Detailed ways

The embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, but the utility model can be implemented in various ways defined and covered by the claims.

As the first aspect of the present invention, please refer to Fig. 2 to Fig. 4, a hoisting wire rope installation device is provided, especially, it can be applied to a trolley of a tower crane to fix the hoisting wire rope. The wire rope fixing seat 50 of the installation device for the hoisting wire rope includes a pressing plate 10 and a mounting plate 20, the pressing plate 10 and the mounting plate 20 are detachably connected, and a lifting wire rope clamping space is formed between the pressing plate 10 and the mounting plate 20; the vehicle frame 40 , The wire rope fixing seat 50 is installed on the vehicle frame 40 .

Please refer to FIG. 4 , when in use, the lifting wire rope 60 is sandwiched between the pressing plate 10 and the sticking plate 20 , and is located in the clamping space of the lifting wire rope 60 . Then the pressing plate 10 is fixed on the sticking plate 20, thereby clamping the hoisting wire rope 60, like this, just need not as in the prior art, the hoisting wire rope is bent and knotted, thus, can avoid lifting wire rope 60 At the same time, it is only necessary to fix the pressing plate 10 to the sticking plate 20. Therefore, the operation is very convenient, and the safety and efficiency of threading are improved.

Further, after being pressed by the pressing plate 10, the wedge joint 80 is pre-installed, and after the hoisting wire rope 60 is pulled to the position of the arm tip, only a pin shaft is needed to connect the hoisting wire rope to the arm tip , greatly reducing the operating time of the arm tip, thereby reducing the risk of operation.

Preferably, please refer to FIG. 4 , a first groove 11 is provided on the side of the pressing plate 10 facing the veneer 20 , a second groove 21 is provided on the side of the veneer 20 facing the pressing plate 10 , the first groove 11 and The second groove 21 is oppositely arranged, and a hoisting wire rope clamping space is formed between the first groove 11 and the second groove 21 . Preferably, the pressing plate 10 and the patching plate 20 are detachably connected by screws 30 . Preferably, one screw 30 is respectively provided on both sides of the first groove 11 . In particular, the bottoms of the first groove 11 and the second groove 21 are arc-shaped, so as to accommodate the hoisting wire rope 60 .

During use, the hoisting wire rope 60 is located in the hoisting wire rope clamping space formed by the first groove 11 and the second groove 21, thereby preventing the lifting wire rope 60 from moving during the movement, and effectively preventing the hoisting wire rope 60 from moving due to lifting. The movement of the lifting wire rope 60 causes the screw 30 to loosen, which improves the reliability of clamping. Preferably, please refer to FIG. 2 , a margin of a certain length L is reserved at one end of the hoisting wire rope 60 , especially, L is greater than or equal to 1.2 meters.

Preferably, the installation device for the hoisting wire rope further includes a screw 30 , and the pressing plate 10 and the sticking plate 20 are fixed on the vehicle frame 40 through the screw 30 .

Preferably, please refer to FIG. 2 , there are two wire rope fixing seats 50 , and the two wire rope fixing seats 50 are arranged sequentially along the moving direction of the installation device for lifting the wire rope. Preferably, the two wire rope fixing seats 50 are arranged obliquely to each other. Utilizing two inclined wire rope fixing seats 50 (for example, in a figure-eight shape), the part of the hoisting wire rope 60 between the two wire rope fixing seats 50 can form a certain arc, so as to achieve better fixing and clamping It also improves the stress of the hoisting wire rope and avoids space interference.

As a second aspect of the present invention, a tower crane is provided, including a hoisting wire rope 60 and an installation device for installing the hoisting wire rope, and the installation device is the above-mentioned installation device.

Preferably, the tower crane further includes a wedge joint 80 mounted on the free end of the hoisting wire rope 60 . Please refer to Fig. 5, the wedge joint 80 can be pre-installed at the end of the hoisting wire rope 60, after the hoisting wire rope 60 is pulled to the installation position 110 of the arm tip by the installation device of the hoisting wire rope, only a pin shaft 90 needs to be installed That is to say, the hoisting wire rope 60 can be connected with the tip of the arm. Further, a cotter pin 100 can be installed on the pin 90 to prevent the pin 90 from falling off. Therefore, the operating time at the tip of the arm is greatly reduced. Thereby reducing the risk of operation. When it is necessary to release the hoisting wire rope 60, unscrew the screw 30 to complete the threading of the hoisting wire rope.
