Technical Field

[0001] The invention relates to the technical field of lifting equipment, in particular to a heavy-duty bridge crane. Background Art

[0002] A bridge crane is a type of lifting equipment used to lift materials across a workshop, warehouse or material yard. The two ends of the bridge crane are located on tall concrete columns or metal supports. It is named after its bridge-like shape. When in operation, the bridge of the bridge crane runs in a straight line on the plane along the tracks laid on the elevated platforms on both sides, thereby making full use of the space under the bridge to lift materials and avoid obstruction by ground equipment, forming a type of lifting machinery with the widest range of uses and the largest number.

[0022] See also Figure 3 and Figure 4 As shown, a rotating rod 14 is arranged on the right side wall of the third gear 10 , and a moving wheel 11 is arranged on the outer sleeve of the rotating rod 14 , and the moving wheel 11 is arranged on the top surface of the running track 4 .

[0023] A friction plate 12 is provided on the left side wall of the running track 4 .

[0024] See also Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the anti-lateral deviation device 32 also includes a No. 1 fixing rod 33, which is fixedly arranged on the left side wall of the box body 5. A No. 1 electromagnet 16 is arranged on the left side wall of the No. 1 fixing rod 33, a magnetic block 17 is arranged on the middle side wall of the curved rod 7, and a No. 1 positioning sleeve 15 is arranged on the middle part of the curved rod 7 and the outer cover of the No. 1 fixing rod 33.

[0025] The anti-lateral deviation device 32 also includes a No. 2 fixing rod 24, which is fixedly arranged on the left side wall of the box body 5. A No. 2 electromagnet 23 is arranged on the left side wall of the No. 2 fixing rod 24. A spring 20 is arranged in the inner cavity at the top of the curved rod 7. A connecting rod 21 is arranged on the right side of the spring 20. A small iron ball 22 is arranged on the right side of the connecting rod 21. The left side of the connecting rod 21 is sleeved in the inner cavity at the top of the curved rod 7. A No. 2 positioning sleeve 19 is arranged on the right side of the connecting rod 21 and the outer sleeve of the No. 2 fixing rod 24.

[0026] The anti-lateral deviation device 32 also includes a No. 1 laser rangefinder 25 and a distance plate 26. Both the No. 1 laser rangefinder 25 and the distance plate 26 are arranged on the box body 5. The No. 1 laser rangefinder 25 is arranged on the anti-lateral deviation device 32 located on the left track block 2, and the distance plate 26 is arranged on the anti-lateral deviation device 32 located on the right track block 3.

[0027] The first electromagnet 16 and the magnetic block 17 are opposite to each other with the same pole.

[0028] The second gear 9 is gear-connected with the first gear 8 and the third gear 10 respectively.

[0029] In this embodiment, when the crane body 1 is in operation, the No. 1 laser rangefinder 25 detects the distance between itself and the distance plate 26 in real time. Because the distance from the top of the distance plate 26 is gradually decreasing, when the beam deviates, the anti-lateral deviation device 32 on the slower side of the beam starts the No. 2 electromagnet 23, and the No. 2 electromagnet 23 generates a primary magnetic attraction to the small iron ball 22, driving the connecting rod 21 to move toward the No. 2 electromagnet 23. At the same time, the spring 20 pulls the curved rod 7 to follow the movement of the connecting rod 21, and finally controls the No. 2 gear 9 to move toward the box 5 and mesh with the No. 1 gear 8 and the No. 3 gear 10, and then starts the motor 6, and drives the moving wheel 11 to rotate through the gear meshing, thereby accelerating the movement of one side of the beam, and the anti-lateral deviation device 32 on the faster side starts the No. 2 electromagnet 23, and the No. 2 The electromagnet 23 generates secondary magnetism to attract the small iron ball 22, driving the connecting rod 21 to move toward the second electromagnet 23. At the same time, the spring 20 pulls the curved rod 7 to follow the movement of the connecting rod 21, and drives the brake plate 13 to contact the friction plate 12. The friction provides resistance to the movement of the other side beam, and brakes the other side beam. When the second electromagnet 23 is started, the first electromagnet 16 is powered off, and the repulsive force between the first electromagnet 16 and the magnetic block 17 gradually disappears, preventing the repulsive force from affecting the meshing between the second gear 9 and the first gear 8 and the third gear 10. After the beam is straightened, the second electromagnet 23 is powered off, and the first electromagnet 16 is powered on. The first electromagnet 16 and the magnetic block 17 generate repulsive force to push the curved rod 7 away. At the same time, the curved rod 7 is affected by elasticity to pull the connecting rod 21 back to the initial state.

[0030] Example 2 See also Figure 1 and Figure 8 As shown, the crane includes a crane body 1, a left track block 2 and a right track block 3, the left track block 2 and the right track block 3 are respectively arranged on the left side and the right side of the bottom end of the crane body 1, the top surfaces of the left track block 2 and the right track block 3 are provided with running tracks 4, the anti-lateral deviation device 32 is arranged on the crane body 1, the anti-lateral deviation device 32 includes a box body 5, the box body 5 is fixedly connected to the crossbeam on the crane body 1, the top surface of the box body 5 is provided with a motor 6, the top of the motor 6 is provided with a first gear 8, the bottom of the first gear 8 is provided with a second gear 9, the left side wall of the second gear 9 is provided with a curved rod 7, the bottom side wall of the curved rod 7 is provided with a brake plate 13, and the bottom of the second gear 9 is provided with a third gear 10.

[0031] The crossbeams on the crane body 1 are divided into a left crossbeam 101 and a right crossbeam 102. A sliding sleeve rod 28 is arranged on the right side wall of the left crossbeam 101, and a distance block 31 is arranged in the inner cavity of the sliding sleeve rod 28. A sliding inner rod 29 is arranged on the left side wall of the right crossbeam 102, and a No. 2 laser rangefinder 30 is arranged in the inner cavity of the sliding inner rod 29. The sliding sleeve rod 28 is sleeved on the outer wall of the sliding inner rod 29.

[0032] In this embodiment, when the crane body 1 is in operation, if the distance between the left crossbeam 101 and the right crossbeam 102 changes, the sliding inner rod 29 will be pulled to move in the inner cavity of the sliding sleeve rod 28. At this time, the No. 2 laser rangefinder 30 detects that the distance between it and the distance block 31 has changed, and then the anti-lateral deviation device 32 on the left crossbeam 101 is braked (pushing the left crossbeam 101 to accelerate forward), and the anti-lateral deviation device 32 on the right crossbeam 102 pushes the right crossbeam 102 to accelerate forward (brake) until the distance between the left crossbeam 101 and the right crossbeam 102 returns to a normal value. At the same time, the left crossbeam 101 and the right crossbeam 102 facilitate the movement of maintenance personnel when repairing the crane body 1 at high altitude.
