Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Embodiment 1:

[0028] like Figures 1 to 6As shown, the present invention provides a technical solution for a clamping and punching device for processing a bridge steel structure: it includes a base plate seat 1, the upper surface of the base plate is provided with a plurality of guide slots, and each guide slot is provided with a clamping and positioning mechanism 4, the upper surface of the base plate seat 1 is provided with a plurality of hydraulic cylinders 2, and the top surface of the telescopic rod of the hydraulic cylinder 2 is provided with a supporting top plate 3, the lower surface of the supporting top plate 3 is provided with a punching mechanism, and the clamping and positioning mechanism 4 includes a bidirectional spiral screw 41, a screw slider 42, a clamping block 43, and a locking bolt. 44, electric push rod 45, pulley 46 and driving belt 47, the bidirectional screw 41 is rotatably arranged in the guide slide groove, and the bidirectional screw 41 is symmetrically sleeved with a screw slider 42 through a screw nut, the upper surface of the screw slider 42 is provided with a threaded hole 421, and the upper surface of the screw slider 42 is swingably provided with a clamping block 43, the clamping block 43 is locked and fixed on the upper surface of the clamping block 43 by a locking bolt 44, and the bottom end of the locking bolt 44 is threadedly connected in the threaded hole 421, the bidirectional Both ends of the spiral screw 41 are connected to the telescopic rod end faces of the electric push rod 45, and the fixed rod of the electric push rod 45 is rotatably arranged on the groove walls on both sides of the guide slide groove, and a pulley 46 is fixedly sleeved on the outer wall of the fixed rod of the electric push rod 45 extending from the rear side of the base plate seat 1, and a driving belt 47 is sleeved on the outer ring surface of the pulley 46, and a driving motor is fixed on the left side of the base plate seat 1, and the pulley 46 fixed on the output shaft of the driving motor is connected to the driving belt 47 for transmission. When working, when it is necessary to punch holes in the bridge steel structure to facilitate the later assembly of the bridge steel structure, the existing punching device can only punch holes in standard straight steel structures, and the bridge is not only built with straight steel structures during construction, but also with a large number of special-shaped steel structures, such as S-shaped or arc-shaped steel structures. Obviously, the existing punching device cannot punch holes for steel structures of this shape, and it is also impossible to perform anti-skid and deflection treatment on special-shaped steel structures when punching holes.Therefore, the present invention is designed to set multiple sets of clamping and positioning mechanisms 4 on the upper surface of the base plate seat 1. When it is necessary to clamp and drill the S-shaped steel structure, the staff can control the driving motor on the side of the base plate seat 1 through the PLC control system, so that the driving motor can drive multiple pulleys 46 to rotate through the driving belt 47, and the pulley 46 will drive the bidirectional spiral screw 41 to rotate through the electric push rod 45 on one side, so that the symmetrical screw sliders 42 in each guide slot can move closer to each other, and the distance between the symmetrical screw sliders 42 is controlled to be greater than the width of the steel structure. At this time, the driving motor stops working, and the person then controls the electric push rod 45 in each guide slot to work, so that the telescopic rod of the electric push rod 45 can push the bidirectional spiral screw rod 41 to move in the guide slot, thereby facilitating the adjustment of the screw slider 42 set in each guide slot on the upper surface of the base plate seat 1 to be the same S shape as the S-shaped steel structure, and then the staff puts the steel structure into the upper surface of the base plate seat 1, so that the clamping blocks 43 on the upper surface of the symmetrical screw slider 42 after adjustment can be located on both sides of the steel structure. Since the S-shaped steel structure has an arc surface, at this time, the staff can tighten the screw slider 42 by turning the locking bolt 4 4. Adjust the clamping block 43 on the upper surface of the screw slider 42 to be in an inclined state and aligned with the arc surface of the steel structure, and then rotate the locking bolt 44 in the opposite direction so that the clamping block 43 can be fixed on the screw slider 42. Then the staff controls the driving motor so that the multiple pulleys 46 can drive the bidirectional spiral screw 41 to rotate through the electric push rod 45, thereby driving the clamping block 43 adjusted to the inclined state to clamp and fit tightly on the two sides of the S-shaped steel structure, thereby clamping and fixing the S-shaped steel structure to prevent the punching mechanism from drilling holes in the S-shaped steel structure in sequence due to the existing The punching device cannot effectively clamp the S-shaped steel structure, which causes the S-shaped steel structure to deviate or slip during punching, thereby affecting the punching quality of the steel structure; when the S-shaped steel structure is punched, the telescopic rod of the hydraulic cylinder 2 is controlled to rise, so that the punching mechanism rises above the steel structure, and then the side drive motor of the bottom plate seat 1 is controlled to work, so that the multiple pulleys 46 can drive the multiple bidirectional screw rods 41 to rotate in the opposite direction, so that the symmetrical clamping blocks 43 can be disengaged from the two sides of the steel structure, so as to facilitate the removal of the punched S-shaped steel structure. ;

[0029] As an embodiment of the present invention, an elastic rubber layer 5 is provided on the inner side of the clamping block 43, and a corrugated groove is provided on the inner side of the elastic rubber layer 5; during operation, when the adjusted symmetrical clamping block 43 moves toward the two side surfaces of the steel structure for clamping, the elastic rubber layer 5 provided on the inner side of the clamping block 43 will clamp and contact the two side surfaces of the steel structure, so that the elastic rubber layer 5 can play a role of elastic buffering, preventing the symmetrical clamping block 43 from being damaged or deformed due to excessive clamping force, and the corrugated groove is provided on the inner side of the elastic rubber layer 5 to increase the friction force of the clamping block 43 and the side surface of the steel structure. At the same time, the elastic rubber layer 5 can also be deformed under the action of the extrusion force, thereby increasing the clamping contact area between the clamping block 43 and the arc surface of the steel structure, which can further prevent the steel structure from slipping or deflecting when drilling.

[0030] As an embodiment of the present invention, a vertical T-shaped block 51 is provided on the side where the elastic rubber layer 5 and the clamping block 43 are in contact, and a vertical T-shaped slot 431 is provided on the side where the clamping block 43 and the elastic rubber layer 5 are in contact. The T-shaped block 51 is slidably engaged in the T-shaped slot 431, and the vertical T-shaped slot 431 is below the head of the locking bolt 44. When working, when the elastic rubber layer 5 on the side of the clamping block 43 continuously clamps different steel structures, the elastic rubber layer 5 will be worn. Therefore, the present invention will By means of the cooperation between the T-shaped block 51 and the T-shaped slot 431, the rubber layer 5 can be detachably mounted on the side of the clamping block 43, thereby facilitating the replacement of the worn elastic rubber layer 5. Meanwhile, the slidingly engaged T-shaped block 51 and the T-shaped slot 431 are located below the head of the locking bolt 44, so that when the locking bolt 44 locks the clamping block 43 on the screw slider 42, the elastic rubber layer 5 can also be locked and fixed on the side of the clamping block 43, thereby achieving buffering, anti-skid clamping and fixation of the steel structure.

[0031] As an embodiment of the present invention, the punching mechanism includes a driving guide assembly 6 and a driving assembly 7, the driving guide assembly 6 includes a T-shaped slider 61, an L-shaped block 62 and an aluminum alloy guide rail 63, a plurality of T-shaped slide grooves 31 are provided on the lower surface of the support top plate 3, and a T-shaped slider 61 is slidably arranged in each T-shaped slide groove 31, an electric push rod 45 is fixedly arranged on the side wall of the T-shaped slide groove 31, and the telescopic rod end face of the electric push rod 45 is connected to the side of the T-shaped slider 61, the two side faces of the L-shaped slider are connected to the L-shaped block 62, and the support An aluminum alloy guide rail 63 is provided on the lower surface of the top support plate 3, and the cross section of the aluminum alloy guide rail 63 is an I-shaped structure. The upper side horizontal plate of the aluminum alloy guide rail 63 is slidably engaged on both sides of the lower surface of the L-shaped block 62, and a driving component 7 is slidably provided on the lower side horizontal plate of the aluminum alloy guide rail 63. During operation, when it is necessary to drive the driving component 7 to punch holes in the S-shaped steel structure that is clamped and fixed, it is necessary to first control the driving guide component 6 to have the same shape as the S-shaped steel structure, and then the driving component 7 can be driven in an S-shaped linear manner to punch holes in the steel structure. Punching process, therefore, at this time, the staff controls the multiple electric push rods 45 set inside the support top plate 3 to work through the PLC control system, so that the telescopic rods of the electric push rods 45 can drive the multiple T-shaped sliders 61 to slide back and forth in the multiple T-shaped slide grooves 31, and because the two side surfaces of the T-shaped sliders 61 are engaged with the aluminum alloy guide rails 63 through the L-shaped clamping blocks 62, the sliding of the multiple T-shaped sliders 61 in the multiple T-shaped slide grooves 31 will drive the aluminum alloy guide rails 63 with a certain elastic deformation to transform into an aluminum alloy guide rail with an S-shaped structure on the lower surface of the support top plate 3 63, and then the driving component 7 will move on the aluminum alloy guide rail 63 with an S-shaped structure, thereby realizing the punching processing of different positions on the S-shaped steel structure; and when it is necessary to punch holes in steel structures of other shapes, the steel structures of other shapes are first clamped and fixed on the upper surface of the base plate seat 1 by the clamping and positioning mechanism 4, and then the movement of multiple T-shaped sliders 61 on the supporting top plate 3 is controlled to make the aluminum alloy guide rail 63 able to change into a corresponding shape, thereby facilitating the driving component 7 to move on the aluminum alloy guide rail 63, and realizing the punching processing of the steel structure of the corresponding shape.

[0032] As an embodiment of the present invention, the driving assembly 7 includes a guide wheel 71, a rotating shaft rod 72, a connecting cross plate 73, a mounting box 74 and a drill bit 75. The guide wheel 71 is symmetrically rollingly arranged on the upper surface of the lower cross plate of the aluminum alloy guide rail 63, and the outer ring surface of the guide wheel 71 is in contact with the vertical plate surface of the aluminum alloy guide rail 63. The guide wheel 71 is symmetrically connected with a rotating shaft rod 72, and the lower end surface of the symmetrical rotating shaft rod 72 is rotatably arranged on the connecting cross plate 73. The connecting cross plate 73 is located on the lower surface of the lower cross plate of the aluminum alloy guide rail 63, and the connecting cross plate 73 is fixedly arranged. The output shaft of the driving motor is connected to the rotating shaft rod 72, and a mounting box 74 is fixed to the lower surface of the connecting cross plate 73, and a drilling motor is arranged inside the mounting box 74, and a drill bit 75 is arranged on the lower surface of the mounting box 74, and the drill bit 75 is connected to the output shaft of the drilling motor; the outer ring surface of the guide wheel 71 is wrapped with a wear-resistant layer; when working, the wear-resistant layer can protect the guide wheel 71 from wear; when the aluminum alloy guide rail 63 changes to the same shape as the steel structure, the staff controls the driving motor fixed on the connecting cross plate 73 to work, so that the output shaft of the driving motor can The guide wheel 71 is driven to rotate by the rotating shaft rod 72. At this time, since the symmetrical guide wheel 71 is located on the upper surface of the horizontal plate at the lower end of the aluminum alloy guide rail 63, the rotation of the guide wheel 71 will move along the deformed aluminum alloy guide rail 63, and then the installation box 74 and the drill bit 75 at the bottom of the connecting horizontal plate 73 can be moved, so that the drill bit 75 can move above the S-shaped steel structure in an S-shaped linear manner. When the drill bit 75 moves to the position of the steel structure corresponding to the hole to be punched, the telescopic rod of the hydraulic cylinder 2 is controlled to contract, so that it drives the supporting top plate 3 and the drill bit 75 to move downward, thereby facilitating the installation of the box 74. The internal drilling motor drives the drill bit 75 to perform the drilling operation. When the drilling is completed, the telescopic rod of the hydraulic cylinder 2 extends to disengage the drill bit 75 from the drill hole, and then the guide wheel 71 continues to rotate, driving the drill bit 75 to continue to move to the next position along the aluminum alloy guide rail 63 for drilling. The symmetrical guide wheel 71 is installed on the connecting cross plate 73 through the rotating shaft rod 72, and the connecting cross plate 73 is located below the aluminum alloy guide rail 63, which can prevent the guide wheel 71 from falling from the cross plate below the aluminum alloy guide rail 63, thereby affecting the drill bit 75 from safely drilling the aluminum alloy guide rail 63.

[0033] As an embodiment of the present invention, a buffer groove 731 is provided on the upper surface of the connecting cross plate 73, and a buffer rubber layer 76 is provided in the buffer groove 731. A plurality of balls 8 are provided on the upper surface of the buffer rubber layer 76 in a rolling manner, and the balls 8 are in rolling contact with the lower surface of the lower cross plate of the aluminum alloy guide rail 63. When the drill bit 75 is driven by the drilling motor to drill the steel structure, vibration will be generated between the drill bit 75 and the steel structure, and at this time, the drill bit 75 will transmit the vibration force to the connecting cross plate 73. Therefore, when the connecting cross plate 73 is connected, the vibration force will be transmitted to the connecting cross plate 73. A buffer rubber layer 76 is provided at the position where the upper surface of the cross plate 73 contacts the aluminum alloy guide rail 63, which can play a role in buffering and shock absorption, and prevent the vibration impact force received by the connecting cross plate 73 from directly acting on the lower side of the aluminum alloy guide rail 63, causing deformation of the aluminum alloy guide rail 63. At the same time, the multiple balls 8 provided on the upper surface of the buffer rubber layer 76 can play a role in rolling friction when the connecting cross plate 73 slides on the lower surface of the aluminum alloy guide rail 63, and prevent the connecting cross plate 73 from sliding on the lower surface of the aluminum alloy guide rail 63 for a long time and causing wear.

[0034] As an embodiment of the present invention, multiple hydraulic cylinders 2 are arranged along the four corners of the base plate seat 1, and the top end surface of the telescopic rod of each hydraulic cylinder 2 is detachably connected to the supporting top plate 3; the base plate seat 1 and the supporting top plate 3 are provided with arc chamfers; the lower surface of the base plate seat 1 is provided with multiple supporting legs, and the multiple supporting legs are used to support and install the base plate seat 1; when working, the telescopic rod of the hydraulic cylinder 2 is detachably connected to the supporting top plate 3, so that the staff can remove the large S-shaped or arc-shaped steel structure by disassembling the supporting top plate 3, and then directly use the hoisting method to clamp and fix it on the base plate seat 1 through the clamping and positioning mechanism 4, and then continue to install the supporting top plate 3 on the telescopic rod of the hydraulic cylinder 2, so that the supporting top plate 3 can drive the drill bit 75 to perform drilling operations.

[0035] Working principle: when it is necessary to clamp and drill holes in the S-shaped steel structure, the staff can control the drive motor on the side of the base plate 1 through the PLC control system, so that the drive motor can drive multiple pulleys 46 to rotate through the drive belt 47, and the pulley 46 will drive the bidirectional spiral screw 41 to rotate through the electric push rod 45 on one side, so that the symmetrical screw sliders 42 in each guide slot can move close to each other, and the distance between the symmetrical screw sliders 42 is controlled to be greater than the width of the steel structure. At this time, the drive motor stops working, and the staff then controls the electric push rod 45 in each guide slot to work, so that the telescopic rod of the electric push rod 45 can push the bidirectional spiral screw 41 to move in the guide slot, so that The screw slider 42 set in each guide slide groove is adjusted on the upper surface of the base plate seat 1 to be the same S shape as the S-shaped steel structure, and then the staff puts the steel structure into the upper surface of the base plate seat 1, so that the clamping blocks 43 on the upper surface of the screw slider 42 that are symmetrical after adjustment can be located on both sides of the steel structure. Since the S-shaped steel structure has an arc surface, at this time, the staff can adjust the clamping blocks 43 on the upper surface of the screw slider 42 to be in an inclined state and aligned with the arc surface of the steel structure by rotating the locking bolts 44, and then rotate the locking bolts 44 in the opposite direction so that the clamping blocks 43 can be fixed on the screw slider 42, and then the staff controls the driving motor so that the multiple pulleys 46 can drive the bidirectional spiral screw 41 to rotate through the electric push rod 45. Then, the clamping blocks 43 adjusted to an inclined state can be clamped and fitted on both sides of the S-shaped steel structure, thereby clamping and fixing the S-shaped steel structure. Then, the staff controls the multiple electric push rods 45 arranged inside the support top plate 3 through the PLC control system, so that the telescopic rods of the electric push rods 45 can drive the multiple T-shaped sliders 61 to slide back and forth in the multiple T-shaped slide grooves 31. Since the two sides of the T-shaped sliders 61 are clamped on the aluminum alloy guide rails 63 through the L-shaped clamping blocks 62, the sliding of the multiple T-shaped sliders 61 in the multiple T-shaped slide grooves 31 will drive the aluminum alloy guide rails 63 with a certain elastic deformation to transform into the aluminum alloy guide rails 63 with an S-shaped structure on the lower surface of the support top plate 3. Then, the staff controls the connection The driving motor fixed on the horizontal plate 73 works so that the output shaft of the driving motor can drive the guide wheel 71 to rotate through the rotating shaft rod 72. At this time, since the symmetrical guide wheel 71 is located on the upper surface of the horizontal plate at the lower end of the aluminum alloy guide rail 63, the rotation of the guide wheel 71 will move along the deformed aluminum alloy guide rail 63, and then can move by connecting the mounting box 74 and the drill bit 75 at the bottom end of the horizontal plate 73, so that the drill bit 75 can move linearly in an S shape above the S-shaped steel structure. When the drill bit 75 moves to the position of the steel structure corresponding to the need to drill a hole, the telescopic rod of the hydraulic cylinder 2 is controlled to retract, so that it drives the support top plate 3 and the drill bit 75 to move downward, thereby facilitating the drilling motor inside the mounting box 74 to drive the drill bit 75 to perform drilling operations.
