Abstract
The utility model relates to the technical field of crossheading telescopic belt-type conveyor braking devices for coal mines, in particular to a damping-force-adjustable device, wherein the damping-force-adjustable device is used for a coal mine underground crossheading telescopic belt-type conveyor, is applicable to large-dip-angle downward transportation working conditions and aims at solving the braking problem of the downward telescopic belt-type conveyor. The device is structurally characterized in that damping plate components are not fixed in the vertical direction, a hydraulic cylinder controls the tightness state of a steel wire rope so as to adjust the height of the damping plate components in the mode that pins and a long groove form a track, namely, the contacting degree between the damping plate components and a conveyor belt is controlled, adjustment to the friction resistance coefficient is achieved, therefore, the negative problems brought by underground roadway large-dip-angle downward transportation are solved, and the negative effects of a traditional mode are avoided. The device is simple in structure, convenient to machine, low in cost, strong in adaptability, reliable and applicable.
Description
Technical field
The utility model relates to the brake equipment of a kind of colliery with the crossheading extensible belt conveyor, the adjustable device of a kind of dumping force specifically, for the coal mine downhole crossheading extensible belt conveyor, be applicable to transport operating mode under high spud angle, to solve the braking problem of lower fortune extensible belt conveyor.
Background technology
Traditional crossheading extensible belt conveyor damping arrangement, the support body keystone configuration is the framing member be welded by channel-section steel, and be arranged on the middle crossbeam of carrier roller frame by bolt, damping panel is bolted on damping frame, and in operational process, the exposure level of itself and load-transfer device immobilizes, for the dumping force that it is produced is offset the sliding force of material, requirement is larger, and, when inclination angle is larger, because produced dumping force is limited, the possibility that faces inefficacy is arranged.
Traditional crossheading extensible belt conveyor damping arrangement, because it is contacted with load-transfer device all the time, increase the wearing and tearing of load-transfer device and belt clamps in operational process, had a strong impact on the service life of load-transfer device and belt clamps, increased the working service cost of equipment.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic pressure controllable damp device, and this device is easy to process, and cost is low, adaptable, can solve under high spud angle the counter productive of transporting operating mode and eliminating traditional damping arrangement by actv..
The utility model solves the technical scheme that its technical matters adopts: the hydraulic pressure controllable damp device can be divided into six parts: hydraulic ram 1, assembly pulley 2, steel rope 3, damping support body 4, damping panel assembly 5, jinny 6.Damping support body 4 is connected with elongated slot for pin with damping panel assembly 5, and damping support body 4 is bolted on middle frame, and steel cable 3 runs through damping panel assembly 5 bottoms simultaneously, and the one end is connected to hydraulic ram 1, and the other end is fixed on the jinny 6 of tail.
Hydraulic ram 1 is the controlled major part of hydraulic pressure, is bolted on basis upper, by piston rod, with steel rope, is connected; Assembly pulley 2 is comprised of a bearing pin and a wheel body, by regulating its setting height(from bottom) H, carrys out damping adjusting device maximum displacement; Steel rope 3 is round-strand rope, can carry out specification according to the operational throughput of belt conveyer and choose; Damping support body 4 is framing members that are welded by channel-section steel, be bolted on the crossbeam of middle frame, longeron is welded with the pin be connected with the damping panel assembly, and below is welded with a transverse slat and a riser, realizes carrying out spacing to the steel rope that laterally reaches of damping panel assembly; Damping panel assembly 5 is framing members that are welded, and damping panel is that three sheet steels are linked together by being hinged to grooved, and assembly is connected with the pin of damping support body by the elongated slot connected on channel-section steel, usings this as dragging track; Fixedly winch 6 mainly is comprised of a cylindrical shell and set pin and bearing pin, wherein bearing pin is welded on belt self-movable foot end side plate, barrel jacket makes it spacing on bearing pin on bearing pin and by set pin, when the advance of the face need be torn frame open, pull up set pin, rotating cylinder can reclaim the wirerope-winding had more.
The beneficial effects of the utility model:
Solve the negative issue that under the underworkings high spud angle, fortune is brought, by the height of regulator solution compressing cylinder, during operation, made damping arrangement and load-transfer device break away from, avoided the wearing and tearing of load-transfer device and belt clamps; During shutdown, the damping arrangement action, the dumping force of its generation can be offset the sliding force of material, guarantees the orderly closedown of gate trough-belt conveyer, and has improved the counter productive of traditional approach.
The accompanying drawing explanation
Below in conjunction with accompanying drawing and specific embodiments, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 and Fig. 3 are respectively the cross sectional drawing of the utility model under operation and braking two states.
In figure: 1. hydraulic ram, 2 assembly pulleys, 3. steel rope, 4. damping support body, 5. damping panel assembly, 6. jinny.
The specific embodiment
The hydraulic pressure controllable damp device refers to: be fixed on basic hydraulic ram by controlling the lax height of realizing the damping adjusting device of steel rope, achieve the control that damping arrangement is produced to the dumping force size.
Specific operation process:
When the crossheading extensible belt conveyor normally moves, needn't adjust hydraulic ram 1, keep the relaxed state of steel rope 3, damping panel assembly 5 and load-transfer device are broken away from.When shutting down; hydraulic ram 1 is by the pumping plant feed flow; piston rod descends; tense wire rope 3 makes damping panel assembly 5 rise; itself and load-transfer device close contact; the dumping force produced can be offset the sliding force of material, has guaranteed the orderly closedown of belt conveyer, also makes the life-span of load-transfer device, belt clamps influenced less simultaneously.When the advance of the face need be torn frame open, damping arrangement is also and then dismantled, and now the set pin on jinny 6 is extracted, and the cylindrical shell on rotating pin is reclaimed the steel rope had more.
