Description

Technical Field

[0001] This utility model relates to the field of steel product processing technology, specifically to a steel pipe hot-dip galvanizing fixing device. Background Technology

[0002] Hot-dip galvanizing is one of the most effective means of delaying environmental corrosion of steel materials. It involves immersing cleaned and activated steel products in molten zinc, and through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is deposited on the surface of the steel products.

[0003] Traditional galvanizing equipment typically arranges steel pipes longitudinally in a row and places them on a pallet or chain with V-shaped grooves before immersing them in a galvanizing bath. However, the poor fluidity of the zinc bath results in a slow turnover rate of the zinc on the surface of the steel pipe, leading to uneven coating thickness. Utility Model Content

[0004] To solve the above problems, this utility model provides a hot-dip galvanized steel pipe fixing device, comprising:

[0005] A connecting mechanism, a fixing mechanism connected to the connecting mechanism, and a swing mechanism disposed on the connecting mechanism and connected to the fixing mechanism;

[0006] The fixing mechanism is used to fix the pipe to be galvanized, and includes: a bidirectional threaded rod, a bidirectional threaded sleeve connected to the bidirectional threaded rod, a T-shaped frame connected to the bidirectional threaded sleeve, a support arm provided on the T-shaped frame, a fixing clamp provided on the support arm, and an adjusting component adapted to the fixing clamp.

[0007] The fixing clamp and adjusting component are adapted to fix the pipe to be galvanized.

[0008] Preferably, the fixing clamp includes: a first clamping block and a second clamping block adapted to the first clamping block;

[0009] The first clamping block is fixed, and the second clamping block is movable.

[0010] Preferably, the middle of the first clamping block and the second clamping block are recessed, and are used to fix the pipe to be galvanized after abutting against it.

[0011] Preferably, the adjusting member is threadedly connected to the fixed clamp, and one end of the adjusting member abuts against the end of the second clamping block away from the first clamping block to limit the position of the second clamping block.

[0012] Preferably, the swing mechanism includes: an output cylinder, a swing arm connected to the output end of the output cylinder, and a transmission shaft connected to the swing arm.

[0013] Preferably, one end of the swing arm is hinged to the output end of the output cylinder, and the other end is perpendicularly connected to the drive shaft. The drive shaft is rotatably mounted on the connecting frame and is also connected to the connecting arm.

[0014] Preferably, the adjusting element is a locking bolt.

[0015] By adopting the above technical solution, this utility model mainly has the following technical effects:

[0016] By fixing the galvanized pipes in batches using a fixing mechanism, and then using a swinging mechanism to drive the connecting arm to swing, the galvanized pipes in the fixing mechanism are made to swing. This solves the technical problem that the poor fluidity of the zinc liquid leads to a slow renewal rate of the zinc liquid on the steel pipe surface, resulting in uneven coating thickness. This achieves the technical effect of improving the uniformity of the galvanizing process and reducing the coating thickness deviation. Attached Figure Description

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0027] Please see Figures 1-4 This utility model provides a steel pipe hot-dip galvanizing fixing device, including: a connecting mechanism 1, a fixing mechanism 2 connected to the connecting mechanism 1, and a swing mechanism 3 disposed on the connecting mechanism 1 and connected to the fixing mechanism 2.

[0028] In some embodiments, the connecting mechanism 1 includes: a connecting frame 11, a connecting arm 12 connected to the connecting frame 11, and a fixing plate 13 connected to the connecting arm 12. In some embodiments, the connecting frame 11 can be connected to other equipment, thereby connecting the hot-dip galvanized steel pipe fixing device to other equipment. For example, it can be connected to a lifting device, thereby using the lifting device to move the hot-dip galvanized steel pipe fixing device.

[0029] In some embodiments, the fixing mechanism 2 is a part used to fix the pipe to be galvanized, which includes: a bidirectional threaded rod 21, a bidirectional threaded sleeve 22 connected to the bidirectional threaded rod 21, a T-shaped frame 23 connected to the bidirectional threaded sleeve 22, a support arm 24 provided on the T-shaped frame 23, a fixing clamp 25 provided on the support arm 24, and an adjusting member 26 adapted to the fixing clamp 25. In some embodiments, the bidirectional threaded rod 21 is a straight rod with both right-hand and left-hand threads, usually of equal length or symmetrically arranged. When the entire rod rotates, the two bidirectional threaded sleeves 22 respectively fitted on the two threads will move synchronously in opposite directions or in a straight line, thereby turning "one rotation" into "two straight movements in opposite directions".

[0030] Furthermore, the top of the T-shaped frame 23 is connected to the bidirectional threaded sleeve 22, thereby adjusting the distance between the two sets of T-shaped frames 23 by moving the bidirectional threaded sleeve 22 closer to or further away from each other on the bidirectional threaded rod 21 to accommodate various specifications of pipes to be galvanized.

[0031] In some embodiments, the fixing clamp 25 is adapted to the adjusting member 26 for fixing the pipe to be galvanized. The fixing clamp 25 is a square hollow structure, including: a first clamping block 251 and a second clamping block 252 adapted to the first clamping block 251. The first clamping block 251 is fixedly disposed in the fixing clamp 25 and cannot be moved. The second clamping block 252 is movably disposed in the fixing clamp 25 and can move closer to or further away from the first clamping block 251. The middle parts of the first clamping block 251 and the second clamping block 252 are concave and are used to fix the pipe to be galvanized after abutting against it.

[0032] Furthermore, the adjusting member 26 is threadedly connected to the fixed clamp 25. One end of the adjusting member 26 abuts against the end of the second clamping block 252 away from the first clamping block 251 to limit the second clamping block 252. After the adjusting member 26 is threadedly connected to the fixed clamp 25, the operator can rotate the adjusting member 26 to limit the second clamping block 252 after the adjusting member 26 abuts against it. The first clamping block 251 and the second clamping block 252 abut against the pipe to be galvanized to fix the pipe to be galvanized. Alternatively, the adjusting member 26 can be rotated in the opposite direction to move the adjusting member 26 away from the second clamping block 252, increasing the distance between the second clamping block 252 and the first clamping block 251, thereby unlocking the pipe to be galvanized.

[0033] In some embodiments, the adjusting member 26 may be a locking bolt.

[0034] In some more preferred embodiments, the swing mechanism 3 includes: an output cylinder 31, a swing arm 32 connected to the output end of the output cylinder 31, and a transmission shaft 33 connected to the swing arm 32. One end of the swing arm 32 is hinged to the output end of the output cylinder 31, and the other end is perpendicularly connected to the transmission shaft 33. The transmission shaft 33 is rotatably mounted on the connecting frame 11 and is also connected to the connecting arm 12. Thus, by utilizing the operation of the output cylinder 31, the transmission shaft 33 is rotated via the swing arm 32, which in turn drives the connecting arm 12 connected to the transmission shaft 33 to swing. The swinging of the connecting arm 12 causes the galvanized pipe in the fixing mechanism 2 to swing, thereby improving the uniformity of the galvanizing process and reducing the coating thickness deviation.

[0035] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
