In the process of construction, conveying devices are often needed to transport some construction materials. For example, a material conveying device for construction is proposed in patent announcement number CN118205891B.

The upper end of the rotating rod 18 extends out of the cylinder 17 and is fixedly connected to the anti-skid strip 10. The lower inner wall of the cylinder 17 is fixedly connected to an adjusting motor 19. The output end of the adjusting motor 19 is transmission-connected to the rotating rod 18 through a gear ring transmission assembly. The left and rear inner walls of the cylinder 17 are fixedly connected to a locking frame 20. The lower side wall of the locking frame 20 is fixedly connected to a locking electric push rod 21.

[0040] The right side wall of the dividing plate 9 is fixedly connected to the second electric push rod 38 through a bracket, and the moving end of the second electric push rod 38 is fixedly connected to the detection box 39 through a pressure sensor. The right inner wall of the detection box 39 is fixedly connected to the detection block 40 through a spring, and the lower side wall of the detection block 40 is fixedly connected to a guide plate 41.

[0042] A trigger switch 49 is fixedly connected to the inner wall of the rear side of the control box 111. The trigger switch 49 is electrically connected to the PLC controller 3. After the sliding seat 13 moves back to the initial position, the micro electric push rod 15 can be controlled by the trigger switch 49 to work, and the positioning pin 16 is driven by the micro electric push rod 15 to fix the sliding seat 13.

[0043] The rear inner wall of the conveying frame 4 is fixedly connected to a laser generator 50 through a bracket, and the side wall of each cylinder 17 is fixedly connected to a laser receiver 51 that matches the laser generator 50. The laser receiver 51 is electrically connected to the PLC controller 3. When the anti-slip strip 10 approaches the dividing plate 9, the anti-slip strip 10 can be released.

[0044] The operating principle of the present invention is now described as follows: the hydraulic cylinder 37 is electrically connected to the external control button, and the hydraulic cylinder 37 can be controlled to work through the external control button. According to the use requirements, the hydraulic cylinder 37 is used to adjust the inclination angle of the conveying frame 4 and the conveyor belt 6. The operator controls the hydraulic cylinder 37 to work through the external control button, and the hydraulic cylinder 37 drives the adjustment rod 35 to rotate to the left, and the upper end of the adjustment rod 35 drives the adjustment slide 33 to slide on the surface of the adjustment slide rail 32, so that the right end of the conveying frame 4 can rotate counterclockwise along the hinge of the vertical rod 311 and the adjustment frame 312. When the conveying frame 4 is adjusted to a certain angle according to the use requirements;

[0045] When the conveying frame 4 is rotating, the conveying frame 4 will drive the adjustment disk 271 to rotate together, and the adjustment disk 271 will drive the arc-shaped conductive plate 30 to rotate together, and the conductive block 29 and the vertical rod 28 will always remain motionless in the vertical direction under the action of gravity. When the adjustment angle of the conveying frame 4 exceeds twenty degrees, the adjustment disk 271 will drive the arc-shaped conductive plate 30 to contact the conductive block 29, and the conductive block 29 will be electrically connected to the external power supply, and the arc-shaped conductive plate 30 will be electrically connected to the PLC controller 3. When the conductive block 29 and the arc-shaped conductive plate 30 are in contact, an electrical signal will be transmitted to the PLC controller 3. After receiving the electrical signal, the PLC controller 3 will immediately The locking electric push rod 21 on the left side of the control cylinder 17 drives the locking pin 22 to move downward, so that the locking pin 22 on the left side is separated from the locking hole on the surface of the ring 23, and then the PLC controller 3 controls the adjusting motor 19 to work clockwise, and the adjusting motor 19 is connected to the rotating rod 18 through the gear ring transmission assembly (the output end of the adjusting motor 19 is connected with a transmission gear, and the rod wall fixing sleeve of the rotating rod 18 is provided with a transmission ring meshing with the transmission gear). The adjusting motor 19 will drive the rotating rod 18 and the anti-skid strip 10 at the upper end to rotate together, so that the anti-skid strip 10 rotates to the top of the conveyor belt 6, and the rotating rod 18 will drive the ring 23 to rotate together during the rotation process. When the second arc seat 26 on the surface of the ring 23 rotates to the rear side, the second arc seat 26 will squeeze the first arc seat 25 on the rear side, and the first arc seat 25 on the rear side will squeeze the squeezing switch 24 on the rear side, and the squeezing switch 24 on the rear side will control the adjusting motor 19 to stop working (the adjusting motor 19 is a non-brake motor) through the PLC controller 3, and control the locking electric push rod 21 on the rear side to drive the locking pin 22 on the rear side to move upward, so that the locking pin 22 on the rear side is inserted into the locking hole on the surface of the ring 23, so that the rotating rod 18 can be locked, and the front end of the anti-slip strip 10 can be locked. At this time, the anti-slip strip 10 will be in a vertical state with the conveyor belt 6, and the PLC controller The controller 3 will also control multiple positioning electric push rods 46 to work simultaneously. The positioning electric push rod 46 will drive the positioning pin 47 to insert into the positioning groove on the surface of the positioning seat 48, so as to fix the rear end of the anti-skid strip 10 (the reverse operation can restore the anti-skid strip 10 to the initial horizontal placement). The anti-skid strip 10 is used to transport the material on the surface of the conveyor belt 6 to avoid the material on the surface of the conveyor belt 6 from slipping, thereby ensuring the conveying performance of the conveyor belt 6. When the inclination angle of the conveyor belt 6 is less than 20 degrees, the anti-skid strip 10 will not move to the surface of the conveyor belt 6, thereby avoiding the problem that the anti-skid strip 10 is in contact with the material for a long time, which will shorten the service life of the anti-skid strip 10 due to wear.

[0046] When it is necessary to perform fixed-point material distribution on the conveying device, the operator can control the first electric push rod 8 through the PLC controller 3 to drive the material distribution plate 9 to move downward, so that the material distribution plate 9 contacts the surface of the conveyor belt 6. At the same time, the PLC controller 3 will also control the laser generator 50 located on the left side of the material distribution plate 9 to be powered on. When the conveyor belt 6 and the anti-slip strip 10 transport the material driven by the conveyor roller 5, when the laser receiver 51 on the surface of the cylinder 17 passes through the laser generator 50, the laser generator 50 will transmit an electrical signal to the PLC controller 3, and the PLC controller 3 will transmit an electrical signal to the laser generator 50. After receiving the electrical signal, the PLC controller 3 will immediately control the positioning electric push rod 46 to drive the positioning pin 47 to retract to the initial state, and control the rear locking electric push rod 21 to drive the rear locking pin 22 to retract to the initial state, that is, release the fixation of the anti-slip strip 10 and the rotating rod 18. At the same time, the PLC controller 3 will also control the micro electric push rods 15 on the upper and lower sides of the control box 111 to drive the positioning pin 16 to retract, release the mutual fixation between the sliding seat 13 and the control box 111, and when the conveyor belt 6 drives the anti-slip strip 10 to move and contact the dividing plate 9, After the contact, under the action of the top thrust of the material dividing plate 9, the anti-skid strip 10 will rotate forward, causing the material on the surface of the anti-skid strip 10 to fall to the bottom of the conveying device (the surface of the conveying frame 4 is provided with a material guide plate to prevent the material from falling into the conveying frame 4), and when the anti-skid strip 10 passes through the material dividing plate 9, the material dividing plate 9 will squeeze the anti-skid strip 10 to the front side, so that the anti-skid strip 10 drives the bending rod 12 and the sliding seat 13 to move forward a short distance through the rotating rod 18 and the cylinder 17. When the anti-skid strip 10 and the material dividing plate 9 are separated, the sliding seat 13 will Move backward and squeeze the trigger switch 49. After the trigger switch 49 is squeezed again, an electrical signal will be transmitted to the PLC controller 3, and the PLC controller 3 will control the micro electric push rods 15 on the upper and lower sides to work, so that the micro electric push rods 15 drive the positioning pins 16 to insert into the positioning grooves inside the control box 111, so as to fix the bent rod 12. At the same time, the PLC controller 3 will repeat the above steps to control the adjustment motor 19 to work, so as to adjust the anti-slip strip 10 to continue to rotate to a position perpendicular to the conveyor belt 6, so as to transport the material;

[0047] While the material on the surface of the conveyor belt 6 is cleaned off by the dividing plate 9, the PLC controller 3 will also control the second electric push rod 38 to work. The second electric push rod 38 will drive the detection box 39 and the friction block 42 to move downward together through the pressure sensor. When the friction block 42 contacts the conveyor belt 6 (the material on the surface of the conveyor belt 6 is cleaned off), an interaction force will be generated. When the pressure sensor detects that the interaction force reaches 10N, the second electric push rod 38 will be controlled to stop working through the PLC controller 3. At this time, a friction force will be generated between the friction block 42 and the conveyor belt 6. When the wear degree of the conveyor belt 6 is small, the anti-skid pattern on the surface of the conveyor belt 6 is relatively intact, and the friction force between the conveyor belt 6 and the friction block 42 is relatively large. Under the action of the large friction force, the friction block 42 will pass through the positioning pin 47. Drive the detection block 40 and the trigger block 43 to move a long distance to the right, so that the trigger block 43 and the trigger plate 44 are in contact, the trigger block 43 is electrically connected to the external power supply, and the trigger plate 44 is electrically connected to the PLC controller 3. When the PLC controller 3 receives the electrical signal transmitted by the trigger plate 44 within five seconds of the second electric push rod 38 working, it means that the conveyor belt 6 is less worn. On the contrary, when the PLC controller 3 does not receive the electrical signal transmitted by the trigger plate 44 within five seconds of the second electric push rod 38 working, it means that the conveyor belt 6 is more worn. When the conveyor belt 6 tilts at a smaller angle, slippage may occur. It is difficult for the operator to distinguish the degree of wear of the conveyor belt 6 with the naked eye. The PLC controller 3 will control the internal buzzer to work, reminding the operator to replace the conveyor belt 6 as soon as possible.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
