Description

Technical Field

[0001] The utility model relates to the technical field of cooling beds, in particular to a cooling bed head wheel protective cover which is easy to fold up. Background Art

[0002] During the casting process, the sand mold absorbs a lot of heat after pouring and becomes very hot. If these hot sands are not cooled, they cannot be directly used for the next round of casting, and may even cause damage to the equipment. The cooling bed quickly reduces the temperature of the hot sand to an acceptable range through air cooling, water cooling, etc. The cooling bed head wheel is an important component of the cooling bed equipment. The cooling bed head wheel is a key component on the cooling bed used to support and guide the conveyor belt or workpiece movement, and is usually located in the head part of the cooling bed.

[0003] The working principle of the head wheel of the cooling bed is relatively simple. It mainly supports and guides the movement of the conveyor belt or workpiece through the rotation of the wheel body.

[0030] The top end surfaces of the second protective cover 605 and the first protective cover 601 are both embedded with a buffer energy-absorbing component 8, and the buffer energy-absorbing component 8 includes a buffer pad 801 embedded in the top end surfaces of the second protective cover 605 and the first protective cover 601, and a damper 802 and an assembly spring 803 are fixedly connected between the bottom end surface of the buffer pad 801 and the second protective cover 605 and the first protective cover 601, and the assembly spring 803 is sleeved on the outside of the damper 802.

[0031] By adopting the above technical solution, when in use, the first protective cover 601 can rotate on the rotating shaft 604 through the first connecting side plate 602 and the first connecting sleeve 603, so that it can cover one side of the cooling bed head wheel 4. Similarly, the second protective cover 605 can rotate on the rotating shaft 604 through the second connecting side plate 606 and the second connecting sleeve 607, thereby increasing the protection area of ​​the protective cover. When splashing sand and gravel collide with the protective cover, the sand and gravel hit the buffer pad 801, which is made of polystyrene foam plastic. The buffer pad 801 It can buffer and absorb the force generated by the impact of sand and stones, and the buffer pad 801 can transfer the force to the damper 802 and the assembly spring 803. Through the cooperation of the three, the force of the impact of sand and stones can be removed, avoiding the rebound and continued splashing of sand and stones after the impact, thereby causing damage to surrounding equipment or posing a safety hazard to operators. At the same time, the shielding of the protective cover assembly 6 can also protect the cooling bed head wheel 4, avoiding the head wheel 4 from being directly impacted by splashing sand and stones, which may cause its wear to increase, shorten its life, and even cause failures.

[0032] Specifically, Figures 1 to 4As shown, a second scraper 10 is fixedly installed on the bottom end surface of the first protective cover 601 near the top end surface of the second protective cover 605, and a first scraper 9 is fixedly installed on the bottom end surface of the supporting cover frame 5 near the top end surface of the first protective cover 601; a second blocking baffle 12 is fixedly installed on the top end surface of the first protective cover 601 near the right side of the first scraper 9, and a first blocking baffle 11 is fixedly installed on the top end surface of the second protective cover 605 near the right side of the second scraper 10; a bearing seat 2 is fixedly installed on the top end of the supporting seat 1 located on the inner side of the supporting cover frame 5, a bearing 3 is fixedly installed inside the bearing seat 2, a head wheel 4 is rotatably installed inside the bearing 3, and the head wheel 4 can stably rotate and work on the supporting seat 1 through the bearing 3 and the bearing seat 2. A retractable and extendable regulating component 7 is commonly provided on the front side wall of the second protective cover 605 and the front side wall of the bearing cover frame 5. The retractable and extendable regulating component 7 comprises an assembly shaft 701 fixedly mounted on the lower side of the front end surface of the second protective cover 605, and a connecting ring 702 is rotatably sleeved on the assembly shaft 701; an assembly seat 705 is fixedly mounted on the front side wall of the bearing cover frame 5, a rotating ball groove 706 is provided inside the assembly seat 705, a chimeric ball 707 is rotatably mounted inside the rotating ball groove 706, a winding rod 704 is inserted inside the chimeric ball 707, and a chimeric locking plate 710 fixedly mounted on the front side wall of the bearing cover frame 5 is provided above the assembly seat 705; a pressure plate 708 is slidably sleeved on the outer wall of the winding rod 704, a spring 709 is fixedly mounted on the side of the pressure plate 708 away from the assembly seat 705, the spring 709 is sleeved on the outside of the winding rod 704, and a rope 703 is connected between the winding rod 704 and the connecting ring 702.

[0033] By adopting the above technical solution, when it is necessary to open the protective cover for protection, when the first protective cover 601 is unfolded to the maximum extent, the second blocking baffle 12 on the first protective cover 601 can reach the maximum unfolding angle by being blocked by the first scraper 9 on the bottom end face of the bearing cover frame 5. Similarly, when the second protective cover 605 is unfolded to the maximum extent, the first blocking baffle 11 on the second protective cover 605 can reach the maximum unfolding angle by being blocked by the second scraper 10 on the bottom end face of the first protective cover 601. When it is necessary to adjust the unfolding angle of the protective cover, the winding rod 704 is turned, and the winding rod 704 can rotate in the rotating ball groove 706 through the embedded ball 707. The rotation of the winding rod 704 can wind the rope 703, so that the assembly shaft 701 and the second protective cover 605 can be pulled by the rope 703 to move, and the second protective cover 605 can rotate on the rotating shaft 604 through the second connecting side plate 606 and the second connecting sleeve 607, so that the protective cover can be opened. When the protective cover is continuously rotated to open, the first protective cover 601 can be pushed to rotate and reel up through the obstruction of the assembly shaft 701. When the reeling and unfolding angle of the protective cover is at a suitable position, the winding rod 704 is turned upward to clamp the winding rod 704 into the interlocking lock plate 710. The elasticity of the spring 709 pushes the pressing plate 708 to be close to the interlocking lock plate 710, so as to ensure the stability of the clamping point, and then the unfolding angle of the protective cover of the head wheel 4 of the cooling bed can be adjusted. By adjusting the unfolding angle of the protective cover, it can be better adapted to different working scenes and needs; for example, when a larger protection range is required, increasing the unfolding angle can effectively prevent splashes of sand, coolant, etc. from damaging the head wheel 4; at the same time, when reeling up, the second scraper 10 and the first scraper 9 can scrape and clean the top surfaces of the second protective cover 605 and the first protective cover 601, so as to avoid the sand and other objects embedded on the buffer plate 801 affecting the unfolding and closing of the first protective cover 601 and the second protective cover 605.

[0034] Working principle: When the cooling bed head wheel 4 is working, it is necessary to open the protective cover for protection, loosen the rope 703 wound on the winding rod 704, and the first protective cover 601 and the second protective cover 605 can be unfolded to the maximum extent under the action of their own gravity to protect the cooling bed head wheel 4. The second blocking baffle 12 on the first protective cover 601 can reach the maximum unfolding angle through the blocking of the first scraper 9 on the bottom end surface of the bearing cover frame 5, and the first blocking baffle 11 on the second protective cover 605 can reach the maximum unfolding angle through the bottom end surface of the first protective cover 601. The second scraper 10 blocks and reaches the maximum deployment angle. When the deployment angle of the protective cover needs to be adjusted, the winding rod 704 is toggled, and the winding rod 704 can rotate in the rotating ball groove 706 through the embedded ball 707. The winding rod 704 rotates to wind the rope 703, so that the assembly shaft 701 and the second protective cover 605 can be pulled by the rope 703 to move. The second protective cover 605 can rotate on the rotating shaft 604 through the second connecting side plate 606 and the second connecting sleeve 607, so that the protective cover can be opened. When the second protective cover 605 is continuously rotated to open, the first protective cover 601 is pushed to rotate and reel up through the blocking energy of the assembly shaft 701. When the reeling and unfolding angle of the protective cover is at a suitable position, the winding rod 704 is turned upward to insert the winding rod 704 into the interlocking lock plate 710. The elasticity of the spring 709 pushes the pressure plate 708 and the interlocking lock plate 710 to be close to each other, so as to ensure the stability of the clamping point. When splashing sand and gravel hit the protective cover, the sand and gravel hit the buffer pad 801, which is made of polystyrene foam plastic. The buffer plate 801 is made of material, and can buffer and absorb the force generated by the impact of sand and stones, and the buffer plate 801 can transfer the force to the damper 802 and the assembly spring 803. Through the cooperation of the three, the force of the impact of sand and stones can be removed. At the same time, when winding, the second scraper 10 and the first scraper 9 can scrape and clean the top surfaces of the second protective cover 605 and the first protective cover 601, so as to avoid sand and stones embedded in the buffer plate 801 affecting the deployment and closing of the first protective cover 601 and the second protective cover 605.
