Description

Technical Field

[0001] This utility model relates to the field of elevator traction machine technology, specifically to an elevator traction machine that is easy to position and install. Background Technology

[0002] Currently, when installing elevator traction machines, the base plate of the traction machine needs to be placed according to the drawings, and then the traction machine is slowly fixed in place. During installation, the position of the traction machine needs to be frequently calibrated, and the position of the traction steel rope on the traction machine must be ensured to be aligned. However, during the current traction machine installation process, many elevator shafts are poorly lit. While tightening the bolts to fix the traction machine, slight wobbling can easily occur after alignment, leading to misalignment between the traction machine and the guide rails. Such slight misalignment is difficult for workers to detect, causing problems during subsequent testing and requiring reinstallation. This increases the debugging time and reduces installation efficiency. Utility Model Content

[0003] The purpose of this utility model is to solve the problem that during the process of continuously tightening bolts to fix the traction machine, the aligned traction machine is prone to slight wobbling, which leads to a deviation in the alignment of the traction machine and the guide rail. Such slight deviations are not easy for staff to detect, thus causing problems in subsequent testing and increasing the debugging time. This utility model provides an elevator traction machine that is easy to position and install.

[0004] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0005] An elevator traction machine that is easy to position and install includes a traction machine body. A mounting base plate is provided on the lower side of the traction machine body, and a fixing hole is provided on the mounting base plate. A laser ranging mechanism is provided on one side of the mounting base plate located at the fixing hole, and the laser ranging mechanism is flush with the side of the fixing hole. A light emitting mechanism is provided at the center position of one side of the traction machine body, and a reflective centering mechanism is provided on one side of the light emitting mechanism.

[0006] Preferably, the light emitting mechanism includes a U-shaped plate, one side of which is fixedly mounted on the traction machine body, and positioning plates are fixedly mounted on both end sidewalls of the U-shaped plate. Positioning screw holes are provided on the sidewalls of the positioning plates, and positioning slots are symmetrically provided on the sidewalls of the traction machine body. The positioning screw holes and positioning slots are matched and provided with connecting bolts. A laser emitter is provided on the middle sidewall of the U-shaped plate.

[0007] Preferably, the U-shaped plate has an assembly screw hole on its middle side wall, the laser emitter has an external thread on its side wall, and the laser emitter is screwed into the assembly screw hole. A limit plate is fixedly installed on the side wall of the laser emitter.

[0008] Preferably, the reflective centering mechanism includes two support plates, which are symmetrically mounted on the side walls of the U-shaped plate. An adjusting shaft is rotatably mounted on the side walls of both support plates. A reflector is fixedly mounted on one end of each adjusting shaft, and the reflector is aligned with the laser emitter. A damping tube is slidably sleeved on the side walls of each adjusting shaft, and one end of each damping tube is fixedly mounted on the two support plates.

[0009] Preferably, the laser ranging mechanism includes four L-shaped blocks, one end of each of the four L-shaped blocks is fixedly mounted on the side wall of the mounting base plate, and a laser rangefinder is snapped between the four L-shaped blocks. The light source emitting end of the laser rangefinder is flush with the edge of the fixing hole. Each of the four L-shaped blocks has an insertion groove, and a connecting rod is inserted into the insertion groove. One end of each of the four connecting rods is fixedly mounted with a pressure plate.

[0010] Preferably, an observation port is provided on the side wall of the pressure plate, and limit screw holes are provided on the side walls of the connecting rod and the L-shaped block, and limit bolts are screwed into the limit screw holes.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. In this utility model, by using components such as a laser emitter, a reflector, and a laser rangefinder, during the alignment and installation of the traction machine body, the laser emitter is activated, causing the reflector to reflect the beam onto a designated reference object. Thus, when the bolts on the mounting plate are tightened to fix the traction machine, if the alignment of the traction machine deviates, the generated beam will also shift on the reference object, making it easier for workers to detect and adjust in a timely manner. Furthermore, the laser rangefinder can observe changes in the distance between the mounting plate and both sides, reducing the probability of detecting errors during post-installation testing. This saves rework time and reduces subsequent debugging time, facilitating the installation of the traction machine. Attached Figure Description

[0022] like Figure 1-4 As shown, an elevator traction machine that is easy to position and install includes a traction machine body 1. A mounting base plate 5 is provided on the lower side of the traction machine body 1, and a fixing hole 6 is provided on the mounting base plate 5. A laser ranging mechanism 4 is provided on one side of the mounting base plate 5 at the fixing hole 6, and the laser ranging mechanism 4 is flush with the side edge of the fixing hole 6. The laser ranging mechanism 4 includes four L-shaped blocks 401. One end of each of the four L-shaped blocks 401 is fixedly installed on the side wall of the mounting base plate 5, and a laser rangefinder 403 is snapped between the four L-shaped blocks 401. The light source emitting end of the laser rangefinder 403 is flush with the edge of the fixing hole 6. With the help of the laser rangefinder 403, the distance of the side offset can be accurately determined, thereby facilitating the adjustment and repositioning of the mounting base plate 5.

[0023] Each of the four L-shaped blocks 401 has a slot 407 on its side wall, and a connecting rod 402 is inserted into the slot 407. A pressure plate 404 is fixedly installed at one end of each of the four connecting rods 402. An observation port is provided on the side wall of the pressure plate 404. Limiting screw holes 405 are provided on the side walls of both the connecting rods 402 and the L-shaped blocks 401, and limiting bolts 406 are screwed into the limiting screw holes 405. With the help of the pressure plate 404 and the connecting rods 402, the laser rangefinder 403 can be pressed and fixed, ensuring its good stability.

[0024] A light emitting mechanism 2 is provided at the center of one side of the traction machine body 1. The light emitting mechanism 2 includes a U-shaped plate 201. One side of the U-shaped plate 201 is fixedly installed on the traction machine body 1, and positioning plates 202 are fixedly installed on the side walls of both ends of the U-shaped plate 201. Positioning screw holes 203 are provided on the side walls of the positioning plates 202. Positioning slots are symmetrically provided on the side walls of the traction machine body 1. The positioning screw holes 203 are matched with the positioning slots, and connecting bolts are provided in the positioning screw holes 203 and the positioning slots. The positioning slots are located on both sides of the center line of the traction machine body 1, so as to facilitate the alignment of the center line of the U-shaped plate 201 with the center line of the traction machine body 1.

[0025] A laser emitter 205 is provided on the middle side wall of the U-shaped plate 201. An assembly screw hole 204 is provided on the middle side wall of the U-shaped plate 201. An external thread is provided on the side wall of the laser emitter 205, and the laser emitter 205 is screwed into the assembly screw hole 204. A limit plate 206 is fixedly installed on the side wall of the laser emitter 205. The limit plate 206 can lock the laser emitter 205 after screwing, thereby improving its stability. The screwed installation can facilitate the disassembly and maintenance of the laser emitter 205.

[0026] A reflective alignment mechanism 3 is provided on one side of the light emitting mechanism 2. The reflective alignment mechanism 3 includes two support plates 301, which are symmetrically mounted on the side walls of the U-shaped plate 201. An adjusting shaft 303 is rotatably mounted on the side walls of both support plates 301. A reflector 304 is fixedly mounted at one end of each adjusting shaft 303. The adjusting shafts 303 can rotate the reflector 304, facilitating the reflected light to find a suitable reference object. The reflector 304 is aligned with the laser emitter 205. A damping tube 302 is slidably fitted on the side walls of both adjusting shafts 303, and one end of each damping tube 302 is fixedly mounted on the two support plates 301. The damping tubes 302 restrict the rotation of the adjusting shafts 303, thereby ensuring the stability of the reflector 304.

[0027] In summary: During the alignment and installation of the traction machine body 1, the laser emitter 205, which is positioned aligned with the centerline of the traction machine body 1, is activated. This causes the reflector 304 to reflect the laser beam generated by the laser emitter 205 onto a designated reference object. The user can then rotate the adjustable shaft 303 to rotate and adjust the reflector 304 to select the reference object. When the traction machine is fixed by continuously tightening the bolts located in the fixing holes 6 on the mounting base plate 5, if the centering of the traction machine deviates, the generated beam will also deviate on the reference object, making it easier for the staff to detect and adjust in time. Moreover, the laser rangefinder 403 can observe the changes in distance between the mounting base plate 5 and the fixing holes 6 and the two sides, thereby reducing the probability of detecting errors during the testing process after the traction machine is installed. After the installation is completed, by removing the limit bolts 406, the connecting rod 402 and the pressure plate 404 can be removed, and then the laser rangefinder 403 can be removed. Then, the connecting bolts between the positioning plate 202 and the traction machine body 1 can be loosened, so that the U-shaped plate 201 and its components can be removed and reused for the installation of other traction machines.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
