Abstract
Description
Technical Field
[0001] This utility model relates to the field of automated equipment protection technology, specifically to a human-machine interface protection device for ductile iron pipeline operators. Background Technology
[0002] The ductile iron pipe production site is equipped with a large number of automated production equipment. The operation of these machines has greatly improved production efficiency, ensuring product consistency while significantly increasing the output of ductile iron pipes.
[0003] PLCs and other control devices are the brains of these automated machines, while numerous sensors distributed across the site form a neural network. The human-machine interface (HMI), acting as its ears and mouth, serves as a crucial bridge for information exchange between the equipment and personnel. Due to the precision of the equipment, its price is also quite high. Pipe casting sites often experience harsh working conditions, with significant amounts of sparks flying during production. When workers wash equipment or the floor, sprayed water droplets also occur. If these molten iron or droplets come into contact with the HMI, they can seep into its interior, damaging the equipment and causing downtime. Furthermore, during material handling or cleaning, sometimes due to worker negligence, materials or tools may collide with the HMI panel, potentially damaging the screen and causing unnecessary losses.
[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

A locking block is provided at the end of the rotating rod, and the locking block is disposed in the limiting section and locking with the guide section.
[0011] Preferably, the protective plate has a chamfered groove on the edge corresponding to the connecting component, so that the thickness of the protective plate gradually increases in the direction away from the fixing post, and the chamfered groove is provided on the end face away from the sealing strip.
[0012] Preferably, the extension length of the fixing post is less than the sum of the thickness of the protective plate and the thickness of the sealing strip.

Detailed Implementation
[0023] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.
[0024] Example 1
[0025] like Figure 1 and Figure 2 As shown, Figure 1 This is a front view of the structure of the ductile iron pipe operator human-machine interface protection device; Figure 2 This is a structural side view of the ductile iron pipe operator human-machine interface protection device.
[0026] The ductile iron pipe operator human-machine interface protection device of this utility model is used for human-machine interface 1, which is set on operation panel 2. The ductile iron pipe operator human-machine interface protection device of this utility model includes a protective plate 3, a hinge 4, and a connecting component 5. The protective plate 3 is a rectangular plate-shaped piece made of transparent material. One side of the protective plate 3 is rotatably connected to the operation panel 2 through the hinge 4, and the other side is detachably connected to the operation panel 2 through the connecting component 5. The hinge 4 and the connecting component 5 are respectively set on both sides of the human-machine interface 1, so that the human-machine interface 1 can be protected by the protective plate 3.
[0027] Generally, the hinge 4 is located at the upper end of the protective plate 3, and the connecting component 5 is located at the lower end of the protective plate 3, so that the protective plate 3 fits against the operation panel 2 under its own weight, thereby protecting the human-machine interface 1.
[0028] A sealing strip 6 is provided on the end face of the protective plate 3 near the operation panel 2. The sealing strip 6 extends in a ring around the human-machine interface 1 to form a closed frame structure. The protective plate 3 is connected to the operation panel 2 in close contact through the sealing strip 6, and the human-machine interface 1 is located inside the sealing strip 6 of the frame structure. The sealing strip 6 prevents gaps between the protective plate 3 and the operation panel 2, thus ensuring the protection effect of the human-machine interface 1.
[0029] Generally, the sealing strip 6 is made of elastic rubber. When the protective plate 3 closes under its own weight, the sealing strip 6 contacts the operation panel 2, thereby reducing the impact force of the protective plate 3 falling and playing a buffering effect when closing.
[0030] This invention can largely protect the human-machine interface 1 from the harsh working conditions of the casting site, extend its service life, save on the increased costs caused by accidental damage, and is easy to install. It does not affect the operator's ability to view interface parameters and monitor the equipment's working status in real time. Touch operation is also convenient; simply lift up the operation panel 2.
[0031] Example 2
[0032] like Figure 3 As shown, Figure 3 This is a connection structure view of Embodiment 2 of the connecting component; the connecting component 5 includes a fixing post 51, a rotating rod 52, and a pressure plate 53. The pressure plate 53 is fixedly disposed at one end of the rotating rod 52. The fixing post 51 is vertically fixed on the operation panel 2. A connecting hole is provided in the fixing post 51. The rotating rod 52 is disposed in the connecting hole and can rotate freely around its own axis within the connecting hole. By rotating the rotating rod 52, the pressure plate 53 can be disposed on one side of the protective plate 3, thereby pressing and adhering the protective plate 3 to the operation panel 2 through the pressure plate 53 to achieve the fixing effect of the protective plate 3.
[0033] Preferably, the connecting hole includes a guide section 54 and a limiting section 55. The cross-sectional diameter of the guide section 54 is the same as the cross-sectional diameter of the rotating rod 52, thereby ensuring that the rotating rod 52 can move freely within the connecting hole. The cross-sectional diameter of the limiting section 55 is larger than the cross-sectional diameter of the guide section 54. A locking block 56 is provided at the end of the rotating rod 52. The locking block 56 is disposed within the limiting section 55 and engages with the guide section 54, thereby enabling the axial movement of the rotating rod 52 within the connecting hole.
[0034] The protective plate 3 is provided with an angled groove 31 on the edge corresponding to the connecting component 5, so that the thickness of the protective plate 3 gradually increases in the direction away from the fixing post 51. The angled groove 31 is provided on the end face away from the sealing strip 6, so that the protective plate 3 can be gradually pressed and fixed to the operation panel 2 by rotating the pressure plate 53.
[0035] Preferably, the extension length of the fixing post 51 is slightly smaller than the sum of the thickness of the protective plate 3 and the thickness of the sealing strip 6, so that when the protective plate 3 is pressed by the pressure plate 53, the sealing strip 6 will be squeezed and deformed, and the rebound force of the sealing strip 6 will improve the stability of the pressure plate 53 on the protective plate 3.
[0036] Preferably, the snap-fit block 56 is threaded to the end of the rotating rod 52. By rotating the snap-fit block 56 and the rotating rod 52 relative to each other, the position of the snap-fit block 56 on the rotating rod 52 can be adjusted, thereby realizing the installation and fixation between the fixing post 51 and the rotating rod 52.
[0037] Example 3
[0038] like Figure 4 As shown, Figure 4 This is a connection structure view of Embodiment 3 of the connecting assembly. In this embodiment, the connecting assembly 5 further includes a spring 57, which is disposed within the limiting section 55 and sleeved on the outside of the rotating rod 52. The two ends of the spring 57 are respectively in contact with the end of the guide section 54 and the snap-fit block 56 to provide elastic repulsive force. The pressure plate 53 can be more easily pressed onto the protective plate 3 by axially pulling it, and the guide section 54 ensures stable axial movement of the rotating rod 52.
[0039] like Figure 5 As shown, Figure 5 The diagram shows the structure of the snap-fit block. Preferably, the snap-fit block 56 is disc-shaped, with a mounting hole 561 at its center. The rotating rod 52 is threadedly connected to the mounting hole 561, and both sides of the snap-fit block 56 are provided with disassembly grooves 562. By inserting a U-shaped fork into the two disassembly grooves 562, it is easy to screw the snap-fit block 56 into place.
[0040] The limiting section 55 may be provided with internal threads, and the mounting bolts can be detachably installed on the operation panel 2 through the threaded connection of the limiting section 55. Similarly, the fixing post 51 may also be fixed to the operation panel 2 by bonding or welding.
[0041] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
