It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

A protection device for a double-cone dryer is disclosed, as shown in fig. 1-3, comprising two fence mechanisms 1 and a locking mechanism 2, wherein the fence mechanisms 1 are arranged on two side supports of the double-cone dryer 3, the two fence mechanisms 1 are connected through the locking mechanism 2 to enclose a rotation space allowing the double-cone dryer, a worker normally works on only one side, therefore, one side is protected through the fence mechanism 1, the other side can also be protected by a fake fence mechanism 1, and the fence can also be protected by a fake fence mechanism 1, wherein the fence mechanism 1 comprises a cross bar 11, a fixed seat 12 and a limit switch 13, the fixed seat 12 is fixedly arranged on the double-cone dryer 3, one end of the cross bar 11 is rotatably arranged on the fixed seat 12, the limit switch 13 is arranged on the fixed seat 12 and used for sensing the cross bar 11, the limit switch 13 can use an electric shock switch or a proximity switch, when the fence mechanism is used, the cross bars 11 of the two side fence mechanisms 1 rotate oppositely, the fence mechanisms reach the locking position, namely the position after the two side fence mechanisms 1 are connected through the locking mechanism 2, the cross bar 13 can sense a signal, then transmit the signal to the stop the operation of the double-cone dryer, and further guarantee the safety operation of the double-cone dryer, if the double-cone dryer is finished, and the double-cone dryer, the double-cone dryer can be further, the safety control.

In one embodiment, as shown in fig. 1-3 and 5, the drying machine further comprises an elastic mechanism 4, the elastic mechanism 4 is arranged on the fixed seat 12, when the crosspiece 11 is unlocked, the crosspiece 11 is pushed away from the limit switch 13 by the elastic mechanism 4, it can be seen that if the elastic mechanism 4 is not arranged, a worker may fail in work, the fence mechanism 1 is not locked and only hidden, when the double-cone drying machine rotates, the fence mechanism 1 may be opened, and a certain safety hazard exists, and in addition, if the P L C sets the limit switch 13, a signal of the limit switch 13 is eliminated, and damage may be caused to the equipment, however, after the elastic mechanism 4 is arranged, even if the worker pushes the fence mechanism 1 to the locking position, if the locking mechanism 2 is not locked, the crosspiece 11 is pushed away from the limit switch 13 by the elastic mechanism 4, so that the P L C cannot receive the signal of the limit switch 13, even if the worker does not notice the locking mechanism 2, the worker cannot start the equipment when starting the equipment, the worker can pay attention to notice, the worker can carefully improve the locking mechanism 2, and further avoid the forced operation of the double-cone drying machine in the unlocking state.

In a specific embodiment, as shown in fig. 1-3 and 5, the elastic mechanism 4 includes a spring seat 41, a fixing cap 42, a bolt 43, and a spring 44, the spring seat 41 is fixed on the fixing seat 12, the spring seat 41 is in a U-shaped structure, and two side walls thereof are provided with a through guide hole 45, the spring 44 is sleeved on the bolt 43, and the other end thereof passes through the guide hole 45 and is fixed by the fixing cap 42, at this time, the spring 44 is located between the spring seat 41 and the end of the bolt 43, and is under the tension of the spring 44, so that the fixing cap 42 is tightly attached to the spring seat; when one end of the bolt 43 is pushed so that the fixing cap 42 is away from the spring seat 41, the spring 44 accumulates force; when the hand is released, the tension of the spring 44 urges the bolt 43 to move in the opposite direction.

In one embodiment, as shown in fig. 1-4, the locking mechanism 2 comprises a U-shaped locking plate 21, a linear locking plate 22 and a locking pin (not shown), and the U-shaped locking plate 21 and the linear locking plate 22 are correspondingly provided with a locking hole 23 and are respectively arranged on the crosspiece 11 of the two rail mechanisms 1. When the fence mechanism 1 is locked, the linear locking plate 22 is arranged in the middle of the U-shaped locking plate 21, the three locking holes 23 are on the same axis, the locking pins are inserted into the three locking holes 23, the three locking holes 23 are connected together, and the locking of the locking mechanism 2 is realized.

In one embodiment, as shown in fig. 1-3, the rail mechanism further comprises two bar magnets 7, wherein the bar magnets 7 are respectively arranged at the ends of the crosspiece rods 11 of the two rail mechanisms 1, and the opposite ends of the two bar magnets 7 have the same magnetic pole. That is, when the crosspiece rods 11 on both sides reach the locking position, the two ends of the two bar magnets 7 are opposite, and if the locking mechanism 2 is not locked, the crosspiece rods 11 are rotated to both sides by the mutual repulsive force of the two bar magnets 7, so that the limit switches 13 cannot sense the crosspiece rods 11. The principle that like poles of magnets repel each other is utilized, the attention of workers is improved, the workers are prevented from being scattered too late, and in order to facilitate production, the workers are not responsible for themselves and only the crosspiece rod 11 is hidden. Because, if the staff connects the crosspiece rods 11 on both sides at will, then the U-shaped locking plate 21 and the in-line locking plate 22 repel each other, under the condition that the staff does not operate, the alignment of the three locking holes 23 cannot be realized, and the limit switch 13 on at least one side cannot sense the crosspiece rods 11. Secondly, after the lock pin is inserted, the lock pin is firmly clamped in the lock hole 23 by utilizing the principle that like poles of magnets repel each other.

In the above embodiment, one of the solutions of installing the elastic mechanism 4 and the solutions of installing the bar magnets 7 on the rail bars 11 of the two side fence mechanisms 1 is selected, and of course, they may be installed at the same time.

In one embodiment, as shown in fig. 1-3, the vehicle bumper further comprises a vertical bumper bar 5 and a universal wheel 6, wherein the vertical bumper bar 5 is vertically fixed on the horizontal bumper bar 11, and the universal wheel 6 is arranged at the bottom of the vertical bumper bar 5. The vertical bar 5 is used to support the crosspiece 11, reduce the load of the rotation point between the crosspiece 11 and the fixed seat 12, and maintain the horizontal arrangement of the crosspiece 11. The universal wheel 6 is used for supporting and guiding the horizontal rotation of the crosspiece rod 11.

The utility model discloses when using, as shown in fig. 1-5, the staff rotates the crosspiece pole 11 of both sides in opposite directions for the straight locking plate 22 of the tip of crosspiece pole 11 is arranged in U-shaped locking plate 21 (promptly rail mechanism 1 reachs the latched position), is connected fixedly with a straight locking plate 22 with U-shaped locking plate 21 through the lockpin, and at this moment, the limit switch 13 of both sides senses crosspiece pole 11 respectively, send signal to P L C, and just the steerable bipyramid desiccator 3 of P L C starts up this moment, if remove the locking at rail mechanism 1, as long as one of them limit switch 13 signal disappears, P L C controls bipyramid desiccator 3 and forces to shut down immediately, and then protection staff's safety.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
