The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail.Following examples are used to explain the utility model, but are not used for limiting the scope of the utility model.
Shown in Fig. 1-5; Holdout device under a kind of rotary machine; Comprise mounting bracket 1 and dash plate 2, said dash plate 2 is installed on outside the car projecting plane of both sides at the bottom of lift car 3 sedan-chairs, and mounting bracket 1 is installed on the elevator hoistways two side near bottom end position; Mounting bracket 1 is provided with revolving bar 4, and the mounting bracket 1 of revolving bar 4 belows is provided with reset switch 5 and step switch 6.
Holdout device under the rotary machine of the utility model, an end of said revolving bar 4 is fixed on the mounting bracket 1, and the top of revolving bar 4 other ends is provided with energy disperser 7, and the below of energy disperser 7 is provided with the strut bar 8 that is fixed on the revolving bar 4.
Holdout device under the rotary machine of the utility model; Be equipped with knock hole 9 on front side, rear side and the mounting bracket 1 near dash plate 2 sides of said revolving bar 4 and mounting bracket 1 junction, the bottom of revolving bar 3 is provided with the locating dowel pin 10 that cooperatively interacts with knock hole 9 near mounting bracket 1 place.
The revolving bar 4 of holdout device must be through pull-up under the rotary machine of the utility model, and its locating dowel pin 10 could break away from the normal position and rotate, and revolving bar 4 forwards the control position place to, and its locating dowel pin 10 could insert knock hole 9, makes this device in running order; Energy disperser 7 is equipped with on revolving bar 4 tops, rigidity contact when avoiding lift car 3 descending, and strut bar 8 is equipped with in the bottom, and strut bar 8 bottoms extend to the energy disperser end face at the control position place, bear the descending impact load of car; Said dash plate 2 is loaded on the both sides outside the projecting plane, lift car 3 bottom, and its center and pit energy disperser, strut bar 8 are corresponding; Said reset switch 5 moves during pull-up below revolving bar 4 entopic locating dowel pins 10, just resets automatic cutout and the normal operating loop of connecting elevator when original position is fallen; Step switch 6 moves when falling below the locating dowel pin 10 of revolving bar 4 control positioies, resets during the original position pull-up, connects and cut off the inspection travel loop of elevator.The locating dowel pin 10 of revolving bar 4 link mutually with reset switch 5, step switch 6, except the assurance personnel have enough survival spaces when the pit upkeep operation, has also avoided personnel's maloperation effectively, and has forgotten the risk that resets after working.
Reset switch closed (resetting down) during the following holdout device normal condition of the utility model connects relay K A5, and step switch 6 breaks off (locking down).1) when the following holdout device pull-up of any side, reset switch 5 moves, and contact (locking down) breaks off, relay K A5 coil losing electricity, and the line of " the normal operation " end of the KA5 contact open control housing of relay, elevator can not normally move, can not inspection travel.When 2) needing inspection travel; Last holdout device must get into control position, and step switch 6 closures are connected the maintenance loop; Again change-over swith SA2 is switched to the maintenance loop; Switch 1-2 connects the descending line of maintenance of control housing, makes control housing can normally receive the maintenance downlink command, realizes the inspection travel function.3) after upkeep operation is accomplished, need the maintenance loop is cut off in all pull-ups and rotate to normal position and insert locating dowel pin down of the following holdout device of both sides; And reset switch 5 actions are closed; Relay K A5 coil gets electric, the KA5 closing of contact of relay, the line of " normal operation " end of connection control housing.The operating personnel switches to normal loop with change-over swith SA2 after leaving pit again, and elevator just returns to normal operating condition.
The above only is the preferred implementation of the utility model; Should be understood that; For those skilled in the art; Under the prerequisite that does not break away from the utility model know-why, can also make some improvement and modification, these improvement and modification also should be regarded as the protection domain of the utility model.
