Description

Technical Field

[0001] The utility model relates to the technical field of road height limiting devices, in particular to a road and bridge traffic height limiting device. Background Art

[0002] Existing road height limiters typically use a horizontal height limiter installed above the road. When a vehicle's height exceeds the limiter, it will be blocked by the height limiter when it reaches the limiter, thereby restricting the passage of vehicles that exceed the permitted height for vehicles on the road. A warning sign is usually placed on the height limiter to remind drivers of the height limit.

[0003] Although the existing technology can easily limit the height, it is impossible to adjust the height limit during actual use. In some special situations, when ultra-high passage is temporarily required and cannot be passed, it needs to be disassembled and adjusted, which is extremely inconvenient. In addition, the support of general height limit poles is relatively single and the stability is poor.

[0004] Therefore, in response to the above problems, a road and bridge traffic height limit device is proposed to solve the above problems. Utility Model Content

The output end of the power part 7 is connected to the worm 8 through a coupling. The length direction of the worm 8 is consistent with the length direction of the beam 1. The worm 8 passes through the beam 1 and the sliding sleeve 2, and the end of the worm 8 away from the power part 7 is connected to the turbine transmission to drive the turbine to rotate. The turbine is located in the sliding sleeve 2, and the axis of the turbine is parallel to the length direction of the sliding sleeve 2. The turbine is coaxially arranged on the outside of the threaded sleeve 5 and can drive the threaded sleeve 5 to rotate. The top end of the threaded sleeve 5 is rotatably arranged at the top of the inner side of the sliding sleeve 2. The bottom end of the threaded sleeve 5 is threadedly connected to the threaded column 4, and the threaded column 4 is arranged on the support tube 3. By starting the dual-axis motor, the dual-axis motor drives the worm 8 to rotate, the worm 8 drives the worm wheel 6 to rotate, the worm wheel 6 drives the threaded sleeve 5 to rotate, the threaded column 4 is fixed above the support tube 3, and the threaded sleeve 5 and the threaded column 4 are matched to make the sliding sleeve 2 slide relative to the support tube 3, thereby changing the height of the beam 1, thereby improving the practicality and efficiency of the device.

[0029] In this embodiment, a fixing plate 9 is provided at the bottom end of the support tube 3. The fixing plate 9 is provided in contact with the ground. A plurality of fixing holes are provided on the fixing plate 9. Connectors are provided in the fixing holes.

[0030] In this embodiment, two groups of support components are symmetrically arranged on the outer wall of the support tube 3 along the length direction of the road bridge, including an extension sleeve 12. The extension sleeve 12 is tilted relative to the support tube 3. One end of the extension sleeve 12 is hingedly set on the support tube 3, and the other end of the extension sleeve 12 is sleeved on the extension rod 11. The extension rod 11 can slide in the extension sleeve 12 to change the overall support length of the extension sleeve 12 and the extension rod 11, thereby changing the support angle. When installed on the road surface, different angles can be changed for support as needed, making the support more stable. A fixing plate 2 10 is movably set at one end of the extension rod 11 away from the extension sleeve 12, and a fixing hole is opened on the fixing plate 2 10. A connecting piece is set in the fixing hole. The connecting piece is selected from anchor bolts or expansion bolts for connecting to the ground, which improves the safety of the device.

[0033] In this embodiment, one side of the movable sleeve 16 is threadedly connected to a hand bolt 17, which passes through the movable sleeve 16 and contacts the crossbeam 1, and is used to fix the position of the movable sleeve 16. By tightening the hand bolt 17 against the crossbeam 1, the position of the movable sleeve 16 can be temporarily fixed. By loosening the hand bolt 17, the position of the movable sleeve 16 on the crossbeam 1 can be adjusted. When installed in a lane such as a two-way lane, it can be adjusted according to the position of the driver, making it easier for the driver to notice the identification plate 15, thereby improving the practicality of the device.

[0034] In this embodiment, a control assembly is also included, including a power supply and a control switch, which is connected to the power member 7 to control the raising or lowering of the beam 1, thereby improving the efficiency of the device.

[0035] Working principle: First, the entire device is placed on the road surface through the support tube 3 so that the crossbeam 1 spans the road surface, and the support tube 3 is fixedly connected to the ground through the fixing plate 1 9 and the connecting piece, and then the extension rod 11 and the extension sleeve 12 are pulled and extended, and the fixing bolts 13 are inserted into the round holes and the adjustment holes 14, and fixed with the fixing nuts, so that the fixing plate 2 10 is in contact with the ground and fixed to the ground through the connecting piece to complete the installation of the device; when the height of the crossbeam 1 needs to be adjusted, the power part 7 can be started, and the worm gear 6 can be driven to rotate by the worm 8, and the worm gear 6 drives the threaded sleeve 5 to rotate.
