Description

Technical Field

[0001] This utility model relates to the field of crane radar, and in particular to a high-efficiency wide-angle human body detection radar for cranes. Background Technology

[0002] In construction, logistics loading and unloading, and large equipment installation, cranes, as core heavy-duty machinery, have always had their operational safety as a core focus of the industry. During crane operations, the lifting, lowering, rotation, and transfer of heavy objects need to cover a large area, especially the area behind the crane tower base. Due to the crane's own structure (such as the tower columns and transmission components), blind spots can easily form. This area is often used for personnel passage and auxiliary equipment parking. If the presence of a person cannot be detected in time, it can easily lead to collisions, crushing accidents, and other safety incidents, posing a serious threat to personnel safety.

[0003] To mitigate safety risks, some existing cranes are equipped with human detection radar. However, in actual operation, because these radars are fixedly installed at the rear of the crane tower base, and the tower base itself is relatively large, the detection coverage of the radar is limited, making it difficult to meet the need for comprehensive detection of the rear of the tower base. Furthermore, because blind spot detection cannot be quickly completed in advance before critical operations such as boom adjustment and rotation, the timeliness and comprehensiveness of safety protection are insufficient.

[0004] Traditional methods that rely on manual observation or the installation of detection radar in a single fixed location can no longer meet the needs of modern cranes for efficient and safe operation.

[0005] Therefore, it is necessary to provide a new, high-efficiency wide-angle human detection radar for cranes to solve the above-mentioned technical problems. Utility Model Content

[0006] To solve the above-mentioned technical problems, this utility model provides a high-efficiency wide-angle human body detection radar for cranes.

[0007] This utility model provides a high-efficiency wide-angle human body detection radar for cranes, comprising: a fixed frame, with lugs fixedly connected to both ends of the fixed frame; an adjustment seat on the fixed frame; a mounting frame fixedly connected to the adjustment seat; and a radar assembly installed in the mounting frame; a wide-angle adjustment mechanism, comprising a gear ring, with multiple connecting protrusions fixedly connected to the gear ring, all of which are fixedly connected to the fixed frame; and a gear located below the adjustment seat, the gear meshing with the gear ring.

[0008] Preferably, the plurality of connecting protrusions are arranged in an equidistant ring, the adjusting seat is provided with a mounting groove, a motor is installed and connected in the mounting groove, and the output end of the motor is fixedly connected to a gear.

[0009] Preferably, the fixed ring frame is provided with an arc-shaped through groove, the rear end of the adjusting seat is provided with a slider, the slider is slidably connected to the arc-shaped through groove, and an arc-shaped back seat is fixedly connected to the slider.

[0010] Preferably, the adjusting seat and the arc-shaped back seat are respectively located on both sides of the arc-shaped through groove.

[0011] Preferably, both the adjustment seat and the arc-shaped back seat are symmetrically provided with multiple embedded grooves, and the multiple embedded grooves are arranged symmetrically in pairs.

[0012] Preferably, each of the plurality of embedded slots is rotatably connected to a wheel axle, and each of the plurality of wheel axles is fixedly connected to a stop wheel.

[0013] Compared with related technologies, the high-efficiency wide-angle human body detection radar for cranes provided by this utility model has the following beneficial effects:

[0014] 1. This utility model uses a motor to drive a gear and a gear ring to mesh, which can automatically drive the adjustment seat to slide in an arc along the fixed ring frame in advance, thereby enabling the radar component to achieve multi-angle detection. It can fully cover the area behind and around the crane base in different directions. In actual operation, it can capture human signals within the rear detection range in real time and quickly, promptly reminding crane operators to avoid risks and effectively reducing the probability of safety accidents such as collisions and crushing caused by blind spots during crane operation.

[0015] 2. This utility model uses the guide cooperation between the slider and the arc-shaped through groove to limit the movement trajectory of the adjustment seat. Multiple symmetrically arranged abutment wheels roll close to the outer wall of the fixed ring frame, using rolling friction instead of sliding friction to significantly reduce component wear. It can also effectively balance the force on the adjustment seat during movement, avoiding shaking of the adjustment seat due to uneven force on one side. This ensures that the radar component remains stable during angle adjustment, and there will be no deviation or error in the detection signal due to shaking. This ensures the accuracy of the detection data and provides reliable signal support for the safe judgment of crane operation. Attached Figure Description

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the following: Figures 1 to 3 A high-efficiency wide-angle human body detection radar for cranes includes: a fixed frame 1, with ear seats 11 fixedly connected to both ends of the fixed frame 1, an adjustment seat 2 provided on the fixed frame 1, a mounting frame 3 fixedly connected to the adjustment seat 2, and a radar component 31 installed and connected in the mounting frame 3; a wide-angle adjustment mechanism, including a gear ring 4, with multiple connecting protrusions 41 fixedly connected to the gear ring 4, all of which are fixedly connected to the fixed frame 1, and a gear 42 provided at the lower position of the adjustment seat 2, the gear 42 meshing with the gear ring 4.

[0022] In the specific implementation process, such as Figure 1 and Figure 2 As shown, multiple connecting protrusions 41 are arranged in an equidistant ring. The adjusting seat 2 is provided with an installation groove, in which a motor 5 is installed and connected. The output end of the motor 5 is fixedly connected to the gear 42.

[0023] It should be noted that the multiple connecting protrusions 41 are arranged in an equidistant ring, which can ensure that the connection force between the gear ring 4 and the fixed ring frame 1 is uniform, thereby ensuring the stability of the meshing transmission between the gear 42 and the gear ring 4.

[0024] The mounting slot on the adjusting seat 2 is adapted to the size of the motor 5. The output end of the motor 5 drives the gear 42 to rotate. Since the gear 42 meshes with the gear ring 4 fixed on the fixed ring frame 1, the rotation of the gear 42 will be converted into the arc movement of the adjusting seat 2 along the trajectory of the gear ring 4, thereby realizing the adjustment of the angle and position of the adjusting seat 2.

[0025] refer to Figure 1 and Figure 2 As shown, the fixed frame 1 is provided with an arc-shaped through groove 6, and the rear end of the adjusting seat 2 is provided with a slider 61. The slider 61 is slidably connected to the arc-shaped through groove 6, and an arc-shaped back seat 62 is fixedly connected to the slider 61.

[0026] It should be noted that the curvature of the arc-shaped through groove 6 is consistent with the curvature of the gear ring 4, ensuring that the adjusting seat 2 can move synchronously along the trajectory of the arc-shaped through groove 6 under the meshing drive of the gear 42 and the gear ring 4, thus avoiding trajectory deviation.

[0027] The cross-sectional shape of the slider 61 matches the cross-sectional shape of the arc-shaped through groove 6, which can not only achieve smooth sliding, but also prevent the slider 61 from detaching from the arc-shaped through groove 6. At the same time, the curvature of the arc-shaped back seat 62 is adapted to the curvature of the rear outer wall of the fixed ring frame 1, providing a fitting basis for the subsequent installation and rolling of the abutment wheel 71.

[0028] refer to Figure 2 and Figure 3 As shown, the adjusting seat 2 and the arc-shaped back seat 62 are respectively located on both sides of the arc-shaped through groove 6.

[0029] It should be noted that the adjusting seat 2 and the arc-shaped back seat 62 are respectively located on both sides of the arc-shaped through groove 6, forming a structure similar to a locking mechanism. This structure can clamp the groove wall of the fixing ring frame 1 in the middle. This symmetrical distribution can balance the force on one side of the adjusting seat 2 during the movement process and prevent the adjusting seat 2 from tilting to one side due to the weight on one side.

[0030] At the same time, this arrangement also provides a basis for installing the abutment rollers 71 on both sides, so that the abutment rollers 71 can achieve rolling support from both the inner and outer sides of the arc-shaped through groove 6, further improving the stability of the adjusting seat 2.

[0031] refer to Figure 3 As shown, both the adjustment seat 2 and the arc-shaped back seat 62 are symmetrically provided with multiple embedded grooves, and the multiple embedded grooves are arranged symmetrically in pairs.

[0032] It should be noted that the embedded grooves are arranged symmetrically in pairs, and the embedded grooves on the adjusting seat 2 correspond one-to-one with the embedded grooves on the arc-shaped back seat 62, ensuring that the subsequent installed abutment wheel 71 can form symmetrical support points on both sides of the arc-shaped through groove 6.

[0033] refer to Figure 2 and Figure 3 As shown, multiple embedded slots are rotatably connected to axles 7, and multiple axles 7 are fixedly connected to abutment wheels 71.

[0034] It should be noted that the rotation of the abutment wheel 71 can further reduce the rolling friction coefficient between the slider 61 and the inner wall of the arc-shaped through groove 6, making the arc-shaped sliding of the adjustment seat 2 smoother. In addition, the rolling synchronization of multiple abutment wheels 71 is good, which can jointly distribute the weight pressure of the adjustment seat 2 and the radar component 31.

[0035] The working principle of the high-efficiency wide-angle human body detection radar for cranes provided by this utility model is as follows: First, the entire radar device is stably fixed at the rear end of the crane tower base by means of the lugs 11 at both ends of the fixed frame 1.

[0036] When it is necessary to adjust the position of the boom, it is necessary to detect different positions such as the rear side of the tower base in advance. Start the motor 5 on the adjusting seat 2, so that its output end drives the gear 42 to rotate. Since the gear 42 meshes with the gear ring 4 fixed on the fixed frame 1, the rotation of the gear 42 will be converted into the arc movement of the adjusting seat 2 along the trajectory of the gear ring 4, thereby realizing the adjustment of the angle and position of the adjusting seat 2, so as to achieve comprehensive detection of the rear side of the tower base.

[0037] During the movement of the adjusting seat 2, the slider 61 at its rear end is embedded in the arc-shaped through groove 6 of the fixed ring frame 1 and slides along the groove, providing a locking guide for the arc-shaped movement of the adjusting seat 2. At the same time, the adjusting seat 2 and the arc-shaped back seat 62 are located on both sides of the arc-shaped through groove 6. The wheel axle 7 embedded in the groove drives the abutment wheel 71 to roll tightly against the inner wall of the arc-shaped through groove 6. The multiple symmetrically arranged abutment wheels 71 can disperse the pressure when the adjusting seat 2 moves and reduce sliding friction. This not only ensures the smoothness of the arc-shaped sliding of the adjusting seat 2, but also further improves the stability during the movement process, ensuring that the radar component 31 remains stable during angle adjustment and does not affect the detection accuracy.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
