Abstract
The invention discloses a broken rope catching device comprising a frame, a link mechanism, a buffer spring, an electric push rod, catching wedge blocks, a base and a rope supporting pulley. Each catching wedge block comprises an upper wedge block, a guide belt, stroke pins, a lower wedge block and a brake shoe, wherein the upper wedge block is connected with the guide belt through grooved countersunk head screws; the guide belt is connected with the lower wedge block through another grooved countersunk head screws; the upper wedge block is connected with the lower wedge block through the stroke pins; and the lower wedge block is connected with the brake shoe through inner hexagon screws. The frame is in pin connection with the link mechanism; the link mechanism is in pin connection with the buffer spring; the buffer spring is in threaded connection with the electric push rod; the catching wedge blocks are hinged with the link mechanism; the base is welded with the frame; and the rope supporting pulley is in bolted connection with the frame. The broken rope catching device has a simple and reasonable structure, is safe and reliable, and can promptly and effectively catch a rope after the rope is broken during the running of equipment, so as to prevent the rope from falling down, increase the safety factor of the equipment, reduce loss and save a great amount of manpower and material resources.
Description
Technical field
The present invention 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 technical solution adopted for the present invention to solve the technical problems is: 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.
Summary of the invention
The purpose of this invention is to provide a kind of disconnected rope grip device for catching.
The objective of the invention is to realize through following technical scheme:
Disconnected rope grip device for catching of the present invention 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 the invention described above provides can be found out, disconnected rope grip device for catching of the present invention 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
Disconnected rope grip device for catching of the present invention, 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.
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.
Disconnected rope grip device for catching of the present invention has following inventive 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 invention has the beneficial effects as follows:
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 present invention, but protection scope of the present invention is not limited thereto, any technical personnel of being familiar with the present technique field is in the technical scope that the present invention discloses; The variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.
