A METHOD FOR ARRANGING ROLLING-FRICTION EXTENDING AND
RETRACTION BASED ROLLING STROKE SECTION OF A ROCKER ARM IN
PARALLEL, AND AN EXCAVATOR OR LOADER COMPRISING A ROCKER ARM
HAVING ROLLING STROKE SECTIONS IN PARALLEL
Technical field The present invention relates to the field of excavators or loaders, and in particular, to a method for arranging rolling-friction extending and retraction based rolling stroke sections of a rocker arm in parallel, and an excavator or loader comprising a rocker arm having rolling stroke sections arranged in parallel.
Background The rocker arms of commonly used equipment such as heading machines or coal mining machines or loading machines, for example, the rocker arms of reciprocating impact heading machines or the rocker arms of reciprocating impact coal mining machines or the rolling harrow support rocker arms of rolling-harrow loading machines, all extend and retract relative to the machine bodies by means of sliding friction, resulting in high sliding friction resistance and strong twisting force. In order to improve work efficiency and applicability, the work heads of the heading machine, the coal mining machine, the loading machine and the like are designed to have large volume and great weight. The work heads having large volume and great height produce great twisting gravity and serious reciprocating wear onto the telescopic sliding guide rail; moreover, in operation, crawling jitters are easy to occur, and in serious cases, bonding burn may appear in the sliding friction surface. The most critical thing is that the adjustment to the movement fails because it is difficult to form a uniform lubricating oil film on the friction surface thereof to generate heat by friction owing to the particularity of working environment. In order to avoid extending/retracting and sliding friction faults of the rocker arms, many manufacturers do not use telescopic rocker arms. However, service efficiency and adaptability are seriously reduced by forbidding the rocker arm to extend or retract relative to the machine body. In some cases, the slide rail is shortened in order to reduce sliding frictional resistance, but this would result in problems such as short rocker arm extending/retracting distance, small excavation or loading range, bad adaptability, and low operating efficiency, etc. Furthermore, the service efficiency and adaptability will be more seriously reduced if the rocker arm is forbidden to extend or retract relative to the machine body. In order to solve the above problems, rolling friction is used in the present invention to reduce wear and frictional resistance, and more especially, the rolling stroke sections of the rollers are arranged in parallel. Therefore, the present invention provides a method for arranging rolling-friction extending and retraction based rolling stroke sections of a rocker arm in parallel, and an excavator or loader comprising a rocker arm having rolling stroke sections arranged in parallel.
Summary of the invention The present invention is realized by adopting the following technical solution: the excavator or loader comprising a rocker arm having rolling stroke sections arranged in parallel comprises a rocker arm, a machine body, a work head, etc.; the rocker arm comprises a front roller, a rear roller, a front roller raceway, a rear roller raceway, a telescopic arm, and a telescopic support arm, etc.; the front roller raceway is disposed on the telescopic arm or the telescopic support arm, or the like; the rear roller raceway is disposed on the telescopic support arm or the telescopic arm or the machine body or the like; the front roller is disposed on the telescopic support arm or the telescopic arm or the like; the rear roller is disposed on the telescopic arm or the telescopic support arm or the like; the front roller raceway and the rear roller raceway are arranged in parallel; the front roller rolls within the front roller raceway; the rear roller rolls within the rear roller raceway; the front roller coordinates with the rear roller to support the telescopic arm to perform rolling-friction extending and retraction on the telescopic support arm by means of rolling friction; the work head is connected with the telescopic arm which drives the work head to extend and retract; and the telescopic support arm is connected with the machine body.
The present invention further comprises the following method for arranging rolling-friction extending and retraction based rolling stroke sections of a rocker arm in parallel, which is specifically as follows.
Method 1:
Step 1: providing a front roller, a rear roller, a front roller raceway, a rear roller raceway, a telescopic arm, a telescopic support arm, etc.; disposing the front roller raceway on the telescopic arm or the telescopic support arm or the like; disposing the rear roller raceway on the telescopic
