Abstract
The invention relates to the technical field of gateway stretchable belt conveyor braking devices used in coal mine, in particular to a device with controllable damping force. A damping device with controllable hydraulic pressure is used for a gateway stretchable belt conveyor under the coal mine and is applicable to the working condition of downward transportation with a large dip angle. The damping device with the controllable hydraulic pressure solves the braking problem of the downward transportation stretchable belt conveyor. The damping device with the controllable hydraulic pressure is structurally characterized in that a damping plate assembly is not fixed in the longitudinal direction, a pin and a long groove are used as a track, the tightness of a steel wire rope is controlled by a hydraulic cylinder to adjust the height of the damping plate assembly, namely the contact degree between the damping plate assembly and a conveyer belt is controlled, adjustment of the frictional resistance coefficient is achieved, negative problems caused by underworkings downward transportation with the large dip angle are solved, and negative effect of a traditional method is avoided. The damping device with the controllable hydraulic pressure has the advantages of being simple in structure, convenient to machine, low in cost, strong in adaptive capacity, reliable, and practical.
Description
Technical field
The present invention relates to the technical field of a kind of colliery with crossheading extensible belt conveyor brake equipment, is the adjustable device of a kind of dumping force specifically.Be used for the coal mine downhole crossheading extensible belt conveyor, be applicable to fortune operating mode under the high spud angle, to solve down the braking problem of fortune extensible belt conveyor.
Background technology
Traditional crossheading extensible belt conveyor damping arrangement, the support body keystone configuration is the framing member that is welded by channel-section steel, and be installed in by bolt on the crossbeam of carrier roller frame centre, damping panel is by being bolted on the damping frame, and the exposure level of itself and load-transfer device immobilizes in the operational process, offsets the sliding force of material for making its dumping force that produces, requirement is bigger, and when the inclination angle is big,, the possibility that faces inefficacy is arranged because the dumping force that is produced is limited.
Traditional crossheading extensible belt conveyor damping arrangement, because it contacts with load-transfer device all the time, in operational process, increase the wearing and tearing of load-transfer device and belt clamps, 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 invention is to provide a kind of hydraulic pressure controllable damp device, this device is easy to process, and cost is low, and adaptive capacity is strong, can solve the counter productive that high spud angle is transported operating mode down and eliminated traditional damping arrangement by actv..
The technical solution adopted for the present invention to solve the technical problems is: 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 hydraulic rams 1 are the controlled major parts of hydraulic pressure, by being bolted on the basis, connect with steel rope by piston rod; Assembly pulley 2 is made up of a bearing pin and a wheel body, regulates the damping arrangement maximum displacement by regulating its setting height(from bottom) H; Steel rope 3 is a 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, on the crossbeam that is bolted to middle frame, longeron is welded with the pin that is connected with the damping panel assembly, and the 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 that connects on the channel-section steel, with this as dragging track; Fixedly winch 6 mainly is made up of a cylindrical shell and set pin and bearing pin, wherein bearing pin is welded on the belt self-movable foot end side plate, barrel jacket makes it spacing on bearing pin on the bearing pin and by set pin, when the advance of the face need be torn frame open, pull up set pin, rotating cylinder can twine the steel rope that has more and reclaim.
Beneficial effect of the present invention:
Solved the underworkings high spud angle and transported the negative issue that brings down,, damping arrangement and load-transfer device have been broken away from, avoided the wearing and tearing of load-transfer device and belt clamps by the height of regulator solution compressing cylinder; 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 crossheading belt conveyer, and has improved the counter productive of traditional approach.
Description of drawings
Below in conjunction with accompanying drawing and specific embodiments the present invention is described in further detail:
Fig. 1 is the structural representation of invention;
Fig. 2 and Fig. 3 are respectively the cross sectional drawing of the present invention under operation and braking two states.
Among the 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 is meant: the hydraulic ram that is fixed on the basis realizes regulating the height of damping arrangement by relaxing of steel rope of control, achieves the control that damping arrangement is produced the dumping force size.
Specific operation process:
When the crossheading extensible belt conveyor normally moves, needn't modulated pressure oil cylinder 1, promptly 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 closed contact; the dumping force that produces can be offset the sliding force of material, has guaranteed the orderly closedown of belt conveyer, makes that also the life-span of load-transfer device, belt clamps is influenced less simultaneously.When the advance of the face need be torn frame open, damping arrangement was also and then dismantled, and extract the set pin on the jinny 6 this moment, and the cylindrical shell on the rotating pin reclaims the steel rope that has more.
Claims (1)
