[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1 - Figure 3The utility model provides an embodiment: an emergency ferry structure for a train, comprising a ferry body 1, which is used to connect the train with the external environment to form a passage so that passengers can pass through. The top of the ferry body 1 is fixedly connected with a mounting column 2, which is used to install or disassemble and fold the handrail 61 on the mounting assembly. The inner wall of the bottom end of the ferry body 1 is fixedly connected with a sliding column 3. The sliding column 3 is provided with three groups, which are used to improve the stability of the baffle 51 and the supporting strength of the ferry body 1. The bottom end of the ferry body 1 is fixedly connected with a reinforcing block near two adjacent groups of sliding columns 3. 4, used to improve the supporting strength of the ferry board body 1, and at the same time, a limiting groove 53 identical to that on the slide column 3 is opened on the reinforcing block 4, and a limiting component is arranged on the outer wall of the slide column 3 to improve the stability of the ferry board body 1 when it is placed, and the limiting component includes a baffle 51, and both sides of the top of the baffle 51 pass through and are slidably connected to the outer wall of the slide column 3, and both sides of the baffle 51 are arranged as inclined surfaces, so that the baffle 51 can make the ferry board body 1 more stable when facing different height differences, and the inner wall of the baffle 51 is vertically slidably connected with a limiting plate 52, which is used to insert the limiting groove 53 to limit the baffle 51.

[0033] Reference Figure 2 - Figure 4 The bottom end of the sliding column 3 is provided with a limiting groove 53 near the top of the limiting plate 52, which is used in conjunction with the limiting plate 52, and can be quickly and stably adjusted according to the erection requirements of the ferry body 1, thereby improving the installation efficiency. The top of the limiting plate 52 slides on the inner wall of the bottom end of the limiting groove 53, and the limiting plate 52 and the baffle 51 are elastically connected through the compression spring 54. The top end of the compression spring 54 is fixedly connected to the bottom end of the limiting plate 52, and the bottom end of the compression spring 54 is fixedly connected to the inner wall of the bottom end of the baffle 51. The elastic force of the compression spring 54 ensures the close fit between the limiting plate 52 and the limiting groove 53, and the limiting is improved by multiple groups of compression springs 54. To ensure the stability of the plate 52, the inner wall in the middle of the bottom end of the limit plate 52 is rotatably connected to the limit rod 55, which is used to pull the limit plate 52 out from the inner wall of the limit groove 53, thereby releasing the limit on the baffle 51. The outer wall of the bottom end of the limit rod 55 is slidably connected to the inner wall of the bottom end of the baffle 51. The right side of the top end of the limit plate 52 is set as an inclined surface. When the baffle 51 is pulled to both sides of the ferry board body 1, the baffle 51 can be pulled quickly and at the same time, the baffle 51 can be prevented from moving toward the inside of the ferry board body 1. The right side inclined surface of the limit groove 53 is attached to the inclined surface of the top end of the limit plate 52. The shape of the limit groove 53 is the same as the top end of the limit plate 52, so that the limit plate 52 can slide in one direction.

[0034] Reference Figure 1 and Figure 2There are two groups of baffle plates 51 and limit plates 52, and the two groups of baffle plates 51 and limit plates 52 are symmetrically arranged with the center line of the sliding column 3 as the symmetry axis, which can quickly limit the two sides of the ferry board body 1, thereby improving the installation efficiency of the ferry board body 1. There are multiple groups of limit grooves 53, and the multiple groups of limit grooves 53 are symmetrically arranged with the center line of the sliding column 3 as the symmetry axis. There are two groups of mounting columns 2, and the left group of mounting columns 2 is shorter than the right group of mounting columns 2. Through the different height settings, the handrails 61 can be folded with each other when disassembled.

[0035] Reference Figure 1 and Figure 5 A mounting assembly is provided at the top of the mounting column 2, and the mounting assembly includes a handrail 61, which provides support and stability for passengers, so that passengers can maintain balance when passing the ferry. The bottom end of the handrail 61 is hinged to the inner wall of the top of the mounting column 2, so that it can be folded and unfolded for easy storage. The outer wall of the handrail 61 is slidably connected with a sliding sleeve 62, which is used to support the connection point between the handrail 61 and the mounting column 2, so that the handrail 61 is in a vertical state. The bottom end of the sliding sleeve 62 is rotatably connected with a rotating cylinder 63, which is used in conjunction with a threaded protrusion 64 to fix the sliding sleeve 62, thereby improving the stability of the handrail 61. The outer wall of the mounting column 2 is provided with a threaded protrusion 64, and the inner wall of the rotating cylinder 63 is threadedly connected to the outer wall of the mounting column 2 through the threaded protrusion 64. A sliding groove is provided on the outer wall of the handrail 61, and the inner wall of the sliding sleeve 62 slides on the inner wall of the sliding groove, and the sliding groove prevents the sliding sleeve 62 from rotating.

[0036] Working principle: During use, when the ferry plate is needed, first pull the baffle plate 51 according to the position where the ferry plate needs to be placed, so that the baffle plate 51 slides on the outer walls of the three groups of sliding columns 3, and at the same time, the limit plate 52 slides on the inner walls of the limit grooves 53 on the sliding columns 3 and the reinforcement blocks 4 through the inclined surface. When the baffle plate 51 moves to the appropriate position, stop moving the baffle plate 51, and the limit plate 52 slides into the inner wall of the limit groove 53 through the elastic force of the compression spring 54 to fix the limit plate 52.

[0037] At this time, move the ferry body 1 to press one side of the baffle 51 against the outer wall of the position where it needs to be placed, and repeat the above operation to move the baffle 51 at one end close to the train close to the outer wall of the train. At this time, the installation of the ferry is completed.

[0038] When the handrail 61 needs to be installed, the handrail 61 is first erected and perpendicular to the mounting column 2. At this time, the sliding sleeve 62 is moved downward along the outer wall of the handrail 61 so that the sliding sleeve 62 wraps the connection point between the handrail 61 and the mounting column 2. At this time, the rotating drum 63 is threadedly connected with the threaded protrusion 64 through the thread on the inner wall of the rotating drum 63, and the rotating drum 63 and the sliding sleeve 62 are fixed to the outer wall of the mounting column 2, thereby fixing the handrail 61 and making the handrail 61 in a vertical state. Repeat the above operation, and then install multiple groups of mounting columns 2 and handrails 61 in turn, thereby improving the installation efficiency of the device.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
