Abstract
The utility model discloses a trigger mechanism for a broken belt grasping device of a belt conveyor, and belongs to the field of belt conveyors. The trigger mechanism for the broken belt grasping device of the belt conveyor comprises a reversal carrier roller and a long shaft, wherein the reversal carrier roller is installed on the long shaft and can rotate only in one direction, and the long shaft and the reversal carrier roller rotate in the same direction. The trigger mechanism for the broken belt grasping device of the belt conveyor further comprises a rope-shaped object, a vertical pin and a trigger shaft, wherein the lower end of the vertical pin penetrates through a through hole of a fixing base, one end of the rope-shaped object is connected with the long shaft, the other end of the rope-shaped object is connected with the upper end of the vertical pin, one end of the trigger shaft is tightly attached to the side face of the vertical pin, and the other end of the trigger shaft is connected with a spring and installed in the fixing base. By the installation of the trigger mechanism, when a belt breaks down, the long shaft drives the rope-shaped object to enable the vertical pin to move upwards, then the trigger shaft is compressed by the spring, moves leftwards and triggers and starts a brake board to operate, and then the broken belt grasping device is triggered. The trigger mechanism is quick in response, and the broken belt grasping device can be triggered easily.
Description
Technical field
The utility model relates to a kind of belt conveyer broken belt catcher trigger mechanism, belongs to belt conveyer field.
Background technology
Nowadays, belt conveyer has become the main load transfer device of bulk material and lump material, is widely used in the industries such as coal, metallurgy, electric power, chemical industry, harbour and building materials.Once yet load-transfer device occurs that broken belt glides or the reverse accident that lost efficacy and cause because of holdback, will destroy conveyer frame, damage equipment, obstruction belt heading, causes long stopping production and heavy economic losses.For ruptured belt accident, current topmost safety method is installed belt break protection device exactly on conveyer, is also referred to as broken belt catcher.In recent years, occurred broken belt catcher or the technology such as mechanical type, fluid pressure type both at home and abroad, and there is the situation about triggering of being difficult for while there is broken belt under the large section of belt, large conveying quantity operating mode in Purely mechanical belt transporter broken belt catcher.Therefore need to propose a kind of novel trigger mechanism, while occurring to overcome broken belt, break catching apparatus is difficult for situation about triggering.
Summary of the invention
The problem existing for above-mentioned prior art, the utility model provides a kind of belt conveyer broken belt catcher trigger mechanism, and this utility model reaction is quick, and broken belt catcher is easily triggered.
To achieve these goals, the technical solution adopted in the utility model is: a kind of belt conveyer broken belt catcher trigger mechanism, comprise check carrying roller, major axis, check carrying roller is arranged on major axis, check carrying roller is single direction rotation only, major axis and check carrying roller rotating Vortex, also comprise ropy, perpendicular pin and beating shaft, described perpendicular pin lower end is through the through hole of permanent seat, ropy one end is connected with major axis, the other end is connected with perpendicular pin upper end, and beating shaft one end is close to side, the other end linking springs of perpendicular pin and is arranged in permanent seat.
Conductor rope cover of described perpendicular pin upper ends, ropy is connected with perpendicular pin through conductor rope cover.
In the middle of described perpendicular pin, have a chute, perpendicular pin upper end is fixed on support by the bearing pin that can slide in chute.
That one end that described beating shaft is close to perpendicular pin is circular groove, and circular groove is corresponding with the lateral dimension of perpendicular pin.
By this utility model is installed, when broken belt is occurred, major axis pulls ropy to make perpendicular pin upward movement, and then makes beating shaft oppressed by spring, goes out permanent seat, and beating shaft triggers slipper, and broken belt catcher is triggered.Reaction is quick, and broken belt catcher is easily triggered.

Wherein, 1, check carrying roller, 2, ropy, 3, conductor rope cover, 4, bearing pin, 5, perpendicular pin, 6, permanent seat, 7, beating shaft, 8, spring, 9, end cap, 10, screw, 15, major axis, 16, bearing, 17, support, 18, belt.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, the utility model comprises check carrying roller 1, major axis 15, two check dragging rollers 1 are arranged on major axis 15, major axis 15 is fixed on crossbeam by bearing 16, check carrying roller 1 is single direction rotation only, major axis 15 and check carrying roller 1 rotating Vortex, also comprise ropy 2, perpendicular pin 5 and beating shaft 7, described perpendicular pin 5 lower ends are through the through hole of permanent seat 6, ropy 2 one end are connected with major axis 15, the other end is connected with perpendicular pin 5 upper ends, beating shaft 7 one end are close to the side of perpendicular pin 5, other end linking springs 8 is also arranged in permanent seat 6, permanent seat 6 is arranged on crossbeam, an end cap 9 is installed in spring 8 outer ends, and be arranged on permanent seat 6 with screw 10.Conductor rope cover 3 of described perpendicular pin 5 upper ends, ropy 2 is connected with perpendicular pin 5 through conductor rope cover 3, and described conductor rope cover 3 is welded on support 17.In the middle of described perpendicular pin 5, have a chute, perpendicular pin 5 upper ends are fixed on support 17 by the bearing pin 4 that can slide in chute.That one end that described beating shaft 7 is close to perpendicular pin 5 is circular groove, and circular groove is corresponding with the lateral dimension of perpendicular pin 5.
During belt 18 normal operation, forward under the friction force that check carrying roller 1 produces in belt 18 motions drives, now major axis 15 does not turn; When belt 18 due to broken belt reversing sense when motion, under the friction force that check carrying roller 1 produces in belt 18 motions, reverse, major axis 15 is by back-stop mechanism and carrying roller rotating in same direction, now ropy 2 starts to be wrapped on major axis 15; When belt 18 counter motion certain distance, described ropy 2 starts to tighten, and the perpendicular pin of drive 5 upward movements, bearing pin 4 can move in the chute of perpendicular pin 5, until perpendicular pin 5 is extracted completely from permanent seat 6 corresponding apertures, now the resistance of beating shaft 7 fluted one end disappears, beating shaft 7 under spring force promotes its to left movement, work when triggering and starting slipper and start, and then broken belt catcher is triggered.
