Description of drawings

Fig. 1 is a schematic structural diagram of an embodiment of the utility model.

Detailed ways

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given together with the accompanying drawings and described in detail as follows.

Referring to Fig. 1, the utility model relates to a remote-controlled hydraulic double-rocker pole, which includes a pole main body composed of a standard section 1, a lifting frame 2 is provided at the bottom of the pole main body, and two A jacking cylinder 3 is provided on each side, an operating platform 4 is provided beside the movable end of the jacking cylinder, a pumping station 5 and a winch joint 6 are provided in the middle of the main body of the holding pole, and the upper end of the main body of the holding pole is provided with There is a base 7, the bearing is provided with a slewing support 8, the slewing support is provided with a rocker seat 9, the two sides of the rocker seat are provided with a rocker 10, and the middle part of the rocker seat is longitudinally A mast 11 is provided, and the top of the mast is provided with luffing wire ropes 12 respectively wound on the movable end of the rocker arm, and a lifting wire rope 13 is also wound around the movable end of the rocker arm.

Above-mentioned rocking arm comprises the rocking arm bottom section 14 that is hinged on rocking arm seat, is connected to the rocking arm standard section 15 on the rocking arm bottom section and is connected on the rocking arm standard section and the rocking arm cap 16 that is wound around hoisting wire rope.

Both sides of the above-mentioned mast middle part are respectively hinged with a rocker arm top frame 17 and a top support oil cylinder 18, and the movable end of the top support oil cylinder is hinged on the middle part of the corresponding side rocker arm top frame.

The top of the above-mentioned mast is provided with a mast cap 19 .

The movable end of the above-mentioned hoisting wire rope is provided with a suspension hook 20 .

During implementation:

The specific implementation process of the rocker arm is as follows:

When the pole-holding double rocker arm needs to be lowered, the control part is operated to make the luffing winch rotate, the luffing wire rope is sent out, the cylinder rod is automatically pushed out under the action of pressure oil, and the rocker arm top frame is driven to rotate, pushing the rocker arm to rotate, The rocker arm can only be lowered; when the rocker arm needs to be retracted, the luffing wire rope pulls the rocker arm to retract the arm, forcing the cylinder rod to retract. Because of the damping effect generated by the resistance of the oil cylinder, the rocker arm can only be retracted with the luffing rope. Slowly withdrawing, it will not hit the mast due to the rapid retraction of the rocker arm and cause the accumulation of the luffing wire rope, thus protecting the rocker arm and the mast and ensuring the smooth rope discharge of the luffing winch and ensuring the safety of the pole holding work.

The lifting operation process of the lifting frame and oil cylinder is as follows:

1) Each standard section is divided into 3 times to complete the jacking. When the oil cylinder is in place each time (the lower plane of the support iron is 20mm higher than the upper plane of the square pin), put the 4 square pins in place, and then slowly lower the oil cylinder. After the pin bears the load, the oil cylinder can return quickly;

2) Every time the jack is lifted, the jacking beam must be reliably supported in the supporting iron. When jacking up 50mm, stop and observe. After everything is normal, return the 4 square pins, continue to lift to the position, and the square pins are pinned;

3) In this way, lift 3 times in a cycle to complete the lifting process of a standard section;

4) Then use a crane to put another standard section on the trolley, adjust the position, slowly push it into the lifting frame, use the oil cylinder to lift it up slightly, and connect it with the upper standard section, the trolley withdraws, and the oil cylinder slowly puts down. Until the standard section is placed on the base plate support, if the jacking continues, the jacking can be carried out in the above sequence. If there is no more jacking, the standard section should be fixed on the base plate support.

5) The jacking process should be carefully observed and operated carefully. If abnormalities and alarms are found, stop immediately, and continue jacking after handling.

The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
