Abstract
The utility model discloses a locking device for a steel cable track lifting machine, which comprises a steel cable, a lifting platform, a motor and a hoisting rope. The utility model is characterized in that a locking device is arranged on the steel cable, and a rotating shaft is arranged in a casing of the device; both ends of the rotating shaft are fixed with a swinging arm which is at the angle of 180 DEG; a lower hanging rope is connected to a ring on the rotating shaft and the swinging arm and is connected with a pull rope of the lifting platform; an upper hanging rope is connected to the ring on the rotating shaft and the swinging arm and is connected with the lifting rope; a spring is connected between the casing and the swinging arm which is connected with the upper and the lower hanging ropes; two steel cable tracks are respectively penetrated in radial holes on the rotating shafts in two locking devices. When the accident of platform roof fall or rope break, etc., happens in a lifting machine and the lifting platform freely falls along a track of the steel cable, the locking device can automatically lock the lifting platform on the track of the steel cable to prevent the accident from happening. The locking device can be used on a lifting rope of a working platform on which an outer wall of a building is coated.
Description
(1) technical field: the utility model belongs to a kind of lifting means, particularly the locking device of cable wire guide rail elevator.
(2) background technology, building operations need be transported constructional materials to the high-altitude, mainly relies on tower crane, but as a kind of cable wire guide rail elevator of auxiliary equipment, is indispensable construction equipment.Cable wire guide rail elevator is in promoting material and personnel, because operating personnel's carelessness and equipment breaks down, cause the platform roof fall and break article, even the major accident of casualties happens occasionally.
(3) summary of the invention: the utility model technical issues that need to address provide a kind of safety device of cable wire guide rail elevator, when the lifting platform roof fall takes place, platform is locked on the cable wire and can throw.The technical solution of the utility model is, the locking device of cable wire guide rail elevator, it includes cable wire, lifting platform, motor and lift rope, it is characterized in that: be located at locking device on the cable wire and include rotating shaft and be rotatably assorted in the hole of housing two side, rotating shaft is provided with radial hole, the two ends of rotating shaft are provided with the swing arm that is mutually 180 degree, be connected with a spring between one swing arm and the housing sidewall, the two ends of following lanyard are connected with ring in the rotating shaft with the swing arm that is provided with spring respectively, last lanyard two ends are connected with the rotating shaft ring with above-mentioned swing arm respectively, following lanyard is connected with the stay cord of lifting platform, the two ends of lanyard are connected with the hoisting rope of last lanyard and hoist engine respectively, and the cable wire guide rail is through in the interior rotating shaft radial hole of two locking devices.The utility model accident such as platform roof fall occurring owing to designed a kind of locking device, and platform is during along the free-falling of cable wire guide rail, and locking device can be locked in lifting platform on the cable wire guide rail automatically, and can not break article and casualty's accident.The tight device of this rope can also be used on the halliard of working platform of external wall brushing operation.
(4) description of drawings; Fig. 1 is a structural representation of the present utility model; Fig. 2 is the locking device structure schematic diagram.Among the figure, 1. 4. times lanyards of lifting platform 2. guide rail rings, 3. stay cords 5. encircle lanyard 9. lanyards 10. hoisting ropes 11. cable wire guide rails 12. swing arms 13. rotating shafts 14. regulating handles on 6. housings, 7. springs 8.
(5) specific embodiment: the utility model includes and is located at two locking devices on the cable wire guide rail, this locking device has a rotating shaft 13 to be rotatably assorted in the cinclides of the both sides of housing 6, the two ends of rotating shaft are fixed with the swing arm 12 that is mutually 180 degree respectively, the threaded rod that is provided with axial thread hole and regulating handle 14 in the turning cylinder of radial hole one side matches, the two ends of spring 7 are connected with the lower wall of swing arm 12 and housing respectively, the two ends of following lanyard 4 are connected with swing arm with ring 5 respectively, stay cord 3 on lifting platform 1 two ends is connected with following lanyard 4 on two locking devices respectively, also be connected with lanyard 8 in the swing arm that following stay cord is connected with encircling, the hoisting rope 10 that is dragged by motor connects with the lanyard 9 that two ends are connected with last lanyard.Article two, cable wire guide rail 11 is through at respectively in the rotating shaft radial hole and the guide rail ring 2 on the lifting platform of two locking devices, and its amount end is fixed with ground and top of building respectively.The tight device of this rope can also be used on the halliard of working platform of external wall brushing operation.
Safe locking principle of the present utility model is, when elevator makes hoisting rope 10 fractures cause lifting platform when the cable wire guide rail falls in that roof fall promote to take place, owing to do not have tension on the last lanyard, swing arm is understood under the effect of spring and weight body from turning to down, the cable wire guide rail is a S shape in shaft hole, because rope diameter is greater than the gap between rotating shaft and the housing wall, the gravity of platform is locked in platform on the cable wire guide rail.In addition, as man-hour is arranged on the platform, personnel also can handle regulating handle rapidly, and cable wire is pinned, and play dual fail-safe.
