Description

Technical Field

[0001] This utility model relates to the field of elevator track processing technology, and in particular to a drilling device for elevator track processing. Background Technology

[0002] Elevator rails are a key component of elevator systems, primarily used to guide and support the vertical movement of the elevator car and counterweight. The manufacturing process of elevator rails includes material preparation, cutting, forming, drilling, heat treatment, surface treatment, and quality inspection. Drilling holes in the elevator rails is essential for installation, fixing, and adjustment, ensuring the rails are stable, vertical, and parallel, thereby guaranteeing the safe and stable operation of the elevator.

[0003] Because multiple holes need to be drilled on the elevator track, the existing elevator track processing and drilling process requires manual loosening and repositioning of the track after each drilling operation before the next drilling can be performed. This process is cumbersome, has low automation, and reduces work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drilling device for processing elevator tracks.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A drive mechanism is provided to drive the first lead screw and the second lead screw to rotate in sequence.

[0008] As a further technical solution of this utility model, a chip collection box is welded to one side of the bottom of the workbench, the top of the chip collection box is an open structure, a side door is hinged to the outside of the chip collection box, a chip drop opening is opened on the top of the chip collection box on the workbench, and support legs are vertically welded to both ends of the other side of the bottom of the workbench.

[0009] As a further technical solution of this utility model, a controller is fixedly installed on one side of the outside of the chip collection box, an L-shaped mounting bracket is welded to one side of the top of the workbench, a hydraulic telescopic rod is vertically fixedly installed on the top of the L-shaped mounting bracket, the telescopic end of the hydraulic telescopic rod passes through the L-shaped mounting bracket and is slidably connected to the L-shaped mounting bracket, a mounting base is fixedly installed at the bottom of the telescopic end of the hydraulic telescopic rod, a rotary motor is vertically fixedly installed at the bottom of the mounting base, and a drill bit is fixedly installed at the bottom of the output end of the rotary motor, with the drill bit located directly above the chip discharge port.

[0010] As a further technical solution of this utility model, both of the moving blocks are connected to the first lead screw by threads, the threads at both ends of the first lead screw are in opposite directions, both of the moving blocks are slidably connected inside the first groove, and the moving plate is connected to the second lead screw by threads, and the moving plate is slidably connected inside the second groove.

[0011] As a further technical solution of this utility model, the driving mechanism includes a forward and reverse motor. A mounting plate is vertically welded to the bottom of the worktable. The forward and reverse motor is horizontally fixedly mounted on one side of the mounting plate. A turntable is fixedly mounted on the output end of the forward and reverse motor. Multiple ratchet teeth are evenly welded to the outer periphery of a portion of the turntable. One end of the second lead screw extends out of the second slot and is welded with a second driven gear. A drive shaft is horizontally rotatably connected to one side of the mounting plate. A first driven gear is welded to the other end of the drive shaft. The first and second driven gears mesh with multiple ratchet teeth in sequence. A drive bevel gear is welded to the drive shaft. A driven bevel gear meshes with the side of the drive bevel gear. A driven shaft is horizontally welded to the center of the driven bevel gear. A horizontal plate is welded to one side of the worktable. The driven shaft passes through the horizontal plate and is rotatably connected to it. A large disc is welded to the other end of the driven shaft. A circular groove is formed on the other side of the large disc. A small disc is welded to the center of the circular groove. Multiple internal protruding teeth are evenly welded to the inner wall of part of the circular groove. Multiple external protruding teeth are evenly welded to the outer circumference of part of the small disc. A small gear is provided in the circular groove. The small gear meshes with multiple internal protruding teeth and multiple external protruding teeth in sequence. A linkage shaft is horizontally welded to the center of the small gear. An L-shaped support plate is welded to the bottom of the worktable. The linkage shaft passes through the L-shaped support plate and is rotatably connected to it. One end of the first lead screw extends out of the first slot. A belt connects the linkage shaft and the first lead screw.

[0012] The forward and reverse motors are started, causing the turntable to rotate forward. Multiple ratchet teeth on the outer circumference of the turntable mesh with the first driven gear, causing it to rotate. The first driven gear then drives the drive shaft to rotate. The drive shaft, through a drive bevel gear and a driven bevel gear, drives the driven shaft to rotate. The driven shaft drives the large disc to rotate, which in turn drives the small disc to rotate. Multiple internal protruding teeth on the inner wall of the circular groove mesh with the pinion, causing it to rotate forward. The pinion drives the linkage shaft to rotate forward, which, through a belt, drives the first lead screw to rotate forward. This causes two moving blocks to move towards each other on the first lead screw. The two moving blocks then drive two clamping plates to move towards each other until they clamp the elevator rail. At this point, the multiple internal protruding teeth and the pinion are fully engaged, and the forward and reverse motors are turned off. After one drilling operation, the forward and reverse motors are restarted to drive the turntable forward and backward. As the turntable rotates, multiple ratchet teeth on its outer circumference continue to mesh with the first driven gear, causing it to rotate. Then, multiple protruding teeth on the outer circumference of the small disc mesh with the pinion, causing it to rotate in the opposite direction. Similarly, this causes the two clamping plates to move in opposite directions, releasing their grip on the elevator track. The ratchet teeth on the outer circumference of the turntable then mesh with the second driven gear, causing it to rotate. The second driven gear then rotates the second lead screw, causing the moving plate to move forward on the second lead screw. The moving plate, through the L-shaped connecting plate, causes the push plate to move forward, releasing the fixed elevator track and pushing it forward a distance to the next drilling position. Repeating this operation completes continuous drilling on the elevator track. This continuous drilling process requires no manual operation, has a higher degree of automation, is simpler to operate, and improves work efficiency.

[0013] The beneficial effects of this utility model are: it can complete continuous drilling operations on elevator tracks, the continuous drilling process does not require manual operation, has a higher degree of automation, is easier to operate, and improves work efficiency; moreover, the fixing, loosening and forward conveying of elevator tracks are completed by only one drive device and mechanism, which has stronger linkage and lower equipment cost.
