Abstract
The utility model relates to a broken belt catcher used for the security protection of a belt conveyor, which belongs to the transmission machine. The utility model comprises a one-way transmission gear, a transmission shaft, a non-return device, a rope rolling drum, a steel-wire rope sleeve and a frame for the steel-wire rope sleeve. The utility model has the characteristics of simple structure, quick reaction, and reliable belt clamping.
Description
The utility model relates to a kind of adhesive tape delivery safety fender guard, belongs to the transmission mechanical field.
Travelling apron is a kind of common short-range transport tool, the short range that is applicable to the loose unpacked material of mine, railway, harbour, large-size thermal power plant, saltern, grain depot and some integrated mills is carried, purposes is very extensive, the greatest weakness of travelling apron is that adhesive tape ruptures easily, large-scale travelling apron in particular for last fortune or following fortune, its adhesive tape is in case fracture, the number that delivers on the adhesive tape pours down along the slope immediately with tens tons of materials, cause the sliding accident of serious amplification, even the life security that threatens the tail operating personnel.At this problem; multiple safety guard had abroad once appearred; it generally all is electronically controlled mechanical clamping device; the sliding accident of amplification that the adhesive tape fracture is caused has certain containment effect; but because travelling apron is open-air or borehole operation; environmental conditions is very abominable; and fender guard often is to be in off working state for a long time; easily because of weathering; corrosion causes machinery malfunctioning or to cause adhesive tape to tear because of clamping face is less accidents caused; electronically controlled in addition safety device complex structure and cost height; especially borehole operation must be used explosion-proof electric apparatus.
The purpose of this utility model be to provide a kind of simple in structure, be swift in response, seize on both sides by the arms adhesive tape failure-free safety guard.
The utility model is achieved in that a kind of circuit belt stretching device, comprise unidirectional power wheel, rope sling, rope sling frame, cylinder, said unidirectional power wheel is installed on the transmission shaft, said transmission shaft laterally is installed in the tight below of the adhesive tape of travelling apron, the one end connects said cylinder, be provided with a non-return device between said transmission shaft and the travelling apron frame, on the adhesive tape and the said rope sling frame that is laid in of said rope sling around travelling apron, the end of rope sling fixedly is wrapped on the said cylinder.
The utility model has the advantages that: the run action of (1) whole protecting device all is a mechanical drive, does not need power supply, has only an emergency stop switch to be used to control the operation of travelling apron; (2) being active in one's movements of fender guard, seizure downslide adhesive tape is rapid and reliable, and maximum downslide amount is 5 meters after rupturing according to test detection adhesive tape; (3) device simple in structure, cost is low, easy for installation and current maintenance maintenance is convenient.
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the lateral plan of the utility model adhesive tape trap setting;
Fig. 2 is the sectional elevation of the utility model adhesive tape trap setting at the transmission shaft place.
The utility model adhesive tape trap setting comprises unidirectional power wheel 1, transmission shaft 2, check ratchet 5, serving cylinder 6, steel wire loop 4 and rope sling frame 3 thereof.As shown in the figure, transmission shaft 2 laterally is installed in travelling apron up and down on the frame between the adhesive tape, and the unidirectional power wheel 1 that the rubber rim is housed is installed in the middle part of transmission shaft, and tight village is in the bottom of last adhesive tape, as required, the desirable list of unidirectional power wheel is only or more than two or two.Serving cylinder 6 is contained in an end of transmission shaft, transmission shaft also is equipped with check ratchet 5, its sour jujube is because of fixing on the conveyer frame, the rope sling frame is installed in the adhesive tape gliding direction apart from about 2 meters of transmission shaft, adhesive tape is respectively adorned a steel wire loop 4 up and down, apply respectively in the upper and lower of rope sling frame, the fag end of rope sling fixedly is wrapped on the cylinder.
During the conveyer normal operation, unidirectional power wheel oppositely dallies with up last adhesive tape by friction-driven, and transmission shaft does not rotate.When adhesive tape ruptures, last adhesive tape glides rapidly, unidirectional power wheel just changes, and with transmission of power to transmission shaft, serving cylinder on the transmission shaft begins serving, cause the steel wire loop that applies on the rope sling frame to drop on the adhesive tape, and with the adhesive tape downslide, adhesive tape glides on the one hand, and the friction force of adhesive tape and rope sling tightens up rope sling very soon, the serving cylinder is constantly received to restrict to roll rope sling is tightened up very soon on the other hand, the combined action of two aspects makes the adhesive tape of downslide very fast by bundle firmly, and the check ratchet on the transmission shaft has guaranteed that the serving cylinder can only rotate to the direction of tight rope cover, can not put rope and cause that rope sling gets loose, thereby tightly adhesive tape be caught because of counter-rotating.In addition, an emergency stop switch is housed on the device,, makes the power-off of travelling apron motor even in a single day transmission shaft rotates this switch motion.
Claims (3)
1, a kind of circuit belt stretching device, it is characterized in that: comprise unidirectional power wheel, rope sling, rope sling frame, cylinder, said unidirectional power wheel is installed on the transmission shaft, said transmission shaft laterally is installed in the tight below of the adhesive tape of travelling apron, the one end connects said cylinder, be provided with a non-return device between said transmission shaft and the travelling apron frame, on the adhesive tape and the said rope sling frame that is laid in of said rope sling around travelling apron, the end of rope sling fixedly is wrapped on the said cylinder.
2, circuit belt stretching device according to claim 1 is characterized in that: said non-return device is a check ratchet.
3, circuit belt stretching device according to claim 1 is characterized in that: said unidirectional power wheel is more than one or two or two.
