Description

Technical Field

[0001] The invention relates to an anchor bolt installation detection device, in particular to an anchor bolt installation detection device applied in the field of measuring devices. Background Art

[0002] When mechanical components are installed on a concrete foundation, the J-shaped or L-shaped end of the bolt is buried in the concrete. The tensile strength of the anchor bolt is the tensile strength of the round steel itself, which is equal to the cross-sectional area multiplied by the allowable stress value, which is the allowable tensile bearing capacity during design.

[0003] There are two main ways to install anchor bolts. The first is the one-time embedding method: embed the anchor bolts when pouring concrete. The second is the reserved hole method: put the equipment in place, clean the holes, put the anchor bolts into the holes, position and align the equipment, and then pour with non-shrinkage fine stone concrete that is one level higher than the original foundation and tamp it to make it dense.

[0004] In the above two installation methods, the anchor bolts are fixed by pouring concrete. During actual installation, the bolts need to be placed vertically at the target position and then the concrete is poured. However, due to the impact of the concrete material and the instability of the bottom of the anchor bolts, the anchor bolts are often prone to tilt during pouring. When the tilt is large, it can be adjusted in time, but when the tilt is small, it is difficult to detect. When the concrete solidifies, it is completely restricted and difficult to adjust. When the equipment is installed later, it is easy to cause difficulty in assembly. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that tilting is easy to occur during pouring, and a slight tilt is easy to affect the normal installation of subsequent equipment.

[0006] In order to solve the above problems, the present invention provides a foundation bolt installation detection device, comprising two detection platforms, two limit long rods are inserted between the two detection platforms, one detection platform is fixedly penetrated by the two limit long rods, and the other detection platform is movably penetrated by the two limit long rods, the left and right ends of the detection platform are fixedly connected with self-test plates, a telescopic cylinder is installed between the two opposite self-test plates, and the lower end of the self-test plate is fixedly connected with a telescopic leg;

[0007] A bolt groove is chiseled in the middle of the bottom surface of the testing table, an inspection groove is chiseled in the middle of the upper end of the testing table, an outer shielding plate is clamped at the mouth of the inspection groove, the upper middle part of the outer shielding plate and the outer surface of the limiting long rod are engraved with scales, a magnetically controlled pressure bar is fixedly connected to the inside of the inspection groove, a color-changing strip is fixedly connected to the center of the bottom of the inspection groove, and the color-changing strip is located directly below the magnetically controlled pressure bar. Two sets of positioning components are also provided at the bottom of the testing table, the positioning components include a fixed plate fixedly connected to the bottom edge of the testing table, a moving plate located outside the bolt groove, and a pair of electric push rods connected between the fixed plate and the moving plate, and the extended ends of the electric push rods are connected to the moving plate.

[0008] In the above-mentioned anchor bolt installation and measuring device, on the one hand, the anchor bolts can be stabilized and limited to assist in installation, and on the other hand, whether the anchor bolts are tilted can be detected simultaneously, so that adjustments can be made in time when slight tilt occurs, effectively ensuring the accuracy of the anchor bolt installation and facilitating the accurate installation of subsequent equipment.

[0009] As a further improvement of the present application, self-test grooves are bored at the upper ends of two self-test plates which are arranged at opposite angles, and a self-test leveling assembly is arranged in the self-test grooves. The self-test leveling assembly includes a self-testing iron ball placed in the self-test grooves, a cover plate clamped in the mouth of the self-test grooves, a magnetic breaking piece fixedly embedded in the inside of the self-test plate, and a ball-guiding magnetic plate slidably connected to the bottom of the self-test plate.

[0010] As a further improvement of the present application, the narrow side span of the self-testing groove is larger than the diameter of the self-testing iron ball, the cover plate and the outer shield are both transparent structures, the magnetic breaking sheet is made of magnetic shielding material, there is a magnetic attraction between the ball attracting magnetic plate and the self-testing iron ball, and the left and right span of the ball attracting magnetic plate is larger than the diameter of the self-testing iron ball and smaller than the left and right span of the magnetic breaking sheet.

[0011] As a further improvement of the present application, the length of the detection groove is greater than the lateral length of the bolt groove, the width of the detection groove is also greater than the span of the bolt groove, and the width of the detection groove is not less than twice the width of the bolt groove.

[0012] As a further improvement of the present application, the magnetically controlled pressure row includes a plurality of evenly distributed automatic pressure sheets, which include a near-strip sheet and two control ropes fixedly connected at both ends of the near-strip sheet, the ends of the two control ropes away from the near-strip sheet are respectively fixedly connected to the inner walls of the detection groove, the near-strip sheet is a magnetically transparent structure, the control rope is an elastic structure, and when the control rope is fully extended, the near-strip sheet does not contact the color-changing strip.

[0013] As a further improvement of the present application, the color-changing strip is directly opposite to the middle of the plurality of proximal strip pieces, and is an elastic transparent structure filled with a color solution, and the upward cross-section of the color-changing strip is an arc larger than a semicircle.

[0014] As another improvement of the present application, the color-changing strip is a hollow hard structure with a semicircular cross-section, and the interior of the color-changing strip is saturated with a magnetic mixed liquid, which is a mixture of iron powder and clean water in a volume ratio of 1:10-20, and a waterproof colored coating is adhered to the surface of the iron powder.

[0015] As another improved supplement of the present application, the left and right ends of the color-changing strip are respectively fixedly connected with air guide tubes, and the two air guide tubes are fixedly passed through the detection platform and extend to the top of the detection platform.

[0016] In summary, during installation, according to the relative positions of multiple anchor bolts, multiple anchor bolts can be directly inserted into the bolt slots and the relative positions and distances can be directly measured and adjusted. At the same time, due to the magnetic force, the automatic pressing plate at the corresponding position moves toward the color-changing strip. On the one hand, the anchor bolts can be magnetically positioned to assist in pouring concrete and fixing multiple anchor bolts at the same time. On the other hand, when pouring concrete, it can be clearly observed on the surface of the test bench that there is obvious color aggregation at the color-changing strip. After a significant tilt occurs, the color aggregation phenomenon will be significantly weakened. In this way, it is possible to detect whether the anchor bolts are tilted, which is convenient for the staff to make timely adjustments when a slight tilt occurs, effectively ensuring the accuracy of the installation of the anchor bolts and facilitating the accurate installation of subsequent equipment.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1 A foundation bolt installation detection device is shown, comprising two detection platforms 1, two limit long rods 3 are penetrated between the two detection platforms 1, and the limit long rods 3 prevent the two detection platforms 1 from shifting left and right when the relative positions are changed. One detection platform 1 is fixedly penetrated by the two limit long rods 3, and the other detection platform 1 is movably penetrated by the two limit long rods 3, so that one of the two detection platforms 1 is in a fixed state and the other is in a movable state. The left and right ends of the detection platforms 1 are fixedly connected with self-test plates 2, and a telescopic cylinder 42 is installed between the two opposite self-test plates 2. The lower end of the self-test plate 2 is fixedly connected with a telescopic leg 41. When in use, the height of the detection platform 1 can be adjusted according to the actual spacing requirements when multiple anchor bolts are installed, and the distance between the two detection platforms 1 is adjusted by the telescopic cylinder 42, so that the movable detection platform 1 can be moved along the limit long rods 3, such as Figure 2 It is the state when the distance between the two test platforms 1 is the smallest. In addition, the outer surface of the limit rod 3 is engraved with scales, so that the distance between the two test platforms 1 can be visually seen, which is convenient for controlling and measuring the relative position and distance between multiple anchor bolts;

[0033] like Figure 3 and Figure 4In the figure, a represents an anchor bolt. A bolt groove 101 is cut in the middle of the bottom surface of the test platform 1, and a test groove 102 is cut in the middle of the upper end of the test platform 1. An outer shielding plate 103 is clamped at the mouth of the test groove 102. A scale is engraved in the middle of the upper end of the outer shielding plate 103, so that after the anchor bolt is inserted into the bolt groove 101, the position of the anchor bolt can be visually seen, and the distance and relative position between the anchor bolts and other anchor bolts can be directly measured by the scale, which is convenient for installation. A magnetic control pressure row 6 is also fixedly connected inside the test groove 102. The bottom of the test platform 1 Two sets of positioning components are also provided, which include a fixed plate 51 fixedly connected to the bottom edge of the inspection platform 1, a movable plate 53 located outside the mouth of the bolt groove 101, and a pair of electric push rods 52 connected between the fixed plate 51 and the movable plate 53. The extended end of the electric push rod 52 is connected to the movable plate 53. After the anchor bolt is inserted into the bolt groove 101, the movable plate 53 can be controlled by the electric push rod 52 to move toward the anchor bolt, so that the anchor bolt can be resisted by the two movable plates 53, thereby being temporarily limited, so that it is not easy to tilt during pouring.

[0034] It is worth noting that in order to improve the stability of the movable plate 53 when squeezing the anchor bolt, a rubber layer can be attached to the opposite end faces of the two movable plates 53. When in conflict, the rubber layer can be deformed and contact the surface of the anchor bolt, thereby increasing the contact area between the rubber layer and the anchor bolt, making the effect of limiting the anchor bolt better and more stable.

[0035] The length of the detection groove 102 is greater than the lateral length of the bolt groove 101, the width of the detection groove 102 is also greater than the span of the bolt groove 101, and the width of the detection groove 102 is not less than twice the width of the bolt groove 101. After the anchor bolt is inserted into the bolt groove 101, due to its magnetism, it can fully attract the automatic pressing plate on the magnetically controlled pressure row 6 to move toward the color-changing strip 7, and it is not easy for the upper end of the anchor bolt to have no corresponding automatic pressing plate.

[0036] like Figure 5 A color-changing strip 7 is fixedly connected to the center of the bottom of the detection slot 102, and the color-changing strip 7 is located directly below the magnetic control pressure row 6. Figure 6 The magnetically controlled pressure row 6 includes a plurality of evenly distributed automatic pressure sheets, which include a near-strip sheet 61 and two control ropes 62 fixedly connected to both ends of the near-strip sheet 61. The ends of the two control ropes 62 away from the near-strip sheet 61 are respectively fixedly connected to the inner walls of the detection groove 102. The near-strip sheet 61 is a magnetically transparent structure, so that after the anchor bolt is inserted into the bolt groove 101, a magnetic attraction force can be stably generated between it and the anchor bolt. Since it is difficult for the anchor bolt to continue to approach the magnetically controlled pressure row 6, the corresponding near-strip sheet 61 is passively moved toward the color-changing strip 7 under the action of the magnetic attraction force, and squeezes the color-changing strip 7 to deform the color-changing strip 7. The control rope 62 is an elastic structure, and when the control rope 62 is fully extended, the near-strip sheet 61 does not contact the color-changing strip 7.

[0037] The color-changing strip 7 is directly opposite to the middle of the plurality of proximal strips 61, and the color-changing strip 7 is an elastic transparent structure filled with a color solution. The cross section of the color-changing strip 7 facing upward is an arc greater than a semicircle. After the anchor bolts are inserted, Figure 7 and Figure 8 , there is magnetic attraction, the proximal strip 61 moves downward to squeeze the color-adaptive strip 7, causing it to deform significantly, and the cross-section at the corresponding position becomes significantly larger. After the anchor bolt tilts, an angle is generated between the end of the anchor bolt and the top of the bolt slot 101, resulting in a certain change in the adsorption force on the proximal strip 61. At this time, the deformation of the color-adaptive strip 7 will be reduced to a certain extent.

[0038] The above deformation workers can observe directly with the naked eye. To improve intelligence, a high-definition camera and an alarm can also be installed on the top of the detection platform 1. After the anchor bolt is stably inserted, the deformation image information at the color-variable strip 7 is obtained. During subsequent pouring, the image changes at this location are continuously monitored. When the image changes significantly, the alarm can sound an alarm to remind the anchor bolt to tilt. This is an optional setting, and you can choose whether to set a high-definition camera and an alarm according to actual needs.

[0039] like Fig. 9 , wherein the upper ends of the two obliquely opposite self-test plates 2 are bored with self-test grooves, and a self-test leveling component is arranged in the self-test groove, and the self-test leveling component includes a self-test iron ball 22 placed in the self-test groove, a cover plate 21 clamped in the self-test groove, a magnetic breaking piece 23 fixedly embedded in the self-test plate 2, and a ball-attracting magnetic plate 24 slidably connected to the bottom of the self-test plate 2, the narrow side span of the self-test groove is greater than the diameter of the self-test iron ball 22, the cover plate 21 and the outer shielding plate 103 are both transparent structures, the magnetic breaking piece 23 is made of magnetic shielding material, there is a magnetic attraction between the ball-attracting magnetic plate 24 and the self-test iron ball 22, and the left and right spans of the ball-attracting magnetic plate 24 are greater than the diameter of the self-test iron ball 22 and smaller than the left and right spans of the magnetic breaking piece 23, and the anchor bolts Before installation, it is necessary to adjust the overall level of the detection table 1. After placing it, slide the ball-guiding magnetic plate 24 to make it opposite to the self-testing iron ball 22 and generate adsorption force on the self-testing iron ball 22. Then continue to move the ball-guiding magnetic plate 24 to make it move with the self-testing iron ball 22. The ball-guiding magnetic plate 24 is installed to cross the magnetic breaking plate 23. When crossing the magnetic breaking plate 23, due to the magnetic shielding property of the magnetic breaking plate 23, the temporary restraint between the self-testing iron ball 22 and the ball-guiding magnetic plate 24 is released. When the self-testing iron ball 22 stops stably at the magnetic breaking plate 23, it indicates that the entire measuring device is level. If it rolls to one side of the self-testing slot, it indicates that the whole is not level, and the side to which the self-testing iron ball 22 rolls is lower on the corresponding side.

[0040] In summary, during installation, according to the relative positions of multiple anchor bolts, multiple anchor bolts can be directly inserted into the bolt groove 101 and the relative positions and distances can be directly measured and adjusted. At the same time, due to the magnetic force, the automatic pressing plate at the corresponding position moves toward the color-variable strip 7. On the one hand, the anchor bolts can be magnetically positioned, which can assist in pouring concrete and fixing multiple anchor bolts at the same time. On the other hand, when pouring concrete, it can be clearly observed on the surface of the test bench 1 that there is an obvious color aggregation phenomenon at the color-variable strip 7. After a significant tilt occurs, the color aggregation phenomenon will be significantly weakened, and it can be realized to detect whether the anchor bolt is tilted, which is convenient for the staff to make timely adjustments when a slight tilt occurs, effectively ensuring the accuracy of the installation of the anchor bolts, and facilitating the accurate installation of subsequent equipment.

[0041] The second implementation method:

[0042] This embodiment is based on the first embodiment, and the specific arrangement of the color-adaptive strip 7 is changed, while the rest is consistent with the first embodiment.

[0043] Fig.10 and Fig.11 As shown, the left and right ends of the color-changing strip 7 are respectively fixedly connected with air guide tubes 701, and the two air guide tubes 701 are fixedly passed through the detection platform 1 and extend to the top of the detection platform 1. The color-changing strip 7 is a hollow hard structure with a semicircular cross-section, and the interior of the color-changing strip 7 is saturated with a magnetic mixed liquid, which is a mixture of iron powder and clean water in a volume ratio of 1:10-20, and a waterproof colored coating is adhered to the surface of the iron powder.

[0044] In this embodiment, after the anchor bolt is inserted, the corresponding proximal strip piece 61 approaches the color-changing strip 7 and contacts the surface of the color-changing strip 7, so that the iron powder at this location is bound. At the same time, the air guide tubes 701 on both sides can be alternately filled and discharged to make the magnetic mixed liquid dynamic. Part of the iron powder continues to approach this location, so that the amount of magnetic powder bound is significantly increased. After tilting, the corresponding proximal strip piece 61 is also tilted, so that the adsorption force on the iron powder becomes smaller. In conjunction with the operation of filling and sucking air, part of the gathered iron powder will be dispersed, so that the range and amount of iron powder gathering will be reduced accordingly, and then a significant change will occur, thereby achieving the effect of reminding the staff and making the installation inspection of the anchor bolts better.

[0045] Specifically, the sealing airbags can be fixedly connected at the mouths of the two air guide tubes 701, and then the sealing airbags are pushed back and forth by an electric push rod, and the two sealing airbags are not squeezed at the same time, so that airflow impacts the two sides continuously and alternately, so that the iron powder is in a dynamic and continuously reorganized state in the color-changing strip 7, so that the gathered iron powder can be obviously changed after the anchor bolt is tilted.

[0046] Similarly, in order to improve intelligence, a high-definition camera and an alarm may be installed on the top of the testing platform 1 to capture the changes in the aggregation and dispersion of the iron powder.

[0047] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
