Description

Technical Field

[0001] This utility model relates to the field of suspended platform structures, and in particular to an arched trolley telescopic suspended platform structure. Background Technology

[0002] In the construction industry, arch frame trolleys are commonly used construction auxiliary equipment, and their accompanying suspended platform structures play a crucial role in enabling construction workers to operate at heights. Telescopic suspended platform structures are designed to meet the needs of flexible adjustment of the platform's size and position in different construction scenarios, thereby improving construction efficiency and operational safety. This type of telescopic suspended platform structure can easily change its extension state according to specific construction conditions, thus better adapting to the working environment around the arch frame trolley and providing construction workers with a stable and suitable working platform.

[0003] Most existing arch frame trolleys are equipped with suspended platform structures that employ relatively traditional fixed-size or simple splicing designs. In terms of mechanical structure, they typically consist of a relatively fixed frame and platform. The frame is connected and fixed to the trolley body, while the platform is directly built onto the frame, resulting in a relatively rigid overall structure. Their technical principle is mainly based on simple mechanical connections and supports, using bolts, welding, and other methods to firmly assemble the various components together, ensuring they can withstand the weight of construction personnel and tools during normal use.

[0004] However, this traditional suspended platform structure has significant problems. During construction, when the size of the suspended platform needs to be adjusted, i.e., when the platform components need to be moved, the lack of effective friction-reducing design results in extremely high friction between the platform components and the supporting structure. This excessive friction makes moving the platform components require a large amount of manpower and time. Therefore, an arch-frame trolley telescopic suspended platform structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an arched trolley telescopic suspended platform structure, which aims to improve the problem of excessive friction and difficulty in movement of the suspended platform components during the sliding process in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A telescopic suspended platform structure with an arched frame includes a welded suspended platform body. The welded suspended platform body includes a support frame. A footboard is fixedly connected to the bottom of the support frame. A slide rail is provided inside the support frame. A fixing frame is fixedly connected to the upper surface of the support frame. A right platform assembly of the suspended platform is slidably connected inside the support frame. A left platform assembly of the suspended platform is slidably connected inside the right platform assembly. A chain assembly is fixedly connected to the side wall of the fixing frame. A fixing assembly is provided on the side wall of the left platform assembly welded to the suspended platform body.

[0008] The left platform assembly of the suspended platform includes a connecting frame one, a roller one is provided inside the connecting frame one, a connecting frame one is fixedly connected to the upper surface of the connecting frame one, and a connecting plate is fixedly connected to the upper surface of the connecting frame one. The right platform assembly of the suspended platform includes a connecting frame two, a roller two is provided inside the connecting frame two, a connecting frame two is fixedly connected to the upper surface of the connecting frame two, and a fixing block two is fixedly connected to the side wall of both the connecting frame one and the connecting frame two.

[0009] As a further description of the above technical solution:

[0010] The fixing component includes a rotating rod, the side wall of which is rotatably connected to the inside of the connecting plate, and a fixing block is fixedly connected to one side wall of the connecting plate.

[0011] As a further description of the above technical solution:

[0012] A fixing plate is fixedly connected to the side wall of the rotating rod, an insert rod is slidably connected inside the fixing plate, and a fixing column is fixedly connected inside the fixing plate.

[0013] As a further description of the above technical solution:

[0014] The side wall of the insertion rod is slidably connected inside the fixing block, and the side wall of the insertion rod is provided with a limit block;

[0015] As a further description of the above technical solution:

[0016] A spring is fitted on the side wall of the insertion rod. One end of the spring is fixedly connected to the inside of the fixing plate, and the other end of the spring is fixedly connected to the side wall of the limiting block.

[0017] As a further description of the above technical solution:

[0018] The insertion rod on the side wall of the fixing frame is slidably connected inside the second fixing block;

[0019] As a further description of the above technical solution:

[0020] Both the first and second connecting frames are fixedly connected to a fixing ring on their side walls, and the side wall of the chain assembly is slidably connected inside the fixing ring.

[0021] As a further description of the above technical solution:

[0022] The first roller and the second roller are arranged in a configuration where there are rollers on all four sides.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, pulling the first connecting frame pulls out the first connecting frame, and pulling the second connecting frame pulls out the second connecting frame. The first and second rollers are arranged in all directions, and the rolling friction generated by the contact of the internal slide rails of the support frame is small, so the left platform component and the right platform component of the suspended basket can be easily slid. This solves the problem that the platform components of the suspended basket are difficult to move due to excessive friction during the sliding process. With the above technical solution, the operator does not need to spend a lot of effort to overcome resistance to move the platform components, which simplifies the operation steps and reduces the labor intensity.

[0025] 2. In this utility model, pulling the insert rod away from the fixed block causes the spring to be squeezed during movement. Rotating the insert rod locks the side wall limiting block against the side wall of the fixed column to prevent the spring from rebounding. Turning the unfixed rotating rod to one side facilitates the entry of workers. This solves the problem of wasting time due to structural adjustments and inconvenience in personnel entry and exit. The above technical solution improves the convenience of personnel entry and exit during the entire construction process, thereby improving construction efficiency. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Reference Figure 1 - Figure 7 This utility model provides an embodiment of an arched trolley telescopic suspended platform structure, comprising a suspended platform body welded 4, the suspended platform body welded 4 including a support frame 6, a footboard 1 fixedly connected to the bottom of the support frame 6, a slide rail provided inside the support frame 6, a fixing frame 7 fixedly connected to the upper surface of the support frame 6, a right platform assembly 5 of the suspended platform slidably connected inside the support frame 6, a left platform assembly 3 of the suspended platform slidably connected inside the right platform assembly 5, a chain assembly 2 fixedly connected to the side wall of the fixing frame 7, the chain assembly 2 being used to pull the left platform assembly 3 and the right platform assembly 5 of the suspended platform, and a fixing assembly being provided on the side wall of the left platform assembly 3 and the suspended platform body welded 4. The left platform assembly 3 of the suspended basket includes a connecting frame 8, inside which a roller 9 is provided, and a connecting frame 10 is fixedly connected to the upper surface of the connecting frame 8. A connecting plate 18 is fixedly connected to the upper surface of the connecting frame 10. The right platform assembly 5 of the suspended basket includes a connecting frame 20, inside which a roller 21 is provided. The roller 9 and the roller 21 are used to reduce the friction when moving inside the slide. A connecting frame 22 is fixedly connected to the upper surface of the connecting frame 20. A fixing block 29 is fixedly connected to the side wall of both the connecting frame 10 and the connecting frame 20. The roller 9 and the roller 21 are arranged in a way that there are rollers in the top, bottom, left and right.

[0037] During construction, the insert rod 14 is pulled. Insert rod 14 is a key component in the fixing assembly; it was originally inserted into fixing block 19 to secure the structure. After removing its fixation of fixing block 19, connecting bracket 10 is pulled to remove connecting frame 8, which provides installation space for roller 9. Next, connecting bracket 22 is pulled to remove connecting frame 20, which serves as the mounting carrier for roller 21. Rollers 9 and 21 are arranged vertically and horizontally. This design ensures that the force is evenly distributed in all directions, guaranteeing stability when moving in different directions. Because the rollers contact the slide rails inside the support frame 6, the contact method between the rollers and the slide rails greatly reduces friction. This low friction significantly reduces the force required by the operator when pulling the connecting frame 10 and the connecting frame 22. Therefore, the left platform assembly 3 and the right platform assembly 5 of the suspended platform can be easily slid. This sliding operation allows for convenient adjustment of the size and position of the suspended platform to adapt to different needs during construction, improving construction efficiency and convenience.

[0038] Reference Figure 1 - Figure 7 The fixing assembly includes a rotating rod 11, the side wall of which is rotatably connected to the inside of a connecting plate 18. A fixing block 12 is fixedly connected to the side wall of one side of the connecting plate 18. A fixing plate 13 is fixedly connected to the side wall of the rotating rod 11. An insert rod 14 is slidably connected inside the fixing plate 13. A fixing post 16 is fixedly connected inside the fixing plate 13. The fixing post 16 is used to limit the reverse movement of the insert rod 14 under the elastic force of the spring 15. The side wall of the insert rod 14 is slidably connected to the inside of the fixing block 12. A limit block is provided on the side wall of the insert rod 14. A spring 15 is sleeved on the side wall of the insert rod 14. The spring 15 is used for rebound and reset. One end of the spring 15 is fixedly connected to the inside of the fixing plate 13. The other end of the spring 15 is fixedly connected to the side wall of the limit block. The insert rod 14 is slidably connected to the inside of a fixing block 19 on the side wall of the fixing frame 7. A fixing ring 17 is fixedly connected to the side walls of both the connecting frame 10 and the connecting frame 22. The fixing ring 17 is used to connect the chain assembly 2. The side wall of the chain assembly 2 is slidably connected to the inside of the fixing ring 17.

[0039] After the left platform assembly 3 and the right platform assembly 5 of the suspended platform slide outwards, the fixing ring 17 is secured by the chain assembly 2. The chain assembly 2 serves as a connection and load-bearing component, capable of supporting the weight of the left platform assembly 3 and the right platform assembly 5 after they slide outwards, ensuring the stability of the entire structure during subsequent operations. The insert rod 14 on the side wall of the fixing frame 7 is inserted into the fixing block 2 19 to fix the left platform assembly 3 and the right platform assembly 5. Insertion into the fixing block 2 19 effectively restricts further movement of the left platform assembly 3 and the right platform assembly 5, thus ensuring their stability in the working state. Then, the insert rod 14 is pulled to move it out of the fixing block 1 12. This movement of the insert rod 14 is to change the current fixed state. During the movement of the insertion rod 14, it compresses the spring 15, which plays a role in elastic support and reset. When the insertion rod 14 moves, the spring 15 is compressed and stores elastic potential energy. When the insertion rod 14 is rotated, the limiting block on the side wall is locked onto the side wall of the fixed column 16 to prevent the spring 15 from rebounding. The limiting block and the fixed column 16 work together. The limiting block restricts the reverse movement of the insertion rod 14 under the elastic force of the spring 15 by locking onto the side wall of the fixed column 16, thereby keeping the spring 15 in a compressed state. Then, the rotating rod 11, which has lost its fixation, is turned to one side. The rotation operation of the rotating rod 11 can change its position in the whole structure. After turning it to one side, space is freed up, making it convenient for workers to enter and ensuring that workers can reach the construction position smoothly to carry out work, thus improving work efficiency and convenience.

[0040] Working principle: During construction, pull the plug rod 14 to release its fixation on the second fixed block 19, then pull the first connecting frame 10 to pull out the first connecting frame 8, and then pull the second connecting frame 22 to pull out the second connecting frame 20. The first connecting frame 8 is equipped with a first roller 9, and the second connecting frame 20 is equipped with a second roller 21. The first roller 9 and the second roller 21 are arranged in all directions. Since the rollers are in contact with the slide rails inside the support frame 6, the rolling friction is very small, so the left platform assembly 3 and the right platform assembly 5 of the suspended platform can be slid easily.

[0041] After the left platform assembly 3 and the right platform assembly 5 of the suspended platform slide out to both sides, the fixing ring 17 is fastened by the chain assembly 2, so that the chain assembly 2 bears the force. Then, the insert rod 14 on the side wall of the fixing frame 7 is inserted into the fixing block 2 19 to fix the left platform assembly 3 and the right platform assembly 5 of the suspended platform. Then, the insert rod 14 is pulled to move it out of the fixing block 1 12. During the movement of the insert rod 14, the spring 15 is squeezed. The insert rod 14 is rotated to lock the limiting block on the side wall into the side wall of the fixing column 16 to prevent the spring 15 from rebounding. Then, the rotating rod 11, which is no longer fixed, is turned to one side to facilitate the entry of the staff.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
