Abstract
The utility model relates to a tool fixture for making a lifting beam of a tower crane, and the tool fixture is characterized in that the tool fixture comprises a chuck plate, a support block, a slide block, a screw rod, pin shafts, a screw mandrel and a stop block; a slide plate is fixed on the tool of the lifting beam; the support block, the screw rod and the slide plate are connected through two pin shafts; then the chuck plate is connected with the slide plate through the pin shafts; and finally, the stop block is arranged in a groove of the chuck plate, and the screw mandrel penetrates through the stop block to be connected with the screw rod. The tool fixture for the lifting beam has the advantages that the fixture is mounted on the tool of the lifting beam, of which the size is adjusted through the screw mandrel, so as to be suitable for the assembly of different types of lifting beams; therefore, not only is the tolerance of a lower chord of the lifting beam ensured, but also the material and the space are saved, and the manufacturing cost is reduced.
Description
Affiliated technical field
The utility model is the frock clamp that derrick crane is made crane arm, can be accurately when the assembly unit crane arm fixing crane arm lower boom.
Background technology
It all is some simple positioning tools that at present domestic derrick crane is made crane arm, directly on frock, weld some location-plates, so not only can not guarantee the tolerance between the crane arm lower boom, and the tool locating of different tower machine models is different, all can there be the tower machine of multiple model in each company, thus the workshop only crane arm several frocks are just arranged, caused the waste of material, also take a large amount of spaces, increased manufacturing cost.
Summary of the invention
In order to overcome above-mentioned defective, the utility model provides a kind of derrick crane to make the frock clamp of crane arm.
The technical scheme that its technical problem that solves the utility model adopts is:
Derrick crane is made the frock clamp of crane arm, and it comprises clamp, bracer, slide block, screw rod, bearing pin, screw mandrel, block; Slide plate is fixed on the crane arm frock, with 2 bearing pins bracer, screw rod is connected with slide plate again, then clamp is connected with slide plate with bearing pin, at last block is placed in the groove of clamp, screw mandrel passes block and is connected with screw rod.
The utility model has designed the crane arm frock clamp, and these anchor clamps are installed on the crane arm frock, utilizes screw mandrel alignment jig size, just go for the crane arm assembly unit of different model, so both guarantee the tolerance of crane arm lower boom, also saved material and space, reduced manufacturing cost.
Description of drawings
The installation diagram of Fig. 1 crane arm frock clamp.
Be denoted as among the figure: 1, clamp 2, bracer 3, slide block 4, screw rod 5, bearing pin 6, screw mandrel 7, block
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing 1.
Derrick crane is made the frock clamp of crane arm, it is that slide plate 3 is fixed on the crane arm frock, with 2 bearing pins 5 bracer 2, screw rod 4 are connected with slide plate 3 again, then clamp 1 usefulness bearing pin 5 is connected with slide plate 3, at last block 7 is placed in the groove of clamp 1, screw mandrel 6 passes block 7 and is connected with screw rod 4.
Operation principle is, after installing by last figure mode, the crane arm lower boom is put into the a-quadrant, regulates the position of bracers 2 with screw mandrel 6, changes the size of a-quadrant, and lower boom is fixed on the frock, so just can guarantee the tolerance between the crane arm lower boom.
At last, should be pointed out that above embodiment only is the more representational example of the utility model.Obviously, the technical solution of the utility model is not limited to the foregoing description, and many distortion can also be arranged.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model all should be thought protection domain of the present utility model.
