Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, the town road deceleration strip disclosed in this embodiment includes a mounting groove 1 which is opened on the ground 5 along the vertical direction, a mounting seat 2 which is fixedly arranged in the mounting groove 1, and a plurality of strip units 3 which are arranged to form a long strip deceleration strip. The mounting seat 2 is fixedly connected to the mounting groove 1 through cement pouring. The belt unit 3 includes a steel base 31 mounted above the mount 2 and a rubber layer 32 mounted on the steel base 31. The surface of the rubber layer 32 is provided with a reflective sheet (not shown in the figure), the rubber layer 32 is connected in a sliding way along the length direction of the steel base 31 and is fixed on the steel base 31 in a limiting way along the height direction, and a connecting component 4 for installing and lifting the steel base 31 is also arranged between the steel base 31 and the installation base 2. The rubber layer 32 and the steel base 31 are provided with friction lines (not shown in the figure) on the surfaces.

When replacing the rubber layer 32, the steel base 31 of the belt unit 3 is first raised in the vertical direction by the connecting assembly 4, so that the steel base 31 is raised above the upper end surface of the rubber layer 32 of the adjacent belt unit 3. Rubber layer 32 after will wearing and tearing is taken out from steel base 31 one side to change new rubber layer 32, rethread coupling assembling 4 falls steel base 31 and rubber layer 32, makes steel base 31 butt in ground 5, through can changing the easy wearing and tearing but the less rubber layer 32 of bad effect of slowing down, guarantees the speed reduction effect of deceleration strip. And the practical effect of the speed bump is improved by arranging the light reflecting sheets and the friction grains on the rubber layer 32.

Referring to fig. 1, the steel base 31 includes a bottom plate 311 and a limiting member 312 fixedly disposed at a middle position of the bottom plate 311 along a length direction of the bottom plate 311, a bottom end of the bottom plate 311 abuts against the mounting base 2 and the ground 5, and a top end of the limiting member 312 is umbrella-shaped and forms an embedding groove 313 with the bottom plate 311 for embedding and limiting the rubber layer 32. An umbrella-shaped sliding groove 321 is correspondingly formed in the lower end face of the rubber layer 32 along the vertical direction, and the limiting member 312 is embedded in and slidably connected to the sliding groove 321. The top end of the limiting member 312 and the two sides of the steel base 31 are in the same arc surface.

When the rubber layer 32 is replaced, the rubber layer 32 is pulled out from one end of the steel base 31 along the length direction thereof, a new rubber layer 32 is slid into the steel base 31 from one side, and the stopper 312 slides in the sliding groove 321, and plays a role of height limitation on the rubber layer 32 by being embedded in the sliding groove 321. After the outermost rubber layer 32 is worn, the steel base 31 is partially exposed, and the top end of the limiting piece 312 and the two sides of the steel base 31 are set to be arc surfaces of the same arc line, so that even if the rubber layer 32 on the outer surface is worn, the steel base 31 which is not easy to wear and the partial rubber layer 32 embedded in the steel base 31 can still form a complete arc, and the passing stress of a vehicle is balanced.

Referring to fig. 2, the connection assembly 4 includes a mounting bolt 41 and a rotation lever 42. The stopper 312 has a threaded hole 43 formed in the middle thereof in the height direction, and the mounting bolt 41 is screwed into the threaded hole 43. The mounting bolt 41 is hollow and has an open upper end, and the upper surface of the mounting base 2 is provided with a rotating groove 21 having an inverted T-shaped cross section along the height direction. The lower end of the mounting bolt 41 is embedded and rotatably connected in the rotating groove 21, and is fixed on the mounting seat 2 along the vertical direction in a limiting manner through the rotating groove 21. Dwang 42 inlays to establish and follows vertical direction sliding connection in the middle of construction bolt 41, and dwang 42 is equipped with stopper 421 along its radial fixation, has seted up spacing groove 411 in the construction bolt 41, and stopper 421 inlays to establish and sliding connection in spacing groove 411 to realize its circumference through spacing groove 411 and fix. An adjusting nut 422 is fixedly connected to the top end of the rotating rod 42.

When the rubber layer 32 needs to be replaced, the rotating rod 42 is pulled out from the mounting bolt 41 by one section, the rotating rod 42 is rotated by rotating the adjusting nut 422 through a tool, the rotating rod 42 is circumferentially limited between the rotating rod 42 and the mounting bolt 41, so the rotating rod 42 drives the mounting bolt 41 to synchronously rotate, and the mounting bolt 41 is limited in the height direction of the mounting seat 2, so the mounting bolt 41 rotates to enable the steel base 31 in threaded connection with the mounting bolt 41 to ascend along the vertical direction to the rubber layer 32, which is higher than the adjacent rubber layer 32 with the belt unit 3, on the upper end face of the bottom plate 311, the rubber layer 32 can be pulled out from one end of the steel base 31, and the rubber layer 32.

The implementation principle of the embodiment is as follows:

1. through the dual material setting of steel base 31 and rubber layer 32, make belt unit 3 before not wearing and tearing, through outer rubber layer 32 and vehicle contact, make the vehicle damage degree when passing through less, after belt unit 3 has used a period, outer rubber layer 32 wearing and tearing, steel base 31 in the rubber layer 32 exposes, because the construction bolt 41 that is used for connecting steel base 31 and mount pad 2 sets up in screw hole 43, can not expose in ground 5, so can not cause the influence to the vehicle.

2. After the rubber layer 32 is worn, when the rubber layer 32 needs to be replaced, the rotating rod 42 is pulled out from the mounting bolt 41 by one section, the rotating rod 42 is rotated by rotating the adjusting nut 422 through a tool, because the circumferential direction between the rotating rod 42 and the mounting bolt 41 is limited, the rotating rod 42 drives the mounting bolt 41 to rotate synchronously, because the height direction of the mounting bolt 41 is limited on the mounting seat 2, the mounting bolt 41 rotates to enable the steel base 31 which is in threaded connection with the mounting bolt 41 to ascend along the vertical direction to the rubber layer 32, the upper end face of the bottom plate 311 is higher than the adjacent rubber layer 32 with the unit 3, the rubber layer 32 can be pulled out from one end of the steel base 31, and the rubber layer 32 is convenient to.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
