Description

Technical Field

[0001] This utility model relates to the field of highway technology, specifically a device for suppressing the floating of steel cages in highway bridge pile foundations. Background Technology

[0002] Highways, or expressways for short, are roads specifically designed for high-speed automobile travel.

[0003] When the reinforcing cage is relatively light, the buoyancy of the concrete may be greater than the sum of the weight of the reinforcing cage and the friction between it and the borehole wall, causing it to float. In addition, problems such as bending of the main reinforcement bars and overall twisting of the cage may also increase the risk of floating, making it difficult to suppress the floating of the reinforcing cage. To address these issues, we provide a device for suppressing the floating of reinforcing cages in highway bridge pile foundations. Utility Model Content

[0004] The purpose of this invention is to provide a device for suppressing the floating of steel cages in highway bridge pile foundations, in order to solve the problems raised in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for suppressing the floating of a steel cage in a highway bridge pile foundation, comprising a steel cage body and a control and protection shell. A linkage force-applying disc is rotatably connected to the inner wall of the control and protection shell. A linkage force-bearing column is slidably connected within a control groove on the linkage force-applying disc. A control linkage slider is fixedly connected to one end of the linkage force-bearing column. A pressure-applying plate is fixedly connected to the top of the control linkage slider. The pressure-applying plate contacts the steel cage body. The tight fit between the components effectively suppresses the floating of the steel cage body by adding this device to the outside of the steel cage body.

[0006] Preferably, the steel cage body includes main reinforcing bars, which are fixedly connected to stirrups. Both the main reinforcing bars and the stirrups are main components of the steel cage body.

[0007] Preferably, the position control linkage slider is slidably connected within a guide groove in the position control protective shell, and the guide groove determines the movement direction of the position control linkage slider.

[0008] Preferably, a transition linkage ring is fixedly connected to the bottom of the linkage force application plate. The transition linkage ring is fixedly connected to the top of the planar worm gear ring. The planar worm gear ring can effectively drive the transition linkage ring to rotate.

[0009] Preferably, the teeth on the outer circumferential surface of the planar worm gear ring mesh with the threads on the outer circumferential surface of the one-way worm. The one-way worm can effectively drive the planar worm gear ring to rotate.

[0010] Preferably, the outer circumferential surface of the unidirectional worm gear is rotatably connected to the inner wall of the control and protection housing. The control and protection housing provides a control effect on multiple different components.

[0011] Preferably, one end of the unidirectional worm gear is fixedly connected to an external turntable, and the outer circumferential surface of the external turntable is provided with anti-slip texture, which facilitates the rotation of the external turntable.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 and Figure 3 As shown, this utility model provides a technical solution for a device to suppress the floating of a steel cage in a highway bridge pile foundation. The device includes a steel cage body 1 and a control and protection shell 2. The control and protection shell 2 can effectively protect its internal components, preventing them from being disturbed by external factors and allowing them to move more stably. A linkage force-applying plate 3 is rotatably connected to the inner wall of the control and protection shell 2. The control and protection shell 2 can effectively support the linkage force-applying plate 3 and apply a control effect, ensuring that the linkage force-applying plate 3 can rotate in place.

[0025] like Figure 3 and Figure 5 As shown, a transition linkage ring 9 is fixedly connected to the bottom of the linkage force application plate 3. The transition linkage ring 9 is fixedly connected to the top of the planar worm gear ring 10. The purpose of setting the transition linkage ring 9 is to enable the linkage force application plate 3 and the planar worm gear ring 10 to maintain the linkage effect.

[0026] like Figure 6 As shown, the teeth on the outer circumferential surface of the planar worm gear ring 10 mesh with the threads on the outer circumferential surface of the one-way worm 11. The tight fit between the planar worm gear ring 10 and the one-way worm 11 can effectively achieve the force transmission effect. When the one-way worm 11 rotates, it can effectively drive the planar worm gear ring 10 to move. At the same time, it has a self-locking effect, avoiding the problem of rebound after the movement of subsequent components.

[0027] like Figure 6 As shown, one end of the one-way worm gear 11 is fixedly connected to an external turntable 12. The one-way worm gear 11 and the external turntable 12 maintain a linkage effect. The outer circumferential surface of the external turntable 12 is provided with anti-slip texture. The setting of the external turntable 12 makes it easy for the operator to drive the one-way worm gear 11 to rotate, and it is not easy for slippage to occur during the rotation process.

[0028] like Figure 3 , Figure 5 and Figure 6 As shown, the outer circumferential surface of the one-way worm gear 11 is rotatably connected to the inner wall of the control and protective housing 2. The control and protective housing 2 can also support the one-way worm gear 11 and apply a control effect, thereby ensuring that the one-way worm gear 11 can rotate in place. The control groove 4 of the linkage force plate 3 is slidably connected to the linkage force column 5. The setting of the control groove 4 can effectively determine the maximum distance that the linkage force column 5 can move, while ensuring that the linkage force plate 3 can apply force to the linkage force column 5.

[0029] like Figure 2 and Figure 3 As shown, a control linkage slider 6 is fixedly connected to one end of the linkage force-bearing column 5. The linkage force-bearing column 5 and the control linkage slider 6 maintain a linkage effect. The control linkage slider 6 is slidably connected in the guide groove 8 opened in the control protective shell 2. The control linkage slider 6 and the guide groove 8 match, so that the control protective shell 2 applies a control effect to the control linkage slider 6, ensuring that the movable position of the control linkage slider 6 will not be deviated, and keeping the linkage force-bearing column 5 stable.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a pressure plate 7 is fixedly connected to the top of the control linkage slider 6. The control linkage slider 6 and the pressure plate 7 maintain a linkage effect. The pressure plate 7 contacts the steel cage body 1. The setting of the pressure plate 7 can effectively apply pressure to the steel cage body 1, so that the floating suppression device can be stably installed at the designated position of the steel cage body 1.

[0031] like Figure 1 and Figure 7 As shown, the main reinforcement cage 1 includes a main reinforcing bar 101, which is fixedly connected to a stirrup 102. The tight fit between the main reinforcing bar 101 and the stirrup 102 forms the main reinforcement cage 1, which mainly plays a tensile role. Concrete has high compressive strength but very low tensile strength, which restrains the concrete of the pile body, enabling it to withstand a certain axial tensile force. During the construction of highway bridge pile foundations, pile driving may be required according to the requirements. The method is to use machine punching and water grinding to drill holes, and the hole depth reaches the design requirements. Then, the reinforcement cage is lowered into the pile hole, and then the guide pipe is inserted for concrete pouring. The pressure plate 7 is used to press down the stirrup 102, and the main reinforcing bar 101 passes through the central groove of the floating suppression device.

[0032] Working Principle: During use, the steel cage body 1 needs to be passed through the groove in the middle of the control and protection shell 2 according to the specific situation. Then, by manually rotating the outer turntable 12, the outer turntable 12 will drive the one-way worm gear 11 to rotate in place within the control and protection shell 2. At this time, because the transition linkage ring 9, which is connected to the planar worm wheel ring 10, is also controlled by the control and protection shell 2 through the linkage force application plate 3, the one-way worm gear 11 will drive the planar worm wheel ring 10, together with the transition linkage ring 9, to rotate in place within the control and protection shell 2. During this process, there will be no jamming. The transition linkage ring 9 will drive the linkage force application plate 3 to move synchronously within the control and protection shell 2. At this time, because the control linkage slider 6, which is connected to the linkage force-bearing column 5, is also controlled by the control and protection shell 2... The guide groove 8 restricts the movement of the linkage force-applying plate 3, which drives the linkage force-bearing column 5 to slide the control linkage slider 6 within the guide groove 8. This causes the pressure plate 7 to move, making it contact the force-bearing stirrup 102 and apply pressure to it. This achieves the purpose of stably installing the buoyancy suppression device outside the steel cage body 1. Then, the steel cage body 1, together with the buoyancy suppression device, is placed into the pile hole. During concrete pouring, the buoyancy suppression device increases the contact area between the steel cage body 1 and the concrete, thus increasing the force required for the steel cage body 1 to float. This effectively suppresses the floating steel cage body 1 and ensures its stability.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
