Description

A steel cage hoisting device for pipe pile industry

technical field

The utility model relates to a construction method in the construction industry, in particular to a steel cage hoisting device in the pipe pile industry.

Background technique

Pipe piles are widely used in China, covering the entire construction field based on the information currently available. For example, in civil buildings (the pipe piles used in this field are the most), buildings with more than 5 floors in areas with poor foundations will use pipe piles to reinforce the foundation. In addition, large industrial construction projects such as steel plants, power plants, chemical industry, paper mills, etc., all use a large number of pipe piles as foundation piles. In recent years, with the rapid development of port projects, the throughput of my country's ports this year will reach the world's largest port and the construction of large docks. The number of large-scale pipe piles used is increasing, and the length of a single section of pipe piles is also getting longer. .

After the steel cage is manufactured, the two ends of the steel cage are often hooked manually during transportation, and then the steel cage is lifted to the predetermined location by a bridge crane. However, with the increase of building construction requirements, the length of pipe piles used in viaducts and water engineering is getting longer and longer, and the length of steel cages required is also correspondingly increased. Therefore, in the traditional hoisting and transportation method, by manually hooking the two ends of the steel cage to lift, since the force point is mainly borne by the two ends, it is easy to cause the force point of the steel cage and the bending deformation of the middle part of the steel cage, and in serious cases, the Affecting the detachment of solder joints will cause the steel cage to deform and fall apart, causing unnecessary losses, and the falling of the steel cage will also pose a serious threat to the personal safety of construction personnel.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a steel cage hoisting method that is quick, convenient, and safe to use

The technical scheme that the utility model solves its technical problem adopts is:

A steel cage hoisting device for the pipe pile industry, comprising a steel wire rope connected to a crane, a bracket is hoisted under the steel wire rope, two or more steel wire ropes are fixed, and a clamping mechanism is fixedly installed on the bracket, the clamp The two ends of the tightening mechanism are telescopic rods, and the ends of the telescopic rods are connected with manipulators.

The transmission mode of the clamping mechanism is a transmission shaft.

A curved plate is fixedly installed at the front end of the manipulator.

The beneficial effect of the utility model is: use the wire rope to hoist the bracket, fix the clamping mechanism on the bracket, control the manipulator to clamp the lower half of the steel cage through the clamping mechanism, and then lift the steel cage. The whole process does not require manual removal of the hook cage, and is clamped by a manipulator, so that the force on each point of the steel cage is uniform, and the steel cage will not be deformed, or desoldering and fracture will not occur, and the working process is safer and more efficient.

The transmission mode of the clamping mechanism is the transmission shaft, and the control of the manipulator action is realized through the transmission shaft, because the transmission of the transmission shaft is more accurate, the energy loss is less, and there is no transmission delay. The steel cage is deformed after excessive clamping; and the arc-shaped plate is used as the extension of the manipulator, which increases the contact area with the steel cage, reduces the local force, and protects the steel cage.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 1 is the three-dimensional structure schematic diagram of the present utility model;

Fig. 2 is a side view of the utility model.

Detailed ways

With reference to Fig. 1, Fig. 2, a kind of pipe pile industry steel cage hoisting device, comprises the steel wire rope 1 that is connected on the crane, and steel wire rope 1 is hoisted with bracket 2, and steel wire rope is two or more than two, and the fixed installation on the bracket 2 has Clamping mechanism 3, the two ends of the clamping mechanism 3 are telescopic rods 31, and the ends of the telescopic rods 31 are connected with manipulators 4.

The hoisting steps are as follows:

a. Hoist the bracket 2 on the wire rope 1;

b. By lowering the steel wire rope 1 to lower the bracket 2, the telescopic rod 31 of the clamping mechanism 3 is extended to control the manipulator 4 to open, so that the manipulator 4 can accommodate the steel cage 5 to enter;

c. Lowering the bracket 2 makes the lowermost end of the manipulator 4 lower than the upper part of the steel cage 5; so that when the manipulator is folded, most of the steel cage will be wrapped in the manipulator.

d. Control the clamping mechanism 3 to clamp, and the telescopic rod 31 shrinks, thereby driving the manipulator 4 to retract, so that the distance between the manipulator 4 is smaller than the diameter of the steel cage 5;

e. Lift the wire rope 1 to drive the bracket 2 to lift the steel cage 5 .

As a preferred mode of the present utility model: the preferred transmission mode of the clamping mechanism 3 is the transmission shaft, and the control of the manipulator action is realized through the transmission shaft, because the transmission of the transmission shaft is more accurate and the energy loss is less, which can realize point-to-point stop And other characteristics, to prevent the deformation of the steel cage after excessive clamping.

As other embodiments of the present utility model: the clamping mechanism 3 may also adopt chain transmission, friction wheel transmission, screw transmission, pneumatic transmission, belt pulley transmission and the like to realize the control of the manipulator.

As a preferred mode of the present utility model: there are two steel wire ropes 1, which are respectively symmetrically fixed at both ends of the support 2, so as to maintain the balance of the support 2. When hoisting, the two lifting points are stressed at the same time, and rise and fall slowly, avoiding vibration and preventing the steel cage 5 from being damaged. The manipulator 4 adopts two arc-shaped plates 41, which increases the contact area between the manipulator 4 and the steel cage 5, thereby reducing the local stress on the steel cage 5. The entire hoisting process does not require manual removal of the hook cage, and the manipulator 4 is used to clamp, so that the force on each point of the steel cage is uniform, and the steel cage will not be deformed, desoldered and broken, and the working process is safer and more efficient.

Using this method to hoist steel cages in the pipe pile industry can meet the requirements that the length of pipe piles used in viaducts and water projects is getting longer and longer, and the length of steel cages required is correspondingly increased, and can be replaced by machinery It eliminates manual labor and realizes the transformation process from labor-intensive to intensive economy.
