Abstract
The invention discloses a mechanical stop device for an elevator. The mechanical stop device comprises a round pipe (1). A telescopic rod (2) is connected to the upper side of the round pipe (1). A rubber support pad (3) is arranged at the top of the telescopic rod (2). A bolt component (4) is arranged at the joint between the round pipe (1) and the telescopic rod (2). The bottom of the round pipe (1) is connected to a base (6) through a camshaft (5). A cam (7) is arranged on the camshaft (5). A normally-closed UTK switch (8) and a normally-open UKT switch (11) are arranged on the left side and the right side of the cam (7) respectively. The telescopic rod and the bolt component are used for adjusting device length, so that space used for placement of a car ceiling or bottom pit can be guaranteed when the device is in a non-operating state, and the working height of the device can be also guaranteed. Expansion bolts are mounted in the bottom pit or common bolts are mounted on the car ceiling, and accordingly, universalization can be realized. Electric linkage protection is realized through the cam, the normally-closed UTK switch and the normally-open UKT switch, and safety and reliability of the stop device are guaranteed.
Description
?
Technical field
the present invention relates to a kind of elevator holdout device, particularly a kind of elevator machine holdout device.
Background technology
present home lift is much arranged in villa, and villa often asks most appearance looks elegant to cause the headroom height of elevator hoistways and pit depth all smaller, under this this special condition, in order to meet the safety inspection space of top layer and pit, need a kind of mechanical stopping device.Existing mechanical stopping device general structure more complicated and be divided into two kinds: one is contained in pit, and one is contained in sedan-chair top.A mechanical stopping device being contained in pit, just can not be contained in sedan-chair top; A mechanical stopping device being contained in sedan-chair top, just can not be contained in pit, commonality is not strong.Therefore, present elevator machine holdout device also exists the problem that structure is more complicated, production and processing is not too convenient and commonality is not strong.
Summary of the invention
the object of the invention is to, a kind of elevator machine holdout device is provided.The present invention has the advantage that structure is simple, be convenient to production and highly versatile.
technical scheme of the present invention: a kind of elevator machine holdout device, comprises pipe, be connected with expansion link above pipe, and expansion link top is provided with rubber mount pad; Pipe and expansion link junction are provided with latch assembly, connect base bottom pipe by camshaft; Camshaft is provided with cam, is provided with normally closed UKT switch on the left of cam, is provided with on the right side of cam and often drives UKT switch; Described normally closed UKT switch and Chang Kai UKT switch are all fixedly connected on base by screw.
in aforesaid elevator machine holdout device, described base is provided with baffle plate, and base is also connected with pipe by spring.
compared with prior art, present invention improves over elevator machine holdout device structure, adopt expansion link and latch assembly to carry out control apparatus length, can to ensure that when off working state sedan-chair top or pit have living space placement, also can ensure the operating altitude of this device.Meanwhile, be arranged in pit or by plain bolt by expansion bolt and be arranged on sedan-chair top, realize universalization.The present invention also realizes, from the current mode of operation of judgment means electrically, realizing electric-linked protection, guaranteeing that holdout device is safe and reliable by cam, normally closed UKT switch and Chang Kai UKT switch.Therefore, the present invention have structure simple, be convenient to produce, highly versatile and safe and reliable advantage.
Accompanying drawing explanation
fig. 1 is the structural representation of mode of operation of the present invention;
fig. 2 is partial enlarged drawing of the present invention;
fig. 3 is the front view of off working state of the present invention;
fig. 4 is the birds-eye view of off working state of the present invention.
being labeled as in accompanying drawing: 1-pipe, 2-expansion link, 3-rubber mount pad, 4-latch assembly, 5-camshaft, 6-base, 7-cam, the normally closed UKT switch of 8-, 9-baffle plate, 10-spring, 11-often drives UKT switch.
Detailed description of the invention
below in conjunction with drawings and Examples, the present invention is further illustrated, but not as the foundation limited the present invention.
embodiment.A kind of elevator machine holdout device, form as shown in Figure 1,2,3, 4, comprise pipe 1, be connected with expansion link 2 above pipe 1, expansion link 2 top is provided with rubber mount pad 3; Pipe 1 and expansion link 2 junction are provided with latch assembly 4, connect base 6 bottom pipe 1 by camshaft 5; Camshaft 5 is provided with cam 7, is provided with normally closed UKT switch 8 on the left of cam 7, is provided with on the right side of cam 7 and often drives UKT switch 11; Described normally closed UKT switch 8 and Chang Kai UKT switch 11 are all fixedly connected on base 6 by screw.
described base 6 is provided with baffle plate 9, and base 6 is also connected with pipe 1 by spring 10.Described pipe 1 can rotate by respect thereto 6, and cam 7 rotates together along with pipe 1.
the present invention is by camshaft 5 and spring 10 connecting circular tube 1 and base 6, and pipe 1 can rotate around camshaft 5, and the cam 7 on camshaft 5 can rotate together along with pipe 1, thus makes to be arranged on the normally closed UKT switch 8 on base 6 and Chang Kai UKT switch motion.By the latch assembly 4 on pipe 1, the length of expansion link 2 of the present invention can be regulated.On expansion link 2, be threaded connection rubber mount pad 3, the energy produced because of car accidental impact can have been absorbed, ensured not damage elevator.Base 6 is provided with 4 fixed orifices, is arranged in pit or by plain bolt by expansion bolt and is arranged on sedan-chair top, realize universalization.
during mode of operation, as shown in Figure 1, 2.Base 6 has the baffle plate 9 of a block welding, and when being in endways state, spring 10 is stressed, and the direction of pipe 1 toward baffle plate 9 is pulled, thus ensures the stability of pipe 1.Cam 7 rotates with pipe 1, and cam 7 unclamps often drives UKT switch 11; When turning to mode of operation, cam 7 makes the action of normally closed UKT switch 8, thus can judge that this device is in running order on electrically, realizes electric-linked protection and has duplicate protection effect.
during off working state, as shown in Figure 3,4.Pack up expansion link 2, rotate pipe 1, band moving cam 7 rotates, and cam 7 unclamps normally closed UKT switch 8; When turning to off working state, cam 7 makes often to open UKT switch 11 action, makes it to be judged as off working state on electrically.
