The various technical features in the creation of the utility model can be combined interchangeably without conflicting with each other.
[0030] Reference Figure 1 A structure for realizing safe lifting of an oven hull comprises a safety component 4, a lifting component 1 and a safety trigger. The lifting component 1 is used to lift the upper hull to increase the distance between the upper hull and the lower hull; the safety component 4 is used to lock the lifted hull to prevent the hull from accidentally falling and causing an accident; the safety trigger is used to trigger the safety to lock the hull at a specific moment.
[0031] Reference Figures 1 to 3The lifting assembly 1 includes a lifting drive member, a connecting member and a guiding member. The lifting drive member is fixedly connected to the top of the oven 6; a plurality of connecting members connect the lifting drive member and the four corners of the hull on the oven 6. Specifically, the connecting member is a steel wire rope 13, and the lifting assembly 1 also includes a steel wire guide wheel 14. A plurality of groups of steel wire guide wheels 14 are fixedly arranged at the top of the oven 6, and the steel wire rope 13 is wound around the steel wire guide wheel 14. The steel wire guide wheel 14 is used to guide the steel wire rope 13, change the direction of force on the steel wire rope 13, and can change the length of the steel wire rope 13 and tighten the steel wire rope 13, further ensuring the safety performance in the production process, and is also conducive to reducing the friction and wear of the steel wire rope 13 and extending the service life of the steel wire rope 13. In this embodiment, each steel wire rope 13 is connected by a basket screw, an adjusting nut and a wire clamp rope.
[0032] The guide member includes a plurality of guide rods 12. In the present embodiment, four guide rods 12 are provided. The four guide rods 12 are respectively fixedly connected to the four corners of the hull, and one end of the guide rod 12 away from the upper hull of the oven 6 passes through the top of the oven 6. The guide rod 12 can be lifted and lowered at the top of the oven 6. A limiter 121 is provided at one end of each guide rod 12 away from the upper hull. The limiter 121 is threadedly connected to the guide rod 12. A nut is threadedly connected to the end of the guide rod 12 away from the upper hull. In the present embodiment, the height of the oven 6 is adjusted by adjusting the position of the limiter 121 and the nut, which is conducive to ensuring the production efficiency during the production process.
[0033] Reference Figures 1 to 3 , each guide rod 12 is provided with a set of safety components 4, the safety components 4 include a safety drive and a cushion block 42, the safety drive is fixedly connected to the top of the oven 6, the safety drive is arranged one by one with the guide rod 12, and the safety drive is located on one side of the guide rod 12. Specifically, the safety drive is a safety cylinder 41, and the cushion block 42 is fixedly arranged on the piston rod of the safety cylinder 41. The cushion block 42 is in a "U"-shaped structure, and the opening faces the guide rod 12. When the safety trigger triggers the safety drive to act, the piston rod of the safety cylinder 41 extends, and the "U"-shaped cushion block 42 clamps the guide rod 12. At this time, the limiter 121 abuts against the upper surface of the cushion block 42, and the height of the guide column is fixed, that is, the upper hull is fixed. Under the cooperation of the limiter 121 and the cushion block 42, the possibility of the upper hull falling is effectively reduced, which greatly ensures the safety of the production environment.
[0034] The lifting drive is a lifting cylinder 11, which is fixedly arranged on the top of the oven 6. The piston rod of the lifting cylinder 11 is fixedly connected to a driving connecting plate 111, one end of a steel wire 13 is fixedly connected to the driving connecting plate 111, and the driving connecting plate 111 is slidably connected to the top of the oven 6. When the piston rod of the lifting cylinder 11 extends to drive the driving connecting plate 111 to slide on the top of the oven 6, the steel wire 13 is driven to move, and the upper hull is pulled to lift the upper hull. Specifically, a slide rail 2 for the driving connecting plate 111 to slide is fixedly connected to the top of the oven 6, and a slider 21 is connected to the upper slide. The driving connecting plate 111 is fixedly provided with a connecting seat 112, and the connecting seat 112 is fixedly connected to the slider 21. The driving connecting plate 111 and the slider 21 are connected and fixed by the connecting seat 112.
[0035] Reference Figure 1 and Figure 2 , the safety trigger is a mechanical valve 3, which is fixedly arranged on the top of the oven 6, and the mechanical valve 3 is located near the slide rail 2 and away from the lifting cylinder 11, and the valve switch of the mechanical valve 3 is connected to the driving connecting plate 111, and the mechanical valve 3 is used to control the opening and closing of the safety cylinder 41. Specifically, the valve switch of the mechanical valve 3 is hinged to the connecting seat 112. When the lifting cylinder 11 drives the driving plate to slide to a specific position, the connecting seat 112 drives the valve of the mechanical valve 3 to open, and at this time the safety cylinder 41 is started, and the driving pad 42 clamps the guide rod 12. In this embodiment, the mechanical valve 3 is installed at the extreme position where the piston rod of the lifting cylinder 11 can be extended, so as to ensure that the mechanical valve 3 can be triggered only when the upper hull rises to the highest point, thereby opening the safety. The mechanical valve 3 is set at the extreme position of the lifting cylinder 11 to ensure that the safety component 4 automatically extends to lock the upper hull when the upper hull rises to the highest point, which effectively avoids the possibility of safety accidents caused by the safety component 4 not extending in time when the upper hull reaches the highest point due to operating errors of the operator, and also avoids the possibility of equipment damage caused by the safety component 4 extending prematurely due to operating errors.
[0036] Reference Figures 1 to 4The structure for realizing safe lifting of the hull of the oven 6 also includes an electric control valve 5, which is used to control the action of the safety drive and the lifting drive. In this embodiment, the electric control valve 5 is a three-position four-way valve, which is arranged on the surface of the oven 6. The three-position four-way valve is electrically connected to the lifting cylinder 11, the safety cylinder 41 and the mechanical valve 3. By selecting the three-position four-way valve to different working positions, the action states of the lifting cylinder 11 and the safety cylinder 41 can be controlled respectively. Specifically, the three-position four-way valve is connected to the lifting cylinder 11 through a first air pipe 51, the three-position four-way valve is connected to the mechanical valve 3 through a second air pipe 52, and the mechanical valve 3 is connected to the safety cylinder 41 through a third air pipe. Specifically, the first air pipe 51 and the second air pipe 52 are air pipes of different diameters. In the present embodiment, the outer diameter of the first air pipe 51 is 10 mm (i.e., an air pipe of φ10 specification), and the outer diameter of the second air pipe 52 is 6 mm (i.e., an air pipe of φ6 specification). By setting different types of installation connecting pipes, the possibility of danger caused by installation errors or incorrect posting of switch labels by operators, which may lead to the opening of the insurance and incorrect lifting of the hull, can be effectively avoided, thereby effectively reducing the possibility of safety accidents caused by installation errors.
[0037] The utility model also provides:
[0038] An oven 6 comprises a structure as described above to achieve safe lifting and lowering of the oven hull.
[0039] The implementation principle of the utility model is:
[0040] When the hull needs to be lifted, the three-position four-way valve is turned to the hull lifting position, the piston rod of the lifting cylinder 11 extends, pushing the driving connecting plate 111 to slide on the slide rail 2, and the driving connecting plate 111 drives the wire rope 13 to move, thereby realizing the lifting of the upper hull. When the upper hull is raised to the highest position, the driving connecting plate 111 pushes the mechanical valve 3 to open. At this time, the mechanical valve 3 is in an open state, so that the piston rod of the safety cylinder 41 extends, and the driving pad 42 clamps the guide rod 12 to lock the upper hull.
[0041] When the upper hull needs to be lowered, it is only necessary to turn the three-position four-way valve to the hull lowering position. At this time, the mechanical valve 3 is reset, and the safety component 4 will quickly retract (in actual application, the retraction speed of the safety component 4 can be controlled by the flow rate of the speed regulating valve and the mechanical valve 3 itself), and the upper hull will slowly descend under its own gravity (the descending speed can be controlled by adjusting the speed regulating valve on the lifting cylinder 11), and the upper hull will descend to the lowest position under the action of its own weight. When it is not needed, turn the three-position four-way valve to the middle position.
[0042] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
