Description

Technical Field

[0001] The invention relates to a metallurgical slag ladle operating vehicle, in particular to a rail-grabbing type metallurgical slag ladle operating vehicle. Background Art

[0002] Nonferrous metals such as copper will produce residues during the smelting process. The residues need to be transported from the smelting furnace to an outdoor open-air environment or other residue slow cooling area, and the residue temperature is cooled from 700 to 800 degrees to room temperature through various methods. The residue is then dumped out for subsequent processing.

[0003] Currently, there are two ways to transport the residue to the residue slow cooling area and dump the residue on the market:

[0004] The first method is to use a gantry crane hook to lift the slag bag from the slag bag transport vehicle, place it in the designated slag bag slow cooling area to wait for the residue to cool, and then lift the slag bag to the slag dumping area. The gantry crane's large and small hooks work together to realize the bag turning process. However, the use of a gantry crane hook has the following disadvantages:

[0005] 1. The cost of the gantry crane hook itself is as high as one million, and the residue slow cooling area occupies a large area in the outdoor open air environment, which leads to a large span of the gantry crane hook, which greatly increases the cost;

[0006] 2. Since the gantry crane hook bag turning action is difficult, it has high requirements for operators, which greatly increases the investment cost;

[0007] 3. The gantry crane hook has a low flipping angle, generally not exceeding 90 degrees. The low flipping angle will result in unclean dumping of the residue, and manual mechanical cleaning is still required after each dumping, which increases the processing cost;

[0008] 4. Because the gantry crane is operated outdoors, it is greatly affected by the outside world. If it encounters a strong wind of level 6 or above, the gantry crane must stop operating, thus affecting the progress;

[0009] 5. The operation mode of the gantry hook cannot achieve intelligent and unmanned operation, which will lead to reduced efficiency and increased costs;

[0010] The second method is to use a large-tonnage tank-carrying truck to pick up the slag bag from the slag bag transport vehicle, put it in the designated slag bag slow cooling area to wait for the residue to cool down, and then carry the slag bag to the slag dumping area to complete the bag turning process through its own mechanism. However, the use of large-tonnage tank-carrying trucks has the following disadvantages:

[0011] 1. Each tank-carrying truck itself costs up to one million yuan. In the actual residue treatment process, multiple tank-carrying trucks are required to operate, so the investment cost is relatively high;

[0012] 2. For each additional tank truck, the number of related personnel will also increase, which will greatly increase the cost of use;

[0013] 3. The maintenance and upkeep costs of tank cars in the middle and later stages are high, and as the years of use increase, the maintenance costs also increase;

[0014] 4. The operation mode of the tank truck cannot achieve intelligent and unmanned operation, which will lead to reduced efficiency and increased costs. Summary of the invention

[0015] In order to solve the problems in the related technology, the present application provides a rail-grabbing metallurgical slag ladle operating vehicle, which solves the problems of high cost, difficult operation, safety hazards, unclean residue dumping and low processing efficiency.

[0016] The technical solution is as follows:

[0017] A rail-grabbing metallurgical slag ladle operation vehicle, comprising a vehicle frame, a travel driving wheel set for driving the vehicle frame to move along a steel rail is arranged at the bottom of the vehicle frame, large rotating arms are hinged on both sides of one end of the vehicle frame, the two large rotating arms are arranged symmetrically, and a fork head for forking the slag ladle ear shaft is arranged at the top of the large rotating arm, which is characterized in that first driving mechanisms for driving the large rotating arms to rotate along the vertical plane where the hinged position is located are fixed on both sides of the other end of the vehicle frame, and the two first driving mechanisms are arranged symmetrically;

[0018] The frame is provided with four rail grabbers at the bottom; the rail grabbers include rail grabber blocks arranged on both sides of the rail and a pushing oil cylinder fixed on the frame, and the two rail grabber blocks are arranged symmetrically, and the two rail grabber blocks are both rotatably matched with the frame, and the bottom ends of the two rail grabber blocks are provided with grippers for gripping the rails, and the thickness of each gripper is smaller than the groove width of the corresponding groove on the side of the rail, and the two rail grabber blocks are connected by a reset spring, and the reset spring is arranged above the hinge between the rail grabber block and the frame; the piston rod of the pushing oil cylinder is provided with a support block, and the support block is slidably arranged between the two rail grabber blocks;

[0019] When the push cylinder pushes the support block downward until the support block abuts against the rail, the grippers of the two rail grabbing blocks respectively abut against the bottom of the grooves on the corresponding side edges of the rail, so that the rail grabber can withstand both pressure and tension.

[0020] Through the above technical scheme, through the setting of the rail grabber, when the slag bag operating vehicle is in different working states, the pressure and tension of the rail grabbers at different positions are different, that is, the pressure and tension at different positions are constantly switching. For example, when the slag bag is taken off the slag bag transport vehicle, the two rail grabbers on the side away from the slag bag will be subjected to a relatively large tension, and the two rail grabbers on the side close to the slag bag will be subjected to a huge pressure. At this time, because the support block is against the top of the rail, the pressure can be transmitted to the rail. Because the two clamping grips of each rail grabber clamp the rail respectively, they can withstand the tension. Even if the two clamping grips move downward respectively under the action of pressure, because the thickness of the clamping grip is less than the groove width of the groove on the side of the rail, the clamping grip can move in the groove at this time to ensure that the tension will not be affected, thereby effectively ensuring the stability of the frame, thereby ensuring the safety of the residue treatment process;

[0021] Through the setting of the travel driving wheel group, during the movement of the frame, the travel driving wheel group moves in a straight line on the load-bearing rail, and then the power supply of the frame can be provided by the busbar, and ordinary industrial electricity is used, which is more energy-saving and environmentally friendly. It only needs to be treated with rain and snow protection at the power supply point and drainage treatment at the rail foundation. Even in severe weather such as rain, snow and strong wind, the equipment can still operate normally, thereby improving processing efficiency and reducing costs;

[0022] The movement of the frame, the transfer of the slag bag driven by the large rotating arm, and the loosening and clamping of the rail grabber can all be controlled remotely, thereby realizing unmanned automatic operation, thereby reducing labor costs; and because of unmanned operation, even if a fault or major accident occurs during the residue treatment process, it will not affect the safety of personnel.

[0023] Furthermore, a limiting protrusion is integrally formed on the rail grabbing block corresponding to each of the clamping grasps, each limiting protrusion protrudes toward the direction of the rail, and notches are provided on both sides of the support block close to the rail grabbing block, each notch is recessed toward the direction of the vertical center line of the rail, and the shape of each notch is suitable for the limiting protrusion;

[0024] The two rail grabbing blocks are arranged in an inclined shape so that the distance between the two rail grabbing blocks decreases from top to bottom. The two side surfaces of the support block respectively close to the corresponding rail grabbing blocks are arranged in an inclined shape, and the top width value of the support block is greater than the width value between the bottoms of the two rail grabbing blocks.

[0025] Through the above technical solution, by setting the limiting protrusion and the notch, when the rail grabber is controlled to clamp the rail, the limiting protrusion moves into the notch, thereby limiting the rail grabbing block, thereby improving the stability of the frame.

[0026] Furthermore, the first driving mechanism includes a lifting cylinder, the output shaft of the lifting cylinder is hingedly matched with the middle part of the corresponding large swing arm, and the lifting cylinder is used to drive the large swing arm to rotate along its bottom end so that the angle between the large swing arm and the frame is between 0° and 125°.

[0027] Through the above technical scheme, through the cooperation of the large rotating arm and the lifting cylinder, when the residue is processed, the large rotating arm is driven by the first driving mechanism to rotate along the hinge at the bottom end of the large rotating arm, and when the fork at the top of the large rotating arm rotates to the ear axis of the slag bag and stops, after the fork forks the ear axis of the slag bag, the large rotating arm is driven to rotate by the first driving mechanism, and then the slag bag is moved away from its original position. The structure is simple and the operation is convenient, which can reduce maintenance costs and labor costs. Because the connection between the first driving mechanism and the large rotating arm is in the middle of the large rotating arm, the first driving mechanism can drive the slag bag on the fork to flip at a maximum angle of 125°, which can completely dump the residue in the slag bag, thereby improving the processing efficiency and reducing costs.

[0028] Furthermore, the frame includes a lower frame, a rotating frame and an upper frame; the rotating frame is rotatably arranged on the top of the lower frame, and the lower frame is provided with a rotating driving device for driving the rotating frame to rotate; the upper frame is slidably arranged above the rotating frame, and the rotating frame is provided with a second driving mechanism for driving the upper frame to move along the travel direction of the lower frame.

[0029] Furthermore, a bag-turning locking cylinder is provided at one end of each of the large rotating arms close to the fork head; when the lifting cylinder drives the slag bag to move so that the ear axis of the slag bag is in a vertical state, the bag-turning locking cylinder is started, so that the output shaft of the bag-turning locking cylinder extends out and contacts the flip limit plate in the slag bag.

[0030] Through the above technical solution, by setting the turning bag locking cylinder, the turning limit plate on the slag bag can be locked through its output shaft, thereby ensuring the stability of the slag bag during the rotation of the slag bag, thereby improving the safety of the residue treatment process.

[0031] Furthermore, the second driving mechanism includes a transverse oil cylinder fixedly arranged on the top of the revolving frame, and the transverse oil cylinder is arranged in the middle position of the revolving frame, and the piston rod of the transverse oil cylinder is fixedly matched with the upper frame.

[0032] Furthermore, a transverse wheel group is symmetrically arranged at the bottom end of the upper frame, and each transverse wheel group is in rolling cooperation with the revolving frame.

[0033] Through the above technical solution, by setting the transverse wheel group, the frame position can be fine-tuned according to the actual placement position, thereby speeding up the progress of taking or placing the slag bag, thereby improving the residue processing efficiency and reducing time costs.

[0034] Furthermore, the rotary drive device includes a reduction motor and a gear arranged above the reduction motor, the gear is sleeved on the output shaft of the reduction motor, and the central axis of the gear is arranged vertically;

[0035] A slewing bearing is arranged at the middle of the top end of the lower frame, the central axis of the slewing bearing is arranged vertically, and the slewing bearing is an external gear slewing bearing, and the outer periphery of the slewing bearing is meshed with the gear.

[0036] Through the above technical solution, by setting up the external tooth slewing bearing, when the fork grabs the slag bag and removes it from the slag bag transport vehicle, the slewing bearing can be driven to rotate by controlling the reduction motor, and then the slag bag can be driven to adjust to the top of other areas. The structure is simple and the operation is quick, thereby speeding up the residue treatment efficiency and reducing costs.

[0037] In summary, the beneficial effects of a rail-grabbing metallurgical slag ladle operating vehicle are:

[0038] 1. Through the setting of the rail grabber, when the slag bag handling vehicle is in different working states, the pressure and tension of the rail grabbers at different positions are different, that is, the pressure and tension at different positions are constantly switching. For example, when the slag bag is taken off the slag bag transport vehicle, the two rail grabbers on the side away from the slag bag will be subjected to a relatively large tension, and the two rail grabbers on the side close to the slag bag will be subjected to huge pressure. At this time, because the support block is against the top of the rail, the pressure can be transmitted to the rail. Because the two clamps of each rail grabber clamp the rail respectively, it can withstand the tension, thereby effectively ensuring the stability of the frame, thereby ensuring the safety of the residue treatment process;

[0039] Through the setting of the travel driving wheel group, during the movement of the frame, the travel driving wheel group moves in a straight line on the load-bearing rail, and then the power supply of the frame can be provided by the busbar, and ordinary industrial electricity is used, which is more energy-saving and environmentally friendly. It only needs to be treated with rain and snow protection at the power supply point and drainage treatment at the rail foundation. Even in severe weather such as rain, snow and strong wind, the equipment can still operate normally, thereby improving processing efficiency and reducing costs;

[0040] Through the cooperation of the large swing arm and the lifting cylinder, when the residue is processed, the large swing arm is driven by the first driving mechanism to rotate along the hinge at the bottom end of the large swing arm. When the fork at the top of the large swing arm rotates to the ear axis of the slag bag and stops, after the fork forks the ear axis of the slag bag, the large swing arm is driven to rotate by the first driving mechanism, and then the slag bag is moved away from its original position. The structure is simple and the operation is convenient, which can reduce maintenance costs and labor costs. Because the connection between the first driving mechanism and the large swing arm is in the middle of the large swing arm, the first driving mechanism can drive the slag bag on the fork to flip at a maximum angle of 125°, which can completely dump the residue in the slag bag, thereby improving the processing efficiency and reducing costs; the movement of the frame, the transfer of the slag bag driven by the large swing arm, and the loosening and clamping of the track grabber can all be remotely controlled, thereby realizing unmanned automatic operation, thereby reducing labor costs; and because of unmanned operation, even if a fault or major accident occurs during the residue processing process, it will not involve the safety of personnel.

[0041] 2. Through the setting of the turning and locking cylinder, the turning limit plate on the slag bag can be locked through its output shaft, thereby ensuring the stability of the slag bag during the rotation of the slag bag, thereby improving the safety of the residue treatment process;

[0042] 2. By setting the transverse wheel group, the frame position can be fine-tuned according to the actual placement position, thereby speeding up the progress of taking or placing the slag bag, thereby improving the residue processing efficiency and reducing time cost;

[0043] 3. Through the setting of the external gear slewing bearing, when the fork grabs the slag bag and removes it from the slag bag transport vehicle, the slewing bearing can be driven to rotate by controlling the reduction motor, and then the slag bag can be driven to adjust to the top of other areas. The structure is simple and the operation is fast, which can speed up the residue treatment efficiency and reduce costs.

DETAILED DESCRIPTION

[0056] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0057] In a possible embodiment, as shown in the attached Figure 1-9As shown, a rail-grabbing metallurgical slag ladle operation vehicle comprises a frame 1, and a travel driving wheel group 2 for driving the frame 1 to move along the rail is arranged at the bottom of the frame 1. In this specific embodiment, the travel driving wheel group 2 comprises a driving wheel group and a driven wheel group, and the driving wheel group and the driven wheel group are arranged at intervals at the front end and the rear end of the frame 1. The driving wheel group and the driven wheel group respectively include a first wheel group and a second wheel group, and the first wheel group and the second wheel group each include two wheels with the same structure and connected by a connecting rod. One wheel in the first wheel group is connected to a driving assembly, and the driving assembly is used to drive the first wheel group to rotate so that the frame 1 moves along the rail. The rails roll, and the specific structure and installation method of the walking driving wheel set 2 belong to the prior art, which will not be described in detail here. A model that can drive the frame 1 to walk in a straight line on the rails can be selected, which will not be described in detail here. During the movement of the frame 1, the walking driving wheel set 2 walks in a straight line on the load-bearing rails, and then the frame 1 can be provided with power supply through the power supply method of the busbar, and ordinary industrial electricity is used, which is more energy-saving and environmentally friendly. It only needs to be treated with rain and snow at the power supply point, and the rail foundation needs to be treated with drainage. Even in severe weather such as rain, snow and strong wind, the equipment can still operate normally, thereby improving processing efficiency and reducing costs.

[0058] Both sides of one end of the frame 1 are hinged with large rotating arms 3, and the two large rotating arms 3 are symmetrically arranged. The top of the large rotating arms 3 is provided with a fork head 4 for forking the ear shaft of the slag ladle; both sides of the other end of the frame 1 are fixed with a first driving mechanism 5 for driving the large rotating arms 3 to rotate along the vertical plane where the bottom end of the large rotating arms 3 is hinged. The two first driving mechanisms 5 are symmetrically arranged. The first driving mechanism 5 includes a lifting cylinder, and the output shaft of the lifting cylinder is hinged with the middle part of the corresponding large rotating arm 3. The lifting cylinder is used to drive the corresponding large rotating arm 3 to rotate along its bottom end, so that the angle between the large rotating arm 3 and the corresponding frame 1 is between 0° and 125°.

[0059] When treating residue, the large rotating arm 3 is driven by the first driving mechanism 5 to rotate along the bottom hinge of the large rotating arm 3. When the fork 4 at the top of the large rotating arm 3 rotates to the ear axis of the slag bag and stops, after the fork 4 forks the ear axis of the slag bag, the large rotating arm 3 is driven to rotate by the first driving mechanism 5, and then the slag bag is moved away from its original position. The structure is simple and the operation is convenient, which can reduce maintenance costs and labor costs. Because the connection between the first driving mechanism 5 and the large rotating arm 3 is in the middle of the large rotating arm 3, the first driving mechanism 5 can drive the slag bag on the fork 4 to flip at an angle of 125°, which can completely dump the residue in the slag bag, thereby improving the treatment efficiency and reducing costs.

[0060] Four rail grabbers 6 are arranged at the bottom of the frame 1; the rail grabber 6 includes rail grab blocks 602 arranged on both sides of the rail and a pushing cylinder 601 fixed on the frame 1, and the two rail grab blocks 602 are arranged symmetrically, and the two rail grab blocks 602 are both rotatably matched with the frame 1, and the bottom ends of the two rail grab blocks 602 are each provided with a clamping grip 9 for grasping the rail, and the thickness value of each clamping grip 9 is smaller than the groove width value of the corresponding groove on the side of the rail, and the two rail grab blocks are connected by a reset spring 8, and the reset spring 8 is arranged above the hinge between the rail grab block 602 and the frame 1; the piston rod of the pushing cylinder 601 is provided with a support block 10, and the support block 10 is slidably arranged between the two rail grab blocks 602;

[0061] Each rail grabber 6 is adaptively arranged on the rail. The adaptive shape means that the hydraulic system in the rail grabber cylinder is adjusted according to the state of the force bearing of the rail grabber. For example, when the rail grabber is under pressure, the push cylinder pushes the support block downward so that it rests against the top of the rail. After the pressure is transmitted to the rail, the rail will generate a reaction force. At this time, it is necessary to control the hydraulic system of the push cylinder to ensure that the support block always rests against the top of the rail; when the rail grabber is under tension, the push cylinder does not need to additionally control its hydraulic system, because at this time the rail does not generate any reaction force on the rail grabber.

[0062] A limiting protrusion 16 is integrally formed on the corresponding rail grabbing block 602 above each grab 9, and each limiting protrusion 16 protrudes in the direction of the rail. A pin is set on the limiting protrusion 16 in each rail grabbing block to achieve rotational cooperation with the frame. The specific connection method between the rail grabbing block and the frame is common knowledge and will not be elaborated here. Notches 17 are set on both sides of the support block 10 near the rail grabbing block 602, and each notch 17 is recessed in the direction of the vertical center line of the rail, and the shape of each notch 17 is suitable for the limiting protrusion 16; when the rail grabber 6 is controlled to clamp the rail, the limiting protrusion 16 moves into the notch 17, thereby limiting the rail grabbing block 602, thereby improving the stability of the frame 1.

[0063] The two rail grabbing blocks 602 are both arranged in an inclined shape, so that the distance between the two rail grabbing blocks 602 decreases from top to bottom, and the two side surfaces of the support block close to the corresponding rail grabbing blocks are both arranged in an inclined shape, and the top width value of the support block is greater than the width value between the bottoms of the two rail grabbing blocks.

[0064] When the push cylinder 601 pushes the support block 10 downward until the support block 10 abuts against the rail, the grippers 9 of the two rail grabbing blocks 602 abut against the bottom of the grooves of the corresponding side edges of the rail, so that the rail grabber 6 bears both pressure and tension.

[0065] When the slag bag is taken to the slag bag handling vehicle, the two rail grabbers 6 on one side of the slag bag handling vehicle close to the slag bag are subjected to pressure, and the two rail grabbers 6 on the other side of the slag bag handling vehicle are subjected to tension;

[0066] When the slag bag is placed on the slag bag handling vehicle, the four rail grabbers 6 are under pressure;

[0067] When the slag bag is lowered from the slag bag handling vehicle, the two rail grabbers 6 on one side of the slag bag handling vehicle close to the actual placement of the slag bag are subjected to pressure, and the two rail grabbers 6 on the other side of the slag bag handling vehicle are subjected to tension;

[0068] When the fork 4 is controlled to perform the slag dumping operation on the slag bag, the two rail grabbers 6 on one side of the slag bag operation vehicle close to the slag bag are subjected to pressure, and the two rail grabbers 6 on the other side of the operation vehicle are subjected to tension.

[0069] When the slag bag operating vehicle is in different working states, the pressure and tension on the rail grabbers 6 at different positions are different, that is, the pressure and tension at different positions are constantly switching. For example, in the process of removing the slag bag from the slag bag transport vehicle, the two rail grabbers 6 on the side away from the slag bag will be subjected to relatively large tension, and the two rail grabbers 6 on the side close to the slag bag will be subjected to huge pressure. At this time, because the support block 10 is against the top of the rail, the pressure can be transmitted to the rail. Because the two clamping grips 9 of each rail grabber 6 clamp the rail respectively, they can withstand the tension. Even if the two clamping grips 9 move downward respectively under the action of pressure, because the thickness of the clamping grips 9 is less than the groove width of the groove on the side of the rail, the clamping grips 9 can move in the groove at this time to ensure that the tension will not be affected, thereby effectively ensuring the stability of the frame and thus ensuring the safety of the residue treatment process.

[0070] The frame 1 is provided with a control box 7 for remotely controlling the travel drive wheel set 2, the rail grabber 6 and the first drive mechanism 5, which belongs to the prior art and will not be described in detail here; the model of the control box 7 can be selected to be a model that can remotely control the travel drive wheel set 2, the rail grabber 6 and the first drive mechanism 5, and will not be described in detail here;

[0071] In this specific embodiment, remote control is achieved through a PLC controller in the control box 7, which is a conventional technical means that can be thought of by technicians in this field. The specific structure and connection method of the PLC controller are common knowledge. The PLC controller can be a model that can achieve remote control, and no further details will be given here.

[0072] The control box 7 can be used to remotely control the movement of the frame 1, the movement and rotation of the slag bag driven by the large rotating arm 3, and the loosening and clamping of the rail grabber 6, thereby realizing unmanned automatic operation, thereby reducing labor costs; and because of unmanned operation, even if a fault or major accident occurs during the residue treatment process, it will not affect the safety of personnel.

[0073] The frame 1 includes a lower frame 101, a revolving frame 102 and an upper frame 103; the revolving frame 102 is rotatably arranged on the top of the lower frame 101, and a revolving driving device 11 for driving the revolving frame 102 to rotate is arranged on the lower frame 101, and the revolving driving device 11 is connected to the control box 7; the upper frame 103 is slidably arranged above the revolving frame 102, and a second driving mechanism 12 for driving the upper frame 103 to move along the travel direction of the lower frame 101 is arranged on the revolving frame 102.

[0074] Each large rotating arm 3 is provided with a bag turning locking cylinder 13 at one end close to the fork head 4, and each bag turning locking cylinder 13 is connected to the control box 7; when the lifting cylinder drives the slag bag to move so that the ear axis of the slag bag is in a vertical state, the bag turning locking cylinder 13 is started, as shown in FIG. Figure 8 As shown, the left-side flipping and locking cylinder 13 is extended, and the right-side flipping and locking cylinder 13 is not extended yet. Fig. 9 As shown, at this time, the output shaft of the left-side turning bag locking cylinder 13 extends out to the turning limit plate in the slag bag. The turning limit plate in the slag bag is arranged in a "T" shape, and the horizontal section in the turning limit plate is arranged at the bottom of the vertical section. When the output shaft of the turning bag locking cylinder 13 is extended, the horizontal section and the vertical section in the turning limit plate are limited, thereby realizing the limitation of the slag bag, which ensures the stability of the slag bag during the rotation of the slag bag, thereby improving the safety of the residue treatment process.

[0075] The second driving mechanism 12 includes a transverse oil cylinder fixedly arranged on the top of the revolving frame 102 , and the transverse oil cylinder is arranged in the middle position of the revolving frame 102 , and the piston rod of the transverse oil cylinder is fixedly matched with the upper frame 103 .

[0076] The bottom end of the upper frame 103 is symmetrically provided with a transverse wheel group 14, and each transverse wheel group 14 is in rolling cooperation with the revolving frame 102; when it is necessary to fine-tune the position of the large swing arm 3, the transverse cylinder is controlled to start, and the moving position of the upper frame 103 is changed according to the actual adjustment position. In this process, the transverse wheel group 14 can speed up the progress of taking or placing the slag bag, thereby speeding up the residue processing efficiency and reducing the time cost.

[0077] The rotary drive device 11 includes a reduction motor 1101 and a gear 1102 disposed above the reduction motor 1101. The gear 1102 is sleeved on the output shaft of the reduction motor 1101, and the central axis of the gear 1102 is vertically disposed.

[0078] A slewing bearing 15 is arranged at the middle part of the top end of the lower frame 101. The central axis of the slewing bearing 15 is arranged vertically, and the slewing bearing 15 is an external gear slewing bearing 15. The outer periphery of the slewing bearing 15 and the gear 1102 are meshed. When the fork head 4 forks the slag bag to remove it from the slag bag transport vehicle, the slewing bearing 15 can be driven to rotate by controlling the reduction motor 1101, and then the slag bag can be driven to be adjusted to the top of other areas.

[0097] Step 36, control the ladle turning locking cylinder 13 to work, so that it locks the slag ladle turning limit plate, control the piston rod of the lifting cylinder to slowly extend, and slowly turn the slag ladle to 125 degrees. At this time, the slag ladle is in position four, the residue in the slag ladle is dumped out, and the ladle turning action is completed;

[0098] Step 37, control the piston rod of the lifting cylinder to fully retract, control the flipping and locking cylinder 13 to return, and control the four rail grabbers 6 to release.

[0099] Step 4: Transport the empty slag bag to the slag bag transport vehicle:

[0100] Step 41, drive the slag bag operation vehicle to the slag bag receiving position and stop accurately, and control the four rail grabbers 6 to grab the rails;

[0101] Step 42, control the slewing bearing 15 to drive the large slewing arm 3 to rotate 180 degrees, control the piston rod of the lifting cylinder to slowly extend, drive the large slewing arm 3 to drive the slag bag to move, and when the slag bag is placed on the ordinary slag bag transport vehicle, the lifting cylinder stops;

[0102] Step 43, control the piston rod of the transverse oil cylinder to fully extend, drive the transverse movement of the upper rotating arm, and when the fork 4 of the large rotating arm 3 is separated from the slag bag, the transverse oil cylinder stops;

[0103] Step 44, control the piston rod of the lifting cylinder to fully retract, control the piston rod of the traverse cylinder to fully retract, and control the four rail grabbers 6 to release them from the rails.
