The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0032] like Figure 1-5 As shown, a traffic sign panel replacement structure provided in this embodiment includes a column 1, a movable seat 2, a sign frame 3 and a movable mechanism 4.
[0033] See also Figure 1 , Figure 2 and Figure 5The column 1 has an inner cavity, a lifting groove 11 extending to both ends of the top and bottom of the column 1 is provided on one side of the column 1, and a translation groove 12 is provided on the top of the other side, wherein the translation groove 12 faces one side of the road and the lifting groove 11 faces the outside of the road. A sliding rod 13 and a threaded rod 14 are symmetrically arranged in the column 1, and both the sliding rod 13 and the threaded rod 14 are parallel to the axis of the column 1. The threaded rod 14 is axially rotatably installed in the column 1 and the bottom end thereof is transmission-connected to a first motor 15. Specifically, the output shaft end of the first motor 15 is coaxially connected to the threaded rod 14, and the first motor 15 is fixedly installed at the bottom of the inner cavity of the column 1.
[0034] See also Figure 2 and Figure 4 The movable seat 2 is symmetrically provided with a sliding hole 21 for the sliding rod 13 to pass through and a threaded hole 22 for the threaded rod 14 to be screwed through. Rotating the threaded rod 14 can drive the movable seat 2 to slide up and down along the sliding rod 13. The movable seat 2 is provided with a sliding groove 23 at a position between the sliding hole 21 and the threaded hole 22.
[0035] See also Figure 1-Figure 4 The sign frame 3 is slidably installed in the sliding groove 23. Specifically, guide rails are respectively arranged on both sides of the sign frame 3, and the inner wall of the sliding groove 23 is provided with a guide groove slidably connected to the guide rail. The sign frame 3 is slid horizontally so that its two ends can be translated to the outside of the lifting groove 11 or the translation groove 12 respectively.
[0036] Preferably, limit plates 32 are respectively provided at both ends of the moving direction of the sign frame 3, and the size of the limit plates 32 is larger than the size of the sliding groove 23 but smaller than the size of the lifting groove 11 and the translation groove 12, so that the limit plates 32 at both ends of the sign frame 3 can respectively slide into the column 1 and abut against the moving seat 2 for limiting.
[0037] Furthermore, the sign frame 3 has an inner cavity, and its two side panels and the top are open. A sign panel 33 is placed in the sign frame 3, and the sign panel 33 can be quickly replaced. Only the old sign panel 33 needs to be taken out from the opening at the top of the sign frame 3 and the new sign panel 33 needs to be put in. The operation is simple and convenient, and the openings on both side panels of the sign frame can fully display the sign information. Of course, in order to prevent dust from dirtying the sign panel 33, transparent glass panels or plastic panels can be installed at the openings on both side panels of the sign frame 3.
[0038] The moving mechanism 4 is used to drive the sign frame 3 to translate in the sliding groove 23 .
[0039] like Figure 2 and Figure 3As shown, the moving mechanism 4 includes a second motor 41, a gear 42 and a rack 43. The rack 43 is arranged at the bottom of the sign frame 3. The second motor 41 is embedded in the bottom side of the sliding groove 23. The gear 42 is installed at the output end of the second motor 41 and meshes with the rack 43. By starting the second motor 41, the sign frame 3 can be driven to perform bidirectional translation under the transmission action of the gear 42 and the rack 43 to move the sign frame 3 to the desired position.
[0040] During normal use, the moving seat 2 is located at the top of the column 1, and the sign frame 3 protrudes from one side of the translation slot 12 to be located above the road, so that passing vehicles and pedestrians can view the road information. When a new traffic sign needs to be replaced due to changes in road information or aging of the old sign, the sign frame 3 is first driven by the moving mechanism 4 to translate to the outside of the lifting slot 11 to move away from the top of the road, and then the threaded rod 14 is driven to rotate by the first motor 15 to drive the moving seat 2 to move down to the ground with the sign frame 3, and the workers can replace the new traffic sign for the sign frame 3 on the ground.
[0041] The utility model utilizes the lateral translation of the sign frame 3 in the mobile seat 2 to change the position state of the sign frame 3, which is beneficial to keep the sign frame 3 away from the top of the road during the process of replacing the traffic sign, and change the replacement position to the outside of the road, so that the road is not occupied during the replacement process, ensuring the normal passage of road vehicles. By utilizing the lifting and lowering of the mobile seat 2, the sign frame 3 can be lowered to the ground, which is convenient for workers to construct on the ground, improves safety and provides convenience for construction.
[0042] like Figure 1 and Figure 2 As shown, in one embodiment, the column 1 is located at the bottom of the translation groove 12 and is provided with a first support platform 16 extending outward, which provides support for the sign frame 3 when it is located outside the translation groove 12, and the movable seat 2 is located at the bottom of the sliding groove 23 and is provided with a second support platform 24 extending outside the lifting groove 11, which provides support for the sign frame 3 when it is located outside the lifting groove 11, which is beneficial to improve the bearing capacity of the sign frame 3.
[0043] Furthermore, a plurality of support rollers 31 are evenly distributed at the bottom of the sign frame 3, and the support rollers 31 can abut against the top of the first support platform 16 or the second support platform 24, which is helpful to reduce the resistance between the sign frame 3 and the first support platform 16 or the second support platform 24 when moving.
