Specific embodiment
In order that present disclosure is easier to be clearly understood, it is right below according to specific embodiment and with reference to accompanying drawing
The present invention is described in further detail.
Embodiment one
As shown in figures 1-4, one kind climbs building claw wheel apparatus, and it includes：
Claw wheel 4, the claw wheel 4 includes wheel disc 3 and claw 10, and the wheel disc 3 is arranged on axletree 8, the wheel
The claw groove for being corresponded to claw 10 and corresponding claw 10 being contained under applied external force in it is provided with disk 3,
The claw 10 is hinged in corresponding claw groove by claw axle, is set between the claw 10 and the wheel disc 3 and acted on
On claw 10 and can make what claw 10 was rocked to the outer end protrusion wheel disc 3 of claw 10 to open holding structure, the claw 10 with
It is additionally provided between the wheel disc 3 when claw 10 is rocked to the outer end protrusion wheel disc 3 of claw 10 and is located at most upper limit position
Limit the position limiting structure that claw 10 continues to swing；Position limiting structure can with ensure claw 10 opening angle and keep institute it is angled
Uniformity.
Wheel disk drivingly rotating device, the wheel disk drivingly rotating device is connected with axletree 8, so that the wheel disc spins are driven
Dynamic device drives the axletree 8 to rotate, so as to drive the wheel disc 3 to rotate.
It can be various structures to open holding structure, and two kinds of structure is introduced in the present embodiment：The first is：It is described
Holding structure is opened for spring, one end of the spring is connected on wheel disc 3, the other end of the spring and corresponding claw 10
Outer end is connected, so that spring provides a support force to the outer end of claw 10；It is for second：The holding structure of opening is for bullet
Spring, one end of the spring is connected on wheel disc 3, and the other end of the spring is connected with the inner end of corresponding claw 10, so as to
Spring provides a pulling force to the inner end of claw 10.
As shown in Figure 3,4, the position limiting structure includes the confined planes 101 being arranged on the inner end of claw 10 and is arranged on
Form on the wall of claw groove and can be abutted with confined planes 101 the cooperation confined planes 102 for coordinating.When claw 10 is rocked to claw 10
Outer end protrusion wheel disc 3 and when being located at most upper limit position, the confined planes 101 coordinate together with confined planes 102 abut with described,
The claw 10 can not continue protruding.
The claw 10 is provided with least two, and along the circumferential uniform of wheel disc 3, accordingly, the claw groove is set
Have at least two；In the present embodiment, claw 10 is provided with three, but not limited to this, and claw 10 can also be symmetrical arranged two
It is individual.
As shown in figure 1, the wheel disk drivingly rotating device includes motor 7 and reductor 6, the motor 7 and the deceleration
The input shaft drive connection of machine 6, the output shaft of the reductor 6 is connected with the axletree 8.Reductor 6 uses worm and gear
Decelerator 6, it has auto-lock function, to prevent car slipping during accident, and then improves security performance of the car in stair climbing；
Motor in the present embodiment uses direct current generator, and has battery to provide electric power, and motor 7 and reductor 6 are combined into one, its bottom
Seat is arranged on main car frame 2, the output shaft driving moment axle 8 of reductor 6, and controlling switch is arranged on the handle of subframe 1.
Claw 10 in the present embodiment can bear the tangential force of wheel disc 3, and in stair climbing, claw 10 blocks the upper of stair
Side, in the rotation process of wheel disc 3 when the radial load suffered by claw 10 be more than tangential force when, claw 10 is pressed into corresponding claw
In groove, when radial load is less than tangential force, claw 10 opens automatically under spring force.
When people runs into stair with the luggage truck loading, the luggage truck is drawn and leans on stair, switched on power, motor 7 is rotated, car
Wheel shaft 8 is rotated, and drives claw wheel 4 to be rotated to the direction of stair, and claw 10 blocks the top edge for riding over stair, drives vehicle to climb up one
Individual ladder, then, people continues to draw step on the lower, claw wheel 4 to be rotated further in the car, and another claw 10 blocks ladder top
Edge, completes cat ladder action, such continuous action, only to having climbed whole stair；When level land travels, without the grade of claw wheel 4, mechanism is auxiliary
Motion is helped, as long as claw 10 is adjusted into appropriate location, makes claw 10 not in contact with the ground during luggage truck is towed, cut-out electricity
Source, is dragged by manpower.Maximum of the present invention can carrying 60kg goods stair activities.
Embodiment two
As shown in figures 1-4, a kind of power-assisted luggage truck, it includes vehicle frame, luggage carrier 9, axletree 8, wheel 5 and climbs building use
Claw wheel apparatus, the luggage carrier 9 is hinged on vehicle frame, and the axletree 8 can be rotated to support on vehicle frame, described to climb building use
Wheel disc 3 in claw wheel apparatus is arranged on axletree 8, and the wheel 5 is rotatably installed on axletree 8；Wherein, it is described
Put down during 14 loading of luggage carrier, packed up during not loading, the wheel 5 is provided with two, and the claw wheel 4 is also equipped with two,
Respectively positioned at the inner side of corresponding wheel 5.
As shown in figure 1, the vehicle frame includes main car frame 2 and subframe 1, the subframe 1 is movably connected in the main car
On frame 2, will pass through the action subframe 1, the length of vehicle frame is elongated or shortened.
The subframe 1 is slideably sleeved on the main car frame 2；Or the subframe 1 is hinged on the master
On vehicle frame 2.
The claw wheel 4 and wheel 5 are applied in combination, rolling when can respectively realize that the power-assisted of stair activity is pacifically towed
It is dynamic.The diameter of wheel of the invention 5 is the minimum value design of the maximum and span with reference to stairway step height in GB, card
The diameter of ratchet wheel disk 3 is slightly less than the diameter of wheel 5, has so both avoided the interference when level land tows, and can allow stair climbing again
When wheel 5 contact stair horizontal plane quickly, subtract jolting for luggage truck.
When that need not use, auxiliary frame 1 being inserted (or folding) in main car frame 2 (or side), by luggage carrier 9
It is folded on the side of main car frame 2 so that vehicle profile is substantially reduced, is convenient for carrying, deposits；By auxiliary frame 1 and loading when using
Frame 9 launches, and during the fortune thing of level land, because the diameter of wheel disc 3 is smaller than wheel 5, claw wheel 4 will not touch ground, now lean on completely
Manpower is pulled；When needing power-assisted stair activity, luggage truck is drawn and leans on stair, be then turn on power supply, motor 7 runs, drive claw
Wheel 4 is rotated.Claw wheel 4 turns to certain angle, two one pair of which claws 3 of claw wheel 4 turning simultaneously with stairway step
Contact, claw wheel 4 is rotated further offer torque and lifts luggage truck, realizes that stairs-mover climbs up one-level step or decline one-level with this
Step, needs the balance of people's auxiliary building climbing car during this.
This invention provides power-assisted when can be gone downstairs on carrying goods, greatly mitigates the physical demands carried during compared with parcel,
People is avoided not see the security incident of stairway step generation because sight line is blocked when larger goods stair activity is carried, effectively
Ensure the safety of people and goods.
Particular embodiments described above, pair present invention solves the technical problem that, technical scheme and beneficial effect carry out
Further describe, should be understood that and the foregoing is only specific embodiment of the invention, be not limited to this
Invention, all any modification, equivalent substitution and improvements within the spirit and principles in the present invention, done etc., should be included in this hair
Within bright protection domain.
