Pedal steering apparatus, steering method of conveyor and conveyor with low structure height

Abstract

The invention provides a conveyor with low structural height, comprising a framework 14, a continuous treadle conveying channel, a first side driving medium 1, a second side driving medium 2, a first driving part 6a and a second side driving part 6b, wherein, the continuous treadle conveying channel is arranged inside the framework 14 and consists of a plurality of treadles 7; the front part and the back part of a first side of the treadle 7 are provided with a first side back wheel 3a and a first side front wheel 4a respectively; the front part and the back part of a second side of the treadle7 are provided with a second side back wheel 3b and a second side front wheel 4b respectively; the first side driving medium 1 and the second side driving medium 2 are arranged on the first side and the second side of the treadle 7 in parallel, and are used for driving the treadle 7 to move; the first side driving part 6a and the second side driving part 6b are used for driving the first side driving medium 1 and the second side driving medium 2 respectively; and a first side driving part rotation axis 15a and a second side driving part rotation axis 15b are alternately arranged front and back along the moving direction of the treadles 7 which are about to turn around. The conveyor can be directly arranged on a substrate, such as a floor; moreover, when the position of the conveyor or an equality unit thereof needs to be moved, or the conveyor or the equality unit thereof is reinstalled, the prior conveyor can be quickly moved from one place to another.

Description

technical field [0001] The invention relates to a pedal steering device for a conveyor and its equivalent, a method for changing the moving direction of the pedal at the end of the conveyor mechanism, and also to a conveyor with a low construction height and its equivalent. Background technique [0002] Like moving walkways or escalators, a conveyor is a conveying device used to move people or carry goods. Similar to the current existing moving walkways, it always transports people or goods from one place to another at a small inclination angle (usually 0-12°). A generally flat and uniform linear carrying path formed by multiple treads, similar to a belt conveyor. [0003] In the prior art, the conveyor has a relatively large driving device and end pedal steering device, and pits about 1 meter deep and several meters long must be provided at both ends of the conveyor to accommodate the installation of the driving device and The frame structure of the end pedal steering dev...

Problems solved by technology

[0006] However, at the end areas of the tracks on both sides of the pedals, multiple openings must be provided on the tracks for the fasteners and the rear wheels to pass through, which affects the smoothness of the front wheels and causes phenomena such as pedal vibration. If the opening design is not Reasonable, there will also be cases where only two rear wheels support the pedals in some sections

In addition, according to the limiting formula for the distance between the supporting element and the transmission part disclosed in the patent: L=1 / 2*(p-π / 2*r), compared with the transmission part (such as a drive chain or a toothed belt) Correspondingly, p is the distance between the fasteners of two pedals arranged continuously, that is, the pedal pitch, which is proportional to the pitch of the transmission member, and r is the radius of the driving member (such as a drive sprocket or pulley), It is also proportional to the pitch of the transmission part. Therefore, L is proportional to the pitch of the transmission part. When the transmission part is extended due to aging or wear, theoretically the corresponding L will become larger, and L is the wheelbase of the front and rear rollers of the pedal. Half of , which is the static parameter of the pedal, is determined at the time of manufacture, which produces the phenomenon that the pedal turns uncoordinated at the end
