An automatic leveling hydraulic device suitable for transporting ultra-high-rise precast beams. Technical Field

[0001] This utility model relates to the technical field of bridge construction, and more specifically, to an automatic leveling hydraulic device suitable for transporting precast beams in ultra-high sections. Background Technology

[0002] A beam transport vehicle is a type of mechanical equipment specifically used for transporting precast beams. It is mainly used in the bridge construction process to transport precast beams to designated locations for erection. Beam transport vehicles are usually used in precast plants or bridge sites and come in various types, such as rail-mounted and tire-mounted.

[0003] Some existing precast beam transportation devices are equipped with automatic leveling hydraulic systems. These systems use cross slope angle sensors to detect the tilt angle of the precast beams during transportation and then use hydraulic cylinders to automatically level the beams, thus preventing them from tilting. However, if the hydraulic cylinder system fails or malfunctions during the automatic leveling process, the safety of transporting precast beams in emergency situations cannot be guaranteed.

[0004] Therefore, an automatic leveling hydraulic device suitable for transporting ultra-high-rise precast beams is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an automatic leveling hydraulic device suitable for transporting ultra-high-rise precast beams, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic leveling hydraulic device suitable for transporting ultra-high-rise precast beams, comprising a beam transport vehicle, on which two connecting seats are symmetrically arranged, and a leveling bracket is arranged between the two connecting seats. A connecting shaft is fixedly threaded through the leveling bracket, and both ends of the connecting shaft are rotatably connected to the two connecting seats respectively. A rotating column is fixedly connected to one end of the connecting shaft. An angle sensor is bolted to one of the connecting seats, and the rotating shaft of the angle sensor is fixedly connected to one end of the rotating column. A gear is provided at the bottom of the leveling bracket, and a rack block meshing with the gear is provided below the gear. Hydraulic jacks are symmetrically arranged on the bottom wall of the beam transport vehicle, and the output end of the hydraulic jack is fixedly connected to the bottom wall of the rack block.

[0007] Preferably, the beam transport vehicle is bolted with an angle sensor, and two hydraulic push rods are symmetrically arranged between the beam transport vehicle and the leveling bracket. The upper and lower ends of the two hydraulic push rods are respectively connected to the beam transport vehicle and the leveling bracket through universal joints, and the universal joints are fixedly connected to the beam transport vehicle and the leveling bracket through bolts.

[0008] Preferably, the leveling bracket is equipped with a controller for receiving signals from the tilt sensor, and the controller is electrically connected to the hydraulic push rod.

[0009] Preferably, the leveling bracket has symmetrically formed grooves on its upper surface, and each of the two grooves is rotatably connected to a threaded rod. A slider is threadedly fitted on the outer side of the threaded rod, and a limiting steel plate for limiting the precast beam is fixedly connected to the top of the slider.

[0010] Preferably, servo motors are bolted to both sides of the leveling bracket, and the output ends of the servo motors are connected to one end of the threaded rod via couplings.

[0011] Preferably, a limiting steel wire rope is fixedly installed at each of the four corners of the upper surface of the leveling bracket, and the other end of the four limiting steel wire ropes is fixedly connected to the top of the precast beam.

[0012] Preferably, the upper surface of the leveling bracket is provided with four support rods, and the ends of every two support rods away from the leveling bracket are hinged to a support plate.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. Compared with existing technologies, by adding an angle sensor, abnormal rotation of the leveling bracket can be detected. The detection data is then converted into an electrical signal, which is received by a controller that is electrically connected to the angle sensor. The controller then controls the hydraulic jack to move the rack block upward. The upward-moving rack block meshes with the gear, thereby limiting and fixing the leveling bracket and the precast beam fixed on the upper surface of the leveling bracket.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] As shown in Figures 1 to 4, an automatic leveling hydraulic device suitable for transporting ultra-high-rise precast beams includes a beam transport vehicle 1. Two connecting seats 7 are symmetrically arranged on the beam transport vehicle 1, and a leveling bracket 2 is positioned between the two connecting seats 7. A connecting shaft 4 is fixedly threaded through the leveling bracket 2, and both ends of the connecting shaft 4 are rotatably connected to the two connecting seats 7 respectively. A rotating column 5 is fixedly connected to one end of the connecting shaft 4. An angle sensor 6 is bolted to one of the connecting seats 7, and the rotating shaft of the angle sensor 6 is fixedly connected to one end of the rotating column 5. A gear 3 is provided at the bottom of the leveling bracket 2, and a rack block 8 meshing with the gear 3 is provided below the gear 3. Hydraulic jacks 9 are symmetrically arranged on the inner bottom wall of the beam transport vehicle 1, and the output end of the hydraulic jacks 9 is fixedly connected to the bottom wall of the rack block 8. A controller that receives the signal from the angle sensor 6 is provided on the leveling bracket 2, and the controller is electrically connected to multiple hydraulic jacks 9, allowing control of the hydraulic jacks 9.

[0023] In use, the device first detects the rotation angle of the connecting shaft 4 and the leveling bracket 2 by fixing the rotating shaft of the angle sensor 6 to the rotating column 5. The angle sensor 6 converts the detected data into an electrical signal, which is received by the controller and compared with the data in the preset range. When the rotation of the leveling bracket 2 is detected to be too fast, the controller controls multiple hydraulic jacks 9 to drive the rack block 8 to move upward. The upward-moving rack block 8 meshes with the gear 3, thereby limiting and fixing the leveling bracket 2 and the precast beam fixed on the upper surface of the leveling bracket 2. This structure can promptly limit and stabilize the leveling bracket 2 and the precast beam set on the leveling bracket 2 when the two hydraulic push rods 11 fail or malfunction, further improving the stability of the device.

[0024] Example 2

[0025] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, as shown in Figures 1 to 4. For details, please refer to the following description:

[0026] In a preferred embodiment, an inclination sensor 10 is bolted to the beam transport vehicle 1. Two hydraulic push rods 11 are symmetrically arranged between the beam transport vehicle 1 and the leveling bracket 2. The upper and lower ends of the two hydraulic push rods 11 are connected to the beam transport vehicle 1 and the leveling bracket 2 respectively through universal joints 12. The universal joints 12 are fixedly connected to the beam transport vehicle 1 and the leveling bracket 2 by bolts. The leveling bracket 2 is equipped with a controller that receives signals from the inclination sensor 10, and the controller is electrically connected to the hydraulic push rods 11. Furthermore, in use, the device can first detect the inclination angle of the leveling bracket 2 and the precast beam set on the leveling bracket 2 through the inclination sensor 10, then convert the detection data into an electrical signal, receive the electrical signal through the controller, and then control the two hydraulic push rods 11 to quickly level the inclination angle of the leveling bracket 2 and the precast beam set on the leveling bracket 2, so as to prevent the precast beam from tilting and causing a safety accident.

[0027] In a preferred embodiment, the leveling bracket 2 has symmetrically arranged grooves 13 on its upper surface. Threaded rods 14 are rotatably connected to both grooves 13. Slider 15 is threadedly sleeved on the outer side of the threaded rods 14. A limiting steel plate 16 for limiting the precast beam is fixedly connected to the top of the slider 15. Servo motors are bolted to both sides of the leveling bracket 2, and the output ends of the servo motors are connected to one end of the threaded rods 14 via couplings. Furthermore, during use, the servo motors can drive the two threaded rods 14 to rotate and adjust. Then, the rotating threaded rods 14 drive the two sliders 15 to move the two limiting steel plates 16 toward the precast beam placed on the upper surface of the leveling bracket 2 and limit its movement, ensuring its stability during transportation.

[0028] In a preferred embodiment, a limiting steel wire rope 17 is fixedly installed at each of the four corners of the upper surface of the leveling bracket 2. The other end of the four limiting steel wire ropes 17 is fixedly connected to the top of the precast beam. Four support rods 19 are provided on the upper surface of the leveling bracket 2. The ends of every two support rods 19 away from the leveling bracket 2 are hinged to a support plate 18. Furthermore, when using the device, the precast beam can be placed on the top of the leveling bracket 2 first, and then fixedly connected to the top of the precast beam by multiple limiting steel wire ropes 17 to fix the precast beam. Then, the support rods 19 and the support plate 18 are used to further stabilize and support the precast beam, preventing it from shaking during transportation.

[0029] The working process of this utility model is as follows: First, the precast beam is placed on the top of the leveling bracket 2. Then, multiple limiting steel wire ropes 17 are fixedly connected to the top of the precast beam to fix it. Then, the supporting rod 19 and the supporting plate 18 are used to further stabilize and support the precast beam to prevent it from shaking during transportation. Then, the two threaded rods 14 are driven by a servo motor to rotate and adjust. Then, the rotating threaded rods 14 drive the two sliders 15 to drive the two limiting steel plates 16 to move towards the leveling bracket 2. The precast beams on the upper surface are brought close together and limited to further ensure their stability during transportation. At the same time, the tilt angle sensor 10 detects the tilt angle of the leveling bracket 2 and the precast beams set on the leveling bracket 2, and then converts the detection data into an electrical signal. The controller receives the electrical signal and then controls two hydraulic push rods 11 to quickly level the tilt angle of the leveling bracket 2 and the precast beams set on the leveling bracket 2, so as to prevent the precast beams from tipping over and causing safety accidents.

[0030] When the tilt angle of the leveling bracket 2 and the precast beam set on the leveling bracket 2 is rapidly adjusted, the leveling bracket 2 will rotate left and right, thereby driving the connecting shaft 4 and the rotating column 5 to rotate. At this time, the rotation angle of the connecting shaft 4 and the leveling bracket 2 is detected by the angle sensor 6. The angle sensor 6 converts the detected data into an electrical signal, and the controller receives the electrical signal and compares the data with the data in the preset value range. When the rotation of the leveling bracket 2 is detected to be too fast, the controller controls multiple hydraulic jacks 9 to drive the rack block 8 to move upward. The upwardly moving rack block 8 meshes with the gear 3, thereby limiting and fixing the leveling bracket 2 and the precast beam fixed on the upper surface of the leveling bracket 2. This structure can immediately limit and stabilize the leveling bracket 2 and the precast beam set on the leveling bracket 2 when the two hydraulic push rods 11 fail or malfunction. The above is the working principle of an automatic leveling hydraulic device suitable for transporting ultra-high-rise precast beams.
