Description

Technical Field

[0001] The present application relates to the technical field of metallurgical transportation equipment, and in particular to a slag ladle trunnion locking device and a slag ladle trunnion locking method. Background Art

[0002] Tank carriers are special equipment that integrates the functions of self-loading and unloading slag bags and tipping slag, and are widely used in metallurgical slag treatment processes. Tank carriers support and fix the trunnions of the slag bags through the fork shoe seat and lock plate on the working mechanism and perform a certain degree of restraint to achieve the operation of various functional requirements. During the process of tanking, transportation and tipping slag bags, the safety and reliability of the fork shoe seat and lock plate become the key to the long-term and stable operation of the tank carrier.

[0003] Traditional tank-carrying vehicles only monitor the opening and closing status of the lock plate, but cannot correctly judge whether the tank-carrying vehicle has fully forked the tank (fully forked the tank means that the ear shaft of the slag bag is fully embedded in the fork bearing shaft, and the ear shaft is against the lowest point of the U-shaped opening of the fork bearing shaft). When there are blind spots, environmental smoke and haze, and unclear vision, the driver is prone to misjudgment that the tank has been fully forked, which greatly increases the danger and safety risk of forked tank operations. Therefore, the existing device has the problem of not being able to judge whether the tank is fully forked. Summary of the invention

The first fork bearing shaft 101 is arranged on the work frame 100, and the first fork bearing shaft 101 includes a first receiving opening 1010, and the first receiving opening 1010 is used to accommodate the left trunnion 20. The first in-position sensing device 102 is arranged on the work frame 100, and the first in-position sensing device 102 is used to detect whether the left trunnion 20 abuts against the lowest point of the first receiving opening 1010. The second fork bearing shaft 103 is arranged on the work frame 100, and the second fork bearing shaft 103 includes a second receiving opening 1030, and the second receiving opening 1030 is used to accommodate the right trunnion 21. The second in-position sensing device 104 is arranged on the work frame 100, and the second in-position sensing device 104 is used to detect whether the right trunnion 21 abuts against the lowest point of the second receiving opening 1030.

[0091] Please also refer to Figure 1 and Figure 2 By setting the first in-position sensing device 102 and the second in-position sensing device 104, it is possible to respectively detect whether the left ear shaft 20 is against the lowest point of the first accommodating opening 1010 and whether the right ear shaft 21 is against the lowest point of the second accommodating opening 103, thereby realizing the judgment of whether the first fork bearing shaft 101 and the second fork bearing shaft 103 are completely forked, thereby reducing the danger of fork bearing operation and the risk of safety hazards.

[0092] Please also refer to Figure 1 and Figure 2 , the workbench 100 can be U-shaped, and the workbench 100, the first fork bearing shaft 101 and the second fork bearing shaft 103 can be made of steel. The shape of the first accommodating opening 1010 and the shape of the second accommodating opening 1030 can be U-shaped. The opening of the first accommodating opening 1010 and the opening of the second accommodating opening 1030 can face a direction parallel to the positive direction of the X-axis. The first fork bearing shaft 101 and the second fork bearing shaft 103 can be fixed to the top surface of the workbench 100 by welding or riveting. The first fork bearing shaft 101 and the second fork bearing shaft 103 can be located on the left and right sides of the workbench 100, respectively.

[0093] Please also refer to Figure 1 and Figure 2 , the first fork bearing shaft 101 includes a semi-cylindrical surface in the direction away from the opening. The diameter of the semi-cylindrical surface of the first fork bearing shaft 101 and the diameter of the left ear shaft 20 can be the same. The second fork bearing shaft 103 includes a semi-cylindrical surface in the direction away from the opening. The diameter of the semi-cylindrical surface of the second fork bearing shaft 103 and the right angle of the right ear shaft 21 can be the same. The first in-position sensing device 102 can be a strain gauge, or it can be composed of a first linear displacement sensor 1020 and a first limit frame 1021 as described in the subsequent contents of the embodiment (please refer to the first linear displacement sensor 1020 and the first limit frame 1021 for details). Figure 4 ).

[0094] Please also refer to Figure 1 and Figure 2 When the first in-position sensing device 102 is a strain gauge, it can be attached to the lowest point of the first receiving opening 1010. When the first in-position sensing device 102 is a strain gauge, when the left ear shaft 20 contacts the first in-position sensing device 102, the first in-position sensing device 102 generates a signal that the left ear shaft 20 has abutted against the lowest point of the first receiving opening 1010, and at this time, the first fork bearing shaft 101 has achieved full fork canning.

[0095] Please also refer to Figure 1 and Figure 2 The second in-position sensing device 104 may be a strain gauge, or may be composed of a second linear displacement sensor 1040 and a second limit frame 1041 as described in the subsequent embodiments (the second linear displacement sensor 1040 and the second limit frame 1041 are described in detail in the following embodiments). Figure 6 ). When the second in-position sensing device 104 is a strain gauge, it can be pasted to the lowest point of the second receiving opening 1030. When the second in-position sensing device 104 is a strain gauge, when the right ear shaft 21 contacts the second in-position sensing device 104, the second in-position sensing device 104 generates a signal that the right ear shaft 21 has abutted against the lowest point of the second receiving opening 1030, and at this time, the second fork bearing shaft 103 has achieved a complete fork tank.

[0096] Please also refer to Figure 3 and Figure 4 Optionally, the first in-position sensing device 102 includes a first linear displacement sensor 1020 and a first limit frame 1021, the first linear displacement sensor 1020 and the working frame 100 are movably connected, the first linear displacement sensor 1020 and the first limit frame 1021 are movably connected, the first limit frame 1021 and the working frame 100 are movably connected, the first limit frame 1021 is used to maintain contact with the left ear shaft 20, and the first linear displacement sensor 1020 is used to detect whether the left ear shaft 20 is against the lowest point of the first accommodating opening 1010.

[0097] like Figure 4 As shown, with such an arrangement, during the process of the lowest point of the first accommodating opening 1010 moving to contact with the left ear shaft 20, the first linear displacement sensor 1020 can maintain real-time monitoring of the position of the left ear shaft 20, thereby avoiding the disconnection of the signal of the first linear displacement sensor 1020 and affecting the fork tank process monitoring (because the first limit frame 1021 maintains contact with the left ear shaft 20 when rotating, so that the first linear displacement sensor 1020 always has a signal), which can not only improve the accuracy of the fork tank, but also improve the safety of the fork tank operation.

[0098] like Figure 4As shown, the bottom end of the first linear displacement sensor 1020 can be pivotally connected to the work frame 100, and the top end of the first linear displacement sensor 1020 can be pivotally connected to the upper left end of the first limiting frame 1021. The lower left end of the first limiting frame 1021 can be pivotally connected to the work frame 100.

[0099] Please also refer to Figure 3 and Figure 4 , in tanker 1 (tanker 1, please refer to Figure 8 ) and the first leg oil cylinder 110, when the left ear shaft 20 enters the first receiving opening 1010 and abuts against the first limiting frame 1021, the first limiting frame 1021 can be pushed to rotate (the rotation direction of the first limiting frame 1021 can refer to Figure 4 When the first limit frame 1021 rotates, it can push the first linear displacement sensor 1020 to shorten. When the left ear shaft 20 abuts against the lowest point of the first accommodating opening 1010, the first linear displacement sensor 1020 no longer shortens, thereby realizing the detection of the left ear shaft 20 abutting against the lowest point of the first accommodating opening 1010 by the first linear displacement sensor 1020.

[0100] Please also refer to Figure 5 and Figure 6 Optionally, the second in-position sensing device 104 includes a second linear displacement sensor 1040 and a second limit frame 1041, the second linear displacement sensor 1040 and the working frame 100 are movably connected, the second linear displacement sensor 1040 and the second limit frame 1041 are movably connected, the second limit frame 1041 and the working frame 100 are movably connected, the second limit frame 1041 is used to maintain contact with the right ear shaft 21, and the second linear displacement sensor 1040 is used to detect whether the right ear shaft 21 is against the lowest point of the second accommodating opening 1030.

[0101] like Figure 6 As shown, with such arrangement, during the process when the lowest point of the second accommodating opening 1030 moves to contact with the right ear shaft 21, the second linear displacement sensor 1040 can maintain real-time monitoring of the position of the right ear shaft 21, thereby avoiding the disconnection of the signal of the second linear displacement sensor 1040 and affecting the fork tank process monitoring (because the second limit frame 1041 maintains contact with the right ear shaft 21 when rotating, so that the second linear displacement sensor 1040 always has a signal), which can improve the accuracy of the fork tank and improve the safety of the fork tank operation.

[0102] like Figure 6As shown, the bottom end of the second linear displacement sensor 1040 can be pivotally connected to the work frame 100, and the top end of the second linear displacement sensor 1040 can be pivotally connected to the upper right end of the second limiting frame 1041. The lower right end of the second limiting frame 1041 can be pivotally connected to the work frame 100. The second limiting frame 1041 can include an arc segment with the same diameter as the diameter of the right ear shaft 21.

[0103] Please also refer to Figure 5 and Figure 6 , in tanker 1 (tanker 1, please refer to Figure 8 ) and the second leg oil cylinder 118, when the right ear shaft 21 enters the second receiving opening 1030 and abuts against the second limiting frame 1041, the second limiting frame 1041 can be pushed to rotate (the rotation direction of the second limiting frame 1041 can refer to Figure 6 When the second limit frame 1041 rotates, it can push the second linear displacement sensor 1040 to shorten. When the right ear shaft 21 abuts against the lowest point of the second accommodating opening 1030, the second linear displacement sensor 1040 no longer shortens, thereby realizing the detection of the right ear shaft 21 abutting against the lowest point of the second accommodating opening 1030 by the second linear displacement sensor 1040.

[0104] Please also refer to Figure 4 and Figure 6 The first linear displacement sensor 1020 and the second linear displacement sensor 1040 may be resistive displacement sensors. The material of the first limit frame 1021 and the material of the second limit frame 1041 may be steel. The shape of the first limit frame 1021 may be an arc (e.g., a sickle shape) to keep in contact with the left ear shaft 20 during rotation. The shape of the second limit frame 1041 may be an arc (e.g., a sickle shape) to keep in contact with the right ear shaft 21 during rotation.

[0105] Please also refer to Figure 4 and Figure 6 Optionally, the first limiting frame 1021 includes a first inner edge opening 10210 having the same diameter as the left ear shaft 20, and the second limiting frame 1041 includes a second inner edge opening 10410 having the same diameter as the right ear shaft 21. Providing the first inner edge opening 10210 having the same diameter as the left ear shaft 20 can prevent the first limiting frame 1021 from preventing the first receiving opening 1010 from contacting the left ear shaft 20 due to a too small diameter, and prevent the first limiting frame 1021 from being unable to maintain contact with the left ear shaft 20 due to an overly large diameter.

[0106] Please also refer to Figure 4 and Figure 6The second inner edge 10410 having the same diameter as the right ear shaft 21 can prevent the second stop frame 1041 from preventing the second receiving opening 1030 from contacting the right ear shaft 21 due to a too small diameter, and prevent the second stop frame 1041 from failing to maintain contact with the right ear shaft 21 due to a too large diameter. The first inner edge 10210 and the second inner edge 10410 can be cylindrical surfaces.

[0107] like Figure 4 As shown, optionally, the slag ladle trunnion locking device further includes a first travel switch 105, a first swing arm 106, a first connecting rod 107 and a first locking plate 108. The first travel switch 105 is disposed on the work frame 100. The first swing arm 106 is movably connected to the first travel switch 105. The first connecting rod 107 is movably connected to the first swing arm 106. The first locking plate 108 is movably connected to the first connecting rod 107, wherein when the first locking plate 108 rotates, the first swing arm 106 triggers the first travel switch 105 to turn on the first travel switch 105, and the first locking plate 108 is used to lock the left trunnion 20.

[0108] like Figure 4 As shown, such an arrangement can maintain the monitoring of the opening of the first lock plate 108 by the first travel switch 105, and prevent the signal of the first travel switch 105 from being disconnected and releasing or loosening the lock on the left ear shaft 20.

[0109] like Figure 4 As shown, the first travel switch 105 can be a direct-acting travel switch, which includes a first contact. When the first swing arm 106 contacts the first contact, the first travel switch 105 generates a disconnect signal. When the first swing arm 106 and the first contact are out of contact, the first travel switch 105 generates a connect signal.

[0127] Control the first fork shoe shaft 101 to approach the left ear shaft 20; and

[0128] When the first in-position sensing device 102 detects that the left ear shaft 20 abuts against the lowest point of the first receiving opening 1010, the first displacement sensor 111 detects that the extension of the first leg oil cylinder 110 is less than or equal to the first displacement preset value, and the first pressure sensor 123 detects that the pressure is greater than or equal to the first pressure preset value, the first locking plate oil cylinder 109 is controlled to push the first locking plate 108 to rotate and close. In this way, the first locking plate 108 can be closed when the first fork bearing shaft 101 is completely forked, so as to prevent the first locking plate 108 from being misoperated and improve the accuracy of locking the package.

[0129] like Figure 4 As shown, controlling the first fork bearing shaft 101 to approach the left ear shaft 20 includes: controlling the first fork bearing shaft 101 to move along the positive direction parallel to the X-axis until the displacement change of the first linear displacement sensor 1020 is greater than or equal to 1mm and less than or equal to 10mm and stops, and then controlling the first leg cylinder 109 to move along the positive direction parallel to the Y-axis until the displacement change range of the first linear displacement sensor 1020 is greater than 10mm and less than or equal to 20mm and stops.

[0130] Optionally, the slag ladle trunnion locking method also includes:

[0131] Control the second fork shoe shaft 103 to approach the right ear shaft 21; and

[0132] When the second in-position sensing device 104 detects that the right ear shaft 21 abuts against the lowest point of the second receiving opening 1030, the second displacement sensor 119 detects that the extension of the second leg oil cylinder 118 is less than or equal to the second displacement preset value, and the second pressure sensor 120 detects that the pressure is greater than or equal to the second pressure preset value, the second locking plate oil cylinder 117 is controlled to push the second locking plate 116 to rotate and close. In this way, the second locking plate 116 can be closed when the second fork bearing shaft 103 is completely forked, preventing the second locking plate 116 from being misoperated and improving the accuracy of locking the package.

[0133] like Figure 6 As shown, controlling the second fork bearing shaft 103 to approach the right ear shaft 21 includes: controlling the second fork bearing shaft 103 to move along the positive direction parallel to the X-axis until the displacement change of the second linear displacement sensor 1040 is greater than or equal to 1mm and less than or equal to 10mm and stops, and then controlling the second support leg cylinder 118 to move along the positive direction parallel to the Y-axis until the displacement change range of the second linear displacement sensor 1040 is greater than 10mm and less than or equal to 20mm and stops.

[0134] Please also refer to Figure 4 , Figure 6 and Figure 8 When loading the slag bag 2, the tank holding vehicle 1 can move slowly along the positive direction parallel to the X-axis with the work frame 100. When the left ear shaft 20 on the slag bag 2 contacts the first limit frame 1021, and the right ear shaft 21 on the slag bag 2 contacts the second limit frame 1041, the first linear displacement sensor 1020 and the second linear displacement sensor 1040 will feedback the canning signal. When the displacement variation range of the first linear displacement sensor 1020 and the second linear displacement sensor 1040 is greater than or equal to 1mm (millimeter, mm in other positions has the same meaning) and less than or equal to 10mm, it indicates that the left ear shaft 20 has abutted against the top of the first receiving opening 1010 in the X-axis direction and the right ear shaft 21 has abutted against the top of the second receiving opening 1030 in the X-axis direction.

[0135] During the entire process of loading the slag bag 2, the signal sizes generated by the first linear displacement sensor 1020 and the second linear displacement sensor 1040 must be the same, indicating that the slag bag 2 fork tank is in place, and the operation can continue. Otherwise, the operation cannot continue.

[0136] Please also refer to Figures 3 to 6 At this time, the first leg oil cylinder 110 and the second leg oil cylinder 118 can be controlled to move upward in a direction parallel to the Y axis, pushing the work frame 100 (the first fork bearing shaft 101 and the second fork bearing shaft 103 move with the work frame 100) to move upward. When the displacement variation range of the first linear displacement sensor 1020 and the second linear displacement sensor 1040 is greater than 10 mm and less than or equal to 20 mm, it indicates that the left ear shaft 20 has abutted against the lowest point of the first receiving opening 1010 and the right ear shaft 21 has abutted against the lowest point of the second receiving opening 1030.

[0137] Please also refer to Figures 3 to 7When it is detected that the extension amount of the first leg cylinder 110 is less than or equal to 30 mm and the first pressure sensor 123 detects a pressure greater than or equal to 8 MPa, and when it is detected that the extension amount of the second leg cylinder 118 is less than or equal to 30 mm and the second pressure sensor 120 detects a pressure greater than or equal to 8 MPa, the first lock plate cylinder 109 is controlled to close the first lock plate 108 and the second lock plate 116 is controlled to close the second lock plate 116.
