Abstract
Description
Technical Field
[0001] This utility model relates to the field of shipbuilding, specifically to a safety protection device for ship holes. Background Technology
[0002] During the initial sectional assembly process of ship construction, there will be many holes on the surface of the hull structure, such as door openings, manholes, temporary process openings, etc. If these are not protected, construction workers will face significant safety hazards when working near these holes, and accidents such as stepping into gaps or falling may easily occur.
[0003] Safety protection devices are typically installed at ship openings to ensure safety. For example, Chinese Patent CN 106828775 discloses a telescopic opening protection device, which is installed on a steel plate above the opening. It includes three flat steel bars, a connecting bolt connecting the three flat steel bars, and three fixing bolts. The three flat steel bars have identical structures, with an adjusting section and a clamp at each end. The adjusting section has an adjusting groove, and the clamp has a fixing screw hole. The adjusting sections of all three flat steel bars extend to the center of the opening, and the connecting bolts are sequentially passed through the adjusting grooves to achieve a movable connection between the three flat steel bars. The clamps of the three flat steel bars are located above the steel plate, and the three fixing bolts pass through the fixing screw holes of the three flat steel bars to fix the clamps of the flat steel bars to the steel plate. However, this telescopic opening protection device only connects the three flat steel bars through the connecting bolt, and the fixing bolts are needed to fix the clamps to the steel plate, resulting in low load-bearing capacity and structural instability.

[0027] To better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings.
[0028] like Figures 1 to 4 As shown, this embodiment provides a ship hole safety protection device, including an H-shaped main support 1. The two parallel sides of the main support 1 have the same structure. A telescopic support 2 is slidably arranged inside the parallel sides. The telescopic support 2 includes two telescopic rods 7 and an elastic element 3. The two telescopic rods 7 are respectively arranged at both ends of the parallel sides. One end of the telescopic rod 7 extends out of the parallel side, and the other end of the telescopic rod 7 is arranged inside the parallel side. The two ends of the elastic element 3 are respectively connected to the telescopic rods 7 at both ends of the parallel side. The ends of the telescopic rods 7 that extend out of the parallel side are provided with forks for clamping the hull steel plate 8. An adjustment unit is provided between the parallel side and the telescopic support 2. The adjustment unit is used to adjust the length of the telescopic rods 7 extending out of the parallel side so that the ship hole safety protection device can be applied to holes of different diameters.
[0029] The adjustment unit includes bolts 5, with symmetrical adjustment slots 6 arranged on the parallel sides. The telescopic rod 7 has multiple threaded holes 4 that match the bolts 5. The bolts 5 pass through the adjustment slots 6 and connect to the different threaded holes 4 to fix the length of the telescopic rod 7 extending beyond the parallel sides. The elastic element 3 is in a compressed state, the slot length of the adjustment slots 6 is less than 1 / 2 the compression of the elastic element 3, and the length of the bolts 5 is greater than the depth of the threaded holes 4.
[0030] In this embodiment, the length of the adjusting slot 6 is 100mm, the bolt 5 is a wing bolt with a specification of M6X1.5mm and a length of 10mm, and the threaded hole 4 has a specification of M6X1.5mm and a depth of 5mm. Figure 1 , 3 As shown, the fork head is a Y-shaped fork head, so that the hull steel plate 8 can be inserted into the fork head.
[0031] In this embodiment, the elastic element 3 is a spring with an outer diameter of 25mm and a wire diameter of 2mm. The spring is connected to the end of the telescopic rod 7 located within the parallel side. The main support 1 is made of square tubing, and the telescopic rod 7 is made of square steel. The cross-sectional area of the telescopic rod 7 is smaller than that of the main support 1, but greater than or equal to the cross-sectional area of the spring. The main support 1 is 40x40x4mm in size, and the telescopic rod 7 is 30x30mm in size.
[0032] The working principle of the ship hole safety protection device in this application is as follows:
[0033] like Figure 4As shown, according to the size of the hole 9, adjust the length of the telescopic rod 7 extending out of the parallel side, and fix the forks of the two telescopic rods 7 at one end of the main support 1 onto the hull steel plate 8 on one side of the hole 9. Compress the elastic element 3 and place the ship hole safety protection device in the hole 9. Adjust the length of the two telescopic rods 7 extending out of the parallel side at the other end of the main support 1 until the elastic element 3 in the compressed state exerts force to fix the forks of the two telescopic rods 7 at the other end of the main support 1 onto the hull steel plate 8 on the other side of the hole 9. Fix the length of the telescopic rods 7 extending out of the parallel side at both ends of the main support, and stably set the ship hole safety protection device on the ship hole.
[0034] This application installs an H-shaped support bracket on the ship's opening, which increases the protective space of the protective device and can effectively prevent workers or objects from falling into the opening, thereby improving the protective effect of the ship's opening protection device.
[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of the invention or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solutions of the present invention, and all such modifications and substitutions should be covered within the scope of the technical solutions claimed in the present invention.
