Description

Technical Field

[0001] This utility model relates to a foldable power maintenance platform, belonging to the technical field of power maintenance platform equipment. Background Technology

[0002] Power maintenance platforms are important tools used in power systems for the inspection and maintenance of power equipment. They are mainly used in substations, transmission lines, distribution equipment, and other locations. The design and functions of power maintenance platforms aim to improve maintenance efficiency, ensure operational safety, and reduce labor costs.

[0003] CN220769342U discloses "a power maintenance platform", which includes a maintenance platform; two first fixing rods, each rotatably connected to one side of the maintenance platform via a rotating shaft; two second fixing rods, each rotatably connected to one side of the maintenance platform via a rotating shaft, and each second fixing rod rotatably connected to the two first fixing rods via a rotating shaft; and a fixing mechanism, which includes a fitting groove, a spring groove, a fitting slider, a fixing groove, a sliding block, a telescopic spring, and an insertion block, to ensure the safety of maintenance personnel when performing maintenance on power equipment on the maintenance platform, and to save time in fixing the maintenance platform and improve maintenance efficiency by automatically fixing it after the two support legs of the maintenance platform are pulled apart.

[0004] The aforementioned patent utilizes an "outward-facing octagonal" structure to support the power maintenance platform. Existing power maintenance platforms mostly employ an outward-facing octagonal support, with the bottom in contact with the ground and the middle section secured by folding struts. During use, when operators stand and move above the platform, displacement can easily occur, causing the lower support legs to shift. This results in the platform being unstable during use, posing a safety hazard. Furthermore, existing power maintenance platforms are large and difficult to carry and store.

[0005] Therefore, it is necessary to improve the existing power maintenance platform. Utility Model Content

Each of the first folding plate and the second folding plate has a plurality of folding blocks and a plurality of locking block slots that match the folding blocks. Each of the first folding plate and the second folding plate has a plurality of fixing bolts at both ends and a limiting rod slot in the middle. The limiting rod slot has a plurality of symmetrical anti-detachment blocks in the middle and a plurality of swing top rods near the connecting shafts.

[0013] Furthermore, the strut includes a plurality of sleeve rods, with nested extension rods nested inside the sleeve rods. Both the sleeve rods and the nested extension rods are provided with at least five sets of through holes. The sleeve rods and the nested extension rods are connected by pins passing through the through holes. The upper end of the nested extension rod on the same side as the connecting base is connected by a bidirectional rotating top rod. The upper end of the nested extension rod is provided with an alignment block, and the bottom is embedded with an anti-slip block.

[0014] Furthermore, the nested extension rod is engaged between the limiting rod groove and the anti-detachment block, and the swinging top rod is engaged with the lower end of the nested extension rod.

[0015] Furthermore, the swing block near the first swing plate is engaged in the slot of the second swing plate via a connecting shaft, and the first and second swing plates are connected to the lower part of the auxiliary fixing frame by a fixing bolt.

[0028] Platform 1 includes a platform frame 11 and a nested railing 12. The nested railing 12 is nested on the platform frame 11 and is used to prevent operators from accidentally falling and improve the safety of the power maintenance platform.

[0029] The support assembly includes a plurality of telescopic slides 2 located below the connecting platform 6, an auxiliary retaining frame 3 located outside the telescopic slides 2, and support rods 5 located on the front and rear sides of the connecting platform 6. The support rods 5 and the rotation axis of the telescopic slides 2 are arranged perpendicularly. The telescopic slides 2 and the auxiliary retaining frame 3 are slidably engaged, and the telescopic slides 2 are hinged to the bottom of the platform frame 11. When not in use, they can be hinged and swung to fold and store the telescopic slides 2 and the platform frame 11, reducing the storage space of the power maintenance platform.

[0030] The support rod 5 includes a plurality of sleeve rods 51, and a nested extension rod 52 is nested inside the sleeve rod 51. The nested extension rod 52 is a telescopic structure. At least five sets of through holes 57 are evenly provided on the sleeve rods 51 and the nested extension rod 52. After the nested extension rod 52 is adjusted to the required length, the pin 54 is inserted into the aligned through holes 57 on the sleeve rods 51 and the nested extension rod 52 to complete the length adjustment of the sleeve rods 51 and the nested extension rod 52. The upper end of the nested extension rod 52 is provided with an alignment block 56, and the bottom is embedded with an anti-slip block 53.

[0031] The connecting base 6 has a platform 61 fixed to the center of the lower surface of the platform frame 11. Both the front and rear ends of the platform 61 have inner sliding grooves 63 for the lateral movement of the alignment block 56. A plurality of docking grooves 62 are provided in the center of the inner sliding grooves 63. The alignment block 56 is nested in the docking grooves 62. The docking grooves 62 are annular to facilitate the nesting of the alignment block 56. The support rod 5 is connected to the front and rear sides of the connecting base 6 by the alignment block 56 at the upper end of the nesting extension rod 52 nesting in the docking groove 62 on the connecting base 6.

[0032] The upper end of the nested extension rod 52 on the same side of the connecting base 6 is connected by a bidirectional rotating top rod 55. The alignment block 56 cooperates with the bidirectional rotating top rod 55 to realize the outward rotation of the support rod 5. The alignment block 56 moves laterally in the inner moving groove 63 to the top of both sides to complete the fixation of the upper end of the support rod 5.

[0033] The folding auxiliary frame plate 4 has a first folding plate 41 and a second folding plate 42, which are connected by a plurality of connecting shafts 43. Both the first folding plate 41 and the second folding plate 42 have a plurality of folding blocks 45 and a plurality of matching slots 46. When the folding auxiliary frame plate 4 needs to be folded up, the folding blocks 45 on the first folding plate 41 engage with the slots 46 on the second folding plate 42, and the folding blocks 45 on the second folding plate 42 engage with the slots 46 on the first folding plate 41, thus completing the folding of the folding auxiliary frame plate 4. Both the left and right ends of the first folding plate 41 and the second folding plate 42 have a plurality of fixing bolts 44 for securing the folding plate. The locking bolt 44 is used to fix the folding auxiliary support plate 4 below the auxiliary support frame 3, limit the auxiliary support frame 3, and prevent the power maintenance platform from moving or shifting during use. The auxiliary support rod 5 forms a limiting support to maintain strong support for the power maintenance platform. The first swing plate 41 and the second swing plate 42 are both provided with a limiting rod groove 47 in the middle. The limiting rod groove 47 is provided with a symmetrical plurality of anti-detachment blocks 48 in the middle. The limiting rod groove 47 is provided with a plurality of swing top rods 49 near the connecting shaft 43. The nested extension rod 52 is locked between the limiting rod groove 47 and the anti-detachment block 48. The swing top rod 49 swings to a suitable angle and abuts against the lower end of the nested extension rod 52.

[0034] This utility model allows for height adjustment of the power maintenance platform by adjusting the length of the telescopic slide 2 and the support rod 5.

[0035] The specific working principle of this utility model is as follows:

[0036] In use, the telescopic slide 2 below the platform frame 11 is vertically positioned, and the auxiliary retaining frame 3 is connected to the outside of the telescopic slide 2. The folded auxiliary retaining frame plate 4 is unfolded, so that the first folding plate 41 and the second folding plate 42 are parallel under the cooperation of the connecting shaft 43. The folded auxiliary retaining frame plate 4 is fixed to the bottom of the auxiliary retaining frame 3 by the fixing bolt 44. The alignment block 56 at the upper end of the nested extension rod 52 is nested into the docking groove 62 of the platform 61. The alignment block 56, in conjunction with the bidirectional rotating top rod 55, drives the support rod 5 to rotate, so that the alignment block 56 moves laterally to the top in the inner moving groove 63, realizing the outward rotation of the support rod 5, and adjusting the telescopic slide. 2. Extend the nested extension rod 52 to the required length. After extending to the appropriate length, insert the pin 54 through the through hole 57 on the nested extension rod 52 and the sleeve rod 51. The lower end of each nested extension rod 52 is respectively locked between the limit rod groove 47 and the anti-detachment block 48 on the first swing plate 41 or the second swing plate 42. Adjust the angle of the swing top rod 49 so that the swing top rod 49 is fixed to the rear surface of the nested extension rod 52. The installation of the power maintenance platform is completed. This can prevent the support rod 5 from shifting when the operator performs power maintenance on the platform 1. At the same time, it indirectly completes the auxiliary support of the platform 1 and improves the stability of the power maintenance platform.
