Abstract
The utility model relates to front double load wheels for an electric pallet truck, which comprise a U-shaped wheel frame and two load wheels, wherein the load wheels are load wheels with stepped positioning bearings, the front double load wheels for the electric pallet truck also comprise two wheel frame shafts, each wheel frame shaft is T-shaped, the shaft in the up-right direction is a vertical shaft, installing holes are arranged at two sides of a horizontal cross bar, the installing holes at the two sides corresponding to the two wheel frame shafts are respectively used for installing the two load wheels by threaded shafts and nuts, and the vertical shafts of the two wheel frame shafts are respectively connected with the U-shaped wheel frame by a flanging steel back bearing and a thin adjusting pad, so that the two load wheels are positioned in an opening end of the U-shaped wheel frame. The front double load wheels can enable the whole loading capacity to be greatly enhanced, are suitable for rough road surfaces, and can conveniently pass through barriers such as grooves of elevator and the like.
Description
Technical field
The utility model belongs to the electric pallet truck technical field, is specifically related to be used for preceding pair of load-supporting wheel of electric pallet truck.
Background technology
It is little that electric pallet truck has a turn radius, the easy operating characteristics.Continuous expansion along with the electric pallet truck application; Electric pallet truck as in, the material transferring equipment of long distance adopts by most of user; This vehicle adaptable across the warehouse, places such as workshop, goods yard, shop, supermarket, should use on hard, smooth, smooth road surface usually.Before single load-supporting wheel structure be the common structure form that most of traditionally electric pallet trucks adopt; This structure is directly to link to each other preceding single load-supporting wheel with U type wheel carrier through preceding single-wheel axle; Have following problem in the application: 1, load-carrying capacity is not enough, causes that easily front-wheel damages; 2, preceding single load-supporting wheel axially has an assemblage gap, and single load-supporting wheel end float misalignment before being prone to cause has influenced the reliability of car load; 3, when running into the operating modes such as groove of uneven road surface and box elevator, the user is difficult for passing through, making troubles to manipulating, and causes the field of employment to receive very big restriction; 4, preceding single load-supporting wheel is difficult for getting into, withdrawing from the standard double empty pallet, makes user's operating difficulties, has limited the selection of user to the pallet model.Comprehensive above the analysis, preceding single load-supporting wheel is unfavorable for the application of electric pallet truck.
Summary of the invention
For the preceding single load-supporting wheel that solves electric pallet truck exist be not suitable for uneven road surface, can not be easily problems such as obstacles such as groove, load-carrying capacity deficiency through box elevator, the utility model provides a kind of preceding pair of load-supporting wheel that is used for electric pallet truck of improving structure.
The technical solution that realizes above-mentioned purpose is following:
The preceding pair of load-supporting wheel that is used for electric pallet truck comprises U type wheel carrier, two load-supporting wheel, and the both sides, rear portion of U type wheel carrier are respectively equipped with axis hole; Also comprise two wheel frame axles; Every wheel frame axle is a T shape; Wherein the axle of vertical direction is a vertical shaft, and the cross bar both sides of horizontal direction offer mounting hole respectively, and two the corresponding both sides of wheel frame axle mounting holes are provided with load-supporting wheel through threaded shaft and nut respectively; The vertical shaft of two wheel frame axles is connecting U type wheel carrier respectively, makes the open end of two the parallel U of the being positioned at type of load-supporting wheel wheel carriers.
Said load-supporting wheel is the load-supporting wheel that has the step location bearing.
Said nut is a thin nut.
The vertical shaft of said two wheel frame axles is being connected U type wheel carrier through the flange steel-backed bearing respectively with thin bearing cap shim.
The utility model is compared with traditional product and is had the advantage of following several respects:
1, to bear the propons load-bearing capacity jointly bigger than single load-supporting wheel for two load-supporting wheel parallel arranged, and two load-supporting wheel improve the load-carrying capacity of car load greatly, the service life of also having improved single load-supporting wheel relatively simultaneously;
2, the distance between the two load-supporting wheel axis of parallel arranged is reasonable in design, before having guaranteed effectively two load-supporting wheel devices can be applicable to uneven road surface and can be easily through obstacle such as elevator, groove and can successfully get into, withdraw from the standard double empty pallet;
3, to adopt customized design to have the bearing and threaded shaft one end of step location fastening with thin nut for load-supporting wheel, guaranteed that effectively two load-supporting wheel axially can play, have improved the reliability of car load;
4, the fuel feeding design is simplified in the application of self-lubricating flange steel-backed bearing, reduces maintenance and upkeep cost and time; Wear resisting property is good simultaneously, and friction coefficient is low, has prolonged the service life of steel-backed bearing and wheel frame axle;
5, reasonable integral structure, good looking appearance, dismounting is all convenient with maintenance.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2 and Fig. 3, the preceding pair of load-supporting wheel that is used for electric pallet truck comprises U type wheel carrier 4 and two load-supporting wheel 1, and load-supporting wheel 1 is for having the load-supporting wheel of step location bearing.The both sides, rear portion of U type wheel carrier 4 offer axis hole respectively.Also comprise two wheel frame axles 2; Every wheel frame axle 2 is a T shape; Wherein the axle of vertical direction is a vertical shaft, and the cross bar both sides of horizontal direction offer mounting hole respectively, and two wheel frame axle 2 corresponding both sides mounting holes are installed with load-supporting wheel 1 through threaded shaft 3 and thin nut 6 respectively; To guarantee that two load-supporting wheel 1 axially can play, to guarantee that simultaneously two load-supporting wheel 1 all can go slick, freely rotate; The vertical shaft of two wheel frame axles 2 is being connected U type wheel carrier 4 through flange steel-backed bearing 5 with thin bearing cap shim 7 respectively, makes the open end of two load-supporting wheel, the 1 parallel U of being positioned at type wheel carrier; Flange steel-backed bearing 5 guarantees that two wheel frame axles 2 all can go slick, simultaneously through thin bearing cap shim 7 adjustment endplays.
During use, the utility model is installed on the vehicle body through the axis hole of both sides, U type wheel carrier 4 rear portion.
