[0035] Please refer to Figures 1-5 An embodiment of the present application is: a precise installation device for embedded parts, comprising an embedded assembly 1 and a support frame 2. The embedded assembly 1 comprises an embedded plate, an anchor bar and a hollow plate. The anchor bar is fixedly installed at the bottom of the embedded plate, and the hollow plate is fixedly installed at the bottom of the embedded plate. The surface of the support frame 2 is fixedly installed with an electric telescopic rod 3. The output end of the electric telescopic rod 3 is fixedly installed with a platform 4.

The adjusting device comprises an electric push rod 5 and a rotating wheel 6. The electric push rod 5 is fixedly installed at the top of the platform 4. The rotating wheel 6 is rotatably installed on the circumferential surface of the output end of the electric push rod 5. The top of the platform 4 is provided with a carrying plate 7. The bottom of the carrying plate 7 is fixedly installed with a groove-shaped plate 8. The rotating wheel 6 is in contact with the inner wall of the groove-shaped plate 8. The carrying plate 7 is fixedly connected with the embedded plate through bolts. Through the design of the rotating wheel 6 and the groove-shaped plate 8, the carrying plate 7 can be flexibly adjusted in the horizontal plane, which not only greatly reduces the time and intensity of manual operation, but also effectively improves the construction efficiency.

The pressure sensor is used to monitor the stress of the embedded assembly 1 during installation. By arranging the positioning device 9 in the embedded assembly 1, the efficiency of position adjustment can be effectively improved.

[0037] The surface of the positioning device 9 is provided with a sensing end. A I-shaped bar 10 is slidably penetrated through the outer wall of the hollow plate. The side of the I-shaped bar 10 away from the anchor bar is in contact with the sensing end. The sensing end is used to transmit the pressure received by the I-shaped bar 10 to the inside of the pressure sensor. By monitoring the pressure in real time and adjusting the position slightly, the embedded assembly 1 can be more fitted to the pouring form of the concrete, thereby improving the stability of the overall structure.

[0038] A gantry 21 is arranged around the support frame 2. A plurality of laser measuring instruments 22 are arranged on the surface of the gantry 21.

The high-precision data provided by the laser measuring instruments 22 provides a scientific basis for the installation and adjustment of the embedded assembly 1, avoiding subjective errors in manual measurement.

[0039] A construction method of a precise installation device of a pre-embedded part, comprising the following steps:

[0040] Step one: set up a high-precision total station of Beidou satellite positioning system at the construction site, use the total station to measure the terrain of the construction site, obtain detailed terrain data, import the data into computer-aided design software, combine with engineering design drawings, and establish a three-dimensional model of the construction site;

[0041] Step two: preliminarily process and assemble the pre-embedded component 1, and install the positioning device 9 with a positioning chip and a pressure sensor on the pre-embedded component 1, then transport the pre-embedded component 1 to the construction site, use the hoisting equipment with automatic positioning and adjustment function to hoist, the hoisting equipment hoists the pre-embedded component 1 to the installation position, and automatically adjusts the position and elevation of the pre-embedded component 1 according to the deviation data fed back by the positioning system, so that it preliminarily approaches the design position;

[0042] Step three: adjust the elevation and horizontal position of the pre-embedded component 1 through the electric telescopic rod 3 and the electric push rod 5 to preliminarily position, after the preliminary positioning is completed, use the high-precision laser measuring instrument 22 to accurately measure the position and elevation of the pre-embedded component 1;

[0043] Step four: when the deviation meets the design requirements, the construction worker pours concrete, the positioning device 9 monitors the position and elevation change of the pre-embedded component 1 in real time during the pouring process, once the deviation exceeds the preset threshold, the system immediately issues an alarm, the construction worker adjusts the pre-embedded component 1 through the electric telescopic rod 3 and the electric push rod 5 to ensure that the pre-embedded component 1 always maintains accurate position and elevation before the concrete solidifies.

[0044] In operation, the construction worker first builds a rectangular formwork below the embedded assembly 1 to prepare for subsequent concrete pouring, and then starts the electric telescopic rod 3, the output end of which drives the platform 4 to descend, and the platform 4 drives the electric push rod 5 and the rotating wheel 6 to descend as a whole, and the rotating wheel 6 drives the loading plate 7 to descend synchronously through the slot-shaped plate 8, and the loading plate 7 further drives the embedded assembly 1 to descend, and in the descending process, the positioning device 9 inside the embedded assembly 1 obtains position information in real time to ensure that the embedded assembly 1 can accurately reach the predetermined elevation position; after the height adjustment is completed, the horizontal direction adjustment stage of the embedded assembly 1 is entered, and when it is necessary to move the embedded assembly 1 to the right side, with the platform 4 as a reference, the left electric push rod 5 drives the rotating wheel 6 to move to the right side, and the right electric push rod 5 synchronously drives the rotating wheel 6 to move to the right side, so that the loading plate 7 and the slot-shaped plate 8 move to the right side as a whole, and the loading plate 7 drives the embedded assembly 1 to move synchronously in the moving process; when the slot-shaped plate 8 moves to the right side, the front and rear electric push rods 5 remain stationary, so that a frictional force is generated between the slot-shaped plate 8 and the front and rear rotating wheels 6, and the front and rear rotating wheels 6 rotate under the action of the frictional force to assist the loading plate 7 to move stably, and through the design of the rotating wheel 6 and the slot-shaped plate 8, the loading plate 7 can be flexibly adjusted on the horizontal plane, which not only greatly reduces the time and intensity of manual operation, but also effectively improves the construction efficiency and shortens the engineering period;

[0045] After the preliminary positioning is completed, the construction worker starts the laser measuring instrument 22, and the high-precision laser measuring instrument 22 accurately measures the position and elevation of the embedded assembly 1, and in the measuring process, the laser measuring instrument 22 scans the surface of the embedded assembly 1 to obtain the actual position and elevation data, and compares these data with the design data; if it is found that there is a deviation after comparison, the system automatically calculates the adjustment amount, and the construction worker adjusts the height of the embedded assembly 1 by starting the electric telescopic rod 3 first, and then adjusts the horizontal position of the embedded assembly 1 by starting the electric push rod 5, until the deviation meets the design requirements, and through the high-precision data provided by the laser measuring instrument 22, a scientific basis is provided for the installation and adjustment of the embedded assembly 1, and subjective errors in manual measurement are avoided;

[0046] When the elevation and horizontal position of the embedded component 1 meet the design drawing requirements, the construction personnel pours concrete into the rectangular formwork, and during the pouring process, the concrete contacts the embedded component 1, and the I-shaped rod 10 on the embedded component 1 contacts the concrete, at which time the concrete exerts pressure on the I-shaped rod 10, and the I-shaped rod 10 transmits the pressure to the sensing end of the positioning device 9, so that the pressure sensor can monitor the pressure received by the embedded component 1 in real time during the pouring process. Once the monitored pressure deviation exceeds the preset threshold, the system immediately issues an alarm, and the construction personnel fine-tunes the embedded component 1 through the electric telescopic rod 3 and the electric push rod 5, to ensure that the embedded component 1 always maintains an accurate position and elevation before the concrete solidifies. After the concrete solidifies, the construction personnel loosens the bolts to release the fixation of the mounting plate 7 and the embedded component 1, then raises the height of the platform 4 through the electric telescopic rod 3 to completely separate the mounting plate 7 and the embedded component 1, then uses hoisting equipment to hoist the support frame 2 and the gantry 21 to the designated area, and finally the construction personnel takes out the positioning device 9 upward to completely separate it from the embedded component 1, completes the recycling of the positioning device 9, and through real-time monitoring of the pressure and fine-tuning of the position, the embedded component 1 can better fit the pouring form of the concrete, thereby improving the stability of the overall structure, and the I-shaped rod 10 makes the recycling process of the positioning device 9 more convenient.

The convex rod 34 moves more smoothly through the roller 37, avoiding adjustment delay caused by jamming.

[0048] The inner wall of the external frame 31 is provided with a sliding groove, the convex rod 34 contacts the inner wall of the sliding groove, the sleeve 33 contacts the inner wall of the external frame 31, and the roller 37 contacts the inner wall of the external frame 31; wherein the external frame 31 is provided with a protection device for limiting the adjustment position, so that the platform 4 can move more accurately when adjusting the height and horizontal position, reducing the adjustment deviation caused by the shaking of the platform 4.

[0049] The protection device comprises a circular tube 41 fixedly penetrating through the bottom of the outer connecting frame 31 and a sliding rod 42 slidingly installed on the inner wall of the circular tube 41, the top of the sliding rod 42 is fixedly installed with a limiting plate 43, the top of the limiting plate 43 is provided with a buffer pad 44, the bottom of the circular tube 41 is rotationally installed with a hollow tube 45, the inner wall of the hollow tube 45 is fixedly installed with a butt joint block 46, the surface of the sliding rod 42 is provided with a plurality of butt joint grooves, the butt joint block 46 is in contact with the inner wall of the butt joint groove, and the blocking effect of the limiting plate 43 can not only avoid the collision of the pre-buried assembly 1 caused by the excessive lowering of the platform 4, but also assist in hoisting work, thereby further improving the safety during hoisting.

[0050] The outer wall of the limiting plate 43 is fixedly installed with a supporting rod 47, the supporting rod 47 is in contact with the inner wall of the sliding groove, and the supporting rod 47 is adjusted by rotating the hollow tube 45, so that the construction personnel can make corresponding protection measure adjustment in time according to the actual elevation data.

[0051] When the platform 4 rises or falls, the platform 4 drives the connecting plate 32 to move synchronously, the connecting plate 32 drives the sleeve pipe 33 to move, and the sleeve pipe 33 drives the convex rod 34 to move along the sliding groove synchronously, in this process, the convex rod 34 obtains the supporting force provided by the outer connecting frame 31 through the sliding groove and transmits the supporting force to the platform 4, thereby effectively improving the stability of the platform 4, and the compression spring 35 in the deformed state applies a controllable elastic pushing force to the sleeve pipe 33, the sleeve pipe 33 transmits the elastic pushing force to the connecting plate 32, so that the connecting plate 32 and the platform 4 are always kept in close connection, and the stability of the platform 4 is improved, so that the platform 4 can more accurately perform the instruction movement when the height and horizontal position of the platform 4 are adjusted, and the adjustment deviation caused by the shaking of the platform 4 is reduced.

[0052] When the sleeve pipe 33 drives the convex rod 34 to move, the convex rod 34 drives the support 36 to move synchronously, and the support 36 drives the roller 37 to move, at this time, the roller 37 rolls along the inner wall of the outer connecting frame 31 and improves the smoothness of the movement of the convex rod 34 in the sliding groove in the rolling process, suppresses the vibration generated in the movement process, and enables the convex rod 34 to stably transmit the supporting force to the platform 4, the movement of the convex rod 34 is smoother through the roller 37, the adjustment delay caused by the jamming is avoided, and the adjustment instructions of the electric telescopic rod 3 and the electric push rod 5 can be executed more timely.

[0053] When the convex rod 34 moves downward, it first contacts the buffer pad 44, at this time, the buffer pad 44 is deformed under the action of the downward pressure, and in the deformation process, the buffer pad 44 effectively absorbs the impact force caused by the convex rod 34; then, the convex rod 34 continues to move downward, and then contacts the limiting plate 43, the limiting plate 43 applies a blocking force to it to achieve limiting, limiting the convex rod 34 from continuing to move downward, preventing the platform 4 from descending excessively; at the same time, in the process of lifting and transporting the support frame 2, the convex rod 34 keeps in close contact with the limiting plate 43, and the limiting plate 43 can provide additional support for it, which can reduce the burden borne by the electric telescopic rod 3, improve the safety during operation, and through the blocking action of the limiting plate 43, not only can the platform 4 be prevented from descending excessively to cause the pre-buried assembly 1 to collide, but also the lifting work can be assisted, further improving the safety during lifting;

[0054] According to the actual elevation position, the construction worker can adjust the height of the limiting plate 43, when adjusting, the construction worker controls the sliding rod 42 with one hand and rotates the hollow pipe 45 with the other hand, so that the butt joint block 46 is synchronously rotated, the butt joint block 46 is out of contact with the butt joint groove in the rotation, and then the limiting of the sliding rod 42 is released; then the construction worker moves the sliding rod 42 downward, the sliding rod 42 drives the limiting plate 43 and the buffer pad 44 to move downward as a whole, and at the same time, the limiting plate 43 further drives the support rod 47 to move downward along the sliding groove, which can guarantee the stability of the limiting plate 43 during movement; when the sliding rod 42 moves to the predetermined position, the construction worker rotates the hollow pipe 45, so that the butt joint block 46 contacts with the new butt joint groove, and thus the height adjustment of the limiting plate 43 is completed, and the adjustment is realized by rotating the hollow pipe 45, which is simple and convenient to operate, and the construction worker can make corresponding protection adjustment according to the actual elevation data in time.

6. A construction method for a precise installation device for embedded parts, using the precise installation device for embedded parts as described in claim 5, characterized in that, Includes the following steps: Step 1: Set up a high-precision total station with BeiDou satellite positioning system at the construction site, use the total station to conduct topographic surveys of the construction site, obtain detailed topographic data, import it into computer-aided design software, and combine it with engineering design drawings to create a three-dimensional model of the construction site. Step 2: Perform preliminary processing and assembly on the embedded component (1), and install a positioning device (9) with a positioning chip and pressure sensor on the embedded component (1). Then transport the embedded component (1) to the construction site and use a hoisting equipment with automatic positioning and adjustment functions to hoist it. The hoisting equipment hoists the embedded component (1) to the installation position and automatically adjusts the position and elevation of the embedded component (1) according to the deviation data fed back by the positioning system, so that it is initially close to the design position. Step 3: Adjust the elevation and horizontal position of the pre-embedded component (1) by using the electric telescopic rod (3) and the electric push rod (5) to perform preliminary positioning. After the preliminary positioning is completed, use a high-precision laser measuring instrument (22) to accurately measure the position and elevation of the pre-embedded component (1). Step 4: After the deviation meets the design requirements, the construction worker pours concrete. During the concrete pouring process, the positioning device (9) monitors the position and elevation changes of the embedded component (1) in real time. Once the deviation exceeds the preset threshold, the system immediately issues an alarm. The construction worker makes fine adjustments to the embedded component (1) using the electric telescopic rod (3) and the electric push rod (5) to ensure that the embedded component (1) always maintains the accurate position and elevation before the concrete solidifies.
