Description

Technical Field

[0001] The utility model relates to on-site maintenance and transportation equipment for a transformer substation or a converter station, in particular to a manned device for a transformer substation or converter station transport vehicle. Background Art

[0002] During the construction or maintenance of a substation or converter station, workers are required to work at height. Since the construction site of a substation or converter station is complex and has many related equipment, manned vehicles often need to pass through a complex and crowded environment during the operation. Using conventional manned vehicles makes the operation process difficult and not adaptable.

[0003] Through searching, technical documents of manned transport vehicles have been disclosed in the prior art. For example, the invention patent publication document with the publication number "CN114634141A" and the name "A manned lifting device". It involves a manned lifting device, including a vehicle body, a ladder, a manned platform, a tower body and a crane; crawlers are provided on both sides of the bottom of the vehicle body; the tower body is rotatably installed on the top of the vehicle body along the vertical direction; the first end of the crane is pivotally connected to the tower body; the middle part of the crane is connected to the tower body through a first supporting mechanism; the ladder is installed on the top of the vehicle body; the top of the ladder is telescopically connected to the manned platform. This comparative document realizes the integration of manning and cargo, but the lateral space occupied by the vehicle is large, and the stability of the manned platform is not strong.

[0004] For example, the invention patent publication document with the publication number "CN114852888A" and the name "A lifting device combined with a lifting arm and a lifting platform" discloses a lifting device combined with a lifting arm and a lifting platform, including: a vehicle body, a lifting arm and a lifting platform; the lifting arm includes: a vertical arm, a horizontal arm, a first motor and a second motor; the vertical arm is vertically arranged on the vehicle body and can be rotatably arranged along a horizontal plane; the first end of the horizontal arm can be rotatably connected to the top of the vertical arm along a vertical plane, and a hook is arranged at the second end; the first motor is used to drive the horizontal arm to rotate; the second motor is used to drive the vertical arm to rotate; the lifting platform includes: a bottom platform, a cross lifting frame, an end platform, a third motor and a manned platform; the bottom platform is arranged on the vehicle body; the cross lifting frame is arranged on the bottom platform; the end platform is arranged on the top of the cross lifting frame; the manned platform can be rotatably arranged on the end platform; the third motor is used to drive the manned platform to rotate. The transport equipment disclosed in the comparative document can carry people and lift heavy objects, but its manned platform is vertically lifted, and it is unable to lift workers to the work site in some narrow or large-span work scenarios.

[0005] For example, the utility model authorization announcement document with the publication number "CN213537194U" and the name "A multifunctional substation equipment micro maintenance vehicle". A multifunctional substation equipment micro maintenance vehicle is disclosed. It is equipped with a rubber crawler chassis at the bottom of the main frame, hydraulic legs at the four corners of the main frame, a generator is fixed in the center of one side of the main frame, and there are a lift and a hydraulic pump station in front and behind the generator respectively. At the bottom of the other side of the main frame are an air compressor and a tool box, and at the top is a rotating telescopic micro crane. A traction winch is also fixed at the front end of the main frame, and a standing pedal and control panel are fixed at the rear end. All kinds of control valve stems, buttons or switches are connected by pipelines and installed on the control panel. The comparative document proposes a miniature substation equipment maintenance vehicle, but does not propose relevant technical solutions for manned lifting.
