Detailed implementation manners
[0030] To make the purposes, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0031] Referring to Figures 1-4 , the present utility model provides a technical solution: a device for adjusting the positioning of pre-embedded bolts of a tower crane foundation, including a positioning seat 1 and a positioning and distance-expanding mechanism. Positioning plates 2 are installed at the bottoms on both sides of the positioning seat 1, and a positioning cover 3 is installed on the outer side of the top of the positioning plate 2. The positioning cover 3 can be used in cooperation with the positioning plate 2 to provide a force application medium for the user to position the size of the pre-embedded bolt according to the actual external needs, avoiding the situation that it is difficult to position pre-embedded bolts of different sizes when the positioning plate 2 and the positioning cover 3 are used. Therefore, the positioning adaptability and flexibility of the positioning cover 3 are improved.
[0032] Referring to Figures 1-4, in a preferred embodiment, the positioning and distance-expanding mechanism includes a main connecting rod 4, which is movably connected to the left side inside the positioning cover 3. A secondary connecting rod 5 located on the right side of the positioning cover 3 is movably connected inside the main connecting rod 4. Fixed shells 6 are respectively fixedly connected to the outer sides of the main connecting rod 4 and the secondary connecting rod 5. Fixed seats 7 are movably connected to both sides inside the fixed shells 6. A sliding groove 8 is opened at the top of the positioning plate 2. Sliding seats 9 movably connected inside the sliding groove 8 are fixedly connected to both sides of the bottom of the positioning cover 3. The distance-expanding force-applying mechanism is arranged on the outer side of the fixed shell 6. Place the positioning seat 1 horizontally on the top of the steel bar frame tied at the installation position of the external tower crane. Then, hold the embedded bolt and align it with the outer side of the fixed seat 7. Since the outer side of the fixed seat 7 is inclined, when the held embedded bolt is translated and contacts the fixed seat 7, the fixed seat 7 moves to both sides under the influence of the translation force of the embedded bolt, moving the embedded bolt into the fixed seat 7, so that the fixed seat 7 cooperates with the fixed shell 6 to clamp and position the embedded bolt. Subsequently, according to the actual required position of the embedded bolt embedding, hold the main connecting rod 4 and the secondary connecting rod 5 respectively, and drive the embedded bolt to move for left-right translation adjustment operations through the cooperation of the fixed shell 6 and the fixed seat 7. Then, hold the positioning cover 3 and drive the main connecting rod 4 and the secondary connecting rod 5 to move back and forth to adjust the front and rear positions of the embedded bolt. At this time, the sliding seat 9 moves inside the sliding groove 8 following the positioning cover 3 to perform a sliding connection operation between the positioning cover 3 and the positioning plate 2, so that the position of the embedded bolt meets the installation and embedding requirements of the external tower crane. Then, the positioning seat 1 can be fixed to the steel bar frame by welding. The distance-expanding force-applying mechanism includes a force-applying groove 10, a spring 11 and a force-applying plate 12. The force-applying groove 10 is opened on the outer side of the fixed seat 7. The spring 11 is arranged inside the force-applying groove 10. One end of the spring 11 is fixedly connected to the inner wall of the fixed shell 6, and the other end of the spring 11 is fixedly connected to the inner wall of the force-applying groove 10. The force-applying plate 12 is movably connected to the top inside the fixed shell 6. When the fixed shell 6 cooperates with the fixed seat 7, the fixed shell 6 can apply a distance-expanding and clamping positioning force to the fixed seat 7, enabling the fixed seat 7 to perform a clamping and positioning operation on the external embedded bolt, avoiding the situation that it is difficult to position the external embedded bolt when the fixed seat 7 is used. Therefore, the positioning effect of the fixed seat 7 on the embedded bolt is improved.
[0033] Refer to Figure 3, in a preferred embodiment, a force - applying bolt 13 is threadedly connected to the top of the fixed housing 6. A rotation groove 14 is formed in the top of the force - applying plate 12, and a rotating frame 15 is rotatably connected inside the rotation groove 14. The top of the rotating frame 15 is fixedly connected to the bottom of the force - applying bolt 13. When the force - applying plate 12 is used in cooperation with the fixed seat 7, it can provide a medium for the user to apply a downward force on the force - applying plate 12, so that the bottom of the force - applying plate 12 is in force - applying contact with the top of the fixed seat 7, avoiding the situation that it is difficult to apply a tightening and stabilizing force to the stabilizing seat when the force - applying plate 12 is used. Therefore, the usability and the force - applying stability effect of the force - applying plate 12 are improved. A connection port 16 is formed on the outer side of the fixed housing 6, and the fixed seat 7 passes through the fixed housing 6 through the connection port 16. Connection grooves 17 in contact with the connection port 16 are formed at both the top and the bottom of the fixed seat 7. When the fixed housing 6 is used in cooperation with the fixed seat 7, it can provide a moving space for the fixed seat 7 to pass through the fixed housing 6 and perform the work of limiting the movable connection between the fixed seat 7 and the fixed housing 6, avoiding the situation that the fixed seat 7 is difficult to move or is displaced during operation. Therefore, the usability and stability of the fixed seat 7 are improved.
[0034] Refer to Figure 2 , in a preferred embodiment, a screw hole 18 is formed in the top of the positioning cover 3, a screw rod 19 is threadedly connected inside the screw hole 18, and a stabilizing disk 20 in contact with the inner wall of the sliding groove 8 is fixedly connected to the bottom of the screw rod 19. When the positioning plate 2 is used in cooperation with the positioning cover 3, it can provide a medium for the user to position between the positioning cover 3 and the positioning plate 2, avoiding the situation that it is difficult to position the positioning cover 3 during use. Therefore, the positioning convenience of the positioning cover 3 is improved. The top inside the positioning cover 3 is movably connected with a pressing plate 21, an activity hole 22 is formed in the top of the pressing plate 21, and the screw rod 19 passes through the pressing plate 21 through the activity hole 22. When the screw rod 19 is used in cooperation with the positioning cover 3, the tightening and positioning work between the positioning cover 3, the main connecting frame 4 and the sub - connecting frame 5 can be carried out by means of the threaded lifting force of the screw rod 19, avoiding the situation that it is difficult to position the main connecting frame 4 and the sub - connecting frame 5 when the positioning cover 3 is used. Therefore, the positioning convenience of the main connecting frame 4 and the sub - connecting frame 5 is improved.
[0035] Refer to Figures 2-4, in a preferred embodiment, a tightening groove 23 is formed in the inner wall of the movable hole 22, and a tightening ring 24 is rotatably connected inside the tightening groove 23. The inner side of the tightening ring 24 is fixedly connected to the surface of the screw 19. When the screw 19 is used in cooperation with the tightening plate 21, the rotation connection force application work can be carried out between the screw 19 and the tightening plate 21, avoiding the situation that it is difficult to apply the tightening force to the tightening plate 21 when the screw 19 is used. Therefore, the connection force application effect between the tightening plate 21 and the screw 19 is improved. A synchronous ring 25 is fixedly connected to the inner side of the bottom of the fixed shell 6, and a synchronous frame 26 is movably connected inside the synchronous ring 25. When the fixed shell 6 is used in cooperation with the fixed seat 7, the movement synchronization work can be carried out between the fixed shells 6 located on both sides of the positioning seat 1, avoiding the situation that it is difficult to perform the movement synchronization when the fixed shell 6 is used, resulting in the need for separate adjustment of each fixed shell 6. Therefore, the movement synchronization of the fixed shell 6 is improved.
[0036] Specifically, the working process or principle of the device for adjusting the positioning of the embedded bolts of the tower crane foundation is as follows: When in use, first place the positioning seat 1 horizontally on the top of the steel bar frame tied at the external tower crane installation position, and then hold the embedded bolt and align it with the outer side of the fixed seat 7. Since the outer side of the fixed seat 7 is inclined, when the embedded bolt is held and translated and contacts the fixed seat 7, the fixed seat 7 moves to both sides under the influence of the translation force of the embedded bolt, and the embedded bolt is moved into the fixed seat 7. Note that the surface of the embedded bolt needs to contact the surface of the fixed shell 6 to ensure that the clamping and positioning positions of the fixed seat 7 for the embedded bolt are consistent. At this time, the spring 11 and the force application groove 10 apply a thrust to the fixed seat 7, so that the fixed seat 7 and the fixed shell 6 cooperate to perform the clamping and positioning work on the embedded bolt. At the same time, the connecting groove 17 moves inside the connecting port 16 following the fixed seat 7 to perform the movable connection and limiting work between the fixed seat 7 and the fixed shell 6. Then, rotate the force application bolt 13 to apply a downward thrust to the force application plate 12 through the rotating frame 15, so that the bottom of the force application plate 12 contacts and presses tightly against the top of the fixed seat 7 to perform the pressing and stabilizing work between the fixed seat 7 and the fixed shell 6, ensuring the positioning stability of the fixed seat 7 for the embedded bolt. Subsequently, according to the actual required position of the embedded bolt embedding, hold the main connecting frame 4 and the auxiliary connecting frame 5 respectively, and drive the embedded bolt to move left and right through the cooperation of the fixed shell 6 and the fixed seat 7 to perform the left and right translation adjustment operation. At this time, the synchronous ring 25 and the synchronous frame 26 cooperate to perform the translation connection synchronization work on the fixed boxes fixed on the surfaces of the main connecting frame and the auxiliary connecting frame 5. Then, hold the positioning cover 3 and drive the main connecting frame 4 and the auxiliary connecting frame 5 to move back and forth to adjust the front and back positions of the embedded bolt. At this time, the sliding seat 9 moves inside the sliding groove 8 following the positioning cover 3 to perform the sliding connection work between the positioning cover 3 and the positioning plate 2, so that the position of the embedded bolt meets the installation and embedding requirements of the external tower crane. Then, rotate the screw rod 19 to apply a downward moving force to the stabilizing disc 20 through the cooperation of the screw rod 19, so that the bottom of the stabilizing disc 20 contacts and presses tightly against the inner wall of the sliding groove 8 to perform the pressing and positioning work between the positioning cover 3 and the positioning plate 2. At the same time, the tightening ring 24 rotates inside the tightening groove 23 following the screw rod 19 to perform the rotating connection work between the screw rod 19 and the tightening plate 21, and drives the tightening plate 21 to move downward following the screw rod 19 to contact and press tightly against the tops of the main connecting frame 4 and the auxiliary connecting frame 5 to perform the positioning work between the main connecting frame 4, the auxiliary connecting frame 5 and the positioning cover 3, ensuring the position of the embedded bolt after adjustment. After the position of the embedded bolt is adjusted, the positioning seat 1 can be fixed to the steel bar frame by welding to prepare for the subsequent concrete pouring.
