Abstract
The utility model relates to a saw horse elevating device of a gantry horizontal sawing machine. The saw horse elevating device comprises a transmission and a saw horse, and is characterized in that: the transmission is connected with a reverser; both sides of the reverser are symmetrically connected with lead screw elevators with the same performance; each lead screw elevator is connected with an elevating nut which moves vertically; and the elevating nut is connected with the saw horse. A transmission device has high saw horse driving synchronism, directly acts on the saw horse, so that the feeding stability of the saw horse is high; and the transmission can make the saw horse feed rapidly, feed slowly and retract rapidly, so that the working efficiency of the device is improved, and the phenomena of tooth breaking and belt breaking of a saw belt are avoided.
Description
Technical field
The utility model relates to a kind of sawing machine, relates in particular to a kind of saw frame lowering or hoisting gear of horizontal saw mill.
Background technology
At present, the saw frame lowering or hoisting gear on the horizontal saw mill of gantry generally adopts two oil cylinder transmissions, and the two secondary Connection Blocks that gantry saw frame sets up separately by its back side slide feeding along corresponding rectilinear orbit on the column.But because biliquid compressing cylinder poor synchronization, make gantry saw frame when feeding, have stable unfavorable problem, cause easily that thus saw band beats tooth or broken belt, cause shut-down, both lost time, influence the raising of production efficiency, also improved production cost.In order to improve the synchronism of sawing machine saw frame, Chinese patent 2637061 discloses a kind of line slideway gantry horizontal band sawing machine.It comprises saw frame, guideway, column and support.Column is installed on the support, guideway is straight-line rolling guide set, and slide block in the guideway and guide rail are installed in respectively on the saw frame back side and two columns, slide block and guide rail corresponding matching, two guide rail linearity height have improved saw frame feeding stationarity to a certain extent.
Summary of the invention
The utility model main purpose is: develop the saw frame lowering or hoisting gear of a kind of gantry horizontal saw mill, have stability and reliability thereby further improve saw frame when feeding.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: the saw frame lowering or hoisting gear of a kind of gantry horizontal saw mill, has speed changer, saw frame, it is characterized in that: described speed changer links to each other with commutator, be connected with to described commutator bilateral symmetry the identical screw lift of performance, be connected with the lifting nut that moves both vertically on the described screw lift, described lifting nut links to each other with saw frame.
The technical solution of the utility model can also be further perfect:
As preferably, described commutator is provided with connecting bushing, on the described screw lift shaft joint is housed, and links to each other by connecting axle between described connecting bushing and the shaft joint.
As preferably, there is lead screw of elevator the lower end of described screw lift, the described lifting nut component movement pair that matches with lead screw of elevator.
The beneficial effects of the utility model:
1, the utility model is owing to adopted commutator, screw lift to connect lifting nut, and lifting nut links to each other with saw frame, makes that the synchronism of this transmission device drive saw frame is good, and directly acts on the saw frame, so the stability of its saw frame feeding is high.
2, can make saw frame fast feed, feeding and rapid return at a slow speed by speed changer, improve the operating efficiency of device greatly.
The precision of centripetal force uniformity and saw frame motion all is improved the favourable generation of avoiding saw band to beat tooth and belt phenomenon during 3, owing to saw band work.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
The specific embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
As shown in the figure, a kind of gantry horizontal band sawing machine vertical feed device is made up of commutator 5, connecting bushing 4, connecting axle 3, shaft joint 2, screw lift 1, lead screw of elevator 6 and lifting nut 7.Be connected with the identical screw lift of performance 1 to described commutator 5 bilateral symmetry, described commutator 5 is provided with connecting bushing 4, on the described screw lift 1 shaft joint 2 is housed, and links to each other by connecting axle 3 between described connecting bushing 4 and the shaft joint 2.There is lead screw of elevator 6 described screw lift 1 lower end, and lifting nut 7 is housed on the described lead screw of elevator, and both match and form the screw mandrel kinematic pair; Described lifting nut 7 links to each other with saw frame.
During work, commutator 5 links to each other by the motor shaft joint with drive motors (through speed changer) on being installed in portal frame, and lifting nut 7 links to each other with saw frame.Drive the saw frame fast rise, descend fast or descend at a slow speed by the drive motors rotating.
Therefore, the utility model drives the saw frame motion by commutator, screw lift and lifting nut, makes this transmission device directly act on the saw frame, realizes that the saw frame lifting is synchronous, and stability is high, the favourable generation of avoiding saw band to beat tooth and belt phenomenon.
