Abstract
The utility model relates to a torsion spring balance-type vertical lift gate in an industrial door, in particular to a deflection regulating device used on a middle beam of the industrial door. The deflection regulating device used on the middle beam of the industrial door solves the defect that a driving shaft (and an auxiliary shaft) on a conventional industrial door sinks and deforms caused by gravity, and comprises a steel wire rope tension regulator and steel wire ropes, wherein the steel wire ropes are connected with both sides of the steel wire rope tension regulator; steel wire rope supporting rods are arranged on the steel wire ropes on the both sides; a pulley is arranged at one end of each steel wire rope supporting rod; and the steel wire ropes wind around the pulleys and are connected with the steel wire rope tension regulator. The deflection regulating device can effectively eliminate the sinking and the deformation of the middle beam, improves the straightness of the driving shaft (and the auxiliary shaft), ensures the installation quality of the vertical lift gate, shows up the balance effect of gravitational loading, and prolongs the service life for operation.
Description
Technical field
The utility model relates to the torsion spring balanced type vertical-lift door in the industrial door, particularly a kind of deflection adjusting device that is used on the industrial door offset beam.
Background technology
In the existing torsion spring balanced type vertical-lift door, set up the driving shaft that moves the door body with offset beam, the conical drum that is used for the overhead door body, the torsion spring assembly that the balancing gravity load is used, the support of bearing that sets up driving shaft and drive motors etc. are housed on the driving shaft.Balance torsion spring assembly required when the door opening height is big is more, to set up asessory shaft when the installation site on the driving shaft is not enough at this moment, asessory shaft need be erected on another root offset beam, this offset beam is parallel with the offset beam that sets up driving shaft, transmits the torque of spring between asessory shaft and the driving shaft with chain drive.Because offset beam bears the influence of the factors such as gravity load of the gravity load of gravity load, spring assembly of a body and bearing spider, can produce corresponding sagging distortion after the installation, cause driving shaft (and asessory shaft) under case of bending, to move, increased the load of drive motors, reduce the fatigue life of driving shaft (and asessory shaft), the counterbalance effect variation.
Summary of the invention
The technical assignment that the utility model proposes is that the driving shaft (and asessory shaft) that solves on the existing industrial door produces the defective of sagging distortion because of the gravity reason, a kind of deflection adjusting device that is used for the industrial door offset beam is provided, described deflection adjusting device can effectively be eliminated the sagging distortion of offset beam, improve the glacing flatness of driving shaft (and asessory shaft), ensure the installation quality of vertical-lift door, the counterbalance effect that manifests gravity load, prolongation service life.
The technical scheme that the utility model technical solution problem adopts: be used for the deflection adjusting device on the industrial door offset beam, comprise lineoutofservice signal pull adjuster and the wire rope that is connected in its both sides, respectively be provided with a wire rope support bar on the wire rope of both sides, wire rope support bar one end is provided with pulley, and described wire rope is walked around pulley and is connected with the lineoutofservice signal pull adjuster.During use wire rope two is fixed in the offset beam two ends of driving shaft (and asessory shaft), two wire rope support bar symmetries are fixed under the offset beam, adjust pull of steel wire by the draft regulator in the middle of the two steel wire bracing frames and make bracing frame one end pressurized, other end pushing tow offset beam upwards arches upward behind the bracing frame pressurized, allow offset beam amount of deflection that arches up and the sagging amount of deflection that offset beam produces because of action of gravity equate to eliminate the sagging distortion of offset beam as long as adjust pull of steel wire, make driving shaft (and asessory shaft) in straight state turning down, improve the glacing flatness of driving shaft (and asessory shaft), ensure the installation quality of vertical-lift door, the counterbalance effect that manifests gravity load, prolong service life.The installation direction conversion of two wire rope support bars can influence regulating effect once, presses direction set among Fig. 1～Fig. 3, and support bar only bears pressure; If installation direction changes, support bar also bears additional bending moment, reduces the intensity of support bar.
Described wire rope two ends are respectively equipped with installing rack.The effect of installing rack is to be convenient to fixedlying connected of wire rope two and offset beam.
Be provided with wire tensioner between described lineoutofservice signal pull adjuster and the wire rope.Wire tensioner is used to regulate pull of steel wire, adopts (GB/T3818-1999) standard.
The utility model is eliminated the sagging distortion of offset beam by adjusting pull of steel wire, realizes that main shaft moves under straightened condition, thereby improves the installation quality and the service life of industrial door.
