Hanging tool for hot galvanizing process

Abstract

According to the hanging tool for the hot galvanizing process, a tool is hung through a hook, after the tool is hung, due to the gravity effect, two T-shaped blocks are close to each other to extrude a spring, and in the moving process of the T-shaped blocks, a driving mechanism arranged above the T-shaped blocks through an L-shaped connecting plate can drive a jacking and stabilizing structure to jack the tool, so that the tool is prevented from being damaged. The maximum descending height of the tool due to the gravity is limited by the stable lifting part, after the tool reaches the limiting position, the tool can be tightly jacked through the jacking stabilizing structure, and therefore the stability of the moving process of the tool is maintained.

Description

Technical Field

[0001] The utility model relates to the field of hot-dip galvanizing hangers, in particular to a hanger used in a hot-dip galvanizing process. Background Art

[0002] Hot-dip galvanizing is a process for anti-corrosion treatment of steel materials. After the surface is cleaned and activated, it is immersed in molten zinc liquid. Through the reaction and diffusion between iron and zinc, a zinc alloy coating with good adhesion is plated on the surface of the steel product.

[0003] During the hot-dip galvanizing process, the workpiece is usually loaded into a tooling, and the tooling with the workpiece is sent into the galvanizing pool through a hanger. The existing hanger has a simple structure and is prone to shaking or even falling off the hook during the movement of the tooling on the hook, which is not safe enough. Utility Model Content

When the tooling with the workpiece is hung on the hook, under the action of its gravity, the T-blocks on both sides will move toward the middle in the T-slot at the same time, squeezing the springs against each other, and the hook position moves down. The hook mounting block is installed through a stable lifting part arranged under the fixed plate. The setting of the stable lifting part allows the hook mounting block to move down stably when moving down. An L-shaped connecting plate is fixed on the upper surface of the T-block extending out of the T-slot, and the driving mechanism and the tightening stabilizing structure are installed through the L-shaped connecting plate. During the movement of the T-block, the driving mechanism drives the tightening stabilizing structure to operate, tightens the work hanging below, maintains its stability, and avoids shaking violently and falling off easily during movement.

[0005] As a preferred technical solution of the utility model, mounting shafts are fixed on the upper and lower parts of the T-slot, and a roller is fixed on the mounting shaft. The surface of the roller is smooth and contacts the surface of the T-block. Through the arrangement of the mounting shaft and the roller, the T-block can slide more smoothly in the T-slot, reducing friction during movement.

[0006] As a preferred technical solution of the utility model, the stable lifting part includes a vertical stable groove and a vertical stable axis. A vertical plate body is integrally formed at the center of the lower surface of the fixed plate. A vertical stable groove is opened on the front side of the plate body. The vertical stable axis is fixed in the vertical stable groove. The hook mounting block is movably mounted on the vertical stable axis. When the hook is driven downward by the gravity of the object hung on it, the hook mounting block can move stably along the vertical stable axis.

[0007] As a preferred technical solution of the utility model, the driving mechanism includes a top mounting plate, a gear, a top T-plate and a tooth groove portion. The top mounting plate is fixed to the outer end of the L-shaped connecting plate, and a shaft body is rotatably mounted on the top mounting plate. A gear is fixed to the upper end of the shaft body. The top T-plate is fixed to the top of the fixed plate. The front side of the horizontal part of the top T-plate is the tooth groove portion, and the tooth groove portion is meshed with the gear. During the movement of the T-block, the gear and the tooth groove portion move relative to each other, and the gear rotates under the meshing action of the two.

[0008] As an optimal technical solution of the utility model, the tightening and stabilizing structure includes a guide shaft, a rotating stud, an outer L-shaped mounting frame and a V-shaped tightening frame. The guide shaft is fixedly installed on the lower part of the top mounting plate, and the rotating stud is rotatably installed. The rotating stud is coaxially installed with the gear, that is, the gear can drive the rotating stud to rotate when it rotates. The horizontal parts of the outer L-shaped mounting frame are respectively movably mounted on the guide shaft and are installed in cooperation with the rotating stud. When the rotating stud rotates, the outer L-shaped mounting frame equipped with it will move along the guide shaft. The lower end of the vertical part of the outer L-shaped mounting frame is fixed with a V-shaped tightening frame, and the V-shaped tightening frame is made of rigid material.

[0009] The beneficial effects of the utility model are as follows: the tooling is hung by a hook, and after the tooling is hung, due to the effect of gravity, the two T-blocks approach each other to squeeze the spring, and during the movement of the T-block, the driving mechanism arranged on the upper side through the L-shaped connecting plate can drive the tightening stabilizing structure to tighten the tooling, and the maximum height of the tooling itself that drops due to gravity is limited by the stable lifting part, and when it reaches the limited position, the setting of the tightening stabilizing structure can enable it to tighten the tooling, thereby maintaining the stability of its movement process.
