The bridge support device with a roof reduction structure: by providing a control component, the output shaft of the motor drives the threaded rod to move, the movable plate on the threaded rod moves, the support rod fixed on the surface of the movable plate moves toward the outside of the fixed column, and the ladder fixed on the surface of the support rod moves synchronously toward the outside of the fixed column, thereby achieving the purpose of adjusting the height of the ladder, thereby enhancing the practicality of the device.

[0004] Referring to the shock absorption problem in the comparative documents, shock absorbing parts are used between the bearings and the piers for shock absorption. Since the shock absorption effect is only achieved through four groups of shock absorbing parts, the four groups of shock absorbing parts are concentrated at the bottom of the bearings, resulting in uneven vibration pressure transmitted from the bridge deck, thus affecting the shock absorption effect.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The following is combined with Figure 1-4 The utility model is described in further detail.

[0029] The utility model discloses a road bridge shock absorbing device, comprising a damper 3, a transition plate 15 is arranged at the bottom of the damper 3, a bridge pier 1 is arranged below the transition plate 15, steel plate frames 5 are inserted and installed at positions near the tops on both sides of the pier 1, wherein a boss is arranged on one side of the steel plate frame 5 close to the pier 1, and sliding holes that slide with the boss are opened on both sides of the pier 1. The outside of the pier 1 is sleeved with a sleeve plate 2 11, and the outside of the pier 1 is sleeved with a sleeve plate 10 below the sleeve plate 2 11. The vertical opening between the sleeve plates 10 and 11 is larger than the cross-sectional width of the pier 1. Vertical rods 2 17 are passed through the top of the steel plate frame 5 near the edges on both sides. A vertical rod 13 is vertically passed through the steel plate frame 5 on one side of the vertical rod 2 17. The tops of the vertical rods 2 17 and 13 are fixedly connected with a connecting piece 14 between the support 16. Shock-absorbing springs 1 6 and 2 12 are fixed at the bottom of the connecting piece 14 outside the vertical rods 2 17 and 13 respectively. A fixing piece 7 is fixed above the steel plate frame 5 and outside the vertical rods 13 and 17, and the upper surface of the fixing piece 7 is fixedly connected to the shock-absorbing spring 1 6 or the upper surface of the fixing piece 7 is fixedly connected to the shock-absorbing spring 2 12. The vibration-reducing spring 12 and the vertical rod 13 cooperate to achieve a shock-reducing effect, and the vertical rod 13 is compressed; the vibration-reducing spring 16 and the vertical rod 17 cooperate to further achieve a shock-reducing effect, and at the same time, the vertical rod 17 and the vertical rod 13 increase the bearing point of the support 16.

[0030] A support 16 is provided at the top of the damper 1 3, and a shock absorbing member 2 is provided between the bottom of the support 16 and the transition plate 15. A support 16 is provided above the transition plate 15, and dampers 2 4 are installed at the bottom corner of the transition plate 15 and at the top of the pier 1. The initial shock absorption of the support 16 is achieved through the shock absorbing member 2, and the initial shock absorption effect of the support 16 is further achieved through the damper 2 4.

[0031] The top of the second sleeve plate 11 and the first sleeve plate 10 are provided with a slide groove 8, and the bottom of the second vertical rod 17 and the first vertical rod 13 are fixed with a slider 9, and the slider 9 is located in the slide groove 8. The slider 9 and the slide groove 8 are both T-shaped, and the slider 9 and the second sleeve plate 11 or the slider 9 and the first sleeve plate 10 form a sliding structure through the slide groove 8. When the support 16 expands and contracts due to heat, the second vertical rod 17 and the first vertical rod 13 will be driven to move together. At this time, the slider 9 slides and translates along the slide groove 8 on the sleeve plate 10 and the second sleeve plate 11, thereby ensuring the verticality of the second vertical rod 17 and the first vertical rod 13 and avoiding bending.

[0032] The implementation principle of a road bridge shock absorbing device of the utility model is:

[0033] First, when vibration occurs, the shock absorbing member 2, damper 1 3 and damper 2 4 are used to achieve the initial shock absorbing effect, and then the shock absorbing spring 2 12 and vertical rod 1 13 cooperate to achieve the shock absorbing effect again, and the vertical rod 1 13 is compressed at this time; similarly, the shock absorbing spring 1 6 and vertical rod 2 17 cooperate to further achieve the shock absorbing effect, and the shock absorbing spring 1 6 is compressed, which can increase the shock absorbing points supporting the bridge pier 1. Secondly, when the support 16 expands and contracts due to heat, the vertical rod 1 13 and the vertical rod 2 17 will both move, and at the same time drive the steel plate frame 5 to move. The cooperation of the slide groove 8 and the slider 9 will not cause the steel plate frame 5 and the bridge pier 1 to separate, thus ensuring that the vertical rod 1 13 and the vertical rod 2 17 will not be deformed when the support 16 is subjected to thermal expansion and contraction, thereby extending the service life.
