Description
Technical Field
The utility model belongs to the technical field of hoisting machinery safety protection test device technique and specifically relates to a bow type board moment limiter analogue test device.
Background
The tower crane is generally composed of a tower body, a tower arm, a tower cap and the like, and the load bearing capacity of the metal of the tower crane is directly related to the product of lifting capacity and amplitude, namely moment. The bow-shaped plate moment limiter is equipment for detecting and limiting the moment of the tower crane. The moment limiter is structurally characterized in that two arc-shaped plates with radian are arranged, two ends of each arc-shaped plate are welded on the ear plates, the ear plates are welded on a propeller strut of a tower cap, when a tower crane lifts a load, the propeller strut is pulled, the arc-shaped plates deform along with the tension, a contact and a contact are arranged in the middle of each arc-shaped plate, the two arc-shaped plates are pulled to reduce the radian, the contact and the contact are contacted, a starting alarm device is arranged, when the load continues to increase, the contact which stops working is contacted with the contact, a starting system is powered off, the load can not lift or move in the direction with increased amplitude, and the function of limiting the.
The tower body, the tower arm and the propeller strut of the tower crane are all truss structures consisting of rod pieces, the lifting and amplitude changing mechanisms are steel wire rope structures, and the deformation, the mechanical efficiency and the structural size are not easy to calculate, so that the stress of the arch-shaped plate is difficult to calculate according to the tower crane, the rated torque is generally set by controlling the deformation of the arch-shaped plate, and then the relationship between the stress and the deformation of the arch-shaped plate is also very difficult to calculate. Through a test device, the relation between the stress and the deformation of the bow plate moment limiter is directly measured, and the test device is visual and important.
At present, bow type board moment limiter is hardly tested, basically, direct mount lifts by crane certain weight on tower machine's propeller strut, moves to the scope of settlement, make moment reach rated torque, the length of the first contact of adjustment at this moment, make contact and contact, reach the settlement of early warning point, then continue to increase weight, perhaps weight is unchangeable, increase scope, make moment reach the stop point of settlement, the length of adjustment second contact this moment, make contact and contact, reach the settlement of stop point.
However, such tests have the following disadvantages:
(1) the product precision can not be guaranteed. The product leaves factory and is not calibrated, the product is installed on a tower crane, and the contact head is adjusted according to the lifting capacity and the amplitude so as to determine the contact position for early warning and stopping. When in site calibration, the suspended load weight, the tower arm length and the tower arm angle are not easy to be measured accurately, so the precision of the calibrated action point can not be ensured, and the precision of the torque limiter can not be ensured.
(2) The cost of calibration on site one by one is high, and even the calibration cannot be carried out. After the bow plate moment limiter is installed on the tower crane, debugging personnel need to arrive at the site to lift a load with a certain weight, adjust the running trolley to a set position to enable the product of the weight and the amplitude of the load to reach an early warning point, and adjust a contact on the bow plate moment limiter to enable the contact to be in contact with the contact; then the load or the amplitude is increased, so that the achievement of the load weight and the amplitude reaches a stop point, and a debugging person adjusts the contact on the bow-shaped plate moment limiter, so that the contact is contacted with the contact. Each crane needs to be debugged, the maximum lifting capacity and the maximum amplitude need to be lifted, the field lifting load is not easy to obtain, the load with accurate weight is not easy to obtain, and the amplitude is not suitable to be adjusted in place, so the field debugging is time-consuming, labor-consuming and expensive.
(3) And the danger of field debugging is large. When the maximum torque is required to be achieved during field debugging and the hoisting load enables the tower crane to achieve the maximum bearing capacity, debugging personnel must be located at the tower cap at the highest position of the tower crane, wherein the debugging personnel is one of the most dangerous places.
(4) The consistency of the product quality cannot be ensured. Each product is not debugged when leaving the factory, the use requirement is met through field calibration, and a batch of products leaving the factory has no consistency.
(5) The product research and development has no quality guarantee. The product is not subjected to design calculation, calibration before delivery is not carried out, and on-site calibration is carried out regardless of the quality, so that the product has no quality.
