Description
Technical field
The present invention relates to engineering technical field of crane equipment, particularly relate to a kind of tower crane structure with weight detecting.
Background technology
Tower crane is that a kind of weight-lifting equipment the most frequently used on building ground has another name called tower crane, and be used for hanging the raw MAT'L of the constructions such as working reinforcing bar, wood are stupefied, cement concrete, steel pipe, tower crane is a kind of requisite equipment on building site.The function of tower crane point bears the upper load that jib stay cord and equilibrium arm stay cord transmit, and directly pass to tower body structure by turntable by the structure member formula of revolution pylon, turntable, bearing etc., there is truncated cone pillar from rising tower top, leaning forward or hypsokinesis truncated cone pillar, herringbone posture and diagonal brace posture.Common tower crane generally comprises base, tower body, arm, hook composition, after arm slings weight, first carries on weight, and after above mentioning certain altitude, whole arm rotates, thus weight is moved to the position of demand.In actual mechanical process, after hook is connected with weight, weight is aerial at height at lifting moment, weight, the steel cable stretching force of winch can change, and the tensile property of cable wire is constant, therefore, even if the gravity of some weight is within the tension scope of cable wire, in lifting moment, receive windage etc. aloft, the gravity of weight may exceed the rated load of cable wire, there is potential safety hazard in cable wire overload state.
Summary of the invention
The present invention, in order to solve above-mentioned deficiency of the prior art, provides a kind of energy inspected object weight in real time, thus judges whether object is in cable wire load range to the pulling force of cable wire, use safer tower crane structure.
To achieve these goals, the present invention adopts following technical scheme:
A kind of tower crane structure with weight detecting, comprise base, be vertically fixed on the tower body on base, the top of tower body is provided with arm, one end of arm is provided with counterweight matrix, winch, the other end of arm is provided with pulley, cable wire on winch is walked around pulley and is connected with arm, the below of cable wire is provided with hook, the middle part of described arm is provided with rotating disk, be rotationally connected between described rotating disk and tower body top, described pulley is provided with adapter shaft, the bottom of described hook is provided with connecting panel, the outer end of connecting panel is provided with support ring, the outer end of support ring is provided with cover plate, connecting panel, support ring, between cover plate, bolt connects, the center of described cover plate is provided with centre hole, the outer end of described adapter shaft is stretched in centre hole, the outer end of adapter shaft is provided with anticreep baffle plate, pressure sensor is provided with between described anticreep baffle plate and cover plate the inner, the outer end of described cover plate is provided with the warning light be connected with pressure sensor.After hook is connected with weight, winch draws cable wire in, in weight lifting process, pressure sensor can detect the gravity of weight in real time, after the gravity of weight exceeds safe range, and the shinny warning of warning light, thus alert operator weight is overweight, because of emergency treatment, use safer.
As preferably, between described anticreep baffle plate and pressure sensor, be also provided with the thrust baring be set on adapter shaft.After anticreep baffle plate and pressure sensor compress; can rotate because weight is subject to the impacts such as wind-force aloft; now can relatively rotate between adapter shaft and cover plate; thrust baring passes to pressure sensor moment of torsion when can prevent adapter shaft from rotating, thus plays a protective role to pressure sensor.
As preferably, be provided with stage clip between described anticreep baffle plate and cover plate, described stage clip is positioned at the outside of pressure sensor.When not having weight on linking up with, stage clip makes to form gap between pressure sensor and anticreep baffle plate, prevents pressure sensor to be in pressured state always, plays a protective role to pressure sensor.
As preferably, the outside of described warning light is provided with transparent lamp shade.Transparent lamp shade plays a protective role to warning light.
As preferably, the downside that described tower body upper end is positioned at rotating disk is provided with annular steel cage, the balance weight ring that can rotate around tower body is provided with in annular steel cage, on described tower body, between rotating disk and annular steel cage, the side at position is provided with double end motor, the upper end of described double end motor drives dial rotation, the lower end driven equilibrium counterweight ring of double end motor rotates, the described rotation direction of balance weight ring and the direction of rotation of rotating disk.When double end driven by motor dial rotation; thus when driving arm to rotate; the lower end of double end motor is with dynamic balance weight ring to rotate simultaneously; the rotation direction of balance weight ring and the direction of rotation of arm; therefore arm rotate to tower body produce moment of torsion, balance weight ring rotate to tower body produce torque direction contrary; can cancel out each other, thus reduce the impact of arm rotary torque on tower body greatly, thus tower body is played a protective role.
As preferably, the upper end of described double end motor is provided with drop-gear box, the lower end of double end motor is provided with lower drop-gear box, the output shaft of upper drop-gear box, lower drop-gear box is respectively equipped with the gear of rotating in same direction, the downside of described rotating disk is provided with outer tooth ring, gears meshing on the outside of described outer tooth ring and upper drop-gear box, the upside of described balance weight ring is provided with internal gear, the gears meshing on the inner ring of described internal gear and lower drop-gear box.Upper drop-gear box, lower drop-gear box can regulate the rotating speed of double end motor, can increase the output loads of double end motor simultaneously.
As preferably, described balance weight ring comprises some pieces of counterweight elements, and adjacent counterweight element is fixedly connected into balance weight ring by pipe link successively.Balance weight ring is assembled by some pieces of counterweight elements, assembled, easily manufactured, easy for installation.
Therefore, the present invention has following beneficial effect: (1) is inspected object weight in real time, if weight exceedes cable wire safe range in lifting process, alarm lamp sends warning; (2) balance weight ring energy balancing torque, reduces arm driving torque to the impact of tower body, keeps the connective stability of tower body and base, use safer.
