Pedal supporting device of rotary drilling rig

Abstract

The invention relates to a pedal supporting device of a rotary drilling rig. The pedal supporting device comprises a pedal, a fixing plate, a clamping column, an elastic clamp, a first hinge, a movable support, a second hinge and a limiting groove. One side plate face of the fixing plate is fixedly arranged on the side face of a cab platform, the pedal is movably connected with the upper end of the fixing plate through a first hinge, the upper portion of the clamping column is fixedly connected with the fixing plate, the elastic clamp is directly or indirectly arranged below the pedal plate, and the elastic clamp is a U-shaped clamping groove made of elastic materials; when the pedal and the fixing plate are in a folded state through the first hinge, the elastic clamp is clamped on the clamping column; and the movable support is movably connected with the edge of one side of the fixing plate through a second hinge, and the limiting groove is fixedly formed below the pedal and used for limiting the rotating position of the movable support. The pedal supporting device is simple in structure and convenient to disassemble and assemble, and has the advantages of being easy to operate and use, safe, stable and reliable.

Description

technical field [0001] The invention belongs to the technical field of rotary drilling rigs for piling machinery, and in particular relates to a pedal support device for rotary drilling rigs. Background technique [0002] Conventional crawler-type rotary drilling rigs are equipped with a cab. When entering the cab, the operator usually steps on the crawler first, and then climbs up the cab. During debugging, the operator operates the driving rig, and the technician can only stand on the moving crawler to observe. In the case of the central control screen, there is a great security risk. The traditional method of setting the pedals for drilling rigs is to directly fix the pedals to the vertical plate on the outside of the platform below the cab by welding or bolt fastening, but if the pedals set in this way are too long , the outer edge of the pedal will exceed the outer edge of the track, resulting in an over-width of the vehicle, increasing the transportation cost or reduc...
