 is horizontally fixed between the track sliders 43 of the two slide rails 31. A rotating rod is vertically mounted in the middle of the movable plate 4, and a first gear 63 is coaxially fixed at the lower end of the rotating rod. The first gear 63 is arranged between the two screw rods 61 and its front and rear sides are respectively meshed with the corresponding screw rods 61.

[0024] When the driving motor 62 provides power to drive the two screw rods 61 to rotate in the same direction, since the first gear 63 is respectively engaged with the two screw rods 61 on both sides, when the two screw rods 61 rotate forward or reverse synchronously, the first gear 63 itself does not rotate and can move horizontally left and right, and the movable plate 4 is driven to move horizontally left and right through the rotating rod, thereby realizing the left and right lateral adjustment of the second horizontal transverse movement component above and the maintenance platform 5, so that the device can adapt to more complex working environments.

[0025] The second horizontal lateral movement assembly includes a second gear 71 and a rack plate 72. The second gear 71 is coaxially fixed on the top of the rotating rod extending through the movable plate 4. Specifically, a first fixed block 41 is fixed on the left side of the movable plate 4. A through hole 410 is opened in the front and rear of the first fixed block 41. The slide bar 73 slides through the through hole 410. The slide bar 73 is arranged in parallel with the rack plate 72. The slide bar 73 plays a role in strengthening stability and can provide stable support for the upper maintenance platform 5. The rack plate 72 is horizontally slidably installed on the movable plate 4 along the front and rear directions and meshes with the second gear 71. The movable plate 4 is also fixed with a second fixed block 42. A T-shaped slot 420 is opened in the front and rear of the second fixed block 42 near the second gear 71. A T-shaped clamping portion 721 is provided on the rack plate 72. The clamping portion 721 slides in the T-shaped slot 420. The sliding cooperation between the clamping portion 721 and the T-slot 420 can effectively limit the forward and backward movement of the rack plate 72, thereby improving the stability of the rack plate 72 during movement. The sliding rod 73 and the front and rear ends of the rack plate 72 are vertically fixedly connected with connecting blocks 74, and the bottom of the maintenance platform 5 is fixedly mounted on the two connecting blocks 74.

[0026] When the two screw rods 61 rotate asynchronously (i.e. one rotates forward and the other rotates reversely) driven by the motor, the first gear 63 does not move in the horizontal direction and can rotate in situ. The rotation of the first gear 63 drives the second gear 71 to rotate synchronously through the rotating rod, so that the rack plate 72 meshing with the second gear 71 can slide horizontally in the front-to-back direction under the sliding cooperation between the clamping portion 721 and the T-slot 420, thereby driving the sliding rod 73 and the connecting blocks 74 at both ends to move forward and backward synchronously, thereby realizing the front-to-back horizontal adjustment of the upper maintenance platform 5, so that the device can adapt to the fine-tuning movement of different restricted working spaces, thereby significantly improving the maintenance work efficiency.

[0027] A plurality of guardrails are arranged around the periphery of the maintenance platform 5, and the guardrails include a plurality of vertically arranged lifting rods 51 and crossbars 52, the bottom of the lifting rods 51 is fixed on the maintenance platform 5, and the crossbars 52 are horizontally fixed to the telescopic ends above the lifting rods 51. Specifically, the lifting rods 51 include a sleeve 511 and a telescopic rod 512, the bottom of the sleeve 511 is fixed on the maintenance platform 5, the telescopic rod 512 is slidably sleeved in the sleeve 511, and the crossbar 52 is fixed to the top of the telescopic rod 512; when the present invention is implemented, at least four lifting rods 51 at the four corners of the maintenance platform 5 are provided with locking and adjusting components, and the locking and adjusting components include a fixing pin 5111, and a plurality of pin holes 5120 are evenly spaced on the telescopic rod 512 along its length direction, and the fixing pin 5111 passes through the sleeve 511 and is inserted into the pin hole 5120 on the telescopic rod 512.

[0028] Since different maintenance personnel have different heights, during specific maintenance, the height of the guardrails around the maintenance platform 5 will affect the maintenance efficiency of the maintenance personnel. If the height of the guardrail is too low, there will be certain safety risks, while if the guardrail is too high, it will hinder the maintenance work. The present invention can effectively adjust the height of the guardrail by changing the height of the lifting rod 51 and using the fixing pin 5111 of the locking and adjusting assembly to penetrate into the pin hole 5120 for locking, so that the height of the guardrail can be adapted to the maintenance work of maintenance personnel of different heights, thereby significantly improving the maintenance efficiency.

[0029] When using the present invention, after moving the fault inspection and repair device to the bottom of the maintenance area, the maintenance personnel go up to the inspection platform 5 and adjust the height of the guardrails around the inspection platform 5 according to their own height by using the lifting rod 51 and the locking adjustment component to ensure a safe height while avoiding interference with the operation; then drive the telescopic cylinder 25 of the lifting mechanism to extend, and cooperate with the first support rod 22 and the second support rod 21 to lift the support platform 3 and the inspection platform 5 to the height of the maintenance area; then control the drive motor 62 and use the first horizontal transverse movement component to adjust the horizontal position of the inspection platform 5 in the left and right directions, and then use the second horizontal transverse movement component to adjust the horizontal position of the inspection platform 5 in the front and rear directions, so that the inspection platform 5 can effectively adapt to the problem of limited space in the maintenance area, thereby significantly improving the maintenance efficiency.
