Abstract
An A-Bracket for an electric tire crane includes a front stay bar, a back pull bar, a celestial axis and connecting bars; connecting bars are horizontally disposed between the front stay bar and the back pull bar; the front stay bar and the back pull bar are fixed by a plurality of connecting bolts to form an integral truss structure; the top portions of the front stay bar and the back pull bar are connected by the celestial axis; and the lower portions of the front stay bar and the back pull bar are respectively connected with an upper plane of a rotary table through pin shafts. The utility model has the beneficial effect that the A-Bracket employs an integral truss structure so as to greatly enhance the rigidity of the A-Bracket; shaking phenomenon in the horizontal direction of the A-Bracket is thoroughly removed in the operation process of the crane, and an additional stress of the front stay bar is eliminated, therefore, the A-Bracket has a wide application range; and meanwhile, the connecting pin shaft for the front stay bar of the A-Bracket is removed so as to eliminate the danger of integral destabilization of the front stay bar owing to increased wear clearance between the connecting pin shaft and the hole.
Description
Technical field
The utility model relates to the stressed member of electric tyre crane, relates 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.
The utility model content
At above defective, the purpose of this utility model provides a kind of support body rigidity and strengthens, adopts 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 utility model 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 described in the utility model 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 utility model is described in further detail below.
Fig. 1 is the structural representation of the described propeller strut of electric tire crane of the utility model embodiment;
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 described in the utility model, 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.
