The utility model is characterized in that the utility model is composed of a handcart body, a main shaft, fork wheels, a clutch device, a brake device, an engine, a transmission shaft, and a transmission device. The main shaft is arranged on the lower of the handcart body, a clutch fork wheel and the clutch device are arranged on one end of the main shaft, permanent rotary fork wheel is arranged on the other end of the main shaft, and the driving shaft of the engine is provided with a chain wheel. The chain wheel drives the transmission device composed of a chain and the chain wheel to transmit the main shaft. The utility model can carry things or people up or down stairs by a motor or by a hand. The utility model can perform hill climbing in the field. The utility model has the advantages of convenient turning, and flexible operation.
Description
The utility model relates to a kind of stair activity car, mainly keeps supplying and goes downstairs and the usefulness of manned or loading during open-air climbing.
Up to now, the car that does not still have this kind purposes.
The purpose of this utility model is to fill up the blank of this area and a kind of power operated stair activity car is provided.
The purpose of this utility model can reach by following measure: the utility model is made up of car body, main shaft, fork wheel, arrangement of clutch, brake gear, driving engine, transmission shaft and driving device, car body middle part down has main shaft, main shaft one end is equipped with clutch fork wheel and arrangement of clutch, main shaft end in addition is equipped with the permanent fork wheel that rotates, engine drive shaft has sprocket wheel, and sprocket wheel drives the driving device transmission main shaft that is made of chain and sprocket wheel.
The drawing of accompanying drawing is described as follows:
Fig. 1 is total figure of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the lateral plan of Fig. 1;
Fig. 4 is the plane arrangement structure scheme drawing of trident wheel car of the present utility model and four fork wheel cars;
Fig. 5 is the Retractive leg section-drawing of fork wheel;
Fig. 6 is the local rotation of an arrangement of clutch enlarged drawing;
Fig. 7 is sliding dynamic interlocking teeth wheel section-drawing;
Fig. 8 is a fixedly tooth embedding wheel section-drawing;
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing: referring to Fig. 1-Fig. 3, car body 1 is the uncovered rectangular box body of hollow, for loading usefulness, as need manned (mainly referring to the disabled person), then must increase seat.Car body middle part down has main shaft 2, main shaft two ends that the fork wheel is arranged, and is provided with 3-10 bifurcated, and present embodiment is the fork wheel of five bifurcateds 3.Fork wheel persevering rotation fork wheel and clutch fork wheel, the fork wheel comprises bifurcated and Retractive leg.Pack into the square shaft 6 of main shaft this end of the persevering rotation of one end of main shaft (lower end shown in Figure 2) fork wheel 4, the square hole 5 of fork wheel 4 central authorities, axle head is fastening with nut 7, like this, just can guarantee to pitch and take turns 4 and rotate with main shaft.The end (upper end shown in Figure 2) in addition of main shaft has clutch fork wheel 8 and arrangement of clutch.Referring to Fig. 6-Fig. 8, there is the bearing 9 that is loaded on the main shaft in clutch fork wheel central authorities.Arrangement of clutch comprises fixedly tooth embedding wheel 10 and sliding dynamic interlocking teeth wheel 11, and fixed wheel 10 is welded on bearing 9 outer rings and with outside race and clutch fork wheel and rotates, and sliding dynamic interlocking teeth wheel center has spline tube to be loaded on the castellated shaft position of main shaft and can be in axial sliding along spline.When the utility model in running condition need turn round, handle the handle 14 that is positioned on the vehicle frame 13 and make it affect steel cable (not shown on the figure), the good driving wheel of interlock 11 is retreated reset, deciding driving wheel throws off, clutch fork wheel does not rotate with main shaft and is in free state, like this, just can arbitrarily turn round.When car need carry out straight line when moving ahead, release handle, rely on the screen resilience of spring 15 make driving wheel 11 slippage to the right and with fixed wheel 10 interlocks, clutch fork wheel rotates with main shaft, car moves ahead as straight line.Solid welding has bearing seat 16 under the car body, and the bearing 17 on the main shaft is loaded in the bearing seat.
The about throttle 31 of fire an engine is loaded on the vehicle frame, for the usefulness of starting and flame-out shutdown.
The length of every bifurcated 3 can be adjusted according to the size of stair 32, and this is undertaken by Retractive leg.The structure of Retractive leg is referring to Fig. 5.Furcated end has screw rod 33, is screwed in the nut of annotating in supporting leg 34 35, and supporting leg is made with whippy rubber, and nut is made with duroplasts, in the supporting leg nut upper hole spring 36 is arranged.Can play locking effect to bolt and nut.There is packing ring 37 the spring upper surface.Tighten supporting leg to shorten bifurcated length, return loose supporting leg with elongation bifurcated length.
A wheel 30 is arranged at the vehicle frame bottom, as places the level land, in order to keep car body and contained object steady, can go back to shown in Fig. 1 dotted line propping up wheel.As above downstairs or climbing, can change and go up and frame props up on vehicle frame shown in Fig. 1 solid line propping up wheel.
Upstairs or during climbing, vehicle frame is towards the place ahead, the people in the other walking of car to lead the neck car or climbing upstairs.Downstairs or during descending, the driving engine that can stop utilizes car weight power descending, vehicle frame is positioned at the rear, and the people stands in behind the car to control.
When needing the object that carrying weight is heavier or volume is bigger, fork wheel of the present utility model can be increased to three or four, specifically arrange referring to Fig. 4.Solid line is partly represented four-wheeled, dotted line as shown left represented be in the three-wheel vehicle one wheel 12.Illustrating right-hand two-wheeled is driving wheel, and diagram left one is taken turns or two-wheeled 27 is flower wheel.
The utility model contrast prior art has following advantage: but loading or Manned carry out motor-driven upstairs and manually downstairs; Can carry out the field climbing; Turn round Convenient; Flexible operation.
