Description

Tower crane jacking climbing position monitoring device

Technical Field

The utility model relates to the technical field of construction site equipment, in particular to a tower crane jacking climbing position monitoring device.

Background

The tower crane is the most common hoisting equipment on the construction site, also called tower crane, and is used for hoisting construction raw materials such as reinforcing steel bars, wood ridges, concrete, steel pipes and the like for construction by the extension (height) of one section and one section (called standard section for short). The tower crane is an indispensable device on a construction site. The tower crane (tower crane) tip has the function of bearing the upper load transmitted by the boom guy rope and the balance arm guy rope, and directly transmits the upper load to the tower body structure through the rotary tower, the rotary table, the bearing seat and other structural components. The self-elevating tower top is provided with a truncated cone column type, a forward-inclined or backward-inclined truncated cone column type, a herringbone frame type and an inclined support frame type. The upper slewing tower crane is required to be provided with a balance weight, and the function of the upper slewing tower crane is to support the balance weight so as to form a balance moment which is required by design and has the action direction opposite to the lifting moment direction. In addition to the counterweight, a hoisting mechanism is often provided at the tail. The hoisting mechanism and the balance weight are arranged at the tail end of the balance arm together, so that partial balance weight function can be achieved, and the distance between the rope reel and the tower tip guide wheel is increased, so that the steel wire rope can be conveniently wound and rope disorder is avoided. The dosage of the balance weight is in inverse proportion to the length of the balance arm, and the length of the balance arm is in proportion to the length of the crane boom. The balance weight is considerable, the light tower crane generally needs 3-4 t at least, and the heavy tower crane needs 30t nearly.

All can use hydraulic lifting rod to carry out jacking operation when present tower crane rises installation standard festival, tradition all be directly with jacking crossbeam scarf joint into both sides between the power piece can, but the tower crane is when jacking operation, often can present certain slope form, if the slope is too big, can lead to the atress size inhomogeneous in jacking in-process both sides, if the duration overlength, perhaps jacking crossbeam or tower crane crossbeam have reasons such as cracks, then cause potential dangerous operation or jacking accident even easily, so just need the atress condition of a monitoring jacking crossbeam both sides in jacking process.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a tower crane jacking and climbing position monitoring device, which monitors the pressure at two ends in real time during jacking operation by arranging a pressure sensor in an embedded groove on a jacking force block, and a nearby worker observes the pressure data at two ends in real time through a display screen, and gives an alarm through an early warning loudspeaker when the pressure data exceeds a set threshold value, and the worker emergently controls a hydraulic rod through an emergency button in real time.
