Affiliated technical field
The present invention is the steel wire tensioning lock catch using during for the on-the-spot vulcanization gelatinization joint of steel cable core conveying belt or cold-adhered, adopt high-strength metal material sheet stamping convolution to form, this steel wire tensioning lock catch utilizes locking principle and the feature of anchor ear and hoop simultaneously, be divided into two kinds of forms of parallel staggered locking and butt-joint locking, make two steel wire tensioning lock catchs mutually support reinforcement and locking mutually, guarantee that wire rope can not get loose, from improving in essence joint quality and the Security of steel cable core conveying belt, can shorten interface length simultaneously, saving equipment, the expense of manpower and interface material and belt, improve the whole service life of conveyor belt.Use steel wire tensioning lock catch to coordinate cold-adhered technology, can solve the technical barrier of the cold-adhered of steel cable core conveying belt, Practical significance is huge.
Background technique
Steel cable core conveying belt is due to its high strength, low elongation, troughability waits well technological merit by port and pier, power plant, mine, the industrial and mining enterprise such as colliery are widely used, along with quantity delivered and belt speed significantly promote, the steel cable core conveying belt intensity of using is more and more higher, also more and more wider, also higher to the joint strength of steel cable core conveying belt and security requirement, because conveyor belt is being born the conveying responsibility of product or raw material, once there is the accident of interface fracture, the lighter affects production, severe one will produce the major accidents such as casualties, mine laneway particularly, the acclive field of employment such as band conveyer corridor, once prolonging ramp, conveyor belt fracture glides, stop up tunnel, if any field personnel in belt tunnel, to be very dangerous, and the difficulty that such accident recovery is produced is very big, cycle is longer, all there are every year many these type of accidents in the whole nation, therefore the quality of conveyor belt interface becomes one of problem that production manager pays close attention to most, due to conveyor belt interface quality, to transporting system safety and steady, operation plays a key effect, each large factories and miness take to conveyor belt interface the management method of comparatively guarding conventionally, the one, strengthen inspection or expensive belt monitoring instrument is installed, find that there is the damaged method of just taking to change conveyor belt or again doing interface at interface position.The 2nd, the length that extends belt interface, the safety coefficient of raising interface.The 3rd, the intensity of increase belt type selecting, improves safety coefficient.The processing mode of above-mentioned several correspondences does not all have from improving in essence the quality of belt interface, and has all directly increased cost and many unnecessary wastes.Due to involving great expense of steel cable core conveying belt, joint quality is poor is the main cause that directly affects the whole service life of conveyor belt, shortened the life cycle of conveyor belt, cause great waste, in addition repeatedly do joint material that interface needs, manpower maintenance cost, equipment investment and on the impact of safety in production etc., the annual loss therefore causing and waste will reach billions of units.Therefore the interface quality that how effectively to improve steel cable core conveying belt has a great economic significance and environment protection significance.The domestic and international connection for steel cable core conveying belt at present all adopts heat-vulcanized adhesive technology, method is that the rubber at conveyor belt two ends is divested, expose wire rope, polishing wire rope, smear vulcanzing agent, then be staggeredly placed on lower floor's half finished rubber the wire rope at two ends is parallel, use again one deck half finished rubber bedding on parallel staggered wire rope, upper and lower two-layer half finished rubber wire rope wraps, use the scene that half finished rubber sulfuration is realized to conveyor belt of heating, pressurize, vulcanization scene to reproduce, complete the docking at conveyor belt two ends.This bonding mode joint strength is to be determined by the bonding force of rubber and wire rope, namely pull and be bonded in the plug resistance that the wire rope in rubber produces, the size of plug resistance depends on the bonding force of rubber and wire rope, the length of the intensity of rubber body and adjacent two staggered arrangements of wire rope, conventionally interface is divided into one-level overlap joint and multistage overlap joint, the intensity of conveyor belt is larger, the progression of overlap joint is more, reason is that the intensity of conveyor belt is larger, the diameter of its framework material wire rope is just larger, the gap of wire rope and wire rope is just less, quantity that can staggered wire rope is just fewer, need the progression of overlap joint just more, the length of glueing joint and difficulty also increase thereupon, in the situation that interface length is identical, the progression of overlap joint is more, the intensity of interface will be lower, therefore use now the user of high strength wire rope core conveyer belt gradually interface length to be lengthened, the ST3500 shaped steel wire rope core conveyer belt of take is example, standard rubber connection interface length is 1600mm, and many factories and miness expand to 3000mm by interface length, even the interface length of some high strength wire rope core conveyer belt reaches 6000mm.Glued joint that interface is elongated brings following some drawback: the one, increase the sulfuration activity duration, increase the time and workload, vulcanizer carrying and the on-the-spot preparatory work amount that divest rubber on wire rope, the 2nd, increased the waste of belt and the consumption of cord rubber belt, the 3rd, the input of increase vulcanization apparatus and manpower, the 4th, because work on the spot environment is poor, sulfuration work surface is larger, the flaw of bonding by Vulcanization is just more, and the quality of splicing is just poorer.Therefore how to improve interface quality, make it to reach and conveyor belt equality strength, realize interface and conveyor belt and use and there is great Practical significance with the life-span.Why existing wire rope interconnection technique can not solve the connectivity problem of steel cable core conveying belt completely, the main uniqueness that is limited to steel cable core conveying belt requires: be first that the wire rope of the steel cable core conveying belt density of arranging is larger, gap is little, the rubber layer thickness covering is up and down limited, and defining snap close volume can not be excessive; Next be steel cable core conveying belt be in operation need horizontal and vertical folding repeatedly around, increased design difficulty; The 3rd is that wire rope surface attachment in conveyor belt has rubber, is relatively difficult to locked; Locking mode need to match with the arrangement mode of conveyor belt wire rope simultaneously, and therefore never having good processing mode solves this problem.
