When the rack 111 falls, the rack 111 and the connecting column 114 can move downward relative to the brake wheel 122, so that the rack 126 can drive the brake wheel 122 to rotate, and the pressing touch parts 124 of the two brake wheels 122 can rotate with the brake wheel 122 and press the two sides of the guide plate 103, that is, the brake is realized by clamping the guide plate 103 through the pressing touch parts 124 of the two brake wheels 122, preventing the elevator 110 from further falling and improving safety.

[0041] Specifically, referring to Figure 2 , the rack 111 is provided with a walking mechanism 115, the walking mechanism 115 has a plurality of pulleys 116, which press the two side walls of the stand column 102 along the front-rear direction shown in the figure, realizing the sliding connection of the rack 111 on the rack 101. It can be understood that the rack 111 is provided with a walking mechanism 115 at both ends in the width direction, realizing the stable lifting movement of the rack 111. Moreover, the rack 111 is provided with an anti-falling mechanism 120 at both ends in the width direction, which can improve the anti-falling effect.

[0042] Referring to Figure 3 , Figure 4 and Figure 5 , the mounting bracket 121 is provided with a pin shaft 127 and a spring 128, the spring 128 can elastically press the pin shaft 127 to the connecting column 114, and the pin shaft 127 can make the connecting column 114 have a downward movement trend, so that the pressing touch part 124 presses the guide plate 103 to generate a braking trend, which can improve the response speed of the anti-falling mechanism 120 when the rack 111 falls, and further improve the safety.

[0043] It can be understood that the rack 111 is provided with a mounting seat 112 extending in the width direction of the rack 111, the mounting seat 112 is provided with a floating bracket 113, the anti-falling mechanism 120 is provided with a mounting bracket 121, both ends of the floating bracket 113 are respectively pivotally connected to the mounting seat 112 and the floating bracket 113, realizing the floating installation of the anti-falling mechanism 120 on the rack 111, compared with rigid connection, the position of the anti-falling mechanism 120 and the rack 111 does not need to be adjusted during installation, which is beneficial to simplify the installation steps, and can avoid the collision between the anti-falling mechanism 120 and the rack 101 during the lifting of the rack 111, improving the smoothness of operation.

[0044] It can be understood that the anti-falling mechanism 120 further comprises a pressure contact wheel 123, the pressure contact part 124 is located on the pressure contact wheel 123, the pressure contact wheel 123 is installed on the brake wheel 122, and the pressure contact wheel 123 is eccentrically arranged with the brake wheel 122, the pressure contact wheel 123 can rotate around the axis of the brake wheel 122, so that the pressure contact part 124 extends radially outward of the brake wheel 122, and the brake effect is realized.

[0045] With reference to Figure 6 It can be understood that when the rack 111 falls, the rack 111, the connecting column 114 and the rack gear 126 simultaneously move downward relative to the mounting frame 121; since the mounting frame 121 is installed on the mounting seat 112, at this time the mounting frame 121 also has a falling trend, but the rack 111 falls earlier than the mounting frame 121, so the rack 111 can move downward relative to the mounting frame 121. Therefore, in order to enable the mounting frame 121 to clamp the guide plate 103 through the pressure contact part 124 when moving downward relative to the column 102, the brake wheel 122 needs to drive the pressure contact part 124 to rotate towards the guide plate 103, so as to realize self-locking when falling, thereby stabilizing the brake. Therefore, the transmission wheel 131 is arranged between the rack gear 126 and the brake wheel 122, the transmission wheel 131 is engaged with the rack gear 126 and the brake wheel 122 at the same time, so as to enable the brake wheel 122 to drive the pressure contact part 124 to rotate towards the guide plate 103 when the rack gear 126 moves downward relative to the mounting frame 121, thereby realizing the brake effect. Further, the maximum outer diameter of the transmission wheel 131 is smaller than the maximum outer diameter of the brake wheel 122, which can improve the driving torque of the rack gear 126 on the brake wheel 122, thereby improving the response speed of the brake.
