Abstract
Description
Technical Field
[0001] The utility model relates to a quick replacement device for a traveling wheel set, belonging to the field of metallurgical mechanical equipment. Background Art
[0002] Due to the layout of the plant equipment, the entire molten steel treatment is done in the same span. The casting crane in the steel casting span is responsible for lifting the molten steel for the converter, refining and RH vacuum degassing processes in our plant. The utilization rate of the casting crane currently used online can reach more than 85%, but its wheel assembly has been online for more than 15 years and is about to face the problem of periodic replacement of the crane wheel assembly. The wheel assembly is separated from the track by a hydraulic jack and lifted up, which is convenient for the removal, movement and replacement of the wheel assembly. Figure 1 As shown in the figure, the wheel assembly after jacking needs to be removed from the track for replacement. It is necessary to weld a hoist on the wheel assembly, use a steam crane on the inside of the crane beam, and use a hand winch on the outside to lift the entire wheel assembly so that the wheel flange is higher than the track. Use the winch to move the wheel assembly out of the track horizontally. The whole process is labor-intensive. Normally, the maintenance time for replacing a wheel assembly takes more than 6 hours, which seriously restricts the production rhythm. In addition, the maintenance personnel need to enter the inside of the crane end beam. If the safety protection is not in place or the coordination is abnormal, there will be a great safety risk.

DETAILED DESCRIPTION
[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0014] A quick replacement device for a traveling wheel assembly in this embodiment, such as Figure 2 As shown, the wheel assembly 2 is arranged at the bottom of the crane beam body 1, and the wheel assembly 2 is arranged on the guide rail 4 arranged throughout the length. When moving, it guides the crane beam body 1. When the wheel assembly 2 is replaced, a hydraulic jack 3 is arranged under the crane beam body 1, and the hydraulic jack 3 lifts the crane beam body 1 so that the wheel assembly 2 is separated from the guide rail 4. Figure 3 As shown, the quick replacement device includes a support seat, which is mounted on a guide rail 4, and the two are perpendicular to each other. A traverse trolley 7 is arranged on the top of the support frame, and the traverse trolley 7 is arranged below the wheel assembly 2. The wheel assembly 2 is removed from the bottom of the crane beam body 1 and the removed wheel assembly is arranged on the traverse trolley 7. A horizontally arranged transmission screw 8 is passed through the traverse trolley 7, one end of the transmission screw 8 is threadedly connected to the traverse trolley 7, and a handwheel 5 is arranged on the other end of the transmission screw 8. The handwheel 5 is turned to drive the transmission screw 8 to rotate, so that the traverse trolley 7 moves forward and backward along the support seat, driving the wheel assembly 2 to move synchronously, so that the removed wheel assembly is moved to the outside of the crane beam, and then the removed wheel assembly is replaced offline by a steam crane. The new wheel assembly is then hoisted to the traverse trolley by the steam crane, and the new wheel assembly is moved to the installation position by reverse operation. The hydraulic jack 3 slowly drops to the installation position and is reassembled.
[0015] The support frame comprises a horizontally arranged support plate 11, two vertically arranged fixed ribs 10 are arranged at the bottom of the support plate 11, and the two fixed ribs 10 are symmetrically arranged on both sides of the guide rail. A support rib 9 is also arranged at the bottom of the support plate 11, and the support rib 9 and the fixed rib 10 are arranged at intervals.
[0016] This application is easy to operate and can quickly replace the wheel group, saving time and effort. The operator does not need to enter the inside of the end beam, which greatly reduces the time that personnel are exposed to high altitude without protection and improves the safety of operation.
[0017] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
