Description

Beacon rotating device

Technical Field

The utility model relates to the field of subway operation safety, in particular to a beacon rotating device.

Background

The accurate positioning of the subway train is a key technology of a subway train operation control system, and is very important in a subway signal control system (ATP/ATO (Automatic Train Protection, automatic train protection subsystem; automatic Train Operation, automatic train operation system)). The train position information is accurately, timely and reliably acquired, so that the subway train position information is a guarantee of safe and effective operation of the subway, and is a premise of playing efficiency and improving operation performance.

Beacons are used as part of a subway signal control system for transmitting reliable ground information to a train on the ground. Beacons are divided into two types, one is a transponder (Balise) and the other is an electronic tag (RFID, radio Frequency Identification, radio frequency identification). Transponders are divided into passive (fixed information) and active (variable information) types. The passive (fixed information) transponder itself has no power supply, is a maintenance-free seal element, is convenient to install, and can be reprogrammed. Active (variable information) transponders have an independent power supply and standardized interfaces. The principle of beacon positioning is divided into passive beacon positioning and active beacon positioning, and passive beacon positioning needs to continuously identify two beacons so as to know the train running position and direction. Active beacon positioning can learn the train running position and direction information only by identifying one beacon.

At present, the existing railway beacon devices are all fixed, and no mobile beacon is found in investigation. The fixed beacon is fixed in the middle of the track through support mounting, the mounting support of the beacon is slightly different from a ballast bed according to the ballast bed, the integral support is adopted under the condition of the integral ballast bed, and the anchor ear and the sleeper can be locked and fixed under the condition of the ballast bed. Its advantages are stable and reliable structure and simple and convenient installation. But has the disadvantage of being relatively immovable and limited in use in some applications where beacon movement is required.

When a subway enters a maintenance warehouse, a beacon is required to be used for positioning the parking of the subway vehicle. The trench in the overhaul warehouse is used as an overhaul channel, and equipment or personnel are required to pass through the overhaul channel. If a fixed beacon is installed in a trench, insufficient space is available in the trench for equipment or personnel to pass through, which affects maintenance efficiency.

As shown in fig. 1 to 3, a beacon rotation device 100 according to an embodiment of the present utility model includes a cantilever 2, a first rotation shaft 3, a fixed bracket 14, and a rotation driving mechanism.

The two cantilevers 2 are arranged side by side. The beacon module 1 is mounted at one end of two cantilevers 2. The other ends of the two cantilevers 2 are connected with the two ends of the first rotating shaft 3 through shaft end connecting seats, so that the beacon module 1, the cantilevers 2 and the first rotating shaft 3 are connected into an integral positioning module.

As shown in fig. 3 and 4, the fixing bracket 14 is mounted to the trench 300 near the side wall or below the rail 200 by means including but not limited to bolting, welding or embedding.

The fixed bracket 14 has two vertical columns, two first bearing seats 4 can be installed at the top of the vertical columns, and the first rotating shaft 3 is assembled in the first bearing seats 4, so that the first rotating shaft 3 can rotate relative to the vertical columns through the first bearing seats 4, and further the cantilever 2 and the beacon module 1 can rotate relative to the fixed bracket 14, so that the cantilever and the beacon module can be mutually converted in the working state and the recovery state.

The rotation driving mechanism is installed between the first rotation shaft 3 and the fixed bracket 14, and is used for driving the first rotation shaft 3 to rotate.

The first rotating shaft 3 is driven to rotate by the rotation driving mechanism, and the beacon module 1, the cantilever 2 and the positioning module formed by the first rotating shaft 3 can rotate around the first bearing seat 4. As shown in fig. 4, when the positioning module rotates to a working state, the beacon module 1 is positioned in the middle of the track 200, so as to realize the function of a metro vehicle parking positioning mark; when the metro vehicle is overhauled at the position of the trench 300, a worker or overhauling equipment needs to travel in the trench 300, and at this time, as shown in fig. 5, the positioning module is rotated to a recovery state, and the whole positioning module is tightly attached to the upright post of the fixed support 14 or the side wall of the trench 300, so that the positioning module cannot become an obstacle.

In some embodiments, as shown in fig. 1 and 2, the rotation driving mechanism includes a motor 6, a second rotation shaft 7, and a transmission wheel set 8.

A cross bar may be further connected to the middle or upper portions of the two upright posts of the fixed support 14, and the motor 6 is mounted on the cross bar of the fixed support 14.

Two second bearing blocks 9 can also be mounted on the cross bar, the second rotary shaft 7 being fitted in the second bearing blocks 9 for rotary connection to the fixed support 14, and the second rotary shaft 7 being also in driving connection with the motor 6.

The transmission wheel set 8 is in transmission connection with the first rotating shaft 3 and the second rotating shaft 7 at the same time, and the second rotating shaft 7 drives the first rotating shaft 3 to rotate through the transmission wheel set 8.

According to the embodiment of the utility model, the motor 6 is used for driving the second rotating shaft 7 to rotate, the second rotating shaft 7 is used for driving the first rotating shaft 3 to rotate through the transmission wheel set 8, and then the positioning module is finally driven to mutually convert in the working state and the recovery state. The transmission is efficient and labor-saving, and the adjustment of the rotation direction and the locking of the rotation position of the positioning module can be realized by controlling the forward and reverse rotation and the start and stop of the motor 6, so that the positioning module is lifted or retracted. In particular, after the motor 6 is stopped, the self-locking of the motor 6 can be used for preventing the positioning module from rotating, namely, the motor 6 also plays a role in locking the position of the positioning module.

The drive pulley set 8 may be selected from the forms shown in fig. 1-3 comprising a driving pulley, a driven pulley and a drive belt. The driving pulley may be disposed on the second rotation shaft 7 by means of a flat key or interference fit. The driven pulley may be provided on the first rotation shaft 3 in the same manner. The driving belt is sleeved on the driving belt wheel and the driven belt wheel simultaneously.

The drive wheel set 8 may also be considered to comprise a driving gear and a driven gear (not shown in the figures). The driving gear may be disposed on the second rotation shaft 7 by means of a flat key or interference fit. The driven gear may be provided on the first rotation shaft 3 in the same manner. Power is transmitted through engagement of the driving gear and the driven gear.

The rotation speed ratio between the second rotation shaft 7 and the first rotation shaft 3 can be adjusted by only adjusting the diameter ratio of the driving pulley and the driven pulley or the gear ratio of the driving gear and the driven gear, whether the power is transmitted in the form of the driving pulley, the driven pulley and the driving belt or the power is transmitted through the driving gear and the driven gear which are meshed with each other, so that different motors 6 and different transmission wheel sets 8 are selected according to different positioning modules.

In order to fully exert the power of the motor 6, the embodiment of the utility model can also be provided with a speed reducer 5 between the motor 6 and the second rotating shaft 7 to match the rotating speed and enhance the torque.

Although the position of the positioning module after rotation can be limited by the motor 6, if the motor 6 is damaged, particularly after self-locking failure, the positioning module cannot be ensured to be in a working state, so that the parking positioning function of the metro vehicle cannot be completed. To prevent this unexpected situation, as shown in fig. 1-3, an embodiment of the present utility model may further include a first link 10, a second link 11, and a weight 13.

One end of the first link 10 is integrally connected with the second rotating shaft 7, the other end of the first link 10 is hinged with one end of the second link 11 through, for example, a hinge pin, and the other end of the second link 11 is hinged with the balancing weight 13 through, for example, a hinge pin. Therefore, after the self-locking failure of the motor 6, the balancing weight 13 can move downwards under the action of gravity, so that the second rotary shaft 7 is driven to rotate through the second connecting rod 11 and the first connecting rod 10 which are mutually hinged, and the positioning module is driven to rotate to a working state. Obviously, the torque that the balancing weight 13 can generate is greater than the torque that the positioning module needs to rotate to the working state, this can ensure the effect by increasing the weight of the balancing weight 13 on the one hand, and can adjust the lengths of the first connecting rod 10 and the second connecting rod 11 to ensure the effect on the other hand, because the calculation mode is well known to those skilled in the art, the mathematical relationship between these two is not repeated, and the skilled person can select according to the actual requirement.

When the motor 6 works normally, the rotation and the positioning of the positioning module are controlled by the motor 6, and the balancing weight 13 does not work. When the self-locking of the motor 6 fails, the balancing weight 13 falls down to enable the positioning module to rotate and keep in a working state without falling, so that the parking positioning function of the beacon module 1 is guaranteed, and the metro vehicle can normally enter the maintenance warehouse.

In order to prevent the counterweight 13 from swinging randomly, two vertically arranged slide ways 12 can be additionally arranged on two sides of the counterweight 13. The lower end of the slide 12 can be directly connected to the fixed bracket 14, and a slide groove is arranged in the slide 12, namely, the length direction of the slide groove is parallel to the direction of gravity. The two sides of the balancing weight 13 are provided with protruding parts, the protruding parts are positioned in the sliding grooves, namely, the balancing weight 13 is connected in the sliding grooves in a sliding manner, and the balancing weight 13 can only move up and down along the sliding grooves, so that the balancing weight cannot shake any more.

On the other hand, the length of the chute is preferably such that the following conditions are satisfied: as shown in fig. 4, when the balancing weight 13 slides to the lower end of the chute, the cantilever 2 (i.e., the positioning module) is in an operating state; as shown in fig. 5, when the weight 13 slides to the upper end of the chute, the cantilever 2 (i.e., the positioning module) is in a recovered state. This ensures that the positioning module does not turn over the head and not go out of place.

The angle through which the boom 2 (i.e., the positioning module) is turned when switching between the working state and the recovery state may be considered to be 90±15 degrees due to different conditions or different depths within the trench 300. That is, on the one hand, when the positioning module is in the working state, the included angle between the plane in which the positioning module itself is located and the plane in which the two upright posts of the fixed support 14 are located may be an acute angle, may be a right angle, may also be an obtuse angle, and is of course, the best case is a right angle. On the other hand, when the positioning module is in the recovery state, the included angle between the plane where the positioning module itself is located and the plane where the two upright posts of the fixed support 14 are located may be 0 degrees or may be within ±15 degrees. Such an angular setting facilitates flexible arrangement of the structure of the entire beacon rotation device 100, which can accommodate different operating environments.

To further optimize the structure of the entire beacon rotation device 100, the embodiment of the present utility model may further consider that the first link 10, the second link 11, the weight 13, and the slide 12 are disposed on the side of the fixed bracket 14 away from the cantilever 2. In this way, the first link 10, the second link 11 and the weight 13 do not interfere with the rotation of the positioning module when in motion.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above-described preferred embodiments should not be construed as limiting the utility model, which is defined in the appended claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the utility model, and such modifications and adaptations are intended to be comprehended within the scope of the utility model.
