Description
Technical field
The utility model relates to a kind of disconnected rope grip device for catching.
Background technology
Present breaking rope protecting mainly is when disconnected rope takes place steel rope, and main motor is cut off, and steel rope is not had corresponding protection, and steel rope is in self gravitation and chair lift and take advantage of tunnel, people's action of gravity lower edge to glide, and makes the safety of mine personnel receive very big threat.
The utility model solves the technical scheme that its technical matters adopted: make full use of the existing built on stilts structure of taking advantage of people's car, disconnected rope grip device for catching is installed on the holder rope sheave.Device adopts electric pushrod to drive, and the response of electric pushrod is very fast, has solved to arrest response problem.Electric pushrod is through PLC control, and the I/O contact of PLC links to each other with pulling force sensor, and the back pull sensor of restricting when breaking sends signal, the action of PLC control electric pushrod.Adopt jointed gear unit, solved the interference problem of chair lift operational process neutralising arrangement.Arrest head and adopt the voussoir self-locking to clamp principle, strengthened the effect of arresting steel rope.Arrest device recoil spring is installed, can cushion the impulsive force that produces when arresting steel rope, in case cause the disconnected rope of secondary.The apparatus structure symmetry can produce two free ends behind the wire rope breaking, and symmetrical configuration can realize two-way arresting.
The utility model content
The purpose of the utility model provides a kind of disconnected rope grip device for catching.
The purpose of the utility model realizes through following technical scheme:
The disconnected rope grip device for catching of the utility model comprises frame, connecting rod mechanism, recoil spring, electric pushrod, arrests voussoir, base and holder rope sheave.Arrest voussoir and comprise voussoir, guidance tape, stroke pin, lower wedge block and brake shoe, last voussoir is connected through slotted countersunk flat head screw with guidance tape, and guidance tape is connected through slotted countersunk flat head screw with lower wedge block; Last voussoir is connected through the stroke pin with lower wedge block; Lower wedge block is connected through socket head cap screw with brake shoe, and frame is connected through bearing pin with connecting rod mechanism, and connecting rod mechanism is connected through bearing pin with recoil spring; Recoil spring and electric pushrod are through being threaded; Arrest voussoir and connecting rod mechanism is hinged, base and frame welding, holder rope sheave and frame are passed through bolted connection.
Technical scheme by above-mentioned the utility model provides can be found out, the described disconnected rope grip device for catching of the utility model is simple and reasonable; Safe and reliable; Can behind the disconnected rope of equipment operation, arrest rope timely and effectively, prevent the whereabouts of rope, improve the safety factor of equipment; Reduce loss, saved lot of manpower and material resources.
Description of drawings
Fig. 1 is disconnected rope grip device for catching structural representation;
Fig. 2 is for arresting the wedge structure scheme drawing.
The specific embodiment
The disconnected rope grip device for catching of the utility model, the specific embodiment that it is preferable such as Fig. 1, shown in Figure 2, disconnected rope grip device for catching comprise frame 1, connecting rod mechanism 2, recoil spring 3, electric pushrod 4, arrest voussoir 5, base 6 and holder rope sheave 7.
Arrest voussoir 5 and comprise voussoir 8, guidance tape 9, stroke pin 10, lower wedge block 11 and brake shoe 12; Last voussoir 8 and guidance tape 9 are connected through slotted countersunk flat head screw; Guidance tape 9 and lower wedge block 11 are connected through slotted countersunk flat head screw; Last voussoir 8 is connected through stroke pin 10 with lower wedge block 11, and lower wedge block 11 and brake shoe 12 are connected through socket head cap screw.
Frame 1 and connecting rod mechanism 2 are connected through bearing pin; Connecting rod mechanism 2 and recoil spring 3 are connected through bearing pin, and recoil spring 3 and electric pushrod 4 be through being threaded, and it is hinged with connecting rod mechanism 2 to arrest voussoir 5; Base 6 and frame 1 welding, holder rope sheave 7 passes through bolted connection with frame 2.
The disconnected rope grip device for catching of the utility model has following innovative point:
Disconnected rope grip device for catching is provided with recoil spring, can cushion the impulsive force that produces when arresting steel rope, and actv. prevents the disconnected rope of equipment secondary;
Disconnected rope grip device for catching is arrested between last voussoir and the lower wedge block of voussoir and is provided with two-layer guidance tape, has good Corrosion Protection, the friction that can actv. reduces to go up voussoir and lower wedge block, and the service life of rope grip device for catching is resolved in prolongation;
Last voussoir and lower wedge block that disconnected rope grip device for catching is arrested voussoir adopt wedge structure, can the actv. self-locking clamp, and prevent that rope from gliding.
Further specify below in conjunction with the principle of work of accompanying drawing disconnected rope grip device for catching:
Disconnected rope grip device for catching is installed in that the colliery is built on stilts takes advantage of on the holder rope sheave of people's car, and when steel rope generation rope-broken accident, disconnected rope signal is sent to PLC rapidly; The action of control electric pushrod, electric pushrod promotes transmission device, and the lower wedge block of arresting voussoir can be descended rapidly; Steel rope is clamped; Steel rope descends along wedge surface, forces lower wedge block and last voussoir to press tighter and tighter, forms self-locking.
The beneficial effect of the utility model is:
Simple and reasonable, safe and reliable;
Can behind the disconnected rope of equipment operation, arrest rope timely and effectively, prevent the whereabouts of rope, improve the safety factor of equipment, reduce loss;
Saved lot of manpower and material resources.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
