Description
Technical field
The present invention relates to a kind of lift appliance, particularly relate to a kind of elevator without machine room.
Background technology
Lift appliance has generally all disposed the parts that prevent the elevator overspeed operation, comprises the action component that detects elevator overspeed status detection parts and elevator is implemented deceleration.The parts that detect the elevator overspeed state generally all adopt velocity limiter, and its accessory is velocity limiter cable and tightener of cable.The velocity limiter cable links to each other with car, and the speed of cage operation is delivered on the velocity limiter, and tightener of cable is used for preventing that cable from rocking when elevator moves, and collision hoistway inner component perhaps causes velocity limiter or other associated components misoperation.
The velocity limiter of existing lift appliance and tightener of cable thereof all are configured in a side of guide rail (car guide rail or counterweight guide rail), with pivotally attached lever or independently its motion of rail guidance.In machine-roomless lift, the machine-roomless lift of small dimension especially, the car area is very little, and the parts in guide rail side and the hoist trunk or the distance of lifting channel wall are very little, adopt such layout just very difficult.The general-duty processing mode is, elevator adopts the structure of Backpack type, and car guide rail is arranged in the hoist trunk rear portion, a side of car, and car guide rail can enlarge markedly from the distance of hoist trunk front side, thereby can arrange velocity limiter and tightener of cable thereof easily.
But there is the problem in some essential structures in the Backpack type elevator, and for example, it is very big that car is led boots load, thereby generally must adopt to roll and lead boots, and cost is higher; After elevator did not move (as in the night) for a long time, rolling was led boots and is contacted the distortion that stressed outer layer rubber can produce the short time with guide rail, and elevator comfort when just bringing into operation can obviously descend.Other problem also has, and the stressed change of guide rail is big, thereby needs to adopt the guide rail of big specification, or the like.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of lift appliance, and it can guarantee that the eccentric force of leading on boots and the guide rail is little, simplifies the guide frame of velocity limiter tightener of cable simultaneously, cost-cutting.
For solving the problems of the technologies described above, lift appliance of the present invention comprises car, the actuating device of drive pulley is installed, counterweight or tightener of cable, the cable that connects car and counterweight or tightener of cable, the velocity limiter of monitoring car speed, transmit the velocity limiter cable of car movement, the velocity limiter tightener of cable, the counterweight guide rail that car guide rail that the guiding car moves and guiding counterweight or tightener of cable move holds car, actuating device, counterweight or tightener of cable, the hoist trunk of cable, wherein, the velocity limiter tightener of cable is arranged in the lower end of hoist trunk, is guiding rail with car guide rail or counterweight guide rail.
Adopt lift appliance of the present invention, elevator for small dimension, also can be arranged in the car center to car guide rail, the eccentric force that assurance is led on boots and the guide rail is little, can adopt and lead boots and the very high ride comfort sense of guide rail acquisition cheaply, simplify the guide frame of velocity limiter tightener of cable simultaneously, reduce cost, and make the mechanical system structure of elevator arrange freedom more, reduce the civil engineering size.

Fig. 1 is the block diagram of first kind of embodiment of lift appliance of the present invention in hoist trunk;
Fig. 2 is the block diagram of the another kind of embodiment of lift appliance of the present invention in hoist trunk;
Fig. 3 is a kind of representative type floor plan scheme of lift appliance of the present invention in hoist trunk;
Fig. 4 is the birds-eye view of velocity limiter tightener of cable in hoist trunk in the lift appliance of the present invention.
The specific embodiment
As shown in Figure 1, in first kind of embodiment of the present invention, described lift appliance comprises car 1, actuating device 2.Drive pulley 3 is installed on actuating device 2.Also comprise counterweight or tightener of cable 4, the cable 5 that connects car 1 and counterweight or tightener of cable 4, the velocity limiter 6 of monitoring car 1 speed, transmit the velocity limiter cable 7 of car 1 motion, velocity limiter tightener of cable 8, the car guide rail 9a that moves of guiding car 1, the counterweight guide rail 9b that guiding counterweight or tightener of cable 4 move holds the hoist trunk 10 of car 1, actuating device 2, counterweight or tightener of cable 4, cable 5.
Elevator drive and operation carrying part are basic identical with conventional lift, velocity limiter 6 is installed in the side of the upper end of car guide rail 9a by its side, velocity limiter tightener of cable 8 is installed in the car guide rail 9a side of hoist trunk bottom, and be its guiding rail with car guide rail 9a, the vertical component of velocity limiter cable 7 is distributed in the both sides of car guide rail 9a.
Another embodiment of the invention as shown in Figure 2, velocity limiter 6 is installed in by its bottom surface on the mount pad on guide rail 9a top, the mounting means of other parts is identical with first kind of embodiment shown in Figure 1.
Referring to Fig. 3, in a kind of Typical Planar of the present invention is arranged, the line of centers of diversion sheave 11 is parallel to each other at the bottom of the line of centers of car guide rail 9a and two sedan-chairs, the line of centers of diversion sheave 11 passes through the center of gravity of car 1 substantially at the bottom of two sedan-chairs, car 1 unbalance loading is minimum, thereby the stressed improvement of associated components, the ride comfort sense improves.The rear side of car guide rail 9a all is distributed with cable 5 (in conjunction with Fig. 1,2), and the front side is nearer from hoist trunk 10 walls and car door machine, so front and back position all can't be arranged velocity limiter 6 and velocity limiter tightener of cable 8.Velocity limiter 6 relies on its side to be clamped on the car guide rail 9a.In conjunction with shown in Figure 4, in hoist trunk 10 bottoms, the side of velocity limiter tightener of cable 8 has a guide frame, leads on car guide rail 9a or counterweight guide rail 9b two sides.
Know those skilled in the art as can be known, embodiments of the present invention are not limited to foregoing, can be installed in velocity limiter 6 on the erecting frame on hoist trunk 10 tops as machine-roomless lift, organic machine room-free elevator can be fixed on velocity limiter 6 in the machine room, utilizes car guide rail 9a or counterweight guide rail 9b guiding equally.And for example, in particular cases, velocity limiter cable 7 needn't be distributed in the both sides of guide rail, can have at least a vertical component to be positioned at the back side of guide rail, and velocity limiter tightener of cable 8 can this guide rail be a guiding rail still.
Generally, on the velocity limiter tightener of cable 8 guide groove is arranged, form the guiding relation in order to the side with car guide rail 9a or counterweight guide rail 9b bottom, velocity limiter cable 7 vertical components are distributed in the both sides at car guide rail center.The velocity limiter 6 of organic machine room-free elevator can be arranged in the machine room, and from horizontal surface, velocity limiter 6 is arranged in the top at this car guide rail back side; The velocity limiter 6 of machine-roomless lift can be directly installed on the top of this car guide rail, thereby saves the arrangement space in the hoist trunk 10, especially can be used for solving the interior arrangements of components difficulty of hoist trunk of small dimension machine-roomless lift.
