Description

Technical Field

[0001] This utility model relates to the technical field of hot-dip galvanizing tanks for power railways, and in particular to a pickling tank for hot-dip galvanizing of power railway accessories. Background Technology

[0002] Hot-dip galvanizing is a process in which molten metal reacts with an iron substrate to create an alloy layer, thereby bonding the substrate and the coating. The process involves first pickling the steel parts to remove iron oxide from their surface. After pickling, the parts are cleaned in an aqueous solution of ammonium chloride or zinc chloride, or a mixture of both, before being immersed in a hot-dip galvanizing bath.

[0003] The outer wall of the pickling tank is fixedly equipped with a drain pipe. During use, the drain pipe needs to be inspected and replaced regularly. In the existing technology, the drain pipe is connected to the pickling tank through internal and external thread matching, which makes the installation process very cumbersome. There is an urgent need for a pickling tank for hot-dip galvanizing of power iron accessories to solve the above problems. Therefore, we propose a pickling tank for hot-dip galvanizing of power iron accessories. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art by providing an acid pickling tank for hot-dip galvanizing of power iron accessories.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a pickling tank for hot-dip galvanizing of power iron accessories, comprising a pickling tank shell, a drain pipe fixedly connected to the output end of the pickling tank shell, a constraint groove opened at the end of the drain pipe away from the pickling tank shell, a guide pipe movably installed inside the constraint groove, mounting blocks symmetrically fixedly connected to the sides of the guide pipe, and elastic blocks movably installed on the mounting blocks. The elastic blocks are arc-shaped. A constraint block is fixedly connected to the side of the drain pipe corresponding to the position of the mounting block. A hook is fixedly connected to one end of the elastic block corresponding to the constraint block, and the hook engages inside the constraint block. A constraint device for squeezing the elastic block is provided on the side of the drain pipe corresponding to the center position of the elastic block. The constraint device includes a threaded column, a compression threaded sleeve threadedly connected to the outer side of the threaded column, grooves equidistantly opened on the outer side of the compression threaded sleeve, and a protrusion fixedly connected to the side of the compression threaded sleeve corresponding to the elastic block.

[0006] As a further improvement of this utility model, an installation cavity is provided on the inner side of the constraint groove corresponding to one end of the guide tube, and a rubber ring is snapped into the inside of the installation cavity.

[0007] As a further improvement of this utility model, two sliding grooves are symmetrically opened on the inner side of the discharge pipe. The sliding grooves are rectangular grooves, and a slider is fixedly connected to the side of the guide pipe corresponding to the position of the sliding groove. The slider is movably installed inside the sliding groove.

[0008] Beneficial effects

[0009] This utility model provides an pickling tank for hot-dip galvanizing of power railway accessories. It has the following beneficial effects:

[0010] (1) The pickling tank for hot-dip galvanizing of the electric iron accessory is used to insert the guide tube into the inside of the constraint tank. The elastic block is rotated around the mounting block as the axis so that the hook on the elastic block is locked inside the constraint block. Then, the constraint device is used to squeeze the center position of the side of the elastic block so that the elastic block is in a taut state. The elastic block has a force that brings the constraint block and the mounting block closer together to lock the guide tube, thus completing the installation of the drain pipe and improving the replacement efficiency after maintenance.

[0019] Example 1: A pickling tank for hot-dip galvanizing of power railway accessories, such as... Figures 1-3 As shown, the system includes a pickling tank housing 14. A drain pipe 1 is fixedly connected to the output end of the pickling tank housing 14. A constraint groove 2 is formed at the end of the drain pipe 1 away from the pickling tank housing 14. A guide pipe 3 is movably installed inside the constraint groove 2. Mounting blocks 4 are symmetrically fixedly connected to the sides of the guide pipe 3. Elastic blocks 5, which are arc-shaped, are movably installed on the mounting blocks 4. A constraint block 6 is fixedly connected to the side of the drain pipe 1 at a position corresponding to the mounting block 4. A hook 7 is fixedly connected to one end of the elastic block 5 corresponding to the constraint block 6, and the hook 7 engages inside the constraint block 6. A constraint device for squeezing the elastic block 5 is provided on the side of the drain pipe 1 at the center position corresponding to the center of the elastic block 5. The guide pipe 3 is inserted into the constraint groove. Inside 2, the elastic block 5 rotates around the mounting block 4 as the axis, causing the hook 7 on the elastic block 5 to engage inside the constraint block 6. Then, the constraint device compresses the center position of the side of the elastic block 5, putting the elastic block 5 in a taut state. The elastic block 5 exerts a force on the constraint block 6 and the mounting block 4 to lock the guide tube 3, completing the installation of the drain pipe. This facilitates the inspection and replacement of the drain pipe, improving the efficiency of inspection and replacement. The constraint device includes a threaded post 10, with a compression threaded sleeve 11 threadedly connected to the outer side of the threaded post 10. The compression threaded sleeve 11 has grooves 12 equidistantly spaced around its outer circumference. A protrusion 13 is fixedly connected to one side of the compression threaded sleeve 11 corresponding to the elastic block 5.

A slider 16 is fixedly connected to the side of the guide pipe 3 at the position corresponding to the groove 15. The slider 16 is movably installed inside the groove 15 to realize the positioning function and make the guide pipe 3 more stable after installation.
