These different types of bridges have their own characteristics and application fields. They can be erected independently or laid on various buildings and pipe gallery brackets. Their main characteristics are simple structure, beautiful shape, flexible configuration and easy maintenance. Since most cable bridges are stamped from thin plates, the cable bridges will produce violent vibrations during the cutting process.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1The utility model provides an embodiment: a cutting fixture for cable bridge processing, including a base 1, the inner wall of the top end of the base 1 is rotatably connected to a roller 2 to reduce the friction between the base 1 and the trough type cable bridge, and can fix the trough type cable bridge while ensuring that the trough type cable bridge can move forward and backward. A cutting device body 3 is arranged in the middle of the top end of the base 1 for cutting the trough type cable bridge. The base 1 is fixedly connected to support frames 4 on both sides close to the cutting device body 3 for supporting the limiting component. An electric push rod 5 is fixedly connected to the top end of the support frame 4, and the limiting component is driven up and down by the electric push rod 5 to make it in close contact with the cable bridge and apply appropriate pressure. This pressure can effectively prevent the cable bridge from moving or vibrating during the cutting process, thereby improving the cutting accuracy and safety.

[0032] Reference Figure 1 and Figure 2 The inner wall of the support frame 4 is provided with a limiting component, which includes a support block 61, the upper outer wall of the support block 61 is slidably connected to the inner wall of the support frame 4, the right side of the top of the support block 61 is fixedly connected to the top of the output shaft of the electric push rod 5, the inner wall of the support block 61 is rotatably connected to a rotating rod 62, and the top of the rotating rod 62 is provided with a rotating handle, which can facilitate the operator to rotate the rotating rod 62, the bottom end of the rotating rod 62 is fixedly connected to a worm gear 63, and the front end of the worm gear 63 is meshed with a worm 64, and the two groups of worm gears 64 are driven by the worm gear 63 to rotate, thereby driving multiple groups of threaded rods 65 to rotate, so that multiple groups of sliders 66 slide out from the inner wall of the support block 61, and the two ends of the worm gear 64 are rotatably connected to the inner wall of the support block 61, and the two ends of the worm gear 64 are fixedly connected to the threaded rod 65, and the inner wall of the bottom end of the support block 61 is slidably connected to a slider 66, which is used to drive a roller 67 to limit the trough-type cable tray, and the outer wall of the threaded rod 65 is threadedly connected to the inner wall of the slider 66.

[0033] Reference Figure 2 and Figure 3 There are two groups of sliders 66, and the outer sides of the two groups of sliders 66 are rotatably connected with roller one 67. Roller one 67 can correspond to roller two 72 on the slide plate 71, and contact with the surface of the trough type cable tray in a rolling manner, which can reduce friction and ensure that the cable tray is evenly stressed during the clamping process to avoid deformation caused by excessive local pressure. There are two groups of worm gears 63, and the two groups of worm gears 63 are respectively arranged on the rotating rod 62 near the slider 66. Two groups of stabilizing wheels are arranged at the bottom of the support block 61, so that the operator can easily push or drag the trough type cable tray, which improves work efficiency and reduces operation difficulty and labor intensity.

[0034] Reference Figure 1 and Figure 4A clamping assembly is provided on the inner wall of the base 1 near the support frame 4, and the clamping assembly includes a slide plate 71. The outer wall of the bottom end of the slide plate 71 is slidably connected to the inner wall of the base 1. The right side of the slide plate 71 is rotatably connected to a roller 2 72. The rolling contact mode of the roller 2 72 significantly reduces the friction with the outer wall of the trough-type cable tray. Compared with the traditional fixed clamping mode, the rolling contact can greatly reduce the friction resistance generated during the clamping and moving process, which not only helps to protect the surface of the cable tray from scratches or wear, but also can reduce the wear of the clamping assembly and extend its service life.

[0035] Reference Figure 4 The inner wall of the base 1 is rotatably connected with a double-screw twisted rod 73, and two groups of slide plates 71 are provided. The two groups of slide plates 71 are symmetrically arranged with the center line of the double-screw twisted rod 73 as the symmetry axis. Through the cooperation of the double-screw twisted rod 73 and the slide plate 71, adaptive clamping of trough-type cable trays of different specifications can be achieved. A handle 74 is fixedly connected to the right side of the double-screw twisted rod 73, which is convenient for the operator to rotate the double-screw twisted rod 73.

[0036] Working principle: When in use, first place the trough type cable tray on the roller 2, move the trough type cable tray to the position where cutting is required, then turn the handle 74 to drive the double screw twisted rod 73 to rotate on the inner wall of the base 1, thereby driving the slide plate 71 to slide on the inner wall of the base 1, so that the roller 2 72 contacts the outer wall of the trough type cable tray.

[0037] At this time, the electric push rod 5 is started to drive the support block 61 to descend, so that the stabilizing wheel at the bottom end of the support block 61 is in contact and limited with the trough type cable tray. At this time, the handle on the rotating rod 62 is turned to drive the rotating rod 62 to rotate on the inner wall of the support block 61, and at the same time drive the worm wheel 63 to rotate, so that the worm wheel 63 drives the worm 64 to rotate, so that the worm 64 drives the two groups of threaded rods 65 to rotate on the inner wall of the slider 66, and drives the two groups of sliders 66 to move to both sides, so that roller 1 67 is in contact with the trough type cable tray, and the trough type cable tray is clamped and limited by roller 2 72 and roller 1 67, so as to effectively reduce the vibration of the trough type cable tray during cutting. At this time, the cutting device body 3 is started to cut the trough type cable tray.

[0038] When the cut trough type cable tray needs to be removed, it is only necessary to turn the handle to release the restriction of the roller 1 67 on the trough type cable tray, and the trough type cable tray can be removed through the roller 2 and the roller 2 72, thereby improving the efficiency of removing the trough type cable tray.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
