Detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
nullAs shown in Figures 1 to 5，A kind of sectionally smooth join formula elevator pit cat ladder，By being placed in the column 1 of both sides and being arranged between two root posts 1 and form with the fixing treadle 3 being connected of column 1，As shown in Figure 4，For making column 1 be connected with pedal-rod 3 more closely with firm，Here connected mode is that rivet is fixing to be connected，Additionally described sectionally smooth join formula elevator pit cat ladder includes cat ladder segmented body a and lower cat ladder segmented body b，And clamp device 9，Between described upper cat ladder segmented body a and lower cat ladder segmented body b, end connects by clamp device 9 is fixing，Described upper cat ladder segmented body a and junction, lower cat ladder segmented body b end are provided with at least one can coordinate fixing column fixing hole 11 with clamp device 9，Described clamp device 9 is by U-shaped outside link plate 13、U-shaped interior connecting plate 14 and bolt 6 and packing ring 7、Nut 8 forms，Connecting plate 14 is designed with in U-shaped outside link plate 13 and U-shaped at least one connecting plate fixing hole 15 for bolt 6 traverse，Described U-shaped outside link plate 13 overcoat is fastened on cat ladder segmented body a and junction, lower cat ladder segmented body b end，Described U-shaped interior connecting plate 14 is built-in is fastened on cat ladder segmented body a and junction, lower cat ladder segmented body b end，The bolt 6 connecting plate fixing hole 15 that to be then passed through in correspondence corresponding with the column fixing hole 11 of lower cat ladder segmented body b end and U-shaped interior connecting plate about 14 for cat ladder segmented body a after the connecting plate fixing hole 15 at U-shaped outside link plate 13 top，Eventually pass through the connecting plate fixing hole 15 of outside link plate 13 bottom and fasten with nut 8，For making fastening strength higher，One packing ring 7 can be set between nut 8 and outside link plate 13，For making cat ladder can carry out the fine setting of height when mounted according to hoistway actual grade，Shown column fixing hole 11 and connecting plate fixing hole 15 could be arranged to 5-10，When needs are finely tuned，The circular hole that can select diverse location is fixed thus adjusting cat ladder height，Adopt this segmentation mounting structure，Structure is relatively easy，The cat ladder adaptability to various dissimilar elevator pits can not only be kept，And owing to reducing volume and weight on the whole，Therefore packaging is saved、Freight and installation are artificial.
As improving embodiment, as shown in Figure 1, described sectionally smooth join formula elevator pit cat ladder tip position is provided with fixed support 2, fixed support 2 is fixed on well enclosure by steel expansion bolt 5, so described sectionally smooth join formula elevator pit cat ladder on elevator pit inwall, can add the safety of the upper and lower cat ladder of maintainer by safety and firmness more.
As further improving embodiment, as shown in Figure 3, non-slip feet set 4 is loaded onto and treadle 3 upper surface on described cat ladder arranges anti-slip tank 10 at described column 1 bottom set, it can in addition contain treadle 3 one side upward is set to the inclined plane horizontal by 20 °-30 °, so can effectively prevent cat ladder from sliding and preventing maintainer from falling down in trampling treadle 3 process, the upper and lower cat ladder of safety and stability more.
It is emphasized that: be only presently preferred embodiments of the present invention above, not the present invention is done any pro forma restriction, every any simple modification, equivalent variations and modification above example made according to the technical spirit of the present invention, all still falls within the scope of technical solution of the present invention.
