Description

Technical Field

[0001] The utility model relates to the technical field of infrared grating access control, in particular to an access control device for aggregate bins of a mixing station based on infrared gratings. Background Art

[0002] Infrared grating access control is an access control device that monitors and controls entrances and exits through infrared grating sensors. It monitors the passage of the door by setting up one or more infrared gratings composed of infrared transmitters and receivers. In the aggregate silo of the mixing plant, infrared grating access control will be used to manage the vehicles entering and leaving. When a vehicle passes through the infrared grating, the infrared grating access control will send a signal for identification and verification, thereby realizing the control and management of the access control.

[0003] The above-mentioned and existing related technologies have the following defects: the infrared grating access control is usually installed on both sides of the wall of the silo door of the mixing station for use. In the actual production process, when the infrared grating access control is suspended, the infrared grating access control is in an exposed state. At this time, the infrared grating access control is easily damaged by external collisions, resulting in the service life of the infrared grating access control being shortened.

[0004] Therefore, we propose an access control device for aggregate silo of mixing station based on infrared grating. Utility Model Content

[0007] The effect achieved by the above components is: by setting up a protective structure, when the infrared grating access control of the aggregate silo of the mixing station stops working, the protective cover can block the infrared grating access control to prevent the infrared grating access control from being damaged by direct impact, thereby extending the service life of the infrared grating access control.

[0008] Preferably, the arc surface of the support rod is sleeved with a spring, and two ends of the spring are fixedly connected to the slide plate and the support rod respectively.

[0009] The effect achieved by the above components is that the spring can make the two protective covers contact closely by virtue of its own elastic force.

[0010] Preferably, an auxiliary plate is fixedly connected to the inner wall of the protective cover.

[0011] The effect achieved by the above components is that when the infrared grating access control squeezes the auxiliary plate, the two auxiliary plates will respectively drive the two protective covers to move away from each other.

[0012] Preferably, a telescopic rod is fixedly connected to the inner wall of the movable frame, and one end of the telescopic rod is fixedly connected to the infrared grating access control.

[0013] The effect achieved by the above components is that the telescopic rod can support the infrared grating access control, thereby preventing the infrared grating access control from bending the output end of the electric push rod.

[0014] Preferably, a limiting structure is provided on the surface of the movable frame, and the limiting structure comprises a rectangular plate, the rectangular plate is fixedly connected to the movable frame, a screw rod is threadedly connected to the inner thread of the rectangular plate, and one end of the screw rod is rotatably connected to a pressure plate.

[0015] The effect achieved by the above components is: by setting a limit structure, the position of the infrared grating access control can be limited to any height within the installation frame, so that the height of the infrared grating access control can be adjusted according to needs, thereby ensuring that the infrared grating access control can work normally and improving the practicality of the infrared grating access control.

[0016] Preferably, one end of the screw rod is snap-connected with an elliptical block, and a rotating plate is fixedly connected to the surface of the elliptical block.

[0017] The effect achieved by the above components is: the elliptical block is pulled out from the screw rod, thereby preventing the rotating plate from being accidentally hit and causing the pressure plate to loosen.

[0018] Preferably, a plurality of cone blocks are fixedly connected to the surface of the pressure plate.

[0019] The effect achieved by the above components is that the movement of the pressing plate causes the cone block to abut against the inner wall of the installation frame, and the cone block increases the friction between the pressing plate and the installation frame.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] 1. The utility model provides a protective structure.

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-5The utility model provides a technical solution: an access control device for aggregate silo of a mixing station based on infrared grating, comprising two warehouse walls 1 and an infrared grating access control 2, a mounting frame 3 is fixedly connected to the surface of the warehouse wall 1, a protective structure 4 is provided on the inner wall of the mounting frame 3, and a limiting structure 5 is provided on the surface of a movable frame 41.

[0031] The specific settings and functions of the protective structure 4 and the limiting structure 5 are described in detail below.

[0032] like Figure 2 and Figure 3 as well as Figure 4 As shown, the protective structure 4 includes a moving frame 41, the moving frame 41 is slidably connected to the inner wall of the installation frame 3, the inner wall of the moving frame 41 is fixedly connected to an electric push rod 42, the output end of the electric push rod 42 is fixedly connected to the infrared grating access control 2, the surface of the moving frame 41 is fixedly connected to a fixed block 43, the fixed block 43 is fixedly connected to a support rod 44, the arc surface of the support rod 44 is slidably connected to a slide plate 45, the surface of the slide plate 45 is fixedly connected to a protective cover 46, the arc surface of the support rod 44 is sleeved with a spring 47, and the two ends of the spring 47 are respectively connected to the slide plate 45 and the support rod 44 Fixedly connected, the spring 47 can make the two protective covers 46 in close contact with each other by virtue of its own elastic force, the inner wall of the protective cover 46 is fixedly connected with an auxiliary plate 48, when the infrared grating access control 2 squeezes the auxiliary plate 48, the two auxiliary plates 48 will respectively drive the two protective covers 46 to move away from each other, and the inner wall of the movable frame 41 is fixedly connected with a telescopic rod 49, one end of the telescopic rod 49 is fixedly connected to the infrared grating access control 2, and the telescopic rod 49 can support the infrared grating access control 2, thereby preventing the infrared grating access control 2 from bending the output end of the electric push rod 42.

[0033] like Figure 3 and Figure 5 As shown, the limiting structure 5 includes a rectangular plate 51, which is fixedly connected to the movable frame 41, and a screw rod 52 is connected to the inner thread of the rectangular plate 51. One end of the screw rod 52 is rotatably connected to a pressure plate 53, and one end of the screw rod 52 is snap-connected to an elliptical block 54. The surface of the elliptical block 54 is fixedly connected to a rotating plate 55. The elliptical block 54 is pulled out of the screw rod 52 to prevent the rotating plate 55 from being accidentally touched and causing the pressure plate 53 to loosen. A plurality of cone blocks 56 are fixedly connected to the surface of the pressure plate 53. The movement of the pressure plate 53 will cause the cone blocks 56 to abut against the inner wall of the mounting frame 3, and the cone blocks 56 increase the friction between the pressure plate 53 and the mounting frame 3.

[0034] Working principle: when the infrared grating access control 2 is needed, the mounting plate is installed on the warehouse wall 1 of the aggregate bin of the mixing station, and then the electric push rod 42 is turned on. The extension of the output end of the electric push rod 42 will drive the infrared grating access control 2 to move. The movement of the infrared grating access control 2 will contact the auxiliary plate 48. At this time, the infrared grating access control 2 will squeeze the auxiliary plate 48, and the two auxiliary plates 48 will respectively drive the two protective covers 46 to move away from each other. In this process, the telescopic rod 49 can support the infrared grating access control 2, thereby preventing the infrared grating access control 2 from bending the output end of the electric push rod 42. The movement of the protective cover 46 will drive the slide plate 45 to slide along the arc surface of the support rod 44. The sliding of the slide plate 45 will compress the spring 47. When the two protective covers 46 no longer contact the infrared grating After the access control 2 causes obstruction, the infrared grating access control 2 can work normally. When the infrared grating access control 2 stops working, the output end of the control electric push rod 42 shrinks. At this time, the infrared grating access control 2 will move toward the direction close to the moving frame 41. The infrared grating access control 2 will no longer contact the protective cover 46. At this time, the spring 47 begins to shrink, and the slide plate 45 will use the elastic force of the spring 47 to make the protective cover 46 slide in the opposite direction. When the infrared grating access control 2 moves to a suitable position, the two protective covers 46 will contact each other. The protective cover 46 can block the infrared grating access control 2 to prevent the infrared grating access control 2 from being damaged by direct impact, thereby extending the service life of the infrared grating access control 2. The spring 47 can use its own elastic force to make the two protective covers 46 in close contact.

[0035] When the height of the infrared grating access control 2 needs to be adjusted, the movable frame 41 is slid along the inner wall of the installation frame 3. The movement of the movable frame 41 will drive the electric push rod 42 to move. The movement of the electric push rod 42 will drive the infrared grating access control 2 to move, thereby adjusting the height of the infrared grating access control 2. After the adjustment is completed, the handle is turned. The rotation of the handle will drive the elliptical block 54 to rotate. The rotation of the elliptical block 54 will drive the screw rod 52 to rotate. The screw rod 52 will drive the pressure plate 53 to move by means of the thread. The movement of the pressure plate 53 will cause the cone block 56 to abut against the inner wall of the installation frame 3. The cone block 56 reaches By increasing the friction between the pressure plate 53 and the mounting frame 3, the pressure plate 53 reaches the position of the limiting screw rod 52, and finally limits the position of the infrared grating access control 2. By limiting the position of the infrared grating access control 2 to any height within the mounting frame 3, the height of the infrared grating access control 2 can be conveniently adjusted as needed, thereby ensuring that the infrared grating access control 2 can work normally and improving the practicality of the infrared grating access control 2. Afterwards, the elliptical block 54 is pulled out from the screw rod 52 to prevent the rotating plate 55 from being accidentally touched and causing the pressure plate 53 to loosen.
