Description

Technical Field

[0001] The present invention relates to the technical field of speed limit marking occlusion on highways, and particularly relates to a traffic sign occlusion device. Background Art

[0002] During highway pavement construction, it is necessary to temporarily limit the vehicle driving speed, and it is required to occlude the traffic speed signs on the traffic gantry of a certain lane on the highway with temporary speed limit signs. Currently, installing temporary speed limit signs manually has the problem of low efficiency. Summary of the Invention

[0003] The purpose of the present invention is to provide a traffic sign occlusion device to solve at least one of the above problems existing in the prior art.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A traffic sign occlusion device includes a walking mechanism, a lifting jaw assembly, and a hanging frame assembly. The walking mechanism includes a walking frame and a walking drive mechanism. A plurality of left floating wheel sets and right floating wheel sets are respectively provided on the left frame and the right frame of the walking frame. The walking drive mechanism drives the left floating wheel sets and the right floating wheel sets to walk. The left floating wheel sets and the right floating wheel sets include a wheel frame, a roller, and an arc-shaped anti-collision block. The roller is installed on the wheel frame. The walking drive mechanism drives the roller to walk along a steel pipe track through a transmission component. The arc-shaped anti-collision block is installed inside the wheel frame. The roller is a concave roller, and the concave roller has an arc-shaped concave surface matching the outer shape of the steel pipe track. The lowest point of the arc edge of the arc-shaped anti-collision block is lower than the upper concave endpoint of the arc-shaped concave surface.

[0006] A fixed anti-deviation wheel set is provided on the left frame, and the fixed anti-deviation wheel set is located outside the steel pipe track. A lifting anti-deviation wheel set is provided on the left frame and the right frame, and the lifting anti-deviation wheel set is located inside the steel pipe track. A plurality of the lifting jaw assemblies are arranged at intervals along the left frame. The hanging frame assembly includes a fixed frame and an adjusting frame. The fixed frame is fixedly installed on the walking frame. The adjusting frame is located in front of the fixed frame, and a temporary speed limit sign board is provided at the lower end of the adjusting frame.

[0007] In this technical solution, speed limit signs are provided above different lanes on the traffic gantry of the highway. Since the traveling mechanism includes a traveling frame and a traveling drive mechanism, the traveling drive mechanism drives the rollers to travel along the steel pipe track through a transmission component. The hanging frame assembly includes a fixed frame and an adjustment frame. The fixed frame is fixedly installed on the traveling frame, and the adjustment frame is located in front of the fixed frame. A temporary speed limit sign is provided at the lower end of the adjustment frame. The movement of the hanging frame assembly is driven by the traveling of the traveling mechanism, so that the position of the temporary speed limit sign can be adjusted. Thus, the temporary speed limit sign can be moved in front of the corresponding traffic speed sign as needed to block the traffic speed sign, eliminating the need for manual high-altitude operations and improving the installation efficiency. Since there may be obstacles such as crossbeams or clamps between the two steel pipe tracks on the traffic gantry, these obstacles will affect the normal traveling of the traveling mechanism. Through the setting of the left floating wheel group and the right floating wheel group, the left floating wheel group and the right floating wheel group include a wheel frame, rollers and arc-shaped anti-collision blocks. The rollers are installed on the wheel frame, and the traveling drive mechanism drives the rollers to travel along the steel pipe track through a transmission component. The rollers are concave rollers, and the concave rollers have an arc-shaped concave surface matching the shape of the steel pipe track. The concave rollers can ensure better fitting with the steel pipe track during traveling. Since the arc-shaped anti-collision blocks are installed inside the wheel frame, the lowest point of the arc-shaped edge of the arc-shaped anti-collision block is lower than the upper concave endpoint of the arc-shaped concave surface. During the traveling of the traveling mechanism, the arc-shaped edge of the arc-shaped anti-collision block first collides with the obstacle and can directly slide over the obstacle through the arc-shaped edge. And during this process, the overall lifting of the traveling frame is realized, avoiding the influence of the obstacle on the rollers, so that the traveling mechanism can travel along the steel pipe track in the presence of obstacles. Since a fixed anti-deviation wheel group is provided on the left frame and is located outside the steel pipe track, and a lifting anti-deviation wheel group is provided on the left frame and the right frame and is located inside the steel pipe track, the fixed anti-deviation wheel group and the lifting anti-deviation wheel group can ensure the stability of the traveling mechanism when traveling on the gantry. At the same time, the lifting anti-deviation wheel group can perform a lifting action during traveling to avoid collision with the crossbeam between the two steel pipe tracks. A plurality of lifting jaw assemblies are provided at intervals along the left frame. The lifting jaw assemblies have a lifting function, can avoid collision with the crossbeam between the two steel pipe tracks, and at the same time, can clamp the steel pipe track after the traveling mechanism reaches the position, ensuring the stability of the final installation position.

[0008] In summary, this device can automatically transport the temporary speed limit sign to the front of the traffic speed sign that needs to be blocked. The traveling mechanism travels along the steel pipe track of the traffic gantry. After reaching the position, the position is fixed by the lifting jaw assembly, and the traffic speed sign is blocked by the temporary speed limit sign at the lower end of the adjustment frame, thus solving the problem of low installation efficiency of manually installing temporary speed limit signs.

[0009] Furthermore, the height position of the adjusting frame relative to the fixed frame is adjustable and can be correspondingly adjusted according to the height of the traffic speed sign to be blocked specifically.

[0010] Furthermore, to facilitate the installation of the lifting jaw assembly and the control of the jaw lifting movement, the lifting jaw assembly includes a fixed seat, a first lifting rod, and a jaw assembly. The fixed seat is arranged on the left frame. The first lifting rod is in vertical sliding fit with the fixed seat. The lower end of the first lifting rod is fixedly connected to the jaw assembly. The first lifting rod is driven to lift by a jaw lifting driving device.

[0011] Furthermore, to automatically control the clamping movement of the jaws, the jaw assembly includes a fixing plate, a left jaw, and a right jaw. The fixing plate is fixedly connected to the first lifting rod. A connecting seat is provided on the fixing plate. A second lifting rod is vertically slidably connected to the connecting seat. The lower end of the second lifting rod is rotatably connected to the left jaw and the right jaw. The second lifting rod is driven to lift by a jaw driving device, thereby driving the left jaw and the right jaw to clamp the steel pipe track.

[0012] Furthermore, to automatically control the lifting of the anti-deviation wheels, the lifting anti-deviation wheel group includes a mounting seat, a third lifting rod, and anti-deviation wheels. The anti-deviation wheels are rotatably mounted at the lower end of the third lifting rod. The third lifting rod is in vertical sliding connection with the mounting seat. The third lifting rod is driven to lift by an anti-deviation lifting driving device.

[0013] Furthermore, to improve the convenience of adjusting the height position between the adjusting frame and the fixed frame bracket, a horizontal extension frame is provided on the fixed frame in the direction towards the adjusting frame. A vertical sleeve is provided on the horizontal extension frame. The two vertical rods of the adjusting frame slide vertically along the vertical sleeve. A vertical locking member is provided between the vertical sleeve and the vertical rod.

[0014] Furthermore, to be able to automatically adjust the gap between the fixed frame and the adjusting frame, the horizontal extension frame includes two horizontal extension rods. A horizontal sleeve is horizontally slidably connected to the horizontal extension rods. The horizontal sleeve is fixedly connected to the vertical sleeve. A spacing adjustment device is provided on the fixed frame. The spacing adjustment device drives the adjusting frame to move horizontally along the horizontal extension rods.

[0015] Furthermore, to facilitate the stable installation of the adjusting frame on the fixed frame, the horizontal extension frame includes two connecting pipes. The connecting pipes are sleeved and fixed on the two vertical rods of the fixed frame. A first cross bar is provided between the connecting pipes. The horizontal extension rod is fixedly connected to the corresponding connecting pipe. A second cross bar is provided between the horizontal sleeves.

[0016] Further, in order to provide speed limit prompts through the temporary speed limit signboards, speed limit signs are provided on the temporary speed limit signboards.

[0017] Further, in order to automatically achieve obstacle avoidance and lifting actions according to obstacles, an obstacle detection device is provided on the walking frame. The obstacle detection device is electrically connected to the controller, and the controller is electrically connected to the jaw lifting drive device and the anti-deviation lifting drive device.

[0018] The beneficial effects of the present invention are as follows: In this technical solution, different speed limit signs are provided above different lanes on the traffic gantry of the highway. Since the walking mechanism includes a walking frame and a walking drive mechanism, the walking drive mechanism drives the rollers to move along the steel pipe track through a transmission component. The hanging frame assembly includes a fixed frame and an adjustable frame. The fixed frame is fixedly installed on the walking frame, and the adjustable frame is located in front of the fixed frame. A temporary speed limit signboard is provided at the lower end of the adjustable frame. The movement of the hanging frame assembly is driven by the walking of the walking mechanism, so that the position of the temporary speed limit signboard can be adjusted. Thus, the temporary speed limit signboard can be moved in front of the corresponding traffic speed signboard as needed to block the traffic speed signboard, eliminating the need for manual high-altitude operations and improving the installation efficiency. Since there will be obstacles such as crossbeams or clamps between the two steel pipe tracks on the traffic gantry, the obstacles will affect the normal walking of the walking mechanism. Through the arrangement of the left floating wheel set and the right floating wheel set, the left floating wheel set and the right floating wheel set include a wheel frame, rollers and arc-shaped anti-collision blocks. The rollers are installed on the wheel frame. The walking drive mechanism drives the rollers to move along the steel pipe track through a transmission component. The rollers are concave rollers, and the concave rollers have an arc-shaped concave surface matching the outer shape of the steel pipe track. The concave rollers can ensure better fitting with the steel pipe track during the walking process. Since the arc-shaped anti-collision blocks are installed on the inner side of the wheel frame, the lowest point of the arc-shaped edge of the arc-shaped anti-collision block is lower than the upper concave endpoint of the arc-shaped concave surface. During the walking process of the walking mechanism, the arc-shaped edge of the arc-shaped anti-collision block first collides with the obstacle and can directly slide over the obstacle through the arc-shaped edge. And during this process, the overall lifting of the walking frame is achieved, avoiding the influence of the obstacle on the rollers, so that the walking mechanism can move along the steel pipe track in the presence of obstacles. Since a fixed anti-deviation wheel set is provided on the left frame, the fixed anti-deviation wheel set is located outside the steel pipe track, and a lifting anti-deviation wheel set is provided on the left frame and the right frame. The lifting anti-deviation wheel set is located inside the steel pipe track. The fixed anti-deviation wheel set and the lifting anti-deviation wheel set can ensure the stability of the walking mechanism when walking on the gantry. At the same time, the lifting anti-deviation wheel set can perform lifting actions during the walking process to avoid collision with the crossbeam between the two steel pipe tracks. A plurality of lifting jaw assemblies are provided at intervals along the left frame. The lifting jaw assemblies have a lifting function, which can avoid collision with the crossbeam between the two steel pipe tracks. At the same time, after the walking mechanism reaches the position, it can clamp the steel pipe track to ensure the stability of the final installation position.

[0019] In summary, this device can automatically transport the temporary speed limit signboard in front of the traffic speed signboard to be blocked. The traveling mechanism travels along the steel pipe track of the traffic gantry. After reaching the designated position, it is fixed by the lifting jaw assembly, and the traffic speed signboard is blocked by the temporary speed limit signboard at the lower end of the adjusting frame, thus solving the problem of low installation efficiency of manually installing temporary speed limit signs.

[0026] Embodiment 1:

[0027] As Figures 1 - 4As shown in the figure, this embodiment provides a traffic sign occlusion device, which includes a walking mechanism, a lifting jaw assembly 11 and a hanging frame assembly. The walking mechanism includes a walking frame 1 and a walking drive mechanism 2. A plurality of left floating wheel sets 3 and right floating wheel sets 4 are respectively provided on the left frame 1.1 and the right frame 1.2 of the walking frame 1. The walking drive mechanism 2 drives the left floating wheel sets 3 and the right floating wheel sets 4 to walk. The left floating wheel sets 3 and the right floating wheel sets 4 include a wheel frame 5, a roller 6 and an arc-shaped anti-collision block 7. The roller 6 is installed on the wheel frame 5. The walking drive mechanism 2 drives the roller 6 to walk along the steel pipe track 8 through a transmission component. The arc-shaped anti-collision block 7 is installed inside the wheel frame 5. The roller 6 is a concave roller, and the concave roller has an arc-shaped concave surface 6.1 that matches the outer shape of the steel pipe track 8. The lowest point of the arc edge of the arc-shaped anti-collision block 7 is lower than the upper concave endpoint of the arc-shaped concave surface 6.1.

[0028] A fixed anti-deviation wheel set 9 is provided on the left frame 1.1. The fixed anti-deviation wheel set 9 is located outside the steel pipe track 8. A lifting anti-deviation wheel set 10 is provided on the left frame 1.1 and the right frame 1.2. The lifting anti-deviation wheel set 10 is located inside the steel pipe track 8. A plurality of lifting jaw assemblies 11 are arranged at intervals along the left frame 1.1. The hanging frame assembly includes a fixed frame 12 and an adjusting frame 13. The fixed frame 12 is fixedly installed on the walking frame 1. The adjusting frame 13 is located in front of the fixed frame 12. A temporary speed limit sign 14 is provided at the lower end of the adjusting frame 13.

[0029] In this technical solution, speed limit signs are provided above different lanes on the traffic gantry 36 of the highway. Since the traveling mechanism includes a traveling frame 1 and a traveling drive mechanism 2, the traveling drive mechanism 2 drives the rollers 6 to travel along the steel pipe track 8 through a transmission assembly. The hanging frame assembly includes a fixed frame 12 and an adjustment frame 13. The fixed frame 12 is fixedly installed on the traveling frame 1, and the adjustment frame 13 is located in front of the fixed frame 12. A temporary speed limit sign 14 is provided at the lower end of the adjustment frame 13. By driving the hanging frame assembly to move through the traveling of the traveling mechanism 1, the position of the temporary speed limit sign 14 can be adjusted, so that the temporary speed limit sign 14 can be moved in front of the corresponding traffic speed sign 37 as needed to block the traffic speed sign 37, without the need for manual high-altitude operation and with higher installation efficiency. Since there will be obstacles 38 such as crossbeams or clamps between the two steel pipe tracks 8 on the traffic gantry 36, the obstacles 38 will affect the normal traveling of the traveling mechanism. Through the setting of the left floating wheel set 3 and the right floating wheel set 4, the left floating wheel set 3 and the right floating wheel set 4 include a wheel frame 5, rollers 6 and arc-shaped anti-collision blocks 7. The rollers 6 are installed on the wheel frame 5, and the traveling drive mechanism 2 drives the rollers 6 to travel along the steel pipe track 8 through a transmission assembly. The rollers 6 are concave rollers, and the concave rollers have an arc-shaped concave surface 6.1 that matches the outer shape of the steel pipe track 8. The concave rollers can ensure better fitting with the steel pipe track 8 during the traveling process. Since the arc-shaped anti-collision blocks 7 are installed inside the wheel frame 5, the lowest point of the arc-shaped edge of the arc-shaped anti-collision block 7 is lower than the upper concave endpoint of the arc-shaped concave surface 6.1. During the traveling process of the traveling mechanism, the arc-shaped edge of the arc-shaped anti-collision block 7 first collides with the obstacle 38 and can directly slide over the obstacle 38 through the arc-shaped edge, and the overall lifting of the traveling frame 1 is achieved during this process, avoiding the influence of the obstacle 38 on the rollers 6, so that the traveling mechanism can travel along the steel pipe track 8 in the presence of the obstacle 38. Since a fixed anti-deviation wheel set 9 is provided on the left frame 1.1, the fixed anti-deviation wheel set 9 is located outside the steel pipe track 8, and a lifting anti-deviation wheel set 10 is provided on the left frame 1.1 and the right frame 1.2, and the lifting anti-deviation wheel set 10 is located inside the steel pipe track 8. The fixed anti-deviation wheel set 9 and the lifting anti-deviation wheel set 10 can ensure the stability of the traveling mechanism when traveling on the gantry 36. At the same time, the lifting anti-deviation wheel set 10 can perform a lifting action during the traveling process to avoid collision with the crossbeam between the two steel pipe tracks 8. A plurality of lifting jaw assemblies 11 are provided at intervals along the left frame 1.1. The lifting jaw assemblies 11 have a lifting function, can avoid collision with the crossbeam between the two steel pipe tracks 8, and at the same time, can clamp the steel pipe track 8 after the traveling mechanism travels to the position, ensuring the stability of the final installation position.

[0030] In summary, the present device can automatically convey the temporary speed limit sign 14 in front of the traffic speed sign 37 to be blocked. The traveling mechanism travels along the steel pipe track 8 of the traffic gantry 36. After reaching the designated position, it fixes the position through the lifting jaw assembly 11, and blocks the traffic speed sign 37 with the temporary speed limit sign 14 at the lower end of the adjusting frame 13, thus solving the problem of low installation efficiency of manually installing temporary speed limit signs.

[0045] In order to improve the convenience of adjusting the height position between the adjusting frame 13 and the fixing frame 12, a horizontal extension frame 26 is provided on the fixing frame 12 in the direction towards the adjusting frame 13. A vertical sleeve 27 is provided on the horizontal extension frame 26. Two vertical rods 28 of the adjusting frame 13 slide vertically along the vertical sleeve 27, and a vertical locking member (not shown in the figure) is provided between the vertical sleeve 27 and the vertical rod 28.

[0046] Example 7:

The horizontal extension rod 29 is fixedly connected to the corresponding connecting pipe 32, and a second cross bar 35 is provided between the horizontal sleeves 30.

[0052] Example 9:

[0053] This embodiment is optimized on the basis of the above-mentioned Embodiment 1.

[0054] In order to give a speed limit reminder through the temporary speed limit sign 14, a speed limit sign is provided on the temporary speed limit sign 14.

[0055] Example 10:

[0056] This embodiment is optimized based on the above-mentioned Embodiment 1.

[0057] In order to automatically achieve obstacle avoidance and lifting actions according to obstacles, an obstacle detection device (not shown in the figure) is provided on the walking frame 1. The obstacle detection device (not shown in the figure) is electrically connected to a controller (not shown in the figure), and the controller (not shown in the figure) is electrically connected to a jaw lifting drive device (not shown in the figure) and an anti-deviation lifting drive device (not shown in the figure).

[0058] It should be noted that both the jaw lifting drive device and the anti-deviation lifting drive device in this technical solution can be driven by electric lifting devices in the prior art, such as electric push rods, etc., as long as the mechanism capable of achieving lifting control can be used.

[0059] When the obstacle detection device detects an obstacle, the controller controls the jaw lifting drive device and the anti-deviation lifting drive device to start, and lifts the jaw assembly 17 and the anti-deviation wheel 25 to a set height, so as to facilitate walking around the obstacle 38. When the walking mechanism reaches the position, the jaw drive device starts to clamp the steel pipe.

[0060] It should be noted that during transportation, the hanging frame assembly and the walking mechanism are disassembled and transported. After arriving at the site, a cantilever crane is installed on the column of the gantry 36, the hanging frame assembly and the walking mechanism are combined, and the height of the temporary speed limit sign 14 is adjusted. Then, the traffic sign shielding device is hoisted onto the gantry 36 so that the traveling roller 6 is accurately located on the steel pipe track 8 of the gantry 36. The walking drive mechanism 2 is started, and the roller 6 rotates to drive the walking mechanism to walk on the steel pipe track 8. When encountering an obstacle 38, the arc-shaped anti-collision block 7 can slide over the obstacle 38 and lift the walking mechanism. After crossing the obstacle, the walking mechanism descends, and the roller 6 returns to the steel pipe track 8 and walks normally. At the same time, when encountering an obstacle 38, the anti-deviation lifting drive device lifts the anti-deviation wheel 25 to an appropriate height, and the jaw lifting drive device lifts the jaw assembly 17 to an appropriate height to avoid collision with the obstacle during walking.

[0061] It should be noted that after the device travels to the set position, the obstacle detection device will detect whether there is an obstacle affecting the clamping of the jaw. If the clamping requirement is met, the jaw drive device starts to clamp and fix the steel pipe track 8. Finally, the spacing adjustment device 31 drives the adjustment frame 13 to move horizontally along the horizontal extension rod 29 to adjust the spacing between the temporary speed limit sign 14 and the traffic speed sign 37. The spacing adjustment device 31 can be a motor driving a lead screw to rotate, so as to control the spacing adjustment.

[0062] This device is equipped with an operation terminal, which is electrically connected to the controller. During specific operations, personnel operate and control it on the ground. During the operation of the device, the automatic wire rewinding device needs to be manually adjusted to ensure that the power cord has an appropriate sag to prevent it from being too tight or too loose.

[0063] This device can remotely control the walking mechanism on the ground to move along the steel pipe track 8, facilitating the movement of the temporary speed limit sign 14 at high altitude. Thus, the temporary speed limit sign 14 can be moved in front of the traffic speed sign 37 to achieve occlusion, avoiding the danger of manual high-altitude operations. The entire device can be reused.

[0064] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
