Abstract
Description
Technical Field
[0001] This utility model relates to a rail transit vehicle detection device, and more particularly to a rail transit vehicle relocation platform over-limit detection device. Background Technology
[0002] The transfer platform is an essential piece of equipment in the production of rail transit vehicles. It is primarily used for track changing and track switching operations, facilitating manufacturing, assembly, and testing of rail transit vehicles at different workstations. Before formal assembly, rail transit vehicles are supported by dummy trolleys. Due to differences in manufacturing and maintenance processes, and variations in the processes for level three, four, and five maintenance, different dummy trolleys are required to meet process requirements. Inconsistent disassembly levels on the roofs of the maintenance vehicles result in variations in their final heights. This has led to several accidents during actual production where rail transit vehicles collided with factory gates. Furthermore, during the vehicle adjustment and pulling process, inadequate operator observation can cause collisions between the rail transit vehicles on the transfer platform and adjacent contact line pillars, posing significant safety hazards. Utility Model Content
[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an automatic detection device for over-limit issues in rail transit vehicles during vehicle relocation.

Several mounting plates are symmetrically arranged on the left and right columns, and photoelectric sensors are mounted on the mounting plates. The photoelectric sensors are connected to an alarm. The photoelectric sensors are divided into two groups: when installed in the lower middle part of the gantry frame, they are used to detect whether a vehicle exceeds the safe relocation range; when installed in the upper part of the gantry frame, they are used to detect whether a railway vehicle exceeds the height limit.
[0006] According to some embodiments of this utility model, the photoelectric sensor consists of a light transmitter and a light receiver, and the light transmitter and the light receiver are symmetrically arranged on the left and right columns, respectively.

[0024] Reference Figure 1 , Figure 2 A vehicle relocation platform over-limit detection device includes a gantry frame 1, which consists of left and right columns 11 and crossbeams 12 mounted on the upper ends of the left and right columns 11. Several mounting plates 2 are symmetrically arranged on the left and right columns 11, and photoelectric sensors 3 are mounted on the mounting plates 2. The photoelectric sensors 3 are connected to an alarm 4. Depending on functional requirements, photoelectric sensors 3 can be installed at different positions on the gantry frame 1. When the photoelectric sensors 3 are installed in the lower middle part of the gantry frame 1, they can detect whether railway vehicles exceed the safe relocation range during the operation of the vehicle relocation platform 6. When the photoelectric sensors are installed in the upper part of the gantry frame 1, they can detect whether railway vehicles exceed the height limit when passing through the gantry frame 1, allowing operators to quickly determine whether railway vehicles exceed the factory's height restrictions.
[0025] The photoelectric sensor 3 is a through-beam type, consisting of a projector 31 and a receiver 32, which are symmetrically arranged on the left and right columns 11, respectively. When a foreign object blocks the infrared light from the projector, an audible and visual alarm signal will be triggered, thereby alerting the operator and improving the safety of shunting operations in the rail transit industry.
[0026] The alarm 4 is an audible and visual alarm. It can effectively remind operators in real time that the railway vehicles being transported are oversized. The audible and visual alarm will continuously broadcast voice reminders until the operator eliminates the hazard. For ease of installation, the alarm 4 is fixed to the left and right columns 11 with bolts.
[0027] The gantry frame 1 allows for adjustment of the installation height and position of the mounting plate 2 as needed. The mounting plate 2 is installed on the left and right columns 11 using positioning screws 5. Depending on actual requirements, the mounting plate 2 can be installed at any height on the left and right columns 11. The mounting plate 2 has horizontally arranged through holes 23 through which the positioning screws 5 pass, allowing for adjustment of the distance between the mounting plate 2 and the left and right columns 11.
[0028] In addition, the mounting plate 2 is provided with a longitudinally arranged strip-shaped hole 21, and the photoelectric sensor 3 is mounted on the strip-shaped hole 21 by a positioning screw 22. The vertical height of the photoelectric sensor 3 can be controlled through the strip-shaped hole 21.
[0029] Reference Figure 3 The left and right uprights 11 are each provided with a mounting base 13 at their bottom. The mounting base 13 is an L-shaped plate used for fixed installation on both sides of the vehicle transfer platform 6. The gantry frame 1 is located at the left and right ends of the vehicle transfer platform 6. The installation position is determined by the length detection of the working condition, and the height of the gantry frame 1 is specifically considered based on the height of the vehicle being detected.
[0030] In actual use, based on the maximum length of the railway vehicle, two sets of gantry frames 1 are welded to the left and right ends of the transfer platform 6 respectively. Three sets of photoelectric sensors 3 are installed on the middle and lower parts of the two sets of gantry frames 1 through mounting plates 2 to detect whether the railway vehicle is parked within the safe range of the transfer platform. Based on the maximum height limit of the factory gate, a set of photoelectric sensors 3 are installed on the top of the gantry frame 1 through mounting plates 2 to detect whether the railway vehicle exceeds the height limit of the factory gate.
[0031] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
