The utility model solves the problem that the second protecting measure of the car-locking mechanism of the conventional machine-roomless lift is unstable. The car-locking mechanism comprises a retainer, a base and a safety switch fixed on the base, a bolt which is slidably connected with the base is arranged in the base, one end of the bolt is a locking end which can be inserted into the retainer, the other end of the bolt is a triggering end which triggers the safety switch to switch on and off, a bar-shaped handle is vertically arranged on the bolt between the locking end and the triggering end, and a locking structure is arranged between the lower end of the handle and the base. The car-locking mechanism can lock the handle, the power can be cut off even if the handle is unlocked, and thereby the utility model eliminates the defect that the instability of the car-locking mechanism causes the accidental motion of a car.
Description
Technical field
The utility model belongs to the elevator technology field, relates to a kind of car blocking device of car blocking device, particularly a kind of machine-roomless lift.
Background technology
Along with machine-roomless lift equipment in modern society application and further develop, the controlled of their safe operation and working service more and more comes into one's own.The car blocking device of tradition machine-roomless lift comprises the handle that a latch and control latch move, and this handle is positioned in the draw-in groove to be fixed.But, this fixed form effect of handle is undesirable, and this handle is laterally placed, rope of being constructed and cable tangle and take out of easily, thereby make handle break away from draw-in groove, cause latch to be in unconfined free state, in case the limiting bracket on latch and the guide rail breaks away from, can not limit moving of lift car, car will be in fall dangerous state.
When maintaining elevator and need utilize car roof as service platform, for overcoming above-mentioned contingent situation, common way is to have hung car with instruments such as iron cucurbits; Secondly, in the limiting bracket on the latch insertion cage guide of car blocking device, prevent second pipe protection of car accidental shifting with the conduct of car blocking device.Though the twice safety method is arranged, the second pipe protection measure makes this second pipe protection measure instability to have certain potential safety hazard owing to there not be consideration to prevent that accident from extracting the situation of latch.
The utility model content
The utility model is at above-mentioned defective, a kind of car blocking device of machine-roomless lift is provided, this car blocking device can lock handle, even also can power cut-off when handle goes out of lock state, eliminates because of the unstable situation that causes the car accidental shifting of car blocking device.
The utility model is realized by following technical proposal: a kind of car blocking device of machine-roomless lift, comprise limiting bracket, base and be fixed in safety switch on the base, in base, be provided with latch with the base sliding block joint, one end of latch is for being inserted into the keyed end in the limiting bracket, it is characterized in that, the other end of described latch is for touching the trigger end that safety switch opens and closes, on the latch between keyed end and the trigger end, be provided with the handle of bar shaped, described handle vertically is provided with, and is provided with latch-up structure between the lower end of handle and the base.
The utility model is fixed in limiting bracket on the cage guide in use, and base is fixed on the lift car.When not needing repairing, latch is withdrawn in the base by handle resets, handle is locked on the base by latch-up structure; When needing repairing, lift car is moved to the limiting bracket place, the unlocked structure drives latch by moving handle and is inserted in the limiting bracket the restriction of handle, by latch-up structure handle is being locked.Because handle is vertical setting, and between its lower end and the base latch-up structure is set, the rope of construction and cable can't tangle, and eliminate the situation that the handle accident loses restriction.
In the car blocking device of above-mentioned machine-roomless lift, described latch-up structure comprises nut that is fixed on the latch and the spacing hole that is arranged on the base, the upper end of handle is arranged in the nut and between the two by being threaded, the lower end of handle is plugged in the spacing hole when handle moves down, and the lower end of handle breaks away from spacing hole when moving on handle.Turning handle descends handle, and the lower end of handle is inserted in the spacing hole, and the top and bottom of handle all are positioned like this, can't move along the moving direction of latch.Otherwise turning handle rises handle, and the lower end of handle breaks away from spacing hole, and handle can be moved along the moving direction of latch.
In the car blocking device of above-mentioned machine-roomless lift, described trigger end is provided with and hits bow, this hits bow and comprises flat board and the flanging of upwards being turned up by dull and stereotyped side, described flanging is positioned at flat board one side near handle, roller contact when latch is inserted in the limiting bracket in the safety switch contacts with dull and stereotyped, and the roller contact in the time of in latch is withdrawn base fully in the safety switch contacts with above-mentioned flanging.In the time of in latch is withdrawn base fully, the roller contact rises along flanging and makes the safety switch closure, allows elevator main normally move; If be inserted in the limiting bracket or when not withdrawing in the base fully, hit the flat board of bow and push down the roller contact always, safety switch is in off-state, allows the elevator main operation of can not switching on.
In the car blocking device of above-mentioned machine-roomless lift, described spacing hole is two.One of them spacing hole is used for the state that dead bolt inserts limiting bracket, and another spacing hole is used for the state in the dead bolt withdrawal base.
In the car blocking device of above-mentioned machine-roomless lift, described base takes the shape of the letter U, and above-mentioned handle is arranged in the base.Handle is ensconced in the base, reduce the chance that rope contacts with handle.
In the car blocking device of above-mentioned machine-roomless lift, the lower end of described handle is provided with rubber pad.Make flexible contact between handle and the base by rubber pad.
In the car blocking device of above-mentioned machine-roomless lift, the latch of the both sides of described nut is provided with positioning plate.Limit the distance that latch moves by positioning plate.
In the car blocking device of above-mentioned machine-roomless lift, the side of described handle is a multi-prismatic surface.Except adopting multi-prismatic surface, also can adopt anti-skidding means such as decorative pattern are set in the handle side.
Compared with prior art, device of the present utility model vertically arranges handle, and with the latch-up structure lock handle that nut and spacing hole constitute, and makes this device at reset mode with mode of operation is all highly stable and safety.Device of the present utility model is under reset mode, the distance of hitting the flanging of bow and safety switch is very short, if because the artificial origin makes handle not insert spacing hole, in this case, in case latch outwards has short range to move, and will touch safety switch, make safety switch cut off the power supply of elevator main, elevator can't move, thereby avoids damaging elevator.
