[0020] See also Figure 1 - Figure 4 The utility model provides a technical solution: a discharging device for preventing pipes from falling when unloading, comprising a base 1, a telescopic cylinder 2 and a discharging platform 3. A telescopic cylinder 2 is arranged on one side of the upper surface of the base 1. The telescopic cylinder 2 can be lifted and lowered to facilitate adjusting the height of the discharging platform 3 so as to facilitate unloading of pipes of different heights. The discharging platform 3 is connected to the top of the telescopic cylinder 2 through a rotating shaft. The discharging platform 3 can rotate in the horizontal direction of the telescopic cylinder 2, so as to facilitate the tilted discharging operation. A fixing plate 4 is arranged on one side of the telescopic cylinder 2. The fixing plate 4 plays a fixing role. A screw 5 is connected to the middle part of the fixing plate 4 through a bearing. A servo motor 6 is connected to the side of the fixing plate 4 away from the screw 5. The output end of the servo motor 6 is connected to the screw 5, and the screw 5 can be driven to rotate by the servo motor 6.

[0021] The middle outer wall of the screw rod 5 is threadedly connected with a moving bar 7. The rotation of the screw rod 5 can drive the moving bar 7 to perform axial translation. The top two sides of the moving bar 7 are connected with push rods 8 through rotating shafts. The push rods 8 play a supporting and connecting role. The end of the push rod 8 away from the moving bar 7 is connected to the unloading platform 3 through the rotating shaft. The screw rod 5 can be driven to rotate by the servo motor 6. The rotation of the screw 5 can drive the moving bar 7 to perform axial translation. The movement of the moving bar 7 drives the bottom end of the push rod 8 to move, so that the push rod 8 is tilted, thereby adjusting one end of the unloading platform 3. The ends are tilted to facilitate unloading of the pipeline. Guardrails 9 are connected to the edges of both sides of the unloading platform 3. The guardrails 9 play a protective role to prevent the pipeline from falling from the side. The middle part of the guardrail 9 is connected to a sliding roller 10 through a bearing. The rotation of the sliding roller 10 can assist the movement of the pipeline to facilitate unloading. A movable groove 11 is provided in the middle of one side of the unloading platform 3. The movable groove 11 plays a limiting role. An extension plate 12 is embedded in the interior of the movable groove 11. The extension plate 12 plays an extension role to facilitate the adjustment of various slopes and can be connected to the unloading place.

[0022] A No. 2 screw 13 is connected to the bottom of the movable groove 11 through a bearing, and a moving block 14 is threadedly connected to the outer wall of the No. 2 screw 13. The top of the moving block 14 is connected to the extension plate 12 by bolts. A No. 2 servo motor 15 is arranged on the outer wall of the side of the unloading platform 3 away from the movable groove 11. The output end of the No. 2 servo motor 15 is connected to the No. 2 screw 13. The No. 2 servo motor 15 can drive the No. 2 screw 13 to rotate. The rotation of the No. 2 screw 13 drives the moving block 14 to perform axial translation. The movement of the moving block 14 drives the extension plate 12 to perform translation, thereby realizing the telescopic function of the extension plate 12, so that when facing unloading at different inclination angles, the extension plate 12 can be extended to ensure that the unloading work can be carried out, which is convenient for efficient pipeline unloading in various complex environments.

[0023] The top of one end of the extension plate 12 passing through the movable groove 11 is connected to a baffle 16 through a rotating shaft. The baffle 16 plays a blocking role to prevent the pipeline from sliding quickly from the unloading platform 3 and thus damaging or injuring the staff. An electric telescopic rod 17 is connected to the edge of one side of the extension plate 12 close to the baffle 16. The end of the electric telescopic rod 17 away from the extension plate 12 is connected to the baffle 16. Both ends of the electric telescopic rod 17 are movably connected to the extension plate 12 and the baffle 16 through a rotating shaft. The baffle 16 can be pushed to rotate along the rotating shaft by the electric telescopic rod 17 to cancel the obstruction to the pipeline, thereby facilitating the unloading of the pipeline.

[0024] A buffer mechanism 18 is arranged on the surface of one side of the baffle 16 close to the unloading platform. The buffer mechanism 18 plays a certain buffering role to prevent the pipeline from being damaged due to a certain impact force generated due to the rapid speed when the pipeline moves to the position of the baffle 16. The buffer mechanism 18 includes a fixed sleeve 19, a rebound column 20, a connecting frame 21, a support spring 22, a slide groove 23 and a damping block 24. The rebound column 20 is embedded on the side of the fixed sleeve 19 away from the baffle 16.

[0025] One end of the rebound column 20 is connected to a connecting frame 21, and a side of the connecting frame 21 away from the rebound column 20 is connected to a support spring 22. The inner walls of both sides of the middle of the fixed sleeve 19 are provided with sliding grooves 23. Both ends of the connecting frame 21 are provided with damping blocks 24. The damping blocks 24 are embedded in the sliding grooves 23. The damping blocks 23 are made of rubber. The end of the buffer mechanism 18 away from the baffle 16 is connected to a buffer plate 25. When the unloading platform 3 is tilted, the pipeline will move toward the direction of the buffer plate 25 during unloading. When the pipeline hits the buffer plate 25, the buffer plate 25 drives the rebound column 2 0 moves into the fixed sleeve 19, the rebound column 20 drives the connecting frame 21 to be squeezed in the direction of the supporting spring 22, the supporting spring 22 is compressed and contracts to absorb the impact force of the pipeline against the buffer plate 25, and after contraction, the supporting spring 22 pushes the connecting frame 21 to rebound, and the movement of the connecting frame 21 drives the damping block 24 to move in the slide groove 23, and the friction between the damping block 24 and the slide groove 23 produces a certain damping effect, thereby reducing the impact caused by the rebound of the supporting spring 22, thereby playing a buffering role, thereby reducing the situation where the pipeline slides too fast during unloading and causes impact damage.

[0026] Working principle: When using a discharge device that is convenient for preventing pipes from falling when unloading, the telescopic cylinder 2 can be lifted and lowered to facilitate adjusting the height of the discharge platform 3 so as to facilitate unloading of pipes at different heights. The servo motor 6 can drive the screw 5 to rotate, and the rotation of the screw 5 can drive the moving bar 7 to perform axial translation. The movement of the moving bar 7 drives the bottom end of the top rod 8 to move, so that the top rod 8 is tilted, so that one end of the discharge platform 3 is tilted, so as to facilitate unloading of the pipe. The guardrail 9 plays a protective role to prevent the pipe from falling from the side. The No. 2 servo motor 15 can drive the No. 2 screw 13 to rotate, and the rotation of the No. 2 screw 13 drives the moving block 14 to perform axial translation. The movement of the moving block 14 drives the extension plate 12 to perform translation, so as to realize the telescopic function of the extension plate 12, so that when facing unloading at different inclination angles, the extension plate 12 can be extended to ensure that the unloading work can be carried out, which is convenient for efficient pipe unloading in various complex environments. The baffle 16 plays a blocking role to prevent the pipeline from sliding off the unloading platform 3 quickly and thus damaging or injuring the staff. The electric telescopic rod 17 can push the baffle 16 to rotate along the rotating shaft so as to cancel the blocking of the pipeline and facilitate the unloading of the pipeline. When the unloading platform 3 is tilted, the pipeline will move in the direction of the buffer plate 25 during unloading. When the pipeline hits the buffer plate 25, the buffer plate 25 drives the rebound column 20 to move into the fixed sleeve 19, and the rebound column 20 drives the connecting frame 21 to be squeezed in the direction of the supporting spring 22. The supporting spring 22 is compressed and contracts to absorb the impact force of the pipeline hitting the buffer plate 25. After contraction, the supporting spring 22 pushes the connecting frame 21 to rebound. The movement of the connecting frame 21 drives the damping block 24 to move in the slide groove 23. The friction between the damping block 24 and the slide groove 23 produces a certain damping effect, thereby reducing the impact caused by the rebound of the support spring 22, thereby playing a buffering role, thereby reducing the situation where the pipeline slides too fast during unloading and causes impact damage.
