Description

Technical Field

[0001] The utility model relates to the technical field of visual blind spot detection tools, in particular to a switch machine notch inspection tool. Background Art

[0002] Whether the turnout switching equipment can work properly directly affects whether the railway transportation can be carried out efficiently, orderly and safely, and whether the switch machine can work properly is an important prerequisite for ensuring the safety and stability of the turnout and the safe and stable operation of the train. At present, due to the high failure rate of the switch machine gap, it is usually necessary to convert the detection of the degree of closeness of the turnout point rail into the measurement of the corresponding gap size inside the switch machine. Therefore, a switch machine gap detection system is developed and designed to detect the size of the switch machine gap, so as to issue an early warning based on the value of the gap. At present, the methods for detecting the switch machine gap mainly include contact conductive contact sensor detection method, non-contact magnetoelectric sensor detection method, photoelectric detection method and image processing-based detection method.

[0003] Disadvantages of existing technology:

[0004] 1) Using a conductive contact sensor to monitor the switch gap cannot obtain an accurate gap size value. It is not only easily affected by vibration, rainwater penetration, rust and failure, resulting in false alarms and missed alarms, but also has a high failure rate or induces an increase in the failure rate of the switch.

[0005] 2) Observe with the naked eye based on experience. This method has high requirements for maintenance workers. The switch gap standard is 1.5±0.5mm. For gaps of millimeters, it is easy to have large errors when observing with the naked eye.

[0006] 3) Use 1.6mm iron wire to insert into the gap for inspection. During the use of the iron wire, there will be certain errors in the accuracy of the iron wire inspection results due to factors such as equipment and line of sight obstruction, insertion direction, diameter of the iron wire and low strength of the iron wire.

[0007] In summary, a switch gap inspection tool is urgently needed to solve the problems existing in the prior art. Utility Model Content

[0025] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0026] Example:

[0027] See also Figure 1 This embodiment discloses a switch machine gap inspection tool, comprising:

[0028] The movable part includes a hand-held rod 1, a universal hose 2 and a first connecting piece, wherein both ends of the hand-held rod 1 are respectively connected to a universal hose 2, and the end of the universal hose 2 away from the hand-held rod 1 is connected to the first connecting piece;

[0029] Two measuring parts are respectively arranged at both ends of the movable part, and the measuring parts include a measuring rod 3 and a second connecting member arranged at one end of the measuring rod 3, and the second connecting member is detachably connected to the first connecting member.

[0030] The switch gap inspection tool disclosed in this embodiment bypasses the internal structure of the switch machine through the universal hose 2, so that the measuring rod 3 can reach the switch gap for measurement. This embodiment has a simple structure and is easy to operate. It can save auxiliary measures and consumables, reduce the number of construction personnel, reduce installation difficulty, and improve installation and construction efficiency, thereby achieving the effects of speeding up, reducing costs, increasing efficiency, and ensuring safe construction.

[0031] Preferably, the first connecting member is a nut, and the second connecting member is a threaded interface matching the nut. The measuring part in this embodiment is detachably designed through the nut and the threaded interface matching the nut, and can be applied to the internal notch inspection of various types of switch machines in rail transit. In addition, this embodiment can also adopt a variety of detachable connection structures to realize the installation of the measuring part, such as a snap-on structure.

[0032] Preferably, the measuring rod 3 is provided with a microprobe and an infrared ranging sensor. In this embodiment, the distance between the measuring rods 3 is detected by the infrared ranging sensor, and the size of the switch gap can be obtained by adding the diameter of the two measuring rods 3. In addition, in this embodiment, a microprobe is installed at the front end of the measuring rod 3, and the internal structure of the switch is observed through the microprobe, so that the measuring rod 3 can avoid obstruction and enter the switch gap for measurement.

[0033] Preferably, a digital display is provided on the handheld rod 1 , and the digital display is connected to the microprobe and the infrared ranging sensor. In this embodiment, a digital display is provided on the handheld rod 1 , and the digital display in this embodiment is used to display the distance between the measuring rods 3 .

[0035] Preferably, the diameter range of the measuring rod 3 is 0.3mm-1.5mm. Since the standard of the switch gap is 1.5±0.5mm, the specification of the measuring rod 3 in this embodiment is 0.3mm-1.5mm. By replacing the measuring rods 3 with different diameters, this embodiment can accurately measure whether the switch gap meets the standard. Specifically, two measuring rods 3 with a diameter of 0.5mm are first used for measurement. If the two measuring rods 3 can be placed in the switch gap at the same time, it means that the size of the switch gap exceeds the minimum standard. Then two measuring rods 3 with a diameter of 1mm are used for measurement. If the two measuring rods 3 cannot be placed in the switch gap at the same time or are engaged in the switch gap, it means that the size of the switch gap is smaller than the highest standard.

[0036] Preferably, a protective layer is provided on the outside of the hand-held rod 1 and the universal hose 2. In this embodiment, the protective layer is preferably a rubber layer.

[0037] The switch machine gap inspection tool disclosed in this embodiment is used as follows:

It should be noted that in S1, the switch needs to be installed in advance, can be electrically operated, and has been debugged. The switch can be electrically or manually operated to lock at one end. During the switch gap adjustment process, the switch switch needs to be disconnected to ensure the safety of the construction process.

[0039] S2: Put the measuring part and the universal hose 2 into the switch machine. It should be noted that in S2, the universal hose 2 is adjusted to bend so as to avoid the internal structure of the switch machine and quickly check the size of the gap of the switch machine.
