Description

Technical Field

[0001] This utility model relates to the field of suspended platform technology, and in particular to an expandable suspended platform for high-altitude operations. Background Technology

[0002] A suspended platform is a type of lifting equipment widely used in construction, high-altitude operations, disaster relief, and other fields. In existing high-altitude operation solutions, suspended platforms are typically used to elevate workers to higher positions, preventing the risk of falls.

[0003] The existing suspended platforms for high-altitude operations are fixed and cannot be expanded. When it is necessary to lift multiple workers or carry a lot of materials required for high-altitude operations, they will hinder the working space and cause certain safety hazards. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing aerial work platforms, which are fixed and cannot expand their internal space, and to propose an expandable aerial work platform.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An expandable aerial work platform includes a base plate with a through groove between its two ends. Extension plates are slidably inserted into both ends of the groove. A motor is fixedly connected to one side of the base plate, and a double-ended lead screw is keyed to the motor's output end. A first slider and a second slider are threaded onto both ends of the double-ended lead screw, respectively. The first and second sliders slide within the groove. A first connecting rod is rotatably connected to both ends of the first slider, with the other end of the first connecting rod rotatably connected to one end of the extension plate. A second connecting rod is rotatably connected to both ends of the second slider, with the other end of the second connecting rod rotatably connected to one end of the extension plate. First guardrails are fixedly connected to both sides of the top of the base plate, and a second guardrail is fixedly connected to the top of the extension plate. The first and second guardrails are slidably inserted into each other.

[0007] Furthermore, the top of the base plate is fixedly connected with multiple reinforcing ribs.

[0008] Furthermore, an anti-slip pad is adhered to the top of the base plate.

[0009] Furthermore, both ends of the base plate are fixedly connected with inclined blocks.

[0010] Furthermore, a hanging ring is fixedly connected to the top of the first guardrail.

[0011] Furthermore, the bottom inner wall of the chute is provided with a guide groove.

[0012] Furthermore, two guide blocks are fixedly connected to the bottom of the extension plate, and the guide blocks are slidably connected to the guide groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. Driven by the motor, the bidirectional lead screw rotates, thereby driving the first and second sliders to move within the slide groove. This causes the first and second connecting rods to rotate, which in turn pushes the extension plate to move within the slide groove, thereby adjusting the extension plate's length and thus adjusting the space of the aerial work platform to avoid hindering the workers' construction.

[0015] 2. The extension plate drives the second guardrail to move, thereby adjusting the length of the connection between the second guardrail and the first guardrail, so as to adjust the protective space according to the space of the high-altitude work scaffold.

[0016] 3. By sliding the guide block and guide groove together, the movement of the extension plate is guided, thereby improving the stability of the extension plate adjustment. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3An expandable aerial work platform includes a base plate 1 with a through groove between its two ends. Extension plates 5 are slidably inserted into both ends of the groove. A motor 10 is bolted to one side of the base plate 1. A bidirectional lead screw 2 is keyed to the output end of the motor 10. A first slider 3 and a second slider 6 are threaded onto both ends of the bidirectional lead screw 2, respectively. The first slider 3 and the second slider 6 slide within the groove. A first connecting rod 4 is rotatably connected to both ends of the first slider 3, and the other end of the first connecting rod 4 is rotatably connected to one end of the extension plate 5. A second connecting rod 7 is rotatably connected to both ends of the second slider 6, and the other end of the second connecting rod 7 is connected to one end of the extension plate 5. The end is rotated. Driven by the motor 10, the bidirectional lead screw 2 rotates, thereby driving the first slider 3 and the second slider 6 to move in the slide groove. This causes the first connecting rod 4 and the second connecting rod 7 to rotate, thus pushing the extension plate 5 to move in the slide groove. This adjusts the length of the extension plate 5, thereby adjusting the space of the aerial work platform. The top of the base plate 1 has first guardrails 8 welded on both sides, and the top of the extension plate 5 has a second guardrail 9 welded on. The first guardrail 8 and the second guardrail 9 are slidably connected. The extension plate 5 drives the second guardrail 9 to move, thereby adjusting the length of the connection between the second guardrail 9 and the first guardrail 8, so as to adjust the protective space according to the space of the aerial work platform.

[0023] Multiple reinforcing ribs 11 are welded to the top of the base plate 1 to enhance its sturdiness. An anti-slip pad 12 is adhered to the top of the base plate 1. The design of the anti-slip pad 12 increases the friction between the foot and the base plate 1, thereby preventing workers from slipping. Inclined blocks 13 are welded to both ends of the base plate 1. A lifting ring 14 is welded to the top of the first guardrail 8 so that a steel wire rope can be passed through the lifting ring 14 to suspend the high-altitude work basket. A guide groove 15 is provided on the bottom inner wall of the chute. Two guide blocks 16 are welded to the bottom of the extension plate 5. The guide blocks 16 are slidably connected to the guide groove 15 to guide the movement of the extension plate 5 and improve the stability of the adjustment of the extension plate 5.

[0024] Working principle: In use, firstly, the steel wire rope is passed through the lifting ring 14 to suspend the aerial work platform on the hoist. Then, the motor 10 is started, and the double-headed screw 2 rotates under the drive of the motor 10, thereby driving the first slider 3 and the second slider 6 to move in the slide groove. This causes the first connecting rod 4 and the second connecting rod 7 to rotate, thus pushing the extension plate 5 to move in the slide groove, thereby adjusting the extension length of the extension plate 5 and thus adjusting the space of the aerial work platform. At the same time, the extension plate 5 drives the second guardrail 9 to move, thereby adjusting the length of the connection between the second guardrail 9 and the first guardrail 8, so as to adjust the protective space according to the space of the aerial work platform. Then, the first guardrail 8 and the second guardrail 9 protect the workers and prevent them from falling.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
