Abstract
The utility model discloses an improved controller automatic-locking backstop structure. The improved controller automatic-locking backstop structure comprises a spring bolt arranged on a handle of a controller; the spring bolt is matched with automatic-locking backstop devices arranged on a cover plate on the controller; the automatic-locking backstop devices are two symmetrical erect right triangle baffle blocks; the cover plate on the controller is provided with replaceable automatic-locking backstop device installation holes; the installation holes are provided with concave tables the peripheries of which are concave downward, and are provided with the replaceable automatic-locking backstop devices; the replaceable automatic-locking backstop are structurally two symmetrical erect right triangle baffle blocks arranged on a panel; the two right triangle baffle blocks are matched with the spring bolt on the handle of the controller; the top surface of the panel installed on the installation holes is in flush with the plate surface of the cover plate on the controller; the panel is fixedly connected to the concave tables of the installation holes by sunk screws. The improved controller automatic-locking backstop structure provided by the utility model can replace abraded automatic-locking backstop devices rapidly, shorten the overhauling time and reduce the maintaining expense, and can prolong the online service life of the controller.
Description
Technical field
The utility model belongs to the improvement of elevator machinery electric control system controller self-locking stop configurations, particularly a kind of improved controller self-locking stop configurations.
Background technology
The cam controller generally adopting in electric control system on elevator machinery at present, by controller contact, cam mechanism, protection housing, upper cover plate, handle and self-locking blocking means composition, in order to ensure the generation of the safety misadventure that controller causes because of operating personal maloperation, generally at controller upper shell, controller level centered beneath zero bit position is provided with self-locking blocking means, operating personal is after operation task completes each time, controller level need be returned to zero-bit, the namely midway location of self-locking blocking means, if do not applied certain downward bulb of defeating lower handle head, self-locking device will stop the motion of handle left and right directions, thereby can avoid because of people's maloperation or encounter because of carelessness personnel's injury that the Mechanism of crane misoperation that causes causes and the generation of safety misadventure.
The subject matter existing is as follows:
1. current controller self-locking blocking means is disposable welding production, due to controller frequently, operation repeatedly, will certainly cause the wearing and tearing of self-locking blocking means, after wearing and tearing, will cause this safety guard to lose efficacy, for misoperation fault is buried accident potential.
2. after the wearing and tearing of self-locking blocking means, because not meeting the requirement of equipment essential safety, need integral replacing, because the whole service life of controller in inspection at ordinary times, situation that adjustment work puts in place is longer, as the replacing causing because of the wearing and tearing of self-locking device, will cause the increase of cost of equipment maintenance.
Utility model content
The purpose of this utility model is to provide a kind of improved controller self-locking stop configurations, can realize the self-locking blocking means quick-replaceable to wearing and tearing, shortens the repair time, reduces service expenditure, can extend the online service life of controller.
The purpose of this utility model is achieved in that a kind of improved controller self-locking stop configurations, comprise the dead bolt arranging on controller level, dead bolt matches with the self-locking blocking means arranging on controller upper cover plate, self-locking blocking means is two symmetrical upright right-angled triangle blocks, removable self-locking blocking means mounting hole is being set on controller upper cover plate, periphery is being set on mounting hole to recessed concave station, removable self-locking blocking means is installed on mounting hole, the structure of removable self-locking blocking means is that two symmetrical upright right-angled triangle blocks are being set on flat board, two right-angled triangle blocks match with the dead bolt on controller level, be arranged on its end face of flat board on mounting hole concordant with the plate face of controller upper cover plate, flat board is fixed on the concave station of mounting hole by flathead screw.
The utility model is changed into the self-locking backstop mode on controller upper cover plate the mode of detachable replacing by the mode of original welding disposal molding, be convenient to the quick-replaceable of the self-locking blocking means to wearing and tearing in field maintemance operation.Controller upper cover plate in the time of Mold Making, prefabricated installation counterbore, and bored bolt mounting holes.When replaceable, backstop self-locking device is installed and can not be exceeded plane on upper shell, and bolt uses cross recessed countersunk head sscrew, and bolt hole all adopts counterbore design, ensures mounting plane always, does not affect former use function.When replaceable, backstop self-locking device can be made separately, and buying, for subsequent use as spare part separately.
The good effect producing after improving:
1. by improving the connection mode of controller self-locking blocking means, can solve the larger maintenance cost expenditure that controller integral replacing produces.
2. less as the relatively overall controller procurement price of the self-locking blocking means of independent spare parts purchasing, again can the overall online service life that extends controller after place in operation.
3. because self-locking blocking means repair time that the controller that causes changes of wearing and tearing can, by changing the form of stop device parts, shorten and change the repair time greatly.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further described, Fig. 1 is the sectional structure schematic diagram of the utility model controller upper cover plate, and Fig. 2 is the controller upper cover plate plan structure schematic diagram that Fig. 1 removes controller level.
Detailed description of the invention
A kind of improved controller self-locking stop configurations, as Fig. 1, shown in Fig. 2, comprise the dead bolt 3 arranging on controller level 2, dead bolt 3 matches with the self-locking blocking means arranging on controller upper cover plate 1, self-locking blocking means is two symmetrical upright right-angled triangle blocks 4, removable self-locking blocking means mounting hole is being set on controller upper cover plate 1, periphery is being set on mounting hole to recessed concave station, removable self-locking blocking means is installed on mounting hole, the structure of removable self-locking blocking means is that two symmetrical upright right-angled triangle blocks 4 are being set on dull and stereotyped 6, two right-angled triangle blocks 4 match with the dead bolt 3 on controller level 2, be arranged on flat board 6 its end faces on mounting hole concordant with the plate face of controller upper cover plate 1, dull and stereotyped 6 are fixed on the concave station of mounting hole by flathead screw 5.
