Description

Technical Field

[0001] This application relates to the technical field of angle steel galvanizing process, and in particular to an angle steel hot-dip galvanizing system and method. Background Technology

[0002] Galvanized angle steel is divided into hot-dip galvanized angle steel and cold-dip galvanized angle steel. Hot-dip galvanized angle steel is also called hot-dip zinc angle steel. It involves immersing rust-removed angle steel in molten zinc at around 500℃, causing a zinc layer to adhere to the surface, thus providing corrosion protection. It is suitable for various highly corrosive environments such as strong acids and alkalis. High-strength hot-dip galvanized steel sheets for structural use are high-value-added products in the metallurgical industry. Due to their high yield strength and tensile strength, strong corrosion resistance, excellent surface quality, good deep-processing performance, and economic applicability, they are widely used in construction, light industry, automobiles, agriculture, and animal husbandry. In the construction industry, they are used for light steel keels, building floor panels, corrugated sheets, and roller shutters in various industrial and civil buildings.

[0003] In the galvanizing process of angle steel, angle steel is usually hung on a lifting device, and then several angle steels are immersed in molten zinc using the lifting device to achieve galvanizing. However, during the process of hanging the angle steel, due to the long length of the angle steel and the tendency of the lifting device to sway, it is not easy to hang the angle steel, resulting in low hanging efficiency. Summary of the Invention

[0004] To improve the low efficiency of hanging angle steel, this application provides a hot-dip galvanizing system and method for angle steel.

[0005] The hot-dip galvanizing system for angle steel provided in this application adopts the following technical solution:

[0006] A hot-dip galvanizing system and method for angle steel includes a galvanizing tank, a transfer frame, a lifting device, and a fixing base. The fixing base includes three fixing plates: a fixing plate one fixed to the ground and two fixing plates two fixed to the ends of the fixing plate one. The fixing plate one and the fixing plate two are perpendicular to each other. The lifting device includes two horizontally arranged moving rods. A hanging component is installed on the bottom surface of the moving rods. The hanging component includes several spaced-apart diamond-shaped frames. A connecting rod is fixed between two adjacent diamond-shaped frames. Several connecting blocks are fixed on the side of the hanging component near the fixing plate. The connecting blocks can be snapped and fixed to the fixing plate. Two placement plates are installed on the transfer frame. The placement plates are arranged parallel to the moving rods. Several placement slots for placing angle steel are opened on the top surface of the placement plates. The transfer frame is provided with a lifting component for controlling the vertical movement of the placement plates and a pushing component for pushing the angle steel toward the direction of the lifting device.

[0007] By adopting the above technical solution, the connecting block and the fixing plate are snapped together, so that the hanging part is not easy to shake. Then, the lifting component is used to move upward so that the angle steel is aligned with the diamond frame. Then, the pushing component is used to push the angle steel towards the diamond frame so that the angle steel is inserted into the diamond frame and is not easy to shake, resulting in high hanging efficiency.

[0008] Preferably, the fixing plate has a connecting groove for inserting the connecting block on its side near the connecting block, and a snap-fit ​​groove is provided on the inner wall of the connecting groove. The fixing plate slides along its own length direction through the snap-fit ​​groove to install the snap-fit ​​block, and the side of the connecting block has a positioning groove for inserting the snap-fit ​​block.

[0009] By adopting the above technical solution, the connecting block is inserted into the connecting groove, and then the snap-fit ​​block is inserted into the positioning groove, so that the connecting block is snap-fitted and fixed with the fixing plate, thereby keeping the hanging piece relatively fixed with the three fixing plates, and the lifting device is not easy to shake, so that the angle steel can be hung in the diamond frame.

[0010] Preferably, a snap-fit ​​spring is fixed to the side of the snap-fit ​​block away from the connecting block, and the end of the snap-fit ​​spring away from the snap-fit ​​block is fixedly connected to the inner wall of the snap-fit ​​groove. A snap-fit ​​inclined surface is provided on the side of the snap-fit ​​block near the connecting block, and the snap-fit ​​inclined surface is located on the side of the snap-fit ​​block near the moving rod.

[0011] By adopting the above technical solution, the connecting block is inserted into the connecting groove, the connecting block abuts against the snap-fit ​​inclined surface and pushes the snap-fit ​​block into the snap-fit ​​groove. When the connecting block is fully inserted into the connecting groove, the snap-fit ​​block is inserted into the positioning groove under the elastic force of the snap-fit ​​spring, thereby realizing the snap-fit ​​fixation of the connecting block and the fixing plate, and the fixing efficiency is high.

[0012] Preferably, the side of the fixing plate furthest from the fixing plate has a pressing groove communicating with the snap-fit ​​groove. A pressing block is slidably mounted on the fixing plate along its width direction through the pressing groove. A positioning groove for the snap-fit ​​block to pass through is provided on the side of the snap-fit ​​block. A positioning inclined surface is provided on the side of the positioning groove furthest from the connecting block. A pressing inclined surface for abutting against the positioning inclined surface is provided on the side of the pressing block near the snap-fit ​​block. A reset block is fixed on the side of the pressing block. A reset groove is provided on the inner wall of the pressing groove. The reset block slides and engages with the fixing plate along the width direction of the fixing plate through the reset groove. A reset spring is fixed on the side of the reset block furthest from the snap-fit ​​block. One end of the reset spring furthest from the reset block is fixedly connected to the inner wall of the reset groove.

[0013] By adopting the above technical solution, after the angle steel is threaded into the diamond frame one by one, the pressing block is pushed, and the pressing inclined surface abuts against the positioning inclined surface. The pressing block pushes the locking block to move away from the connecting block, thereby causing the locking block to disengage from the positioning groove and releasing the locking block from the connecting block, so that the connecting block can disengage from the connecting groove. When the pressing block is released, the pressing block moves away from the locking block under the elastic force of the return spring, and the pressing block resets, thus facilitating the reset of the locking block.

[0014] Preferably, the connecting groove has an abutment groove on the inner wall away from the rhombus frame, and the fixing plate slides along its own thickness direction through the abutment groove to install an abutment block. An abutment spring is fixed to the side of the abutment block away from the rhombus frame, and the end of the abutment spring away from the abutment block is fixedly connected to the inner wall of the abutment groove.

[0015] By adopting the above technical solution, after the snap-fit ​​block is released from the positioning groove, the abutting block abuts against the connecting block under the elastic force of the abutting spring and pushes the connecting block to move towards the direction close to the diamond frame, so that the connecting block can be released from the connecting groove.

[0016] Preferably, the lifting assembly includes a lifting screw and three lifting guide rods rotatably mounted on the transfer frame, a synchronizing rod fixed between the two placement plates, lifting blocks sleeved on the outer periphery of the lifting screw and the outer periphery of the lifting guide rods, the lifting blocks threadedly engaging with the lifting screw, the lifting blocks being fixedly connected to the placement plates, and a drive motor mounted on the transfer frame, the output end of the drive motor being fixedly connected to the top end of the lifting screw.

[0017] By adopting the above technical solution, the drive motor is started, which drives the lifting screw to rotate. The lifting screw drives the lifting block to move vertically, and then drives the two placement plates to move vertically synchronously through the synchronizing rod, so that the angle steel can be aligned with the diamond frame.

[0018] Preferably, the pushing assembly includes a reciprocating lead screw and a guide rod rotatably mounted on the transfer frame. A pushing motor is mounted on the transfer frame, and the output end of the pushing motor is fixedly connected to the end of the reciprocating lead screw. An mounting plate is sleeved on the outer periphery of the reciprocating lead screw and the guide rod. The mounting plate is threadedly engaged with the reciprocating lead screw. An mounting rod passes through the mounting plate, and a pushing plate is fixed at the bottom end of the mounting rod. The pushing plate can abut against the end of the angle steel.

[0019] By adopting the above technical solution, the drive motor is started, which drives the reciprocating screw to rotate. The reciprocating screw drives the mounting plate to move along the length of the angle steel. The mounting plate drives the push plate to move towards the direction of the lifting device. The push plate abuts against the end of the angle steel and pushes the angle steel into the diamond frame, thereby realizing the hanging of the angle steel with high hanging efficiency.

[0020] Preferably, the transfer frame is equipped with two sliding plates, which are sleeved on the outer periphery of the lifting guide rod. The bottom surface of the sliding plate is in contact with the top surface of the lifting block, and a sliding groove is formed on the top surface of the sliding plate. The bottom surface of the push plate is in contact with the inner bottom surface of the sliding groove. Moving grooves are formed on both sides of the push plate. A moving block is slidably installed on the push plate along its own length direction through the moving groove. A moving spring is fixed on the side of the moving block away from the sliding plate. The end of the moving spring away from the moving block is fixedly connected to the inner wall of the moving groove. A limiting groove is formed on the inner wall of the sliding groove. The moving block slides and engages with the sliding plate along the length direction of the sliding plate through the limiting groove.

[0021] By adopting the above technical solution, when the push plate is located in the sliding groove, the moving block is inserted into the limiting groove under the elastic force of the moving spring. The moving block moves along the length direction of the sliding plate in the limiting groove, so that the push plate is not easy to separate from the sliding plate. The push plate always moves along the length direction of the sliding plate so that the push plate can abut against the end of the angle steel on the placement plate, thereby pushing the angle steel to move towards the direction close to the diamond frame.

[0022] Preferably, a magnetic block one is fixed on the bottom surface of the sliding plate, and a magnetic block two is fixed on the top surface of the lifting block, with the magnetic block one and the magnetic block two attracting each other.

[0023] By adopting the above technical solution, magnetic block one and magnetic block two are attracted to each other. When the lifting block moves vertically under the action of the lifting screw, the sliding plate moves synchronously with the lifting block.

[0024] This application provides a hot-dip galvanizing method for angle steel, which adopts the following technical solution:

[0025] Includes the following steps:

[0026] S1. Start the drive motor, the placement plate moves upward, and when the angle steel is aligned with the diamond frame of the first layer from top to bottom, turn off the drive motor.

[0027] S2. Start the drive motor. The push plate abuts against the end of the angle steel and pushes the angle steel to move. The angle steel passes into the diamond frame. After the push plate resets, turn off the drive motor.

[0028] S3. Start the drive motor to reverse, the placement plate will descend, and then the angle steel will be placed into the placement slot. Start the drive motor to rotate forward, the placement plate will move upward, and when the angle steel is aligned with the second layer of diamond frame from the top, turn off the drive motor and start the push motor to insert the angle steel into the diamond frame.

[0029] S4. After inserting the angle steel into the diamond frame from top to bottom, press down the abutment block to disengage the connecting block from the connecting groove, move the lifting device into the galvanizing tank, and galvanize the angle steel.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. Secure the connecting block to the fixing plate to prevent the hanging parts from shaking. Then, use the lifting component to move it upwards to align the angle steel with the diamond frame. Then, use the pushing component to push the angle steel towards the diamond frame so that the angle steel is inserted into the diamond frame and does not shake, resulting in high hanging efficiency.

[0032] 2. Insert the connecting block into the connecting groove, and then insert the snap-fit ​​block into the positioning groove, so that the connecting block is snapped and fixed with the fixing plate, thereby keeping the hanging piece and the three fixing plates relatively fixed, so that the hanger is not easy to shake, so that the angle steel can be hung in the diamond frame.

[0033] 3. Start the drive motor. The drive motor drives the lifting screw to rotate. The lifting screw drives the lifting block to move vertically.
