The specific embodiment
Further specify concrete structure of the present utility model and operating principle below in conjunction with accompanying drawing.
As shown in drawings, the power line draw off gear of the electric pallet truck of the utility model, it has support (2), the top of support is equipped with upper bearing sleeve (11) and lower bearing sleeve (7) by pole (34), on, be separately installed with bearing (40) and another bearing (38) in the lower bearing sleeve, the two bearings installed inside has sleeve (12), the upper end of sleeve is fixed with carriage (13), the upper end that the bottom is installed in the hawser (4) on the assembly pulley (3) is wrapped on the runner (15), runner is installed in the rotating shaft (14) at carriage rear portion, another runner (35) also is installed in the rotating shaft, the other end of the rope that twines on another runner (16) is wrapped in another rotating shaft (36) at carriage middle part, the other end that is fixed on the last wire rope (22) that twines of the 3rd runner (17) in another rotating shaft (36) is connected the top of the vertical rod (25) on the forklift body (31), there is insulating cylinder (39) outside of sleeve, on three sheet metals (10) that three power lines (8) of three-phase alternating current insulate between being connected to mutually, each sheet metal is installed on the elastic plate (9), and fit together with three metal rings (33) of the outside suit of insulating cylinder, one end of other three power lines (37) passes sleeve respectively and is connected on three metal rings (33), the middle part is lifted on the wire rope (22) by a plurality of rollers (20), the other end is connected on other three sheet metals (23) in the vertical rod, these three sheet metals are installed on another elastic plate (26), and fit together with three metal rings (24) of vertical rod upper end, the upper end of the power line (41) in the vertical rod passes vertical rod respectively and three metal rings link together, and balancing weight (1) is arranged below the assembly pulley (3).
The lower end of power line (41) is connected on frequency-variable controller (27) inlet side, and the power line that frequency-variable controller goes out end is connected on the interior dc motor (29) of forklift body, and the axle of dc motor links together with the power shaft (30) of main spindle box (32).
On the forklift body, except that having now motor on the forklift changes dc motor into and power shaft (30) on the main spindle box is connected, other do not change substantially.The control button of frequency-variable controller (27) etc. is arranged in the driver's cabin, by the action of forklift driver control electric pallet truck.The particular circuit configurations of frequency-variable controller is a prior art, no longer describes in detail.
Can there be cable sheathing (21) outside at other three power lines (37) middle part, to play a protective role.Roller (20) can be installed in the outside of cable sheathing.
Three power lines (8) of three-phase alternating current are connected on the power supply.
When electric pallet truck straight line to overtake the time, forklift pulling wire rope is gone up around down from the 3rd runner (17), and other three power lines (37) also extend.The 3rd runner drives another rotating shaft (36) and rotates when rotating, and then rotates by rope (16) drive rotating shaft (14), and rotating shaft (14) drives runner (15) and rotates, thereby hawser (4) is wound up, and hawser rises balancing weight by assembly pulley.Obviously, the distance that forklift travels is far away more, wire rope around under long more, it is high more that balancing weight rises.When forklift such as turned round at curve driving, moving of forklift positions promptly rotated in upper and lower bearing holder (housing, cover) by wire rope, carriage tape moving sleeve (12), and sleeve three metal rings (33) outward rotate with sleeve.Owing to the elastic plate (9) of default elastic force is arranged, makes three sheet metals (10) in the sleeve rotating process, be fitted on three metal rings (33) always; Annexation between three metal rings (24) of three sheet metals (23) and vertical rod upper end similarly.Like this, in the process of forklift curve driving (even around 360 ° of turnings of support), power supply passes on the frequency-variable controller, and then passes on the dc motor through each root power line, sheet metal, metal ring.When forklift retreated, under the action of gravity of balancing weight, hawser (4) was decontroled, and drives each runner, rotating shaft backward rotation, and wire rope is wrapped on the 3rd runner (17), and other three power lines (37) are also drawn in.
Between elastic plate and support, also can be connected with extension spring, lean on the elastic force of extension spring that sheet metal is fitted on the metal ring.
Drive power shaft (30) rotation of main spindle box (32) during dc motor work by its axle, the output shaft of main spindle box drives the various operation acts of finishing forklift.Main spindle box (32) is the main spindle box on the existing forklift.
At the middle part of described support (2) limit switch (5) is arranged, touching lever (6) is arranged on the limit switch.When contacting (being that forklift drives to maximum working radius) when balancing weight rises to touching lever, limit switch action, powered-down.Limit switch is a kind of travel switch.
Front end at described carriage (13) is equipped with the 4th runner (18), wire rope (22) be positioned at the 4th runner below.The 4th runner plays the tensioner effect to wire rope.
Be hinged with a pair of clamping bar (19) foremost at described carriage (13), wire rope (22) is between this is to clamping bar.Clamping bar plays the barrier effect of pair roller (20), twines on the 3rd runner (17) with wire rope to prevent it.
Can there be automatic brake holding device (28) outside of the power shaft (30) of main spindle box (32).Identical on the equipment such as the concrete structure of this device and hoist engine no longer described in detail.
The guard shield of protective action can be set at the top of top, bottom and the vertical rod of support.
