Description

Technical Field

[0001] The utility model relates to a processing device for ductile iron pipes, in particular to a continuous conveying mechanism for cast pipes. Background Art

[0002] At present, the production line conveys ductile iron pipes by placing them on an inclined conveying track and applying an initial driving force to them, so that they can automatically roll forward along the conveying track to the next stop under the driving action. At the same time, in order to achieve the alternation between continuous conveying and step-by-step conveying of ductile iron pipes, a pipe turning rack is installed on the conveying track. The pipe turning rack intercepts the ductile iron pipes rolling forward in a low position. After being lifted, the pipe turning rack conveys a single ductile iron pipe and intercepts the ductile iron pipes behind it at the same time, thereby achieving the step-by-step conveying effect of the ductile iron pipes.

[0003] However, the defect of this conveying mechanism is that after the pipe turning rack is lifted, the ductile iron pipe at the rear will continue to roll forward under the driving action of the conveying track until it contacts the pipe turning rack, causing the pipe turning rack to scratch the surface of the ductile iron pipe at the rear during the lifting process, and easily causing mutual jamming between the ductile iron pipe and the pipe turning rack, that is, the ductile iron pipe will provide resistance to the pipe turning rack in the rotation direction after contacting the pipe turning rack, causing the pipe turning rack to be unable to reset smoothly after completing the pipe turning action.

[0004] Therefore, the existing conveying mechanism for ductile iron pipes has the problems of poor pipe conveying stability and easy jamming of the cast pipes. Utility Model Content

[0010] In the aforementioned continuous conveying mechanism for cast pipes, the top of the pipe turning frame is provided with a V-shaped pipe blocking surface and a pipe turning surface. The pipe blocking surface is located at the rear end of the pipe stopping groove and is used to intercept the cast pipe.

[0013] Compared with the prior art, the utility model has the following characteristics:

[0015] (2) By setting the slope of the second conveying track, the cast pipe can automatically roll into the first conveying track after entering the second conveying track, thereby ensuring the continuous conveying effect of the rear cast pipe;

[0016] (3) Through the structural coordination of the third conveying track and the driving part, an initial driving force can be provided to the casting pipe placed on the third conveying track, so that the casting pipe continues to be conveyed forward along the third conveying track under the action of the driving force, thereby realizing the re-conversion of the casting pipe between step-by-step conveying and continuous conveying;

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] Example 1. A continuous conveying mechanism for a cast pipe, comprising: Figure 1 As shown, it comprises a first conveying track 1, a V-shaped pipe stopping groove 2 is provided in the middle of the first conveying track 1, a pipe turning frame 3 rotatably connected to the first conveying track 1 is provided on one side of the pipe stopping groove 2, the outside of the pipe turning frame 3 is connected to the first conveying track 1 via a first telescopic rod 4, and a pipe transporting frame 5 rotatably connected to the first conveying track 1 is provided on the other side of the pipe stopping groove 2, and the outside of the pipe transporting frame 5 is connected to a second telescopic rod 6;

[0024] The first conveying track 1 is used for placing and parking the casting pipe;

[0025] The pipe turning rack 3 is used to convey the cast pipe in the pipe stopping groove 2 forward after lifting;

[0026] The pipe transport rack 5 is used to transport the cast pipe on the first conveying track 1 after lifting, so that the cast pipe rolls toward the pipe stopping groove 2 when the pipe turning rack 3 is in a low position.

[0027] The top of the pipe turning frame 3 is provided with a V-shaped pipe blocking surface 301 and a pipe turning surface 302. The pipe blocking surface 301 is located at the rear end of the pipe stopping groove 2 and is used to intercept the cast pipe. The pipe turning surface 302 is located below the pipe stopping groove 2 and is used to transport the cast pipe after lifting.

[0028] The first conveying track 1 is connected to the second conveying track 7 at the front end along the rolling direction of the cast pipe. The top of the second conveying track 7 forms a first conveying surface for conveying the cast pipe. The slope of the first conveying surface is greater than the slope of the top surface of the first conveying track 1. The slope of the pipe transport rack 5 after lifting is greater than the slope of the top surface of the first conveying track 1.

[0029] The top surface slope of the first conveying track 1 is 1-2°, that is, the cast pipe in a rolling state can continue to roll forward after entering the first conveying track 1 until it contacts the cast pipe in front and stops. After stopping, the cast pipe cannot be restarted due to the slope of the first conveying track 1.

[0030] When this embodiment is in use, the rear cast pipe rolls along the second conveying track 7 to the first conveying track 1 under the driving action, and is intercepted by the front cast pipe and is in a stagnant state. At the same time, the pipe turning rack 3 transports the cast pipe in the pipe stopping groove 2 by regular lifting, so that the cast pipe enters the next station in a step-by-step manner at a specified conveying rhythm. When the pipe turning rack 3 turns the pipe, the pipe transport rack 5 is in a low position and keeps the cast pipe on the first conveying track 1 in a stagnant state, thereby preventing the cast pipe from continuing to roll forward and contacting the pipe turning rack 3 after losing the interception. When the pipe turning rack 3 is reset, the pipe transport rack 5 rises to transport the cast pipe on the first conveying track 1, so that the cast pipe can roll along the pipe transport rack 5 toward the pipe stopping groove 2, thereby realizing the function of feeding the cast pipe. During the rolling process of the cast pipe, it can be intercepted by the pipe blocking surface 301, so that the cast pipe can be stably parked in the pipe stopping groove 2 under the interception effect, which is convenient for the next pipe feeding of the pipe turning rack 3.

[0031] Example 2. A continuous conveying mechanism for a cast pipe, comprising: Figure 1 As shown, it comprises a first conveying track 1, a V-shaped pipe stopping groove 2 is provided in the middle of the first conveying track 1, a pipe turning frame 3 rotatably connected to the first conveying track 1 is provided on one side of the pipe stopping groove 2, the outside of the pipe turning frame 3 is connected to the first conveying track 1 via a first telescopic rod 4, and a pipe transporting frame 5 rotatably connected to the first conveying track 1 is provided on the other side of the pipe stopping groove 2, and the outside of the pipe transporting frame 5 is connected to a second telescopic rod 6;

[0032] The first conveying track 1 is used for placing and parking the casting pipe;

[0033] The pipe turning rack 3 is used to convey the cast pipe in the pipe stopping groove 2 forward after lifting;

[0034] The pipe transport rack 5 is used to transport the cast pipe on the first conveying track 1 after lifting, so that the cast pipe rolls toward the pipe stopping groove 2 when the pipe turning rack 3 is in a low position.

[0035] The top of the pipe turning frame 3 is provided with a V-shaped pipe blocking surface 301 and a pipe turning surface 302. The pipe blocking surface 301 is located at the rear end of the pipe stopping groove 2 and is used to intercept the cast pipe. The pipe turning surface 302 is located below the pipe stopping groove 2 and is used to transport the cast pipe after lifting.

[0036] The first conveying track 1 is connected to a second conveying track 7 at the front end along the rolling direction of the cast pipe. The top of the second conveying track 7 forms a first conveying surface for conveying the cast pipe. The slope of the first conveying surface is greater than the slope of the top surface of the first conveying track 1.

[0037] The first conveying track 1 is provided with a third conveying track 8 at one end away from the second conveying track 7. The third conveying track 8 and the first conveying track 1 are spaced apart. A stepping conveying beam is installed between the third conveying track 8 and the first conveying track 1. The top of the third conveying track 8 forms a second conveying surface for conveying cast pipes. The end of the third conveying track 8 forms a driving part 9. The top of the driving part 9 forms an inclined third conveying surface. The slope of the third conveying surface is greater than that of the second conveying surface.

[0038] Compared with Example 1, this embodiment cooperates with the third conveying track 8 and the driving unit 9 arranged in front of the first conveying track 1, so that after the cast pipe leaves the first conveying track 1 and completes the corresponding processing steps, the cast pipe can be placed on the third conveying track 8 in sequence by the step-by-step conveying beam, and the driving unit 9 applies an initial driving force to the cast pipe entering the third conveying track 8, so that the cast pipe can automatically roll forward under the driving action, thereby realizing the conversion from step-by-step conveying to continuous conveying, and improving the conveying effect of the cast pipe.
