Abstract
The utility model relates to an anti-loosening device for a jacking beam of a climbing rack for a self-elevating tower crane. The anti-loosening device comprises a jacking beam (1), a support plate (2), tank-shaped boxes (3), straight pin shafts (4) and handles (5), wherein the tank-shaped boxes are welded below the pin shafts at the two ends of the jacking beam, and the handles are arranged in U-shaped grooves of bottom plates of the tank-shaped boxes; and through holes are arranged on the support plate, and the straight pin shafts are inserted into the through holes. When the anti-loosening device is used, the pin shafts are pushed out or retracted by the handles so as to achieve the anti-loosening purpose. The device is simple in structure, is safe and reliable, and is easy to popularize.
Description
Technical field
The utility model relates to a kind of self-raising tower crane frame jacking crossbeam anti-drop device that climbs that relates to.
Background technology
Before the jacking crossbeam does not design anti-drop device,,, cause the both ends bearing pin of jacking crossbeam from the body of the tower supporting, to be deviate from voluntarily, possibly cause the generation of the accident of falling the tower owing to climb frame and body of the tower some " interference " do not know at normal supernumerary segment, when falling the joint operation.
Summary of the invention
For addressing this problem, our customized design a kind of self-raising tower crane frame jacking crossbeam anti-drop device that climbs.
This anti-drop device comprises jacking crossbeam 1, back plate 2, box box 3, sells axle 4, handle 5 directly to households, and wherein, the bearing pin below, two ends of jacking crossbeam is welded with a box box, and handle is located in the U-lag of box box plate; Back plate is provided with a through hole, sells axle directly to households and inserts in the through hole.
With handle outside release of bearing pin or withdrawal can be reached the anticreep purpose during use.
This apparatus structure is simple, and is safe and reliable, is easy to promote.
Description of drawings
The structural representation of Fig. 1 device,
Fig. 2 A-A cutaway view.
The specific embodiment
Start pumping plant, the two ends bearing pin of jacking crossbeam is positioned in the last circular arc of standard knot back plate, attention jacking crossbeam two ends and back plate gap are even; Turning handle is in horizontality; To sell axle directly to households and outwards release respectively, insert in the hole of standard knot back plate, rotate handle; Handle is snapped in the U-lag of " box box " base plate, and anti-drop device can be used safely.
Handle is outwards pulled out from the U-lag of " box box " base plate, and turning handle will be sold axle directly to households and inwardly advance respectively in horizontality, rotate handle, handle snapped in another U-lag of " box box " base plate, promptly accomplish withdrawing from of anti-drop device.
