Description

Technical Field

[0001] This utility model relates to the field of tunnel lining technology, specifically to a driving device for a ring-shaped steel bar. Background Technology

[0002] Tunnel lining is an important step in tunnel construction, and different types of tunnels use different lining structures. Tunnels are classified according to their cross-sectional shape into circular tunnels, rectangular tunnels, and horseshoe-shaped tunnels.

[0003] The existing lining method for circular tunnels involves placing multiple ring reinforcement bars inside the tunnel and connecting and reinforcing them with longitudinal reinforcement bars. Concrete is then poured onto the steel cage formed by the ring and longitudinal reinforcement bars to complete the lining. A cage-type steel reinforcement lining method is proposed: This method uses a ring reinforcement forming machine or a fully automatic steel bar bending and forming machine to generate spiral-shaped ring reinforcement bars. These ring reinforcement bars are placed inside the full-section tunnel. After the ring reinforcement bars are formed, longitudinal reinforcement bars are then placed on top of them. The spiral-shaped ring reinforcement bars and longitudinal reinforcement bars combine to form a cage-type steel cage. Finally, concrete is poured onto the ring and longitudinal reinforcement bars to complete the lining of the circular tunnel.

[0004] In the process of generating ring-shaped steel bars, the ring-shaped steel bar forming machine (or fully automatic steel bar bending and forming machine) uses its own thrust to push the ring-shaped steel bar to rotate, thereby making the ring-shaped steel bar move forward continuously. However, the thrust of the ring-shaped steel bar forming machine is limited. As the length and weight of the ring-shaped steel bar increase during continuous generation, the ring-shaped steel bar forming machine has difficulty pushing it, which limits the length of the generated ring-shaped steel bar. Utility Model Content

[0005] The purpose of this invention is to provide a driving device for a ring-shaped steel bar to solve the problems in the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A driving device for a ring-shaped reinforcing bar includes two or more main frames connected by a connecting structure. A fixing component is installed on the connecting structure to keep all main frames in a fixed state. Each main frame is equipped with a rotatable first cylindrical gear and a second cylindrical gear. The first cylindrical gear has a circumferentially arranged annular groove in the middle of its sidewall, and the second cylindrical gear has another circumferentially arranged annular groove in the middle of its sidewall. The ring-shaped reinforcing bar passes between the two annular grooves and is clamped by them. The top of the sidewall of the first cylindrical gear meshes with the top of the sidewall of the second cylindrical gear, and the bottom of the sidewall of the first cylindrical gear meshes with the bottom of the sidewall of the second cylindrical gear. The device also includes a driving component that drives the first cylindrical gear to rotate, and the second cylindrical gear follows the rotation of the first cylindrical gear, causing the ring-shaped reinforcing bar to rotate.

[0007] Furthermore, the drive assembly includes a first drive motor mounted on the main frame, the output shaft of the first drive motor being fixedly connected to a through shaft, and one or more vertical bearings being provided on the through shaft, all of which are fixedly connected to the main frame; a first bevel gear is fixedly provided on the through shaft, and a second bevel gear is coaxially connected to the first cylindrical gear, with the first bevel gear meshing with the second bevel gear.

[0008] Furthermore, the specific structure of the rotatable first and second cylindrical gears on the main frame is as follows: a first mounting bracket and a second mounting bracket are installed on the main frame. The first cylindrical gear is rotatably mounted on the first mounting bracket. A spring holder is fixedly installed on the second mounting bracket. The spring holder has a horizontal through hole. A horizontally sliding slide rod is connected in the through hole. One end of the slide rod is connected to a sliding seat. A spring is sleeved on the slide rod. One end of the spring is connected to the spring holder, and the other end of the spring is connected to the sliding seat. A bearing is installed on the sliding seat, and the second cylindrical gear is connected to the bearing.

[0009] Furthermore, the through shaft is provided with a plurality of first bevel gears, and a plurality of second bevel gears are respectively connected thereto; a first bevel gear, a second bevel gear, a first mounting bracket, a second mounting bracket, a first cylindrical gear and a second cylindrical gear form a drive unit, and a frame is provided with a plurality of drive units.

[0010] Furthermore, the connecting structure is a connecting rod, which is connected to multiple main frames via multiple first telescopic hydraulic cylinders, and one end of the connecting rod is connected to the vehicle body; the fixing component is a stabilizing bracket, which is connected to the other end of the connecting rod, and the stabilizing bracket is equipped with one or more second telescopic hydraulic cylinders, with the piston rod of the second telescopic hydraulic cylinder facing downwards to support the connecting rod.

[0011] Furthermore, it also includes a pair of parallel idler rollers and an I-beam. The idler rollers are placed at the bottom of the ring-shaped steel bar, and one end of the idler rollers is connected to a second drive motor. The idler rollers are used to drive the ring-shaped steel bar forward. Multiple brackets are installed on the top of the I-beams, and two or more rollers are installed on the brackets. The idler rollers are placed on the multiple brackets, and the idler rollers abut against the rollers of the brackets.

[0012] Compared with the prior art, this utility model has the following advantages and beneficial effects: Two or more main frames are connected by a connecting structure to form a whole, so that the main frames are fixed in a fixed state through the fixing components. During the driving of the ring-shaped steel bar, the stability of multiple main frames can be maintained. The driving component drives the first cylindrical gear to rotate, and the second cylindrical gear follows the rotation of the first cylindrical gear. The annular grooves of the first and second cylindrical gears clamp the ring-shaped steel bar. The rotation of the first and second cylindrical gears causes the ring-shaped steel bar to spiral forward, thereby providing power for the rotation of the ring-shaped steel bar, reducing the load on the ring-shaped steel bar forming machine. This allows the ring-shaped steel bar forming machine to continuously push the ring-shaped steel bar even when it is heavy, so that when it produces a long ring-shaped steel bar, it can complete the continuous pushing of the ring-shaped steel bar.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model, so as to provide a better understanding of the concept of the present utility model, the technical problem solved, the technical features constituting the technical solution and the technical effects brought about.

[0021] like Figures 1-5As shown, a driving device for a ring-shaped reinforcing bar includes two or more main frames 1, which are connected by a connecting structure. A fixing component is installed on the connecting structure to keep all the main frames 1 in a fixed state. Each main frame 1 is equipped with a rotatable first cylindrical gear 2 and a second cylindrical gear 3. The first cylindrical gear 2 has a circumferentially arranged annular groove 4 in the middle of its sidewall, and the second cylindrical gear 3 has another circumferentially arranged annular groove 4 in the middle of its sidewall. The ring-shaped reinforcing bar 21 passes between the two annular grooves 4 and is clamped by them. The top of the sidewall of the first cylindrical gear 2 meshes with the top of the sidewall of the second cylindrical gear 3, and the bottom of the sidewall of the first cylindrical gear 2 meshes with the bottom of the sidewall of the second cylindrical gear 3. The device also includes a driving component that drives the first cylindrical gear 2 to rotate, and the second cylindrical gear 3 follows the rotation of the first cylindrical gear 2, causing the ring-shaped reinforcing bar 21 to rotate.

[0022] This invention is applicable to the process of generating ring-shaped reinforcing bars 21 using equipment such as ring-shaped reinforcing bar forming machines or fully automatic reinforcing bar bending and forming machines, for driving the generated ring-shaped reinforcing bars 21. During the generation of the ring-shaped reinforcing bars 21, the front end of the ring-shaped reinforcing bars 21 passes through the annular groove 4 of the first cylindrical gear 2 and the second cylindrical gear 3. The inner walls of the annular groove 4 of the first cylindrical gear 2 and the second cylindrical gear 3 together clamp the ring-shaped reinforcing bars 21. The driving component drives the first cylindrical gear 2 to rotate, and the second cylindrical gear 3 follows the rotation of the first cylindrical gear 2. The rotation of the first cylindrical gear 2 and the second cylindrical gear 3 causes the ring-shaped reinforcing bars 21 to spiral forward, thereby providing power for the rotation of the ring-shaped reinforcing bars 21, reducing the burden on the ring-shaped reinforcing bar forming machine, so that when the ring-shaped reinforcing bar forming machine generates longer ring-shaped reinforcing bars 21, even if the weight is large, it can still complete the continuous pushing of the ring-shaped reinforcing bars 21. Multiple main frames 1 are connected to form a whole under the connection structure, and the multiple main frames 1 are fixed in a fixed state by the fixing components. During the driving of the annular steel bar 21, the stability of the multiple main frames 1 can be maintained. Secondly, the first cylindrical gear 2 and the second cylindrical gear 3 on the main frame 1 drive the annular steel bar 21 in a clamping manner. The multiple main frames 1 complete the clamping at multiple points, so that the spiral forward trajectory of the annular steel bar 21 is limited, ensuring the stability during the spiral forward process.

[0023] Furthermore, the drive assembly includes a first drive motor 5 mounted on the main frame 1. The output shaft of the first drive motor 5 is fixedly connected to a through shaft 6. One or more vertical bearings 7 are mounted on the through shaft 6, and all vertical bearings 7 are fixedly connected to the main frame 1. A first bevel gear 8 is fixedly mounted on the through shaft 6, and a second bevel gear 9 is coaxially connected to a first cylindrical gear 2. The first bevel gear 8 and the second bevel gear 9 mesh. The first drive motor 5 drives the through shaft 6 and the first bevel gear 8 to rotate, which in turn drives the second bevel gear 9 and the first cylindrical gear 2 to rotate.

[0024] Furthermore, the specific structure of the rotatable first cylindrical gear 2 and second cylindrical gear 3 on the main frame 1 is as follows: a first mounting bracket 10 and a second mounting bracket 11 are installed on the main frame 1. The first cylindrical gear 2 is rotatably mounted on the first mounting bracket 10. A spring holder 12 is fixedly installed on the second mounting bracket 11. The spring holder 12 has a horizontal through hole, and a horizontally sliding slide rod 13 is connected inside the through hole. One end of the slide rod 13 is connected to a sliding seat 15. A spring 14 is sleeved on the slide rod 13. One end of the spring 14 is connected to the spring holder 12, and the other end of the spring 14 is connected to the sliding seat 15. A bearing is installed on the sliding seat 15, and the second cylindrical gear 3 is connected to the bearing. The annular groove 4 designed for the first cylindrical gear 2 and the second cylindrical gear 3 is to increase the contact surface with the annular steel bar 21. The first cylindrical gear 2 and the second cylindrical gear 3 surround the annular steel bar 21, thereby achieving a better driving effect. However, this also brings the problem that the main frame 1 is not convenient to remove directly in the vertical direction. The above-described structure in this embodiment is designed to address the problem that the main frame 1 is not easily removed vertically. The second cylindrical gear 3 is connected to the spring holder 12 and the second fixed frame via the slide rod 13 and the spring 14. During the upward lifting of the main frame 1, the second cylindrical gear 3 compresses the spring 14 under the action of the compressive force, thereby creating a gap between the first cylindrical gear 2 and the second cylindrical gear 3, allowing the main frame 1 to be smoothly removed from the annular steel bar 21. During the removal process, the first cylindrical gear 2 cannot move, but the annular steel bar 21, after being laid, has a degree of freedom of movement in the axial direction (after the annular steel bar 21 is laid, the annular steel bar forming machine is disconnected from the annular steel bar 21). The compression of the annular steel bar 21 by the first cylindrical gear 2 causes the annular steel bar 21 to move horizontally in a small amplitude in the axial direction to complete the removal; or, during the removal of the main frame 1, there is space for the main frame 1 to move slightly horizontally (manually or mechanically). As long as the first cylindrical gear 2 and the second cylindrical gear 3 leave a gap, the removal can be completed.

[0025] like Figure 4 As shown, furthermore, the through shaft 6 is provided with a plurality of first bevel gears 8, and correspondingly connected to a plurality of second bevel gears 9; a first bevel gear 8, a second bevel gear 9, a first mounting bracket 10, a second mounting bracket 11, a first cylindrical gear 2, and a second cylindrical gear 3 form a driving unit, and a main frame 1 is provided with a plurality of driving units. A main frame 1 having a plurality of driving units can increase the driving force and improve the stability of clamping.

[0026] Furthermore, the connecting structure is a connecting rod 17, which is connected to multiple main frames 1 via multiple first telescopic cylinders 16. One end of the connecting rod 17 is connected to the vehicle body 20. The fixing component is a stabilizing bracket 18, which is connected to the other end of the connecting rod 17. The stabilizing bracket 18 is equipped with one or more second telescopic cylinders 19, with the piston rods of the second telescopic cylinders 19 facing downwards to support the connecting rod 17. The multiple first telescopic cylinders 16 connected to the multiple main frames 1 allow the first telescopic cylinders 16 to be used as the driving force during the removal of the main frame 1. The stabilizing bracket 18 is used to fix the connecting rod 17, keeping the connecting rod 17 and the main frame 1 in a fixed state, ensuring the stable operation of the first cylindrical gear 2 and the second cylindrical gear 3.

[0027] like Figure 6 As shown, further, it also includes a pair of parallel idler rollers 22 and an I-beam 23. The idler rollers 22 are placed at the bottom of the ring-shaped rebar, and one end of the idler rollers 22 is connected to a second drive motor. The idler rollers 22 are used to drive the ring-shaped rebar 21 forward. Multiple brackets 24 are installed on the top of the I-beam 23, and two or more rollers 25 are installed on each bracket. The idler rollers 22 are placed on the brackets 24, and the idler rollers 22 abut against the rollers 25 of the brackets 24. The second drive motor drives the idler rollers 22 to rotate, thereby providing forward power for the ring-shaped rebar 21. The idler rollers 22 can assist in providing forward power for the ring-shaped rebar 21 in conjunction with the ring-shaped rebar forming machine and the drive assembly. The idler rollers 22 can also provide support for the ring-shaped rebar 21, reducing the pressure on the main frame 1 supporting the ring-shaped rebar 21. The idler rollers 22 rotate between two rollers 25, which can reduce friction during rotation. The bottom of the I-beam 23 is erected on the ground for use.
