Abstract
The utility model discloses a device for detecting falling off of a steel wire rope. The device for detecting the falling off of the steel wire rope comprises an off-tracking sensor and a rope catching device, wherein the off-tracking sensor is fixedly arranged on an end face of the rope catching device, and a swing rod is hinged to the off-tracking sensor through a pin shaft. The off-tracking sensor is arranged below the steel wire rope and used for detecting the working state of the steel wire rope. The rope catching device is arranged between the swing rod and the steel wire rope and fixedly arranged on a fixed shaft of a rope pulley, the rope catching device is used for preventing the steel wire rope from falling below the rope pulley, and the outer end of the rope catching device is bent upwards. The device for detecting the falling off of the steel wire rope can be used for detecting the situation of the falling off of the steel wire rope and preventing the steel wire rope from continually falling off, and safety of workers and equipment is guaranteed.
Description
Technical field
The utility model relates to the fender guard after steel rope that a kind of cableway transport field uses falls rope, a kind of specifically steel rope monitoring device that falls to restrict.
Background technology
Mining built on stilts manned ropeway is the preferred unit that transports personnel under the coal mine, and it has solved the problem that the long distance in down-hole, big sag are transported personnel in conjunction with the characteristics of coal mine roadway, has characteristics such as efficient, safe, easy to operate, that maintenance is little.The principle of work of cableway mainly is to rotate by the drive wheel that motor drives is connected on the reductor, adopts built on stilts rope traction carrying, and what steel rope moved just supports by rope sheave on the way.In the operational process of cableway, because steel rope whipping or swing can take place when stressed, cause steel rope to drop from rope sheave easily, thus accidents caused.
For preventing the generation of safety misadventure, the protection steel rope does not drop from rope sheave easily, and the measure of adopting at present mainly contains electric protection and this dual mode of mechanical protection.Electric protection generally is to use misalignment sensor; when steel rope drops, can touch the swing arm on the misalignment sensor, after in a single day misalignment sensor senses the action of swing arm, can pass to control desk to signal; under the control of control desk, realize the transportation device shutdown, to try to avert accidents.But this electric protection continues to drop owing to not stoping steel rope to stop; when the steel rope by gravity continues to drop after breaking away from swing arm; swing arm can restore balance again; and might not have fundamentally trouble-shooting this moment; but misalignment sensor is owing to the action of having responded to less than swing arm; can not be passed to control desk to the signal that steel rope has dropped yet; can restart facility under unwitting situation the staff of control desk, so just cause danger easily.Continue to drop though mechanical protection can prevent steel rope, can not allow control desk experience to drop the signal control transportation device to be shut down, equally also have potential safety hazard.
The utility model content
The utility model technical issues that need to address provide a kind of steel rope monitoring device that falls to restrict, and can monitor falling the rope situation and stoping steel rope to continue to drop of steel rope, get rid of potential safety hazard, guarantee the safety of staff and equipment.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is:
The steel rope monitoring device that falls to restrict, comprise and be arranged on the misalignment sensor that the steel rope below is used to monitor the steel rope mode of operation, misalignment sensor comprises by the bearing pin pivotally attached and is used to monitor the swing arm whether steel rope drops, also comprise being fixedly installed on by support being used on the rope sheave anchor shaft to stop that steel rope drops to the rope sheave below catches the rope device, described swing arm is being caught between rope device and the steel rope.
Further improvement of the utility model is: the described rope device outer end of catching upwards bends.
Because the technological advance that has adopted technique scheme, the utility model to obtain is:
The utility model falls the rope situation by what misalignment sensor monitored steel rope, catching the rope device can stop steel rope to continue to drop, guarantee simultaneously when not taking measures to allow steel rope reset, swing arm on the misalignment sensor keeps the state that is triggered, misalignment sensor continues to give a warning, up to getting rid of potential safety hazard, guaranteed the safety of staff and equipment.
Catch the upwards bending of rope device outer end, can go into to catch the rope device along the slope landing of bending when steel rope drops, prevent that steel rope from continuing to fall.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further details:
The steel rope monitoring device that falls to restrict, concrete structure comprise misalignment sensor 3 and catch rope device 4 as shown in Figure 1 and Figure 2.Described misalignment sensor 3 is arranged on steel rope 1 below, can be used for monitoring the mode of operation of steel rope 1; Catch rope device 4 and be fixedly installed on the anchor shaft of rope sheave 6, be used to stop steel rope 1 to drop to rope sheave 6 belows by support 5.Catch the upwards bending of rope device 4 outer ends, can go into to catch rope device 4 along the slope landing of bending when steel rope 1 drops.Catch rope device 4 and be arranged on the below of steel rope 1, misalignment sensor 3 is fixedly installed on the end face of catching rope device 4.The structure of misalignment sensor 3 as shown in Figure 5, misalignment sensor 3 is provided with swing arm 2, swing arm 2 is hinged by bearing pin and misalignment sensor 3.Whether swing arm 2 is arranged on catches between rope device 4 and the steel rope 1, be used to monitor steel rope 1 and drop.
Concrete working process of the present utility model is:
In rope sheave 6 and steel rope 1 equal normal course of operation, steel rope 1 is in the race of rope sheave 6, catches rope device 4, misalignment sensor 3 and swing arm 2 and all is in normal condition, and the each several part position as shown in Figure 4.
After steel rope 1 drops, catch rope device 4, misalignment sensor 3 and swing arm 2 positions relation as shown in Figure 3 from the race of rope sheave 6.The steel rope 1 that drops touches swing arm 2 earlier, after misalignment sensor 3 is sensed the triggering state of swing arm 2 in monitoring, send the signal that steel rope 1 drops to control desk, steel rope 1 presses down swing arm 2 and continues afterwards, when fall to catch the rope device 4 on the time, stop after going into to catch in the rope device 4 by the slope landing of catching the 4 outer ends bending of rope device, this moment, swing arm 2 still was under the pressure effect of steel rope, can not reply the normal position.Misalignment sensor 3 continues to sense the signal of swing arm 2, continues to send signal to control desk.The staff sends halt instruction according to steel rope 1 failure message that control desk shows.After the steel rope 1 that drops was hung to the race of rope sheave 6 again, swing arm 2 resetted.This moment, potential safety hazard was eliminated fully, and whole mining built on stilts manned ropeway can restart, and continued operation.
