Description

Uunderground barricade using reactive force of spring

The present invention relates to a buried type barricade using a spring reaction force, and more particularly, to a buried type barricade which is provided with a spring reaction force means and is configured to extend and retract while supporting a load of a barrier film together with a hydraulic cylinder, .

A barricade is an obstacle on the road that is temporarily installed to prevent the passage of people or vehicles. It is often installed and used to control the entrance and exit of illegal vehicles.

In recent years, the use of various barricades has been increasing in order to block the bombing of the national important facilities, and vehicles that attempt to intrusions.

There are various types of barcades used for this purpose. In recent years, the barcodes are usually not obstructed by the flow of vehicles passing through the roads. Underground buried barricades that can be controlled are increasingly being used.

Figures 9 and 9 show an in-ground buried barricade with a basic structure. The structure and operation of the hydraulic cylinder are shown in the figure. The hydraulic cylinder is connected between the receiving portion and the blocking membrane, and the hydraulic pressure is supplied from the hydraulic pump. The piston rod of the hydraulic cylinder is extended So that the shielding film is rotated about the hinge axis. When the barrier is rotated, the barrier that has been buried in the ground protrudes above the road surface, blocking the traffic of the vehicle.

Conventional buried barricades having such a structure are disclosed in Korean Utility Model Publication No. 98-010816 (name: Baricade for vehicle access control) and Korea Patent No. 10-529717 (name: burial type equipped with a single- Barricades).

However, the conventional embedding type barricade having the above structure is mainly described in terms of the high-speed rotation and rapid protrusion configuration of the barrier, and there is not disclosed a technique for reducing the energy consumption required to drive the buried barricade of high weight.

The most energy-consuming configuration of the energy consumed in the buried barricades is the energy required to drive the hydraulic pump to supply the hydraulic oil to the hydraulic cylinder. In order to reduce this, it is necessary to miniaturize the hydraulic pump and supply a small amount of the hydraulic oil supplied to the hydraulic cylinder. However, overcoming the technical difficulty that the hydraulic pressure can not be raised and lowered quickly, It is a fact that I can not. Therefore, there is a need for technology development.

SUMMARY OF THE INVENTION [0005] In order to solve the above problems, an object of the present invention is to provide a hydraulic cylinder, which comprises a hydraulic cylinder and a reaction force means together with a barrier block of a barricade, The present invention is to provide a highly efficient buried barricade capable of rapidly protruding or retracting a barrier membrane by using an extension force or a contracting force provided by a reaction force while reducing the energy consumption of the hydraulic motor by reducing the volume of the hydraulic motor.

According to an aspect of the present invention, there is provided a portable terminal comprising: a receiving part embedded in the ground; A shielding film protruding from the receiving part to block entry of the vehicle; A hydraulic cylinder having one end connected to the receiving portion and the other end connected to the blocking membrane to rotate the blocking membrane by extension or contraction of the piston rod; And a spring reaction force means provided between the receiving portion and the shielding membrane and cooperating with the hydraulic cylinder in operation to provide a reaction force against the load of the shielding barrier.

In a preferred embodiment, the spring reaction force means comprises: a guide cylinder in which a first fixing member provided inside the housing portion and a lower end portion are hinge-shaft-engaged; A guide rod which is hingedly coupled to a first end of the second fastener provided on the lower surface of the shield, and the other end of which is axially coupled to the guide cylinder; A reaction force spring provided around the guide cylinder and the guide rod to provide a reaction force to the blocking film; A first support portion provided at a lower end of the guide cylinder and supporting a lower end of the reaction force spring; And a second support portion provided at an upper end of the guide rod and supporting an upper end of the reaction force spring.

In a preferred embodiment, the reaction force spring may have an elastic force that contracts when a load of a blocking film is applied.

In a preferred embodiment, the spring reaction force means may be provided on each of the hydraulic cylinders on the central portion of the housing portion.

According to the present invention having the above-described characteristics, the load of the hydraulic cylinder can be reduced by allowing the hydraulic cylinder and the spring reaction force means to disperse and support the load on the barrier of the buried barricade, thereby reducing the hydraulic pump capacity of the hydraulic cylinder, Advantages,

Further, while the hydraulic pump is downsized, the spring reaction force means is always provided to provide a reaction force when the blocking membrane rises or falls,

In addition, since the hydraulic pump supplying oil to the hydraulic cylinder is miniaturized, the total energy required for elongating and expanding the barricade is consumed less, and the barrier of the same load operated by the conventional hydraulic pump can be rapidly projected or housed. This is a significant savings,

In addition, by providing at least one spring reaction force means, it is possible to freely install the installation position of the hydraulic cylinder in the storage portion of the buried barricade, thereby overcoming the limitation of space utilization and design constraints.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Sectional structure showing a contracted state structure of the spring reaction force means according to the example.

As shown in the figure, the configuration of the buried type barricade according to the embodiment of the present invention is such that a box-like receiving portion 11 is buried in the lower portion of a predetermined space portion of a road surface to be installed. In order to support a strong impact force generated when a vehicle collides with a vehicle, the storage unit is disassembled to have a larger area than the area of the land to be buried, and then the concrete is laid on the storage unit for foundation work. By the construction, the total weight buried in the ground is raised to increase the fixed bearing capacity. In addition, various pipes such as a drainage hole and an electric wiring are constructed at the time of the foundation work.

A shielding film 13 protruding from the hinge shaft 12 formed on one side of the storage unit buried in the ground is provided so as to control the vehicle passage according to the control.

A hydraulic cylinder 14 for extending or retracting the piston rod 141 of the hydraulic cylinder 14 connected to the lower portion of the blocking film 13 to rotate or project the blocking film is housed in the space inside the accommodation portion 11 Respectively.

A spring reaction force means (15) is provided between one point of the bottom of the receiving portion (11) and one point of the lower portion of the shielding film to provide a reaction against the load of the blocking film when the hydraulic cylinder operates.

Further, the joint link 16 is connected between one point of the bottom of the receiving portion 11 and one point of the lower portion of the blocking film, thereby preventing the blocking film from being bent backward when the vehicle collides with the blocking film. This joint link is a structure in which two or more links are connected by a pin. Normally it is folded. When the blocking membrane is rotated and protruded by extension operation of the hydraulic cylinder, the joint link is unfolded and climbed to control the height of the blocking membrane. As shown in Fig. The joint link is not shown in the accompanying drawings but is formed slightly inclined. Since the joint link is bent in the backward direction in a state of being straight up, the folded state is not naturally folded again unless an external force is applied. In addition, it is configured to be folded only when it is subjected to external pulling force.

Referring to FIG. 1, according to an embodiment, it can be seen that one hydraulic cylinder is provided at a central portion, spring reaction force means is provided at both sides thereof, and one joint link is formed outside each spring reaction force means . When the hydraulic cylinder is elongated, the barrier membrane rotates and protrudes around the hinge shaft. When the spring cylinder is extended, the spring reaction force means located at both sides of the hydraulic cylinder extend while supporting a part of the load of the blocking membrane. When the blocking membrane protrudes to the maximum If the external force does not act while keeping the joint link unfolded, the load of the shield is partially supported without being folded. Of course, the load of the main blocking film is provided by the hydraulic cylinder and the spring reaction force means.

The hydraulic cylinder 14 is provided with a hydraulic pump for supplying unillustrated oil to the hydraulic cylinder, an oil tank for storing the oil, and an accumulator for storing a predetermined amount of oil pressurized for instantaneous hydraulic pressure supply, When the oil is supplied from the pump or the accumulator to the lower space of the piston rod located in the hydraulic cylinder, the inflow oil extends the piston rod to rotate the blocking membrane fixed on one side of the hinge shaft in the upward direction, do.

On the contrary, when the hydraulic pump supplies oil to the upper side of the piston rod and the space inside the cylinder, the piston rod contracts and the other side of the blocking membrane, one side of which is fixed to the hinge shaft, rotates in the downward direction in which the receiving portion is located, .

The present invention is characterized in that the hydraulic pump for driving the hydraulic cylinder is configured to increase the energy efficiency by using a relatively small hydraulic pump than the conventional hydraulic pump. That is, a small hydraulic pump that supplies a small amount of oil to a hydraulic cylinder that protrudes or stores a shielding film having the same load is configured to reduce power consumption and oil amount.

The reason why the hydraulic cylinder according to the present invention can be operated at the same or faster speed than the speed at which the blocking membrane is used to project the relatively large capacity hydraulic pump using the small hydraulic pump is that the spring reaction force means 15, And the hydraulic oil amount due to the miniaturization is canceled and driven.

According to one embodiment, the spring reaction force means is constituted so as to extend and retract together with the assistance of the extension and contraction forces of the hydraulic cylinder while being operated on both sides of the hydraulic cylinder located at the center. Needless to say, the number of such spring reaction force means is not specified but can be increased or decreased as necessary.

Instead, the spring reaction force means should have a reaction force that can not raise the blocking membrane alone. That is, when the spring reaction force means is located on the upper portion and the load is applied, the spring reaction force means that the spring reaction force is naturally contracted at all times by the self weight of the blocking film.

The reason for using such a spring reaction force means that it must not operate as a load during the operation of the hydraulic cylinder because it always operates in conjunction with the hydraulic cylinder which is stretched and contracted while supporting the load of the barrier film constituting the buried barricade. If the extension force of the spring reaction means alone overcomes the load of the blocking membrane, the blocking membrane always protrudes. Therefore, a force for restraining the blocking membrane is required, which makes it difficult to control the normal extension of the hydraulic cylinder during operation of the hydraulic cylinder. This is because the capacity of the hydraulic pump must be increased because not only the force but also the force to shrink the spring reaction force means is required.

Accordingly, when the spring reaction force means having the elasticity of the level required by the present invention is used, the hydraulic cylinder can be rotated and protruded about the hinge axis with less force when the hydraulic cylinder is expanded or contracted. When the hydraulic cylinder is contracted, It is helped to be stored.

Specifically, the spring reaction force means 15 includes a first fixing member 111 fixed to the inner surface of the receiving part, for example, a side surface or a bottom surface, and a guide cylinder 151 having a hinge hole 1511 formed at a lower end thereof to be hinge- Wow; A guide rod 152 having a hinge hole 1521 formed at an upper end thereof and a shaft end coupled to the inside of the guide cylinder at the other end so as to be hinge-shaft-coupled to the second fixing member 131 fixed to the lower surface of the blocking membrane; A coil type reaction force spring (153) provided around the guide cylinder and the guide rod to provide a reaction force to the blocking film; A first support part 154 provided at a lower end of the guide cylinder to support the lower end of the reaction force spring to prevent it from coming off; And a second support part 155 installed at an upper end of the guide rod to support an upper end of the reaction force spring to prevent the reaction force from coming off.

A stopper 156 is formed at the upper end of the guide cylinder to prevent the guide rod from being pulled out of the guide cylinder by hooking the engaging portion 157 provided at the lower portion of the inserted guide rod.

The guide cylinder is cylindrical in shape such that its lower and upper portions are opened so that elastic force due to internal air compression and vacuum pressure due to air expansion are not generated. If the lower part is clogged, the guide rod is inserted into the upper part and is coupled to the inner surface of the guide cylinder. When the guide rod is descended, the air is compressed and elasticity is generated to prevent shrinkage. This is because a kind of vacuum pressure due to air is formed and it is hard to stretch.

The height of the reaction force spring in a state where no pressure is applied is equal to a height when the guide cylinder and the guide rod are extended to the maximum.

It is also sufficient that the height of the reaction force spring at the maximum shrinkage reaches the vicinity of the first fixture fixed to the inner bottom surface of the accommodating portion through the lower opening of the guide cylinder. Of course, such heights do not limit the present invention.

However, it is preferable that the height of the guide rod is formed so as to be larger than the height of the guide cylinder so that the reaction spring is sufficiently contracted at the time of descending and contracted at the same time,

Also, as described above, it is also important that the elastic membrane has such an elasticity that it can not lift the barrier membrane alone when the barrier film load is applied to the upper portion in the state of maximum contracting.

Hereinafter, the operation of the buried type barricade according to the present invention will be described with reference to FIGS. 1 to 7. FIG.

(Not shown) having at least one of various types of sensors composed of an optical sensor, an ultrasonic sensor, a speed sensor, or the like as a sensing means, or an operation of a barricade to control a vehicle entering the road by a barricade operator When a control unit for controlling operation is operated, a hydraulic motor (not shown) is operated to supply oil stored in an oil tank (not shown) or oil previously stored at a predetermined pressure to an accumulator (not shown) to the hydraulic cylinder.

The piston rod of the hydraulic cylinder overcomes the load of the blocking membrane and rotates the blocking membrane toward the upper side with the hinge shaft coupled to one end of the blocking membrane and one end of the receiving unit to be projected onto the road surface.

At this time, the spring reaction force means provided on both sides of the hydraulic cylinder elevates the blocking film and changes from a contracted state to a stretched state to provide a reaction against the load of the blocking film, thereby assisting the operation of the hydraulic cylinder. Thus, the hydraulic cylinder quickly raises the shielding film with a small force in accordance with the load of the shielding film supported by the spring reaction force means. Therefore, the capacity of the hydraulic pump that supplies the hydraulic pressure to the previously used hydraulic cylinder may be used as a small-capacity hydraulic pump.

If the joint is rotated and projected as described above, the joint is extended to the joint link, and if the external force does not act on the shield, a stable projecting state is maintained.

When the control condition is ended and the barrier is lowered, the hydraulic pump does not descend while supporting the load of all the blocking membranes, and some load is supported together with the spring reaction force means located on both sides of the hydraulic cylinder. At this time, since the external force acts, the articulated link is folded down in a folded state. In this way, since the hydraulic cylinder, as well as the spring reaction force means, are provided during the downward movement, the hydraulic cylinder shrinks while supporting the load of the smaller shielding film. Therefore, the amount of oil supplied to the hydraulic cylinder for shrinking is small.

In addition, the spring reaction force means which is lowered while supporting the shielding film also descends and is housed. Further hydraulic contraction force is provided by the hydraulic cylinder, so that it is lowered to the storage portion more quickly.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents. Of course, such modifications are within the scope of the claims.
