This safety device passes through the elastic connection between the part, has accelerateed transmission efficiency, has reduced the fault rate. And the fixed mode of haulage rope has become swing joint, the installation and the dismantlement of follow -up railcar and haulage rope have been made things convenient for.
Description
Technical field
The utility model relates to a kind of elevator, particularly for the safety device in passageway lift.
Background technology
As patent No. CN200710071436.X, name is called a kind of patent of invention of relay type passageway lift,
Pedal is the load bearing component for carrying passenger, and personnel stand on pedal, then are moved by rail vehicle.And rail vehicle just needs an actuating device to drive.Draw gear disclosed in above-mentioned patent is electrical motor and reductor, and the fortune of motor control rail vehicle is stopped, and reductor is connected with rope dish by its output shaft, the steel wire rope traction track car that described rope reel is drawn.Once after steel wire rope fracture, rail vehicle will lose pulling force, thus there is the safety misadventure on landslide.So need to tackle this unforeseen circumstances and design a kind of safety and tackle device.
Utility model content
The purpose of this utility model is to provide the safety device that a kind of safety factor is high, driving efficiency is fast, fault rate is little.
Above-mentioned technical purpose of the present utility model is achieved by the following technical programs: a kind of safety device of passageway lift, comprise and be arranged at the rectangular and one end of square tooth bottom rail vehicle and be articulated and connected the swing arm on rail vehicle, the other end of described swing arm arranges hook, hauling rope is connected in described hook, described swing arm arranges the extension spring contrary with hauling rope force direction, described swing arm is after the same side near extension spring is arranged on hauling rope fracture, for buckle rectangular with square tooth, make the safety lever that rail vehicle is braked, one end of described safety lever is linked in described swing arm, the other end arranges Access Division of matching rectangular with square tooth.
Time hauling rope does not rupture, swing arm can be strained.Once hauling rope fracture, swing arm can tilt to safety lever direction under the effect of extension spring, and by the interlock of spring, swing arm orders about Access Division and the rectangular clamping of square tooth of safety lever one end, produces braking effect.Otherwise, may occur operator can from outside to rail vehicle at from bottom to top side's upwardly rail vehicle.Because the decline of rail vehicle is declined by self gravitation effect; when rail vehicle is promoted upward movement by external force; hauling rope will lose the application force to rail vehicle; in like manner swing arm also just loses the pulling force of hauling rope; that swing arm still can move to safety lever direction; thus the engaging driving safety lever rectangular with square tooth, realize safety protection function.
As preferably, be rotationally connected by turning cylinder and rail vehicle in the middle part of described safety lever.
As preferably, described extension spring is connected with rail vehicle by fixed link.
As preferably, one end that described swing arm arranges hook at it arranges location division, and it is a rectangular block that described location division comprises, and the side of rectangular block arranges the opening being used for swing arm motion.
As preferably, described swing arm is towards the other master cock arranged for monitoring swing arm position in side of hauling rope.If after hauling rope fracture, swing arm can move, and also just have left original position, and such master cock will sense, thus stops the operation of drive motor.
As preferably, this part is forced section to Access Division for described safety lever and turning cylinder point of connection, and the width of described forced section is greater than other parts of safety lever.
In sum, the utility model has following beneficial effect:
Safety device is connected by the elasticity between parts, accelerates driving efficiency, decreases fault rate.And the fixed form of hauling rope becomes flexible connection, facilitate the Assembly &Disassembly of subsequent rail car and hauling rope.
Accompanying drawing explanation
Fig. 1 is front schematic view of the present utility model;
Fig. 2 is the structural representation of swing arm;
Fig. 3 is the structural representation of safety lever.
In figure, 1-rail vehicle, 2-swing arm, 21-location division, 211-opening, 3-links up with, and 4-hauling rope, 5-extension spring, 51-fixed link, 6-safety lever, 61-spring, 62-turning cylinder, 63-Access Division, 64-forced section, 7-side's tooth is rectangular, 8-master cock.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Figure 1-3, a kind of safety device of passageway lift, comprise and be arranged at square tooth rectangular 7 bottom rail vehicle 1 and one end and be articulated and connected the swing arm 2 on rail vehicle 1, the other end of described swing arm 2 arranges hook 3, described hook 3 is directly flexibly connected hauling rope 4, described swing arm 2 arranges the extension spring 5 contrary with hauling rope 4 force direction, and described extension spring 5 is connected with rail vehicle 1 by fixed link 51.Described swing arm 2, after the same side near extension spring 5 is arranged on hauling rope 4 fracture, for 7 buckles rectangular with square tooth, makes the safety lever 6 that rail vehicle 1 is braked.As shown in Figure 3, described safety lever 6 is inverted L shape, is rotationally connected in the middle part of it by turning cylinder 62 and rail vehicle 1.One end of described safety lever 6 is connected with swing arm 2 by spring 61, and the other end arranges the Access Division 63 of matching with square tooth rectangular 7.Here the effect of spring 61 allows one end of safety lever 6 be connected with swing arm 2, time swing arm 2 moves, can be transferred on safety lever 6 by fast speed.So preferred version is that the side of safety lever 6 one end contacts with swing arm 2 here.And be move by directly contacting safety lever 6 when swing arm 2 motion, and non-fully is driven by spring 61.To Access Division 63, this part is forced section 64 to described safety lever 6 with turning cylinder 62 point of connection, and the width of described forced section 64 is greater than other parts of safety lever 6.After hauling rope 4 ruptures, Access Division 63 and square tooth rectangular 7 clamp, and the power of at this moment rail vehicle braking can be distributed on forced section 64, so forced section 64 needs, by increasing its width or thickness, to increase its intensity.
As illustrated in fig. 1 and 2, one end that described swing arm 2 arranges hook 3 at it arranges the location division 21 being fixed on rail vehicle 1, and it is a rectangular block that described location division 21 comprises, and the side of rectangular block arranges the opening 211 being used for swing arm 2 and moving.Described swing arm 2 is towards the other master cock 8 arranged for monitoring swing arm 2 position in side of hauling rope 4.After having had the location of location division 21, just can set the position on swing arm 2, thus be beneficial to the monitoring of master cock 8.Once after hauling rope 4 fracture, swing arm 2 moves, and master cock 8 will stop the operation of the drive motor of passageway lift immediately, also can give the alarm simultaneously.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; those skilled in the art can make to the present embodiment the amendment not having creative contribution as required after reading this specification sheets, as long as but be all subject to the protection of patent law in right of the present utility model.
