Description
Technical field
The present invention relates to a kind of elevator, particularly a kind of elevator machine holdout device.
Background technology
Along with the fast development in home lift market in recent years; Home lift life security guarantee to the maintainer in maintenance is obviously more and more important; For this reason; State General Administration for Quality Supervision and normalisation cuncil have issued GB/T 21739-2008 " home lift manufacturing and installation specification " in May, 2008; This standard has had clear and definite regulation to the top layer and the pit space of home lift, when repair and maintenance personnel's life security can not be guaranteed in the top layer and the pit space of household electrical ladder, needs to install mechanical holdout device and guarantee this survival space as accessory equipment.
Summary of the invention
The purpose of this invention is to provide a kind of home lift and use mechanical holdout device, make it easy to operate simple, and improved the safety of maintainer when getting into the hoistway operating maintenance, ensured maintainer's life security.
The objective of the invention is to realize like this: a kind of home lift is used mechanical holdout device, Yi Bian comprise the L type connecting panel that is fixed on the cage guide, the another side inboard of said connecting panel is installed with the flute profile base; The set inside of said base has the flute profile swing arm in opposite directions of notch and base notches; Hinged between said base and the swing arm through S. A., also be connected between said base and the swing arm through elastic mechanism, said elastic mechanism is installed in the top of S. A.; Said swing arm upper end is installed with energy disperser; The swing arm lower end is wedge shape, is installed with junction button on the swing arm inwall, and said junction button links to each other with the spanner that declutches of restriction swing arm turned position.
When the present invention works, when the staff need get into well pit or top maintenance, close the elevator power supply earlier; Make elevator out of service, and then unclamp the spanner that declutches that swing arm is rotated around S. A. under the storage elastic force effect of elastic mechanism; At this moment; The energy disperser that is fixed together with swing arm upper end rotates to blocked state along with swing arm is tilted simultaneously from normal condition, and the position that energy disperser is under the blocked state is the position of elevator upper pillar stand; Thereby play the purpose that stops elevator cab movement, guarantee the safe condition of space for maintenance; When maintenance finished, the staff was through the spanner pulling swing arm of declutching, and swing arm is rotated around S. A. under the effect of the spanner pulling force that declutches, and energy disperser is along with swing arm is got back to normal condition from blocked state simultaneously, and opening elevator power supply again makes the elevator normal operation; Beneficial effect of the present invention is: the present invention is switched between normal condition and blocked state through declutch spanner controller buffer and swing arm simultaneously; It is easy to operate simple; Connecting panel is fixed on the cage guide, and the captive joint relation between connecting panel, base, the swing arm has all been strengthened integrally-built stability; Thereby further improved the safety of maintainer when getting into the hoistway operating maintenance, ensured maintainer's life security.The present invention can be used in the home lift.
In order to improve the safety of maintainer when getting into hoistway work; Ensure maintainer's life security; The outside of said base is set with the limit switch of control elevator operation; Said chassis outer side also is provided with the switch that triggers the limit switch action and re-packs, and switch re-packs and is fixed on the end that S. A. stretches out base.Switch re-packs, and the action message of triggering limit switch feeds back to the elevator electric loop when rotating, thereby the control elevator quits work.
Can control elevator and quit work in order further to guarantee limit switch; Avoid in time to stop elevator work because of limit switch damages; Thereby limit switch is provided with two; And re-packing with respect to said switch is symmetrical set, and switch re-packs and can trigger two limit switch work simultaneously, and said limit switch all is fixed on the base through switch bracket.Further ensured maintainer's life security.
For the structural stability of reinforced company's fishplate bar, thereby improve integrally-built intensity and stability, said connecting panel is provided with reinforced rib.
As improvement of the present invention, said elastic mechanism is a retracing spring.Make it simple in structure, with low cost.
For ease at hoistway external control mode of operation of the present invention; Do not receive the restriction of position, said junction button links to each other through brake cable between the spanner with declutching, and the spanner that declutches is hingedly mounted on the adapter plate; Also be provided with the inhibiting device that limits the spanner position of declutching on the adapter plate; Said adapter plate is installed on the hoistway external wall, and the crust two ends of said brake cable are connected on said connecting panel and the said adapter plate, and the steel wire of brake cable is connected on the end and said junction button of the said spanner that declutches.Make that in the course of the work the action through the spanner pulling brake cable control swing arm of declutching when arriving assigned address, can keep the residing operating state of swing arm through inhibiting device.
Regulate the position that the spanner that declutches limits for ease, said inhibiting device is a bearing pin.
