It should be noted that the body 121 can also be connected to the first pillar 111 and the second pillar 112 through other parts, and the embodiment of the present application does not limit the specific positions of the first pillar 111 and the second pillar 112 relative to the body 121.

[0074] For example, the main body 121 can be fixedly connected to the first pillar 111 and the second pillar 112 through the second side wall 1212, so that the first pillar 111 and the second pillar 112 are respectively located at one end of the second side wall 1212 close to the first side wall 1211 and the third side wall 1213; for another example, the main body 121 can also be fixedly connected to the first pillar 111 through the first side wall 1211 and fixedly connected to the second pillar 112 through the third side wall 1213, so that the first pillar 111 and the second pillar 112 are respectively arranged adjacent to the first side wall 1211 and the third side wall 1213; for another example, the main body 121 can also be fixedly connected to the first pillar 111 and the second pillar 112 through the table top 1215, so that the first pillar 111 and the second pillar 112 are arranged through the table top 1215.

[0075] It should also be noted that the support assembly 110 may further include other pillars such as a third pillar (not shown in the figure) and a fourth pillar (not shown in the figure), and the positions of other pillars such as the third pillar and the fourth pillar relative to the body 121 may be set with reference to the first pillar 111 and the second pillar 112. By providing more pillars, the stability of the platform 120 is improved, thereby improving the safety of the safety device 100.

[0076] The table top 1215 and the handrail 1216 can be made of metal materials such as iron, steel or aluminum alloy, so that the body 121 has high hardness and strength; the table top 1215 and the handrail 1216 can also be made of non-metal materials such as hard plastic, so that the body 121 has a lighter weight; the table top 1215 can also be made of metal materials such as iron, steel or aluminum alloy, and the handrail 1216 can also be made of non-metal materials such as wood or plastic, so that the body 121 has high hardness and strength while having a lighter weight. It should also be noted that the table top 1215 and the handrail 1216 can also be other single or combined materials, and the embodiment of the present application does not limit the specific materials of the table top 1215 and the handrail 1216.

[0077] The bottom end of the fixed ladder 122 is used to support the ground, and the top end of the fixed ladder 122 is connected to the side of the body 121. The fixed ladder 122 has a passage extending from the bottom end to the top end, and the staff can travel from the bottom end of the fixed ladder 122 to the top end of the fixed ladder 122 through the passage. The passage can be a ladder, and when in use, the staff can climb up to reach the top end of the fixed ladder 122; the passage can also be a conveyor belt, and when in use, the staff can stand on it and be conveyed to the top end of the fixed ladder 122. It can be understood that the passage can also be in other forms, which will not be illustrated one by one here. The top end of the fixed ladder 122 is set corresponding to a passage gap 1210, that is, the top end of the fixed ladder 122 is connected to the position of the edge of the table 1215 where the railing 1216 is not set, so as to avoid the staff from being blocked by the railing 1216 when climbing the table 1215 through the fixed ladder 122. Guardrails may be provided on both side edges of the fixed ladder 122 , and the guardrails are used to protect workers who step onto the fixed ladder 122 from falling, thereby improving safety.

[0078] The fixed ladder 122 may include only one straight or curved section, or two or more sections connected by bending. The fixed ladder 122 may be made of wood, or metal such as iron, steel, or aluminum alloy, or non-metal such as hard plastic. It should be noted that the fixed ladder 122 may also be made of other single or combined materials, and the embodiments of the present application do not limit the specific material of the fixed ladder 122.

[0079] In other embodiments, the platform 120 can be raised and lowered. Specifically, the safety device 100 may further include a lifting assembly (not shown in the figure), which is movably arranged on the support assembly 110 in the vertical direction, and the lifting assembly is fixedly connected to the platform 120. When the lifting assembly is raised and lowered along the support assembly 110 in the vertical direction, the lifting assembly drives the platform 120 to be raised and lowered along the support assembly 110 in the vertical direction.

[0080] In some cases, the platform 120 can be raised and lowered in a large range in the vertical direction along the support assembly 110. In this case, the safety device 100 does not need to be provided with a ladder structure similar to the fixed ladder 122 in the previous embodiment, and the worker can board the platform 120 only by driving the platform 120 up and down by the lifting assembly. When in use, the platform 120 is driven by the lifting assembly to descend to the bottom end of the support assembly 110, and after the worker boards the platform 120 and stands firmly and holds on, the platform 120 is driven by the lifting assembly to rise to the middle section of the support assembly 110.

[0081] In some cases, the platform 120 can only be raised and lowered in a small range in the vertical direction along the support assembly 110. In this case, the safety device 100 may also include a stepladder (not shown in the figure), the top of the stepladder is connected to the side of the platform 120, the bottom of the stepladder is used to support the ground, and the stepladder is retractable. When in use, when the vehicle that needs to be climbed is higher, the lifting assembly is turned on to drive the platform 120 to rise appropriately along the support assembly 110, and the stepladder is extended to adapt to the platform 120; when the vehicle that needs to be climbed is lower, the lifting assembly is turned on to drive the platform 120 to descend appropriately along the support assembly 110, and the stepladder is shortened to adapt to the platform 120; after the platform 120 stops rising and the length of the stepladder is determined, the staff can climb onto the platform 120 through the stepladder. By setting up a lifting component, the platform 120 can be lifted and lowered in a small range in the vertical direction along the support component 110, realizing a fine-tuning function in height, so that the safety device 100 can better adapt to vehicles of different models and heights; and a movable ladder is set for staff to board the platform 120. Through the telescopic function of the movable ladder, the movable ladder can change its length during the lifting and lowering process of the platform 120 to adapt to the platform 120.

[0082] Please continue reading Figure 1 The boarding ladder 130 is a climbing structure of the safety device 100, which allows the staff to climb up after climbing onto the platform 120. The boarding ladder 130 is movably connected to the platform 120, and can be connected to the vehicle that needs to be climbed during use, so that the staff can climb from the platform 120 to the top of the vehicle that needs to be climbed.

[0083] The boarding ladder 130 is movably connected to the platform 120. Specifically, the bottom end of the boarding ladder 130 is movably connected to the side wall of the body 121, and the boarding ladder 130 is arranged corresponding to a passage gap 1210, that is, the bottom end of the boarding ladder 130 is connected to the position of the edge of the table 1215 where the railing 1216 is not arranged, so as to avoid being blocked by the railing 1216 when the staff prepares to climb up the vehicle that needs to perform high-altitude operations through the boarding ladder 130. The boarding ladder 130 can be set to correspond to the same passage opening 1210 as the fixed ladder 122, for example, only one passage opening 1210 with a larger width is opened on the main body 121, and the passage opening 1210 is located at the connection between the first side wall 1211 and the second side wall 1212 and covers part of the first side wall 1211 and the second side wall 1212, the fixed ladder 122 is connected to the first side wall 1211, and the boarding ladder 130 is connected to the second side wall 1212; the boarding ladder 130 can also be set to correspond to different passage openings 1210 with the fixed ladder 122, for example, one passage opening 1210 is opened on the third side wall 1213 and the fourth side wall 1214 on the main body 121, the fixed ladder 122 is connected to the third side wall 1213, and the boarding ladder 130 is connected to the fourth side wall 1214.

[0084] It should be noted that, in order to facilitate the staff to climb from the platform 120 to the top of the vehicle that needs to perform the climbing operation, the vehicle needs to be parked on the side of the platform 120 where the boarding ladder 130 is provided, that is, the boarding ladder 130 is connected to the side of the platform 120 close to the vehicle that needs to perform the climbing operation. In this case, if the fixed ladder 122 and the boarding ladder 130 are connected to the same side of the body 121, the fixed ladder 122 will occupy the parking space of the vehicle that needs to perform the climbing operation, that is, occupy the climbing operation space of the staff. Therefore, the fixed ladder 122 needs to be set on any two different side walls of the body 121 with the boarding ladder 130. The fixed ladder 122 and the boarding ladder 130 can be respectively arranged on two adjacent side walls of the main body 121, for example, the fixed ladder 122 is connected to the first side wall 1211 and the boarding ladder 130 is connected to the second side wall 1212; the fixed ladder 122 and the boarding ladder 130 can also be respectively arranged on two opposite side walls of the main body 121, for example, the fixed ladder 122 is connected to the fourth side wall 1214 and the boarding ladder 130 is connected to the second side wall 1212.

[0085] The bottom end of the boarding ladder 130 is rotatably connected to the side of the table top 1215, so that the boarding ladder 130 can rotate relative to the platform 120 with the side where the boarding ladder 130 and the table top 1215 are connected as the axis, so that the boarding ladder 130 can be rotated during use to overlap the top end of the vehicle that needs to perform climbing operations, and can be rotated to be stored against the railing 1216 after use.

[0086] Furthermore, the boarding ladder 130 can also move in parallel in the horizontal direction along the side where the boarding ladder 130 is connected to the table 1215. During use, after the staff climbs onto the platform 120, when they are ready to climb onto the vehicle that needs to be climbed by the boarding ladder 130, if they find that the part of the vehicle that needs to be worked on is far from the position where the boarding ladder 130 and the vehicle overlap, they can move the boarding ladder 130 in the horizontal direction so that the staff can get closer to the part that needs to be worked on after climbing onto the vehicle by the boarding ladder 130.

[0087] The boarding ladder 130 can be a straight ladder with a fixed length, and the safety device 100 can only drive the platform 120 to rise and fall through the lifting assembly to adapt to vehicles of different models and heights. The boarding ladder 130 can also include a first ladder portion 131 and a second ladder portion 132, the first ladder portion 131 is movably connected to the body 121 of the platform 120, and the second ladder portion 132 is movably connected to the first ladder portion 131, so that the boarding ladder 130 can be adjusted in length, so that the safety device 100 can better adapt to vehicles of different models and heights. Specifically, the second ladder portion 132 can be rotatably connected to the first ladder portion 131 through a hinge or other element, so that the second ladder portion 132 can be rotated relative to the first ladder portion 131 to abut against the first ladder portion 131, so that the boarding ladder 130 can be folded in the length direction. The second ladder portion 132 can also be sleeved with the first ladder portion 131, so that the second ladder portion 132 can be telescopic relative to the first ladder portion 131, so that the boarding ladder 130 can be telescopic in the length direction.

[0088] Please continue reading Figure 1 The protection assembly 140 is a protection structure of the safety device 100 and plays a role in protecting the staff. The protection assembly 140 is arranged at the top of the support assembly 110, and the protection assembly 140 includes a suspension rod 143, and the suspension rod 143 can be used to hang a safety rope.

[0089] The protection assembly 140 may further include a first crossbeam 141 and a second crossbeam 142, and a suspension rod 143 is connected between the first crossbeam 141 and the second crossbeam 142. Specifically, one end of the suspension rod 143 is connected to the first crossbeam 141, and the other end of the suspension rod 143 is connected to the second crossbeam 142. In some embodiments, the two ends of the suspension rod 143 are movably connected to the first crossbeam 141 and the second crossbeam 142, respectively, so that the suspension rod 143 can move in parallel along the horizontal direction between the first crossbeam 141 and the second crossbeam 142. In some embodiments, the two ends of the suspension rod 143 are fixedly connected to the first crossbeam 141 and the second crossbeam 142, respectively, so that the suspension rod 143 cannot move relative to the first crossbeam 141 and the second crossbeam 142, but the first crossbeam 141 and the second crossbeam 142 can be telescopically arranged, so that the suspension rod 143 can move in parallel along the horizontal direction driven by the first crossbeam 141 and the second crossbeam 142. In some embodiments, the two ends of the suspension rod 143 are movably connected to the first cross beam 141 and the second cross beam 142 respectively, and the first cross beam 141 and the second cross beam 142 are telescopically arranged, thereby further improving the flexibility of the suspension rod 143. By arranging the suspension rod 143 to be movable in parallel in the horizontal direction, the hanging position of the safety rope can be changed with the specific position of the worker performing the operation on the vehicle during the use of the safety device 100, thereby improving the convenience of using the safety device 100.

[0090] The first crossbeam 141 is connected to the top of the first pillar 111, and the second crossbeam 142 is connected to the top of the second pillar 112, so that the protection assembly 140 is set at the top of the support assembly 110. In some embodiments, the first crossbeam 141 is fixedly connected to the top of the first pillar 111, and the second crossbeam 142 is fixedly connected to the top of the second pillar 112, so that the protection assembly 140 is fixedly set at the top of the support assembly 110. In some embodiments, the first crossbeam 141 is rotatably connected to the top of the first pillar 111, and the second crossbeam 142 is rotatably connected to the top of the second pillar 112, so that the protection assembly 140 can be rotated relative to the support assembly 110 to reach a propped up state or a retracted state. When the protection assembly 140 is in the propped up state, a certain angle is formed between the protection assembly 140 and the support assembly 110, and the safety device 100 forms an operating space below the protection assembly 140 for the vehicle that needs to perform the climbing operation to be parked and perform the climbing operation. When the protection component 140 is in the retracted state, the protection component 140 is stored against the support component 110 .

[0091] It should be noted that during use, the vehicle that needs to perform climbing work drives in and stops beside the support assembly 110. In order to facilitate the staff to hang the safety rope on the suspension rod 143 of the protection assembly 140 when performing the climbing work, the protection assembly 140 should be set on the side of the protection assembly 140 facing the vehicle that needs to perform the climbing work, so that the vehicle that needs to perform the climbing work is parked beside the support assembly 110 and is also located below the protection assembly 140. In order to avoid the platform 120 occupying the space below the protection assembly 140 for the vehicle that needs to perform the climbing work to stop, the platform 120 should be set on the side of the protection assembly 140 facing away from the vehicle that needs to perform the climbing work, and the platform 120 and the protection assembly 140 are respectively located on both sides of the support assembly 110. At the same time, because the boarding ladder 130 is connected to the side of the platform 120 close to the vehicle that needs to perform the climbing work, the boarding ladder 130 and the protection assembly 140 are located on the same side of the support assembly 110.

[0092] In addition, in order to further facilitate the staff to hang the safety rope on the suspension rod 143 of the protection assembly 140 after boarding the boarding ladder 130, the boarding ladder 130 can be set between the first pillar 111 and the second pillar 112, so that the first pillar 111 and the first beam 141 are located on the same side of the boarding ladder 130, and the second pillar 112 and the second beam 142 are located on the other side of the boarding ladder 130, so that the boarding ladder 130 is located directly below the protection assembly 140.

[0093] See also Figure 4 , Figure 4The structure diagram of another embodiment of the safety device of the present application is shown. The safety device 100 may further include a roof 150. The roof 150 is located at the highest point of the safety device 100 in the vertical direction, and is used to shield the space below the roof 150. Specifically, the roof 150 may be mounted on the protection assembly 140. The roof 150 may be a sheet-like structure, and a part of the roof 150 is arranged on the first crossbeam 141, and another part of the roof 150 is arranged on the second crossbeam 142, so that the roof 150 is mounted on the protection assembly 140. The roof 150 may be arranged on the first crossbeam 141 and the second crossbeam 142 by glue bonding, the roof 150 may also be arranged on the first crossbeam 141 and the second crossbeam 142 by screwing, and the roof 150 may also be arranged on the first crossbeam 141 and the second crossbeam 142 by clamping. In order to prevent the weight of the roof 150 from being too heavy and causing the protective assembly 140 to be overloaded, the roof 150 can be made of a relatively light material, such as plastic, acrylic, etc. It should be noted that the roof 150 can also be set on the protective assembly 140 in other ways, and the roof 150 can also be made of other single or combined materials. The embodiment of the application does not limit the specific way in which the roof 150 is set on the protective assembly 140 and the specific material of the roof 150.

[0094] Please also read Figure 1 and Figure 4 The safety device 100 may further include a first reinforcement member 161 and a second reinforcement member 162. The first reinforcement member 161 is connected between the support assembly 110 and the platform 120 to support the platform 120 and thus reinforce the platform 120. The second reinforcement member 162 is connected between the support assembly 110 and the protection assembly 140 to support the protection assembly 140 and thus reinforce the protection assembly 140.

[0095] The number of first reinforcement members 161 is not less than two. Among them, one end of at least one first reinforcement member 161 is fixedly connected to the first pillar 111 and the other end is fixedly connected to the table 1215, and one end of at least one first reinforcement member 161 is fixedly connected to the second pillar 112 and the other end is fixedly connected to the table 1215. The number of second reinforcement members 162 is not less than two. Among them, one end of at least one second reinforcement member 162 is connected to the first pillar 111 and the other end is connected to the first crossbeam 141, and one end of at least one second reinforcement member 162 is connected to the second pillar 112 and the other end is connected to the second crossbeam 142. It should be noted that if the first cross beam 141 is rotatably connected to the top of the first pillar 111 and the second cross beam 142 is rotatably connected to the top of the second pillar 112, so that the protective assembly 140 can rotate relative to the supporting assembly 110, then in order not to hinder the folding of the protective assembly 140, the connection between the second reinforcement 162 and the supporting assembly 110 and / or the connection between the second reinforcement 162 and the protective assembly 140 should be a movable connection so that the second reinforcement 162 can be folded, thereby folding the protective assembly 140.
