Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a switch machine technical field, especially a kind of switch machine contact monitoring equipment and switch machine. BACKGROUND
[0002] Switch machine is the important signal basic equipment for reliably switching turnout position, changing turnout opening direction, locking turnout point rail, reflecting turnout position, which can ensure driving safety, improve transport efficiency and improve the labor intensity of driving personnel.
[0003] Train drives to different destination according to different track direction, and the driving track direction is changed by controlling switch machine to operate turnout position (positioning or reverse position), to change train driving line.
[0004] For switch machine, internal contact point (mainly including moving contact group and static contact group) is the key equipment for signal state transmission between internal and external interlocking system of switch machine, and its specific role is: moving contact group and static contact group are connected and disconnected according to certain rule, so that different loops of turnout control system are connected, and then the indicating circuit for reflecting turnout positioning state or the indicating circuit for reflecting turnout reverse position state is turned on.
[0005] It should be noted that when switch machine is in place, moving contact (specifically moving contact ring on moving contact) in moving and static contact group is embedded (i.e. inserted) into static contact (specifically static contact piece, similar to Y-shaped, inserted into the opening part of Y-shaped static contact piece) in static contact group, so as to connect indicating circuit.
[0006] After long-term use, switch machine will produce wear and tear, and phenomena such as insufficient contact depth or excessive contact depth will occur, which will cause poor contact between moving contact and static contact, and cannot form indicating circuit, so as to judge current turnout state.
[0007] According to requirements, the contact depth of moving contact in static contact should not be too shallow (for example, according to relevant standard requirements, it should not be less than 4mm), and the gap between moving contact and static contact seat should not be less than the width required in advance (for example, not less than 3mm). These requirements are to ensure the normal operation of switch machine and the reliability of contact point;
[0008] In actual application, the contact depth of contact point should not be too deep, because too deep contact may cause fatigue force failure of static contact piece, and even cause static contact piece to break. Insufficient contact depth of contact point will cause switch machine to lose table, and cannot form indicating circuit and other faults.
[0009] Therefore, it is necessary for the station maintenance personnel to regularly check the contact state of the switch machine, and timely adjust the contact depth of the movable contact in the static contact to ensure that the contact depth of the movable contact in the static contact is within the standard requirement.
[0010] Since the contact is installed in the switch machine and in a closed state, the current maintenance method for the switch machine contact mainly adopts the method of regularly going on the track to check and judge each switch machine, and the contact state of the switch machine cannot be known in time during the non-tracked period, so that the fault state of the contact is not judged in time. At the same time, regular maintenance of each switch machine on the track requires a large amount of manpower and material resources.

[0070] Referring to Figure 1 , Figures 2a to 2c , Figures 3 to 13 The present application provides a kind of monitoring equipment of switch machine contact point, comprising: loader cover 101, image acquisition module and protective cover 301;
[0071] The upper surface of loader cover 101 is provided with hollow back-shaped boss 1016 (the upper and lower ends of back-shaped boss 1016 are both open openings);
[0072] The top of back-shaped boss 1016 is sealingly provided with protective cover 301;
[0073] Between the U-shaped boss 1016 and the protective cover 301, a receiving cavity is formed for placing the image acquisition module;
[0074] An image acquisition module is installed inside the cavity;
[0075] The image acquisition module is fixedly connected to the loader cover 101;
[0076] The image acquisition module is located directly above the original contact seat 500 inside the main housing 400 of the switch machine;
[0077] The image acquisition module is used to acquire video images from the contact base 500 and the moving and stationary contacts on the top of the contact base.
[0078] In this utility model, for specific implementation, see [link to relevant documentation]. Figure 1 , Figures 2a to 2c On the loader cover 101, there are two elongated holes 1011 that are vertically and symmetrically distributed front and back;
[0079] Two elongated holes 1011 are located directly above the front and rear ends of the original contact seat 500 inside the main housing 400 of the switch machine;
[0080] Two elongated holes 1011 are set to correspond to the two camera modules 202 in the image acquisition module;
[0081] It should be noted that the two camera modules 202 in the image acquisition module are located above the two elongated holes 1011. The elongated holes 1011 are used to expose the cameras of the camera modules 202, so that the cameras can acquire video images of the contact base 500 below and the moving and stationary contacts on the top of the contact base 500.
[0082] It should be noted that, for this utility model, the design of two symmetrical elongated holes 1011 facilitates the camera module 202 in the image acquisition module to take pictures, and increases the ambient lighting of the dynamic and static contacts on the top of the contact base 500.
[0083] For specific implementation details, see [link to implementation details]. Figure 12 As shown, the top front and rear ends of the contact base 500 are provided with a moving contact group 501 and two stationary contact groups 502. The moving contact group 501 is located between two adjacent stationary contact groups 502, and the two stationary contact groups 502 are symmetrically distributed with the moving contact group 501 as the center.
[0084] Each moving contact group 501 includes three moving contacts that are equally spaced laterally, and each moving contact is provided with a moving contact ring 5010 at the top.
[0085] Each stationary contact group 502 includes three stationary contact pieces 5020 (i.e., serving as stationary contacts) distributed laterally at equal intervals.
[0086] It should be noted that the static contact point piece 5020 is similar to Y-shaped, and the movable contact ring is inserted into the opening of the Y-shaped static contact point piece to realize the contact between the movable contact and the static contact.
[0087] It should be noted that through the action of the movable contact group and the static contact group, the position of the switch rail can be timely and correctly reflected, and the functions of control and indication can be completed. When the switch machine is working, the motor rotates to drive the friction connector of the speed reducer to act, and the ball screw rotates to drive the push plate sleeve to move the action plate. When the starting piece is lifted, the movable contact group is switched from the position in contact with one side of the static contact group to the non-contact position in the middle, the original indicating circuit is disconnected, the action circuit is connected, the locking mechanism is unlocked, the action rod moves, and the switch is switched to the locked switch. When the starting piece falls and the indicating rod is in the correct position, the movable contact group is switched from the non-contact position in the middle to the position in contact with the other side of the static contact group, at which time the action circuit is disconnected and the indicating circuit is connected. The structure design and working principle of the movable contact group and the static contact group on the switch machine are known mature technology, and will not be described here.
