Description

Track wheel rail of excavator

Technical Field

The utility model relates to a mechanical engineering technical field is a track wheel rail of digging machine particularly.

Background

With the development and progress of the times, the excavator becomes an indispensable machine in railway engineering construction. In the traditional operation of the railway, the upper track of the excavator rides on the steel rail for construction, the rail is easy to fall off, incline and turn on one's side, potential safety hazards exist, and safety accidents are easy to cause. The excavator is constructed through the track fixed point or is constructed the activity to a small extent, when long distance construction along the route, the excavator can only creep along the track slowly. If the direction is inclined or the excavator runs on a curve in a running project, the excavator is easy to fall off the track, the steel rail is easy to scratch after the track is fallen off, and the time is wasted when the excavator is re-used for running the track.

After the ballast track bed line is laid, when existing railway equipment is transformed, the common sleeper needs to be replaced by the capacitance sleeper or the sleeper is damaged and needs to be replaced, manual work is mainly relied on, construction time is long, and efficiency is low. The excavator buckets on the market are wide and are not suitable for cleaning. The excavator suitable for running on the rail is developed, and the excavator has a wide prospect for improving the railway construction efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to solve the problem that above-mentioned prior art exists, design a track wheel rail of digging machine from this, a track wheel rail of digging machine include the wheel set device, be equipped with at least one dead lever on the wheel set device, the dead lever be used for connecting the hydraulic lifting system who digs the machine, the wheel set device in be equipped with the shaft, the shaft both ends are equipped with the wheel, the lateral surface of wheel be formed with wheel tread and rim for cooperate with the rail, performance guide effect.

The utility model discloses still have following preferred technical scheme:

furthermore, the top of the wheel set device is provided with a positioner, and the positioner and the fixed rod are positioned on the same side.

Furthermore, the bottom of the wheel set device is provided with a pilot.

Compared with the prior art, the utility model, its advantage lies in: by developing the wheel set of the excavator, the wheel set is lifted by a hydraulic lifting system, so that the excavator has the condition of walking on the common ground and the common rail. The method is suitable for the complex site environment of railway construction. Particularly, for the construction of replacing the sleeper in the inner point of a business line point, the working efficiency is greatly improved, the human resource investment is reduced, the cost is reduced, the cashing of the construction task in the point is ensured, and the risk of personal labor safety is reduced. Has wide popularization prospect.

in the figure: 1. the device comprises a fixed rod 2, a wheel set device 3, a positioner 4, a barrier removal device 5, a wheel flange 6, a wheel tread 7 and a wheel shaft.

Detailed Description

The above technical solution is complied with, the following provides the specific embodiments of the present invention, and the following combines the embodiments to make further detailed description of the present invention.

Referring to fig. 1, 2, 3 and 4, the structure of the present invention is as follows:

the utility model discloses a track wheel rail of excavator, the track wheel rail of excavator structurally comprises wheel set device 2, locator 3 and pilot 4, wheel set device 2 on be equipped with at least one dead lever 1, dead lever 1 be used for connecting the hydraulic lifting system of excavator, wheel set device 2 in be equipped with shaft 7, the both ends of shaft 7 still are equipped with the wheel, the lateral surface of wheel forms wheel tread 6 and rim 5; the positioner 3 is arranged at the top of the wheel set device 2 and is positioned at the same side with the fixed rod 1; the obstacle deflector 4 is arranged at the bottom of the wheel pair device 2.

Referring to fig. 1 and 2, the using steps of the present invention are as follows:

when the excavator runs on the ground, the wheel set device 2 can be lifted through the hydraulic lifting system, so that the wheel set device 2 is in a suspended state, and the normal use of the excavator is not influenced. After the excavator is arranged on a line, wheels fall down through the transmission shaft of the hydraulic device in an aligning way and are placed on the steel rail, and at the moment, the wheel set device 2 plays a role in guiding. The crawler and the wheel positioner 3 are supported to ensure that the excavator is constructed on the track to prevent skidding, inclination and rollover, so that the construction safety is ensured; after the carriage is in a falling position, the height of the carriage is lifted through a hydraulic device, and the carriage wheels generate power through a transmission wheel shaft device internally provided with a motor to run on the track.

The inner width of the excavator bucket is changed into 450mm after the excavator bucket is reprocessed, the excavator bucket is suitable for arrangement of sleepers with 1667/Km lines from the front line to the departure line, the distance between the sleepers is 600mm, and the inner width of 450mm can ensure that the excavator bucket can smoothly clean ballast between the sleepers, and efficiency is not too slow due to too small excavator bucket. The method is also suitable for the sleeper arrangement with 1520 pieces/Km and 1440 pieces/Km. When the modified equipment of the excavator is used, one person and one machine are arranged for safety protection, a special person stares at a control command, and an operator needs to be trained in construction to ensure construction safety.
