Description

Technical Field

[0001] The present invention relates to a detection device for rail transit vehicles, and particularly to an over-limit detection device for a rail transit vehicle transfer platform. Background Art

[0002] The transfer platform is an essential and important process equipment in the production process of rail transit vehicles, mainly used for the operation of changing tracks and transferring lines of rail transit vehicles, so as to carry out operations such as manufacturing, assembling, and detecting rail transit vehicles at different workstations. Before the formal assembly of rail transit vehicles is completed, the false platform is responsible for supporting the rail transit vehicles. Since the new manufacturing and overhaul processes are different, and the processes for the third, fourth, and fifth-level overhauls are also different, different false platforms need to be selected to meet the process requirements. The disassembly degrees of the roofs of the overhauled rail transit vehicles are inconsistent, resulting in different final heights of the rail transit vehicles. In the actual production process, there have been multiple accidents where rail transit vehicles collided with the factory building gates. During the process of pulling and adjusting rail transit vehicles, due to the inattentiveness of the operators, collisions between the rail transit vehicles on the transfer platform and the adjacent trolley wire columns have also occurred, posing a great potential safety hazard.

If there is a description of the first and the second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features or implicitly specifying the sequence relationship of the indicated technical features.

[0023] In the description of the present invention, unless otherwise clearly defined, words such as "arrangement", "installation", "connection", etc. should be understood in a broad sense. Those skilled in the relevant technical field can reasonably determine the specific meanings of the above words in the present invention in combination with the specific content of the technical solution.

[0024] Refer to Figure 1 、 Figure 2 , a detection device for over-limit of a car transfer table, which includes a gantry 1. The gantry 1 is composed of left and right columns 11 and a cross beam 12 arranged at the upper ends of the left and right columns 11. A plurality of mounting plates 2 are symmetrically arranged on the left and right columns 11. A photoelectric sensor 3 is arranged on the mounting plate 2, and the photoelectric sensor 3 is connected to an alarm 4. According to functional requirements, the photoelectric sensor 3 can be installed at different positions on the gantry 1. When the photoelectric sensor 3 is installed in the middle and lower part of the gantry 1, it can detect whether the railway vehicle exceeds the car transfer safety range when the car transfer table 6 is running; when the photoelectric sensor is installed in the upper part of the gantry 1, it can detect whether there is an over-height situation of the railway vehicle when the railway vehicle passes through the gantry 1, which is convenient for the operator to quickly judge whether the railway vehicle exceeds the height limit of the workshop.

[0025] The photoelectric sensor 3 is of the opposed type and is composed of a light emitter 31 and a light receiver 32. The light emitter 31 and the light receiver 32 are respectively symmetrically arranged on the left and right columns 11. When an object blocks the infrared ray of the light emitter, it will trigger the signal of the sound and light alarm, so as to remind the operator and improve the safety of the car pulling operation in the rail transit industry.

[0026] The alarm 4 is a sound and light alarm. It can effectively remind the operator in real time that the railway vehicle being transported has an over-limit situation. Before the operator eliminates the hidden danger, the sound and light alarm will continuously give voice broadcast reminders. For the convenience of installation, the alarm 4 is fixed on the left and right columns 11 by bolts.

[0027] The gantry 1 can adjust 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 through positioning screws 5. According to actual needs, the mounting plate 2 can be installed at any height of the left and right columns 11. A through hole 23 is transversely arranged on the mounting plate 2. The positioning screw 5 passes through the through hole 23 and is installed on the left and right columns 11. The distance between the mounting plate 2 and the left and right columns 11 can be controlled and adjusted through the through hole 23.

[0028] In addition, a strip hole 21 is longitudinally arranged on the mounting plate 2. The photoelectric sensor 3 is installed on the strip hole 21 through a positioning screw 22. The vertical height of the photoelectric sensor 3 can be controlled through the strip hole 21.

[0029] Refer to Figure 3 , mounting bases 13 are respectively arranged at the bottoms of the left and right columns 11. The mounting base 13 is an L-shaped plate and is used for fixedly installing on both side faces of the car transfer table 6. The gantry 1 is respectively located at the left and right ends of the car transfer table 6. The installation position is determined by the length detection of the working condition, and the height of the gantry 1 is specifically considered according to the height of the detected vehicle.

[0030] In actual use, according to the maximum length of the railway vehicle, two groups of gantries 1 are respectively welded to the left and right ends of the car transfer table 6. Three groups of photoelectric sensors 3 are respectively installed through the mounting plate 2 in the middle and lower parts of the two groups of gantries 1 to respectively detect whether the railway vehicle is parked within the safe range of the car transfer table; according to the maximum restricted height of the factory building door, a group of photoelectric sensors 3 are respectively installed through the mounting plate 2 at the top position of the gantry 1, which can detect whether the railway vehicle exceeds the restricted height of the factory building door.

[0031] The preferred specific embodiments of the present invention have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations according to the concept of the present invention without creative labor. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field of the present invention based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the protection scope determined by the claims.
