Description

Technical Field

[0002] In building structures, steel structures are one of the main structures, which are mainly composed of steel beams, steel columns, steel trusses and other components made of profiled steel and steel plates. The characteristics of steel structures are high strength, light self-weight, good overall rigidity and strong deformation ability. Therefore, they are particularly suitable for building large-span, ultra-high and super-heavy buildings; the material has good homogeneity and isotropy, belongs to an ideal elastic body, and most conforms to the basic assumptions of general engineering mechanics; the material has good plasticity and toughness, can have a large deformation, can well withstand dynamic loads, and the construction period is short. When welding a combination of some steel plates, punching is often required at the corresponding positions designed on the drawings.

[0003] However, the current drilling machines have the following deficiencies:

[0004] 1. When drilling steel structures, the hole diameters and angles on steel structures for different uses are different. Although the inclination of the hole diameter angle of the steel structure can be changed on the existing market, the inclination angle cannot be monitored during the inclination and accurate positioning cannot be achieved for each angle.

[0005] 2. Anti-collapse design cannot be carried out for both hollow steel structures and solid steel structures during drilling.

Detailed implementation manners

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0035] Embodiment 1: Refer to Figure 1 -Figure 5 , including a base 1, and a positioning mechanism 2 is fixedly arranged on the top of the base 1 for fixing a steel member and driving it to rotate to adjust the drilling angle.

[0036] Refer to Figure 1 - Figure 2 , the positioning mechanism 2 includes a positioning plate 21, side plates 22, a first motor 23, a central rod 24, a cross plate 25, a reciprocating screw rod slide 26, a monitoring component 27 for monitoring the inclination angle, and a locking component 28 for locking the angle after the cross plate 25 is inclined. The positioning plate 21 is fixedly connected to the top of the base 1, the side plates 22 are fixedly connected to one side wall of the positioning plate 21, the central rod 24 is rotatably arranged between the side plates 22 and the positioning plate 21 through a bearing, the first motor 23 is fixedly connected to one side wall of the side plates 22, and the output end is fixedly connected to the central rod 24. The center of one side wall of the cross plate 25 is fixedly connected to the central rod 24. The number of the reciprocating screw rod slides 26 is two and they are respectively fixedly connected to both side walls of the cross plate 25. The monitoring component 27 is fixedly connected to one side wall of the positioning plate 21. The number of the locking components 28 is two groups and they are symmetrically arranged.

[0037] Refer to Figure 3 , the monitoring component 27 includes a circular frame 271, a first electric push rod 272, an abutting head 273, a pressing plate 274 and a first switch 275. The circular frame 271 is fixedly connected to one side wall of the positioning plate 21, and the circular frame 271 is concentric with the central rod 24. The first electric push rod 272 is fixedly connected to the inside of the central rod 24 and the output end is fixedly connected to the abutting head 273. One side wall of the pressing plate 274 is rotatably connected to the inside of the circular frame 271 through a rotating shaft and the first switch 275 is fixedly connected to the circular frame 271. The number of the first switches 275 and the pressing plates 274 is multiple and they are evenly arranged along the circumferential direction of the circular frame 271.

[0038] Refer to Figure 4 - Figure 5 , the locking component 28 includes a locking sleeve 281, a movable rod 282, a limiting plate 283, a locking plate 284 and an inclined abutting plate 285. The locking sleeve 281 is fixedly connected to the cross plate 25 and is rotatably arranged with the top of the movable rod 282 through a rotating shaft. A chute for the movable rod 282 to slide through is penetrated in the base 1. The limiting plate 283 is fixedly connected to the top of the base 1. The number of the inclined abutting plates 285 is multiple and they are fixedly connected to one side wall of the limiting plate 283 and are evenly distributed. The locking plate 284 is rotatably connected to the movable rod 282 through a one-way rotating shaft, and an opening for the locking plate 284 to be engaged with is formed on the inclined abutting plate 285.

[0039] In this embodiment: First, transfer the steel member to be drilled to the side of the device, and fix both ends of the steel member through the clamping plates on the reciprocating screw rod slide 26, as Figure 1As shown, the initial punching angle of the device is in a horizontal state. When it is necessary to change the angle of the steel member, start the first electric push rod 272 to drive the abutting head 273 to rise, so that the abutting head 273 abuts against the pressing plate 274. The pressing plate 274 rotates and abuts against the first switch 275. Thus, the first switch 275 sounds, indicating that the current state is the horizontal angle and the angle adjustment is about to start. Start the first motor 23, so that the first motor 23 drives the central rod 24 to rotate. When the central rod 24 rotates, it drives the abutting head 273 to rotate clockwise. During the rotation process, the abutting head 273 abuts against the pressing plates 274 at different angles, causing the first switches 275 at different angles to sound in sequence. Different first switches 275 represent different angles. Suppose it is necessary to drive the steel member to tilt 30 degrees. After the first switch 275 corresponding to the 30-degree angle sounds during the rotation, the first motor 23 stops moving. It can be distinguished by visual inspection, machine observation, or by setting different first switches 275 with voice announcements;

[0040] After the central rod 24 rotates a certain angle and stops, the rotated inclined angle is supported and locked by two locking assemblies 28, as Figure 2 shown. When the central rod 24 rotates clockwise, the left cross plate 25 moves upward, and the right cross plate 25 moves downward. The locking sleeves 281 at both positions move in the same direction as the cross plates 25 on both sides. Under the action of the rotating shaft, it drives the movable rod 282 to slide on the base 1. The left cross plate 25 moves upward, so that the left locking plate 284 is located below the movable rod 282, and the right side is above. The one-way rotation angle of the locking plate 284 is opposite to the moving direction of the movable rod 282. For example, when the left movable rod 282 moves upward, the locking plate 284 rotates downward and cannot rotate upward, while the inclined abutting plate 285 moves in the same direction as the movable rod 282. When the left movable rod 282 moves upward, the inclined abutting plate 285 is inclined upward. The working principle is as follows: When the cross plate 25 rises and drives the movable rod 282 to rise, the movable rod 282 rises and drives the locking plate 284 to rise, and rotates downward under the limit of the inclined abutting plate 285. After the central rod 24 rotates 30 degrees and stops, the locking plate 284 rises to the inclined abutting plate 285 at the corresponding angle, so that the opening on the locking plate 284 is engaged with the opening on the inclined abutting plate 285. Since the locking plate 284 cannot rotate upward, a supporting and locking effect is formed with the inclined abutting plate 285.

[0041] Embodiment 2:

[0042] Referring to Figure 6 - Figure 12 , the difference from Embodiment 1 is that: a first screw slide is fixedly provided on the base 1, and an anti-collapse mechanism 3 for preventing the collapse of the punching area of the steel member is slidably provided on the first screw slide.

[0043] Referring to Figure 7 -Figure 9 , the anti-collapse mechanism 3 includes an internal support component 31 and an external reinforcement component 32. The internal support component 31 includes a first multi-stage electric telescopic rod 311, a support box 312, a second motor 313, a first gear 314, a first toothed plate 315, and a support abutment plate 316.

The support abutment plate 316 is slidably connected to the inside of the support box 312 and is fixedly connected to the first toothed plate 315. Every two support abutment plates 316 in the horizontal direction are fixedly connected, and an opening is provided on the connected support abutment plate 316. The output end of the first multi-stage electric telescopic rod 311 is fixedly connected to one side of the outer wall of one of the support boxes 312.

[0044] Refer to Figure 10 - Figure 11 , the external reinforcement component 32 includes a second multi-stage electric telescopic rod 321, a fixed box 322, a pull-out plate 323, a bottom abutment plate 324, a top abutment plate 325, and an observation member 326 for observing whether the aperture of the drilling head is offset during drilling. The output end of the second multi-stage electric telescopic rod 321 is fixedly connected to one side of the outer wall of the fixed box 322. There are two pull-out plates 323, which are symmetrically and elastically slidably arranged up and down inside the fixed box 322. The bottom abutment plate 324 is fixedly connected to the bottom of one of the pull-out plates 323, and the top abutment plate 325 is fixedly connected to the top of the other pull-out plate 323. A round hole penetrates through the top abutment plate 325. There are four groups of observation members 326, which are uniformly arranged along the direction of the round hole. The tail end of the second multi-stage electric telescopic rod 321 is fixedly connected to the first multi-stage telescopic rod through a rod body, and an electric push rod is fixedly provided on the top of the slider on the first lead screw slide table, and the output end of the electric push rod is rotatably connected to the rod body through a rotating shaft.

[0045] The observation member 326 includes an observation plate 3261, a second toothed plate 3262, a second gear 3263, a connecting plate 3264, a detection frame 3265, a connecting finger rod 3266, a positioning slide plate 3267, and a second switch 3268. The observation plate 3261 is disposed in the circular hole, and a slot for the observation plate 3261 to slide is provided on the top abutting plate 325. The second toothed plate 3262 is fixedly connected to one side wall of the observation plate 3261, and a plurality of return springs are fixedly provided between one side wall of the observation plate 3261 and the inner wall of the top abutting plate 325. And a slot for the second toothed plate 3262 to slide is provided inside the top abutting plate 325. The number of the connecting plates 3264 is two and is fixedly arranged on the top of the top abutting plate 325. Both ends of the second gear 3263 are rotatably arranged on one side wall of the two connecting plates 3264 through bearings respectively, and the second gear 3263 is meshed with the second toothed plate 3262. The detection frame 3265 is fixedly connected to one side of the outer wall of one of the connecting plates 3264. The connecting finger rod 3266 is rotatably arranged on the outer wall of one of the connecting plates 3264 through a bearing and is fixedly connected to the second gear 3263. A slot for the positioning slide plate 3267 to slide is provided on the detection frame 3265, and the second switch 3268 is fixedly connected to the bottom of the second slide plate.

[0046] In this embodiment: When punching a steel member is required, as Figure 1 shown, in the horizontal state, the steel members on the market are hollow and solid. Through the internal support component 31 and the external strengthening component 32 in the anti-collapse mechanism 3, the inner hollow part and the outside of the steel member are supported synchronously respectively, so as to reduce and prevent the possibility of the steel member collapsing during punching. First, start the electric telescopic rod to drive the anti-collapse mechanism 3 to rise. After rising to move the anti-collapse mechanism 3 to the same height as the steel member, stop. Start the first screw slide table to drive the anti-collapse mechanism 3 to move to the port of the steel member and stop. Then, according to the punching position, start the multi-stage electric telescopic rod to drive the internal support component 31 and the external strengthening component 32 to move to the punching position respectively;

[0047] The bottom abutting plate 324 and the top abutting plate 325 are respectively adjusted to abut against the upper and lower surfaces of the steel member through the pulling plate 323. The second multi-stage electric telescopic rod 321 is started to drive the external strengthening assembly 32 to move to the drilling position. The internal support assembly 31 also moves the same distance through the first multi-stage telescopic rod and then stops. The second motor 313 is started to drive the first gear 314 to rotate. The first gear 314 drives the two gears to move in opposite directions, thereby driving the two support bottom plates to abut against the upper and lower parts of the steel member, improving the support effect and reducing collapse. When drilling, the observation member 326 can be used to observe whether the aperture of the drill head deviates during drilling. The deviation of the position of the drill head or the collapse of the steel member can both cause the aperture to deviate. Detection through the observation member 326 can effectively prevent the same problems from occurring in subsequent work and can timely adjust the components with problems. When the position of the drill head deviates or the steel member collapses, the drill head will squeeze the observation plate 3261, causing the observation plate 3261 to move and drive the second toothed plate 3262 to move. The movement of the second toothed plate 3262 drives the second gear 3263 to rotate. The rotation of the second gear 3263 drives the connecting finger rod 3266 to rotate. The position of the second switch 3268 can be confirmed by adjusting the position of the positioning slide plate 3267. For example, when the connecting finger rod 3266 moves, it means that the aperture has deviated, and the position of the second switch 3268 is as Figure 11 shown in the initial position. Suppose that when the position of the connecting finger rod 3266 is more than ten degrees outside, it means that the aperture has deviated, and the positioning slide plate 3267 is driven to slide to the position of 11 degrees to lock the position of the second switch 3268. After setting, when the connecting finger rod 3266 rotates and triggers the second switch 3268, it means that the aperture has deviated at this moment.

[0048] Embodiment Three:

[0049] Refer to Figure 13 , the difference from Embodiment One is that: a second lead screw slide is fixedly provided on the base 1, and a detection mechanism 4 for detecting whether the drilling position of the steel member collapses is slidably provided on the second lead screw slide.

[0050] The detection mechanism 4 includes a support plate 41, a sliding plate 42, a support seat 43, an abutting seat 44, a detection plate 45 and a third switch 46. The bottom of the support plate 41 is fixedly connected to the slider on the second lead screw slide. The sliding plate 42 is slidably connected to the inside of the support plate 41 through a spring and extends out of the support plate 41. The top of the sliding plate 42 is fixedly connected to the support seat 43. The support seat 43 is rotatably connected to the abutting plate through a rotating shaft, and springs are fixedly connected to the four corners between the support seat 43 and the abutting plate. A slot for the detection plate 45 to slide is opened on the outer wall of the sliding plate 42 and locked by a bolt. The third switch 46 is fixedly connected to the top of the support plate 41.

[0051] In this embodiment: After the detection mechanism 4 is driven by the second lead screw slide table to move to the same position as the external strengthening component 32 and stops, the top of the abutting seat 44 abuts against the bottom abutting plate 324. When the steel member is inclined, the abutting seat 44 still abuts through rotation around the rotating shaft. When the steel member collapses, the abutting seat 44 is squeezed, driving the sliding plate 42 to slide inside the support plate 41. However, normal floating occurs during the drilling process, so the pressing distance can be set, the position of the detection plate 45 and the distance from the detection plate 45 to the third switch 46 can be adjusted, and the position of the detection plate 45 is locked by bolts. When the detection plate 45 triggers the third switch 46 during pressing, it indicates that a collapse has occurred.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
