Description

Technical Field

[0001] The invention relates to the technical field of blast furnace charge cars, in particular to a traction-type blast furnace charge car. Background Art

[0002] The two main ways of charging blast furnaces are charge car and belt charging. Charge car requires less investment and occupies less area, and is widely used in small and medium-sized blast furnaces. However, during the charge car receiving process, the weighing bucket discharges the material into the charge car, which raises a lot of dust and pollutes the environment. In order to control the dust generated during the charge car transportation operation, some domestic steel companies use color steel or other light materials to seal the inclined bridge for the charge car. This has high cost, great implementation difficulty, long construction period, and also adds a lot of extra costs to the blast furnace charge transport inclined bridge.

[0003] In this regard, China has applied for patent number: CN201610699809.7, which discloses a blast furnace charge car with a self-moving cover. It includes a car body and wheels. It also includes two left and right shafts and a cover. The lower ends of the two shafts are hinged to the left and right outer walls of the car body respectively, the upper and middle parts are rigidly connected to the cover, and the upper ends are passed through steel wire ropes. The cover is covered on the car body, and the wheels are installed on the car body. Among them, the shape of the shaft is roughly U-shaped, the closed end at the bottom is hinged to the car body 1 through a pin shaft, etc., and a hole is opened at the upper end, and the steel wire rope passes through the middle. The blast furnace charge car of this invention can close the cover of the charge car during the charge car receiving and loading process, effectively preventing dust and spilling of furnace charge. In rainy and snowy weather, it also prevents rain and snow from entering the charge car. At the same time, the charge car cover can be opened before the charge car is unloaded, which does not affect the unloading of the charge car.

[0004] The blast furnace charge car is provided with a rotatable car cover to seal the car body, and a feed port is opened on the car cover to facilitate the weighing bucket to unload into the car body. However, the car body moves in an inclined manner, and the position of the weighing bucket is fixed. Therefore, the size of the feed port must be much larger than the size of the weighing bucket so that the weighing bucket can be inserted into the feed port. Therefore, during actual unloading, a large amount of dust will float out from the gap between the feed port and the weighing bucket, polluting the equipment and the environment. The company needs to clean it up at regular intervals, which greatly wastes human resources.

[0005] Therefore, in order to solve the above problems, a traction type blast furnace charging car is proposed. Summary of the Invention

Therefore, the size of the feed port must be much larger than the size of the weighing bucket so that the weighing bucket can be inserted into the feed port. Therefore, during actual unloading, a large amount of dust will float out from the gap between the feed port and the weighing bucket, polluting the equipment and the environment.

[0012] Preferably, the rubber sleeve is arranged on the outside of the discharge pipe, and one end of the gear penetrates the surface of the annular block and engages with the meshing teeth.

[0013] Preferably, the annular block is sleeved on the outside of the rubber sleeve, the two sets of winding discs are symmetrically installed on both sides of the inside of the annular block, the coil spring is sleeved on the outside of the winding disc, and the end is fixedly connected to the inner wall of the rotating ring.

[0014] Preferably, the end of the steel wire rope passes through the annular block via a sliding groove, and the end of the steel wire rope is fixedly connected to the inner wall of the tightening groove.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the rubber sleeve provided in the device of the present invention can be sleeved on the outside of the discharge pipe, and a rotatable winding disk is provided on the outside of the rubber sleeve, which can wrap the wire rope around the surface of the tightening groove so that the opening of the rubber sleeve is tied to the surface of the discharge pipe, so as to seal the connection between the rubber sleeve and the discharge pipe, reduce the flying of dust and materials, and improve the user experience of the device.

[0016] A shielding structure and a sealing structure are provided. When unloading, the bottom end of the discharge pipe is inserted into the inner side of the rubber sleeve, and the motor is started to drive the gear to rotate. The gear is meshed with the teeth, and the rotation of the gear drives the rotating ring to rotate inside the annular block through the teeth. When the rotating ring rotates, it drives the two sets of winding discs to move in a circular motion inside the annular block, and one end of the wire rope wound on the winding disc is connected to the surface of the tightening groove. When the winding disc moves in a circular motion, it pulls the wire rope, and the wire rope pulls the rubber sleeve, so that the rubber sleeve fits the outer wall of the discharge pipe, and the wire rope is wound around the surface of the tightening groove to seal the gap between the rubber sleeve and the discharge pipe. The gap is formed, and the wire rope is released from the reel, causing the reel to rotate. The rotation of the reel drives the coil spring to undergo elastic deformation, and the coil spring reacts on the wire rope to straighten the wire rope, thereby ensuring the pulling effect of the wire rope on the rubber sleeve and improving the sealing performance of the rubber sleeve on the discharge pipe. Then the material in the weighing hopper can be transported into the vehicle body through the discharge pipe and the rubber sleeve. The buffer plate can prevent the material from directly hitting the inner wall of the flip cover. After being impacted by the material, the buffer plate will deflect and push the telescopic rod, causing the telescopic rod to retract into the inner side of the fixed rod. The telescopic rod will squeeze when it moves. The spring can slow down the swinging trend of the buffer plate, prevent the buffer plate from hitting the inner wall of the flap, extend the service life of the flap, reduce the flying of dust and materials, and improve the user experience of the device; after unloading is completed, the motor is controlled to reverse, which can drive the annular block and the reel to reverse, and the reel reverses itself under the restoring force of the coil spring, and the reel can rewind the wire rope, which can release the squeeze on the rubber sleeve, and the rubber sleeve can recover under its own elasticity. The hoisting device is started to rewind the traction rope, and the traction block can be pulled to pull the car body on the track through the rotating arm. After moving to the upper end of the track, the car body will rotate. The rotating arm rotates on the vehicle body, and the rotating arm and the traction block drive the flap to slide upward on the outside of the arc frame through the arc groove, so that the flap rotates in the circumferential direction, which can drive the flap to move away from the opening of the vehicle body, so that the interior of the vehicle body is unobstructed, which is convenient for pouring out the materials in the vehicle body; start the winch equipment to lengthen the traction rope, the vehicle body can slide downward on the track, and at the same time the flap will slide on the arc frame through the arc groove, and the flap will fit the opening of the vehicle body to seal the opening.

[0021] A traction-type blast furnace skip car, comprising: a car body 1, a rotating arm 11 mounted on the front and rear walls of the car body 1, a traction block 12 disposed at the end of the rotating arm 11, a weighing bucket 13 disposed on one side of the car body 1, and a discharge pipe 14 disposed at the bottom end of the weighing bucket 13; A shielding structure 2 is installed on the rotating arm 11. The shielding structure 2 includes a flip cover 21, which is fixedly installed at the end of the rotating arm 11. Arc grooves 22 are provided on the left and right side walls of the flip cover 21. A buffer plate 23 is movably installed on the inner wall of the flip cover 21 through a bearing. A telescopic rod 24 is fixedly connected to the left wall of the buffer plate 23. A spring 25 is fixedly connected to the end of the telescopic rod 24. A fixing rod 26 is sleeved on the outer side of the end of the telescopic rod 24. A feeding port 27 is provided on the right side wall of the flip cover 21. A support arm 28 is fixedly installed on the top surface of the vehicle body 1. The end of the support arm 28 is fixedly connected to an arc frame 29. A sealing structure 3 is installed on the flip cover 21. The sealing structure 3 includes a rubber sleeve 31. The rubber sleeve 31 is fixedly installed on the right side wall of the flip cover 21 by rivets. The rubber sleeve 31 can be sleeved on the outside of the discharge pipe 14, and a rotatable winding disk 39 is provided on the outside of the rubber sleeve 31. The steel wire rope 311 can be wound around the surface of the tightening groove 32 so that the opening of the rubber sleeve 31 is tied to the surface of the discharge pipe 14 to seal the connection between the rubber sleeve 31 and the discharge pipe 14, reduce the flying of dust and materials, and improve the user experience of the device.

[0022] Furthermore, a tightening groove 32 is provided on the outer wall of the rubber sleeve 31, a motor 33 is fixedly installed on the top surface of the flip cover 21, and a gear 34 is fixedly connected to the output end of the motor 33. An annular block 35 is fixedly installed on the right side wall of the flip cover 21, and a slide groove 36 is provided on the inner wall of the annular block 35. A rotating ring 37 is movably installed on the inner side of the annular block 35 through a bearing, and meshing teeth 38 are welded on the outer wall of the rotating ring 37. Two sets of winding discs 39 are movably installed on the inner side of the rotating ring 37 through a rotating shaft. Coil springs 310 are fixedly connected to both ends of the winding disc 39, and a steel wire rope 311 is wound around the middle of the winding disc 39. The steel wire rope 311 can be wound around the outside of the rubber sleeve 31 so that the rubber sleeve 31 fits tightly against the outer wall of the discharge pipe 14 to seal between the rubber sleeve 31 and the discharge pipe 14, reduce the flying of dust and materials, and improve the user experience of the device.

[0023] Furthermore, the flip cover 21 is located at the opening of the vehicle body 1, the bottom surface of the flip cover 21 contacts the surface of the vehicle body 1, and the contact surface is arc-shaped. The buffer plate 23 is located on one side of the feed port 27. The flip cover 21 can block the opening of the vehicle body 1 to prevent rain and snow from entering the vehicle body 1 and limit the flying of dust and materials. The setting of the buffer plate 23 can prevent the material from directly hitting the inner wall of the flip cover 21.

[0024] Furthermore, the telescopic rod 24 and the fixed rod 26 are both arc-shaped, and the telescopic rod 24 and the fixed rod 26 are coaxially arranged with the buffer plate 23. One end of the fixed rod 26 is fixedly connected to the inner wall of the flip cover 21, and one end of the spring 25 is fixedly connected to the inner wall of the fixed rod 26. When the buffer plate 23 moves, it can push the telescopic rod 24 to retract into the fixed rod 26. The setting of the spring 25 can reduce the tendency of the buffer plate 23 to move, thereby achieving buffering.

[0025] Furthermore, the arc frame 29 is arc-shaped, and the arc frame 29 passes through the flip cover 21 through the arc groove 22. One end of the arc frame 29 is fixedly connected to the vehicle body 1. The arc frame 29 is coaxially arranged with the rotating arm 11. When the rotating arm 11 swings, it can drive the flip cover 21 to slide on the arc frame 29 through the arc groove 22, so that the installation of the flip cover 21 on the vehicle body 1 is smooth and convenient, and the flip cover 21 can be opened and closed.

[0026] Furthermore, the rubber sleeve 31 is sleeved on the outside of the discharge pipe 14, one end of the gear 34 passes through the surface of the annular block 35 and engages with the teeth 38. The material unloaded through the discharge pipe 14 can enter the flip cover 21 through the feed port 27, and the rotation of the gear 34 can drive the rotating ring 37 to rotate inside the annular block 35 through the teeth 38.

[0027] Furthermore, the annular block 35 is sleeved on the outside of the rubber sleeve 31, and two sets of winding disks 39 are symmetrically installed on both sides of the inside of the annular block 35. The coil spring 310 is sleeved on the outside of the winding disk 39, and the end is fixedly connected to the inner wall of the rotating ring 37. The rotating ring 37 can rotate on the outside of the rubber sleeve 31, so that the winding disk 39 can move in a circle on the outside of the rubber sleeve 31. The coil spring 310 provides power for the wire rope 311 to pull the winding disk 39 to rotate, so that the wire rope 311 is straightened, and the winding disk 39 can reel in the wire rope 311.

[0028] Furthermore, the end of the wire rope 311 passes through the annular block 35 via the slide groove 36, and the end of the wire rope 311 is fixedly connected to the inner wall of the tightening groove 32. When the winding drum 39 drives the wire rope 311 to move in a circular motion, the rubber sleeve 31 can be pulled by the wire rope 311, so that the rubber sleeve 31 fits the outer wall of the discharge pipe 14 and can be wound on the outer wall of the rubber sleeve 31, thereby achieving a sealed fit of the rubber sleeve 31 on the outer wall of the discharge pipe 14.

[0029] The working principle is as follows: when unloading, the bottom end of the discharge tube 14 is inserted into the inner side of the rubber sleeve 31, and the motor 33 is started to drive the gear 34 to rotate. The gear 34 meshes with the meshing teeth 38. The rotation of the gear 34 drives the rotating ring 37 to rotate inside the annular block 35 through the meshing teeth 38. When the rotating ring 37 rotates, it drives the two sets of take-up discs 39 to move in a circular motion inside the annular block 35, and one end of the wire rope 311 wound on the take-up disc 39 is connected to the surface of the tightening groove 32. When the take-up disc 39 moves in a circular motion, it pulls the wire rope 311, and the wire rope 311 pulls the rubber sleeve 31, so that the rubber sleeve 31 fits the outer wall of the discharge tube 14, and the wire rope 311 is wound around the surface of the tightening groove 32 to block the gap between the rubber sleeve 31 and the discharge tube 14. At the same time, the wire rope 311 is lengthened from the take-up disc 39, causing the take-up disc 39 to rotate and the take-up is wound. The rotation of the disk 39 will drive the coil spring 310 to undergo elastic deformation, and the coil spring 310 will react on the wire rope 311 to straighten the wire rope 311, thereby ensuring the pulling effect of the wire rope 311 on the rubber sleeve 31 and improving the sealing performance of the rubber sleeve 31 on the discharge pipe 14. Then the material in the weighing bucket 13 can be transported into the vehicle body 1 through the discharge pipe 14 and the rubber sleeve 31. The setting of the buffer plate 23 can prevent the material from directly hitting the inner wall of the flip cover 21. After being impacted by the material, the buffer plate 23 will deflect and push the telescopic rod 24, so that the telescopic rod 24 is retracted to the inner side of the fixed rod 26. The telescopic rod 24 will squeeze the spring 25 when it moves, which can slow down the swinging trend of the buffer plate 23 and prevent the buffer plate 23 from hitting the inner wall of the flip cover 21, thereby extending the service life of the flip cover 21, reducing the flying of dust and materials, and improving the user experience of the device. After unloading is completed, the motor 33 is controlled to reverse, which can drive the annular block 35 and the winding drum 39 to reverse. The winding drum 39 reverses itself under the restoring force of the winding spring 310, and the winding drum 39 can reel in the wire rope 311, thereby releasing the squeeze on the rubber sleeve 31, and the rubber sleeve 31 can recover under its own elastic action. The hoisting device is started to reel in the traction rope, and the traction block 12 can be pulled to pull the car body 1 to move on the track through the rotating arm 11. After moving to the upper end of the track, the car body 1 will rotate, and the rotating arm 11 will rotate on the car body 1. The rotating arm 11 and the traction block 12 will drive the flip cover 21 to slide upward on the outer side of the arc frame 29 through the arc groove 22, so that the flip cover 21 rotates in the circumferential direction, which can drive the flip cover 21 to move away from the opening of the car body 1, so that the interior of the car body 1 is unobstructed, which is convenient for pouring out the materials in the car body 1. Start the winch device to lengthen the traction rope, and the vehicle body 1 can slide downward on the track. At the same time, the flip cover 21 will slide on the arc frame 29 through the arc groove 22. The flip cover 21 will fit the opening of the vehicle body 1 and seal the opening. When the vehicle body 1 moves to the bottom end of the track, the rubber sleeve 31 will be sleeved on the outside of the discharge pipe 14. At this time, the motor 33 can be started to repeat the above work.
