Description
Technical field
The utility model relates to a kind of elevator fixed support, particularly a kind of cab guide rail locking device.
Background technology
China's home lift industry develop rapidly in recent years, but at hoistway headroom height and pit depth, can not meet under the condition of installation dimensions, mostly adopt the mode of steel pipe top to guarantee service clearance.But such space makes the personnel of actual maintenance and steel pipe in different locus, can not control steel pipe.Once steel pipe, by intentional or unintentional movement, will likely produce serious consequence.
Technical scheme
For problems of the prior art, the purpose of this utility model be to provide a kind of safe and reliable, the personnel that no matter maintain are at well pit or at hoistway top layer, maintain the cab guide rail locking device that can operate, control, not be subject to external factor to affect.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of cab guide rail locking device, comprise jam plate, lock pin, locking pin seat, backing pin, switch bracket, switch, sedan-chair frame straight beam, cab guide rail and guide rail folder, described car guide rail is connected with sedan-chair frame straight beam falcon groove, described cab guide rail is provided with jam plate and guide rail folder, described sedan-chair frame straight beam is fixed with locking pin seat, in described locking pin seat, be nested with backing pin, between described backing pin and guide rail folder, switch is installed, described switch is fixed by switch bracket, described lock pin and guide rail folder free-running fit.Described switch is automatic reset switch.
Adopt after technique scheme, the utlity model has following beneficial effect: 1. guide rail locking device of the present utility model, safe and reliable, under the condition of maintainer in the non-security distance of hoistway, can provide safer protection; And simple in structure, processing and fabricating is convenient, cost is low, is beneficial to popularization.2. guide rail locking device of the present utility model, easy for installation, is applicable to multiple elevator selection and adopts.

In figure: 1 cab guide rail; 2 jam plates; 3 sedan-chair frame straight beams; 4 locking pin seat; 5 backing pins; 6 guide rail folders; 7 switches; 8 switch brackets; 9 lock pins.
The specific embodiment
According to Figure of description and specific embodiment, the utility model is further explained below.
As Fig. 1, shown in Fig. 3, a kind of cab guide rail locking device, comprise jam plate 2, lock pin 9, locking pin seat 4, backing pin 5, switch bracket 8, switch 7, sedan-chair frame straight beam 3, cab guide rail 1 and guide rail folder 6, described car guide rail 1 is connected with sedan-chair frame straight beam 3 falcon grooves, described cab guide rail 1 is provided with jam plate 2 and guide rail folder 6, as shown in Figure 2, described sedan-chair frame straight beam 3 is fixed with locking pin seat 4, in described locking pin seat 4, be nested with backing pin 5, as shown in Figure 4, between described backing pin 5 and guide rail folder 6, switch 7 is installed, as shown in Figure 5, described switch 7 is fixing by switch bracket 8, described lock pin 9 presss from both sides 6 free-running fits with guide rail.Described switch 7 is automatic reset switch.
When maintainer's work area is during in well headroom, the two cover guide rails locks on sedan-chair frame top are inserted in the hole of jam plates 2, cab is fixed, prevent that cab is by mistake mobile up and down, utilize cab top as maintenance platform operation; When maintainer's work area is during in hoistway bottom, two cover guide rails locks of sedan-chair frame bottom are inserted in the hole of jam plates, cab is fixed, prevent that cab is by mistake mobile downwards, produce personal injury.Every cover guide rail lock is all with a safety switch 7, and when guide rail is locked in control position, switch 7 disconnects the safety return circuit of elevators, guarantees other the non-personnel's of being transferred to civilian work error starting elevators.Play to greatest extent the effect of safety component.
