Fig. 2 is the structural representation after embodiment of the present invention motor drive mechanism safety device and motor drive mechanism assemble.
Wherein, 1: motor drive mechanism; 2: base plate; 3: operating grip jack; 4: support; 5: drive mandrel; 6: sensitive switch.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Fig. 1 shows the structural representation of the present embodiment motor drive mechanism erecting device, Fig. 2 be motor drive mechanism safety device and motor drive mechanism are assembled after structural representation.With reference to diagram, this motor drive mechanism safety device is used for being assemblied in ring main unit motor drive mechanism 1, for motor drive mechanism 1 provides safe operating environment.The sensitive switch 6 that described safety device comprises base plate 2 and is arranged on described base plate 2, described base plate 2 is for being assemblied in motor drive mechanism 1, described sensitive switch 6 is near motor drive mechanism operating grip jack 3, and be connected with the main circuit power (not indicating in figure) of motor drive mechanism 1, to control the cut-out of described main circuit power when operating grip update handle socket 3, when operating grip extracts operating grip jack 3, recover the connection of described main circuit power.
Particularly, operating grip insert with the cut-out of extracting operating grip jack 3 pairs of sensitive switches 6 be communicated with effect, realize by various ways.First, by means of operating grip, operating grip outer wall arranges outstanding touching part, when operating grip update handle socket 3, touching part touches sensitive switch 6, realizes the cut-out that sensitive switch 6 controls described main circuit power; When operating grip extracts operating grip jack 3, touching part leaves sensitive switch 6, recovers the connection of described main circuit power.
Or, described base plate 2 arranges transmission mechanism, transmission mechanism is between described sensitive switch 6 and the operating grip jack 3 be adjacent, during operating grip update handle socket 3, described transmission mechanism is moved to described sensitive switch 6, by sensitive switch 6, described main circuit power is cut off; When operating grip extracts operating grip jack 3, transmission mechanism resets, and sensitive switch 6 makes described main circuit power recover to be communicated with.
Described transmission mechanism comprises fixing support 4 on a base plate 2, and be arranged on moveable drive mandrel 5 in described support 4, back-moving spring (not indicating in figure) is provided with between described drive mandrel 5 and described support 4, when operating grip update handle socket 3, the wall thickness of operating grip is filled with the gap between itself and transmission mechanism and has rich thickness, this thickness can be conflicted described drive mandrel 5, make drive mandrel 5 near described sensitive switch 6 and active force is applied to it, thus cutting off described main circuit power by sensitive switch 6; When operating grip extracts operating grip jack 3, described drive mandrel 5 by External Force Acting, is not resetted by back-moving spring, and away from described sensitive switch 6, sensitive switch 6 makes described main circuit power recover to be communicated with.
Wherein, described support 4 is set to column cylinder, and wherein centre axis parallel is in base plate 2 surface; It is outside that described drive mandrel 5 gives prominence to described support 4 near the one end of the operating grip installing hole 3 be adjacent, and this outstanding end convenient operation handle applies active force to it.The central shaft of described support 4 is parallel to the central shaft of described drive mandrel 5, back-moving spring can be arranged perpendicular to the central shaft of support 4 and drive mandrel 5, so that when drive mandrel 5 is subject to the applied external force along its axis direction, by spring elongation, overcome the active force of spring and move along its axis direction, after said external active force removes, drive mandrel 5, by the effect of spring restoring force, is resetted.
In the present embodiment, based on the quantity of operating grip jack 3, correspondingly described sensitive switch is set to two, make the corresponding operating grip jack 3 of a sensitive switch 6, and sensitive switch 6 is arranged near the operating grip jack 3 corresponding with it, when operating grip jack 3 quantity changes, the quantity of corresponding change sensitive switch 6.Meanwhile, if employing transmission mechanism assists the break-make of carrying out main circuit power to control, the quantity of transmission mechanism and the quantity of sensitive switch 6 also should be consistent.
As can be seen from the above embodiments, the present invention is by being provided with the sensitive switch near operating grip jack, and sensitive switch is connected with the main circuit power of motor drive mechanism, can when operating grip update handle socket, main circuit power is cut off by the action of operating grip, a distant place or the operation that just connects can not be performed, avoid damage operating personnel and damage motor drive mechanism, when operating grip extracts operating grip jack, main circuit power automatically replies connection, this apparatus structure is simple, practical, substantially increase the overall security of ring main unit motor drive mechanism.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
