Technical Field

The utility model relates to a pavement footboard, more specifically say, relate to a pavement footboard, have unsettled pavement dig rig soon.

Background

The channels on the two sides of the platform are commonly applied to large-scale engineering machinery at present, for example, on a large-scale rotary drilling rig, suspended walkways on the two sides can bring much convenience, more and more operators hope that the walkways can be configured on the rotary drilling rig, and the walkways are generally configured in front of and at the side of a cab or at one side and two sides of a body of the rotary drilling rig. The platform walkway mainly has the advantages that the walkway is placed in front of the cab, a manipulator can stand on the walkway to observe the use condition in front of the movable arm, the glass can be easily cleaned, the walkway is placed on the side of the cab, and the manipulator can conveniently enter and exit the cab when the rotary drill rotates 90 degrees. The walkways are placed on two sides of the platform, so that a manipulator and workers can walk to the machine bodies on two sides of the rotary drilling rig through the walkways under the condition that the rotary drilling rig rotates at any rotation angle, and meanwhile, the crawler full of soil is prevented from being stepped on at night.

The existing scheme of the suspended walkway of the platform is that a single side of the suspended walkway is fixed on the platform. Therefore, the phenomenon of super-width can occur during the transportation of the engineering machinery, and the suspended walkway needs to be detached before the transportation and then installed after the transportation to the destination. Because unsettled pavement is all made by steel generally, and weight is great, and the mounted position is higher, consequently unsettled pavement's dismouting is comparatively difficult, generally needs two people cooperation dismantlements, wastes time and energy, and the pavement under the dismantlement simultaneously is easy to be lacked in the transportation.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that current unsettled pavement causes machinery super wide and need dismantle the problem of transportation, and provides a pavement footboard, has unsettled pavement dig the rig soon, and this machinery need not to dismantle unsettled pavement when the transportation, only needs folding pavement footboard can avoid the super wide problem of machinery transportation.

The utility model discloses a realize that the technical scheme of its purpose is like: the walkway pedal mainly comprises a pedal and a support, and is characterized in that the pedal mainly comprises arm beams which are positioned at two ends and are parallel to each other and a flat plate fixedly connected with the two arm beams, the end part of each arm beam is rotatably connected with the support through a pin shaft, and the support is provided with a downward rotation preventing support mechanism for supporting the arm beams in a horizontal state.

In the walkway pedal, the support comprises a fixed mounting plate and two hinged plates which are vertically and fixedly connected with the fixed mounting plate, the end part of the arm beam is positioned between the two hinged plates, and hinged holes for the pin shaft to pass through are arranged on the hinged plates and the arm beam.

In the above walkway step, one of the hinged plates is provided with a bending support plate which is bent towards the other hinged plate to form the downward rotation prevention support mechanism, and the bending support plate is positioned obliquely below the hinge hole on the hinge lug plate.

In the walkway pedal, the hinge hole on the arm beam is a long hole, and the length direction of the long hole is consistent with that of the arm beam.

In the walkway pedal, the distance between the bending support plate and the fixed mounting plate is slightly larger than the width of the arm beam in the vertical direction at the position where the long hole is arranged.

In the above-mentioned pavement footboard, be provided with on the support be used for with vertical state the spacing vertical stopper of footboard of arm roof beam contact of footboard, the vertical stopper of footboard is to the protrusion of footboard direction fixed mounting plate surface.

The utility model discloses a realize that the technical scheme of its purpose is like: the rotary drilling rig with the suspended walkways is provided with the suspended walkways and is characterized in that the suspended walkways are composed of a plurality of walkway pedals, and the support is fixedly connected with a rotary drilling rig platform.

In the rotary drilling rig, the suspended walkways are arranged on the left side surface and the right side surface of the rotary drilling rig platform, the left side surface and the front side surface of the cab.

Compared with the prior art, the utility model, dig the rig soon and walk the footboard when the operation and rotate to the level, make things convenient for the staff current on the pavement, when the transportation, upwards rotate the footboard and parallel with the machine side, avoid leading to the super wide problem of machine transportation because of the footboard.

Detailed Description

The following description of the embodiments refers to the accompanying drawings.

As shown in fig. 1 and fig. 2, in the rotary drilling rig of the present embodiment, suspended walkways 3 are installed on left and right side surfaces of the upper rotating platform 1 and left and front side surfaces of the cab 2. The suspended walkway 3 is composed of one or more walkway pedals arranged in sequence.

As shown in fig. 3, the walkway treadle 3 is mainly composed of treadles 5 and pedestals 4, the treadles 5 are mainly composed of arm beams 51 which are positioned at two ends and are parallel to each other and a flat plate 52 fixedly connected with the two arm beams 51, the end parts of the arm beams 51 are rotatably connected with the pedestals 4, and the pedestals 4 are provided with anti-rotation support mechanisms which support the arm beams 51 in a horizontal state.

As shown in fig. 4, the support 4 includes a fixed mounting plate 41, two hinge plates 43 vertically and fixedly connected to the fixed mounting plate 41, and the two hinge plates 43 are provided with coaxial hinge holes 45. One of the hinge plates is provided with a bending support plate 44 which is bent towards the other hinge plate to form a downward rotation prevention support mechanism, and the bending support plate 44 is positioned obliquely below a hinge hole 45 on the hinge lug plate. The support 4 is provided with a pedal vertical limiting block 46, and the pedal vertical limiting block 46 protrudes towards the pedal direction to fix the surface of the mounting plate 41.

As shown in fig. 5, the arm beam 51 and the flat plate 52 of the step 5 are welded and fixed, and a hinge hole 53 is provided at an end of the arm beam 51, and the hinge hole 53 is a long hole having the same longitudinal direction as the arm beam 51.

As shown in fig. 3. The end of the arm beam 51 of the pedal 3 is positioned between the two hinged plates 41 of the support 4, the pin shaft 6 passes through the hinged hole 45 of the hinged plate 43 and the hinged hole 53 of the arm beam 51, and the pin shaft 6 is positioned by a cotter pin.

As shown in fig. 6, when the rotary drilling rig is not in transportation, if a person wants to walk on the suspended walkway, the pedals need to be laid flat. In the pedal in a flat state, the end of the arm beam 51 is in contact with the fixed mounting plate 41 for a limit, and the bent support plate 44 supports the arm beam 51 so that the arm beam 51 is in a cantilever structure in a horizontal state. When the suspended pedal needs to be folded up during transportation, the pedal 3 can be rotated upwards, when the arm beam 51 rotates to the vertical position, the pedal moves downwards, the end part of the arm beam 51 is inserted between the bent support plate 44 and the fixed mounting plate 41, the arm beam 51 is vertically fixed, and the pedal is prevented from being automatically turned outwards and laid flat. The vertical stopper 46 of footboard on support 4 also contacts with arm roof beam 51, carries out spacing fixed to the arm roof beam, prevents that the footboard from rocking.

The utility model discloses a pavement footboard rotates to the level, makes things convenient for the staff current on the pavement, when the transportation, upwards rotates the footboard and parallels with the machine side, avoids leading to the super wide problem of machine transportation because of the footboard.
