Description

Technical Field

[0002] Building materials are various materials used in construction projects. There are many types of building materials, which can be roughly divided into inorganic materials, organic materials and composite materials. Most of the current building materials are generally composed of inorganic non-metallic materials and organic materials. In the process of construction at a construction site, it is often necessary to cut building materials on-site according to the size of use. However, when performing circular cutting on cylindrical building materials, traditional cutting devices cannot achieve an ideal cutting method, which will result in the cut end and the cut tail end not being able to overlap in a circle on the cylindrical material when cutting the cylindrical material, or causing the cut end face to tilt, which cannot meet the use requirements. After the cutting is completed, the cut portion needs to be burred. In this way, the construction efficiency is relatively low. Therefore, a new type of cutting device is needed that can quickly cut a flush port and remove the port burrs at the same time. Summary of the invention

[0044] When the device is running, the servo motor 33 drives the second worm 31 to rotate, the rotation of the second worm 31 drives the second worm wheel 26 to rotate, the rotation of the second worm wheel 26 drives the transmission sleeve 25 to rotate, the rotation of the transmission sleeve 25 causes the threaded rod 27 to extend from the transmission sleeve 25 and drives the receiving frame 28 to move, the movement of the receiving frame 28 drives the cutting machine 29 to approach the steel pipe until the cutting machine 29 reaches a suitable cutting distance, during which the telescopic guide rod 32 adaptively extends with the movement of the receiving frame 28.

[0045] In order to show the detailed structure of the rotating mechanism, the following features are also set:

[0046] The rotating mechanism also includes a receiving ring frame 34 rotatably arranged on the limiting ring plate 5, a transfer ring gear 35 coaxially fixedly arranged on the receiving ring frame 34, a connecting transverse plate 37 fixedly arranged between the two support frames 21, a receiving seat 41 fixedly arranged on the limiting ring plate 5, a driven wheel 42 rotatably arranged on the receiving seat 41, a receiving gear 43 coaxially fixedly arranged on the driven wheel 42, a power motor 38 fixedly arranged on the connecting transverse plate 37, a driving wheel 39 coaxially fixedly arranged on the output shaft of the power motor 38 and a transmission belt 40 arranged between the driving wheel 39 and the driven wheel 42, the receiving gear 43 is meshed with the transfer ring gear 35, and the support ring 36 is coaxially fixedly connected to the receiving ring frame 34.

[0048] In order to show the detailed structure of the vibration mechanism, the following features are also set:

[0049] The vibration mechanism includes an adapter bracket 45 and a bearing bracket 53 fixedly arranged on the cutting machine 29, a rotating shaft 46 rotatably arranged on the adapter bracket 45, a rotating disk 47 and an adapter wheel 49 coaxially fixedly arranged on the rotating shaft 46, a connecting plate 50 fixedly arranged on the adapter bracket 45, a resistance roller 51 rotatably arranged on the connecting plate 50, a connecting wheel 52 coaxially fixedly arranged on the resistance roller 51, a guide box 54 fixedly arranged on the bearing bracket 53, a sliding block 56 slidably arranged in the guide box 54, a sliding groove 55 opened on the side wall of the guide box 54 and a swing rod 48 one end of which is rotatably connected to the rotating disk 47, the other end of the swing rod 48 is rotatably connected to the sliding block 56, the adapter wheel 49 and the connecting wheel 52 are connected by a belt, one end of the file 44 is rotatably connected to the sliding block 56 by a torsion spring, and the sliding block 56 is the vibration output end of the vibration mechanism.

[0050] When the cutting machine 29 is driven by the lifting mechanism to move to a suitable cutting position, the resistance roller 51 also contacts the outer wall of the steel pipe. When the cutting machine 29 is driven by the supporting ring 36 to make a circular motion, the transfer bracket 45 and the bearing bracket 53 also move with the cutting machine 29. The resistance roller 51 contacts the outer wall of the steel pipe and rotates. The rotation of the resistance roller 51 drives the connecting wheel 52 to rotate. The rotation of the connecting wheel 52 drives the transfer wheel 49 to rotate. The rotation of the transfer wheel 49 drives the rotating disk 47 to rotate. The rotation of the rotating disk 47 drives the swing rod 48 to rotate. The rotation of the swing rod 48 drives the sliding block 56 to reciprocate in the guide box 54. The reciprocating motion of the sliding block 56 drives the file 44 to grind the cutting seam. It should be noted that since the file 44 and the sliding block 56 are connected by a torsion spring (under normal conditions, the file 44 is parallel to the straight line in the length direction of the guide box 54 under the action of the torsion spring), when the cutting machine 29 has not yet started cutting, the file 44 resists the outer wall of the steel pipe and undergoes adaptive twisting. After the cutting machine 29 cuts a gap, as the cutting machine 29 gradually moves, the file 44 will penetrate into the cutting seam, and then the file 44 will straighten again under the action of the torsion spring, and then the cutting seam will be grinded under the drive of the sliding block 56.

[0051] In order to enable the device to move flexibly and improve work efficiency, the following features are also set:

[0052] A slide rail 22 is provided at the bottom of each support frame 21 , a slide member 23 is slidably provided on the slide rail 22 , the slide member 23 is fixedly connected to the bottom of the support frame 21 , and two abutting screws 24 are threadedly provided on each support frame 21 , and the abutting screws 24 pass through the slide member 23 and abut against the slide rail 22 .

After adjusting to the appropriate position, the support frame 21 is fixed by the tightening screw 24, thereby increasing the use range of the device and improving production efficiency.

[0054] The method for cutting building materials for construction sites comprises the following steps:

[0055] S1: Fix the large diameter steel pipe through the clamping mechanism;

[0056] S2: The lifting mechanism is started, driving the cutting machine 29 to move to a suitable cutting position and start cutting the steel pipe;

[0057] S3: Start the rotating mechanism, which drives the support ring 36 to rotate, so that the cutter 29 starts to rotate around the steel pipe to cut, and at the same time, the vibration mechanism drives the file 44 to vibrate to grind the gap cut by the cutter 29;

[0058] S4: The steel pipe cutting is completed and the relevant staff removes the steel pipe.

[0059] The working principle of this device is as follows: the relevant staff uses the lifting equipment to lift the steel pipe to be cut to the inner pipe 3, and then adjusts the position of the support frame 21 on the slide rail 22, and fixes the support frame 21 by the tightening screw 24, and then starts the driving motor 20 to drive the first worm 19 to rotate, and the rotation of the first worm 19 drives the first worm wheel 13 to rotate, and the rotation of the first worm wheel 13 drives the transfer gear 11 to rotate through the connecting circular frame 12, and the rotation of the transfer gear 11 drives the transmission ring gear 17 to rotate, and the transmission ring gear 17 drives the rotating ring plate 14 to rotate through the connecting frame 16, and the rotating ring plate 14 rotates to make the limiting arc groove 15 resist the sliding column 8, and the sliding column 8 causes the tightening plate 7 to move along the limiting groove 6, so that the tightening plate 7 drives the arc clamping plate 9 to approach the steel pipe until the steel pipe is clamped. Subsequently, the servo motor 33 drives the second worm 31 to rotate, and the rotation of the second worm 31 drives the second worm wheel 26 to rotate, and the rotation of the second worm wheel 26 drives the transmission sleeve 25 to rotate. The rotation of the transmission sleeve 25 causes the threaded rod 27 to extend from the transmission sleeve 25 and drives the receiving frame 28 to move. The movement of the receiving frame 28 drives the cutting machine 29 to approach the steel pipe until the cutting machine 29 reaches a suitable cutting distance. At the same time, the resistance roller 51 also contacts the outer wall of the steel pipe. Then, the cutting machine 29 starts to cut the steel pipe, and the power motor 38 drives the driving wheel 39 to rotate. The rotation of the driving wheel 39 drives the driven wheel 42 to rotate through the transmission belt 40. The rotation of the driven wheel 42 drives the receiving gear 43 to rotate. The rotation of the receiving gear 43 drives the transfer ring gear 35 to rotate. The rotation of the transfer ring gear 35 drives the receiving ring frame 34 to rotate. The rotation of the receiving ring frame 34 drives the support ring 36 to rotate, so that the cutting machine 29 cuts around the steel pipe, and the resistance roller 51 contacts the outer wall of the steel pipe and rotates. The rotation of the resistance roller 51 drives the connecting wheel 52 to rotate. The rotation of the connecting wheel 52 drives the transfer wheel 49 to rotate. The rotation of the transfer wheel 49 drives the rotating disk 47 to rotate. The rotation of the rotating disk 47 drives the swing rod 48 to rotate. The rotation of the swing rod 48 drives the sliding block 56 to reciprocate in the guide box 54. The reciprocating motion of the sliding block 56 drives the file 44 to grind the cutting seam.
