Abstract

A controllable mechanism type low loader comprises a travelling device, a frame, a boom, a boom lifting support chain, a bucket turning support chain and a bucket. The frame is installed on the travelling device. The boom is hinged to the frame, and the other end of the boom is hinged to the bucket. The boom lifting support chain is used for controlling the boom to ascend or descend. The bucket turning support chain is used for controlling the bucket to turn. The boom lifting support chain and the bucket turning support chain are driven by servo motors mounted on the frame respectively. The boom lifting support chain and the bucket turning support chain coordinate with each other to complete loading for the loader. The controllable mechanism type low loader avoids the shortages that hydraulic loaders are high in hydraulic elements production precision, hydraulic oil is severely impacted by temperature, a hydraulic system is easy to fail, failure is less easily checked and eliminated, and the like. In addition, compared with the other controllable mechanism type loaders, the controllable mechanism type low loader is simple in structure, low in dead weight and low in production cost and quite suitable for being manufactured into small-sized low loaders.

Description

A kind of controllable mechanism formula low loader
Technical field
The present invention relates to engineering machinery field, particularly a kind of controllable mechanism formula low loader.
Background technology
Loader is a kind of cubic metre of earth and stone construction machinery that is widely used in construction projects such as highway, railway, building, water power, and it is mainly used in loose unpacked materials such as shovel dress soil, sandstone, also can dig operation to the slight shovel of works such as ore, pan soil.Change that kind of different auxiliary working apparatus also can be bulldozed, the handling operation of lifting and unclassified stores.In recent years, along with China's rapid economy development, the utilization rate of small engineering machinery machine in urban construction and modernized agricultural production was more and more; At aspects such as municipal engineering, stream, river course desilting engineerings, small sized loader has many-sided advantages such as transportation, energy consumption, flexibility, adaptation, is highly suitable for the narrow and small construction plant operation in space; Along with the quickening of China's Development of China's Urbanization, small sized loader is good in China's development prospect, and present most loader adopts hydraulic system; Though use generally, this type loader also exists many deficiencies and shortcoming, at first; Hydraulic pressure components and parts manufacturing cost is high, and hydraulic system is high to maintenance requirement in the future, is unfavorable for maintenance; Secondly; Hydraulic oil receives the surrounding environment factor affecting easily, low cold and the high temperature area is particularly evident, also can be attended by the pollution to environment such as noise simultaneously.
Raising along with development of NC technology and mechanical industry level; The numerical controlization of engineering machinery is the new development trend of engineering machinery field, and the combining of Numeric Control Technology and engineering machinery can make the engineering machinery performance get a qualitative improvement, because of it has simple in structure; Control easily; Maintaining is simple, and therefore plurality of advantages such as low cost of manufacture have wide development space.With the novel controllable mechanical of driven by servomotor, be the main forms of engineering machinery field Numeric Control Technology, this type engineering goods performance and total quality are increased dramatically; And simple in structure, control easily, maintaining is simple; Therefore low cost of manufacture has wide development space.But more existing controllable mechanism formula loaders, linkage is complicated, and mechanism partly conducts oneself with dignity bigger, has influenced the overall performance of loader.
Summary of the invention
The problem that the objective of the invention is to the prior art existence provides a kind of controllable mechanism formula low loader; Satisfy under traditional loader job requirements prerequisite in assurance; Avoid the hydraulic loader Hydraulic Elements accuracy of manufacture require high, the hydraulic oil temperature influence is serious, hydraulic system breaks down shortcomings such as being difficult for inspection and eliminating; And compare with other controllable mechanism formula loader, should have simple in structure, advantage such as the shaft portion deadweight is little.
The present invention achieves the above object through technical scheme once:
A kind of controllable mechanism formula low loader is made up of running gear, frame, big arm, big arm lifting side chain, scraper bowl upset side chain, scraper bowl.
Said big arm is connected with frame through first fraising, and the other end is connected with scraper bowl through second fraising.
Said big arm lifting side chain is made up of first driving lever, first connecting rod, and first driving lever, one end is connected with frame through the 3rd fraising, and the other end is connected with first connecting rod through the 4th fraising, and the first connecting rod other end is connected with big arm through the 5th fraising.Said first driving lever, is driven big arm completion act and falls operation through first connecting rod by rack-mounted first driven by servomotor.
Said scraper bowl upset side chain is made up of second driving lever, second connecting rod, and second driving lever, one end is connected on the frame through the 6th fraising, and the other end is connected with second connecting rod through the 7th fraising, and the second connecting rod other end is connected with scraper bowl through the 8th fraising.Said second driving lever, is driven scraper bowl and accomplishes the upset operation through second connecting rod by rack-mounted second driven by servomotor.
Said frame is installed on the running gear; The big arm lifting side chain of said this controllable mechanism formula low loader, scraper bowl upset side chain are by rack-mounted driven by servomotor; Accomplishing big arm and lift and fall and scraper bowl upset operation, can be that servomotor provides electric power through internal combustion engine, also can adopt hybrid power to drive; Under the cooperation of running gear, accomplish loading operation jointly.
The outstanding advantage of the present invention is:
1, satisfying under the prerequisite of loading operation, adopted easy linkage; Not only practice thrift cost, and significantly reduced the weight of loader mechanism shaft portion, improved the reliability of shaft portion; Reduce motion of mechanism inertia, had kinematics and dynamic performance preferably.
2, this controllable mechanism formula low loader utilizes linkage to replace the conventional hydraulic transmission, avoided the hydraulic loader Hydraulic Elements accuracy of manufacture require high, the hydraulic oil temperature influence is serious, hydraulic system breaks down shortcomings such as being difficult for inspection and eliminating; Because each driving lever by driven by servomotor, not only is easy to programming Control, and is practical; And the adjustable operational scope is wide, and operating efficiency is high, has better flexibility simultaneously; Reaction speed is fast, can be widely used in low loader.
3, because this controllable mechanism formula low loader adopts the power set of servo motor driving system as hydraulic loader; The utilization computer technology is controlled the operation process of loader; Fundamentally promoted the performance of loader, made this loader have the vast market development potentiality.
