[0019] The present invention provides an external connection auxiliary device for the connection between a bridge and an auxiliary road, which has the following beneficial effects:

[0020] 1. The external connection auxiliary device at the connection between the bridge and the auxiliary road. The working winding motor cooperates with parts such as the slide rail, square box, winding rod, and pulling rope to enable the auxiliary box and hydraulic cylinder to move under the limit of the slide rail. The positioning plate, inner box, push spring and other parts installed inside the positioning box cooperate to control the position of the auxiliary box, so that the drive motor fixed inside the auxiliary box is aligned with the support bolts, and the drive motor rotates when pushed by the hydraulic cylinder. The working drive motor drives the support bolts to rotate through the transmission plate. The rotating support bolts penetrate the support column and enter the interior of the pillar. Multiple support bolts are installed between the support column and the pillar in sequence, which can quickly complete the installation of the support bolts between the auxiliary road and the bridge, completing the installation and fixation of the auxiliary road. Workers can complete the installation of multiple support bolts by operating the controller on the ground, ensuring the safety of workers during the installation of the bridge and auxiliary road and reducing the cost investment required for workers to work at height.

[0021] 2. The external auxiliary connection device at the connection between the bridge and the auxiliary road drives the motor to rotate the transmission plate. The transmission plate rotates inside the square slot, causing the transmission plate to rotate the support bolts. The rotating support bolts drive the fixed drill bit to rotate and drill holes in the pillars. The support bolts are partially inserted into the pillars, fixed between the pillars, and the auxiliary road can be installed. Workers no longer need to drill holes with handheld drilling equipment at high altitude and then use auxiliary equipment to install the support bolts into the holes. This reduces the amount of equipment required and the time spent working at high altitude, reducing the cost of installing the auxiliary road on one side of the bridge, ensuring the safety of workers, and reducing the safety hazards associated with operating electrical appliances at high altitude.

[0022] 3. The external connection auxiliary device at the connection between the bridge and the auxiliary road. During the movement of the auxiliary box, the positioning plate is pushed by the spring to contact the support column. When the auxiliary box drives the positioning box to move, the positioning plate is aligned with the square positioning slot. The rebounding push spring pushes the positioning plate into the square positioning slot, the winding motor is controlled to stop working, and the drive motor stays on the side of the support bolt. After the drive motor and the support bolt are positioned, multiple support bolts can be directly inserted between the two support columns and the pillar, eliminating the need for workers to operate the support bolts one by one. They only need to control the square slot to be roughly parallel to the auxiliary box when operating the support bolts, reducing the labor required for workers to work in the air and reducing labor costs.

[0023] 4. The external connection auxiliary device at the connection between the bridge and the auxiliary road removes the need for pressing the motor button, completing a single press of the motor button. Pressing the motor button once sends a signal to the signal receiver, causing it to activate and deactivate the winding motor. This quickly deactivates the winding motor, allowing it to coordinate with the positioning plate, push spring, pull wire, and electric push rod to control the position of the auxiliary box, hydraulic cylinder, drive motor, and transmission plate. This ensures rapid positioning of the drive motor and support bolts, enabling rapid installation of the support bolts. This reduces the need for support bolts to secure the bridge and auxiliary road, reduces labor costs, and mitigates operator safety hazards.

[0024] 5. The external auxiliary connection device at the bridge's connection to the auxiliary road. When the reel rod rotates to reel in the pull rope, it pulls on the sliding plate, causing the sliding plate to squeeze the support spring. At this time, the reel rod's rotation does not reel in the pull rope, but instead drives the sliding plate to move within the square box. This provides the reel rod with movement margin when the reel motor is inoperative, preventing the auxiliary box's movement from being restricted by the positioning plate, which would then cause the reel rod's rotation to apply force to the reel motor and pull rope. This protects the reel motor and pull rope, ensuring their service life and minimizing economic losses. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0042] An embodiment of the present invention provides an external connection auxiliary device at the connection of a bridge and an access road.

[0043] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16, including a bridge 1, multiple support columns 2, a service road 3, and two support pillars 4. The support columns 2 are provided with multiple threaded grooves 22 and multiple square positioning grooves 23. Support bolts 25 are arranged inside half of the threaded grooves 22. A slide rail 5 is arranged on one side of the service road 3. Two mounting bolts 6 are rotatably connected to the top of the slide rail 5, and the mounting bolts 6 are threadedly connected to the service road 3. Multiple support columns 2 are fixedly connected to the bottom of the bridge 1, and the support pillars 4 are fixedly connected to the bottom of the service road 3. The support pillars 4 are arranged on one side of the bridge 1. A position control box 8 and an auxiliary box 9 are respectively arranged at both ends of the slide rail 5. A hydraulic cylinder 10, a cable 27, and a controller 28 are arranged at one end of the auxiliary box 9. The cable 27 is fixedly connected between the controller 28 and the auxiliary box 9. A positioning button, a working button, a reset button, and a movement button are arranged on one side of the controller 28. A driving motor 11, a transmission plate 12, a positioning plate 13, a sensor 14, and a positioning box 15 are arranged inside the auxiliary box 9, reducing the number of devices to be used and the time of working at height, reducing the cost investment for installing the service road 3 on one side of the bridge 1, and ensuring the safety of the staff, reducing the potential safety hazards of operating electrical appliances at height. A positioning plug 16, an inner box 17, a pushing spring 18, a pull wire 19, a motor button 38, and an electric push rod 20 are arranged inside the positioning box 15. The working driving motor 11 drives the support bolt 25 to rotate through the transmission plate 12. The rotating support bolt 25 penetrates through the support pillar 4 and enters the inside of the support column 2 at the same time. A winding motor 29, a square box 30, and a winding rod 31 are arranged inside the position control box 8. A sliding plate 35, a support spring 36, and a signal receiver 37 are arranged inside the square box 30. The staff can complete the installation of multiple support bolts 25 by operating the controller 28 on the ground, ensuring the safety of the staff during the installation process of the bridge 1 and the service road 3, and reducing the cost investment required for the staff to work at height. A pulling rope 33 is arranged between the winding motor 29 and the auxiliary box 9.

[0044] Specifically, one end of the multiple support bolts 25 fixedly connected with drill bits 24 is rotatably inserted into the multiple threaded grooves 22. Subsequently, the slide rail 5 is installed on one side of the service road 3 through the mounting bolts 6, and the staff can move to the ground for operation. Subsequently, the winding motor 29 is controlled to work. The working winding motor 29 cooperates with parts such as the slide rail 5, the square box 30, the winding rod 31, and the pulling rope 33 to make the auxiliary box 9 and the hydraulic cylinder 10 move under the limitation of the slide rail 5.

[0045] During the movement of the auxiliary box 9, parts such as the positioning plug 16, the inner box 17, and the pushing spring 18 arranged inside the positioning box 15 cooperate to control the position of the auxiliary box 9, so that the driving motor 11 fixedly connected inside the auxiliary box 9 is aligned with the support bolt 25.

[0046] Under the action of the inductor 14 and the positioning plate 13, the transmission plate 12 fixedly installed by the driving motor 11 is aligned with the square groove 26 opened in the support bolt 25. Subsequently, the driving motor 11 is controlled to work. The working hydraulic cylinder 10 pushes the transmission plate 12 fixed by the driving motor 11 into the square groove 26. Then, the driving motor 11 rotates when it is pushed by the hydraulic cylinder 10. The working driving motor 11 drives the support bolt 25 to rotate through the transmission plate 12. The rotating support bolt 25 penetrates the support column 4 and enters the column 2 at the same time. A plurality of support bolts 25 are sequentially installed between the support column 4 and the column 2, and the installation of the support bolts 25 between the auxiliary road 3 and the bridge 1 can be quickly completed, and the installation and fixation of the auxiliary road 3 can be completed. The staff can complete the installation of a plurality of support bolts 25 by operating the controller 28 on the ground, ensuring the safety of the staff during the installation of the bridge 1 and the auxiliary road 3, and reducing the cost input required for the staff to work at high altitudes.

[0047] Please refer to again Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The transmission plate 12 is fixedly connected to the driving motor 11, the driving motor 11 is fixedly connected to the hydraulic cylinder 10, the hydraulic cylinder 10 is fixedly connected to one end of the auxiliary box 9, an empty groove is opened on one side of the auxiliary box 9 close to the position control box 8, the hydraulic cylinder 10 pushes the driving motor 11 to move inside the auxiliary box 9, and the transmission plate 12 fixed by the driving motor 11 is pushed into the square groove 26 opened in the support bolt 25. One end of the support bolt 25 is fixedly connected with a drill bit 24, the other end of the support bolt 25 is provided with a square groove 26, the inductor 14 is fixedly connected to the bottom of one side of the driving motor 11, reducing the number of devices to be used and the time of working at high altitudes, reducing the cost input for installing the auxiliary road 3 on one side of the bridge 1, and ensuring the safety of the staff, reducing the potential safety hazards of operating electrical appliances at high altitudes. The positioning plate 13 is fixedly connected to the bottom of the transmission plate 12, and the positioning plate 13 is arranged on one side of the square groove 26.

[0048] Specifically, press the positioning button set on the controller 28 to make the inductor 14 work to detect the distance between the driving motor 11 and the support bolt 25. Then, the driving motor 11 works. When the positioning plate 13 rotates to one side of the inductor 14, the inductor 14 controls the hydraulic cylinder 10 to work and the driving motor 11 stops working, so that the hydraulic cylinder 10 pushes the driving motor 11 to move inside the auxiliary box 9, and the transmission plate 12 fixed by the driving motor 11 is pushed into the square groove 26 opened in the support bolt 25.

[0049] Subsequently, the staff presses the working button set by the controller 28 to control the synchronous operation of the driving motor 11 and the hydraulic cylinder 10. The working hydraulic cylinder 10 pushes the driving motor 11 to move, and the driving motor 11 operates to drive the transmission plate 12 to rotate. The transmission plate 12 inside the square groove 26 rotates, causing the transmission plate 12 to drive the support bolt 25 to rotate. The rotating support bolt 25 drives the fixed drill bit 24 to rotate and drill holes in the support column 2. Insert a part of the support bolt 25 into the support column 2 to fix the support bolt 25 between the support column 2 and the support column 4, and then the auxiliary road 3 can be installed. The staff does not need to hold the drilling equipment at high altitude to drill holes and then use auxiliary equipment to install the support bolt 25 into the hole, reducing the number of equipment required and the time of working at high altitude, reducing the cost investment for installing the auxiliary road 3 on one side of the bridge 1, and ensuring the safety of the staff and reducing the potential safety hazards of operating electrical appliances at high altitude.

[0050] Please refer to again Figure 3 、 Figure 4 、 Figure 7 、 Figure 9 、 Figure 10 and Figure 11 ., the inner box 17 is fixedly connected inside the positioning box 15. One end of the positioning plug 16 extends out of the positioning box 15. There are two pushing springs 18, and both pushing springs 18 are fixedly connected between the inner box 17 and the positioning plug 16. One end of the pull wire 19 extends into the inner box 17, and the pull wire 19 is fixedly connected between the positioning plug 16 and the electric push rod 20. The electric push rod 20 pulls the positioning plug 16 through the pull wire 19, causing the positioning plug 16 to leave the square positioning groove 23 opened on the support column 4. A holding groove plate 21 is fixedly sleeved outside the electric push rod 20, and the holding groove plate 21 is fixedly connected inside the inner box 17. The inner box 17 is fixedly connected to one side inside the auxiliary box 9. The positioning plug 16 is arranged on one side of one of the square positioning grooves 23. After the positioning plug 16 is aligned with the square positioning groove 23, the rebounding pushing spring 18 pushes the positioning plug 16 into the square positioning groove 23. The winding motor 29 is controlled to stop working, and the driving motor 11 stays on one side of the support bolt 25. One end of the auxiliary box 9 extends to the bottom of the auxiliary road 3.

[0051] Specifically, after pressing the moving button, the electric push rod 20 and the winding motor 29 work successively. The electric push rod 20 installed inside the inner box 17 where the slot plate 21 is held down works. The working electric push rod 20 pulls the positioning plug 16 through the wire 19, causing the positioning plug 16 to leave the inside of the square positioning slot 23 opened in the support column 4. Subsequently, the electric push rod 20 stops working and resets. At this time, the winding motor 29 works to pull the auxiliary box 9 to move. During the movement of the auxiliary box 9, the positioning plug 16 is pushed by the pushing spring 18 to bounce and contact the support column 4. When the auxiliary box 9 drives the positioning box 15 to move and aligns the positioning plug 16 with the square positioning slot 23, the rebounding pushing spring 18 pushes the positioning plug 16 into the inside of the square positioning slot 23, and the winding motor 29 is controlled to stop working. The drive motor 11 stays on one side of the support bolt 25. After the positioning of the drive motor 11 and the support bolt 25 is completed, multiple support bolts 25 can be directly inserted between the two support columns 4 and the support 2, avoiding the need for staff to operate each support bolt 25 one by one. When operating the support bolt 25, it is only necessary to control the square groove 26 to be roughly parallel to the auxiliary box 9, reducing the labor force required for the staff to work in the air and reducing the investment in labor costs.

[0052] After one support bolt 25 is installed, repeating the above work can relatively automatically complete the installation of multiple support bolts 25, ensuring the rapid and stable installation of the access road 3 on one side of the bridge 1.

[0053] Please refer to again Figure 1 、 Figure 4 、 Figure 12 、 Figure 13 、 Figure 14 、 Figure 15 and Figure 16, a slider 7 is fixedly connected to the top of the auxiliary box 9. The pulling rope 33 is fixedly connected between the slider 7 and the winding rod 31. When the winding rod 31 rotates, it does not wind the pulling rope 33 but drives the sliding plate 35 to move inside the square box 30. To provide a moving margin for the winding rod 31 during the period when the winding motor 29 stops working, and to avoid the force exerted on the winding motor 29 and the pulling rope 33 by the rotation of the winding rod 31 after the movement of the auxiliary box 9 is restricted by the positioning plug 16, thus protecting the winding motor 29 and the pulling rope 33. One end of the pulling rope 33 extends into the position control box 8. Two collar rings 32 are fixedly sleeved on the outer side of the winding rod 31. The collar rings 32 are sleeved on the outer side of the winding rod 31 to prevent the pulling rope 33 from affecting the movement of the sliding plate 35. The winding motor 29 is fixedly connected between the square box 30 and the position control box 8. The position control box 8 is fixedly connected to the slide rail 5. A guiding notch 34 is formed on one side of the square box 30. One end of the winding rod 31 passes through the guiding notch 34 and is fixedly connected to the sliding plate 35. The sliding plate 35 is arranged inside the square box 30. The supporting spring 36 is fixedly connected between the sliding plate 35 and the position control box 8. After the supporting spring 36 is fully contracted, the supporting spring 36 is equivalent to a tube that plays a supporting role, preventing the sliding plate 35 from damaging the signal receiver 37. The signal receiver 37 is fixedly connected inside the position control box 8.

[0054] Specifically, a slider 7 is slidably connected to one side of the slide rail 5, enabling the auxiliary box 9 fixedly installed with the slider 7 to reciprocate at the bottom of the slide rail 5. The square box 30 at one end of the working winding motor 29 rotates, and the rotating square box 30 drives the winding rod 31 to rotate.

[0055] And a pulling rope 33 is fixedly connected between the winding rod 31 and the slider 7. The rotating winding rod 31 winds the pulling rope 33, causing the pulling rope 33 to pull the slider 7 to move on one side of the slide rail 5, so that the auxiliary box 9 fixed to the bottom of the slider 7 drives parts such as the driving motor 11, the transmission plate 12, the positioning plate 13, the inductor 14, the positioning box 15, the positioning plug 16, the inner box 17, and the motor button 38 inside to move, causing the driving motor 11 to move towards the support bolt 25 for the installation of multiple support bolts 25.

[0056] After one support bolt 25 is installed, the working electric push rod 20 pulls the positioning plate 16 to press the motor button 38. When the auxiliary box 9 moves, the rebounding push spring 18 applies force to the positioning plate 16. After the positioning plate 16 is aligned with the square positioning groove 23, the rebounding push spring 18 pushes the positioning plate 16 to move, causing the motor button 38 to lose its pressure, completing a single press of the motor button 38. After the motor button 38 is pressed once, it sends a signal to the signal receiver 37, causing the signal receiver 37 to control the winding motor 29 to start, causing the signal receiver 37 to control the winding motor 29 to stop. The winding motor 29 can be quickly controlled to stop working, so that the winding motor 29 cooperates with the positioning plug plate 16, the push spring 18, the pull wire 19, the electric push rod 20 and other parts, and the positions of the auxiliary box 9, the hydraulic cylinder 10, the drive motor 11, the transmission plate 12 and other parts are controlled to ensure that the positions of the drive motor 11 and the support bolts 25 are quickly positioned, and the support bolts 25 are quickly installed, thereby reducing the speed of the support bolts 25 fixing the bridge 1 and the auxiliary road 3, reducing labor cost investment, and reducing the danger of staff operation.

[0057] A sliding plate 35 is provided inside the square box 30, and the reeling rod 31 is fixedly connected to the sliding plate 35 after passing through the guide slot 34. A support spring 36 is fixedly connected between the sliding plate 35 and the square box 30. Therefore, when the reeling rod 31 is reeling, when the positioning plate 16 is inserted into the square positioning slot 23 and the reeling motor 29 stops working, the reeling rod 31 rotates to reel the pull rope 33, causing the reeling rod 31 to pull the sliding plate 35, causing the slide plate 35 to squeeze the support spring 36. At this time, the rotation of the reeling rod 31 does not reel the pull rope 33, but instead drives the sliding plate 35 to move inside the square box 30. This provides a margin for the reeling rod 31 to move when the reeling motor 29 stops working, prevents the reeling rod 31 from applying force to the reeling motor 29 and the pull rope 33 after the auxiliary box 9 moves and is restricted by the positioning plate 16, and protects the reeling motor 29 and the pull rope 33, thereby ensuring the service life of the reeling motor 29 and the pull rope 33 and reducing economic losses.

[0058] When the support spring 36 is fully contracted, the support spring 36 is equivalent to a tube that plays a supporting role, preventing the sliding plate 35 from causing damage to the signal receiver 37. The ring 32 is sleeved on the outside of the winding rod 31 to prevent the pulling rope 33 from affecting the movement of the sliding plate 35.
