Due to the complex operation of the existing wire saw machine, the structural design defects, the difficulty in maintenance and replacement, time-consuming and labor-intensive, and low cutting efficiency, although a cutting transposition device for directional cutting of structures has been designed on the market, the device can be used for cutting, but due to the technical defects in the design of the steering device, on the one hand, there is no corresponding rope designed to fix the wire saw, which makes the wire saw easy to fall off during use; on the other hand, since the various components are designed to be fixedly connected, when one of the components is damaged, it is not possible to simply replace one of the components, but it will affect the entire construction and require the equipment to be shut down for maintenance, which is time-consuming and labor-intensive. In short, it is often inconvenient.

[0040] The working principle is: before using the diamond wire saw cut object and the wire saw machine direction pulley steering device of the above-mentioned design structure, it is necessary to manufacture and install it as a spare.

[0041] First, the operator marks the positioning line to be cut on the target cutting object (8), and uses a drilling machine to drill four lifting holes with a hole diameter of 40 cm on the bridge wing plate. The truck crane is in place, and the lifting rope is installed to ensure that the lifting wire rope is straight;

[0042] Then, the operator moves the wire saw and wire cutting machine (5) to the position, places the wire cutting machine (5) behind the block to be cut on the bridge deck, and first manufactures and assembles the pulley device as a backup;

[0043] During assembly, the operator first installs the first pulley block (2), the second pulley block (3) and the position limiting and anti-slipping member (7) on the fixed bracket (1);

[0046] When in use, the operator first fixes the fixed bracket (1) on the bridge deck by means of several bolts and several steel plate pads, and places the fixed bracket (1) at the rear edge of the positioning line to be cut. When installing, it is noted that the upper crossbeam (14) of the fixed bracket (1) is parallel to the positioning line to be cut of the target cutting object (8); then one end of the diamond wire saw (6) is sequentially passed through the driving wheel (51) on the wire cutting machine (5), the first upper pulley (213), the mounting sleeve (11) at the lower end of the first upper pulley, the first lower pulley (223), the target cutting object (8), the second lower pulley (323), the mounting sleeve (11) at the lower end of the second lower pulley, the second upper pulley (313), and then connected to the other end of the diamond wire saw (6) to form a closed loop;

[0110] Example 1

[0111] Before using the diamond wire saw cut object and the wire saw machine direction pulley steering device of the above-mentioned design structure, it is necessary to manufacture and install it as a spare.

[0112] First, the operator marks the positioning line to be cut on the target cutting object 8, and uses a drilling machine to drill four lifting holes with a hole diameter of 40 cm on the bridge wing plate. The truck crane is in place, and the lifting rope is installed to ensure that the lifting wire rope is straight;

[0113] Then, the operator moves the wire saw wire cutting machine 5 to the position, places the wire cutting machine 5 behind the block to be cut on the bridge deck, and first manufactures and assembles the pulley device as a backup;

[0114] During assembly, the operator first installs the first pulley block 2, the second pulley block 3 and the limit anti-dropping member 7 on the fixed bracket 1;

[0115] During installation, the operator first installs the first upper pulley member 21 on the upper part of the corresponding installation sleeve 11 through the locking member; then installs the first lower pulley member 22 on the lower part of the corresponding installation sleeve 11 through the locking member, and the first pulley block 2 is assembled. Then, the operator installs the limit anti-slipping member 7 on the first upper pulley connecting rod 212 through the connecting plate, and the limit anti-slipping member 7 is located above the first upper pulley 213, and the lower end of the limit anti-slipping member 7 is not in contact with the first upper pulley 213, and the installation of the limit anti-slipping member 7 is completed;

[0116] Finally, the operator fastens the second upper pulley member 31 to the upper part of the corresponding mounting sleeve 11 through the locking member, and then, the operator fastens the second lower pulley member 32 to the lower part of the corresponding mounting sleeve 11 through the locking member, thus completing the installation of the second pulley group 3 and finally completing the assembly process of the pulley device.

[0117] When in use, the operator first fixes the fixed bracket 1 on the bridge deck through several bolts and several steel plate pads, and places the fixed bracket 1 at the rear edge of the positioning line to be cut. When installing, pay attention to the crossbeam 14 on the fixed bracket 1 being parallel to the positioning line to be cut of the target cutting object 8; then, one end of the diamond wire saw 6 is passed through the driving wheel 51 on the wire cutting machine 5, the first upper pulley 213, the installation sleeve 11 at the lower end of the first upper pulley, the first lower pulley 223, the target cutting object 8, the second lower pulley 323, the installation sleeve 11 at the lower end of the second lower pulley, the second upper pulley 313, and then connected to the other end of the diamond wire saw 6 to form a closed loop;

[0118] Next, the operator adjusts the directions of the first upper pulley 213 and the second upper pulley 313 to ensure that the diamond wire saw 6 is in the outer grooves of each pulley. After the directions are adjusted, the bolts on the upper and left sides of the mounting sleeve 11 are tightened to ensure that the pulley block does not shift during operation.
