[0002] A bridge crane is a lifting equipment that is horizontally mounted above a workshop, warehouse, or material yard to lift materials. Pulleys and rails are essential components of a crane. In many open-air operations, the crane rails are exposed to dust and haze for a long time, which makes the pulley and rail surfaces easily contaminated with dust. Over time, excessive dust accumulation affects the normal operation of the crane. Therefore, a bridge crane cleaning mechanism is needed to clean the dust or dirt on the crane rails.

[0003] When using a cleaning mechanism for a bridge crane, since the scraper or brush of the cleaning mechanism for a bridge crane is usually directly installed on the bottom of the vehicle body, and the height of the scraper or brush cannot be adjusted, when the vehicle body needs to be placed on the normal ground and moved, the scraper or brush will contact the ground, affecting the movement of the vehicle body. Therefore, we propose a cleaning mechanism for a bridge crane. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1

[0026] See also Figure 1-Figure 7 The utility model provides a technical solution: a cleaning mechanism for a bridge crane, comprising a body 1 and a transmission mechanism 5, wheels 2 are installed at both ends of the body 1, a placement groove 3 is opened inside the body 1, a guide rail 4 is provided under the body 1, and the transmission mechanism 5 is installed in the built-in groove of the body 1.

[0027] In specific implementation, when the guide rail 4 of the bridge crane needs to be cleaned, the vehicle body 1 can be placed on the guide rail 4, and then the vehicle body 1 drives the wheels 2 to move forward along the guide rail 4 to perform the cleaning work.

[0028] Embodiment 2

[0029] See also Figure 1-Figure 7On the basis of the first embodiment, the two ends of the transmission mechanism 5 are respectively connected with a scraper 9 and a brush 11, and the two ends of the scraper 9 and the brush 11 are connected with a support mechanism 6, and the support mechanism 6 is located in the inner wall groove of the vehicle body 1, and a positioning wheel 10 is installed in the built-in groove of the vehicle body 1 near the scraper 9. The transmission mechanism 5 includes a bidirectional electric push rod 501, a roller 502 and a trapezoidal block 503, and a bidirectional electric push rod 501 is installed in the built-in groove of the vehicle body 1. 1 is connected with rollers 502 at both ends through a movable shaft, a trapezoidal block 503 is fixed above the scraper 9 and the brush 11 near the roller 502, the supporting mechanism 6 comprises a return spring 601, a slide bar 602 and a slider 603, the two ends of the scraper 9 and the brush 11 are fixed with a slider 603, a slide bar 602 is installed in the inner wall groove of the vehicle body 1 near the slider 603, a return spring 601 is sleeved on the outer side of the slide bar 602, and the slide bar 602 and the slider 603 are slidably sleeved.

[0030] In a specific implementation, since the scraper 9 or brush 11 of the cleaning mechanism for the bridge crane is usually directly installed at the bottom end of the vehicle body 1, and the height of the scraper 9 or brush 11 cannot be adjusted, it is inconvenient to move the bottom end of the scraper 9 or brush 11 away from the guide rail 4 and move the vehicle body 1 when the scraper 9 or brush 11 is not in use. When the scraper 9 and the brush 11 are cleaning the surface of the guide rail 4, the bidirectional electric push rod 501 pushes the roller 502 to both ends, so that the roller 502 rolls on the inclined surface of the trapezoidal block 503, and the trapezoidal block 503 is squeezed to drive the scraper 9 and the brush 11 to move downward, so that the bottom ends of the scraper 9 and the brush 11 contact the guide rail 4. The scraper 9 and the brush 11 are moved on the surface of the guide rail 4, and the sliders 603 at both ends of the scraper 9 and the brush 11 slide on the slide bar 602 and squeeze the return spring 601. As the wheel 2 drives the vehicle body 1 to move, the brush 11 and the scraper 9 clean the dirt on the guide rail 4. After cleaning, the two-way electric push rod 501 drives the roller 502 to contract, so that the trapezoidal block 503 is separated from the squeezing of the roller 502, and then the return spring 601 rebounds to make the slider 603 drive the scraper 9 and the brush 11 to return to their original positions, so that the bottom ends of the scraper 9 and the brush 11 can be quickly separated from the surface of the guide rail 4, which is convenient for moving the vehicle body 1 when the guide rail 4 is not cleaned, thereby improving the convenience of the cleaning mechanism.

[0031] Embodiment 3

[0032] See also Figure 1-Figure 3 and Figure 5-Figure 8On the basis of the second embodiment, a guide groove 7 is provided at the bottom end of the placement groove 3, a collecting mechanism 8 is provided above the guide groove 7, a limit pin 12, a docking block 13 and a docking groove 15 are provided on the inner side of the collecting mechanism 8, a card block 14 is fixed on the side of the docking block 13 close to the limit pin 12, the collecting mechanism 8 includes an electric telescopic rod 801, a fixing block 802, a collecting groove 803 and a guide plate 804, a collecting groove 803 is slidably connected to the top of the guide groove 7, a guide plate 804 is connected to the side of the collecting groove 803 close to the scraper 9, and the vehicle body 1 is close to the scraper 9. An electric telescopic rod 801 is installed in the built-in groove near the placement groove 3, and a fixed block 802 is fixed on the side of the electric telescopic rod 801 close to the collecting groove 803. The limit pin 12 is installed on the side of the fixed block 802 through a movable shaft. The docking groove 15 is located on the inner side of the fixed block 802, and the docking block 13 is connected to the side of the collecting groove 803 close to the fixed block 802. The protrusion arranged under the collecting groove 803 is slidably connected to the guide groove 7, and the shape of the guide groove 7 is "7" shape. The cross-sectional shape of the docking block 13 and the docking groove 15 is "T" shape.

[0033] During specific implementation, when the scraper 9 of the cleaning mechanism of the bridge crane cleans the dirt on the surface of the guide rail 4, some dirt is sticky and adheres to one side of the scraper 9. Long-term accumulation causes the cleaning power of the scraper 9 to decrease, so that the transmission mechanism 5 and the support mechanism 6 can drive the bottom end of the scraper 9 to leave the surface of the guide rail 4, and then the electric telescopic rod 801 pushes the fixed block 802 to one side, so that the fixed block 802 pushes the collection groove 803 to drive one end of the guide plate 804 to contact one side of the scraper 9, and at the same time, the bottom end protrusion of the collection groove 803 slides in the guide groove 7, and then the scraper 9 is driven downward by the transmission mechanism 5 and the support mechanism 6. During the movement, the positioning wheel 10 is against one side of the scraper 9. The guide plate 804 and the scraper 9 move in opposite directions, and the guide plate 804 scrapes off the dirt adhered to the scraper 9 and guides it into the collection tank 803 for collection through the guide plate 804. When the collection tank 803 needs to be cleaned, the collection tank 803 is first driven back to its original position by the electric telescopic rod 801, and the limit pin 12 can be rotated to disengage the clamping block 14 of the limit pin 12, and then the collection tank 803 is pulled outward to make the bottom end protrusion of the collection tank 803 slide outward in the guide groove 7. At the same time, the collection tank 803 drives the docking block 13 to disengage the docking groove 15, which is convenient for removing the collection tank 803 from the placement groove 3 for cleaning, thereby improving the practicability of the cleaning mechanism for the bridge crane.

[0034] During actual use, the vehicle body 1 drives the wheels 2 to move on the guide rail 4, and at the same time the transmission mechanism 5 and the support mechanism 6 drive the scraper 9 and the brush 11 to clean the surface of the guide rail 4. During the cleaning process, the surface of the scraper 9 can be cleaned by the collecting mechanism 8, and the setting of the transmission mechanism 5 and the support mechanism 6 makes it convenient to separate the bottom ends of the scraper 9 and the brush 11 from the surface of the guide rail 4, which is beneficial to the movement of the vehicle body 1 on the ground, thereby improving the convenience and practicality of the cleaning mechanism for the bridge crane.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
