Description

Technical Field

[0001] This utility model relates to a bridge crane positioning device, and more particularly to a bridge crane positioning device with a cleaning mechanism. Background Technology

[0002] In industrial production, bridge cranes play a vital role, responsible for moving and positioning heavy materials within the factory to ensure the smooth operation of the production process.

[0003] To ensure the accuracy and efficiency of material handling, the precise positioning function of bridge cranes is particularly crucial. However, traditional high-precision positioning devices, such as barcode positioning devices and WCS absolute coding positioning devices, lack a positioning bar cleaning device. Over long-term operation, these devices may be affected by the accumulation of dust, oil, and other industrial impurities in the tracks. These contaminants covering the positioning bars not only reduce the accuracy of the positioning system but may also lead to positioning failure, affecting the stable operation of the entire production line. Therefore, regular manual cleaning and maintenance are indispensable to maintain the normal working condition of the equipment.

[0004] However, manual maintenance is not only time-consuming and labor-intensive, but also poses safety risks when cleaning and maintenance work is carried out in some harsh or inaccessible environments.

[0005] Therefore, there is an urgent need to develop a new positioning device capable of automatically cleaning and maintaining the rails, enabling long-term stable and precise positioning of bridge cranes. This would not only improve operational efficiency and reduce maintenance costs but also enhance the safety of the entire industrial production process. The device must possess high precision, stability, and anti-interference capabilities, adapt to complex industrial environments, and reduce manual maintenance by incorporating automatic cleaning functions, thus ensuring stable production operation. Utility Model Content

[0006] To address the problem of low efficiency in manual maintenance of bridge crane tracks, this utility model proposes a bridge crane positioning device with a cleaning mechanism to replace manual maintenance of the bridge crane tracks. The technical solution is as follows.

[0007] A bridge crane positioning device with a cleaning mechanism includes a positioning vehicle and a traveling track installed on the bridge body, and a cleaning vehicle installed on one side of the positioning vehicle via a connecting structure.

[0008] The travel track consists of rails set on both sides of the bottom of the positioning vehicle, and a sensing track inside the rails. The bottom of the positioning vehicle is equipped with a sensor that works with the sensing track for positioning.

[0009] The cleaning vehicle integrates a cleaning module, a drying module, and a lubrication module on one side along the track travel direction.

[0010] The cleaning module includes a drive unit fixed to the vehicle body and a hollow rotating shaft vertically installed in the vehicle body with its lower end extending to the track surface. The drive unit rotates the hollow rotating shaft. Multiple guide keyways are axially formed on the inner wall of the hollow rotating shaft. A liftable brush rod assembly is installed in the hollow rotating shaft. The liftable brush rod assembly includes a brush rod body inserted into the hollow rotating shaft, a cleaning brush disc set at the lower end of the brush rod body, and multiple positioning keys axially set on the outer periphery of the brush rod body. The positioning keys and the guide keyways form a sliding fit. A height adjustment mechanism is also provided at the top of the brush rod body, which can fix the brush rod at a specified height in the vertical direction. A cleaning liquid supply system is also provided on one side of the cleaning vehicle, which can spray cleaning liquid onto the cleaning brush disc to improve the cleaning effect.

[0011] After the drying module dries the track cleaned by the cleaning brush, the lubrication module lubricates the track.

[0012] Furthermore, the drive device includes a drive motor fixed to the vehicle body and a reduction gearbox connected to it for transmission. A first bevel gear is coaxially mounted on the output shaft of the reduction gearbox, and a second bevel gear is coaxially fixed on the hollow rotating shaft. The first bevel gear meshes with the second bevel gear to transmit torque.

[0013] Furthermore, the height adjustment mechanism includes a pair of fixing ears disposed on both sides of the top of the hollow rotating shaft. The fixing ears are provided with fixing holes. The fixing holes of the pair of fixing ears are coaxial and the axis is perpendicular to the axis of the hollow rotating shaft. The upper part of the brush rod body is provided with several positioning holes along the axis. The brush rod body can be fixed by inserting fixing pins coaxially through the fixing holes and positioning holes.

[0014] Furthermore, the cleaning fluid supply system includes an on-board cleaning fluid tank located on one side of the cleaning vehicle, a distribution pipeline connected via a metering pump, and a nozzle array located above the cleaning brush.

[0015] Furthermore, the drying module includes a heatable fan installed in the cleaning vehicle, with the fan's outlet facing the track below the fan. Auxiliary heat dissipation vents are provided on both side walls of the cleaning vehicle to prevent heat buildup inside the cleaning vehicle. The fan's inlet is located on the top of the cleaning vehicle, and heat dissipation holes are also provided on both sides of the cleaning vehicle to prevent heat buildup from the fan.

[0016] Furthermore, the fan outlet is equipped with a fan-shaped pressurized air outlet.

[0017] Furthermore, the air inlet of the fan is equipped with a dust filter to prevent secondary contamination of the track.

[0018] Furthermore, the lubrication module includes a detachable lubricant reservoir located at the rear of the vehicle. The oil outlet of the lubricant reservoir is connected to an atomizing nozzle equipped with a solenoid valve. An electric pump is connected to the other side of the lubricant reservoir to inject air into the lubricant reservoir to maintain positive pressure inside the lubricant reservoir.

[0019] Furthermore, the connection structure includes a pair of connecting hooks respectively disposed on opposite sides of the positioning vehicle and the cleaning vehicle, and also includes a buffer disposed on opposite sides of the positioning vehicle and the cleaning vehicle to prevent the two vehicles from colliding.

[0020] The beneficial effects of this utility model are as follows: This utility model provides an automated maintenance device for bridge crane tracks that integrates positioning, cleaning, drying, and lubrication functions. Through the linkage design of the positioning vehicle and the cleaning vehicle, combined with the traveling track, the sensing track, and sensors on the bottom of the positioning vehicle, it achieves precise positioning and autonomous movement. The cleaning module uses a bevel gear-driven, liftable, rotating brush rod, along with a cleaning fluid spraying system to efficiently remove track dirt. The drying module uses a heated fan with a filter and a fan-shaped air outlet to quickly dry the track, avoiding secondary pollution. The lubrication module uses a positive pressure atomizing nozzle to evenly apply lubricant. This device, through multi-module collaborative operation, achieves full automation of track cleaning, drying, and lubrication based on precise positioning, significantly improving maintenance efficiency and quality, reducing reliance on manual labor, extending track life, and ensuring operational safety and environmental friendliness.

[0029] The present invention will be further described below with reference to the embodiments and accompanying drawings:

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, a bridge crane positioning device with a cleaning mechanism is disclosed. The positioning device includes a positioning vehicle 28 and a traveling track installed on the bridge body, and a cleaning vehicle 1 installed on one side of the positioning vehicle 28 via a connecting structure. The traveling track consists of rails 27 arranged on both sides of the bottom of the positioning vehicle 28, and a sensing track 26 inside the rails 27. A sensor 24 is provided at the bottom of the positioning vehicle 28 to cooperate with the sensing track 26 for positioning. The sensor 24 is preferably a Hall sensor 24, brand name JSMSEMI, model A3144. The sensing track 26 consists of permanent magnets arranged at equal intervals inside the rails 27, and the positive and negative poles of all permanent magnets face the same direction. The reaction principle, circuit connection, and operation logic of the sensor 24 and the positioning vehicle 28 are existing technologies, and therefore will not be described in detail here. The cleaning vehicle 1 integrates a cleaning module, a drying module, and a lubrication module on one side along the track travel direction. The cleaning module includes a drive device fixed to the vehicle body and a hollow rotating shaft 22 vertically installed in the vehicle body and extending to the track surface at its lower end. The drive device rotates the hollow rotating shaft 22. Multiple guide keyways 6 are axially formed on the inner wall of the hollow rotating shaft 22. A liftable brush rod assembly is installed in the hollow rotating shaft 22. The liftable brush rod assembly includes a brush rod body 7 inserted into the hollow rotating shaft 22, a cleaning brush disc 8 set at the lower end of the brush rod body 7, and multiple positioning keys 9 axially set on the outer periphery of the brush rod body. The positioning keys 9 form a sliding fit with the guide keyways 6. A height adjustment mechanism is also provided at the top of the brush rod body 7, which can fix the brush rod at a specified height in the vertical direction. A cleaning liquid supply system is also provided on one side of the cleaning vehicle, which can spray cleaning liquid onto the cleaning brush disc 8 to improve the cleaning effect.

[0031] After the drying module dries the walking track and sensing track cleaned by the cleaning brush 8, the lubrication module lubricates the track.

[0032] The cleaning pressure of the cleaning brush 8 on the track is changed by adjusting the height of the cleaning brush 8 to avoid insufficient or excessive cleaning force. A cleaning fluid supply system is also set on one side of the cleaning vehicle, which can spray cleaning fluid on the cleaning brush 8 to improve the cleaning effect. The drying module dries the track cleaned by the cleaning brush 8, and the lubrication module lubricates the track.

[0033] like Figure 1 , Figure 2 As shown, preferably, the drive device includes a drive motor 2 fixed to the vehicle body and a reduction gearbox 3 connected to it for transmission. The output shaft of the reduction gearbox 3 is coaxially mounted with a first bevel gear 4, and the hollow rotating shaft 22 is coaxially fixed with a second bevel gear 5. The first bevel gear 4 and the second bevel gear 5 mesh with each other. An orthogonal bevel gear set is used to convert the horizontal motor power into vertical rotational power. The structure is compact and suitable for installation in narrow spaces. The reduction gearbox 3 provides stable torque output.

[0034] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, the height adjustment mechanism includes a pair of fixing ears 10 disposed on both sides of the top of the hollow rotating shaft 22. The fixing ears 10 are provided with fixing holes 11. The fixing holes 11 of the pair of fixing ears 10 are coaxial and the axis is perpendicular to the axis of the hollow rotating shaft 22. The upper part of the brush rod body 7 is provided with a plurality of positioning holes 12 along the axis. The brush rod body 7 can be fixed by inserting fixing pins coaxially through the fixing holes 11 and positioning holes 12, so that the brush rod can be fixed at a specified height in the vertical direction. The cleaning pressure of the cleaning brush plate 8 on the track can be changed by adjusting the height of the cleaning brush plate 8 to avoid insufficient or excessive cleaning force.

[0035] like Figure 1 As shown, preferably, the cleaning fluid supply system includes an on-board cleaning fluid tank 13 located on one side of the cleaning vehicle, a distribution pipeline connected by a metering pump, and a nozzle array 14 located above the cleaning brush plate 8. The metering pump precisely controls the amount of cleaning fluid used, and the atomized spray evenly covers the cleaning brush plate 8, enhancing the cleaning effect while reducing liquid waste and avoiding excessive liquid splashing.

[0036] like Figure 1 , Figure 4As shown, preferably, the drying module includes a heatable fan 15 installed in the cleaning cart. The air outlet 16 of the fan 15 faces the track below the fan 15. Auxiliary heat dissipation vents 18 are provided on both side walls of the cleaning cart to prevent heat accumulation inside the cleaning cart. The air inlet of the fan 15 is located on the top of the cleaning cart. Heat dissipation holes 19 are also provided on both sides of the cleaning cart to prevent heat accumulation from the fan 15. Preferably, the air outlet 16 of the fan 15 is equipped with a fan-shaped pressurized air outlet 23. Hot air accelerates the evaporation of moisture on the track surface, and the fan-shaped pressurized air outlet 23 expands the drying area.

[0037] like Figure 1 Preferably, the air inlet of the fan 15 is equipped with a dust filter 17 to prevent secondary contamination of the track. The filter 17 prevents dust from being drawn in and causing secondary contamination, and assists the heat dissipation vent 18 in balancing the internal temperature of the equipment.

[0038] like Figure 1 Preferably, the lubrication module includes a detachable lubricant reservoir 20 located at the rear of the trolley. The oil outlet of the lubricant reservoir 20 is connected to an atomizing nozzle 21 equipped with a solenoid valve. An electric pump is connected to the other side of the lubricant reservoir 20 to inject air into the lubricant reservoir 20 to maintain positive pressure inside the lubricant reservoir 20. The electric pump maintains positive pressure in the lubricant reservoir 20, and works with the solenoid valve to achieve metered atomized spraying of lubricant, ensuring uniform oil film coverage. The detachable design facilitates quick replenishment or replacement of lubricant. Synthetic ester-based or perfluoropolyether lubricants are preferred. The use of lubricating oil containing magnetic particles is prohibited to prevent magnetic field interference to the permanent magnet.

[0039] like Figure 5 As shown, preferably, the sensors 24 are symmetrically mounted on both sides of the bottom of the vehicle, and each sensor 24 is covered with an alloy shield. The alloy shield is made of a high-permeability alloy, which refers to a material with a magnetic permeability of approximately 10. 2 Ferromagnetic materials, also known as soft magnetic materials, such as μ-metal high-permeability alloys.

[0040] like Figure 6 As shown, preferably, the connecting structure 29 includes a pair of connecting hooks respectively disposed on opposite sides of the positioning vehicle 28 and the cleaning vehicle 1, and also includes a buffer 30 disposed on opposite sides of the positioning vehicle 28 and the cleaning vehicle 1 to prevent the two vehicles from colliding. Preferably, the hook used in this embodiment is a close-fitting automatic hook with a self-locking mechanism. The close-fitting self-locking hook is existing technology, so it will not be described in detail here. The buffer 30 is a commercially available spring buffer.

[0041] It should also be noted that the drive of the positioning vehicle 28 involved in this utility model adopts a relatively mature solution in the prior art. The transmission structure of the drive motor 2 and the reduction gearbox 3, the torque transmission method of the bevel gear, the metering pump and the distribution pipeline control system, the heat dissipation component of the heatable fan 15, the solenoid valve controlling the atomizing nozzle 21 and the electric pump positive pressure maintenance device are all conventional technical means in this field. The linkage control logic between the lubricant tank 20 of the lubrication module and the solenoid valve, and the pipeline connection method of the cleaning fluid supply system are implemented using existing mature technical solutions, so they will not be described in detail in the specification.

[0042] It should also be noted that the lifting mechanism of the crane is a relatively mature existing technology, therefore it is not specifically described in this solution and is not marked in the attached drawings. Figure 6 The diagram only illustrates the corresponding positions of the sensor 24, the walking track, and the sensing track 26 used in this utility model.

[0043] The usage method and motion logic of this utility model are as follows: The bridge crane positioning device achieves precise positioning by cooperating with the Hall sensors 24 on both sides of the bottom of the positioning vehicle 28 and the permanent magnet induction track 26 equidistantly arranged on the inner side of the walking track. The sensors 24 adopt a high magnetic permeability alloy shield to eliminate magnetic field interference. The cleaning vehicle 1 is connected to the positioning vehicle 28 through a close-fitting self-locking hook and a spring buffer 30. It integrates cleaning, drying and lubrication modules. The cleaning module drives the hollow rotating shaft 22 to rotate through the drive motor 2 via the bevel gear set, thereby driving the liftable brush rod assembly to rotate. The height of the brush plate is adjusted by the sliding cooperation of the positioning key 9 and the guide keyway 6 and the fixing pin to control the cleaning pressure. The cleaning liquid is sprayed atomized to enhance the decontamination effect. The drying module uses a heated fan 15 in conjunction with a fan-shaped pressurized air outlet 23 to accelerate the evaporation of moisture on the track surface. The lubrication module achieves quantitative atomized spraying through the positive pressure lubricant bottle 20 and the solenoid valve linkage to ensure that the synthetic ester-based lubricant is evenly covered on the track. The entire device completes track cleaning and maintenance simultaneously during the movement, ensuring the stable operation of the positioning system.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
