[0001] The utility model relates to the technical field of cranes, in particular to a three-beam four-rail type hook bridge crane. Background Technique

[0002] A bridge crane is a lifting equipment that spans over workshops, warehouses, and yards for material lifting. Since its two ends are located on tall cement columns or metal brackets, it resembles a bridge. The bridge of the bridge crane runs longitudinally along the tracks laid on both sides of the elevated racks, and can make full use of the space under the bridge to lift materials without being hindered by ground equipment. It is the most widely used and the most numerous type of lifting machinery.

[0003] In the existing three-beam four-rail type hook bridge crane, the lifting trolley is not easy to disassemble, repair, and replace after long-term use, and its practicability is poor. Moreover, in the existing three-beam four-rail type hook bridge crane, the wheels of the lifting trolley run inside the track groove. When there is too much dust and debris in the track groove, it is not easy to remind the staff to clean the dust and debris in the track groove in time to avoid affecting the movement of the lifting trolley. Now, a three-beam four-rail type hook bridge crane is invented to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] Embodiment 1

[0027] Please refer to Figures 1 to 4, the present utility model provides a technical solution: a three - beam four - rail type hook bridge crane, including a main beam 1, a hoisting trolley 2 and a guide plate 3. The wheels of the hoisting trolley 2 are located inside the track groove. The sides of the triangular push plate 19 are respectively in contact with the inner side wall and the inner bottom wall of the guide rail groove. Guide chutes are provided on both the front and the rear of the main beam 1 with the front - rear direction as the depth direction and the left - right direction as the length direction. One end of the guide plate 3 away from the positioning block 12 is located inside the guide chute, and the guide plate 3 can slide along the length direction of the guide chute. End beams 4 are installed at both ends of the main beam 1. Adjustment boxes 5 are installed on both the front and the rear of the hoisting trolley 2. Positioning chutes are provided inside the adjustment boxes 5 with the up - down direction as the depth direction and the left - right direction as the length direction. The end of the positioning slider 9 is located inside the positioning chute, and the positioning slider 9 can slide along the length direction of the positioning chute. A positioning groove is provided on the front of the adjustment box 5 with the front - rear direction as the depth direction. The end of the positioning block 12 is inserted into the positioning groove. A limiting spring 6 is installed inside the adjustment box 5. One end of the limiting spring 6 is provided with an adjustment plate 7. Limiting rods 8 are installed on both the top and the bottom of the adjustment plate 7. One end of the limiting rod 8 close to the iron block 11 is inserted into the limiting groove. The iron block 11 and the magnetic block 13 are magnetically connected. A positioning slider 9 is installed on the side of the limiting rod 8 away from the adjustment plate 7. A pulling plate 10 is installed at one end of the limiting rod 8, and an iron block 11 is installed at the other end of the limiting rod 8. One end of the guide plate 3 is provided with a positioning block 12. Limiting grooves are provided on both sides of the positioning block 12, and magnetic blocks 13 are installed inside the limiting grooves.

[0028] During use, lift a heavy object through the electric hoist 22. The hoisting trolley 2 moves inside the track groove, and the guide plate 3 moves along with the movement of the hoisting trolley 2, so that the guide plate 3 moves along the length direction of the guide chute. When disassembling the hoisting trolley 2, pull the pulling plate 10, so that the limiting rod 8 drives the positioning slider 9 and the iron block 11 to move, so that the positioning slider 9 moves along the length direction of the positioning chute, so that the limiting spring 6 is stressed and contracts, so that the iron block 11 is separated from the magnetic block 13, so that the limiting rod 8 leaves the limiting groove. Then move the guide plate 3, so that the positioning block 12 leaves the positioning groove, so that the guide plate 3 leaves the guide chute. Then move the hoisting trolley 2 upward, so that the wheels of the hoisting trolley 2 leave the track groove, which is convenient for disassembling the hoisting trolley 2. On the contrary, during installation, move the hoisting trolley 2, so that the wheels of the hoisting trolley 2 and the triangular push plate 19 both enter the track groove. When the triangular push plate 19 is in contact with the inner bottom wall of the track groove, at this time, move the guide plate 3, so that the end of the positioning block 12 is inserted into the positioning groove, so that the end of the guide plate 3 enters the guide chute. When the end of the positioning block 12 reaches the end of the positioning groove, at this time, the limiting groove is aligned with the limiting rod 8. Release the pulling plate 10. Through the elastic tension of the limiting spring 6, the end of the limiting rod 8 is inserted into the limiting groove, so that the iron block 11 and the magnetic block 13 are magnetically connected, improving the stability of restricting the position of the positioning block 12, facilitating the installation of the hoisting trolley 2 and improving the practicability.

[0029] Embodiment 2

[0030] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a three-beam four-rail type hook bridge crane. L-shaped plates 14 are installed on both side surfaces of the hoisting trolley 2. A fixed block 15 and a contact switch 16 are respectively installed on one side surface of the L-shaped plate 14. A T-shaped chute with the vertical direction as the depth direction and the horizontal direction as the length direction is opened at the bottom of the fixed block 15. A return spring 17 is installed inside the T-shaped chute. One end of the return spring 17 is installed with a T-shaped slider 18. The end of the T-shaped slider 18 is located inside the T-shaped chute. The T-shaped slider 18 can slide along the length direction of the T-shaped chute. The position of the fixed block 15 is higher than the position of the contact switch 16. A triangular push plate 19 is installed at the bottom of the T-shaped slider 18. A contact block 20 is installed on one side surface of the T-shaped slider 18. The position of the contact block 20 corresponds to the position of the contact switch 16. The contact switch 16, the alarm 21, the hoisting trolley 2 and the electric hoist 22 are all electrically connected to an external power supply through wires. An alarm 21 is installed on the top of the hoisting trolley 2. A guide rail groove is opened at the top of the main beam 1. An electric hoist 22 is installed at the bottom of the hoisting trolley 2.

[0031] During use, as the hoisting trolley 2 moves, the triangular push plate 19 pushes the dust and sundries in the track groove. When there is too much dust and sundries accumulated in front of the triangular push plate 19, a certain resistance is formed, causing the triangular push plate 19 to move relative to the hoisting trolley 2, making the T-shaped slider 18 slide along the length direction of the T-shaped chute, causing the return spring 17 to be stressed and contract. The position of the contact block 20 corresponds to the position of the contact switch 16. When the contact block 20 abuts against the contact switch 16, the alarm 21 sounds at this time, which is convenient to remind the surrounding staff to clean the dust and sundries in the track groove in time, avoiding affecting the movement of the hoisting trolley 2 and improving the practicability.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
