Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): referring to fig. 1, an anti-skid power construction hanging ladder comprises two parallel upright posts 1, a plurality of cross bars 11 uniformly distributed on the upright posts 1, and a hook 2 fixed at one end of the upright posts 1, wherein the hook 2 is made of insulating plastics.

Referring to fig. 2 and 3, two fixing sleeves 3 are provided on the side of the upright 1, and the fixing sleeves 3 are fixed on the two uprights 1 respectively. All wear to be equipped with slide bar 31 in fixed cover 3, the one end that is close to couple 2 on slide bar 31 all rotates and is connected with two jack catchs 4, has stopper 35 at the other end threaded connection of slide bar 31, and stopper 35 contradicts in the side of fixed cover 3. Rotate stopper 35 for stopper 35 conflicts in the side of fixed cover 3, and slide bar 31 slides in fixed cover 3, further makes fixed cover 3 conflict in the lateral surface of jack catch 4, thereby makes two jack catches 4 draw close each other, until tightly cliing with cable 7, thereby makes the clamp force between cable 7 and the jack catch 4 strengthen, improves the frictional force between jack catch 4 and the cable 7 through increasing the clamp force, thereby prevents that couple 2 from sliding on cable 7.

Referring to fig. 3 and 4, a U-shaped frame 32 is fixedly arranged at one end of the sliding rod 31, a rotating shaft 33 is inserted into the U-shaped frame 32 in an interference manner, and the two claws 4 are rotatably connected to the rotating shaft 33. One end threaded connection who is close to jack catch 4 on fixed cover 3 has adjusting collar 34, and adjusting collar 34 makes jack catch 4's height and couple 2 with the height, further makes jack catch 4 only play the effect of centre gripping to cable 7 to make staff and the gravity of hanging the ladder fall on couple 2, and not on jack catch 4, prevent that cable 7 from breaking away from jack catch 4. The U-shaped frame 32 can rotate inside the adjusting sleeve 34, and when the two jaws 4 are closed, the maximum distance between the two jaws 4 is larger than the inner diameter of the adjusting sleeve 34, so that when the sliding rod 31 slides in the adjusting sleeve 34, the side surfaces of the adjusting sleeve 34 abut against the two jaws 4 and approach each other.

Referring to fig. 3 and 4, a dovetail groove 42 is formed on the inner side of the claw 4, a rubber pad 41 is arranged in the dovetail groove 42, the rubber pad 41 is matched in the dovetail groove 42 through a dovetail block, a glue layer is further arranged on the surface where the rubber pad 41 is attached to the claw 4, and the connection strength between the rubber pad 41 and the claw 4 is further improved through glue and the like. A stopper plate 43 is provided on the claw 4 at an end away from the U-shaped bracket 32, and the stopper plate 43 again restricts the rubber pad 41 from being separated from the claw 4 in the sliding direction of the rubber pad 41. The rubber pad 41 serves to increase the coefficient of friction between the pawl 4 and the cable 7 while preventing the pawl 4 from scratching the cable 7. Springs 44 are arranged on the inner sides of the two claws 4, and two ends of each spring 44 are fixed on the claws 4, so that when the claws 4 are separated from the adjusting sleeve 34, the claws 4 are in an open state, and the cables 7 can conveniently enter the middle position of the two claws 4.

Referring to fig. 3, an annular groove 36 is provided on the outer wall of the fixing sleeve 3, a clamp 37 is provided in the annular groove 36, the clamp 37 is in an arc-shaped opening shape, the clamp 37 is fixed on the column 1 by a bolt, and the annular groove 36 and the clamp 37 are matched, so that the fixing sleeve 3 can be detachably connected on the column 1, and the axial displacement of the fixing sleeve 3 is limited.

Referring to fig. 5, a first connecting shaft 5 is disposed on the upright 1 along a direction perpendicular to the upright 1, and two first connecting shafts 5 are disposed opposite to each other and parallel to the cross bar 11. The first connecting shaft 5 comprises a spline shaft 51 fixed on the upright post 1 and a stud 52 coaxial with the spline shaft 51, the maximum diameter of the stud 52 is smaller than the minimum diameter of the spline shaft 51, and a spline hole 22 is formed in the hook 2. When the hook 2 is fitted on the spline shaft 51, at which time the hook 2 will not be able to rotate, a lock nut 53 is screwed onto the stud 52, the nut 53 having a diameter greater than the maximum diameter of the spline shaft 51, so that the nut 53 can restrain the hook 2 on the spline shaft 51. When the angle between the hook 2 and the upright post 1 needs to be adjusted, the nut 53 is detached from the stud 52 at the moment, the hook 2 is detached from the spline shaft 51, and the hook 2 is matched with the piece changing shaft after an angle is adjusted, so that the angle of the hook 2 can be adjusted according to actual requirements.

Referring to fig. 5 and 6, a second connecting shaft 6 is fixed on the upright post 1 in a direction perpendicular to the length direction of the upright post 1 and also perpendicular to the cross bar 11, and the structure of the second connecting shaft 6 is the same as that of the first connecting shaft 5. When the hooks 2 are simultaneously assembled on the first connecting shaft 5, the hooks 2 are hung on the same cable 7; when the hook 2 is simultaneously assembled on the second connecting shaft 6, the hook 2 will be hung on the two cables 7 at this time, which makes it possible to adjust the position of the hook 2 more practically. The cover is equipped with rubber sleeve 21 on couple 2, and rubber sleeve 21 is fixed on couple 2, and rubber sleeve 21 has the rubber material to make, and rubber sleeve 21 is used for increasing the coefficient of friction between couple 2 and the cable 7, further prevents to hang the ladder and skids.

Referring to fig. 2, an anti-slip sleeve 12 is sleeved on one end of the upright post 1 far away from the hook 2, when the hanging ladder is used as a common ladder, the lower end of the upright post 1 is in contact with the ground, and the anti-slip sleeve 12 effectively prevents the end of the upright post 1 in contact with the ground from sliding downwards.

The action process is as follows: firstly hang couple 2 on cable 7, then rotate stopper 35 for slide bar 31 slides in fixed cover 3, and then makes adjusting sleeve 34 contradict at the back of jack catch 4, makes jack catch 4 can be lived cable 7 centre gripping, thereby prevents that couple 2 from sliding on cable 7.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications to the present embodiment without inventive contribution as required after reading the present specification, but all of them are protected by patent laws within the scope of the claims of the present invention.
