Embodiment 1

[0022] Such as Figure 1~4 Shown, a claw wheel device for climbing stairs, it includes:

[0023] The claw wheel 4, the claw wheel 4 includes a wheel 3 and a claw 10, the wheel 3 is installed on the wheel shaft 8, and the wheel 3 is provided with one-to-one correspondence with the claw 10 and external The corresponding claw 10 can be accommodated in the claw groove under the action force, and the claw 10 is hinged in the corresponding claw groove through the claw shaft, and the gap between the claw 10 and the wheel 3 The claw 10 is set to act on the claw 10 and can make the claw 10 swing until the outer end of the claw 10 protrudes from the wheel disk 3. An open holding structure is also provided between the claw 10 and the wheel disk 3. The claw 10 swings until the outer end of the claw 10 protrudes from the wheel 3 and is located at the uppermost position to limit the limit structure of the claw 10 to continue to swing; the limit structure can ensure the opening angle of the...

Embodiment 2

[0032] Such as Figure 1~4 Shown, a kind of power-assisted luggage cart, it comprises vehicle frame, load rack 9, wheel axle 8, wheel 5 and stair climbing claw wheel device, and described load frame 9 is hinged on the vehicle frame, and described wheel axle 8 is rotatably supported on the vehicle frame, and the wheel disc 3 in the claw wheel device for climbing stairs is mounted on the wheel shaft 8, and the wheel 5 is rotatably mounted on the wheel shaft 8; wherein, the load The object rack 14 is put down when loaded, and put away when not loaded. The wheels 5 are provided with two, and the claw wheels 4 are also provided with two, which are respectively located in the inner side of the corresponding wheels 5 .

[0033] Such as figure 1 As shown, the vehicle frame includes a main frame 2 and a subframe 1, and the subframe 1 is movably connected to the main frame 2 so that the vehicle can be lengthened or shortened by moving the subframe 1. the length of the shelf.

Abstract

The invention discloses a clamping claw wheel device for climbing stairs and an assistance luggage car applying the same. The clamping claw wheel device for climbing the stairs comprises clamping claw wheels and a wheel plate rotating driving device. Each clamping claw wheel comprises a wheel plate and clamping claws. The wheel plates are mounted on a wheel shaft; clamping claw grooves which are in one-to-one correspondence with the clamping claws and can contain the corresponding clamping claws under the external acting force are formed in the wheel plates; the clamping claws are hinged in the corresponding clamping claw grooves; opening and maintaining structures which act on the clamping claws and enable the clamping claws to swing to the protruding wheel plates of the outer ends of the clamping claws are arranged between the clamping claws and the wheel plates; and limiting structures are further arranged between the clamping claws and the wheel plates, wherein the limiting structures are used for limiting the clamping claws to continue swinging when the clamping claws swing to the protruding wheel plates of the outer ends of the clamping claws and located in the maximum upper limiting positions. The wheel plate rotating driving device is connected with the wheel shaft to drive the wheel shaft to rotate to drive the wheel plates to rotate. The clamping claw wheel device enables the luggage car to climb the stairs up and down, so that manpower consumption is relieved.

Description

technical field [0001] The invention relates to a claw wheel device for climbing stairs and a power-assisted luggage cart using the same. Background technique [0002] At present, with the rapid development of computer and Internet technology, the e-commerce industry has sprung up like mushrooms after rain. While promoting the rapid development of the logistics industry, the heavy delivery of express goods has greatly increased the labor intensity of couriers. And couriers inevitably need to go up and down stairs when delivering goods. At present, old-fashioned buildings with five or six floors and no elevators are still common. Holding a lot of heavy goods up and down the stairs has certain safety hazards for couriers and the goods they carry. Therefore, it is very necessary and promising to design a kind of light trolley that can carry goods on flat ground and can climb stairs to go up and down. Contents of the invention [0003] The technical problem to be solved by ...
