Abstract
The invention discloses a manual adjusting device for the fork arm space of a forklift. The invention belongs to devices for adjusting the fork arm space of a forklift, and in particular relates to a manual adjusting device for the fork arm space of the forklift. According to the adjusting device, racks are fixedly installed at a fork frame cross beam of the forklift longitudinally; a gear shaft is installed at a side surface of a fork arm in a structure of a rotation pair; a gear is made integrally with the gear shaft; the gear is meshed with the rack; and the cross section of the end part of the gear shaft is a quadrangle or a hexagon. By adoption of the adjusting device, the fork arm space of the forklift can be manually adjusted freely, the structure is simple, the installation is convenient, the use is convenient and rapid, the operation is simple, the labor and time are saved, the application range is wide, and a conventional forklift structure is not changed at all.
Description
Technical field
The invention belongs to the setting device of setting device fork truck yoke spacing, specifically a kind of manual adjusting device of fork truck yoke spacing.
Technical background
At present, in the carrying fork truck operation, automatically transfer the fork truck of fork system for nothing, the comparatively heavy fork truck of load-carrying more than 3 tons of yoke particularly, the spacing of adjusting between the yoke all is to adjust by the mode that the people tries hard to recommend or draws, tool is a great inconvenience, and has certain potential safety hazard, and labor intensity of operating staff is large.
Summary of the invention
Adjust difficulty in order to overcome without the fork truck yoke spacing of automatically transferring the fork system, the low deficiency that waits of efficient, the purpose of this invention is to provide a kind of fork truck yoke spacing manual adjusting device, can carry out manually freely adjusting to fork truck yoke spacing, this device is easy for installation, easy to use, applied range is to having fork lift truck structure now without any change.
The technical solution used in the present invention is: the crotch crossbeam at fork truck vertically is installed with tooth bar, structure in the side of yoke with revolute pair is equipped with gear wheel shaft, gear and gear wheel shaft manufacture one, and wheel and rack is meshed, and cross section, gear wheel shaft end is quadrangle or hexagon.
Concrete technical scheme of the present invention is, tooth bar is installed in the end face that is loaded on again the crotch crossbeam behind the L shaped tooth bar seat, and gear wheel shaft is installed in the side of yoke by gear shaft block, is provided with the bearing of gear wheel shaft in the gear shaft block.
The working process of this device: when fork truck need to be adjusted the yoke spacing, unclamp first the yoke lock bolt, then be inserted in the polygon end of gear wheel shaft with free wrench, the turning gear wheel shaft, under the effect of tooth bar to gear, yoke is pushed, thereby realizes the adjustment of yoke spacing.Take 8 ton forklift yokes as example, contain average every meter of setup time only to adjust about 1 minute half of needs.Adjust to need the position after, take off free wrench (it is connected with gear wheel shaft is movable, and the time spent is loaded onto, and the time spent is desirable lower), yoke lock screw return, the yoke adjustment is finished.
Beneficial effect of the present invention is: fork truck can be realized the requirement of yoke maximal work position by installing and using the yoke spacing regulator.Can realize that minimum spacing (being the inboard spacing of pallet fork two pallet forks when closing up) is 0, only than the little 160mm of maxim of erecting device not, this is automatically to transfer fork system unappeasable maximal work position to maximum spacing (being the outside spacing of pallet fork two pallet forks when opening).This apparatus structure is simple, and is easy for installation, design ingenious, simple to operate, can Effective Raise the yoke regulated efficiency, field of application is wider, and to existing fork lift truck structure without any change.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is local structure enlarged drawing of the present invention.
Among the figure: tooth bar seat 1, tooth bar 2, back-up ring 3, gear shaft block 4, gear 5, yoke 6, crotch crossbeam 7, bolt 8, gear wheel shaft 9, bolt 10.
The specific embodiment
Below in conjunction with accompanying drawing embodiment, the present invention is further illustrated.
Referring to Fig. 1,2, the main parts size of this device is: tooth bar seat 1; Tooth bar 2; Back-up ring 3; Gear shaft block 4.Tooth bar 2 is connected with L shaped tooth bar seat 1 usefulness countersunk-heat bolt 8, and then be installed on the crotch crossbeam 7 of fork truck, again with in the gear shaft blocks 4 of packing into such as gear wheel shaft 9 and corresponding bearing, back-up ring 3, then respectively the gear shaft block 4 of two cuff gear wheel shafts 9 is installed on the side of two yokes 6, should guarantees the tooth section back lash of tooth bar 2 and gear 5 during installation.After install finishing, according to the yoke spacing requirement that will adjust, mix standard cartridges by free wrench, six square end heads of turning gear wheel shaft 9, yoke just can along with the rotation of gear 5 along tooth bar 2 sway, adjusting to needs the position.
Claims (2)
1. fork truck yoke spacing manual adjusting device, it is characterized in that: the crotch crossbeam at fork truck vertically is installed with tooth bar, structure in the side of yoke with revolute pair is equipped with gear wheel shaft, gear and gear wheel shaft manufacture one, wheel and rack is meshed, and cross section, gear wheel shaft end is quadrangle or hexagon.
2. by claimed in claim 1, it is characterized in that: tooth bar is installed in the end face that is loaded on again the crotch crossbeam behind the L shaped tooth bar seat, and gear wheel shaft is installed in the side of yoke by gear shaft block, is provided with the bearing of gear wheel shaft in the gear shaft block.
