Split type heavy-duty vehicle pushing arm improved structure

Abstract

The invention discloses a split type heavy-duty vehicle pushing arm improved structure which comprises a pushing arm, a pushing wheel shaft and a pushing wheel; an arm internal thread drill hole is formed in the end, away from the pushing wheel, of the pushing arm; and a pushing arm internal thread is arranged in the arm internal thread drill hole. The pushing wheel shaft is composed of a pushingarm installation rod, a transition rod and a pushing wheel installation rod which are fixedly connected in sequence, wherein pushing arm external threads meshed with the pushing arm internal threads are arranged on thepushing arm installation rod, pushing wheel external threads are arranged on the pushing wheel installation rod, and a pushing wheel hole is formed in the pushing wheel, and pushingwheel internal threads meshed with the pushing wheel external threads are arranged in the pushing wheel hole. The invention has the advantages that the part purchasing cost is greatly reduced, the part processing period is short, the replacement is simple, convenient and flexible, the maintenance cost is effectively reduced, the part maintenance and replacement are convenient and flexible, the original copper sleeve transmission of the wheel is improved into bearing transmission, and the rotation is flexible.

Description

technical field [0001] The invention relates to the technical field of cart arm transformation, in particular to an improved structure of a split-type heavy cart cart arm. Background technique [0002] When the railway uses an open car to dump goods, the heavy car is first pushed into the dumper, then the open car is turned over at a certain angle to unload the goods, and then the empty car is pushed out by the empty car push device. Existing empty cart push-cart device is that traveling wheel is housed on car body, and traveling wheel rolls in track, makes car body run. The car body is provided with a cart arm, and one end of the cart arm is provided with a roller. The two ends of the car body are connected with wire ropes to connect with the hoisting traction part. When the hoisting traction part works to pull the wire rope, the car body will move along the track, so that the end of the cart arm just leans against the axle of the truck, and the truck is pushed out of the...

AI Technical Summary

Problems solved by technology

At present, there are the following problems in the empty cart pusher device of the dumper in the sintering operation area: the pusher pushes the cart forward by pushing the cart arm against the wheel axle of the train skin. During the push process, the pusher often appears The air duct of the arm handle wagon and the U-shaped tube on the wheel shaft are damaged, resulting in the failure of normal exhaust and inflation of the wagon and damage to the insurance parts of the wagon; Replace in time; the spring installed on the cart arm, due to the excessive impact force, makes the spring easy to fatigue, fail or even break. Generally, it can only be used for about two months and needs to be replaced in time

[0005] The heavy-vehicle pusher is a part of the dumper system, and it is an important mechanical part that pushes the heavy truck full of coal into the dumper. The pusher arm of the domestic heavy-vehicle pusher is cast in one piece. After the pusher arm is worn out, it can only The assembly was replaced as a whole, and the heavy-duty trolley machine often had the problem of falling off the track after running for a period of time. After careful observation and analysis, it was found that the original design and use of the wheel bearings of the original cart machine were unreasonable. The wheels use self-aligning bearings, and the shaking angle is relatively large when walking, causing deviation from the track and the problem of falling off the track

Its operational reliability directly affects the key to the smooth loading and unloading of coal wagons. The unloading time of coal wagons is too long, which leads to the overtime economic assessment of the national railway's vehicle backlog in accordance with the rules and regulations, which will cause certain economic losses to the company.
