[0037] Compared with the prior art, the advantages of the present invention are as follows: 1. A positioning mechanism is symmetrically arranged at one end of the bracket. On the one hand, the positioning mechanism is used to limit the equipment so that it is stabilized at the set position, which is convenient for cutting and cutting accuracy. On the other hand, the height of one end of the bracket can be adjusted by a screw rod so that the heights of the two ends of the bracket are consistent and reach a horizontal state, which is convenient for the diamond wire saw machine to move without affecting the cutting accuracy. In this way, leveling is more convenient, and leveling can be easily performed in different occasions, which is more convenient to use;

[0038] 2. The limiting mechanism includes a tile vacuum suction cup, a counterweight plate, and a steel chisel, which correspond to indoor tile floors, hard floors such as cement, and mud floors. In this way, the equipment can be stably fixed no matter where it is used, and it is more convenient to use;

[0039] 3. A rotatable bracket is provided, and a servo motor is provided, and the gear and rack are meshed, so that the servo motor can be used to drive the diamond wire saw machine to move slowly along the first track, realizing remote control, which is more convenient. In addition, the handle can be turned to rotate the bracket to separate the gear and rack, so that the diamond wire saw machine can be pushed by manpower to move quickly along the first track, realizing rapid adjustment of the position of the diamond wire saw machine, saving more time;

[0040] 4. The guide wheel mechanism includes a U-shaped frame, a wheel frame and a guide wheel. A second slide rail is provided in the U-shaped frame. The wheel frame and the guide wheel can move along the second slide rail. In this way, when cutting, there is no need to move the guide wheel mechanism from time to time. It is only necessary to slide and adjust the guide wheel to the position of the second slide rail according to the cutting progress. When the guide wheel reaches the end of the second slide rail, the guide wheel mechanism is moved again and fixed. This saves time and avoids the trouble of moving the guide wheel mechanism all the time and fixing it, which is more labor-saving.

[0078] ① Preparation: According to the horizontal cutting or vertical cutting method, determine the hole location, clean up the debris around the hole, ensure the safety of the construction area, determine the model and specifications of the water drill, and prepare the supporting equipment and tools. Figure 13-15 As shown;

[0079] ② Mark the hole position: Use measuring tools to mark the position of the hole to be opened and the size of the hole;

[0080] ③ Drilling equipment layout: Place the water drill and related equipment in a suitable position to ensure the stability of the water drill so that it does not shake during use and the safety of the working platform, and ensure that the working platform is firmly fixed;

[0081] ④ Drilling operation: fix the water drill at the hole position and adjust the water drill to align with the hole position, start the water drill equipment to perform the hole drilling operation;

[0082] ⑤ Clean the hole: After opening the hole, clean out the dirt and gravel at the hole in time to keep the hole clean;

[0083] ⑥ Check the quality of the hole: use a stainless steel ruler or other suitable tools such as a level to measure the size and flatness of the hole to ensure that the quality of the hole meets the requirements;

[0084] ⑦Handle the hole: according to the specific requirements, fill, fix or polish the hole to make it smooth and beautiful;

[0085] ⑧ Closing work: clean up the construction site, count the tools and equipment, and complete the construction after taking safety precautions;

[0086] Construction precautions

[0087] ① The water drill should be operated and kept by a dedicated person. The operator must not allow water to enter the motor during operation or storage. When not in use, the drill should be wiped clean in time and placed in a dry room. When not in use for a long time, the drill bit should be removed and a layer of grease should be applied to the guide rail;

[0088] ③During operation, the water drill must be fixed reliably to prevent accidents. When working at height, certain safety measures must be taken; before operation, check whether the frame is fixed firmly and the drill bit is installed properly;

[0089] ④ During drilling operations, there must be sufficient water to prevent waterless operations;

[0090] ⑤ The drilling rig must not be started with load to avoid damage to the drilling rig and injury to personnel;

[0091] ⑥During operation, the vents of the drilling rig must not be blocked to prevent the motor from overheating and burning out;

[0092] ⑦ When drilling holes in the wall with a water drill, it is easy to injure the user's arm if you are not concentrating. Therefore, during the drilling process, the construction workers must concentrate and firmly grasp the handle of the water drill. If they encounter steel bars, they must stop drilling and quickly turn off the water drill switch; when the concrete quality is not high, sand is falling or the drill is stuck, the drill must be stopped immediately and the drill must not be forced down;

[0093] ⑧ After the drilling rig has been used for a period of time, the gap between the slider and the column will increase, and the gap adjustment screw should be tightened appropriately;

[0094] ⑨In order to facilitate the removal of the drill bit, apply lubricating oil to the threaded part before installing the drill bit. Other threaded parts of the drill should also be frequently lubricated with grease to prevent rust;

[0095] ⑩When drilling holes, pay attention to the intersection of the horizontal and vertical directions. First, drill the vertical hole, then erect a straight pole, use a pull rope to pull down and erect another straight pole. Use the vertical line of the hanging wire in the middle as the coordinate of the horizontal hole, and drill the hole straightly. At the same time, you can also drill the horizontal hole first, and then drill the vertical hole. This should be freely arranged according to the site conditions;

[0096] S3, rope saw construction,

[0097] S3-1. Installation of wire saw: ① Before installing the diamond wire saw 200, confirm the direction of the diamond wire saw 200. Make sure that the direction of the arrow on the diamond wire saw 200 is consistent with the sawing direction. For some used diamond wire saws 200, the direction of the arrow on the rubber cannot be clearly seen. The direction of the diamond wire saw 200 can be identified according to the direction of the diamond particles on the beads. Insert the diamond wire saw 200 through the holes drilled on the surface to be cut. For objects that do not require drilling, just put the diamond wire saw 200 on the surface to be cut.

[0098] ② Connect the diamond wire saw 200 through the diamond wire saw 200 joint; before connecting, the diamond wire saw 200 should be rotated a certain number of times in advance, the rotation direction is counterclockwise, the number of rotations is 1 to 3 (turns / m). According to the use degree of the diamond wire saw 200, the new rope can be 1 turn / m, and the used diamond wire saw 200 should be gradually increased according to the use degree, and the maximum number of twisting turns should not exceed 3 turns / m. Too much will cause wire rope fatigue and cause beads to string, and the diamond wire saw 200 will be charged;

[0099] S3-2. Installation of guide wheel mechanism

[0100] ① When cutting a larger cutting surface with a thickness greater than half a meter, it is necessary to install a guide wheel mechanism on the track passed by the diamond wire saw 200 and fix it; all guide wheel mechanisms, the driving flywheel of the diamond wire saw machine 100, the diamond wire saw 200 and the surface to be cut are in the same plane, and the number of guide wheel mechanisms used can be adjusted according to actual needs, and there is no special restriction;

[0101] The specific installation method is as follows:

[0102] Insert the fixing sheet 609 with nails, steel chisels, etc. to fix the guide wheel mechanism to the cutting route of the diamond wire saw 200, and make the guide wheel 603 located at the center of the cutting route. At the same time, point the end of the U-shaped frame 601 with the cross bar toward the diamond wire saw machine 100 to prevent the diamond wire saw 200 from cutting the U-shaped frame 601. Then move the wheel frame 602 to the end of the U-shaped frame 601 away from the diamond wire saw machine 100, and then tighten the bolt 608 to position and fix the wheel frame 602. In this way, the guide wheel 603 is fixed, and then the diamond wire saw 200 is placed on the guide wheel 603.

[0103] For relatively small cutting surfaces with a thickness of less than half a meter, the guide wheel mechanism may not be used;

[0104] ② When cutting the vertical cutting surface or the horizontal cutting surface, after the guide wheel has been cutting at the initial position for a period of time, the guide wheel should be moved and re-fixed in time according to the actual situation to avoid the beaded rope cutting the guide wheel bracket;

[0105] Specifically, during the cutting process, as the cutting is carried out, the bolt 608 can be loosened, and then the wheel frame 602 and the guide wheel 603 are moved toward the diamond wire saw machine 100 to tighten the diamond wire saw 200, and then the bolt 608 is tightened to fix the wheel frame 602. When the wheel frame 602 moves to the other end of the U-shaped frame 601, the U-shaped frame 601 can be disassembled and then repositioned and fixed, and the cycle is repeated until the cutting is completed;

[0106] S3-3. Installation and cutting of rope saw machine

[0107] ① Installation of the track: Pull the bracket 300, move the cutting device to a position 1-3m away from the front end of the surface to be cut, and then lay the bracket 300 flat on the ground. Then, install the corresponding limit mechanism on the screw 402 according to the site conditions, and use the limit mechanism to limit the device. At the same time, the height of one end of the bracket 300 can be adjusted by twisting the screw 402 to ensure that there is no obvious horizontal error between the bracket 300 and the working surface of the first track 502 thereon, that is, the horizontal error is within 1cm;

[0108] The details are as follows: the screw rod 402 can be driven up and down by rotating the rotating handle 403, thereby adjusting the height of one end of the bracket 300, ensuring the overall horizontal arrangement of the bracket 300. When the device is used indoors with a tile floor, the limit mechanism uses a tile vacuum suction cup 404, and the tile floor can be sucked by the tile vacuum suction cup 404, so that the device can be fixed; for some hardened and rough places such as cement floors or asphalt floors, the limit mechanism uses a counterweight plate 405, which is inserted into the gap in the ground through a cone 406, thereby fixing the device. For muddy ground, or ground that can be inserted with steel drill 407, the limit mechanism uses steel drill 407, so that the steel drill 407 can be inserted into the ground to fix the equipment. When the steel drill 407 is inserted into the ground, the upper end of the steel drill 407 is directly hit, which will cause the upper end to deform. Therefore, in order to prevent the upper end of the steel drill 407 from deforming, a hole can be made by a steel drill thinner than the steel drill 407, and then the steel drill 407 is inserted into the hole. In this way, the steel drill 407 can be inserted into the hole without applying too much force to the steel drill 407, and because the diameter of the steel drill 407 is larger than the hole diameter, it can also fix the equipment;

[0109] When installing the limiting mechanism, for the tile vacuum suction cup 404 and the counterweight plate 405, the connecting column 409 is inserted into the insertion hole 408 to achieve connection, and the pin is inserted into the pin hole to fix it;

[0110] As for the steel drill 407, directly insert the steel drill 407 into the socket 408 to achieve connection, and fix it by inserting the pin into the pin hole;

[0111] The handle 510 is pulled to drive the bracket 507 to rotate upward, so that the gear 508 and the rack 505 are separated, and then the latch 513 is pushed to limit the handle 510. Then, the diamond wire saw machine 100 can be pushed along the first track 502 by manpower to achieve the rapid movement of the position of the diamond wire saw machine 100, and the diamond wire saw machine 100 is moved to the side close to the object to be cut. Then, the latch 513 is pulled back to release the restriction on the handle 510, and under the action of the tension spring 509, the gear 508 will mesh with the rack 505 again;

[0112] ② Adjust the guide wheel of the diamond wire saw machine 100 to the appropriate position, put the diamond wire saw 200 on the driving flywheel and guide wheel of the diamond wire saw machine 100, adjust the guide wheel to the appropriate position, so that the diamond wire saw 200 has a sufficiently large wrap angle on the driving flywheel, the wrap angle is more than 10 degrees, and there is a cutting angle of about 15 degrees on the cutting surface, then lock the guide wheel connecting rod on the diamond wire saw machine 100, and prepare to start cutting;

[0113] ③ Review the water, electricity, safety, anti-pollution protection measures and supporting facilities. After the review is qualified, start the cutting equipment button, start the servo motor 506 to drive the gear 508 to rotate, and the gear 508 drives the chassis 501 and the diamond wire saw machine 100 on it to move along the first track 502, adjust the tension of the diamond wire saw 200 to make the diamond wire saw 200 chain always in a cutting stress state. During the cutting process, the servo motor 506 is remotely controlled to rotate slowly through the control system of the diamond wire saw machine 100, and the position of the diamond wire saw machine 100 is slowly adjusted to make the diamond wire saw 200 chain always in a cutting stress state; supply cooling water throughout the cutting process to do a good job of cooling until the cutting is completed.

[0114] Precautions in rope saw cutting construction

[0115] ① The guide wheel mechanism is installed firmly and accurately, and the rim of the guide wheel 603 is aligned with the center line of the rope threading hole, ensuring the effective cutting speed of the cutting surface and improving work efficiency;

[0116] ② According to the arrow direction of the diamond wire saw 200 chain (beads), ensure that the diamond wire saw 200 chain is installed correctly, and ensure that there is no gap at the connection of the diamond wire saw 200 chain;

[0117] ③Do a good job in the on-site placement of facilities and personnel safety management, set up construction and safety areas, and prevent the diamond wire saw 200 from suddenly disconnecting and causing safety accidents;

[0118] ④ During the cutting process, the speed of the diamond wire saw 200 should be ensured, sufficient cooling should be ensured to cool the chain and take away the powder, and at the same time ensure the cutting stability and sustainability.
