Description

Technical Field

[0001] The present invention relates to the field of engineering machinery passages, and in particular to a disassembly-free integrated transport staircase device. Background Art

[0002] Existing stairs and steps for construction machinery are categorized by structure into folding and non-folding types, and by transportation method into disassembly and random transport. Combining these two classifications, stairs and steps are primarily categorized into folding for random transport, folding for disassembly and transport, non-folding for random transport, and non-folding for disassembly and transport.

[0003] Non-folding stairs and steps are divided into two categories according to the application components and transportation size requirements: those that do not affect the transportation size and can be transported directly with the components, with the operation and transportation status consistent; non-folding stairs and steps that affect transportation are the most common, and the usual practice is to disassemble and transport them.

[0004] Ladders that do not affect transport dimensions do not require disassembly and have a relatively simple structure. Ladders that require disassembly are often transported by hanging them on the main unit. This only offers advantages in terms of transport space utilization, but customers still need manual labor or auxiliary lifting tools to complete disassembly and assembly during use.

[0005] Existing ladders have the disadvantages of requiring disassembly and assembly for transportation; being inconvenient for one person to disassemble and assemble; and requiring a large clearance between the shaft holes to facilitate disassembly and assembly, which can cause shaking when stepped on. Therefore, it is necessary to develop a new type of transport staircase device to overcome these problems. Summary of the Invention

[0006] Purpose of the invention: In view of the shortcomings and defects of the existing technology, the present invention provides an integrated transport staircase device that does not require disassembly and assembly, and can achieve random transportation through simple operation by one person; it solves the problem that the stairs are inconvenient to disassemble and assemble and cannot be operated by one person; it saves time and effort and saves use costs.

[0007] Technical solution: The present invention is an integrated transport staircase device that does not require disassembly and assembly, which is characterized by: comprising an integrated non-folding staircase main body, a staircase fixing axis device, a staircase top screw, a staircase limiting and fixing axis 1, a staircase limiting and fixing axis 2, a staircase limiting and fixing axis 3, a transport fixing device and a staircase top screw mounting hole; the integrated non-folding staircase main body is connected to the staircase fixing axis device, and the integrated non-folding staircase main body is connected to the external mounting platform through the staircase limiting and fixing axis 1, the staircase limiting and fixing axis 2, and the staircase limiting and fixing axis 3; the staircase top screw is installed in the staircase top screw mounting hole; the external mounting platform is provided with a transport fixing device.

[0008] Among them, the external mounting platform is provided with a lug structure for the stair limiting and fixing axis 1, the stair limiting and fixing axis 2, and the stair limiting and fixing axis 3 to pass through.

[0009] Wherein, the lug structures are arranged in groups of two and side by side.

[0010] Wherein, the integrated non-folding staircase body is a non-folding structure, and the integrated non-folding staircase body is provided with a plurality of steps.

[0011] Wherein, the staircase fixing shaft device connects the integral non-foldable staircase body and the external installation platform.

[0012] Wherein, the stair top screw is inserted into the stair top screw installation hole to avoid shaking caused by gap.

[0013] The method for using the disassembly-free integrated transport staircase device of the present invention is characterized in that: the integrated non-folding staircase main body is connected to the staircase fixed axis device, the integrated non-folding staircase main body is connected and fixed to the external mounting platform through the staircase limit and fixed axis 1, the staircase limit and fixed axis 2, and the staircase limit and fixed axis 3, and then the staircase top screw is installed in the staircase top screw installation hole. By adjusting the position of the staircase top screw, the staircase top screw is pushed onto the main body plane of the external mounting platform to avoid shaking caused by the gap.

[0014] Among them, by removing the stair limit and fixed axis 1, the stair limit and fixed axis 2, and the stair limit and fixed axis 3, the integrated non-folding stair body is rotated 270° around the stair fixed axis device, the stair limit and fixed axis 1 is fixed on the stair fixed axis device, and the stair limit and fixed axis 2 is fixed on the transport fixing device to achieve the fixation of the stairs in the transport state.

[0015] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: the present invention belongs to the category of non-folding random transportation, which reduces manpower and improves operational convenience; optimizes structural design and improves stepping stability; at the same time, since many users find it cumbersome to disassemble and assemble the channel during construction, they do not install the channel for operation, and the non-disassembly ladder indirectly improves the safety of the operation and the economy of operation and maintenance. The present invention realizes the non-disassembly and assembly transportation of integrated non-folding stairs and steps: only a few pins need to be removed, and they can be moved after rotation and tightening. The present invention realizes the non-disassembly and assembly of the channel fixing devices on both sides of the main unit: the fastening device adopts a hidden design, which does not exceed the main unit structure and can meet the assembly requirements of stairs and steps. The present invention saves labor and reduces operation and maintenance costs; the non-disassembly and assembly design effectively avoids the safety hazards caused by users not assembling the channel during use for personal reasons, and has good social benefits.

[0026] The external mounting platform is equipped with lug structures for stair limit and fixing axis 1 4, stair limit and fixing axis 2 5, and stair limit and fixing axis 3 6 to pass through. The lug structures are arranged in pairs, side by side. The integrated non-folding staircase body 1 is a non-folding structure with several steps. The stair fixing axis device 2 connects the integrated non-folding staircase body 1 to the external mounting platform. The stair jack screw 3 is inserted into the stair jack screw mounting hole 8 to prevent shaking caused by clearance.
