Description

Technical Field

[0001] This invention relates to the field of building material cutting technology, specifically to a fixed-distance circumferential cutting device for building construction materials. Background Technology

[0002] Circumferential cutting of construction materials is a pile head treatment process that uses specific cutting equipment to cut exposed pile heads on concrete at fixed intervals. By eliminating excessively long pile heads, construction quality and safety are improved, and the precise control and protection of reinforcing steel or timber during construction are further enhanced.

[0003] Currently, during construction, exposed steel bars or wood on concrete vary in length. Existing circumferential cutting equipment struggles to cut steel bars or wood of varying lengths appropriately. Furthermore, the cutting process generates a large amount of waste and polluting dust, posing significant safety hazards to users. Additionally, the smoothness of the cut surfaces of the steel bars or wood is difficult to guarantee.

[0004] In view of this, a fixed-distance circumferential cutting device for building construction materials was designed to solve the above problems. Summary of the Invention

The cutting distance control mechanism is used to adjust the opening and closing of the power supply mechanism to facilitate control of the cutting depth of reinforcing bars or wood. The power supply mechanism supplies power to the wire saw to facilitate cutting of reinforcing bars or wood, and the wire saw is located within the gap between the two ring pads.

[0009] In a preferred embodiment, the present invention may be further configured such that: the tangent adjustment mechanism includes a cylinder fixedly installed inside the protective cover, a movable frame is mounted on the cylinder, and the movable frame is movably mounted outside the pipe section at the top of the protective cover; two symmetrically distributed traction frames are movably mounted on the movable frame; a base is movably connected to the bottom end of the traction frame; and three combined bolts are installed inside the base.

[0010] In a preferred embodiment, the present invention can be further configured such that: two T-shaped sliders are fixedly installed on the inner wall of the movable frame, and the two T-shaped sliders are adapted to be inserted into two vertical slots, while the top of the reinforcing spring is adapted to bear pressure on the T-shaped sliders.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the power supply mechanism includes two bases movably mounted within two limiting frames, three fixing plates are installed within the bases, and a bottom plate is installed at the bottom of the three fixing plates. A main shaft is movably mounted within the bases and the bottom plate, a drive roller is fixedly mounted on the outside of the main shaft, and two symmetrically distributed vertical rods are inserted into the bases and the bottom plate, with pulleys movably mounted on the outside of the vertical rods.

[0012] In a preferred embodiment, the present invention may be further configured such that the power supply mechanism further includes a chassis fixedly installed outside one of the bases, a motor fixedly installed inside the chassis, and a first transmission belt drivingly connected to the motor and one of the main shafts.

[0016] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows: 1. This invention uses an external clamping mechanism inserted into exposed steel bars or wood on concrete. A rotating reciprocating screw drives a ring and two lever arms to extend relative to each other. Finally, two clamps and multiple longitudinal rollers quickly and centrally clamp the steel bars or wood. With the help of a power supply mechanism, a wire saw rotates at high speed. At this time, the steel bars or wood located in the middle of the protective cover can be quickly and safely cut off, further improving the flatness of the cut.

[0017] 2. This invention fully inserts the reinforcing bars or wood into the interior of the protective cover until the two fan-shaped plates at the bottom of the cover are pressed against the concrete. After the reinforcing bars or wood are clamped by the clamps and longitudinal rollers, the part of the reinforcing bars or wood to be cut will be forcibly straightened. This improves the safety of circumferential cutting of reinforcing bars or wood, and avoids the problem of waste or material ejection causing safety hazards to users.

[0018] 3. This invention installs an air intake hood inside the protective cover. As the wire saw rotates at high speed, one of the drive rollers and the main shaft drive the second transmission belt, which in turn drives the linkage components. Finally, the exhaust hood actively and directionally discharges the waste and dust generated during the cutting of steel bars or wood, thereby preventing waste or dust from polluting the air around the user.

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0022] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0023] The following describes, with reference to the accompanying drawings, some embodiments of a construction material circumferential cutting device provided by the present invention.

[0024] Example 1: Combination Figures 1 to 9As shown, the present invention provides a construction material circumferential cutting device, comprising a calibration clamping mechanism 100, a cutting distance control mechanism 200 installed on the calibration clamping mechanism 100, a power supply mechanism 300 installed between the calibration clamping mechanism 100 and the cutting distance control mechanism 200, and a wire saw 400 connected to the power supply mechanism 300. The calibration clamping mechanism 100 is used to calibrate and clamp steel bars or wood, thereby enhancing the safety of cutting steel bars or wood. The cutting distance control mechanism 200 is used to adjust the opening and closing of the power supply mechanism 300, thereby controlling the cutting depth of steel bars or wood. The power supply mechanism 300 is used to power the wire saw 400, thereby facilitating the cutting of steel bars or wood. The wire saw 400 is used to circumferentially cut the calibrated steel bars or wood.

[0025] The calibration clamping mechanism 100 includes a protective cover 110, on which two studs 1101 are fixedly mounted. A load-bearing pad 160 is mounted on each stud 1101. A reciprocating screw 170 is threaded onto the internal thread of the load-bearing pad 160. A ring 140 is movably mounted at the bottom end of the reciprocating screw 170. Two clamps are provided on the inner wall of the ring 140, and a lever arm 1401 is movably mounted on each clamp. A clamp seat 150 is movably mounted on each lever arm 1401. A uniformly distributed clamp is movably mounted within the clamp seat 150. The three longitudinal rollers 1501 of the cloth, two symmetrically distributed ring pads 1104 are fixedly installed on the two fan-shaped plate segments at the bottom of the cover 110, two symmetrically distributed vertical grooves are opened on the outer wall of the top tube segment of the cover 110, and a reinforcing spring 1102 is installed in the vertical groove. Two horizontal grooves are opened inside the cover 110, and a tension spring 1103 is fixedly connected to the inner wall of the horizontal groove. The other end of the tension spring 1103 is fixedly installed on the clamp 150. A horizontally placed limiting frame 130 is inserted into the fan-shaped plate segment at the bottom of the cover 110. An air intake shroud 120 is fixedly installed inside the protective cover 110. Two insertion holes 1202 are provided on one side of the air intake shroud 120. A guide pad 1201 is fixedly installed at the bottom of the air intake shroud 120, and the groove in the middle of the guide pad 1201 is adapted to and symmetrical with the through hole inside the protective cover 110. The number of limit frames 130 is two; The wire saw 400 is located within the gap between the two ring pads 1104.

[0026] Preferably, the protective cover 110 has an inverted T-shaped structure, and the tube section at the top of the protective cover 110 is used to provide stabilizing constraints for the upper half of the straightened steel bar or wood, so as to avoid abnormal shaking of the upper half of the steel bar or wood during cutting. The protective cover 110 has two symmetrically distributed inclined slots on both sides, and two symmetrically distributed limiting slots are provided inside the protective cover 110. The clamps of the two lever arms 1401 and the outer walls of the two clamps 150 all penetrate into the limiting slots. Under the elastic traction of the two tension springs 1103, the two clamps 150 will adhere to the inner wall of the protective cover 110, which facilitates the effective guiding path for steel bars or wood. In addition, the two fan-shaped plate segments at the bottom of the protective cover 110 can bear pressure on the concrete. As the reciprocating screw 170 rotates forward and pushes the ring sleeve 140 down, the two lever arms 1401 will extend relative to each other along the two limiting slots. The two clamps 150 and multiple longitudinal rollers 1501, which are compressed and contract inward, will quickly clamp and fix the steel bars or wood. At this time, after the two fan-shaped plate segments bear pressure on the concrete, the part of the steel bars or wood to be cut can be forcibly straightened and tightened, which is convenient to cooperate with the wire saw 400 to improve the flatness of the cut of the steel bars or wood.

[0027] Example 2: Combination Figures 4 to 7 As shown, based on Embodiment 1, the tangent adjustment mechanism 200 includes a cylinder 220 fixedly installed inside the protective cover 110, a movable frame 210 installed on the cylinder 220, and the movable frame 210 is movably installed outside the pipe section at the top of the protective cover 110. Two symmetrically distributed traction frames 230 are movably installed on the movable frame 210, and a base 240 is movably connected to the bottom end of the traction frame 230. Three combination bolts 250 are installed inside the base 240. Two T-shaped sliders are fixedly installed on the inner wall of the movable frame 210, and the two T-shaped sliders are adapted to be inserted into two vertical slots, while the top of the reinforcing spring 1102 is adapted to bear pressure on the T-shaped sliders.

[0028] Preferably, the cylinder 220 is fixed inside the cover 110 by welding, and the top end of the piston rod inside the cylinder 220 is fixedly installed inside the movable frame 210. The air pipe of the cylinder 220 is connected to the hose on the air pump of the outer cover. Gas is injected into the cylinder 220 through the air pump of the outer cover. Under the compression of the gas, the piston rod will drive the movable frame 210 and the two traction frames 230 to extend relative to each other. The two traction frames 230 after being extended at equal angles will push the two bases 240 to extend and retract synchronously, which is convenient for the power supply mechanism 300 to adapt and adjust the tension of the wire saw 400.

[0029] Example 3: Combination Figures 4 to 9As shown, in the above embodiment, the power supply mechanism 300 includes two bases 310 movably installed within two limiting frames 130. Three fixing plates 3102 are installed within each base 310, and a base plate 3101 is installed at the bottom of each fixing plate 3102. A main shaft 370 is movably installed within the bases 310 and base plate 3101. A drive roller 3701 is fixedly installed outside the main shaft 370. Two symmetrically distributed vertical rods 380 are inserted into the bases 310 and base plate 3101. A pulley 3801 is movably installed outside the vertical rods 380. A mechanism is fixedly installed outside one of the bases 240. The housing 340 has a motor 3401 fixedly installed inside. The motor 3401 and one of the spindles 370 are connected by a first transmission belt 350. A clamp 320 is fixedly installed outside another base 240. A linkage 3201 is movably installed inside the clamp 320. The linkage 3201 and the other spindle 370 are connected by a second transmission belt 360. An exhaust hood 330 is provided on the top of the linkage 3201. A protective pad 3301 is installed on the slot on the top of the exhaust hood 330. The two pipe sections of the exhaust hood 330 are adapted to pass through two insertion holes 1202. Pullers are installed on the rod segments of the motor 3401, the main shaft 370, and the linkage 3201. An impeller is fixedly installed on the top of the linkage 3201 rod segment, and the impeller is located inside the exhaust hood 330. Two annular washers are fixedly mounted on the outside of the pulley 3801. The drive roller 3701 has ring teeth in the middle, and the two annular washers are located at the top and bottom of the ring teeth to provide anti-detachment protection for the wire saw 400. Preferably, the column head at the top of the base 310 has three holes, and the combination bolts 250 are adapted to be installed in the holes. The top and bottom ends of the three fixing plates 3102 are respectively inserted into the fan-shaped plates of the base 310 and the bottom plate 3101. The semi-circular tube section of the base 310 has two rectangular slots, and the limiting frame 130 is adapted to be inserted into the two rectangular slots of the semi-circular tube section inside the base 310. Among them, the rod end inside the drive roller 3701 can be installed in the round holes inside the base 310 and the bottom plate 3101 respectively through bearings, while the rod segment inside the linkage 3201 can be movably installed in the clamp 320 through two bearings. As the motor 3401 starts and drives the first transmission belt 350 with a pulley on its internal transmission shaft, the other end of the first transmission belt 350 will assist in rotating one of the main shafts 370 and the drive roller 3701. The two drive rollers 3701, together with the tensioned wire saw 400, will rotate at high speed along the gap between the two ring pads 1104. The steel bars or wood located in the middle of the two fan-shaped plate sections at the bottom of the protective cover 110 can be quickly ring-cut. The waste and dust generated by the cutting of the steel bars or wood will be actively sucked in by the airflow in the cavity of the air intake hood 120 and the exhaust hood 330. The sucked-in waste and dust can be discharged in a direction to avoid polluting the air around the user. At the same time, another drive roller 3701 and another spindle 370 driven at the other end of the wire saw 400 will assist in the rotation of the second drive belt 360, which will drive the linkage 3201. Finally, the impeller in the linkage 3201 will continuously exhaust air to ensure that waste and dust can be continuously discharged.

[0030] The working principle and usage process of this invention: The wheel at the top of the reciprocating screw 170 is rotated in advance. As the reciprocating screw 170 rotates forward, the ring sleeve 140 is pulled and will be lifted up along the protective cover 110. The two lever arms 1401, which are movably installed on the two clamps on the inner wall of the ring sleeve 140, will stretch the two clamps 150 to move outward laterally. Finally, the two clamps 150 will fit against the inner wall of the protective cover 110. Then, the entire calibration clamping mechanism 100 is inserted along the steel bar or wood protruding from the concrete until the steel bar or wood extends into the interior of the protective cover 110. Then rotate the reciprocating screw 170 in reverse, and the reciprocating screw 170 will push the ring sleeve 140 down. The down movement of the ring sleeve 140 will push the two lever arms 1401 and the two clamps 150 to retract inward until the three longitudinal rollers 1501, which are movably installed in the clamps 150, clamp the steel bar or wood in the center, and the steel bar or wood can be quickly calibrated and clamped. Next, an external air pump is used to supply air to the inner cavity of cylinder 220 until the piston rod inside cylinder 220 drives the movable frame 210 and the two traction frames 230 to expand outward. The base 240 installed at the bottom of the traction frame 230, together with three combination bolts 250, will synchronously push the base 310 laterally. Finally, the two symmetrically distributed bases 310 will synchronously expand outward along the slide rails inside the two limiting frames 130. The wire saw 400, which is tensioned by the two bases 310 and the two drive rollers 3701, will then retract along the gap between the two ring pads 1104. After the motor 3401 is powered on and running, its An internal drive shaft and an external pulley drive a first drive belt 350, and the other end of the first drive belt 350 drives a main shaft 370 and a drive roller 3701. The wire saw 400, which is tensioned by the two drive rollers 3701, cuts the steel bars or wood along the gap between the two ring pads 1104. At the same time, the control calibration clamping mechanism 100 rotates along the clamped steel bars or wood until the guard 110 rotates around the multiple longitudinal rollers 1501. The high-speed rotating wire saw 400 can then quickly circumferentially cut the steel bars or wood. Meanwhile, as another drive roller 3701 drives another main shaft 370 to rotate, the second transmission belt 360 will drive the linkage 3201, and the impeller in the linkage 3201 will rotate at high speed along the inner cavity of the exhaust hood 330. The waste and smoke generated during the cutting of steel bars or wood will be transferred to the interior of the exhaust hood 330 through the cavity formed by the air intake hood 120 and the guide pad 1201. Finally, the waste and smoke will be directionally transferred to avoid causing large-scale pollution to the air around the user. In addition, the steel bars or wood in the middle of the protective cover 110 and the air intake hood 120 can be safely stored to avoid the safety hazards of the cut steel bars or wood to the user.

[0031] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
