Abstract
The invention relates to a dynamic balance building tower crane which is a lifting appliance in the field of building machinery, and in particular to a dynamic balance building tower crane with a balance weight dynamically moving with lifting weight. The dynamic balance building tower crane comprises a weight, a tower frame, a balance weight, a pivot point, a lifting motor and a cable rope, wherein the electric movable balance weight comprises a controller, a balance weight motor, a movable rail, a weight pulley wheel and a pressure sensor; the pressure sensor is arranged on a lifting point of the weight, and connected with the controller; and the controller is connected with the balance weight motor, the balance weight motor drives the weight pulley wheel to move on the movable rail. The dynamic balance building tower crane solves the problem of lifting arm imbalance of the tower crane in China and abroad, realizes the relative balance of the lifting arm by the movement of the balance weight, automatically moves the balance weight back and forth, reduces the safe accidents of building crane inclination, and decreases the life damage on building workers by the crane. The weight of the lifting arm can be accurately calculated by using the controller of the balance weight.
Description
Technical field:
The dynamical equilibrium building tower crane is a kind of vehicle for construction field weight-lifting equipment, and particularly counterweight is with the dynamically mobile building dynamical equilibrium lifting tower crane of hoisting weight.
Background technology:
Domestic construction tower crane ballast all is movable both at home and abroad at present, move forward and backward the material that will lift by crane and winch to the desired position, consider that ballast can make the arm overbalance at the reversing sense of arm fixing counterweight is set, the counterweight that rough estimation is then in addition suitable, a limit has been done in maximum lifting (ballast) to each distance of arm, adjusting is provided with limiting device, the weight that operating personal lifts by crane according to the requirement decision of limiting device when operation, whole arm just is in non-equilibrium state when ballast moves around.Also have indivedual site operation personnel in order to lift by crane more thing, privately limiting device is regulated artificial increase potential safety hazard.Abroad do not regulated privately for the tower crane limiting device, the real-time monitor of tower crane (being commonly called as black box) has been installed, but whole arm just is not in this problem of non-equilibrium state when the most fundamentally solving ballast and move around, and the safety misadventure that causes because of tower crane arm overbalance takes place both at home and abroad again and again.
Summary of the invention:
Dynamical equilibrium building tower crane goal of the invention of the present invention is: manufacture and design a kind of diverse with prior art, the relative equilibrium that no matter all can both keep arm at the tower crane ballast under what the situation, at utmost reduce building tower crane inclination safety misadventure to the greatest extent, reduce the life injury of tower crane the build labourer.
Dynamical equilibrium building tower crane of the present invention is achieved in that and contains ballast, pylon, counterweight, fulcrum, lifting motor and steel rope, forms automatically controlled removable counterweight by controller, counterweight motor, moving track, ballast pulley, pressure sensor; Pressure sensor is installed on the suspension centre of ballast, and pressure sensor connects controller, and controller connects the counterweight motor, and counterweight motor-driven ballast pulley moves on moving track;
Controller is a micro controller system.
The dynamical equilibrium building tower crane, building tower crane is under the situation that original counterweight does not move, utilize the principle of lever to make the tower crane arm be in relative horizontality, original fixed weight is changed over controlled movable balance weight, at ballast suspension centre setting pressure sensor, the lifting information that ballast will be received is passed controller back, controller calculates this counterweight for the required mobile distance of arm balance, send move, reach this apart from the time self-actuating brake, keep balance, ballast recomputates when mobile again, change directive, controller write down each mode of operation every day automatically, are convenient to needs such as data read and safety inspection.
The beneficial effect of dynamical equilibrium building tower crane of the present invention: change the unbalanced problem of domestic and international tower crane arm, move the relative equilibrium that realizes arm by counterweight, arm ballast weight, counterweight controller accurate Calculation, automatically counterweight moves around, reduce building tower crane inclination safety misadventure, reduce the life injury of tower crane the build labourer.
