Abstract
Description
Technical Field
[0001] This invention relates to the field of rebar cage positioning technology, and in particular to a rebar cage positioning device for cement pile foundation construction. Background Technology
[0002] In cement pile foundation construction, it is necessary to install a reinforcing cage in the grouting hole before subsequent pouring. The positioning of the reinforcing cage directly affects the quality of its subsequent formation. It is necessary to keep the reinforcing cage and the grouting hole concentric and vertical. Current reinforcing cage positioning devices mainly use ring clamps to hold the reinforcing bars for positioning. This is not convenient for automatic control to prevent the reinforcing cage from floating. The traditional method of counterweight pulling makes it difficult to control and stop pouring in time, resulting in a large continuous upward force on the reinforcing cage, affecting its stability and vertical accuracy. It is also not convenient to automatically detect the rolling jamming of the reinforcing cage pads and the deformation of the reinforcing cage during hoisting. This can easily cause significant wear on the grouting hole wall and even hole collapse. At the same time, it is necessary to prevent the stirrups from being stressed when clamping and positioning the reinforcing cage, especially for long reinforcing cages, which can easily cause the stirrups to detach.

The prompt is simple and intuitive, which can facilitate the staff or supervisors to know in a timely manner.
[0038] In Embodiment 2, based on Embodiment 1, the positioning sliding component 5 includes: a lifting slider 501, a pressing spring 502, and a pressing switch 503. The lifting slider 501 is slidably mounted inside the positioning mounting ring 101; the pressing spring 502 is fixedly mounted at the bottom of the lifting slider 501, and the bottom of the pressing spring 502 is fixedly mounted inside the positioning mounting ring 101; the pressing switch 503 is fixedly mounted at the top of the lifting slider 501, and the top of the pressing switch 503 is pressed against the inner side of the positioning mounting ring 101; the positioning sliding component 5 also includes: a telescopic block 504 and a telescopic spring 5041, the telescopic block 504... 4. A sliding connector is inserted into the side of the lifting slider 501; a telescopic spring 5041 is fixedly installed at the tail of the telescopic block 504, and the telescopic spring 5041 is located inside the lifting slider 501; the end of the telescopic spring 5041 is fixedly connected to the inside of the lifting slider 501; the pressure switch 503 is electrically connected to the accuracy indicator light 103; the resistance detection component 6 includes: an arc plate 601 and a rubber pad 602, the arc plate 601 is fixedly installed on the telescopic block 504; the rubber pad 602 is fixedly installed on the arc plate 601, and the inner side of the top of the rubber pad 602 is a sloping structure, and a rotatable concrete is usually installed on the outside of the reinforcing cage. Soil pads facilitate rolling and conforming to the grouting hole wall while supporting the reinforcing cage, ensuring the thickness of the outer retaining wall. The inner diameter of a ring of rubber pads 602 is smaller than the diameter formed by a ring of concrete pads on the outside of the reinforcing cage. A resistance detection element 6, in conjunction with a positioning sliding element 5, tests the straightness of the reinforcing cage during lowering, preventing serious deviations in straightness and providing direct alerts. Simultaneously, during lowering, the system automatically detects whether the pads on the outside of the reinforcing cage are rolling normally, preventing excessive friction caused by broken pads or external stones jamming the pads as they move down the grouting hole wall, potentially leading to... If the reinforcing cage bends due to factors such as hoisting, it will no longer be coaxial. When it passes through a rubber pad 602, the bent and protruding part of the reinforcing cage will squeeze the rubber pad 602, pushing the telescopic block 504 to retract and compressing the telescopic spring 5041. As the reinforcing cage is lowered, the friction is greater, which will cause the rubber pad 602 to rub against it, driving the lifting slider 501 to move down and compressing the pressing spring 502. At this time, the pressing switch 503 is also driven down, no longer squeezing and fitting the inner side of the positioning and mounting ring 101. The accuracy indicator light 103 can then be controlled to light up, and manual inspection can be performed in time.
[0039] The working principle of this embodiment is as follows: First, the positioning installation ring 101 is firmly anchored to the ground by a ring of anchor rods. Before lowering the reinforcing cage into the grouting hole, the clamping plates 302 on each rotating adjustment ring 301 are manually rotated to open, so as to prevent the clamping plates 302 from obstructing the reinforcing cage during subsequent lowering. Then, the reinforcing cage is hoisted above the positioning installation ring 101 by a crane, and then lowered into the grouting hole. When the reinforcing cage needs to be positioned, the two clamping plates 302 on the same side are rotated respectively to clamp the vertical bars of the reinforcing cage by clamping bolts 303. The auxiliary bolts 304 can be tightened to press and fit the vertical bars for positioning. When the two clamping plates 302 clamp the vertical bars of the reinforcing cage for positioning and grouting or connecting extended reinforcing cages, if the distance between the two clamping plates 302 and the upper stirrups is too close, or if the clamping plates 302 slip, the reinforcing cage may fall. When the rebar cage stirrups press down on the stirrup lower bar 403, the lower bar block 401 presses down on the stirrup switch 402, and the control connection prompt buzzer 104 directly sounds a prompt. At the same time, when it is necessary to assemble the rebar cage, the lower rebar cage can be positioned by the vertical bar clamp 3 and then connected by the threaded cylinder connector. When the rebar cage needs to be fine-tuned after positioning to ensure its vertical accuracy, the corresponding fine-tuning threaded rod 102 can be rotated to drive the adjustment sliding column 201 to rise and fall. In the subsequent grouting process, the concrete is discharged into the grouting hole through the pipeline by the external grouting pump. If the rebar cage floats up during the process, the rebar cage can drive the clamping plate 302 to move up, which will drive the material pump safety switch 3011 to squeeze the upper baffle 2011. At this time, the material pump safety switch 3011 can control the grouting pump power switch to stop the grouting and avoid continuous grouting.
[0040] During the lowering of the reinforcing cage, the disc-shaped structure of the reinforcing cage pads will not cause jamming. When the reinforcing cage is lowered, in its normal vertical state, there is a gap between the outer side and the rubber pads 602. Once the reinforcing cage bends due to factors such as hoisting, it will no longer be coaxial. When passing through the rubber pads 602, the bent and protruding part of the reinforcing cage will squeeze the rubber pads 602, pushing the telescopic block 504 back and compressing the telescopic spring 5041. At this time, as the reinforcing cage is lowered, the friction is relatively large, causing friction against the rubber pads 602. 2. The lifting slider 501 moves down, compressing the pressure spring 502. At this time, the pressure switch 503 is also moved down, no longer pressing against the inner side of the positioning mounting ring 101. Similarly, when the pad of the steel cage passes normally over the rubber pad 602, the pad can rotate to reduce resistance and will not cause the lifting slider 501 to move down excessively due to friction. Conversely, if the pad gets stuck and cannot rotate, the pad will also rub against the rubber pad 602, causing the lifting slider 501 to move down excessively. The pressure switch 503 will no longer be pressed, and the control accuracy indicator light 103 will light up to indicate this.
