A laser vertical plummet

Abstract

The present invention provides a laser vertical plummet device, which comprises a top cover housing, a pendulum retaining spring, a pendulum bearing, a swing seat, a pendulum, a laser, and a bottom cover. The present invention utilizes a pendulum combined with high-frequency vibration to achieve rapid and stable vertical downward laser emission. The pendulum is machined using numerical control technology and has a 6mm diameter center hole for mounting the laser. A 2mm diameter laser emission channel is provided below the laser. The pendulum is made of high-density H62 brass to achieve a plumb effect. Furthermore, the pendulum is structurally designed to be smaller at the top and larger at the bottom to emphasize plumbness. The bearing's swing has been further optimized by adding a high-frequency eccentric vibrator to the bearing end. Through the dual effects of lubricant and bidirectional high-frequency vibration, plumbness is further ensured. Furthermore, an unlocking pin and a stop ring are used to flexibly release the copper pendulum. An elastic rubber ring is used to increase friction with the guide rail's centering hole, achieving a tight fit.

Description

Technical Field

[0001] The invention relates to a laser plummet, in particular to a laser vertical plummet. Background Art

[0002] Some vehicles need to accurately align with points on the ground during operation. The current use of traditional plumb bobs for alignment has the following shortcomings: First, many people are involved in the alignment operation, and four operators are required: a commander, a driver, one on the vehicle, and an observer; second, the alignment time is long, and the process is: after the vehicle is started, the commander driver drives along the guide line to the point to be aligned. During driving, the person on the vehicle lowers the plumb bob, and the observer is responsible for holding the plumb bob. When the plumb bob is vertically aligned with this point, he blows a whistle. After hearing the whistle, the commander commands the vehicle to stop; third, the observer needs to hold the plumb bob by hand while the vehicle is driving, which is somewhat dangerous; fourth, the plumb bob often swings widely while the vehicle is driving, affecting the accuracy of alignment.

[0003] Currently, laser plumb bobs are also used for corresponding operations. However, the shortcomings of this technology are as follows: first, the correction of the verticality of the light beam is done manually; second, due to different application areas, laser plumb bobs are used for engineering measurements on the ground, underground, in light and no light conditions, and cannot meet the special use needs of special fields. Summary of the Invention

[0004] This invention aims to create a laser vertical plummet device that allows a vehicle to position itself vertically at a fixed point on the ground. This device replaces the traditional plumb bob. Before entering the plummet area, it is snapped onto the centering hole of the guide rail. This snapping releases the swing limiter, and when the switch is turned on, the laser beam is directed downward in a stable vertical direction. This improves the stability of the laser's vertical downward direction while reducing the number of operators (onboard personnel), eliminating the safety risk of the observer.

[0005] The present invention provides a laser vertical plummet device, which includes a top cover, a housing, a pendulum retaining spring, a pendulum bearing, a swing seat, a pendulum, a laser and a bottom cover, wherein:

[0006] The shell is provided with a partition and divides the shell into an upper chamber and a lower chamber. The inner side of the upper portion of the upper chamber is provided with a thread, which is matched with the thread on the outer side of the lower portion of the top cover. The inner side of the lower portion of the lower chamber is provided with a thread, which is matched with the thread on the outer side of the upper portion of the lower end cover. A circular hole is provided at the center of the partition, and a thread is provided inside the circular hole, which is matched with the external thread on the lower portion of the swing seat.

[0007] The pendulum is mounted on the swing seat through the pendulum retaining spring and the pendulum bearing to achieve swing. The pendulum is provided with a central hole for mounting the laser.

[0008] A circular opening is provided in the center of the bottom of the lower end cover in cooperation with the bottom of the pendulum, and a bulge is formed downwards, and a sealing cover is installed at the bulge.

[0009] Furthermore, it also includes a high-frequency oscillator, which is installed in the upper cavity of the shell.

[0010] Furthermore, it also includes a battery box, which is installed in the top cover to supply power to the high-frequency oscillator and the laser.

[0011] Furthermore, it also includes an over-swing anti-collision ring, which is installed in the lower cavity of the shell and is used to prevent the pendulum from colliding with the shell.

[0012] Furthermore, the lower end cover is provided with an unlocking striker for unlocking and / or locking the pendulum from swinging.

[0013] Furthermore, an elastic rubber ring is provided at the central protrusion of the lower part of the lower end cover.

[0014] This invention uses a pendulum combined with high-frequency vibration to achieve fast, stable, vertical downward laser projection. The pendulum is CNC-machined and features a 6mm diameter hole in the center for mounting the laser. A 2mm diameter laser emission channel is located below the laser. The pendulum is made of high-density H62 brass to achieve a plumb effect. Furthermore, the pendulum is structurally designed to be smaller at the top and larger at the bottom to emphasize plumbness. To prevent the pendulum from swinging, a spherical joint bearing is used, utilizing friction within the bearing to provide damping. After numerous tests and repeated selections, the SKF GE5E spherical joint bearing was chosen. Made of highly hard carburized bearing steel, it is a radial spherical plain bearing. Its main advantage is uniform friction in all directions, preventing stalling (not reaching the vertical position). Furthermore, the bearing's swing has been optimized by adding a high-frequency eccentric vibrator to the bearing end. Through the dual effects of lubricant and bidirectional high-frequency vibration, verticality is further ensured. At the same time, the unlocking pin and the anti-swing ring are used to flexibly release the copper pendulum, and the elastic rubber ring is used to increase the friction force with the center hole of the guide rail to achieve a tight fit.
