Description

Technical Field

[0001] The utility model belongs to the field of metallurgical engineering equipment, and specifically relates to an automatic slag transport device. Background Art

[0002] In the metallurgical process, impurities will be produced after the material is melted in the melting furnace. In order to prevent the waste slag from clogging and obstructing the equipment and ensure the normal operation of the production equipment, the project needs to use a slag transport device to transport the waste slag to other areas.

[0003] The utility model with publication number CN208615951U discloses a slag transport vehicle and track, including a slag transport vehicle, track and dump bucket. The utility model uses manpower to push the slag transport vehicle to move on the track, and then unloads by flipping the dump bucket. However, this method requires manpower to maintain, has low work efficiency, and the entire operation process is highly dangerous, with the risk of safety accidents; the invention patent application with publication number CN112918497A discloses a track-type slag transport device for use in tunnels, including a vehicle body assembly, a flip assembly and a discharge assembly. The invention uses a motor-driven method to make the slag transport device run on the track, and then the waste slag is discharged through the cooperation of the flip assembly and the discharge assembly, but the device still requires manual operation by workers, such as the waste slag transportation in the field of metallurgical engineering, which has a greater safety risk. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides an automatic slag transport device, which is used for automated and streamlined waste slag transport operations between loading stations and unloading stations, thereby reducing the accidental risks that may occur in manual operations.

[0005] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical solutions: an automatic slag transport device, comprising: a guide rail, a sensing element, a traveling mechanism and a slag bucket; the guide rail passes through a loading station and an unloading station; the traveling mechanism is arranged on the guide rail and moves along the guide rail between the loading station and the unloading station; the slag bucket is installed on the traveling mechanism; a triggering member is installed on the traveling mechanism; a sensing element is provided at the loading station and on the movement path of the triggering member, and a sensing element is also provided at the unloading station and on the movement path of the triggering member; when the traveling mechanism moves to the loading station or the unloading station, the triggering member touches the sensing element, and the sensing element sends a signal for controlling the movement state of the traveling mechanism.

[0006] Furthermore, when the triggering member touches the sensing element, the sensing element sends a signal for controlling the walking mechanism to stop.

[0007] The above-mentioned automatic slag transport device can be used for waste slag transportation in scenes such as metal smelting workshops, metal processing plants and welding workstations, and transfers waste slag between loading stations and unloading stations: at the loading station, the waste slag to be transferred is loaded into the slag bucket of the slag transport device, and then the slag transport device transports the waste slag to the unloading station for unloading. When the walking mechanism moves to the loading station, the trigger touches the sensing element of the loading station, triggering the walking mechanism to stop moving at the loading station; when the walking mechanism moves to the unloading station, the trigger touches the sensing element of the unloading station, triggering the walking mechanism to stop moving at the unloading station. The sensing element enables the walking mechanism to accurately stop at a predetermined position, such as stopping directly below the slag discharge port of the loading station, to prevent the waste slag from falling to the outside of the slag bucket when the furnace body is discharged, and at the same time facilitates automated and process-based operations.

[0008] In addition, a remote control module can be preset in the traveling mechanism. When waste slag needs to be collected, a signal is sent through the remote control box to make the traveling mechanism move toward the loading station, and the traveling mechanism stops at the loading station after moving to the trigger sensing element; when waste slag needs to be unloaded, a signal is sent through the remote control box to make the traveling mechanism move toward the unloading station, and the traveling mechanism stops at the unloading station after moving to the trigger sensing element. Such operation can increase the safety of slag transportation, and the operator only needs to remotely control the equipment in a safe position to reduce the risk of accidents.

[0009] Furthermore, the above-mentioned automatic slag transport device is provided with a first sensing area and a second sensing area in the loading station and along the movement path of the trigger member, and sensing elements are provided in the first sensing area and the second sensing area; and a third sensing area and a fourth sensing area are provided in the unloading station and along the movement path of the trigger member, and sensing elements are provided in the third sensing area and the fourth sensing area.

[0010] In the loading station, two sensing areas are provided along the movement path of the triggering member, one is located at the proximal end of the loading station, and the other is located at the distal end of the loading station; the former sensing area is used to monitor the position of the slag transport device in normal operation, and is used to trigger the travel mechanism to stop moving at the loading station; the latter sensing area is used to monitor the area at the end of the loading station, especially when the travel mechanism does not stop normally in the previous sensing area, it can trigger the safe stop of the slag transport device. Similarly, two sensing areas are also provided in the unloading station, which are used to trigger the travel mechanism to stop normally at the correct working position and to ensure that the travel mechanism does not accidentally run out of the guide rail. By setting two sensing areas at one station, it is possible to ensure that the slag transport device stops at the correct working position and prevent the slag transport device from accidentally running out of the guide rail, thereby reducing the risk of accidents during operation.

[0011] Furthermore, in the above-mentioned automatic slag transport device, in the loading station, two sensing elements are vertically arranged in the first sensing area; in the unloading station, two sensing elements are vertically arranged in the third sensing area; the first sensing area is closer to the loading station than the second sensing area, and the third sensing area is closer to the unloading station than the fourth sensing area.

[0012] By setting two vertically arranged sensing elements, when one of the sensing elements fails, the other sensing element can still work normally, which can trigger the travel mechanism to stop moving, ensure the reliability of the sensing elements of the loading and unloading stations, ensure that the travel mechanism can stop moving at one time, and improve the stability and reliability of the slag transport device. In addition, if the status of the two sensing elements is inconsistent, it can be judged that at least one of the sensing elements cannot work normally, so that the fault can be discovered and repaired in time.

[0013] Furthermore, in the above-mentioned automatic slag transport device, the trigger member has two slope contact sensing elements forming an obtuse angle, which are recorded as the first slope and the second slope; with the movement direction of the walking mechanism as a reference, the first slope and the second slope face opposite walking directions.

[0014] No matter the walking mechanism moves forward or backward, since the first slope surface and the second slope surface are at an angle to the direction directly facing the sensing element in opposite directions, after the sensing element contacts the slope surface, the sensing element can rotate under the squeezing action of the slope surface and slide along the slope surface, thereby reducing the impact when the triggering member contacts the sensing element and extending the service life of the sensing element.

[0015] Furthermore, in the above-mentioned automatic slag transport device, the traveling mechanism includes a chassis, a support platform and a group of screws; the chassis is at the bottom of the traveling mechanism, the lower end of the screw is fixed on the chassis, the upper end of the screw passes through the support platform, and an upper adjusting nut and a lower adjusting nut are threadedly provided at the top of the screw to clamp the support platform from the upper and lower sides.

[0016] The height of the support table can be adjusted by adjusting the upper and lower adjustment nuts. This design facilitates assembly and commissioning during initial installation. Operators can easily adjust the height of the support table according to specific needs, ensuring that the travel mechanism has met the predetermined height standard, reducing the need for subsequent adjustments.

[0017] Furthermore, in the above-mentioned automatic slag transport device, the traveling mechanism includes a limiter; the limiter is installed on the support platform, and the slag bucket is placed in the area defined by the limiter.

[0018] The limiter is used to fix the slag bucket so that the slag bucket falls within the area defined by the limiter. The existence of the limiter helps to maintain the stability of the slag bucket during operation and prevent the slag bucket from shifting.

[0019] Furthermore, the above-mentioned automatic slag transport device is provided with a limit member at each of the front and rear ends of the traveling mechanism, and each limit member includes a transverse limit portion and a longitudinal limit portion; the transverse limit portion is perpendicular to the moving direction of the traveling mechanism; the longitudinal limit portion is perpendicular to the transverse limit portion and is installed at both ends of the transverse limit portion.

[0020] The transverse limiting part and the longitudinal limiting part fix the slag bucket from multiple angles, so that the slag bucket and the traveling mechanism are tightly fixed, the shaking of the slag bucket is reduced, and the stability of the slag transport device and the reliability of operation are improved.

[0021] Furthermore, in the above-mentioned automatic slag transport device, a driving wheel, a driven wheel and a motor are installed on the chassis of the walking mechanism; the motor is power-connected to the driving wheel, and is preferably a brake motor with a brake; the automatic slag transport device also includes a control unit, and the sensing element and the motor are both signal-connected to the control unit; when the control unit receives a signal that the sensing element of the loading station or the unloading station is triggered, the motor is controlled to stop.

[0022] The motor drives the driving wheel to move or stop the traveling mechanism. When the trigger touches the sensing element, the sensing element feeds back a signal to the control unit that the traveling mechanism has reached the specified position, and the control unit controls the motor to stop, so that the traveling mechanism stops. Through the linkage between the sensing element, the motor and the control unit, the stopping position of the traveling mechanism can be effectively controlled, providing an accurate and safe operating environment, while achieving the effect that the traveling mechanism can automatically stop after moving to the specified position, realizing the automatic control of the slag transport device.

[0023] Furthermore, in the above-mentioned automatic slag transport device, the traveling mechanism also includes a slag removal device; the slag removal device is installed on the left and right sides of the chassis; the slag removal device includes an adjustment bracket installed on the chassis and a scraper installed on the adjustment bracket; the lower part of the scraper has an opening for the guide rail to be embedded.

[0024] The height of the slag removal device can be adjusted by the adjustment bracket installed on the chassis; the opening at the bottom of the scraper of the slag removal device fits with the guide rail. As the traveling mechanism moves, the scraper will move along the surface of the guide rail to remove the fine slag attached to the guide rail, thereby avoiding bumps or additional friction during the movement of the traveling mechanism, ensuring that the traveling mechanism is unobstructed during movement, improving operating efficiency and stability, and reducing unnecessary pauses or failures caused by fine impurities.

[0025] Furthermore, in the above-mentioned automatic slag transport device, the slag bucket includes a bucket bin and a plurality of reinforcements; the reinforcement ribs are fixed to the outer side of the bucket bin to form a grid-like envelope structure.

[0026] The presence of reinforcing ribs can effectively increase the overall structural strength of the bucket, reduce deformation and vibration, improve the bucket's ability to withstand thermal expansion, and ensure that the bucket maintains a stable shape during operation or loading.

[0027] Furthermore, in the above-mentioned automatic slag transport device, the slag bucket also includes a forklift hole; the forklift hole is located at the bottom of the slag bucket and passes through the slag bucket horizontally.

[0028] The forklift hole is a working space reserved for forklifts. When replacing the slag bucket, the forklift only needs to pass the forklift arm sideways through the forklift hole to remove the slag bucket from the traveling mechanism. The method of directly replacing the slag bucket by forklift reduces the time required for the slag transportation process and increases the efficiency of the slag transportation process.

[0029] In addition, when multiple sensing areas are provided in the loading station and along the motion path of the triggering member, and sensing elements are provided in the multiple sensing areas, the control unit receives a signal from the sensing element, which is recorded as an input signal; the control unit sends a signal to control the motion state of the walking mechanism, which is recorded as an output signal. The control unit has a preset mapping relationship between the input signal and the output signal, and sends a corresponding output signal to the walking mechanism according to the mapping relationship and the input signal from the sensing element, thereby controlling the motion state of the walking mechanism.

[0030] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the automatic slag transport device of the utility model monitors the position of the slag transport device through the cooperation of the trigger, the sensing element and the remote control module, and can accurately control the slag transport device to stop at the designated work station; it can realize continuous waste slag transportation and processing through mechanized operation, improve production efficiency, and at the same time reduce the demand for manpower and reduce the risk of manual transportation of waste slag; and a safety sensing area is provided to prevent the slag transport device from rushing out of the track uncontrollably, thereby reducing possible safety hazards during waste slag transportation.

DETAILED DESCRIPTION

[0042] Example 1

[0043] like Figure 1 An automatic slag transport device shown can be used for waste slag transportation in scenes such as metal smelting workshops, metal processing plants and welding workstations, and transfers waste slag between loading stations and unloading stations. At the loading station, the waste slag to be transferred is loaded into the slag transport device, and then the slag transport device transports the waste slag to the unloading station for unloading.

[0044] like Figure 1 As shown, the slag transport device of this embodiment includes: a guide rail 1, a sensing element 2, a traveling mechanism 3, a slag bucket 4 and a trigger member 31; the guide rail 1 passes through a loading station and an unloading station; the traveling mechanism 3 is arranged on the guide rail 1, and moves along the guide rail 1 between the loading station and the unloading station; the slag bucket 4 is installed on the traveling mechanism 3; a trigger member 31 is installed on the traveling mechanism 3; a sensing element 2 is provided at the loading station and on the movement path of the trigger member 31, and a sensing element 2 is also provided at the unloading station and on the movement path of the trigger member 31.

[0045] When the traveling mechanism 3 moves to the loading station, the triggering member 31 touches the sensing element 2 of the loading station, triggering the traveling mechanism 3 to stop at the loading station; when the traveling mechanism 3 moves to the unloading station, the triggering member 31 touches the sensing element 2 of the unloading station, triggering the traveling mechanism 3 to stop at the unloading station. Through the two sensing elements 2, the moving range of the traveling mechanism 3 is limited between the loading station and the unloading station.

[0046] like Figure 2As shown, the traveling mechanism 3 includes a chassis 32, a support platform 33 and a group of screw rods 34; the chassis 32 is at the bottom of the traveling mechanism 3; the lower end of the screw rod 34 is fixed on the chassis 32, the upper end of the screw rod 34 passes through the support platform 33, and an upper adjusting nut and a lower adjusting nut are threadedly provided at the top of the screw rod 34 to clamp the support platform 33 from the upper and lower sides.

[0047] By adjusting the upper adjustment nut and the lower adjustment nut, the height of the support platform 33 can be adjusted. During the initial installation, the height of the support platform 33 can be adjusted according to the needs of the metallurgical workshop so that the walking mechanism 3 meets the predetermined height standard, reducing the need for subsequent adjustments.

[0048] like Figure 2 As shown, the traveling mechanism 3 further includes two limiting members 35 ; the limiting members 35 are installed on the supporting platform 33 , and the slag bucket 4 is placed in the area defined by the limiting members 35 .

[0049] The stopper 35 is used to fix the slag bucket 4 so that the slag bucket 4 falls within the area defined by the stopper 35. The stopper 35 is engaged with the slag bucket 4 so that the slag bucket 4 is fixed on the traveling mechanism 3, thereby reducing the shaking of the slag bucket 4 during movement and preventing the slag bucket 4 from deflecting.

[0050] like Figure 2 As shown, the traveling mechanism 3 further includes a driving wheel 36, a driven wheel 37, and a motor 38; the motor 38 is connected to the driving wheel 36 by power, and the driving wheel 36 is driven by the motor 38, so that the traveling mechanism 3 moves or stops.

[0051] The automatic slag transport device in this embodiment also includes a control unit and a remote control box. The sensing element 2, the motor 38, and the remote control box are all connected to the control unit by signals, and the worker operates the remote control box in a safe area.

[0052] When the control unit receives the signal from the remote control box to move the slag transport device to the loading station, the control unit controls the motor 38 to rotate forward, so that the travel mechanism 3 moves to the loading station. When the travel mechanism 3 moves to the loading station, the trigger 31 touches the sensor element 2 of the loading station. The sensor element 2 rotates under the squeezing action of the trigger 31, and at this time, the sensor element 2 feedbacks the signal that the travel mechanism 3 has reached the loading station to the control unit. Based on the feedback signal of the sensor element 2, the control unit controls the motor 38 to stop and brake, so that the travel mechanism 3 stops at the loading station; similarly, when the control unit receives the signal from the remote control box to move the slag transport device to the unloading station, the control unit controls the motor 38 to reverse, so that the travel mechanism 3 moves to the unloading station. When the travel mechanism 3 moves to the unloading station, the trigger 31 touches the sensor element 2 of the unloading station. The sensor element 2 rotates under the squeezing action of the trigger 31, and at this time, the sensor element 2 feedbacks the signal that the travel mechanism 3 has reached the unloading station to the control unit. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the traveling mechanism 3 stops at the unloading station.

[0053] Example 2

[0054] like Figure 3 An automatic slag transport device shown can be used for waste slag transportation in scenes such as metal smelting workshops, metal processing plants and welding workstations, and transfers waste slag between loading stations and unloading stations. At the loading station, the waste slag to be transferred is loaded into the slag transport device, and then the slag transport device transports the waste slag to the unloading station for unloading.

[0055] like Figure 3 As shown, the slag transport device of this embodiment includes: a guide rail 1, a sensing element 2, a traveling mechanism 3, a slag bucket 4 and a trigger member 31; the guide rail 1 passes through a loading station and an unloading station; the traveling mechanism 3 is arranged on the guide rail 1, and moves along the guide rail 1 between the loading station and the unloading station; the slag bucket 4 is installed on the traveling mechanism 3; a trigger member 31 is installed on the traveling mechanism 3; a sensing element 2 is provided at the loading station and on the movement path of the trigger member 31, and a sensing element 2 is also provided at the unloading station and on the movement path of the trigger member 31.

[0056] When the traveling mechanism 3 moves to the loading station, the triggering member 31 touches the sensing element 2 of the loading station, triggering the traveling mechanism 3 to stop at the loading station; when the traveling mechanism 3 moves to the unloading station, the triggering member 31 touches the sensing element 2 of the unloading station, triggering the traveling mechanism 3 to stop at the unloading station. Through the two sensing elements 2, the moving range of the traveling mechanism 3 is limited between the loading station and the unloading station.

[0057] In this embodiment, a first sensing area and a second sensing area are provided in the loading station and along the movement path of the trigger member 31, and sensing elements 2 are provided in the first sensing area and the second sensing area; a third sensing area and a fourth sensing area are provided in the unloading station and along the movement path of the trigger member 31, and sensing elements 2 are provided in the third sensing area and the fourth sensing area.

[0058] The first and third sensing areas are close to the areas where the slag transport device needs to collect or unload waste slag, so that the traveling mechanism 3 can accurately stop at the corresponding station when it reaches the designated loading station or unloading station. The second and fourth sensing areas are to ensure that the traveling mechanism 3 will eventually stop safely on the track and will not run off the track when the sensing element 2 in the above sensing area fails.

[0059] like Figure 4 As shown, two sensing elements 2 are vertically arranged in the first sensing area in the loading station; similarly, two sensing elements 2 are vertically arranged in the third sensing area in the unloading station; the first sensing area is closer to the loading station than the second sensing area, and the third sensing area is closer to the unloading station than the fourth sensing area.

[0060] Two vertically arranged sensing elements 2 are arranged in one sensing area, so that when the traveling mechanism 3 moves to the loading station or the unloading station, the triggering member 31 touches the two sensing elements 2 at the same time and triggers the traveling mechanism 3 to stop moving. In addition, if the information fed back by the two sensing elements 2 is inconsistent, it can be determined that at least one of the sensing elements 2 is faulty, and the staff will come forward to check and repair it later.

[0061] like Figure 5 As shown, the trigger member 31 has two slopes forming an obtuse angle to contact the sensing element 2, which are marked as a first slope 311 and a second slope 312; with reference to the movement direction of the walking mechanism 3, the first slope 311 and the second slope 312 face opposite walking directions.

[0062] Whether the walking mechanism 3 moves forward or backward, since the first slope 311 and the second slope 312 are at an angle to the direction facing the sensing element 2 in opposite directions, after the sensing element 2 contacts the slope, the sensing element 2 can rotate under the squeezing action of the slope and slide along the slope.

[0063] like Figure 6 As shown, the traveling mechanism 3 includes a chassis 32, a support platform 33 and a group of screw rods 34; the chassis 32 is at the bottom of the traveling mechanism 3; the lower end of the screw rod 34 is fixed on the chassis 32, the upper end of the screw rod 34 passes through the support platform 33, and an upper adjusting nut and a lower adjusting nut are threadedly provided at the top of the screw rod 34 to clamp the support platform 33 from the upper and lower sides.

[0064] By adjusting the upper adjustment nut and the lower adjustment nut, the height of the support platform 33 can be adjusted. During the initial installation, the height of the support platform 33 can be adjusted according to the needs of the metallurgical workshop so that the walking mechanism 3 meets the predetermined height standard, reducing the need for subsequent adjustments.

[0065] like Figure 6 As shown, the traveling mechanism 3 further includes a driving wheel 36, a driven wheel 37, and a motor 38; the motor 38 is connected to the driving wheel 36 by power, and the driving wheel 36 is driven by the motor 38, so that the traveling mechanism 3 moves or stops.

[0066] The automatic slag transport device in this embodiment also includes a control unit and a remote control box. The sensing element 2, the motor 38, and the remote control box are all connected to the control unit by signals, and the worker operates the remote control box in a safe area.

[0067] When the control unit receives the signal from the remote control box to move the slag transport device to the loading station, the control unit controls the motor 38 to rotate forward, so that the travel mechanism 3 moves to the loading station. When the travel mechanism 3 moves to the loading station, the first slope 311 of the trigger member 31 touches the sensor element 2 of the loading station. The sensor element 2 rotates under the squeezing action of the first slope 311 and slides along the slope. At this time, the sensor element 2 feedbacks the signal that the travel mechanism 3 has reached the loading station to the control unit. Based on the feedback signal of the sensor element 2, the control unit controls the motor 38 to stop and brake, so that the travel mechanism 3 stops at the loading station; similarly, when the control unit receives the signal from the remote control box to move the slag transport device to the unloading station, the control unit controls the motor 38 to reverse, so that the travel mechanism 3 moves to the unloading station. When the travel mechanism 3 moves to the unloading station, the second slope 312 of the trigger member 31 touches the sensor element 2 of the unloading station. The sensor element 2 rotates under the squeezing action of the second slope 312 and slides along the slope. At this time, the sensor element 2 feedbacks the signal that the travel mechanism 3 has reached the unloading station to the control unit. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the traveling mechanism 3 stops at the unloading station.

[0068] like Figure 6 As shown, the traveling mechanism 3 further includes two limiting members 35 ; the limiting members 35 are installed on the supporting platform 33 , and the slag bucket 4 is placed in the area defined by the limiting members 35 .

[0069] The stopper 35 is used to fix the slag bucket 4 so that the slag bucket 4 falls within the area defined by the stopper 35. The stopper 35 is engaged with the slag bucket 4 so that the slag bucket 4 is fixed on the traveling mechanism 3, thereby reducing the shaking of the slag bucket 4 during movement and preventing the slag bucket 4 from deflecting.

[0070] like Figure 7As shown, each limiting member 35 includes a transverse limiting portion 351 and a longitudinal limiting portion 352 ; the transverse limiting portion 351 is perpendicular to the moving direction of the walking mechanism 3 , and the longitudinal limiting portion 352 is perpendicular to the transverse limiting portion 351 , and is installed at both ends of the transverse limiting portion 351 .

[0071] The transverse limiting portion 351 and the longitudinal limiting portion 352 fix the slag bucket 4 from different angles, so that the slag bucket 4 and the traveling mechanism 3 are tightly fixed, the shaking of the slag bucket 4 is reduced, and the stability of the slag transport device and the reliability of operation are improved.

[0072] like Figure 6 and Figure 8 As shown, the traveling mechanism 3 also includes a slag removal device 39, which is installed on the left and right sides of the traveling mechanism 3; wherein the slag removal device 39 includes an adjusting bracket 391 installed on the chassis 32 and a scraper 392 installed on the adjusting bracket 391, and the scraper 392 has an opening at the lower part for the guide rail 1 to be embedded.

[0073] By changing the height of the adjustment bracket 391, the position of the scraper 392 can be adjusted so that the scraper 392 fits the guide rail 1. During the movement, the scraper 392 at the lower part of the slag removal device 39 will sweep away the fine slag and particles attached to the surface of the guide rail 1.

[0074] like Fig. 9 As shown, the slag bucket 4 includes a bucket chamber 41 and a plurality of reinforcing ribs 42; the reinforcing ribs 42 are fixed to the outside of the bucket chamber 41 to form a grid-like envelope structure.

[0075] The presence of the reinforcing ribs 42 effectively increases the overall structural strength of the bucket 4 , reduces deformation and vibration, improves the bucket 4 's ability to withstand thermal expansion, and ensures that the bucket 4 maintains a stable shape during operation or loading.

[0076] like Fig. 9 As shown, the bucket 4 further includes a forklift hole 43 ; the forklift hole 43 is located at the bottom of the bucket 4 and penetrates the bucket 4 transversely.

[0077] When installing the slag bucket 4, the worker operates the forklift to place the slag bucket 4 in the area defined by the limit piece 35 through the forklift hole 43 reserved at the bottom of the slag bucket 4, presses it tightly and ensures that there is no obvious gap between the slag bucket 4 and the limit piece 35 and the support platform 33; similarly, when the slag bucket 4 needs to be unloaded, the worker operates the forklift to remove the slag bucket 4 from the walking mechanism 3 and replace it with a new slag bucket 4.

[0078] Example 3

[0079] like Fig.10An automatic slag transport device is shown, which can be used for waste slag transportation in scenes such as metal smelting workshops, metal processing plants and welding workstations, and can be used to transport waste slag between loading stations and unloading stations, especially when there are multiple slag discharge ports in the loading station to discharge slag. At the loading station, the waste slag to be transported is loaded into the slag transport device, and then the slag transport device transports the waste slag to the unloading station for unloading.

[0080] The guide rail 1 , the sensing element 2 , the traveling mechanism 3 , and the slag bucket 4 of the automatic slag transport device in this embodiment are the same as those in the first embodiment.

[0081] Different from the first embodiment, in the present embodiment, there are two slag discharge ports in the loading station where slag needs to be transported. Therefore, two sensing areas are provided in the loading station and along the movement path of the trigger member 31, namely the first sensing area and the second sensing area, wherein the first sensing area is closer to the unloading station. The first sensing area is located at the No. 1 slag discharge port in the loading station, and the second sensing area is located at the No. 2 slag discharge port in the loading station, and the sensing elements 2 are provided in both sensing areas.

[0082] The control unit included in the automatic slag transport device in this embodiment receives a signal from the sensing element 2, which is recorded as an input signal; and sends a signal to control the motion state of the walking mechanism 3, which is recorded as an output signal. The control unit receives a signal from the sensing element 2, which is recorded as an input signal; and sends a signal to control the motion state of the walking mechanism 3, which is recorded as an output signal. The control unit has a preset mapping relationship between the input signal and the output signal, and sends a corresponding output signal to the walking mechanism 3 according to the mapping relationship and the input signal from the sensing element 2, thereby controlling the motion state of the walking mechanism 3.

[0083] When the motor 38 is in forward rotation, that is, rotating clockwise, the traveling mechanism 3 is in the direction of moving from the unloading station to the loading station; when the motor 38 is in reverse rotation, that is, rotating counterclockwise, the traveling mechanism 3 is in the direction of moving from the loading station to the unloading station.

[0084] When the control unit receives the signal from the remote control box: if the walking mechanism 3 is parked at the sensing element 2 in the loading station or the slag unloading station, the control unit can locate the position of the walking mechanism 3, and directly sends a signal to control the movement of the walking mechanism 3; if the walking mechanism 3 is in a moving state, the control unit cannot locate the position of the walking mechanism 3. At this time, the control unit first sends a signal to control the reverse rotation of the motor 38, so that the walking mechanism 3 moves in the opposite direction and returns to the position of the previous level sensing element 2, and then controls the movement of the walking mechanism 3 according to the priority of the task. In particular, when the walking mechanism 3 is powered off and restarted, the control unit first sends a signal to control the motor 38 to rotate in the opposite direction to that before the restart, controls the walking mechanism 3 to return to the previous level sensing element 2, and after the walking mechanism 3 is clearly located, controls the movement of the walking mechanism 3 according to the signal sent by the remote control box. During operation:

[0085] ① When slag discharge port No. 1 needs to discharge slag, the mapping relationship between the input signal and the output signal is preset as follows: when the control unit receives a signal from the sensing element 2 in the first sensing area, the control unit sends a signal to control the walking mechanism 3 to stop moving; when the control unit receives a signal from the sensing element 2 in the second sensing area, the control unit sends a signal to control the walking mechanism 3 to stop moving; when the control unit receives a signal from the sensing element 2 in the unloading station, the control unit sends a signal to control the walking mechanism 3 to stop moving.

[0086] 1) The traveling mechanism 3 stops at the unloading station or the loading station, and the control unit receives the signal from the remote control box to move the slag transport device to the No. 1 slag discharge port, and controls the motor 38 to rotate forward or reverse, so that the traveling mechanism 3 moves to the No. 1 slag discharge port in the loading station. When the traveling mechanism 3 moves to the No. 1 slag discharge port, the trigger member 31 touches the sensing element 2 at the No. 1 slag discharge port. The sensing element 2 rotates under the squeezing action of the trigger member 31, and at this time the sensing element 2 feeds back to the control unit a signal that the traveling mechanism 3 has reached the No. 1 slag discharge port. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the traveling mechanism 3 stops at the No. 1 slag discharge port in the loading station.

[0087] 2) When the walking mechanism 3 is moving and the motor 38 is rotating forward, the control unit receives a signal from the remote control box to move the slag transport device to the No. 1 slag discharge port, controls the motor 38 to reverse, and the walking mechanism 3 moves in the opposite direction. When the walking mechanism 3 touches the upper-level sensing element 2, the walking mechanism 3 is triggered to stop. If the walking mechanism 3 is located at the unloading station when the walking mechanism 3 stops moving, the control unit sends a signal to move the walking mechanism 3 to the No. 1 slag discharge port, controls the motor 38 to rotate forward, and the walking mechanism 3 moves to the No. 1 slag discharge port until it stops at the No. 1 slag discharge port.

When the walking mechanism 3 touches the upper-level sensing element 2, the walking mechanism 3 is triggered to stop. If the walking mechanism 3 is located at the No. 2 slag discharge port when the walking mechanism 3 stops moving, the control unit sends a signal to move the walking mechanism 3 to the No. 1 slag discharge port, controls the motor 38 to rotate in reverse, and the walking mechanism 3 moves to the No. 1 slag discharge port until it stops at the No. 1 slag discharge port.

[0089] ② When slag discharge is required at the No. 2 slag discharge port, the mapping relationship between the input signal and the output signal is preset as follows: when the control unit receives a signal from the sensing element 2 in the first sensing area, the control unit sends a signal to control the walking mechanism 3 to continue moving; when the control unit receives a signal from the sensing element 2 in the second sensing area, the control unit sends a signal to control the walking mechanism 3 to stop moving; when the control unit receives a signal from the sensing element 2 in the unloading station, the control unit sends a signal to control the walking mechanism 3 to stop moving.

When the travel mechanism 3 moves to the No. 1 slag discharge port, the trigger 31 touches the sensing element 2 at the No. 1 slag discharge port. The sensing element 2 rotates under the extrusion of the trigger 31, and the sensing element 2 feedbacks to the control unit that the travel mechanism 3 has reached the No. 1 slag discharge port but has not reached the No. 2 slag discharge port. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to continue to rotate forward, and the travel mechanism 3 continues to move to the No. 2 slag discharge port. When the travel mechanism 3 moves to the No. 2 slag discharge port, the trigger 31 touches the sensing element 2 at the No. 2 slag discharge port. The sensing element 2 rotates under the extrusion of the trigger 31, and the sensing element 2 feedbacks to the control unit that the travel mechanism 3 has reached the No. 2 slag discharge port. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the traveling mechanism 3 stops at the No. 2 slag discharge port in the loading station.

When the walking mechanism 3 moves to the No. 2 slag discharge port, the trigger member 31 touches the sensing element 2 at the No. 2 slag discharge port. The sensing element 2 rotates under the squeezing action of the trigger member 31, and at this time the sensing element 2 feeds back to the control unit a signal that the walking mechanism 3 has reached the No. 2 slag discharge port. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the walking mechanism 3 stops at the No. 2 slag discharge port in the loading station.

When the walking mechanism 3 touches the upper-level sensing element 2, the walking mechanism 3 is triggered to stop. If the walking mechanism 3 is located at the unloading station when the walking mechanism 3 stops moving, the control unit sends a signal to move the walking mechanism 3 to the No. 2 slag discharge port, controls the motor 38 to rotate forward, and the walking mechanism 3 moves to the No. 2 slag discharge port until it stops at the No. 2 slag discharge port.

[0093] 4) When the walking mechanism 3 is moving and the motor 38 is rotating in reverse, the control unit receives a signal from the remote control box to move the slag transport device to the No. 2 slag discharge port, controls the motor 38 to rotate forward, and the walking mechanism 3 moves in the reverse direction. When the walking mechanism 3 touches the upper-level sensing element 2, the walking mechanism 3 is triggered to stop. If the walking mechanism 3 is located at the No. 1 slag discharge port when the walking mechanism 3 stops moving, the control unit sends a signal to move the walking mechanism 3 to the No. 2 slag discharge port, controls the motor 38 to rotate forward, and the walking mechanism 3 moves to the No. 2 slag discharge port until it stops at the No. 2 slag discharge port.

[0094] ③ When slag unloading is required, the mapping relationship between the input signal and the output signal is preset as follows: when the control unit receives a signal from the sensing element 2 in the first sensing area, the control unit sends a signal to control the walking mechanism 3 to continue moving; when the control unit receives a signal from the sensing element 2 in the second sensing area, the control unit sends a signal to control the walking mechanism 3 to stop moving; when the control unit receives a signal from the sensing element 2 in the unloading station, the control unit sends a signal to control the walking mechanism 3 to stop moving.

[0095] 1) The walking mechanism 3 stops at the No. 1 slag discharge port. The control unit receives the signal from the remote control box to move the slag transport device to the unloading station, and controls the motor 38 to reverse, so that the walking mechanism 3 moves to the unloading station. When the walking mechanism 3 moves to the unloading station, the trigger 31 touches the sensing element 2 at the unloading station. The sensing element 2 rotates under the squeezing action of the trigger 31, and at this time the sensing element 2 feeds back to the control unit a signal that the walking mechanism 3 has reached the unloading station. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the walking mechanism 3 stops at the unloading station.

When the traveling mechanism 3 moves to the No. 1 slag discharge port, the trigger 31 touches the sensing element 2 at the No. 1 slag discharge port. The sensing element 2 rotates under the extrusion of the trigger 31, and the sensing element 2 feedbacks to the control unit that the traveling mechanism 3 has reached the No. 1 slag discharge port but has not yet reached the unloading station. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to continue to reverse, so that the traveling mechanism 3 continues to move to the unloading station. When the traveling mechanism 3 moves to the unloading station, the trigger 31 touches the sensing element 2 at the unloading station. The sensing element 2 rotates under the extrusion of the trigger 31, and the sensing element 2 feedbacks to the control unit that the traveling mechanism 3 has reached the unloading station. Based on the feedback signal of the sensing element 2, the control unit controls the motor 38 to stop and brake, so that the traveling mechanism 3 stops at the unloading station.
