Description

Technical Field

[0001] This invention relates to the field of rail transit vehicle technology, and in particular to a laser ink line positioning and detection auxiliary device for the installation of internal components during the production of rail transit vehicles, and a method of using the device. Background Technology

[0002] During the production of rail transit vehicles, the installation of interior components involves using a laser line gauge to locate the vehicle's centerline. The basic positioning process involves using previously installed positioning reference points a and b on the vehicle floor. (See [link to documentation]). Figure 1 As shown, each positioning reference point is composed of a positioning hole (201) and a positioning block (202). The positioning reference point is fixed inside the rail vehicle. A laser line is emitted by a laser ink line instrument so that the laser line passes through the center of the positioning hole (201) of positioning reference point b to the center of the positioning hole (201) of positioning reference point a. The straight line formed is used as a reference line for the interior components of the vehicle.

[0003] During the use of a laser line meter on a rail vehicle, one operator needs to place the laser line at a fixed position on the floor, turn on the laser line meter switch, and adjust the laser beam so that it penetrates the center of the positioning hole (201) on the positioning reference point b. Another operator, based on the position of the laser beam through the positioning reference point a on the positioning hole (201), controls the laser beams (103, 104, and 105) by verbally instructing them to adjust laser beam (105) to the left or laser beam (103) to the right. Upon receiving the instruction, the operator adjusts the laser line meter by adjusting the horizontal and rotational angles of the laser beams until the red laser emitted by the laser line meter completely penetrates the center of the positioning hole on both the reference positioning points a and b. Figure 1 Medium standard laser beam (104).

[0004] However, the existing adjustment methods require multiple adjustments to reach the positioning standard, and require the cooperation of two operators. Visual inspection is also necessary, resulting in low work efficiency, high labor intensity for operators, and high testing difficulty.

[0005] Therefore, based on the above-mentioned technical problems, those skilled in the art urgently need to develop a laser ink line instrument positioning and detection auxiliary device suitable for the installation of interior components during the production of rail transit vehicles, as well as a method for using the device. Summary of the Invention

[0006] The purpose of this invention is to provide an auxiliary device and method for positioning and detecting laser ink line instruments that improves the operation mode of laser ink line instrument positioning, addresses the problem of low efficiency in existing technologies that require two operators to work together in a communicative manner, and provides high operational stability, improved work efficiency, improved work quality, and simple and convenient operation.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The present invention provides a laser ink line meter positioning and detection auxiliary device, the auxiliary device comprising:

[0009] A laser ink line instrument positioned at positioning reference point b;

[0010] A laser reflecting device positioned at positioning reference point a, and a laser receiving device arranged coaxially with the laser ink line instrument on the laser ink line instrument;

[0011] The laser reflecting device has a cylindrical mirror body for reflecting the laser beam emitted by the laser ink line instrument, and the outer peripheral surface of the cylindrical mirror body is configured as a reflecting surface.

[0012] The laser receiving device includes:

[0013] Laser receiving sensor; and

[0014] Alarm components;

[0015] The laser receiving sensor is arranged in the same direction as the laser emitting end of the laser ink line instrument;

[0016] The alarm component includes an alarm indicator light and a buzzer;

[0017] When the laser receiving sensor receives the laser beam reflected by the laser reflecting device, the alarm indicator light illuminates.

[0018] When the laser receiving sensor fails to receive the laser beam reflected by the laser reflecting device, the buzzer sounds an alarm.

[0019] Furthermore, the laser reflection device includes:

[0020] The reflector's disc base;

[0021] The cylindrical mirror body fixed above the disc base of the reflecting device; and

[0022] A reference positioning cylinder and supporting feet are fixed below the reflector disc base. The reference positioning cylinder is fixed at the center position below the reflector disc base, and a plurality of supporting feet are evenly distributed around the bottom of the reflector disc base.

[0023] The cylindrical mirror is fixed at the center position above the disc base of the reflecting device, and the upper end of the cylindrical mirror has a groove, in which a level detector is installed.

[0024] The reference positioning cylinder can be embedded in the positioning hole of the positioning reference point a to maintain coaxiality with the positioning reference point a.

[0025] Furthermore, the laser receiving device includes:

[0026] Receiver disc base;

[0027] A cylinder fixed at the center position above the disk base of the receiving device; and

[0028] Circumferential positioning nesting feet fixed below the base of the receiving device disc;

[0029] The laser receiving device is fixed to the upper end of the laser ink line meter by the positioning nested foot, and the positioning nested foot contacts the outer peripheral surface of the upper end of the laser ink line meter;

[0030] The laser receiving sensor is arranged along the axial direction on the outer periphery of the cylinder.

[0031] The alarm component is integrated at the upper end of the cylinder.

[0032] Furthermore, the cylinder has a groove at the center of its upper end, and a level detector is embedded in the groove.

[0033] Furthermore, the upper end of the cylinder has a power switch.

[0034] The present invention also discloses a method for using a laser ink line meter positioning and detection auxiliary device, which is based on the laser ink line meter positioning and detection auxiliary device described above.

[0035] Furthermore, the method mainly includes the following steps:

[0036] S101. Position and fix the laser reflector at the positioning reference point a. The reference positioning cylinder of the laser reflector is embedded in the positioning hole of the positioning reference point a, so that the support foot of the laser reflector is in contact with the ground. Observe the level detection instrument on the cylindrical mirror of the laser reflector by adjusting the fine adjustment knob of the support foot to keep the laser reflector horizontal.

[0037] S102. Position and fix the laser line meter by positioning reference point b, and nest the laser receiving device above the laser line meter by positioning nesting feet on it, and keep the laser emitting end of the laser line meter and the laser receiving sensor of the laser receiving device in the same direction, and observe the level detector on the laser receiving device to ensure that the laser line meter and the laser receiving device are in a horizontal state, and turn on the laser line meter switch to project the laser beam onto the floor plane.

[0038] S103. Turn on the power switch of the laser receiver. If the laser beam emitted by the laser ink line instrument passes through the center line of positioning reference point a and positioning reference point b, the laser beam reflected back from the longitudinal arc surface of the cylindrical mirror of the laser reflector will be projected into the laser receiving sensor of the cylinder of the laser receiver, received by the receiver, and trigger the conduction of the circuit in the laser receiver, so that the alarm indicator light is lit. If the laser beam emitted by the laser ink line instrument cannot guarantee that it passes through the center of positioning reference point a and positioning reference point b at the same time, it will be reflected on the arc surface of the cylindrical mirror of the laser reflector. The laser receiver will not receive the reflected laser beam, triggering the buzzer alarm of the receiver.

[0039] S104. Adjust the laser line gauge by rotating the laser line gauge to adjust the angle of the emitted laser beam until the laser receiver receives the returned laser beam, until the circuit in the laser receiver is triggered to conduct, the alarm indicator light is lit, and the center line positioning work is completed.

[0040] The laser ink line meter positioning and detection auxiliary device and its usage method provided by the present invention have the following beneficial effects:

[0041] The auxiliary device and method of the present invention change the operation mode, changing the original operation mode of two operators cooperating and communicating with each other to the use of a laser receiving device and a laser reflecting device, thereby improving work efficiency, reducing the number of personnel required, and allowing one person to complete the positioning operation independently.
