Description

Technical Field

[0001] The utility model relates to the technical field of lifting hanging baskets, in particular to an indoor aerial work platform. Background Art

[0002] The workshop of the Yangtze River Fish Detection Station is usually located on the upper side of the dam, with a floor height of about 6m. Electric hoists are arranged parallel to the top to transfer fish between the room and the fish collection well area.

[0003] Since the driving track of the electric hoist is located above the fish collecting well area, the high-rise maintenance platform vehicle and lifting equipment cannot support maintenance personnel to perform maintenance on the driving track. In addition, due to the location of the inspection station workshop, the high-rise maintenance platform vehicle is difficult to enter the workshop. The conventional maintenance method is to build a movable scaffolding. The maintenance personnel climb to the top of the scaffolding to clean the electric hoist and the track. This operation method has great safety hazards and low operation efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is that the maintenance of aerial crane tracks and electric hoists has great potential safety hazards and low operating efficiency.

[0006] Preferably, the two guide rods are arranged to be inclined relative to each other, and the top ends of the two guide rods are arranged relative to each other, and the distance between the movable ends of the two guide rods is smaller than the distance between the two traveling vehicles connected by the cable.

[0007] Preferably, an oblique support rod is fixedly provided at an angle on the top of the hanging basket, and the top end of the oblique support rod is fixedly connected to the guide rod.

[0008] Preferably, a fixed wheel is rotatably provided at the bottom of the locker, and a movable wheel is also slidably provided inside the locker. The movable wheel and the fixed wheel are distributed on the inner and outer sides of the hook. The movable end of the locker is threadedly connected to a locking bolt whose screw end abuts against the movable wheel.

[0009] Preferably, a pair of fixed wheels are arranged on the outside of the hook, the fixed wheels and the movable wheels are distributed in a triangle, and arc grooves are provided in the middle of the fixed wheels and the movable wheels.

[0010] Preferably, a sliding groove is provided at the movable end of the locker along the length direction, a moving block is provided in the sliding groove, the moving wheel is connected to the moving block, and the screw end of the locking bolt abuts against the moving block.

[0011] Preferably, the thickness of the movable end of the hook is greater than the thickness of the hook body.

[0012] 1. This utility model provides an indoor aerial work platform. The platform is equipped with a hanging basket. A winch inside the basket is connected to the hook of an electric hoist via a cable and a lock. The winch is controlled to retract and unreel, allowing the basket to be raised and lowered vertically. The raised and lowered basket can accommodate multiple workers, and the stable basket provides a safe working platform for workers, improving their safety and efficiency.

[0013] 2. The two hanging baskets are distributed between the two cranes. The cables are guided by the fixed pulley at the top of the guide rod so that the cables are in a tensioned state.

[0018] like Figure 1 and Figure 2 The utility model provides an indoor aerial work platform, comprising a hanging basket 4, winches 5 provided at both ends of the hanging basket 4, guide rods 6 arranged at both ends of the top of the hanging basket 4, and lockers 9 fixed to the movable ends of cables 8. The lockers 9 are connected to the hook 3 of the electric hoist 2 at the bottom of the crane 1. A fixed pulley is provided at the top of the guide rod 6, and the cable 8 is wound around the fixed pulley.

[0019] Utilizing a crane 1 in a workshop and an electric hoist 2 mounted at the bottom of the crane 1, the electric hoist 2 is controlled to lower the hook 3, which is then connected to the hook 3 via a lock 9, thereby connecting the hanging basket 4 to the hook 3. The electric hoist 2 is then controlled to raise the hook 3. During the ascent of the hook 3, the winch 5 is controlled to unwind synchronously to prevent the hanging basket 4 from being lifted. After the hook 3 reaches its upper limit, the worker places maintenance tools in the hanging basket 4 and synchronously controls the two winches 5 within the hanging basket 4 to rewind. The cables 8 within the winches 5 raise the hanging basket 4 as they are reeled in, allowing the worker to perform maintenance on the crane 1 and the electric hoist 2. During maintenance, the crane 1 can also be controlled to move axially, driving the hanging basket 4 to move synchronously, allowing the worker to perform maintenance on the entire crane 1 and its track. Furthermore, the crane 1 can also drive the hanging basket 4 to the top of the workshop's fish collection well, where the worker controls the winch 5 to unwind and clean the well interior.

[0020] like Figure 1 The two guide rods 6 are arranged to be tilted relative to each other, and the top ends of the two guide rods 6 are arranged relative to each other, and the distance between the movable ends of the two guide rods 6 is smaller than the distance between the two traveling vehicles 1 connected by the cable 8.

[0021] By arranging the guide rod 6 at an angle, the cable 8 is in a tightened state. The cable 8 is located on the inner ring of the fixed pulley. The two cables 8 and the hanging basket 4 are at an acute angle, which can prevent the hanging basket 4 from shaking after the hanging basket 4 is lifted into the air.

[0022] like Figure 1 As shown, in order to improve the stability of the guide rod 6, a diagonal brace 7 is fixedly arranged on the top of the hanging basket 4, and the top end of the diagonal brace 7 is fixedly connected to the guide rod 6. The diagonal brace 7 strengthens the support of the guide rod 6 to prevent the guide rod 6 from bending.

[0023] like Figure 1 and Figure 2 The bottom of the locker 9 is provided with a fixed wheel 11 for rotation, and a movable wheel 12 is also provided in the locker 9 for sliding. The movable wheel 12 and the fixed wheel 11 are distributed on the inner and outer sides of the hook 3. The movable end of the locker 9 is threadedly connected to a locking bolt 13 whose screw end abuts against the movable wheel 12.

[0024] There are two fixed wheels 11 and one moving wheel 12. When installing the locker 9, by loosening the locking bolt 13, the gap between the moving wheel 12 and the fixed wheel 11 is increased, and the hook 3 can be inserted between the moving wheel 12 and the fixed wheel 11. Then, by tightening the locking bolt 13, the moving wheel 12 is pushed downward by the locking bolt 13, so that the moving wheel 12 cooperates with the fixed wheel 11 to clamp the hook 3. Figure 1As can be seen in the figure, the opening directions of the two hooks 3 on both sides are opposite. Since the cable 8 is always on the inner side of the two hooks 3, the locking device 9 can be prevented from moving out of the opening of the hook 3 during the lifting and lowering of the hanging basket 4.

[0025] like Figure 2 As shown. A pair of fixed wheels 11 are arranged on the outside of the hook 3. The fixed wheels 11 and the movable wheels 12 are arranged in a triangular pattern, and both are provided with arcuate grooves in the middle. As the hanging basket 4 ascends or descends, the angle of the cable 8 changes. Therefore, the fixed wheels 11 and the movable wheels 12 are configured to rotate. This not only allows them to effectively contact the surface of the hook 3, but also allows them to roll along the hook 3 after the angle of the cable 8 changes, thereby maintaining a stable connection point between the locker 9 and the cable 8.

[0026] like Figure 2 The movable end of the locker 9 is provided with a slide groove along the longitudinal direction, within which a movable block 10 is disposed. The movable wheel 12 is connected to the movable block 10, and the screw end of the locking bolt 13 abuts against the movable block 10. The locking bolt 13 pushes the movable block 10, and after the movable block 10 is tightly abutted, the position of the movable wheel 12 is defined.

[0027] like Figure 1 As shown, the thickness of the movable end of the hook 3 is greater than the thickness of the main body of the hook 3. When the locker 9 slides along the hook 3, the thickened movable end of the hook 3 makes it difficult for the locker 9 to move to the movable end of the hook 3, thereby ensuring the safety of the hanging basket 4.
