Embodiment 1

[0026]Embodiment 1: Two-stage four-point car body (commonly known as: heavy-duty)

[0027] Its implementation is as follows: figure 1 As shown, the left front connecting frame (4) and the right front connecting frame (5) are respectively welded on the left and right sides of the front base beam (2), and the left rear connecting frame (6) and the right rear connecting frame are respectively welded on the left and right sides of the rear base beam (3). frame (7), the four connecting frames need to be higher than the upper surface of the track (such as figure 2 shown), and extend a certain distance to the left and right sides. Weld a "C" shaped track (8) on the left front connecting frame (4) and the left rear connecting frame (6) (such as figure 2 As shown), another "C" shaped track is welded on the right front connecting frame (5) and the right rear connecting frame (7), and the two "C" shaped tracks (8) are kept at an appropriate distance, and are connected to the car body...

Embodiment 2

[0031] Embodiment 2: Two-stage three-point car body (commonly known as: medium-sized)

[0032] Its implementation method is: in embodiment 2, only the structure of the armrest system and the position of the rear stage lifting system are different from embodiment 1, and the implementation methods of other systems are the same, and will not be described in detail here.

[0033] Such as Figure 9 As shown, the front end of the left longitudinal frame (50) is welded with the left front connecting frame (4), the middle part is welded with the left rear connecting frame (6), the rear end is welded with the left vertical frame (52), and the left reinforcing bracket (51) is respectively Be welded on the left longitudinal frame (50) and the left vertical frame (52), to strengthen its structural strength, the implementation mode of the right part is identical with the left side; ) and the top of the right vertical frame (55) are welded, the rear stage lifting system (59) is arranged in...

Embodiment 3

[0034] Embodiment 3: One-level two-point car body (commonly known as: light)

[0035] Its implementation is as follows: Figure 10 As shown, weld the left front connecting frame (4) and the right front connecting frame (5) on the front base beam (2), weld the left rear connecting bracket (6) and the right rear connecting bracket (7) on the rear base beam (3) , a lower cross frame (71) is welded on the left front connecting frame (4) and the right front connecting frame (5), and a lower horizontal frame is also welded on the left rear connecting bracket (6) and the right rear connecting bracket (7) (71), weld two lower longitudinal frames (70) respectively at the two ends of these two lower horizontal frames (71), and weld two lower horizontal frames ( 71), forming a shelf. Three vertical frames (72) are respectively welded at the welds of the lower vertical frame (70) on the left side and the three lower horizontal frames (71) at the rear, and an upper vertical frame (75) is...

Abstract

The invention discloses a lifting vehicle body, wheels and a crawler belt combined type stair climbing vehicle, which belongs to one of stair climbing vehicles. Due to the fact that an existing stairclimbing vehicle is small in load capacity, large in physical output of operators, not high in safety and the like. According to the technical scheme, a chassis is composed of a full-load, high-trafficability and low-abrasion crawler-type traveling device and used for traveling on stairs; a lifting system is arranged at the proper position of the vehicle body and used for lifting the vehicle bodyto achieve switching of wheels and crawler belts and assist the crawler belts to climb stairs. Trundles are mounted at the bottom end of the lifting system and used for driving on a road surface or astair platform; a goods shelf can move horizontally, the gravity center of goods is moved forwards, and the safety of the vehicle running on stairs is improved; double independent retractable safety tails are arranged at the tail of the vehicle body, so that the safety of the vehicle is further improved, and the vehicle is prevented from overturning. According to the invention, safe transportationof large-load-capacity and large-volume goods on stairs can be realized.

Description

[0001] 1. Technical field [0002] The patent of the present invention relates to a lifting car body, a wheel and crawler compound type stair climbing car, which belongs to a kind of stair climbing car. [0003] 2. Background technology [0004] Currently known stair climbers are roughly divided into unpowered and powered two categories. All unpowered stair climbing vehicles are hand trailers, which are not described here. The overall structure of the powered stair climbing car is "L" shape, and there are two casters at the bottom of the "L" shape. The position of shape "one" is the shelf for placing goods. His working method is: the operator uses the casters when pulling the vehicle on the road; when encountering the stairs, the casters are in contact with the vertical surface of the stairs. At this time, the switch of the climbing action mechanism is turned on, and the action mechanism starts to work. The operator pulls the vehicle to move along the horizontal plane of the...
