Description

Technical Field

[0001] This invention belongs to the field of cable tray processing technology, specifically a high-efficiency drilling device for cable tray processing. Background Technology

[0002] The holes in cable trays can be used for natural ventilation or ventilation equipment to maintain normal ventilation and heat dissipation in the cable trays and to ensure the safety of cable routing; drilling is required during the production and processing of cable trays;

[0003] However, when drilling cable trays, the common method is to manually limit the sides and then use a drilling machine to open holes in the surface. Because cable trays are long and require a large number of holes, which are often evenly distributed, many limiters and loosening replacements are needed when drilling one or more cable trays. This greatly reduces drilling efficiency. At the same time, when drilling cable trays, the drill bit is in contact with the cable tray surface. Under the influence of different forces, the drill bit may be overloaded, which can cause drilling damage and even damage to the motor core. This greatly increases the maintenance efficiency and cost of the drilling equipment.

[0004] In view of this, a high-efficiency drilling device for cable tray processing is proposed to overcome the above problems. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] Given the following technical problems in the existing technology: When drilling cable trays, the common method is to manually limit the sides of the trays and then use a drilling machine to open holes in the surface. Due to the long distance of the cable trays and the large number of holes required on the surface of the cable trays, which are mostly evenly distributed, it is necessary to limit and loosen the trays many times when drilling one or more cable trays. This greatly reduces the drilling efficiency. At the same time, when drilling cable trays, the drill bit is in contact with the surface of the cable tray. Under the influence of different forces, the drill bit may be overloaded, which can cause drilling damage. In severe cases, it may even damage the motor core. This greatly increases the maintenance efficiency and cost of the drilling equipment.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a high-efficiency drilling device for cable tray processing, comprising a support base, a positioning plate and a drilling machine;

[0008] The positioning plate has parallel-distributed limiting plates and flexible plates arranged on its inner edge. A hinge frame is arranged between the limiting plates and the flexible plates. A channel is milled in the middle of the positioning plate. A threaded rod is arranged in the channel. One end of the threaded rod extends out of the positioning plate and abuts against the surface of the limiting plate.

[0009] The positioning plate is milled with a third channel, which communicates with the first channel, and a rack is telescopically connected in the third channel;

[0010] The drilling machine is equipped with a motor, drill rod one, drill rod two, and obstruction pad one. The output end of the motor is connected to drill rod two. One end of drill rod one extends out of the drilling machine and is connected to a drill bit. The linkage between drill rod two and drill rod one is hinged.

[0011] The surface of the push cylinder has a channel four reserved. A positioning post is fixedly connected to the surface of the drill rod one near the channel four. The positioning post is located inside the channel four. The distance between the upper and lower walls of the inner edge of the channel four is greater than the diameter of the positioning post. The push cylinder and the drill rod one rotate synchronously. The push cylinder moves in extension and retraction on the drill rod one.

[0013] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, an internal threaded sleeve is movably configured in the first channel, and the internal threaded sleeve and the threaded rod are driven by a thread. A directional cylinder is fixedly connected to the outer surface of the positioning plate. The end of the threaded rod that does not extend into the positioning plate is located in the directional cylinder. The inside of the directional cylinder is configured with a groove that connects with the guide block at the tail end of the threaded rod. A second channel is reserved on the inner edge surface of the positioning plate. A guide rod is telescopically moved in the second channel, and the end of the guide rod that extends out of the second channel is fixedly connected to the surface of the limiting plate.

[0014] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, the rack engages with an internal threaded sleeve for transmission, the top end of the rack is connected to a linkage plate, and the end of the linkage plate away from the rack is connected to the outer periphery of the drilling machine.

[0015] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, the pushing assembly includes an elastic element, a guide seat, and a linkage cylinder. The elastic element surrounds the outer periphery of the drill rod, and the guide seat is located on the outer periphery of the end of the drill rod near the drill bit. The inner edge of the guide seat is fixedly connected to the outer peripheral surface of the drill rod.

[0016] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, the end of drill rod one facing drill rod two is located inside the end of drill rod two facing drill rod one. A docking seat, a second obstruction pad, and a hollow cylinder are arranged outside the end of drill rod one inside drill rod two. The docking seat is fixedly connected to drill rod one. The hollow cylinder is located on the outer periphery of drill rod one, and the inner edge of the hollow cylinder does not directly contact the outer side of drill rod one. The hollow cylinder moves in a telescopic motion along the inner edge of drill rod two. The hollow cylinder rotates synchronously with drill rod two. The second obstruction pad is located between the hollow cylinder and the docking seat. A guide cylinder is arranged along the inner edge of the hollow cylinder, and the inner edge of the guide cylinder is in contact with the outer periphery of drill rod one.

[0017] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, the first linkage cylinder is disposed on the outer periphery of the second drill rod. The second linkage cylinder and the third linkage cylinder are disposed on the outer side of the first drill rod near the guide seat and the elastic element. The end of the second linkage cylinder away from the third linkage cylinder is connected to the elastic element. The surface of the third linkage cylinder is provided with a thread.

[0018] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, the inner edge of the first linkage cylinder near the third linkage cylinder is provided with a second thread, and a rotating seat is movably arranged on the side of the first linkage cylinder near the second thread. The inner surface of the rotating seat is provided with a third thread. When the third linkage cylinder is in different positions, it is in a threaded linkage relationship with the second thread and the rotating seat respectively. The second linkage cylinder is located on the outer periphery of the first drill rod, and the connection relationship between the second linkage cylinder and the first drill rod is telescopic. The second linkage cylinder and the first drill rod rotate synchronously.

[0019] As a preferred technical solution for a high-efficiency drilling device for cable tray processing, the second linkage cylinder is milled with a curved slope and a limiting block at one end near the third linkage cylinder, the third linkage cylinder is milled with a curved slope and a guide channel at one end near the second linkage cylinder, the limiting block is located on the curved slope, wherein the slope distance of the curved slope is greater than the slope distance of the curved slope, and the bottom end of the limiting block is located beyond the lowest position of the curved slope. The guide channel is used for the movement of the limiting block.

[0020] The beneficial effects of this invention are:

[0021] 1. When the drilling machine descends to drill holes in the cable tray, the rack descends with the drilling machine and inserts into channel three. Under the action of meshing transmission, the internal threaded sleeve rotates, and under the action of thread linkage, the threaded rod extends and retracts. Under the restriction of the guide rod and channel two, the two limiting plates can move towards the cable tray synchronously. When the flexible plate is in contact with the cable tray, the drill bit contacts the surface of the cable tray, which can prevent the cable tray from moving during drilling, thus preventing low drilling efficiency. At the same time, when the drilling machine rises and drills the same cable tray surface in a different position, the internal threaded sleeve reverses, and the limitation of the flexible plate on the cable tray is reduced. This can ensure that the conveying roller can transport the cable tray backward normally, so that the device is always in a high-efficiency state when drilling cable trays and improves the drilling accuracy of the device.

[0022] 2. This device uses a hinged frame and a flexible plate to allow the flexible plate to move elastically after contacting the cable tray surface. This allows for two purposes: firstly, it can limit the position of cable trays of different sizes; secondly, it can accommodate different distances from when the drill bit just touches the cable tray to when it drills into the cable tray.

[0023] 3. This device enables drill rod 2 to operate normally in conjunction with drill rod 1 through the resistance force between the first resistance pad, the second resistance pad, and the hollow cylinder. At the same time, when the load on the drill bit exceeds the limit, the resistance force between the first resistance pad, the second resistance pad, and the hollow cylinder can be gradually reduced to zero. At this time, it can ensure that drill rod 2 is normally driven by the motor, while drill rod 1 stops rotating, thereby protecting drill rod 1, drill rod 2, and the motor.

[0024] 4. Through the coordinated action of linkage cylinder three, linkage cylinder two, elastic element and push cylinder, this device can change the resistance force between obstruction pad one, obstruction pad two and hollow cylinder, and can operate within the normal load range of the drill bit. At the same time, under the action of curve slope one, curve slope two, limit block and guide channel, when the load force of the drill bit changes, the resistance force between obstruction pad one, obstruction pad two and hollow cylinder also changes. Firstly, it improves the efficiency of drilling bridges, and secondly, it can prevent the resistance force between obstruction pad one, obstruction pad two and hollow cylinder from always being at the maximum limit, so that obstruction pad two and hollow cylinder can be used for a longer period of time.

[0043] Example 1

[0044] Reference Figures 1 to 4 This is the first embodiment of the present invention, which provides a high-efficiency drilling device for cable tray processing, including a support base 100, a positioning plate 200 and a drilling machine 300;

[0045] The positioning plate 200 is symmetrically fixed to the surface of the bearing base 100. The surface of the bearing base 100 is provided with a movably connected conveying roller 101. A cylinder 103 is provided on the inner edge of the top end of the conveying roller 101. The top end of the drilling machine 300 is connected to the output end of the cylinder 103. An X-axis control mechanism 104 that can change the position of the bearing frame 102 is provided on the bearing base 100. A Z-axis control mechanism 105 that can change the position of the cylinder 103 is provided on the bearing frame 102.

[0046] refer to Figure 5 Each of the two positioning plates 200 has a limiting plate 201 and a flexible plate 202 along its inner edge. A hinge frame 203 is provided between the limiting plate 201 and the flexible plate 202. The end of the hinge frame 203 near the limiting plate 201 is telescopic. The configuration of the hinge frame 203 allows the flexible plate 202 to elastically telescopically move, thereby better limiting the cable tray. A channel 204 is milled in the middle of the positioning plate 200. A threaded rod 205 is provided in the channel 204. One end of the threaded rod 205 extends out of the positioning plate 200 and abuts against the surface of the limiting plate 201. An internal threaded sleeve 206 is movably arranged in the channel 204, and the internal threaded sleeve 206 and the threaded rod 205 are connected. For threaded transmission, a guide cylinder 207 is fixedly connected to the outer surface of the positioning plate 200. The end of the threaded rod 205 that does not extend into the positioning plate 200 is located in the guide cylinder 207. The guide cylinder 207 has a groove inside that connects with the guide block at the tail end of the threaded rod 205, so that the threaded rod 205 can only move linearly and cannot rotate, thus protecting the tail end of the threaded rod 205. A second channel 209 is reserved on the inner edge surface of the positioning plate 200. A guide rod 208 moves telescopically in the second channel 209. One end of the guide rod 208 that extends out of the second channel 209 is fixedly connected to the surface of the limiting plate 201. The stability of the limiting plate 201 when it moves is improved by the guide rod 208 and the second channel 209.

[0047] refer to Figure 2 and 4 The positioning plate 200 is milled with a channel 3 210, which is connected to the channel 1 204. A rack 211 is telescopically connected in the channel 3 210. The outer periphery of the internal threaded sleeve 206 is provided with teeth. The rack 211 and the internal threaded sleeve 206 mesh and drive each other. The top end of the rack 211 is connected to a linkage plate 212. The end of the linkage plate 212 away from the rack 211 is connected to the outer periphery of the drilling machine 300, so that when the drilling machine 300 moves telescopically, the rack 211 and the linkage plate 212 can move telescopically synchronously.

[0048] When drilling holes in the cable tray, the X-axis control mechanism 104 and the Z-axis control mechanism 105 first ensure that the drilling machine 300 is aligned with the location where the cable tray needs to be drilled. Then, the cylinder 103 lowers the drilling machine 300 to drill the cable tray. Simultaneously, as the drilling machine 300 descends, the rack 211 inserts into the channel 210. At this time, the internal threaded sleeve 206 rotates, and under the influence of the threaded linkage, the threaded rod 205 can extend and retract. Through the guide rod 208 and the channel 209, the two limiting plates 201 can move closer to the cable tray. With the cooperation of the hinge frame 203 and the flexible plate 202, cable trays of different sizes can be limited for drilling. After drilling is completed, the drilling machine 300 rises. At this time, the internal threaded sleeve 206 reverses, and the limiting force of the flexible plate 202 on the cable tray decreases. This ensures that the cable tray can be transported backward and its position changed for convenient subsequent processing.

[0049] Example 2

[0050] Reference Figures 6 to 7 This is the second embodiment of the present invention. This embodiment differs from the previous embodiment in that: the drilling machine 300 is equipped with a motor 301, a first drill rod 303, a second drill rod 304, and a first obstruction pad 305. The output end of the motor 301 is connected to the second drill rod 304. One end of the first drill rod 303 extending out of the drilling machine 300 is connected to a drill bit 302, which is used to drill holes in cable trays. The second drill rod 304 and the first drill rod 303 are hinged. The first obstruction pad 305 is located outside the first drill rod 303. A position-adjustable pusher 306 is also provided outside the first drill rod 303. When the pusher 306 changes position on the first drill rod 303, it only extends and retracts. The pusher 306 rotates synchronously with the first drill rod 303. A pusher assembly is also provided outside the first drill rod 303, which is used to change the linkage resistance between the first obstruction pad 305 and the second drill rod 304 and the first drill rod 303.

[0051] The pushing assembly presses the first obstruction pad 305 against the surface of the second drill rod 304, making the two fit more closely. The pushing cylinder 306 moves together with the first drill rod 303. Under the pressure of the first obstruction pad 305, the movement resistance of the second drill rod 304 and the first drill rod 303 increases. At this time, the first drill rod 303 can gradually move synchronously with the second drill rod 304, eventually reaching the same speed. When the drill bit 302 exceeds the load limit or slips when drilling a cable tray, the force restricting the working end of the drill bit 302 exceeds the obstruction force of the first obstruction pad 305. In this case, the second drill rod 304 can work normally, while the first drill rod 303 is stopped or running slowly. This can prevent the drill bit 302 and the first drill rod 303 from breaking due to excessive working load.

[0052] refer to Figure 7 The pushing assembly includes an elastic element 307, a guide seat 308, and a linkage cylinder 312. The elastic element 307 surrounds the outer periphery of the drill rod 303. The guide seat 308 is located on the outer periphery of the drill rod 303 near the drill bit 302, and the inner edge of the guide seat 308 is fixedly connected to the outer periphery of the drill rod 303. In this solution, the elastic element 307 is always under force after the whole assembly, only the magnitude of the force is different. The model of the elastic element 307 is selected according to the size of the hole and the thickness of the cable tray.

[0053] refer to Figure 7 The end of drill rod 303 facing drill rod 304 is located inside the end of drill rod 304 facing drill rod 303. The end of drill rod 303 inside drill rod 304 is equipped with a docking seat 309, a second obstruction pad 310 and a hollow cylinder 311. The docking seat 309 is fixedly connected to drill rod 303. The hollow cylinder 311 is located on the outer periphery of drill rod 303, and the inner edge of the hollow cylinder 311 does not directly contact the outer side of drill rod 303. The hollow cylinder 311 moves in a telescopic motion along the inner edge of drill rod 304. The hollow cylinder 311 rotates synchronously with drill rod 304. The second obstruction pad 310 is located between the hollow cylinder 311 and the docking seat 309. With the help of the first obstruction pad 305 and the second obstruction pad 310, the hollow cylinder 311 can first move synchronously with drill rod 303, and finally the drill rod 303 and drill rod 304 can move synchronously.

[0054] When the drill rod 303 exceeds the limit of the drilling load on the cable tray, the resistance of the first obstruction pad 305 and the second obstruction pad 310 to the hollow cylinder 311 decreases or even disappears. The cost of the first obstruction pad 305 and the second obstruction pad 310 is lower than that of the drill rod 303. Moreover, the drill rod 303 can continue to be used after simply replacing the first obstruction pad 305 and the second obstruction pad 310. However, if the drill rod 303 breaks, not only does it need to be replaced, but the broken debris also needs to be carefully cleaned. The inner edge of the hollow cylinder 311 is equipped with a guide cylinder 321. The inner edge of the guide cylinder 321 fits against the outer periphery of the drill rod 303. The function of the guide cylinder 321 is to ensure that the drill rod 303 does not rotate when the first obstruction pad 305 and the second obstruction pad 310 do not provide resistance to the hollow cylinder 311.

[0055] refer to Figure 7 and 11 The surface of the push cylinder 306 has a channel 316. A positioning post 315 is fixedly connected to the surface of the drill rod 303 near the channel 316. The positioning post 315 is located inside the channel 316. The distance between the upper and lower walls of the inner edge of the channel 316 is greater than the diameter of the positioning post 315, so that the push cylinder 306 can rotate synchronously with the drill rod 303, and the push cylinder 306 can also perform telescopic movement on the drill rod 303.

[0056] refer to Figure 7 Linkage cylinder 312 is disposed on the outer periphery of drill rod 304. Linkage cylinder 313 and linkage cylinder 314 are disposed on the outer side of drill rod 303 near guide seat 308 and elastic element 307. Linkage cylinder 313 is connected to elastic element 307 at the end away from linkage cylinder 314. Thread 1 is disposed on the surface of linkage cylinder 314. Thread 2 is disposed on the inner edge of linkage cylinder 312 near linkage cylinder 314. Rotating seat 322 is movably disposed on the side of linkage cylinder 312 near thread 2. Thread 3 is disposed on the inner edge surface of rotating seat 322. When linkage cylinder 314 is in different positions, it is threadedly linked with thread 2 and rotating seat 322 respectively. Linkage cylinder 313 is located on the outer periphery of drill rod 303, and the connection between linkage cylinder 313 and drill rod 303 is telescopic. Linkage cylinder 313 and drill rod 303 rotate synchronously.

[0057] When the load on the drill bit 302 increases during drilling of the cable tray, the drilling speed of drill rod 303 gradually decreases, and the rotational speed of drill rod 304 exceeds that of drill rod 303. At this time, the threaded linkage of the linkage cylinder 314 and the inner thread of the linkage cylinder 312 causes the linkage cylinder 313 to move, thereby pressing the elastic element 307. The elastic element 307 can push the push cylinder 306. At this time, the obstruction pad 305, the obstruction pad 310, and the hollow cylinder 311 fit more closely, thereby increasing the linkage effect. Because the rotating seat 322 is movably connected to the linkage cylinder 312, the range of position change of the linkage cylinder 314 when it is threadedly linked with the rotating seat 322 can be limited. This also conforms to the characteristics of the elastic element 307 and prevents overpressure. As the drilling load on the drill bit 302 and the cable tray decreases, the speed of drill rod 1 303 will gradually be synchronized with the speed of drill rod 2 304. At this time, the linkage cylinder 314 will no longer be linked by the thread of thread 2, and under the action of the elastic element 307, the linkage cylinder 314 can be reset to the thread 2, thereby reducing the resistance between the first obstruction pad 305, the second obstruction pad 310 and the hollow cylinder 311, so that the second obstruction pad 310 and the hollow cylinder 311 can be used for a longer time.

[0058] refer to Figure 8One end of the second linkage cylinder 313 near the third linkage cylinder 314 is milled with a curved slope 317 and a limiting block 319 is configured. One end of the third linkage cylinder 314 near the second linkage cylinder 313 is milled with a curved slope 318 and a guide channel 320. The limiting block 319 is located on the curved slope 318, wherein the slope distance of the curved slope 318 is greater than the slope distance of the curved slope 317, and the bottom end of the limiting block 319 is located beyond the lowest position of the curved slope 317. The guide channel 320 is used for the movement of the limiting block 319, wherein the bottom of the limiting block 319 is not in contact with the surface of the guide channel 320.

[0059] refer to Figure 8 As shown, when the bottom end of the limiting block 319 is located at the lowest surface of the second curve slope 318, the linkage cylinder 314 can extend, retract, or rotate.

[0060] refer to Figure 9 As shown, when the rotational speed of drill rod 303 decreases, the speed of linkage cylinder 314 is greater than that of linkage cylinder 2 313. At this time, the edge of the curve slope 2 318 is in contact with the limiting block 319. Under the action of the synchronous rotation of linkage cylinder 2 313 and drill rod 303, linkage cylinder 314 and thread 2 undergo threaded movement, causing linkage cylinder 2 313 to undergo telescopic movement to compress the elastic element 307, thereby increasing the resistance force between the first blocking pad 305, the second blocking pad 310 and the hollow cylinder 311, thereby improving the blocking force and linkage effect.

[0061] refer to Figure 10 As shown, when the resistance of drill rod 303 gradually decreases or disappears, and the rotation speed of drill rod 303 and drill rod 304 is the same or zero, thread 2 does not engage in threaded transmission with linkage cylinder 314. Under the action of the elastic element 307 itself and the special shapes of curve slope 317 and curve slope 318, linkage cylinder 314 is gradually pushed and reset by rotation. With the gradually slowing squeezing action, linkage cylinder 314 gradually and slowly reaches the junction of thread 3 and thread 2, and slowly and rotatingly enters the inner edge of thread 2. At this time, elastic element 307 resets synchronously, avoiding the high resistance between obstruction pad 305, hollow cylinder 311 and obstruction pad 310. When this device is used, the linkage cylinder 314 is slowly reset. During the test, the linkage cylinder 314 rarely stops resetting due to the structure. Since the load force on drill bit 302 during operation is an unstable value, this phenomenon can be ignored.

[0062] It should be noted that in this scheme, the limiting relationships between the push cylinder 306 and drill rod 1 303, the hollow cylinder 311 and drill rod 2 304, and the linkage cylinder 2 313 and drill rod 1 303 are all the same.

[0063] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those of ordinary skill in the art who benefit from this disclosure, the development effort will be a routine task in design, manufacturing, and production without requiring extensive experimentation.

[0064] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
