Detailed Description

Referring to fig. 1-7, a foldable walkway comprises a girder frame 1, a walkway plate 4, a cantilever beam 2 and a guardrail 3, wherein one end of the cantilever beam 2 is hinged to one side of the girder frame 1, the cantilever beam 2 can be rotatably arranged along the horizontal direction of the hinged position, the other end of the cantilever beam 2 is hinged to the guardrail 3, the walkway plate 4 is located on the cantilever beam 2, one end of the walkway plate 4 is hinged to the girder frame 1, and the walkway plate 4 can be overturned along the vertical direction of the hinged position to form a frame. When the walking board 4 works, the walking board is overturned and positioned on the cantilever beam 2, so that the bearing capacity of the walking board can be enhanced, and the strength of the walking board is ensured. When the folding device is required, the walkway plates 4 are vertically turned and folded on the main beam frame 1, and the cantilever beams 2 for supporting the walkway plates 4 can be rotated and folded in the horizontal direction to enable the guardrails 3 to be attached to one side of the main beam frame 1, so that the device can be conveniently transported in a transition way.

The walking mechanism comprises a main beam frame 1, a walking plate 4, a first pneumatic spring 5 connecting plate 1-4, a second pneumatic spring 5 connecting plate 4-1, a pneumatic spring 5, a first pneumatic spring 5, a second pneumatic spring 5, a first pneumatic spring 5 connecting plate 1-4, a second pneumatic spring 5, a first pneumatic spring 5, a second pneumatic spring 5 and a pneumatic spring 5. According to the characteristics of the industrial accessories with the functions of supporting, buffering, braking, height adjusting, angle adjusting and the like of the pneumatic spring 5, the turning operation of the walkway plate 4 by workers can be facilitated.

The main beam frame 1 is formed by welding rectangular pipes, a first hinge point 1-1 and a second hinge point 1-2 are correspondingly welded on the side edge of the main beam frame 1, a limiting hole 1-5 is formed in the first hinge point 1-1, and a walkway limiting locking plate 1-3 extends upwards from the side edge of the main beam frame 1. The limiting holes 1-5 can fix the cantilever beam 2 through bolts after the cantilever beam 2 is rotated and opened, so that the cantilever beam is prevented from automatically rotating. And the spacing locking plate plays the role of fixing the walkway plate 4 after the walkway plate 4 is turned and folded, and prevents shaking and colliding during transition transportation.

The guardrail comprises a cantilever beam 2, a hinge hole 2-4, a guardrail 3 sleeve 2-3 welded at the other end of the cantilever beam 2, a walkway fixing plate 2-2 welded at the side edge of the cantilever beam 2, and a limiting plate 2-1 welded at one side of the cantilever beam 2 close to the hinge hole 2-4, wherein the hinge hole 2-4 is formed in one end of the cantilever beam 2, the hinge hole 2-4 is connected with a first hinge point 1-1 through a pin shaft 7. The limiting plate 2-1 can prevent the cantilever beam 2 from rotating by an angle which is too large and influences the adaptive installation of the later stage of the worker. The walkway fixing plate 2-2 mainly plays a role in fixing the cantilever beam 2 and the walkway plate 4 through bolts when the walkway plate 4 is located on the cantilever beam 2.

Wherein, the bottom of the guardrail 3 is sequentially provided with a positioning ring 3-1 and a pin hole 3-2, a cotter pin 8 is arranged in the pin hole 3-2, and a distance for the sleeve 2-3 of the guardrail 3 to be inserted in a matching way is reserved between the positioning ring 3-1 and the pin hole 3-2. The positioning ring 3-1 mainly plays a role in limiting the matching insertion distance of the guardrail 3 and the sleeve ring of the guardrail 3, and the pin hole 3-2 and the split pin 8 are matched to prevent the guardrail 3 from falling off from the sleeve 2-3 of the guardrail 3.

The bottom of the walkway plate 4 is welded with a hinged circular pipe 4-2, the hinged circular pipe 4-2 is connected with a second hinged point 1-2 through a cylindrical pin 6, and a locking hole 4-3 and a kidney-shaped hole 4-4 are correspondingly formed in the walkway plate 4 at the position corresponding to the walkway fixing plate 2-2 and the walkway limiting locking plate 1-3 respectively.

When the utility model is in a working state: the hinge holes 2-4 are connected with the first hinge structure through a pin shaft 7 and a cotter pin 8; the guardrail 3 is inserted into the sleeves 2-3 of the guardrail 3 and is fixed by a gasket 9 and a cotter pin 8; the walkway plate 4 falls on the cantilever beam 2, the walkway fixing plate 2-2 is connected with the locking hole 4-3 through a bolt, and the hinged circular pipe 4-2 is connected with the second hinged structure through a cylindrical pin 6. The pneumatic spring 5 is connected with a first pneumatic spring 5 connecting plate 1-4 and a second pneumatic spring 5 connecting plate 4-1. When folding: the bolts between the locking holes 4-3 and the walkway fixing plates 2-2 are taken down, the walkway plates 4 are turned over around the cylindrical pins 6 by means of the force of the pneumatic springs 5, the waist-shaped holes 4-4 and the walkway limiting locking plates 1-3 are connected through the bolts, the cantilever beams 2 are rotated to the side of the main beam frame 1, meanwhile, the guardrails 3 are rotated to one side, and then the bolts are inserted into the limiting holes 1-5, so that the cantilever beams 2 are limited. The folding process is reversed to open the walkway plates 4 and the guardrails 3 to the working state.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that changes may be made in the embodiments and/or equivalents thereof without departing from the spirit and scope of the utility model.
