Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but the present invention is not limited thereto.
Fig. 1 and 2 show the preferred scheme of the utility model, which comprises a ladder stand body 1, a speed reducing motor 2, a transmission gear 3, a fixed seat 4 and a connecting rod 5.
The cat ladder body 1 is the aluminum alloy material, divide into cat ladder 11 and dull and stereotyped 12, and when putting down the state, 11 slopes of cat ladder set up, and the middle part is equipped with multistage footboard, and dull and stereotyped 12 is the top layer footboard, and the level sets up, 11 fixed mounting in dull and stereotyped 12 one end of cat ladder.
The other end of the flat plate 12 is hinged and mounted on a fixed seat 4 through a connecting rod 5, the fixed seat 4 is arranged on an inner bottom plate of an external carriage 6, a ladder door 7 is arranged on a carriage body of the carriage 6 (when the ladder door 7 is not used, the ladder body 1 is hidden inside), and the fixed seat 4 is arranged on a bottom plate close to the door edge; the connecting rod 5 is connected with the reducing motor 2 through the transmission gear 3 and is driven to rotate by the reducing motor 2; the speed reducing motor 2 is a positive and negative rotation motor and is fixed on the bottom plate of the carriage 6, and a gear box is arranged outside the transmission gear 3.
The crawling ladder body 1 is fixedly connected with the connecting rod 5 in a welding mode, so that the crawling ladder body 1 is stable and firm in the overturning process; connecting rod 5 rotates to be installed in fixing base 4, inlays the snap ring through the bearing spacing, and fixing base 4 is fixed in on the bottom plate of carriage 6 through the bolt.
The transmission gear 3 is fixedly installed on the connecting rod 5 in a limiting mode through a key groove and a clamping ring and is in tooth joint with an output gear of the speed reducing motor 2 to achieve transmission.
The controller 8 is arranged beside the ladder door 7 and is connected with the speed reducing motor 2 through a circuit to control the ladder body 1 to be put down and put up. A protective switch 71 is arranged above the climbing door 7; the top end of the ladder stand body 1 in a folding state is provided with a limit switch 13, and the upper end of the gear box of the transmission gear 3 and the bottom end of the side surface close to the vehicle door are both provided with proximity switches (namely an upper limit proximity switch 31 and a lower limit proximity switch 32).
