Abstract
The utility model relates to a switch cabinet rapidly grounding trolley comprising a chassis, a frame, a contact arm component, an operating handle, an operating shaft, a transmission mechanism, a grounding knife and a cam. The frame is fixed on the chassis; the contact arm component is fixed on the frame; the central part of the cam is rotatably fixed on the frame through a rotating shaft; the grounding knife is fixed at the edge of the cam; the operating shaft is rotatably fixed on the frame; the operating handle is connected with the front end of the operating shaft; and the rear end of the operation shaft is connected with the cam through the transmission mechanism. The switch cabinet rapidly grounding trolley is characterized by further comprising an elastic element; and one end of the elastic element is connected with the edge of the cam and the other end thereof is connected with the lower end of the frame. Compared with the prior art, the switch cabinet rapidly grounding trolley has the advantages of closing off the short circuit current and rapid grounding when a running electric system has failures and carries current during grounding, and having extremely convenient use.
Description
Technical field
The utility model relates to a kind of switch cubicle, more specifically to the quick ground connection dolly of a kind of switch cubicle.
Background technology
Existing switch cubicle ground connection dolly, the speed that close the pass is fast inadequately, when the electric power system of operation is broken down, when the ground connection process has electric current, can't satisfy and realize quick ground connection.
Summary of the invention
The purpose of this utility model is that prior art is improved, and provides a kind of switch cubicle quick ground connection dolly, ground connection fast, and the ability of short circuit current is closed in the pass that has, and the technical scheme of employing is as follows:
The quick ground connection dolly of switch cubicle of the present utility model, comprise the chassis car, framework, the contact arm assembly, operating grip, operating axis, transmission mechanism, the ground connection cutter, cam, frame fixation is on the car of chassis, the contact arm assembly is fixed on the framework, the middle part of cam is fixed on the framework by rotating shaft is rotating, the ground connection cutter is fixed on the edge of cam, operating axis is rotating to be fixed on the framework, the front end of operating grip attended operation axle, the rear end of operating axis connects cam by transmission mechanism, it is characterized in that: also comprise flexible member, flexible member one end connects the edge of cam, other end connecting frame lower end.When need not ground connection, rotating operating handle, drive cam rotation by transmission mechanism, make the ground connection heel rotation, the ground connection cutter is terminal to rise, after cam rotation was crossed the dead point, the pulling force of flexible member can't spur the cam counter-rotation when not being subjected to other external force effect, and cam and ground connection cutter rest on open position; In the time of the quick ground connection of needs, the opposite spin operating grip, drive the cam counter-rotation by transmission mechanism, make the ground connection heel counter-rotation, the ground connection cutter is terminal to descend, after the cam counter-rotation was crossed the dead point, the pulling force of flexible member pulling cam is quick rotation in the other direction, up to ground connection cutter closure.
A kind of scheme, described transmission mechanism is a gear drive, gear drive comprises first bevel gear and second bevel gear, first bevel gear (bevel gear also can be called bevel gear) is fixed on the operating axis rear end, second bevel gear is coaxial fixing with cam, first bevel gear and the engagement of second bevel gear.
Another kind of scheme, described transmission mechanism comprises worm gear, worm screw, and worm screw is connected with operating grip, and worm gear is coaxial fixing with cam, worm gear and worm engaging.Described transmission mechanism can also adopt other similar transmission mechanism.
Described flexible member is a spring.Also can adopt other similar flexible member.
The utility model beneficial effect against existing technologies is, breaks down when the electric power system of operation, when the ground connection process has electric current, can close and close short circuit current, and ground connection is very easy to use fast.
