Description

Technical Field

[0001] This utility model relates to the field of construction equipment technology, and in particular to a high-altitude construction work platform with a foldable and extendable structure. Background Technology

[0002] There are generally three types of high-altitude work platforms used in construction: scaffolding platforms, suspended platforms, and hoist platforms. Scaffolding platforms are a traditional and widely used type of high-altitude work platform. They are constructed from steel pipes, fasteners, and other components, and can be flexibly assembled into different shapes and heights according to construction needs. Suspended platforms typically consist of a suspension mechanism, a suspended platform body, and a lifting device. They are suspended from the top of the building by steel wire ropes, allowing workers to perform high-altitude operations inside the suspended platform. Hoist platforms mainly rely on hydraulic or electric drive systems to achieve lifting functions. Common types include scissor lifts and flat-arm lifts. Scissor lifts have a compact structure, stable lifting, and can provide high load-bearing capacity, making them suitable for high-altitude operations in relatively fixed locations, such as interior decoration and equipment installation.

[0003] Traditional suspended platforms for high-altitude operations are cumbersome to install and dismantle, and are not conducive to transportation. In addition, loading materials into traditional suspended platforms is difficult and laborious, thus failing to meet people's needs.

[0004] An existing patent (publication number: CN207073273U) discloses a suspended platform for high-altitude construction. In this utility model, the main upright is connected to the fixing screw hole on the fixing plate by the installation screw, and the fixing plate is located at the bottom of the base plate, which makes the installation and disassembly of the device simpler and more convenient, and makes the device easier to carry and transport, thus making the device more practical.

[0005] To address the aforementioned issues, existing patents have provided solutions. However, current aerial work platforms still have significant drawbacks. Firstly, they are typically fixed structures without folding or extending capabilities, making them extremely inconvenient to transport due to their large size, thus increasing transportation costs and difficulties. Secondly, fixed platforms cannot freely adjust the height of the protective frame according to the user's height, making it difficult to meet the safety protection needs of workers of different heights. These shortcomings severely limit their application scenarios and make it difficult to meet the diverse, convenient, and safe requirements of modern construction.

[0006] Therefore, a high-altitude construction platform with a foldable and extendable structure is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a construction aerial work platform with a foldable and extendable structure, which can solve the significant defects of existing aerial work suspended platforms. First, they are usually fixed structures without foldable and extendable functions, which makes them extremely inconvenient to transport due to their large size, increasing transportation costs and difficulties. Second, fixed suspended platforms cannot freely adjust the height of the protective frame according to the user's height, making it difficult to meet the safety protection needs of workers of different heights. These shortcomings seriously limit their application scenarios and make it difficult to meet the diversified, convenient and safe requirements of modern construction.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a construction aerial work platform with a foldable and extendable structure, including a work platform, wherein a foldable and extendable mechanism is provided on the top of the work platform;

[0009] The folding and extending mechanism includes a high block welded to the left side of the work platform. The high block is located at the front and rear sides of the left side of the work platform. A left frame is rotatably connected to the outer side of the high block. Fixed sleeves are rotatably connected to the front and rear sides of the top of the left frame. Low blocks are welded to the front and rear sides of the right side of the work platform. A right frame is rotatably connected to the outer side of the low blocks. Connecting rods are rotatably connected to the front and rear sides of the left side of the right frame. The left side of the connecting rod is engaged with the right side of the bottom of the fixed sleeve. A fixing screw is provided on the front side of the fixed sleeve. The rear side of the fixing screw passes through the front side of the fixed sleeve and the connecting rod in sequence. The rear side of the fixing screw is threaded into the rear side inside the fixed sleeve. Lifting guardrail assemblies are provided on the top of both the left and right frames.

[0010] Preferably, the lifting guardrail assembly includes a fixed rod fixedly connected inside the left frame and the right frame. The fixed rod is internally threaded with an adjusting screw. The top of the left adjusting screw penetrates the top side inside the left frame, and the top of the right adjusting screw penetrates the top side inside the right frame.

[0011] Preferably, a hand-operated plate is fixedly connected to the bottom of the adjusting screw, and a guard rod is rotatably connected to the top of the adjusting screw.

[0012] Preferably, the bottom of the guard rod is fixedly connected to the front and rear sides with sliding rods, the bottom of the left sliding rod passes through the top of the left frame and the left fixed rod in sequence, and the bottom of the right sliding rod passes through the top of the right frame and the right fixed rod in sequence. The inner side of the guard rod is provided with a side protection structure.

[0013] Preferably, the side guard structure includes a sleeve fixedly connected to the inside of the right guard rod, and hidden grooves are provided on the front and rear sides of the inside of the left guard rod.

[0014] Preferably, a side stop bar is rotatably connected inside the hidden groove, and the end of the side stop bar away from the hidden groove is engaged inside the sleeve.

[0015] Preferably, a reinforcing plate is fixedly connected to the bottom of the work platform, and the top of the reinforcing plate is fixedly connected to the bottom of the high block and the low block respectively.

[0016] Preferably, the left frame and the right frame are both fixedly connected to the front and rear sides of the top, and the inside of the hanging sleeve is annular.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application, by setting up a folding and extending mechanism, allows the device to be transported when not in use. First, the fixing screw is unscrewed from the fixing sleeve and connecting rod, releasing the connection between the connecting rod and the fixing sleeve. Since the left frame is rotatably connected to the left side of the work platform via a high block and the right frame is rotatably connected to the right side of the work platform via a low block, the left and right frames can be rotated around the high and low blocks respectively, causing them to fold towards the work platform. During this process, the right frame is located at the bottom of the left frame. Through this operation, the left and right frames can fold closer to each other, greatly reducing the overall volume of the aerial work platform, improving the equipment's transport efficiency, and allowing it to be more flexibly deployed and used in different construction sites. When needed in the future, the above steps are reversed to extend and connect the components.

[0019] 2. By setting up a lifting guardrail component, this application allows workers to flexibly and freely adjust the height of the lifting guardrail component upwards based on their own height, within the predetermined heights of the left and right frames. This design effectively meets the safety protection needs of workers of different heights, significantly improves safety during operation, broadens the applicable population of the platform, and truly meets the diversified, convenient, and safe requirements of modern construction.

[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A construction aerial work platform with a foldable and extendable structure includes a work platform 1, and a foldable and extendable mechanism 2 is provided on the top of the work platform 1.

[0029] The folding and extending mechanism 2 includes a high block 21 welded to the left side of the working platform 1. The high block 21 is located on the front and rear sides of the left side of the working platform 1. A left frame 22 is rotatably connected to the outer side of the high block 21. A fixed sleeve 23 is rotatably connected to the front and rear sides of the top of the left frame 22. A low block 24 is welded to the front and rear sides of the right side of the working platform 1. A right frame 25 is rotatably connected to the outer side of the low block 24. A connecting rod 26 is rotatably connected to the front and rear sides of the left side of the right frame 25. The left side of the connecting rod 26 is engaged with the right side of the bottom of the fixed sleeve 23. A fixing screw 27 is provided on the front side of the fixed sleeve 23. The rear side of the fixing screw 27 passes through the front side of the fixed sleeve 23 and the connecting rod 26 in sequence. The rear side of the fixing screw 27 is threaded into the rear side inside the fixed sleeve 23. A lifting guardrail assembly 28 is provided on the top of both the left frame 22 and the right frame 25.

[0030] In this embodiment: via the folding extension mechanism 2, when the transport device needs to be moved, the fixing screw 27 of the folding extension mechanism 2, as a key control component, can be unscrewed from the fixing sleeve 23 and connecting rod 26 to disconnect them. Based on the rotational connection relationship between the left frame 22 and the high block 21, and the right frame 25 and the low block 24, the left and right frames 25 are rotated around the high block 21 and the low block 24 respectively, causing them to fold towards the working platform 1. The right frame 25 will be located at the bottom of the left frame 22, achieving folding, reducing the size of the device, and facilitating transport. In actual operation, the above steps are reversed to extend and connect the components. Since the top of the left frame 22 and the right frame 25 are equipped with lifting guardrail components 28, workers of different heights can flexibly adjust the height of the lifting guardrail components 28 according to their own situation to make the protection height fit their own needs and ensure work safety. Throughout the entire process, from the folding operation during transport to the guardrail height adjustment during operation, the components work together, which not only solves the problem of handling, but also meets the safety operation needs of different personnel, improving the practicality of the aerial work platform 1.

[0031] Specifically, such as Figure 4 As shown, the lifting guardrail assembly 28 includes a fixed rod 281 fixedly connected inside the left frame 22 and the right frame 25. An adjusting screw 282 is threaded inside the fixed rod 281. The top of the left adjusting screw 282 passes through the top side inside the left frame 22, and the top of the right adjusting screw 282 passes through the top side inside the right frame 25.

[0032] Specifically, such as Figure 4 As shown, a hand-operated plate 283 is fixedly connected to the bottom of the adjusting screw 282, and a guard rod 284 is rotatably connected to the top of the adjusting screw 282.

[0033] Specifically, such as Figure 4 As shown, the bottom of the guard rod 284 is fixedly connected to the front and rear sides of the sliding rod 285. The bottom of the left sliding rod 285 passes through the top of the left frame 22 and the left fixed rod 281 in sequence. The bottom of the right sliding rod 285 passes through the top of the right frame 25 and the right fixed rod 281 in sequence. The inner side of the guard rod 284 is provided with a side protection structure 286.

[0034] In this embodiment: By setting up the lifting guardrail assembly 28, when the operator needs to adjust the height of the guardrail 284, by rotating the hand-operated plate 283 at the bottom of the adjusting screw 282, since the adjusting screw 282 is threadedly connected to the fixed rod 281, rotating the hand-operated plate 283 will cause the adjusting screw 282 to move up or down along the fixed rod 281. The guardrail 284, which is rotatably connected to the top of the adjusting screw 282, will rise and fall with the movement of the adjusting screw 282. The sliding rod 285 at the bottom of the guardrail 284 slides in the corresponding channels of the left frame 22, the right frame 25 and the fixed rod 281, ensuring that the guardrail 284 rises and falls smoothly. In this way, operators of different heights can flexibly adjust the height of the guardrail 284 according to their own needs, so that the protection height fits their own situation, effectively preventing accidental falls during operation and ensuring operational safety. In addition, the side protection structure 286 set inside the guardrail 284 can also be unfolded, making the guardrail 284 as a frame, which provides better protection.

[0035] Specifically, such as Figure 5 As shown, the side guard structure 286 includes a sleeve 2861 fixedly connected to the inside of the right guard rod 284, and a hidden groove 2862 is provided on the front and rear sides of the inside of the left guard rod 284.

[0036] Specifically, such as Figure 5 As shown, a side stop bar 2863 is rotatably connected inside the hidden groove 2862, and the end of the side stop bar 2863 away from the hidden groove 2862 is engaged inside the sleeve 2861.

[0037] In this embodiment: by setting the side guard structure 286, after the height of the guard rod 284 is adjusted, the side stop bar 2863 is rotated out from the hidden groove 2862 of the guard rod 284, so that the end away from the hidden groove 2862 is engaged in the inside of the sleeve 2861. In this way, the guard rods 284 on the left and right sides are connected together, forming a frame-like protective barrier on the top of the work platform 1, which effectively blocks the workers and prevents them from accidentally slipping. This comprehensively improves the safety of the work platform 1 and ensures the safety of the workers when they are on the work platform 1.

[0038] Specifically, such as Figure 1 As shown, a reinforcing plate 3 is fixedly connected to the bottom of the working platform 1, and the top of the reinforcing plate 3 is fixedly connected to the bottom of the high block 21 and the low block 24 respectively.

[0039] Specifically, such as Figure 1 As shown, the front and rear sides of the top of the left frame 22 and the right frame 25 are fixedly connected to the hanging sleeves 4, and the inside of the hanging sleeves 4 is annular.

[0040] In this embodiment: By setting a reinforcing plate 3 and a lifting sleeve 4, the reinforcing plate 3 is fixedly connected to the bottom of the work platform 1 and connected to the bottom of the high block 21 and the low block 24, which enhances the stability of the connection between the work platform 1, the high block 21 and the low block 24. In addition, the annular lifting sleeve 4 set at the top of the left frame 22 and the right frame 25 facilitates the use of hoisting equipment for lifting operations when the work platform 1 is hoisted, used or disassembled, making the handling and installation of the work platform 1 more convenient and efficient, and reducing the difficulty and risk of manual handling.

[0041] Working Principle: During the use of the aerial work platform in construction, if it is necessary to transport the work platform 1 to other construction sites, firstly, unscrew the fixing screw 27 from the fixing sleeve 23 and the connecting rod 26 to disconnect them. Utilizing the rotational connection characteristics of the left frame 22 and the high block 21, and the right frame 25 and the low block 24, rotate the left frame 22 and the right frame 25 around the high block 21 and the low block 24 respectively, so that the right frame 25 is located at the bottom of the left frame 22 and folds towards the work platform 1, completing the platform folding and reducing its volume for easy handling and transportation. When ready to work at the construction site, reverse the folding steps, unfold the left frame 22 and the right frame 25, and connect the fixing sleeve 23 and the connecting rod 26 through the fixing screw 27, so that the work platform 1 returns to the working state. When workers climb onto the work platform 1 to prepare for work, workers of different heights can adjust the height of the guardrail 284 according to their own needs by rotating the hand-operated plate 283 at the bottom of the adjusting screw 282, based on the threaded connection between the adjusting screw 282 and the fixing rod 281. The lead screw 282 moves up and down along the fixed rod 281, causing the top-rotating guard rod 284 to rise and fall. The slide bar 285 at the bottom of the guard rod 284 slides within the corresponding channel, ensuring the smooth raising and lowering of the guard rod 284 to meet the protection height requirements of different personnel. After the height of the guard rod 284 is adjusted, the side protection structure 286 is unfolded, and the side stop bar 2863 in the hidden groove 2862 of the left guard rod 284 is rotated out, so that it is engaged in the retaining sleeve 2861 inside the right guard rod 284. The frame forms a protective barrier, ensuring the safety of workers in all aspects. In addition, the reinforcing plate 3 at the bottom of the work platform 1 connects the work platform 1, the high block 21 and the low block 24, enhancing the overall structural stability and ensuring that the work platform 1 can withstand various loads during operation. The annular lifting sleeve 4 at the top of the left frame 22 and the right frame 25 facilitates the lifting of equipment when the work platform 1 is lifted for use or dismantled, reducing the difficulty and risk of manual handling and improving the convenience and efficiency of handling and installing the work platform 1.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
