The anti-dropping device of the small box clamp for the screw head part of the unit.

The utility model is realized by adopting the following technical scheme: a device for preventing the small box fixture from falling off of the screw head part of the aluminum electrolysis multifunctional unit, including an anti-drop hanging plate whose upper end is movable hinged on both sides of the screw head part, an upper end and a screw The guide shaft fixed at the center of the top of the head part and the opening cylinder fixed on the top of the screw head part, the guide shaft is equipped with a guide sleeve, a return spring and a lock nut threaded with the guide shaft from top to bottom, and the return spring The upper end is tightened with the bottom of the guide sleeve, and the lower end is tightened with the lock nut. There are transmission rods on both sides of the guide sleeve. .

In order to further optimize the structure of the shedding device and improve its functions, the utility model has also made the following improvements. The anti-detachment hanging plate is hinged to both sides of the screw head part through a pin shaft, which is convenient for opening or contracting left and right; The lower ends of the two anti-off scrapers are provided with an anti-off hook plate that cooperates with the small box fixture so that it can be better locked with the small box fixture and prevent the small box fixture from falling off; the opening cylinder There is a solenoid valve in series on the electric control circuit of the electric control circuit, the operator can complete the whole operation process by controlling the opening and closing of the solenoid valve, and realize the locking and falling off of the anti-falling device and the small box fixture.

The utility model can completely prevent the small box clamps from falling off, solve the problems that the original twisting head parts cannot afford the small box clamps or the small box clamps are easy to fall off, and eliminate the possibility of smashing and injuring personnel and damage caused by the small box clamps falling off. equipment security risks. The anti-falling device is easy to install and disassemble, has low maintenance and manufacturing costs, is simple to operate, has strong practicability, and has good promotion value and use value.

Detailed ways

An anti-dropping device for small box fixtures of the twisting head part of an aluminum electrolysis multifunctional unit, as shown in Figure 1, comprising an anti-dropping hanging plate 3 whose upper end is movably hinged on both sides of the screwing head part 1, the upper end and the screwing head part The guide shaft 6 fixed at the center of the top (as shown in Figure 3) and the opening cylinder 5 fixed on the top of the screw head part (as shown in Figure 8), the anti-drop hanging plate 3 and the screw head part 1 through the pin shaft 9 Both sides are hinged, as shown in Figures 4 and 5, the lower ends of the two anti-off scrapers are provided with an anti-off hook plate 10 that cooperates with the small box fixture, and guide sleeves 2 are sequentially assembled on the guide shaft from top to bottom (as shown in Fig. 6 and 7), the return spring 7 and the lock nut 8 threaded with the guide shaft, the upper end of the return spring is pressed against the bottom of the guide sleeve, the lower end is pressed against the lock nut, and the two sides of the guide sleeve are movably connected with the transmission rod 4 (As shown in Figure 2), the ends of the two transmission rods are respectively connected to the corresponding anti-slip hanging plates, and the piston rod for opening the cylinder is connected to the guide sleeve. An electromagnetic valve is connected in series on the electrical control circuit that opens the cylinder 5 .

The above structural components can be manufactured in the following ways,

The anti-drop hanging plate is welded by stainless steel plate, and is fixed on both sides of the screw head with a pin shaft. The anti-drop hanging plate can move left and right.

The guide shaft is made of one end of round steel with a screw, one end is fixed on the top of the screw head part, the guide sleeve and the return spring are installed in the middle, and locked with a lock nut, it acts as a guide when the anti-dropping plate is opened to prevent transmission The device is offset, and at the same time it plays the role of resetting the anti-drop hanging plate.

The guide sleeve is installed on the guide shaft, and it cooperates with the opening cylinder, return spring, transmission device, etc. to realize the opening and reset of the anti-drop hanging plate.

The back-moving spring is sleeved on the guide shaft, one end of which is fixedly abutted on the guide sleeve, and the other end is abutted on the lock nut, which mainly plays the role of resetting the anti-off hanging plate.

The transmission rod is made of round steel, one end is fixed on the guide sleeve, and the other end is fixed on the anti-detachment plate. The opening and closing of the anti-detachment plate is mainly controlled by the movement of the guide sleeve, so as to hold the small box clamp and release the small box. Box fixture function.

The base of the opening cylinder is fixed on the top of the screw head part, and the piston rod of the cylinder is connected to the guide sleeve, and the function of automatically controlling the opening of the anti-drop hanging plate is realized through the air circuit.

During the pole changing operation, when the small box fixture is loosened, the anti-falling device will automatically hang the small box fixture shaft along with the screwing head part, and lock the small box fixture to prevent the small box fixture from falling off role. After installing the new pole and tightening the small box fixture, the piston rod of the open cylinder is pushed down by controlling the solenoid valve, pushing the guide sleeve to move downward along the guide shaft, and then the transmission rods on both sides of the guide sleeve are stretched outward. Open, drive the anti-off hanging plates on both sides to also open outwards, the screw head parts rise, break away from the small box fixture, the control solenoid valve is de-energized, and the anti-off hanging plates reset automatically under the action of the return spring.
