Existing anti - collision measures mostly rely on manual monitoring or simple mechanical limit devices, making it difficult to achieve precise anti - collision effects. Therefore, a more intelligent and efficient anti - collision protection device is needed. Summary of the Utility Model

Description of the Drawings

[0014] Figure 1 It is a structural diagram of the present utility model.

[0015] Figure 2 It is a structural diagram of the infrared emitter. Detailed Embodiment

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative work shall fall within the protection scope of the present utility model.

[0017] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0018] As Figure 1 shown, an upper and lower layer crane anti-collision protection device based on infrared anti-collision includes an upper traveling mechanism 1 and a lower traveling mechanism 2.

[0019] On both sides of the top of the upper traveling mechanism 1, an upper infrared transmitter 7 and an upper infrared receiver 8 are respectively arranged, and at least one first upper infrared anti-collision mounting plate 3 is arranged between the upper infrared transmitter and the upper infrared receiver; at least one first lower infrared anti-collision mounting plate 4 is arranged at the bottom of the upper traveling mechanism 1;

[0020] On both sides of the top of the lower traveling mechanism 2, a lower infrared transmitter 9 and a lower infrared receiver 10 are respectively arranged, and at least one second upper infrared anti-collision mounting plate 5 is arranged between the lower infrared transmitter and the lower infrared receiver; at least one second lower infrared anti-collision mounting plate 6 is arranged at the bottom of the lower traveling mechanism 2.

[0021] It should be noted that the first upper infrared anti-collision mounting plate 3 and the second upper infrared anti-collision mounting plate 5 have the same height; the first lower infrared anti-collision mounting plate 4 and the second lower infrared anti-collision mounting plate 6 have the same height; and the height of the first lower infrared anti-collision mounting plate 4 is higher than that of the second upper infrared anti-collision mounting plate 5, so as to ensure that the lower traveling mechanism 2 can maintain a certain safety distance from the upper traveling mechanism 1 and can cover all possible collision areas between the cranes.

[0022] Moreover, the upper infrared receiver 8 and the lower infrared receiver 10 send the collected data to the control system, and the control system is also connected with a distance detection circuit, a braking device and an alarm device.

[0023] The upper infrared transmitter 7 and the lower infrared transmitter 9 both include a lens barrel 11. At the bottom of the lens barrel 11, a high-power infrared emission tube 12 is arranged. On the output optical path of the high-power infrared emission tube 12, a concave lens 13 and a convex lens 14 are arranged in sequence from near to far. In this way, it is ensured that the infrared rays are emitted from the lens in the form of parallel light, the light is as concentrated as possible, and the intensity is as large as possible. The concave lens 13 and the convex lens 14 are both installed on the lens barrel 11; and the high-power infrared emission tube 12 is connected with a drive circuit, and the drive circuit is connected with the control system; encoders are arranged on the upper traveling mechanism 1 and the lower traveling mechanism 2, and the encoders are connected with the control system. In this way, when the encoder calculates that the upper traveling mechanism 1 or the lower traveling mechanism 2 travels to a specific position, the control system sends a signal to the drive circuit, and the drive circuit controls the high-power infrared emission tube 12 to work, and the infrared detection is turned on. In this way, the present invention avoids the disadvantage of wasting resources due to the infrared always working.

[0024] Among them, the distance detection circuit is used to receive the signal of the infrared sensor unit and calculate the distance from the crane. The distance detection circuit adopts a high-precision analog or digital circuit to ensure that the infrared signal can be accurately measured and processed.

[0025] The control system uses a microprocessor or a dedicated chip to receive the signals from the distance detection circuit and make judgments and controls based on the preset safety distance threshold.

[0026] Braking device: When the control system detects that the distance between the cranes is less than the safety distance threshold, the braking device is activated for emergency braking. The braking device adopts a hydraulic or electromagnetic braking system, which can quickly and effectively stop the movement of the crane.

[0027] Alarm device: An alarm signal is sent out simultaneously with or before the emergency braking to remind the operator to pay attention. The alarm device uses sound or light signals to ensure that the operator can promptly detect the emergency situation.

[0028] The above are only the preferred embodiments of the present invention. It should be noted that for those skilled in the art, without departing from the overall concept of the present invention, several changes and improvements can still be made, and these should also be regarded as the protection scope of the present invention.
