Tower crane structure with weight detection

Abstract

The invention relates to the technical field of engineering hoisting equipment and discloses a tower crane structure with weight detection. The tower crane structure comprises a base and a tower body vertically fixed on the base, wherein a suspension arm is arranged at the top of the tower body; a weight base block and a winch are arranged at one end of the suspension arm; the other end of the suspension arm is provided with a pulley; a steel rope on the winch winds around the pulley to be connected with the suspension arm; a hook is arranged under the steel rope; a rotary table is arranged in the middle of the suspension arm and is rotationally connected with the top of the tower body; the pulley is provided with a connection shaft; the bottom of the hook is provided with a connection plate; a supporting ring is arranged at the outer end of the connection plate; a cover plate is arranged at the outer end of the supporting ring; a central hole is formed in the center of the cover plate; the outer end of the connection shaft is provided with an anti-releasing baffle; a pressure sensor is arranged between the anti-releasing baffle and the inner end of the cover plate; and the outer end of the cover plate is provided with an alarm lamp connected with the pressure sensor. The tower crane structure can be used for detecting the weight of objects in real time so that whether the tension of an object on the steel rope is in a steel rope load range or not is judged and the utilization is relatively safe.

Description

technical field [0001] The invention relates to the technical field of engineering lifting equipment, in particular to a tower crane structure with weight detection. Background technique [0002] Tower crane is the most commonly used lifting equipment on construction sites, also known as tower cranes. It is used to lift construction materials such as steel bars, wood corrugated, concrete, and steel pipes. Tower cranes are an indispensable equipment on construction sites. The function of the tower suspension tip is to bear the upper load transmitted from the jib stay rope and the balance jib stay rope, and transmit it to the tower body structure directly through the turntable through the structural components such as the slewing tower, turntable, and seat. The top of the self-elevating tower has Truncated cone column, forward or backward inclined truncated cone column, herringbone frame and diagonal brace. A common tower crane generally consists of a base, a tower body, a bo...

Problems solved by technology

In the actual operation process, when the hook is connected to the heavy object, the tension of the steel cable of the hoist will change at the moment the heavy object is hoisted and the heavy object is in the air, but the tensile performance of the steel cable is constant. Therefore, Even if the gravity of some heavy objects is within the tensile range of the cable, the gravity of the heavy object may exceed the rated load of the cable at the moment of lifting or under the influence of wind in the air, and there are potential safety hazards in the overload state of the cable.
