[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution for an aerial work lifting platform with a protection structure: an aerial work lifting platform with a protection structure, including a base 1, a lifting platform 3 is arranged at the upper end of the base 1, a scissor strut 4 and a driving cylinder 5 are arranged between the base 1 and the lifting platform 3, a protection structure 6 is arranged at the upper end of the lifting platform 3, and a control box is installed at the bottom of the lifting platform 3;

[0021] Among them, the protection structure 6 includes a protection frame 61, a limit switch 62 is arranged at the upper end of the protection frame 61, a slide groove 63 is opened inside the protection frame 61, a lifting frame 64 is arranged inside the protection frame 61, an extension bar 65 is arranged at the upper end of the lifting frame 64, a connecting block 66 is arranged inside the lifting frame 64, an electric push rod 67 is arranged at the bottom of the connecting block 66, a slide block 68 is arranged outside the lifting frame 64, and a connecting rod 69 is arranged on one side of the lifting frame 64.

[0022] As Figures 1-2 shown, universal wheels 2 are installed at the bottom of the base 1 through bolts. The number of the universal wheels 2 is four groups and they are arranged in an array. The base 1 and the lifting platform 3 are lifted through the scissor strut 4 and the driving cylinder 5. A control circuit board and a battery are arranged inside the control box. A remote control module and a communication module are arranged inside the control circuit board, which is beneficial to the lifting of the lifting platform 3. Its working principle is the prior art, so it will not be elaborated here.

[0023] As Figures 1-4As shown, the protective frame 61 is fixedly connected to the lifting platform 3. The number of limit switches 62 is two groups and they are symmetrically distributed. The limit switches 62 are electrically connected to the control circuit board. The number of sliding grooves 63 is four groups and they are distributed in an array. The inner ring area of the lifting frame 64 is smaller than the inner ring area of the protective frame 61. The extension strip 65 is fixedly connected to the lifting frame 64. The outer edge of the extension strip 65 is parallel to the outer edge of the protective frame 61, which is conducive to the contact between the extension strip 65 and the limit switch 62, playing a role in triggering the limit.

[0024] As Figures 1-4 shown, the connecting block 66 is fixedly connected to the lifting frame 64. The number of connecting blocks 66 is four groups and they are distributed in an array. The connecting block 66 is of a rectangular structure. The electric push rod 67 is fixedly connected to the lifting platform 3. A fixed connection is formed between the output end of the electric push rod 67 and the connecting block 66. The slider 68 is fixedly connected to the lifting frame 64.

[0025] The working principle of the present utility model is as follows: During the use of the platform, the user connects the mobile phone app to the control circuit board, and drives the scissor struts 4 to extend through remote control, thereby driving the lifting platform 3 to increase in height. Then, the protection structure 6 is started, and the height of the protection structure 6 is adjusted to the height suitable for the user's needs. The operation is convenient, without manual operation, and the height is adjustable.

[0026] It should be noted that through the upper end of the protection structure 6, when the height of the protection structure 6 is adjusted, under the support of the connecting block 66, the output end of the electric push rod 67 drives the connecting block 66 and the lifting frame 64 to rise, so that the lifting frame 64 drives the slider 68 to slide along the inside of the sliding groove 63 until the height of the lifting frame 64 rises to the set height, and then the operation of the electric push rod 67 is stopped, thereby positioning the lifting frame 64 to meet the use requirements. At the same time, when the lifting frame 64 descends, the extension strip 65 contacts the limit switch 62 and feeds back to the control circuit board, and the operation of the output end of the electric push rod 67 can be automatically stopped. The structure is simple, the operation is convenient, time-saving and labor-saving, and the safety of the lifting platform 3 is improved.

[0027] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
