[0035] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0036] As Figures 1 to 10 shown, a galvanizing device capable of rapid model change includes an inclined transfer frame 1, and further includes a transfer assembly, an internal blowing assembly and a galvanized pipe adjusting assembly. The transfer assembly is arranged on the inclined surface of the transfer frame 1, and is used to support the galvanized pipe body and adjust the support span. The internal blowing assembly is located at the top end of the inclined surface of the transfer frame 1, and is used to clamp and internally blow the end portion of the galvanized pipe body on the transfer assembly. The galvanized pipe adjusting assembly is arranged above the transfer frame 1, and is used to adjust the position of the galvanized pipe body to be internally blown on the transfer assembly, so that the end portion of the galvanized pipe body to be internally blown is in the butt clamping position of the internal blowing assembly.

[0037] The transfer assembly comprises a first moving seat 2 and a second moving seat 3, both of which are rolling supported on the inclined surface of the transfer frame 1, and the side walls of the first moving seat 2 and the second moving seat 3 are fixedly connected with sliding seats 4, which are slidingly connected at the edge of the transfer frame 1, and the bottom of the first moving seat 2 and the second moving seat 3 is fixedly installed with a first air cylinder 5 between the transfer frame 1, and the end of the first moving seat 2 and the second moving seat 3 is fixedly connected with a support plate 6, the top of which is provided with two pairs of V-shaped first support grooves 7, and the support plate 6 on the first moving seat 2 and the second moving seat 3 is provided with a galvanized pipe moving assembly, which is used to transfer a pair of galvanized pipe bodies from one side of the support plate 6 to the first support groove 7 at the fourth position d on the top of the support plate 6, and after the internal blowing is completed, the galvanized pipe body after the internal blowing is transferred to the fifth position e of the first support groove 7, and finally the galvanized pipe body after the internal blowing is moved to the other side of the support plate 6. It should be understood that when the length of the galvanized pipe body changes, in order to better support the galvanized steel pipe body, the support span is adjusted so that the galvanized pipe body is supported at the top end in the internal blowing position of the internal blowing assembly. The method for adjusting the support span is as follows: when the length of the galvanized pipe body increases, the first air cylinder 5 is started to pull the second moving seat 3 through the first air cylinder 5, the second moving seat 3 drives the support plate 6 to move, so that the span between the two support plates 6 increases to adapt to the growing galvanized pipe body, and the length change of the galvanized pipe body is realized.

[0038] When it is necessary to move the support point close to the internal blowing assembly, the first air cylinder 5 can be started to pull the first moving seat 2, and the first moving seat 2 drives the support plate 6 to move close to the internal blowing assembly to support the galvanized pipe body. The bottom of the first moving seat 2 and the second moving seat 3 is fixedly installed with a connecting wheel 8 at four corners, which is rolling lapped on the strip-shaped track on the inclined surface of the transfer frame 1.

[0039] The galvanized pipe moving assembly comprises a mounting frame 9 and a second support shaft 10, the mounting frame 9 is fixedly connected to the side wall of the transfer frame 1, the top end of the mounting frame 9 is rotationally connected with a first support shaft 11, the second support shaft 10 is inserted into the support plate 6, the end of the second support shaft 10 is fixedly connected with a cylindrical block 12, the surface of the cylindrical block 12 is slidingly connected with a sleeve 13, the sleeve 13 is fixedly connected to the surface of the support plate 6, the surfaces of the first support shaft 11 and the second support shaft 10 are fixedly sleeved with a turnover plate 14, the ends of the two turnover plates 14 are rotationally connected with a connecting plate 15, the ends of the two connecting plates 15 are fixedly connected with a transfer claw 16, the transfer claw 16 has three pairs of V-shaped second support grooves 17, the surface of the mounting frame 9 is fixedly installed with a first motor 18, and the output end of the first motor 18 is fixedly connected with the end of the first support shaft 11. It should be understood that the galvanized pipe body after galvanizing is moved to one side of the support plate 6 under the conveying of the external conveying chain, then the first motor 18 is started, the first motor 18 drives the first support shaft 11 to rotate, the first support shaft 11 drives the turnover plate 14 to overturn, under the support of the second support shaft 10, the two connecting plates 15 and the transfer claw 16 of the turnover plate 14 move to form a parallelogram four-bar linkage structure, in the process of movement of the transfer claw 16, one pair of second support grooves 17 at the first position a on the transfer claw 16 supports two galvanized pipe bodies on the external conveying chain, one pair of second support grooves 17 at the second position b supports the galvanized pipe body in the first support groove 7 at the fourth position d on the support plate 6, and the second support groove 17 at the third position c supports the to-be-accepted galvanized pipe body in the first support groove 7 at the fifth position e on the support plate 6;

[0040] When the transfer claw 16 continues to move, the galvanized pipe body supported by the second support groove 17 at the first position a is placed into the first support groove 7 at the fourth position d on the support plate 6 and is ready for cold blowing, the galvanized pipe body supported by the second support groove 17 at the second position b is placed into the first support groove 7 at the fifth position e on the support plate 6 and is ready to be removed, and the galvanized pipe body in the second support groove 17 at the third position c is removed from the support plate 6 and is ready to be accepted and lowered by the next accepting and lowering assembly and then conveyed away by the external conveying assembly. Through the above transfer work, the galvanized pipe bodies are transferred in turn and are subjected to internal blowing treatment in the process of transfer.

[0041] Through the connection and support of the sleeve 13 and the cylindrical block 12, in the process of movement of the first moving seat 2 and the second moving seat 3, the second support shaft 10 avoids limiting the first moving seat 2 or the second moving seat 3.

[0042] The inclined surface of the transfer frame 1 is also fixedly provided with an auxiliary support plate 19, the top of the auxiliary support plate 19 is provided with two pairs of V-shaped third support grooves 20, and the auxiliary support plate 19 is located between the first moving seat 2 and the second moving seat 3. It should be understood that, since there is a span between the two support plates 6, the galvanized pipe body located between the two support plates 6 needs to be further supported, the two pairs of third support grooves 20 on the auxiliary support plate 19 can cooperate with the two pairs of first support grooves 7 on the support plate 6, and the galvanized pipe body to be blown in and the galvanized pipe body to be moved away are assisted and supported, so that the galvanized pipe body is further supported at the position between the two support plates 6, which is beneficial to avoid the situation that the galvanized pipe body is excessively deformed due to the gravity.

[0044] The galvanized pipe adjusting assembly comprises a plurality of rolling support assemblies and a pushing assembly, the plurality of rolling support assemblies are respectively arranged on the surfaces of the two lifting plates 25 and the auxiliary support plate 19, the rolling support assembly comprises two first electric cylinders 24, the first electric cylinders 24 of the plurality of rolling support assemblies are respectively fixedly installed on the surfaces of the two support plates 6 and the auxiliary support plate 19, the telescopic ends of the two first electric cylinders 24 on the same rolling support assembly are fixedly connected with the lifting plate 25, the lifting plate 25 is inserted with two support rods 26, the top of the two support rods 26 is fixedly connected with a frame body 27, the surfaces of the two support rods 26 are both sleeved with a first support spring 28, the two ends of the first support spring 28 are respectively fixedly connected with the frame body 27 and the lifting plate 25, the top end of the frame body 27 is rotatably connected with two pairs of support wheels 29, the same pair of two support wheels 29 supports the galvanized pipe body to be internally blown, the top of the lifting plate 25 is provided with a first pressure sensor 30, the detection end of the first pressure sensor 30 is in contact with the bottom end of the frame body 27, the pushing assembly is arranged on the second moving seat 3, and the pushing assembly is used for pushing the bottom end of the galvanized pipe body to be internally blown, so that the top end of the galvanized pipe body is butted with the internal blowing assembly.

The galvanized pipe body to be internally blown moves close to the pushing assembly under the action of gravity, the two galvanized pipe bodies to be internally blown are pushed to move through the pushing assembly, until the top end of the galvanized pipe body moves to the internal blowing assembly, the position of the galvanized pipe body of different lengths is adjusted, the distance between the galvanized pipe body and the internal blowing assembly is automatically adjusted, the situation that the galvanized pipe body and the internal blowing assembly cannot be normally butted due to the length change of the galvanized pipe body is avoided, and then the internal blowing of the galvanized pipe body is facilitated, and the stable formation of the galvanized layer in the galvanized pipe body is ensured;

[0045] Through the support of the support wheels 29, the galvanized pipe body is rolling supported, so that the surface of the galvanized pipe body is prevented from being scratched with the support of the first support groove 7 in the process of moving the galvanized pipe body, and the harm to the galvanized layer on the surface of the galvanized pipe body is reduced in the process of butting the galvanized pipe body with the internal blowing assembly.
