Description

Technical Field

[0001] The utility model relates to the technical field of frame side processing devices, in particular to a rail trolley type bridge frame side wall opening device. Background Art

[0002] In factory or building projects, it is usually necessary to lay cables through a bridge. Therefore, holes must be drilled on the side walls of the bridge and wire conduits must be installed to allow the cables to be led out of the bridge. During the installation, tracks are installed on the side walls of the bridge to drive the bridge to move. At the same time, since the tracks are installed on the side walls, safety accidents may occur when workers drill holes in the side walls. For this reason, we use side wall hole opening devices to assist in hole opening.

[0003] In the side wall hole drilling device, a track trolley is installed on the track. The track trolley can push the hole drilling device to different areas to control the drilling device to drill holes at different positions on the side wall. When drilling holes on the side wall, in order to ensure the uniformity of the holes, it is necessary to control the distance between the drilling positions at the upper and lower ends of the side wall and the track to be the same. The track trolley uses a position adjustment device to move the drilling device up and down. However, when the position adjustment device continuously adjusts the position of the drilling device, the position adjustment device will be worn, and then the friction of the device will cause the hole position to shift. After the hole position is opened, it is not convenient to subsequently fix the wire conduit. For this reason, we propose a track trolley type bridge side wall hole drilling device. Utility Model Content

[0004] In view of the shortcomings of the existing rail trolley type bridge frame side wall hole opening device, the utility model provides a rail trolley type bridge frame side wall hole opening device, which has the advantage of starting a second lead screw, and the second lead screw drives the slide rod to adjust the position inside the limit sleeve. At the same time, the slide rod drives the drilling device to drill a hole on the upper end of the side wall, and then starts the gear motor to drive the disc to rotate. At the same time, the disc drives the drilling device to flip to the other end, and then the drilling position can be driven to maintain the same state as the position between the rails, thereby solving the problems raised in the above-mentioned background technology.
