It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0021] Please refer to Figures 1 to 5The embodiment of the present invention provides a detachable vacuum adsorption ladder protection pad 100, comprising a hollow cylinder 101, a bottom plate 102 is sealed at the lower end of the cylinder 101, a pressure plate 103 located above the bottom plate 102 is sealed in the cylinder 101, the bottom plate 102, the pressure plate 103 and the cylinder 101 enclose an installation chamber 105, a vacuum pump 108 and a controller 109 are installed in the installation chamber 105, the controller 109 is connected to an exhaust trigger button 110, the exhaust trigger button 110 is installed at the exhaust end of the vacuum pump 108, and the exhaust trigger button 110 extends out through the exhaust hole 106 on the bottom plate 102 The bottom plate 102 is provided with an air inlet 107, and the pressure plate 103 is provided with pressure sensors 104 connected to the controller 109 at the four corners and / or four sides. The controller 109 is also connected with an anti-overturning alarm 111 and a reset button 112. The anti-overturning alarm 111 can be arranged in the installation chamber 105, and the reset button 112 is arranged on the side wall of the cylinder 101. A flexible pad 116 is installed on the lower end surface of the cylinder 101, and the flexible pad 116 is lower than the bottom plate 102. At least two cross-distributed top rods 117 are threadedly connected on the side wall of the cylinder 101 above the pressure plate 103. The pressure sensors 104 are at least 4 arranged in the four directions of east, south, west and north, and can also be 4 arranged in the four corners of southeast, northeast, west and northwest, or a combination of the two. The anti-overturning alarm 111 can be installed at any position of the installation chamber 105 without affecting other components. Figures 1 to 4 The specific installation position of the anti-overturning alarm 111 is not shown in the figure. The controller 109 may be a microprocessor such as a single chip microcomputer, and the anti-overturning alarm may be an audible and visual alarm.

[0022] The detachable vacuum adsorption ladder protection pad 100 provided in the embodiment of the present invention is installed on each leg of the ladder through the cylinder 101 when in use, so that the leg of the ladder is against the pressure plate 103, and the detachable vacuum adsorption ladder protection pad 100 is fixedly installed on each leg of the ladder by rotating the top rod 117. Each detachable vacuum adsorption ladder protection pad 100 contacts the ground through the flexible pad 116 thereon, and the exhaust trigger button 110 opens the exhaust hole 106 after contacting the ground. After the vacuum pump 108 is started by the controller 109, the vacuum pump 108 vacuumizes the closed space between the area enclosed by the flexible pad 116 and the ground through the exhaust hole 106, so that the detachable vacuum adsorption ladder protection pad 100 is adsorbed on the ground through the closed space in the vacuum state of the enclosed area between the flexible pad 116 and the ground, thereby improving the stability of the ladder support on the ground and avoiding the risk of the ladder overturning. Compared with the conventional anti-slip pad, it has the advantage of keeping the ladder stable and reliable when in use. The gravity of the ladder and the construction workers climbing on it is applied to the pressure plate 103. The pressure sensors 104 in various directions on the pressure plate 103 detect the pressure value of the ladder on the detachable vacuum adsorption ladder protection pad 100 and transmit it to the controller 109. The controller 109 compares the pressure values ​​detected by the four pressure sensors 104. When one of the pressure values ​​exceeds the predetermined value range, or the difference between one of the pressure values ​​and the other pressure values ​​exceeds the range, the controller 109 triggers the anti-overturning alarm 111 to send an alarm signal to remind the construction workers that there is a risk of overturning, so as to 111 reminds construction workers not to walk on the ladder, so as to avoid scratches and other damages caused by walking on the ladder, especially to avoid damage to smooth floors such as wooden floors, tiles, and marble. When the ladder is used, the vacuum pump 108 is turned off by the reset button 112, and the air entering the enclosed space of the enclosed area between the flexible pad 116 and the ground through the air inlet 107 releases the vacuum state, so that the detachable vacuum adsorption ladder protection pad 100 is de-adsorbed from the ground, and the ladder equipped with the detachable vacuum adsorption ladder protection pad 100 can be moved to the next construction location for use. When the pressure value of any one of the pressure sensors 104 exceeds the range, the force on each detachable vacuum adsorption ladder protection pad 100 is uneven, indicating that the ladder is tilted, and there is a safety risk of walking on the ladder or construction workers climbing the ladder eccentrically. That is, when the ladder is tilted, the pressure sensor 104 at the corresponding position can trigger the anti-overturning alarm to send an alarm signal for safety reminder, thereby ensuring the safety of construction workers using the ladder and avoiding damage to the ground caused by walking on the ladder.

[0023] Please refer to Figure 5In order to facilitate the construction workers on the ladder to clearly hear the alarm reminder, the detachable vacuum adsorption ladder protection pad 100 provided in the embodiment of the present invention also includes a Bluetooth module 113 connected to the controller 109, and the Bluetooth module 113 is connected to a mobile terminal 119 such as a smart phone and a tablet computer. Then the controller 109 can transmit the alarm signal of the anti-overturning alarm 111 to the mobile terminal 119 through the Bluetooth module 113. After receiving the alarm signal, the mobile terminal 119 can send a vibration or sound signal, and then the construction workers on the ladder wearing the smart terminal 120 are reminded at close range. The Bluetooth module 113 can be set in the installation chamber 105.

[0024] In order to prevent slipping, in the detachable vacuum adsorption ladder protection pad 100 provided in the embodiment of the present invention, the flexible pad 116 can be a rubber pad.

[0025] In order to power the controller 109, the detachable vacuum adsorption ladder protection pad 100 provided by the embodiment of the present invention has the controller 109 connected to a power supply 114. In order to avoid the influence of the line on the movement of the ladder and reduce the construction obstacles of the ground line, the power supply 114 can be a mobile power supply.

The rotation of the top rod 117 by the handle 118 facilitates the disassembly and assembly of the detachable vacuum adsorption ladder protection pad 100 on the supporting foot of a metal ladder such as an aluminum alloy. The cross-distributed top rods 117 can tighten the top rod 117 to the supporting foot in different directions. The top rod 117 can be adapted to different sizes of the supporting foot of the ladder, and has good versatility. In order to provide a tightening effect, each of the top rods 117 is vertically cross-distributed.
