Description

Technical Field

[0002] Large-diameter, thick-wall spiral welded pipes, straight-seam welded pipes, and special-shaped steel pipes are widely used in domestic and foreign port construction piling construction, large-scale structural member main structure production, and steel structure factory main beam and column construction. During the construction process, the traditional construction method is mainly to gas-cut lifting holes or weld lifting ears at symmetrical positions on both sides of the pipe end on site. Since it is difficult to ensure the diameter of the gas-cut holes and the coaxiality tolerance, the welding lifting ear process is cumbersome and the shape and position tolerances are difficult to ensure, it brings great trouble to on-site use and there is a safety hazard of damage to the lifting equipment. The Chinese patent announcement number is: CN106112054B, which discloses "A steel pipe punching machine device and punching method". In the patent, the punching machine slideway is designed with one side being square and the other side being angular, which can effectively ensure that there is no radial movement during punching and improve the punching accuracy. The horizontally symmetrical punching machine ensures the coaxiality requirement of the punching. The steel pipe clamp ensures the stability of the steel pipe during punching. The present invention ensures the hole size and tolerance of the punching, ensures its coaxiality, and ensures the customer's requirements for safety, stability and accuracy during use. However, for large-diameter and thick-walled steel pipes, the structure of the steel pipe clamp is too large, and when the steel pipe is punched, a reverse force will be applied to the drill tool, causing the drill tool to deflect.

[0003] Existing drilling equipment for steel structures with fixed structures has problems such as how to stably drill large-diameter and thick-walled steel pipes due to structural design defects, and the drill cuttings from drilling from the inside to the outside are easily impacted onto the surface of the support platform, causing the steel pipe to deflect.

[0006] Preferably, there are two telescopic cylinders, and the inner wall drilling mechanism also includes a bent rod, which is fixedly installed at the output end of the telescopic cylinder. The end face position of the bent rod is fixedly connected with a toothed rod, and the position between the driving component and the drilling component is fixedly connected with a bracket, which pushes the steel pipe to the top of the support, and the inclined plate guides the steel pipe. Subsequently, the hydraulic cylinder drives the linear guide rail to approach the end face position of the steel pipe, and the guide slide table guides the linear guide rail to move. The screw rod is externally connected to a driving motor to rotate it, and the surface of the screw rod is threadedly connected to the inner side surface of one sliding cylinder, while the other sliding cylinder is driven to move by the linear guide rail. The two sliding cylinders move relative to each other and are close to the end face position of the steel pipe, so that the surface of the steel pipe is clamped.

[0008] Preferably, the driving assembly includes a shell, which is fixedly mounted on one end of the support rod away from the fixed body, and the side of the shell away from the support rod is fixedly connected to an internal gear cylinder. Steel pipes with large diameter and thick wall cannot be directly placed on the punching machine table for punching, and the punching structure will be subjected to the reverse force of the steel pipe during punching and cannot punch holes stably. In this device, the position of the steel pipe surface close to the end face is clamped by the oppositely arranged fixed table, and then two oppositely arranged transport carts gradually approach the steel pipe, and the telescopic cylinder on the left side drives the bending rod to approach the driving assembly.

[0013] Preferably, the drilling assembly also includes a motor, and the output end of the motor is fixedly connected to a drill rod, and the top end of the drill rod extends to the upper position of the frame. When the clamping assembly clamps the inner wall of the steel pipe, the threaded lifter drives the lifting block to move upward, and the drill rod is driven close to the inner wall of the steel pipe. The motor drives the drill rod to rotate rapidly, and the drill rod drills into the inner wall of the steel pipe. The drill rod always drills holes in the steel pipe from bottom to top, and the cylinder drives the inner concave tube to move upward, and the top of the rubber ring fits tightly against the inner wall of the steel pipe.

[0014] Preferably, the miscellaneous assembly comprises a cylinder, the bottom end of the cylinder is fixedly mounted on the bottom of the inner side of the frame, and the output end of the cylinder is fixedly connected to an inner concave cylinder.

[0015] Preferably, the miscellaneous component also includes a filter cartridge, which is fixedly mounted on the top of the fixed body, a hose is fixedly connected between the filter cartridge and the inner concave cylinder, and a fan is fixedly connected to the lower position of the filter cartridge surface. In the prior art, the steel pipe is lifted by welding lifting ears, and then holes are drilled from the outside to the inside. This method requires large-scale lifting equipment, and the heavy steel pipe is prone to cause the lifting ears to break and cause accidents. The connection of the tripod allows the length of the sliding cylinder to be lengthened, and the longer sliding cylinder makes the heavy and large-sized steel pipe more stable when being pushed. The drill rod moves from bottom to top to drill holes in the steel pipe. During the drilling process, some waste chips are splashed into the inside of the inner concave cylinder.

[0016] Preferably, a rubber ring is fixedly connected to the top of the inner concave cylinder, an air gun is fixedly connected to the bottom of the inner concave cylinder, and an output end of the air gun is inclined to the top of the drill rod.

[0017] The present invention provides a punching device for steel structure with a fixed structure. It has the following beneficial effects: 1. The punching equipment for steel structures with a fixed structure has multiple rollers in close contact with the surface of the steel pipe. The rolling of the rollers makes the friction resistance between the arc shell and the steel pipe smaller. The inner wall drilling mechanism punches holes on the top of the steel pipe from the inside out. With the drive of the lead screw and the linear guide rail, the steel pipe rolls on the top of the support, thereby punching multiple points on the surface of the steel pipe. The transport trolley changes its horizontal position as the steel pipe moves, and there is no need to lift the steel pipe for punching. This solves the problem of how to stably punch large-diameter and thick-walled steel pipes.

[0018] 2. The punching equipment for the steel structure with a fixed structure drives the assembly to engage with the tooth surface rod, and then the driving assembly drives the clamping assembly to expand and extend outward. The clamping assembly pressurizes the inner wall of the steel pipe, so that the driving assembly and the steel pipe are temporarily fixed. The drilling assembly drills a hole on the top of the steel pipe from bottom to top. Since the weight of the steel pipe is large, the drilling assembly uses the gravity of the steel pipe to drill from bottom to top. At this time, the drilling assembly does not need to rely on a large external pressure to complete the drilling, so that the large-diameter and thick-walled steel pipe is more stable and not easy to deflect when being punched.

[0019] 3. The punching equipment for steel structure with fixed structure has a C-shaped opening structure of the C-shaped block, which reduces the contact area between the steel pipe and the slider, avoids the local surface depression of the steel pipe so that the overall deflection of the shell is larger, and the contact between the large-diameter steel pipe and the alloy bar is more reliable. The positioning of the three sliders makes the shell firmly limited, and the clamping of the slider uses the weight of the steel pipe itself to press the drilling assembly. If the clamping method is not used, downward pressure needs to be applied to the transport trolley, and large torque will cause damage to the drilling assembly, which makes the device have a longer service life.

[0020] 4. In the drilling process of the punching equipment for steel structures with a fixed structure, the air gun sprays gas so that the waste chips on the surface of the drill rod are blown into the inner concave cylinder. The fan drives the air flow inside the inner concave cylinder through the hose to the filter cylinder. The filter cylinder deposits and collects the waste chips, and the gas is discharged through the fan. The connection of the rubber ring can prevent the waste chips from splashing out through the top of the inner concave cylinder. During the drilling process of the drill rod, the waste chips are not easily discharged from the top of the steel pipe, which solves the problem that the drill chips drilled from the inside to the outside are easily impacted to the surface of the support platform and cause the steel pipe to deflect.

[0021] 5. The punching equipment for steel structures with a fixed structure has an inner concave design of the inner concave cylinder which can effectively intercept waste chips. Some of the waste chips enter the filter cylinder through the hose, and some of the waste chips are wrapped around the surface of the drill pipe. During the drilling process of the drill pipe, the impact of the air gun promotes the discharge of waste chips and helps cool the drill pipe. When the drill pipe is about to complete the drilling, the air gun stops working. After the drill pipe moves down, the air gun flushes away the waste chips wrapped around the surface of the drill pipe, thereby preventing the waste chips from passing through the drill hole to the top of the support. The arc shell is not easy to adhere to waste chips when pushing the steel pipe, causing inaccurate drilling positioning. BRIEF DESCRIPTION OF THE DRAWINGS

The rolling of roller body 65 makes the friction resistance between arc shell 64 and the steel pipe smaller. The inner wall drilling mechanism 9 punches holes on the top of the steel pipe from the inside out. With the drive of screw rod 51 and linear guide rail 5, the steel pipe rolls on the top of support 1, thereby punching multiple points on the surface of the steel pipe. The transport trolley 7 changes its horizontal position with the movement of the steel pipe.

In the device, the surface of the steel pipe near the end face is clamped by the oppositely arranged fixed table 62, and then, two oppositely arranged transport trolleys 7 gradually approach the steel pipe, and the telescopic cylinder 8 on the left side drives the bending rod 95 to approach the driving component 93, and the driving component 93 engages with the tooth surface rod 96. Then, the driving component 93 drives the clamping component 94 to expand and extend outward, and the clamping component 94 pressurizes the inner wall of the steel pipe, so that the driving component 93 and the steel pipe are temporarily fixed, and the drilling component 97 drills a hole in the top of the steel pipe from bottom to top. Due to the heavy weight of the steel pipe, the drilling component 97 uses the gravity of the steel pipe to drill from bottom to top. At this time, the drilling component 97 does not need to rely on a large external pressure to complete the drilling, so that the large-diameter and thick-walled steel pipe is more stable and not easy to deflect when being punched.

The contact between the large-diameter steel pipe and the alloy bar 945 is more reliable. The positioning of the three sliders 941 makes the shell 931 firmly limited. The clamping of the slider 941 uses the weight of the steel pipe itself to press the drilling assembly 97. If the clamping method is not used, downward pressure needs to be applied to the transport trolley 7. The large torque will cause damage to the drilling assembly 97, which makes the device have a longer service life.

[0032] The miscellaneous component 98 includes a cylinder 981, the bottom end of which is fixedly mounted on the bottom of the inner side of the frame 971, and the output end of the cylinder 981 is fixedly connected to an inner concave cylinder 983. The miscellaneous component 98 also includes a filter cartridge 982, which is fixedly mounted on the top of the fixed body 91, and a hose is fixedly connected between the filter cartridge 982 and the inner concave cylinder 983, and a fan 986 is fixedly connected to the lower position of the surface of the filter cartridge 982, a rubber ring 984 is fixedly connected to the top of the inner concave cylinder 983, and an air gun 985 is fixedly connected to the bottom of the inner concave cylinder 983, and the output end of the air gun 985 is inclined to the top of the drill rod 975.

[0033] When in use, after the clamping assembly 94 clamps the inner wall of the steel pipe, the threaded lifter 972 drives the lifting block 973 to move upward, and the drill rod 975 is driven close to the inner wall of the steel pipe. The motor 974 drives the drill rod 975 to rotate rapidly, and the drill rod 975 drills into the inner wall of the steel pipe. The drill rod 975 always drills holes in the steel pipe from bottom to top. The cylinder 981 drives the inner concave cylinder 983 to move upward, and the top of the rubber ring 984 fits tightly with the inner wall of the steel pipe. During the drilling process, the air gun 985 sprays gas to make the drill rod The waste chips on the surface of 975 are blown into the inner concave cylinder 983. The fan 986 drives the air flow inside the inner concave cylinder 983 through the hose to the filter cylinder 982.

The connection of the rubber ring 984 can prevent the waste chips from splashing out through the top of the inner concave cylinder 983. During the drilling process of the drill rod 975, the waste chips are not easily discharged from the top of the steel pipe, which solves the problem that the drill chips drilled from the inside to the outside are easily impacted to the surface of the support platform and cause the steel pipe to deflect.

[0034] Fifth embodiment: Figure 4 , Fig.10 As shown, the top of the sliding cylinder 61 is fixedly connected to a fixed platform 62, the surface of the fixed platform 62 is fixedly connected to a tripod 63, the side of the fixed platform 62 away from the tripod 63 is fixedly connected to an arc shell 64, and the inner side of the arc shell 64 is rotatably connected to a roller body 65; the bottom end of the cylinder 981 is fixedly installed at the bottom of the inner side of the frame 971, and the output end of the cylinder 981 is fixedly connected to an inner concave cylinder 983, and the miscellaneous component 98 also includes a filter cartridge 982, and the filter cartridge 982 is fixedly installed on the top of the fixed body 91, and a hose is fixedly connected between the filter cartridge 982 and the inner concave cylinder 983, and a fan 986 is fixedly connected to the lower position of the surface of the filter cartridge 982, a rubber ring 984 is fixedly connected to the top of the inner concave cylinder 983, and an air gun 985 is fixedly connected to the bottom of the inner concave cylinder 983, and the output end of the air gun 985 is inclined to the top of the drill rod 975.

This method requires large-scale lifting equipment, and the heavy steel pipe is prone to cause the lifting lug to break and cause an accident. The connection of the tripod 63 allows the length of the slide cylinder 61 to be lengthened. The longer slide cylinder 61 makes the heavy and large-sized steel pipe more stable when being pushed. The drill rod 975 moves from bottom to top to drill holes in the steel pipe. During the drilling process of the drill rod 975, some waste chips are splashed into the interior of the inner concave cylinder 983. The inner concave design of the inner concave cylinder 983 can The waste chips are effectively intercepted, and some of the waste chips enter the filter cartridge 982 through the hose, and some of the waste chips are wrapped around the surface of the drill rod 975. During the drilling process of the drill rod 975, the impact of the air gun 985 promotes the discharge of waste chips and helps to cool the drill rod 975. When the drill rod 975 is about to complete the drilling, the air gun 985 stops working. After the drill rod 975 moves down, the air gun 985 flushes away the waste chips wrapped around the surface of the drill rod 975, thereby preventing the waste chips from passing through the drill hole to the top of the support 1. The arc shell 64 is not easy to adhere to the waste chips when pushing the steel pipe, causing the problem of inaccurate drilling positioning.
