Abstract
The utility model discloses a multifunctional electric stair-climbing hand truck. The multifunctional electric stair-climbing hand truck comprises a truck frame, a travelling wheel set and a drive device, wherein the travelling wheel set is arranged at the bottom side of the truck frame, and the drive device drives the travelling wheel set to rotate; the drive device is arranged on the bottom side of the truck frame and detachably installed in a drive rack on the truck frame; the drive device comprises a motor, a motor shaft of the motor is connected with the input end of a worm reduction box, and the output end of the worm reduction box is connected with a transmission shaft; the two ends of the transmission shaft penetrate through the drive rack and respectively connected to the middle of a triangular wheel stand in the middle of the travelling wheel set; travelling wheels are evenly distributed and installed at three top angles of the triangular wheel stand respectively. Compared with a common stair climbing tool, the multifunctional electric stair-climbing hand truck integrates multiple functions, and different use functions can be achieved by allowing the drive device to be connected with different truck frames. Meanwhile, the defects that according to the common stair climbing tool, a reduction box cannot be self-locked, landing and steering through four wheels are difficult, and axle distances are simplex are overcome.
Description
Technical field
The utility model relates to a kind of handling machinery, is specifically related to a kind of Multifunctional electric stairs climbing car.
Background technology
At present, on market, the weak point of common cart for travelling up or down stairs is mainly: 1, common cart for travelling up or down stairs is normally that integral solder forms by actuating device and vehicle frame, handle, belongs to special train special-purpose, function singleness, restricted application.What 2, actuating device adopted conventionally is ordinary gear drop-gear box, there is no auto-lock function, and in the time of downstairs, under the effect of weight, more race is faster, is difficult to control, and has great potential safety hazard.3, during level road, four wheels of common cart for travelling up or down stairs triangle wheels land simultaneously, cause wheel and ground friction to strengthen, and turn to heavily on the one hand, and during loads, direction is difficult to control, and in addition, wheel serious wear, has shortened service life.4, the top of common cart for travelling up or down stairs three caster racks only has a wheel installation position, can not select suitable installation position according to step specification.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of Multifunctional electric stairs climbing car simple in structure, easy to use, applied widely is provided.
A Multifunctional electric stairs climbing car, comprises vehicle frame, the actuating device that is arranged on the walking wheels of vehicle frame bottom side and drives walking wheels to rotate; Described actuating device is arranged on vehicle frame bottom side, is detachably arranged in the drive chassis on vehicle frame, described actuating device comprises motor, the motor shaft of described motor is connected with the input end of worm reduction box, mouth is connected with transmission shaft, transmission shaft two ends are connected to the three caster rack middle parts at walking wheels middle part through drive chassis, road wheel is uniform three drift angle places that are arranged on three caster racks respectively.
On described vehicle frame, also add electric-control system, described electric-control system comprises electric control operation handle and the storage battery connecing with its electricity, and described storage battery is arranged in drive chassis.
The utility model is compared with the common building instrument of climbing, and has the feature of one-machine-multi-function, and an actuating device connects different vehicle frames and can realize different use functions.Meanwhile, solved common climb building instrument drop-gear box can not self-locking, four-wheel lands and turns to the shortcoming of difficulty, single wheel base.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of actuating device in the utility model.
Fig. 3 is use view of the present utility model.
Fig. 4 is structural representation of the present utility model (cart type vehicle frame).
Fig. 5 is structural representation of the present utility model (wheel chair type vehicle frame).
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Referring to Fig. 1, a kind of Multifunctional electric stairs climbing car that the utility model provides, comprise vehicle frame 1, the actuating device 3 (as shown in Figure 2) that is arranged on the walking wheels 2 of vehicle frame 1 bottom side and drives walking wheels 2 to rotate, in use, actuating device 3 provides power for walking wheels 2, and each road wheel 2d of walking in wheels 2 circulates successively and touch mutually (referring to Fig. 3) with steps 4 at different levels, completes building (comprise upstairs and the downstairs) process of climbing.
In order to solve the problem described in background technology, the technical solution of the utility model is, described actuating device 3 is arranged in the drive chassis 5 of vehicle frame 1 bottom side, comprise motor 3a, the motor shaft of described motor 3a is connected with the input end of worm reduction box 3b, mouth is connected with transmission shaft 3c, and transmission shaft 3c two ends are connected to the three caster rack 2a middle parts at walking wheels 2 middle parts through drive chassis 5, and road wheel 2d is uniform three drift angle places that are arranged on three caster rack 2a respectively.
Referring to Fig. 4, Fig. 5, described vehicle frame 1 can adopt multiple pattern, such as wheel chair type, and cart type etc., drive chassis 5 is detachably arranged on vehicle frame 1, by changing the vehicle frame 1 of difference in functionality, realizes difference in functionality; Adopt worm reduction box, overcoming downstairs can not self-locking and the problem that lands of level road four-wheel, has eliminated hidden danger, has reduced the wearing and tearing of wheel; Three caster rack 2a drift angle installation positions, can select suitable selection according to step specification.
Further improvement as to embodiment 1, improves handling of the present utility model, can on vehicle frame 1, install electric-control system additional, and described electric-control system comprises electric control operation handle 1a and the storage battery 1b connecing with its electricity, and described storage battery 1b is arranged in drive chassis 5.When reality is used, electric control operation handle 1a can be arranged on to the grip of vehicle frame 1, be convenient to controlling performances such as car load running velocitys.
Certainly in electric-control system, setting up the elements such as controller, two-direction switch, speed regulator, battery indicator, speed regulator, battery indicator realizes different electric control functions, is prior art, therefore do not repeat in the present embodiment.
