Technical Field

[0001] The utility model relates to the technical field of hole opening equipment, in particular to a hole opening device for a side wall of a cable bridge. Background Art

[0002] Cable tray is a trough-type metal frame, which is mainly used as a carrier for placing cables in buildings. There are many types of cable trays, some of which are installed on the wall, and some are hung on the top wall of the building through a hanger. In factories or building projects, holes must always be opened on the side walls of the cable tray to install threading tubes so that the cables can be led out of the cable tray. In order to facilitate the opening of holes in the side walls of the track cable tray, a hole opening device is required;

[0003] The utility model with application number 202320607075.0 discloses a wall-mounted cable tray side wall opening device, which can form a punching and opening mechanism of the entire opening device through the cooperation of a frame, a frame-shaped clamp, a hydraulic rod, a punching shaft and a perforation, so that the opening of the cable tray can be achieved by clamping and punching. The punching and opening mechanism can be lifted and lowered through the cooperation of a sleeve, an extension rod, a motor, a first bevel gear, a screw, a second bevel gear, a driving block and a connecting frame, so that the punching and opening mechanism can be extended to the cable tray and punch and open the cable tray at a long distance, thereby making the opening of the cable tray more convenient;

[0004] However, the above-mentioned wall-mounted cable tray side wall hole opening device is unable to open holes for cable trays of different widths. The above-mentioned wall-mounted cable tray side wall hole opening device can only open holes on one side of the cable tray at a time. When holes need to be opened on both sides, the position needs to be changed again, which makes the hole opening accuracy difficult and easily leads to asymmetric holes on both sides. Therefore, the utility model proposes a cable tray side wall hole opening device to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

A laser indicator 8 is fixedly provided on the inner side of the slider 4, and a symmetrical hole opening mechanism is provided above the slider 4. Before opening a hole, the base 1 is pushed to move to the bottom of the cable tray, and the laser indicator 8 is turned on. At the same time, the first motor 7 starts to drive the bidirectional threaded rod 5 to rotate through the first threaded sleeve 6 to drive the slider 4 and the laser indicator 8 to move toward each other along the slide rail 3. When it is observed that the laser beam is in contact with both sides of the cable tray, the first motor 7 stops, so that precise movement and adjustment can be achieved according to the width of the cable tray, which solves the problem of not being able to open holes for cable trays of different widths.

[0019] The lifting mechanism includes a fixed section 13, a lifting section 14, a third motor 15, a screw 16, a second threaded sleeve 17, a sliding rod 18 and a sliding sleeve 19. The fixed section 13 is fixedly provided with a middle bolt on the base 1. The lifting section 14 is lifted and lowered on the upper end of the fixed section 13. The third motor 15 is fixedly provided at the bottom of the fixed section 13. The output end of the third motor 15 is driven by a screw 16. The screw 16 is threadedly sleeved with a second threaded sleeve 17. The outer side of the second threaded sleeve 17 is fixedly connected to the inner wall of the lifting section 14. Slide rods 18 are symmetrically fixed at the bottom of the part, and sliding sleeves 19 are symmetrically fixed on both sides of the fixed section 13. The slide rods 18 slide through the sliding sleeves 19 for guidance, and the upper end of the screw rod 16 extends into the lifting section 14 and fits with the inner wall of the lifting section 14 to maintain stability. After the positions are aligned, the third motor 15 starts to drive the screw rod 16 to rotate, and the second threaded sleeve 17 cooperates with the screw 16 to drive the lifting section 14 to rise. At the same time, the slide rod 18 moves upward along the sliding sleeve 19 with the lifting section 14 to keep the lifting section 14 stable. When the third motor 15 rises to the corresponding height of the cable tray, it stops.

[0020] The symmetrical hole opening mechanism includes a hole opening frame 9, a second motor 10, a hole opener 11 and a magnet 12. The slider 4 is equipped with a second motor 10, and the output end of the second motor 10 drives the hole opener 11. The hole opener 11 is fixed with a magnet 12. When opening a hole, the lifting section 14 drives the adjustment frame 2 to rise to the corresponding position below the cable tray, and then the second motor 10 starts to drive the hole opener 11 to rotate. At the same time, the first motor 7 starts to drive the two-way threaded rod 5 to rotate slowly, driving the slider 4 and the hole opening frame 9 to move toward each other to open a hole. The waste generated by the hole opening is adsorbed on the magnet 12. After the hole opening is completed, the first motor 7 drives the two-way threaded rod 5 to reverse so that the slider 4 drives the hole opening frame 9 to move away to complete the hole opening.

[0021] Universal wheels 20 are mounted on the four corners of the base 1 , and a handle 21 is fixedly disposed on the rear side of the base 1 . When the base 1 needs to be moved, the handle 21 is pushed, and the universal wheels 20 drive the base 1 to move.

[0022] The cable tray side wall hole opening device pushes the handle to make the base move to the bottom of the cable tray driven by the universal wheel, turns on the laser indicator to emit a laser, and the first motor starts to drive the bidirectional threaded rod to rotate, which is driven by the first threaded sleeve to drive the slider to move toward each other along the slide rail. When the laser is irradiated to the bottom of the cable tray and aligned, the first motor stops, and the third motor starts to drive the screw to rotate, which is driven by the second threaded sleeve thread to drive the lifting section to rise, and the sliding synchronously moves along the sliding sleeve to keep the lifting section stable. The adjustment frame is lifted to the bottom of the cable tray under the push of the lifting section, and the second motor starts to drive the hole opener to rotate. At the same time, the first motor starts to drive the bidirectional threaded rod to rotate slowly, driving the hole opener to move toward each other to open a hole. After the hole is opened, the waste is adsorbed on the magnet, and the first motor drives the bidirectional threaded rod to rotate in the opposite direction to move the hole opener outward to complete the hole opening.
