Description

Technical Field

[0001] This utility model relates to the field of road infrastructure technology, specifically to a rotatable and adjustable road monitoring pole. Background Technology

[0002] Currently, road monitoring systems widely adopt a fixed structure. The monitoring poles are mainly composed of uprights and crossbars fixed together by welding or flanges, forming a rigid whole. Monitoring equipment such as cameras and radar are installed at the ends of the crossbars, suspended above the road. When initial installation, angle adjustment, routine maintenance, or fault replacement is required, workers must use aerial work platforms to ascend to the top of the pole to operate it. This process necessitates the temporary closure of some lanes, disrupting smooth traffic flow. Furthermore, adjusting the monitoring angle is particularly inconvenient, often requiring technicians to perform laborious manual adjustments one by one on the pole, resulting in low efficiency. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a rotatable and adjustable road monitoring pole.

[0004] The technical solution of this utility model is as follows: A rotatable and adjustable road monitoring pole includes not only a post and a crossbar for mounting monitoring equipment, but also: The drive mechanism is mounted on the column; The support frame is rotatably connected to the upper part of the column; The bevel gear transmission pair includes a driving bevel gear and a driven bevel gear that mesh perpendicularly with each other. The driving bevel gear is driven to rotate by a drive mechanism, and the driven bevel gear is fixedly installed at one end of the crossbar near the column. The first locking mechanism can selectively lock or release the support frame from the column; The second locking mechanism can selectively lock or release the crossbar from the support frame; The crossbar is rotatably connected to the support frame; When the first locking mechanism is released and the second locking mechanism is locked, the drive mechanism can drive the support frame and the crossbar to rotate around the column axis through the bevel gear transmission pair. When the first locking mechanism is locked and the second locking mechanism is released, the drive mechanism can drive the crossbar to rotate around its own axis through the bevel gear transmission pair.

[0005] In the above scheme, the support frame is an inverted right-angled triangle, including a vertical side and a horizontal side. The vertical side is rotatably connected to the column, and the horizontal side is connected to the crossbar.

[0006] In the above scheme, there are two support frames, which are spaced apart along the axial direction of the column and jointly support the crossbar.

[0007] In the above scheme, the two support frames have the same structure and are symmetrically arranged, with the active bevel gear located between the two support frames.

[0008] In the above scheme, the driving bevel gear is located above the driven bevel gear.

[0009] In the above scheme, the diameter of the driving bevel gear is smaller than the diameter of the driven bevel gear.

[0010] In the above scheme, the first locking mechanism includes a first flange and a second flange arranged opposite to each other. The first flange is fixed to the column, and the second flange is fixed to the support frame. The first flange and the second flange are connected by fasteners to achieve locking.

[0011] In the above scheme, the second locking mechanism includes a third flange and a fourth flange arranged opposite to each other. The third flange is fixed on the support frame, and the fourth flange is fixed on the crossbar. The third flange and the fourth flange are connected by fasteners to achieve locking.

[0012] In the above scheme, the fasteners are a combination of bolts and nuts, and both the third and fourth flanges are provided with locking holes for bolts to pass through, and the locking hole on at least one flange is an arc-shaped slot.

[0013] In the above scheme, the drive mechanism is either electric or manual.

[0014] This utility model provides a rotatable and adjustable road monitoring pole. Through the coordinated operation of a set of bevel gear transmission pairs and two sets of independent locking mechanisms, the crossbar can be rotated to the roadside during installation and equipment maintenance. During angle adjustment, the crossbar can rotate independently around its own axis, avoiding road occupation and significantly reducing interference with road traffic. Moreover, by uniformly adjusting the cameras, radars, and other sensors on the crossbar, the difficulty of individual adjustment is avoided, and the efficiency of debugging is improved.

Bevel gear transmission pair; 51. Driving bevel gear; 52. Driven bevel gear; 6. First locking mechanism; 61. First flange; 62. Second flange; 7. Second locking mechanism; 71. Third flange; 72.

[0017] Example 1 like Figure 1 and Figure 2 As shown, this embodiment provides a rotatable and adjustable road monitoring pole, including a column 1, a crossbar 2, a drive mechanism 3, a support frame 4, a bevel gear transmission pair 5, a first locking mechanism 6, and a second locking mechanism 7.

[0018] The column 1 serves as the main supporting structure, fixed to the ground, with space reserved inside for pre-installed wiring. The crossbar 2 extends above the road, with an installation interface at its end for mounting surveillance equipment such as cameras and radar.

[0019] The support frame 4 is rotatably connected to the upper part of the column 1 via bearings. Preferably, the support frame 4 is in the form of an inverted right-angled triangle. Its vertical side has a first sleeve 41, which is fitted onto the column 1 and rotatably connected to it via bearings. The horizontal side of the support frame 4 has a second sleeve 42, which is fitted onto the crossbar 2 and rotatably connected to it via bearings. See details [link to details]. Figure 1 This triangular support structure can effectively transfer the bending moment of the crossbar 2 to the column 1, improving overall stability. In addition, by setting a first sleeve 41 and a second sleeve 42 of a certain length, stable support can be provided for the rotation of the support frame 4 and the crossbar 2.

[0020] A bevel gear transmission pair 5 is disposed above the support frame 4, and includes a driving bevel gear 51 and a driven bevel gear 52 that mesh perpendicularly with each other. The driving bevel gear 51 is rotatably connected to the column 1 via a bearing, rotates coaxially with the support frame 4, and is driven to rotate by a drive mechanism 3 mounted on the column 1. The driven bevel gear 52 is fixed to one end of the crossbar 2 near the column 1, and the driving bevel gear 51 and the driven bevel gear 52 always maintain a perpendicular meshing state.

[0021] In this embodiment, the driving bevel gear 51 is positioned above the driven bevel gear 52. Because the support frame 4 generates a lever effect when supporting the crossbar 2, the end of the crossbar 2 near the column 1 tends to tilt upwards, leading to uneven stress on the connected bearings. Prolonged use may cause the end of the crossbar 2 to sag or the crossbar 2 to rotate sluggishly. In this embodiment, the driving bevel gear 51, positioned above the driven bevel gear 52, can exert a downward force on the end of the crossbar 2 near the column 1, balancing the lever torque generated at the end of the crossbar 2 and ensuring smooth rotation of the crossbar 2.

[0022] To enable the two movement modes of the crossbar 2, this embodiment is equipped with two independent locking mechanisms.

[0023] The first locking mechanism 6 is located between the column 1 and the support frame 4, and adopts a flange mating form with opposite sides. That is, the first flange 61 is fixed on the column 1 and the second flange 62 is fixed on the support frame 4. The support frame 4 and the column 1 are selectively locked or released by fastener connection.

[0024] The first flange 61 is preferably located below the support frame 4, and the second flange 62 is located at the lower end of the first sleeve 41. Through the cooperation of the first flange 61 and the second flange 62, not only can the support frame 4 be locked and released, but the support effect of the support frame 4 can also be improved, thereby improving the support stability of the crossbar 2.

[0025] In this embodiment, the fasteners are a combination of bolts and nuts. The first flange 61 and / or the second flange 62 are provided with multiple locking holes to lock the support frame 4 in different positions, including at least locking the support frame 4 and the crossbar 2 in a position directly above the road or in a safe area on the side of the road.

[0026] The second locking mechanism 7 is located between the support frame 4 and the crossbar 2, and also adopts a flange structure with opposite flanges. That is, a third flange 71 is fixed on the support frame 4, and a fourth flange 72 is fixed on the crossbar 2. The crossbar 2 and the support frame 4 are selectively locked or released by fasteners. See details. Figure 2 As shown.

[0027] In addition, both the third flange 71 and the fourth flange 72 are provided with locking holes for bolts to pass through, and at least one of the third flange 71 and the fourth flange 72 has an arc-shaped slot 73 as the locking hole. This design allows the crossbar 2 to rotate freely within a limited angle range in the unlocked state, while reliably positioning it by tightening the bolts when fixation is required. The arc of the arc-shaped slot 73 is preferably 30-180 degrees.

[0028] When equipment maintenance is required, the operator first locks the second locking mechanism 7 to integrate the crossbar 2 with the support frame 4, and then releases the first locking mechanism 6. At this time, the drive mechanism 3 is activated. The rotation of the active bevel gear 51, through the reaction force of the gear pair, pushes the entire support frame 4, causing the crossbar 2 to rotate horizontally around the axis of the column 1. This moves the monitoring equipment to a safe area on the roadside for operation, completely avoiding any impact on road traffic and improving operational safety. When adjusting the monitoring angle, the operator first locks the first locking mechanism 6 to fix the support frame 4, and then releases the second locking mechanism 7. At this time, the drive mechanism 3 directly drives the crossbar 2 to rotate around its own axis through the bevel gear transmission pair 5, achieving unified adjustment of the pitch angle of the camera, radar, and other equipment on the crossbar 2. This greatly improves debugging efficiency and safety, and does not occupy the road, avoiding any impact on road traffic.

[0029] To further enhance stability, two support frames 4 can be provided, spaced apart along the axial direction of the column 1 and jointly supporting the crossbar 2. Specifically, the two support frames 4 have identical structures and are symmetrically arranged vertically relative to the crossbar 2, forming a double-support structure, with the active bevel gear 51 located between the two support frames 4. This symmetrical layout makes the force on the crossbar 2 more balanced, effectively improving its wind load resistance and load-bearing stability.

[0030] In addition, ribs are provided between the two sleeves on support frame 4 and the vertical and horizontal sides, as can be seen in [reference]. Figure 2 As shown, this improves the lateral shear resistance of the support frame 4.

[0031] The drive mechanism 3 can be located outside or inside the column 1, and includes a meshing drive gear and a drive gear ring. The drive gear is connected to the drive shaft, which is rotatably connected to the column 1. The drive gear ring is coaxially connected to the drive bevel gear 51. Depending on actual needs, the drive mechanism 3 can be selected as electric or manual, and the drive shaft is rotated directly or by transmission to drive the drive bevel gear 51 to rotate.

[0032] In this embodiment, a motor drive is used. The motor is fixedly connected inside the column 1, and its output end is connected to the drive shaft through gear transmission. The gear transmission includes multiple sets of gears to form a reduction mechanism.

[0033] In particular, the diameter of the driving bevel gear 51 is smaller than that of the driven bevel gear 52, which not only achieves speed reduction and torque increase, but also improves the adjustment accuracy when the crossbar 2 rotates.
