Description

Technical Field

[0001] The utility model relates to the field of water turbine maintenance, in particular to a folding scooter for inspecting the lower end of a stator. Background Art

[0002] The maintenance work of the lower windshield of the stator of the turbine mainly includes the inspection of the stator core and slot wedge, the cleaning and inspection of the lower end of the wire rod and the insulation box, the inspection of the magnetic pole, the inspection of the stator and rotor air gap, etc. The current maintenance method for these works is to open several manhole doors on the lower windshield, and the maintenance personnel crawl around the main shaft on the lower windshield to carry out a circle inspection of the lower end of the stator and other items.

[0003] The above operation method has the following disadvantages:

[0004] 1. The maintenance area is narrow and inconvenient to move around. The lower windshield passage is only wide enough for an adult man to crawl through. When conducting inspections, maintenance personnel need to lie on their backs and conduct more than one round of inspections. They need to walk around the entire unit horizontally for multiple times, which puts great pressure on the maintenance personnel's physical strength and maintenance efficiency.

[0005] 2. Insufficient working lighting. When inspecting the wire rods and the core slot wedges, the lighting effect of the headlights and lamps is not obvious due to the angle, which is not conducive to detailed inspection. There are many corners between the wire rods that cannot be inspected, which may lead to inadequate inspection of hidden dangers.

[0006] 3. The working posture is awkward and not conducive to inspection work. When inspecting the oblique line section at the lower end of the generator stator, the personnel can only rely on the waist support and tilt their heads to keep their sight parallel to the wire rods to conduct inspections between the wire rods, which makes the work difficult. Summary of the invention

[0007] The technical problem to be solved by the utility model is to provide a folding scooter for inspecting the lower end of a stator, which allows maintenance personnel to flexibly and labor-savingly perform circular movements on the lower windshield, while providing waist support during cleaning and inspection work, thereby solving the problems of inconvenient movement, difficult operation and low work efficiency for personnel in a narrow and harsh working environment.

[0008] In order to solve the above technical problems, the technical solution adopted by the utility model is: a folding scooter for inspecting the lower end of a stator, comprising a frame, a plurality of sets of universal wheels are arranged at the bottom of the frame, a cushion and a backrest are arranged on the frame, a rotating shaft is arranged at one end of the backrest close to the cushion, the rotating shaft is rotatably mounted on the frame, the bottom of the backrest is supported by a supporting mechanism, the supporting mechanism comprises a supporting cross bar, supporting vertical bars are arranged at both ends of the supporting cross bar, a hinged rod is arranged at the end of the supporting vertical bar, the hinged rod is rotatably mounted on the frame, a limiting seat is arranged at the bottom of the backrest, and a plurality of clamping grooves for clamping with the supporting cross bar are arranged on the limiting seat.

[0009] In a preferred solution, the limit seat includes a mounting plate, two sets of clamping plates are provided on the mounting plate, a slide groove is provided on the clamping plate, the supporting cross bar is passed through the slide groove, and the clamping groove is arranged on the inner side of the slide groove and communicated with the slide groove.

[0010] In a preferred embodiment, the frame includes a first frame and a second frame, and a hinged ear plate is provided at the bottom of one end where the first frame and the second frame are spliced, and the end of the hinged ear plate is hinged by a hinge shaft, and multiple groups of cushions are provided, which are respectively arranged on the first frame and the second frame.

[0011] In a preferred solution, a lighting lamp is provided at one end of the frame close to the backrest.

[0012] The utility model provides a folding scooter for inspecting the lower end of a stator, which has the following beneficial effects:

[0013] 1. Greatly reduce the difficulty of operation. In the general maintenance process, the maintenance personnel need to check the stator end more than once. Using the scooter to slide in the windshield channel instead of crawling in the narrow channel greatly saves the physical consumption of the personnel and reduces the difficulty of activities and inspections.

[0014] 2. Greatly improve the lighting environment. For some narrow areas, such as between the wire rods, there are many corners that cannot be checked normally using headlights or conventional lamps, while the use of bendable lighting can illuminate every corner, freeing your hands, which is very conducive to carefully inspecting the ends of the stator wire rods.

[0015] 3. Lightweight and easy to carry. The main body is made of aluminum alloy and plastic, which ensures strength and can be used relatively lightly at the maintenance site. It can be folded and placed when not in use for easy storage and management.

[0016] 4. The scooter allows maintenance personnel to move in circles on the lower windshield flexibly and labor-savingly, while providing waist support during cleaning and inspection work, solving the problems of inconvenient movement, difficult operation and low work efficiency for personnel in narrow and harsh working environments.
