DETAILED DESCRIPTION

[0020] In order to make the technical personnel in the art better understand the technical scheme of the utility model, the utility model will be further described in detail below with reference to the drawings.

[0021] As Figures 1-2 shown, an emergency speed limiting protection mechanism and window cleaning machine, including the basket 100, the basket 100 includes bottom plate 1 and the guardrail 10 arranged on the three faces of bottom plate 1, bottom plate 1 is rotatably provided with door body 11, and a plurality of first sliding grooves 14 arranged in linear array are symmetrically formed on two guardrails 10, a first sliding rod 15 is slidably arranged on the first sliding groove 14, a plurality of connecting pipes 17 arranged in linear array and connected with the first sliding groove 14 are arranged on the two guardrails 10, and a suction accessory 18 is arranged on the connecting pipe 17.

[0022] Including window cleaning machine, the bottom of window cleaning machine is provided with a plurality of connecting pieces 13, and the basket 100 is connected with the window cleaning machine through the plurality of connecting pieces 13

[0023] Specifically, in use, the connecting piece 13 at the bottom of the window cleaning machine is connected with the basket 100, then the driving mechanism in the window cleaning machine is started, the basket 100 is moved upward, and the glass is cleaned, at the same time, after reaching the specified working position, the plurality of suction accessories 18 are attached to the glass, then the plurality of first sliding rods 15 are moved in the first sliding groove 14, and the gap between the suction accessory 18 and the glass forms negative pressure, so that the plurality of suction accessories 18 are fixed on the glass, and the basket 100 cannot shake.

[0024] In the above scheme, the bottom plate 1 and the three faces of the guardrail 10 realize the composition of the basket 100, the door body 11 realizes the workers to go up and down on the basket 100, the first sliding groove 14 symmetrically formed on the two side guardrails 10 realizes the sliding of the first sliding rod 15, and the first sliding rod 15 realizes the movement of the gas in the first sliding groove 14 to the connecting pipe 17, at the same time, the suction accessory 18 is attached to the glass, and the basket 100 is attached to the glass, which avoids the influence of strong wind on the basket 100, so that the basket 100 shakes in the air and affects the safety.

[0025] As a further embodiment of the utility model, according to Figure 1 and Figure 2 shown, the plurality of first sliding rods 15 are provided with first push plates 16.

[0026] Specific, pull the first push plate 16 can drive a plurality of first slide bar 15 in the first slide groove 14 sliding.

[0027] As a further provided embodiment of the utility model, according to Figure 2 As shown in the figure, two guardrails 10 are symmetrically provided with a plurality of second slide grooves 21 arranged in linear array, and second slide bars 22 are slidingly arranged in the second slide grooves 21, and abutting heads 23 are arranged on the second slide bars 22.

[0028] Further, the abutting heads 23 are provided with non-slip pads 24, and second push plates 25 are arranged on the plurality of second slide bars 22.

[0029] Specifically, when the basket 100 suddenly drops in danger, the second push plate 25 is pushed to drive the plurality of second slide bars 22 to slide in the second slide groove 21, so that the non-slip pad 24 on the abutting head 23 contacts the glass to reduce the speed of the basket 100 descending, and time is gained for ground personnel to take measures.

[0030] As a further provided embodiment of the utility model, according to Figure 2 As shown in the figure, a plurality of guardrails 10 are provided with speed reduction members 20, and air inlets 200 are arranged at the bottom of the speed reduction members 20.

[0031] Specifically, when the basket 100 suddenly drops, the air inlet 200 at the bottom of the speed reduction member 20 faces downward, which will pour the wind during the descending into the speed reduction member 20, so that the speed reduction member 20 expands to reduce the speed of the basket 100 descending. It should be noted that the default state of the speed reduction member 20 is drooping, and the accompanying Figure 1 is to better show the structure.

[0032] Working principle: when in use, the connecting member 13 at the bottom of the window cleaning machine is connected with the basket 100, and then the driving mechanism in the window cleaning machine is started to move the basket 100 upward and wipe the glass. At the same time, after reaching the specified working position, the plurality of suction accessories 18 are attached to the glass, then the plurality of first slide bars 15 are moved in the first slide groove 14, and the gap between the suction accessories 18 and the glass forms negative pressure to fix the plurality of suction accessories 18 on the glass, so that the basket 100 will not shake. At the same time, when the basket 100 suddenly drops in danger, the second push plate 25 is pushed to drive the plurality of second slide bars 22 to slide in the second slide groove 21, so that the non-slip pad 24 on the abutting head 23 contacts the glass to reduce the speed of the basket 100 descending, and time is gained for ground personnel to take measures. The plurality of suction accessories 18 also increase the friction force to realize the reduction of the descending speed of the basket 100. At the same time, the air inlet 200 at the bottom of the speed reduction member 20 faces downward, which will pour the wind during the descending into the speed reduction member 20, so that the speed reduction member 20 expands to reduce the speed of the basket 100 descending.

[0033] The above has only described certain exemplary embodiments of the present application by way of illustration, and it is needless to say that the described embodiments can be modified in various ways without departing from the spirit and scope of the present application for those skilled in the art. Therefore, the above drawings and descriptions are illustrative in nature, and should not be understood as limiting the scope of protection of the claims of the present application.
