Abstract

The invention provides a rail transport vehicle for stairs, which mainly includes a rail 1, a toothed wheel 2, a power unit 3, a vehicle frame 4, a height adjustment device 5, a bearing frame 6, fixing bolts 7 and bearing rollers 8. The track is hoisted on the lower slope surface of the stair floor by fixing bolts 7, the power unit 3 drives the toothed wheel 2 to run on the track, the bearing frame 6 is installed on the vehicle frame 4 through the height adjustment device 5, and the vehicle frame is equipped with load-bearing rollers 8, All loads on the trolley are applied to the bearing surface of the track via the bearing rollers. The height adjusting device is used for adjusting the height of the bearing frame. Except for the track, other parts of the entire transporter can be easily removed and placed elsewhere when not in use. The invention has the advantages of simple structure, small occupied space, convenient installation, low cost and convenient use.

Description

Rail trolleys for stairs

technical field

The invention belongs to the technical field of transportation, and in particular relates to a rail-type transport vehicle used for stairs.

Background technique

Our country will enter the age of aging. There are no elevators installed in the existing residential buildings with less than seven floors. It is very inconvenient for the elderly to go up and down the stairs. Among the technical solutions that have been proposed so far, some use a crane with pulleys installed on the roof, some use an escalator on the side wall, and some use a crawler vehicle that can walk on the stairs, but due to the limited installation space, the transformation cost is high, or Factors such as inconvenience have not been well applied so far.

Contents of the invention

The invention provides a rail-type transport vehicle used for stairs. A driving mechanism is driven by a power device to walk on rails, so as to realize lifting and lowering of effective loads between floors.

The technical scheme adopted in the present invention is: design a track-type transport vehicle, which mainly includes track 1, toothed wheel 2, power unit 3, vehicle frame 4, height adjustment device 5, load-bearing frame 6, fixing bolt 7 and load-bearing roller 8 . The track is hoisted on the lower slope surface of the stair floor through the fixing bolt 7, and the corners of each floor adopt arc track transition, the power device 3 drives the toothed wheel 2 to run on the track, and the bearing frame 6 is installed on the frame through the height adjustment device 5 4, the frame is equipped with load-bearing rollers 8, and all loads are pressed on the bearing surface of the track through the load-bearing frame, height adjustment device, frame and load-bearing rollers. The height adjustment device is used to adjust the height of the load-bearing frame, except that the track is fixed on the stairs. On the road, other parts of the entire transport vehicle can be removed and placed elsewhere when not in use, so that other people can go up and down the stairs normally.

The invention has the advantages of simple structure, small occupied space, convenient installation, low cost and convenient use.

Among the figure: 1. track, 2. toothed wheel, 3. power unit, 4. vehicle frame, 5. height adjustment device, 6. bearing frame, 7. fixing bolt, 8. load-bearing roller.

Detailed ways

The technical scheme adopted in the present invention will be further described below in conjunction with specific embodiments. With reference to the accompanying drawings, the rail transport vehicle mainly includes a track 1, a toothed wheel 2, a power unit 3, a vehicle frame 4, a height adjustment device 5, a load bearing Frame 6, fixing bolt 7 and bearing roller 8. The track is hoisted on the lower slope surface of the stair floor by fixing bolts 7, and the corners of each floor adopt arc-shaped track transition, and the bearing surface of the track is provided with windows at equal distances along the length direction. Corresponding to the teeth of the toothed wheel, the toothed wheel can mesh with the window hole and roll. The power unit 3 is fixed on the vehicle frame 4, and the power unit transmits the driving force to the toothed wheel through the transmission shaft. When the toothed wheel rolls, the vehicle frame will move along the length direction of the track. Two carrying rollers 8 are connected with the vehicle frame by the support, the support can rotate relative to the vehicle frame, the carrying rollers can roll on the bearing surface of the track, and all the loads on the vehicle frame are borne by the carrying rollers. The bearing frame 6 is installed on the vehicle frame through the height adjusting device 5. The bearing frame can be made into different shapes according to the loading objects. The height of the bearing frame from the ground can be adjusted through the height adjusting device. Just can realize the up and down operation of transport vehicle, the energy of power unit and height adjusting device is provided by accumulator. Except the track, all other components can be removed from the track as a whole, and can be placed elsewhere when not in use, without affecting other people's normal up and down stairs.
