[0002] The marine loading and unloading arm is a special equipment used for docking and loading and unloading with ships at port terminals. The vertical ladder, an important component on the loading and unloading arm, is a passage for personnel to go up and down the loading and unloading arm for inspection and maintenance.

[0003] The existing straight ladders still have the following problems: the existing straight ladders do not have a reliable standing surface for operators to rest when climbing up and down in harsh open-air marine operating environments and high-altitude working conditions, making the operation uncomfortable; the existing straight ladders do not have a reliable transition plane when operators cross between different straight ladders, making the operation unsafe. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing straight ladder has no reliable standing surface for operators to rest when climbing up and down in harsh open-air marine operating environments and high-altitude working conditions, which makes the operation uncomfortable; the existing straight ladder has no reliable transition plane when operators cross between different straight ladders, which makes the operation unsafe.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a straight ladder flip pedal device, including a longitudinal assembly fixing rod, a plurality of transverse climbing rods are welded and fixed on the outer side of the longitudinal assembly fixing rod, a lateral fixing base is bolted to the outer side of the longitudinal assembly fixing rod, a bottom assembly frame is welded and fixed on the outer side of the lateral fixing base, a flip-type large-area steel grating pedal is movably installed on the outer upper end of the bottom assembly frame through a rotating shaft, and a strip-shaped flip notch that matches the longitudinal assembly fixing rod is opened on the side wall of the flip-type large-area steel grating pedal.

[0006] Both sides of the transverse climbing rod are provided with lateral limiting plates of an integral structure bent upwards.

[0007] A bottom connecting bracket matching with a bottom assembly frame is welded and fixed on the lower surface of the flip-type large-area steel grating pedal.

[0008] An upper drainage hole is provided on the upper surface of the transverse climbing rod.

[0009] An elastic limiting mechanism is installed at a position corresponding to the strip-shaped flip notch on the inner side of the flip-type large-area steel grating pedal.

[0010] The elastic limiting mechanism includes a side guide box welded and fixed on the inner side of the flip-type large-area steel grid pedal, an internal telescopic block slidably inserted into the side guide box, and an extrusion spring installed on the inner end of the internal telescopic block and the inner side of the side guide box.

[0011] The beneficial effects of the utility model are:

[0012] (1) The utility model has an ingenious structure, safe and reliable operation, and low cost.

[0013] (2) The flip-type large-area steel grating pedal of the utility model adopts a flip-type structural design, which is convenient for flipping and storage;

[0014] (3) The flip-up large-area steel grid pedal has good structural stability after adjustment, which improves the comfort during rest. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0016] Figure 1 It is a schematic diagram of the structure of the utility model in the unfolded state.

[0017] Figure 2 It is a schematic diagram of the structure of the utility model in the storage state. DETAILED DESCRIPTION

[0018] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Figure 1 and Figure 2 The straight ladder flip pedal device shown comprises a longitudinal assembly fixing rod 1, three transverse climbing rods 2 are welded and fixed on the outer side of the longitudinal assembly fixing rod 1, a lateral fixing base 3 is bolted to the outer side of the longitudinal assembly fixing rod 1, a bottom assembly frame 4 is welded and fixed on the outer side of the lateral fixing base 3, a flip-type large-area steel grating pedal 5 is movably mounted on the outer upper end of the bottom assembly frame 4 through a rotating shaft, and a strip-shaped flip notch 6 matching the longitudinal assembly fixing rod 1 is opened on the side wall.

[0021] In order to improve the safety and limiting ability on both sides, the two sides of the transverse climbing pole 2 are provided with lateral limiting plates 7 of an integrated structure bent upwards.

[0022] In order to cooperate with the bottom movable assembly, a bottom connecting bracket 8 that matches the bottom assembly frame 4 is welded and fixed to the lower surface of the flip-type large-area steel grid pedal 5.

[0023] In order to improve the anti-slip property, an upper drainage hole is opened on the upper surface of the transverse climbing rod 2.

[0024] In order to cooperate with the limit control, an elastic limit mechanism 9 is installed at the position of the strip-shaped flip notch 6 on the inner side of the flip-type large-area steel grid pedal 5.

[0025] In order to cooperate with the lateral limitation, the elastic limiting mechanism 9 includes a side guide box 91 welded and fixed on the inner side of the flip-type large-area steel grid pedal 5, an internal telescopic block 92 slidably inserted into the side guide box 91, and an extrusion spring 93 installed on the inner end of the internal telescopic block 92 and the inner side of the side guide box 91.

[0026] The extrusion spring 93 squeezes the internal telescopic block 92 outward, so that when the flip-type large-area steel grating pedal 5 is flipped, the strip-shaped flip notch 6 is sleeved on the longitudinal assembly fixing rod 1, and then the internal telescopic block 92 is inserted into the strip-shaped flip notch 6 laterally from the outside to limit the other side of the longitudinal assembly fixing rod 1, so that the flip-type large-area steel grating pedal 5 cannot be flipped and reset; people can control the internal telescopic block 92 to slide inward and reset by controlling the control watch on the outside of the internal telescopic block 92, thereby separating the internal telescopic block 92 from the longitudinal assembly fixing rod 1, and the longitudinal assembly fixing rod 1 can be flipped and reset normally.

[0027] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
