Description

A planetary wheel stair truck

technical field

The utility model relates to a tool for climbing stairs, in particular to a planetary wheel staircase truck.

Background technique

At present, many office buildings and residential buildings below six floors are not equipped with elevators. The transportation of goods on these floors is basically carried by manpower. When encountering heavy office supplies, furniture, and daily necessities, human transportation is not only time-consuming, labor-intensive and Bring unsafe factors to the transportation process. Therefore, people urgently need a kind of cargo truck that can climb stairs to replace manpower carrying. Most of the current stair delivery tools adopt the mode of manpower pushing and pulling, and at the same time, the existing stair delivery trucks fail to solve the problems of balance and steering in the process of advancing.

Contents of the invention

In order to solve the problems of balance and steering in the existing stair freight equipment, the utility model provides a planetary wheel stair freight trolley. During the process of carrying cargo and climbing stairs, the height of the trolley can be adjusted by adjusting the height of the carriage and the frame. Balance, the car can turn freely by adjusting the universal wheel.

The technical solution adopted by the utility model to solve the technical problem is: a planetary wheel stair truck, which is composed of a carriage, a transmission device, a planetary wheel, a vehicle frame, and a handrail. The transmission device includes a reduction motor, a clutch, and a gear transmission group. The two sides of the transmission shaft are connected with the planetary wheels arranged on both sides of the vehicle frame, one side of the carriage is hingedly connected with the vehicle frame, and the vehicle frame is also equipped with a steering device and an electric push rod. The steering device includes a rotating disc, a screw, and a universal wheel. The lower end of the screw is provided with a universal wheel, and the upper end is provided with a rotating disc. The electric push rods are installed in pairs on the side of the vehicle frame close to the steering device.

As a preferred technical solution of the utility model, the upper end of the electric push rod is hingedly connected to the bottom of the compartment.

The beneficial effects of the utility model are: the planetary wheel stair truck has a simple structure, is economical and practical, does not need to consume too much manpower in the process of climbing stairs with loads, and can adjust the center of gravity of the vehicle during the process of climbing and descending. The car body remains balanced, and free steering can be achieved with a small space between landings.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

As shown in Fig. 1, Fig. 2 and Fig. 3, a planetary wheel stair truck is composed of a compartment 1, a transmission device 2, a planetary wheel 3, a vehicle frame 4, and a handrail 5. The transmission device 2 includes a reduction motor 201, The clutch 202, the gear transmission group 203 and the transmission shaft 204, the reduction motor 201 is connected with the clutch 202, and the torque is transmitted to the transmission shaft 204 through the gear transmission group 203, and the two sides of the transmission shaft 204 are arranged on both sides of the vehicle frame 4 The planetary wheels 3 are connected, one side of the compartment 1 is hingedly connected with the vehicle frame 4, a pair of handrails 5 are installed behind the vehicle frame 4, and the vehicle frame 4 is also provided with a steering device 6 and an electric push rod 7, The upper end of the electric push rod 7 is hingedly connected with the bottom of the carriage 1, the steering device 6 includes a rotating disc 601, a screw 602, and a universal wheel 603, the lower end of the screw 602 is provided with a universal wheel 603, and the upper end is provided with a rotating circle. The disc 601 can adjust the center of gravity and direction of the car body through the steering device 6, so that the car body can be kept in balance during the forward process. The electric push rods 7 are installed in pairs on the vehicle frame near the side of the steering device 6.

Its specific implementation method is: in the process of climbing stairs, the transmission shaft 204 in the transmission device 2 drives the rotation of the planetary wheel 3, and the truck realizes the function of climbing stairs. Start the electric push rod 7 to jack up the compartment 1. At this time, the center of gravity of the vehicle body moves forward, so that the vehicle body returns to a balanced state; during the process of going downstairs, the center of gravity of the vehicle body will tilt forward. The height is reduced, so that the center of gravity of the vehicle moves backward. When turning, hold the handrail 5 with both hands, and adjust the direction through the universal wheel 603, so that it does not need to consume too much manpower in the process of climbing stairs with loads. In the process of going downstairs, the center of gravity of the car can be adjusted to keep the car body balanced, and the free steering function can be realized with a small space between the stair platforms.
