[0001] The invention relates to the technical field of pipeline buffering, and in particular to a curved buffering device for a ductile iron pipe. Background Art

[0002] Ductile iron pipe is a kind of cast iron pipe, which has the essence of iron and the performance of steel. After annealing, the metallographic structure of ductile iron pipe is ferrite plus a small amount of pearlite, with good mechanical properties, excellent corrosion resistance, good ductility, good sealing performance, and easy installation. It is mainly used for water supply, gas transmission, oil transmission, etc. in municipal and industrial and mining enterprises.

[0003] In the production process, cast pipes are transported by axial conveying devices, such as conveying rollers and conveying chains. Multiple cast pipes are placed on the conveying chain one by one, and the conveying is completed by the transmission of the conveying chain. When the number of cast pipes in the next process is large, the conveying speed of the cast pipes on the conveying chain is reduced, or the conveying can be suspended. Then the cast pipes output from the previous process will accumulate, affecting the output quantity and the entire cast pipe production progress. Since there is no caching device for cast pipes on the conveying chain, the cast pipes cannot be continuously transported at a uniform speed through the conveying chain, affecting the production progress of cast pipes. At present, the motor-driven track is used as a cache track, which consumes electricity and can only be set up in a single layer, occupying a large area and caching few cast pipes.

The storage mechanism can be adjusted in a horizontal plane and is used to store cast pipes of different lengths. The storage mechanism adjusts the storage direction of the cast pipes with the help of the rotating mechanism; the lifting mechanism is arranged at the upper end of the rotating mechanism, and can be raised and lowered and rotated circumferentially, and is used to lift the cast pipe from the cast pipe transportation device to the storage mechanism. The lifting mechanism can also lift the cast pipe to the cast pipe transportation device in reverse.

DETAILED DESCRIPTION

[0030] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1-5 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0031] like Figure 1-5 As shown:

[0032] A ductile iron pipe curved cache device comprises a track support column 1; a curved cache track 2, wherein the curved cache track 2 is arranged on the track support column 1, and the track support column 1 clamps and fixes the curved cache track 2, and a ductile iron pipe is placed in the curved cache track 2; a shift block 9, wherein the shift block 9 is arranged on the curved cache track 2, and an axial hole 11 is provided on the shift block 9, and the shift block is connected to the curved cache track 2 by means of a rotating shaft in the axial hole 11; an oil cylinder 3, wherein the oil cylinder 3 is fixedly connected to a support frame 5, and the support frame 5 is fixed on the track support column 1, and the telescopic end of the oil cylinder 3 is a telescopic rod 4, and the other end of the telescopic rod 4 is connected to the shift block 9, and the oil cylinder 3 can drive the shift block 9 to swing around the axial hole 11.

[0033] In this embodiment, the track support column 1 is placed on the site, and the number of columns is several, which is used to support the curved cache track 2. The curved cache track 2 is designed as an S-shaped curve, which is conducive to temporarily storing a certain number of ductile iron pipes. The curved cache track 2 is designed as a double-layer design, and the middle is a passage for the ductile iron pipes to pass. In order to relieve a certain downward pressure, a blocking block 9 is set on the curved cache track 2. The blocking blocks 9 are set in 3-4 groups, which can achieve the segmented reduction of the rolling speed of the cast pipes on the entire curved cache track 2, and also avoid the rolling force generated by the gravity of all cast pipes from being concentrated at the exit. The swing of the blocking blocks 9 is controlled by the oil cylinder 3, and the oil cylinder 3 is connected to the support frame 5, and the support frame 5 is fixed on the track support column 1. The curved cache track 2 set as a three-dimensional three-layer can store the most cast pipes in a small area; the track is set to be -2° with the horizontal plane, and is a slope. The cast pipes use their own gravity to automatically provide rolling power on the track. The surface of the curved cache track 2 is a rubber 10, which is elastic.

[0034] A mounting hole 20 is provided on the curved cache rail 2, and the mounting hole 20 passes through the curved cache rail 2, and the mounting hole 20 is set in the middle position of the curved cache rail 2. A horizontally set axis is provided in the mounting hole 20, and the axis is perpendicular to the extension direction of the curved cache rail 2. The axis passes through the axis hole 11 and is used for the installation of the shift block 9, and the shift block 9 can rotate around the axis.

[0035] In order to facilitate the installation of the shift block 9, a mounting hole 20 is set on the curved buffer track 2. The mounting hole 20 is a through hole. A horizontally placed shaft is set in the mounting hole 20. The shaft is connected to the shift block 9, and the shift block 9 rotates around the shaft.

[0036] The shift block 9 is provided with a pin shaft 12, which is arranged at one end of the shift block 9 and at the notch position. The pin shaft 12 is connected to the telescopic rod 4, and the axial hole 11 between the telescopic rod 4 and the pin shaft 12 is connected. The telescopic rod 4 can rotate around the pin shaft 12, and the shift block 9 rotates under the push of the telescopic rod 4.

[0037] A pin shaft 12 is provided on the shift block 9 for connecting with the telescopic rod 4. Driven by the telescopic rod 4, the shift block 9 can be swung to fix or release the ductile iron pipe.

[0038] The other end of the oil cylinder 3 is connected to an oil cylinder 3 seat. The oil cylinder 3 and the oil cylinder 3 seat are connected via an axial hole 11 , and the oil cylinder 3 seat is fixed to the support frame 5 via bolts.

[0039] The oil cylinder 3 is connected to the oil cylinder 3 seat, and the oil cylinder 3 and the oil cylinder 3 seat are connected by an axis. This design does not affect the swing range of the oil cylinder 3 when the oil cylinder 3 is in action; 3-4 oil cylinders 3 and shift blocks 9 are arranged on the curved track to prevent the cast pipe from being bumped and damaged when rolling on the cache track.

[0040] The shift block 9 is arranged at the turning point of the curved cache track 2 and at the cache exit position.

[0041] In order to relieve the gravity effect of the ductile iron pipe as a whole, the shifting blocks 9 are divided into several groups and arranged at the turning points and the cache outlets.

[0042] The cross-section of the protrusion 13 is a triangular structure, and the top angle is an arc shape. The protrusion 13 is provided with a plurality of notches arranged at intervals, and a shaft passes through the notch. The shaft is installed at the position of the protrusion 13 through a bearing 15. The shaft is parallel to the axis of the shaft hole 11. A roller 14 is provided on the shaft, and the roller 14 corresponds to the notch position. The roller 14 is fixedly connected to the shaft, and a ratchet 16 is provided at the end of the shaft. The ratchet 16 is arranged at the outer position of the protrusion 13. A motor 19 is also provided on the outer surface of the protrusion 13, and a baffle rod 17 is connected to the output end of the motor 19. The baffle rod 17 is used to fix the rotation of the ratchet 16, and the baffle rod 17 can realize forward and reverse rotation under the drive of the motor 19.

[0043] This design is used to alleviate the friction between the ductile iron pipe and the outer surface of the ductile iron pipe, which is beneficial to protecting the outer surface of the ductile iron pipe. Although the protrusion 13 structure can be used to alleviate the rolling speed of the ductile iron pipe, there is a sliding mode between the protrusion 13 and the ductile iron pipe for a period of time before the release of the shift block 9, which not only wears the ductile iron pipe, but also causes certain damage to the protrusion 13 on the shift block 9, reducing the service life. Based on the principle of caching the ductile iron pipe without reducing the service life of the ductile iron pipe, a plurality of notch positions are set at the protrusion 13 position, and then A roller 14 is provided at the position, and the roller 14 corresponds to the notch position one by one, and the shaft passing through the roller 14 is in rolling connection with the protrusion 13, and the roller 14 is fixedly connected with the shaft, that is, the shaft can drive the roller 14 to rotate, and can also control the roller 14 not to rotate. A bearing 15 is sleeved on the shaft and then connected to the protrusion 13. In addition, a ratchet 16 is provided at the end of the shaft, and the ratchet 16 is controlled by a baffle 17. The baffle 17 can swing left and right under the action of the motor 19, and swing toward the direction of the ratchet 16, which can control the ratchet 16 not to rotate. After disengagement, the roller 14 can rotate along the line of action of the external force.

[0044] Positioning rods 18 are provided on both sides of the blocking rod 17 . The positioning rods 18 are fixed on the side surfaces of the blocking block 9 to limit the movable area of ​​the blocking rod 17 .

[0045] The positioning rod 18 is used to limit the swing of the blocking rod 17 .

[0046] The teeth of the ratchet 16 are inclined arc-shaped structures, and the teeth correspond to the end positions of the blocking rod 17 . When the blocking rod 17 swings to the position of the ratchet 16 , it is used to fix the ratchet 16 .

[0047] The ratchet 16 has an arc-shaped gear tooth structure with four gear teeth, and the gear corresponds to the position of the blocking rod 17 after swinging, so that the ratchet 16 can be fixed by meshing.

[0048] The track support column 1 is provided with a counter 8, and the counter 8 adopts a laser structure.

[0049] A counter 8 is provided on the track support column 1 , which can record the amount of ductile iron passing through the curved buffer track 2 .

[0050] Working method (or working principle) of the present invention:

[0051] When this technology is working, the ductile iron pipe buffer transition device used in the cast pipe production line can temporarily store a part of the cast pipe. If a fault occurs in an individual processing station of the cast pipe production line, the cast pipe in front of the faulty station needs to be placed in the buffer area. The buffer area should not only hold as many cast pipes as possible in a smaller area, but also be easy to place and take out. The curved buffer device in this design can meet such conditions. The device is set as a three-dimensional three-layer curved buffer track 2, which can store the most cast pipes in a smaller area; the track is set to -2° with the horizontal plane, forming a slope, and the cast pipe uses its own gravity to automatically provide rolling forward power on the track; 3-4 groups of oil cylinders 3 and baffle blocks 9 are set, which can realize the segmented reduction of the rolling speed of the cast pipe on the entire track, and also avoid the rolling force generated by the gravity of all cast pipes from being concentrated at the outlet; elastic rubber 10 is set on the surface of the baffle block 9 and the surface of the cache track, and 3-4 oil cylinders 3 and baffle blocks 9 are set on the curved track to avoid collision and damage when the cast pipe rolls on the cache track.

[0052] In the present invention, unless otherwise clearly stipulated and limited, for example, it can be a fixed connection, a detachable connection, or an integrated one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, for ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0053] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
