Detailed Description
In order to make the objects and advantages of the present invention more apparent, a belt conveyor capable of preventing sidesway impact according to the present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 2 and fig. 3, the belt conveyor capable of preventing side-sway impact comprises two oppositely arranged support structures 1, wherein the support structures 1 are connected with fixed frames 2, the fixed frames 2 are provided with two oppositely arranged connecting shafts 3, and two ends of each connecting shaft 3 are connected with hook bodies 5 through torsion springs 4; adjacent hooks 5 on different connecting shafts 3 are connected through a first connecting line 6; the two first connecting lines 6 are connected through two second connecting lines 7; the second connecting line 7 passes through the ring piece 9; third connecting lines 10 respectively penetrate through two ends of the ring piece 9; one end of each of the two third connecting lines 10 is connected with a speed difference anti-falling device 11, and the other end is connected with the end part of a heavy hammer roller 12; the speed difference anti-falling device 11 is fixedly connected with a fixed seat 8; an air bag 13 is fixed on the side surface of the supporting structure 1, the air bag 13 is communicated with an inflating device 14, and the inflating device 14 is in communication connection with a tape breakage sensing device.
The supporting structure 1 is a wall or a frame body.
The speed difference anti-falling device 11 is a ratchet speed difference anti-falling device.
The speed difference anti-falling device 11 is an electromagnetic rheological damper.
The first connecting line 6, the second connecting line 7 and the third connecting line 10 are all steel wire ropes.
The fixed seat 8 is fixedly connected with the fixed frame 2.
The tape break sensing means is a torsion sensor 14 connected to the torsion spring 4. The inflation device 14 is an air pump.
When the belt conveyor normally works, the torsion spring provides certain tension to enable the steel wire rope to be kept in a horizontal state firstly, the speed difference anti-falling device is connected with the heavy hammer, namely the heavy hammer roller, and the normal up-down running speed generated by the heavy hammer is extremely low under the normal work, so that the in-and-out of the steel wire rope in the speed difference anti-falling device cannot be influenced. When the rubber belt is broken, the heavy hammer suddenly and violently drops, the speed is high, the ratchet wheel in the speed difference anti-falling device is locked, the steel wire rope cannot stretch, the steel wire rope connected with the torsion spring starts to bear the load, the torsion spring is compressed, the horizontal steel wire rope is changed into an angle, however, the angle is small, the whole system is mainly only subjected to two horizontal forces which are mutually offset, the heavy hammer is changed into six-point load from two-point load, the vertical acting force on a floor slab in contact with the heavy hammer is small, and therefore the safety is guaranteed. When the adhesive tape is broken, the torsion spring 4 is increased and exceeds a set threshold value, the torsion sensor 14 senses the torsion, the air pump is controlled to inflate, the air bag clamps the heavy hammer, and therefore the side swing of the heavy hammer is prevented from damaging the supporting structure.
Example 2
As shown in fig. 4, the tape breakage sensing means is a tension sensor 15 connected to the third connecting wire 10 in the embodiment 1. That is, whether the tape is broken or not is sensed by the tension sensor 15, and the air pump is controlled.
Example 3
As shown in fig. 5, on the basis of embodiment 1, the tape break induction apparatus includes a spiral coil 16 disposed on the side of the support structure 1; the spiral coil 16 is electrically connected with a current meter 20 to form a loop and is arranged along the height direction of the supporting structure 1; an air bag 13 is arranged between the adjacent speed measuring sensors 16; the air bag 13 is communicated with a main pipe 18 through a branch pipe 17, the main pipe 18 is communicated with the inflating device 14, the branch pipe 17 is installed on an electromagnetic valve 19, and an ammeter 20 is in communication connection with the electromagnetic valve 19 and the inflating device 14; magnets matched with the galvanometer 20 are arranged on two sides of the weight roller 12.
Thus, when weight roller 12 moves up and down, spiral coil 16 is magnetically cut, and current meter 20 generates an induced current. When the sticky tape broke, weight roller 12 had a speed that sharply descends, and induced-current at this moment surpassed and set for the threshold value, then control corresponding solenoid valve and correspond the solenoid valve that closes on of solenoid valve and air pump and open to quick inflation makes the accurate tight weight roller 12 of pressing from both sides of gasbag, prevents its side sway. Compared with the embodiments 1 and 2, the embodiment has the advantages that only the air bags at the corresponding positions are inflated, so that the air bags can be rapidly inflated.
The above is merely an example of the present invention and is not intended to limit the scope of the present invention, and any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
