[0021] The utility model will be further described in detail in combination with the drawings and examples.
[0022] For example, Figure 1 and Figure 2The utility model discloses a kind of hidden rail for aerial work platform, including rail body 1 and the fixed support 3 being connected with rail body 1, wherein, rail body 1 is movably connected with fixed support 3, to realize that rail body 1 can be laid down, impact panel 2 is equipped on rail body 1, rail body 1 includes multiple posts 11 and handrail 12 being connected on post 11, post 11 and handrail 12 are welded fixed, the number of fixed support 3 is same with the number of post 11, the lower end of post 11 is movably connected with fixed support 3, impact panel 2 is arranged between two posts 11 and is connected with it.
[0023] As Figure 1 And Figure 2 Indicated, rail body 1 is by multiple frame structures, i.e. two posts 11 and an handrail 12 between each frame structure are welded, form an n-shaped, impact panel 2 is fixed in it, connect and fix together with impact panel 2 between two two frame structures after splicing multiple frame structures (( Figure 6 Indicated), rail body 1 is made of stainless steel material, post 11 and handrail 12 are all board-like strip structure, and the both ends of handrail 12 are spliced and welded fixed with the upper end of post 11 respectively.
[0024] As Figure 1 、 Figure 2 And Figure 5 Indicated, fixed support 3 includes back patch 32, support piece 31, back patch 32 is equipped with through-hole being connected and fixed with chemical anchor bolt, back patch 32 is fixed with platform structure layer through chemical anchor bolt, support piece 31 is equipped with two, and it is board-like structure, is made of stainless steel material, support piece 31 is symmetrically arranged on back patch 32, is fixed with back patch 32 by welding mode, gap is equipped between two support pieces 31, post 11 is inserted into gap, and at least two first bolt hole 311 are equipped on support piece 31, two first bolt hole 311 are horizontally arranged, and two second bolt hole 111 are equipped with corresponding two first bolt hole 311 at the lower end of post 11, and bolt 4 is arranged in two first bolt hole 311 and corresponding second bolt hole 111, bolt 4 is inserted into first bolt hole 311 and second bolt hole 111, so that post 11 is relatively fixed with support piece 31, and at least one bolt 4 is detachable, by detaching detachable bolt 4, rail body 1 is laid down, realizes that rail body 1 does not completely separate with fixed support 3 while being laid down, realizes that rail is quickly laid down in the case of not completely detaching.
[0025] As Figure 5 、 Figure 6 And Figure 7 As shown, the pin 4 is equipped with a pin lock 5, which passes through the pin body of the pin 4. Specifically, one end of the pin 4 has a flat head 41 that protrudes outwards, and the end of the pin 4 away from the flat head 41 has a through hole 42. The pin lock 5 is inserted into the through hole 42, which is perpendicular to the axis of the pin 4, so as to limit the pin 4 to the fixed support 3. The two pins can securely fix the railing body 1 to the fixed support 3. This ensures that the column 11 is perpendicular to the fixed support 3 and can be laid down in two directions. The bolt lock 5 is made of bent steel strip and has a lifting ring. The two ends of the lifting ring are connected to two pins respectively. A bent limiting foot is provided at the end of the pin away from the lifting ring. When subjected to external force, the limiting foot can be pressed to be nearly straight with the pin and then inserted into the through hole 42. The limiting foot returns to its original position after the external force is lost, so that the bolt lock 5, the lifting ring and the bolt lock 5 are restricted in the through hole 42 and cannot be dislodged.
[0026] Optionally, both pins 4 are detachable. In use, depending on the direction of folding, after pulling out the pin lock 5 on the pin 4 in the opposite direction, the pin 4 is pulled out again, so that the railing body 1 can be folded down.
[0027] like Figure 1 , Figure 2 and 6 As shown, the anti-collision panel 2 includes an outer frame 22 and a mesh panel 21. The mesh panel 21 is welded and fixed in the outer frame 22. The outer frame 22 is connected and fixed to the column, which is a frame structure, by bolts. Of course, the column is provided with holes for the bolts to pass through. The mesh panel 21 is made of aluminum textured mesh.
[0028] The construction process of this utility model is as follows: the support member 31 is fixed to the post-embedded plate 32 by welding, and the post-embedded plate 32 is fixed to the platform structure layer by chemical anchors to ensure the stability of the structure. The frame structure of the railing is composed of columns 11 and handrails 12 welded together. The mesh plate 21 is welded into the outer frame 22 to form the anti-collision panel 2, and is fixed to the columns 12 with stainless steel bolts. The railing body 1 is connected to the fixed support 3 using a detachable pin 4. Finally, the railing body 1 is fixed in place by a pin 5 to ensure stability and safety. Figure 3 (As shown). When it is necessary to lower the railing, loosen one of the pins 5 to release the railing body from the fixed support 3. Remove the detachable pin 4 to separate the railing body from the fixed support. Carefully lower the railing, ensuring the process is smooth. Figure 4 (As shown). Re-erect the railing body to its original position, insert the detachable pin 4, use the pin 5 to re-secure the railing, and check the stability of each connection point.
