[0002] Automated rail cranes are efficient, reliable, and highly automated lifting equipment with a wide range of applications, playing an increasingly important role in modern industrial production. Port automated rail cranes are frequently used, operating up to M8 levels. After extended operation, the crane's trolley wheels can become out-of-round, leading to unusual noises and instability. To address these issues, workers must machine the trolley wheels to ensure the roundness and outer diameter of each wheel meet operational requirements.

[0003] Currently, workers typically repair worn rail crane trolley wheels using the following method: 1. The trolley frame is lifted and the wheels removed. This process requires extensive tooling and assembly. 2. After removal, the wheels are transported back to the machining shop, where they are machined and aligned for roundness using a lathe. 3. After machining, workers align the wheels to meet requirements for straightness, levelness, and other parameters before assembly.

The disassembly and assembly of cart wheels is difficult and the process is cumbersome, requiring the use of a large number of tools and equipment, resulting in high labor costs. 2. Using a lathe to process wheels takes a long time and is inefficient. Utility Model Content

Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0020] Please refer to the attached Figure 1-4 , combined with a specific embodiment, the following description is provided: The rail crane trolley wheel processing device described in the present utility model includes a clamping support 1. The clamping support 1 is made of I-beam, which is a conventional steel material. It not only meets the structural strength required by the device, but also is easy to obtain. A longitudinal rail bayonet 101 is provided in the middle of the bottom side of the clamping support 1. The clamping support 1 can be installed on the trolley track 2 through the rail bayonet 101 and is perpendicular to the trolley track 2. Adjustment bolts 12 are screwed to the two ends of the bottom side of the clamping support 1 through threaded through holes.

[0021] The rail bayonet 101 is provided with a clamping mechanism 3 that can clamp the trolley rail 2, thereby fixing the clamping support 1 in position on the trolley rail 2. Specifically, two clamping mechanisms 3 are provided, one at each end of the rail bayonet 101; the clamping mechanism 3 includes two fixing plates 301, which are fixed parallel to the ends of the rail bayonet 101. The fixing plates 301 are respectively fixed with clamping bolts through threaded holes.

[0022] The clamping support 1 is provided with a transverse track 4 perpendicular to the trolley track 2. The transverse track 4 is slidably connected to a fixed seat A5. The transverse track 4 is provided with an adjustment mechanism A6, which is connected to the fixed seat A5 and can adjust the lateral position of the fixed seat A5. Specifically, the transverse track 4 is 1400mm long and 300mm wide. A hollow station A401 is provided on the transverse track 4. The adjustment mechanism A6 is disposed inside the hollow station A401. The adjustment mechanism A6 includes a transmission screw A601 and a connecting block A602. The transmission screw A601 is disposed inside the hollow station A401. One end of the transmission screw A601 passes through the hollow station A401 and is screwed to the end of the transverse track 4. The connecting block A602 is fixed to the bottom side of the fixed seat A5 and is screwed to the transmission screw A601 via a threaded through hole. The transmission screw A601 and the connecting block A602 constitute the structure of the screw pair. When the staff rotates the transmission screw A601, the transmission screw A601 and the connecting block A602 cooperate to drive the fixed seat A5 to move, that is, to adjust the lateral position of the fixed seat A5.

[0023] The fixed seat A5 is provided with a longitudinal track 7 parallel to the trolley track 2, and the longitudinal track 7 is slidably connected to the fixed seat B8; the longitudinal track 7 is provided with an adjustment mechanism B9, which is connected to the fixed seat B8 and can adjust the longitudinal position of the fixed seat B8. Specifically, the longitudinal track 7 is 500mm long and 300mm wide, and a hollow station B701 is provided on the longitudinal track 7. The adjustment mechanism B9 is arranged inside the hollow station B701; the adjustment mechanism B9 includes a transmission screw B901 and a connecting block B. The transmission screw B901 is arranged inside the hollow station B701, and one end of the transmission screw B901 passes through the hollow station B701 and is screwed to one end of the longitudinal track 7. The connecting block B is fixed to the bottom side of the fixed seat B8, and the connecting block B is screwed to the transmission screw B901 through a threaded through hole. The transmission screw B901 and the connecting block B constitute the structure of the screw pair. When the staff rotates the transmission screw B901, the transmission screw B901 cooperates with the connecting block B to drive the fixed seat B8 to move, that is, to adjust the longitudinal position of the fixed seat B8.

[0024] The top side of the fixed base B8 is provided with a tool holder 10, on which a tool for machining a wheel of a large vehicle is mounted. The specific structure of the tool holder 10 and the tool can refer to the existing technology, and the staff can select the appropriate tool holder 10 and tool according to the site conditions.

[0025] The principle of operation of the present invention is as follows: The trolley track 2 is placed on the ground, without the need to remove the trolley wheels. The clamping support 1 is located in front of the trolley wheels and is mounted on the trolley track 2 via the track bayonet 101, thereby installing the device on the trolley track 2. During the installation process, the operator can adjust the clamping support 1 horizontally (X-axis, perpendicular to the horizontal direction of the track), vertically (Y-axis, parallel to the horizontal direction of the track), and horizontally (Z-axis, height direction) by adjusting the bolts 12, ultimately ensuring that the tool of the device meets the machining coordinate system reference. After adjustment, the operator clamps the trolley track 2 using the clamping mechanism 3, thereby fixing the position of the clamping support 1, thereby fixing the position of the device. Simultaneously, the operator can use the adjustment mechanism A6 to move the fixing seat A5 and the longitudinal track 7 laterally on the transverse track 4, thereby achieving axial feed processing of the trolley wheel tread; and use the adjustment mechanism B9 to move the fixing seat B8 and the tool holder 10 longitudinally on the longitudinal track 7, thereby achieving radial feed processing of the trolley wheel.

[0026] Specific processing process:

[0027] 1. Use two 50-ton hydraulic jacks to lift up both sides of the wheel frame of the trolley wheel, and put the support pads in place so that the trolley wheel is suspended in the air.

[0028] 2. Use the adjusting bolts 12 to align, position, and adjust the clamping support 1, which is the basis of the device, and use the transverse rails 4, longitudinal rails 7, tool holders 10, etc. to align the tread of the cart wheel.

[0029] 3. Turn on the raised trolley travel motor and use the trolley's own torque to rotate the trolley wheels. During the rotation process, the tool turns the trolley wheel tread, thereby achieving the processing requirements that meet the technical parameters of the trolley wheel roundness, outer diameter, etc.

[0030] 4. After processing, check the processing data to ensure that it meets the requirements, then remove this device, the lifting jack and the support tooling, and restore the trolley wheels to fall onto the trolley track 2.

[0031] In one embodiment, a fixing mechanism 11 is provided at each end of the top side of the clamping support 1, through which the transverse rail 4 can be mounted on the top side of the clamping support 1. The fixing mechanism 11 includes a connecting screw 1101 and a pressure plate 1102. The connecting screw 1101 is vertically fixed to the top side of the clamping support 1. The pressure plate 1102 is movably mounted on the connecting screw 1101 through a through hole and can press the end of the transverse rail 4. A fastening nut for tightening the pressure plate 1102 is screwed onto the connecting screw 1101. The fixing mechanism 11 achieves a detachable connection between the transverse rail 4 and the clamping support 1, facilitating assembly by personnel.
