[0002] Currently, the demand for constructing large-scale equipment test foundations is increasing, and the equipment test foundations have high precision requirements for reserved and embedded components (such as anchor bolts). There are many problems in the construction of embedded parts for equipment foundations. It is difficult to achieve high-precision reinforcement and embedding of embedded parts using traditional reserved and embedded reinforcement methods, especially for precise embedding of embedded parts that are high above the ground.

[0006] Furthermore, the connecting unit includes a connecting steel section with connecting holes; the suspension component is connected to the connecting steel section through the connecting holes.

[0009] Furthermore, the suspension component includes a steel wire rope and an adjustable screw connected to the lower end of the steel wire rope; the upper end of the steel wire rope is connected to the suspension frame, and the adjustable screw is connected to the connecting steel section.

[0015] Furthermore, the H-beam has multiple through holes along its length, and the fixing buckle is connected to the H-beam through the through holes.

[0016] Furthermore, the vertical hoisting device also includes an intelligent power drive device mounted on a horizontal support guide frame, a hook suspended below the intelligent power drive device, vertical support frames mounted at both ends of the horizontal support guide frame, a translation guide rail mounted below the vertical support frame, and a pulley device mounted at the lower end of the vertical support frame and cooperating with the translation guide rail.

[0017] Secondly, the present invention also proposes a method for pre-embedding suspended anchor bolts, comprising the following steps:

[0018] Assemble an anchor bolt assembly; wherein the anchor bolt assembly includes one or more anchor bolt units, and the multiple anchor bolt units are connected by a connecting unit; each anchor bolt unit includes a fastener and one or more anchor bolt bodies mounted on the fastener;

[0019] Install a vertical hoisting device; wherein, the vertical hoisting device includes a horizontal support guide rail frame set above the foundation pit;

[0020] Install an intelligent measurement device; wherein the intelligent measurement device includes a BIM model building module, a laser scanning sensor, and an intelligent camera; install the laser scanning sensor on the connecting unit; install the intelligent camera on the horizontal support guide rail; based on the construction drawings of the anchor bolt assembly, use the BIM model building module to build a BIM model, the BIM model being configured with simulated three-dimensional coordinates of the anchor bolt body, the laser scanning sensor, and the intelligent camera;

[0021] Install a suspension device; wherein the suspension device includes a suspension frame and a plurality of suspension components connected to the suspension frame, the suspension components are connected to the connecting unit, and the suspension frame is set above the foundation pit;

[0022] The anchor bolt assembly and its suspension device above it are hoisted to the target position using the vertical hoisting device, so that the anchor bolt assembly is located in the foundation pit;

[0023] The actual three-dimensional coordinates of the laser scanning sensor are acquired using the smart camera. Based on the deviation between the actual three-dimensional coordinates and the simulated three-dimensional coordinates, the position of the anchor bolt assembly is adjusted so that the difference between the actual position of the laser scanning sensor and the target position of its simulated three-dimensional coordinates is less than or equal to a first preset value.

[0028] The elevation of the anchor bolt body is obtained by scanning with a laser scanning sensor, and then the actual three-dimensional coordinates of each anchor bolt body in the anchor bolt assembly are obtained by a smart camera. This enables a secondary verification of the elevation of the anchor bolt body, thereby improving the elevation control accuracy of the anchor bolt body.

[0029] The beneficial effects of this invention are as follows: By installing the anchor bolt body on the fixing component to form an anchor bolt unit, and then connecting multiple anchor bolt units through a connecting unit, the anchor bolt assembly composed of one or more anchor bolt units is controlled in a suitable pre-embedded position using a suspension device. A BIM model is established through a BIM model building module to determine the simulated three-dimensional coordinates of the anchor bolt body, laser scanning sensor, and smart camera. The actual three-dimensional coordinates of the laser scanning sensor are collected by the smart camera, thereby adjusting the position of the anchor bolt assembly based on the actual position of the laser scanning sensor. Then, each anchor bolt body of the anchor bolt assembly is scanned by the laser scanning sensor to verify the elevation of each anchor bolt body, ensuring the pre-embedded dimensions and accuracy of multiple anchor bolt bodies. This reduces problems such as small working area and inconvenient operation caused by overlapping construction processes. By suspending multiple anchor bolt bodies simultaneously with the fixing component and connecting unit, the overall stability of the anchor bolt body is improved, the installation height is adjustable, and the suspension device is reusable, thereby greatly improving the construction efficiency of the equipment foundation pit, reducing construction costs, and lowering construction difficulty.

[0041] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] like Figure 1-6 The suspended anchor bolt pre-embedded fixing device shown includes an anchor bolt assembly 1, a suspension device 2, an intelligent measuring device 3, and a vertical hoisting device 4.

[0043] like Figure 2 As shown, the vertical hoisting device 4 includes a horizontal support guide rail frame 46 positioned above the anchor bolt assembly 1, an intelligent power drive device 48 mounted on the horizontal support guide rail frame 46, a hook 47 suspended below the intelligent power drive device 48, vertical support frames 45 positioned at both ends of the horizontal support guide rail frame 46, a base 44 positioned at the lower end of the vertical support frame 45, a pulley device 43 positioned at the lower end of the base 44, a limiting device 42 positioned at the end of the base 44, and a translational guide rail 41 positioned below the base 44. The pulley device 43 cooperates with the translational guide rail 41, and under the action of the pulley device 43, drives the base 44 to move along the length direction of the translational guide rail 41, thereby driving the vertical support frame 45 on the base 44 and the horizontal support guide rail frame 46 connected to the vertical support frame 45 to translate. The limiting device 42 can restrict the movement of the pulley device 43 on the translational guide rail 41, and the limiting device 42 can adopt existing technology. The intelligent power drive device 48 can move along the length of the horizontal support guide rail 46 to adjust the position of the hook 47 below it and drive the hook 47 to rise and fall, so as to realize the transfer of the anchor bolt assembly 1 and the initial elevation control. In particular, it can realize that the anchor bolt assembly 1 is in the pit but does not contact the bottom of the pit and remains suspended.

[0044] like Figure 3 As shown, the anchor bolt assembly 1 includes four anchor bolt units. In some embodiments, the anchor bolt assembly 1 may include only one anchor bolt unit, or may include other numbers of anchor bolt units.

[0045] like Figure 3 The four anchor bolt units shown are arranged in a 2x2 array. Two horizontally adjacent anchor bolt units are connected by connecting units, and two vertically adjacent anchor bolt units are also connected by connecting units. In other words, this embodiment has four connecting units. The four connecting units and the four anchor bolt units are sequentially and alternately connected to form a closed ring structure.

[0046] In this embodiment, the connecting unit includes connecting steel profiles 14, each with connecting holes 16. There are four connecting steel profiles 14, which are alternately connected to four anchor bolt units. At least two parallel connecting steel profiles 14 are each provided with a connecting hole 16.

[0047] like Figure 3 As shown, the four connecting steel sections 14 include two parallel transverse connecting steel sections 14 and two parallel longitudinal connecting steel sections 14. Connecting holes 16 are respectively provided on the two parallel longitudinal connecting steel sections 14.

[0048] To further improve the stability of the anchor bolt assembly 1, the connecting unit also includes a cross steel section 15, which connects two parallel connecting steel sections 14. The two ends of the cross steel section 15 are connected to the two parallel transverse connecting steel sections 14. In this embodiment, the connection method between the connecting steel sections 14 and the cross steel section 15 is preferably welding. In subsequent connections, welding is preferred. A positioning point is provided at the intersection center point of the cross steel section 15.

[0049] Each anchor bolt unit includes a fastener and one or more anchor bolt bodies 11 mounted on the fastener.

[0050] like Figure 3 As shown, each anchor bolt unit includes a fastener, which has a rectangular frame structure. The fastener includes four fixing channel steels 12 and four intersecting steel plates 13. The four fixing channel steels 12 are connected end-to-end to form a closed rectangular ring frame structure. The intersecting steel plates 13 are located on the inner side of this rectangular ring frame structure. The intersecting steel plates 13 have four connecting ends, which are respectively connected to the four inner corners of the rectangular ring frame structure. The four fixing channel steels 12 include two parallel transverse fixing channel steels 12 and two parallel longitudinal fixing channel steels 12.

[0051] One or more anchor bolt bodies 11 are installed on each fixed channel steel 12.

[0052] like Figure 4 , Figure 5As shown, the anchor bolt body 11 includes a bolt member 111 suspended on a fixed channel steel 12 and a fixing nut 112 that is threadedly engaged with the bolt member 111 and located at the upper end of the fixed channel steel 12. There are two fixing nuts 112. By rotating the fixing nut 112, the engagement depth between it and the bolt member 111 is adjusted, thereby adjusting the relative height between the bolt member 111 and the fixed channel steel 12, and thus adjusting the pre-embedding depth of the anchor bolt body 11.

[0053] The suspension device 2 includes a suspension frame 21 and multiple suspension components connected to the suspension frame 21. The suspension components are connected to the connecting steel profile 14 of the connecting unit.

[0054] The suspension bracket 21 includes an H-beam, on which a fixing buckle 22 is provided, which connects to the suspension component. To facilitate adjustment of the position of the fixing buckle 22 and the suspension component, multiple through holes are provided on the H-beam along its length, and the fixing buckle 22 is connected to the H-beam through the through holes.

[0055] like Figure 4 and Figure 6 As shown, the suspension component includes a steel wire rope 23 and an adjustable screw 24 connected to the lower end of the steel wire rope 23; the upper end of the steel wire rope 23 is connected to a fixing buckle 22, which is connected to the suspension frame 21; the adjustable screw 24 is connected to the connecting steel profile 14.

[0056] Specifically, the adjustable screw 24 includes a telescopic rod 242 and a telescopic housing 243. The lower end of the telescopic rod 242 passes through the connecting hole 16 of the connecting steel profile 14. After passing through the connecting steel profile 14, the lower end of the telescopic rod 242 is connected to an eye bolt 25, which is located at the lower end of the connecting steel profile 14. The eye bolt 25 can also be replaced by a nut, the diameter of which is larger than the diameter of the connecting hole 16 of the connecting steel profile 14. The upper end of the telescopic rod 242 is located inside the telescopic housing 243, and the upper end of the telescopic housing 243 is connected to the wire rope 23.

[0057] The adjustable screw 24 also includes a limiter 241, which is mounted on the telescopic rod 242. The limiter 241 restricts the displacement range of the telescopic rod 242 or the telescopic housing 243. The telescopic rod 242 and the telescopic housing 243 are threaded together. Rotating the telescopic housing 243 adjusts the depth of the threaded engagement with the telescopic rod 242, thereby adjusting the distance between the wire rope 23 and the connecting steel section 14, thus achieving height adjustment of the connecting steel section 14. The limiter 241 restricts the upward movement height of the telescopic housing 243.

[0058] The adjustable screw 24 can also adopt the principle of an electric telescopic rod or other existing conventional telescopic structures.

[0059] The height adjustment of the aforementioned anchor bolt assembly 1 can be performed manually, while the monitoring of the adjustment accuracy and whether the height is at the target height are achieved by the intelligent measuring device of this embodiment.

[0060] like Figure 1 As shown, the intelligent measurement device 3 includes a BIM model building module with phase data connectivity, a laser scanning sensor 31, and an intelligent camera 32.

[0061] The BIM model building module creates a BIM model based on the construction drawings of the anchor bolt assembly. The BIM model is configured with simulated three-dimensional coordinates of the anchor bolt body, laser scanning sensor 31, and smart camera 32. The method of creating the BIM model and configuring the simulated three-dimensional coordinates can be achieved using existing technologies. The BIM model is also configured with simulated three-dimensional coordinates of the positioning points of the intersection center points of the fork-shaped steel 15.

[0062] The laser scanning sensor 31 is disposed on the connecting unit, for example, the laser scanning sensor 31 is disposed at the center of the upper end face of the connecting steel 14. In this embodiment, each anchor bolt assembly 1 is provided with at least two laser scanning sensors 31, and each of the two parallel longitudinal connecting steel 14 of the anchor bolt assembly 1 is provided with two connecting holes 16 and one laser scanning sensor 31, that is, each longitudinal connecting steel 14 is provided with two connecting holes 16 and a laser scanning sensor 31 disposed between the two connecting holes 16.

[0063] like Figure 2 As shown, there are two smart cameras 32 mounted on a horizontal support rail frame 46, with the latter positioned at a distance from the former.

[0064] In some embodiments, the laser scanning sensor 31 and the smart camera 32 can also be connected to the smart power drive device 48 of the vertical hoisting device 4, and the smart power drive device 48 can also be connected to the pulley device 43. Based on the feedback signals from the laser scanning sensor 31 and the smart camera 32, the smart power drive device 48 controls the height of the hook 47, the position of the smart power drive device 48 on the horizontal support guide rail 46, and the position of the pulley device 43 on the translation guide rail 41.

[0065] The intelligent camera 32 acquires the actual three-dimensional coordinates of the laser scanning sensor 31. Based on the deviation between the actual three-dimensional coordinates and the simulated three-dimensional coordinates, the position of the anchor bolt assembly 1 is adjusted so that the difference between the actual position of the laser scanning sensor 31 and the target position of its simulated three-dimensional coordinates is less than or equal to a first preset value.

[0066] In some embodiments, the laser scanning sensor 31 is pre-fixed on the anchor bolt assembly 1. The intelligent camera 32 collects the actual three-dimensional coordinates of the positioning point of the intersection center point of the intersecting steel sections 15 of the anchor bolt assembly, and transmits the data to the BIM model building module. The BIM model building module compares the actual three-dimensional coordinates of the positioning point with the simulated three-dimensional coordinates of the positioning point. When the difference between the two is greater than a first preset value, the position of the anchor bolt assembly 1 is manually adjusted or adjusted using a vertical hoisting device so that the difference between the actual position of the laser scanning sensor 31 and the target position of its simulated three-dimensional coordinates is less than or equal to the first preset value. When adjusting the position of the anchor bolt assembly 1, its horizontal position is adjusted first, and then its height is adjusted.

[0067] The laser scanning sensor 31 scans each anchor bolt body 11 of the anchor bolt assembly 1 to obtain the actual three-dimensional coordinates of each anchor bolt body 11. Based on the deviation between its actual three-dimensional coordinates and simulated three-dimensional coordinates, the height of each anchor bolt body 11 is adjusted so that the difference between the actual height of each anchor bolt body 11 and the target height of its simulated three-dimensional coordinates is less than or equal to a second preset value.

[0068] The intelligent camera 32 can also obtain the actual three-dimensional coordinates of each anchor bolt body of the anchor bolt assembly 1 through image deep learning. Based on the deviation between its actual three-dimensional coordinates and simulated three-dimensional coordinates, the height of each anchor bolt body is adjusted so that the difference between the actual height of each anchor bolt body 11 and the target height of its simulated three-dimensional coordinates is less than or equal to a second preset value. The second preset value is preferably ±0.5mm.

[0069] The intelligent camera 32 first measures the position of the laser scanning sensor 31 to ensure that the position of the laser scanning sensor 31 is consistent with the position given in the construction drawings. After the position of the laser scanning sensor 31 is determined, the laser scanning sensor 31 scans each anchor bolt body 11 360° to obtain the actual three-dimensional coordinates of each anchor bolt body 11 and transmits the data to the BIM model construction module. The BIM model construction module compares the actual three-dimensional coordinates of each anchor bolt body 11 with the simulated three-dimensional coordinates. When the difference between the two is greater than a second preset value, the height of the anchor bolt body 11 is marked as not meeting the requirements. Construction personnel adjust the height of the corresponding anchor bolt body 11 according to the mark and use the laser scanning sensor 31 to obtain the adjusted actual three-dimensional coordinates of the anchor bolt body 11 again until the difference between the actual height of the anchor bolt body 11 and the target height of its simulated three-dimensional coordinates is less than or equal to the second preset value. Then, the elevation of the anchor bolt body 11 is considered to meet the requirements.

[0070] Similarly, the smart camera 32 can also obtain the actual three-dimensional coordinates of each anchor bolt body 11 of the anchor bolt assembly 1 based on image deep learning, and transmit the data to the BIM model building module. The BIM model building module verifies the elevation of each anchor bolt body 11.

[0071] The laser scanning sensor 31 can generate 3D point cloud data or other forms of images based on the scanning and measurement results of the laser beam. The smart camera 32 can generate a 3D model of an object or the actual 3D coordinates of a scene based on the depth image or point cloud data.

[0072] When using the device of this embodiment to carry out the pre-embedding construction of the anchor bolt body 11, the following steps are included: first assembling the anchor bolt unit, and then assembling multiple anchor bolt units to form the anchor bolt assembly 1; during the assembly process, ensuring that the position of the anchor bolt body 11 is consistent with the relative position on the drawing.

[0073] The suspension frame 21 is installed above the foundation pit, and the anchor bolt assembly 1 and the suspension frame 21 are connected by the suspension component, so that the anchor bolt assembly 1 is suspended in the foundation pit.

[0074] The elevation of the anchor bolt body 11 is verified by an intelligent measuring device, and the height of the anchor bolt assembly 1 is adjusted by an adjustable screw 24 to achieve the elevation adjustment of the anchor bolt body 11.

[0075] Before the foundation pit is poured with concrete to embed the anchor bolt body 11, a steel mesh is prepared and then connected to the anchor bolt body 11.

[0076] Pouring concrete for the foundation pit.

[0077] The method for pre-embedding suspended anchor bolts in this embodiment specifically includes the following steps:

[0078] Assemble an anchor bolt assembly; wherein the anchor bolt assembly includes one or more anchor bolt units, and the multiple anchor bolt units are connected by a connecting unit; each anchor bolt unit includes a fastener and one or more anchor bolt bodies mounted on the fastener;

[0079] Install a vertical hoisting device; wherein, the vertical hoisting device includes a horizontal support guide rail frame set above the foundation pit;

[0080] Install an intelligent measurement device; the intelligent measurement device includes a BIM model building module, a laser scanning sensor, and an intelligent camera; install the laser scanning sensor on the connection unit; install the intelligent camera on the horizontal support guide rail; based on the construction drawings of the anchor bolt assembly, use the BIM model building module to build a BIM model, the BIM model is configured with simulated three-dimensional coordinates of the anchor bolt body, laser scanning sensor, and intelligent camera;

[0081] Install a suspension device; wherein the suspension device includes a suspension frame and multiple suspension components connected to the suspension frame, connect the suspension components to the connecting unit, and set the suspension frame above the foundation pit;

[0082] The anchor bolt assembly and its suspension device above it are hoisted to the target position using a vertical hoisting device, so that the anchor bolt assembly is located inside the foundation pit;

[0083] The actual three-dimensional coordinates of the laser scanning sensor are collected by a smart camera. Based on the deviation between the actual three-dimensional coordinates and the simulated three-dimensional coordinates, the position of the anchor bolt assembly is adjusted so that the difference between the actual position of the laser scanning sensor and the target position of its simulated three-dimensional coordinates is less than or equal to a first preset value.

[0084] Using a laser scanning sensor, each anchor bolt body of the anchor bolt assembly is scanned to obtain the actual three-dimensional coordinates of each anchor bolt body. Based on the deviation between its actual three-dimensional coordinates and simulated three-dimensional coordinates, the height of each anchor bolt body is adjusted so that the difference between the actual height of each anchor bolt body and the target height of its simulated three-dimensional coordinates is less than or equal to a second preset value.

[0085] Using a smart camera, the actual three-dimensional coordinates of each anchor bolt body in the anchor bolt assembly are obtained through image deep learning; based on the deviation between its actual three-dimensional coordinates and simulated three-dimensional coordinates, the height of each anchor bolt body is adjusted so that the difference between the actual height of each anchor bolt body and the target height of its simulated three-dimensional coordinates is less than or equal to a second preset value.

[0086] When the difference between the actual height of each anchor bolt body scanned by the laser scanning sensor and the actual height of the corresponding anchor bolt body obtained by the smart camera is less than or equal to the third preset value, proceed to the next step;

[0087] Prepare the reinforcing mesh and connect it to the anchor bolt assembly;

[0088] The foundation pit concrete is poured in two stages. The first pour secures the lower part of the anchor bolt body 11, primarily fixing the portion of the anchor bolt body 11 below the fixing channel steel 12, thus pre-fixing the anchor bolt body 11. After the anchor bolt body 11 is pre-fixed, the anchor bolt assembly 1 is also initially fixed. The connection between the suspension component and the connecting unit is then released to allow for the reuse of the suspension device 2. The second pour is then performed, pouring concrete to the design elevation. After each pour, thorough vibration and mixing are required. The concrete used should have a micro-expansion properties or be one grade higher than the concrete used for the foundation. Figure 4As shown, the second concrete pour is just above the upper end of the fixed channel steel 12, thus pre-embedding the anchor bolt assembly 1 as a whole. The anchor bolt assembly 1 can be regarded as a pre-embedded part of the foundation pit.
