Description

Technical Field

[0001] The present invention belongs to the field of railway maintenance equipment, and more specifically, relates to an emergency rescue device for an excavating bucket wheel. Background Art

[0002] The excavating bucket wheel of a side slope ballast cleaner is the main working device of the whole vehicle, which is used to excavate the ballast of the railway side slope. Due to its large weight and volume, large excavation depth and wide operation range, when a failure occurs and it cannot be lifted, the whole vehicle cannot be transferred on the line, seriously affecting the safety of railway operation.

[0003] The existing technology is to bind and fix the excavating bucket wheel to the rotating direction wheel through a chain, use a hydraulic jack to gradually lift the excavating bucket wheel to restore it, then bind and fix the excavating bucket wheel in the vertical direction, and finally use the hydraulic power of the vehicle itself to retract it horizontally. Since the excavating bucket wheel is a wheel structure, there is a risk of rotational overturning when using the jack to lift and restore it, and it must be reliably fixed in the rotating direction; limited by the stroke of the jack, the excavating bucket wheel needs to be reliably supported every certain distance of lifting and restoration, and then the jack needs to be readjusted to lift and restore it. At the same time, limited by the position of the jack, after the excavating bucket wheel is lifted and restored in place, it must also be vertically bound and fixed before the jack can be removed for horizontal retraction. The process is cumbersome, time-consuming, and all work is completed by manual labor, resulting in high labor intensity and high risk.

[0004] Therefore, it is expected to develop a fast, safe and reliable lifting and restoration device for the excavating bucket wheel to save time, ensure safety and reduce the manual labor intensity. Summary of the Invention

[0005] The purpose of the present invention is to provide an emergency rescue device for an excavating bucket wheel, which does not require cumbersome operations such as binding and fixing the excavating bucket wheel before and after lifting and restoration, saves time, and does not require manual operation during the lifting and restoration process, ensuring safety and reducing the manual labor intensity.

[0006] To achieve the above purpose, the present invention provides an emergency rescue device for an excavating bucket wheel. A vertical slide rail is provided on the bracket of the excavating bucket wheel, and a sliding seat sleeve is provided on the vehicle body. The excavating bucket wheel is installed on the sliding seat sleeve through the vertical slide rail and can move vertically relative to the sliding seat sleeve.

[0007] The support is installed on the sliding seat sleeve, the lifting plate is installed on the bracket of the excavator bucket wheel and is located above the support, and the hydraulic cylinder is connected between the support and the lifting plate. The lifting plate is pushed to rise by the piston rod of the hydraulic cylinder to lift the excavating bucket wheel.

[0008] Preferably, a drive assembly is further included, and the drive assembly is connected to the hydraulic cylinder through a quick-connect pipeline.

[0009] Preferably, the quick-connect pipeline includes a rubber hose and quick-connect joints arranged at both ends of the rubber hose.

[0010] Preferably, the drive assembly is an electric emergency pump. When the electric emergency pump is powered on, the piston of the hydraulic cylinder is operated through a manual control valve.

[0011] Preferably, a trunnion is provided at the bottom of the hydraulic cylinder, a slot is provided on the support, and the hydraulic cylinder is inserted into the slot through the trunnion.

[0012] Preferably, the slot is a U-shaped groove, and the support includes two pairs of vertically arranged support plates, and one such U-shaped groove is provided at the edge of the upward-facing side of each support plate.

[0013] Preferably, there are two hydraulic cylinders, the trunnions are arranged on both sides of the hydraulic cylinders, and each hydraulic cylinder is inserted into the U-shaped grooves on a pair of support plates through the trunnions.

[0014] Preferably, a groove is provided on the lower end surface of the lifting plate, the groove fits the shape of the end of the piston rod of the hydraulic cylinder, and the piston rod of the hydraulic cylinder is inserted into the groove.

[0015] Preferably, the groove is circular, oval or square.
