Description

Technical Field

[0001] The invention relates to the technical field of bridge pile foundation construction, in particular to a concrete cast-in-place pile reinforcement cage anti-deviating device. Background Art

[0002] As an important structure for transferring bridge loads to deep soil (rock), the bridge pile foundation is formed by pouring a steel cage and concrete as a whole. The accurate positioning of the steel cage directly affects the performance of the pile foundation. Before the underwater concrete construction of the concrete cast-in-place pile, the steel cage is lowered into the pile hole. The traditional plane positioning of the steel cage is carried out by welding ear bars or concrete pads. However, in actual construction, welding ear bars or concrete pads are prone to deformation and damage on site. In addition, the disturbance phenomenon during concrete pouring will cause the steel cage to deviate to a certain extent, so that the axis of the end of the steel cage does not coincide with the axis of the pile hole, which leads to uneven thickness of the steel cage protective layer. It is difficult to meet the design requirements on site.

[0003] In order to overcome the above-mentioned shortcomings, anti-deviation devices are currently used on construction sites to limit the position of the concrete pile steel cage to prevent it from deviating. The current anti-deviation device uses multiple longitudinally distributed and identical circular rings to wrap the steel cage, and then during construction, the multiple circular rings are connected up and down and hung on the steel cage. Although this method can effectively limit the position of the steel cage, it cannot completely ensure that the axis of the end of the steel cage coincides with the axis of the pile hole. For steel cages of different diameters, it is necessary to replace multiple circular rings of different sizes and re-make the anti-deviation device. Obviously, this is not easy to operate during construction. Summary of the invention

[0030] like Figure 1-4As shown, a concrete cast-in-place pile reinforcement cage anti-deviation device provided by the present invention comprises a support seat 4 arranged around the bottom of a reinforcement cage 9, a support rod 1 is arranged on the support seat 4, a propeller 3 is arranged on the side of the support rod 1 facing the reinforcement cage 9, the propeller 3 is slidably connected to the surface of the support rod 1 through a first driver, a limiting rod 7 is connected to the propulsion end of the propeller 3, the limiting rod 7 is connected to a variable circular ring 6 with a variable radius on the side facing the reinforcement cage 9, and the variable circular ring 6 is in close contact with the reinforcement cage 9 by changing its own radius;

[0031] A support plate 10 is provided on the top of the support rod 1, and the support plate 10 is located above the steel cage 9. A laser emitter 11 is provided at the center of one side of the support plate 10 facing the steel cage 9. A plurality of rangefinders 12 are also provided on one side of the support plate 10 facing the steel cage 9, and the rangefinders 12 are distributed around the laser emitter 11.

[0032] The anti-deviation device also includes a processor and a power supply. The first driver, the thruster 3, the rangefinder 12 and the variable ring 6 are respectively connected to the processor signal. The laser emitter 11, the processor, the first driver, the thruster 3, the rangefinder 12 and the variable ring 6 are respectively electrically connected to the power supply.

[0033] When using the anti-deviation device of the present invention, the anti-deviation device is prevented from being erected around the steel cage 9 so that the support plate 10 is located directly above the steel cage 9. The position of the anti-deviation device is adjusted so that the laser emitted by the laser transmitter 11 hits the axis of the steel cage 9. The laser is located on the axis of the steel cage 9. At this time, it is considered that the anti-deviation device has completed the position adjustment.

[0034] After adjusting the position of the anti-deviation device, the data detected by the rangefinder 12 acquisition device of the anti-deviation device, the distance detected by the rangefinder 12 located above the steel cage 9 will be significantly smaller than the rangefinder 12 at other positions. Therefore, the processor determines the diameter of the steel cage 9 according to the position of the rangefinder 12 with a smaller distance, thereby adjusting the diameter of the variable ring 6 according to the diameter of the steel cage 9, and at the same time, the propeller 3 is pushed forward, and finally the variable ring 6 contacts the outer side of the steel cage 9 to fix the position of the steel cage 9. At the same time, during the construction process, the position of the variable ring 6 will be moved upward in sequence. At this time, it is necessary to use the first driver to make the propeller 3 move in the up and down directions of the support rod 1.

[0035] In the present invention, for ease of understanding, the steel cage 9 is used Figure 1 The dotted line in .

[0036] The present invention locates the axis of the steel cage 9 through the laser transmitter 11, and determines the diameter of the steel cage 9 through the rangefinder 12, so that the variable ring 6 fixes the position of the steel cage 9. At the same time, based on the support of the anti-deviation device by the support mechanism around the steel cage 6 such as the support rod 1 and the support seat 4, the stability of the anti-deviation device is determined, so that the position of the variable ring 6 will not be offset, thereby effectively limiting the position and preventing the steel cage 9 from deviating. At the same time, in the present invention, through the roller at the bottom of the support seat, combined with the positioning laser emitted by the laser generator, the position of the anti-deviation device can be easily adjusted according to the axis of the steel cage, so that the anti-deviation device is aligned with the axis of the steel cage as soon as possible.

[0037] The present invention further optimizes the above anti-deviation device, wherein a plurality of rangefinder rings 13 are sequentially arranged from the inside to the outside on one side of the support plate 10 where the laser emitter 11 is arranged, and the plurality of rangefinder rings 13 are distributed in concentric circles, and at least one rangefinder 12 is arranged on each rangefinder ring 13. Among them, a plurality of rangefinders 12 are evenly arranged on each rangefinder ring 13.

[0038] There are multiple distance measuring rings 13 in the present invention, which is equivalent to being able to detect steel cages 9 of multiple diameters. Since the steel cage 9 is also cylindrical, there is at least one distance meter 12 on the distance measuring ring 13, and the distance meter 12 on each distance measuring ring 13 respectively represents the size of a steel cage 9. Therefore, at least one distance meter 12 is provided on each distance measuring ring 13. Figure 2 The dotted line in the figure represents the distance measuring ring 13. Of course, the best way is to evenly arrange a plurality of the distance measuring instruments 12 on each distance measuring ring 13 in order to eliminate erroneous data. In this way, only the data of the plurality of distance measuring instruments 12 on one distance measuring ring 13 is needed. If the plurality of distance measuring instruments 12 detect the steel cage 9, even if one or two are not detected, it will not cause the size change problem of the variable ring 6.

[0039] In the present invention, the diameter of the steel cage 9 can also be adjusted according to the artificial setting, and the authority of the artificial setting size is higher than other values. That is, even if the diameter of the steel cage 9 detected by the rangefinder 12 is 1 meter, but the size of the steel cage 9 is artificially set to 80 centimeters, the diameter adjustment of the variable ring 6 is also adjusted according to the artificial setting of 80 centimeters.

[0040] In the present invention, in order to more stably support the steel cage 9 in a limited position, there are multiple variable rings 6, and the multiple variable rings 6 are distributed longitudinally in sequence, and each of the variable rings 6 is connected to the limiting rod 7 respectively.

[0041] In the present invention, the structure of the variable ring 6 is further limited. The variable ring 6 is composed of a plurality of connecting rods 6-1 and a plurality of hinges 6-2 with adjustable hinge angles. The number of the connecting rods 6-1 is equal to the number of the hinges 6-2.

[0042] The connecting rod 6-1 and the hinge 6-2 are sequentially connected to form a ring, and two adjacent connecting rods 6-1 are hinged through one hinge 6-2;

[0043] The hinge 6 - 2 is connected to the processor signal, and the hinge 6 - 2 is electrically connected to the power supply.

[0044] In the present invention, the variable ring 6 controls each articulator 6-2 according to the required diameter size and the preset rules, so that it is transformed to a suitable angle, and finally a ring is obtained, for example Figure 3 and Figure 4 , Figure 3 It is the variable ring 6 with a larger diameter. Figure 4 It is the variable ring 6 with a smaller diameter.

[0045] For the connection between the variable ring 6 and the limiting rod 7, in order to ensure the stability of the connection and also to ensure the high consistency of each position of the variable ring 6 during operation, the limiting rod 7 is connected to any connecting rod 6-1 in the variable ring 6. One variable ring 6 is connected to at least two limiting rods 7, and at this time, the positions of the two limiting rods 7 are opposite.

[0046] The present invention provides a concrete cast-in-place pile reinforcement cage anti-deviation device, wherein the variable ring 6 changes the diameter of the ring according to the change of the hinge angle of each hinge 6-2, so that the anti-deviation device of the present invention can be applied to reinforcement cages 9 of various sizes.

[0047] In the present invention, in order to facilitate the position adjustment of the anti-deviation device and make the laser in the anti-deviation device coincide with the axis position in the steel cage 9 as soon as possible, a plurality of rollers 5 are arranged at the bottom of the support seat 4, and the rollers 5 are driven by a second driver; the second driver is connected to the processor signal, and the second driver is electrically connected to the power supply.

[0048] The construction workers communicate with the processor, which can be done by remote control or mobile phone operation, so that the processor controls the second driver, so that the roller 5 moves the anti-deviation device to a suitable position, so that the laser emitted by the anti-deviation device coincides with the axis of the steel cage 9.

[0049] In the present invention, since the propeller 3 moves up and down on the support rod 1, a structure proposed by the present invention is: a slide groove 2 is opened along the longitudinal direction of the side of the support rod 1 facing the steel cage 9, and a slider 8 is slidably connected to the slide groove 2, and the slider 8 is connected to the propeller 3, and the slider 8 is driven by a third driver to slide up and down on the slide groove 2; the third driver is connected to the processor signal, and the third driver is electrically connected to the power supply.

[0050] It should be stated that the various components of the present invention do not include the steel cage 9. At the same time, the processor also supports external communication, which can be carried out through a remote control or a mobile phone. Through the command of the construction personnel, the processor controls and operates the anti-deviation device of the present invention, thereby enabling the construction personnel to operate the anti-deviation device of the present invention.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent structural change made to the above embodiment based on the technical essence of the present invention still falls within the protection scope of the technical solution of the present invention.
