Description

Technical Field

[0001] This application relates to the technical field of marine climbing equipment, and in particular to a marine trailer climbing device. Background Art

[0002] At present, suitable climbing ladders have been lacking for material yard trailers for a long time. Workers usually rely on the trailer towing bar to get on and off the trailer, with a relatively high risk factor. Due to the large height difference between the trailer towing bar and the trailer board surface, there are situations where workers climb and jump when getting on and off the trailer, with a relatively high safety risk and a potential safety hazard of falling.

[0003] Falling from a height is a high-incidence accident type in the shipbuilding industry, with a relatively high accident fatality rate. In history, many high-fall death accidents have occurred due to accidental climbing and falling. Through the analysis of high-fall accident cases in the shipbuilding industry, it can be concluded that the main reasons for the frequent occurrence of high-fall accidents are various factors such as slipping and improper climbing during the climbing process. Therefore, the primary safety guarantee for climbing is to have three points of support to ensure correct climbing. Utility Model Content

[0031] The utility model provides a ship trailer climbing device, such as Figures 1 to 3 As shown, the ship trailer climbing device comprises a base frame 1, a step frame 2 and a step board 3.

[0032] In the following description, reference will be made to Figures 1 to 3 The specific structure of the above components of the marine trailer climbing device and the connection relationship of the above components are specifically described.

[0033] like Figures 1 to 3 As shown, in the embodiment, the step frame 2 can be installed on the upper part of the base frame 1. The step board 3 can be installed on the step frame 2. The workers can get on and off the ship trailer by climbing the step frame 2, so that the workers are protected when getting on and off the trailer, thereby greatly reducing the risk of falling from a height from a technical perspective, essentially ensuring the safety of construction workers and improving work efficiency.

[0034] Preferably, Figures 1 to 3 As shown, in the embodiment, the base frame 1 can be formed as a rectangular frame, that is, the base frame 1 is surrounded in a rectangular shape. The step frame 2 can be erected on the rectangular base frame 1, so that the overall structure of the ship trailer climbing device is more stable and easy for workers to climb.

[0035] Further, preferably, Figures 1 to 3 As shown, in an embodiment, the base frame 1 may include four connecting rods 10 connected end to end in sequence. Specifically, the connecting rod 10 may be a channel steel, that is, four channel steels are connected end to end in sequence to form a rectangle. The step frame 2 may be bolted or welded to the top surface of the base frame 1. Preferably, the length of the base frame 1 may be 750 mm, and the width of the base frame 1 may be 600 mm.

[0036] More preferably, Figure 3 As shown, in the embodiment, a triangle plate 11 can be installed on the inner side of the four top corners of the base frame 1. Specifically, the triangle plate 11 can be a right-angled triangle plate. The base frame 1 is surrounded into a rectangle, and a triangle plate 11 is provided at each of the four top corners of the rectangle. The two right-angled sides of the triangle plate 11 are respectively fixedly connected to the two adjacent connecting rods 10 (which can be welded), thereby supporting the base frame 1 to ensure the strength of the base frame 1. In addition, chamfers or arc grooves can be provided at each top corner of the triangle plate 11 to avoid scratches between the corners of the triangle plate 11 and the base frame 1.

[0037] Preferably, Figures 1 to 3 As shown, in the embodiment, the step frame 2 may include a crossbeam 21, a longitudinal beam 22, a column 23 and a connecting column 24. The number of the crossbeams 21 may be multiple. The multiple crossbeams 21 may be arranged along the longitudinal direction (i.e., Figure 1 or Figure 2They are arranged at intervals in the horizontal direction (as shown in [reference]), and the heights of the multiple cross beams 21 increase successively in the longitudinal direction. Specifically, the heights of the multiple cross beams 21 can gradually increase in the first direction, and the first direction can be, for example, as Figure 1 shown as the direction from right to left in [reference]. The number of longitudinal beams 22 can also be multiple, and the longitudinal beams 22 are perpendicular to the cross beams 21. The longitudinal beams 22 can be welded and fixed at both ends of the cross beams 21. The number of columns 23 can be multiple, and the columns 23 are perpendicular to the cross beams 21 and the longitudinal beams 22. The top end of the column 23 is welded to the rear end of the longitudinal beam 22 in the first direction (i.e., the end close to the right side as described in Figure 1 [reference]), and the bottom end of the column 23 is welded to the front end of the longitudinal beam 22 in the first direction (i.e., the end close to the left side as described in Figure 1 [reference]). Thus, the multiple cross beams 21, the multiple longitudinal beams 22, and the multiple columns 23 are connected into a framework. The connecting column 24 can be arranged in the vertical direction, that is, the connecting column 24 is parallel to the column 23. The top end of the connecting column 24 can be welded to the front end of the longitudinal beam 22 at the end of the step framework 2 in the first direction, and the bottom end of the connecting column 24 can be welded to the front end of the base framework 1 in the first direction, thereby supporting the entire step framework 2 and connecting the step framework 2 and the base framework 1.

[0040] In addition, preferably, as Figures 1 to 3As shown, in an embodiment, the ship trailer climbing device can be formed into a stepped shape. That is, the frame formed by connecting multiple cross beams 21, multiple longitudinal beams 22 and multiple columns 23 is also stepped, so as to facilitate the staff to climb. More preferably, the ship trailer climbing device can be formed into a four-layer structure in the vertical direction, that is, the ship trailer climbing device is formed into a four-layer ladder (the number of the columns 23 is six) to adapt to the height of the platform of the ship trailer.

[0041] Further, preferably, Figures 1 to 3 As shown, in the embodiment, the front end of the step frame 2 in the first direction can be aligned with the front end of the base frame 1 in the first direction. The rear end of the step frame 2 in the first direction can be located in the middle of the base frame 1 in the first direction (i.e., located in the middle of the long side of the base frame 1), so that the ship trailer climbing device forms a four-layer stepped structure, and the ship trailer climbing device can be laid with step boards 3 on each layer except the top layer.

[0042] In addition, preferably, Figure 1 As shown, in the embodiment, a universal wheel 100 with brakes can be installed at the bottom of the step frame 2. The number of the universal wheels 100 with brakes can be four, and the four universal wheels 100 with brakes can be installed at the bottom of the four corners of the base frame 1 respectively, so as to facilitate the movement of the marine trailer climbing device.

[0043] During use, the staff can first park the trailer in a stable place and put in the brake block to reinforce the trailer itself. Then place the marine trailer climbing device on a flat ground near the trailer side. After adjusting the position, press the brake button of all the braked universal wheels 100 of the marine trailer climbing device to prevent the marine trailer climbing device from sliding during the climbing process. After use, the staff can move the marine trailer climbing device to a nearby parking lot, which is flexible and controllable.
