Abstract
The utility model relates to an automatic regulation movable counterweight device, which belongs to three-way electric forklift counterweight devices. The utility model is composed of a track (1) and a movable counterweight block (4), wherein the upper surface of the track (1) is provided with two slide ways (5), and a primary pole (2) is fixed on a convex table between the two slide ways (5); two lug bosses are arranged below the counterweight block (4) and movably installed in the slide ways (5) of the track (1), and a secondary pole (3) which is arranged between the two lug bosses is fixed on the counterweight block (4) and corresponds to the primary pole (2). When the automatic regulation movable counterweight device is installed on a three-way forklift, a secondary motion direction can be achieved by changing electricity switching phase sequence of primary coils to balance overturning moments of a forklift; the utility model ensures stable work of the forklifts and can not cause overturn accidents.
Description
Technical field
The utility model belongs to three electri forklift counter weight devices, and particularly a kind of automatically regulating moves counter weight device.
Technical background
At present, the counterweight of three electri forklifts dress is fixed clump weight, and when the fork truck side fork was got goods, the capsizing moment of generation can cause the horizontal instability of fork truck, can cause roll-over accident when serious.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provide a kind of three-dimensional fork truck when side fork is got weight, can automatically counterweight be moved with the balance capsizing moment the automatically regulating counter weight device.
The technical scheme that the utility model technical solution problem adopts is: a kind of moving counter weight device of being made up of track and clump weight of automatically regulating, be characterized in being provided with above the track two slideways, fix on the boss in the middle of two slideways one elementary, be provided with two boss below the clump weight, boss is contained in the slideway of track versatilely, and two one of boss center fixed are secondary and elementary corresponding, elementary several grooves that is provided with, several coils 7 are housed in the groove, secondary a sliver are housed.
The beneficial effects of the utility model are: when three fork trucks are adorned the moving counter weight device of this automatically regulating, the energising phase sequence that changes its primary winding just can obtain the collateral motion direction, come balance fork truck capsizing moment, guaranteed the smooth working of fork truck, can not cause roll-over accident.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 shows that automatically regulating moves the counter weight construction block diagram.
Elementary, the secondary work schematic diagram of Fig. 2 diagrammatic sketch 1.
Among the figure, the 1-track; 2-is elementary; 3-level; The 4-clump weight; The 5-slideway; The 6-sliver; The 7-travelling-magnetic-field; The 8-coil
The specific embodiment
With reference to accompanying drawing, a kind of automatically regulating counter weight device of forming by track 1 and moving clump weight 4, be provided with above the track 1 fix on the boss in the middle of 5, two slideways of two slideways 5 one elementary 2, be provided with two boss below the clump weight 4, boss is contained in the slideway of track 1 versatilely, two boss center fixed on clump weight 4 one secondary 3 corresponding with elementary 2, certain interval is arranged between them, elementary 2 are provided with five grooves, five coils 7 are housed in the groove, and the inferior utmost point 3 is equipped with a sliver 6.
Its principle of work (seeing accompanying drawing 2), when the coil 5 when elementary 1 feeds three electric currents, can produce the travelling-magnetic-field 7 that straight line moves, sliver 6 under the effect of travelling-magnetic-field 7 in secondary 3 will produce inducing current, this electric current and travelling-magnetic-field 7 mutual actions, just produce tangential electromagnetic force, when elementary 2 motionless, secondary 3 will drive clump weight 4 does straight-line motion along the direction of travelling-magnetic-field 7 along the slideway 5 of track 1, change the energising phase sequence of the coil 8 in the straight line elementary 2, can change secondary 3 sense of motion, thereby it is mobile to the left or to the right along the slideway 5 of track 1 to obtain clump weight 4, come the capsizing moment of balance fork truck, guarantee the smooth working of fork truck, can not cause roll-over accident.
Claims (1)
1, the moving counter weight device of a kind of automatically regulating, form by track (1) and moving clump weight (4), it is characterized in that on track (1), being provided with two slideways (5), fix one elementary (2) on the boss in the middle of two slideways (5), be provided with two boss below the clump weight (4), boss is contained in the slideway (5) of track (1) versatilely, and two boss center fixed are corresponding with elementary (2) at clump weight (4) last secondary (3).
