Description

Technical Field

[0001] The utility model belongs to the technical field of cranes, and particularly relates to a new Chinese-style electric single-girder crane. Background Technique

[0002] The new Chinese-style crane adopts a lightweight design concept. By optimizing the structure, using high-performance components and integrating the transmission mechanism, it has good expandability. The electric single-girder crane includes an electric trolley and a main girder. The electric trolley is provided with traveling wheels, and the traveling wheels travel on the track of the main girder. When there is dust accumulation or foreign objects that are difficult to clean on the running track, it is difficult to be discovered and cleaned in time, which brings certain obstacles or dangers to the normal operation of the electric trolley. The cleaning effect of the existing cleaning device is poor, and sometimes manual cleaning is required, which is time-consuming and laborious and affects production efficiency. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the purpose of the utility model is to provide a new Chinese-style electric single-girder crane, which effectively solves the problem of poor track cleaning effect.

[0004] The technical solution for solving the technical problem is: it includes a main girder and an electric trolley. There is a track on the main girder, and traveling wheels for running along the track are installed on the electric trolley. Cleaning devices are provided on both the front and rear sides of the electric trolley. The cleaning device includes a first rotating shaft. A first bracket and a second bracket are fixed on the electric trolley. The first rotating shaft is rotatably connected between the first bracket and the second bracket. A gear is coaxially fixed on the first rotating shaft. A front-back direction rack is fixed below the track, and the rack meshes with the gear, and the rack is located above the gear. A first bevel gear located on the left side of the gear is coaxially fixed on the first rotating shaft. A second rotating shaft is rotatably connected to the first bracket. A second bevel gear meshing with the first bevel gear is coaxially fixed on the second rotating shaft. A first grinding disc contacting the upper surface of the track is coaxially fixed on the second rotating shaft. A third bevel gear located on the right side of the gear is coaxially fixed on the first rotating shaft. A third rotating shaft is rotatably connected to the second bracket. A fourth bevel gear meshing with the third bevel gear is coaxially fixed on the third rotating shaft. A second grinding disc contacting the upper surface of the track is coaxially fixed on the third rotating shaft. The first grinding disc and the second grinding disc are symmetric about the middle position of the track left and right.

[0005] Preferably, a front-back direction limiting groove is provided at the lower end of the track, and the rack is located in the limiting groove.

[0006] Preferably, a plurality of brush hairs are fixed on the outer surfaces of both the first grinding disc and the second grinding disc, and the brush hairs abut against the surface of the track.

[0007] The utility model has the following advantages compared with traditional equipment: 1) The structure is ingenious. During the operation of the electric trolley, the electric trolley drives the first rotating shaft to move back and forth. Under the meshing action of the gear and the rack, the gear drives the first rotating shaft to rotate and move back and forth. Under the meshing action of each bevel gear, the first grinding disc and the second grinding disc can be driven to rotate simultaneously to grind the surface of the track, so as to clean both the left and right sides of the guide rail, ensure the safety and stability of the running of the walking wheels, and has a high degree of automation, safety and reliability; 2) The first grinding disc and the second grinding disc do not require additional power. During the forward and backward movement of the electric trolley, the first grinding disc and the second grinding disc are automatically driven to rotate. It has low cost, good linkage and is economical and practical. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0012] The following further details the specific embodiments of the utility model in conjunction with the accompanying drawings.

[0013] By Figures 1 to 3Provided is a new Chinese-style electric single-girder crane, including a main girder 1 and an electric trolley 2. A track 3 is fixed on the main girder 1, and running wheels 4 for running along the track 3 are installed on the electric trolley 2. Cleaning devices are provided on both the front and rear sides of the electric trolley 2. The cleaning device includes a first rotating shaft 5. A first support 6 and a second support 7 are fixed on the electric trolley 2. The first rotating shaft 5 is rotatably connected between the first support 6 and the second support 7. A gear 8 is coaxially fixed on the first rotating shaft 5. A rack 9 in the front and rear direction is fixed below the track 3. The rack 9 meshes with the gear 8, and the rack 9 is located above the gear 8. A first bevel gear 10 located on the left side of the gear 8 is coaxially fixed on the first rotating shaft 5. A second rotating shaft 11 is rotatably connected to the first support 6. A second bevel gear 12 meshing with the first bevel gear 10 is coaxially fixed on the second rotating shaft 11. A first grinding disc 13 in contact with the upper surface of the track 3 is coaxially fixed on the second rotating shaft 11. A third bevel gear 14 located on the right side of the gear 8 is coaxially fixed on the first rotating shaft 5. A third rotating shaft 15 is rotatably connected to the second support 7. A fourth bevel gear 16 meshing with the third bevel gear 14 is coaxially fixed on the third rotating shaft 15. A second grinding disc 17 in contact with the upper surface of the track 3 is coaxially fixed on the third rotating shaft 15. The first grinding disc 13 and the second grinding disc 17 are symmetric about the middle position of the track 3 in the left and right directions.

[0014] In order to ensure the stability of the meshing between the gear 8 and the rack 9 and play a certain limiting role on the gear 8 to prevent the gear 8 from moving in the left and right directions, a limiting groove in the front and rear direction is provided at the lower end of the track 3, and the rack 9 is located in the limiting groove.
