Abstract
The utility model provides a jacking beam anti-drop device which can ensure that a hanging plate and a step are firmly positioned in a jacking or descending process of a self-elevating tower crane, so that a jacking beam is firmly supported on a tower body support structure to guarantee safety. The jacking beam anti-drop device comprises a jacking beam, a hydraulic oil cylinder support, a standard knot, a step and a hanging plate, wherein the step is welded on the standard knot, the hydraulic oil cylinder support is arranged at the middle part of the jacking beam, the upper part positions at the two side parts of the jacking beam are firmly connected with the lower part of the hanging plate respectively, and the upper part of the hanging plate is hung in a mounting slot of the step on the corresponding side. The jacking beam anti-drop device is characterized in that the hanging plate is divided into an inner-side hanging plate and an outer-side hanging plate, a bolt hole is formed in the inner-side hanging plate, and the bolt hole is positioned below the step position after hanging.
Description
Technical field
The utility model relates to the technical field of structures of tower crane, is specially a kind of jacking cross beam anti-drop device.
Background technology
Tower crane is the conventional crane hoisting equipment of building industry, when tower machine subtracts joint during operation rising tower supernumerary segment or fall tower, on marking time in the both sides that the link plate at jacking cross beam two ends must be hung over to standard knot, utilize jacking cylinder the above part jacking of tower machine undersetting certain altitude, then increase or reduce standard knot.Existing tower crane is in jacking or decline process, its jacking cross beam is hung in the mounting groove of marking time both sides by the link plate of both sides, because the cooperation of link plate and mounting groove is only the spacing of single direction, it makes tower crane in jacking or decline process, there is the risk of link plate from deviating from the groove of marking time, and then the potential safety hazard that causes jacking cross beam to depart from from tower body supporting structure.
Summary of the invention
For the problems referred to above, the utility model provides a kind of jacking cross beam anti-drop device, and it can guarantee to make tower crane in jacking or decline process, link plate and mark time between firm position, make jacking cross beam firm support in tower body supporting structure, guarantee safety.
A kind of jacking cross beam anti-drop device, its technical scheme is such: it comprises jacking cross beam, hydraulic ram bearing, standard knot, mark time, link plate, described marking time is welded in described standard knot, the middle part of described jacking cross beam is provided with hydraulic ram bearing, the upper position of the both sides of described jacking cross beam is fastenedly connected respectively the bottom of described link plate, the top of described link plate mounts in the mounting groove of marking time described in respective side, it is characterized in that: described link plate is divided into inner side link plate, outer side suspending board, on the link plate of described inner side, have pin hole, described in after described pin hole is positioned at and mounts, mark time position under, locking pin is plugged in described pin hole, the horizontal ends of spacing angle steel is welded to connect described inner side link plate, the vertical end of described spacing angle steel has support holes, the outer end of described anticreep latch is supported in described support holes, the middle part of described anticreep latch is provided with vertically to the handle of arranging.
It is further characterized in that: the both sides of described jacking cross beam are boatswain chair, and the both sides on the top of every described boatswain chair are respectively the bottom of inner side link plate, outer side suspending board, and connecting bolt is fastenedly connected after running through respectively described inner side link plate, boatswain chair, outer side suspending board.
Adopt after structure of the present utility model, when tower machine in jacking or decline process, after link plate mounts in the mounting groove of marking time described in respective side, driving handle, inserts in pin hole anticreep latch, until handle is close to the outer wall of inner side link plate, now anticreep latch be positioned at the position of marking time under, and mark time and anticreep latch between only leave a small amount of gap, make link plate and mark time between firm position, make jacking cross beam firm support in tower body supporting structure, guarantee safety; After tower machine completes jacking or declines, manually extract handle, until handle fits in the medial surface of location angle steel, remove anticreep latch for marking time, link plate spacing, simple to operate, safe and reliable.
