DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Example 1
[0024] See also Figure 1-4 The present embodiment provides an anti-fall protection device used in ship construction, which comprises a main steel pipe 1 and two auxiliary steel pipes 2. The two auxiliary steel pipes 2 are welded to the front and rear ends of the main steel pipe 1 one by one. A notch 5 is opened at the left end of the main steel pipe 1, and a main cut 6 with a half cross section is cut at the right end of the main steel pipe 1. The outer ends of the auxiliary steel pipes 2 are cut with auxiliary cuts 13 with half cross sections. The main steel pipe 1 and the auxiliary steel pipes 2 are combined into a "cross" structure.
[0025] When in use, the end of the main steel pipe 1 in the anti-fall device with the slot 5 is inserted into one side of the passage hole or the lightening hole, and the inner wall of the slot 5 is against the passage hole or the lightening hole. Then, one end of the main cutout 6 on the main steel pipe 1 of the anti-fall device is placed on the other side of the passage hole or the lightening hole, and at the same time, the secondary cutout 13 of the secondary steel pipe 2 is placed on the front and rear parts of the upper end of the passage hole or the lightening hole, so as to form the effect of blocking the passage hole or the lightening hole.
[0026] In summary, by combining the main steel pipe 1 and the auxiliary steel pipe 2 and setting them up on the passage hole or the lightening hole, a simple, eye-catching, easy-to-install and disassemble anti-fall protection device is formed, and the main steel pipe 1 and the auxiliary steel pipe 2 are combined into a "cross" structure, which helps to prevent some people from falling from the passage hole or the lightening hole, thereby avoiding personal safety accidents and providing protection measures for the life safety of people.
[0027] Example 2
[0028] On the basis of Example 1, a stop block 8 is provided in the main incision 6, a sliding sleeve 7 is fixed on the left side of the stop block 8, the sliding sleeve 7 is sleeved on the outer periphery of the main steel pipe 1, fixed blocks 9 are fixed on the left and right sides of the upper end of the main steel pipe 1, a guide rod 11 is fixed between the two fixed blocks 9, the sliding sleeve 7 is slidably connected with the guide rod 11, a threaded locking rod 10 is rotatably passed through the two fixed blocks 9, the sliding sleeve 7 is threadedly connected with the threaded locking rod 10, and handles are welded on both ends of the threaded locking rod 10.
[0029] When the device is set up on the channel hole or the lightening hole, in order to prevent the device from accidentally sliding, the threaded locking rod 10 is twisted by the handle to drive the sliding sleeve 7 to slide along the guide rod 11. In this process, the sliding sleeve 7 drives the stop block 8 to press against the inner wall of the channel hole or the lightening hole. Since the inner wall of the groove 5 presses against the inner wall of the channel hole or the lightening hole, and the stop block 8 presses against the inner wall of the channel hole or the lightening hole, left and right tensioning and limiting measures are formed, so that the device is fixed on the channel hole or the lightening hole, thereby preventing the device from accidentally sliding during use and effectively improving the safety and stability of the device during use.
[0030] In this embodiment, the top of the notch 5 and the main incision 6 are connected to the first anti-skid pad 12, and the top of the auxiliary incision 13 is connected to the second anti-skid pad 14. By arranging the first anti-skid pad 12 at the top of the notch 5 and the main incision 6, and arranging the second anti-skid pad 14 at the top of the auxiliary incision 13, it is beneficial to improve the friction force on the channel hole or reduce the hole after the main steel pipe 1 and the auxiliary steel pipe 2 are installed, so as to better prevent the device from accidentally sliding.
[0031] In this embodiment, a column 3 is welded in the middle of the main steel pipe 1, and a fluorescent signal stick 4 is fixed on the top of the column 3. By arranging the fluorescent signal stick 4 on the column 3, the light emitted by the fluorescent signal stick 4 serves as a warning to remind surrounding personnel and better prevent falling accidents.
[0032] Insert one end of the main steel pipe 1 with the notch 5 in the anti-fall device into one side of the passage hole or the lightening hole, and the inner wall of the notch 5 presses against the passage hole or the lightening hole. Then, place one end of the main cutout 6 of the main steel pipe 1 of the anti-fall device on the other side of the passage hole or the lightening hole, and at the same time, place the secondary cutout 13 of the secondary steel pipe 2 on the front and rear of the upper end of the passage hole or the lightening hole, so as to form the effect of blocking the passage hole or the lightening hole. Then, turn the threaded locking rod 10 by the handle and drive the sliding sleeve 7 to slide along the guide rod 11. During this process, the sliding sleeve 7 drives the block 8 to press against the inner wall of the passage hole or the lightening hole. Since the inner wall of the notch 5 presses against the inner wall of the passage hole or the lightening hole, and then the block 8 presses against the inner wall of the passage hole or the lightening hole, a left and right tensioning limit measure is formed to achieve the effect of fixing the device on the passage hole or the lightening hole.
[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
