Abstract
The invention relates to a propeller strut of an electric tire crane, which comprises a front brace rod, a back pull rod, a line shaft and a connecting rod, wherein the connecting rod is horizontally arranged between the front brace rod and the back pull rod to be fixed to form an entire truss structure by utilizing a plurality of connecting bolts; the front brace rod and the back pull rod are connected on the top of the strut body by utilizing the line shaft; and the lower parts of the front brace rod and the back pull rod are connected with the upper surface of a rotary table by utilizing hinge pins. The propeller strut of an electric tire crane has the advantages that the stiffness of the propeller strut is greatly enhanced by adopting the integral truss structure in the propeller strut; the propeller strut of a crane shakes is avoided swinging left to right in the working process; the subsidiary stress of the front brace rod is eliminated and the application scope is widened; and the front brace rod of the propeller strut simultaneously cancels a middle connecting hinge pin to eliminate the danger that the entire instability of the front brace rod because of abrasion interval enlargement of the connecting hinge pins and holes appears.
Description
Technical field
The present invention relates to the stressed member of electric tyre crane, relate in particular to a kind of propeller strut of electric tire crane.
Background technology
Shears is the main stressed member of electric tyre crane; Electric tyre crane hoisting moment in the market is all smaller.Shears is general to be adopted collapsiblely, and as shown in Figure 2, its front strut is each two independent rod member up and down, connects with bolt of strap plate between the strut on two, also with the bolt of strap plate connection, connects with bearing pin between last lower supporting rod between two lower supporting rods; Back stay is made up of two telescopic arm-ties, the phenomenon of wigwag motion can appear in this structure in hoisting crane work process, the subsidiary load that the Shears front strut produces is bigger, bonded assembly bearing pin and pore volume gap increase easy to wear between the last lower supporting rod of while front strut, cause the whole unstability of front strut probably and cause danger, therefore can only on the electric tyre crane of little tonnage, use.In addition, the DLQ type 40T container power-driven wheel-mounted crane hoisting moment of exploitation reaches 680 tons at present. and rice, former Shears structure has been subjected to certain restriction on Applicable scope.For overcoming the problem of Shears generation wigwag motion in the hoisting crane work process, propeller strut of electric tire crane must adopt new version.
Summary of the invention
At above defective, the purpose of this invention is to provide a kind of support body rigidity and strengthen, adopt whole truss structure, propeller strut of electric tire crane that Applicable scope is wider, with avoid hoisting crane in the course of the work Shears produce the phenomenon of wigwag motion and the whole unstability of front strut.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of propeller strut of electric tire crane, comprise front strut, back stay, celestial axis and pipe link, be horizontally disposed with pipe link between described front strut and the back stay and by some tie bolts truss structure that fixedly forms a whole, described front strut is connected by celestial axis in the support body top with back stay, and front strut is connected with plane on the turntable by bearing pin respectively with the bottom of back stay.
The beneficial effect of propeller strut of electric tire crane of the present invention is: Shears adopts whole truss structure, the rigidity of Shears is greatly increased, hoisting crane Shears wigwag motion phenomenon in the course of the work is completely resolved, and the additional stress of front strut is eliminated, and Applicable scope is wider; Connect bearing pin in the middle of the Shears front strut cancellation simultaneously, the wearing clearance of having eliminated because of connecting bearing pin and hole increases the danger that produces the whole unstability of front strut.
Description of drawings
According to embodiment and accompanying drawing the present invention is described in further detail below.
Fig. 1 is the structural representation of the described propeller strut of electric tire crane of the embodiment of the invention;
The structural representation of the existing propeller strut of electric tire crane of Fig. 2.
Among the figure:
1, front strut; 2, back stay; 3, celestial axis; 4, pipe link; 5, tie bolt; 6, bearing pin; 7, plane on the turntable.
The specific embodiment
Shown in Fig. 1-2, propeller strut of electric tire crane of the present invention, comprise front strut 1, back stay 2, celestial axis 3 and pipe link 4, be horizontally disposed with pipe link 4 between described front strut 1 and the back stay 2 and by some tie bolts 5 truss structure that fixedly forms a whole, described front strut 1 is connected by celestial axis 3 in the Shears top with back stay 2 upper ends, and front strut 1 is connected with plane 7 on the turntable by bearing pin 6 respectively with the bottom of back stay 2; When assembling, earlier front strut 1 is set to a truss structure, back stay 2 also is set to a truss structure, again front strut 1 and back stay 2 usefulness connecting-rod bolts 5 are connected into a whole truss structure, front strut 1 is connected by celestial axis 3 on the Shears top with back stay 2 tops, and the bottom is connected with turntable with bearing pin 6.Compared with prior art, Shears adopts whole truss structure, and the rigidity of Shears is greatly increased, and hoisting crane Shears wigwag motion phenomenon in the course of the work is completely resolved, and the additional stress of front strut 1 is eliminated; Connect bearing pin in the middle of Shears front strut 1 cancellation simultaneously, the wearing clearance of having eliminated because of connecting bearing pin and hole increases the danger that produces front strut 1 whole unstability.
