Detailed Description
The technical scheme of the utility model is further described below with reference to the accompanying drawings and the specific embodiments.
The novel pulling plate dismounting structure comprises a pulling plate 1 and a special lifting appliance 2, wherein the special lifting appliance 2 is of a structure with a narrow upper part and a wide lower part, the top of the special lifting appliance 2 is connected with a lifting hook 4 through a rope penetrating through a hanging point 3, the bottom of the special lifting appliance 2 is connected with the pulling plate 1 through a pin shaft penetrating through the hanging point 3 and a clip 8, and stop blocks 9 are arranged at two sides of the hanging point 3 at the bottom of the special lifting appliance 2; the pulling plates 1 are connected through a first pin shaft 5 and a second pin shaft 6 which penetrate through corresponding connecting holes, and spring rings 7 are arranged at the end parts of the pin shafts. Wherein, special lifting appliance 2 top is equipped with 2 hanging points 3, and 2 hanging points 3 are connected with lifting hook 4 through the rope respectively. The bottom of the special lifting appliance 2 is provided with 3 hanging points 3, and both sides of the 3 hanging points 3 are provided with stop blocks 9. The stop block 9 is connected with the special lifting tool 2 through a plurality of bolts 10 and a plurality of nuts 11. The hanging point 3 is positioned at the gravity center position of the single pulling plate 1. The pulling plate 1 is arranged outside the arm section of the crawler crane. The distance between the pulling plate 1 and the arm joint is 0-1.5m.
As shown in fig. 2 and 3, the special lifting tool 2 is connected with the stop block 9 through a plurality of bolts 10 and a plurality of nuts 11, and the distance between the special lifting tool 2 and the stop block 9 can be finely adjusted through the bolts 10 and the nuts 11. The main body structure of the special lifting appliance 2 is formed by splicing and welding a long plate or a seamless pipe and the like, 2 hanging points 3 are reserved above the plate and are connected with a lifting hook 4 through ropes; a plurality of hanging points 3 are reserved below the plate, and each hanging point 3 side is provided with 1 stop block 9. And a special hoisting hole is designed in the middle clamping plate of the pull plate 1.
