Description

Technical Field

[0001] The utility model relates to the technical field of double-beam bridge cranes, and more specifically, to a double-beam bridge crane with a fixed electric hoist. Background Art

[0002] Double-girder bridge crane is a commonly used industrial lifting equipment, mainly used for vertical lifting and horizontal transportation of heavy objects. Double-girder bridge crane has two main beams, which are placed in parallel and bear the weight of the crane and the weight of the hoisted objects. Electric hoist fixed crane directly connects the electric hoist to the double-girder bridge bracket to achieve the effect of lifting and lowering the hoisted objects. However, most of the traditional fixed double-girder bridge cranes are connected to the double beams through hooks. This connection method will cause the electric hoist to be unstable, and it is easy to cause the hoisted objects at the lower end to swing back and forth, which will cause danger; and it does not have a self-locking mechanism. When the hoisted object is suspended in the air, the motor is subjected to a large pulling force, which will affect the service life of the motor over time. Utility Model Content

The lifting mechanism comprises a load-bearing plate 9. Both ends of the load-bearing plate 9 are fixedly connected to the mounting sleeve 5.

[0029] In this embodiment, a mounting frame 10 is fixedly provided on the upper end surface of the load-bearing plate 9, and an electric hoist body 11 is provided on the mounting frame 10. The electric hoist body 11 includes a motor 12, a winding drum 13 and a lifting rope 14. The motor 12 is located on one side of the mounting frame 10, and the winding drum 13 is rotatably installed with the mounting frame 10. The output end of the motor 12 is fixedly connected to the winding drum 13, and the lifting rope 14 is evenly wound on the outer wall of the winding drum, and a hook 15 is provided at the lower end thereof.

[0030] More specifically, the user can disassemble the support seat by bolts, and then slide the mounting sleeve 5 onto the threaded rod 4 and adjust the installation position of the lifting mechanism by turning the locking nut 8, which is convenient for later use. By setting two load-bearing beams 2 and the threaded rod 4, the lifting mechanism can be made more stable during operation. When the lifted object reaches the appropriate point, the electric push rod 16 can be controlled to make the brake block 17 contact the brake disc 18, thereby fixing the winding drum 13, reducing the tension on the motor 12 and extending its service life.

[0031] See also Figure 2 , Figure 4 and Figure 5As an implementation method for limiting the hoisted object and preventing it from falling out: a connecting rod 19 is fixedly arranged at one end of the hook 15, and a locking pin 20 is slidably arranged on the connecting rod 19.

An inclined surface is arranged at one end of the locking pin 20, and the inclined surface is located inside the locking groove 21.

[0032] Specifically, when the hoisted object enters into the hook 15, the spring 23 will push out the locking pin 20 so that one end of the locking pin enters into the locking groove 21, thereby shielding the hoisted object and preventing it from falling out.

[0033] Please refer to Figure 2 As a further implementation method for fixing the winding drum 13 , the brake block 17 and the brake disc 18 are both provided with anti-slip grooves 25 .

[0034] Specifically, the friction between the brake block 17 and the brake disc 18 can be increased.

[0035] To sum up, when the overall equipment is in use: the user can first disassemble the support seat by bolts, and then slide the mounting sleeve 5 onto the threaded rod 4 and adjust the installation position of the lifting mechanism by turning the locking nut 8, which is convenient for later use, and by setting two load-bearing beams 2 and the threaded rod 4, the lifting mechanism can be made more stable during operation, and then the load is hung on the hook 15. At this time, the spring 23 will push the locking pin 20 out so that one end of it enters the locking groove 21, thereby blocking the load and preventing it from falling out. Finally, the motor 12 is controlled to make the electric hoist body 11 work, so that the hook 15 drives the weight to rise. When the load reaches the appropriate point, the electric push rod 16 can be controlled to make the brake block 17 contact with the brake disc 18, thereby fixing the winding drum 13, reducing the tension on the motor 12 and extending its service life.
