Abstract

A real-time monitoring device used for monitoring the operating duty of the tower crane so as to lower the tower crane-related accident; this model is characterized in that the information acquisition module is connected with the amplitude information sensor, the weight information sensor and the altitude information sensor; also, the information acquisition module is connected to the main control module which is jointed with the storage, the display unit and the circuit control element of the tower crane. The circuit control element is connected to the input end of the tower crane circuit. The amplitude information collected from the information acquisition module can be compared with the pre-set value inside the storage via the main control module so as to arrive at the maximum hoisting capacity of the cart at the current position. When the maximum hoisting capacity is reached or exceeded, the power supply for the working direction of the cart and the lifting direction of the hook can be cut off. Thus, the cart can only move back and the hook can only move down In this case, the safety operation of the tower crane can be guaranteed. Also, current working parameter of the tower crane can be displayed simultaneously on the display unit.

Description

Tower machine working state real-time monitoring device

Affiliated technical field

The utility model relates to a kind of safety device of tower machine equipment, especially a kind ofly can effectively prevent the real time monitoring apparatus of tower machine safety misadventure.

Background technology

People all need to use a large amount of tower machines when building high building, to transport required steel, cement, materials such as brick, and known widely used tower machine load limitation device is the mechanical type limiting device at present, when reaching a threshold value, goods can cut off the dynamo-electric source of tower, but prolongation along with period of service, it is very unstable that the mechanical type limiting device can become, can not accurately play the limit for tonnage function, and the cargo weight of tower machine operation personnel to being lifted, height and dolly present position all can't obtain data message exactly, can only rule of thumb judge, so very easily make tower machine overload operation, thereby the collapse serious accident of personal casualty of tower machine appears, because of can't accurately obtaining the correlation parameter of tower machine work at present state, tower machine operation personnel can not be known the residing position of suspension hook exactly when obstacle is arranged, psychology to tower machine operation personnel also causes very big burden like this, also comes certain hidden danger for the safety of tower machine.

Summary of the invention

In order to solve the problem that safety problem that existing tower machine exists and tower machine operation personnel can not understand current tower machine mode of operation at any time, the utility model product provides a kind of tower machine working state real-time monitoring device, this device can not only play the limit for tonnage effect, and can show all working parameter of current tower machine in real time, so that tower machine operation personnel understand the working condition of current tower machine in real time.

The technical scheme that its technical matters that solves the utility model adopts is: on tower machine vehicle motor the amplitude information collector is housed, the elevation information collector is housed on the suspension hook motor, at the proving ring place weight information collector is housed, and be connected with information acquisition module respectively, the other end of information acquisition module is connected with the master control module, the master control module more respectively with memory device, telltale, tower machine circuit control unit connects, the master control module compares the amplitude that prestores in amplitude information that information acquisition module collected and the memory device, thereby calculate the Maximum Loading Capacity of current dolly present position, again the actual measurement weight (AMW) that this load carrying ability and current suspension hook hung is compared, if institute's lift heavy amount reach default Maximum Loading Capacity 90% send yellow early warning signal, this moment, the tower machine can normally move, when institute's lift heavy amount reach default Maximum Loading Capacity 100% the time then send the red early warning signal, this moment, the tower machine still can normally move, but when institute's lift heavy amount reach default Maximum Loading Capacity 105% the time then the power supply of tower machine dolly working direction and suspension hook ascent direction is cut off the power supply, make dolly to shrink back and suspension hook can only be toward descending, thereby guarantee the safe operation of tower machine, avoid accident to take place.

The beneficial effects of the utility model are: can calculate the current location Maximum Loading Capacity according to the dolly present position in real time, when reaching default Maximum Loading Capacity 90%, can send yellow early warning signal, can send the red early warning signal at 100% o'clock that reaches default Maximum Loading Capacity, can cut off the power supply to the dynamo-electric source of tower at 105% o'clock that reaches default maximum gross value, and can be in real time the working parameter of current tower machine be shown on telltale, tower machine operation personnel can very clearly know the relevant important number that the tower machine is current, help the safe operation of tower machine, alleviate tower machine operation personnel's psychological burden, can effectively avoid safety misadventure to take place, this product structure is simple, install, it is easier to operate, the tower machine and the later maintenance expense that are suitable for various models are low, are beneficial to popularization.
