Abstract
The utility model discloses an adjustable auxiliary arm pull plate of a crane. The adjustable auxiliary arm pull plate comprises a single pull plate and a dual pull plate which are connected with each other through pin shafts and shaft holes, wherein a plurality of shaft holes are respectively formed in the single pull plate and the dual pull plate. A plurality of shaft holes are respectively formed in the single pull plate and the dual pull plate, and the single pull plate and the dual pull plate are connected with each other through different shaft holes, so that various lengths can be adjusted and converted; when the crane works under different arm support lengths and different working conditions, only the pull plate is adjusted to a required length instead of a condition that the number of pull plates is increased or decreased or the pull plates with different lengths are converted to a required working condition; the convenience in operation is improved; and time and labor are saved; and the labor intensity and the cost are reduced. Moreover, the adjustment range and the adjustment precision are improved.
Description
One, technical field
The utility model belongs to hoisting crane part technical field, is specifically related to a kind of hoisting crane and can regulates the auxiliary arm-tie.
Two, background technology
The auxiliary of existing hoisting crane has multiple operating angle and multiple brachium composite condition mostly, when requiring in different operating mode situations, to work, often to increase and decrease the quantity of arm-tie or change the different length arm-tie and be transformed into required operating mode, waste time and energy, and also increased cost payout to a certain extent.
Three, summary of the invention
The purpose of this utility model provides a kind of simple in structure, reasonable in design, can effectively overcome
The hoisting crane of many deficiencies of existing auxiliary arm-tie can be regulated the auxiliary arm-tie.
For achieving the above object, the technical solution adopted in the utility model is: this arm-tie comprises single arm-tie and the two arm-tie that links together by bearing pin and axis hole, is characterized in: be respectively equipped with a plurality of axis holes at single arm-tie and two arm-tie.
Owing to being respectively equipped with a plurality of axis holes at single arm-tie and two arm-tie, single arm-tie connects by different axis holes from two arm-ties, realize different lengths adjusting conversion, when hoisting crane is worked in different jib length and different operating mode situations, need not to increase and decrease the quantity of arm-tie or change the different length arm-tie and be transformed into required operating mode, only need that this arm-tie is adjusted to Len req and get final product, improved the convenience that operates, time saving and energy saving, also reduced labour intensity and cost payout.Simultaneously, setting range and degree of regulation have also been improved.
Four, description of drawings
Fig. 1 is structural representation of the present utility model;
The lateral plan of Fig. 2 Fig. 1;
Fig. 3 is working state figure of the present utility model.
Five, the specific embodiment
As shown in Figure 1 and Figure 2, the utility model comprises single arm-tie 8 and two arm-tie 9, and wherein two arm-ties 9 are double-decker, and single arm-tie 8 is clipped in the middle; The outer end of single arm-tie 8 and two arm-ties 9 is respectively equipped with for the pin shaft hole 10 that connects.On single arm-tie 8, be provided with successively axis hole 1, axis hole 2, axis hole 3 along line of centers; Line of centers is provided with axis hole 4, axis hole 5, axis hole 6 successively on two arm-ties 9.Among the figure, single arm-tie 8 and two arm-tie 9 link together by hole 3, hole 4 and bearing pin 7.
As shown in Figure 3, during use, with being connected with unadjustable single arm-tie by pin shaft hole 10 and bearing pin on two arm-ties 9, be connected with strut bar 11 upper ends, single arm-tie 8 connects with many that are connected with auxiliary 12 front ends unadjustable arm-ties 13 by pin shaft hole 10 and bearing pin again.
The utility model can be realized six kinds of length adjustment conversion, concrete regulative mode following (push away the SC70C crawler crane take the mountain and be example): when being in 18 meters arm-tie states of 10 degree, axis hole 1 is connected with axis hole 6; When being in 18 meters arm-tie states of 30 degree, axis hole 1 is connected with axis hole 4; When being in 12 meters arm-tie states of 10 degree, axis hole 2 is connected with axis hole 6; When being in 12 meters arm-tie states of 30 degree, axis hole 3 is connected with axis hole 5; When being in 6 meters arm-tie states of 10 degree, axis hole 1 is connected with axis hole 4; When being in 6 meters arm-tie states of 30 degree, axis hole 3 is connected with axis hole 4.
