Description

Technical Field

[0001] This utility model relates to the field of tire vulcanizing equipment, specifically a device for preventing the boom of a hydraulic vulcanizing machine from falling off. Background Technology

[0002] As is well known, a hydraulic vulcanizing machine is a relatively advanced tire vulcanizing equipment. The vulcanizing machine boom is an important component in the vulcanizing machine. Its function is to support the pressurization action of the vulcanizing machine. When the vulcanizing machine is in the mold closing position and mold closing force is required, the boom moves in to support between the pressurizing cylinder and the mold plate. After vulcanization, the boom needs to rotate out so that the vulcanizing machine can open the mold and leave enough space for tire loading and unloading. The vulcanizing machine boom is driven by the air cylinder to rotate in and out. Frequent in and out rotation can easily cause fatigue breakage of the boom cap screw. If maintenance is not timely and the broken cap is not replaced in time, the boom cap will fall off and cause the boom to suddenly fall from the air, posing a great safety hazard. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a hydraulic vulcanizing machine anti-boom fall device to prevent the boom from falling from a height and posing potential risks to people or equipment.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a hydraulic vulcanizing machine anti-boom fall device, which is provided with a boom outer sleeve, a connecting frame horizontally welded to the outer side of the boom outer sleeve, a rotating shaft vertically fixed to the end of the connecting frame, a cylinder connecting body horizontally fixed to the upper end of the rotating shaft, and the end of the cylinder connecting body hinged to the cylinder rod of the horizontally set cylinder. The feature is that the boom is inserted inside the boom outer sleeve, an upper boom cover is fixed to the top of the boom by a boom upper cover fixing screw, a lower boom cover is fixed to the bottom of the boom by a lower boom cover fixing screw, screw holes are machined on the two cylinder walls at the lower end of the boom outer sleeve, and boom adjusting screws are screwed into the screw holes. A lifting cylinder is fixed to the lower part of the upper boom cover, and the telescopic rod of the lifting cylinder is fixed to the boom outer sleeve. A vulcanizing machine disc is fixed to the lower end of the lower boom cover, and a boom anti-fall screw is fixed to the boom at the upper part of the boom outer sleeve.

[0005] The beneficial effects of this utility model are that it eliminates potential hazards in the equipment and improves the safety of equipment use. Attached Figure Description

[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0007] Figure 1 This is a schematic diagram of the structure of the present invention.

[0008] In the diagram: 1. Cylinder, 2. Cylinder connector, 3. Rotary shaft, 4. Connecting frame, 5. Upper cap of boom, 6. Upper cap fixing screw of boom, 7. Lifting cylinder, 8. Anti-fall screw of boom, 9. Boom, 10. Outer sleeve of boom, 11. Adjusting screw of boom, 12. Lower cap of boom, 13. Lower cap fixing screw of boom, 14. Large disc of vulcanizing machine. Detailed Implementation

[0009] In the figure, this utility model includes a boom sleeve 10. A connecting frame 4 is horizontally welded to the outer side of the boom sleeve 10. A rotating shaft 3 is vertically fixed to the end of the connecting frame 4. A cylinder connector 2 is horizontally fixed to the upper end of the rotating shaft 3. The end of the cylinder connector 2 is hinged to the cylinder rod of a horizontally arranged cylinder 1. The cylinder 1 drives the boom sleeve 10 to rotate in and out. A boom 9 is inserted inside the boom sleeve 10. An upper boom cover 5 is fixed above the boom 9 by upper boom cover fixing screws 6. A lower boom cover 12 is fixed by upper boom cover fixing screws. 13 is fixed below the boom 9. Screw holes are machined on both sides of the lower end of the boom outer sleeve 10, and boom adjusting screws 11 are screwed into these holes. The boom adjusting screws 11 can adjust the gap between the boom 9 and the boom outer sleeve 10. A lifting cylinder 7 is fixed to the lower part of the upper boom cover 5. The extension rod of the lifting cylinder 7 is fixed to the boom outer sleeve 10, and the lifting cylinder 7 can drive the boom 9 to move up and down. A vulcanizing machine disc 14 is fixed to the lower end of the lower boom cover 12. A boom anti-fall screw 8 is fixed to the boom 9 above the boom outer sleeve 10. When the upper boom cover fixing screw 6 breaks and the upper boom cover 5 falls off, the boom anti-fall screw 8 can catch the boom 9 in time, preventing the boom 9 from falling from a height of about 3 meters, thus preventing potential risks to personnel or equipment and playing a preventative role.
