Description

Technical Field

[0001] The utility model relates to the technical field of metallurgical strip galvanizing, in particular to a strip anti-collision device for a strip hot-dip galvanizing unit. Background Art

[0002] Steel is the most widely used metal in the world at present. However, steel materials are prone to rust in air, water or soil, that is, they are prone to corrosion. Due to metal corrosion, it often affects the service life and effect of relevant machines or equipment. Sometimes, due to continuous corrosion, serious accidents may also occur to machines or equipment, causing unexpected losses. To reduce the corrosion of steel materials, various anti-corrosion methods have been adopted, among which the method of coating a protective layer on the surface of steel is the most commonly used one.

[0003] The galvanized steel sheets produced by a strip continuous hot-dip galvanizing line have good corrosion resistance. The production process of the hot-dip galvanizing unit is that the strip comes out of the annealing furnace and then enters the zinc pot. The molten zinc liquid in the zinc pot is at 450 - 600 °C. After the strip enters the zinc liquid, zinc adheres to its surface. The strip turns and rises vertically through the sink rolls in the zinc pot. When leaving the zinc pot, the excess zinc liquid is scraped off by the air blowing action of the air knife, and the zinc liquid is evenly coated on the surface of the strip. However, due to the air flow of the air knife, edge thickening defects will occur at the edges of the strip. To solve the edge thickening defects of the strip, the main method is to add edge baffles on both sides of the strip. The strip will swing during the production process, and the edge baffles need to follow the swing. Sometimes, due to the irregular swing of the strip, the strip may collide with the edge baffles, resulting in equipment failures and even major accidents such as strip breakage.

[0009] The following further details the present utility model in conjunction with the drawings and embodiments:

[0010] Figure 1Schematic structural diagram of the strip anti-collision device for the strip hot-dip galvanizing unit of the present utility model;

[0011] Figure 2 is Figure 1 top view of. Specific implementation mode

[0012] For example of implementation Figure 1 and Figure 2 As shown in, the strip anti-collision device for the strip hot-dip galvanizing unit of the present utility model includes a mounting seat 1, a sliding seat 3, a supporting wheel 6, a spring plunger 10, a fixing block 9, a trigger block 8, a microswitch 5, side baffles 2, a front baffle 7, a screw rod 4, an adjusting knob 11 and a locking handle 12 which are arranged above the side baffles. A slide rail is arranged on one side of the mounting seat 1. The sliding seat 3 is arranged on the slide rail. The front end of the screw rod 4 is in threaded connection with the sliding seat 3, and the rear end is movably connected with the mounting seat 1. The adjusting knob 11 is fixedly arranged on the screw rod 4. The sliding seat 3 is provided with a notch. The supporting wheel 6 is arranged in the notch of the sliding seat 3 through a wheel shaft 61. The front baffle 7 is arranged on both sides of the sliding seat 3 and is provided with a long slot. The wheel shaft 61 of the supporting wheel 6 passes through the long slot of the front baffle 7. The fixing block 9 is arranged outside the front baffle 7. The spring plunger 10 is arranged on the fixing block 9 and the front end abuts against the end of the wheel shaft 61 of the supporting wheel 6. The trigger block 8 is arranged at one end of the wheel shaft 61 of the supporting wheel 6. The rear part of the side baffle 2 is arranged on both sides of the mounting seat 1, and the front part is located at the front end of the slide rail of the mounting seat 1. The microswitch 5 is arranged on the side baffle 2 and is close to the trigger block 8. The locking handle 12 is screwed into the side baffle 2 and the front end abuts against the screw rod 4.

[0013] Preferably, the bottom surface of the trigger block 8 is an inclined surface 81, and the trigger end of the microswitch 5 is a roller 51. When the trigger block 8 abuts against the microswitch 5, the inclined surface 81 contacts the roller 51. By contacting the roller with the inclined surface, the reliability of the microswitch action is improved.

[0014] Preferably, the microswitch 5 is a multi-group normally open switch contact. When the trigger block 8 abuts against the trigger end of the microswitch 5, the multi-group normally open switch contacts of the microswitch 5 are closed, and the closing signal is transmitted to the controller of the side baffle. The multi-group normally open switch contacts ensure the reliable transmission of the collision signal and avoid signal errors caused by poor contact of a single contact.

[0015] By installing this anti-collision device on the side baffle, the side baffle can effectively avoid the impact of the strip steel, thus protecting the safety of the equipment. The mounting seat is fixed above the side baffle, the supporting wheel is placed in the notch of the sliding seat, the trigger block is connected to the shaft end on one side of the supporting wheel, the spring plunger presses against the axle of the supporting wheel through the fixing seat, the supporting wheel is arranged between the front baffles on both sides, and the initial position of the supporting wheel is located at the front end of the long slot of the front baffle. The microswitch is installed on the side of the sliding seat through the side baffle and slightly contacts the trigger block.

[0016] During the actual application of this device, after rotating the adjustment knob to adjust the sliding seat to a suitable position through the screw, rotate the locking handle to lock the position of the sliding seat on the slide rail. During the operation of the strip steel, since the trigger block and the axle of the supporting wheel are fixed by bolts, the sliding seat is provided with a notch, the supporting wheel can slide back and forth in the notch, the axle of the supporting wheel can slide in the long slot of the front baffle, and the initial thrust is provided by the spring plunger. When the strip steel collides with the supporting wheel, it overcomes the initial thrust provided by the spring plunger and drives the axle of the supporting wheel and the trigger block to move together. In this way, the supporting wheel will drive the trigger block to trigger the microswitch, and the microswitch feeds back the signal to the controller of the side baffle. The controller responds in time and quickly opens the side baffle to avoid the occurrence of collision.

[0017] After the actual installation and application of this device, it is proved that this device has a simple structure, is convenient to install, has reliable actions, stable operation, and is convenient to maintain, and can well solve the problem of the strip steel colliding with the side baffle.
