Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a climbing ladder device for safe support of pipe piles. Background Technology

[0002] In recent years, with the rapid development of my country's new energy industry, photovoltaic power generation, as a renewable and clean energy source, has become an important part of the national energy development strategy, and mountain photovoltaic power generation has become a major development direction.

[0003] Consequently, PHC pipe piles have been widely used in mountainous areas. After the PHC pipe pile construction is completed and passes inspection, rust removal and painting of the pile head plate are required to prevent rusting. After the PHC pipe piles are installed, their height above the ground is generally between 2.5m and 3.5m. This considerable height necessitates the use of ladders for work, and workers must wear safety harnesses at this height. However, photovoltaic construction often lacks nearby high points for securing safety harnesses, and the cylindrical shape of PHC pipe piles, coupled with the often sloping and uneven terrain of mountainous areas unsuitable for erecting ordinary ladders, often results in ladders being unable to be safely placed against the ground, posing a safety hazard. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a climbing ladder device for safe support of pipe piles, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model discloses a climbing ladder device for safe support of pipe piles. The technical solution adopted includes a clamping mechanism. The clamping mechanism includes claws and a main body. The claws are rotatably connected to both sides of the main body and have locking bolts. A storage groove is opened on the other side of the main body. Lifting arms are rotatably connected to both sides of the storage groove. The other end of the lifting arms is rotatably connected to both sides of the climbing ladder. A positioning block is located below the lifting arm and is detachably connected to the main body. An anti-deviation mechanism is detachably connected to the top of the climbing ladder. A binding rail is placed on the main body. There are binding straps of a binding tightening device on the steps at the top of the climbing ladder. The binding tightening device binds the binding rail and the steps at the top of the climbing ladder together. The binding tightening device is existing technology and can conveniently control the tightening and loosening of the binding straps.

[0006] As a preferred technical solution of this utility model, a rotating shaft is provided on one side of the gripper, and a rotating hole is opened at the position opposite to the rotating shaft of the main body. The gripper is rotatably connected to the main body through the rotating shaft and the rotating hole. A through hole is opened at the other end of the gripper, and the gripper is locked by the locking bolt to realize the clamping of the PHC pipe pile.

[0007] As a preferred technical solution of this utility model, the gripper has anti-slip rubber inside, which increases the friction between the gripping mechanism and the PHC pipe pile, so that it will not slip.

[0008] As a preferred technical solution of this utility model, positioning screw holes are provided on the main body on both sides of the storage groove. There are multiple positioning screw holes arranged linearly on the main body. The positioning block is detachably connected to the positioning screw hole by positioning bolt. The ladder can be fixed in a fixed state at different angles by installing the positioning block on the positioning screw hole at different positions.

[0009] As a preferred technical solution of this utility model, the anti-deviation mechanism includes an anti-deviation ring, a fixed seat is mirror-mounted at the rear end of the anti-deviation ring, a through hole is opened in the middle of the fixed seat, and a plug groove is opened at the bottom of the fixed seat. The plug groove cooperates with the ladder column and is fastened together with bolts. By disassembling and replacing the anti-deviation mechanism with different diameters, it can be used to fix larger diameter PHC pipe columns.

[0010] Compared with the prior art, the beneficial effects of this utility model are: this utility model clamps the ladder to the PHC pipe pile through the clamping mechanism, and uses the lifting arm to lift the ladder off the ground and fix it, so that the ladder can ignore the ground environment of the PHC pipe pile. By raising or lowering the height of the positioning block, the ladder can change different angles and thus reach different positions of the PHC pipe pile. Attached Figure Description

Example 1

[0020] like Figures 1 to 7 As shown, this utility model discloses a climbing ladder device for safe support of pipe piles. The technical solution adopted includes a clamping mechanism 2, which includes a main body 3 and a gripper 4. The main body 3 is rectangular. Rotation holes 301 are opened on both sides of one side of the main body 3, and a storage groove 302 is opened on the other side of the main body 3. Positioning screw holes 304 are opened on both sides of the storage groove 302 on the main body 3. There are multiple positioning screw holes 304 arranged linearly on both sides of the main body 3. A binding rail 303 is provided on the top of the main body 3. The gripper 4 is semi-circular on the first surface of the main body 3. A rotating shaft 401 is provided at one end of the gripper 4. The gripper 4 is rotatably connected to the main body 3 through the cooperation of the rotating shaft 401 and the rotation hole 301. The gripper 4 has anti-slip rubber inside. A through hole is provided at the other end of the gripper 4. A locking bolt 402 is provided in the through hole. The storage groove 302 contains... The two sides of the main body are rotatably connected to the lifting arms 6. The lifting arms 6 are connected to the side wall of the storage groove 302 through damping bearings. There is a positioning block 5 below the lifting arm 6. The positioning block 5 is fixed to the main body 3 through positioning bolts 501 and positioning screw holes 304. The top of the positioning block 5 abuts against the bottom of the lifting arm 6. The other end of the lifting arm 6 is rotatably connected to the ladder 7 through the damping bearing. The top of the ladder 7 is detachably connected to the anti-deviation mechanism 8. The anti-deviation mechanism 8 includes an anti-deviation ring 801. There is a fixed seat 802 behind the anti-deviation ring 801. There are two fixed seats 802, which are mirror images of each other. A through hole is opened in the middle of the fixed seat 802. An insertion groove 803 is opened at the bottom of the fixed seat 802. The insertion groove 803 is inserted into the top of the column of the ladder 7 and fixed by bolts. The highest step of the ladder 7 is connected to the binding rails 303 through a binding tightening device 9.

[0021] The working principle of this utility model is as follows: When working on the top of the PHC tubing 1, first clamp the jaws 4 at the lower end of the PHC tubing 1 and tighten them with locking bolts 402 to prevent the jaws 4 from sliding up and down. At this point, the state is... Figure 6 As shown, pull the ladder 7 out to the desired angle, and install the positioning block 5 into the positioning screw hole 304 at a suitable position below the lifting arm 6 using the positioning bolt 501, thereby preventing the lifting arm 6 from continuing to move downwards. Figure 7 As shown, by tightening the binding tensioner 9, the straps of the binding tensioner 9 will directly tighten the highest step of the ladder 7 and the railing 303, so that the ladder 7 is completely fixed. At this time, the bottom of the ladder 7 is suspended in the air, and the environment of the ground that is not conducive to supporting the ladder 7 can be ignored. Workers can climb the ladder 7 directly and hang the safety belt on the foot pedal to work safely and stably.
