Abstract
Description
Technical Field
[0001] The utility model relates to a component of an all-steel radial giant tire building machine, in particular to a pressure roller anti-falling device of the giant tire building machine. Background Art
[0002] With the rapid development of science and technology, the industrial manufacturing industry is gradually entering the era of intelligence, and product digital information is becoming increasingly important. In the tire manufacturing industry, tire weight is considered a key tire information. Giant tires weigh over 2 tons. The all-steel giant tire radial building machine (hereinafter referred to as the giant tire building machine) is a key equipment in giant tire manufacturing. It uses a pressure roller behind the tire building drum for rolling.
[0003] The pressure rollers, when the tire cord is wrapped around the steel ring, move along the inclined surface of the guide rail perpendicular to the tire cross-section to the rubber surface for rolling. Because the pressure rollers' movement is at an angle to the horizontal plane, there are safety hazards such as slippage. Furthermore, workers are sometimes required to enter this position to check the rolling effect. Consequently, operator error or equipment failure inevitably lead to the pressure roller frame sliding down the inclined surface and squeezing workers. Utility Model Content
[0004] In response to the shortcomings of the existing technology, the utility model provides a pressure roller anti-fall device for a giant tire forming machine. The pressure roller anti-fall device is arranged on the pressure roller moving seat, and the locking block is pushed into the lock seat by the driving cylinder, which effectively prevents the pressure roller from sliding down, protects the equipment and ensures the safety of the staff. The insertion or withdrawal of the locking block is automatically controlled by the position sensor with high accuracy. In addition, the boss can extend out of the lock seat. In the event of a fault, the pressure roller moving seat will slide down with a small displacement after the locking block is embedded in the lock seat, causing the driving cylinder to be unable to withdraw the locking block, and then it can be clearly judged that there is a fault in the equipment here.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] Compared with the prior art, the present invention has the following beneficial effects:
[0008] This pressure roller anti-fall device is arranged on the pressure roller moving seat. It drives the locking block to be nested in the lock seat by the driving cylinder, effectively preventing the pressure roller from sliding down, protecting the equipment while ensuring the safety of the staff. The insertion or withdrawal of the locking block is automatically controlled by the position sensor with high accuracy. In addition, the boss can extend out of the lock seat. In the event of a fault, the pressure roller moving seat will slide down with a small displacement after the locking block is nested in the lock seat, causing the driving cylinder to be unable to withdraw the locking block, and then it can be clearly judged that there is a fault in the equipment here.

[0015] like Figure 1The figure shows a specific embodiment of the present invention, a giant tire building machine pressure roller anti-fall device, including a cylinder seat 1 installed on the pressure roller movable seat 6. In this embodiment, the cylinder seat 1 is arranged in a rectangular parallelepiped shape. The cylinder seat 1 is detachably mounted on the pressure roller movable seat 6 by bolts. A driving cylinder 2 is provided on the cylinder seat 1. The piston rod end of the driving cylinder 2 is connected to a locking block 3. The locking block 3 includes a pin 3-1 connected to the piston rod end of the driving cylinder 2 and a boss 3-2 provided at the bottom end of the pin 3-1. The diameter of the boss 3-2 is larger than the diameter of the pin, and the boss 3-2 It is arranged perpendicular to the latch 3-1. In order to ensure a firm connection between the boss 3-2 and the latch 3-1, the boss 3-2 and the latch 3-1 are formed integrally in this embodiment. The locking block 3 can be nested in the lock seat 4 installed on the pressure roller movable seat 6. The lock seat 4 matches the locking block 3. In this embodiment, a lock hole 4-1 corresponding to the lock block 3 is provided on the lock seat 4. In order to facilitate the locking block 3 to be inserted into or exited from the lock seat 4, the diameter of the lock hole 4-1 provided on the lock seat 4 is slightly larger than the diameter of the boss 3-2, that is, the boss 3-2 can pass through the lock seat 4 and extend outward. The cylinder seat 1 is also provided with two position sensors 5 connected to the driving cylinder 2. The two position sensors 5 are used to detect whether the lock block 3 is inserted into the lock seat 4 or exits the lock seat 4. The two position sensors 5, the driving cylinder 2 and the pressure roller are all connected to the intelligent control system. In this embodiment, the intelligent control system is set as a PLC controller. The two position sensors 5 detect whether the lock block 3 is inserted into the lock seat 4 or exits the lock seat, and transmit the detected signal to the PLC controller, thereby controlling the driving cylinder 2 to continue to extend the piston rod or retract the piston rod, so as to ensure whether the lock block 3 and the lock seat 4 are closed or open. In this state, the PLC controller also drives or shuts down the movement of the pressure roller according to the position of the locking block 3. In order to effectively protect the safety of the equipment and staff, this embodiment further provides a sensor for detecting the position of the pressure roller moving seat 6 on the molding machine equipment. When the pressure roller moving seat 6 finishes rolling and retreats to the ready position, the PLC controller starts the driving cylinder 2 to nest the locking block 3 into the locking seat 4, so that the pressure roller moving seat 6 cannot move downward, protecting the equipment while also ensuring the safety of the staff. When the pressure roller needs to roll again, the PLC controller starts the driving cylinder 2 to withdraw the locking block from the lock seat 4, so that the pressure roller moving seat 6 moves downward.
[0016] When the utility model is used: the anti-fall device is installed on the giant tire building machine and started. When the pressure roller moving seat 6 finishes rolling and retreats to the ready position, the PLC controller starts the driving cylinder 2 to nest the lock block 3 into the lock seat 4. Figure 4 As shown, the roller movable seat 6 cannot move downward, protecting the equipment while also ensuring the safety of the staff; if the equipment fails, since the diameter of the lock hole 4-1 is slightly larger than the diameter of the boss 3-2, the roller movable seat 6 will continue to slide down to the boss 3-2 and be stuck, as shown in FIG. Figure 3As shown, at this time, the PLC controller cannot start the drive cylinder 2 to withdraw the lock block from the lock seat 4, then it can be clearly determined that the equipment has a fault here; when the pressure roller needs to roll again, the PLC controller starts the drive cylinder 2 to withdraw the lock block 3 from the lock seat 4, as shown Figure 2 As shown, the pressure roller moving seat 6 is moved downward.
