Description

Technical Field

[0001] This utility model relates to the field of construction and maintenance platform technology, and in particular to a suspended working platform. Background Technology

[0002] In the process of industrial equipment maintenance or construction, it is often necessary to build work platforms in high-altitude or suspended environments to meet the needs of construction personnel for operation and tool placement.

[0003] In order to achieve safety and reliability, existing technologies typically employ mobile maintenance work platforms that use the ground as a support structure. For example, the ground is fixed and moved by a combination of jacks, positioning pins and wheels. The stability is mainly achieved by the support components under the work platform contacting the ground. Furthermore, the components between the platforms are mostly rigidly fixed, and when they need to be moved, installed or disassembled, they need to be disassembled and welded one by one, which affects work efficiency.

[0004] Therefore, although existing mobile maintenance work platforms are based on ground operations and utilize welding assembly, resulting in high safety, the reliance on tools for assembly and disassembly leads to low assembly efficiency and is time-consuming and labor-intensive. Furthermore, due to their ground-based design, there are height limitations, making them unsuitable for high-altitude suspended environments where ground support cannot meet operational requirements. Utility Model Content

[0010] Furthermore, the width of the iron plate is 25cm to 35cm, and the length of the iron plate is 90cm to 100cm.

[0011] Furthermore, the bolt-type clamp includes a mounting base, a handle bar, a hinge pin, a gantry frame, and a hook body;

[0012] The mounting base is fixed to one end of the first connecting pipe and the outer round pipe, and the hook body is fixed to one end of the second connecting pipe and the inner round pipe.

[0013] A handle rod is hinged to the top of the mounting base, and a hinge pin is pivotally connected to the middle of the handle rod. The open end of the gantry frame is connected to the hinge pin, and the side of the gantry frame away from the hinge pin is hooked to the hook body.

[0014] Furthermore, bolt-type clamps are also installed on the outside of the upper and lower connection points of the single ladder to reinforce the connection of the single ladder.

[0015] Furthermore, a safety buckle is also provided on the inner side of the connection between the upper and lower parts of the single ladder. Two longitudinally adjacent safety buckles are connected by a U-shaped ring to prevent the connection of the single ladder from separating.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, terms such as "horizontal," "vertical," and "sag" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0036] This utility model embodiment provides a suspended work platform, including: a single ladder 1, a suspension hook 2, an outer circular tube 3, an inner circular tube 4, a footboard assembly 5, and a bolt-type clamp 6;

[0037] Several single ladders 1 are connected from top to bottom, and a hanging hook 2 is fixed to the top surface of the top single ladder 1;

[0038] An outer circular tube 3 is horizontally arranged in the middle of one side of the single ladder 1, and an inner circular tube 4 is horizontally arranged in the middle of the other side of the single ladder 1; the tread assembly 5 is sleeved with the outer circular tube 3 and the inner circular tube 4, and the tread assembly 5 is horizontally placed between the two single ladders 1; a bolt-type clamp 6 is provided at the sleeve of the tread assembly 5 with the outer circular tube 3 and the inner circular tube 4 for locking and fixing.

[0039] Specifically, such as Figures 1-4 As shown, several individual ladders 1 are connected by plugging in from top to bottom. At the bottom of each individual ladder 1, a section of pipe with a slightly larger diameter is welded on (e.g.,...). Figure 1 (As shown at the bottom), forming a "male and female head". During assembly, the top of the next single ladder 1 is inserted into the bottom of the previous single ladder 1, with an insertion depth of 1.5 times the diameter of the single ladder tube, ensuring a stable connection. A suspension hook 2 is welded to the top surface of the single ladder 1 at the top. The suspension hook 2 is hook-shaped and directly hooks onto a horizontal bar or lifting ring, preventing accidental slippage. The single ladder 1 plug-in connection method allows the height of the work platform to be flexibly adjusted according to actual work needs. By increasing or decreasing the number of single ladders 1, the height can be changed to adapt to different work scenarios at different heights. The top suspension hook 2 is suspended from a suitable fixed object, eliminating the dependence on ground support and making it suitable for high-altitude and suspended work environments. This improves the versatility and flexibility of the work platform.

[0040] The aforementioned combination of multiple single ladders 1 comprises two sets, arranged opposite each other and suspended from the building by hooks 2. On one side of the single ladder 1, an outer circular tube 3 is welded horizontally and vertically to the middle, while on the other side, an inner circular tube 4 is similarly welded horizontally and vertically to the middle of the single ladder 1. The outer circular tube 3 and the inner circular tube 4 are opposite each other and their axes are at the same horizontal level, with their center distance matching the width of the tread assembly 5. Both ends of the tread assembly 5 are respectively provided with circular tube interfaces adapted to the outer circular tube 3 and the inner circular tube 4. During assembly, one end of the circular tube of the tread assembly 5 is inserted into the outer circular tube 3, and the other end is inserted into the inner circular tube 4, thus connecting the tread assembly 5 with the two single ladders 1. The tread assembly 5 is placed horizontally between the two single ladders 1, providing a horizontal working platform for workers. A bolt-type clamp 6 is installed at the connection point between the tread assembly 5 and the outer and inner circular tubes 3 and 4. After the pedal assembly 5 is fitted, rotate the movable bolt so that it passes through the hole on the clamp and engages with the latch, clamping the fitted part and fixing the latch.

[0041] The outer tube 3 and inner tube 4 facilitate the installation and removal of the pedal assembly 5. The socket connection is quick and accurate, eliminating the need for complex positioning and calibration processes. Simultaneously, it ensures a tight and stable connection, shortening assembly time. Furthermore, the pedal assembly 5 will not wobble or shift during use. During operation of the work platform, the movement of personnel and the placement of tools can exert various external forces, which, relying solely on the socket connection, could lead to loosening. The latch-type clamp 6 provides clamping force to prevent loosening of the connection between the pedal assembly 5 and the single ladder 1.

[0042] In an embodiment of this utility model, the pedal assembly 5 includes an iron plate 501, and a first connecting pipe 502 and a second connecting pipe 503 are provided on both sides of the iron plate 501; the diameter of the first connecting pipe 502 is 38mm to 42mm, the same as that of the outer round pipe 3, and is used to be sleeved on the outside of the inner round pipe 4; the diameter of the second connecting pipe 503 is 20mm to 28mm, the same as that of the inner round pipe 4, and is used to be clamped into the inside of the outer round pipe 3.

[0043] The width of iron plate 501 is 25cm to 35cm, and the length of iron plate 501 is 90cm to 100cm.

[0044] Specifically, the iron plate 501 provides a flat surface for workers to stand and operate. The width is between 25cm and 35cm, and the length of the iron plate 501 is between 90cm and 100cm; preferably, the width is 30cm and the length is 100cm; this can meet the space requirements for workers to move around on it without making the entire work platform too large.

[0045] It should be noted that the 501 iron plates can be spliced ​​together according to actual needs to form work platforms of different lengths, thereby improving the applicability and flexibility of the work platforms.

[0046] The first connecting pipe 502 and the second connecting pipe 503 are fixed to the two sides or the bottom of the iron plate 501 by welding (when at the bottom, the bolt-type clamps 6 are installed on both sides of the connecting pipe). The diameter of the first connecting pipe 502 and the outer round pipe 3 are both 38mm to 42mm, preferably 32mm. During installation, the first connecting pipe 502 is used to fit over the outside of the inner round pipe 4 on the single ladder 1. The diameter of the inner round pipe 4 and the second connecting pipe 503 are both 20mm to 28mm, so the second connecting pipe 503 is used to fit over the inside of the outer round pipe 3 on the single ladder 1. This allows the tread assembly 5 to be connected to the outer round pipe 3 and the inner round pipe 4 on both sides of the single ladder 1.

[0047] The direct connection is for the convenience of installing and removing the pedal assembly 5. During on-site installation, the operator only needs to connect the first connecting pipe 502 and the second connecting pipe 503 to the outer round pipe 3 and the inner round pipe 4 to complete the installation of the pedal assembly 5, without the need for tools or welding.

[0048] In an embodiment of this utility model, the bolt-type clamp 6 includes a mounting base 601, a handle rod 602, a hinge pin 603, a gantry frame 604, and a hook body 605;

[0049] Mounting base 601 is fixed to one end of the first connecting pipe 502 and the outer round pipe 3, and hook body 605 is fixed to one end of the second connecting pipe 503 and the inner round pipe 4;

[0050] A handle rod 602 is hinged to the top of the mounting base 601. A hinge shaft 603 is pivotally connected to the middle of the handle rod 602. The open end of the gantry frame 604 is connected to the hinge shaft 603. The side of the gantry frame 604 away from the hinge shaft 603 is hooked to the hook body 605.

[0051] The bolt-type clamp 6 is also installed on the outside of the upper and lower connection of the single ladder 1 to reinforce the connection of the single ladder 1.

[0052] Specifically, such as Figure 5 As shown, the mounting base 601 is fixed to one end of the first connecting pipe 502 and the outer round pipe 3 by welding or bolting. The clamp's point of action is directly set at the connection between the pedal assembly 5 and the single ladder 1, effectively reinforcing and locking the connection. The hook body 605 is also fixed to one end of the second connecting pipe 503 and the inner round pipe 4 by welding or bolting. The hook body 605 can engage with the portal frame 604. When the portal frame 604 and the hook body 605 are engaged, the pedal assembly 5 and the single ladder 1 are firmly connected together, preventing the connection from loosening due to external forces during operation.

[0053] The top of the mounting base 601 is hinged to a handle rod 602 via a pin or bushing, allowing the handle rod 602 to rotate around the hinge point. A hinge pin 603 is pivotally mounted in the middle of the handle rod 602, connecting to the open end of the gantry frame 604, allowing the gantry frame 604 to move with the rotation of the handle rod 602. When the operator operates the handle rod 602, the rotation is transmitted to the gantry frame 604 via the hinge pin 603, causing the gantry frame 604 to move closer to or further away from the hook body 605.

[0054] In an embodiment of this utility model, a safety buckle 7 is also provided on the inner side of the upper and lower connection of the single ladder 1. Two longitudinally adjacent safety buckles 7 are connected by a U-shaped ring to prevent the connection of the single ladder 1 from separating.

[0055] Safety rope limiting rings 8 are distributed on both sides of the single ladder 1 to fix the safety rope and limit its movement.

[0056] A support frame 9 is installed on the side of the single ladder 1 closest to the wall to control the safe distance between the single ladder 1 and the building.

[0057] Specifically, the safety buckle 7 is fixed to the inside of the single ladder 1 by welding. A U-shaped ring is used to connect two adjacent safety buckles 7 longitudinally (vertically, between two single ladders 1, one above the other). The U-shaped ring has a conventional structure with rotatable bolts at both ends. After passing the U-shaped ring through two adjacent safety buckles 7, the bolts are tightened to connect the two safety buckles 7. During use, the connection of the single ladder 1 may loosen or even separate due to the weight of people and tools, external impacts, etc. The safety buckle 7 and the U-shaped ring are reinforced with an additional layer, improving the safety of the single ladder 1 connection.

[0058] Two safety rope limiting rings 8 are evenly distributed on both sides of the single ladder 1. The safety rope can pass through the safety rope limiting rings 8, and the inner diameter of the safety rope limiting ring 8 is larger than the outer diameter of the safety rope. This ensures that the safety rope can pass freely while also limiting its movement. When working at heights, workers need to wear safety ropes to prevent accidental falls. The safety rope limiting rings 8 ensure that the safety rope is relatively fixed in position on the single ladder 1, preventing it from swinging or slipping.

[0059] A support frame 9 is installed on the side of the single ladder 1 closest to the wall. The support frame 9 is a tripod, a T-shaped frame, or a pad, which prevents the single ladder 1 from being too close to the wall when it is used against the building wall.

[0060] Based on the above embodiments, the specific installation process of the suspended work platform provided by this utility model is as follows:

[0061] Several single ladders 1 are connected from top to bottom to achieve quick connection. The top hook 2 of the top single ladder is directly hooked to the fixed crossbar, hanging ring or the pre-embedded part of the building wall to ensure the stability of the suspension point. The safety buckle 7 on the inside of the single ladder is connected by a U-shaped ring to strengthen the longitudinal connection between the upper and lower single ladders and prevent separation.

[0062] Connect the first connecting pipe 502 and the second connecting pipe 503 at both ends of the pedal assembly 5 to the outer circular pipe 3 and the inner circular pipe 4 of the two single ladders respectively. After alignment, pull the handle rod 602 of the bolt clamp 6 to drive the gantry frame 604 to engage with the hook body 605 and lock the connection. According to the operation requirements, multiple pedal assemblies 5 can be spliced ​​horizontally to extend the platform length, or the number of single ladders 1 can be increased vertically to adjust the height.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
