[0038] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0039] like Figures 1 to 5As shown in the embodiment of the present invention, a bridge beam carrying device includes a receiving plate 1. A drive wheel 11 is installed on the side of the receiving plate 1. An annular drive structure 12 is provided on the annular circumferential surface of the drive wheel 11. When the drive wheel 11 rotates, it drives the annular drive structure 12 to rotate synchronously, and the annular drive structure 12 contacts the ground. A plurality of first hydraulic cylinders 13 are arranged in annular shape on the side of the drive wheel 11, and the output end of the first hydraulic cylinder 13 points away from the center of the drive wheel 11.

[0040] A support plate 14 is provided on the top surface of the receiving plate 1, and a carrying plate 15 is provided at the top of the support plate 14. The carrying plate 15 is used to carry the beam. A drive motor is provided on the side of the drive wheel 11.

[0041] In this embodiment of the invention, the cut beam is hoisted onto the carrying plate 15 using a hoisting device. Then, the drive motor connected to the drive wheel 11 is started, and the annular drive structure 12 on the drive wheel 11 contacts the ground. As the drive wheel 11 rotates, it drives the receiving plate 1 to move. The receiving plate 1, through the support plate 14, drives the beam on the carrying plate 15 to move. When the drive wheel 11 is blocked by a protruding obstacle on the ground, the operator first shuts off the drive motor, then starts the first hydraulic cylinder 13. The output end of the first hydraulic cylinder 13 extends and stops when it contacts the ground and lifts the drive wheel 11. The distance the drive wheel 11 is lifted off the ground is adjusted based on the height of the protruding obstacle. The drive motor is then restarted; the drive motor drives the drive wheel 11 to rotate further. When the drive wheel 11 rotates, it drives the first hydraulic cylinder 13 to rotate synchronously. When the first hydraulic cylinder 13 drives the output end to rotate, it passes over the protruding obstacle, or the output end of the first hydraulic cylinder 13 presses against the surface of the protruding obstacle. Then, the first hydraulic cylinder 13 and the ring drive structure 12 drive the drive wheel 11 to climb over the protruding obstacle and finally pass over it. After the entire carrying device passes over the protruding obstacle, the initial output of the first hydraulic cylinder 13 is restored, that is, the contact between the ring drive structure 12 on the drive wheel 11 and the ground is restored. The entire process of passing over the protruding obstacle only requires the operator to control the output of the first hydraulic cylinder 13, avoiding the phenomenon of the drive wheel 11 slipping when passing over the obstacle, reducing the difficulty of the carrying device passing over the protruding obstacle, and realizing the optimization of the carrying device.

[0042] like Figures 5 to 6As shown, the annular drive structure 12 is specifically an annular ring 123, which is sleeved on the annular circumferential surface of the drive wheel 11, and a pair of slots are provided on the inner annular surface; a receiving groove 121 is provided on the side of the drive wheel 11, and a second hydraulic cylinder 122 is provided inside the receiving groove 121. The output end of the second hydraulic cylinder 122 is inserted into the slot; before starting the first hydraulic cylinder 13, the second hydraulic cylinder 122 is started first, so that the output end of the second hydraulic cylinder 122 is pulled out of the slot, that is, the connection between the drive wheel 11 and the annular ring 123 is released, and then the drive wheel 11 is started. The drive motor drives the drive wheel 11 to rotate, causing the two first hydraulic cylinders 13 on the drive wheel 11 to be symmetrical about the vertical line of the wheel center. When the first hydraulic cylinder 13 is activated again, the output ends of the two first hydraulic cylinders 13, which are symmetrical about the vertical line of the wheel center, simultaneously contact the ground, thus supporting the drive wheel 11 and keeping it stable, thereby keeping the carrying plate 15 stable and facilitating the smooth carrying process. It should be noted that after the drive wheel 11 is supported, the output end of the second hydraulic cylinder 122 needs to be inserted back into the slot to facilitate the subsequent movement of the device.

[0043] like Figures 7 to 9 As shown, a pair of third hydraulic cylinders 2 are provided on the side of the output end of the first hydraulic cylinder 13. A brake block 21 is provided at the end of the output end of the third hydraulic cylinder 2. The end of the brake block 21 away from the third hydraulic cylinder 2 is set as a pointed tip. When the output end of the first hydraulic cylinder 13 presses against the surface of the protruding obstacle, and the surface of the protruding obstacle is relatively smooth, the third hydraulic cylinder 2 is activated. The output end of the third hydraulic cylinder 2 drives the pointed tip of the brake block 21 to move and insert into the surface of the protruding obstacle. When the drive wheel 11 rotates, the brake block 21 inserted into the protruding obstacle can increase the rotational torque of the drive wheel 11 when it rotates, thereby assisting the drive wheel 11 to cross the protruding obstacle.

[0044] The output end of the first hydraulic cylinder 13 has a docking groove 24, and a connecting rod 23 is inserted into the docking groove 24. A pad 22 is provided at one end of the connecting rod 23 at the groove opening. When the ground on which the device moves is relatively soft, the connecting rod 23 is inserted into the output end of the first hydraulic cylinder 13. The connecting rod 23 drives the pad 22 to be fixed to the output end of the first hydraulic cylinder 13. When the first hydraulic cylinder 13 is started, the output end of the first hydraulic cylinder 13 drives the pad 22 to press against the ground, increasing the contact area between the output end of the first hydraulic cylinder 13 and the ground, and reducing the probability that the output end of the first hydraulic cylinder 13 will sink too deep into the ground and be difficult to move. It should be noted that the top surface of the pad 22 has a hole for the brake block 21 to pass through.

[0045] like Figures 4 to 12 As shown, the top of the support plate 14 is set with an arc-shaped structure; the bottom surface of the carrying plate 15 is provided with an arc-shaped groove; when the carrying plate 15 is installed on the top of the support plate 14, the arc-shaped structure at the top of the support plate 14 is embedded in the arc-shaped groove.

[0046] A fourth hydraulic cylinder 3 is provided on the bottom surface of the receiving plate 1 and at the end position. The output end of the fourth hydraulic cylinder 3 passes through the space between the carrying plate 15 and the receiving plate 1. A sleeve 32 is provided at the top of the output end of the fourth hydraulic cylinder 3. A receiving shaft 33 is inserted into the inside of the sleeve 32. A pair of fixing plates 34 are symmetrically arranged at the bottom end of the carrying plate 15 based on the sleeve 32. The receiving shaft 33 passes through the fixing plates 34.

[0047] A sliding member 5 is provided on the side of the receiving plate 1, and a groove is formed on the side of the sliding member 5. A pair of touch switches 51 are installed symmetrically inside the groove, and a gravity block 52 is slidably connected inside the groove. A first wire is provided between the touch switches 51 and the control end of the fourth hydraulic cylinder 3. The pair of touch switches 51 control the output direction of the fourth hydraulic cylinder 3 in opposite directions. When the drive wheel 11 moves on the support of the bottom surface through the output end of the first hydraulic cylinder 13, the receiving plate 1 will inevitably tilt. The receiving plate 1 causes the carrying plate 15 to tilt, which is not conducive to maintaining the stability of the carrying. Therefore, a gravity block 52 is provided. When the receiving plate 1 tilts, the gravity block 52 slides in the groove on the sliding member 5 under the action of gravity, which controls the touch switches 51. When switch 51 is pressed, it controls the fourth hydraulic cylinder 3 to start via the first wire. A pair of fourth hydraulic cylinders 3, which are symmetrical about the center of the carrying plate 15, respectively output upward and retract downward. The output end of the fourth hydraulic cylinder 3 drives the receiving shaft 33 to move via sleeve 32. The receiving shaft 33 drives the carrying plate 15 to rotate based on the top of the support plate 14 via the fixing plate 34. The arc-shaped structure at the top of the support plate 14 and the arc-shaped groove on the bottom surface of the carrying plate 15 make the carrying plate 15 rotate smoothly. After rotation, the carrying plate 15 tilts relative to the receiving plate 1, thereby canceling the tilt angle of the receiving plate 1. That is, the carrying plate 15 continues to tend to be horizontal, reducing the probability of the beam sliding and falling off the carrying plate 15.

[0048] A fifth hydraulic cylinder 36 is provided at the end of the receiving shaft 33. The housing of the fifth hydraulic cylinder 36 is installed on the bottom surface of the carrying plate 15, and the output end is connected to the end of the receiving shaft 33. When the device moves, the fifth hydraulic cylinder 36 intermittently drives the receiving shaft 33 to move, so that the part of the receiving shaft 33 located inside the sleeve 32 is adjusted, avoiding the same part of the receiving shaft 33 from being continuously squeezed by the sleeve 32, and reducing the probability of the receiving shaft 33 bending.

[0049] Two pairs of sixth hydraulic cylinders 31 are centrally symmetrically arranged at the bottom of the receiving plate 1, with the output end of the sixth hydraulic cylinder 31 extending to the bottom surface of the carrying plate 15; each pair of sixth hydraulic cylinders 31 is symmetrical about the fourth hydraulic cylinder 3; a second wire is provided between the touch switch 51 and the control end of the sixth hydraulic cylinder 31; the sixth hydraulic cylinder 31 can support the bottom surface of the carrying plate 15, avoiding the continuous pressure on the receiving shaft 33 caused by the fourth hydraulic cylinder 3 continuously supporting the carrying plate 15, thus increasing the probability of bending; it should be noted that when the touch switch 51 is pressed, the sixth hydraulic cylinder 31 is simultaneously activated, and the output end of the adjacent fourth hydraulic cylinder 3 moves synchronously, thus avoiding obstructing the rotation of the carrying plate 15.

[0050] The top surface of the gravity block 52 is provided with a limiting groove 53, and the top surface of the sliding member 5 is provided with a seventh hydraulic cylinder 54. The output end of the seventh hydraulic cylinder 54 passes through the slide groove and can be inserted into the limiting groove 53. When the first hydraulic cylinder 13 is not activated, the output end of the seventh hydraulic cylinder 54 is inserted into the limiting groove 53 to restrict the position of the gravity block 52 in the slide groove. This prevents the gravity block 52 from moving in the slide groove due to inertia during normal start-up or braking of the device, which would then squeeze the touch switch 51 and activate the fourth hydraulic cylinder 3, causing the carrying plate 15 to rotate, which is not conducive to the stable operation of the carrying process.

[0051] like Figure 3 , Figure 14 As shown, the top surface of the transport plate 15 is provided with two pairs of mounting slots 4, and each pair of mounting slots 4 is provided with multiple slots; the inside of the mounting slot 4 is provided with a plug-in block 41, the top of the plug-in block 41 is located above the top surface of the transport plate 15 and the top is set as a pointed tip; when the beam is placed on the transport plate 15, the surface of the beam will be inserted by the tip of the plug-in block 41. When the transport plate 15 rotates, the plug-in block 41 inserted into the beam will restrict the movement of the beam relative to the transport plate 15, further improving the stability of the transport.

[0052] The top surface of the carrying plate 15 has a pair of connecting grooves 42, which are connected to the mounting groove 4; the interior of the connecting grooves 42 has multiple through holes 43; the bottom surface of the carrying plate 15, directly below the through holes 43, has a jet nozzle 44, the output end of which is connected to the through hole 43; the end of the jet nozzle 44 has an air pump 45, which is connected to the input end of the jet nozzle 44; when the plug-in block 41 is inserted into the beam, concrete dust will fall from the beam, and the air pump 45 will be activated. 5. Air is injected into the through hole 43 in the connecting groove 42 through the jet head 44. The airflow enters the connecting groove 42. Since the connecting groove 42 is connected to the mounting groove 4, the airflow will drive the dust in the mounting groove 4 away from the mounting groove 4. When the airflow acts on the bottom surface of the beam, it will surge to all sides after being reflected by the beam. Finally, the dust will be driven away from the carrying plate 15 through the gap between the beam and the carrying plate 15, which improves the cleanliness of the top surface of the carrying plate 15 when the device is used, and helps to reduce the cleaning intensity of the workers afterward.

[0053] During operation, the cut beam is hoisted onto the carrying plate 15 using a hoisting device. Then, the drive motor connected to the drive wheel 11 is started, and the annular drive structure 12 on the drive wheel 11 contacts the ground. As the drive wheel 11 rotates, it moves the receiving plate 1, which in turn moves the beam on the carrying plate 15 via the support plate 14. When the drive wheel 11 is blocked by a protruding obstacle on the ground, the operator first shuts off the drive motor, then starts the first hydraulic cylinder 13. The output end of the first hydraulic cylinder 13 extends and stops when its end contacts the ground and lifts the drive wheel 11. The distance the drive wheel 11 is lifted off the ground is adjusted based on the height of the protruding obstacle. The drive motor is then restarted, causing the drive wheel 11 to rotate further. As the drive wheel 11 rotates, it drives the first hydraulic cylinder 13 to rotate synchronously. When the output end of the first hydraulic cylinder 13 rotates, it passes over the protruding obstacle, or the output end of the first hydraulic cylinder 13 presses against the surface of the protruding obstacle. Afterward, the first hydraulic cylinder 13 and the annular drive structure 12 drive the drive wheel 15. Wheel 11 climbs over the raised obstacle and finally passes it. After the entire carrying device passes the raised obstacle, the initial output of the first hydraulic cylinder 13 is restored, that is, the contact between the annular drive structure 12 on the drive wheel 11 and the ground is restored. Before starting the first hydraulic cylinder 13, the second hydraulic cylinder 122 is started first, causing the output end of the second hydraulic cylinder 122 to withdraw from the slot, that is, to disconnect the drive wheel 11 from the annular ring 123. Then, by starting the drive motor, the drive motor drives the drive wheel 11 to rotate, so that the two first hydraulic cylinders 13 on the drive wheel 11 are symmetrical about the vertical line of the wheel center. When the first hydraulic cylinder 13 is started again, the output ends of the two first hydraulic cylinders 13 symmetrical about the vertical line of the wheel center simultaneously contact the ground. Then, the drive wheel 11 is supported and kept stable, thereby keeping the carrying plate 15 stable, which is conducive to the smooth progress of the carrying process. It should be noted that after the drive wheel 11 is supported, the output end of the second hydraulic cylinder 122 needs to be inserted back into the slot to facilitate the subsequent movement of the device.

[0054] When the output end of the first hydraulic cylinder 13 presses against the surface of the protruding obstacle, and the surface of the protruding obstacle is relatively smooth, the third hydraulic cylinder 2 is activated. The output end of the third hydraulic cylinder 2 drives the tip of the brake block 21 to move and insert into the surface of the protruding obstacle. When the drive wheel 11 rotates, the brake block 21 inserted into the protruding obstacle can increase the rotational torque of the drive wheel 11, thereby assisting the drive wheel 11 to cross the protruding obstacle. When the ground on which the device moves is relatively soft, the connecting rod 23 is inserted into the end of the output end of the first hydraulic cylinder 13. The connecting rod 23 drives the pad 22 to be fixed to the end of the output end of the first hydraulic cylinder 13. When the first hydraulic cylinder 13 is activated, the end of the output end of the first hydraulic cylinder 13 drives the pad 22 to press against the ground, increasing the contact area between the end of the output end of the first hydraulic cylinder 13 and the ground, reducing the probability that the end of the output end of the first hydraulic cylinder 13 sinks too deep into the ground and is difficult to move. It should be noted that the top surface of the pad 22 has a hole for the brake block 21 to pass through. When the support plate 1 moves via the output end of the first hydraulic cylinder 13, it inevitably causes the support plate 1 to tilt. The support plate 1 causes the carrying plate 15 to tilt, which is not conducive to maintaining the stability of the carrying process. Therefore, a gravity block 52 is set. When the support plate 1 tilts, the gravity block 52 slides in the groove on the sliding member 5 under the action of gravity, which squeezes the touch switch 51. The touch switch 51 controls the fourth hydraulic cylinder 3 to start through the first wire. Based on the central symmetry of the carrying plate 15, a pair of fourth hydraulic cylinders 3 respectively output upward and... As the cylinder contracts downwards, the output end of the fourth hydraulic cylinder 3 drives the receiving shaft 33 to move through the sleeve 32. The receiving shaft 33 drives the carrying plate 15 to rotate based on the top of the support plate 14 through the fixing plate 34. The arc-shaped structure at the top of the support plate 14 and the arc-shaped groove on the bottom surface of the carrying plate 15 make the carrying plate 15 rotate smoothly. After rotation, the carrying plate 15 tilts relative to the receiving plate 1, thereby canceling the tilt angle of the receiving plate 1. That is, the carrying plate 15 continues to tend to be horizontal, reducing the probability of the beam sliding and falling off the carrying plate 15.

[0055] During device movement, the fifth hydraulic cylinder 36 intermittently moves the receiving shaft 33, adjusting the portion of the receiving shaft 33 located inside the sleeve 32 to prevent the same portion of the receiving shaft 33 from being continuously squeezed by the sleeve 32. The sixth hydraulic cylinder 31 supports the bottom surface of the carrying plate 15, preventing the receiving shaft 33 from being continuously pressured and increasing the probability of bending due to continuous support from the fourth hydraulic cylinder 3. It should be noted that when the touch switch 51 is pressed, the sixth hydraulic cylinder 31 is simultaneously activated, moving its output end synchronously with the adjacent fourth hydraulic cylinder 3 to avoid obstructing the rotation of the carrying plate 15. When the first hydraulic cylinder 13 is not activated, the output end of the seventh hydraulic cylinder 54 is inserted into the limiting groove 53, restricting the position of the gravity block 52 within the slide groove. This prevents the gravity block 52 from moving within the slide groove due to inertia during normal device startup or braking, thus squeezing the touch switch 51 and activating the fourth hydraulic cylinder 3. The rotation of the transport plate 15 is detrimental to the stability of the transport. When the beam is placed on the transport plate 15, the tip of the insertion block 41 is inserted into the surface of the beam. When the transport plate 15 rotates, the insertion block 41 inserted into the beam restricts the movement of the beam relative to the transport plate 15, further improving the stability of the transport. When the insertion block 41 is inserted into the beam, concrete dust will fall from the beam. The air pump 45 is started, and the air pump 45 inflates the through hole 43 in the connecting groove 42 through the jet nozzle 44. The airflow enters the connecting groove 42. Since the connecting groove 42 is connected to the mounting groove 4, the airflow will drive the dust in the mounting groove 4 out of the mounting groove 4. When the airflow acts on the bottom surface of the beam, it will surge in all directions after being reflected by the beam. Finally, the dust will be driven out of the transport plate 15 through the gap between the beam and the transport plate 15, improving the cleanliness of the top surface of the transport plate 15 when the device is used, which helps to reduce the cleaning intensity of the workers afterward.
