Abstract
A sub-step broken-belt protective device for a belt conveyer comprises a support, a lower rubber belt, braking carrier rollers, an upper rubber belt, rubber belt carrier rollers, a drive roll and power switches. A catcher component is installed on the support and is provided with a magnetic exchange valve. The rubber belt carrier rollers close to the catcher component are respectively provided with a shaft encoder. The drive roll is also provided with a shaft encoder. All the shaft encoders, the magnetic exchange valve of the catcher component and the power switches are respectively connected with a programmable logic controller (PLC) control cabinet through signal lines. Response is caught in time through acquisition of a speed signal. A first catching claw adjusts pre-tighten value according to practical requirements and belt speed of a broken belt can be effectively reduced. A second catching claw and a lower catching claw are in linkage, catching effects are good, and a possible second time belt break caused by a super braking force is avoided. The sub-step broken-belt protective device for the belt conveyer is simple in structure, high in sensitivity, and good in braking effect.
Description
Technical field
The utility model relates to a kind of belt conveyer technical field, relates in particular to the high-power belt-break protection device for rubber belt conveyor of high spud angle large conveying quantity under the coal mine.
Background technology
Belt conveyer is one of transportation device crucial under the coal mine.But because long-term high loaded process, frequent start-stop and some unexpected factors of adhesive tape are directly pounded adhesive tape or metal object jam etc. such as spoil, can cause the unexpected fracture of metal tape.Especially for present application steel cable belt more widely, because the corrosion of Steel cord, fracture or because of the twitch of adhesive tape vulcanizing wire joint wire rope core all might make adhesive tape generation cross break.The inclination angle is large, distance, upper conveying belt type conveyer that freight volume is large, in case the reverse accident that broken belt glides or holdback lost efficacy and causes occurs, will destroy carrying roller, limit pipe, frame cable and electric equipment and smallclothes, cause the bulk deposition of adhesive tape and material and stop production, when serious even cause casualties.Therefore, the safety guard-safeguard facility of travelling apron is an extremely important ring in the safety of coal mines regulations.The issue of Coal Mine Safety Supervision Bureau of country, " safety regulations in coal mine " the 7th section of the 375th article regulation of formally implementing from January 1st, 2005: " the Steel cord belt conveyer should be established belt break protection device for belt conveyor ".
The maximum broken belt catcher of domestic present use can be divided into two classes, and a class is the fault-belt catching device of grabbing the limit formula, and another kind of is full section break catching apparatus.Their shortcoming is: be once braking, the braking force size is indefinite, and the damage to belt during braking is larger, very easily causes the secondary broken belt.
Summary of the invention
The purpose of this utility model be overcome in the prior art deficiency it, the belt conveyer that a kind of simple in structure, good braking effect is provided is with the substep belt break protection device.
For achieving the above object; belt conveyer of the present utility model substep belt break protection device; comprise support, lower adhesive tape, brake carrier roller, adhesive tape, belt idler, head roll, power switch; at described support the catching device assembly is installed; the catching device assembly is provided with solenoid directional control valve; be separately installed with shaft encoder near on the belt idler of catching device assembly; shaft encoder also is installed on the described head roll, and the solenoid directional control valve on all shaft encoders, the catching device assembly is connected signal wire (SW) and is connected with the PLC control box respectively with power switch.
Described catching device assembly comprise symmetry be located at adjacent two brake carrier rollers top, can push adhesive tape first and second arrest pawl, the second top of arresting the corresponding lower adhesive tape of pawl is provided with cross sill, the below of cross sill is provided with the lower pawl of arresting that can push lower adhesive tape, first arrests pawl is provided with elastic parts, and the elastic parts upper end is provided with the sleeve with its sliding block joint; Second arrest pawl and under arrest pawl and be fixed on the same axis through upper and lower sprocket wheel respectively, upper and lower sprocket wheel connects by the chain closed loop, first and second is arrested pawl and is fixed on the crank through rocking bar respectively, the front portion of crank is provided with hydraulic actuating cylinder, and the fuel feed hole at hydraulic actuating cylinder two ends links to each other with solenoid directional control valve, Hydraulic Pump successively by transport pipe respectively.
Described elastic parts comprises spring, is located at the upper and lower back-up ring of spring top and the bottom, and upper back-up ring is provided with pre-load nut, and packing ring is arranged in the middle of pre-load nut and the upper back-up ring.
Described first and second arrested pawl and is circular arc with lower head of arresting pawl.
Beneficial effect: the utility model is braked during by broken belt in two steps, and the first step reduces the broken belt belt speed, and second step is then with broken belt braking chucking.The multiple spot shaft encoder is set, the Negotiation speed acquisition of signal, in time arrest response, first arrests pawl regulates the pretension amount according to the actual requirements, can effectively reduce the broken belt belt speed, second arrests pawl and lower arrests the pawl interlock, arrests respond well and can avoid owing to the excessive possible secondary broken belt that causes of braking force.Arresting pawl has certain distance apart from adhesive tape when belt conveyer works, can not contact goods formation gear and cut or overflow, also can not touch during rubber belt from deviating and arrest pawl.Its simple in structure, highly sensitive, good braking effect have widely practicality in the art.
