AI Technical Summary
The existing tire vulcanization machine tire gripper lacks braking and safety protection measures during the lifting process, which can easily cause injury to staff.
A tire vulcanizing machine tire gripper is designed, using a combination of a photoinductor and a programmable controller. By detecting whether there are people under the tire gripper, the tire gripper rise is automatically controlled to avoid contact with people.
It realizes automatic rise when there are personnel under the tire gripper, ensuring the safety of staff and avoiding potential injuries.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of tire vulcanizing equipment, in particular to a tire gripper of a tire vulcanizing machine. Background Art
[0002] As we all know, when the tire vulcanizer is vulcanizing, the tire is grabbed by the tire grabber, and the lifting of the tire grabber is controlled by a one-way water cylinder. When water enters the water cylinder cavity, the tire grabber rises, and when water flows out of the cavity, the tire grabber descends by its own gravity. Except for the emergency stop button on the control cabinet and the tire grabber lifting button, no braking and safety protection measures are taken. If a worker works under the tire grabber, it is easy to cause accidental injury. Summary of the invention
[0003] In order to overcome the deficiencies of the prior art, the utility model provides a tire gripper for a tire vulcanizer. When a worker is working under the tire gripper, the tire gripper can be lifted up.
[0004] The technical solution adopted by the utility model to solve the technical problem is: a tire gripper for a tire vulcanizer, provided with a tire gripper fixing plate, eight clamping claws are fixed on the tire gripper fixing plate through bolt holes and bolts thereon, and the utility model is characterized in that a clamping claw side plate is fixed to the side of the clamping claw, an edge switch is installed at the lower end of the clamping claw, a photoelectric sensor is installed inside the edge switch, the photoelectric sensor is connected to the input terminal of a programmable controller, and the output terminal of the programmable controller is connected to the control end of a one-way water cylinder.
[0005] The beneficial effect of the utility model is that it can detect whether there is a person staying under the tire grabber, and transmit a corresponding signal to realize the upward movement of the tire grabber, thereby ensuring the safety of the person under the tire grabber. BRIEF DESCRIPTION OF THE DRAWINGS
[0006] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0007] Figure 1 A schematic structural diagram of the utility model.
[0008] Figure 2 It is a schematic diagram of the clamping claw of the utility model.
[0009] In the figure, 1. clamping claw, 2. bolt hole, 3. clamping claw side plate, 4. edge switch, 5. tire grabber fixing plate. DETAILED DESCRIPTION
[0010] In the figure, the utility model is provided with a tire grabber fixing plate 5, eight clamping claws 1 are fixed to the tire grabber fixing plate 5 through four bolt holes 2 and bolts thereon, a clamping claw side plate 3 is fixed to the side of the clamping claw 1, an edge switch 4 is installed at the lower end of the clamping claw 1, a photoelectric sensor is installed inside the edge switch 4, the photoelectric sensor is connected to the input terminal of the programmable controller, and the output terminal of the programmable controller is connected to the control end of the one-way water cylinder.
[0011] When there is a worker working under the tire grabber and the tire grabber descends, when the clamping claw 1 is about to collide with the worker, the edge switch 4 first contacts the worker, the internal photoelectric sensor switch is closed, and the corresponding programmable controller receives and processes the signal to control the one-way water cylinder of the tire grabber to move, so that the tire grabber rises and moves away from the worker.
Claims
1. A tire gripper for a tire vulcanizer, provided with a tire gripper fixing plate, eight clamping claws are fixed to the tire gripper fixing plate through bolt holes and bolts thereon, wherein: A clamping claw side plate is fixed to the side of the clamping claw, an edge switch is installed at the lower end of the clamping claw, a photoelectric sensor is installed inside the edge switch, the photoelectric sensor is connected to the input terminal of the programmable controller, and the output terminal of the programmable controller is connected to the control end of the one-way water cylinder.
