[0039] First, the sea-side trapezoidal frame according to the embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0040] The sea-side trapezoidal frame 100 according to the embodiments of the present invention, as Figure 1 shown, includes: a pair of columns 110, a box body 120, a plurality of support assemblies 130, a plurality of platforms 140 and a ladder 150.

[0041] Wherein, a pair of columns 110 are arranged oppositely and the distance between the top ends is less than the distance between the bottom ends.

[0042] The box body 120 is connected to the tops of the two columns 110.

[0043] The support assemblies 130 are arranged in a staggered manner up and down on both sides of the axial direction of one side column 110.

[0044] The platform 140 is arranged on the support assembly 130.

[0045] The ladder 150 is connected to a plurality of platforms 140 in sequence from bottom to top and is arranged on one side column 110.

[0046] Specifically, the seaside trapezoidal frame 100 according to the embodiment of the present invention is provided with a pair of oppositely arranged columns 110. The distance between the tops of this pair of columns 110 is set to be smaller than the distance between the bottoms. A box body 120 is installed and connected at the top thereof. On one side column 110, a plurality of support assemblies 130 are respectively arranged on both sides in the axial direction from top to bottom in sequence. A platform 140 is connected on the plane formed by the support assemblies 130 for operators to stay. The upper and lower platforms 140 are connected by a ladder 150. The operator can perform climbing operations through the ladder 150 until reaching the box body at the top of the column 110.

[0047] In the seaside trapezoidal frame 100 according to the embodiment of the present invention, the support assemblies 130 are arranged in a staggered manner up and down on both sides of the axial direction of one side column 110. By connecting and arranging the platform 140 on the support assembly 130 and connecting the platforms 140 in sequence up and down through the ladder 150, the overall structure is stable, safe and reliable, ensuring the operation safety of the operators.

[0048] It should be noted here that the support assembly 130, the platform 140 and the ladder 150 in the embodiment of the present invention are not limited to being arranged on one side column 110, and there is also an implementation manner in which they can be arranged on both side columns 110 according to the actual application conditions.

[0049] Furthermore, the ladder 150 connects the bottom of the column 110 and the box body 120 at the top of the column 110.

[0050] That is to say, by arranging the ladder 150 connected up and down on the column 110, the operator can perform climbing operations through the ladder 150, which is convenient and reliable.

[0051] In some embodiments, the ladder 150 is in a rising spiral shape and connects a plurality of platforms 140 and the box body 120 in sequence.

[0052] That is to say, the ladder 150 is arranged in a rising spiral shape to connect a plurality of platforms 140 and the box body 120. In this way, the ladder 150 spirally climbs and connects to the column 110, with reliable force and stable structure.

[0053] In some embodiments, the ladder 150 includes multiple inclined ladders, and the multiple inclined ladders are connected to adjacent platforms 140 and the box body 120 in sequence from bottom to top.

[0054] That is to say, the ladder 150 is arranged in the form of multiple inclined ladders, and the multiple inclined ladders are sequentially and alternately connected above and below the column body 110, which is easy to implement and has relatively stable and reliable structure.

[0055] In some embodiments, the support assembly 130 includes: a square tube, one end of the square tube is connected to the surface of the column body 110, the other end extends outward, and a platform 140 is arranged on the upper surface of the square tube.

[0056] That is to say, by sequentially connecting and arranging square tubes extending outward above and below the column body 110 as support points, and the platform 140 is connected to the square tubes, the structure is simple and reliable and is easy to implement.

[0057] In some embodiments, as Figure 2 、 3 、shown in FIG. 5, the support assembly 130 includes: two connecting plates 131 and a fixed tube 132.

[0058] Wherein, the sides of the two connecting plates 131 are parallel and opposite to each other, and one ends are respectively connected to both sides of the center line of one side surface of the column body 110, and the other ends extend outward.

[0059] Both ends of the fixed tube 132 are respectively connected to the sides of the other ends of the two connecting plates 131.

[0060] Wherein, a platform 140 is arranged on the upper surface formed by the connecting plate 131 and the fixed tube 132 together.

[0061] Specifically, the support assembly 130 is provided with a pair of connecting plates 131. The pair of connecting plates 131 are opposite to each other, and one ends are respectively connected to both sides of the center line of the surface of the column body 110, and the other ends of the pair of connecting plates 131 are respectively connected through the fixed tube 132 to form an integral support assembly 130, and a platform is connected and arranged on the support assembly 130. The support assembly 130 is fixedly connected to the surface of the column body 110 in this form, with high structural strength and stability, making the installation of the platform more secure.

[0062] Further, one end of the connecting plate 131 is linearly connected to the surface of the column body 110 along the axial direction of the column body 110, and both ends of the fixed tube 132 are vertically connected to the other ends of the two connecting plates 131 respectively.

[0063] That is to say, the connecting plate 131 is attached to the surface of the column body 110 and is linearly fixedly welded to the column body 110 along the axis, and is respectively and vertically fixedly connected to the extending ends of the two connecting plates 131 through a fixed tube 132, making the overall structure of the support assembly 130 stable.

[0064] In addition, the butt weld between the connecting plate 131 and the column 110 is set as a straight line segment, avoiding trimming, with low operation difficulty and high quality. At the same time, the angles and positions of the support assemblies 130 on both sides of the column 110 are unified, enabling integral sandblasting after pre-welding in place on the column 110, improving the effect of integral structure sandblasting.

[0065] In some embodiments, as Figure 4 shown, the support assembly 130 further includes: at least two reinforcing plates 133.

[0066] Among them, the reinforcing plates 133 are connected to the connection between the connecting plate 131 and the fixed pipe 132.

[0067] That is to say, by providing the reinforcing plates 133 at the connection between the connecting plate 131 and the fixed pipe 132, the stability of the support assembly 130 is enhanced.

[0068] In some embodiments, the column 110 is a square pipe or a circular pipe.

[0069] That is to say, the column 110 is set in the form of a square pipe or a circular pipe to adapt to the working condition usage requirements, making the overall structure stable and reliable.

[0070] Furthermore, both ends of the bottom of the box body 120 are respectively connected to the tops of two columns 110.

[0071] Specifically, the bottom of the box body 120 is respectively and reliably supported on the tops of two columns 110, enabling operators to climb up the box body 120 through the ladder 150 from the bottom of the column 110 for operation.

[0072] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
