Description

Stair carry special-purpose vehicle

Technical field

It the utility model is related to a kind of stair and carry special-purpose vehicle.

Background technology

When multilayer does not have the house of elevator to fit up, many household electrical appliances, such as refrigerator, washing machine, air-conditioning large piece article need It is transported to upstairs from stair, moreover, the high level of some live ladders, because elevator is smaller, many big objects can not be transported by elevator Send.

At present, in the market has the dolly for being exclusively used in stair carrying, and the China such as the U of Authorization Notice No. CN 202272025 is real A kind of caterpillar carrying vehicle for stairs is disclosed with new patent, its overall structure is L-type, and shoe is employed below horizontal shelf Band type structure, it is convenient to be walked on stair, still, when going upstairs step, then need to lift the front end of dolly, moreover, working as First floor ladder is gone up and has needed during another floor, it is necessary to dolly has been turned to, because the space of two staircases is smaller, and if removed Fortune is that the big object such as refrigerator, cabinet air-conditioner is difficult then to be turned in narrow space.

Also a kind of carrier, structure are also L-type, and two roller groups, each roller group are set in the bottom of vertical supporting plate It is made up of three rollers, this structure needs to pull at dolly when going upstairs, and three rollers upset of roller group is by occlusion Power is upstairs, this not only laborious, and transport object jolt it is more serious.

Utility model content

In order to overcome above-mentioned problems of the prior art, the utility model offer is a kind of to be facilitated upstairs, is transported steadily, And the stair that can be flexibly turned in narrow and small stairway spaces carry special-purpose vehicle.

In order to solve the above problems, the utility model uses following technical scheme：A kind of stair carry special-purpose vehicle, its feature It is：It includes L-type vehicle frame, and the bottom of the horizontal shelf of the L-type vehicle frame sets crawler wheel, the L-type vehicle frame it is vertical The bottom of supporting plate sets roller, in the junction of the horizontal shelf and vertical supporting plate, positioned at the crawler wheel and roller it Between be provided with from the arc-shaped transition area of the bottom of the gradual way roller in the end of crawler wheel extension；

Drawstring is connected with the front end of the horizontal shelf；And the front end of horizontal shelf is provided with handle.

Further, the arc-shaped transition area includes arc and connects the connecting pole of arc and L-type vehicle frame, the arc The end of shape plate is located at below the central point of the roller, and above the bottommost of the roller.

Further, there are multiple engaging lugs for connecting binding ropes in the both sides spaced set of the horizontal shelf.

Further, horizontal shelf front end bottom surface is provided with the box for placing the drawstring and binding rope Body.

Preferably, the roller is universal wheel.

The beneficial effects of the utility model are：It sets crawler wheel in horizontal shelf bottom, realizes on step It is steady to transport, roller is set in vertical supporting plate bottom, realizes and is flexibly turned in small space, crawler wheel and roller it Between arc-shaped transition area is set, ensure that smoothly transition when moving towards horizontal plane from step, it is not necessary to firmly pull dolly, compare province Power.Combined using drawstring and handle, the drawstring when step pulls up dolly, can not have to bend over, worker can find one and relax Suitable posture of pulling a cart, handle is used when turning to, can flexibly control steering.

In figure, L-type vehicle frame 1, horizontal shelf 11, engaging lug 111, vertical supporting plate 12, handle 13, reinforcement 14, crawler type Wheel 2, roller 3, arc-shaped transition area 4, arc 41, connecting pole 42, drawstring 5, box body 6.

Embodiment

Specific embodiment of the utility model is described in detail with reference to Fig. 1 to Fig. 4：

It should be noted that Fig. 1 to Fig. 4 is schematic diagram, its crawler wheel and roller are only schematic diagram, in order to Illustrate its position, their detailed structures are prior art with the mode of being fixedly connected, and therefore, are not drawn in detail in accompanying drawing.

The utility model includes L-type vehicle frame 1, and L-type vehicle frame 1 includes horizontal shelf 11 and vertical supporting plate 12, in horizontal shelf 11 and vertical supporting plate 12 on be provided with reinforcement 14, shown in Fig. 1 simply level support class 11 on be provided with reinforcement 14.It is described The bottom of the horizontal shelf 11 of L-type vehicle frame sets crawler wheel 2, and the bottom of the vertical supporting plate 12 of the L-type vehicle frame 1 sets roller 3, in the junction of the horizontal shelf 11 and vertical supporting plate 12, it is provided between the crawler wheel 2 and roller 3 from shoe The arc-shaped transition area 4 of the bottom extension of the gradual way roller 3 in end of belt wheel 2.As shown in Fig. 2 the arc-shaped transition area 4 includes Arc 41 and the connecting pole 42 of connection arc 41 and L-type vehicle frame 1, arc 41 are symmetrical set two.Arc 41 End be located at below the central point of roller 12, and above the bottommost of roller 12, it is preferred that the lower surface of arc 41 Apart from the bottommost of roller 12 about 2-4cm.

Roller 3 can use structure as shown in Figure 2, and two rollers are set at the both ends of an axle, set four rollings altogether Wheel, the end of arc 41 are fixed on axle.Certainly, in order to preferably flexibly turn to, the roller 3 be arranged to four it is independent Universal wheel, at this moment, the end of arc 41 are connected using connecting pole 42 with vertical supporting plate 12.
