Description

Technical Field

[0001] This utility model relates to the field of cable tray cutting technology, specifically to a cable tray cutting device for electrical engineering installation. Background Technology

[0002] Cable trays are available in various structures, including trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building structures and pipe rack supports. They should feature simple structure, aesthetically pleasing appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also suitable for such installations. During electrical engineering installations, a large number of cable trays are required. To adapt to the actual installation locations on the construction site, it is often necessary to cut and trim the cable trays.

[0003] Patent publication number CN217749565U discloses a cable tray cutting device for electrical engineering installation. This patent uses a first clamp and a second clamp to cooperate to support and fix the outer wall of the cable tray, and a support plate to support and fix the inner wall of the cable tray. This makes it less likely for the cable tray to deform when placed on the frame for cutting, and it is more convenient to connect the cut surfaces of the cable tray. However, this patent still has the following problems in actual use: The outer wall of the cable tray is supported and fixed by the cooperation of the first and second clamps. However, in actual use, when cutting a long section of cable tray, the cable tray is usually divided into multiple sections. After one section of the cable tray is cut, the first and second clamps need to be manipulated to loosen the remaining cable tray. Then, the remaining cable tray is moved to continue cutting. When continuously cutting a long section of cable tray, it is necessary to repeatedly loosen and fix the cable tray, which is not convenient for continuous cutting by tapping the cable and results in low cutting efficiency.

A movable plate is fixedly installed on the movable end of the electric push rod, and a support frame is fixedly installed on one side of the bottom of the movable plate. A disc cutter mechanism is provided below the support frame. The top of the workbench has a cutting groove extending through it below the disc cutter mechanism, and limit frames are symmetrically installed on both sides of the bottom of the movable plate. Positioning blocks are slidably connected to the lower outer sides of the two limit frames, and the positioning blocks are fixedly connected to the fixed frame. A fixing component is provided on one side of the fixed frame on the top of the workbench.

[0012] Preferably, the guide groove on the guide frame is divided into a vertical section and an inclined section, and the top of the worktable is provided with a through groove located below the two guide frames.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This cable tray cutting equipment for electrical engineering installation enables the automatic positioning and loosening of the cable tray body through the movement of the movable plate during continuous cutting. This eliminates the need for repeated loosening and fixing of the cable tray body during continuous cutting, thus improving the cutting efficiency of the cable tray body. The specific details are as follows: 1. When cutting the cable tray body, place the cable tray body in the strip groove and adjust its position so that the cutting position is below the disc cutter cutting mechanism. The disc cutter cutting mechanism drives the disc cutter to rotate via a servo motor, which in turn drives the electric push rod to move the movable plate downwards. Simultaneously, the movable plate moves downwards via a limit bracket, causing the connecting bracket to move downwards, which in turn moves the guide bracket downwards. At this time, the inclined guide groove on the guide bracket can push the mounting rod to move, causing the movable rod to slide on the mounting bracket and compress the telescopic spring, thus moving the positioning plate to align with the outer side of the cable tray body. After the contact plate is closed, the movable plate continues to move downwards, allowing the guide frame to be inserted into the through slot. The mounting rod can slide on the vertical section of the guide slot. The downward movement of the movable plate allows the disc cutting blade to cut the cable tray body. After cutting, the movable plate is reset, and the positioning plate is reset by the telescopic spring, which can automatically release the cable tray body. This allows the cable tray body to be automatically positioned and released during continuous cutting by the movement of the movable plate. This eliminates the need to repeatedly release and fix the cable tray body during continuous cutting, improving the cutting efficiency of the cable tray body. 2. When positioning the cable tray body, the movement of the positioning plate can drive the movement of one side column. The movement of one side column can slide inside the movable slot on the rotating frame, which can push the rotating frame to rotate. After the rotating frame rotates, the other side column slides in the movable slot on the other side, which can drive the clamping plate to move and press against the inner side of the cable tray body. This allows the positioning plate to simultaneously clamp and fix the inner and outer sides of the cable tray body, providing stable support for the cable tray body and improving the stability of the cable tray body during cutting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a cable tray cutting device for electrical engineering installation, including a workbench 1, a strip groove 101 on the top of the workbench 1, and a cable tray body 102 inside the strip groove 101. It also includes: a fixing frame 103 fixedly installed on one side of the top of the workbench 1, an electric push rod 104 fixedly installed on the top of the fixing frame 103, a movable plate 105 fixedly installed on the movable end of the electric push rod 104, a support frame 106 fixedly installed on one side of the bottom of the movable plate 105, and a disc cutter cutting mechanism 107 arranged below the support frame 106. A cutting groove is formed through the top of the workbench 1 below the disc cutter cutting mechanism 107, and the bottom sides of the movable plate 105 are symmetrically equipped with... There is a limiting frame 108, and a positioning block 109 is slidably connected to the lower part of the two limiting frames 108. The positioning block 109 is fixedly connected to the fixed frame 103. A fixing component 2 is provided on the top of the workbench 1 on one side of the fixed frame 103. The fixing component 2 includes two mounting brackets 201 fixedly installed on the top of the workbench 1 on one side of the fixed frame 103. Movable rods 202 are symmetrically slidably connected through both sides of the interior of the two mounting brackets 201. This allows the positioning and release of the cable tray body 102 to be automatically realized by the movement of the movable plate 105 when the cable tray body 102 is continuously cut. During continuous cutting, it is not necessary to repeatedly release and fix the cable tray body 102, thereby improving the cutting efficiency of the cable tray body 102.

[0018] Each of the two movable rods 202 on each side has a positioning plate 203 fixedly installed at one end near the center of the worktable 1, and a fixing block 205 fixedly installed at the other end of each movable rod 202. A telescopic spring 204 is sleeved on the outside of each movable rod 202 on one side of the fixing block 205, and both ends of the telescopic spring 204 are fixedly connected to the fixing block 205 and the mounting bracket 201 respectively, facilitating the reset of the movable rod 202 after movement. An mounting rod 206 is fixedly installed between each of the two fixing blocks 205 on each side. A connecting bracket 207 is fixedly installed on one side of each of the two limiting brackets 108 below the positioning block 109, and a guide bracket 208 is fixedly installed on the bottom side of the connecting bracket 207. A guide groove is formed through one side of the guide bracket 208, and the mounting rod 206 is slidably connected to the guide groove on the guide bracket 208, allowing the movement of the guide bracket 208 to move the mounting rod 206. Positioning brackets are symmetrically installed on the top inner sides of each of the two mounting brackets 201. 209, and each of the two positioning frames 209 on the front and rear sides has a sliding rod 210 connected through it. Each of the two moving rods 210 on each side has a clamping plate 211 fixedly installed at the end near the positioning plate 203 to support the moving rod 210. Fixed rods 212 are symmetrically installed above the two mounting frames 201, and the bottom of each of the two fixed rods 212 is rotatably connected to a rotating frame 213 to support the rotating frame 213. The top of the rotating frame 213 has symmetrically through-cut movable slots 214, and each of the two movable slots 214 has a sliding column rod 215 connected inside it. The two column rods 215 are fixedly connected to the clamping plate 211 and the positioning plate 203 respectively, so that the clamping plate 211 and the positioning plate 203 can move closer or further away at the same time. The guide slot on the guide frame 208 is divided into a vertical section and an inclined section. The top of the workbench 1 is through-cut below the two guide frames 208, so that the guide frame 208 can continue to move down after the bridge frame body 102 is fixed.

[0019] Working principle: Before using this type of cable tray cutting equipment for electrical engineering installation, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 4As shown, when cutting the cable tray body 102, the cable tray body 102 is placed in the strip groove 101, and the position of the cable tray body 102 in the strip groove 101 is adjusted so that the cutting position is below the disc cutter cutting mechanism 107. The disc cutter cutting mechanism 107 drives the disc cutter to rotate by starting the servo, and starts the electric push rod 104 to drive the movable plate 105 to move down. At the same time as the movable plate 105 moves down, it drives the connecting frame 207 to move down through the limit frame 108, so that the guide frame 208 moves down. At this time, the inclined guide groove on the guide frame 208 can push the mounting rod 206 to move, so that the movable rod 202 slides on the mounting frame 201 and compresses the telescopic spring 204, so that the positioning plate 203 moves with the cable tray. The outer side of the main body 102 is abutted and fitted, and then the movable plate 105 continues to move down, the guide frame 208 can be inserted into the through groove, and the mounting rod 206 can slide on the vertical section of the guide groove. Then the movable plate 105 moves down so that the disc cutting blade can cut the cable tray main body 102. After the cutting is completed, the movable plate 105 is reset, and the positioning plate 203 is reset by the telescopic spring 204, which can automatically release the cable tray main body 102. When the cable tray main body 102 is continuously cut, the positioning and release of the cable tray main body 102 can be automatically realized by the movement of the movable plate 105. When the cable tray main body 102 is continuously cut, it is not necessary to repeatedly release and fix the cable tray main body 102, thus improving the cutting efficiency of the cable tray main body 102. When positioning the cable tray body 102, the movement of the positioning plate 203 can drive the movement of one side column 215. The movement of one side column 215 can slide inside the movable groove 214 on the rotating frame 213, so that the rotating frame 213 can be pushed to rotate. After the rotating frame 213 rotates, the other side column 215 slides in the other side movable groove 214, so that the clamping plate 211 can move and press against the inner side of the cable tray body 102. This allows the positioning plate 203 to simultaneously clamp and fix the inner and outer sides of the cable tray body 102. Both the positioning plate 203 and the clamping plate 211 are made of rubber. When the cable tray body 102 is fixed, it is squeezed and deformed, which can provide stable support for the cable tray body 102 and improve the stability of the cable tray body 102 during cutting.

[0020] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
