Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, specifically to an automatic cutting device for power construction cable trays. Background Technology

[0002] Cable trays are structures used to support, fix, and protect cable lines. They are widely used in the laying of power, communication, and control cables in buildings, industrial plants, data centers, transportation facilities, and other places. Depending on the requirements of different locations, cable trays need to be cut using cutting devices to match specific dimensions. The most common cutting method is to use a circular saw blade.

[0003] As in the prior art, Chinese Patent Application No. CN202210533407.5 discloses a cable tray cutting device for electrical engineering installation, including a frame, a cutting mechanism movably mounted on the frame, an L-shaped block on the bottom side of the frame, and an angle adjustment mechanism on the L-shaped block; the angle adjustment mechanism includes a first hinge rod and a second hinge rod, a third hinge rod hinged to the end of the first hinge rod away from the L-shaped block, and a fourth hinge rod hinged to the end of the second hinge rod away from the L-shaped block. The first hinge rod and the second hinge rod are parallel to each other, and the third hinge rod and the fourth hinge rod are parallel to each other. The second hinge rod and the third hinge rod intersect each other, and the intersection point of the second hinge rod and the third hinge rod is hinged to each other. The end of the third hinge rod away from the first hinge rod and the end of the fourth hinge rod away from the second hinge rod are both fixedly connected to one end of the cutting mechanism. The L-shaped block is provided with a driving component for driving the first hinge rod to rotate.

[0004] For example, in the prior art, Chinese Patent Application No. CN202211645682.2 discloses a cutting machine for cable tray processing, belonging to the field of cable tray processing technology. It includes a placement platform and a support frame, and further includes: a collection box, which is fixedly mounted on the upper end of the placement platform, and the upper end of the collection box is provided with an annular through hole. A support plate is provided in the middle of the upper end of the collection box, and the support plate is fixedly connected to the inner wall of the collection box by a fixing column; a clamping assembly, which is connected to the support plate by a rotating assembly; a protective plate, which is fixedly provided on the periphery of the upper end of the collection box; and a cutting assembly, which is connected to the support frame by a moving assembly.

[0005] For example, in the prior art, Chinese patent application number CN202110533962.3 discloses a cable tray production cutting device, including a workbench, with clamping mechanisms stacked at both ends of the top of the workbench, and a cutting mechanism located between the two clamping mechanisms on the top of the workbench; the clamping mechanism consists of a support platform, a vertical plate, a first lead screw, a threaded sleeve, and a movable plate, with the vertical plates symmetrically arranged on the top of the support platform, the threaded sleeves symmetrically embedded in the vertical plates, and the first lead screw installed inside the threaded sleeves, the movable plate located between the vertical plates, and the movable plate rotatably connected to the first lead screw; a first support plate is fixed on the top of one support platform, and an electric telescopic rod is fixed on the top of the first support plate.

[0006] Based on the above information, it can be seen that the existing technology generally uses a cutting platform with a circular saw blade to cut cable trays. However, in actual use, the existing devices generally require manual determination of the cutting length, moving the cable tray to the designated position before cutting. The entire process involves a large amount of manual operation and has a low degree of automation. Summary of the Invention

[0007] The purpose of this invention is to provide an automatic cutting device for power construction cable trays to solve the problem of low automation mentioned in the background art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an automatic cutting device for power construction cable trays, comprising a cutting platform placed horizontally on the ground, a support frame and a power box fixedly installed on the upper surface of the cutting platform, and a cutting saw blade installed on the front side of the support frame. A water collection tank is provided on the upper surface of the cutting platform, and a first support seat and a second support seat are provided inside the water collection tank. The first support seat and the second support seat are slidably connected to an electric slide rail fixedly installed inside the water collection tank. A clamping roller driven by a motor is rotatably installed above the first support seat and the second support seat. The cable tray body is clamped between the front and rear clamping rollers. The first support seat and the second support seat drive the cable tray body to move back and forth and automatically cut using the cutting saw blade. A cooling nozzle aligned with the cutting saw blade is fixedly installed on the side of the second support seat, and the cooling nozzle is connected to a water supply tank through a first connecting pipe. A recycling mechanism for recycling cooling water is provided inside the cutting platform.

[0009] Preferably, the recycling mechanism includes a filter chamber located inside the upper part of the cutting platform, and the filter chamber is connected to the water collection tank through a through hole on its upper part.

[0010] Preferably, a recycling bin is provided at the right end of the cutting platform, and a filter screen structure is fixedly installed at the connection position between the recycling bin and the filter bin, and the recycling bin is connected to the water supply tank through a second connecting pipe.

[0011] Preferably, the lower end of the cutting platform is provided with a chip collection bin for collecting cutting debris, and a movable plate is installed between the chip collection bin and the filter bin.

[0012] Preferably, the upper surface of the movable plate is configured as an inclined structure, and a sealing ring for separating the filter chamber and the chip collection chamber is fixedly installed on the side of the movable plate.

[0013] Preferably, an electromagnet for adsorbing metal cutting debris is fixedly installed on the upper surface of the movable plate, and the upper surface of the electromagnet is provided with a raised strip to increase the contact area.

[0014] Preferably, a mounting frame is fixedly installed inside the chip collection bin, and a telescopic cylinder is fixedly installed between the mounting frame and the movable plate.

[0015] Preferably, a connecting rod is fixedly installed at the middle position of the lower surface of the movable plate, and the connecting rod is slidably connected to the mounting frame through it.

[0016] Preferably, a contact strip is fixedly installed on the outer surface of the lower end of the connecting rod, and the contact strip makes contact with and is energized with a contact block fixedly installed inside the fixing frame, and the contact strip is electrically connected to the electromagnet.

[0017] Preferably, a convex ball is fixedly installed on the outer surface of the upper end of the connecting rod, and the convex ball squeezes the mounting frame to generate vibration.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the automatic cutting equipment for power construction cable trays adopts a novel structural design, the specific details of which are as follows: 1. During the cutting process, the main body of the cable tray to be cut is placed on the first support and the second support. The clamping rollers on the first and second support are used to clamp the main body of the cable tray. Then, the main body of the cable tray is moved closer to the cutting saw blade by the sliding of the first and second support on the electric slide rail, so as to achieve the purpose of automatic cutting. The clamping rollers are driven by the motor to rotate, so as to realize the automatic transport of the main body of the cable tray.

[0019] 2. During the cutting process, the cooling water in the water supply tank is delivered to the cooling nozzle through the first connecting pipe and sprayed out. The sprayed cooling water is used to cool the cutting position, reduce sparks, lubricate the cutting position, and protect the main body of the cable tray. The cooling water enters the filter chamber through the through hole, and after being filtered by the filter screen, it flows into the recycling chamber for storage. Furthermore, metal debris mixed in the cooling water is attracted to the surface of the moving plate by the electromagnet, thereby collecting and recycling the metal debris and reducing the filtration burden on the subsequent filter screen.

[0020] 3. The movable plate is moved downward by the telescopic cylinder, so that the movable plate is released from the seal on the upper end of the chip collection bin. The movable plate also moves the connecting rod downward in sync. When the metal block is released from contact with the metal strip, the power supply to the electromagnet is automatically cut off. At this time, the metal chips above the movable plate fall into the chip collection bin. Furthermore, as the connecting rod moves downward, the convex ball presses against the mounting bracket, causing the mounting bracket to vibrate and making the debris on the movable plate fall off more thoroughly.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please refer to Figures 1-3 In order to improve the degree of automation, this embodiment provides the following technical solution, which specifically discloses: a cutting platform 1 placed horizontally on the ground, a support frame 2 and a power box 4 fixedly installed on the upper surface of the cutting platform 1, and a cutting saw blade 3 installed on the front side of the support frame 2. A water collection tank 5 is provided on the upper surface of the cutting platform 1, and a first support seat 6 and a second support seat 7 are provided inside the water collection tank 5. The first support seat 6 and the second support seat 7 are slidably connected to an electric slide rail 10 fixedly installed inside the water collection tank 5. A clamping roller 8 driven by a motor is rotatably installed above the first support seat 6 and the second support seat 7. The bridge frame body 9 is clamped between the front and rear clamping rollers 8. The first support seat 6 and the second support seat 7 drive the bridge frame body 9 to move back and forth and automatically cut using the cutting saw blade 3.

[0025] When using the device, the main body 9 of the cable tray to be cut is first placed on the first support 6 and the second support 7. The clamping rollers 8 on the first support 6 and the second support 7 clamp the main body 9 of the cable tray. Then, the clamping rollers 8 are driven by a motor to rotate, and the clamping rollers 8 are used to move the main body 9 of the cable tray left and right. With the help of infrared equipment, the positioning is precise. After the positioning is completed, the first support 6 and the second support 7 drive the electric slide rail 10 to slide, and move the main body 9 of the cable tray close to the cutting saw blade 3 to achieve the purpose of automatic cutting. After a section of cutting is completed, the clamping rollers 8 rotate again to position it. In the whole process, the operator only needs to load and unload the material. The overall degree of automation is high.

[0026] Example 2: Please refer to Figure 4 In order to achieve the purpose of waste liquid recycling, this embodiment provides the following technical solution, which specifically discloses: a cooling nozzle 11 aligned with the cutting saw blade 3 is fixedly installed on the side of the second support base 7, and the cooling nozzle 11 is connected to the water supply tank 13 through the first connecting pipe 12. The cutting platform 1 is provided with a recycling mechanism for recycling cooling water. The recycling mechanism includes a filter chamber 14 opened at the upper end of the inside of the cutting platform 1, and the filter chamber 14 is connected to the water collection tank 5 through the through hole 15 opened above it. A recycling chamber 16 is opened at the right end of the inside of the cutting platform 1, and a filter screen structure is fixedly installed at the connection position between the recycling chamber 16 and the filter chamber 14. The recycling chamber 16 is connected to the water supply tank 13 through the second connecting pipe 17.

[0027] During the cutting process, a water pump is used to transport cooling water from the water supply tank 13 to the cooling nozzle 11 through the first connecting pipe 12. Then, the cooling nozzle 11 sprays cooling water to cool and lubricate the cutting position. The wastewater after use enters the water collection tank 5 and enters the filter chamber 14 through the through hole 15. After being filtered by the filter screen on the right side of the filter chamber 14, it enters the recycling chamber 16 for storage. The water pump can transport the water in the recycling chamber 16 to the water supply tank 13 through the second connecting pipe 17 for reuse.

[0028] Example 3: Please refer to Figures 5-9 To achieve the purpose of collecting metal scrap, this embodiment provides the following technical solution, specifically: a scrap collection bin 18 is provided at the lower end of the cutting platform 1 for collecting cutting scrap, and a movable plate 19 is installed between the scrap collection bin 18 and the filter bin 14. The upper surface of the movable plate 19 is set with an inclined structure, and a sealing ring 22 for separating the filter bin 14 and the scrap collection bin 18 is fixedly installed on the side of the movable plate 19. An electromagnet 23 for adsorbing metal cutting scrap is fixedly installed on the upper surface of the movable plate 19, and a protrusion 24 for increasing the contact area is provided on the upper surface of the electromagnet 23. A mounting frame 20 is fixedly installed inside the chip collection bin 18, and a telescopic cylinder 21 is fixedly installed between the mounting frame 20 and the movable plate 19. A connecting rod 25 is fixedly installed at the middle position of the lower surface of the movable plate 19, and the connecting rod 25 is slidably connected to the mounting frame 20. A contact strip 26 is fixedly installed on the outer surface of the lower end of the connecting rod 25, and the contact strip 26 contacts and is energized with a contact block 27 fixedly installed inside the mounting frame 20. The contact strip 26 is also electrically connected with an electromagnet 23. A convex ball 28 is fixedly installed on the outer surface of the upper end of the connecting rod 25, and the convex ball 28 squeezes the mounting frame 20 to generate vibration.

[0029] After cooling water enters the filter chamber 14, the electromagnet 23 above the movable plate 19 adsorbs the metal debris mixed in the cooling water. After a period of use, during the idle time of the device, the telescopic cylinder 21 above the mounting frame 20 is opened. The telescopic cylinder 21 drives the movable plate 19 to move downward, causing the movable plate 19 to disengage from the seal at the top of the chip collection chamber 18. During the downward movement of the movable plate 19, the connecting rod 25 moves downward synchronously. When the contact bar 26 moves to the position where it disengages from the contact block 27, the power supply to the electromagnet 23 is disconnected. At this time, the electromagnet 23 loses its magnetism, and the metal debris adsorbed on the movable plate 19 falls into the chip collection chamber 18 under the action of gravity. During the continuous downward movement of the connecting rod 25, the convex ball 28 at its upper end intermittently squeezes the mounting frame 20, causing the mounting frame 20 to vibrate and completely shake off the metal debris above the movable plate 19.

[0030] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
