Abstract
The utility model relates to a telescoping mechanism of a slipform paver main frame. The telescoping mechanism comprises a main frame body, and a left telescoping structure and a right telescoping structure which are arranged on the main frame body. The left telescoping structure comprises a left telescoping rod and a left driver, wherein the right end of the left telescoping rod is inserted into an insertion hole of the main frame body; the left driver drives the left telescoping rod to stretch; and an axial hole to the left is formed in the right end face of the left telescoping rod. The right telescoping structure comprises a right telescoping rod and a right driver, wherein the left end of the right telescoping rod is inserted into the insertion hole of the main frame body; the right driver drives the right telescoping rod to stretch; the external diameter of the right telescoping rod is less than the diameter of the axial hole of the left telescoping rod; axes of the right and left telescoping rods are positioned on a same straight line; and the weight of the right telescoping rod is equal to that of the left telescoping rod. The telescoping mechanism can maintain a whole machine balanced, so that the weight of the machine can be uniformly distributed by a running system, and the weight of the machine and the running system can be matched with each other in a most effective manner.
Description
Technical field
The utility model belongs to the paver equipment technical field, is specifically related to a kind of telescoping mechanism of sliding form spreading machine mainframe.
Background technology
In sliding form spreading machine work, usually need to regulate according to the requirement of paving width the frame width of slip form paver.External sliding form spreading machine product only has Unidirectional telescopic rack construction, and its stretching structure can only monolaterally stretch to realize the adjusting of mainframe width; This kind one-way expansion structure in paving process, on one side easily cause machine to topple over, is unfavorable for the machine quality to the uniform distribution of running gear, is difficult for realizing the most effectively mating between machine quality and walking driving force.
Summary of the invention
For above-mentioned technical problem, the utility model provides a kind of telescoping mechanism of sliding form spreading machine mainframe, and it can in paving process, guarantee the balance of machine integral body, be convenient to machine weight and distributed uniformly by running gear, realize the most effectively mating between machine weight and running gear.
Realize that the technical solution of the utility model is as follows:
the telescoping mechanism of sliding form spreading machine mainframe, comprise main frame body, and be arranged on left stretching structure on main frame body, right stretching structure, left stretching structure comprises left expansion link, the right-hand member of left expansion link is inserted in the jack of main frame body, and drive the flexible left driver of left expansion link, described left expansion link right side is provided with axial hole left, right stretching structure comprises right expansion link, the left end of right expansion link is inserted in the jack of above-mentioned main frame body, and drive the flexible right driver of right expansion link, the external diameter of described right expansion link is less than the diameter of left expansion link axial hole, and the axis of right expansion link and the axis of left expansion link are on same straight line, being equal in weight of described right expansion link and left expansion link.
Be provided with pilot bushing in the right-hand member jack of described main frame body, right expansion link passes pilot bushing.The effect of pilot bushing is to guarantee the axis of the axis of right expansion link and left expansion link on the same level straight line, thereby in telescopic process, right expansion link can insert in the axial hole of left expansion link smoothly.
Described left driver, right driver are for driving oil cylinder or cylinder.The stroke of left driver, right driver is less than the stroke of left expansion link, right expansion link, thereby guarantees that left expansion link, right expansion link can not skid off in the jack of main frame body.
Adopted such scheme, in the sliding form spreading machine paving process, in the time of need to regulating slip form paver frame width, as long as by driving left driver, right driver, because left driver, right driver are driven in synchronism, it can make the flexible of left expansion link, right expansion link while, thereby makes frame reach same width, while is because right expansion link and left expansion link is equal in weight, one side therefore guarantee that main frame body is to toppling over.The utility model can guarantee the balance of machine integral body, is convenient to machine weight and is distributed uniformly by running gear, realizes the most effectively mating between machine weight and running gear.
