Abstract

A method and a device for controlling the speed of rail vehicles are used for deceleration and acceleration of vehicles at hunting yards. During the process of controlling the speed a pressure element (1) is introduced into an annular hollow (3) of the wheel (2), which is formed by the disk of the wheel (2), by the hub (5) and by the inner radial surface (6) of the wheel's rim and which is located on the inner or outer side of the wheel, so as to apply a force effect to any point of one of the two areas (7) of the inner radial surface of the wheel's rim which are located on both sides of an imaginary plane (a-a) passing through the axis of the wheel and its point (B) of contact with the rail. The pressure element (1) is so shaped as to ensure its free entry into the annular hollow and is mounted on a carriage displaceable along the railway line. In this way, the value of the force effect of the pressure element is not limited by the weight of the vehicle.

Description

[Detailed description of the invention] Methods and devices for controlling the speed of railway transportation facilities Technical field The present invention relates to railway transportation facilities, and more particularly to a method and method for controlling the speed thereof. Relating to apparatus for implementing the law.

Background technology In order to operate the rail yard (or hump) optimally, it is necessary to (covered vehicles, long vehicles, tank vehicles, etc.), e.g. deceleration, acceleration, stop, or must be able to effectively control the starting of stopped transport vehicles.

Traditionally, there are many methods and devices used to control the speed of rail transportation vehicles. , is publicly known.

Between two beams placed along both sides of the rail of a rail transport vehicle. Methods of slowing down rail transport vehicles by impeding wheel motion are well known.

However, with this method, the actual performance of the transport vehicle when starting with the delay mechanism removed The actual speeds are very different. This phenomenon is caused by the coefficient of friction between the "wheel side/beam surface". This is due to the fact that the This is not only due to adhesion, but also due to temperature changes and other factors. It is. Moreover, this method can, in principle, be used to increase the speed of transport vehicles. cannot be used. Therefore, it is used in rail yards to control (reduce) the speed of transport vehicles. Other methods and devices for achieving speed and acceleration) include at least one pressing member and The interaction force between the wheels of the transport vehicle is adopted, and the interaction is applied to the mechanism of the wheels. It must be completed within the range of mechanical trajectory (motion path) (for example, r zheleznye Dorogi MiraJ/World Railways/Magazine, 1981 2003, No. 9, pp. 17-18.27).

The basis of the above-mentioned method for controlling the speed of railway transport facilities is that in order to carry out the above control The area of the lower flange of the outer surface of the wheel rim within the section of track selected for (In the case of acceleration, it is behind the train in the direction of movement, and in the case of deceleration, it is in the front. ) by its suppressing members (conveyor rollers, rods, screw surfaces). ), the above member is installed in the travel path of the wheel, and this In other words, they are placed in front of or behind the wheel (e.g. For example, see FRG Patent No. 1530302, International Classification Number 3B61 j3106. (want to be).

When this method is realized, the effect of the force produced by the pressing member is However, in practical terms, it is independent of the above friction constant, and the value of the effect of the above force is strictly proportional. It is convenient from the point of view of This method was adopted as a prototype.

What should be noted here is that the value of the force acting on the above wheel based on the above method is extremely is limited to a narrow range, and this range has a relation to this of the force of said transport vehicle. The point is that it is controlled by the component force applied to the wheels. If this range is exceeded, the above wheels running over adjacent pressing members or resulting in derailment of said transport vehicle. Become.

This is due to the fundamental limitations of the above-mentioned method, which makes it impossible to operate the above-mentioned device without incident. In order to It is et al. This vertical force is the potential for interaction with the “light shaft” (i.e. empty vehicle). It must not exceed 17 kilonewtons, and this condition must be met. This is extremely difficult and impossible even for trains made up of very few cars. Even.

A device for implementing the above method is used for moving passenger cars and other railway vehicles. Carriage used. This device has two pairs of pressure rollers. can move forward and backward across the track. The pair of suppression rollers mentioned above are When moving forward or backward, the distance consisting of the front part of the wheel is separated, and at other times the above wheel The pressure rollers are spaced a distance apart from the rear of the wheels, and both of these pressure rollers are within the travel path of the wheels. It is within the surrounding area.

The pressure roller can act on the lower rear and lower front parts of the flange of the wheel. The working range corresponds to 1/4 of the flange. The above device itself is The driver moves along the auxiliary rail laid inside the rail and parallel to the above rail. activated by a cable connected to the operating device.

If the vehicle moves faster than the carriage with the wheels between the extension rollers. , the flange begins to press down on the roller in front of the wheel. this car Both potential energies are transferred to the carriage via the rollers, and then transferred to the carriage. The energy is transmitted to the drive device via the cable, and the drive device transmits the energy. Absorb.

Therefore, the speed of the vehicle is less than the speed of the carriage.

The vehicle moves slower than the carriage above, with the wheels between the extendable rollers above. In this case, the pressure roller on the rear side of the wheel is placed in the lower rear quarter of the wheel Start pressing down on the corresponding above flanges. In addition, the energy from the drive is sent to the wheels via the lower roller, carriage, and cable. Therefore, the speed of the vehicle is of the same order as the speed of the carriage.

However, 1, the interaction between the above-mentioned pressing member and the wheel flange (this (both in the case of deceleration and in the case of acceleration), an emergency situation associated with a component force directed vertically upwards exist. Therefore, it is necessary to strictly limit the magnitude of such interaction forces. Ru. This is because the above vertically upward force is due to the weight applied to the corresponding axle. If the force is exceeded, there is a risk that the wheel will come off the top of the rail and the vehicle will derail. This is because you must be prepared for this. Therefore, such a control action is carried out Sufficiently eliminate danger.

Disclosure of invention An object of the present invention is to provide a method and device for controlling the speed of a railway transportation facility. In particular, in this method and apparatus, the suppression member and the wheel interact and the The interaction is such that the force applied by the suppressing member to the wheel is applied to the corresponding wheel. Furthermore, the above method is not limited by the weight of the vehicle being used; By presetting the speed control accuracy at the same time, even when the size is This completely eliminates the risk of vehicle derailment.

The above objective is achieved by the following method. That is, ; one or more pressing members and Railways that use forces that interact with the wheels of a conveyance vehicle within the mechanical track of said wheels. In a method for controlling the speed of a transport facility, according to the invention, the pressing member is introduced into the cavity of the annular space from the outside or inside of the wheel, and the cavity is connected to the vehicle. Formed by the wheel disc and the circular inner surface of the hub and the wheel rim above, the above force is one of the two areas of the circular inner surface of the rim of the wheel depending on the direction of the force; Acts on any point within the range, said range is on both sides of the imaginary plane, and is connected to the axis of said wheel. , a railway transportation facility characterized in that said wheel crosses a point where said wheel contacts its rail. is a method for controlling the speed of Therefore, inside the circle along the rim of the wheel above, The length of each of the above ranges on the inside of the surface is drawn from the center of the wheel and is the same as the wheel. Said car formed by a line opening at an angle of 2 degrees and 145 degrees from the point of contact with the rail. It can correspond to the length of the arc of the ring. In a most preferred embodiment, the above The length of each of the above ranges inside the circular inner surface along the rim of the wheel is 2 degrees to 90 degrees from the point of contact between the wheel and the rail, drawn radially from the center It is formed by a line that opens at an angle of .

A device for carrying out the above proposed method produces an interaction force with the above wheels. and one or more pressing members for controlling the mechanical trajectory of the wheel. and the member controls the positioning device of the carriage and the pushing member. The carriage is connected to the drive device, and the carriage is connected to the line. In the device for controlling the speed of railway transport facilities that can move along the road The pressing member is attached to the carriage, and the carriage is attached to the vehicle. It is installed so that it can be introduced into the cavity of the annular space from the outside or inside of the ring, and The cavity is formed by the disc and hub of the wheel and the circular inner surface of the rim of the wheel. The above-mentioned member is moved to the above-mentioned car in any range of the two ranges on both sides of the virtual plane. The circular inner surface of the wheel rim corresponds to said member, and said imaginary surface coincides with said wheel axis. , the point where the wheel contacts its rail.

The length of each of the above ranges inside the circular inner surface of the rim of the above wheel is pulled from the center and opened at an angle of 2 degrees and 145 degrees from the point of contact between the wheel and rail. Corresponding to the length of the wheel arc formed by the line, in a preferred embodiment , the above angle is equal to 2 degrees to 90 degrees.

The bearing member of the carriage is housed between the upper part and the base of the lateral rail, The one that is attached so as to have a force that makes contact with the top of the rail or its base. Appropriate. Furthermore, the carriage itself is mounted so that it can move vertically. You can also do it.

The pressing member is introduced into the cavity of the annular space, and the pressing member is inserted into the circular space of the rim of the wheel. Applying pressure with the pressing member to any point in one of the ranges formed by the inner surface. causes a pressing action on the wheel which is not limited by the value of the weight applied to the wheel. can be added to. This means that this moving force includes a vertical component. Especially in the range of 2 degrees to 90 degrees from the point of contact between the wheel and the rail. This is because the moving force does not include a component force in the vertical direction. express this in other words Then, any force applied by the suppression member will cause the wheel to move against the rail 90. A force applied at an angle of less than 2 degrees will act to force the wheel against the rail. this is clearly an advantage of the present invention. The reason is that the wheels of the transportation vehicle (the above vehicle This is because it applies a force to the wheel (independent of its weight) that does not pose a risk of causing an accident. , this method sufficiently decelerates the vehicle in any practical control mode, This is because it can accelerate, start, stop, and secure the vehicle to the track. This is because all these operations can be performed without the risk of the vehicle derailing. this By adopting the method, any increase in the acting force applied to the wheel is absorbed by the excess safety factor. will be collected. Therefore, it is difficult to lower transport vehicles etc. on the tracks from the hump. When maneuvering a vehicle, the speed of the vehicle is controlled in the same way as normal vehicle maneuvering within the yard. As a rule, the speed is very slow (0 to 35 km/h). meters per hour). Looking at it this way, the static load applied to the wheels is greater than the dynamic load. It is well known that the width becomes smaller. Speed of 120 to 160 kilometers per hour In this case, the dynamic load is many times the maximum allowable static load. Therefore, the vehicle The safety factor when operating a vehicle at a speed of 40 kilometers per hour is extremely large.

Another thing to note is that according to this method, the value of the acting force is practically limited. This is only when accelerating, so there is a risk of damage to the vehicle and the items it carries. This method can be easily applied to vehicles.゛Things to be more careful about means that the pressing member acts on a point inside the lower semicircle on the inner surface of the wheel rim, and The point is on an imaginary plane, and this imaginary plane crosses the axle of the wheel and is connected to the wheel. If it crosses the point of contact with the ball, the desired effect cannot be obtained. The reason , the force applied to the above point does not include a horizontal component and does not produce the desired control effect. (in this case, the resistance does not increase due to the force in the opposite direction of the rotation of the wheel) It is. What should be added is that in this case, the contact point between the wheel and the rail The horizontal component force in the range of 2 degrees measured with reference to is so small that it can be ignored. That's true.

Additionally, it should be considered that the acting force is on the axle in the face of the inner rim. When applied to a certain range, the above acting force forms a component force in the vertical direction, and this vertical component directional forces tend to act to pull the wheel away from the rail.

Therefore, within the circular inner surface of the wheel rim, based on the point of contact between the wheel and the rail, Applying the above-mentioned force at a point exceeding 145 degrees when measured as standard is not suitable for the above-mentioned purpose. Contrary.

In addition, the interaction surfaces with different curvatures (the circular inner surface of the wheel rim and the wheel flange above) method and equipment used as the above prototype having Compared to the above-described wheel rim, the present invention has This shape has the same curvature as the circular inner surface of the wheel. (therefore, the above working surface is more optimally matched), all other factors being equal. Finally, the contact stress is significantly reduced and therefore the friction is reduced, making the above device more efficient. Extends lifespan.

The dimensions of the pressing member introduced into the cavity of the circular space are based on the initial dimensional tolerance of the wheel. , the friction between the wheels and the rails, and other parameters related to the specified shape. It must be possible to properly align the above components for the purpose of the data.

In the present invention, in order to withstand all loads, a vertical Only the vertical action, horizontal action, and action across the running rail are used. It will be done.

This means that the bearing member of the carriage member is connected to the head and base of the traveling rail. This is because it is installed so that it can be accommodated between the Please be careful about this point. The critical point is the flux of the above force when the vertically applied load reaches its maximum value. The force is to close along the shortest path, and the flux of this force is The above wheel, the above upper rail, the head surface, the above lower rail head surface, the above The flux of this force is carried by a carriage that can move vertically above the bearing member. It is completed by using . Through the engineering solutions explained above, the entire structure Materials used to manufacture can be generally saved.

Brief description of the drawing The invention relates to a method for controlling the speed of a railway transport facility, which will be explained below with the help of figures. , and an apparatus for carrying out the method.

Figure 1 shows the direction of motion of the wheel by arrow A, which is housed in a circular cavity in the wheel rim. 2 is a schematic diagram of a pressing member introduced into the wheel pair from the outside and inside of the wheel pair. A schematic diagram illustrating a pressing member that Figure 3 shows the basics of the speed control device of a railway transportation facility in its initial position after being drawn into the line. shape, FIG. 4 shows a suppression member introduced into the cavity of the annular space of the wheel, in the active position; The apparatus according to FIG. 3 is shown, and FIG. 5 is a top view of the apparatus according to FIG.

BEST MODE FOR CARRYING OUT THE INVENTION The basic points of the method of controlling the speed of railway transportation facilities proposed by the present invention are as follows. Therefore, it is achieved. One or more pressure members 1 (FIG. 1) are mounted on the outer side of the wheel 2 ( 2a) or from the inner side (Fig. 2b) of the disc 4 of the rim 2 of the wheel, the hub 5 and into the annular space cavity 3 formed by the circular inner surface 6.

The pressure member 1 introduced into the cavity commands the acting force, i.e. inside the rim of the wheel. A constraint on an arbitrary point in one of the two ranges 7 (Fig. 1) of the circular surface 6 of The operation is started based on motion or acceleration, and the above range is on both sides of the virtual plane ra-aJ. , and this imaginary plane crosses the axle O and the point B where the wheel contacts the rail 8.

The pressure member 1 is located on the inner circular surface of the wheel rim 2 immediately adjacent to the plane ra-aJ. When acting on surface 6, the horizontal vector of the acting force is relatively small, so the transport In order to improve the efficiency of controlling the speed of the vehicle, the areas 7 are respectively connected to the rims 2 of said wheels. It has a length corresponding to the arc of the circular inner surface 6, and this arc is connected to the lines b i, b i Therefore, this line b1. b1 crosses the center of the above wheel, and at the above point B, the above It opens 2 to 145 degrees with reference to point B where the wheel contacts the rail 8. In addition to the above The applied force crosses the center of the wheel, and the contact point B between the wheel and the rail 8 is the reference point. line b1. which opens at angles of 2 degrees and 90 degrees. The above wheel rim defined by b2 When acting within the area 7 of the circular inner surface 6 of the wheel, the wheel The train is pressed against the rail by a direct force, and in this state the force is applied to the formed train. acts on the wheel without limiting the above force which makes the weight equal, and this weight is The wheels act to prevent derailment of the organized train.

From the suppressing member 1 to the circular inner surface 6 of the rim 2 of the wheel, cross the center of the wheel. Line b2 that opens 90 degrees to 145 degrees. A force is applied to the range 7 defined by b1. The vertical component of the above acting force increases when the wheel is pushed away from the rail. tend to separate and therefore this value is the force of the vehicle weight applied to the wheels. is limited by the value that makes it equal. The force from the suppression member is applied to the rim of the wheel. Add to the circular inner surface 6 at an angle of 90 degrees measured from the contact point between the wheel and the rail. The applied force above does not include any vertical component force, and in this situation the Control hardening (acceleration-braking) reaches its maximum value.

During deceleration (braking), the pressing member 1 is placed behind the circular inner surface 6 of the rim of the wheel. 7 (with respect to the direction of movement of the vehicle), whereas during acceleration , the suppression member 1 (indicated by a broken line) is located in the front area of the circular inner surface 6 of the wheel rim. 7.

Hub 5. and formed by the circular inner surface 6 of the rim of said wheel. The member 1 can be inserted into a cavity 3 having an annular space in which the member 1 is inserted. It has a shape that allows it to be introduced into the cavity 3 without being obstructed, and the introduction is carried out by the wheel 2. It is carried out from the inside of the wheel 2, and crosses the contact point B between the axis of the wheel 2 and the wheel and the rail 8. At any point within the above two ranges 7 (Fig. 1) on both sides of the virtual plane "a - a J" , suitably matching said member to the circular inner surface 6 of the rim of said wheel.

Not only the specified characteristics of the shape of the wheel (its rim, disc and hub) Depending on the structure of the engaged rail portion, the wheel 2 (Fig. 2a) or the pair The pressing member can be more appropriately introduced into the cavity of the wheel from the outside of the wheel. It is clear that it is coming. In order to satisfy this requirement, the above device must be A carriage that can move along the base of the running rail and a position that goes beyond the rail. The pressing member and the rim of the wheel on the outside of the wheel (or wheel pair) an additional guide member capable of accepting forces of interaction with the circular inner surface of the must be established.

Various suitable devices are used to achieve the introduction of the suppression member from the outside. Therein, there is the above-mentioned pressing member in the shape according to the present invention.

It has a contacting shape, and its surface also faces the inner part of the rail.

An axis 15 is attached to the frame 10, parallel to the rail 8, and parallel to the axis supports an arm 16 attached to this shaft and the above-mentioned pressing force in the form of a roller. Support member 1. The pressing member 1 can be rotated by a shaft 17 on the arm 16. It can be installed as shown. The shape and dimensions of the pressing member 1 are as follows: The axis of rotation 17 is adjusted so as to match the outer shape of the circular inner surface 6 of the rim of the ring, and the rotating shaft 17 is It is selected such that in the working position it is parallel to the axes of the wheel pair. From this point of view, The length of the generating line of the member 1 is determined by the contact between the pressing member and the circular inner surface 6 of the rim of the wheel. Try to form the maximum matching area within the range. The arm 16, the pressing member 1 , and the dimensions of the shaft 17 such that the arm 16 rotates to its working surface and At this point, the suppressing member 1 is compressed by the circular inner surface of the rim 18 of the wheel 2, and When entering the cavity 3 formed by the disc 4 of the ring 2, the pressing part The working surface of the material 1 and the front area and the circular inner surface 6 of the rim 18 of the wheel 2 and the rear region 7.

The hydraulic cylinder 21 is attached to the frame 10 by means of an arm 19 and a shaft 20. The rod 22 is connected to the arm 16 by a shaft 23, and the fourth Rotate said arm around axis 15 to a preset angle as shown in the figure. let Both chambers of the hydraulic cylinder 21 are connected to a flexible hose 24 (the first 5) is connected to the pump installation (i!25).

A detector 26 is provided to control the operation of the pump facility 25 and cylinder 21. and the detector acts on the support frame 10 at the location of the wheel 2. is set to The detector 26 controls the position of the pressing member. Any conventional shape may be used as long as it can be used for this purpose.

The rod 29 of the driving hydraulic cylinder 30 is connected to the above-mentioned It is attached to the frame 10.

The eye 31 of the hydraulic cylinder 30 is connected to the arm 33 by a shaft 32 and The arm is firmly fixed to a fixed base plate 34.

Both chambers of the oscillating hydraulic cylinder 30 have flexible high-pressure hoses 3 5 to the pump facility. The flow rate, direction, and pressure of the liquid are , is set by a known control device (not shown).

The above-mentioned device and its constituent parts are installed to correspond to a railway transportation facility, Its dimensions are based on the interior of various railway structures, their gaps, and their limits (or other Depending on the vehicle used, the above gaps and limits are determined according to the external shape of the vehicle. is determined solely by the components of the overall device, which components are connected to the vehicle. It is a shape that directly interacts with the

Therefore, the above-mentioned components within the internal space formed by the above-mentioned overall dimensions. Positioning relates to the positioning of the vehicle components to be interacted with and therefore The possibility of contact with other parts of the vehicle is completely eliminated.

The above conditions can also be applied to other embodiments of the above device.

Vertical movement of the carriage device and the upper part between the head and base of the traveling rail. The location of the carriage assembly bearing members is determined for the strongest drive cuff flux. the shortest loop of the wheel, i.e. the circular inner surface of the wheel rim - above the rail head Surface - Lower surface of the above rail head - Bearing member of the above carriage - Above suppressing member can be formed.

Almost all of the above-mentioned members are involved in the transmission of the above-mentioned driving cuff flux which acts in compression. . Therefore, the overall shape of the device generally reduces the amount of material used for the device. and improve the reliability of its operation.

The method described above is achieved by the operation of the above device, and the method is realized in this way. The law is better understood by an example. The operation of the above device is as follows. achieved.

A detector 26 indicating the position of the wheels 2 when a first pair of wheels approaches the device. An output signal is sent to the pump equipment 25, and this signal is transmitted via one of the hoses 24. The pressure in the chamber of the hydraulic cylinder 21 is increased.

This pressure causes the roller drum 22 to rotate around the shaft 15, causing the The arm 16 rotates from its idle position to its operating position. Therefore, the above pressing member The first type is formed by the circular inner surface 6 of the rim 18 of the above wheel, the hub 5 and the disc 4. Enter into Cavity 3.

The detector 26 and the yard control are governed by the speed of the pair of wheels; It is also governed by the speed of the rolling stock on that railway, and said speed is relative to said rail section. The detector 26 and the control device of the rail yard move the pressing member 1 into the air. Introduce it into cave 3. If it is necessary to increase the speed of the trains organized above ( In other words, when it is necessary to accelerate the movement of the train, the pressing member 1 Located in the semi-circular part (with respect to vehicle motion) of the front half of said wheel. Speed of the above vehicle (i.e. when it is necessary to decelerate the motion of the train mentioned above) , the suppression member 1 is a semicircular portion in the rear half of the wheel (with respect to the movement of the vehicle) It is in.

When the speed of the train above corresponds to the speed selected for the section of rail, The control device of the rail yard does not output a command signal, so the vehicle does not move at the speed mentioned above. move freely over the speed control device without interacting with the speed control device.

If the vehicle moves at a speed slower than the prescribed speed on the position of the above rails, , the control device of the railyard immediately reacts and sends a corresponding command signal to the hydraulic system. The working fluid of the hydraulic system is sent to the appropriate chamber of the cylinder 30, and the working fluid of the hydraulic system is supplied to the pump equipment ( ii25 starts moving to the hydraulic cylinder via the hose 35, and then As a result, the rod 29 is connected to the frame 10 and the pressing member connected thereto. Push in the direction of movement of the vehicle mentioned above. The speed of the passing frame 10 is determined by the speed of the frame 10 passing through the pump. The equipment sets a predetermined optimum speed at the point at the yard.

Further, the pressing member, while moving inside the cavity, presses a circle on the rim of the wheel. Reach the front semicircular part of the inner surface of the shape and press the area 7 with the preset force. pressure starts, so that said wheel 2, together with its entire vehicle, reaches a predetermined The rod 29 is accelerated until it reaches a certain speed, or the rod 29 is made according to the distance traveled. The speed is increased until the frame 10 reaches the end of the range to be moved.

When said vehicle moves at a faster speed than said carriage member, said wheel rim The rear surface of the circular inner surface 6 is rotated by the above-mentioned pressing member and begins to press it, and the upper Releases a portion of the energy stored in the train.

The above vehicles, in their course of mutual movement, convert their energy into velocity, and their velocity is , set by said drive device until equal to the speed of said carriage device. It will be lowered as expected.

Thereafter, a command signal is sent to the pump equipment 25 from the control device of the train formation yard. sent to. The signal indicating the pressure in one chamber of the cylinder 21 decreases; In contrast, the pressure in the other chamber of the cylinder is applied to the shaft by the rod 22. 16 to rotate and raise the arm 16 to return the arm to its initial position. 3), this allows the pressing member 1 to be removed from the inner surface formed on the rim of the wheel 2. Pull apart. This operation is performed until the speed of the train formed above reaches a predetermined value. Even if it is not possible, it is performed when the frame reaches its limit position.

Next, the wheels of the above vehicle continue to rotate while increasing (or decreasing) their speed until do. The above-mentioned control device controls the pressure in the chamber of the above-mentioned hydraulic cylinder 30 and controls the pressure in the chamber of the hydraulic cylinder 30. As a result, the frame 10 returns to its initial state, so that the device It becomes possible to interact with the wheel pair.

When the above device includes two pressing members, the operation is almost the same as the above, and there is a difference. The point is that interaction occurs between the wheels of the wheel pair and the two rollers. That's all. Therefore, the above allowable force interaction values are used for the above contact points. It should double before reaching the specifically specified pressure.

In this way, the efficiency of the above control interaction is doubled for all subsequent results. can be increased.

Hydraulic drives have practically unlimited utility and can be used to approach optimal parameters. The control characteristics of the characteristics of When used with electronic control equipment, the accuracy and efficiency of the equipment can be activated.

The method described above also applies to many other devices for rail transport vehicles (vehicle restraint systems). It can be applied to the development of fixed devices, fixing devices, buttresses, etc.).

Therefore, the above proposed method and apparatus can be used to improve Provides equipment for handling focused on road transportation facilities. This means that the control Significantly reduces the amount of equipment used in the operation and therefore reduces the amount of material required for mechanization of the operating area. Significant savings not only in material consumption, but also in man-hours and overall equipment manufacturing costs. Can be done.

Industrial applicability The method and device proposed here can be used to monitor the speed of vehicles and small vehicles, as well as how to operate them. To change the speed of movement of rail transport vehicles without drive units in accordance with the Act, i.e. The international research report can be used to set its deceleration, acceleration, stop, and movement.
