The utility model discloses an use a compensating beam and a pull rod and constitute a balanced structure to the weight for balanced rod structure requires to have gone up greatly reduced at the machining precision, install more convenient and fast, and the structure is simpler, and is more reasonable, pass do all can clearer and more definite, two compensating beams of the two rod structure of width ratio of compensating beam are little simultaneously, and save material need not to keep the installation of high axiality to require just can install more.
Description
Technical field
The utility model relates to the field of components of single arm support tooth bar stationary crane balanced system, particularly relates to a kind of simplex pull rod balanced system of single arm support stationary crane.
Background technology
At present, in Crane Industry, the particularly balanced system of single arm support tooth bar luffing stationary crane, extensive employing activity counterweight makes the synthesis center of gravity of boom system remain on close on horizontal track, this structure is lever-type movement counterbalancing system, it equals the design of this groundwork of counterweight dead-load moment according to acting on as far as possible to the boom system dead-load moment on jib hinge, because counterweight is separated with jib, adopt lever duplex pull rod to connect, form non-parallel quadrangle four-bar mechanism.Thus can make to be enlarged markedly the pivot angle of weighing arm under the still constant condition of jib pendulum angle, thus increase the adjustable height of counterweight, reduce the quality of counterweight, and the effect of counterweight to crane stability can be given full play to; But the balanced system of duplex pull rod form, is installing because two pull bars must keep high-axiality, accuracy requirement, processing difficulties, difficulty is being installed.
Therefore, prior art has yet to be improved and developed.
Utility model content
The purpose of this utility model is the simplex pull rod balanced system providing a kind of single arm support stationary crane, the balanced system being intended to solve existing single arm support tooth bar luffing stationary crane uses double pull rod structure processing difficulties, high-precision manufacture requirements, must high-axiality be kept, and the technical matters of difficulty is installed.
The technical solution of the utility model is as follows: a kind of simplex pull rod balanced system of single arm support stationary crane, wherein, comprises a weight, an equalizing bar and a pull bar; The end end of described equalizing bar wherein one end is provided with weight, and the other end is connected with pull bar; One end of described pull bar is linked together by connection round pin and equalizing bar, and the other end is used for connecting with crane arm; The width of described equalizing bar is 90% of two equalizing bar width summations in double pull rod structure.
The simplex pull rod balanced system of described single arm support stationary crane, wherein, one end that described equalizing bar is connected with pull bar is provided with engaging lug, connection round pin is passed the engaging lug of pull bar and equalizing bar, just pull bar and equalizing bar can be coupled together.
The simplex pull rod balanced system of described single arm support stationary crane, wherein, the axle center of described engaging lug is with parallel with bottom equalizing bar respectively to the axle center of weight.
The simplex pull rod balanced system of described single arm support stationary crane, wherein, the bottom of described equalizing bar distance to weight one end far away is provided with pin-and-hole, equalizing bar can be arranged on the column top of hoisting crane by this pin-and-hole.
The simplex pull rod balanced system of described single arm support stationary crane, wherein, is describedly above provided with counterweight door to weight, can be realized adjusting and uses different crane arms by counterweight door toward increasing or reduce weight to weight inside.
The simplex pull rod balanced system of described single arm support stationary crane, wherein, described equalizing bar is near being provided with " U " shape through hole to one end of weight.
The beneficial effects of the utility model: the utility model is by use equalizing bar and a pull bar and form a balanced structure to weight, balancing pull rod structure is greatly reduced on requirement on machining accuracy, more convenient and quicker is installed, and structure is simpler, more reasonable, power transmission is clearer and more definite; The width of equalizing bar is less than two equalizing bars of double pull rod structure simultaneously, more saving material, just can install without the need to keeping the installation requirement of high-axiality.
