Crawling ladder special for cable well without well wall
A special ladder stand for a well-wall-free cable well relates to a ladder stand and is characterized in that two supporting rods (3) of a well mouth support are arranged at intervals, one end of each supporting rod is provided with an edge rod (11), an end rod (17) is arranged between the front ends of the two edge rods, an extending supporting rod (16) is arranged on the outer side of the end rod, and two ends of a rotating rod (5) are hinged to the two supporting rods; connecting plates (26) respectively arranged at the upper ends of two vertical plates (35) of a U-shaped rod (10) are fixed at the lower parts, close to the two ends, of the rotating rod; the upper ends of two vertical plates of a first U-shaped lifting rod (13) are respectively and movably connected with long circular grooves (36) of the two vertical plates of the U-shaped rod through shaft nails (14); the second, third, fourth or fifth U-shaped lifting rods are sequentially connected with the first, second, third and fourth U-shaped lifting rods to form a lifting ladder; the lifting crawling ladder is connected with the well mouth support through the rotating rod, and stability is facilitated when the lifting crawling ladder enters a cable well.
一种无井壁电缆井专用爬梯，涉及一种爬梯，井口支架的两支杆（3）间隔设置，两支杆的一端分别设有边部杆（11），两边部杆前端之间设有端部杆（17），端部杆的外侧设有延伸支杆（16），转杆（5）两端铰接连接两支杆；U形杆（10）两立板（35）上端分别设置的连接板（26）固定在转杆靠近两端下部，第一U形升降杆（13）的两立板上端分别通过轴钉（14）与U形杆两立板的长圆槽（36）活动连接；第二、第三、第四或第五U形升降杆按此方式与第一、第二、第三、第四U形升降杆依次连接形成升降爬梯；本发明升降爬梯通过转杆连接井口支架，方便了进入电缆井时的稳定。
