Technical Field

[0001] The invention belongs to the technical field related to loading at a discharge port, and in particular relates to an auxiliary early warning system for loading at a discharge port. Background Art

[0002] At present, when external vehicles are loading at the discharge port, it is often necessary to repeatedly move the vehicle to the best position for receiving the materials during the alignment process, especially at night when visibility is poor, which increases the difficulty of alignment and loading; after the alignment is completed, the material level cannot be observed during the receiving process due to fog, dust, night environment, height and other factors (due to the dust removal system, the discharge port is well sealed, and the camera and lighting system are installed inside for poor observation), and it is often difficult to coordinate the movement of the vehicle at the discharge port, which will cause the material to fall to the ground. After loading, the scattered materials under the material port need to be cleaned, which adds time for subsequent receiving vehicles and greatly reduces the discharge speed. Summary of the invention

[0003] Based on this, it is necessary to provide a discharge port loading auxiliary warning system to address the technical problems existing in the prior art.

[0004] A discharge port loading auxiliary warning system is used for loading transport vehicles at the discharge port;

[0005] It includes a first vehicle alignment rod, a second vehicle alignment rod, a signal light assembly, and a detection sensor assembly. The transport vehicle can determine the position of the discharge port through the first vehicle alignment rod, and can determine the tail position of the transport vehicle through the second vehicle alignment rod. The detection sensor assembly can detect the transport vehicle receiving materials from the discharge port and send the measured signal to the signal light assembly to make the signal light assembly emit lights of different colors.

[0009] In one embodiment, the detection sensor assembly includes a second material level detection sensor, which can detect whether the material level of the material located behind the discharge port on the transport vehicle exceeds the side guardrail of the transport vehicle, and the signal light assembly can receive the signal of the second material level detection sensor and turn off the red light.

[0010] In one embodiment, the detection sensor assembly includes a third material level detection sensor, which can detect whether the material level of the material in the position in front of the discharge port on the transport vehicle exceeds the side guardrail of the transport vehicle, and the signal light assembly can receive the signal of the third material level detection sensor and turn on the green light.

[0011] In one embodiment, the first material level detection sensor, the second material level detection sensor and the third material level detection sensor are all configured as mercury switches.

[0012] In one of the embodiments, the first material level detection sensor, the second material level detection sensor and the third material level detection sensor are arranged along the driving direction of the transport vehicle, and are all installed on the discharge port through a limiting fixing bracket.

[0013] In one of the embodiments, the detection sensor assembly further includes a discharge control sensor, and the discharge port can close the discharge through the discharge control sensor.

[0014] In one of the embodiments, the discharge control sensor is arranged perpendicular to the travel direction of the transport vehicle and is installed on the discharge port through a connecting bracket.

Specific embodiments

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0023] The discharge port loading auxiliary warning system for which protection is sought in the present invention is applied to the loading of a transport vehicle 200 at the discharge port 300 .

[0024] like Figure 1 , Figure 2 As shown, a discharge port loading auxiliary warning system provided by an embodiment of the present invention includes a first vehicle alignment rod 10, a second vehicle alignment rod 20, a signal light assembly 30, and a detection sensor assembly.

[0025] Among them, the transport vehicle 200 can determine the position of the discharge port 300 through the first vehicle alignment rod 10, and can determine the tail position of the transport vehicle 200 through the second vehicle alignment rod 20. That is to say, the transport vehicle 200 of this embodiment drives into the discharge port 300 in a reverse manner, and can use the rearview mirror or reflector of the transport vehicle 200 to observe the positions of the first vehicle alignment rod 10 and the second vehicle alignment rod 20 respectively to determine the position of the transport vehicle 200 driving into the discharge port 300, so that the transport vehicle 200 can accurately drive into the position where the discharge port 300 is located. It should be noted that the transport vehicle 200 uses the first vehicle alignment rod 10 and the second vehicle alignment rod 20 to determine the position between the transport vehicle 200 and the discharge port 300, which can be determined specifically by the experience of the driver of the transport vehicle 200, and will not be elaborated here.

[0026] Secondly, the detection sensor assembly of this embodiment can detect the material receiving of the transport vehicle 200 from the material discharge port 300, and send the detected signal to the signal light assembly 30, so that the signal light assembly 30 emits lights of different colors. The transport vehicle 200 can judge the situation of receiving the material from the material discharge port 300 according to the lights of different colors emitted by the signal light assembly 30 when working, and then combine the forward and backward movement of the transport vehicle 200 to achieve the transport vehicle 200 to complete one material receiving.

[0027] In this embodiment, the detection sensor assembly of this embodiment includes a vehicle sensing limit switch 101, which can sense the transport vehicle 200, and the signal light assembly can receive the signal of the vehicle sensing limit switch 101 and turn on the white light. It should be noted that the vehicle sensing limit switch 101 specifically detects whether the bucket 201 for receiving materials on the transport vehicle 200 is at the location of the discharge port 300. For this purpose, the vehicle sensing limit switch 101 can be set at the location of the discharge port 300, and it can be specifically judged by whether the vehicle sensing limit switch 101 senses the bucket 201 of the transport vehicle 200.

[0028] Specifically, the vehicle induction limit switch 101 of this embodiment is configured as a magnetic sensor, so that the vehicle induction limit switch 101 can be made of local materials, thereby reducing costs.

[0029] The detection sensor assembly of this embodiment includes a first material level detection sensor 102, which can detect whether the material level of the material located at the discharge port 300 on the transport vehicle 200 exceeds the side fence 202 of the transport vehicle 200, and the signal light assembly can receive the signal of the first material level detection sensor 102 and turn on the yellow light. In other words, during the loading process of the transport vehicle 200 of this embodiment, it can be judged whether the part of the bucket 201 on the transport vehicle 200 used for receiving materials exceeds the side fence 202 by observing whether the yellow light is observed, that is, it is judged whether the part on the bucket 201 has completed receiving materials.

[0030] The detection sensor assembly of this embodiment includes a second material level detection sensor 103, which can detect whether the material level of the material in the rear position of the discharge port 300 on the transport vehicle 200 exceeds the side fence 202 of the transport vehicle 200, and the signal light assembly can receive the signal of the second material level detection sensor 103 and turn off the red light. In other words, the red light in the signal light assembly is in a constant on state. When the red light goes out, it means that the material level of the material in the bucket 201 of the transport vehicle 200 in the rear position of the discharge port 300 has reached the loading standard, so that the transport vehicle 200 can move forward so that the unloaded part of the transport vehicle 200 can receive the material from the discharge port 300, which can be judged by observing whether the red light is lit again.

[0031] The detection sensor assembly of this embodiment includes a third material level detection sensor 104, which can detect whether the material in the material position in front of the discharge port 300 on the transport vehicle 200 exceeds the side fence 202 of the transport vehicle 200, and the signal light assembly can receive the signal of the third material level detection sensor 104 and turn on the green light. In other words, during the loading process of the transport vehicle 200 of this embodiment, it can be determined whether the front of the part of the bucket 201 on the transport vehicle 200 for receiving materials exceeds the side fence 202 by observing whether the green light is observed.

[0032] Specifically, the first material level detection sensor 102 , the second material level detection sensor 103 and the third material level detection sensor 104 of this embodiment are all configured as mercury switches to facilitate the production and preparation of the first material level detection sensor 102 , the second material level detection sensor 103 and the third material level detection sensor 104 .

[0033] The first material level detection sensor 102, the second material level detection sensor 103 and the third material level detection sensor 104 are arranged along the driving direction of the transport vehicle 200, and are all installed on the discharge port 300 through a limiting fixing bracket 301, so as to specifically realize the assembly of the first material level detection sensor 102, the second material level detection sensor 103 and the third material level detection sensor 104 in the auxiliary early warning system.

[0034] In summary, during the loading process of the transport vehicle 200 of this embodiment, when the transport vehicle 200 enters under the discharge port 300, the positions of the discharge port 300 and the transport vehicle 200 can be determined by observing the first vehicle alignment rod 10 through the vehicle rearview mirror. During the material receiving process, the forward position of the transport vehicle 200 can be determined by observing the changes in the indicator light assembly through the vehicle rearview mirror.

[0035] Specifically, when the green light is on, it means that the material height at the front end of the transport vehicle 200 has reached the top of the vehicle guardrail 202 of the transport vehicle 200. At this time, the red light goes out, and the transport vehicle 200 starts to move forward. When the red light comes on, it stops and waits for the red light to go out (the green light is always on, indicating that there is material at the front end, and the red light is off, indicating that the height of the material at the rear is not enough. The vehicle can be controlled to receive materials according to the red light going off and on, so as to ensure the height of the vehicle loading and reduce secondary material replenishment). When the yellow light is on, it means that the material level has exceeded the position of the vehicle guardrail 202, and the discharge port 30 0 Close the discharge. If you need to continue discharging, you need to move the transport vehicle 200 forward until the yellow light goes out, and then start the discharge port 300 to continue discharging. The position information of the transport vehicle 200 can be obtained by observing the white light. The white light on indicates that the transport vehicle 200 is in front of the limit. When the transport vehicle 200 drives to the tail, it is difficult for the driver to judge the tail position. The second vehicle alignment rod 20 and the white light can be observed to control the vehicle. When the vehicle sensing limit switch 101 cannot sense the transport vehicle 200, the white light goes out, indicating that it has reached the tail, and the discharge port 300 is closed to discharge. It should be noted that the signal light assembly can be specifically integrated on the second vehicle alignment rod 20, and the correspondence between the white light, yellow light, red light and green light on the signal light assembly and the detection sensor assembly can be replaced according to the needs of use or replaced by other lights of different colors, which will not be elaborated here.

[0036] As a preferred embodiment of the present invention, the detection sensor assembly of the present invention also includes a discharge control sensor 105, and the discharge port 300 can close the discharge through the discharge control sensor 105, so that when the auxiliary warning system is working, it can utilize the signal detection of the discharge control sensor 105 to realize the automatic closing of the discharge port 300.

[0037] The discharge control sensor 105 is arranged perpendicular to the travel direction of the transport vehicle 200 , and is installed on the discharge port 300 through a connecting bracket 302 .

[0038] like Figure 3 As shown, the circuit control system corresponding to the discharge port loading auxiliary warning system of this embodiment is as follows: adding SQ1 (first material level detection sensor 102), KA1 (first relay), SQ2 (second material level detection sensor 103), KA2 (second relay), SQ3 (third material level detection sensor 104), KA3 (third relay), SQ4 (third material level detection sensor 104), KA4 (fourth relay), SQ5 (vehicle induction limit switch 101), SQ6 (vehicle induction limit switch 101) green light (check the material level in the front side), red light (check the material level in the rear side), yellow light (the material will light up when it exceeds the side of the vehicle, and then automatically shut down the system to discharge the material), white light (used to check the vehicle position, through two limit controls, the white light will light up after the vehicle is sensed, and the white light will go out after the vehicle drives out, the limit principle; the limit is closed after the iron is sensed) when in use, press the SB1 button to jog and open the material discharge port, add KA1 (the first relay normally closed point) and KA2 (the second relay normally closed point) to the original system circuit during operation, so that the material touches the first material level detection sensor 102 and the second material level detection sensor 103 at the same time to disconnect the line (the purpose is to realize the safety interlocking circuit with KM2), and then in the original system KM2 KA1 (the normally open point of the first relay) and KA2 (the normally open point of the second relay) are incorporated into the circuit (closing the discharge port) to achieve the closing circuit when the material touches the first material level detection sensor 102 and the second material level detection sensor 103 at the same time (the purpose is to achieve the discharge port beyond the compartment electrical system to force it to close). After forced closure, the vehicle can be moved to restore the limit to normal, and the SB1 button can be pressed again to open the discharge port (under normal circumstances, observe the change of the red light through the rearview mirror and adjust the vehicle's forward movement in time to avoid the material triggering the first material level detection sensor 102 and the second material level detection sensor 103 on the upper left and right sides of the vehicle). After closing, the entire system is protected to achieve safe, efficient and clean loading. The signal light display is as follows Figure 2As shown, green light: when KA3 (the third relay coil and the normally open point) closes the third relay normally open point through SQ3 (the third material level detection sensor 104), the green light will be on; red light: when KA4 (the fourth relay coil and the normally closed point) closes the third relay normally closed point through SQ4 (the third material level detection sensor 104), the red light will be off; yellow light: when KA1 (the first relay coil and the normally open point of the relay) and KA2 (the second relay coil and the normally open point of the relay) are closed through SQ1 (the first material level detection sensor 102) and SQ2 (the second material level detection sensor 103), the yellow light will be on; white light: when SQ5 (the vehicle sensing limit switch 101 takes the open point) and SQ6 (the vehicle sensing limit switch 101 takes the open point) are closed at the same time, the white light will be on. Note: As Figure 2 Shown are SB1 (discharging port opening start button), SB2 (discharging port closing start button), SB3 (start button), FU1 and FU2 (control system fuses), QF (control auxiliary system circuit breaker, when the added limit and electrical components fail and cannot be operated, the circuit breaker can be disconnected to restore the original system use, and the circuit breaker can be connected again after repair, using the device auxiliary system), KM1 (discharging port motor opening contactor coil and contactor normally closed point) KM2 (discharging port motor closing contactor coil and contactor normally closed, normally closed points), FR (thermal relay normally closed point).

[0039] In summary, the discharge port loading auxiliary warning system of the present invention, through reasonable structural settings, enables the signal light assembly to emit lights of different colors according to different signals measured by the detection sensor assembly when the discharge port loading auxiliary warning system is working, so as to assist the transport vehicle in loading at the discharge port position, so as to facilitate the transport vehicle to complete the loading and avoid the transport vehicle from dropping materials in the process of receiving materials. It has the effect of reducing the borrowing time of the transport vehicle when receiving materials and increasing the discharge speed of the discharge port.
