Problems solved by technology

[0002] 1. The original central cabinet manufacturer followed the general-purpose trolley of the switch cabinet with low structural strength, which happened during the operation and maintenance operation, and there were many cases of circuit breaker falling and personnel injury cases
[0003] 2. The structure of the conventional general-purpose trolley is unreasonable, and it is difficult to adjust during the actual operation on site
[0005] 4. Poor versatility, various general-purpose vehicles on site occupy a large area, and often only 1 or 2 vehicles are actually usable, and the operation efficiency is low
[0006] 5. The bottom of the conventional general-purpose trolley is not hollowed out, so it is impossible to repair and test the bottom structure of the circuit breaker

Embodiment

[0033]Embodiment: The mobile base 1 is moved to the position of the central cabinet through the universal wheel 2, and the hydraulic cylinder 10 can be conveniently controlled through the lifting handle 4 and the lowering handle 5, so that the hydraulic cylinder 10 can push the fixed support rod 7 and the movable support rod 8 Lifting movement, when the lowering handle 5 is not in use, you can push the lowering handle locking mechanism 24 so that the lowering handle locking mechanism 24 is movably snapped on the top of the lowering handle 5, so that it will not cause damage to the lifting handle 4. Influence, the movable support rod 8 slides on the limit bracket 6 through the movable collar 9 to adjust the distance from the fixed support rod 7, after adjusting the platform chassis 14 to the same height as the central cabinet, the platform can also be fine-tuned by adjusting the lifting adjustment screw 15 The height of the chassis 14, the height of the platform chassis 14 can b...

Abstract

The invention discloses a 10KV(20KV) centrally installed switchgear breaker running dolly in the technical field of centrally installed switchgears. The dolly comprises a movable pedestal, universal wheels are arranged in the bottom of the movable pedestal, a fixed frame is arranged in the left end of the movable pedestal, a lifting handle is movably arranged in the inside wall of the fixed frame,a declining handle is movably arranged under the lifting handle, a declining handle locking mechanism is movably arranged in the outer wall of the front end of the fixed frame, a limiting support isarranged in the top of the movable pedestal, and movable and fixed support bars are movably arranged in the outer wall of the limiting support. The dolly is suitable for high tension switchgears of different manufacturers, the bottom of a breaker can be inspected, maintained and tested simply via an additional maintenance function, different types of switchgears can be operated, adjustment is convenient and rapid, it is not required to replace the dolly when the switchgears in different types are operated, the risk that a handcart falls of in the operation process is avoided, and the whole operation, transport and maintenance cost of the high tension switchgear is reduced.

Description

technical field [0001] The invention relates to the technical field of central cabinets, in particular to a 10KV (20KV) central cabinet circuit breaker operating trolley. Background technique [0002] 1. The original central cabinet manufacturer followed the general-purpose trolley of the switch cabinet with low structural strength. During the operation and maintenance operation, there were many cases of circuit breaker falling and personnel injury. [0003] 2. The structure of the conventional general-purpose trolley is unreasonable, and it is difficult to adjust during the actual operation on site. [0004] 3. For different manufacturers, cabinets with different cabinet widths and different heights need to use corresponding special-purpose universal trolleys. [0005] 4. Poor versatility. All kinds of general-purpose vehicles on site occupy a large area, and often only 1 or 2 vehicles are actually usable, and the operation efficiency is low. [0006] 5. The bottom of the...
