[0027] The setting of the side platform 2 extends the working range and improves work efficiency and safety. At the same time, the side platform 2 can be used as side protection for the main platform 1 when it is folded. The side platform 2 is multi-purpose, which reduces weight and improves the carrying capacity of the working platform. The design of the folding railing assembly 4 can be used for side protection of the side platform 2 when the side platform 2 is unfolded, and can also be used to lock the side platform 2 when the side platform 2 is folded, realizing dual use, reducing weight and improving the carrying capacity of the working platform.

[0028] In order to ensure the reliability of the folding railing assembly 4, the folding railing assembly 4 includes a folding railing 5 and a fixing lock. When the side platform 2 is in a folded state, the folding railing 5 is used to prevent the side platform 2 from expanding outward, and the fixing lock is used to fix the folding railing 5. When the side platform 2 is in an expanded state, the folding railing 5 is used to connect with the flip guardrail 3 to form side protection of the side platform 2.

[0029] To ensure the reliability of the folding railing assembly 4, one end of the folding railing 5 is rotatably connected to the main platform 1 and the other end is detachably connected to the flip guardrail 3. The fixed lock is a bent plate 6, one end of which is fixedly connected to the main platform 1. A locking groove 7 with an upward opening is formed between the bent plate 6 and the main platform 1, which can accommodate the folding railing 5. The bent plate 6 and folding railing 5 are located on opposite sides of the side platform 2. When the side platform 2 is folded, the folding railing 5 is located outside the side platform 2, which can prevent the side platform 2 from expanding outward. In this embodiment, the bent plate 6 is L-shaped. The folding railing 5 is detachably connected to the flip guardrail 3. When the side platform 2 is folded, the folding railing 5 can be separated from the flip guardrail 3, which is convenient for folding the flip guardrail 3. At the same time, the folding railing 5 can be rotated relative to the main platform 1, which is convenient for locking the folding railing 5 to the side platform 2; the design of the bending plate 6 is convenient for processing and low in cost; the design of the locking groove 7 makes locking simple. You only need to put one end of the folding railing 5 into the locking groove 7. The outward rotation of the folding railing 5 will be restricted by the bending plate 6 to complete the locking.

[0030] For reliable connection, Figure 3 、 Figure 4As shown, the folding railing 5 is rotatably connected to the main platform 1 via a rotating shaft 8; a hook 9 is provided on the flip guardrail 3, and a fixing hole 10 is opened on the folding railing 5, which cooperates with the hook 9; when the folding railing 5 is located at the top of the rotating shaft 8, the bottom surface of the folding railing 5 is higher than the highest point of the hook 9; when the folding railing 5 is located at the bottom of the rotating shaft 8, the top surface of the folding railing 5 is lower than the highest point of the hook 9; a fixing pin 11 is provided on the rotating shaft 8, which is used to prevent the folding railing 5 located at the bottom of the rotating shaft 8 from moving upward along the axial direction of the rotating shaft 8; a rubber pad 12 is provided at the bottom of the side platform 2, and when the side platform 2 is folded and locked, the two sides of the rubber pad 12 respectively abut against the side platform 2 and the folding railing 5. Specifically, a fixing seat 20 is provided on the main platform 1, and the rotating shaft 8 is set on the fixing seat 20; the hook 9 is L-shaped; the fixing hole 10 is a waist hole, which is convenient for connection with the hook 9; the folding railing 5 and the bending plate 6 are provided in two groups, and the two groups are arranged in opposite directions. The design of the fixing hole 10 and the hanging ear 9 makes it easy to connect the folding railing 5 and the flip guardrail 3.

[0031] To ensure reliable support for the side platforms 2 after they are deployed, a first connector is provided between the main platform 1 and the side platforms 2. The first connector is used to support the side platforms 2 and flexibly connects the main platform 1 and the side platforms 2. When the side platforms 2 are deployed, the first connector can suspend the side platforms 2, increasing their load-bearing capacity and controlling their tilting angle.

[0032] In order to ensure the reliability of the first connecting member, the first connecting member is a first chain 13, one end of the first chain 13 is connected to the main platform 1, and the other end is connected to the side platform 2; the first chain 13 and the side platform 2 are connected by a shackle 14, one end of the shackle 14 is connected to the side platform 2, and the other end is connected to the first chain 13; a lifting ring 15 is provided on the main platform 1, and a movable lock buckle 16 is provided at the end of the first chain 13 away from the shackle 14, and the movable lock buckle 16 is connected to the lifting ring 15. In this embodiment, the first chain 13 is arranged on both sides of the side platform 2; of course, the first chain 13 can also be replaced by a rope. The design of the first chain 13 has high structural strength and good support; the design of the movable lock buckle 16 allows the movable lock buckle 16 to be detached from the lifting ring 15 after the side platform 2 is folded, and the first chain 13 can be hung on the main platform 1.

[0033] In order to expand the standing area, two side platforms 2 are provided; the two side platforms 2 are arranged symmetrically relative to the main platform 1.

[0034] In order to facilitate installation, a quick-release latch 21 is provided on the main platform 1. Figure 5As shown, a mechanical gripper 22 is provided on the robotic arm, and a quick-release latch 21 is connected to the mechanical gripper 22.

The clamp base 24 has a through hole 25 that cooperates with the quick-release latch 21.

[0035] To ensure the side platforms 2 can be retracted securely, the main platform 1 is provided with fixed stoppers 19, which are used to limit the position of the side platforms 2. When the side platforms 2 are retracted, the surface of the side platforms 2 facing the main platform 1 abuts against the fixed stoppers 19. The fixed stoppers 19 cooperate with the folding rails 5 to prevent the side platforms 2 from tilting inward or outward, ensuring that the side platforms 2 can be retracted securely.

[0036] To unfold the side platform 2, first pull out the fixing pin 11 on the rotating shaft 8, move the folding railing 5 upward along the axial direction of the rotating shaft 8, so that the folding railing 5 disengages the locking groove 7, and then rotate the folding railing 5 outward to unlock the side platform 2. At the same time, buckle the movable lock buckle 16 into the lifting ring 15, rotate the side platform 2 outward, flip the guardrail 3 relative to the side platform 2 and unfold it, insert the fixing hole 10 on the folding railing 5 into the hanging ear 9 to fix the flip guardrail 3, and finally insert the fixing pin 11 back into the rotating shaft 8 to complete the unfolding of the side platform 2.

[0037] To fold the side platform 2, first pull out the fixing pin 11 on the rotating shaft 8, move the folding railing 5 upward along the axial direction of the rotating shaft 8, so that the fixing hole 10 on the folding railing 5 is disengaged from the hanging ear 9, and rotate the side platform 2 inward. The flip guardrail 3 will flip and fold relative to the side platform 2 until the side platform 2 abuts against the fixed stop lock 19, rotate the folding railing 5 inward, and snap the folding railing 5 into the locking groove 7 to lock the side platform 2. Finally, insert the fixing pin 11 back onto the rotating shaft 8 to complete the folding of the side platform 2.

[0040] The intermediate support platform 17 can be flipped and folded, or it can be folded without flipping and folding. In the folded state, it does not take up extra space and can enhance the protection of the side of the main platform 1. In the unfolded state, the intermediate support platform 17 is higher than the main platform 1, which can increase the standing height of the personnel and solve the problem that when the arch frame is installed, the distance between the personnel and the arch frame is too large and they cannot work.

[0041] In order to ensure reliable support for the intermediate support platform 17 after it is unfolded, a second connecting member is provided between the intermediate support platform 17 and the main platform 1, and the second connecting member is used to support the intermediate support platform 17; the second connecting member flexibly connects the intermediate support platform 17 and the main platform 1; the second connecting member is a second chain 18, one end of the second chain 18 is connected to the intermediate support platform 17, and the other end is connected to the main platform 1. In this embodiment, the second chain 18 is set on both sides of the intermediate support platform 17; of course, the second chain 18 can also be replaced by a rope. When the intermediate support platform 17 is in the unfolded state, the second chain 18 can suspend the intermediate support platform 17, increase the bearing capacity of the intermediate support platform 17, and control the flipping angle of the intermediate support platform 17; the design of the second chain 18 has high structural strength and good support.

[0042] In order to increase the range of activities, a side platform is also included; the side platform is the side platform 2 in the foldable working platform device described in Example 1.
