Description

The mechanical lock device of Manual isolation switch

Technical field

The utility model is related to a kind of mechanical lock device of Manual isolation switch, for the machine of self-locking between high ferro, subway Tool device, it is to avoid padlock gets rusty and causes stubborn problem.

Background technology

Current China's Manual isolation switch is widely used in high ferro, subway, when early stage China's subway and light rail are built manually every Leave the mode closed and take unit non-packed padlock always.As power system is to carrying that the q＆r of distribution system is required Height, to the performance requirement of high-tension switch gear also more and more higher, common padlock often occurs getting rusty or corroding the phenomenon do not opened, In order to meet demand of the today's society to high quality of products, this mechanical lock device exactly meets this technical requirements and designs.

The content of the invention

For the deficiency in structure in the prior art, the purpose of this utility model is to provide a kind of Manual isolation switch Mechanical lock device, manual-operating mechanism lock shaft is pinned with mechanical lock, rather than with traditional padlock, is beneficial to solution lock core of padlock Get rusty or corrode and do not open.

To achieve the above object, the technical solution adopted in the utility model is to provide a kind of machinery of Manual isolation switch Locking device, the mechanical lock device is arranged at the base side plate of man-operated mechanism, wherein：The mechanical lock device include by bottom end cover, Upper end cover, back plate, left plate, right plate, mechanical axis, mechanical lock key；Left plate, right plate are welded in the two of back plate respectively Side, upper end cover and bottom end cover are connected at the two ends of back plate respectively, and upper end cover and bottom end cover and left plate, right plate is corresponding connects, Mechanical axis is inserted into right plate to mechanical axis end cap from left plate to be close to left plate, mechanical lock hole position is immediately below mechanical axis At 45mm, twisting key to dead bolt overlaps with mechanical axis groove.

Effect of the present utility model is that the mechanical lock device of the Manual isolation switch solves common lock core of padlock and gets rusty Do not open problem, reduce mechanism size, reduces cost is simple to operate, and stable action, mechanism is compact.Improve security.Will Mechanical lock loads in side plate, in addition to more spaces are saved, also add the compactness of lock shaft.The mechanical lock device is convenient to be operated, The condition of work of disconnecting switch is improved, the reliability of switch is improve, service life is extended.

Specific embodiment

The mechanical lock device of Manual isolation switch of the present utility model is illustrated with reference to accompanying drawing.

The mechanical lock device structure of Manual isolation switch of the present utility model is that the mechanical lock device is arranged on hand-machine At the base side plate of structure, the mechanical lock device is included by bottom end cover 1, upper end cover 2, back plate 3, left plate 4, right plate 5, mechanical axis 6th, mechanical lock key 7；Left plate 4, right plate 5 are welded in the both sides of back plate 3 respectively, upper end is connected respectively at the two ends of back plate 3 The corresponding connection of lid 2 and bottom end cover 1, upper end cover 2 and bottom end cover 1 and left plate 4, right plate 5, mechanical axis 6 is inserted from left plate 4 It is close to left plate 4 to right plate 5 to mechanical axis end cap, at 45mm immediately below mechanical axis, twisting key is extremely for mechanical lock hole position Dead bolt overlaps with the groove of mechanical axis 6.

The mechanical lock device operation principle of Manual isolation switch of the present utility model is：Under normal operating conditions, by machine Tool axle 6 is penetrated to right plate 5 by left plate 4, now inserts a key into mechanical lock key hole 7, rotating machinery lock dead bolt and machinery The groove of axle 6 overlaps, and now locks mechanical lock device；When needing to open mechanical lock device, key is rotated to rightabout, Extracting mechanical axis 6 can open mechanical lock device.

As shown in figure 1, during the mechanical lock device structure fabrication of Manual isolation switch of the present utility model, at two side plates One square hole of 35x35 of milling, had not only saved cost but also had alleviated the weight of mechanism's side plate, while lock shaft is contracted by original 135mm Short is 90mm.When mechanical lock is closed, dead bolt has overlapping for 5mm or so with mechanical axis groove, and the fastening of mechanical axis is kept enough； When mechanical lock is opened, dead bolt is moved to mechanical axis rightabout, is not interfered with other parts.Left plate 4, right plate 5 With firm welding at 3 liang long side 6mm of back plate, at back plate 6mm concordantly, upper end cover 2 and bottom end cover 1 are welded at back plate 50mm for downside Connect, two sides are welded with left plate 4 and right plate 5, after polish smooth.

Mechanical axis 6 is inserted into right plate 5 to mechanical axis end cap from left plate 4 to be overlapped with left plate 4, the mechanical key of insertion Spoon, twisting key to dead bolt overlaps with the groove of mechanical axis 6, and now mechanical axis 6 is pinned and cannot be moved by mechanical lock 6, now Extracting key can pin mechanical axis；When needing to open switch, key is inserted, rotation dead bolt is separated with mechanical axis, extracts machine Tool axle is to open mechanical lock device.
