The technical field is as follows:

the invention relates to the technical field of underground personnel transportation, in particular to a pedal step and a pedal type walking aid.

Background art:

in the underground coal mine, inclined roadways widely exist, and underground workers often have great labor when walking in the inclined roadways. At present, an underground inclined roadway mainly adopts an overhead manned device to convey personnel, and the safety of the overhead manned device is relatively low, so that potential safety hazards of insecure hanging of a monkey vehicle, collision of the monkey vehicle with personnel and the like exist; in addition, the person gets on or off the monkey car in operation also very inconvenient, especially when the person carries knapsack or instrument, inconvenient reuse both hands go to hang and take off the monkey car.

The pedal type elevator is a tool which is frequently used in life of people for going upstairs and downstairs, and is labor-saving and convenient to use, however, because the underground inclined roadway is low in height, and the pedal type elevator needs a large installation space, the traditional pedal type elevator cannot be applied to the underground inclined roadway of a coal mine.

The invention content is as follows:

in order to solve the technical problems, the invention provides a pedal step and a pedal type walking aid, which have small required installation space, can realize the installation in an underground inclined roadway, and can convey personnel in the mine inclined roadway in a labor-saving, convenient and safe manner.

The invention is realized by the following technical scheme:

the utility model provides a pedal step, includes the step body, characterized by, the step body is including being no less than 2 components of a whole that can function independently parts in the front and back direction, the components of a whole that can function independently part includes the footboard and fixes the connecting plate at footboard both ends, it has 2 mounting holes to open respectively on the connecting plate, and the footboard level of all components of a whole that can function independently parts sets up and highly the same, and the contained angle of the line of each mounting hole and horizontal plane equals with the installation angle of step body.

In another aspect of the invention, the bottom of the front end and the bottom of the rear end of the connecting plate are respectively provided with a notch.

In another aspect of the present invention, a kick plate extends downward from a rear end of the step of the rearmost split portion.

In another aspect of the present invention, risers extend downward from the front end and the rear end of the pedal, respectively.

In another aspect of the invention, the step body comprises 2 split parts arranged in tandem.

A pedal type walking aid, which is characterized by comprising a preset number of pedal steps as claimed in claim 1 and a chain conveying system for driving the pedal steps to rotate around, wherein the pedal steps are arranged between two chains of the chain conveying system, and mounting holes of the pedal steps are inserted on pin shafts of the chains.

In another aspect of the present invention, each pin passes through 2 mounting holes corresponding to both ends of the step and is shared by two chains of the chain conveyor system.

In another aspect of the present invention, the chain conveying system includes an upper mounting frame and a lower mounting frame, the upper mounting frame and the lower mounting frame are respectively rotatably mounted with a driving shaft, the driving shaft is respectively provided with 2 driving sprockets, a roller chain is wound between the driving sprockets on the same side of the 2 driving shafts, and the chain conveying system further includes 2 sets of power devices respectively driving the 2 driving shafts to rotate.

In another aspect of the invention, side guard plates are fixedly connected between the upper mounting frame and the lower mounting frame, the side guard plates are respectively arranged at the outer sides of the 2 roller chains, and supporting plates are fixed at the inner sides of the side guard plates and are supported at the bottoms of the rollers of the upper-layer chains.

In another aspect of the invention, the handrail is arranged on one side or two sides of the foot step, and the handrail is provided with a handrail belt which runs synchronously with the foot step.

The invention has the beneficial effects that: the pedal step and the pedal type walking aid have the advantages that on the premise that the length of the pedal step can meet the requirement of a person for treading, the required installation space is small, and the person can be conveyed in a mine inclined roadway in a labor-saving, convenient and safe manner.
