[0002] Embedded parts are components pre-installed in concealed works and are also components placed during the structural pouring, used for the lapping when building the upper structure to facilitate the installation and fixation of external engineering equipment bases. For example, in the patent with the application number: CN202021314599.3, a stable steel structure embedded part installation equipment is disclosed, including a fixed frame. Rectangular grooves are symmetrically opened at both ends of the fixed frame. Threaded rods are rotatably connected inside the two rectangular grooves. Movable blocks are threadedly connected to the outer ends of the threaded rods corresponding to the positions inside the rectangular grooves. Symmetrically fixed connections are provided at one end of the fixed frame corresponding to the threaded rods with runners, and belts are sleeved on the outer ends of the two runners. The structure of the present utility model is scientific and reasonable, safe and convenient to use. It is provided with rectangular grooves, threaded rods, movable blocks, runners, belts, turntables, fixing plates, connecting plates, chutes and mounting seats. By rotating the turntable, the turntable drives the threaded rod to rotate uniformly. At the same time, through the cooperation of the runner and the belt, the threaded rods at both ends drive the movable blocks to move uniformly along the rectangular grooves, thereby driving the mounting seat to move and performing lateral positioning on the mounting seat, improving the positioning accuracy of the steel structure embedded parts.

After the embedded part is supported on the top of the supporting plate 204, the supporting component 1 is placed at the general position where the embedded part is to be installed, and then the installation height of the embedded part can be adjusted. The top surface height of the embedded part supported by the supporting plate 204 can be observed through a level, so as to calibrate and control the height of the embedded part. The use height of the installation frame 101 can be adjusted through the telescopic column 102, so as to adjust the installation height of the embedded part supported by the supporting plate 204. The adjustment is convenient and flexible. After the height adjustment is completed, the installation position of the embedded part can be adjusted.

[0028] In the embodiment of the present disclosure, the longitudinal screw rod 103 and the transmission rod 104 are arranged parallel to each other, and the included angle between the longitudinal screw rod 103 and the transverse screw rod 202 is 90 degrees. A positioning pin rod 1011 is installed inside the installation frame 101, and a positioning top spring 1012 is provided at the top of the positioning pin rod 1011. The two ends of the positioning top spring 1012 respectively abut against the top of the positioning pin rod 1011 and the inside of the installation frame 101. A first positioning groove 1051 and a second positioning groove 1052 are provided on the outer surface of the shaft body of the switching shaft 105. A longitudinal driving gear 1031 is provided at one end of the longitudinal screw rod 103, and a transverse driving gear 1041 is provided at one end of the transmission rod 104. A switching gear 1053 is provided on the side surface of the switching shaft 105. During use, the switching shaft 105 has the function of adjusting the horizontal and vertical installation positions of the embedded part, so that the worker does not need to move when adjusting the installation position of the embedded part, and the operation is convenient and the adjustment is flexible. Under the action of the positioning top spring 1012, when the switching shaft 105 is pressed or pulled out, the positioning pin rod 1011 can be inserted into the positioning grooves at different positions, so as to realize the adjustment of the embedded part in different directions, and the positioning pin rod 1011 can position the use position of the switching shaft 105 by being inserted into the positioning grooves at the corresponding positions, avoiding the phenomenon that its use position accidentally changes during rotation adjustment, and the use is stable. After the height adjustment is completed, through equipment such as total stations and theodolites, the calibration and adjustment of the installation position of the embedded part can be realized.

[0029] In an embodiment of the present disclosure, when the positioning pin rod 1011 is inserted into the first positioning groove 1051, the switching gear 1053 meshes with the teeth of the longitudinal driving gear 1031 for transmission. And when the positioning pin rod 1011 is inserted into the second positioning groove 1052, the switching gear 1053 meshes with the teeth of the transverse driving gear 1041 for transmission. During use, when the positioning pin rod 1011 is inserted into the first positioning groove 1051, the switching gear 1053 meshes with the teeth of the longitudinal driving gear 1031 for transmission. At this time, the switching gear 1053 and the transverse driving gear 1041 are separated from each other. Thus, when the switching shaft 105 rotates, the longitudinal installation position of the embedded part can be adjusted. When the switching shaft 105 rotates, the switching gear 1053 can drive the longitudinal screw rod 103 to rotate through the longitudinal driving gear 1031. When the longitudinal screw rod 103 rotates, it can drive the longitudinal positioning seat 201 to move longitudinally inside the installation frame 101 through the screw thread on the rod body, thereby changing the longitudinal installation position of the embedded part. When the positioning pin rod 1011 is inserted into the second positioning groove 1052, the switching gear 1053 meshes with the teeth of the transverse driving gear 1041 for transmission. And at this time, the switching gear 1053 and the longitudinal driving gear 1031 are separated from each other. Thus, when the switching shaft 105 rotates, the transverse installation position of the embedded part can be adjusted. When the switching shaft 105 rotates, the switching gear 1053 can drive the transmission rod 104 to rotate through the transverse driving gear 1041. The cross-sectional shape of the rod body in the middle of the transmission rod 104 is a regular polygon, and a driving groove 2051 is provided inside the linkage gear 205. The rod body part with a regular polygon cross-section of the transmission rod 104 is inserted into the driving groove 2051. When the transmission rod 104 rotates, it can drive the linkage gear 205 to rotate through the driving groove 2051. One end of the transverse screw rod 202 is provided with a transmission gear 2021, and the teeth of the transmission gear 2021 and the linkage gear 205 mesh for transmission. When the linkage gear 205 rotates, it can drive the transverse screw rod 202 to rotate through the transmission gear 2021. When the transverse screw rod 202 rotates, it can drive the transverse positioning seat 203 to move transversely on the side of the longitudinal positioning seat 201 through the screw thread on the rod body, thereby changing the transverse installation position of the embedded part. The adjustment is convenient and the use is flexible.

[0030] In an embodiment of the present disclosure, the axial distance between the longitudinal driving gear 1031 and the transverse driving gear 1041 is greater than the gear thickness of the switching gear 1053. This design ensures that the switching gear 1053 will not simultaneously mesh with the teeth of the longitudinal driving gear 1031 and the transverse driving gear 1041, guaranteeing the independence of the adjustment of the horizontal and vertical installation positions of the embedded part, and the adjustment is precise and delicate.

[0031] Specific usage method and function of this embodiment: In the present invention, the supporting component 1 can adjust the installation height of the embedded part. After the embedded part is supported on the top of the supporting plate 204, the supporting component 1 is placed at the general position where the embedded part is to be installed, and then the installation height of the embedded part can be adjusted. The top surface height of the embedded part supported by the supporting plate 204 can be observed through a level, so as to calibrate and control the height of the embedded part. The use height of the installation frame 101 can be adjusted through the telescopic column 102, thereby also adjusting the installation height of the embedded part supported by the supporting plate 204. The adjustment is convenient and flexible. After the height adjustment is completed, the installation position of the embedded part can be adjusted. The switching shaft 105 has the function of adjusting the horizontal and vertical installation positions of the embedded part, so that the worker does not need to move when adjusting the installation position of the embedded part, the operation is convenient, and the adjustment is flexible. Under the action of the positioning top spring 1012, when the switching shaft 105 is pressed or pulled out, the positioning pin rod 1011 can be inserted into the positioning grooves at different positions, so as to realize the adjustment of the embedded part in different directions. Moreover, the positioning pin rod 1011 can position the use position of the switching shaft 105 by being inserted into the corresponding positioning groove, avoiding the phenomenon that its use position accidentally changes during the rotation adjustment, and the use is stable. After the height adjustment is completed, through equipment such as total station and theodolite, the calibration and control of the installation position of the embedded part can be realized. When the positioning pin rod 1011 is inserted into the first positioning groove 1051, the gear teeth of the switching gear 1053 and the longitudinal driving gear 1031 are engaged in transmission. At this time, the switching gear 1053 and the horizontal driving gear 1041 are separated from each other. Therefore, when the switching shaft 105 rotates at this time, the longitudinal installation position of the embedded part can be adjusted. When the switching shaft 105 rotates, the switching gear 1053 can drive the longitudinal screw rod 103 to rotate through the longitudinal driving gear 1031. When the longitudinal screw rod 103 rotates, it can drive the longitudinal positioning seat 201 to move longitudinally inside the installation frame 101 through the rod body thread, thereby changing the longitudinal installation position of the embedded part. When the positioning pin rod 1011 is inserted into the second positioning groove 1052, the gear teeth of the switching gear 1053 and the horizontal driving gear 1041 are engaged in transmission, and at this time, the switching gear 1053 and the longitudinal driving gear 1031 are separated from each other. Therefore, when the switching shaft 105 rotates at this time, the horizontal installation position of the embedded part can be adjusted. When the switching shaft 105 rotates, the switching gear 1053 can drive the transmission rod 104 to rotate through the horizontal driving gear 1041. When the transmission rod 104 rotates, it can drive the linkage gear 205 to rotate through the driving groove 2051. When the linkage gear 205 rotates, it can drive the horizontal screw rod 202 to rotate through the transmission gear 2021. When the horizontal screw rod 202 rotates, it can drive the horizontal positioning seat 203 to move horizontally on the side of the longitudinal positioning seat 201 through the rod body thread, thereby changing the horizontal installation position of the embedded part.
