[0014] Both sides of the outside of the drilling material rack are equipped with clamping electric cylinders, and the telescopic rods of the clamping electric cylinders are connected to clamping plates. The longitudinal section of the clamping plates is conical.

[0015] A triangular plate is installed below the clamping plate and is mounted on the guide frame.

The positive and negative plates are electrically connected to the control system.

[0016] The buffer plate is provided with Seebeck wire, and the temperature control channel is provided with low temperature wire. Both Seebeck wire and low temperature wire are composed of metal wire and two kinds of semiconductor wires of different materials.

[0019] A temperature sensor is installed on the heating plate, and the temperature sensor is used to detect the temperature of the angle steel at the drilling location.

[0020] The guide frame is equipped with a control box, and the control system is located inside the control box.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. By coordinating the top and bottom spray frames, the drill bit's two sides are cooled simultaneously, extending its service life. The control system gradually reduces the coil current until it is de-energized. The magnetic field strength generated by the coil gradually decreases, the magnetic moment of the magnetic material decreases during demagnetization, the magnetic entropy increases, and the temperature of the magnetic material gradually decreases. At this time, the coolant system delivers coolant to the temperature-controlled flow channel and the bottom spray frame through pipes. The magnetic material cools the coolant in the temperature-controlled flow channel. The cooled coolant is then delivered to the top spray nozzle through the temperature-controlled flow channel and pipes. The top spray nozzle sprays the angle steel at the drilling location, lubricating and cooling the drill bit while washing away the generated debris. The bottom spray frame cools the drill bit passing through the angle steel, thus lowering the overall temperature of the drill bit and improving its service life.

[0023] 2. By preheating and intelligent precise temperature control, the pressure required for drilling is reduced, improving drilling efficiency. The positive and negative plates on the right are connected to the positive and negative terminals of the power supply, respectively. Current flows through the area of ​​the angle steel to be drilled, causing it to heat up and deform. This not only reduces the drilling pressure but also reduces drill bit wear and extends its lifespan. The control system connects the coil to the circuit and increases the current flowing through it. The magnetic field generated by the coil causes the magnetic moment of the magnetic material to increase in an orderly manner, leading to a decrease in magnetic entropy. This causes the magnetic material to heat up, and the heating plate reheats the area of ​​the angle steel to be drilled through this magnetic material. Since the area has already been heated by the positive and negative plates, the heating plate saves heating time and improves heating efficiency when reheating this area.

[0024] 3. Coolant and debris are separated and the separated coolant is recycled to improve coolant utilization. The coolant impacts downwards onto a buffer plate. The downward impact force of the coolant is greater than the spring force of the buffer spring, causing the buffer plate to compress the spring and move downwards. After being buffered by the buffer plate, the coolant diffuses outwards through the outer wall of the buffer plate. After passing through multiple filter screens, the coolant re-enters the coolant system from the bottom of the collection tank and through pipes, achieving coolant filtration and reuse, thus improving coolant utilization.

[0025] 4. Heat recovery and treatment to reduce the energy consumption of the drilling equipment. The control system connects the two types of semiconductor wires on the Seebeck wire and the two types of semiconductor wires on the cryogenic wire to the circuit. At this time, the coolant gradually increases in temperature after exchanging heat with the drill bit and angle steel. The increased temperature of the coolant is buffered by the buffer plate, which expands the range of the coolant. The temperature of the Seebeck wire in the buffer plate is higher than that of the cryogenic wire, that is, the temperature of the hot end is higher than that of the cold end. The hot end and the cold end generate current through the Seebeck effect, which is transmitted to the control system through the wire. The control system processes the current and then uses it to reduce the energy consumption of the drilling equipment. Attached Figure Description

[0037] Example: Figures 1-9As shown, this invention provides a technical solution for a drilling device for angle steel towers with variable cross-section adaptive clamping, including a coolant system (not shown in the figure), a transfer mechanism (not shown in the figure), a control system, and a guide frame 11.

The transplanting mechanism, guide frame 11, drilling frame 112, shearing frame 113 and unloading frame 114 are all set on the ground. Several conical wheels 111 are electric rollers. The conical wheels 111 have built-in encoders. A control box 1 is set on the guide frame 11. The control system is set in the control box 1. The shearing electric cylinder 4 is installed on the shearing frame 113. The shearing plate 41 is set on the telescopic rod of the shearing electric cylinder 4. A shearing blade is set on the lower side of the shearing plate 41. The two sides of the conical wheel 111 are conical, which can adapt to angle steel with different cross sections, realize the conveying of angle steel with different cross sections, and cooperate with the clamping plate 241 to achieve adaptive clamping.

[0038] The top spray frame 21 is located in the middle of the drilling material rack 112. A lifting cylinder 211 is connected to the upper side of the top spray frame 21, and the lifting cylinder 211 is installed on the drilling material rack 112. Several telescopic shafts are provided on the lower side of the top spray frame 21. The telescopic shafts are telescopic structures, and two sets of heating plates 212 are connected to them. The two sets of heating plates 212 are inclined and symmetrically arranged. Return springs are sleeved on the telescopic shafts, and the two ends of the return springs are connected to the heating plates 212 and the top spray frame 21, respectively. A coil 213 is embedded on the upper side of the heating plate 212. A temperature control channel is provided in the middle of the heating plate 212. The lower side of the heating plate 212 is made of magnetic material. Several upper spray nozzles are provided at the bottom of the heating plate 212. The two ends of the coil 213 are electrically connected to the control system. The magnetic material is located in the magnetic field of the coil 213. The outlet of the temperature control channel is connected to several spray nozzles through a pipe. A temperature sensor is provided in the temperature control channel. A temperature sensor is installed on the heating plate 212. The temperature sensor is used to detect the temperature of the angle steel at the drilling location.

[0039] Multiple sets of bottom spray racks 22 are provided. The longitudinal section of the multiple sets of bottom spray racks 22 is triangular. The bottom spray racks 22 are hollow inside. The bottom spray racks 22 are provided with lower spray nozzles. The upper spray nozzles and lower spray nozzles are directly opposite the positions where the angle steel needs to be drilled. The inlet of the temperature control channel and the bottom spray racks 22 are connected to the coolant system through pipes. One-way valves are provided in both the upper spray nozzles and lower spray nozzles.

[0040] The top and bottom of the collection tank 3 are respectively equipped with a flow collector 301 and a collection cylinder 302. The bottom of the collection tank 3 outside the collection cylinder 302 is connected to the coolant system through a pipe. The longitudinal section of the flow collector 301 is "V" shaped. A manifold is provided on the lower side of the flow collector 301. A liquid level sensor and a solenoid valve are respectively installed in the flow collector 301 and the manifold. The liquid level sensor and the solenoid valve are electrically connected to the control system. A buffer plate 31 is slidably installed on the top of the collection cylinder 302. The longitudinal section of the buffer plate 31 is conical. The buffer plate 31 is located below the manifold. A buffer spring 32 is connected between the buffer plate 31 and the collection cylinder 302. The two ends of the buffer spring 32 are electrically connected to the control system.

[0041] When the coolant system detects that the coolant inflow rate is lower than the set value, the control system continuously energizes and de-energizes the buffer spring 32. When the buffer spring 32 is energized, it gradually contracts, pulling the buffer plate 31 downward. When the buffer spring 32 is de-energized, it pushes the buffer plate 31 upward through its own elasticity, so that the buffer plate 31 vibrates continuously up and down. The buffer plate 31 drives the uppermost filter screen 33 to vibrate, and the uppermost filter screen 33 drives the lower filter screen 33 to vibrate synchronously through the reinforcing ribs, so that the impurities on the filter screen 33 can quickly pass through the collection tank into the collection cylinder 302, thereby increasing the pass rate of coolant on the filter screen 33 and increasing the flow rate of coolant entering the coolant system.

[0042] The control system flexibly adjusts the frequency of energizing and de-energizing the buffer spring 32 based on the flow data detected by the coolant system. The smaller the detected flow data, the greater the frequency of energizing and de-energizing the buffer spring 32, the more violently the buffer spring 32 vibrates, the more violently the buffer plate 31 vibrates, and the more violently the buffer plate 31 drives the filter screen 33 to vibrate, resulting in a better cleaning effect on the filter screen 33.

[0043] A filter screen 33 is connected between the inner wall of the collection cylinder 302 and the collection box 3. Multiple filter screens 33 are arranged sequentially from top to bottom. A collection groove is opened between two adjacent filter screens 33 in the collection cylinder 302. The collection groove is connected to the inside of the collection cylinder 302. A detachable chip removal plate is provided at the bottom of the collection cylinder 302. A reinforcing rib is connected between two adjacent filter screens 33. Both the filter screen 33 and the reinforcing rib are elastic. The filter screen 33 is inclined. The filtration effect of the lower filter screen 33 is better than that of the upper filter screen 33. The lower side of the buffer plate 31 is connected to the uppermost filter screen 33.

[0044] Two sets of guide rails are provided on the drilling material rack 112, and slide plates 23 are slidably mounted on the two sets of guide rails. Drilling cylinders 231 are connected to the slide plates 23, and drilling cylinders 231 are mounted on the drilling material rack 112. The spindle motor 2 is mounted on the slide plates 23. The drilling cylinders 231, guide rails, slide plates 23, spindle motor 2, and drill bits form a drilling unit. Multiple drilling units are provided on the drilling material rack 112. Drilling material rack 112 is equipped with drill bits on both sides of its exterior. There is a clamping electric cylinder 24, and the telescopic rod of the clamping electric cylinder 24 is connected to a clamping plate 241. The longitudinal section of the clamping plate 241 is conical. A triangular plate 242 is installed below the clamping plate 241 and is mounted on the guide frame 11. Positive electrode plate 243 and negative electrode plate 244 are respectively set at the positions where the angle steel needs to be drilled, and the positive electrode plate 243 and negative electrode plate 244 are electrically connected to the control system.

[0045] A Seebeck wire 311 is provided on the buffer plate 31, and a low-temperature wire 312 is provided in the temperature control channel. Both the Seebeck wire 311 and the low-temperature wire 312 are composed of metal wire and two kinds of semiconductor wires of different materials. One end of each of the two kinds of semiconductor wires is connected to the metal wire. The two kinds of semiconductor wires on the Seebeck wire 311 and the two kinds of semiconductor wires on the low-temperature wire 312 are connected by wires. One of the wires is connected to the control system. The Seebeck wire 311 is the hot end of the Seebeck effect, and the low-temperature wire 312 is the cold end of the Seebeck effect.

[0046] During the drilling process, the control system connects the two semiconductor wires on Seebeck wire 311 and the two semiconductor wires on cryogenic wire 312 to the circuit. At this time, the coolant gradually increases in temperature after exchanging heat with the drill bit and angle steel. The increased temperature of the coolant is buffered by buffer plate 31, which expands the range of the coolant. The temperature of Seebeck wire 311 in buffer plate 31 is higher than that of cryogenic wire 312, that is, the temperature of the hot end is higher than that of the cold end. The hot end and the cold end generate current through Seebeck effect and transmit it to the control system through wires. The control system processes the current and then uses it.

[0047] Working principle: Pressing the start button on control box 1 starts the device. The angle steel is placed on several conical wheels 111, which transport the angle steel forward and move the position where the angle steel needs to be drilled to be directly below the right-side clamping electric cylinder 24. At this time, the position where the angle steel needs to be drilled is in contact with the negative electrode plate 244 on the triangular plate 242. The right-side clamping electric cylinder 24 drives the right-side clamping plate 241 and the right-side positive electrode plate 243 to move downward, so that the position on the angle steel that needs to be drilled is in contact with the right-side positive electrode plate 243. Therefore, the angle steel that needs to be drilled contacts the positive plate 243 and the negative plate 244 on the right side, respectively. According to the data of the encoder in the clamping cylinder 24 and the conical wheel 111, the control system connects the positive plate 243 and the negative plate 244 on the right side to the positive and negative terminals of the power supply, respectively. Current flows through the angle steel that needs to be drilled, so that the angle steel that needs to be drilled heats up and deforms. This not only reduces the pressure required for drilling, but also reduces the wear of the drill bit and increases the service life of the drill bit.

[0048] When the positive electrode plate 243 and the negative electrode plate 244 on the right are energized for a set time, the control system de-energizes the positive electrode plate 243 and the negative electrode plate 244 on the right, and drives the clamping plate 241 and the positive electrode plate 243 on the right to move upward through the clamping cylinder 24 on the right. Then, the conical wheel 111 continues to drive the heated angle steel to move into the drilling material rack 112, so that the position of the angle steel to be drilled is directly opposite the drill bit.

[0049] When the angle steel needs to be drilled at the location directly opposite the drill bit, the drilling location is outside the bottom spray frame 22. The encoder inside the conical wheel 111 feeds data back to the control system. The control system then moves the top spray frame 21 downward via the lifting cylinder 211. The top spray frame 21 moves the two sets of heating plates 212 downward, pressing them against the drilling location on the angle steel. Simultaneously, the return spring is compressed. The control system connects the two ends of the coil 213 to the circuit and increases the current flowing through the coil 213. The magnetic field generated by the coil 213 causes the magnetic material to... The orderly increase of the magnetic moment leads to a decrease in magnetic entropy, causing the magnetic material to heat up. The heating plate 212 reheats the angle steel at the drilling location using the magnetic material, ensuring that the drilling location reaches the set temperature. The temperature sensor on the heating plate 212 feeds back the angle steel's temperature data to the control system in real time to achieve precise temperature control. Since the drilling location has already been heated by the positive plate 243 and negative plate 244, the heating plate 212 can save heating time and improve heating efficiency when heating the drilling location.

[0050] When the angle steel needs to be drilled at the set temperature, the control system drives the top spray frame 21 to move upward through the lifting electric cylinder 211. The top spray frame 21 then drives the two sets of heating plates 212 to move upward, so that the drill bit can drill holes in the angle steel.

[0051] When the heating plate 212 moves upward to the set position, the encoder in the lifting cylinder 211 feeds back the data to the control system. The control system drives the sliding plate 23 to move towards the angle steel through the drilling cylinder 231. The sliding plate 23 drives the spindle motor 2 and the drill bit to move synchronously, so that the spindle motor 2 drives the drill bit to drill holes in the angle steel.

[0052] During the drilling process of the angle steel, the control system gradually reduces the current of coil 213 until it is de-energized. The magnetic field strength generated by coil 213 gradually decreases, the magnetic moment of the magnetic material decreases when it is demagnetized, the magnetic entropy increases, and the temperature of the magnetic material gradually decreases. At this time, the coolant system delivers coolant to the temperature control channel and the bottom spray frame 22 through pipes. The magnetic material cools the coolant in the temperature control channel. The cooled coolant is delivered to the upper spray nozzle through the temperature control channel and pipes. It is sprayed on the position of the angle steel being drilled through the upper spray nozzle, which lubricates and cools the drill bit while washing away the generated debris downwards. The bottom spray frame 22 cools the drill bit that passes through the angle steel so that the overall temperature of the drill bit decreases and the service life of the drill bit is improved.

[0053] After the coolant is sprayed onto the angle steel, the coolant and debris fall downwards into the manifold 301. A level sensor inside the manifold 301 detects the coolant level. When the coolant flow rate in the manifold 301 reaches a set value, the control system opens the solenoid valve inside the manifold based on the data from the level sensor. At this time, the coolant is delivered downwards through the manifold, impacting the buffer plate 31. The downward impact force of the coolant is greater than the elastic force of the buffer spring 32, causing the buffer plate 31 to compress the buffer spring. Spring 32 moves downward, buffer plate 31 buffers the downward coolant, and the coolant diffuses outward through the outer wall of buffer plate 31. After passing through multiple filter screens 33, the coolant re-enters the coolant system from the bottom of collection tank 3 and pipe, thus achieving the filtration of coolant and reuse of coolant. Meanwhile, debris is filtered by multiple filter screens 33 and moves along the inclined filter screens 33 to the collection tank. The debris enters the collection cylinder 302 through the collection tank. The operator can disassemble the chip removal plate to clean the debris in the collection cylinder 302.

[0054] When the coolant in the manifold 301 does not reach the set value, the spring force of the buffer spring 32 is less than the downward impact force of the coolant, and the buffer spring 32 is released. The buffer spring 32 pushes the buffer plate 31 to move upward. Through the interaction of the impact force of the coolant and the spring force of the buffer spring 32, the buffer plate 31 moves up and down continuously, thereby causing the buffer plate 31 to vibrate. The buffer plate 31 drives the uppermost filter screen 33 to vibrate synchronously, and through the reinforcing ribs, it drives multiple filter screens 33 below to follow the vibration, so that the debris on the filter screen 33 can enter the collection tank more quickly. In addition, the vibrating filter screen 33 makes it easier for the coolant to pass through, avoiding the clogging of the filter screen 33 and ensuring the filtration effect of the filter screen 33.

[0055] After drilling is completed, the drilling cylinder 231 moves the sliding plate 23 away from the angle steel. The sliding plate 23 drives the spindle motor 2 and the drill bit to move away from the angle steel synchronously. The coolant supply is paused through the coolant system to stop the coolant spraying. The conical wheel 111 moves the angle steel to be cut to the position directly below the left clamping cylinder 24. At this time, the angle steel to be cut is located on the left negative plate 244. The left clamping cylinder 24 moves the left clamping plate 241 downward. The left clamping plate 241 moves the left positive plate 243 downward so that the angle steel to be cut contacts the left positive plate 243 and the left negative plate 244 respectively. The control system connects the left positive plate 243 and the left negative plate 244 to the circuit, so that current flows through the angle steel to be cut, causing deformation and heat generation at the angle steel to be cut, reducing the downward shearing force of the shearing plate 41.

[0056] When the positive plate 243 and the negative plate 244 on the left are energized for a set time, the control system de-energizes the positive plate 243 and the negative plate 244 on the left and moves the clamping plate 241 and the positive plate 243 on the left away from the angle steel through the clamping cylinder 24 on the left. At this time, the conical wheel 111 moves the angle steel to the position where it needs to be cut to the position directly below the shearing plate 41. The shearing cylinder 4 moves the shearing plate 41 downward and the shearing plate 41 cuts the angle steel with the shearing blade, making the angle steel segmented. After that, the shearing cylinder 4 moves the shearing plate 41 upward back to its original position.

[0057] After the shearing plate 41 segments the angle steel, the control system continues to drive the segmented angle steel forward through the conical wheel 111, so that the segmented angle steel moves to one side of the unloading rack 114. At this time, the transfer mechanism moves the segmented angle steel onto the unloading rack 114 to realize the unloading and storage of the segmented angle steel.
