[0024] like Figure 7 and Figure 8 As shown, the cooling mechanism includes a third elastic telescopic rod 505, and the third elastic telescopic rod 505 is symmetrically fixed in the outer shell 305 through a support plate, and the telescopic end of the third elastic telescopic rod 505 is fixed with an L-shaped rod 506 used in conjunction with the connecting plate 502, and the lower part of the L-shaped rod 506 is slidingly connected to the dust box 301 and the lifting plate 302 respectively, and a fan 507 is installed on one side of the L-shaped rod 506.

[0025] like Figure 6 and Figure 7 As shown, it also includes a support rod 601, the support rod 601 is symmetrically fixed in the outer shell 305, and a rotating shaft 602 is rotatably connected to the support rod 601. The first gear 206 is fixed to one end of the rotating shaft 602, and the other end of the rotating shaft 602 is fixed to the second gear 603. The bottom of the dust box 301 is fixed to a third rack 604 meshing with the second gear 603. When the first rack 204 and the second rack 205 are lowered or raised, the second gear 603 can drive the dust box 301 to move through the third rack 604.

[0026] Initially, the first rack 204 is meshed with the first gear 206, and the steel structure is Figure 1The base 1 is placed on the lower side of the steel structure, and then the shell 305 is placed on the base 1. At this time, the steel structure is located between the two dust boxes 301. Then, the position of the lifting plate 302 is adjusted according to the model of the steel structure. First, the staff pulls it horizontally through the handle on the first elastic telescopic rod 303, and the first elastic telescopic rod 303 drives the limiting pin 304 to disengage from several limiting grooves on the shell 305. Then, the first elastic telescopic rod 303 is pulled upward, thereby lifting the two lifting plates 302 upward. The lifting plate 302 pulls the connecting block 401 to slide upward through the second elastic member between the lifting plate 302 and the connecting block 401, and the connecting block 401 drives the adjacent L-shaped plate 403 to lift upward through the second elastic telescopic rod 402, so that the L The L-shaped plate 403 is at the center of the vertical direction of the steel structure, and then the first elastic telescopic rod 303 is pushed horizontally, the first elastic telescopic rod 303 contracts and drives the limiting pin 304 to be stuck in several limiting grooves on the shell 305, thereby limiting the lifting plate 302 and the L-shaped plate 403, and then the first electric push rod 501 is started, the telescopic end of the first electric push rod 501 drives the connecting plate 502 to descend, the connecting plate 502 drives the elastic telescopic frame 203 to descend, the elastic telescopic frame 203 drives the elastic sliding shaft 202, the first rack 204 and the second rack 205 thereon to descend, and the elastic sliding shaft 202 slides downward along the first guide groove 207. Since the elastic force of the elastic telescopic frame 203 is greater than the elastic force of the first elastic member, the first rack 204 can pass The first gear 206 drives the rotating shaft 602 to rotate, and the rotating shaft 602 drives the third rack 604 to move through the second gear 603, so that the two dust boxes 301 move closer to each other, and the first elastic member between the dust box 301 and the shell 305 is extended by force, and the two dust boxes 301 drive the two lifting plates 302 to move closer to each other, and then the two adjacent second adaptation plates 405 contact with the steel structure, and the second adaptation plates 405 are blocked by the steel structure and slide into the slide groove of the first adaptation plate 404, so that the fourth elastic member is forced to shrink, and then the inclined surface of the first adaptation plate 404 contacts with the steel structure, and the steel structure squeezes the inclined surface of the first adaptation plate 404, so that the two adjacent first adaptation plates 404 slide closer to each other, and the third elastic member is forced to shrink. After the top surface or bottom surface of 04 contacts the inner wall of the steel structure, the second adaptation plate 405 is freed from the restriction and released to slide through the fourth elastic member and fits with the steel structure. At this time, the two dust boxes 301 and the two lifting plates 302 contact each other and completely surround the cutting part of the steel structure. Through the above steps, the dustproof mechanism can adapt to different steel structures, so as to perform cutting. Subsequently, the connecting plate 502 contacts and squeezes the top surfaces of the two L-shaped rods 506. The L-shaped rod 506 is forced to drive the telescopic end of the third elastic telescopic rod 505 to extend downward, and drives the fan 507 thereon to fall downward. At this time, the fan 507 is started. When the subsequent cutting work is performed, the debris generated by the cutting can be effectively prevented from splashing, and the fan 507 is used to blow air to the cutting section of the steel structure.Since the fan 507 is inclined, the air flow blown by the fan 507 is directed obliquely downward. While the air flow blown by the fan 507 discharges the heat generated at the cutting part of the steel structure obliquely downward, it can also blow the debris obliquely downward, thereby achieving the effects of cooling and collecting the debris. Since the cutting part of the steel structure is completely surrounded at this time, blowing by the fan 507 can maximize the air cooling effect in a limited space, and can cool the cutting section of the steel structure, the cutting saw for cutting the steel structure, and the debris generated during cutting, preventing subsequent workers from being scalded when handling the steel structure or dealing with the debris. Embodiment 2

[0027] As Figure 7 shown, it further includes a cutting assembly 701. The telescopic end of the first electric push rod 501 is provided with a cutting assembly 701, and vertical rods 702 are symmetrically and fixedly connected to the bottom of the connecting plate 502.

[0028] As Fig. 9 With Fig.10 shown, it further includes a polishing mechanism. The polishing mechanism includes a collecting hopper 801. The collecting hopper 801 is fixedly connected to the bottom of the base 1 in a penetrating manner. Extension rods 802 are symmetrically and fixedly connected inside the collecting hopper 801. The telescopic ends of the two extension rods 802 are jointly fixedly connected to a C-shaped seat 803. Two groups of driving components 804 are symmetrically arranged on the C-shaped seat 803. The driving component 804 is composed of a micro motor, a tension pulley, a first belt pulley, a second belt pulley, a third belt pulley, a transmission belt and a vertical shaft. Among them, the micro motor and the tension pulley are installed on the C-shaped seat 803, the tension pulley is located on one side of the micro motor, the first belt pulley is fixedly connected to the output shaft of the micro motor, the second belt pulley and the third belt pulley are located on one side of the tension pulley, the transmission belt is wound around the tension pulley, the first belt pulley, the second belt pulley and the third belt pulley, and vertical shafts are fixedly connected to the tops of the second belt pulley and the third belt pulley. A sand belt 805 is wound around the vertical shafts. The vertical area of the sand belt 805 is larger than the cutting section area of the steel structure. Elastic wedge-shaped blocks 806 are symmetrically and slidably connected inside the C-shaped seat 803, and wedge-shaped grooves for cooperating with the elastic wedge-shaped blocks 806 are provided on the vertical rods 702.

[0029] As Fig.10 With Fig.11 shown, the polishing mechanism further includes guide posts 901. Guide posts 901 are symmetrically and fixedly connected to the C-shaped seat 803. A T-shaped plate 902 is slidably connected to the guide posts 901. A fifth elastic member is arranged between the T-shaped plate 902 and the C-shaped seat 803. The fifth elastic member is a return spring. A rectangular plate 903 is fixedly connected to one side of the T-shaped plate 902. Oblique grooves are symmetrically provided on one side of the rectangular plate 903. A sliding shaft 904 is slidably connected inside the oblique grooves. Two groups of support plates are symmetrically and slidably connected to the C-shaped seat 803. Each group has two. The sliding shaft 904 is fixedly connected to the two groups of support plates. The second belt pulley and the third belt pulley in the driving component 804 are respectively rotatably connected to the two groups of support plates.

[0030] As Fig.12 shown, it further includes a guide rod 1001. A convex shaft is fixedly connected to one side of the elastic wedge block 806. A sliding groove for cooperating with the convex shaft is provided on the U-shaped seat 803. Guide rods 1001 for cooperating with the convex shaft are symmetrically and fixedly connected to the inner wall of the outer shell 305. When the convex shaft contacts the guide rod 1001, it can drive the elastic wedge block 806 to slide.

[0031] As Figure 1 with Fig.13 shown, it further includes a rotating frame 1101. The bottom of the base 1 is rotatably connected to the rotating frame 1101. Two groups of movable shafts 1102 are movably connected to the rotating frame 1101. Each group has two. A roller is rotatably connected to each movable shaft 1102. The rollers are used to be clamped into the steel structure. Two groups of clamping strips 1103 for cooperating with the outer shell 305 are fixedly connected to the top of the base 1. Corresponding pin holes are provided on both the clamping strip 1103 and the outer shell 305, and a pin is inserted into the pin holes.

[0032] When assembling the overall device, first pull two adjacent movable shafts 1102 away from each other, then the staff lift the rotating frame 1101 to the steel structure, and then push two adjacent movable shafts 1102 close to each other to reset. At this time, the rollers on the movable shafts 1102 are clamped into the steel structure and contact it. Then, the bottom end of the outer shell 305 is clamped into the two groups of clamping strips 1103, and a pin is inserted into the pin holes of the outer shell 305 and the two groups of clamping strips 1103, thus completing the assembly of the base 1 and the outer shell 305. When it is necessary to adjust the position of the overall device, pushing the rotating frame 1101 can move the position of the overall device through the rollers on the movable shafts 1102.

[0033] Since this device is an assembled structure, after the base 1 and the outer shell 305 are assembled, it is necessary to adjust the angle of the outer shell 305 so that the cutting saw in the cutting assembly 701 (the cutting assembly 701 is composed of a driving motor and a cutting saw, and the prior art will not be elaborated) is in a cross state with the steel structure. When the telescopic end of the first electric push rod 501 extends, it drives the driving motor in the cutting assembly 701 to descend, and the connecting plate 502 drives the vertical rod 702 to descend. At the same time, the second electric push rod 503 is started. The telescopic end of the second electric push rod 503 drives the positioning frame 504 to descend to extrude the steel structure. Since the steel structure is heavy, the outer shell 305 rotates. Affected by the structure of the positioning frame 504, the outer shell 305 extrudes the two groups of clamping strips 1103 to make the base 1 rotate around the connection point of the rotating frame 1101. After the outer shell 305 rotates, the cutting saw in the cutting assembly 701 is in a cross state relative to the steel structure. Through the above steps, accurate positioning of the cutting saw can be achieved, and then the driving motor is started. The output shaft of the driving motor drives the cutting saw to rotate at a high speed to cut the steel structure.

[0034] When the two dust-proof boxes 301 come into contact with each other, the cutting saw in the cutting assembly 701 starts to cut when it contacts the steel structure. The debris generated by the cutting is affected by the airflow blown by the fan 507 and falls into the collection hopper 801. Since the groove depth of the second guide groove 208 is greater than that of the first guide groove 207, at this time, the elastic sliding shaft 202 slides to the bottom of the first guide groove 207 and enters the second guide groove 208. At this time, the telescopic end of the first electric push rod 501 continues to extend, driving the cutting saw to descend. The elastic sliding shaft 202 contacts the bottom end of the second guide groove 208 and cannot move further, thereby causing the elastic telescopic frame 203 to contract. After the cutting saw finishes cutting the steel structure, the steel structure is cut into two pieces. The bottom end of the vertical rod 702 moves to the corresponding elastic wedge block 806 and squeezes it. The elastic wedge block 806 contracts under the force. When the wedge groove on the vertical rod 702 is aligned with the elastic wedge block 806, the elastic wedge block 806 releases and resets and snaps into the wedge groove. Then the telescopic end of the first electric push rod 501 contracts and resets, thereby causing the elastic sliding shaft 202 to slide upward. At this time, the elastic sliding shaft 202 first slides obliquely upward along the second guide groove 208. During this process, the elastic sliding shaft 202 drives the first rack 204 and the second rack 205 to move horizontally through the elastic telescopic frame 203. After the first rack 204 moves, it disengages from the first gear 206. At this time, the first gear 206 is released from the restriction, thereby enabling the third rack 604 to move. The first elastic member between the dust-proof box 301 and the outer shell 305 contracts, causing the dust-proof box 301 to reset and vibrate. At this time, the debris in the dust-proof box 301 falls into the collection hopper 801 due to the vibration. Subsequently, the second rack 205 meshes with the first gear 206, and then the elastic sliding shaft 202 slides vertically upward, thereby enabling the two dust-proof boxes 301 and the two lifting plates 302 to cooperate with each other to completely surround the cutting part of the steel structure, so as to prevent dust from flying out when the polishing mechanism polishes the cutting section of the steel structure. At the same time, the vertical rod 702 squeezes the bottom surface of the elastic wedge block 806 through the wedge groove on it. The elastic wedge block 806 is driven by the force to lift the U-shaped seat 803 upward. At this time, the extension rod 802 extends, and the U-shaped seat 803 drives the driving assembly 804 and the sand belt 805 on it to lift upward. At this time, the micro motor in the driving assembly 804 is started. The output shaft of the micro motor drives the first belt pulley to rotate at high speed. The first belt pulley drives the second belt pulley and the third belt pulley to rotate at high speed through the transmission belt. The second belt pulley and the third belt pulley respectively drive the two sand belts 805 to rotate at high speed through the vertical shafts on them, thereby polishing the cutting sections of the two steel structures. After the T-shaped plate 902 lifts upward and contacts the bottom surface of the corresponding dust-proof box 301, the T-shaped plate 902 is blocked and slides downward along the guide post 901. The fifth elastic member between the T-shaped plate 902 and the U-shaped seat 803 contracts under the force and drives the rectangular plate 903 to slide downward. The inclined groove on the rectangular plate 903 squeezes the sliding shaft 904 in it. The sliding shaft 904 slides under the force, causing the adjacent two support plates to slide away from each other.Furthermore, the adjacent second pulley and third pulley drive the two abrasive belts 805 away from each other through the vertical shafts thereon. The movement of the two abrasive belts 805 can better polish the burrs on the edges of the cutting sections of the two steel structures, thereby improving the polishing effect on the cutting sections of the steel structures.

[0035] When the top of the abrasive belt 805 crosses the cutting section of the steel structure, the polishing of the cutting section of the steel structure has been completed at this time. Subsequently, the convex shaft on the elastic wedge block 806 contacts the adjacent guide rod 1001, and the elastic wedge block 806 slides along the lower inclined surface of the guide rod 1001. After the elastic wedge block 806 slides, it disengages from the wedge-shaped groove on the vertical rod 702. At this time, the C-shaped seat 803 loses support and descends, driving the polishing mechanism to descend and reset. Thus, the work of the overall device is completed. Through the above steps, the cutting section of the steel structure can be polished while the cutting is completed, enabling the steel structure to directly carry out welding or assembly work, effectively improving the work efficiency.

[0036] The above are only embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present invention.
