Description

Technical Field

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

[0002] Double-girder cranes are generally composed of three major parts: mechanical, electrical and metal structures. The appearance of a bridge crane is like a single-span flat bridge that is supported at both ends on two parallel overhead tracks and moves horizontally. Double-girder cranes are widely used in indoor and outdoor industrial and mining enterprises, steel and chemical industries, railway transportation, ports and terminals, and logistics turnover departments and places. Generally, in order to facilitate the vertical and horizontal transportation of materials, electric double-girder bridge cranes are arranged near the top of the factory building.

[0003] Based on the above, the inventors found that the existing cranes are lifted by the support of a double-beam bridge and move through the slide chute on the double-beam bridge. The slide chute on the double-beam bridge needs to be cleaned frequently, otherwise it is easy to accumulate debris and dust, affecting the movement of the crane. However, the slide chute is located at a high position and manual cleaning is inconvenient. Therefore, in view of this, the existing structure is studied and improved to provide an electric double-beam bridge crane, in order to achieve a more practical purpose. Utility Model Content

[0027] Example:

[0028] See also Figure 1-5 , an electric double-beam bridge crane, comprising a support platform 1, a crane support frame 2 is slidably connected to the top surface of the support platform 1, and slide grooves 3 are provided on both sides of the support platform 1, a crane body 4 is fixedly connected to the middle of the crane support frame 2, and a double-axis motor 5 is fixedly connected to both sides of the crane support frame 2, a group of suspension ropes 6 is arranged below the crane body 4, a movable shaft 7 is arranged on one side of the double-axis motor 5, cleaning blocks 8 are arranged at both ends of the movable shaft 7, and a positioning mechanism 9 is arranged at the connection between the movable shaft 7 and the cleaning block 8, a clamping rod 10 is fixedly connected to the inner side of the cleaning block 8, and a group of positioning grooves 11 are provided on the outer side of the clamping rod 10;

[0029] The positioning mechanism 9 includes a threaded sleeve 12, one side of the threaded sleeve 12 is movably connected to a movable ring 13, the outer side of the movable ring 13 is fixedly connected to a group of extrusion blocks 14, one end of the extrusion block 14 is fitted with a pressure plate 15, both sides of the pressure plate 15 are fixedly connected with return springs 16, in order to facilitate the installation and disassembly of the cleaning block 8 and the replacement of the cleaning block 8, the positioning mechanism 9 is provided.

[0030] See also Figure 1 The two output ends of the dual-axis motor 5 and the outer sides of the opposite sides of the movable shaft 7 are both sleeved with transmission belts. The hoisting objects are first fixed by the lifting rope 6, and then the objects are driven up by the crane body 4. Then the crane support frame 2 is started to move in the lifting direction, and the dual-axis motor 5 in the moving direction is started at the same time, so that the corresponding movable shaft 7 rotates.

[0031] See also Figure 2 The cleaning block 8 is located inside the chute 3, and the movable shaft 7 is movably connected to the outer side of the crane support frame 2. The rotation of the movable shaft 7 drives the cleaning block 8 to rotate, so that the cleaning block 8 cleans the inside of the chute 3 during the movement, and cleans the dust and debris to one end of the chute 3, and falls through the inclined discharge port.

[0032] See also Figure 3 The clamping rod 10 is clamped with one end of the movable shaft 7, and a plurality of positioning grooves 11 are arranged in a ring array. The clamping rod 10 is first clamped with the movable shaft 7 so that the cleaning block 8 is located inside the slide groove 3.

[0033] See also Figure 4 The threaded sleeve 12 and the movable ring 13 are both located on the outside of the movable shaft 7, and the threaded sleeve 12 is threadedly connected to the movable shaft 7, and the movable ring 13 is slidably connected to the movable shaft 7. The threaded sleeve 12 is rotated to make the movable ring 13 slide toward the cleaning block 8.

[0034] See also Figure 4 The pressure plate 15 is slidably connected to the movable shaft 7, and one end of the return spring 16 is fixedly connected to the inner surface of the movable shaft 7. Conversely, the threaded sleeve 12 is rotated in the opposite direction so that the movable ring 13 drives the extrusion block 14 to separate from the pressure plate 15. Under the action of the return spring 16, the pressure plate 15 is separated from the positioning groove 11, and the cleaning block 8 can be removed for replacement.

[0035] See also Figure 5 The outer end of the pressure plate 15 is arranged in an inclined shape, and the inner end of the pressure plate 15 is adapted to the positioning groove 11. The movement of the movable ring 13 causes the extrusion block 14 to squeeze the outer end of the pressure plate 15, thereby causing the pressure plate 15 to slide inward and engage with the positioning groove 11, completing the fixing work of the cleaning block 8. At the same time, the movement of the pressure plate 15 compresses the return spring 16.

[0036] When in use: firstly, engage the connecting rod 10 with the movable shaft 7, so that the cleaning block 8 is located inside the slide groove 3, rotate the threaded sleeve 12, and slide the movable ring 13 toward the cleaning block 8. The movement of the movable ring 13 causes the extrusion block 14 to squeeze the outer end of the pressure plate 15, and then the pressure plate 15 slides inward and engages with the positioning groove 11, completing the fixing of the cleaning block 8. At the same time, the movement of the pressure plate 15 compresses the reset spring 16, and then the hoisting object is fixed by the lifting rope 6, and then the object is driven up by the crane body 4, and then the crane support frame 2 is started. Move in the lifting direction, and start the double-axis motor 5 in the moving direction at the same time, so that the corresponding movable shaft 7 rotates. The rotation of the movable shaft 7 drives the cleaning block 8 to rotate, so that the cleaning block 8 cleans the inside of the slide 3 during the movement, and cleans the dust and debris to one end of the slide 3, and falls through the inclined discharge port to complete the dust cleaning work, and rotate the threaded sleeve 12 in the reverse direction, so that the movable ring 13 drives the extrusion block 14 to separate from the pressure plate 15, and under the action of the reset spring 16, the pressure plate 15 is separated from the positioning groove 11, and the cleaning block 8 can be removed for replacement.
