Abstract
Description
Technical Field
[0001] The present application relates to the technical field of road height limit frames, and in particular to a municipal road height limit frame. Background Art
[0002] There are fixed height limit frames, which are further divided into fixed integrated height limit frames and fixed indestructible height limit frames; fixed integrated height limit frames are disposable, non-adjustable height limit frames, which rely on the frame itself to intercept vehicles; fixed indestructible height limit frames must be lifted by external force, such as a crane, to allow vehicles to pass in an emergency; fixed integrated height limit frames are mainly used for portal frames at the entrances of bridges, culverts and tunnels, and are generally made of welded steel structures to protect bridges, culverts and tunnels; there are signs on them with the height limit in meters to alert vehicles.
[0003] Fixed height limit frames are low in cost, but their structure is usually difficult to adjust. When they need to be released under special circumstances, they can only be dismantled, and the dismantling work may directly cause irreversible damage to them. Even if they can be dismantled, the dismantling work is relatively cumbersome. For this reason, adjustable height limit frames were born, which are divided into manual height limit frames and electric height limit frames. Manual height limit frames can manually lift the height limit pole when needed through a manual device; electric height limit frames are divided into electric height limit frames, electric hydraulic height limit frames, pneumatic height limit frames, etc. Manually lifting height limit frames require direct manipulation of the crossbar, so their operation is not very convenient, but they will not cause damage to the height limit frame. Electric, pneumatic, and hydraulic height limit poles are expensive and costly. Since there are not many opportunities to adjust the height limit frame in actual use, this will cause unnecessary waste of resources and increase the cost of use. Therefore, in order to solve the above problems, the present application provides a municipal road height limit frame.
[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

DETAILED DESCRIPTION
[0019] The following is combined with Figure 1 - Figure 3 This application is described in further detail.
[0020] Embodiment 1:
[0021] Reference Figure 1 - Figure 3 A municipal road height limit frame includes a column 1, the top of the column 1 is rotatably connected with a cross bar 3, the free end of the cross bar 3 is welded with a C-shaped buckle 32, and a column 2 is also arranged on one side of the free end of the cross bar 3, the sliding sleeve on the column 2 is provided with a sleeve 5 which is displaced along its axial direction, the top of the sleeve 5 and the buckle 32 are detachably plugged and limited, when the sleeve 5 and the buckle 32 are separated, the cross bar 3 can rotate freely around the column 1, and the bottom end of the sleeve 5 is provided with a control mechanism for adjusting its height.
[0022] A support ring 52 and a limiting section 51 are welded to the top of the sleeve 5. The limiting section 51 is slidably inserted into the inner side of the buckle 32, and the diameter of the limiting section 51 is larger than the opening spacing of the buckle 32. The support ring 52 fits the lower edge of the buckle 32, and the diameter of the support ring 52 is larger than the inner diameter of the buckle 32. The connection between the limiting section 51 and the buckle 32 limits the position of the buckle 32, thereby ensuring the stable position of the cross piece 3. The diameter of the limiting section 51 limits the buckle 32 from escaping from the limiting section 51, thereby completing the limitation of the free end of the cross piece 3. The function of the support ring 52 is to support the bottom of the buckle 32 to ensure that the cross piece 3 is in a horizontal state.
[0023] The operating mechanism includes a prism section 53 welded at the bottom end of the sleeve 5, and a plurality of grooves 54 are provided on the prism section 53. The prism section 53 preferably adopts a hexagonal prism so that the device can be operated with a large wrench. The function of the groove 54 is to insert steel pipes and other components inside it to replace the wrench to operate the sleeve 5; an insertion section 21 is welded to the top of the column 2, and a threaded section 22 is provided at the bottom end of the insertion section 21. The height of the threaded section 22 determines the axial displacement distance of the limit section 51. The height of the threaded section 22 needs to be greater than the axial displacement of the limit section 51 to ensure that the limit section 51 can be pulled out of the buckle 32, and the cross bar 3 can move freely at this time.
[0024] A two-section sheathing tube 4 is sleeved on the outer side of the top of the column 1, and the two sections of the sheathing tube 4 are fixedly connected by bolts 7 and fixed on the outer wall of the column 1. A collar 31 is vertically welded at one end of the cross piece 3, and the collar 31 is slidably sleeved on the outer side of the sheathing tube 4. Two limiting rings 6 that cooperate with each other are arranged above the sheathing tube 4, and the two limiting rings 6 are fixedly connected by bolts 7. The two-section structure of the sheathing tube 4 allows it to be adjusted in height according to actual needs, thereby changing the height of the cross piece 3 and increasing the scope of application of the device. The collar 31 and the sheathing tube 4 are clearance-matched and slided with each other, so that the cross piece 3 can rotate around the collar 31. After rotation, the collar 31 can lose its obstruction to the road above, and the limiting section 51 limits the axial position of the collar 31 to prevent it from axial displacement.
[0025] Height limit frames are usually used for bridges and culverts, and the height of the height limit frames is usually lower than the maximum height of the bridges and culverts. Therefore, some vehicles that cannot pass through the height limit frames can pass through the buildings after reporting if the vehicle height does not exceed the actual height of the bridges and culverts, but they need to slow down and observe when passing to avoid causing irreversible damage to the bridges and culverts. Therefore, the height limit frames still need to be released when necessary.
[0026] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
