[0004] However, when the work platform is set too high, it often shakes, which not only affects work efficiency but, more importantly, poses a serious threat to the safety of the workers. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a high-altitude suspended work platform, which solves the problem that serious shaking often occurs when the work platform is set too high.

[0006] According to an embodiment of this utility model, a high-altitude suspended work platform includes a lifting vehicle, a lifting platform, and a lifting mechanism disposed on the lifting platform.

Since the construction platform is connected to the extension arm, when the platform is subjected to force and shakes, the force can be transmitted to the top of the floor through the extension arm, and the building structure can bear part of the external force, effectively reducing the shaking of the construction platform. At the same time, when the extension arm extends to abut against the top of the floor, the construction platform will be more stable when rising.

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] like Figures 1 to 4 As shown in the figure, this utility model embodiment proposes a high-altitude suspended work platform, which includes a lifting vehicle, including a lifting platform 1 and a lifting mechanism 100 disposed on the lifting platform 1. A construction platform 2 is disposed on the upper end of the lifting mechanism 100; an anti-sway unit, including a gantry frame 3 disposed on the lifting platform 1, two extension arms 4 with one end movably disposed in the gantry frame 3, two studs 302 rotatably disposed in the gantry frame 3, and two sets of connectors disposed on the construction platform 2 for connecting the corresponding extension arms 4, wherein each extension arm 4 is threadedly connected to the corresponding stud 302, and each extension arm 4 can extend along the length direction of the gantry frame 3; a drive unit, disposed on the lifting platform 1, is connected to the corresponding stud 302 for driving the stud 302 to rotate.

[0022] The detailed working process of this embodiment is as follows: the drive unit drives the stud 302 to rotate, thereby driving the extension arm 4 to extend upward to abut against the top of the floor, so that the extension arm 4 and the gantry 3 cooperate to form a whole, establishing a direct support connection between the construction platform 2 and the top of the floor, forming a pillar. The construction platform 2 is connected to the extension arm 4. When the platform is subjected to force and shakes, the force can be transmitted to the top of the floor through the extension arm 4, and the building structure can bear part of the external force, which can effectively reduce the shaking of the construction platform 2. At the same time, when the extension arm 4 extends to abut against the top of the floor, the construction platform 2 will be more stable when rising.

[0023] like Figure 3 As shown, the gantry frame 3 has two storage slots 301. Each stud 302 and one end of the extension arm 4 are respectively movably disposed in the corresponding storage slot 301. One end of each stud 302 is threadedly connected to the corresponding extension arm 4, and the other end is rotatably disposed on the lifting platform 1.

[0024] The detailed working process of this embodiment is as follows: A storage slot 301 is opened on the gantry frame 3, which allows a portion of the extension arm 4 to be stored in the slot when not in use. This makes the entire aerial work platform more compact in non-working state or during transportation, reducing space occupation and facilitating equipment storage and transportation. The threaded connection between the extension arm 4 and the stud 302 ensures a tight connection between the stud 302 and the extension arm 4. When transmitting support force, the force can be evenly and stably transmitted from the extension arm 4 to the stud 302, and then to the lifting platform 1 through the stud 302. When the platform is subjected to external force and shakes, the reaction force borne by the extension arm 4 can be reliably transmitted to the entire support structure through the threaded connection, ensuring the stability of the platform. To avoid the stud 302 being subjected to compressive force during rotation, a bearing capable of withstanding axial force can be installed at the connection end between the stud 302 and the lifting platform 1 to ensure the stability of the stud 302.

[0025] like Figure 3 and Figure 4 As shown, the drive unit includes a transmission shaft 303 and an operating shaft 304 rotatably mounted on the lifting platform 1. The transmission shaft 303 has a second helical gear 3030 at both ends, the two studs 302 have a first helical gear 3020 at the end near the lifting platform 1, and the operating shaft 304 has a third helical gear 3040 at one end. Each first helical gear 3020 meshes with a corresponding second helical gear 3030, and the third helical gear 3040 meshes with any first helical gear 3020.

[0026] The detailed working process of this embodiment is as follows: by rotating the operating shaft 304, the operating shaft 304 drives the third helical gear 3040 to rotate, the third helical gear 3040 drives the first helical gear 3020 meshing with it to rotate, and when the first helical gear 3020 rotates, the transmission shaft 303 rotates, thereby driving the two studs 302 to rotate by rotating the operating shaft 304. The thread direction of the two studs 302 is selected according to actual needs to ensure that they rotate synchronously, which can drive the corresponding extension arm 4 to move synchronously.

[0027] like Figure 2 As shown, each connector includes a limiting arm 202 located on one side of the upper end of the construction platform 2, and a roller 203 rotatably mounted on the limiting arm 202.

[0028] like Figure 2 As shown, each of the extension arms 4 has a T-slot 404 on the side away from each other, and each roller 203 is located in the corresponding T-slot 404.

[0029] The detailed working process of this embodiment is as follows: With the setting of the limiting arm 202 and the roller 203, the construction platform 2 rises and falls along the T-slot 404 in the extension arm 4 when it rises. The roller 203 can contact and roll with the surface of the T-slot 404. Compared with direct sliding friction, rolling friction has less resistance, making the construction platform 2 move more smoothly.

[0030] like Figure 1 As shown, the top of the two extension arms 4 is provided with an abutment plate 401.

[0031] The detailed working process of this embodiment is as follows: the abutment plate 401 can increase the contact surface with the top of the floor, thereby improving stability.

[0032] like Figure 1 As shown, a rubber pad 402 is provided on the abutment plate 401.

[0033] The detailed working process of this embodiment is as follows: the rubber pad 402 can prevent the abutment plate 401 from directly and rigidly contacting the top of the floor, thus avoiding wear and tear on the top of the floor.

[0034] like Figure 1 As shown, the construction platform 2 is equipped with an extendable extension platform 201.

[0035] The detailed working process of this embodiment is as follows: With the extension platform 201 set up, the area required for construction can be appropriately extended, thereby improving work efficiency.

[0036] The implementation principle of this application embodiment is as follows: First, the lifting vehicle is driven to the required position, and then the operating shaft 304 is rotated to drive the two studs 302 to rotate, thereby driving the extension arm 4 to extend upward to abut against the top of the floor to form a stable support. Then, the construction platform 2 is driven to rise to the required height to carry out high-altitude construction.

[0037] 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 this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
