[0003] When an electric double-girder bridge crane is in use, the trolley moves along the guide rails on top of the beam via its bottom drive wheels. However, during use, debris or dust easily accumulates on the surface of the guide rails. Over time, this debris or dust can affect the operation of the bottom drive wheels of the trolley, causing the trolley to bounce during movement and thus affecting the stability of the electric double-girder bridge crane.

[0004] Therefore, this utility model provides a stable electric double-girder bridge crane to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a stable electric double girder bridge crane, which aims to solve the problem that in the existing technology, during use, some debris or dust easily adheres to the surface of the guide rail. After a long period of accumulation, this debris or dust will affect the operation of the drive wheels at the bottom of the crane trolley, causing the crane trolley to bounce during movement, thus affecting the stability of the electric double girder bridge crane during use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a stable electric double-girder bridge crane, comprising a beam, a guide rail connected to the top surface of the beam, a lifting trolley connected to the top surface of the guide rail, four sets of mounting blocks connected to the two ends of the bottom of the lifting trolley, a cleaning brush connected to the middle of the bottom surface of the mounting block, a connecting block connected to the top surface of the cleaning brush, one end of the connecting block extending into a connecting groove, the connecting groove being located at the middle of the bottom surface of the mounting block, a tube embedded in the bottom surface of the mounting block at both ends of the cleaning brush, a dust suction nozzle connected in a horizontal array on the bottom surface of the tube, and a connecting pipe connected to the top surface of the tube, the other end of the connecting pipe passing through the mounting block and connected to a three-way pipe, one end of the three-way pipe connected to the input end of a dust suction fan, the output end of the dust suction fan connected to a conveying pipe, and the other end of the conveying pipe connected to the top surface of the upright block.

[0007] As a preferred embodiment of the present invention, the connecting block is slidably connected to the mounting block via a connecting groove, and the connecting block has a "T" shaped structure.

[0008] As a preferred embodiment of the present invention, a bolt is provided through the top surface of the mounting block, and the other end of the bolt is threadedly connected to a fixing hole, which is located on the top surface of the mounting block.

[0009] In a preferred embodiment of the present invention, a stable electric double-girder bridge crane, the dust extraction fan is connected to the top surface of one side of the crane trolley, and the dust extraction fan is electrically connected to an external power source via a control switch.

[0010] As a preferred embodiment of the present invention, the vertical block is connected to the top surface of the lifting trolley at one end of the dust extraction fan, and a placement groove is provided on one side surface of the vertical block. A filter box is slidably placed inside the placement groove, and through holes are provided on both ends of the vertical block.

[0011] As a preferred embodiment of the present invention, a sealing ring is connected around the outer surface of one side of the filter box. One end of the sealing ring is engaged in the sealing groove opened on the inner surface of the placement groove. A butterfly bolt is connected through the top surface of the upright block, and the other end of the butterfly bolt is threadedly connected to the filter box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention utilizes the coordinated operation of an mounting block, a cleaning brush, a pipe body, a suction nozzle, a connecting pipe, a T-connector, and a suction fan. When the crane trolley moves on the guide rail, the cleaning brush at the bottom of the mounting block cleans the guide rail surface. During the cleaning process, the suction fan is activated, and through the T-connector and connecting pipe, the suction nozzle at the bottom of the pipe body generates suction. This suction nozzle then adsorbs the debris or dust swept up by the cleaning brush, ensuring the cleanliness of the guide rail surface and preventing the accumulation of debris or dust on the guide rail, which could cause the crane trolley to shake during operation. This ensures the stability of the electric double-girder bridge crane during use.

[0014] This invention utilizes the cooperation of a conveying pipe, a vertical block, a filter box, and a through hole. The debris or dust sucked up by the suction nozzle is transported into the vertical block through the conveying pipe. When the gas is transported outward through the through hole on the vertical block, the debris or dust in the gas is concentrated and collected by the filter box, preventing the debris or dust from falling back onto the guide rail and affecting the movement of the crane trolley.

[0023] Please see Figures 1-5This utility model provides the following technical solution: a stable electric double-girder bridge crane, including a beam 1, a guide rail 2 connected to the top surface of the beam 1, a lifting trolley 3 connected to the top surface of the guide rail 2, four sets of mounting blocks 4 connected to the two ends of the bottom end of the lifting trolley 3, a cleaning brush 5 connected to the middle position of the bottom surface of the mounting block 4, a connecting block 6 connected to the top surface of the cleaning brush 5, one end of the connecting block 6 extending into a connecting groove 7, the connecting groove 7 being opened at the middle position of the bottom surface of the mounting block 4, a tube 10 embedded in the bottom surface of the mounting block 4 at both ends of the cleaning brush 5, a dust suction nozzle 11 connected in a horizontal array on the bottom surface of the tube 10, and a connecting pipe 12 connected to the top surface of the tube 10, the other end of the connecting pipe 12 passing through the mounting block 4 and connected to a three-way pipe 13, one end of the three-way pipe 13 being connected to the input end of a dust suction fan 14, the output end of the dust suction fan 14 being connected to a conveying pipe 15, and the other end of the conveying pipe 15 being connected to the top surface of a vertical block 16.

[0024] Preferably, the connecting block 6 is slidably connected to the mounting block 4 through the connecting groove 7, and the connecting block 6 has a "T" shaped structure.

[0025] In practical use, the connecting block 6 on the cleaning brush 5 can slide in the connecting groove 7 on the mounting block 4, so that the cleaning brush 5 can be placed and separated on the mounting block 4. The cleaning brush 5 can be customized to be processed into the required shape and size for use.

[0026] Preferably, a bolt 8 is connected through the top surface of the mounting block 4, and the other end of the bolt 8 is threadedly connected to the fixing hole 9, which is located on the top surface of the connecting block 6.

[0027] In practical use, when the connecting block 6 on the cleaning brush 5 is slidably placed into the connecting groove 7 on the mounting block 4, the bolt 8 is screwed through the mounting block 4 into the fixing hole 9 on the connecting block 6, so that the position of the connecting block 6 is fixed in the connecting groove 7, and the cleaning brush 5 is fixed together with the mounting block 4 through the connecting block 6. By unscrewing the bolt 8, the connecting block 6 can be slidably separated from the connecting groove 7, so that the cleaning brush 5 can be removed from the mounting block 4 for maintenance.

[0028] Preferably, the vacuum cleaner 14 is connected to the top surface of one side of the crane trolley 3, and the vacuum cleaner 14 is electrically connected to an external power source via a control switch.

[0029] In practical use, the vacuum cleaner 14 can be controlled by a control switch. Two sets of vacuum cleaners 14 are installed on the top surface of the crane trolley 3. The operator can control the air volume of the vacuum cleaner 14 by using the control switch.

[0030] Preferably, the upright block 16 is connected to the top surface of the lifting trolley 3 at one end of the vacuum blower 14, and a placement groove 17 is provided on one side surface of the upright block 16. A filter box 18 is slidably placed inside the placement groove 17, and through holes 19 are provided on both ends of the upright block 16.

[0031] In practical use, the filter box 18 can slide in the placement groove 17 on the vertical block 16, allowing the filter box 18 to be slidably pulled out on the vertical block 16. When the filter box 18 is placed into the vertical block 16, the conveying pipe 15 delivers a mixed airflow containing dust or debris into the vertical block 16. The mixed airflow is then discharged outward from the through hole 19 on the vertical block 16. At this time, the filter box 18 in the vertical block 16 will intercept and filter the dust and debris in the mixed airflow, so that the dust and debris will be collected in the filter box 18.

[0032] Preferably, a sealing ring 20 is connected around the outer surface of one side of the filter box 18, one end of the sealing ring 20 is engaged in the sealing groove 21 opened on the inner surface of the placement groove 17, and a butterfly bolt 22 is connected through the top surface of the stand block 16, and the other end of the butterfly bolt 22 is threadedly connected to the filter box 18.

[0033] In practical use, the sealing ring 20 is made of rubber. When the filter box 18 is slid into the placement groove 17 on the upright block 16, the sealing ring 20 on the filter box 18 will also move to the position of the sealing groove 21, so that the sealing ring 20 is in the sealing groove 21 through the elastic block, thereby improving the sealing between the filter box 18 and the upright block 16 and preventing dust or debris from escaping through the placement groove 17. Secondly, when the filter box 18 is slid into the placement groove 17 on the upright block 16, the butterfly bolt 22 is inserted through the upright block 16 and screwed into the filter box 18, so that the position of the filter box 18 is fixed in the placement groove 17. When the butterfly bolt 22 is unscrewed, the filter box 18 can be pulled out from the placement groove 17 on the upright block 16, so that the operator can maintain the filter box 18.

[0034] Working Principle: When using this stable electric double-girder bridge crane, first, erect the beam 1 at the designated location. Then, place the lifting trolley 3 on top of the beam 1, ensuring the drive wheel at the bottom of the lifting trolley 3 contacts the guide rail 2 on the beam 1. After connecting the power supply to the lifting trolley 3, starting the drive motor in the lifting trolley 3 will cause the output end of the drive motor to drive the shaft of the drive wheel through the reducer, allowing the drive wheel to move the lifting trolley 3 along the guide rail 2. This allows the hook on the lifting trolley 3 to move to the designated position. Then, by operating the lifting mechanism on the lifting trolley 3, the drive motor drives the drum to rotate, winding or releasing the wire rope, thus raising and lowering the hook and completing the lifting and transporting of goods. While the drive wheel on the lifting trolley 3 moves along the guide rail 2, the cleaning brush 5 at the bottom of the mounting block 4 will closely adhere to the surface of the guide rail 2, cleaning dust or debris from the surface of the guide rail 2. During the process, by starting the vacuum cleaner 14, the input end of the vacuum cleaner 14 generates suction at the suction nozzle 11 on the bottom pipe body 10 of the mounting block 4 through the three-way pipe 13 and the connecting pipe 12. This suction draws the dust or debris swept up by the cleaning brush 5 into the suction nozzle 11. The suction dust or debris mixes with the air and enters the vertical block 16 through the conveying pipe 15 connected to the output end of the vacuum cleaner 14. The mixed airflow is discharged outward from the through hole 19 on the vertical block 16. At this time, the filter box 18 in the vertical block 16 intercepts and filters the dust and debris, preventing the dust or debris from falling back onto the guide rail 2 and affecting the movement of the crane trolley 3. With this setting, the crane trolley 3 can clean the guide rail 2 before it is about to be contacted during the movement, ensuring the cleanliness of the guide rail 2 and preventing the accumulation of a lot of debris or dust on the guide rail 2, which would cause the crane trolley 3 to bump during operation, thereby ensuring the stability of the electric double girder bridge crane during use.

[0035] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
