Description
Technical field
The utility model belongs to the elevator technology field, is specifically related to the manual locking device that a kind of elevator uses in maintenance or fault correction.
Background technology
Elevator is the necessary equipment that tier building is taken advantage of people or transporting cargo, in order to guarantee lift running safety, need to regularly safeguard elevator as maintenance platform and overhaul by car, when safeguarding and overhaul, in order to guarantee staff's safety, at first need car stably is fixed on the guide rail, thereby guarantee that the staff keeps in repair having under the prerequisite of safety control.
(number of patent application is 201220298946.7 to Chinese patent, Granted publication number is CN202609722) a kind of machine-roomless lift maintenance latching device disclosed, guarantee the stable of car by the locating plate that the latch insertion that will be fixed on the straight beam is fixed on the guide rail, but because latch plate and handle switch cumbersome between off working state and state, and when fixing car (mode of operation), it is fixed orifice that latch plate only has an attachment point at car, so that the stressed burden of latch plate is very large, and always want manual-alignment switch contact and groove during power cut-off, extremely inconvenient.
Summary of the invention
For above shortcomings in the prior art, the utility model provides a kind of firm performance high for overhauling elevator, and outage is convenient, thereby improves the manual locking device of elevator safety effect.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is as follows:
A kind of elevator hand latching device, comprise the locating plate that is fixed on the cage guide rear side and be fixed on the lock bracket that car is put the beams in place, locating plate is provided with jack, described lock bracket is provided with the lock shaft that can cross lock bracket, jack coupling on this lock shaft and the locating plate, described lock shaft is provided with vertical lock shaft and fixing handle, at least two fixed orifice couplings on this handle and the lock bracket.
Adopt the utility model of technique scheme, work in the following way: when elevator needs repairing, at first take out the handle that inserts in the locating plate far-end fixed orifice, then lock shaft is pushed away inward so that lock shaft is inserted in the jack on the locating plate, again handle is inserted in the fixed orifice of locating plate near-end and fixes lock shaft, by the connection between locating plate, lock shaft, lock bracket and the upper beam car is fixed on the cage guide at last.
Preferably, be positioned on the lock shaft of lock bracket and be provided with positioning plate by the locating plate end, this positioning plate leaves clearance when handle inserts the fixed orifice nearest by locating plate and between the lock bracket.This positioning plate is in order to prevent that lock shaft from inserting the excessive lock shaft that causes of locating plate and being not easy to extract.
Preferably, have groove by the locating plate far-end on the described lock shaft, lock bracket is fixed with switch seat by prolonging outside the locating plate far-end, and switch seat is provided with switch contact, and this switch contact can place in the groove.When off working state, switch contact is positioned at groove, this moment source switch for opening, when needs keep in repair, lock shaft is pushed inward, switch contact is because being squeezed, so that the elevator power cut-off, has protected staff's safety.
More preferably, described lock shaft is square strip, and groove is the trapezoidal groove that lock shaft propelling movement and removing direction are equipped with the inclined-plane, and switch contact is positioning bead.The convenient groove that arranges thereon of square lock shaft, and the inclined-plane setting by the groove both sides and have the switch contact of positioning bead more to be conducive to switch contact to withdraw from groove, close the elevator power supply.
Compared with prior art, the firm performance that the utility model can improve between car and the cage guide is better, and outage is convenient, safety that can the safeguard work personnel.
Description of drawings
Fig. 1 is structural representation of the present utility model (off working state);
Fig. 2 is working state schematic representation of the present utility model.
The specific embodiment
In order to make those skilled in the art understand better the utility model, below in conjunction with drawings and Examples technical solutions of the utility model are further specified.
As depicted in figs. 1 and 2, a kind of elevator hand latching device, comprise the locating plate 2 that is fixed on cage guide 1 rear side and the lock bracket 4 that is fixed on car upper beam 3, locating plate is provided with jack 11, described lock bracket 4 is provided with the lock shaft 5 that can cross lock bracket 4, jack 11 couplings on this lock shaft 5 and the locating plate 2, the handle 6 that described lock shaft 5 is provided with vertical lock shaft 5 and is bolted, two fixed orifices 71 on this handle 6 and the lock bracket 4,72 couplings, fixed orifice 71 makes things convenient for latching device to fix lock shaft 5 under off working state, fixed orifice 72 convenient car and the locatings plate 2 fixed down in working order.
Be positioned on the lock shaft 5 of lock bracket 4 and be provided with positioning plate 8 by locating plate 2 ends, to prevent that lock shaft 5 from inserting the locating plate 2 excessive lock shafts 5 that cause and being not easy to extract, therefore when lock shaft 5 inserts locating plate 2, lock bracket 4 left sides should also have the lock shaft 5 of definite part to extend out conveniently to choose, positioning plate 8 leaves clearance when handle 6 inserts fixed orifice 72 and between the lock bracket 4, this can make propelling movement that the staff knows lock shaft 5 on earth, handle 6 can be inserted fixed orifices 72 and suffer.Have groove 12 by locating plate 2 far-ends on the lock shaft 5, this groove 12 is equipped with the trapezoidal groove on inclined-plane for lock shaft 5 propelling movements and removing direction, lock bracket 4 is fixed with the switch seat 9 that extends out by the locating plate 2 far-ends outside, switch seat 9 is provided with the switch contact 10 that can control the elevator power supply opening or close, and this switch contact 10 is adopted as positioning bead and is conducive to switch contact 10 and withdraws from and PTO Power Take Off along groove 12 inclined-planes.
The principle of work of this device under the brief description: when off working state, switch contact 10 is positioned at groove 12, this moment, power supply was in unlatching, handle 6 is fixed in the fixed orifice 71, lock shaft 5 does not insert in the jack 11 of locating plate 2 yet, when needs keep in repair, at first take out the handle 6 that inserts fixed orifice 71, then lock shaft 5 is pushed away inward so that lock shaft 5 is inserted in the jack 11 on the locating plate 2, at this moment switch contact 10 withdraws from groove 12 and is squeezed, thereby close the elevator power supply, guarantee staff's safety.Because the effect of positioning plate 8 just can stop to push after lock shaft 5 enters jack 11 certain distances, again handle 6 is inserted in the fixed orifice 72 and also fixes, and at last car is fixed on the cage guide 1.
Thereby the utility model is captiveed joint with the multiple spot between lift crosshead, the locating plate by lock bracket and is improved firm performance between car and the cage guide, and closes the elevator power supply when lock shaft pushes, further safeguard work personnel's safety.
The above elevator hand latching device that the utility model is provided is described in detail.The explanation of specific embodiment just is used for helping to understand method of the present utility model and core concept thereof.Should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also fall in the protection domain of the utility model claim.
