The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] In the related technology, drill rods are commonly used consumables in the ferroalloy ore furnace operation. They need to be replaced in time after one is used up. Traditionally, drill rods are replaced manually, but since drill rods are heavy and have a heavy gravity, multiple people are required to work together. Therefore, manual replacement of drill rods is difficult to ensure the continuity of the drill rod replacement action and the consistency of the rhythm. The replacement efficiency is low and the labor intensity is high. In addition, the on-site environment is harsh and the working temperature is high, so workers are at risk of burns and scalds.

[0033] Reference below Figure 1-Figure 4 The drill rod transmission device of the submerged arc furnace unloading robot according to the embodiment of the present invention is described.

[0034] The drill rod transmission device 100 according to the present invention comprises: a lifting bracket and a transmission bracket, the lifting bracket is movably provided with a first movable component 122, the first movable component 122 is used to support the drill rod 11 and drive the drill rod 11 to move from the bottom of the lifting bracket to the top of the lifting bracket; the transmission bracket is movably provided at the top of the lifting bracket, the transmission bracket is provided with a second movable component 23 that moves toward the end of the transmission bracket, the second movable component 23 is used to drive the drill rod 11 to move on the transmission bracket; wherein the transmission bracket can selectively move relative to the lifting bracket to adjust the position of the end of the transmission bracket.

[0035] In some specific embodiments, the drill rod transmission device 100 is composed of a lifting bracket and a transmission bracket. The lifting bracket is fixed on the ground. A movable first movable component 122 is provided on the lifting bracket. The first movable component 122 can drive the drill rod 11 to be transmitted from the bottom of the lifting bracket to the top of the lifting bracket, that is, the first movable component 122 can transport the drill rod 11 from the ground to a specified height. The starting end of the transmission bracket is movably arranged at the top of the lifting bracket, and the end of the transmission bracket extends toward the specified working position. A movable second movable component 23 is provided on the transmission bracket. When the first movable component 122 drives the drill rod 11 to move to the highest point on the top of the lifting bracket, the drill rod 11 slides from the first movable component 122 to the second movable component 23, and the second movable component 23 drives the drill rod 11 to be transported toward the end of the transmission bracket, that is, the specified working position, thereby improving the automation and timeliness of the transportation and replacement of the drill rod 11, and improving the working efficiency. At the same time, the drill rod transmission device 100 is used to realize automatic drilling instead of manual operation, reduce the intensity of manual labor, and improve the safety of the workers during the transmission of the drill rod 11.

[0036] The transmission bracket can be selectively moved relative to the lifting bracket to adjust the position of the end of the transmission bracket to ensure that the drill rod 11 is quickly and accurately delivered to the specific position of the furnace discharge equipment, reducing the waiting time and the need for secondary adjustment, and improving the overall operating efficiency. At the same time, when the drill rod transmission device 100 is not in working state, the transmission bracket moves relative to the lifting bracket, thereby reducing the lateral occupied volume of the drill rod transmission device 100, reducing the occupied space, and facilitating workers to carry out cleaning and other maintenance work.

[0037] According to the drill rod transmission device 100 of the present invention, a movable first movable component 122 is set on the lifting bracket, and a movable second movable component 23 is set on the transmission bracket. The first movable component 122 transmits the drill rod 11 from the ground to a specified height. When the drill rod 11 is lifted and transmitted to the specified height, the second movable component 23 transfers the drill rod 11 to a specified working position, thereby reducing manual labor intensity, improving the automation and timeliness of the transportation and replacement of the drill rod 11, and improving working efficiency.

[0038] According to some embodiments of the present invention, the transmission bracket is rotatably disposed on the lifting bracket, and the transmission bracket is rotatably connected to the top of the lifting bracket to flexibly adjust the angle of the transmission bracket to adapt to the working requirements of different heights or positions, and when the drill rod transmission device 100 is in a non-working state, the transmission bracket can be flipped upward to reduce the occupied space, which is convenient for on-site cleaning and other maintenance activities. At the same time, after flipping the transmission bracket to a safe position, it can effectively avoid accidental collisions of workers, thereby improving the safety of workers at work.

[0039] In other specific embodiments, the transmission bracket translates relative to the lifting bracket, and the transmission bracket can move relative to the lifting bracket in a straight line direction, so that the drill rod transmission device 100 can extend or shorten the transmission distance of the transmission bracket according to actual needs, thereby increasing the flexibility and adaptability of transporting the drill rod 11.

[0040] According to some embodiments of the present invention, the drill rod transmission device also includes: a hinge portion and a guide component, the hinge portion is arranged on the transmission bracket and is rotatably connected to the lifting bracket; the guide component is arranged on the lifting bracket and is arranged close to the transmission bracket, the guide component is formed with a guide slope 221, and the guide slope 221 is close to the transmission bracket in the direction close to the starting end of the transmission bracket.

[0041] In some specific embodiments, a hinge portion and a guide component are further provided in the drill rod transmission device. A hinge portion rotatably connected to the lifting bracket is formed on the transmission bracket. The existence of the hinge portion enables the transmission bracket to adjust the angle according to actual needs to adapt to different working heights and position requirements, thereby improving the flexibility of the transmission device 100. A guide component 22 extending toward the top of the lifting bracket is provided on the starting end of the transmission bracket. When the drill rod 11 on the first movable component 122 moves to the highest point on the top, it slides into the guide component 22, and the drill rod 11 then slides toward the second movable component 23 through the guide component 22. The existence of the guide component 22 ensures that the drill rod 11 can smoothly transition from the first movable component 122 to the second movable component 23, thereby avoiding the risk of jamming or deviation, and also preventing the drill rod 11 from sliding from the first movable component 122 to the second movable component 23. The sudden contact between the rod 11 and the second movable part 23 produces a large impact, which effectively prevents the drill rod 11 and the second movable part 23 from being damaged. A guide bevel 221 is formed on the guide part 22. When the drill rod 11 moves from the first movable part 122 to the highest point at the top and slides into the guide part 22, the guide bevel 221 can guide the drill rod 11 to slide or roll smoothly along a predetermined path toward the second movable part 23. As the drill rod 11 moves along the guide bevel 221, the guide bevel 221 gradually approaches the transmission bracket in the direction from the starting end to the end of the transmission bracket, gradually reducing the distance between the guide bevel 221 and the second movable part 23, so that the drill rod 11 slides along the path guided by the guide bevel 221, ensuring that the drill rod 11 remains stable during the entire transfer process without shaking or deflection, thereby improving the stability and reliability of the transportation of the drill rod 11.

[0042] In addition, the drill rod 11 rolls along the guide slope 221 toward the second movable component 23. When the drill rod 11 rolls to its preset position, the second movable component 23 can play a certain stopping role on the drill rod 11 to limit the continued rolling of the drill rod 11, effectively preventing the drill rod 11 from rolling directly off the transmission bracket, and at the same time preventing multiple drill rods 11 from colliding with each other, thereby improving the stability of the transportation of the drill rod 11.

[0043] According to some embodiments of the present invention, the hinge portion is disposed at the starting end of the transmission bracket, and the guide slope 221 is configured to be arc-shaped and recessed toward the hinge portion.

[0044] In some specific embodiments, a hinge portion for hinge connection with the lifting bracket is formed at the starting end of the transmission bracket, and the hinge portion is arranged at the starting end of the lifting bracket, so that the installation and disassembly process of the lifting bracket and the transmission bracket is more direct and faster, reducing the operation time and difficulty, and also reducing the risk of incorrect installation. The design of the arc-shaped guide slope 221 makes the contact point between the guide component 22 and the drill rod 11 not a single sharp edge, but an area that gradually changes along the curved surface, which means that when the drill rod 11 contacts the guide slope 221, the impact force will not be concentrated on one point, but will be effectively dispersed to a larger contact area, thereby reducing local stress concentration and reducing damage to the drill rod 11; The inclined surface 221 is recessed toward the hinge portion of the transmission bracket to play a buffering role in the process of transferring the drill rod 11 from the lifting bracket to the transmission bracket. The arc-shaped and recessed characteristics of the guiding inclined surface 221 help to disperse and absorb the impact energy generated when the drill rod 11 falls, preventing the drill rod 11 from suddenly colliding with the transmission bracket and causing damage to the transmission bracket, thereby improving the reliability of the transmission device 100. When the drill rod 11 falls and encounters a large impact, the curved guiding inclined surface 221 recessed toward the hinge portion can better control the movement direction of the drill rod 11, so that it moves along the expected trajectory, effectively preventing the drill rod 11 from deviating during the sliding process, avoiding accidents, and improving the safety of the drill rod 11 during transportation.

[0045] According to some embodiments of the present invention, the transmission device 100 also includes: a first driving member 31, which is arranged on the lifting bracket and is used to drive the transmission bracket to rotate relative to the lifting bracket, so that the transmission bracket rotates relative to the lifting bracket to switch between the standby state and the drill state.

[0046] In some specific embodiments, the transmission device 100 is further provided with a first driving member 31, one end of the first driving member 31 is provided on the lifting bracket, and the other end of the first driving member 31 is provided on the transmission bracket. A retractable driving end is formed on the first driving member 31, and the driving end is connected to the transmission bracket. The driving end can drive the transmission bracket to rotate relative to the lifting bracket to switch between the standby state (non-working state) and the drilling state (working state). When the drill rod transmission device 100 is in the drilling state (working state), the first driving member 31 can provide support force for the transmission bracket. , so that the transmission bracket is in a horizontal position to ensure the stability, continuity and reliability of the transmission of the drill rod 11; when the drill rod transmission device 100 stops working and is in a standby state (non-working state), the driving end of the first driving member 31 extends and gives an upward thrust to the transmission bracket, so that the transmission bracket flips upward around the hinge. When the transmission bracket flips to the specified position, the first driving member 31 stops running and locks, so that the transmission bracket is fixed in the specified position without sagging, reducing the space occupied by the drill rod transmission device 100 and facilitating the staff to clean and maintain the drill rod transmission device 100.

[0047] In addition, the first driving member 31 can be constructed as an oil cylinder, an air cylinder or an electric push rod, etc., but is not limited to these three.

[0048] According to some embodiments of the present invention, a first locking portion is provided on the lifting bracket, and a second locking portion is provided on the transmission bracket. The first locking portion and the second locking portion can be selectively locked to limit the rotation of the transmission bracket relative to the lifting bracket, thereby ensuring that in the standby state, the lifting bracket and the transmission bracket will not accidentally move relative to each other, thereby improving the safety and reliability of the operation of the drill rod transmission device 100. The staff can choose whether to lock according to actual needs, and flexibly adapt to different work scenarios and task requirements.

[0049] According to some embodiments of the present invention, the first locking portion is configured as a locking hole 101, and the second locking portion is configured as a locking pin 25, which is telescopically arranged on the transmission bracket and is suitable for extending in a standby state and cooperating with the locking hole 101.

[0050] In some specific embodiments, the first locking portion is arranged on the surface of the lifting bracket, the first locking portion can be constructed as a locking hole 101, and the second locking portion can be constructed as a locking pin 25. One end of the locking pin 25 is connected to the reciprocating member 26. The locking pin 25 and the reciprocating member 26 are both arranged on the transmission bracket. When the drill rod transmission device 100 is in a standby state, that is, a non-working state, the first driving member 31 pushes the transmission bracket to rotate to the extreme position, and the reciprocating member 26 pushes the locking pin 25 to move toward the locking hole 101. As the reciprocating member 26 is pushed forward, the locking pin 25 gradually approaches and finally inserts into the locking hole 101. In the hole 101, the locking pin 25 is tightly matched with the locking hole 101 to limit the movement of the transmission bracket relative to the lifting bracket in the standby state (non-working state), which can effectively prevent the transmission bracket from falling when the first driving member 31 fails, thereby improving the safety and reliability of the drill rod transmission device 100; when the drill rod transmission device 100 is to be transformed from the standby state (non-working state) to the drill state (working state), the reciprocating member 26 pulls the locking pin 25 to gradually leave the locking hole 101 to release the lock between the transmission bracket and the lifting bracket to ensure the stability of the subsequent transmission of the drill rod 11.

[0051] According to some embodiments of the present invention, a support component 123 is provided on the lifting bracket. The support component 123 is suitable for cooperating with the transmission bracket in the upper drill state to limit the rotation of the transmission bracket. The support component 123 can selectively move in the height direction relative to the lifting bracket.

[0052] In some specific embodiments, a support component 123 is provided on one end of the lifting bracket close to the starting end of the transmission bracket. When the transmission bracket is in the drilling state, the support component 123 will be activated and adjusted to an appropriate height so that it is in close contact with the transmission bracket, thereby limiting the rotation of the transmission bracket and preventing the transmission bracket from rotating during the drilling process, reducing the risk of accidents and improving the safety of the drill rod transmission device. In the standby state or when the angle of the transmission bracket needs to be adjusted, the support component 123 can be loosened to give the transmission bracket sufficient room for movement and operational flexibility.

[0053] According to some embodiments of the present invention, the drill rod transmission device 100 also includes: a first sensor 33, a second sensor 34 and a controller, the first sensor 33 is arranged at the starting end of the transmission bracket and is used to detect that the drill rod 11 enters the transmission bracket, and the second sensor 34 is arranged at the end of the transmission bracket and is used to detect that the drill rod 11 leaves the transmission bracket; the controller is electrically connected to the first sensor 33, the second sensor 34 and the transmission bracket, respectively, and the controller controls the second moving component 23 of the transmission bracket to start after the first sensor 33 detects that the drill rod enters, and controls the second moving component 23 of the transmission bracket to stop after the second sensor 34 detects that the drill rod leaves.

[0054] In some specific embodiments, a first sensor 33, a second sensor 34 and a second driving member 32 are further provided in the drill rod transmission device 100. The first sensor 33 is located at the starting end of the transmission bracket, and the second sensor 34 is located at the end of the transmission bracket. The first sensor 33, the second sensor 34 and the transmission bracket are electrically connected to the controller respectively. During operation, the drill rod 11 is transmitted to a specified height by the lifting bracket and passes the highest point of the lifting bracket, and then slides onto the transmission bracket along the guide component 22. When the drill rod 11 passes the highest point of the lifting bracket, it can be detected by the first sensor 33. The first sensor 33 transmits a signal to the controller, and the controller then sends The controller 100 outputs a command to stop the first movable component 122 provided on the lifting bracket and controls the second movable component 23 provided on the transmission bracket to start moving. The second movable component 23 drives the drill rod 11 to move toward the end of the transmission bracket. When the drill rod 11 moves to the end of the transmission bracket, the drill rod 11 slides to the specified operation position. Since a second sensor 34 is installed at the end of the transmission bracket, the drill rod 11 will be detected by the second sensor 34 during the process of sliding to the specified position. The second sensor 34 transmits a signal to the controller, and the controller immediately issues a command to stop the second movable component 23, thereby realizing the intelligent automatic control of the drill rod transmission device 100.

The first sensor is installed on the guide component and is located at the smooth area 222. When the drill rod 11 passes the highest point of the lifting bracket and contacts the smooth area 222 of the guide component, it can be detected by the first sensor 33. The first sensor 33 transmits a signal to the control system, and the control system issues an instruction to stop the first movable component 122 set on the lifting bracket and control the second driving member 32 to start driving the second movable component 23 set on the transmission bracket to move. The second movable component 23 starts to drive the drill rod 11 to move toward the end of the transmission bracket.

The linkage mechanism ensures that the second moving parts arranged on the multiple sub-transmission brackets move at the same speed and direction at the same time, avoiding the jamming or tilting of the drill rod caused by asynchrony, making the drill rod transmission process smoother, reducing the vibration caused by excessive force on a single point, ensuring the smoothness of the transmission of the drill rod 11, and the number and linkage mode of the transmission bracket and the lifting bracket 12 can be adjusted according to actual needs to adapt to transmission tasks of different lengths and types, and has a wide range of applicability.

[0062] In addition, each sub-transmission bracket is composed of a second bracket body 211 and a second transmission member 212. The second transmission member 212 is constructed to be a plurality of second bracket bodies 211 arranged one by one. Each second transmission member 212 is arranged around the outer periphery of the second bracket body 211 arranged corresponding to it. A plurality of second movable parts are arranged at intervals on the second transmission member 212. A drill rod 11 is placed between two adjacent second movable parts. An output shaft is arranged on the third driving member 35. The output shaft is connected to the second transmission member 212. The output shaft rotates to drive the second transmission member 212 to move. When the second transmission member 212 moves, the second movable part contacts with the drill rod 11. The second movable part is suitable for pushing the drill rod 11 from the starting end of the transmission bracket toward the end of the transmission bracket, thereby realizing the transmission of the drill rod 11 to the designated operation.

[0063] The electric arc furnace unloading robot equipment involved in the present application includes a chassis, an operating arm and an eye-pulling device. The operating arm is movably arranged on the chassis, and the operating arm is suitable for moving laterally on the chassis; the eye-pulling device is arranged on the operating arm and moves with the operating arm to reciprocate between an initial position and a working position. The lateral movement of the operating arm on the chassis means that the operating arm can move left and right along the width direction of the chassis. The lateral movement of the operating arm on the chassis can drive the movement of the eye-pulling device, so that the eye-pulling device moves between the initial position and the working position. The initial position is the position of the eye-pulling device before preparing to perform the unloading operation, and the working position is the position of the eye-pulling device to perform the unloading operation. The eye-pulling device is provided with a first mounting portion for clamping a drill rod 11; the drill rod transmission device 100 is arranged on one side of the eye-pulling device, and the drill rod transmission device 100 is responsible for automatically delivering a new drill rod 11 into the first mounting portion of the eye-pulling device for subsequent unloading operations.
