Abstract
The invention discloses an elevator with a safe inhaul cable device, which comprises a rack, a motor, an elevator and an electric control system and is characterized by further comprising the safe inhaul cable device, wherein the safe inhaul cable device is positioned on a platform on the top of the rack. When the elevator operates normally, a safe inhaul cable operates synchronously along with the elevator under the joint function of a retractor and a reset spring; when the elevator rapidly descends because the motor malfunctions, a steel wire rope ages and fractures, a speed measurement pendulum bob in the safe inhaul cable device automatically swings clockwise to drive a safe turning plate to cock and clamp a moving fastening ratchet wheel, so that the retractor stops rotating, at the moment, the safe inhaul cable replaces the steel wire rope to bear the elevator and enables the elevator to immediately stop high-speed descending, so that an accident is avoided.
Description
Technical field
The present invention relates to a kind of elevator, relate in particular to a kind of elevator with safety stay cable device.
Background technology
Existing elevator is mainly used in construction trade, is to be fixed on elevator by steel rope, and its running is to carry out controlling run by the motor of top.For ground goods and materials are transported to high-rise operation, conventionally adopt steel rope to fix, motor drives, complete motion process, but there is a drawback in this traditional mode of motion, because elevator often in the environment in exposing to the sun and rain, makes its part accelerated weathering, very easily make steel rope get rusty, aging, this is reducing its safety loading coefficient day by day, and in the time of device fails, such as motor is malfunctioning, wire cable ruptures etc. all can cause elevator fast-descending, and serious accident occurs.
In view of above-mentioned defect, be necessary to design in fact a kind of elevator with safety stay cable device.
Summary of the invention
Technical matters to be solved by this invention is: a kind of elevator with safety stay cable device is provided, solves elevator and occur that in routine duties the problem of safety misadventure occurs in landing at a high speed.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of elevator with safety stay cable device, comprise frame, motor, elevator and electric control system, and also comprise safety stay cable device, described safety stay cable device is positioned at frame top platform.
Further, also comprise outer cover, described outer cover is positioned at frame top platform, adopts and is screwed.
Further, also comprise two bearing holes, two described bearing holes are positioned at the front-back center of outer cover.
Further, also comprise zanjon ball bearing of main shaft, described zanjon ball bearing of main shaft is positioned at bearing hole, adopts interference fit.
Further, also comprise taking-up device, described taking-up device, between two zanjon ball bearing of main shafts, is synchronizeed and is rotated with zanjon ball bearing of main shaft.
Further, also comprise safe drag-line, described safe drag-line is positioned on taking-up device, and employing connects firmly.
Further, also comprise stop gear, described stop gear is positioned at taking-up device both sides, and stop gear outside is provided with circular groove, and stop gear adopts keyway to be connected with taking-up device.
Further, also comprise retracing spring, described retracing spring is positioned at the circular groove in stop gear outside, and the two ends of retracing spring are welded on respectively on stop gear and outer container.
Further, also comprise safety reverse turning bed, described safety reverse turning bed is positioned at outer container bottom, adopts chain connection.
Further, also comprise the pendulum that tests the speed, the described pendulum that tests the speed is positioned at safety reverse turning bed below, adopts welding manner to be connected on safety reverse turning bed.
Compared with prior art, with the elevator of safety stay cable device, in the time of equipment normal operation, safe drag-line under the common effect of taking-up device and retracing spring along with elevator synchronous working, when occurring, motor is malfunctioning, when the aging fracture of steel rope etc. causes the situation of the very fast decline of elevator, the pendulum that tests the speed in safety stay cable device can swing by automatic cw, drive safety reverse turning bed perk, block the stop gear in motion, thereby stop taking-up device rotation, now safe drag-line replacement steel rope carries out load-bearing to elevator, make elevator can stop immediately declining at a high speed, avoid the generation of safety misadventure.

Detailed description of the invention
Hereinafter, set forth multiple specific detail, to the thorough understanding of the concept to forming described embodiment basis is provided.But to one skilled in the art, described embodiment can put into practice some or all in these specific detail in the case of not having obviously.In other cases, do not specifically describe well-known treatment step.
As Fig. 1, Fig. 2, shown in Fig. 3, comprise frame 1, elevator 2, motor 3, electric control system 4, safety stay cable device 5, outer cover 501, zanjon ball bearing of main shaft 502, taking-up device 503, safe drag-line 504, stop gear 505, retracing spring 506, safety reverse turning bed 507, pendulum 508 tests the speed, described safety stay cable device 5 is positioned on the top platform of frame 1, described outer cover 501 is positioned at frame 1 top platform, adopt and be screwed, described zanjon ball bearing of main shaft 502 is positioned at bearing hole, adopt interference fit to knock hand-hole, described taking-up device 503 is between two zanjon ball bearing of main shafts 502, synchronize rotation with zanjon ball bearing of main shaft 502, described safe drag-line 504 is positioned on taking-up device 503, employing standard lock knot mode is fixed on taking-up device 503, described stop gear 505 is positioned at taking-up device 503 both sides, stop gear 505 outsides are provided with circular groove, stop gear 505 adopts keyway to be connected with taking-up device 503, described retracing spring 506 is positioned at the circular groove in stop gear 505 outsides, the two ends of retracing spring 506 are welded on respectively on stop gear 505 and outer container 501, described safety reverse turning bed 507 is positioned at outer container bottom, adopt chain connection, the described pendulum 508 that tests the speed is positioned at safety reverse turning bed 507 belows, adopt welding manner to be connected on safety reverse turning bed, when work, elevator 2 is in the time of normal decline, drive safe drag-line 504 and taking-up device 503 synchronously to rotate, produced the tension force of the retracing spring 506 in stop gear 505 grooves simultaneously, elevator 2 is in the time of normal rising, retracing spring 506 starts resilience, drive the reverse choosing dress of stop gear 505, tighten up safe drag-line 504, when malfunctioning when there is motor 3, when the aging fracture of steel rope etc. causes the situation of elevator 2 very fast declines, the pendulum 508 that tests the speed in safety stay cable device 5 can swing by automatic cw, drive safety reverse turning bed 507 perks, block the stop gear 505 in motion, thereby stopping taking-up device 503 rotates, now safe drag-line 504 replaces steel rope elevator 2 is carried out to load-bearing, make elevator 2 can stop immediately declining at a high speed, ensure safety.
