[0001] The utility model relates to the technical field of bridge pile foundations, in particular to a bridge pile foundation protection device. Background Art

[0002] Bridge pile foundation is an important part of the bridge construction process. The pile foundation is connected to the pier through the base to support the bridge. Among them, the common pile-type pier requires the pile foundation to extend out of the soil layer, and a part of it is used as the pier. It has the characteristics of saving materials, simple construction and simple appearance, but its collision resistance is poor. Therefore, protective devices are needed to support and protect the bridge pile foundation extending out of the soil to enhance its structural stability.

[0003] At present, common pile foundation protection devices usually directly put a protective cover on the outside of the pile foundation for protection. However, since the diameter of the pile foundation will change accordingly with the different bridge loads it carries, the use of a simple protective cover structure cannot be effectively applied to a variety of pile foundations. The protective cover and the pile foundation are not tightly fitted, resulting in poor protection effect. Therefore, a bridge pile foundation protection device is urgently needed to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] 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 of 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.

[0025] like Figure 1-Figure 5As shown, a bridge pile foundation protection device includes a base 1, a pile foundation 4 is fixedly arranged inside the base 1, and a cap 10 is fixedly connected to the upper end of the pile foundation 4. The pile foundation 4 is responsible for bearing the gravity of the cap 10, receiving and transmitting the vibration transmitted from the top of the cap 10. The device also includes a first ring mechanism 2, a movable mechanism 8 and an adjusting bolt 5. The first ring mechanism 2 includes an inner ring plate 201, which is fixedly connected to the top of the base 1, and the inner ring plate 201 is coaxially arranged around the outside of the pile foundation 4. A plurality of groups of movable cavities 202 are equidistantly arranged on the inner wall of the inner ring plate 201 near the top; the movable mechanism 8 is provided with a plurality of groups, each group of movable mechanisms 8 is arranged inside a corresponding movable cavity 202, and each group of movable mechanisms 8 includes a slider 801, each group of sliders 801 is slidably connected to the inside of the corresponding movable cavity 202, and the slider 801 can slide along the movable cavity 202, and the slider 801 is close to the corresponding movable cavity. One side of the cavity 202 is provided with an inclined surface 802, and each group of inclined surfaces 802 is inclined downward in a direction away from the pile foundation 4; the adjusting bolts 5 are provided in multiple groups and are equidistantly distributed around the top of the inner ring plate 201, and the bottom of each group of adjusting bolts 5 is threadedly connected in the corresponding movable cavity 202 and cooperates with the corresponding inclined surface 802. The inclined surface 802 on one side of the slider 801 is squeezed by the adjusting bolts 5, so that the slider 801 is subjected to the lateral component force, thereby driving multiple sliders 801 to slide laterally toward the middle and surround and squeeze the side of the pile foundation 4; after the device is installed on the side of the pile foundation 4, the adjusting bolts 5 can be rotated to squeeze the inclined surface 802, thereby pushing the slider 801 to squeeze the side wall of the pile foundation 4, completing the surrounding, fixing and clamping operation of the multiple sliders 801 on the pile foundation 4, and by adjusting the sliding distance of the multiple groups of sliders 801, the effect of being adaptable to pile foundations 4 of different diameters can be achieved.

[0026] In some specific implementation schemes, in order to ensure the stability of the slider 801 during the sliding process, side plates 806 are fixedly connected on both sides of the slider 801, and a slide bar 805 is fixedly connected to the top of each group of side plates 806. A guide groove 203 matching the slide bar 805 is opened at the top of the movable cavity 202, and the guide groove 203 extends to the inner side of the inner ring plate 201. The width of the slide bar 805 is the same as the width of the guide groove 203, and they are interlocked with each other; when the slider 801 is displaced under the extrusion of the adjusting bolt 5, it will drive the slide bar 805 to displace along the guide groove 203, thereby ensuring that the slider 801 will move stably in a straight line along the direction close to the pile foundation 4.

[0027] In some specific implementation schemes, in order to ensure that the slider 801 does not slide out of the active cavity 202, a limiting body 204 is fixedly connected to the opening of each group of active cavities 202, and a limiting block 804 cooperating with the limiting body 204 is fixedly connected to the side of the side plate 806 away from the slider 801, and the limiting body 204 is located on the moving path of the limiting block 804, and the limiting block 804 is slidingly connected to the wall of the active cavity 202; in the process of the slider 801 moving toward the center of the inner ring plate 201 along the active cavity 202, the limiting block 804 will be slidingly connected to the wall of the active cavity 202 until the limiting block 804 contacts the limiting body 204, at which time the limiting body 204 will block one side of the limiting block 804, thereby preventing the limiting block 804 and the slider 801 from sliding out of the active cavity 202.

[0028] In some specific implementation schemes, in order to ensure the clamping effect, each set of sliders 801 is provided with an arc-shaped groove body that matches the pile foundation 4 on the side close to the pile foundation 4; the arc-shaped groove body will increase the contact area with the pile foundation 4, and at the same time increase the friction between the pile foundation 4 and the slider 801, thereby improving the clamping effect.

[0029] In some specific implementation schemes, in order to maintain the relative position between the adjusting bolts 5 and the inner ring plate 201, each group of adjusting bolts 5 is threadedly sleeved with a locking nut 9; after the adjusting bolts 5 are rotated to drive the slider 801 to squeeze the pile foundation 4, in order to maintain the relative state of the adjusting bolts 5 and the inner ring plate 201 and avoid vibration or other reasons that cause the pile foundation 4 to become loose, the locking nut 9 on the side of the adjusting bolt 5 can be rotated so that the locking nut 9 squeezes the top of the inner ring plate 201, thereby increasing the pressure between the adjusting bolts 5 and the inner ring plate 201, and then increasing the friction between the two, thereby ensuring the stability of the relative position of the adjusting bolts 5 and the inner ring plate 201.

[0030] In some specific implementation schemes, in order to enhance the protective effect of the protective device, a second ring 3 is coaxially fixedly sleeved on the outer side of the inner ring plate 201, and the second ring 3 is a hollow truncated cone structure; the inner ring plate 201 and the second ring 3 cooperate to form a truncated cone-shaped protective structure, and the inclined setting of the outer side of the second ring 3 is utilized to resist external forces acting on the second ring 3 from the horizontal direction.

[0031] In some specific implementation schemes, in order to reduce the impact of the slider 801 on the pile foundation 4 during implementation, each group of sliders 801 is fixedly connected to a rubber pad 803 that matches the pile foundation 4 on the side close to the pile foundation 4. The rubber pad 803 is soft in texture and is arranged in an arc shape on the side away from the slider 801. When the slider 801 approaches the pile foundation 4, the rubber pad 803 will first contact the side of the pile foundation 4. While playing a buffering role, it can also prevent the side of the pile foundation 4 from being damaged by the slider 801, and can also serve as a vibration buffer pad between the pile foundation 4 and the slider 801 to alleviate the vibration transmitted from the top of the base 10.

[0032] In some specific implementation schemes, in order to ensure the stability of the device after installation, a plurality of groups of through holes 6 are equidistantly arranged on the second ring 3, and a corresponding fixing bolt 7 is fixedly sleeved inside each group of through holes 6, and the bottom of the fixing bolt 7 is inserted into the ground or other devices that are convenient for fixing; the bottom end of the fixing bolt 7 inserted into the second ring 3 is arranged on the outside of the base 1, which can further enhance the connection stability between the protective device and the pile foundation 4 and ensure the protective effect.

[0033] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0034] After the device is installed on the side of the pile foundation 4, the adjusting bolt 5 can be rotated to squeeze the inclined surface 802, thereby pushing the slider 801 to squeeze the side wall of the pile foundation 4, completing the surrounding fixed clamping operation of multiple sliders 801 on the pile foundation 4. By adjusting the sliding distance of multiple groups of sliders 801, the effect of adapting to pile foundations 4 of different diameters can be achieved. When the slider 801 is displaced under the squeezing action of the adjusting bolt 5, it will drive the slide bar 805 to displace along the guide groove 203, thereby ensuring that the slider 801 will move stably in a straight line along the direction close to the pile foundation 4. In the process of the slider 801 displacing along the active cavity 202 toward the center of the inner ring plate 201, the limit block 804 will be slidably connected with the cavity wall of the active cavity 202 until the limit block 804 contacts the limit body 204. At this time, the limit body 204 will block one side of the limit block 804, thereby preventing the limit block 804 and the slider 801 from sliding out of the active cavity 202;

[0035] When the slider 801 approaches the pile foundation 4, the rubber pad 803 will first contact the side of the pile foundation 4. While playing a buffering role, it can also prevent the side of the pile foundation 4 from being damaged by the slider 801, while increasing the friction between the pile foundation 4 and the clamping surface. It can also serve as a vibration buffer between the pile foundation 4 and the slider 801 to alleviate the vibration transmitted from the top of the cap 10. After the adjusting bolt 5 is rotated to drive the slider 801 to squeeze the pile foundation 4, in order to maintain the relative state of the adjusting bolt 5 and the inner ring plate 201 and prevent the pile foundation 4 from being loosened due to vibration or other reasons, the locking nut 9 on the side of the adjusting bolt 5 can be rotated so that the locking nut 9 squeezes the top of the inner ring plate 201, thereby increasing the pressure between the adjusting bolt 5 and the inner ring plate 201, and then increasing the friction between the two, ensuring the stability of the relative position of the adjusting bolt 5 and the inner ring plate 201;

[0036] The fixing bolt 7 passing through the second ring 3 has its bottom end arranged outside the base 1, which can further enhance the connection stability between the protective device and the pile foundation 4 and improve the protective effect.

[0037] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
