Description

Technical Field

[0001] The utility model relates to the technical field of ship vertical ladders, in particular to a vertical ladder protection device which can be quickly disassembled and assembled and is self-locking. Background Art

[0002] During ship construction, some vertical ladders on bulkheads lack guardrails, posing a safety hazard and risk to workers as they ascend and descend. In the absence of safety guardrails, workers could potentially fall directly onto the multi-story platform. Falling from multiple levels presents a high risk of fatal injury. To address this issue, a safety collar is designed to prevent falls.

[0003] Currently, most safety collars used on ship ladders are welded, which is time-consuming, labor-intensive, and difficult to adjust. Welding also damages the paint coating on the ladder surface, requiring tedious manual repainting after installation. Existing detachable ladder collars are often fastened with bolts, making assembly and disassembly difficult and risking bolts falling during use. Therefore, a fast, self-locking ladder protection device with a stable structure that allows for quick assembly and disassembly is needed, saving time and effort. Summary of the Invention

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a ladder protection device that can be quickly disassembled and self-locked, so as to realize the rapid disassembly and assembly of the safety protection ring, thereby improving safety and working efficiency.

[0005] The purpose of this utility model is achieved in this way:

[0006] A quickly disassembled and self-locking ladder protection device comprises a protection ring and a safety net. The protection ring is connected to the safety net and is arranged on the ladder. Each ladder is provided with at least three protection rings. A safety platform is provided below the ladder. The ladder comprises two vertically arranged parallel flat ladder posts, with a plurality of equally spaced crossbars arranged between the two flat ladder posts.

[0007] The protection ring includes a circular guardrail with an opening. The left end of the opening of the circular guardrail is connected to a left lock buckle via a left bent portion, and the right end is connected to a right lock buckle via a right bent portion. The right lock buckle and the left lock buckle have the same structure and are symmetrically arranged.

[0008] The left lock buckle includes a U-shaped buckle, the opening of the U-shaped buckle faces the circular guardrail, the left end of the open end of the U-shaped buckle is connected to the left bent part, and the bottom of the right end is connected to the top of the clamping rod, and the bottom end of the clamping rod is connected to the blocking rod. The clamping rod is vertically arranged between the U-shaped buckle and the blocking rod, and the blocking rod is arranged horizontally parallel to the U-shaped buckle.

[0009] Furthermore, the width of the circular guardrail opening is at least 20 mm smaller than the distance between two straight ladder flat columns of the straight ladder.

[0010] Furthermore, the opening spacing of the U-shaped buckles and the thickness of the straight ladder flat columns are correspondingly the same.

[0011] Furthermore, the length of the blocking rod does not exceed the width of the flat column of the straight ladder; and the length of the clamping rod is less than the distance between the two cross bars.

[0012] Furthermore, the circular guardrail on the protection circle is connected with a safety net, and a safety net is provided between two adjacent protection circles on the straight ladder.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model provides a straight ladder protection device that can be quickly disassembled and self-locked. It has a simple and lightweight structure. A self-locking buckle is respectively arranged at both ends of the opening of the circular guardrail, which makes it convenient and quick to disassemble the safety protection ring, thereby improving safety and working efficiency. In addition, the protection ring structure of the utility model is an integrated type, and there is no need to add additional accessories and connecting parts such as bolts and nuts to the device, which can avoid the risk of falling after the connecting parts become loose, further increasing safety performance and saving time and effort.

As shown in the figure, the present invention relates to a quickly removable and self-locking ladder protection device comprising a protective ring 1 and a safety net 2. The protective rings 1 are mounted on ladders 3, with at least three protective rings 1 installed on each ladder 3. A safety platform 4 is located below the ladders 3.

[0025] The vertical ladder 3 includes two vertically arranged flat ladder columns 31 , and a plurality of horizontal bars 32 are arranged equidistantly between the two flat ladder columns 31 .

[0026] The protection ring 1 includes a circular guardrail 11, which has an opening. The width of the opening is at least 20 mm smaller than the distance between the two straight ladder flat columns 31 of the straight ladder 3;

[0027] The left end of the opening of the circular guardrail 11 is connected to the left lock buckle 13 through the left bent portion 12, and the right end is connected to the right lock buckle 15 through the right bent portion 14. The right lock buckle 15 and the left lock buckle 13 have the same structure and are symmetrically arranged;

[0028] The left lock buckle 13 includes a U-shaped buckle 131, the opening of the U-shaped buckle 131 faces the circular guardrail 11, the left end of the open end of the U-shaped buckle 131 is connected to the left bent portion 12, and the bottom of the right end is connected to the top of a clamping rod 132, and the bottom end of the clamping rod 132 is connected to a blocking rod 133.

[0033] Working principle:

[0034] The utility model provides a quick-dismountable and self-locking vertical ladder protection device. The size of the quick-dismountable and self-locking protection ring needs to be made according to the size of the vertical ladder on the bulkhead of the actual ship:

[0035] (1) Measure the distance between the flat steel bars on both sides of the vertical ladder (i.e. the flat columns of the vertical ladder) to determine the opening size of the guardrail. The width of the guardrail opening should be at least 20mm smaller than the distance between the flat steel bars on both sides of the vertical ladder;

[0036] (2) Measure the size of the flat steel on both sides of the vertical ladder and determine the size of the left and right lock buckles of the guardrail self-locking. The width of the left and right lock buckles should be the same as the thickness of the flat steel;

[0037] (3) Use round steel to bend the guardrail according to the size;

[0038] (4) Connect a safety net (using materials such as three-proof cloth) outside the guardrail to form a relatively closed safety area;

[0039] (5) Install the prepared safety guardrails and safety nets on the bulkhead ladder.

[0040] join Figure 5 , Figure 5 The following is a schematic diagram of the installation process of the present invention. As shown in the figure, the present invention provides a quick-disassembly and self-locking ladder protection device. The installation process is as follows:

[0041] Step 1: Push the guardrail outwards so that the guardrail opening is larger than the distance between the flat columns of the straight ladder;

[0042] Step 2: Insert the guardrail horizontally to the top of the horizontal bar of the ladder and stop applying outward force;

[0043] Step 3: Lift the outer end of the guardrail diagonally upwards, using the left and right locks of the guardrail as contact points. The left and right U-shaped locks are clamped on the straight ladder flat columns on both sides. Both left and right U-shaped locks are set on the horizontal bar, and then the whole thing is lowered flat;

[0044] Step 4: Lay it flat to achieve self-locking.

[0045] Note: If the guard ring sags due to construction accuracy or long-term use, you can bend the left and right bent parts upward at a certain angle to make the guard ring perpendicular to the vertical ladder.

[0046] The above are only specific application examples of the present invention and do not constitute any limitation on the scope of protection of the present invention. Any technical solution formed by equivalent transformation or equivalent replacement shall fall within the scope of protection of the present invention.
